Description

Technical Field

[0001] This utility model is an agronomic cultivation rack, belonging to the field of agriculture. Background Technology

[0002] Agronomic cultivation racks are structured support systems used in agricultural planting and horticultural cultivation, designed to provide support for plants and improve space utilization. Multiple support sections, equidistant from top to bottom, are installed between two vertically arranged aluminum profile guide rails to support the cultivation boxes. Multiple protrusions are then machined on the lower connecting strip at the bottom of the support sections, allowing two sides of one end of the cultivation box to pass through the gaps between corresponding protrusions. The bottom of the cultivation box then contacts the upper surface of the support section, at which point the protrusions are engaged with the upper edge of the inner wall of the cultivation box, leaving one end of the cultivation box suspended. This effectively restricts the position of the cultivation box. However, in this type of agronomic cultivation rack, because the cultivation box needs to be filled with soil or other culture media, the weight of the soil or other culture media acts on the protrusions, causing them to bear a significant load. Therefore, the protrusions are more likely to be damaged due to stress deformation, affecting the overall structural stability. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an agronomic cultivation rack to solve the problems mentioned in the background art. This utility model realizes the transfer of the load on the protrusion, prevents the protrusion from deforming and being damaged, improves the stability of the structure, and reduces the strength requirements of the protrusion.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an agronomic cultivation rack includes a base frame. Two aluminum profile guide rails are installed at both ends of the base frame. Two rows of support parts for supporting the cultivation boxes are arranged from top to bottom on the top of the base frame. The cross-section of each support part is "V"-shaped, and the upper surface of each support part is horizontally arranged. An upper connecting strip is fixedly connected to one end of each support part. The end of the upper connecting strip is connected to the corresponding aluminum profile guide rail by bolts. A lower connecting strip is fixedly connected to the end of each support part away from the upper connecting strip. The lower connecting strip has multiple protrusions equidistantly installed on the side opposite to the supporting part for locking onto the upper edge of the inner wall of the culture box. A transverse screw is provided on one side of the supporting part, and the two ends of the transverse screw are connected to corresponding aluminum profile guide rails through adjusting parts. Multiple sliders are sleeved on the transverse screw, and a transverse hole is opened on one side of the slider. The transverse screw passes through the transverse hole, and a limiting nut is provided on both sides of the transverse hole along the length direction of the transverse screw. The limiting nut is threadedly connected to the transverse screw. A pressing part for abutting against the protrusions is connected and fixed at the lower end of the slider.

[0005] Furthermore, the adjusting component includes a connecting block, and detachable connecting blocks are installed at both ends of the transverse screw. A vertical hole is opened on the upper surface of the connecting block, and a vertical screw is inserted into the vertical hole. The end of the vertical screw is connected to the aluminum profile guide rail through a connecting component. Adjusting nuts are provided on both sides of the vertical hole along the length direction of the vertical screw, and the adjusting nuts are threadedly connected to the vertical screw.

[0006] Furthermore, the connecting block has a first through hole on the side facing the transverse screw, the end of the transverse screw passes through the first through hole, and a first nut is provided on both sides of the first through hole along the length direction of the transverse screw, and the first nut is threadedly connected to the transverse screw.

[0007] Furthermore, the connector includes lugs, and lugs are installed at both ends of the aluminum profile guide rail. A second through hole is provided on the upper surface of the lug, and the end of the vertical screw passes through the second through hole. A second nut is provided on both sides of the second through hole along the length direction of the vertical screw, and the second nut is threadedly connected to the vertical screw.

[0008] Furthermore, the upper connecting strip and the lifting part are integrally formed, the lower connecting strip and the lifting part are integrally formed, and the protrusion and the lower connecting strip are integrally formed.

[0009] Furthermore, a collection box is installed on the upper surface of the bottom frame, and both ends of the collection box are recessed inward to form recesses. The lower end of the aluminum profile guide rail is inserted into the recesses, and universal brake wheels are installed at the four corners of the lower surface of the bottom frame.

[0010] The beneficial effects of this utility model are:

[0011] 1. Adjust the position of the slider along the transverse screw according to the spacing between the protrusions, so that the pressing part on the slider abuts against the protrusion. Then, use two limit nuts to limit the relative position of the slider and the transverse screw. Since the two ends of the transverse screw are connected to the corresponding aluminum profile guide rails, when the soil or other culture medium in the culture box acts on the protrusion, the load will be transferred to the aluminum profile guide rail through the pressing part, slider and transverse screw, thus transferring the load on the protrusion, preventing deformation and damage to the protrusion, improving the stability of the structure and reducing the strength requirements of the protrusion.

[0012] 2. Adjust the height of the connecting block along the vertical screw, thereby changing the spacing between two adjacent horizontal screws. This ensures that the spacing of the horizontal screws meets the requirements of the support section spacing. By using the adjusting nut to limit the position of the connecting block and the vertical screw, the position of the horizontal screw is restricted. At the same time, the horizontal screw, the pressing part, etc. work together to prevent the support section from sliding down after being pressed by the culture box, thus reducing the load on the bolts that restrict the relative position of the support section and the aluminum profile guide rail.

[0013] 3. Two first nuts are used to restrict the relative position of the horizontal screw and the connecting block, which facilitates the assembly and disassembly of the horizontal screw and the connecting block, and also facilitates the addition or reduction of the number of sliders on the horizontal screw as needed. Two second nuts are used to restrict the relative position of the vertical screw and the lug, which facilitates the assembly and disassembly of the vertical screw and the aluminum profile guide rail, and also facilitates the addition of the number of connecting blocks on the vertical screw as needed.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1This utility model provides a technical solution: an agronomic cultivation rack, including a base frame 1, with two aluminum profile guide rails 2 fitted together at both ends of the base frame 1, a collection box 4 installed on the upper surface of the base frame 1, with both ends of the collection box 4 recessed inward to form recesses 10, the lower ends of the aluminum profile guide rails 2 inserted into the recesses 10, the design of the recesses 10 does not affect the connection between the aluminum profile guide rails 2 and the base frame 1, and universal brake wheels 3 are installed at the four corners of the lower surface of the base frame 1, so that the culture medium falling from the cultivation box 9 will fall into the collection box 4, realizing the centralized collection of the spilled culture medium.

[0023] See Figures 1-3 Above the base frame 1, there are two rows of support sections 7 arranged from top to bottom to support the culture box 9. The cross-section of the support section 7 is "V" shaped, and the upper surface of the support section 7 is horizontal. One end of the support section 7 is connected and fixed to an upper connecting strip 13, which is integrally formed with the support section 7. The end of the upper connecting strip 13 is connected to the corresponding aluminum profile guide rail 2 by bolts. The end of the support section 7 away from the upper connecting strip 13 is connected and fixed to a lower connecting strip 19, which is integral with the support section 7. The lower connecting strip 19 has multiple protrusions 20 at equal intervals on the side opposite to the support part 7, which are used to lock onto the upper edge of the inner wall of the culture box 9. The protrusions 20 and the lower connecting strip 19 are integrally formed, so that the two sides of one end of the culture box 9 pass through the gap between the corresponding two protrusions 20, and then the bottom of the culture box 9 contacts the upper surface of the support part 7. At this time, the protrusions 20 are locked onto the upper edge of the inner wall of the culture box 9, and one end of the culture box 9 is in a suspended state, thus restricting the position of the culture box 9.

[0024] See Figure 1 , Figure 2 and Figure 5 A horizontal screw 17 is provided on one side of the support part 7, parallel to the support part 7. Both ends of the horizontal screw 17 are equipped with detachable connecting blocks 5. A vertical hole 24 is opened on the upper surface of the connecting block 5. A vertical screw 6 is inserted into the vertical hole 24. Adjusting nuts 15 are provided on both sides of the vertical hole 24 along the length of the vertical screw 6. The adjusting nuts 15 are threadedly connected to the vertical screw 6. The height of the connecting block 5 is adjusted along the vertical screw 6, thereby changing the spacing between two adjacent horizontal screws 17. This allows the spacing of the horizontal screws 17 to meet the spacing requirements of the support part 7. By using the adjusting nuts 15 to restrict the position of the connecting block 5 and the vertical screw 6, the position of the horizontal screw 17 is restricted. At the same time, the horizontal screw 17 and the pressing part work together to prevent the support part 7 from sliding down after being pressed by the culture box 9, thus reducing the load on the bolts that restrict the relative position of the support part 7 and the aluminum profile guide rail 2.

[0025] See Figure 1 , Figure 2 and Figure 5The connecting block 5 has a first through hole 23 on the side facing the transverse screw 17. The end of the transverse screw 17 passes through the first through hole 23. A first nut 16 is provided on both sides of the first through hole 23 along the length of the transverse screw 17. The first nut 16 is threadedly connected to the transverse screw 17. Both ends of the aluminum profile guide rail 2 are equipped with lugs 11. A second through hole 12 is provided on the upper surface of the lug 11. The end of the vertical screw 6 passes through the second through hole 12. The second through hole 12 is provided on both sides of the vertical screw 6 along the length of the vertical screw 6. A second nut 14 is provided, which is threadedly connected to the vertical screw 6. Two first nuts 16 are used to restrict the relative position of the horizontal screw 17 and the connecting block 5, which facilitates the assembly and disassembly of the horizontal screw 17 and the connecting block 5, and also facilitates the addition or reduction of the number of sliders 8 on the horizontal screw 17 as needed. Two second nuts 14 are used to restrict the relative position of the vertical screw 6 and the lug 11, which facilitates the assembly and disassembly of the vertical screw 6 and the aluminum profile guide rail 2, and also facilitates the addition of the number of connecting blocks 5 on the vertical screw 6 as needed.

[0026] See Figures 1-5 Multiple sliders 8 are fitted onto the transverse screw 17. A transverse hole 22 is formed on one side of each slider 8, through which the transverse screw 17 passes. Limiting nuts 18 are provided on both sides of the transverse hole 22 along the length of the transverse screw 17. The limiting nuts 18 are threadedly connected to the transverse screw 17. A pressing part 21 for abutting against the protrusion 20 is fixed to the lower end of each slider 8. The position of the slider 8 is adjusted along the transverse screw 17 according to the spacing between the protrusions 20, so that the pressing part 21 on the slider 8 abuts against the protrusion 20. Then, two limiting nuts 18 are used to limit the relative position of the slider 8 and the transverse screw 17. Since the two ends of the transverse screw 17 are connected to the corresponding aluminum profile guide rail 2, when the soil or other culture medium in the culture box 9 acts on the protrusion 20, the load will be transferred to the aluminum profile guide rail 2 through the holding part 21, the slider 8 and the transverse screw 17, so as to prevent the protrusion 20 from deforming and being damaged, improve the stability of the structure and reduce the strength requirements of the protrusion 20.
