Abstract

This utility model relates to a multifunctional electric remote-controlled tea tree pruning machine. The power shafts of four pruning motors are aligned in a straight line and pass through the through-holes of the mounting chamber. The power shafts of the first and third motors are fitted with short bushings, while the power shafts of the second and fourth motors are fitted with long bushings. The center holes of four disc-shaped fine-tooth saw blades pass through the motor power shafts, and bushing pressure plates are then fitted on them. Finally, nuts are tightened to secure the machine. Five pointed sections are provided along the edge of the motor mounting chamber opening, with three pointed sections located where adjacent disc-shaped fine-tooth saw blades overlap, and the other two pointed sections located on the outer sides of the disc-shaped fine-tooth saw blades at both ends. This utility model controls the walking speed, enabling the disc-shaped fine-tooth saw blades to effectively cut the stumps and branches of the tea tree. The material-stopping protrusion in front of the disc-shaped fine-tooth saw blades effectively prevents the tea tree stumps and branches from being cut by two saw blades simultaneously, thus avoiding motor stalling. This utility model uses a 48-volt lithium battery as its power source, and under normal conditions, it can operate continuously for four hours.

Description

Technical Field

[0001] This utility model relates to a tea tree pruning machine, and more particularly to an electric remote-controlled tea tree pruning machine. Background Technology

[0002] The pruning of old tea trees is a laborious and demanding task in tea plantations. Because old tea trees typically have thicker trunks, manual pruning with hand-held knives or portable cutting tools cannot achieve the desired pruning efficiency and cutting quality. Therefore, a high-powered, high-speed cutting tool, coupled with sufficiently heavy machinery, is needed to meet the requirements of pruning old tea trees. Summary of the Invention

[0003] The purpose of this invention is to provide an electric remote-controlled tea tree pruning machine to solve the various problems currently faced in tea tree pruning.

[0004] To achieve the above objectives, the technical solution of this utility model is to provide a multi-functional electric remote-controlled tea tree pruning machine, which comprises a tracked walking assembly, a gantry support, a pruning blade assembly, a conveyor belt assembly, a motor, a battery, and a housing. The gantry support is fixed above the tracked walking assembly, and the pruning blade assembly and the conveyor belt assembly are fixed to the gantry support. The battery and motor provide power to the tracked walking assembly, the pruning blade assembly, and the conveyor belt assembly. The wireless remote control controls the operation of each motor through a signal receiving and execution circuit. The pruning blade assembly consists of four motors, four disc-shaped fine-tooth saw blades, a motor mounting chamber, and a chamber cover. The power shafts of the four motors are aligned in a straight line and pass through the through holes of the mounting chamber. The power shaft of the third motor is fitted with a short bushing, while the power shafts of the second and fourth motors are fitted with long bushings. The center holes of the four disc-shaped fine-tooth saw blades pass through the motor power shafts, and then bushing pressure plates are fitted on them. Finally, nuts are tightened to secure them. The cover covers the top of the installation chamber. Five pointed parts are provided on the edge of the opening of the motor installation chamber. The first pointed part is located outside the first disc-shaped fine-tooth saw blade, the second pointed part is located where the first and second disc-shaped fine-tooth saw blades overlap, the third pointed part is located where the second and third disc-shaped fine-tooth saw blades overlap, the fourth pointed part is located where the third and fourth disc-shaped fine-tooth saw blades overlap, and the fifth pointed part is located outside the fourth disc-shaped fine-tooth saw blade.

[0005] In the above technical solution, the first and third motors of the trimmer assembly rotate clockwise, while the second and fourth motors rotate counterclockwise.

[0006] In the above technical solution, the conveyor belt assembly includes a conveyor belt motor and reducer, a drive roller, a driven roller, and a conveyor belt. The main shaft of the conveyor belt motor is fixed to the worm gear of the reducer, the worm wheel of the reducer is fixed to one end of the output shaft, and the other end of the output shaft is connected to the drive roller of the conveyor belt through a coupling. The conveyor belt is wound between the drive roller and the driven roller.

[0007] In the above technical solution, the tracked walking assembly includes a walking motor, a reducer, a sprocket, and a tracked walking mechanism. The power shaft of the walking motor is fixedly connected to the worm gear of the reducer. The worm gear of the reducer is connected to one end of the output shaft, and a sprocket is fixed to the other end of the output shaft. The sprocket is engaged and linked with the drive sprocket in the tracked walking mechanism through a chain.

[0008] The advantages of this utility model are: 1. It adopts a transmission structure design with a single high-speed motor and a single disc fine-tooth saw blade, and through the control of the walking speed of the table reaper, the disc fine-tooth saw blade can effectively cut the stumps and branches of tea trees.

[0009] 2. The material-stopping protrusion set in front of the disc-shaped fine-tooth saw blade effectively prevents the motor from stalling when tea tree stumps are cut by two saw blades at the same time.

[0010] 3. This utility model uses a 48-volt lithium battery as its power source, which can operate continuously for four hours under normal conditions. Attached Figure Description

The walking motor and reducer 3 provide power to the tracked walking assembly 6, the trimming motor 4 provides power to the trimming tool assembly 8, and the conveyor motor and reducer 5 provides power to the conveyor belt assembly 9. The wireless remote controller 1 sends commands to the signal receiving and execution circuit device 2, thereby controlling the walking motor 3, the trimming motor 4, and the conveyor motor 5. The lithium battery 10 provides power to the motors, and the charging adapter 11 replenishes the lithium battery 10 with power.

[0021] The structural assembly diagram of the tea tree pruning machine in this embodiment is attached. Figure 2 As shown.

[0022] The tea tree pruning machine pruning blade assembly of this embodiment is as follows: Figure 3 Appendix Figure 4 and attached Figure 5As shown. The drive shafts of the four motors 102 are aligned in a straight line and pass through the through holes of the mounting chamber 101. The drive shafts of the first and third motors are fitted with short bushings 105, and the drive shafts of the second and fourth motors are fitted with long bushings 106. The center holes of the four disc-shaped fine-tooth saw blades 103 pass through the motor drive shafts 108, and then bushing pressure plates 107 are fitted on them. Finally, they are tightened and fixed with nuts 109. The chamber cover covers the top of the mounting chamber. Five pointed parts 104 are provided on the edge of the motor mounting chamber opening. The first pointed part is located outside the first disc-shaped fine-tooth saw blade, the second pointed part is located at the overlap of the first and second disc-shaped fine-tooth saw blades, the third pointed part is located at the overlap of the second and third disc-shaped fine-tooth saw blades, the fourth pointed part is located at the overlap of the third and fourth disc-shaped fine-tooth saw blades, and the fifth pointed part is located outside the fourth disc-shaped fine-tooth saw blade. In this embodiment, when the pruning cutter is operating, the first and third motors rotate clockwise at high speed, while the second and fourth motors rotate counterclockwise at high speed. A pointed, protruding section 104 in front of the fine-toothed disc saw blade effectively prevents the tea tree stumps and branches from being cut simultaneously by both saw blades, thus avoiding motor stalling. In this embodiment, to improve the cutting effect of the tea tree stumps and branches by the pruning machine, a high-speed motor directly drives the fine-toothed disc saw blade without deceleration. With effective control of the pruning machine's travel speed, the high-speed rotating fine-toothed disc saw blade can quickly cut the tea tree stumps and branches.
