Description

Technical Field

[0001] This utility model relates to the field of rootstock cutting equipment, and in particular to a cutting device for setting the trunk of fruit trees. Background Technology

[0002] For fruit trees such as apples, pears, cherries, plums, apricots, and peaches, resistant rootstocks are selected as the base rootstock. Scions of superior varieties are grafted onto the rootstocks, and seedlings are propagated asexually through grafting. In the grafting process, the main trunk of the rootstock is first pruned to a suitable height to serve as the base rootstock. Then, scions of superior fruit tree varieties are grafted onto the rootstocks, which are then cultivated in the nursery to become the desired fruit tree seedlings.

[0003] Due to differences in the growth characteristics, cultivation methods, and orchard establishment of different fruit tree varieties, the height of the rootstock used as the base rootstock needs to be retained at different levels. After the main trunk of the rootstock is fixed, the height of the rootstock also varies. In the process of apple seedling propagation, when using Pingyi sweet tea or Shan Dingzi rootstock as the base rootstock and adopting the low grafting method, a rootstock with a height of 2-5 cm needs to be retained as the base rootstock. When adopting the high grafting method, a rootstock with a height of 70-80 cm needs to be retained as the base rootstock. Then, apple scions are grafted onto them. After being cultivated in the nursery, they grow into excellent apple seedlings. The required height of the rootstock also varies for different fruit tree varieties.

[0004] In the planting process of fruit tree seedlings, in order to improve the survival rate and branching rate, it is necessary to perform appropriate trunk setting on the newly planted main trunks. This process is carried out by manually cutting with scissors. However, manual cutting with scissors has technical problems such as large errors, low efficiency, high labor costs, uneven cut surfaces, and inconsistent seedling heights. Therefore, a cutting device for setting the trunks of fruit trees is proposed to solve the above problems. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides a cutting device for pruning the main trunk of fruit trees. The purpose is to improve upon the traditional manual cutting method used by fruit farmers, which suffers from large errors, low efficiency, high labor costs, uneven cutting surfaces, and inconsistent seedling heights.

A second spring is fixedly connected to the inner wall of the sleeve, a sliding frame is fixedly connected to the inner side of the second spring, and a ball bearing is rotatably connected to the inner side of the sliding frame.

[0009] Preferably, the rope is externally slidably connected inside the fixed ring, and the rope is internally fixedly connected to the outside of the slide plate.

[0010] Preferably, the outer side of the spring is fixedly connected to the inner wall of the rotating ring, and the outer side of the slide plate is slidably connected to the inner wall of the fixed ring.

[0011] Preferably, the external part of the aforementioned insertion rod is slidably connected inside the fixing ring, and the external part of the insertion rod passes through the inside of the fixing frame and is inserted into the inside of the insertion rod.

[0012] Preferably, the battery compartment and the fan are electrically connected, and the battery compartment and the cutting system are electrically connected.

[0013] Preferably, the output end of the suction pipe is fixedly connected to the right side of the bracket, and the slide frame is slidably connected to the inner wall of the housing.

[0014] Preferably, the outer surface of the ball abuts against the inner surface of the housing, and the outer surface of the ball engages with the outer surface of the collection frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves quick adjustment of the extended length of the slide rod by rotating the rotating ring, which drives the rope to pull the slide plate and compress the spring. At the same time, the insert rod is retracted into the fixed ring, thereby changing the angle of the bracket and changing the height of the cutting system. It also works with the casters to move the cutting system, saving time and effort and effectively improving the efficiency of the fixed rod.

[0017] 2. This utility model uses a fan to start the suction pipe, which draws in the dust raised by the cutting system and filters it into the collection frame. In conjunction with spring 2, the sliding frame is pushed and the ball bearings are engaged outside the collection frame, thus preventing dust from flying around and affecting the fruit farmer's operation. The collection frame can also be quickly removed to clean the dust inside. Attached Figure Description

[0030] The working principle of this utility model is as follows: When using this device, first adjust the height of the cutting system 3 according to the required height. By rotating the rotating ring 8, the rope 9 pulls the slide plate 11 to compress the spring 10, causing the insertion rod 12 to retract into the fixing ring 7 and disengage from the slide rod 5. At this time, start moving the slide rod 5 and adjust its length. When it is adjusted to the appropriate position, release the rotating ring 8. Under the limit of the fixing ring 7, the spring 10 will immediately push the slide plate 11, pushing out the insertion rod 12, so that the insertion rod 12 is inserted into the slide rod 5, fixing the slide rod 5, thereby achieving height adjustment. At this time, the switch can be used to control the battery compartment 2 to provide power to the cutting system 3 and the fan 14 to make it work. Hold the top of the bracket 1 with both hands and push the entire device to move. Through the high-speed rotation of the cutting system 3, under the action of the slide rod 5 and the universal wheel 6, the cutting system 3 contacts the fan 14. The fruit tree trunks are cut and chopped to ensure that the remaining trunks are of uniform height. During the cutting process, the blower 14 provides suction to the suction pipe 15, which draws the dust into the collection frame 20 and collects it, thus avoiding interference with the fruit farmer's operations. The resulting debris falls directly to the ground unaffected. After a period of use, the dust in the collection frame 20 needs to be removed. By pulling the collection frame 20, it is disengaged from the ball bearing 19 and pulled out of the outer casing 13. Then, the dust is emptied and the collection frame 20 is inserted back into the outer casing 13. Initially, the collection frame 20 compresses the ball bearing 19, causing the sliding frame 18 to compress the second spring 17. When the collection frame 20 slides to the bottom, the second spring 17 will instantly push the sliding frame 18, causing the ball bearing 19 to be locked outside the collection frame 20, thus stabilizing the collection frame 20. At this point, it can be used again. The operation is convenient, time-saving, and labor-saving.
