Technical Field

[0001] This utility model relates to the technical field of seedling breeding devices, specifically an adjustable seedling breeding device. Background Technology

[0002] Seedling breeding equipment includes seedling support devices, which are specialized equipment used to provide physical support during the growth of seedlings. Their main functions include fixing the seedling trunk, adjusting the height, and preventing wind and lodging. They are mainly used in landscaping, fruit tree cultivation, and seedling breeding bases, and are especially suitable for the early growth stages of tall seedlings or fragile varieties.

[0003] Chinese patent CN219844237U discloses an adjustable seedling breeding device, including a seedling frame body. The seedling frame body has a vertical box with an open top on one side. Each side of the vertical box has a first sliding groove, and each first sliding groove is connected to a slider. The sliders are all fixedly connected to a vertical rod. The vertical rod has slots on both sides near its lower end. The advantages of this invention are: the first sliding groove and sliders facilitate control of the overall height of the seedling frame; the second sliding groove and sliding plate facilitate adjustment of the positions of several retaining rings. This allows for support and positioning of seedlings at different heights and positions on the seedling frame body, increasing the overall vertical growth capacity of the seedlings, preventing them from tipping over, and supporting multiple trees simultaneously, thus improving the practicality of the support frame, reducing worker labor intensity, increasing work efficiency, and improving the overall growth quality of the seedlings.

[0004] The aforementioned device can support multiple seedlings, but the height of the seedlings will continuously change during growth. When the existing device clamps the seedlings, it cannot keep up with the growth rate of the seedlings, and its own weight will also inhibit the growth of the seedlings. Therefore, an adjustable seedling breeding device is needed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable seedling breeding device to solve the problems of existing devices being unable to keep up with the growth rate of seedlings when providing seedling support, and the fact that the device's own weight also inhibits seedling growth.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable seedling breeding device, comprising a base, wherein a plurality of ground nails are fixedly installed on the lower part of the base, and a straightening mechanism is provided on the upper part of the base; the straightening mechanism comprises a plurality of single tubes, one end of each single tube is fixedly installed with a limiting post, and a limiting groove is opened on one side of each single tube, and two limiting seats are fixedly installed side by side on the other end of each single tube, a sliding rod is slidably installed through both limiting seats, a positioning seat is fixedly installed between the two sliding rods, and a support spring is fixedly installed between the two sliding rods and the limiting seats.

[0007] Preferably, the plurality of single tubes are nested and slidably connected to each other, and the inner diameter of the plurality of single tubes increases sequentially, and the limiting post is embedded and slidably installed in the limiting groove.

[0008] Preferably, a plurality of semi-circular rubber strips are fixedly installed side by side on one side of the positioning seat, and the semi-circular rubber strips protrude from the positioning seat.

[0009] Preferably, one end of the single tube is provided with a clamping mechanism, the clamping mechanism including an extension tube, the extension tube being slidably installed inside the single tube, and a limit post being fixedly installed at one end of the extension tube, and a shaped tube being fixedly installed at the other end of the extension tube, a support seat being sleeved on the outside of the shaped tube, a first clamping seat being fixedly installed at one end of the support seat, a second clamping seat being rotatably installed on the first clamping seat, and rubber pads being fixedly installed on one side of both the first clamping seat and the second clamping seat, and two buffer springs being fixedly installed between the second clamping seat and the support seat.

[0010] Preferably, a limiting post is fixedly installed on one side of the extension tube, and the limiting post is adapted to the limiting groove.

[0011] Preferably, both sides of the irregular tube are provided with strip-shaped grooves, and the support base is adapted to the strip-shaped grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This is used for an adjustable seedling breeding device. A positioning seat is slidably installed at one end of a single tube. Under the action of a support spring, the positioning seat clamps the single tube to prevent it from sliding on its own. By pulling the positioning seat, the restriction on the single tube can be released, which facilitates the extension or retraction of the single tube and ensures that the device can adapt to seedlings of different heights for correction treatment.

[0014] 2) This adjustable seedling breeding device controls the support base to be located at the bottom of the irregular tube, and further controls the No. 1 clamp and No. 2 clamp to hold the seedling. When the seedling grows, the support base will be supported and moved upward along the irregular tube. When the support base is close to the top of the irregular tube, the single tube will further raise the irregular tube so that the support base is located at the bottom of the irregular tube, reducing the restriction of the device's own weight on the growth of the seedling.

Detailed Implementation

[0020] 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.

[0021] Example 1

[0022] Combination Figures 1-3An adjustable seedling breeding device includes a base 1, with several ground nails 2 fixedly installed on the lower part of the base 1, and a straightening mechanism 3 provided on the upper part of the base 1. The straightening mechanism 3 includes several single tubes 301, with a limiting post 302 fixedly installed at one end of each single tube 301, and a limiting groove 303 opened on one side of each single tube 301. Two limiting seats 304 are fixedly installed side by side at the other end of each single tube 301. A sliding rod 305 is slidably installed through each of the two limiting seats 304. A positioning seat 306 is fixedly installed between the two sliding rods 305, and a support spring 307 is fixedly installed between each of the two sliding rods 305 and the limiting seat 304.

[0023] Several single tubes 301 are nested and slidably connected to each other, and the inner diameter of the single tubes 301 increases sequentially, so that the single tubes 301 can be extended or contracted. At the same time, the limiting post 302 is embedded and slidably installed in the limiting groove 303 to ensure that the single tubes 301 do not rotate and are mutually constrained. Several semi-annular rubber strips are fixedly installed side by side on one side of the positioning seat 306, and the semi-annular rubber strips protrude from the positioning seat 306. In use, when the positioning seat 306 is pulled to move the slide rod 305 within the limiting seat 304, the semi-annular rubber strips can be released from the restriction on the single tubes 301, so that external force can be applied to extend or contract the single tubes 301.

[0024] Example 2

[0025] See Figure 2 and Figure 4 A clamping mechanism 4 is provided at one end of the single tube 301. The clamping mechanism 4 includes an extension tube 401, which is slidably installed inside the single tube 301. A limit post 302 is fixedly installed at one end of the extension tube 401, and a shaped tube 402 is fixedly installed at the other end of the extension tube 401. A support seat 403 is sleeved on the outside of the shaped tube 402. A first clamping seat 404 is fixedly installed at one end of the support seat 403. A second clamping seat 405 is rotatably installed on the first clamping seat 404. A rubber pad 406 is fixedly installed on one side of both the first clamping seat 404 and the second clamping seat 405. Two buffer springs 407 are fixedly installed between the second clamping seat 405 and the support seat 403.

[0026] A limiting post 302 is fixedly installed on one side of the extension tube 401, and the limiting post 302 is adapted to the limiting groove 303. Both sides of the shaped tube 402 are provided with strip grooves, and the support seat 403 is adapted to the strip grooves. By providing the strip grooves, the support seat 403 can only move up and down along the shaped tube 402. In use, the support seat 403 is controlled to be located at the bottom of the shaped tube 402, and the first clamp 404 and the second clamp 405 are further controlled to clamp the seedling. During the growth of the seedling, the support seat 403 is moved upward to ensure the vertical growth of the seedling. When the support seat 403 is close to the top of the shaped tube 402, several single tubes 301 are controlled to raise the shaped tube 402 and keep the support seat 403 at the bottom of the shaped tube 402.

[0027] In actual operation, several single tubes 301 with different inner diameters are sequentially installed and the limiting post 302 is slidably installed in the limiting groove 303, so that the single tubes 301 are constrained to each other and can only move up and down. The positioning seat 306 is slidably installed at one end of the single tube 301. Under the action of the support spring 307, the positioning seat 306 clamps the single tube 301 to prevent the single tube 301 from sliding on its own. When in use, the restriction on the single tube 301 can be released by pulling the positioning seat 306, which facilitates the extension or retraction of the single tube 301 and ensures that the device can be adapted to seedlings of different heights for correction treatment.

[0028] By controlling the support base 403 to be located at the bottom end of the irregular tube 402, the first clamp 404 and the second clamp 405 are further controlled to clamp the seedling. When the seedling grows, the support base 403 will be supported to move upward along the irregular tube 402. When the support base 403 is close to the top of the irregular base 402, the single tube 301 further raises the irregular base 402, so that the support base 403 is located at the bottom end of the irregular tube 402, reducing the restriction of the device's own gravity on the growth of the seedling.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
