Description

Technical Field

[0001] This utility model relates to the field of tea-picking equipment technology, specifically a tea-picking machine. Background Technology

[0002] The cultivation and processing of tea has a long history in my country. Tea picking technology is an important part of tea tree cultivation technology. Traditionally, tea leaves are picked manually, which is inefficient and has high labor costs. In order to improve picking efficiency and reduce costs, tea picking machines have emerged. Tea picking machines are crop harvesting machines that pick tender tea leaves from the top of tea trees.

[0003] Tea gardens have complex terrain, and existing tea-picking machines are not well-suited to these conditions. Their stability during operation is poor, which can affect tea leaf harvesting. Furthermore, existing tea-picking machines typically consist of a drive unit, an air supply unit, a leaf-cutting unit, and a tea leaf collection unit. The basic component of the air supply mechanism in these machines is usually a fan, which is fixed to the machine, resulting in a fixed air supply angle. However, tea trees grow in different directions and at different heights. During tea picking and collection, an inappropriate air supply angle can easily cause the cut tea leaves to be blown outside the collection area, resulting in waste. Utility Model Content

[0017] Specifically, the gantry-type tracked chassis 100 enables the tea-picking machine to move, allowing it to adapt to the complex terrain of the tea garden. Whether it is a hilly slope or a muddy area, it can travel stably, ensuring that the tea-picking machine can move smoothly within the tea garden and reach different work areas. When the tea-picking machine moves along a row of tea trees, the cutting component facilitates the cutting of tea leaves along the path, realizing the picking of tea leaves.

One end of each of the two air supply pipes 330 is provided with a blowing assembly. The blowing assembly includes: a fixed shell 340, a first conveying pipe 350, a second conveying pipe 360, multiple air outlet pipes 370, and a movable seat 380. The fixed shell 340 is fixedly connected to the bearing shell 110, and the first conveying pipe 350 is disposed at the corresponding air outlet. One end of the air duct 330 and the top of the first delivery pipe 350 are provided with a connecting ring 351, which is sleeved and fixed to one end of the corresponding air supply duct 330. A rotating block 352 is fixedly connected to the first delivery pipe 350, and the top of the rotating block 352 is rotatably connected to the connecting ring 351. An elastic cylinder 353 is fixedly connected between the first delivery pipe 350 and the connecting ring 351. A second delivery pipe 360 ​​is provided at the other end of the first delivery pipe 350, and a support base 361 is sleeved and fixed to the second delivery pipe 360. The support base 361 is provided on one side of the fixed shell 340. Multiple air outlet pipes 370 are respectively The bottoms of the corresponding conveying pipes 350 and 360 are connected and fixed. A movable seat 380 is located on one side of the fixed housing 340. A fixed ring 383 is fixedly connected to the movable seat 380, and elastic cylinders 384 are fixedly connected to both sides of the fixed ring 383 between the conveying pipe 350 and 360. Two fixed seats 381 are fixedly connected to the movable seat 380, and rotating plates 382 are rotatably connected to the fixed seats 381. The conveying pipes 350 and 360 are respectively fixedly connected to the corresponding rotating plates 382. Two sliding through holes 341 are provided on the fixed housing 340. Two C-shaped plates 390 are fixedly connected to 340. A second motor 391 is fixedly connected to the C-shaped plate 390, and a screw 392 is fixedly connected to the output end of the second motor 391. One end of the screw 392 is rotatably connected to the C-shaped plate 390. A movable plate 393 is screwed onto the screw 392, and the top of the movable plate 393 contacts the inner top surface of the second motor 391. A traction plate 394 is rotatably connected to the movable plate 393. A traction seat 395 is rotatably connected to one end of the traction plate 394, and one end of each of the two traction seats 395 passes through the corresponding sliding through holes 341 and is fixedly connected to the support seat 361 and the movable seat 380 respectively.

[0022] One end of the traction seat 395 is slidably connected to the corresponding sliding through hole 341.

[0023] In practice, by starting the blower 310, air is supplied to the two air supply pipes 330 via the blower 310 and the three-way pipe 320. The flexible cylinder 353, the conveying pipe 350, the fixing ring 383, the flexible cylinder 384, and the conveying pipe 360 ​​work together to supply air to the multiple air outlet pipes 370. The air blown from the multiple air outlet pipes 370 helps the tea leaves detach from the branches during tea picking, making the picking process smoother. Simultaneously, it quickly blows the picked tea leaves into the collection assembly for easy processing. This method of collection reduces tea leaf spillage during picking, improving efficiency. Before picking, motor 391 is activated, driving screw 392 to rotate, which in turn moves moving plate 393 and traction plate 394. The moving traction plate 394 pulls and pushes traction seat 395, adjusting the position of support seat 361 or moving seat 380. When support seat 361 moves, it pulls the other end of conveying pipe 360 ​​downwards. When 80 moves, it will drive the fixed ring 383 to move. The fixed seat 381 and the rotating plate 382 work together to allow the first conveying pipe 350 and the second conveying pipe 360 ​​to deflect. Both the first elastic cylinder 353 and the second elastic cylinder 384 are elastic and can deform. The two second elastic cylinders 384 connect the first conveying pipe 350 and the second conveying pipe 360 ​​to the fixed ring 383 to prevent air leakage. When the first conveying pipe 350 deflects, it will cause the rotating block 352 to deflect as well. The first elastic cylinder 353 can... One end of the air supply pipe 330 can be connected to the first conveying pipe 350. The movable or deflected first conveying pipe 350 and second conveying pipe 360 ​​can adjust the height and position of the air outlets of multiple air outlet pipes 370, so that the air duct mechanism 300 can adjust the position of multiple air outlet pipes 370 according to the height of tea leaves being picked and the usage requirements. This allows the air duct mechanism 300 to adjust the blowing position according to different actual needs when picking tea leaves from tea trees with different production conditions, thereby improving the applicability of the tea picking machine.

[0024] In order to facilitate the operation of the utility model by the operator, a PLC controller can be set up, and the gantry tracked chassis 100, motor 231, fan 310 and motor 391 are all electrically connected to the PLC controller. The PLC controller is existing technology and will not be described in detail here.
