[0022] Example 1:

[0023] Please see Figures 1-4 As shown, this utility model provides a self-propelled tea picking machine, including a tracked vehicle body 1. A support frame 8 is movably connected to the left side of the tracked vehicle body 1 via a bearing. A holding box 6 is fixedly installed at the left end of the support frame 8. A second hydraulic cylinder 10 is fixedly installed at the left end of the tracked vehicle body 1. A conveying shell 12 is fixedly installed at the output end of the second hydraulic cylinder 10. A second electric cutter 13 is fixedly installed at the lower right end of the conveying shell 12. A drive motor 21 is fixedly installed at the lower end of the front surface of the conveying shell 12. A drive roller 20 is fixedly installed at the output end of the drive motor 21. The back of the drive roller 20 is movably connected to the lower end of the inner cavity of the conveying shell 12 via a bearing. A conveyor belt 19 is drivenly connected to the surface of the drive roller 20. A rubber scraper 18 is fixedly connected to the surface of the conveyor belt 19. The surface of the rubber scraper 18 contacts the inner cavity of the conveying shell 12.

[0024] In this technical solution, the tracked vehicle 1 can move between the open spaces on both sides of a row of tea trees during the tea picking process. The second hydraulic cylinder 10, the conveying shell 12, and the second electric cutter 13 allow for easy height adjustment of the second electric cutter 13 during tea picking, enabling it to separate the tea leaves from the tea trees during the overall movement. With the coordinated action of the drive motor 21, drive roller 20, rubber scraper 18, and conveying shell 12, the separated tea leaves are transported and collected into the holding box 6, thus achieving automatic tea picking. The overall operation is convenient and quick, effectively improving the efficiency of tea picking operations while significantly saving labor costs.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 2 As shown, a third hydraulic cylinder 14 is fixedly installed at the right end of the bottom of the tracked vehicle body 1. A movable plate 15 is fixedly installed at the output end of the third hydraulic cylinder 14. A first electric cutter 2 is fixedly installed on the right side of the movable plate 15. A support slide rod 16 is slidably connected between the middle ends of the two movable plates 15. The top of the support slide rod 16 is fixedly connected to the right end of the bottom of the tracked vehicle body 1. A first hydraulic cylinder 7 is movably connected between the middle end of the front surface of the container 6 and the left end of the top of the tracked vehicle body 1 through a bearing. A material handling door 9 is movably connected to the lower left end of the container 6 through a hinge.

[0027] In this technical solution, the first electric cutter 2 facilitates the pruning of branches on both sides of the tea tree during tea picking. The third hydraulic cylinder 14 and the moving plate 15 allow personnel to adjust the spacing between the two sets of first electric cutters 2 according to the width of the tea tree. The support slide 16 supports and guides the moving plate 15, preventing it from tilting due to force. The material gate 9 allows personnel to easily retrieve tea leaves from the holding box 6. The extension of the first hydraulic cylinder 7 can push the holding box 6 and the support frame 8 to rotate and tilt, facilitating the rapid discharge of tea leaves from the holding box 6.

[0028] Example 3:

[0029] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, a mesh plate 5 is fixedly connected to the upper end of the inner cavity of the container 6. A receiving hole is opened on the right side of the mesh plate 5. A guide rod 11 is slidably connected to the left end of the tracked vehicle body 1. There are two guide rods 11. The top of the guide rod 11 is fixedly connected to the left side of the outer surface of the conveyor shell 12. A guide roller 17 is movably connected to the upper end of the inner cavity of the conveyor shell 12 through a bearing. The upper end of the conveyor belt 19 is drivenly connected to the surface of the guide roller 17. A fixing frame 3 is fixedly connected to the top of the tracked vehicle body 1 around its four sides. A canopy 4 is fixedly connected to the top of the fixing frame 3.

[0030] In this technical solution, the mesh plate 5 facilitates personnel to observe the interior of the container 6, the guide slide 11 supports and guides the conveyor shell 12 to prevent it from tilting or shifting due to force, and the guide roller 17 supports and guides the upper end of the conveyor belt 19.

[0031] It should be noted that, firstly, the first hydraulic cylinder 7, the second hydraulic cylinder 10, and the third hydraulic cylinder 14 are existing technologies, and during operation, they can work together through various components such as the hydraulic pump, reversing valve, oil tank, and high-pressure oil pipe installed on the tracked vehicle body 1; secondly, the first electric cutter 2 and the second electric cutter 13 are existing technologies, both of which adopt a reciprocating cutting blade design, are made of high-strength wear-resistant alloy steel, and adopt a double blade combination (moving blade and fixed blade). The moving blade is driven by an electric motor and the speed is adjusted by a reducer, and then the rotary motion is converted into linear reciprocating motion through a crank-slider structure.

[0032] The working principle of this utility model is as follows: With the tracked vehicle body 1, it can move in the open space on both sides of a row of tea trees during the tea picking process. During the overall movement, the operator can extend or retract the second hydraulic cylinder 10 to drive the conveyor shell 12 and the second electric cutter 13 to move. This allows the second electric cutter 13 to contact the tea leaves to be picked at the top of the tea tree. As the second electric cutter 13 moves, it separates the tea leaves from the tea tree. The separated tea leaves fall to the left along the inclined surface at the lower end of the inner cavity of the conveyor shell 12. Under the action of the drive motor 21 driving the drive roller 20 to rotate, the conveyor belt 19 and the rubber scraper 18 can move. Under the action of the rubber scraper 18, the tea leaves can be moved upward along the inner cavity of the conveyor shell 12 until they fall into the holding box 6 through the opening at the upper end of the conveyor shell 12. This achieves the effect of automatic tea picking.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
