Multi-layer vertical planting racks inside the planting greenhouse

Abstract

This utility model discloses a multi-layer three-dimensional planting rack for greenhouses, including a greenhouse beam, a left hanging panel, and a right hanging panel. The left hanging panel is fitted to the left side wall of the greenhouse beam, and the right hanging panel is fitted to the right side wall. U-shaped mounting parts are welded to the facing surfaces of both the left and right hanging panels. In this utility model, the planting troughs and L-shaped hanging parts are quickly assembled and disassembled through the insertion and connection of positioning posts and positioning slots, and the threaded connection of threaded posts and nuts. Compared with the fixed connection structure of traditional three-dimensional planting racks, the loading and unloading time of a single planting trough is significantly shortened, greatly reducing manpower input. Simultaneously, the detachable design allows the planting rack to be disassembled and stored when not in use, reducing storage space requirements and significantly improving the flexibility of operations within the greenhouse. The staggered arrangement of the planting troughs with the left and right hanging panels effectively solves the problem of inter-layer shading caused by traditional multi-layer stacking arrangements.

Description

Technical Field

[0001] This utility model relates to the field of planting rack technology, and in particular to a multi-layer three-dimensional planting rack for planting greenhouses. Background Technology

[0002] In the field of agricultural planting, greenhouses provide a controllable environment for crop growth, effectively improving crop yield and quality. Traditional greenhouses mostly use flat planting racks. With the development of agricultural technology, the drawbacks of this type of planting rack have gradually become apparent. In order to improve the utilization rate of greenhouse space, three-dimensional planting racks have emerged.

[0003] However, existing multi-layer planting racks have the following drawbacks: The fixed connections between layers make loading and unloading cumbersome, requiring significant manpower and time. Furthermore, their large size during transport and storage space demands severely impact greenhouse operational efficiency and space utilization flexibility. Additionally, the stacking arrangement of multi-layer planting racks often leads to severe shading between layers, resulting in insufficient sunlight for lower-layer crops, inhibiting photosynthesis and affecting crop growth and yield.

[0004] To address this issue, a multi-layered, three-dimensional planting rack for greenhouses was proposed. This rack offers advantages such as convenient loading and unloading, and effectively reduces shading between layers to improve light transmission, thereby resolving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-layered three-dimensional planting rack for planting greenhouses.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a multi-layer three-dimensional planting rack inside a planting greenhouse, including a greenhouse beam, a left hanging panel, and a right hanging panel. The left hanging panel is fitted to the left side wall of the greenhouse beam, and the right hanging panel is fitted to the right side wall of the greenhouse beam. U-shaped mounting parts are welded to the facing surfaces of the left and right hanging panels, and the two sides of the U-shaped mounting parts are fixedly connected to the greenhouse beam by bolts. Several L-shaped hanging parts are welded at equal intervals to the separating surfaces of the left and right hanging panels, and a planting trough can be detachably installed on each L-shaped hanging part. A positioning groove is opened on the top of each L-shaped hanging part. An installation block is fixed to the end of the planting trough connected to the L-shaped hanging part, and a positioning post that inserts into the positioning groove is integrally formed on the installation block. A threaded post is fixed to the edge of the bottom surface of the planting trough, and the bottom end of the threaded post passes through the L-shaped hanging part and is threadedly connected to a nut.

[0007] As a further description of the above technical solution: the planting troughs of the left and right hanging panels are staggered, and the openings of the planting troughs are facing upwards.

[0008] As a further description of the above technical solution: the planting trough is generally square bucket-shaped, and the bottom surface of the planting trough is provided with drainage holes, and the inside of the planting trough is filled with planting substrate.

[0009] As a further description of the above technical solution: the bottom surface of the mounting block is provided with multiple positioning posts, and the top of the L-shaped suspension component is provided with several positioning grooves corresponding to the positioning posts.

[0010] As a further description of the above technical solution: the bottom of the L-shaped suspension member has an insertion hole corresponding to the threaded post, and the L-shaped suspension member fits into the side and bottom surface of the planting trough.

[0011] As a further description of the above technical solution: the bottom surface of the L-shaped suspension component is fixed with several triangular reinforcing blocks, and the several triangular reinforcing blocks are welded to the left suspension panel or the right suspension panel.

[0012] This utility model has the following beneficial effects: In this invention, the planting trough and L-shaped suspension component are quickly assembled and disassembled through the insertion and connection of the positioning column and positioning groove, and the threaded connection of the threaded column and nut. Compared with the fixed connection structure of traditional three-dimensional planting racks, the loading and unloading time of a single planting trough is significantly shortened, greatly reducing manpower input. At the same time, the detachable design allows the planting rack to be disassembled and stored when not in use, reducing storage space requirements and significantly improving the flexibility of operations in the greenhouse. The staggered arrangement of the planting troughs with left and right hanging panels effectively solves the problem of interlayer obstruction caused by traditional multi-layer stacking. The U-shaped mounting component is reinforced by double bolts to fix and strengthen the connection between the panel and the upright beam, and the triangular reinforcing block at the bottom of the L-shaped suspension component forms a triangular support structure, giving a single suspension component a strong load-bearing capacity to meet the needs of high-density planting. Moreover, the overall structure's wind load resistance is improved, and it can remain stable even in greenhouse ventilation or slight vibration environments, avoiding the risk of crop lodging.

[0015] 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.

[0016] According to an embodiment of this utility model, a multi-layer three-dimensional planting rack for planting greenhouses is provided.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, the multi-layer three-dimensional planting rack in the greenhouse according to this embodiment of the utility model includes a greenhouse beam 1, a left hanging panel 2, and a right hanging panel 3. The left hanging panel 2 is attached to the left side wall of the greenhouse beam 1, and the right hanging panel 3 is attached to the right side wall of the greenhouse beam 1. U-shaped mounting parts 4 are welded to the facing surfaces of the left hanging panel 2 and the right hanging panel 3, and the two sides of the U-shaped mounting parts 4 are fixedly connected to the greenhouse beam 1 by bolts. Several L-shaped hanging parts 5 are welded at equal intervals to the separating surfaces of the left hanging panel 2 and the right hanging panel 3, and a planting trough 6 can be detachably installed on each L-shaped hanging part 5. The top of each of the five planting troughs is provided with a positioning groove 11. A mounting block 7 is fixed to one end of the planting trough 6 connected to the L-shaped suspension component 5. A positioning post 10, which interlocks with the positioning groove 11, is integrally formed on the mounting block 7. A threaded post 8 is fixed to the edge of the bottom surface of the planting trough 6, and the bottom end of the threaded post 8 passes through the L-shaped suspension component 5 and is threadedly connected to a nut 9. The greenhouse beam 1, serving as the load-bearing foundation of the entire planting frame, is made of high-strength steel and can stably support the weight of the multi-layered planting structure. The left suspension panel 2 is tightly fitted to the left side wall of the greenhouse beam 1, and the right suspension panel 3 is correspondingly fitted to the right side wall. Both are initially fixed to the beam through precision welding. To further enhance connection stability, U-shaped mounting components 4 are welded to the facing surfaces of the left and right suspension panels 2 and 3. These mounting components are made of 5mm thick steel plate bent into shape, and their two side panels are fixed to the side walls of the greenhouse beam 1 using M10 high-strength bolts with a bolt spacing of 15cm to ensure that the panels do not wobble when supporting the planting trough 6. The left and right hanging panels 2 and 3 have several L-shaped hanging parts 5 welded at equidistant intervals of 30cm on their separated surfaces. Each L-shaped hanging part 5 can be independently disassembled and installed with a planting trough 6. To achieve precise positioning, each L-shaped hanging part 5 has a positioning groove 11 with a depth of 2cm at its top. A rectangular mounting block 7 is fixed to the end of the planting trough 6 that connects to the L-shaped hanging part 5. The bottom surface of the mounting block 7 is integrally formed with a positioning post 10 that matches the positioning groove 11. The gap between the two when they are inserted is controlled within 0.5mm to effectively prevent the planting trough 6 from shifting laterally. In addition, a threaded post 8 with a diameter of 8mm is fixed to the front and rear edges of the bottom surface of the planting trough 6. The bottom end of the threaded post 8 vertically penetrates the L-shaped hanging part 5 and is locked in place by a nut 9 (a butterfly nut that is easy to disassemble and install). This double fixing structure ensures that the planting trough 6 remains stable when the greenhouse is ventilated or under slight vibration. Please refer to Figure 3The planting troughs 6 on the left hanging panel 2 and the right hanging panel 3 are staggered, with their openings facing upwards. The planting troughs 6 on the left and right hanging panels 2 are horizontally offset by 20cm from each other. This layout effectively prevents mutual shading between the upper and lower planting troughs 6, allowing the lower crops to receive more diffused light. Simultaneously, all the openings of the planting troughs 6 face upwards, with rounded edges to facilitate planting and prevent substrate spillage. The opening width is uniformly designed at 40cm, meeting the growth space requirements of most leafy vegetables.

[0018] Please refer to Figure 1 , Figure 2 and Figure 4 The planting trough 6 has a square bucket-shaped structure, with drainage holes 12 on its bottom surface. The trough is filled with a planting substrate (not shown in the diagram). The planting trough 6 is injection molded from food-grade PP material, and is 80cm long, 40cm wide, and 25cm deep. The bottom of the trough slopes inward at a 5° angle to facilitate rapid drainage of excess water. Drainage holes 12, each 1cm in diameter, are evenly distributed on the bottom surface of the planting trough 6, spaced 5cm x 5cm apart, ensuring smooth drainage while preventing substrate loss. The trough is filled with a planting substrate (not shown in the diagram) composed of peat moss, perlite, and coconut coir in a 3:1:1 ratio. This substrate has good water retention and aeration properties, meeting the needs of crop root growth.

[0019] Please refer to Figure 2 and Figure 4 The bottom surface of the mounting block 7 is provided with multiple positioning posts 10. The top of the L-shaped suspension component 5 is provided with several positioning grooves 11 corresponding to the positioning posts 10. The mounting block 7 is made of ABS engineering plastic and is fixed to the planting trough 6 by hot melt welding. Three positioning posts 10 with a diameter of 1.5cm are evenly provided on its bottom surface. The top of the positioning posts is designed with rounded corners to facilitate insertion into the positioning grooves 11. The top of the L-shaped suspension component 5 is provided with three matching positioning grooves 11 corresponding to the positions of the positioning posts 10. The inner wall of the positioning grooves 11 is roughened to increase the friction with the positioning posts 10 and further improve the connection stability.

[0020] Please refer to Figure 2 and Figure 4The bottom of the L-shaped suspension component 5 has an insertion hole 13 corresponding to the threaded post 8, and the L-shaped suspension component 5 fits against the side and bottom of the planting trough 6. The L-shaped suspension component 5 is made of 3mm thick steel plate and is stamped. Its horizontal section is 25cm long and its vertical section is 10cm high. The bottom of the L-shaped suspension component 5 has an insertion hole 13 with a diameter of 9mm corresponding to the threaded post 8. The edge of the insertion hole 13 is chamfered to avoid wear when the threaded post 8 is inserted. In the assembled state, the vertical section of the L-shaped suspension component 5 fits completely against the side of the planting trough 6, and the horizontal section is in close contact with the bottom of the planting trough 6, distributing the weight load of the planting trough 6 through surface contact.

[0021] Please refer to Figure 2 and Figure 4 The bottom surface of the L-shaped suspension component 5 is fixed with several triangular reinforcing blocks 14, and these triangular reinforcing blocks 14 are welded to the left suspension panel 2 or the right suspension panel 3. In order to improve the load-bearing capacity of the L-shaped suspension component 5, three triangular reinforcing blocks 14 are fixed at the angle between its bottom surface and the vertical section. The reinforcing blocks are cut from 2mm thick steel plates, each with a side length of 5cm. They are welded to the bottom surface of the L-shaped suspension component 5 and the left suspension panel 2 (or the right suspension panel 3) respectively through a full welding process to form a stable triangular support structure, thereby increasing the load-bearing capacity of a single L-shaped suspension component 5 to 50kg, which can meet the needs of high-density planting.

[0022] Working principle: In operation, the greenhouse beam 1 serves as the load-bearing foundation. The left and right hanging panels 2 and 3 are fixed to the side walls using U-shaped mounting brackets 4, forming a symmetrical hanging frame. L-shaped hanging brackets 5 are welded equidistantly to the panel surface. They precisely align with the positioning posts 10 of the planting trough 6 mounting block 7 via positioning grooves 11, and are then secured with nuts 9 after passing through the insertion holes 13 with threaded posts 8, achieving double fixation of the planting trough 6 and ensuring assembly accuracy and structural stability. The staggered arrangement of the planting troughs 6 allows sunlight to reach the lower crops layer by layer, promoting photosynthesis by improving light utilization. Triangular reinforcing blocks 14 distribute the weight of the planting troughs 6, ensuring the multi-layered structure remains stable when fully loaded with crops, achieving efficient use of three-dimensional space. Depending on the crop growth cycle, the planting troughs 6 can be easily disassembled for crop rotation or pest and disease control. During the off-season, the components can be disassembled and stored separately, reducing space occupation. By flexibly adjusting the number and density of the planting troughs 6, the growth characteristics of different crops can be adapted, achieving intensive and refined management of greenhouse cultivation.
