Description

Technical Field

[0001] This utility model relates to the field of agricultural planting, and in particular to a soilless cultivation device for agricultural planting. Background Technology

[0002] An existing patent (publication number: CN109392691A) discloses a soilless cultivation device, including an upper nutrient solution tank, a lower nutrient solution tank, a support frame, a planting board, and a transplanter. The support frame is rectangular and includes an upper support frame, a middle support frame, and a lower support frame arranged vertically from top to bottom. The lower nutrient solution tank is located inside the lower support frame. The upper nutrient solution tank is located inside the upper support frame. The planting board is fixed to the frame of the vertical surface of the middle support frame. The top of the lower nutrient solution tank is open. The vertical surface of the planting board has a matrix of holes, and the transplanter penetrates the planting board through the holes. The upper nutrient solution tank is connected to a nutrient solution supply pipe. The nutrient solution supply pipe has openings at each transplanter to supply nutrient solution. The lower nutrient solution tank is connected to a nutrient solution pump, and the outlet of the nutrient solution pump is connected to the upper nutrient solution tank. However, in this device, the roots of the seedlings in the transplanter are all placed together in the planting board without a filtration structure, resulting in poor performance. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a soilless cultivation device for agricultural planting. This device ensures the relative cleanliness of the culture solution used for each seedling, intercepts impurities such as residual roots, fallen leaves, and mud in the water, and allows the culture solution to be more evenly distributed around the roots. Simultaneously, it does not impede air circulation and promotes respiration. The strip-shaped culture trough is designed with two chambers, upper and lower, where the lower water outlet chamber allows for the sedimentation of impurities and some pathogens.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A soilless cultivation device for agricultural planting includes a strip-shaped cultivation trough, side connecting ears, a rotating cover plate, a rotating shaft, trapezoidal partitions, strip-shaped blocking plates, side sliding rods, and anti-detachment strip rods. The strip-shaped cultivation trough has an upper opening at its upper part and a lower water outlet cavity at its lower part. The lower water outlet cavity has a lower water outlet connector on its side, which is connected to a water pipe. The strip-shaped cultivation trough also has an upper water inlet connector on its side, which is connected to a water pipe. The upper opening of the cultivation trough has multiple inner limiting protrusions with semi-circular limiting grooves. The upper part of the strip-shaped cultivation trough has a positioning slot, and the bottom of the strip-shaped cultivation trough has multiple drainage holes. The trapezoidal partitions are adapted to the strip-shaped cultivation trough and are inserted into it. The trapezoidal partitions are also adapted to the positioning slots and are inserted into them. The multiple trapezoidal partitions are evenly distributed inside the strip-shaped cultivation trough and have multiple filter holes.

[0006] The rotating cover has a cover side sleeve on its side, and the side of the strip culture tank is connected to the side connecting ear. The cover side sleeve fits into the side connecting ear, and the side connecting ears are symmetrically arranged on both sides of the cover side sleeve. The cover side sleeve is connected to the symmetrical side connecting ears through a rotating shaft. The rotating cover has multiple U-shaped slots, and the diameter of the U-shaped slots is the same as that of the semi-circular limiting slot. Beneficial effects

[0007] 1. The strip-shaped cultivation trough of this utility model is divided into upper and lower areas. The upper area is the hydroponic area, and the lower water outlet area is the water outlet area. During use, the culture solution enters the strip-shaped cultivation trough through the upper water inlet connector. Seedlings are placed inside the trough with their roots positioned at the top. An inner limiting protrusion limits the seedlings on one side, ensuring even distribution within the trough. A trapezoidal partition passes through a positioning slot and is inserted into the trough, dividing the hydroponic area into multiple sections. Small, equal-sized areas are used to cultivate one seedling per area. A trapezoidal partition acts as a filter, preventing the roots of the seedlings from contaminating each cultivation area in soilless cultivation. The cover plate is connected to side connecting ears via a rotating shaft. The cover plate is mounted above the strip cultivation trough and is designed to be rotatable for easy opening and removal of the seedlings. When the cover plate is closed, a U-shaped slot and a semi-circular limiting slot form a circular hole to secure the seedlings and prevent them from tilting in soilless cultivation.

[0008] 2. In this utility model, the strip-shaped blocking plate is inserted into the lower water outlet cavity. Under normal conditions, the strip-shaped blocking plate seals the drain hole, preventing the culture medium from falling into the lower water outlet cavity in hydroponics. The side sliding rod passes through the lower water outlet cavity and connects to the anti-detachment rod. The sliding distance of the side sliding rod within the strip-shaped blocking plate is the sliding displacement of the strip-shaped blocking plate, preventing the strip-shaped blocking plate from sliding out in hydroponics. The anti-detachment rod can be pulled to control the movement of the strip-shaped blocking plate, thereby controlling the alignment and misalignment of the docking hole and the drain hole. When needed... When draining the culture solution, pull the strip-shaped stopper to align the connecting hole with the drain hole, allowing the culture solution in the strip culture tank to enter the lower outlet chamber and exit from the lower outlet connector. This device ensures the relative cleanliness of the culture solution for each seedling, intercepting impurities such as residual roots, fallen leaves, and mud in the water, making the culture solution more evenly distributed around the roots, while not affecting air circulation and promoting respiration. The strip culture tank is designed with two chambers, and the lower outlet chamber can settle impurities and some pathogens during use. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0017] Example 1:

[0018] A soilless cultivation device for agricultural planting includes a strip-shaped cultivation trough 01, side connecting ears 02, a rotating cover plate 09, a rotating shaft 11, a trapezoidal partition 15, a strip-shaped blocking plate 17, a side sliding rod 19, and an anti-detachment strip rod 20. The strip-shaped cultivation trough 01 has an upper opening 08 at its upper part and a lower water outlet cavity 07 at its lower part. The lower water outlet cavity 07 has a lower water outlet connector 14 on its side, which is connected to a water pipe. The strip-shaped cultivation trough 01 also has an upper water inlet on its side. Connector 13, the upper water inlet connector 13 is connected to the water pipe. The strip-shaped cultivation trough 01 is divided into upper and lower areas. The upper area inside the strip-shaped cultivation trough 01 is the hydroponic area, and the area inside the lower water outlet chamber 07 is the water outlet area. When the device is in use, the culture solution enters the strip-shaped cultivation trough 01 through the upper water inlet connector 13. The seedlings are placed inside the strip-shaped cultivation trough 01 with their roots at the upper opening 08. The upper opening 08 of the cultivation trough has multiple inner limiting protrusions 03. The strip-shaped cultivation trough 01 has a semi-circular limiting groove 04, which limits the seedlings on one side through the inner limiting protrusion 03, so that the seedlings are evenly distributed and spaced inside the trough. The upper part of the strip-shaped cultivation trough 01 has a positioning slot 05, and the bottom of the strip-shaped cultivation trough 01 has multiple drainage holes 06. The trapezoidal partition 15 is adapted to the strip-shaped cultivation trough 01 and is inserted into the strip-shaped cultivation trough 01. The trapezoidal partition 15 is adapted to the positioning slot 05 and is inserted into the positioning slot 05. Multiple trapezoidal partitions... Plates 15 are evenly distributed inside the strip culture tank 01. The trapezoidal partition 15 has multiple filter holes 16. The trapezoidal partition 15 passes through the positioning slot 05 and is inserted into the strip culture tank 01. The trapezoidal partition 15 divides the hydroponic area in the strip culture tank 01 into multiple smaller areas of equal size. Each small area corresponds to the cultivation of one seedling. At the same time, the trapezoidal partition 15 plays a filtering role, preventing the roots of the seedlings from flowing and contaminating each culture area in soilless cultivation in agricultural planting.

[0019] Example 2:

[0020] The rotating cover plate 09 of this utility model has a cover plate side sleeve 10 on its side and a side connecting ear 02 on the side of the strip-shaped cultivation trough 01. The cover plate side sleeve 10 and the side connecting ear 02 are fitted together and the side connecting ears 02 are symmetrically arranged on both sides of the cover plate side sleeve 10. The cover plate side sleeve 10 is connected to the symmetrical side connecting ears 02 through a rotating shaft 11. The rotating cover plate 09 has multiple U-shaped slots 12. The U-shaped slots 12 and the semi-circular limiting grooves 04 have the same diameter. The rotating cover plate 09 is installed above the strip-shaped cultivation trough 01. The rotating cover plate 09 is designed to be rotatable, which makes it easy to open and take the seedlings out of the strip-shaped cultivation trough 01. When the rotating cover plate 09 is closed, the U-shaped slots 12 and the semi-circular limiting grooves 04 form a circular hole to fix the seedlings and prevent the seedlings from tilting in soilless cultivation in agricultural planting.

[0021] Example 3:

[0022] The lower surface of the rotating cover plate 09 of this invention is in contact with the upper surface of the strip-shaped culture tank 01. The strip-shaped blocking plate 17 is inserted into the lower water outlet cavity 07 and slides within it. Under normal conditions, the strip-shaped blocking plate 17 seals the drain hole 06, preventing the culture solution from falling into the lower water outlet cavity 07 in soilless cultivation. A side sliding rod 19 is connected to the side of the strip-shaped blocking plate 17, passing through the lower water outlet cavity 07 and sliding within it. An anti-detachment strip rod 20 is connected to the side of the side sliding rod 19. The strip-shaped blocking plate 17 has multiple connecting holes 18, and the bottom of the strip-shaped culture tank 01 has multiple drain holes 06, corresponding to the connecting holes 18. The sliding distance of the side sliding rod 19 within the strip-shaped blocking plate 17 is equal to the sliding displacement of the strip-shaped blocking plate 17. In soilless cultivation for agricultural planting, to prevent the strip-shaped blocking plate 17 from sliding out, the anti-detachment rod 20 can be pulled to control the movement of the strip-shaped blocking plate 17, thereby controlling the alignment and misalignment of the docking hole 18 and the drain hole 06. When it is necessary to drain the culture solution, the strip-shaped blocking plate 17 is pulled to make the docking hole 18 correspond to the drain hole 06, so that the culture solution in the strip culture tank 01 can enter the lower water outlet chamber 07 and be discharged from the lower water outlet connector 14. This device ensures the relative cleanliness of the culture solution for each seedling, and can intercept impurities such as residual roots, fallen leaves, and mud in the water, so that the culture solution is more evenly distributed around the root system, while not affecting the air circulation and promoting respiration. The strip culture tank 01 is designed with an upper and lower chamber structure. During use, the lower water outlet chamber 07 can settle impurities and some pathogens.

[0024] The installation steps of this utility model are as follows: First, connect the side sleeve 10 of the cover plate to the side connecting ear 02 through the rotating shaft 11. Then, connect the side sliding rod 19 to the strip-shaped blocking plate 17. Insert the strip-shaped blocking plate 17 into the lower water outlet cavity 07. Then, connect the side sliding rod 19 through the lower water outlet cavity 07 to the anti-detachment strip rod 20. Finally, insert the trapezoidal partition 15 through the positioning slot 05 into the strip-shaped culture tank 01.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
