Description

Technical Field

[0001] This utility model belongs to the technical field of tea picking equipment, and particularly relates to a track-type tea picking machine. Background Technology

[0002] Tea picking is a tea garden management operation with a long history. With the development of technology, people generally use track-type tea picking machines to pick tea leaves. Tea picking machines are agricultural machines that harvest tender tea leaves from the top of tea trees. Among them, track-type tea picking machines are reliable, easy to operate, and suitable for large tea gardens.

[0003] Existing track-mounted tea-picking machines require workers to manually support the collection bags to prevent tea leaves from piling up at the bag openings. As the amount of tea leaves increases, this requires significant physical exertion and increases the workload for workers. Therefore, we propose a track-mounted tea-picking machine. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A track-type tea-picking machine includes a frame, on which a guide box is fixedly installed. Tea-picking knives are installed inside the guide box, and a detachable tea collection bag is installed at the outlet of the guide box. A support seat is provided at the bottom of the tea collection bag, and a swing arm is connected to the outside of the support seat. A connecting seat is hinged to the end of the swing arm away from the support seat, and the connecting seat is fixedly connected to the frame.

[0006] As a preferred embodiment of the above technical solution, the frame is fixedly connected to an arc-shaped sliding plate, the swing arm is fixedly connected to a threaded rod, the threaded rod is slidably connected to the arc-shaped sliding plate, and the threaded rod is threadedly connected to a fastening nut, the fastening nut abutting against the arc-shaped sliding plate.

[0007] As a preferred embodiment of the above technical solution, the bottom of the frame is fixedly connected with wheels.

[0008] As a preferred embodiment of the above technical solution, a plurality of through holes are provided on one side of the material guide box, and an air guide pipe is fixedly fitted inside the inner ring of the through holes, and a fan is installed inside the air guide pipe.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. The swing arm of this utility model will drive the lifting seat to rotate around the hinge point of the connecting seat. The weight of the lifting seat will straighten the tea collection bag, so that the tea leaves picked by the tea picking knife can fall directly to the bottom of the tea collection bag. This can avoid manually supporting the tea collection bag and reduce the physical exertion and labor intensity of employees.

[0011] 2. This utility model utilizes the threaded engagement between the fastening nut and the threaded rod. Rotating the fastening nut allows the arm to move away from or closer to the arc-shaped sliding plate. When the fastening nut moves away from the arc-shaped sliding plate, the swing arm can swing freely. When the fastening nut is tightly fitted with the arc-shaped sliding plate, the swing arm can no longer swing. This allows tea collection bags of different sizes to be installed between the guide box and the support seat. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the track-type tea picking machine includes a frame 10, a guide box 20 is fixedly installed on the frame 10, a tea picking knife 21 is installed inside the guide box 20, and a detachable tea collection bag 30 is installed at the discharge port of the guide box 20. A support seat 40 is provided at the bottom of the tea collection bag 30, and a swing arm 41 is connected to the outside of the support seat 40. A connecting seat 42 is hinged to the end of the swing arm 41 away from the support seat 40, and the connecting seat 42 is fixedly connected to the frame 10.

[0020] It should be noted that the uprights of the frame 10 have a lifting function. By movably fitting the sleeve rod inside the sleeve and installing the cylinder inside the sleeve, the sleeve rod is fixedly connected to the output end of the cylinder. After starting the cylinder, the overall height of the frame 10 can be controlled. It can be adjusted according to the height of different tea trees so that the tea-picking knife 21 can always be in contact with the tender buds of the tea tree.

[0021] Specifically, the swing arm 41 will drive the lifting seat 40 to rotate around the hinge point of the connecting seat 42. The weight of the lifting seat 40 will straighten the tea collection bag 30, so that the tea leaves picked by the tea picking knife 21 can fall directly to the bottom of the tea collection bag 30. This avoids the need to manually support the tea collection bag 30, reducing the physical exertion and labor intensity of employees.

[0022] like Figure 1 and Figure 2 As shown, the frame 10 is fixedly connected to an arc-shaped slide plate 45, and the swing arm 41 is fixedly connected to a threaded rod 43. The threaded rod 43 is slidably connected to the arc-shaped slide plate 45, and the threaded rod 43 is threadedly connected to a fastening nut 44, which abuts against the arc-shaped slide plate 45.

[0023] Specifically, the dot of the curved slide plate 45 coincides with the hinge point of the swing arm 41 and the connecting seat 42, so that the threaded rod 43 can slide smoothly in the inner circle of the curved slide plate 45 during the swinging process of the swing arm 41. Through the threaded engagement of the fastening nut 44 and the threaded rod 43, rotating the fastening nut 44 can move it away from or towards the curved slide plate 45. When the fastening nut 44 moves away from the curved slide plate 45, the swing arm 41 swings freely. When the fastening nut 44 is tightly attached to the curved slide plate 45, the swing arm 41 can no longer swing, so that tea collection bags 30 of different sizes can be installed between the guide box 20 and the support seat 40.

[0024] like Figure 1 and Figure 2 As shown, the bottom of the frame 10 is fixedly connected with a traveling wheel 11.

[0025] Specifically, the walking wheels 11 are compatible with the tracks installed in the tea garden.

[0026] like Figure 2 and Figure 3 As shown, a number of through holes are provided on one side of the material guide box 20, and an air guide pipe 22 is fixedly fitted inside the inner ring of the through holes. A fan 23 is installed inside the air guide pipe 22.

[0027] Specifically, the air duct 22 is set at an angle, with the air inlet of the air duct 22 close to the tea picking knife 21 and the air outlet close to the discharge port of the material box 20, so that the tea leaves picked by the tea picking knife 21 will be blown into the tea collection bag 30 by the fan 23.

[0028] Working principle: The traveling wheels 11 are adapted to the track installed in the tea garden, allowing the frame 10 to move along the track. The uprights of the frame 10 have a lifting function. By movably fitting the sleeve rod into the sleeve and installing the cylinder inside the sleeve, the sleeve rod and the output end of the cylinder are fixedly connected. After starting the cylinder, the overall height of the frame 10 can be controlled and adjusted according to the height of different tea trees, ensuring that the tea-picking knife 21 is always in contact with the tender buds of the tea tree. Because the air duct 22 is inclined, the air inlet of the air duct 22 is close to the tea-picking knife 21, and the air outlet is close to the discharge port of the material box 20. Therefore, the tea leaves picked by the tea-picking knife 21 will be blown into the tea leaves by the fan 23. Inside the collection bag 30, the dot of the arc-shaped slide plate 45 coincides with the hinge point of the swing arm 41 and the connecting seat 42, so that the threaded rod 43 can slide smoothly in the inner circle of the arc-shaped slide plate 45 during the swing of the swing arm 41. Through the threaded engagement of the fastening nut 44 and the threaded rod 43, rotating the fastening nut 44 can move it away from or towards the arc-shaped slide plate 45. When the fastening nut 44 moves away from the arc-shaped slide plate 45, the swing arm 41 swings freely. When the fastening nut 44 is tightly fitted with the arc-shaped slide plate 45, the swing arm 41 can no longer swing, thus enabling the collection bags 30 of different sizes to be installed between the guide box 20 and the support seat 40.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
