Detailed Implementation
[0022] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.
[0023] See Figure 1-6 As shown, this utility model discloses an automatic tea harvesting machine for Liubao tea, comprising a main frame 1 and a mounting frame 5, connected by a support frame 4. The main frame 1 has moving tracks 6 on both sides of its bottom. A first drive assembly 2 drives the moving tracks 6 on the main frame 1. A blade holder 7 is mounted on the mounting frame 5, with a blade rod 8 slidably mounted on the blade holder 7. Multiple moving blades 9 are mounted on the blade rod 8. A crank-connecting rod mechanism 3 drives the blade rod 8. A pressing device for pressing down tea seedlings is mounted on the mounting frame 5 above the moving blades 9. A belt conveyor 11 for transporting tea leaves is mounted on the support frame 4. A first motor 22 drives a belt drive mechanism, which in turn drives a drive wheel 21 to rotate. The drive wheel 21 engages with the moving tracks to achieve the walking function. The forward and reverse rotation of the first motor 22 enables the tea harvester to move forward and backward, achieving stable movement on the planting area and accelerating harvesting efficiency. As the harvester moves forward, the third motor 16 drives the rotating shaft 15 to rotate via a sprocket and chain transmission mechanism. The rotating shaft 15 drives multiple pressing rods 14 to rotate, which in turn press down the tea leaves, making it easier for the moving blade 9 to cut them. At the same time, the second motor 32 drives the eccentric wheel 33, which in turn drives the connecting rod 34. The connecting rod pushes the connecting block 35, which in turn drives the blade bar 8 to perform a reciprocating linear motion. This allows the moving blade 9 mounted on the blade bar 8 and the blade protector 10 to work together to cut the tea leaves. The harvested tea leaves fall onto the belt conveyor 11 and are transported into the collection box 12 for storage. The entire harvesting process is automated, with a high degree of automation, effectively improving harvesting efficiency. Furthermore, the use of a scissor-type structure for harvesting greatly reduces damage to the tea leaves. The overall structure is simple, easy to manufacture, and has low production costs, making it suitable for large-scale promotion.
[0024] Specifically, each moving blade 9 is equipped with a blade guard 10 on both sides. The blade guard 10 is connected to the bottom of the blade holder 7. The moving blade 9 is movably inserted into the blade guard 10. When the moving blade 9 moves, it can quickly pick tea leaves in conjunction with the blade guard 10, effectively improving picking efficiency.
[0025] Preferably, a collection box 12 is provided on the upper part of the main frame 1, and the belt conveyor 11 is arranged at an angle. The lowest end of the belt conveyor 11 is close to the knife holder 7, and the highest end of the belt conveyor 11 is located above the collection box 12. The belt conveyor 11 can be used to transport the picked tea leaves to the collection box 12 for storage, thereby improving the level of automation.
[0026] Furthermore, the first drive assembly 2 includes a first motor 22, a drive wheel 21, a driven wheel 24, and multiple small wheels 23. The drive wheel 21, driven wheel 24, and small wheels 23 are all rotatably mounted on the main frame 1. The movable track 6 is fitted onto the drive wheel 21, driven wheel 24, and small wheels 23. The first motor 22 is mounted on the main frame 1. The output end of the first motor 22 is connected to the drive wheel 21 through a belt drive mechanism. The first motor 22 drives the drive wheel 21 through the belt drive mechanism. The drive wheel 21 engages with the movable track to achieve the walking function. The small wheels 23 play an auxiliary support role, making the operation more stable. The belt drive mechanism includes a belt and two pulleys. The two pulleys are mounted on the drive wheel 21 and the output end of the first motor 22, and the belt is fitted onto the two pulleys.
[0027] Furthermore, the crank-connecting rod mechanism 3 includes a motor mounting plate 31, a second motor 32, an eccentric wheel 33, a connecting rod 34, and a connecting block 35. The motor mounting plate 31 is mounted on the mounting bracket 5, the second motor 32 is mounted on the motor mounting plate 31, the eccentric wheel 33 is mounted on the output end of the second motor 32, one end of the connecting rod 34 is rotatably mounted on the eccentric wheel 33, and the other end is rotatably connected to the connecting block 35. The other end of the connecting block 35 is connected to the cutter bar 8. The second motor 32 drives the eccentric wheel 33, the eccentric wheel 33 drives the connecting rod 34, the connecting rod pushes the connecting block 35, and the connecting block 35 drives the cutter bar 8 to perform reciprocating linear motion. This allows the moving blade 9 mounted on the cutter bar 8 and the blade protector 10 to work together to cut the tea leaves. By adopting a scissor-like structure to harvest the tea leaves, damage to the tea leaves is greatly reduced, and the quality of the tea leaves is improved.
[0028] Furthermore, the pressing device includes a third motor 16, a rotating shaft 15, and multiple pressing rods 14. The rotating shaft 15 is rotatably mounted above the mounting frame 5, and the multiple pressing rods 14 are evenly arranged around the outer circle of the rotating shaft 15. The third motor 16 is mounted on the mounting frame 5, and the output end of the third motor 16 is connected to the rotating shaft 15 through a sprocket and chain transmission mechanism. The third motor 16 drives the rotating shaft 15 to rotate through the sprocket and chain transmission mechanism, and the rotating shaft 15 drives the multiple pressing rods 14 to rotate. By rotating the pressing rods 14, the tea leaves are pressed down, thus pressing down the tea leaves and facilitating the cutting of the moving blade 9.
[0029] Furthermore, the sprocket and chain drive mechanism includes a main sprocket 17, a driven sprocket 19, and a chain 18. The main sprocket 17 is mounted on the output end of the third motor 16, the driven sprocket 19 is mounted on the rotating shaft 15, and the chain 18 is sleeved between the main sprocket 17 and the driven sprocket 19.

[0030] Furthermore, both sides of the bottom of the mounting frame 5 are equipped with rotatable wheels 13, which support the mounting frame 5 and facilitate walking, making walking more stable and smooth.
[0031] In this embodiment, an automatic tea harvester for Liubao tea utilizes a first motor 22 to drive a belt drive mechanism, which in turn drives a drive wheel 21 to rotate. The drive wheel 21 engages with a moving track, enabling the harvester to move forward and backward. The forward and reverse rotation of the first motor 22 allows the harvester to move stably on the plantation, increasing harvesting efficiency. Simultaneously, a third motor 16 drives a rotating shaft 15 via a sprocket and chain drive mechanism. The rotating shaft 15 then rotates multiple pressing rods 14. The tea leaves are pressed down by the rotating pressing rod 14, making it easier for the moving blade 9 to cut them. Simultaneously, the second motor 32 drives the eccentric wheel 33, which in turn drives the connecting rod 34. The connecting rod pushes the connecting block 35, which in turn drives the blade rod 8 in a reciprocating linear motion. This, combined with the working of the moving blade 9 and the blade protector 10 mounted on the blade rod 8, cuts the tea leaves. The harvested tea leaves fall onto the belt conveyor 11 and are transported into the collection box 12 for storage.
