Description

Technical Field

[0001] This invention relates to the field of soilless cultivation equipment technology, specifically to a soilless cultivation equipment for vegetables with adjustable support frame. Background Technology

[0002] Facility vegetable production is a method of producing off-season vegetables in winter and spring in facilities such as multi-span greenhouses, solar greenhouses, and plastic greenhouses. Compared with open field cultivation, facility soil is in a relatively closed space. It is affected by environmental conditions and agronomic activities such as high temperature, humidity and evaporation, high fertilizer and water input, and high multiple cropping index. The physical, chemical and biological properties of facility soil change drastically and in a complex and diverse way, often leading to soil quality problems such as secondary salinization, nutrient imbalance, accumulation of harmful elements, and deterioration of microbial community.

[0003] Currently, the problems in facility horticulture production caused by soil deterioration are very serious. Due to the uncontrollable soil environment, the yield and quality of facility vegetables grown in soil are low, which increasingly fails to meet people's requirements for high-quality agricultural products. Soilless cultivation is an effective way to solve this problem. It uses a substrate instead of soil, and the vegetable roots are confined in an artificial environment. For example, a soilless cultivation device for facility vegetables with soil ridging and burying in a trench (announcement number CN212344865U) automatically replenishes nutrient solution through liquid level difference. This structure is simple and has a certain effect, but there is a problem. Since the cultivation box inevitably leaks sand, when the soil substrate blocks the pipe inlet and outlet, water pressure cannot be used to send water into the cultivation box. At this time, the only solution is to clean the pipe. Therefore, the device requires regular manual maintenance, which is inefficient. In addition, the device lacks a support for adjustment according to crop growth, and cannot correct the growth direction of the crop.

[0004] Therefore, we propose a soilless cultivation device for vegetables with adjustable support frame to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a soilless cultivation device for vegetables with an adjustable support frame, in order to solve the problems mentioned in the background art, such as the easy blockage of pipe inlet and outlet of current soilless cultivation devices on the market, which prevents water pressure from delivering nutrient solution into the cultivation box, the need for regular manual maintenance, low efficiency, and the lack of a support frame that can be adjusted according to crop growth, making it impossible to correct the growth direction of the crops.

A dual-axis motor is fixedly provided on the side of the liquid storage cylinder, and one end of the dual-axis motor is connected to the crank plate through a rotating shaft. The crank plate is connected to the piston through a crankshaft.

[0008] One end of the dual-shaft motor is connected to the first stirring shaft inside the nutrient solution storage tank via a first belt.

[0012] As a preferred embodiment of the present invention, the nutrient solution storage tank is mounted on the upper end of the base plate via a first bracket, and a piston box is mounted on the side of the storage cylinder via a second bracket. The upper end of the nutrient solution storage tank is provided with a lid, and the storage cylinder is connected to a drain valve.

[0013] As a preferred embodiment of the present invention, the surface of the nutrient solution storage tank is provided with a liquid level window, and the side of the liquid level window is provided with scale lines, and the first connecting pipe is connected to the valve.

[0014] As a preferred embodiment of the present invention, the side of the cultivation box is provided with a limiting block, and the inside of the liquid storage cylinder is provided with a limiting groove, and the limiting groove and the limiting block cooperate with each other.

[0015] As a preferred embodiment of the present invention, multiple second stirring shafts are provided, and a belt pulley is provided at the bottom of the second stirring shaft. The second stirring shafts are connected to each other by belt pulley and second belt drive.

[0016] As a preferred embodiment of the present invention, one end of the second connecting pipe is connected to the shower head, and the shower head is detachable from the upper end of the second connecting pipe.

When the annular plate needs to be disassembled for cleaning the first filter plate, the annular plate is pulled up by hand, causing the locking block at the lower end of the first filter plate to disengage from the stop block, thus allowing the locking block to be pulled out of the slot, which is very convenient. By setting an electric push rod and a plant rack at the upper end of the cultivation box, the height of the plant rack can be easily adjusted by the electric push rod, thereby supporting the crops and preventing them from growing crookedly. The addition of a base plate and casters makes it easy for users to push and transport the device, increasing its practicality. Attached Figure Description

[0030] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Please see Figure 1-7 This invention provides a technical solution: a soilless cultivation device for vegetables with adjustable support frame, comprising a liquid storage cylinder 1 and a nutrient solution storage tank 6 connected to the liquid storage cylinder 1. A cultivation box 31 is installed in the liquid storage cylinder 1, and the nutrient solution storage tank 6 supplies liquid to the liquid storage cylinder 1. A second filter plate 36 is installed at the bottom of the liquid storage cylinder 1. A base plate 2 is installed at the bottom of the liquid storage cylinder 1, and casters 3 are installed at the bottom of the base plate 2. The surface of the casters 3 is provided with anti-slip texture. The nutrient solution storage tank 6 is installed on the upper end of the base plate 2 via a first support 5. A piston box 12 is installed on the side of the liquid storage cylinder 1 via a second support 13, and a box is installed at the upper end of the nutrient solution storage tank 6. The cover 7 is connected to the liquid storage tank 1 and the drain valve 41. The side of the cultivation box 31 is provided with a limiting block 32, and the inside of the liquid storage tank 1 is provided with a limiting groove 33. The limiting groove 33 and the limiting block 32 cooperate with each other. When in use, open the box cover 7 at the top of the nutrient solution storage tank 6 and pour in an appropriate amount of nutrient solution into the nutrient solution storage tank 6. Then insert the cultivation box 31 into the liquid storage tank 1, ensuring that the limiting block 32 on the surface of the cultivation box 31 is engaged with the limiting groove 33 inside the liquid storage tank 1 to prevent the cultivation box 31 from rotating in the liquid storage tank 1 due to subsequent movement. Since the base plate 2 and universal wheels 3 are provided, it is convenient for users to push and transport the device, which increases its practicality.

[0032] An annular plate 23 is installed at the lower part of the liquid storage cylinder 1 via a snap-fit ​​structure, and the annular plate 23 is connected to the first filter plate 24. The snap-fit ​​structure includes a snap block 25, which is located at the lower end of the annular plate 23. The liquid storage cylinder 1 has a slot 26 inside that matches the shape of the snap block 25. The liquid storage cylinder 1 also has an inner groove 27 inside, in which a stop block 28 is slidably installed. The stop block 28 is connected to a spring 29 and engages with the snap block 25. An electric push rod is installed at the upper end of the cultivation box 31. 34, and the electric push rod 34 is connected to the plant rack 35; when it is necessary to disassemble the ring plate 23 to clean the first filter plate 24, pull the ring plate 23 up by hand, so that the locking block 25 at the lower end of the first filter plate 24 is disengaged from the stop block 28, so that the locking block 25 can be pulled out from the slot 26, which is very convenient. By setting the electric push rod 34 and the plant rack 35 at the upper end of the cultivation box 31, the height of the plant rack 35 can be easily adjusted by the electric push rod 34, thereby supporting the crop and preventing the crop from growing crookedly;

[0033] A control panel 4 is provided on the surface of the storage tank 1, and the lower end of the nutrient solution storage tank 6 is connected to the piston box 12 through a first connecting pipe 10. A liquid level window 8 is provided on the surface of the nutrient solution storage tank 6, and a scale line 9 is provided on the side of the liquid level window 8. The first connecting pipe 10 is connected to the valve 11, and the piston box 12 is provided on the side of the storage tank 1. The first connecting pipe 10 is connected to the piston box 12, and the other end of the piston box 12 is connected to the storage tank 1 through a second connecting pipe 21. One end of the second connecting pipe 21 is connected to the shower head 22, and the shower head 22 is detachable from the upper end of the second connecting pipe 21. A dual-axis motor 14 is fixedly provided on the side of the storage tank 1, and one end of the dual-axis motor 14 is connected to the rotating shaft 15. The dual-axis motor 14 is connected to the crankshaft 18, which is connected to the piston 20 via the crankshaft 19. One end of the dual-axis motor 14 is connected to the first stirring shaft 17 inside the nutrient solution storage tank 6 via the first belt 16. The dual-axis motor 14 is connected to the first gear 30 via the rotating shaft 15, and the second stirring shaft 37 is rotatably connected inside the cultivation box 31. One end of the second stirring shaft 37 is connected to the second gear 38, which meshes with the first gear 30. Multiple second stirring shafts 37 are provided, and a pulley 39 is provided at the bottom of each second stirring shaft 37. The second stirring shafts 37 are connected to each other via the pulley 39 and the second belt 40. After setting the program on the control panel 4, the dual-axis motor 14 will periodically... When the dual-shaft motor 14 starts, it drives the first stirring shaft 17 to rotate via the first belt 16. The first stirring shaft 17 stirs and mixes the nutrient solution inside the nutrient solution storage tank 6 to prevent sedimentation. At the same time, the rotating shaft 15 drives the first gear 30 to rotate. The first gear 30 meshes with the second gear 38, thereby driving the second stirring shaft 37 to rotate. The second stirring shaft 37 loosens the soil inside the cultivation box 31 to prevent soil clumping, which would affect the absorption of nutrient solution. Furthermore, when the rotating shaft 15 rotates, it drives the crank plate 18 to rotate. The crank plate 18 drives the piston 20 to reciprocate in the piston box 12 via the crankshaft 19. Due to the first connecting pipe 10 and the second connecting pipe 21... Each part is equipped with a one-way valve, which causes intermittent high and low pressure to be generated inside the piston box 12. This allows the nutrient solution inside the nutrient solution storage tank 6 to be drawn into the piston box 12 through the first connecting pipe 10. As the piston 20 pushes, the nutrient solution is squeezed into the storage cylinder 1 through the second connecting pipe 21. The nutrient solution is absorbed and consumed by the organic substrate in the cultivation box 31 through the first filter plate 24 and the second filter plate 36. The first filter plate 24 and the second filter plate 36 can block the soil sand and gravel, preventing excessive substrate from flowing out of the cultivation box 31 and ensuring that the crops can grow normally. When there is too much nutrient solution in the storage cylinder 1, the excess nutrient solution can be released by opening the drain valve 41 to prevent the crops from being overwatered.

[0034] Working principle: First, open the lid 7 at the top of the nutrient solution storage tank 6 and pour in an appropriate amount of nutrient solution. Then, insert the cultivation box 31 into the storage cylinder 1, ensuring that the limiting block 32 on the surface of the cultivation box 31 engages with the limiting groove 33 inside the storage cylinder 1 to prevent the cultivation box 31 from rotating inside the storage cylinder 1 due to subsequent movement. After setting the program on the control panel 4, the dual-shaft motor 14 will start at regular intervals. When the dual-shaft motor 14 starts, it will drive the first stirring shaft 17 to rotate via the first belt 16. The first stirring shaft 17 stirs and mixes the nutrient solution inside the nutrient solution storage tank 6 to prevent sedimentation. At the same time, the rotating shaft 15 will drive the first gear 30 to rotate. The first gear 30 meshes with the second gear 38, thereby driving the second stirring shaft 37 to rotate. The second stirring shaft 37 stirs the soil inside the cultivation box 31. Loosening the soil prevents it from clumping and affecting nutrient solution absorption. As the rotating shaft 15 rotates, it drives the crank plate 18 to rotate. The crank plate 18, via the crankshaft 19, drives the piston 20 to reciprocate within the piston box 12. Since both the first connecting pipe 10 and the second connecting pipe 21 are equipped with one-way valves, intermittent high and low pressures are generated inside the piston box 12. This draws nutrient solution from the nutrient solution storage tank 6 into the piston box 12 through the first connecting pipe 10. With the pushing force of the piston 20, the nutrient solution is squeezed through the second connecting pipe 21 into the storage cylinder 1. The nutrient solution is absorbed and consumed by the organic substrate in the cultivation box 31 through the first filter plate 24 and the second filter plate 36. The first filter plate 24 and the second filter plate 36 can block soil sand and gravel, preventing excessive substrate outflow from the cultivation box 31 and ensuring normal crop growth.

[0035] When it is necessary to disassemble the annular plate 23 to clean the first filter plate 24, pull the annular plate 23 upwards by hand, so that the locking block 25 at the lower end of the first filter plate 24 disengages from the stop block 28, and the locking block 25 can be pulled out from the slot 26, which is very convenient. By setting the electric push rod 34 and the plant rack 35 at the upper end of the cultivation box 31, the height of the plant rack 35 can be easily adjusted by the electric push rod 34, thereby supporting the crop and preventing the crop from growing crookedly.

[0036] Because a liquid level window 8 is provided on the surface of the nutrient solution storage tank 6, and the scale line 9 on the surface of the nutrient solution storage tank 6 allows the remaining amount of nutrient solution inside the nutrient solution storage tank 6 to be observed from the outside. When there is too much nutrient solution inside the storage cylinder 1, the excess nutrient solution can be released by opening the drain valve 41 to prevent the crops from being flooded. Because a base plate 2 and casters 3 are provided, the device can be easily pushed and transported by the user, which increases its practicality.

[0037] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
