[0001] The utility model relates to the technical field of fruit tree branch pullers, in particular to an apricot and plum fruit tree branch puller with a branch and leaf protection mechanism. Background Art

[0002] In the process of planting apricot and plum fruit trees, in order to cultivate the tree skeleton structure, reasonably distribute the branches in space, improve light and ventilation conditions, change the branch polarity, adjust the branch strength, promote or inhibit the branch growth, and adjust the contradiction between fruit tree growth and fruiting, it is generally necessary to pull the branches of the fruit tree branches. Therefore, a fruit tree branch puller is used. It is one of the fruit tree shaping methods. The fruit tree branch puller can artificially change the growth angle and distribution direction of the branches. It also plays a very important role in opening the angle in time. Nutrients are easily accumulated in the branches, making the buds fuller and promoting early flowering.

[0003] The above-mentioned and existing related technologies often have the following defects: when pulling branches of apricot and plum fruit trees, the hanging method is generally adopted, and hanging is to tie a rope to the branch and pull the branch by counterweighting the other end of the rope or tying it to the trunk. Therefore, personnel must prevent the pulling rope from embedding into the wood of the branch, and add pads when pulling the branch. For example, hard contact may easily cause the contact position to embed and cause the branch or trunk to peel, affecting the growth of the tree. At the same time, the pulling angle of the branch must also be adjusted. When inexperienced personnel implement it, it is easy to make the pulling angle insufficient or too large, resulting in insufficient differentiation of flower buds or fragile and easy breakage of branches after fruiting.

[0004] For this reason, we propose an apricot and plum fruit tree branch puller with a branch and leaf protection mechanism. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 4The utility model provides a technical solution: a branch puller for apricot and plum fruit trees with a branch and leaf protection mechanism, comprising a sleeve 1, one side of the sleeve 1 is threadedly connected with two screw rods 2, the arc surfaces of the two screw rods 2 are threadedly connected with a connecting sleeve 3, the connecting sleeve 3 is located on one side of the sleeve 1, the connecting sleeve 3 is fixedly connected with a circular plate 4 on the side away from the sleeve 1, the circular plate 4 is rotatably connected with a rotating plate 5 on the side away from the connecting sleeve 3, the rotating plate 5 is fixedly connected with a fixing frame 6 on the side away from the circular plate 4, the inner wall of the fixing frame 6 is slidably connected with a sliding rod 7, and the lower end of the sliding rod 7 is fixedly connected with an arc sleeve 8, so as to achieve the effect of protecting the branches and trunks of apricot and plum fruit trees while pulling the branches, thereby avoiding the problem that the pulling rope is easily embedded in the wood part of the branch when hanging and pulling the branch, causing detachment and affecting growth, and inexperienced personnel are not easy to adjust the angle of the branch pulling branch, resulting in insufficient differentiation of flower buds or fragile and easy breakage of branches after fruiting.

[0028] like Figure 2 and Figure 3 As shown, the inner wall of the fixed frame 6 is rotatably connected with a driving rod 9, and the lower end of the driving rod 9 is rotatably connected with the arc sleeve 8. The rotating driving rod 9 drives the arc sleeve 8 to move through the fixed frame 6, and the driving rod 9 plays a role in adjusting the angles of the branch pulling at different times. A plurality of air holes 10 are provided on the surface of the arc sleeve 8. The arc sleeve 8 is a plastic sleeve. With the help of the plastic arc sleeve 8 with the air holes 10, the effect of being breathable while clamping thicker branches and limiting thinner branches can be achieved. A filling pad 11 is fixedly connected to the inner wall of the connecting sleeve 3. The filling pad 11 is a sponge pad. The connecting sleeve 3 drives the filling pad 11 to fit with the main branch, and the filling pad 11 fills the concave and convex gaps on the surface of the main branch to improve the limiting strength of the connecting sleeve 3.

[0029] like Figure 2 and Figure 3 as well as Figure 4 As shown, the upper surface of the fixed frame 6 is fixedly connected with a connecting frame 12, and the inner wall of the connecting frame 12 is rotatably connected with a lever 13, and the lever 13 is located between the arc sleeve 8 and the connecting sleeve 3. The arc sleeve 8 presses the branch to make the bent part fit with the lever 13, and the lever 13 supports the bent part, thereby improving the effect of the arc sleeve 8 pulling the branch. The fixed frame 6 is an L-shaped frame, and the cross-section of the lever 13 is semicircular. With the help of the lever 13 with a semicircular cross-section, when the fixed frame 6 is moved out, the lever 13 can be rotated to make its own arc surface separate from the branch and provide a certain space. A plurality of rubber U-shaped sleeves 14 are evenly fixedly connected to one side of the circular plate 4 close to the rotating plate 5, and a clamping block 15 is fixedly connected to the arc surface of the rotating plate 5. The surface of the clamping block 15 is slidably connected to the inner walls of the plurality of rubber U-shaped sleeves 14, and the rotating plate 5 drives the clamping block 15 to slide from the inner walls of the plurality of rubber U-shaped sleeves 14, and the rubber U-shaped sleeve 14 provides a certain damping effect so that the rotating plate 5 remains stable when it is not rotated with great force.

[0030] Working principle: When the branches of the apricot and plum fruit trees need to be pulled, first place the clamping sleeve 1 on the arc surface of the main rod, then move the connecting sleeve 3 to slide from the end of the branch to be pulled. At this time, the connecting sleeve 3 is above the branch, and the branch is located between the lever 13 and the fixed frame 6, until the connecting sleeve 3 fits with the clamping sleeve 1, and the filling pad 11 fits with the arc surface of the main rod through the connecting sleeve 3. The filling pad 11 fills the concave and convex gaps on the surface of the main branch to improve the limiting strength of the connecting sleeve 3, and then rotates the screw 2 through The clamping sleeve 1 is inserted into the connecting sleeve 3, so that the connecting sleeve 3 and the clamping sleeve 1 are limited on the main rod, and then the fixing frame 6 is rotated, and the rotating plate 5 is rotated from one side of the rotating plate 5 through the fixing frame 6, and the clamping block 15 slides through the rubber U-shaped sleeve 14 through the rotating plate 5. The rubber U-shaped sleeve 14 provides a certain damping effect so that the rotating plate 5 remains stable when it is not rotated by a large force. After rotating to a certain angle, the L-shaped fixing frame 6 drives the arc sleeve 8 to squeeze the branches with the help of the sliding rod 7, and the plastic arc sleeve 8 is stretched to be sleeved on the branch circle. The arc sleeve 8 and the branch trunk are connected by the air vents 10, and the arc sleeve 8 and the branch trunk are connected by the air vents 10, so that the branch trunk is squeezed and bent, and the bent position is supported by the arc surface of the lever 13. The lever 13 supports the bent part to improve the effect of the arc sleeve 8 on pulling the branch, so that when the fixed frame 6 is moved out, the lever 13 can be rotated to separate its own arc surface from the branch trunk and provide a certain space. At this time, the branch pulling angle of the L-shaped fixed frame 6 is small, so it is better adapted to the branches in the initial stage of pulling the branch. After pulling the branch for a certain period of time, the rotating driving rod 9 moves through the fixed frame 6, and the driving rod 9 plays a role in adjusting the angles of the branches in different periods. The arc sleeve 8 squeezes the branches and pulls the branches again through the driving rod 9, thereby further increasing the pulling angle of the branches, so that the branches that are pulled by a small angle in the early stage are better adapted to the pulling of branches at a large angle in the later stage, and the large area of the arc sleeve 8 is in contact with the branches, so that the structural friction during the pulling process is effectively avoided and the branches are stuck in the branches, thereby playing a certain role in protecting the branches.
