Description

Technical Field

[0001] This utility model relates to the field of branch pulling technology, and in particular to a branch pulling device for greenhouse planting. Background Technology

[0002] In the field of greenhouse cultivation, branch training is a key agricultural operation that affects crop growth and fruit quality. Through proper branch training, the ventilation and light conditions of crop plants can be effectively improved, promoting efficient photosynthesis. It can also regulate the distribution of nutrients within the plant, guiding nutrients to where they are needed, thereby increasing the yield and quality of the fruit.

[0003] Existing devices typically use fixed-length branch pullers, which cannot adjust the tension according to the needs of different crops and different growth stages. For newly planted seedlings, whose branches are slender and fragile, the fixed-tension branch pullers are prone to breakage due to excessive tension. On the other hand, for the branches of vigorous mature plants, the fixed tension may be insufficient to achieve the ideal branch pulling angle, making it difficult to effectively improve the ventilation and light penetration of the plants. Therefore, improvements are needed to address these issues. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 This utility model discloses a branch-pulling device for greenhouse planting, comprising a V-shaped block 1, a first column 2 fixedly connected to one corner of the top surface of the V-shaped block 1, multiple nested blocks 3 nested in multiple levels on one side wall of the V-shaped block 1, a vertical block 4 fixedly connected to the end of the farthest nested block 3, two branch-clamping columns 5 symmetrically arranged on one side of the vertical block 4, and a movable block 6 provided on the other side wall of the V-shaped block 1, with a second column 7 on the top surface of the movable block 6; the V-shaped block 1 is injection molded from high-strength PP plastic, possessing good toughness and weather resistance; the nested blocks 3 are made of ABS plastic with a smooth surface; this structure, through the cooperation of the multi-level nested blocks 3 and the branch-clamping columns 5, facilitates the adjustment of the branch-pulling position, improves the flexibility of the branch-pulling range, and thus realizes the multi-angle branch-pulling function; the V-shaped block Two first spring grooves are symmetrically opened on the opposite surface of the movable block 6. A first spring 8 is installed in the first spring groove. One end of the first spring 8 is fixedly connected to the movable block 6. A limiting cylinder 9 is sleeved on the first spring 8. The limiting cylinder 9 is made of polyoxymethylene (POM) material, which has good wear resistance. Through the cooperation of the first spring 8 and the limiting cylinder 9, a stable clamping force is easily provided, which improves the stability of the branch clamping and thus realizes a reliable branch fixing function. A limiting ring groove is opened at the first spring groove of the V-block 1. Part of the cylinder body of the limiting cylinder 9 is located in the limiting ring groove. One end of the limiting cylinder 9 is fixedly connected to the movable block 6. This structure, through the guiding effect of the limiting ring groove on the limiting cylinder 9, facilitates the linear extension and contraction of the first spring 8, improves the stability of the spring movement, and thus realizes a stable elastic force transmission function.

[0020] In this utility model, multiple nested blocks 3 are fixedly connected to the inner wall of the nested block 3 of the next higher level with limiting blocks 10. A second spring groove is opened on the top surface of the limiting block 10, and a second spring 11 is installed in the second spring groove. A locking steel ball 12 is fixedly connected to one end of the second spring 11. The locking steel ball 12 is made of GCr15 bearing steel. The limiting block 10 is made of ABS plastic and is integrally injection molded with the nested block 3. Through the cooperation of the limiting block 10 and the locking steel ball 12, it is easy to fix the stretching length of the nested block 3, improve the accuracy of the pull distance adjustment, and thus realize the precise pull positioning function. A through hole for the locking steel ball 12 to pop out is opened at one end of the top surface of each nested block 3. The through hole is along the nested block. Blocks 3 are spaced apart along their length. This structure, through the cooperation of spaced through holes and locking steel balls 12, facilitates multi-level locking of nested blocks 3, improves the adjustment range of the branch pulling device, and thus realizes a wide range of branch pulling operations. The upper ends of the first column 2 and the second column 7 are inclined in different directions. The first column 2 is inclined away from the clamping column 5, and the second column 7 is inclined closer to the clamping column 5. Both the first column 2 and the second column 7 are made of glass fiber reinforced plastic, which is strong and lightweight. The reverse inclination design of the first column 2 and the second column 7 facilitates the formation of a stable clamping structure, improves the reliability of branch clamping, and thus realizes a stable branch fixing function.

[0021] Working Principle: When using this invention, the V-block 1 is placed in a suitable position, and the branch to be pulled is initially clamped by the first column 2 and the second column 7. The first column 2 is inclined away from the clamping column 5, and the second column 7 is inclined towards the clamping column 5, providing a foundation for branch clamping. At this time, the first spring 8 installed in the first spring groove on the opposite side of the V-block 1 and the movable block 6 plays a crucial role. The elastic force of the first spring 8 pushes the movable block 6, causing the second column 7 to move closer to the first column 2, thereby enhancing the clamping force on the branch and achieving a stable clamping of the branch, laying the foundation for subsequent branch pulling. The limiting cylinder 9 outside the first spring 8 is located within the limiting ring groove of the V-block 1, ensuring that the first spring 8 extends and retracts in a straight line, avoiding deviation and ensuring stable clamping force. If adjustment is needed... The entire branch-pulling range can be adjusted by pulling the nested block 3. The nested block 3 is nested in multiple levels on one side wall of the V-shaped block 1. During the pulling process, the limiting block 10 slides on the inner wall of the nested block 3 to limit the maximum stretching distance and prevent the nested block 3 from coming out. At the same time, the second spring 11 in the second spring groove pushes the locking steel ball 12 out. When the locking steel ball 12 is inserted into the through holes at different positions on the top surface of the nested block 3, it can fix the stretching length of the nested block 3, realizing multi-level adjustment of the branch-pulling range. When pulling the branch, the branch generates a reaction force on the first column 2 and the second column 7. This force is transmitted to the V-shaped block 1 through the nested block 3. The first spring 8 adapts to the force changes of the branch through its own elasticity, avoiding damage to the branch due to excessive clamping. At the same time, it can maintain a stable clamping effect when the branch has a slight displacement. Thus, the device is used.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
