Description

Technical Field

[0001] This utility model relates to the field of vegetable planting equipment technology, and in particular to a vegetable hydroponic device that can recycle nutrient solution. Background Technology

[0002] Hydroponics, as an advanced soilless cultivation technology, enables crop growth by directly providing nutrient solution to plant roots. Due to its advantages such as saving land, high water and fertilizer utilization rate, and short growth cycle, it is widely used in modern agricultural production. In large-scale vegetable hydroponic systems, nutrient solution is usually recycled in order to save costs and resources.

[0003] During the circulation of nutrient solution, it is inevitable that plant roots, residual cultivation substrate, and other solid impurities will be mixed in. In order to prevent these impurities from damaging the circulation pump or clogging the pipes and affecting the normal supply of nutrient solution, existing technologies usually install filtration devices, such as filter screens, on the path of nutrient solution return to the storage tank to intercept and remove these impurities. This is crucial for maintaining the stable operation of the system.

[0004] However, as the equipment runs for a long time, impurities trapped by the filter will accumulate on its surface, gradually causing the filter to become clogged. Once the filter is clogged, it will seriously affect the return speed and circulation efficiency of the nutrient solution, and may even cause the circulation to be interrupted, preventing the vegetable roots from receiving timely nutrient supply and thus affecting their normal growth. At present, the main way to solve the problem of filter clogging is to carry out regular manual maintenance. Operators need to stop the equipment operation, disassemble the filter for cleaning, and then reinstall it. This process is not only cumbersome and increases a lot of labor intensity and time costs, but also reduces the automation level and production continuity of the entire hydroponic system. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vegetable hydroponic device that can recycle nutrient solution, aiming to improve the problems of easy clogging of the filter screen and the need for frequent manual cleaning, which leads to complicated maintenance in the existing circulating hydroponic device.

Its output end is rotatably connected to one end of a connecting rod. The other end of the connecting rod is rotatably and slidably connected to the support rod through a sliding column. The bottom of the support rod is fixedly connected to a brush bristle, and the bottom of the support rod is also connected to a limit plate. The limit plate is slidably fitted into a limit frame fixedly connected to the inner wall of the nutrient tank, realizing automatic reciprocating cleaning of the filter screen.

[0007] Preferably, the hydroponic system includes multiple hydroponic buckets and hydroponic hanging baskets respectively installed in the multiple hydroponic buckets.

[0008] Preferably, the nutrient box has an insertion port, and the bottom of the hydroponic bucket is inserted into the insertion port through a connecting tube.

[0009] Preferably, the circulation mechanism also includes a coil, and the output end of the circulation pump is connected to the hydroponic mechanism through the coil.

[0010] Preferably, the circulation mechanism also includes an outlet pipe, and the input end of the circulation pump is connected to the interior of the nutrient tank through the outlet pipe.

[0011] Preferably, the filtration mechanism further includes a slide rail arranged in a vertical direction, and the filter screen is detachably slidably connected to the slide rail.

[0012] Preferably, the support rod has a groove extending along its length, and the sliding column is slidably disposed in the groove.

It achieves the technical effect of automatic online cleaning of filter screens, reducing the intensity and frequency of manual maintenance, and improving the automation level of equipment.

[0015] 2.

[0019] 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.

[0020] Reference Figures 1-5The present invention provides an embodiment of a vegetable hydroponic device that can recycle nutrient solution, including a support frame 1, a hydroponic mechanism 2 set on the support frame 1, a circulation mechanism 3, a filtration mechanism 4 set in the nutrient tank 301 of the circulation mechanism 3, and a cleaning mechanism 5. The support frame 1 provides the installation and support foundation for the entire device. The hydroponic mechanism 2, the circulation mechanism 3, the filtration mechanism 4 and the cleaning mechanism 5 work together to achieve the recycling of nutrient solution and self-cleaning effect. The cleaning mechanism 5 is installed inside the nutrient tank 301 and includes a waterproof servo motor 501, a connecting rod 502, a sliding column 503, a support rod 504, brush bristles 505, a limiting frame 506, and a limiting plate 507. The body of the waterproof servo motor 501 is fixedly connected to the outside of the nutrient tank 301, and its output end extends into the interior of the nutrient tank 301 through the wall panel. One end of the connecting rod 502 is rotatably connected to the output end of the waterproof servo motor 501. A sliding column 503 is slidably arranged inside the support rod 504, and the sliding column 503 is rotatably connected to the other end of the connecting rod 502. Brush bristles 505 are fixedly connected to the bottom of the support rod 504. 05. The brush bristles 505 are used to brush the filter screen 402 in the filter mechanism 4. In order to ensure the stability of the movement of the support rod 504, a limiting frame 506 is fixedly connected to the inner wall of the nutrient tank 301. At the same time, a limiting plate 507 is connected to the bottom of the support rod 504. The limiting plate 507 is slidably fitted in the limiting frame 506. When the waterproof servo motor 501 works, its output end drives the connecting rod 502 to swing back and forth. Then, through the sliding column 503, the support rod 504 is driven to move back and forth horizontally under the guidance and restriction of the limiting frame 506, thereby driving the brush bristles 505 to continuously clean the surface of the filter screen 402. The hydroponic mechanism 2 includes multiple hydroponic containers 201 and hydroponic hanging baskets 202 respectively installed inside the multiple hydroponic containers 201. The multiple hydroponic containers 201 are evenly placed on the support 1. The nutrient tank 301 in the circulation mechanism 3 has an inlet 303. The bottom of each hydroponic container 201 is connected to the corresponding inlet 303 through a connecting pipe 203, thereby constructing a channel for the nutrient solution to flow back from the hydroponic container 201 to the nutrient tank 301. The nutrient solution is supplied by a circulation pump. The circulation pump 304, the outlet pipe 305, and the coil 302 together constitute a circulating pump. The input end of the circulating pump 304 is connected to the internal fluid of the nutrient tank 301 through the outlet pipe 305, and is used to draw nutrient solution from the nutrient tank 301. The output end of the circulating pump 304 is connected to the coil 302. The coil 302 further branches and connects to multiple hydroponic buckets 201, so as to evenly deliver the pressurized nutrient solution to each hydroponic bucket 201 to nourish the vegetables placed in the hydroponic hanging basket 202. To facilitate the installation and replacement of the filter screen 402, the filter mechanism 4 also includes a slide rail 401 arranged in the vertical direction. The filter screen 402 is detachably slidably connected to the slide rail 401. In order to make the swing of the connecting rod 502 stably converted into the translational motion of the support rod 504, a slide groove extending along its length is provided on the support rod 504. The slide column 503 is slidably arranged in the slide groove. In order to ensure that the cleaning mechanism 5 can effectively clean the filter screen 402, the working surface of the brush bristles 505 is in contact with the surface of the filter screen 402.

[0021] Working principle: During hydroponics, vegetables are placed in the hydroponic basket 202 of the hydroponic mechanism 2, which is then placed in the hydroponic bucket 201 supported by the bracket 1. The circulation mechanism 3 starts working, and the circulation pump 304 draws nutrient solution from the nutrient tank 301 through the outlet pipe 305. After pressurization, it is pumped into the coil 302. The nutrient solution is transported to each hydroponic bucket 201 through the coil 302 to supply the nutrients needed for vegetable growth. The nutrient solution flowing through the hydroponic bucket 201 flows back to the nutrient tank 301 through the connecting pipe 203 at its bottom and the inlet 303 on the nutrient tank 301. During the return flow, the nutrient solution passes through the filter screen 402, and impurities are intercepted, thus completing one cycle of nutrient solution circulation and filtration. When the filter screen 402 accumulates impurities due to prolonged filtration and requires cleaning, the cleaning mechanism 5 is activated. The waterproof servo motor 501 drives the connecting rod 502 connected to its output end to swing back and forth. Since the other end of the connecting rod 502 is connected to the support rod 504 through the sliding column 503, the swing motion of the connecting rod 502 is converted into the reciprocating linear motion of the support rod 504. This linear motion is guided and limited by the limiting frame 506 fixed to the inner wall of the nutrient tank 301 and the limiting plate 507 connected to the bottom of the support rod 504 and sliding in the limiting frame 506, ensuring the stability of the motion. As the support rod 504 reciprocates, the bristles 505 fixed at its bottom repeatedly brush the surface of the filter screen 402, removing the attached impurities, realizing online automatic cleaning of the filter screen 402, and ensuring the smooth flow of the nutrient solution circulation path.
