Description

Technical Field

[0001] The utility model relates to the technical field of agricultural fruit tree pruning, in particular to an agricultural fruit tree pruning device. Background Art

[0002] Agricultural fruit tree pruning is a technical measure to cut off part of the fruit tree's nutritional organs in order to adjust the crown structure and renew the branch composition. The crown of a fruit tree expands with age. Too many branches and leaves will inevitably result in dense outside and hollow inside, premature aging of the tree, serious alternate bearing, and reduced fruit yield and quality. Timely and reasonable pruning can achieve a balanced yield and facilitate management. In addition, pruning is also a means to coordinate the growth of the aboveground part with the root system.

[0003] However, the existing pruning device does not carry a grinding stone device. When the pruning device becomes dull during pruning, it is inconvenient for the operator to rub the pruning device, which further affects the pruning effect and pruning efficiency of the pruning device.

[0004] For example, Chinese patent CN212278958U discloses a pruning device for fruit tree seedlings. A device for friction sharpening the pruning device is added to the original pruning device for fruit tree seedlings. When the device becomes blunt during use, it can be friction sharpened by the friction sharpening device to ensure the pruning effect and efficiency.

[0005] However, the length of the pruning device is fixed, so that the aid of a ladder is required when pruning taller fruit trees, which is inconvenient.

[0006] For this reason, we urgently need to provide an agricultural fruit tree pruning device with adjustable length. Utility Model Content

Therefore, after the connecting block at the rear end of the extension rod is slid into the mounting groove, the plug rod is pushed by the spring rebound, and the end of the plug rod away from the spring is pushed into the plug hole, so that the connecting block can be fixed to the mounting groove, so that the extension rod can be fixed to the front end of the handle, or the two extension rods can be fixed, so that the overall length of the pruning device can be extended, so as to facilitate pruning of agricultural fruit trees of different heights.

[0013] A further improvement is that the replacement unit includes a mounting plate and bolts, wherein the mounting plate is fixedly connected to the upper side of the blade, and the bolts are connected to the front and rear ends inside the mounting plate.

[0014] A further improvement is that the front and rear ends of the right side of the first support rod and the front and rear ends of the left side of the second support rod are provided with thread grooves, the front and rear ends of the mounting plate are provided with round holes, the outer side of the bolt is slidably connected to the inner side of the round hole, and the outer side of the bolt is threadedly connected to the inner side of the thread groove. Therefore, after the bolt passes through the round holes at the front and rear ends of the mounting plate and is then threadedly connected to the thread groove, the mounting plate can be fixed to the outer sides of the first support rod and the second support rod, so that the blade can be fixed to the outer sides of the first support rod and the second support rod.

[0015] A further improvement is that the outer sides of the handle and the extension rod are provided with anti-skid patterns, so that when the pruning device is used to prune fruit trees by holding the handle or the extension rod, the anti-skid patterns on the outer sides of the handle or the extension rod contact the palm, so that the pruning device can be grasped more firmly.

[0016] In summary, the present application discloses an agricultural fruit tree pruning device.

[0017] According to the technical solution, after the connecting block at the rear end of the extension rod is slid into the installation groove, the insertion rod is pushed by the spring rebound, and the end of the insertion rod away from the spring is pushed into the insertion hole, so that the connecting block can be fixed to the installation groove, thereby the extension rod can be fixed to the front end of the handle, or the two extension rods can be fixed to each other, so that the overall length of the pruning device can be extended to facilitate pruning of agricultural fruit trees of different heights.

[0018] Furthermore, by rotating the bolt to remove it from the threaded groove, the mounting plate and the blade can be removed from the outer sides of the first support rod and the second support rod, so that the blade can be disassembled and replaced when the blade is damaged due to long-term use.
