Description

Technical Field

[0001] The utility model relates to the technical field of fruit tree planting, in particular to a robot for pruning side branches of fruit trees. Background Art

[0002] Fruit trees refer to trees that can bear fruit and are planted in gardens or orchards, such as apple trees, pear trees, peach trees, etc. Pruning is a horticultural management technique that involves cutting, shaping, thinning and trimming fruit trees, with the aim of adjusting the crown structure, promoting plant growth, increasing yield and improving fruit quality. Pruning can promote the growth of fruit trees, adjust the crown shape, and allow light, air and water to enter the crown better, which is beneficial to the growth and development of plants. Reasonable pruning can promote the differentiation of flower buds and fruiting of fruit trees, and increase yield. Through pruning, the size, shape and color of fruits can be adjusted, the quality can be improved, and the commodity value can be increased. Pruning allows ventilation and light transmission in the crown of fruit trees, reduces the breeding and spread of pests and diseases, and helps the healthy growth of fruit trees. Regular pruning can extend the life of fruit trees, keep the crown healthy, and reduce diseases and dieback. Therefore, fruit tree pruning is an important horticultural management measure that helps to increase the yield and quality of fruit trees and maintain healthy growth.

[0003] In the prior art, in order to prune branches at higher positions, a support rod with an extension function is usually used to support the pruning device. However, in actual operation, this pruning method requires the staff to continuously drive the pruning device to move up and down to prune branches at different positions. This is laborious and may lead to reduced pruning efficiency. Therefore, the utility model provides a fruit tree side branch pruning robot to solve the problems raised in the above background technology. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art, and the proposed fruit tree side branch pruning robot controls the pruning mechanism by holding a support rod to move it up and down on the surface of the fruit tree. In this way, no matter whether the side branches at different heights are pruned, there is no need to frequently move the support rod, thereby greatly reducing physical exertion and improving work efficiency.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fruit tree side branch pruning robot comprises a support rod, a positioning groove is provided at the front end of the support rod, a controller is fixedly arranged at the lower end of one side of the support rod, an upper fixing sleeve is fixedly arranged at the upper end of the support rod, and a pruning mechanism is slidably arranged at the upper end of the support rod body;

[0007] The trimming mechanism comprises two rotating frames, a support plate, an electric trimmer, a driving motor, a plurality of supporting telescopic rods, a plurality of contraction springs, two contraction frames, two power cams, two contraction telescopic rods, a stabilizing sleeve, a rubber connecting ring and a limit strip;

[0008] The two power cams are rotatably arranged at the two sides between the two rotating frames, the driving motor is fixedly arranged at one side of one of the front ends of the two rotating frames, the output end of the driving motor is fixedly connected to the front end of one of the two power cams, and the two retracting frames are rotatably connected to the lower ends of the two rotating frames;

[0009] The plurality of supporting telescopic rods are respectively fixedly connected in pairs to the inside of the two contraction frames, the plurality of contraction springs are respectively fixedly connected in pairs to the inside of the two contraction frames, the stabilizing sleeve is rotatably arranged between the two rotating frames at an upper end position, the limiting bar is fixedly arranged in the inside of the stabilizing sleeve at a front end, the limiting bar is slidably arranged in the inside of the positioning groove, and the stabilizing sleeve is slidably arranged on the support rod body at an upper end;

[0010] The rubber connecting ring is fixedly arranged on the upper end of the stabilizing sleeve, the supporting plate is fixedly arranged on the upper end of the stabilizing sleeve, the two retractable telescopic rods are respectively fixedly arranged on the two ends inside the stabilizing sleeve, and the electric trimmer is fixedly arranged on one side of the upper end of the supporting plate.

[0011] Through the above technical solution, when using the pruning robot to prune the side branches of fruit trees, the staff can hold the support rod to control the pruning mechanism to move up and down on its surface, so that when pruning side branches of different heights, there is no need to drive the support rod up and down to move, which greatly saves effort and improves work efficiency. The driving motor can drive the power cam to rotate, and the friction between the power cam and the surface of the support rod is large, so that the entire pruning mechanism can be driven to move on the support rod, and the support rod is clamped by two power cams, which improves the stability during the movement. The support telescopic rod and the contraction spring can always tighten the two contraction frames. , and then the power cams on both sides are tightly fitted to the two sides of the support rod, further improving the stability during movement. When the power cam drives the rotating frame to move up and down, the rotating frame will drive the upper stabilizing sleeve to move, and the stabilizing sleeve is limited by the limit bar, which improves its stability during movement. The retracting telescopic rod can pull the stabilizing sleeve firmly onto the support rod body to avoid shaking on the thinner part above the support rod, and it is connected to the upper support plate through a rubber connecting ring, which facilitates deformation and is also connected to the support plate. An electric scissors structure is set inside the electric trimmer, and the scissors part is driven to close by the internal motor to realize pruning.

[0012] Furthermore, an anti-slip sleeve is fixedly provided on the lower end of the support rod shaft, and a support handle is fixedly provided on one side of the support rod shaft near the lower end;

[0013] Through the above technical solution, the anti-slip sleeve can increase the friction when the worker holds the support rod, which is convenient for use. The other hand can also hold the support handle to perform pruning work, which improves stability during the work process.

[0014] The utility model has the following beneficial effects:

[0015] 1. When using the fruit tree side branch pruning robot to perform the fruit tree side branch pruning task, the staff can control the pruning mechanism by holding the support rod to move it up and down on the surface of the fruit tree. In this way, no matter whether the side branches at different heights are pruned, there is no need to frequently move the support rod, thereby greatly reducing physical exertion and improving work efficiency.

[0016] 2. The fruit tree side branch pruning robot proposed in the utility model can always keep the two retracting frames closely connected through the coordinated action of the supporting telescopic rod and the retracting spring when controlling the pruning mechanism to move up and down. On this basis, the power cams on both sides can be closely fitted on both sides of the support rod, thereby improving the stability during the movement. At the same time, in the process of the power cam driving the rotating frame to move up and down, the stabilizing sleeve can achieve effective limit through the limit bar, further enhancing the stability during the movement.
