Description

Technical Field

[0001] The utility model relates to the technical field of apple pruning, in particular to a pruning device for apple cultivation. Background Technique

[0002] Apple pruning is a common horticultural practice. After pruning the branches of apple trees, it can help the fruit trees grow better. The purpose is to remove weak, crossed and overcrowded branches, promote ventilation and light in the fruit trees, thereby reducing the risk of diseases. At the same time, it stimulates the growth of new branches, improves the fruit quality and yield, and keeps the tree shape beautiful and symmetrical to facilitate the uniform distribution of fruits.

[0003] For this, Chinese Patent Publication No. CN221283869U2 discloses a pruning device for apple cultivation. It can be seen from the above solution that the asynchronous motor can drive the lift and the lifting rod to rotate, drive the cutting assembly to rotate, and cooperate with the cylinder to realize the adjustment of the pruning angle, so as to better complete the pruning. At the same time, the crusher and the collection box rotate with the cutting assembly for better collection. However, when the existing pruning device for apple cultivation is specifically used, there are still some problems: when solving the problem that the pruning angle cannot be adjusted, the weak branches of apple tree branches are too close to the root, and the lengths of the diseased branches are different. The lengths of the cutting blades and the support arms are fixed, making it difficult for the cutting blades to approach the roots of the longer weak branches, resulting in incomplete crushing and cutting of the weak branches, and there are still residual parts of the weak branches. Therefore, the growth of apple trees is still hindered, which is not conducive to the growth of apple trees. Summary of the Utility Model

[0026] The cutting blade telescopic adjustment mechanism 2 includes a stainless steel support plate 201. One side of the upper end of the stainless steel support plate 201 is fixedly connected to a first fixing block 202. The top of one side surface of the first fixing block 202 is fixedly connected to a telescopic adjustment rod 203. One end of the telescopic adjustment rod 203 is fixedly connected to a support sliding rod 204. The surface of the support sliding rod 204 is slidably connected to a second fixing block 205. One end of the second fixing block 205 is slidably connected to a rubber limiting rod 206. The support sliding rod 204 is fixed to one end of the connecting support block 3. Through the setting of the cutting blade 5 and the cutting blade telescopic adjustment mechanism 2, the limitation of the fixed length of the cutting blade 5 and the support arm is removed, so that the cutting blade 5 can penetrate deep enough into the apple tree branch and approach the root, and the weak and diseased branches can be crushed and cut from the root of the apple tree branch. The remaining part is cut off so that the apple tree can develop normally without affecting growth. While the support sliding rod 204 slides in the second fixing block 205, it drives the rubber limiting rod 206 to slide in the through hole at the other end of the second fixing block 205, and the rubber material on the surface of the rubber limiting rod 206 can achieve limiting friction with the second fixing block 205, so that the cutting blade 5 can be positioned when moving horizontally forward.

[0027] Please refer to Figure 4 , the cutting angle adjustment mechanism 1 includes an arc-shaped groove support plate 101. One end of the arc-shaped groove support plate 101 is slidably connected to a telescopic support rod 102. One side of the upper end of the telescopic support rod 102 is fixedly connected to a third fixing block 103. One end of the telescopic support rod 102 is rotatably connected to an auxiliary support block 104. A semi-circular groove is opened at one end of the arc-shaped groove support plate 101. The telescopic support rod 102 can slide up and down in the semi-circular groove in a limited manner and change the inclination angle, so that the cutting angle of the cutting blade 5 is also changed.

[0028] Please refer to Figures 3 to 4, the lower end of the fixed block three 103 is fixedly connected to one side of the upper end of the arc-shaped groove support plate 101. One end of the rubber limit rod 206 is fixedly connected to one end of the surface of the support slide rod 204. One side of the upper end of the stainless steel support plate 201 is fixedly connected to the lower end of the fixed block two 205.

The middle part of the surface of the height-adjusting sleeve rod 6 is fixedly connected with a sliding limit rod 7. One end of the sliding limit rod 7 is slidably connected with an H-shaped support plate 8. The H-shaped support plate 8 serves as the bottom support of the support screw 9. While the height-adjusting sleeve rod 6 rotates on the surface of the support screw 9, it can lift the sliding limit rod 7 to adjust the support height of the cutting blade 5.

[0030] Please refer to Figures 1 to 2 , the inner bottom wall of the H-shaped support plate 8 is fixedly connected with a support screw 9. The surface of the support screw 9 is threadedly connected with the inner wall of the height-adjusting sleeve rod 6. The upper end of the height-adjusting sleeve rod 6 is lapped with one end of the sliding limit rod 7. The lower end of the H-shaped support plate 8 is fixedly connected with a support base 10. A chute adapted to the sliding limit rod 7 is opened on the front surface of the H-shaped support plate 8, and one end of the sliding limit rod 7 is slightly smaller than the width of the chute opened on the H-shaped support plate 8, so that the sliding limit rod 7 will not be hindered by friction when sliding on the H-shaped support plate 8.

[0031] Please refer to Figures 1 to 2 , one side of the upper end of the support base 10 is fixedly connected with a fixing rod 11.

[0033] The working principle of the present utility model is as follows:

[0034] After moving the pruning device under the apple tree and limiting and fixing the pruning device, toggle the telescopic support rod 102 to make it slide in the semi-circular chute of the arc-shaped chute support plate 101, change the cutting angle of the cutting blade 5, and at the same time rotate the sleeve rod 6 for height adjustment to make it rotate in the support screw 9, drive the cutting blade 5 to rise, drive the rotating motor 4 to drive the cutting blade 5 to cut the diseased branches. When encountering a longer diseased branch, stop the rotating motor 4, and at the same time hold the rubber limit rod 206 to make it slide in the second fixed block 205. The rubber limit rod 206 and the second fixed block 205 have limit friction, so that the position of the cutting blade 5 is changed. Restart the rotating motor 4 to drive the cutting blade 5 to rotate and cut off the longer diseased branch from the root, completing the pruning operation of the apple tree branches.
