[0004] This patent realizes the uniform heating of tea by vibrating the placement plate. However, since the position where the hot air blows to the placement plate is fixed, and the vibration of the placement plate cannot effectively adjust the horizontal position of the tea, the tea at the position directly blown by the hot air on the placement plate has a good heating effect, while the heating effect of other positions is poor. Therefore, the uniformity of tea withering is reduced. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further elaborates on the present invention in detail with reference to the accompanying drawings.

[0022] Embodiment:

[0023] Refer to Figures 1 to 3, A compound withering device for tea production disclosed by the present utility model includes a base 1 with an open top. A hot air blower 2 is fixedly connected to the inner bottom wall of the base 1. A reciprocating lead screw 3 is horizontally rotatably connected inside the base 1. A motor 4 is fixedly connected to one side of the base 1. The output end of the motor 4 is in transmission connection with the reciprocating lead screw 3. A sliding bar 5 is threadedly connected to the outer peripheral surface of the reciprocating lead screw 3. Both ends of the sliding bar 5 are in contact with the inner wall of the base 1. A circulation shell 6 is fixedly connected to the top of the sliding bar 5. A plurality of spray nozzles 7 are fixedly penetrated through the top of the circulation shell 6. The output end of the hot air blower 2 is connected to the circulation shell 6 through a hose. A plurality of springs 8 are fixedly connected to the top surface of the base 1. The top ends of the plurality of springs 8 are jointly fixedly connected to a hollow placement plate 9.

[0024] In this embodiment, both ends of the sliding bar 5 are in contact with the inner wall of the base 1, so the sliding bar 5 will not rotate with the reciprocating lead screw 3. The spray nozzles 7 are communicated with the circulation shell 6. When the hot air blower 2 works, hot air is conveyed into the circulation shell 6. The hot air moves upward through the spray nozzles 7, passes through the placement plate 9 and contacts the tea leaves, thereby withering the tea leaves.

[0025] When the motor 4 works, it drives the reciprocating lead screw 3 to rotate. The reciprocating lead screw 3 drives the sliding bar 5 to move horizontally back and forth. The sliding bar 5 drives the circulation shell 6 and the spray nozzles 7 to move horizontally back and forth, thereby constantly changing the position of the hot air blowing, so that the tea leaves on the placement plate 9 can all be directly blown by the hot air, and the blowing time intervals are uniform, thus improving the withering heat receiving effect of the tea leaves. Since the output end of the hot air blower 2 is connected with a hose, which can be bent and deformed by stretching, the output end of the hot air blower 2 will not hinder the horizontal movement of the circulation shell 6.

[0026] In a further preferred embodiment of the present utility model, as Figure 2 shown, two cams 10 are fixedly sleeved on the outer peripheral surface of the reciprocating lead screw 3. A first plate 11 is provided between the base 1 and one of the cams 10. A second plate 12 is fixedly connected to the bottom of the base 1 directly above the other cam 10. The bottom surfaces of the first plate 11 and the second plate 12 are coplanar.

[0027] In this embodiment, when the reciprocating lead screw 3 rotates, it drives the two cams 10 to rotate. The cams 10 intermittently contact the first plate 11 and the second plate 12 during rotation, thereby driving the placement plate 9 to vibrate in the vertical direction, making the tea leaves on the placement plate 9 evenly laid and moving in the vertical direction, further improving the heat uniformity of the tea leaves.

[0028] In a further preferred embodiment of the present utility model, as Figure 1 shown, a retaining frame 13 is fixedly connected to the top edge of the placement plate 9.

[0029] In this embodiment, the retaining frame 13 is used to prevent the tea leaves on the placement plate 9 from leaving the placement plate 9 during vibration.

[0030] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 3 shown, one side of the retaining frame 13 close to the first plate 11 is open, and a baffle 14 is hinged to one side of the placing plate 9 close to the first plate 11. The baffle 14 is attached to the open side of the retaining frame 13 and shields the opening of the retaining frame 13. A vertical plate 15 is fixedly connected to the bottom of the baffle 14, and an adjusting portion 16 is provided below the placing plate 9.

[0031] The adjusting portion 16 includes two bottom plates 161 fixedly connected to the bottom of the placing plate 9. One side of the bottom plate 161 is rotatably connected to a screw 162. The screw 162 is in threaded connection with the first plate 11. Two avoiding openings 163 are formed in the side wall of the vertical plate 15. The screw 162 passes through the corresponding avoiding openings 163. Two connecting rods 164 are hinged to one side of the vertical plate 15. The end of the connecting rod 164 away from the vertical plate 15 is hinged to the lower half of the side wall of the first plate 11.

[0032] In this embodiment, the spring 8 can undergo appropriate bending deformation. During the tea withering operation (as Figure 1 shown), the baffle 14 shields the opening of the retaining frame 13 to prevent the tea leaves from falling off the placing plate 9, and the placing plate 9 is in a horizontal state. When the tea withering is completed, the staff rotates the two screws 162 simultaneously, driving the first plate 11 to move towards the bottom plate 161. The first plate 11 is no longer directly above the corresponding cam 10. Therefore, the cam 10 will no longer contact the first plate 11 when rotating. While the first plate 11 is moving, it drives the connecting rod 164 to move. The connecting rod 164 drives the vertical plate 15 to rotate. The vertical plate 15 drives the baffle 14 to rotate, and the baffle 14 no longer shields the opening of the retaining frame 13.

[0033] At this time, the motor 4 works to drive the cam 10 to rotate. The cam 10 contacts the second plate 12 and drives the second plate 12 to move upward. Therefore, the side of the placing plate 9 away from the baffle 14 vibrates intermittently, and the tea leaves on the placing plate 9 automatically fall from the baffle 14. The staff only needs to place a collection box below the baffle 14 to automatically collect the withered tea leaves, which is convenient for the staff to use.

[0034] During the rotation of the vertical plate 15, the screw 162 will not contact the inner wall of the avoiding opening 163. Therefore, the screw 162 will not hinder the movement of the vertical plate 15.

[0035] In a further preferred embodiment of the present utility model, as Figure 2 shown, the top surface of the first plate 11 is in contact with the bottom surface of the placing plate 9.

[0036] In this embodiment, the first plate 11 is in contact with the bottom surface of the placing plate 9, preventing the screw 162 from being bent when the first plate 11 is impacted by the cam 10, and improving the service life of the device.

[0037] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
