Technical Field

[0001] The utility model relates to a shaping device, in particular to a shaping device used for branches of trees in agriculture, forestry and gardening. Background Art

[0002] In the process of implementing the dwarfing and dense planting technology of fruit trees, as the fruit trees grow, especially when the fruit trees reach the two-year-old growth stage, the application of the original branching device in branch pulling has shown obvious limitations. Although there are some metal branch pullers on the market, such as "mountain" shape, "bow" shape and "S" shape, the metal material has the problem of easy rust. The rusty water formed after rain erosion may not only pollute the fruit trees and induce diseases, but also in orchard operations, the existing branch pullers are easy to fall off after being fixed, especially the metal branch pullers are potential threats to the mechanical equipment such as weeders and rotary tillers used in the orchard, which may cause damage to the mechanical teeth and even splash to injure the fruit trees or staff. Therefore, the development of a new branch puller to meet the needs of dwarfing fruit tree growth management has become an urgent problem to be solved in the industry. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The embodiments in the basic utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] according to Figure 1 and Figure 2 As shown, a shaper for branches of agricultural, forestry and horticultural trees comprises a main support 4 and side supports 5 arranged at both ends of the main support 4, the main support 4 is connected to the middle support 3, and the middle support 3 is located between the side supports 5, and a limiting portion is arranged on the side support 5, the middle support 3 is curved so that the side support 5 cooperates with the inner curved surface of the middle support 3 to clamp the branches, thereby increasing the clamping force to prevent loosening, and the limiting portion has an anti-falling blocking function for the branches, thereby ensuring the fixing effect of the branches, and the curved structure of the middle support 3 has the effect of increasing the clamping force and preventing loosening of the branches, wherein an 8 cm long branch press is suitable for branches with a tree diameter of 0.8 cm, a 10 cm long branch press is suitable for branches with a tree diameter of 1 cm, and a 13 cm long branch press is suitable for branches with a tree diameter of 1.3 cm. The use of branch presses of different specifications can accurately match branches of different diameters, achieve efficient branch pressing, and the branch pressing angle is scientific and appropriate.

[0023] The middle support 3 adopts a flat structure. This implementation method can make the middle support 3 fit the arc surface of the branch, flatten the branch, reduce the formation of branches on the back after pressing the branch, and reduce secondary operations.

[0024] The connection position between the middle support 3 and the main support 4, and the connection position between the side support 5 and the main support 4 are located in the same straight line. By adopting the above-mentioned implementation mode, the branches are clamped by the torque between the middle support 3, the side support 5 and the main support 4, and this method can obtain the maximum clamping force, greatly reducing the risk of detachment.

[0025] The main support 4 is integrally formed with the middle support 3 and the side support 5, and the shaper is made of modified engineering plastic injection molding as a whole. This material is resistant to aging, chemicals and wear, has a certain flame retardancy and is easy to process, which significantly extends the service life and reduces the cost of orchard management. Discarded branch pressers can still be 100% recycled and reused to reduce environmental pollution. Compared with traditional metal branch pullers, the branch pressers using this implementation method can maintain sufficient strength while greatly reducing the risk of falling off, thereby improving the safety of orchard operations.

[0026] Reinforcement ribs 2 are respectively arranged at the connection between the main support 4 and the middle support 3 and the side support 5. The reinforcement ribs 2 can improve the overall strength of the shaper and ensure the stability of the middle support 3 and the side support 5.

[0027] according to Figure 3 As shown, the length of the middle support 3 is greater than the length of the side support 5. It is further preferred that the middle support 3 is 1.5 times the length of the side support 5. With the above embodiment, the middle support 3 can be pressed onto the branch and then the side support 5 can rotate with the main support 4 as the rotation axis so that the side support 5 cooperates with the middle support 3 to clamp the branch.

[0028] according to Figure 4 , Figure 5 and Figure 6 As shown, a limiting portion is axially slidably provided on the side support 5, and the best limiting effect is obtained by adjusting the position of the limiting portion, thereby preventing the branch from moving between the side support 5 and the middle support 3 after clamping, and further playing an anti-slip effect.

[0029] The limiting portion includes a moving plate 10 and a limiting protrusion 1 radially arranged on the moving plate 10. The moving plate 10 is located in a moving cavity 9 axially opened in the side support 5 and moves axially. The limiting protrusion 1 extends to the outside through a moving groove 7 axially opened on the side support 5, and the limiting protrusion 1 moves axially in the moving groove 7. The moving plate 10 is connected to the tightening rope 6 to pull the moving plate 10. A pull rope channel 8 connected to the moving cavity 9 is axially opened in the side support 5. The tightening rope 6 is led out to the outside through the pull rope channel 8. By pulling the tightening rope 6, the limiting protrusion 1 is pressed against the branch to limit the movement of the branch, so as to prevent the shaper from falling off after being fixed. The tightening rope 6 can be tied to the main support 4 or connected to each other for tightening and fixing.

[0030] Working principle: The side support 5 and the middle support 3 are rotated with the main support 4 as the rotation axis, and the side support 5 and the middle support 3 turn in opposite directions. At the same time, the tree branches are inserted between the side support 5 and the middle support 3. Under the action of torque, the side support 5 and the middle support 3 clamp the tree branches, and the limit part restricts the tree branches from falling off from the side support 5 and the middle support 3.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
