Description

Technical Field

[0001] The utility model relates to the technical field of soilless cultivation of vegetables, in particular to a three-dimensional support frame for soilless cultivation of vegetables. Background Technique

[0002] Soilless cultivation of vegetables is a modern planting technique. It uses media such as water, peat, vermiculite, etc. as the substrate for the plant roots, enabling the plant roots to directly contact the nutrient solution for growth. This cultivation method is not restricted by soil conditions and can be carried out in places without soil, such as deserts, beaches, deserted islands, etc., as long as there is an appropriate supply of fresh water. The soilless cultivation technique enables vegetable planting to be no longer restricted by seasons and can be carried out throughout the year. Moreover, by monitoring and adjusting the components in the nutrient solution, the growth requirements of the crops can be met, and the growth process of the plants can be precisely controlled. During cultivation, in order to increase the cultivation quantity, generally, multiple three-dimensional support frames are arranged at intervals in the greenhouse. Multiple layers of vegetables are cultivated on each three-dimensional support frame, and multiple vegetable cultivation frames are sequentially placed on each layer. However, before and after cultivation, it is necessary to sequentially place multiple vegetable cultivation frames on the support frame and unload them after growth, mostly by manual handling and moving them out between two rows of support frames, or pushing a cart between two rows of support frames and sequentially transporting them back and forth between the support frame and the cart. Therefore, there needs to be a sufficient safe distance for installation, disassembly, and handling between two support frames. For this reason, a three-dimensional support frame for soilless cultivation of vegetables is designed, which is provided with a horizontal conveying structure between the two ends, with the two ends serving as the feeding end and the discharging end respectively, facilitating the conveyance of the vegetable cultivation frames from one end to the other end and facilitating disassembly from the other side. Thus, the distance between two adjacent rows of support frames can be reduced, and at the same time, it is convenient to centrally load and unload at the two ends respectively, ensuring the smoothness of loading and unloading.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figures 1-5 A three-dimensional support frame for soilless cultivation of vegetables includes a support frame 1 and a plurality of vegetable culture frames 3. Multiple layers of nutrient solution tanks 2 are sequentially arranged on the support frame 1 from top to bottom. Side slide rails 5 are arranged on both sides above each layer of nutrient solution tank 2. The vegetable culture frame 3 can be placed between the two side slide rails 5 so that the bottom of the vegetable culture frame 3 can extend into the nutrient solution tank 2, and a gap for vegetable root extension is arranged between the vegetable culture frame 3 and the inner bottom of the nutrient solution tank 2. Horizontal conveying structures are arranged on the two side slide rails 5, and also include a horizontal driving structure for synchronously driving the two horizontal conveying structures to move synchronously.

[0024] Specifically, the horizontal conveying structure includes a conveyor belt 6 which is embedded and rotatably connected to the side slide rail 5, and a plurality of tooth blocks 7 are evenly installed on the conveyor belt 6. The tooth block 7 arranged on the top of the conveyor belt 6 protrudes from the top end surface of the side slide rail 5. Both sides of the vegetable cultivation frame 3 are installed with slide bars 8 which slide with the side slide rail 5. The bottom of the slide bar 8 is provided with a plurality of tooth grooves 9 which are adapted to the adjacent plurality of tooth blocks 7. When the vegetable cultivation frame 3 is placed between the two side slide rails 5, the plurality of tooth grooves 9 can be engaged with the plurality of tooth blocks 7. By rotating the conveyor belt 6, the vegetable cultivation frame 3 can be transported to the other end.

[0025] Specifically, the horizontal driving structure includes a driving motor 11 fixedly installed at the bottom of the nutrient solution tank 2 and a transmission shaft 12 rotatably connected to the bottom of the nutrient solution tank 2. The conveyor belt 6 is rotatably connected to the side slide rail 5 through the two transmission shafts 12. The driving motor 11 and the transmission shaft 12 are connected through a transmission component 13, wherein the two transmission shafts 12 at one end are connected to the transmission shaft 12 through a transmission component 2 14. The driving motor 11 is started, and the transmission shaft 12 is driven to rotate through the transmission cooperation of the transmission component 1 13. The two transmission components 2 14 are used to drive the two transmission shafts 12 at one end to rotate, thereby driving the conveyor belts 6 on both sides to rotate synchronously. Furthermore, the transmission component 1 13 and the transmission component 2 14 can both be set to a transmission form of a sprocket chain or a transmission wheel and transmission belt.

[0026] Specifically, the bottom of the vegetable cultivation frame 3 is set as a filter structure 4. By setting the bottom of the vegetable cultivation frame 3 as the filter structure 4, it is convenient for the nutrient solution in the nutrient solution tank 2 to enter the inside of the vegetable cultivation frame 3, and at the same time, it is convenient for the vegetable roots to extend out of the vegetable cultivation frame 3 into the nutrient solution tank 2. Further, the filter structure 4 can be set as a flat plate structure with a plurality of circular or square pores.

[0027] Specifically, the conveyor belt 6 is arranged on the side of the side slide rail 5 away from the nutrient solution tank 2. By arranging the conveyor belt 6 on the side away from the nutrient solution tank 2, it is avoided that the nutrient solution splashes onto the conveyor belt 6 when adding the nutrient solution into the nutrient solution tank 2, ensuring the transmission stability of the conveyor belt 6.

[0028] Specifically, a support frame 10 for supporting the conveyor belt 6 is fixedly installed on the side slide rail 5. Through the arrangement of the support frame 10, it is convenient to support the conveyor belt 6, so that the tooth blocks 7 on the conveyor belt 6 can always be tightly attached to the tooth grooves 9, ensuring the stability of the engagement.
