Description

Technical Field

[0001] This utility model relates to the field of tea production technology, specifically a device for evenly turning over tea leaves during the withering process. Background Technology

[0002] The purpose of spreading tea leaves out to dry is to control the rate of water loss from fresh leaves (15%-25% moisture content), promote the activity of polyphenol oxidase, and lay the foundation for the "freshness" of green tea and the "floral aroma" of oolong tea.

[0003] A search revealed a utility model patent with Chinese patent publication number CN215224445U, which discloses a tea-spreading device. The device includes a movable base, several spreading trays evenly spaced above the movable base, an annular surrounding plate fixedly connected to the upper surface of the spreading trays, and columns arranged in a circular array fixedly connected to the outer side wall of the spreading trays. The lower end of the columns is fixedly connected to the movable base, a rotating rod movably passes through the middle of the spreading trays, and the lower end of the rotating rod is movably connected to a bracket fixedly connected to the movable base. A motor is installed on the movable base.

[0004] The aforementioned device achieves the purpose of turning the tea leaves by stirring them inside the spreading frame with a turning rod. However, its position is fixed. After rotating too many times, circular gaps will be created in the tea leaves. The turning rod will only move along the fixed gaps, which will greatly reduce the turning effect. Furthermore, the turning rod can only move horizontally and lacks an upward stirring effect. The overlapping parts of the tea leaves cannot be effectively separated, which will also reduce the spreading effect. There is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a device for evenly turning over tea leaves during the spreading process, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tea leaf spreading and turning device, comprising a base plate, a turning assembly installed inside the base plate, the turning assembly comprising two guide rods fixedly connected inside the base plate, both guide rods being horizontally arranged, the two guide rods being slidably fitted onto the same movable seat, a bevel gear being rotatably connected to the outer wall of one end of the movable seat, a striking rod being rotatably connected inside the movable seat, and a horizontally arranged rod being arranged outside the striking rod, a bevel gear being coaxially fixed to one end of the striking rod, the bevel gear meshing with the bevel gear, a horizontally arranged transmission rod being rotatably connected inside the base plate, and the bevel gear being slidably fitted onto the outside of the transmission rod.

[0007] As a further preferred embodiment of this technical solution, a horizontally arranged lead screw is rotatably connected inside the base plate. The lead screw is threadedly connected inside the movable seat. A motor is fixedly installed on one outer wall of the base plate. The output end of the motor is coaxially fixed with one end of the lead screw. A sprocket is coaxially fixed to both the transmission rod and one end of the lead screw. The two sprockets are fitted with the same chain.

[0008] It can turn the tea leaves over completely, ensuring that some leaves are not turned over, which helps to guarantee the withering effect of the tea leaves. Start the motor on the outside of the base plate. The motor drives the lead screw to start rotating. The lead screw drives the moving seat to move along the two guide rods. The lead screw drives the transmission rod to rotate through two sprockets and a chain. The transmission rod drives the bevel gear to rotate. The bevel gear drives the second bevel gear to rotate through meshing. The second bevel gear drives the striking rod to rotate. When the protruding part of the striking rod strikes the bottom wall of the taut receiving net, the tea leaves inside will be moved upward and spread out, thus completing one turning. The tea leaves in the receiving net will be evenly spread out.

[0009] As a further preferred embodiment of this technical solution, a receiving component is installed inside the base plate. The receiving component includes two support frames placed inside the base plate, and the two support frames are arranged symmetrically. A connecting frame is fixedly installed on the outer wall of the side of the two support frames that are close to each other. The same receiving net is fixedly connected between the two connecting frames, and the receiving net is located at the top of the striking rod.

[0010] As a further preferred embodiment of this technical solution, a horizontally arranged bidirectional lead screw is rotatably connected inside the base plate, and two support frames are respectively threaded onto the threads at both ends of the bidirectional lead screw.

A motor is fixedly installed on one side of the outer wall of the base plate, and the output end of the motor is coaxially fixed with one end of the bidirectional lead screw.

[0011] After completing the work, start the second motor on the outside of the base plate. The second motor drives the double-sided lead screw to start rotating. The rotating double-sided lead screw drives the two support frames to move closer to each other along the two guide rods. The taut receiving net bag becomes loose, and the tea leaves will automatically slide into the middle of the receiving net bag. Simply flip the receiving net bag to achieve quick discharge. The operation is convenient enough.

[0012] As a further preferred embodiment of this technical solution, a baffle is fixedly connected to the bottom of the outer wall of each of the two support frames that are close to each other, and the two baffles are arranged to overlap each other.

[0013] As a further preferred embodiment of this technical solution, the receiving net is made entirely of spandex material.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 , Figure 3 and Figure 4 As shown in this embodiment, a tea leaf spreading and turning device includes a base plate 1. A turning assembly 3 is installed inside the base plate 1. The turning assembly 3 includes two guide rods 302 fixedly connected inside the base plate 1. Both guide rods 302 are horizontally arranged. The two guide rods 302 are slidably sleeved on the same movable seat 303. A bevel gear 307 is rotatably connected to the outer wall of one end of the movable seat 303. A striking rod 305 is rotatably connected inside the movable seat 303. A horizontally arranged rod is arranged outside the striking rod 305. A bevel gear 308 is coaxially fixed to one end of the striking rod 305. The bevel gear 307 meshes with the bevel gear 308. A horizontally arranged transmission rod 306 is rotatably connected inside the base plate 1. The bevel gear 307 is slidably sleeved on the outside of the transmission rod 306.

[0025] A horizontally arranged lead screw 301 is rotatably connected inside the base plate 1. The lead screw 301 is threaded into the moving seat 303. A motor 304 is fixedly installed on one side of the outer wall of the base plate 1. The output end of the motor 304 is coaxially fixed with one end of the lead screw 301. A sprocket 309 is coaxially fixed to one end of the transmission rod 306 and the lead screw 301. The two sprockets 309 are fitted with the same chain 310.

[0026] The motor 304 on the outside of the base plate 1 is started. The motor 304 drives the lead screw 301 to start rotating. The lead screw 301 then drives the moving seat 303 to move along the two guide rods 302. The lead screw 301 drives the transmission rod 306 to rotate through the two sprockets 309 and the chain 310. The transmission rod 306 drives the bevel gear 307 to rotate. The bevel gear 307 drives the second bevel gear 308 to rotate through meshing. The second bevel gear 308 drives the striking rod 305 to rotate. When the protruding part of the striking rod 305 hits the bottom wall of the taut receiving net bag 405, the tea leaves inside will be hit and moved upward and scattered, thus completing one flipping. The tea leaves in the receiving net bag 405 will be evenly shaken apart.

[0027] like Figure 1 and Figure 2As shown, a receiving component 4 is installed inside the base plate 1. The receiving component 4 includes two support frames 403 placed inside the base plate 1, and the two support frames 403 are arranged symmetrically. A connecting frame 404 is fixedly installed on the outer wall of the side of the two support frames 403 that are close to each other. The same receiving net bag 405 is fixedly connected between the two connecting frames 404. The receiving net bag 405 is located at the top of the striking rod 305.

[0028] A horizontally arranged bidirectional lead screw 401 is rotatably connected inside the base plate 1. Two support frames 403 are threaded onto the threads at both ends of the bidirectional lead screw 401. Two guide rods 402 are fixedly connected inside the base plate 1. The two support frames 403 are slidably sleeved on the outside of the two guide rods 402. A motor 406 is fixedly installed on one side of the outer wall of the base plate 1. The output end of the motor 406 is coaxially fixed with one end of the bidirectional lead screw 401.

[0029] After completing the work, start the motor 406 on the outside of the base plate 1. The motor 406 drives the bidirectional lead screw 401 to start rotating. The rotating bidirectional lead screw 401 drives the two support frames 403 to move closer to each other along the two guide rods 402. The taut receiving net bag 405 becomes loose, and the tea leaves will automatically slide into the middle position of the receiving net bag 405. Simply flip the receiving net bag 405 to achieve quick discharge. The operation is convenient enough.

[0030] like Figure 1 and Figure 2 As shown, a baffle 2 is fixedly connected to the bottom of the outer wall of each of the two support frames 403 that are close to each other, and the two baffles 2 are stacked on each other to prevent tea leaves from falling outside the lead screw 301.

[0031] like Figure 1 and Figure 2 As shown, the receiving net 405 is made entirely of spandex material. Spandex is a highly elastic synthetic fiber that can undergo large deformation under very small stress and has excellent resilience, allowing the receiving net 405 to withstand the compression of the striking rod 305.

[0032] like Figure 3 As shown, the end of the outer rod of the striking rod 305 is cylindrical to prevent it from scratching the receiving net bag 405.

[0033] This utility model provides a device for evenly turning over tea leaves during the withering process. The specific working principle is as follows:

[0034] When the device is in operation, the tea leaves are laid flat on the bottom of the receiving net bag 405. The motor 304 on the outside of the base plate 1 is started. The motor 304 drives the lead screw 301 to rotate, which in turn drives the movable seat 303 to move along the two guide rods 302. The lead screw 301 drives the transmission rod 306 to rotate via two sprockets 309 and a chain 310. The transmission rod 306 drives the bevel gear 307 to rotate, which in turn drives the bevel gear 308 to rotate. The bevel gear 308 drives the striking rod 305 to rotate. When the protruding part of the striking rod 305 strikes the taut bottom wall of the receiving net bag 405, the tea leaves inside are struck and moved upwards and scattered, thus completing one turning. The tea leaves in the receiving net bag 405 are then... The tea leaves are evenly shaken apart. As the striking rod 305 strikes the receiving net 405 during rotation, the tea leaves are subjected to a force that causes them to move horizontally, thus moving a short distance. However, when the striking rod 305 moves in the opposite direction, the tea leaves can roughly return to their original position. Therefore, it is sufficient to leave a certain amount of blank space on both sides of the receiving net 405. After the work is completed, the second motor 406 on the outside of the base plate 1 is started. The second motor 406 drives the bidirectional lead screw 401 to start rotating. The rotating bidirectional lead screw 401 drives the two support frames 403 to move closer to each other along the two guide rods 402. The taut receiving net 405 becomes loose, and the tea leaves will automatically slide into the middle position of the receiving net 405. Simply flipping the receiving net 405 can achieve rapid discharge, making the operation convenient enough.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
