Description
Technical Field
[0001] This utility model relates to the technical field of tea production and processing equipment, and in particular to a tea turning machine. Background Technology
[0002] Some dark teas, such as Pu-erh tea and Liubao tea, require fermentation in a pile during processing. When fermentation reaches a certain time or temperature, the tea leaves need to be turned over to prevent localized overheating and subsequent deterioration of quality. Currently, with continuous industrial development, tea turning is shifting from manual to mechanized processes.
[0003] Chinese invention patent (patent application number: 201210303593.X) discloses a tea turning machine, which includes a frame, digging wheels, a conveyor belt, a de-clumping machine, a transverse conveyor, traveling wheels, and steering wheels. The digging wheels are fixed to the front of the frame at both ends via half-shafts. Their cross-section is fan-shaped, with teeth at the top of the blades. Adjacent blades form a U-shaped storage hopper, and the inner wall of the hopper is provided with protruding, pointed round steel bars as long teeth. This invention can mechanically turn fermented Pu-erh tea piles, breaking up tea clumps simultaneously. The turning speed is fast and the operation is simple. However, in practical applications, the rotating digging wheels exert a significant impact on the tea pile, causing tea leaves to splash outside the machine. This is not only difficult to clean but also results in some tea leaves not being turned, thus affecting the quality of the tea. Summary of the Invention

The turning mechanism includes a turning drive, a turning hopper, and multiple turning throwers. The turning hopper is connected to the mounting frame and located below the discharge trough. The turning hopper forms a collection trough and a discharge port communicating with the collection trough. The discharge port is connected to the conveyor belt. The turning drive is installed on the turning hopper. The multiple turning throwers are driven to the turning drive and are spaced apart in the collection trough.
[0006] In an alternative embodiment, the opening of the collection trough is flared outwards from the side facing away from the conveyor belt.

[0009] In an optional embodiment, the throwing rod includes a throwing section of a connecting segment connected to the drive shaft, the throwing section being connected to the end of the connecting segment and extending along the length of the drive shaft.
[0010] In an optional embodiment, the throwing section and the connecting section are integrally formed.

[0022] Reference Figures 1 to 4 This utility model proposes a tea leaf turning machine 1.
[0023] In this embodiment of the utility model, the tea leaf turning machine 1 includes: a frame 100; a moving mechanism installed on the frame 100; and a lifting mechanism 300, including a mounting frame 310, a conveyor belt 320, and a discharge chute 330. The mounting frame 310 is installed on the frame 100, the conveyor belt 320 is installed on the mounting frame 310 and is inclined to the frame 100, and the discharge chute 330 is installed at one end of the conveyor belt 320 and has a connected inlet 330a and a discharge outlet 330b. The inlet 330a is connected to the conveyor belt 320. The pile turning mechanism includes a pile turning drive, a pile turning hopper 420, and multiple pile turning throwers 430. The pile turning hopper 420 is connected to the mounting frame 310 and located below the discharge chute 330. The pile turning hopper 420 forms a collection trough 420a and a discharge port 420b communicating with the collection trough 420a. The discharge port 420b is connected to the conveyor belt 320. The pile turning drive is installed in the pile turning hopper 420. The multiple pile turning throwers 430 are drivenly connected to the pile turning drive and are spaced apart in the collection trough 420a.
[0024] Specifically, the frame 100 can be formed by welding or screwing together metal profiles. The moving mechanism includes four casters 210 and a drive motor. The four casters 210 are spaced apart at the bottom of the frame 100. The drive motor is mounted on the frame 100 and is connected to two or four casters 210 via a linkage shaft. That is, the tea compost turner 1 can be dual-drive or four-drive. The moving mechanism also includes a control lever 220, which is connected to two casters 210 to control the steering of the tea compost turner 1. The specific structure and working principle of the moving mechanism mounted on the frame 100 and driving it to move are relatively mature technologies and will not be described in detail here.
[0025] The mounting frame 310 of the lifting mechanism 300 is also made of metal profile. The mounting frame 310 extends in a long strip shape and has a connecting end (not shown) and an adjusting end (not shown) arranged opposite to each other. The end away from the control lever 220 is the connecting end, which is rotatably connected to the frame 100 via a mounting shaft. The end closer to the control lever 220 is the adjusting end, which is connected to the frame 100 via an angle adjusting member 340. This angle adjusting member 340 can drive the adjusting end to rise and fall relative to the frame 100, so that the mounting frame 310 rotates relative to the frame 100 with the mounting shaft as the fulcrum, thereby adjusting the tilt angle between the mounting frame 310 and the frame 100. The conveyor belt 320 is mounted on the mounting frame 310, and its extension direction is the same as that of the mounting frame 310. The conveyor belt 320 includes a conveyor belt drive motor, multiple conveyor rollers, and a connecting belt. The multiple conveyor rollers are rotatably connected to the mounting frame 310, and the connecting belt is sleeved on the outside of the multiple conveyor rollers. One of the conveyor rollers is connected to the conveyor belt drive motor via two sprockets and a chain. The conveyor belt drive motor drives one of the conveyor rollers to rotate, which in turn drives the connecting belt to rotate, and the connecting belt drives the remaining conveyor rollers to rotate. The discharge chute 330 is a shell-shaped cavity made of sheet metal material, forming a connected inlet 330a and a discharge outlet 330b. The discharge chute 330 is connected to the mounting frame 310 and is located above the turning hopper 420. In this application, the turning mechanism throws the tea leaves through the discharge port 420b onto the connecting belt, which then conveys the tea leaves to the drop trough 330 located above it. The tea leaves enter the drop trough 330 through the inlet 330a and fall back to the ground through the drop port 330b, thus completing the turning of the tea leaves.
[0026] In another embodiment, the lifting mechanism 300 further includes multiple partition plates 350. The multiple partition plates 350 are spaced apart on the surface of the connecting belt by means of adhesive or screw connection. By setting multiple partition plates 350, the tea leaves can be prevented from accumulating on the connecting belt and sliding downward. In this way, the performance of the tea leaf turning machine 1 is more stable.
[0027] Further, in this embodiment, the angle adjustment component 340 includes an angle adjustment drive motor 341, a transmission screw 342, a transmission nut 343, and a connecting rod 344. The angle adjustment drive motor 341 is mounted on the frame 100. The transmission screw 342 is rotatably connected to the frame 100 via a bearing seat. The transmission screw extends horizontally and is connected to the angle adjustment drive motor 341 via a coupling. The transmission nut 343 is connected to the transmission screw 342. The two ends of the connecting rod 344 are rotatably connected to the mounting frame 310 and the transmission nut 343 via connecting shafts, respectively. The angle adjustment drive motor 341 drives the transmission screw 342 to rotate, and the transmission nut 343 reciprocates along the extension direction of the transmission screw 342, thereby driving the connecting rod 344 to move. The connecting rod 344 moves closer to or further away from the turning hopper 420. The mounting frame 310 rotates relative to the frame 100, causing the connecting belt to form different angles with the frame 100. In this application, the structure of the angle adjustment component 340 is relatively simple. By adjusting the angle between the connecting belt and the frame 100, the turning effect is better.
[0028] The turning hopper 420 of the turning mechanism is connected to one side of the mounting frame 310 by screws and is located below the discharge chute 330. The turning hopper 420 forms a collection trough 420a and a discharge port 420b communicating with the collection trough 420a. The discharge port 420b is connected to the lowermost end of the conveyor belt 320. The turning drive component is installed on the turning hopper 420. The turning drive component includes a turning drive motor 411, a drive pulley 412, a driven pulley 413, a conveyor belt, and a drive shaft 414. The drive shaft 414 is rotatably connected to the turning hopper 420 through bearings. The turning drive motor 411 is installed on the turning hopper 420. The drive pulley 412 is sleeved on the output shaft of the turning drive motor 411. The driven pulley 413 is connected to the drive shaft 414. The conveyor belt is sleeved on the outside of the drive pulley 412 and the driven pulley 413. Multiple turning and throwing wheels 430 are connected to the drive shaft 414 of the turning drive and are spaced apart in the collection trough 420a. The turning drive motor 411 drives the drive shaft 414 to rotate, and the turning and throwing wheels 430 rotate in the collection trough 420a, throwing the tea leaves toward the discharge port 420b.
[0029] The working principle of this application is as follows: Driven by the moving mechanism, the frame 100 moves towards the piled tea leaves. As the frame 100 moves, the tea leaves gradually move into the collection trough 420a of the turning hopper 420. The turning drive unit drives multiple turning throwing wheels 430 to rotate within the collection trough 420a, breaking up the tea leaves and throwing them from the discharge port 420b onto the conveyor belt 320. The conveyor belt 320 transports the tea leaves to the drop trough 330 located above the turning hopper 420. The tea leaves enter the drop trough 330 from the inlet 330a and fall back to the ground from the drop port 330b, thus completing the turning of the tea leaves. The tea leaf turning machine 1 in this application not only improves the efficiency of tea leaf turning, but also, because the turning hopper 420 is set up and the operation of the turning throwing wheels 430 throwing the tea leaves onto the conveyor belt 320 is carried out within the collection trough 420a, the splashing of tea leaves during the turning process can be largely avoided. In addition, when the frame 100 is moving, the turning hopper 420 can collect all the tea leaves into the collection trough 420a, which can turn the tea pile over completely and thus improve the quality of the tea.
[0030] Furthermore, in this embodiment, the opening of the collection trough 420a is flared outwards from the side facing away from the conveyor belt 320. This flare can be formed by two inclined guide plates installed at the opening of the collection trough 420a. By setting the opening of the collection trough 420a to a flared shape, the tea leaves can be guided into the collection trough 420a to the maximum extent when the frame 100 moves, and then turned over by the turning mechanism. This makes the tea turning machine 1 more efficient.
[0031] In this application, the specific structure of the turning and throwing wheel 430 includes multiple throwing rods 431, each with a throwing section 3412 including a connecting section 4311. The connecting section 4311 is connected to the drive shaft 414 by welding or screws. The multiple connecting sections 4311 are arranged at intervals along the circumference of the drive shaft 414. The throwing section 3412 is connected to the end of the connecting section 4311 and extends along the length of the drive shaft 414, that is, the overall extension trajectory of the throwing rod 431 is a figure-7 shape. The connection between the throwing section 3412 and the connecting section 4311 can be formed by welding two metal rods or by bending them into one piece. In this embodiment, the throwing section 3412 and the connecting section 4311 are integrally formed, thus the overall strength of the throwing rod 431 is higher. This application uses multiple throwing rods 431 spaced circumferentially along the drive shaft 414. Its structure is relatively simple and easy to install. The "7"-shaped throwing rods 431 can disperse the tea leaves when rotating and simultaneously throw them toward the discharge port 420b.
[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
