Description

Technical Field

[0001] The utility model belongs to the technical field of nursery stock cultivation, and particularly relates to a cultivation device for economic forest nursery stocks. Background Technique

[0002] Nursery stocks are saplings with roots and stems. All saplings cultivated in the nursery, regardless of age, are called nursery stocks before they are out of the nursery. Types of nursery stocks: seedlings, vegetatively propagated seedlings, transplanted seedlings, and seedlings remaining in the bed. When matching nursery stocks, it is necessary to use a support to increase the wind resistance of the nursery stocks.

[0003] Since the growth rate of nursery stocks is relatively fast, especially for relatively small nursery stocks, after being supported by a conventional support, the reserved space is filled as the tree grows, and the frequency of replacing the bundling is relatively high, resulting in a relatively high operation frequency of the conventional nursery stock matching device.

[0004] Therefore, we propose a cultivation device for economic forest nursery stocks to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem of relatively high operation frequency of the conventional nursery stock matching device, and to propose a cultivation device for economic forest nursery stocks.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A cultivation device for economic forest nursery stocks includes a fixed frame, a sliding frame is slidably installed on the fixed frame, a binding strip is slidably sleeved on the sliding frame, one end of the binding strip slides through the sliding frame, a first tension spring is fixedly connected to the rear part of the sliding frame, the outer end of the first tension spring is hooked on the binding strip, a second tension spring is connected between the fixed frame and the sliding frame, a roller is rotatably installed on the binding strip, and the roller is in rolling contact with the sliding frame. Untie the first tension spring and the binding strip, then draw out the binding strip, drive the fixed frame into the ground, tie the binding strip around the tree trunk, then pass the binding strip through the sliding frame, hook the first tension spring on the binding strip, so that the binding strip is tied on the tree trunk, and use the elastic forces of the second tension spring and the first tension spring to act on the tree trunk through the sliding frame and the binding strip to increase the wind resistance of the nursery stock. When the tree trunk becomes thicker, it acts outward on the binding strip, so that the binding strip overcomes the elastic force of the first tension spring to adapt to the thickness of the tree trunk, and improves the matching degree of the device to the growth of the tree trunk.

[0008] Preferably, the fixed frame includes a guide rail and fixed piles, and the fixed piles are symmetrically and fixedly connected to the side ends of the guide rail. Drive the fixed piles into the soil to make the guide rail stable on the upper side, and use the guide rail to guide the sliding of the sliding frame, which is convenient for the binding strip to match the central position of the tree trunk.

[0009] Preferably, the fixing frame further includes reinforcing struts symmetrically and fixedly connected to the sides of the fixing piles. After driving the fixing piles into the ground, embed the lower parts of the reinforcing struts in the ground to increase the support stability of the fixing piles.

[0010] Preferably, the sliding frame includes a frame body and a connecting seat fixedly connected to the back of the frame body. Use the connecting seat to stabilize the rear part of the first tension spring, so that the elastic force of the first tension spring can act on the binding strip to facilitate the binding strip to hold the tree trunk tightly.

[0011] Preferably, the sliding frame further includes leather blocks fixedly embedded in the front of the frame body. Use the leather blocks to contact the target tree trunk to avoid the frame body from wearing the tree trunk and facilitate the protection of seedlings.

[0012] Preferably, the binding strip includes a sleeve fork and a nylon strip, and the nylon strip is fixedly connected to the sleeve fork. Use the elastic force of the first tension spring to act on the nylon strip to make the nylon strip hold tightly on the tree trunk.

[0013] Preferably, the roller includes a retaining disc and a rolling rod, and the retaining discs are fixedly connected to both ends of the rolling rod. Use the rolling rod to roll along the frame body to reduce the moving resistance of the sleeve fork.

[0014] In summary, the technical effects and advantages of the present utility model are as follows:

[0015] 1. Untie the first tension spring and the binding strip, then draw out the binding strip, drive the fixing frame into the ground, tie the binding strip around the tree trunk, then pass the binding strip through the sliding frame, hook the first tension spring on the binding strip, so that the binding strip is tied to the tree trunk. Use the elastic forces of the second tension spring and the first tension spring to act on the tree trunk through the sliding frame and the binding strip to increase the wind resistance of the seedlings. When the tree trunk grows thicker, it acts outward on the binding strip, so that the binding strip overcomes the elastic force of the first tension spring to adapt to the thickness of the tree trunk and improve the matching degree of the device to the growth of the tree trunk.

[0016] 2. Drive the fixing piles into the ground to keep the guide rails stable on the upper side, and use the guide rails to guide the sliding of the sliding frame to facilitate the binding strip to match the central position of the tree trunk. BRIEF DESCRIPTION OF THE DRAWINGS

The fixed piles 22 are nailed into the soil to make the guide rail 21 stable on the upper side, and the guide rail 21 is used to guide the sliding of the slide frame 3.

[0026] Refer to Figure 1 and 2 , the fixed frame 2 further includes a reinforcement strut 23, and the reinforcement strut 23 is symmetrically fixedly connected to the side part of the fixed pile 22. After the fixed pile 22 is nailed into the soil, the lower part of the reinforcement strut 23 is embedded in the ground to increase the support stability of the fixed pile 22.

[0027] Refer to Figure 1 , 2 and 3, the slide frame 3 includes a frame body 31 and a connecting seat 32, the frame body 31 is slidably installed on the guide rail 21, the end of the first tension spring 6 facing away from the restraint strip 4 is fixedly connected to the connecting seat 32, and the connecting seat 32 is fixedly connected to the back of the frame body 31. The connecting seat 32 is used to stabilize the rear part of the first tension spring 6, so that the elastic force of the first tension spring 6 can act on the restraint strip 4.

[0028] Refer to Figure 1 and 3, the carriage 3 further includes a leather block 33, and the leather block 33 is fixedly embedded in the front part of the frame body 31. The leather block 33 is used to contact the target tree trunk to prevent the frame body 31 from wearing the tree trunk.

[0029] Referring to Figure 1 , 3 and 4, the binding strip 4 includes a sleeve fork 41 and a nylon strip 42. The front part of the first tension spring 6 is hooked to the rear part of the nylon strip 42. The sleeve fork 41 is slidably sleeved on the frame body 31, and the nylon strip 42 slidably penetrates through the frame body 31. The nylon strip 42 is fixedly connected to the sleeve fork 41.
