Description

Technical Field

[0001] The utility model relates to the technical field of nursery stock planting, in particular to a nursery stock planting straightening device. Background Technique

[0002] In order to improve the greening effect in places such as communities, commercial parks, and roadsides, a large number of trees are usually planted at designated positions. Especially now that people's living environment is constantly improving, the greening of gardens is particularly important. When planting trees, some directly plant saplings, and some directly transplant finished trees with a certain tree age. However, there is a problem in both of the above two situations, that is, the tree roots have not fully grown in the new environment and are very prone to tilting or toppling. Especially in strong wind weather, the stability of nursery stocks is relatively poor. Therefore, a straightening device is needed to support the nursery stocks. The existing straightening devices include the form of using wooden brackets, but the wooden brackets are prone to breakage, or the form of using a clamp in cooperation with a four-legged metal frame. The plastic clamp is also prone to breakage. When using the metal clamp, since the tree is not a standard cylinder, the fit with the tree is poor, and when supporting tree trunks of different sizes, gaps are likely to occur in the middle, affecting the support strength. Content of the Utility Model

[0003] In order to solve the technical problems existing in the above background technique, the utility model provides a nursery stock planting straightening device.

[0004] The technical solution of the utility model is as follows:

[0005] A nursery stock planting straightening device includes two arc-shaped hoop frames, and both ends of the two are connected to each other through fixing bolts. Brackets are hinged at the connection positions at both ends and on the side surfaces of the arc-shaped hoop frames;

[0006] Two top-tightening screws are respectively arranged through the side surfaces of the two arc-shaped hoop frames, and the top-tightening screws are arranged at intervals with the brackets. The top-tightening screws are fixed to the arc-shaped hoop frames through two nuts arranged inside and outside the arc-shaped hoop frames;

[0007] The top end of the top-tightening screw is hinged with an arc-shaped top plate, and the arc-shaped top plate is located inside the arc-shaped hoop frame. Both the arc-shaped top plate and the arc-shaped hoop frame are bent in the direction close to the bracket, and an arc-shaped top pad is installed on the outer side of the arc-shaped top plate.

[0008] The installation method of the arc-shaped top pad is that an arc-shaped groove is opened on the end surface of the arc-shaped top plate close to the top-tightening screw, and the arc-shaped top pad includes symmetrically arranged fastening parts, and the fastening parts are buckled with the upper and lower end surfaces of the arc-shaped groove. The fastening parts are connected with a top-tightening part extending to the other end surface of the arc-shaped top plate.

[0009] To facilitate the buckling and disassembly of the arc-shaped top pad and the arc-shaped groove, the arc-shaped top pad is integrally made of an elastic material.

[0010] To improve the stability of the arc-shaped top pad and the compactness of the overall structure, the length of the arc-shaped top pad is not greater than the length of the arc-shaped top plate.

[0011] To increase the friction between the arc-shaped top pad and the tree when they are fixed to improve stability, multiple anti-slip stripes are provided on the end face of the tightening part away from the arc-shaped top plate, and the anti-slip stripes are arranged vertically.

[0012] The hinged manner of the arc-shaped top plate is that a hinge seat is installed in the arc-shaped groove, and the tightening screw is hinged to the hinge seat through a rotating shaft.

[0013] To improve the rotational freedom of the arc-shaped top plate so that it can fit more closely to the uneven tree trunk, a ball hinge seat is provided in the arc-shaped groove, and a fixing bead hinged to the ball hinge seat is fixedly connected to the end of the tightening screw.

[0014] To facilitate the adjustment of the height of the bracket so that the entire straightening device can straighten seedlings of various different heights, the bracket includes a hinge tube hinged to the connection position of the arc-shaped hoop and the side of the arc-shaped hoop, and a telescopic column is slidably arranged at the bottom of the hinge block. A plurality of positioning holes are provided on the outer edge surface of the hinge tube, and the hinge tube and the telescopic column are fixed by passing a positioning pin through the positioning holes.

[0015] To improve the stability of the straightening device fixed to the ground, the bottom of the telescopic column is hinged with a fixing plate, and a plurality of insertion columns are installed at the bottom of the fixing plate.

[0016] The beneficial effects of the present utility model are as follows: The present utility model is a seedling planting straightening device. Firstly, the arc-shaped hoop connected by two fixing bolts, combined with four hinged brackets, can be sleeved on the outer edge surface of the seedling and supported on the ground through the brackets to achieve the supporting effect on the seedling. Secondly, through the four tightening screws installed through the outer edge surface of the arc-shaped hoop, combined with the arc-shaped top block and the arc-shaped top pad, when the arc-shaped hoop supports the seedling, the contact surface is arc-shaped, and the distance between each tightening screw and the seedling can be freely adjusted, so that multiple arc-shaped top blocks and arc-shaped top pads can respectively be tightened and adapted to the non-standard cylindrical seedlings, avoiding the situation where the traditional clamp cannot be adapted to the seedlings, and adapting to the support of trees of various different thicknesses. Finally, the hinged connection between the arc-shaped top plate and the tightening screw enables the arc-shaped top block and the arc-shaped top pad to rotate to adapt to the inclined end face when the end face of the seedling is inclined, making the arc-shaped top pad fit more closely to the seedling and improving the stability of the support.

[0029] Embodiment

[0030] As mentioned in the background art, after the seedlings are planted or transplanted, the roots are not fully grown in the new environment and are prone to tilt or fall. A straightening device is needed to support the seedlings to ensure their relatively upright state. However, the inventor found in daily observations that the existing straightening devices are mostly made of wooden sticks, which are very easy to break, or use clamps in combination with four-legged metal frames. High requirements are imposed on the size of the clamps, which need to be customized according to the size of the seedlings, and there are also many defects in the clamps. Therefore, the inventor improved the existing straightening device and designed a new type of straightening device, which will be specifically described below with reference to the drawings.

[0031] This embodiment provides a device for straightening seedlings during planting. Refer to Figure 1 , which includes two arc-shaped hoop frames 1, and both ends of the two are connected to each other by fixing bolts 2. Ear plates are provided at both ends of the two arc-shaped hoop frames 1. When connecting the arc-shaped hoop frames 1, the ear plates are butted against each other, and the fixing bolts 2 are passed through and fixed. Brackets 3 are hinged at both ends of the connection position and on the side surface of the arc-shaped hoop frame 1. The connection position is where the brackets 3 are hinged between the ear plates of the two arc-shaped hoop frames 1, and can be rotatably connected to the middle fixing bolt 2, while on the side surface of the arc-shaped hoop frame 1, they are hinged by means of a hinge base, which facilitates adjusting the angle of the bracket 3 to adapt to different installation positions.

[0032] In this embodiment, combined with Figure 1 , the bracket 3 includes a hinge tube 31 hinged to the connection position of the arc-shaped hoop frame 1 and the side surface of the arc-shaped hoop frame 1. And a telescopic column 32 is slidably arranged at the bottom end of the hinge block. The telescopic column 32 can extend or retract along the extension direction of the hinge tube 31. A plurality of positioning holes 33 are provided on the outer edge surface of the hinge tube 31. Similarly, positioning holes 33 are provided at the top end of the telescopic column 32. The hinge tube 31 and the telescopic column 32 are fixed by passing a positioning pin 34 through the positioning holes 33. When supporting different seedlings, by adjusting the length of the telescopic column 32 extended, the positioning holes 33 of the telescopic column 32 are aligned with the positioning holes 33 at different heights of the hinge tube 31, and the positioning pin 34 is inserted and fixed, realizing the adjustment of the support height.

[0033] Moreover, a fixing plate 35 is hinged at the bottom of the telescopic column 32, and a plurality of insertion columns 36 are installed at the bottom of the fixing plate 35. By providing the fixing plate 35 and the insertion columns 36, the positioning plate can be closely attached to the ground, and the insertion columns 36 are inserted into the ground to complete the fixation of the bracket 3 to the ground.

[0034] As the main technical point of this solution, combined with Figure 2 and Figure 3, two top - tightening screws 4 are respectively arranged through the sides of the two arc - shaped hoop frames 1, that is, four are arranged on the sides of the two arc - shaped hoop frames 1. The top - tightening screws 4 are arranged at intervals with the bracket 3. And in order to improve the fixing effect, the connection line of the two opposite top - tightening screws 4 is perpendicular to the connection lines of the other two opposite ones. The top - tightening screw 4 is fixed to it by two nuts 5 arranged inside and outside the arc - shaped hoop frame 1. When the two nuts 5 are fixed, they are tightened until they abut against the inner and outer sides of the arc - shaped hoop frame 1. And, the top end of the top - tightening screw 4 is hinged with an arc - shaped top plate 6, which is located inside the arc - shaped hoop frame 1. Moreover, in order to be convenient for matching with the seedlings, both the arc - shaped top plate 6 and the arc - shaped hoop frame 1 are bent in the direction close to the bracket 3, so that the side of the arc - shaped top plate 6 close to the seedlings is concave. And an arc - shaped top pad 7 is installed on the outside of the arc - shaped top plate 6. Installing the arc - shaped top pad 7 can be used to protect the outer skin of the seedlings and prevent the arc - shaped top plate 6 from damaging the tree trunk. When carrying out the support, the two arc - shaped hoop frames 1 are sleeved on the outside of the tree trunk, and the fixing bolts 2 are tightened to fix the two. Secondly, the top - tightening screws 4 are pushed in turn to drive the arc - shaped top pad 7 to abut against the tree trunk, the external nut 5 is tightened to drive the arc - shaped top pad 7 to be tightly pressed against the tree trunk, and then the internal nut 5 is tightened to fix the top - tightening screw 4.

[0035] Moreover, specifically, an arc - shaped groove 8 is opened on the end face of the arc - shaped top plate 6 close to the top - tightening screw 4. As Figure 4 shown, the size of the arc - shaped groove 8 is smaller than the end face of the arc - shaped top plate 6 where it is located. The length of the arc - shaped groove 8 is the same as the length of the arc - shaped top pad 7, and the whole is located in the middle position of this end face. Combining Figure 5 , and the arc - shaped top pad 7 includes symmetrically arranged fastening parts 71. The fastening parts 71 are concave into the arc - shaped groove 8, which can limit the whole arc - shaped top pad 7 and realize the fixation with the arc - shaped top plate 6 without using other components, which is convenient and fast. And the fastening parts 71 are buckled with the upper and lower end faces of the arc - shaped groove 8. The fastening parts 71 are connected with a top - tightening part 72 extending to the other end face of the arc - shaped top plate 6. The top - tightening part 72 is located on the end face of the arc - shaped top plate 6 far from the arc - shaped groove 8, and it contacts and presses against the tree trunk during support. And it is made of an elastic material, rubber in this embodiment. On the one hand, it is in elastic contact with the tree trunk and will not damage the tree trunk. On the other hand, it is elastic as a whole and can be fastened with the arc - shaped top plate 6.

[0036] On the basis of the above structure, the length of the arc - shaped top pad 7 is not greater than the length of the arc - shaped top plate 6, but the width of the arc - shaped top pad 7 is the same as that of the arc - shaped groove 8, so that the fastening parts 71 of the arc - shaped top pad 7 can be tightly buckled in the arc - shaped groove 8, making the whole arc - shaped top pad 7 more stable and making the structure of the arc - shaped top plate 6 and the arc - shaped top pad 7 more compact.

[0037] It should be noted that a plurality of anti-slip stripes 73 are provided on the end surface of the pressing part 72 away from the arc-shaped top plate 6, and the anti-slip stripes 73 are arranged vertically. The vertically arranged anti-slip stripes 73 enable the pressing part 72 to be adapted to the vertical texture of the tree trunk when pressing against the tree trunk, so that one or more anti-slip stripes 73 enter between the vertical textures, and the anti-slip stripes 73 are limited by the characteristics of the tree trunk itself, further improving the stability of the arc-shaped top pad 7.

[0038] Moreover, another main design point of this solution is the hinge connection between the arc-shaped top plate 6 and the pressing screw 4. And a small part of the front end of the pressing screw 4 at the hinge position is not provided with threads and is a smooth part. The first hinge connection method is as follows. Figure 2 and Figure 6 , the cross-sectional view method is Figure 2 the cross-section consistent with the extending direction of the pressing screw 4 and passing through the center line of the pressing screw 4 in this direction. An articulated seat 9 is installed in the arc-shaped groove 8, and the pressing screw 4 is hinged to the articulated seat 9 through a rotating shaft 10. When the pressing screw 4 drives the arc-shaped top plate 6 to move towards the tree trunk until the arc-shaped top pad 7 abuts against the tree trunk, at the uneven position of the tree trunk, the arc-shaped top plate 6 can rotate up and down around the hinge block, so that the arc-shaped top pad 7 fits the tree trunk. The second hinge connection method is as follows. Figure 6 and Figure 7 , a ball hinge seat 11 is arranged in the arc-shaped groove 8, and a fixed bead 12 hinged to the ball hinge seat 11 is fixedly connected to the end of the pressing screw 4. Through the arrangement of the ball hinge seat 11 and the ball hinge seat 11, the rotation freedom degree of the arc-shaped top plate 6 is improved, so that it can not only rotate in the vertical direction, but also rotate universally around the ball hinge seat 11, so that after the arc-shaped top pad 7 abuts against the tree trunk, it can rotate universally, more adapting to the uneven tree trunk surface.
