Technical Field

The invention relates to a tea processing device, in particular to a tea spreading and cooling device.

Background

In the processing process of tea, after the tea leaves are de-enzymed, the tea leaves need to be screened and graded, then the tea leaves are spread out to be volatilized and dried by water vapor, and the subsequent processing procedures can be carried out after the moisture on the fresh tea leaves is removed, so that the spreading and cooling work of the tea leaves is more and more emphasized. Spreading for cooling, namely spreading the picked fresh tea leaves according to a certain thickness, and drying in the sun to make the fresh tea leaves in a wilted state. Generally, tea leaves are put into a spread cooling device for spread cooling, and at present, the spread cooling means is to spread the tea leaves in a spread cooling net and then to stack the spread cooling net on a spread cooling rack, so that the space can be saved when the spread cooling net is placed, and the spread cooling condition can be conveniently checked.

In addition, when the tea leaves are spread on the cooling net, the tea leaves are usually spread on the cooling net manually, and then leveled and homogenized manually. However, the spreading and cooling efficiency is extremely low due to manual spreading and cooling, and the tea leaves are difficult to be uniformly spread and cooled on the spreading and cooling net.

Disclosure of Invention

The invention aims to provide a tea spreading and cooling device, which solves the problem that tea can not be automatically spread and cooled at present and realizes batch tea spreading and cooling.

The tea spreading and cooling device comprises a frame body, a spreading and cooling mechanism arranged above the frame body and a driving mechanism arranged on the frame body; the rack body is transversely provided with a track, the spread cooling mechanism comprises a reciprocating slide seat which is in sliding connection with the track, a hopper is fixed on the reciprocating slide seat through a support frame, the bottom of the hopper is provided with a strip-shaped material port which is arranged along the longitudinal direction, the side wall of the strip-shaped material port is hinged with a baffle through a rotating shaft, the lower part of the baffle is a material blocking part, the upper part of the baffle is a stirring part which extends into the hopper, and the rotating shaft is provided with a torsional spring so that the material blocking part can seal the strip-shaped material port through the torque; convex racks are arranged above the frame body and positioned on two sides of the hopper, convex blocks matched with the convex racks are arranged on two sides of the baffle plate, and the convex blocks are connected with the baffle plate through a one-way mechanism; the driving mechanism drives the reciprocating sliding seat to slide on the rail in a reciprocating mode, when the reciprocating sliding seat slides rightwards, the baffle is in a vibration state and intermittently opens the strip-shaped material opening, and when the reciprocating sliding seat slides leftwards, the baffle seals the strip-shaped material opening; the bottom surface of the reciprocating slide seat is provided with a through groove which is transversely arranged and used for accommodating a cooling net, and a cooling opening which is communicated with the through groove and is opposite to the strip-shaped material opening is formed in the upper part of the reciprocating slide seat.

The technical principle of the scheme is as follows:

placing the spread cooling net in the through groove to enable the spread cooling net to be positioned below the hopper, and driving the reciprocating slide seat to slide rightwards through the driving mechanism; under the effect of one-way mechanism, lug and baffle are in the lock state to under the protruding rack is to the continuous extrusion of lug, the lug will be in the vibration state, thereby the lug drives the baffle vibration with intermittent type nature open the bar material mouth. When the strip-shaped material port is opened, tea leaves in the hopper are discharged through the strip-shaped material port and enter the spread cooling net through the spread cooling port, and the tea leaves can be spread on the spread cooling net due to the fact that the hopper slides rightwards along with the reciprocating sliding seat and the vibration frequency of the baffle is controlled to be fast.

When the driving mechanism drives the reciprocating slide seat to slide leftwards, the lug is separated from the rotating shaft of the baffle under the action of the one-way mechanism; therefore, although the convex teeth extrude the convex block to enable the convex block to vibrate, the convex block cannot drive the baffle to vibrate due to the fact that the convex block is separated from the rotating shaft; namely, in the process that the hopper slides leftwards, the strip-shaped material port is always in a closed state.

The beneficial effect of this scheme lies in:

(1) in the process that the hopper moves rightwards to spread and cool the tea leaves, the strip-shaped material port is in an intermittent opening state; when tea leaves are discharged from the strip-shaped material port and fall on the spreading and cooling net, the tea leaves can diffuse to two sides; in the scheme, the tea intermittently falls on the spreading cooling net, so that the phenomenon that the tea is spread too thickly due to the fact that the tea diffuses towards two sides can be avoided, and the tea is uniformly distributed on the spreading cooling net.

(2) In the vibrating process of the baffle, the baffle can drive the tea to vibrate, so that the tea is in a loose state, and the tea can be prevented from blocking the strip-shaped material opening.

(3) The baffle includes the portion of keeping off the material that distributes according to the upper and lower relation and stirs the portion to all can drive the tealeaves vibration in the top of bar material mouth department and bar material mouth, be favorable to the loose of tealeaves on the one hand, on the other hand also is favorable to tealeaves discharge bar material mouth.

The first preferred scheme is as follows: as a further optimization of the basic scheme, the left end of the reciprocating sliding seat is provided with a leveling plate, the right end of the leveling plate is hinged on the reciprocating sliding seat through a hinged shaft, and the hinged shaft is provided with a torsional spring so that the left end of the leveling plate is downwards inclined and pressed on the rail.

In this preferred scheme, through making the cool net of stand place on the support body and be higher than the track, when reciprocal slide slides right, the cool net of stand will upwards extrude the flattening board to make the flattening board can follow the upper surface process of cool net of stand, in order to put in order the tealeaves on the cool net of stand to level. After the leveling plate crosses the spreading cooling net, the leveling plate is pressed on the rail again under the action of the torsion spring; the reciprocating slide base drives the leveling plate to move leftwards, and the leveling plate cannot cross the spread cooling net due to the blocking of the track to the leveling plate, so that the leveling plate pushes the spread cooling net out.

The preferred scheme II is as follows: as a further optimization of the first preferred scheme, the stirring part consists of a plurality of stirring rods, and the interval between the adjacent stirring rods is 2-3 cm. The stirring part is arranged in a rod shape and provided with intervals, which is more beneficial to stirring the tea leaves.

The preferable scheme is three: as a further optimization to the second preferred scheme, the side of the reciprocating slide is provided with an opening communicated with the through groove, the driving mechanism comprises a stepping motor, the stepping motor drives the reciprocating slide to slide in a reciprocating manner through a slider-crank mechanism, a press switch electrically connected with the stepping motor is arranged on a frame body below the through groove of the reciprocating slide, and the press switch is extruded to stop the operation of the stepping motor.

In the preferred scheme, the side surface of the reciprocating slide seat is provided with an opening, and the spread cooling net can be placed into the through groove below the reciprocating slide seat from the opening. The frame body is provided with a press switch, and when the spread cooling net is pushed out by the leveling plate, the press switch is not extruded any more, so that the stepping motor stops running; after the spread cooling net is placed into the opening, the spread cooling net extrudes the press switch, and the stepping motor continues to operate, so that the device can continuously operate, and the spread cooling efficiency is improved.

The preferable scheme is four: as a further optimization of the preferred scheme three, a cylinder body is fixedly connected to the frame body, and a piston is arranged in the cylinder body; reciprocating slide and piston fixed connection, the bottom of hopper is provided with the tuyere, and bar material mouth and tuyere set up the both sides at the hopper respectively, the cylinder body is through admitting air check valve and outside intercommunication, and the cylinder body is connected with the tuyere through the exhaust check valve.

In the preferred scheme, when the reciprocating slide seat slides back and forth, the piston in the cylinder body is driven to slide back and forth. In the process, the cylinder body sucks air through the air inlet one-way valve and discharges air to the blast port through the air outlet one-way valve; the air is blown into the hopper from the blast port to stir the tea in the hopper, and meanwhile, the movement of the tea to one side of the strip-shaped opening is facilitated.

The preferable scheme is five: as a further optimization of the preferred scheme three, a cylinder body is fixedly connected to the frame body, and a piston is arranged in the cylinder body; the reciprocating slide seat is fixedly connected with the piston, the bottom of the hopper is provided with a blast port, the strip-shaped material port and the blast port are respectively arranged on two sides of the hopper, the cylinder body is communicated with the outside through an air inlet one-way valve, and the cylinder body is connected with the blast port through a pressing valve; the bottom of cylinder body is equipped with the compression chamber, presses the valve setting in the compression intracavity, and the piston extrusion is pressed the valve and then is pressed the valve and switch on.
