The same problem exists with the fruit carrying net disclosed in chinese patent CN 104686072 a, which also has the effect that the fruit is stuck in the net bag and cannot be normally buffered. Generally speaking, the high-altitude fruit picker for conveying fruits through the net bag in the prior art has the problems of clamping and abnormal buffering, and also has the problem that the root branches of the fruits cannot be placed in an effective shearing area

Detailed Description

The invention is further described with reference to the following figures and detailed description.

As shown in the figure, the high-altitude fruit picker comprises a supporting rod 1, wherein a guide ring 2 for fruits to pass through is connected to the supporting rod 1, a plurality of layers of buffer nets 3 are arranged below the guide ring 2, the buffer nets 3 are arranged along the length direction of the supporting rod 1, a plurality of swing rods 4 are rotatably connected to the guide ring 2, for example, the number of the swing rods 4 is 12 in the embodiment, two adjacent swing rods 4 are connected through shielding cloth, the fruits can be prevented from falling from gaps among the swing rods 4 when falling through the shielding cloth, and the plurality of swing rods 4 are uniformly distributed around the axis of the guide ring 2; the buffer net 3 is woven by a plurality of elastic ropes, wherein the elastic ropes are ropes which have certain elasticity and can be contracted and deformed, specifically can be rubber bands, elastic ropes and the like, and the edge of the buffer net 3 is connected to the swing rod 4; a vibration ring 5 is arranged above each buffer net 3, and the vibration ring 5 is connected to the guide ring 2 through a vertical rod 6; the vertical rods 6 are uniformly distributed around the axis of the guide ring 2, the upper ends of the vertical rods 6 are connected with the guide ring 2, and the lower ends of the vertical rods 6 are connected with the vibration ring 5; in addition, the vibration ring 5 below the first vibration ring 5 is also connected with the vibration ring 5 above through the vertical rod 6, that is, the vibration ring 5 is fixedly connected to the guide ring 2, and the distance from each vibration ring 5 to the guide ring 2 is unchanged; a pull rope 7 for driving the swing rods 4 to rotate simultaneously is wound at the upper ends of the swing rods 4, a winch for tightening the pull rope 7 is arranged on the support rod 1, and a tension spring 8 for driving the swing rods 4 to abut against the outer peripheral wall of the vibrating ring 5 is wound below the guide ring 2; when the oscillating bar 4 abuts against the vibrating ring 5, the distance from the buffer net 3 to the vibrating ring 5 is greater than zero, that is, in this state, a gap is left between the buffer net 3 and the vibrating ring 5; the supporting rod 1 is rotatably connected with an upper blade 9 and a lower blade 10 which are matched with each other for shearing above the guide ring 2, the upper blade 9 is provided with an arc-shaped upper hook rod 11, and the lower blade 10 is provided with an arc-shaped lower hook rod 12; when the upper blade 9 and the lower blade 10 are in a far state, the upper blade 9, the upper hook rod 11, the lower hook rod 12 and the lower blade 10 form an annular structure, the annular structure is positioned at the periphery of the guide ring 2, and the support rod 1 is provided with a power device for driving the upper blade 9 and the lower blade 10 to rotate simultaneously. Wherein, when the upper blade 9 and the lower blade 10 begin to rotate, the upper hook rod 11 and the lower hook rod 12 are firstly matched, the upper hook rod 11 and the lower hook rod 12 can push the fruit root branches far away from the support rod 1 to the position close to the support rod 1, as shown in fig. 9, in the relative rotation process of the upper hook rod 11 and the lower hook rod 12, in the vertical direction, the joint between the upper hook rod 11 and the lower hook rod 12 is continuously close to the support rod 1, namely, in the process of converting from the state a to the state B, the fruit root branches are gradually pushed to the right.

Wherein, the principle that the buffer net 3 is lifted by the swing rod 4 is as follows: when each oscillating bar 4 abuts against the vibrating ring 5, the oscillating bars 4 and the buffer net 3 are in a solid line state; when the oscillating bar 4 is separated from the vibrating ring 5 after rotating, the oscillating bar 4 and the buffer net 3 are in a dotted line state; the reason is that the intersection point of the swing rod 4 and the buffer net 3 is unchanged, the hinge point 14 of the swing rod 4 and the guide ring 2 is also unchanged, and after the swing rod 4 rotates, the point of the intersection point projected to the vertical direction deviates, and the projected point is raised; that is to say, the original buffer net 3 is located at the CF height, and after the swing rod 4 rotates, the CF rotates to the CD position, so that the vertical projection of the CF becomes CE, that is, after the swing rod 4 rotates, the buffer net 3 is located at the CE position, and further the buffer net 3 is raised by the EF height value; the vibration ring 5 is fixedly connected to the guide ring 2 through the vertical rod 6, namely the distance between the vibration ring 5 and the guide ring 2 is not changed, and the distance between the buffer net 3 and the guide ring 2 is reduced by EF, so that the buffer net 3 collides with the vibration ring 5 in the lifting process to cause fluctuation.

The pull rope 7 penetrates through the upper end part of each swing rod 4, the pull rope 7 is in an annular structure on each swing rod 4, the annular structure is parallel to the guide ring 2, a support 13 for the pull rope 7 to penetrate through is arranged on the guide ring 2, and the winch is arranged on the support 13. The pull rope 7 penetrates through each swing rod 4, so that the pull rope 7 can drive each swing rod 4 to swing when tightened, and further the buffer net 3 below is opened, and grid openings on the buffer net 3 are enlarged; in the device, the size of the mesh openings in the buffer net 3 is determined not by the impact force of the falling fruits but by the swing amplitude of the swing rod 4; moreover, the device buffers the net 3 the net not only can the grow, still can raise and take place the striking with the vibrations ring 5, and then stir buffer net 3 through this striking and take place undulant, make the fruit that is located on buffer net 3 take place the uncertain motion, take place uncertain relative motion between fruit and the buffer net 3 promptly, this has just increased fruit and has carried out the probability that matches with each net on the buffer net 3, further improve the probability that fruit passes buffer net 3, avoid taking place the fruit joint at one deck buffer net 3 and can't get into next floor buffer net 3. Set up the leading wheel on support 13, stay cord 7 is around adorning on the leading wheel, and then leads the atress direction of stay cord 7 for the transmission of whole stay cord 7 is more smooth and easy.

Each oscillating bar 4 is positioned at the periphery of the guide ring 2, and the oscillating bars 4 are rotatably connected to the guide ring 2 through hinge points 14; the pull rope 7 is located above the hinge point 14, and the tension spring 8 is located below the hinge point 14. Specifically, when the pull rope 7 is tightened, the swing link 4 located above the hinge point 14 is gathered, and the swing link 4 located below the hinge point 14 is in a spread/extended state; after the pull rope 7 is loosened, the swing rod 4 below the hinge point 14 is gathered under the action of the pressing force of the tension spring 8 until the swing rod 4 abuts against the vibrating ring 5, and the swing rod 4 above the hinge point 14 is also reversely reset. Here, the vibration ring 5 not only plays a role of striking the buffer net 3 to shift the buffer net 3 to fluctuate, but also plays a role of limiting each swing rod 4.

Each oscillating bar 4 is provided with a circular ring 15 at the same height, and the tension spring 8 penetrates through the circular ring 15 on each oscillating bar 4, that is, the plane where the tension spring 8 is located is vertical to the axis of the circular ring 15, so that the pressing force of the tension spring 8 on each oscillating bar 4 is equal.

The power device is characterized in that a motor is arranged on a support rod 1, the output end of the motor is connected with a transmission wheel 16, an upper arc-shaped rack 17 taking the support rod 1 as the center of a circle is arranged on an upper blade 9, a lower arc-shaped rack 18 taking the support rod 1 as the center of a circle is arranged on a lower blade 10, and the transmission wheel 16 is meshed with the upper arc-shaped rack 17 and the lower arc-shaped rack 18 for transmission. The support rod 1 is internally provided with a storage battery which supplies power to the motor and the winch. Here, the motor drives the transmission wheel 16 to rotate, and the transmission wheel 16 drives the upper blade 9 and the lower blade 10 to rotate reversely by meshing with the upper arc-shaped rack 17 and the lower arc-shaped rack 18, so as to realize the action of cutting the fruit root branches. Specifically, the tooth surface of the upper arc-shaped rack 17 is positioned on the outer convex surface, the tooth surface of the lower arc-shaped rack 18 is positioned on the inner concave surface, and the transmission wheel 16 is positioned in a gap between the outer convex surface of the upper arc-shaped rack 17 and the inner concave surface of the lower arc-shaped rack 18, so that the space occupied by the transmission of the power device can be reduced, and the size of the whole high-altitude fruit picker is further reduced.

One configuration of the buffer net 3 is: the buffer net 3 is woven by a plurality of elastic ropes, that is, two end parts of each elastic rope are respectively connected to the two swing rods 4, and two end parts of all the elastic ropes are positioned on the same horizontal plane, so that the buffer net 3 is in a grid structure. As shown in fig. 6, when the swing link 4 abuts against the vibrating ring 5, the state of the buffer net 3 is the a state, and when the swing link 4 rotates, the state of the buffer net 3 is the B state; after the lower end part of the swing rod 4 swings and extends, the density of the squares on the buffer net 3 is reduced, and the area of each square in the vertical direction is increased, namely the opening of each square is increased, so that the probability that the fruit passes through the squares is increased.

Another structure of the buffer net 3 is: the buffer net 3 is woven by a plurality of elastic ropes, that is, a reinforcing ring 19 is arranged in the middle of a plurality of swing rods 4, the elastic ropes are uniformly distributed around the reinforcing ring 19, one end of each elastic rope is connected with the swing rod 4, the other end of each elastic rope is connected with the reinforcing ring 19, and all the elastic ropes are connected with the swing rods 4 on the same horizontal plane, so that the buffer net 3 is of a circular ring 15-shaped structure. Wherein, the quantity of beaded finish 19 can have two, and the elasticity rope is connected with two beaded finishes 19 in proper order, and the elasticity rope sets up along beaded finish 19 diameter direction. As shown in fig. 7, when the swing link 4 abuts against the vibrating ring 5, the state of the buffer net 3 is a state a, and after the swing link 4 rotates, the lower end of the swing link 4 is unfolded, the state of the buffer net 3 is changed from a to B, the density of the meshes on the buffer net 3 is reduced, and the area of each mesh in the vertical direction is increased, that is, the openings of the meshes are increased, so that the probability that the fruit passes through the meshes is increased.

The upper blade 9 is positioned above the lower blade 10, the upper hook rod 11 is positioned above the upper blade 9, and the lower hook rod 12 is positioned below the lower blade 10, so that the matching of the upper hook rod 11 and the lower hook rod 12 is separated from the matching of the upper blade 9 and the lower blade 10 in space, and the motion interference generated during the two matching operations is avoided.

The upper arc-shaped rack 17 and the upper hook rod 11 are respectively positioned at two ends of the support rod 1, and the lower arc-shaped rack 18 and the lower hook rod 12 are respectively positioned at two ends of the support rod 1.

The working principle is as follows: firstly, an operator holds the support rod 1 by hand, moves the guide ring 2 at the upper end part of the support rod 1 to the position below a fruit to be sheared, moves the guide ring 2 from bottom to top, and then accommodates the fruit bag to be sheared in the guide ring 2, so that a root branch of the fruit to be sheared can be accommodated in an annular structure formed by the upper blade 9, the upper hook rod 11, the lower hook rod 12 and the lower blade 10; the upper blade 9 and the lower blade 10 are driven by the motor to converge to cut fruit root branches, during the initial period of rotation of the upper blade 9 and the lower blade 10, if the fruit root branches are located in the region far away from the support rod 1, the upper hook rod 11 on the upper blade 9 and the lower hook rod 12 on the lower blade 10 can push the fruit root branches to the region close to the support rod 1 for the upper blade 9 and the lower blade 10 to cut, and the fruit root branches can be cut by the upper blade 9 and the lower blade 10 through the pushing of the upper hook rod 11 and the lower hook rod 12;

the cut fruits can fall on the buffer net 3 below the guide ring 2, when the swing rod 4 abuts against the vibrating ring 5, the elastic ropes in the buffer net 3 on the swing rod 4 are in a natural state, or the buffer net 3 is in a relaxed state, so that the fruits can be easily deformed, and when the fruits fall on the buffer net 3 in the state, the buffer net 3 can have a good buffer effect on the fruits; when the winch on the supporting rod 1 pulls the pull rope 7 to contract, the diameter of the plane where the upper end parts of the pull rope 7 are located on the swing rods 4 is reduced, the upper end parts of all the swing rods 4 rotate to gather together at the same time, then the lower end parts of all the swing rods 4 rotate to expand, the diameter of the buffer net 3 connected with the swing rods 4 is expanded, and then the mesh openings on the buffer net 3 are enlarged; in addition, when the opening on the buffering net 3 became bigger, the buffering net 3 can be raised by the rotation of pendulum rod 4 to buffering net 3 can be strikeed with vibrations ring 5 in the in-process that rises, and buffering net 3 can be strikeed by vibrations ring 5 and produce undulantly promptly, and this just can make the fruit that is located on buffering net 3 take place to rock on buffering net 3, and then increases fruit and passes the probability of buffering net 3 upper shed, prevents that fruit from being blocked and can't drop on one of them layer buffering net 3.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the scope of the claims of the present invention should be included in the protection scope of the present invention.
