Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, a grass-jamming prevention mechanism of a hand mower for garden trimming comprises a control block 1, a holding rod 2 is fixedly connected to the top of the control block 1, a rotating shaft 3 is movably connected to the bottom of the control block 1, a blade 4 is fixedly connected to the bottom of the control block 1, a rotating disc 5 is movably connected to one side of the rotating shaft 3 away from the control block 1, a groove 6 is formed in the top of the rotating disc 5, the groove 6 is formed in the top of the rotating disc 5 and is shaped as a circular groove, one end of the blade 4 away from the control block 1 is inserted into the groove 6, a cutter head 7 is movably connected to the outer side of the rotating disc 5, a first gear 8 is fixedly connected to the top of the rotating shaft 3, a loop bar 9 is movably connected to the outer side of the rotating shaft 3, a cross bar 10 is fixedly connected to one side of the loop bar 9 away from the rotating shaft 3, the inside of the gear II 12 is provided with a thread matched with the outside of the screw rod 11, the gear II 12 can only rotate around the screw rod 11 and cannot move up and down, the outside of the gear II 12 is engaged with a gear III 13, the left side of the gear III 13 is fixedly connected with a rotating rod 14, one side of the rotating rod 14, which is far away from the gear III 13, is fixedly connected with a rotating disk 15, the outside of the rotating rod 14 is fixedly connected with a limiting block 16, the internal thread of the limiting block 16 is connected with two screw nails 17, the outside of each screw nail 17 is provided with a thread matched with the inside of the limiting block 16, the right side of each screw nail 17 is movably connected with a control block 1, the right side of the cross rod 10 is fixedly connected with a gear IV 101, the gear IV 8 is engaged with the gear IV 101, the front side of the gear IV 101 is movably connected with a connecting rod 102, the front face of the gear five 103 is movably connected with a connecting rod two 104, the lengths of the connecting rod one 102 and the connecting rod two 104 are the same, one side, away from the gear five 103, of the connecting rod two 104 is movably connected with a gear six 105, a rotating shaft of the gear six 105 is fixedly connected with a rotating shaft of a motor, the outer side of the gear six 105 is meshed with the outer side of the gear five 103, and one side, away from the gear six 105, of the gear five 103 is meshed with a gear four 101.

The working principle is that the screw 17 is rotated clockwise, at the moment, the screw 17 moves towards the direction far away from the control block 1, so that the screw 17 is not connected with the control block 1 any more, the outer side of the screw 17 is provided with a thread matched with the inner part of the limit block 16, the limit block 16 can rotate at the moment, the outer side of the rotating rod 14 is fixedly connected with the limit block 16, the rotating rod 14 can rotate at the moment, the rotating disk 15 is rotated at the moment, the side of the rotating rod 14 far away from the gear wheel III 13 is fixedly connected with the rotating disk 15, the left side of the gear wheel III 13 is fixedly connected with the rotating rod 14, the gear wheel III 13 can rotate at the moment, the outer side of the gear wheel II 12 is engaged and connected with the gear wheel III 13, at the moment, the gear wheel II 12 can rotate, and the inner part of the gear wheel II 12 is provided, unable up-and-down motion, so when two 12 rotations of gear, lead screw 11 can the up-and-down motion, again because the left side fixedly connected with lead screw 11 of horizontal pole 10, so horizontal pole 10 also can move from top to bottom this moment, again because the outside swing joint of axis of rotation 3 has loop bar 9, one side fixedly connected with horizontal pole 10 of axis of rotation 3 is kept away from to loop bar 9, so loop bar 9 can drive axis of rotation 3 up-and-down motion this moment, again because one side swing joint that control block 1 was kept away from to axis of rotation 3 has rolling disc 5, the outside swing joint of rolling disc 5 has tool bit 7, so tool bit 7 can the up-and-down motion this moment, thereby the effect that the tool bit 7 height. Because the gear four 101 is fixedly connected to the right side of the cross rod 10, the gear four 101 will also move along with the cross rod 10 at this time, so that the distance between the gear four 101 and the movement of the rotating shaft 3 is the same, because the gear one 8 is meshed with the gear four 101, and the top of the rotating shaft 3 is fixedly connected with the gear one 8, so that the rotating gear one 8 and the gear four 101 are still in a meshed connection state when the cutter head 7 is adjusted up and down, because the front of the gear four 101 is movably connected with the connecting rod one 102, the side of the connecting rod one 102 away from the gear four 101 is movably connected with the gear five 103, and the side of the gear five 103 away from the gear six 105 is meshed with the gear four 101, so that the gear four 101 will drive the gear five 103 to move while keeping meshed with the gear five 103, and similarly, the gear five 103 and the gear six 105 will also keep meshed with each other, because the rotating shaft of the gear six 105 is fixedly connected with the rotating shaft of the motor, the use of the mower cannot be influenced in the process of lifting the cutter head 7.

Because the bottom fixedly connected with blade 4 of control block 1, so blade 4 can't rotate, because recess 6 has been seted up at the top of rolling disc 5 again, the inside at recess 6 is inserted to the one end that blade 4 kept away from control block 1, so when rolling disc 5 rotated under the drive of axis of rotation 3, blade 4 can cut the plastic bag and the weeds that are close to axis of rotation 3, then make plastic bag and weeds throw away under the effect of centrifugal force to reached debris can not twine the effect of tool bit 7.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
