Description

Technical Field

[0001] The utility model relates to the technical field of breeding equipment, in particular to a seedling raising frame for agricultural planting technology, which is used for cultivating plants, especially for plants that need to adjust the spacing in equal proportion. Background Art

[0002] Seedling racks are often used in agricultural planting. As a multi-layer stacking planting equipment, seedling racks play an important role in the cultivation process of various plants. Its core advantage is that it significantly improves planting efficiency and effectively saves precious land resources by efficiently utilizing three-dimensional space. However, with the continuous advancement of planting technology and the diversification of planting needs, the necessity of adjusting the spacing between seedling racks has become increasingly prominent.

[0003] Different plants have different requirements for environmental conditions such as light, temperature, and humidity during their growth. Therefore, a reasonable interlayer spacing is crucial to ensure the healthy growth of plants. In addition, with the flexible changes in planting plans, such as the promotion of planting patterns such as crop rotation and intercropping, higher requirements are also placed on the adjustment of interlayer spacing in seedling raising racks. However, existing seedling raising racks have obvious deficiencies in adjusting interlayer spacing. For example, the easy-to-adjust seedling raising rack disclosed in CN220140344U uses the traditional layer-by-layer adjustment method, which is not only time-consuming and labor-intensive, but also inefficient, and is easily caused by operational errors. Inaccurate interlayer spacing, which in turn affects the normal growth of plants and the overall planting effect. The limitations of this adjustment method make it difficult for growers to quickly and flexibly adjust the interlayer spacing according to actual needs, limiting the widespread application of seedling raising racks in the field of plant cultivation. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a seedling raising rack for agricultural planting technology, which can realize the simultaneous adjustment of the distance between each layer of trays, thereby greatly simplifying the adjustment process and reducing the operation difficulty and labor intensity.

[0005] The specific scheme of the utility model is as follows:

[0006] A seedling raising rack for agricultural planting technology, comprising:

[0007] A vertically arranged hollow column, the side wall of which is provided with a slot extending axially and penetrating the column body;

[0008] A screw rod is coaxially arranged with the column and can rotate freely, and the outer wall of the screw rod is provided with at least two thread segments from top to bottom, and the pitch of each thread segment increases or decreases;

[0009] A slider is threadedly connected to the screw rod, each thread segment corresponds to a slider, each slider is slidably connected to the column, and all sliders include a protrusion extending into the slot, thereby limiting the slider to only move along the axial direction of the hollow column but not to rotate;

[0010] A tray is coaxially sleeved outside the column, and the tray is fixedly connected to the slider so as to move with the slider;

[0011] A rotating tool used to rotate the screw.

[0012] As a specific implementation of the utility model, the screw is integrally formed, and the screw diameter of each thread segment increases or decreases from top to bottom.

[0013] As a specific implementation of the utility model, the screw rod is fixedly connected by the threaded segments in a detachable manner, such as a square tenon connection, and after the connection, the threaded segments can rotate coaxially and synchronously.

[0014] As a specific implementation of the present invention, for all thread segments, the difference in pitch between adjacent thread segments is the same.

[0015] As a specific implementation of the present invention, for all thread segments, the number of thread turns of each thread segment is equal.

[0016] Compared with the existing technology, it has the following advantages:

[0017] The utility model drives the movement of the slider and then drives the movement of the pallet through unequally spaced threads. Since the threads of each section are unequally spaced, the distance changes of each slider are different when the screw rotates one circle, so the distance between each slider can be adjusted. This adjustment method can synchronously adjust the spacing of multiple sliders, which can not only significantly improve the convenience of adjustment, but also ensure the precise control of the layer spacing.

[0026] The present invention will be further described in detail below in conjunction with the embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0027] Example

[0028] Please refer to Figure 1 to Figure 6 , which shows the structure of a specific embodiment of the seedling raising rack for agricultural planting technology of the utility model. The seedling raising rack for agricultural planting technology of the utility model includes a column 100, a screw 200, a slider 300, a tray 400 and a rotating tool 500, wherein the column 100 is a hollow rotating body structure, which is arranged vertically, and a support plate 110 is fixedly connected to the bottom, so as to be placed on the ground. Of course, in order to make the column 100 more stable, anchor bolts can also be provided to fix the support plate 110 to the ground. The side wall of the column 100 is provided with a slot 120 extending axially and passing through the body of the column 100; the screw 200 is coaxially arranged with the column 100 and can rotate freely. In specific implementation, the bottom of the screw 200 abuts the support plate 200, and the top extends out of the column 100 and is connected to the rotating tool 500. The rotating tool 500 is used to drive the screw 200 to rotate around its center line, from top to bottom, At least two thread segments 210 are provided on the outer wall of the screw 200, and the pitch of each thread segment 210 increases or decreases; the slider 300 is threadedly connected to the screw 200, and each thread segment 210 is correspondingly threadedly connected to a slider 300, each slider 300 is slidably connected to the column 100, and all sliders 300 include a protrusion 310 extending into the slot 120. Due to the limiting effect of the slot 120, when the screw 200 is rotated, each slider 300 can only move along the axial direction of the column 100 but cannot rotate. Since the pitches of the thread segments 210 are not the same, after the screw rotates one circle, the distance between two adjacent sliders 300 changes, thereby adjusting the distance between the two; the tray 400 is coaxially sleeved outside the column 100 and fixedly connected to the slider 300, so that it moves with the slider 300.

[0029] In some embodiments, the screw 200 is integrally formed, and from top to bottom, the diameter of the screw 200 of each threaded segment 210 increases or decreases. At the same time, the diameter of the slider 300 corresponding to each threaded segment 210 also increases or decreases. This makes it easy to install each slider 300 on the threaded segment 210.

[0030] In some embodiments, the screw rod 200 is composed of multiple sections connected in a detachable manner, such as a square tenon connection. Figure 6 As shown, after connection, the thread segments 210 become an integrated structure and can rotate coaxially and synchronously.

[0031] In some embodiments, the difference in pitch of adjacent thread segments 210 from top to bottom is the same, such as Figure 4 As shown, five thread segments are provided, and the pitch ratio of each thread segment from top to bottom is 5:4:3:2:1, and the length ratio of each thread segment is proportional to the pitch ratio of each thread segment, that is, the number of thread turns of each thread segment is the same.

[0032] In some embodiments, the tray 400 is fixed to the slider 300 via bolts in the slots 110 .

[0033] In the present invention, the rotary tool 500 may be a power device or a handle.

[0034] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the embodiments of the present invention should be covered within the protection scope of the present invention.
