DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1

[0033] like Figure 1 and Figure 2 As shown, a mechanical device for picking tea leaves comprises a box body 1. When the device is used, two bags need to be fixed on the box body 1 to facilitate the collection of tea leaves. A screening mechanism 2 for screening tea leaves is provided in the inner cavity of the box body 1. During the picking process, the sizes of the picked tea leaves are different. In the subsequent processing, the leaves and leaf buds in the tea leaves need to be processed separately, and the prices of the two are also different. Generally, the volume of the leaf buds is significantly smaller than that of the leaves. Separating the two during picking not only facilitates the transportation of the tea leaves, but also facilitates the subsequent processing work. The tea leaves can be directly processed in different ways without screening during processing.

[0034] Then, in response to different picking conditions, the screening mechanism 2 can be adjusted. By controlling the screening speed of the screening mechanism 2, the tea leaves can be screened better when there are more leaf buds, thereby ensuring the screening effect of the device. A feeding mechanism 3 for controlling the feeding amount of tea leaves is provided on the upper side of the screening mechanism 2. When the screening speed of the screening mechanism 2 is reduced, it takes a certain amount of time to discharge the tea leaves in the box 1. In order to prevent the device from being blocked during the screening process, the feeding amount of the feeding mechanism 3 can be controlled to ensure that the device can be used normally, thereby ensuring the screening effect of the device.

[0035] Then, a connecting component 4 for feeding is provided on the upper side of the box body 1, and a picking mechanism 5 for picking tea leaves is provided on the front side of the connecting component 4. The device can be disassembled, and the screening mechanism 2 and the unloading mechanism 3 in the box body 1 screen the tea leaves, and the picking mechanism 5 picks the tea leaves. The tea leaves picked by the picking mechanism 5 need to be transported to the box body 1 through the connecting component 4, and the screening mechanism 2 performs the screening work. By disassembling, the device can be made lighter and convenient to transport.

[0036] It should be noted that the picking mechanism 5 can also be used to prune the tea trees. The pruned branches and leaves do not need to be collected, and there is no need to use the screening mechanism 2 for screening, so that the device can be used flexibly.

[0037] Further explanation, in order to be able to screen the tea leaves, such as Figure 3 and Figure 4 As shown, the screening mechanism 2 includes a threaded rod 21, and a threaded block 22 is threadedly connected on the surface of the threaded rod 21. The threaded block 22 can be driven to move up and down by rotating the threaded rod 21. A screening box 23 is fixedly installed in the inner cavity of the box body 1. The screened leaf buds will fall into the screening box 23, and then fall downward through the arc-shaped inner wall of the screening box 23, and finally be collected. A vibration motor 24 is provided in the screening box 23. The vibration motor 24 is connected to the threaded block 22. The vibration motor 24 is required to provide power for the screening work, and the threaded block 22 can drive the vibration motor 24 to move;

[0038] Then, a screening plate 25 is rotatably installed at the output end of the vibration motor 24. The screening plate 25 can block the larger leaves, and the smaller leaf buds will fall into the screening box 23. The vibration motor 24 drives the screening plate 25 to shake, which can speed up the screening speed of the device and increase the screening effect of the device. The screening plate 25 is rotatably installed in the inner cavity of the screening box 23. When the threaded block 22 drives the vibration motor 24 to move, the vibration motor 24 will push the screening plate 25 to rotate. A connecting rod 26 is fixedly installed in the middle of the upper end of the screening plate 25, and the connecting rod 26 will also move with the screening plate 25.

[0039] Specifically, the threaded rod 21 is manually rotated to drive the threaded block 22 and the vibration motor 24 to move upward. During the upward movement, the vibration motor 24 will push the screening plate 25 and the connecting rod 26 to move simultaneously, and the moving screening plate 25 will rotate to change its own inclination.

[0040] It should be noted that the smaller the inclination angle of the screening plate 25, the slower the sliding speed of the tea leaves on the screening plate 25, the longer the screening time will be, so that the device can fully screen the tea leaves. In order to prevent blockage, it is necessary to adjust the feeding speed of the feeding mechanism 3 through the connecting rod 26.

[0041] Further explanation, in order to spread the tea leaves evenly on the upper end of the screening plate 25, as Figure 5 As shown, the unloading mechanism 3 includes an arc-shaped plate 31. The picked tea leaves will be piled on the upper end of the arc-shaped plate 31. A plurality of feed holes 32 are provided on the upper end of the arc-shaped plate 31. The tea leaves on the arc-shaped plate 31 will slide down from the feed holes 32, and then unloading will be performed. An adjusting component 33 is provided in the inner cavity of the plurality of feed holes 32. The adjusting component 33 can adjust the inner diameter. The smaller the inner diameter, the slower the unloading speed. When the screening plate 25 is slowly screening, there will be no blockage. A plurality of discharge holes 34 are provided on the arc-shaped surface of the arc-shaped plate 31. The feed holes 32 are connected with the discharge holes 34. After the tea leaves in the feed holes 32 pass through the adjusting component 33, they will fall down from the discharge holes 34.

[0042] Then, the discharge holes 34 opened in the array can distribute the tea leaves on the screening plate 25, and the tea leaves will not be piled up on the screening plate 25, so that the screening plate 25 can perform the screening work better. A bottom plate 35 is provided on the lower side of the arc disk 31. The bottom plate 35 plays a supporting role and will not affect the unloading process of the discharge hole 34. The bottom plate 35 is connected to the connecting rod 26. When the connecting rod 26 moves up and down, it can push the bottom plate 35 to move up and down. A plurality of racks 36 are fixedly installed on the upper end of the bottom plate 35, and the racks 36 will move up and down with the bottom plate 35.

[0043] It should be noted that the connection relationship between the connecting rod 26 and the bottom plate 35 is a rotational connection. When the connecting rod 26 moves with the screening plate 25, there will be a rotational offset and it will not go straight up or down. Through the rotational connection, the connecting rod 26 can push the bottom plate 35 to move up and down without any offset.

[0044] Further explanation, in order to control the feeding speed of the feed hole 32 and the discharge hole 34, as shown in FIG. Figure 6 As shown, the adjustment assembly 33 includes two support plates 331, the support plates 331 are fixedly installed in the inner cavity of the feed hole 32, a hollow gear 332 is rotatably installed between the two support plates 331, and a plurality of racks 36 are respectively meshed with the plurality of hollow gears 332. When the racks 36 move up and down, the hollow gears 332 can be driven to rotate, and a plurality of tooth blocks 333 are fixedly installed on the end surface of the hollow gear 332, and the tooth blocks 333 will rotate with the hollow gear 332;

[0045] Then, a number of baffle plates 334 are rotatably installed between the two support plates 331, and a number of tooth blocks 333 are respectively engaged with the number of baffle plates 334. When the baffle plates 334 rotate in the direction away from each other, their diameters will become larger and larger. When the rack 36 moves upward, it will drive the hollow gear 332 and the tooth block 333 to rotate clockwise, and the three baffle plates 334 will move in the direction away from each other.

[0046] Further explanation, in order to pick the tea leaves, Figure 7 As shown, the picking mechanism 5 includes a shell 51, an air inlet pipe 52 is fixedly installed on the upper side of the front end of the shell 51, and a plurality of air outlet pipes 53 are fixedly installed on the arc surface of the air inlet pipe 52, and the plurality of air outlet pipes 53 are all connected with the air inlet pipe 52. A small blower can be used to introduce air into the air inlet pipe 52, and then the air flows into the shell 51 through the air outlet pipe 53, so that the picked tea leaves can be blown into the shell 51, so that the tea leaves can be collected conveniently;

[0047] Then, two cutting saws 54 are provided in the inner cavity of the shell 51. The cutting saw 54 located at the lower side is fixedly installed in the inner cavity of the lower side of the shell 51, and the cutting saw 54 located at the upper side is slidably installed in the inner cavity of the shell 51. By moving the cutting saw 54 located at the upper side left and right and cooperating with the cutting saw 54 located at the lower side, the tea leaves in contact can be picked. An inclined panel 55 is fixedly installed on the inner wall of the lower side of the shell 51. When the air outlet pipe 53 blows the tea leaves, it will roll to the upper end of the inclined panel 55, and then enter the box 1 through the connecting component 4 for screening.

[0048] It should be noted that in order to make the cutting saw 54 move back and forth to pick the tea leaves on the tea tree, air needs to be blown into the air inlet pipe 52 through a blower, and the air in the air inlet pipe 52 is then discharged from the air outlet pipe 53. The flowing air will push the tea leaves in the shell 51 to float to the upper end of the inclined panel 55.

[0049] The specific implementation of this embodiment is as follows: manually rotate the threaded rod 21 to drive the threaded block 22 and the vibration motor 24 to move upward. During the upward movement of the vibration motor 24, the screening plate 25 and the connecting rod 26 will be pushed to move simultaneously. The moving screening plate 25 will rotate to change its own inclination. When the connecting rod 26 moves upward, it will push the bottom plate 35 to move vertically upward. After the screening plate 25 moves to a suitable position, it will maintain a certain angle, thus completing the adjustment of the screening speed.

[0050] During adjustment, the bottom plate 35 will push the racks 36 to move upwards. Under meshing action, the racks 36 will drive the hollow gear 332 to rotate clockwise, and the tooth blocks 333 will rotate along with the hollow gear 332, which will cause the baffle plates 334 to move away from each other, and the diameters between them will become larger. With the inclined bottom plate 35, the screening work can be carried out faster, while ensuring the screening effect, the device will not be blocked.

[0051] Then the cutting saw 54 can be moved back and forth to pick the tea leaves on the tea tree. Air needs to be blown into the air inlet pipe 52 through the blower, and the air in the air inlet pipe 52 is discharged from the air outlet pipe 53. The flowing air will push the tea leaves in the shell 51 to float to the upper end of the inclined plate 55, and then enter the upper end of the arc plate 31 through the connecting component 4. The tea leaves accumulated on the arc plate 31 will fall into the feeding hole 32, and then the feeding speed is controlled by the adjusting component 33.

[0052] Finally, the picked tea leaves fall downward from the discharge hole 34, so that they can be scattered and fall to the upper end of the bottom plate 35, and then the vibration motor 24 is started to drive the screening plate 25 to vibrate, and the screening plate 25 can screen the tea leaves on the screening plate 25, and the leaf buds with smaller volume will fall into the screening box 23, and then the leaves and leaf buds can be collected separately.

[0053] Embodiment 2

[0054] This embodiment is a further improvement on the connection assembly 4 based on the first embodiment, so that the device can more conveniently connect the picking mechanism 5 and the box body 1, so as to achieve the purpose of picking tea leaves and screening them at the same time.

[0055] Further explanation, in order to be able to transport the picked tea leaves into the box 1, as Figure 8 As shown, the connecting component 4 includes a feed pipe 41, a plurality of slots are provided at the front end of the feed pipe 41, adsorption components 43 are fixedly installed in the plurality of slots, a feed pipe 42 is provided on the front side of the feed pipe 41, the feed pipe 41 is connected with the box body 1, the feed pipe 42 is connected with the shell body 51, the feed pipe 41 and the feed pipe 42 form a pipeline to transport the tea leaves in the shell body 51 into the box body 1, and the feed pipe 41 and the feed pipe 2 42 are connected by the adsorption component 43, and a strong suction force is not required, and the feed pipe 41 and the feed pipe 2 42 only need to fit completely, and the weight of the tea leaves themselves is relatively small, and the feed pipe 41 and the feed pipe 2 42 will not be disconnected due to the weight.

[0056] Further explanation, in order to facilitate the adsorption of the feed pipe 1 41 and the feed pipe 2 42, as shown in FIG. Fig. 9 As shown, the adsorption assembly 43 includes a fixed tube 431, and a movable tube 432 is slidably installed in the inner cavity of the fixed tube 431. A plurality of circular holes are opened on the arc surface of the movable tube 432. When adsorption is performed, the movable tube 432 needs to be moved into the fixed tube 431, and the air therein is discharged through the circular holes, and the adsorption function is realized by air pressure. A bevel tube 433 is fixedly installed at the lower end of the movable tube 432, and the diameter of the bevel tube 433 is larger than that of the movable tube 432. When the work is completed and needs to be disassembled, the air can be sucked in through the bevel tube 433 to keep the internal and external pressures the same, and there will be no adsorption effect.

[0057] Then, a suction cup 434 is fixedly installed at the lower end of the inclined tube 433. The suction cup 434 is made of a relatively soft plastic material. When the air in the suction cup 434 is small, a certain adsorption effect will be generated, which can meet the needs of the device. An elastic spring 435 is fixedly installed in the inner cavity of the movable tube 432, and a piston tube 436 is fixedly installed in the inner cavity of the fixed tube 431. When the piston tube 436 moves downward, it will push the air in the movable tube 432 and the suction cup 434 to be discharged from the circular hole. The elastic spring 435 and the piston tube 436 are connected to each other.

[0058] Specifically, the suction cup 434 and the movable tube 432 are squeezed to move toward the inside of the fixed tube 431. During the movement, the piston tube 436 pushes the air to flow outward from the circular hole. When the piston tube 436 moves to the lower side of the circular hole, the suction cup 434 will adsorb the feed tube 42.

[0059] The specific implementation of this embodiment is as follows: when picking is required, the feed tube 1 41 and the feed tube 2 42 need to be overlapped together, and then the suction cup 434 and the movable tube 432 are squeezed to move them toward the inside of the fixed tube 431. During the movement, the piston tube 436 pushes the air in the movable tube 432 and the suction cup 434 to flow outward from the circular hole. When the piston tube 436 moves to the lower side of the circular hole, the suction cup 434 will absorb the feed tube 2 42. When the piston tube 436 moves, it will also squeeze the elastic spring 435 to make it contract.

[0060] After the device is used up, it is only necessary to continue squeezing the suction cup 434 so that it pushes the movable tube 432 to move into the fixed tube 431, and the piston tube 436 will move into the inclined tube 433, making it impossible for the suction cup 434 to remain sealed. The outside air can pass through the circular hole and the gap of the inclined tube 433 and enter the suction cup 434, and the feed tube 42 cannot be adsorbed.

[0061] It should be noted that the specific installation method, circuit connection method and control method of the vibration motor 24 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0062] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
