A branch training structure for sweet cherry cultivation

Abstract

This utility model discloses a branch traction structure for sweet cherry planting, relating to the field of cherry tree planting technology. It includes a fixed base, a rotating seat mounted on the upper surface of the fixed base, a telescopic cylinder rotatably mounted on the inner surface of the rotating seat, and an extension rod slidably mounted on the upper surface of the telescopic cylinder. Compared with existing ordinary cherry tree branch pulling devices, this branch traction structure for sweet cherry planting, through the setting of a tension spring, can buffer the tension on the branch when the branch is fixed using a traction frame, especially in strong winds, by stretching the tension spring, thus preventing damage to the branch due to excessive pulling force. The threaded groove allows control of the rotating pressure sleeve to move along the threaded groove, adjusting the tension threshold of the tension spring, ensuring that the branch is stretched and decompressed only after receiving a certain amount of tension, preventing slight tension from causing the branch to sway and affecting the traction effect.

Description

Technical Field

[0001] This utility model relates to the field of cherry tree planting technology, specifically a branch traction structure for planting large cherries. Background Technology

[0002] The purpose of branch training is to open up the angle and direction of branches or main branches, which is beneficial for expanding the canopy, accelerating tree shaping, improving ventilation and light penetration, regulating the types, transport and distribution of nutrients and endogenous hormones, moderating tree or branch vigor, promoting flowering, and advancing fruiting. Because young sweet cherry trees grow vigorously with small base angles and upright branches, branch training is necessary to open up the angle. Currently, cherry branch training uses cloth strips, with one end tied to the branch and the other end inserted into the soil using an iron rod or similar tool. The main problems with this method are the time-consuming process of tying and untying the cloth strips to the branches; and the end fixed in the soil is easily pulled out, making the fixation unreliable.

[0003] For example, patent application number 202421163476.2 discloses a cherry tree branch-pulling device. This utility model discloses a cherry tree branch-pulling device including a fixing mechanism and a telescopic mechanism. The fixing mechanism includes a housing with a strip-shaped through hole on its outer side, a sliding rod on the top of the housing, and a first pressure plate on the top of the sliding rod. This cherry tree branch-pulling device, through its fixing mechanism, firmly inserts itself into the soil, making it difficult to detach. Through its telescopic mechanism, a hook holds the cherry tree branch, and rotating the rotating sleeve moves the screw, thereby pulling the cherry tree branch. This device has a simple structure and is easy to use. However, after pulling the cherry tree branch, if strong winds occur, the pulling hook will restrict the branch, making it difficult to loosen. If the wind is too strong, the pulling force can damage the branch.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a branch training structure for sweet cherry planting. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a branch traction structure for planting sweet cherries, comprising a fixed base, a rotating seat mounted on the upper surface of the fixed base, a telescopic cylinder rotatably mounted on the inner surface of the rotating seat, an extension slide rod slidably mounted on the upper surface of the telescopic cylinder, a threaded groove provided on the upper outer surface of the extension slide rod, a rotating pressure sleeve helically mounted on the outer surface of the threaded groove, a limiting slide rod slidably mounted on the upper surface of the extension slide rod, a limiting plate provided on the upper surface of the limiting slide rod, a tension spring provided on the lower surface of the limiting plate, the tension spring and the upper surface of the rotating pressure sleeve being frictionally connected, a rotating bearing provided on the upper surface of the limiting plate, and a traction frame provided on the upper surface of the rotating bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the arrangement of a fixed base, a rotating seat, a telescopic cylinder, a fixed seat, an extension slide rod, a positioning hole, a threaded groove, a rotating pressure sleeve, a limiting slide rod, a limiting plate, a tension spring, a rotating bearing, and a traction frame, utilizes the tension spring to buffer the tension on the branches after the branches are fixed using the traction frame, preventing damage to the branches due to excessive pulling force. The threaded groove allows for control of the rotating pressure sleeve's translation along the groove, adjusting the tension threshold of the tension spring. This ensures that the branches are stretched and decompressed only after receiving a certain amount of tension, preventing slight tension from causing branch swaying and affecting the traction effect.

[0016] 2. This utility model, through the arrangement of a sliding telescopic rod, a pressure relief spring, a placement seat, a threaded rod, a rotating cover, a clamping plate, and a guide slide rod, uses a threaded rod to drive the clamping plate downwards via a helical transmission, thereby clamping and fixing the branches that have entered the traction frame, further improving stability during traction and preventing branches from loosening in windy weather. The pressure relief spring, through compression, buffers the clamping force when the downward clamping force is too large, protecting the branches. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3As shown, a branch traction structure for cherry planting includes a rotating seat 101 mounted on the upper surface of a fixed base 1, a telescopic cylinder 102 rotatably mounted on the inner surface of the rotating seat 101, an extension slide rod 104 slidably mounted on the upper surface of the telescopic cylinder 102, a threaded groove 2 on the outer surface of the upper end of the extension slide rod 104, a rotating pressure sleeve 201 spirally mounted on the outer surface of the threaded groove 2, a limiting slide rod 202 slidably mounted on the upper surface of the extension slide rod 104, and a limiting plate 203 on the upper surface of the limiting slide rod 202. This technical solution, through the setting of the threaded groove 2, allows control of the rotating pressure sleeve 201 to translate along the threaded groove 2, thereby adjusting the tension threshold of the tension spring 204. This ensures that the branch can only be stretched and decompressed after being subjected to a certain tension, preventing slight tension from causing the branch to sway and affecting the traction effect. The setting of the extension slide rod 104 allows for the adjustment of the height of the traction frame 206.

[0024] Furthermore, a tension spring 204 is provided on the lower surface of the limiting plate 203, and the tension spring 204 and the upper surface of the rotating pressure sleeve 201 are set to friction connection. With the setting of the tension spring 204, after the branch is fixed by the traction frame 206, the tension of the branch can be buffered by the tension of the tension spring 204 when the wind is too strong, so as to avoid damage to the branch caused by excessive pulling force.

[0025] Furthermore, a rotating bearing 205 is provided on the upper surface of the limiting plate 203, and a traction frame 206 is provided on the upper surface of the rotating bearing 205. With this technical solution, the rotation angle of the traction frame 206 can be controlled by the setting of the rotating bearing 205, so that the branch can be better inserted.

[0026] Furthermore, a fixing seat 103 is provided on the upper outer surface of the telescopic cylinder 102, and the fixing seat 103 is composed of a connecting rod and a pin. Multiple positioning holes 105 are provided on the outer surface of the extension slide rod 104, and the positioning holes 105 and the pin of the fixing seat 103 are slidably connected. With this technical solution, the extended extension slide rod 104 can be fixed by setting the fixing seat 103.

[0027] Figure 4 As shown, a sliding telescopic rod 3 is provided on the bottom surface of the traction frame 206, and a pressure relief spring 301 is provided on the outer surface of the sliding telescopic rod 3. A placement seat 302 is provided on the upper surface of the sliding telescopic rod 3, and the placement seat 302 is made of rubber material. In this technical solution, by setting the pressure relief spring 301, the pressure relief spring 301 can buffer the clamping force of the clamping plate 305 when the downward clamping force of the clamping plate 305 is too large, thereby protecting the branches.

[0028] Furthermore, a threaded rod 303 is spirally installed on the upper surface of the traction frame 206, and a rotating cover 304 is provided on the upper surface of the threaded rod 303. A clamping plate 305 is provided on the lower surface of the threaded rod 303, and the clamping plate 305 is arc-shaped. With this technical solution, the threaded rod 303 can drive the clamping plate 305 to move downward through the spiral transmission, thereby clamping and fixing the branches that have entered the traction frame 206, further improving the stability during traction, and also preventing the branches from loosening in windy weather.

[0029] Furthermore, guide slide rods 306 are provided on both sides of the upper surface of the clamping plate 305, and the guide slide rods 306 and the traction frame 206 are connected by a sliding through connection. This technical solution can limit the sliding direction of the clamping plate 305 by setting the guide slide rods 306, and prevent it from deviating when it moves.

[0030] Working principle: When using this cherry tree branch traction structure, firstly, at the orchard site, firmly install the fixed base 1 in the predetermined position to ensure its solid foundation. Then, slowly pull out the extension slide rod 104 from the telescopic cylinder 102, adjust it to the appropriate length according to actual needs, and then accurately insert the pin in the fixed base 103 into the positioning hole 105 to reliably fix the extension slide rod 104.

[0031] After completing the above operations, the traction frame 206 is flexibly rotated using the rotating seat 101 to bring it close to the cherry branch. Next, the angle of the traction frame 206 is finely adjusted using the rotating bearing 205 to smoothly insert the branch. At this point, rotating the rotating cover 304 clockwise causes the threaded rod 303 to spiral downwards, causing the clamping plate 305 to slide down the guide slide rod 306 at a uniform speed, gradually pressing and holding the branch until it is firmly fixed to the upper surface of the placement seat 302, thus successfully completing the branch clamping and traction process.

[0032] It is worth mentioning that during the pressing down of the clamping plate 305, if the clamping force is too great, the pressure relief spring 301 will respond quickly, compressing and causing the sliding telescopic rod 3 to contract, thereby effectively buffering the pressure and protecting the branches on the surface of the placement seat 302 from damage. In severe weather conditions such as strong winds, the traction frame 206 plays a crucial role, firmly fixing the branches and suppressing their large swaying. Once the pulling force exceeds the safety threshold, the tension spring 204 stretches and causes the sliding telescopic rod 3 to automatically extend, appropriately lengthening the position of the traction frame 206 to dissipate excessive tension, minimizing the risk of branch damage and providing stable protection for the growth of the cherry branches. This is the working principle of this cherry tree branch traction structure.
