Technical Field

[0001] This utility model relates to the field of fruit tree pruning technology, specifically to a height-adjustable automatic fruit tree pruning machine. Background Technology

[0002] Fruit tree pruning is a technique that involves removing a portion of the fruit tree's vegetative organs to adjust the canopy structure and renew the branch composition. As fruit trees age, their canopies expand, and excessive foliage inevitably leads to a dense outer canopy and an inner hollow, premature tree decline, severe alternate bearing (biennial bearing), and reduced fruit yield and quality. Timely and proper pruning helps regulate the distribution of branches and leaves, balance growth and fruiting, and maintain a balance in growth vigor among plants and between main branches on a single plant, thereby achieving balanced yield and facilitating management.

[0003] When fruit growers prune fruit trees, they need to climb the trees to prune the higher branches, which is somewhat dangerous. In addition, pruning a large number of fruit trees will consume a lot of the growers' physical strength and increase their burden.

[0004] Therefore, there is a need for an adjustable automatic fruit tree pruning machine that can automatically prune fruit trees at adjustable height. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes a height-adjustable automatic fruit tree pruning machine that can automatically adjust the height and the angle of the cutting disc, facilitating the pruning of branches at different heights and reducing the workload of fruit farmers.

This solution can move the base 1 by pushing the push handle 171 or use a vehicle to tow and transport it to a designated location for fruit tree pruning.

[0020] Reference Figure 1 , Figure 2 and Figure 3As shown, specifically, a support plate 14 is fixed to the top edge of the base 1 to support the lower end of the support wall 2. The upper end of the support plate 14 has a rotating groove 141 for the lower end of the support wall 2 to rotate at a certain angle, facilitating the lifting of the other end of the support wall 2. The inner wall of the rotating groove 141 has symmetrically arranged rotating holes 142 for connecting the rotating shaft 25. A support wall 2 is located above the base 1 to support the cutting disc 242, allowing the cutting disc 242 to adjust its height. One end of the support wall 2 is located inside the rotating groove 141, and the side wall of one end of the support wall 2... A rotating shaft 25 is fixed to connect the support wall 2 to the support plate 14. The rotating shaft 25 is movably inserted into the inner side of the rotating hole 142. A moving groove 21 is provided in the middle of the support wall 2. When one end of the support wall 2 is raised, the support column 162 adjusts its position in it. The moving groove 21 passes through the support wall 2. A hydraulic device 16 is fixed on the other side of the top surface of the base 1 (the hydraulic device 16 is prior art. The specific operation mode and principle can be referred to the electric hydraulic cylinder in the prior art. It is controlled by an external power source for opening and closing, so it is not described in detail here). The output end of the hydraulic device 16 A movable frame 161 is fixed to the support column 162. The movable frame 161 is located outside the support wall 2. The support column 162 is fixed to the inner wall of the upper end of the movable frame 161, which can drive one end of the support wall 2 to rise or fall. The support column 162 passes through the movable groove 21. A vertical plate 15 is symmetrically fixed to the top surface of the base 1 to reduce the lateral force on the hydraulic equipment 16. The side wall of the vertical plate 15 is provided with a sliding groove 151 for the sliding block 163 to slide up and down. The sliding groove 151 passes through the vertical plate 15. Sliding blocks 163 are symmetrically fixed to the outer wall of the lower end of the movable frame 161. Block 163 can only slide up and down inside the sliding groove 151. The lateral force it receives will act on the vertical plate 15, thereby reducing the lateral force on the hydraulic device 16. Block 163 is located inside the sliding groove 151. In this solution, the hydraulic device 16 pushes the moving frame 161 to move upward. The moving frame 161 drives the support column 162 to move upward. The support column 162 pushes one end of the support wall 2 to lift up, thereby causing the support wall 2 to drive the cutting disc 242 to rise to the required height. The height is automatically adjusted, and the adjustment range is large, which can adapt to the pruning needs of different positions of the fruit tree.

The base 1 can be moved to the fruit tree to be pruned by pushing the push handle 171 or by using other vehicles for towing. The hydraulic device 16 pushes the moving frame 161 to rise, which in turn drives the support column 162 to rise. The support column 162 pushes one end of the support wall 2 to lift, thereby raising the cutting disc 242 to the required height. Then, the vertical, horizontal, or oblique cut is determined according to the position and angle of the branch. The first motor 23 drives the connecting chamber 231 to rotate at a certain angle, thereby adjusting the angle of the cutting disc 242 to match the angle of the branch. Finally, the second motor 241 and the electric push rod 232 are started. The second motor 241 drives the cutting disc 242 to rotate, and the electric push rod 232 pushes the connecting plate 24 to move the cutting disc 242 toward the branch for cutting, thus completing the pruning of the fruit tree. A storage box 13 is provided inside the storage compartment 12 on the top surface of the base 1. The storage box 13 can be used to store various tools. By pulling the limiting rod 18 out from the inside of the limiting groove 19, the storage box 13 can be pulled out through the fixing block 131 to use the tools inside.
