Description

A sheepgrass sand culture device Technical Field

[0001] This utility model relates to the technical field of sand culture devices, specifically a sand culture device for sheepgrass. Background Technology

[0002] Sheepgrass is a perennial herb with important value in ecological protection and animal husbandry. Sheepgrass cultivation utilizes sand culture devices, which use sand as the plant growth medium and supply nutrient solution and water through a drip irrigation system. This simulates natural soil conditions, providing a suitable growing environment for sheepgrass.

[0003] Currently, when cultivating Leymus chinensis in sand culture devices, water and culture solution are dripped into the device. However, each dripping of water and culture solution does not result in complete absorption; some water and culture solution flow out from the bottom of the culture tank. Some devices directly connect the outflowing water and culture solution through pipes, but this outflow carries away some sand from the culture tank. Over time, this can cause some sand to remain in the pipes, reducing the pipes' recycling efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a sand cultivation device for sheepgrass to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand culture device for sheepgrass, comprising: a sand culture box; a sand culture trough disposed on the sand culture box; a plurality of drainage holes, all penetrating the bottom of the sand culture trough; a filter plate disposed inside the sand culture box; and a filter frame slidably engaged inside the sand culture box; wherein the drainage holes, the filter plate, and the filter frame are configured to cooperate to form a multi-stage filtration within the sand culture box.

[0006] As a further preferred embodiment of this technical solution, it further includes: a rotating frame, rotatably connected to the inner wall of the sand culture box via a rotating component, the filter plate being installed inside the rotating frame; two sliding rods, both slidably connected inside the sand culture box; two rotating rods, respectively rotatably connected to the two sliding rods, and one end of each rotating rod being rotatably connected to the bottom of the rotating frame; the sliding rods are configured to slide, so that the rotating frame can be moved within the sand culture box.

[0007] As a further preferred embodiment of this technical solution, it also includes: a plurality of return springs, which are respectively installed on the two sliding rods for rotating the frame to return to its original position.

[0008] As a further preferred embodiment of this technical solution, it also includes: a pull plate, which is fixedly connected to one end of the sliding rod.

[0009] As a further preferred embodiment of this technical solution, it also includes: an L-shaped fixing bracket, fixedly connected to the pull plate; and a limiting rod, rotatably connected to the sand culture box; the limiting rod and the L-shaped fixing bracket are configured to cooperate in limiting the position of the pull plate on the sand culture box.

[0010] As a further preferred embodiment of this technical solution, it also includes: a ramp, fixedly connected to the bottom of the sand culture box; and a pipe, fixedly connected to the sand culture box.

[0011] As a further preferred embodiment of this technical solution, it also includes: a water pump, which is fixedly installed on the sand culture box; and a drip irrigation rack, which is installed above the sand culture trough via a bracket, with the input end of the drip irrigation rack fixedly connected to the output end of the water pump.

[0012] This utility model provides a sand culture device for sheepgrass, which has the following beneficial effects:

[0013] (1) This utility model sets up a filter plate and a filter frame in the sand culture box to form a multi-stage filtration in the sand culture box. When water and nutrient solution are dripped into the sand culture tank, the water and nutrient solution flow into the sand culture box from the drain hole. The filter plate performs primary filtration and the filter frame performs secondary filtration to prevent the recycled water and nutrient solution from containing sand and to avoid sand from staying in the recycling pipe and affecting the recycling efficiency.

[0014] (2) By pulling the handle on the pull plate, the sliding rod slides in the sand culture box, thereby adjusting the tilt angle of the rotating frame. When the return spring is at its minimum contraction, the pull plate is loosened, and the reaction force of the return spring resets the rotating frame, causing the rotating frame and filter plate to move in the sand culture box. This process is repeated to clean the sand on the filter plate. The cleaned sand falls onto the filter frame. The filter frame is then removed, and the sand inside the filter frame is cleaned. This structural design prevents the filtration effect of the filter plate and filter frame from deteriorating after long-term use. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] The present invention provides a technical solution as shown in Figures 1-4. In this embodiment, a sand culture device for sheepgrass includes: a sand culture box 1; a sand culture trough 6 disposed on the sand culture box 1; a plurality of drainage holes 7, all penetrating the bottom of the sand culture trough 6; a filter plate 12 disposed inside the sand culture box 1; and a filter frame 10 slidably engaged inside the sand culture box 1. The drainage holes 7, the filter plate 12, and the filter frame 10 are configured to cooperate to form a multi-stage filtration within the sand culture box 1.

[0022] By installing filter plates 12 and filter frames 10 in the sand culture box 1, a multi-stage filtration system is formed within the sand culture box 1. When water and nutrient solution are dripped into the sand culture tank 6, the water and nutrient solution flow into the sand culture box 1 through the drain hole 7. The filter plates 12 perform primary filtration, and the filter frames 10 perform secondary filtration to prevent the recycled water and nutrient solution from containing sand and to avoid sand remaining in the recycling pipe, which would affect the recycling efficiency. After the water and nutrient solution are filtered by the filter plates 12 and filter frames 10, there may still be fine sand in the water and nutrient solution. However, fine sand has low adhesion and will flow away with the water and nutrient solution.

[0023] As shown in Figures 2-4, the system also includes: a rotating frame 11, which is rotatably connected to the inner wall of the sand culture box 1 via a rotating component; a filter plate 12 installed inside the rotating frame 11; two sliding rods 14, both slidably connected inside the sand culture box 1; two rotating rods 15, which are rotatably connected to the two sliding rods 14 respectively, and one end of the rotating rod 15 is rotatably connected to the bottom of the rotating frame 11; the sliding rods 14 are configured to slide so that the rotating frame 11 can be moved inside the sand culture box 1.

[0024] By pulling the handle on the pull plate 2, the sliding rod 14 slides inside the sand incubator 1, thereby adjusting the tilt angle of the rotating frame 11. When the return spring 16 is at its minimum contraction, the pull plate 2 is released, and the reaction force of the return spring 16 resets the rotating frame 11, causing the rotating frame 11 and the filter plate 12 to move inside the sand incubator 1. This process is repeated to clean the sand on the filter plate 12. The cleaned sand falls onto the filter frame 10. The filter frame 10 is then removed, and the sand inside the filter frame 10 is cleaned. This structural design prevents the filtration effect of the filter plate 12 and the filter frame 10 from deteriorating after long-term use. The rotating component connecting the rotating frame 11 and the sand incubator 1 can be a hinge, etc.

[0025] As shown in Figures 3 and 4, it also includes: several return springs 16, which are respectively installed on two sliding rods 14 for resetting the rotating frame 11. The structural design of the return springs 16 allows the rotating frame 11 and the filter plate 12 to be moved in the sand culture box 1 simply by pulling the pull plate 2, avoiding the need for the staff to pull the pull plate 2 back and forth.

[0026] As shown in Figures 1-4, it also includes: a pull plate 2, which is fixedly connected to one end of the sliding rod 14. The pull plate 2 is used to connect the two sliding rods 14 together. By simply pulling the pull plate 2, the two sliding rods 14 can slide simultaneously in the sand culture box 1.

[0027] As shown in Figures 1-4, it also includes: an L-shaped fixing frame 9, which is fixedly connected to the pull plate 2; and a limiting rod 8, which is rotatably connected to the sand incubator 1. The limiting rod 8 and the L-shaped fixing frame 9 are configured to cooperate in limiting the position of the pull plate 2 on the sand incubator 1. By rotating the limiting rod 8, the limiting rod 8 is rotated into the L-shaped fixing frame 9 to limit the pull plate 2 and fix it at the same time. The filter frame 10 is also fixed using this structure.

[0028] As shown in Figures 2 and 3, it also includes: a ramp 13, which is fixedly connected to the bottom of the sand culture box 1; and a pipe 3, which is fixedly connected to the sand culture box 1. The ramp 13 is used to facilitate the drainage of water and nutrient solution from the bottom of the sand culture box 1, so as to avoid water and nutrient solution remaining at the bottom of the sand culture box 1.

[0029] As shown in Figure 1, it also includes: a water pump 4, which is fixedly installed on the sand culture box 1; a drip irrigation rack 5, which is installed above the sand culture trough 6 via a bracket, and the input end of the drip irrigation rack 5 is fixedly connected to the output end of the water pump 4; through the structural design of the water pump 4 and the drip irrigation rack 5, water and nutrient solution are dripped into the sand culture trough 6 to provide nutrition for the sheep grass.

[0030] This utility model provides a sand culture device for sheepgrass, the specific working principle of which is as follows:

[0031] When cultivating sheepgrass and drip irrigation is required, turn on water pump 4 and drip irrigation frame 5 to irrigate the sheepgrass. During drip irrigation, some water and nutrient solution flow out from the bottom of sand culture tank 6. Filter plate 12 performs primary filtration, and filter frame 10 performs secondary filtration, filtering out the sand in the recovered water and nutrient solution. When used for a long time, the limitation of pull plate 2 is released by rotating limit rod 8. Pull the handle on pull plate 2, and slide rod 14 slides in sand culture box 1, thereby adjusting the tilt angle of rotating frame 11. When the return spring 16 is at its minimum contraction, the pull plate 2 is loosened. The reaction force of return spring 16 resets rotating frame 11, causing rotating frame 11 and filter plate 12 to move in sand culture box 1. Repeat this process to clean the sand on filter plate 12. The cleaned sand falls onto filter frame 10. Pull out filter frame 10 and clean the sand inside filter frame 10.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
