Technical Field

[0001] The present invention relates to the technical field of plant cultivation, in particular to a modular cultivation tank for a greenhouse. Background Art

[0002] In soilless cultivation, the components of the nutrient solution are easy to control and can be adjusted at any time. The hydroponic method of the nutrient film technique is often used, that is, a very thin layer of nutrient solution continuously circulates through the crop roots, which not only ensures the continuous supply of water and nutrients to the crops, but also continuously supplies fresh oxygen to the roots. The patent with the publication number CN220108843U discloses a modular soilless cultivation device. The liquid pump in the box can pump the hydroponic nutrient solution in the box into the pipeline, and enter the cultivation bowl through the liquid outlet, and then supply it to the flowers or vegetables fixed in the root-binding bucket for growth and absorption. However, the liquid level height needs to be monitored at all times for planting to supplement the liquid level in time. This method cannot ensure the fluidity of the nutrient solution, and the impurities shed by the plant roots are easy to accumulate and affect the quality of the nutrient solution.

[0003] Based on this, a modular cultivation tank for a greenhouse is now provided, which can eliminate the disadvantages of existing devices. Summary of the Invention

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1-7 shown, an embodiment of the present invention provides a modular cultivation tank for a greenhouse, which includes a plurality of cultivation boxes 100 fixed inside the greenhouse. A bracket assembly for installing the cultivation boxes 100 is arranged inside the greenhouse. The cultivation boxes 100 are communicated through a communication pipe 102. A nutrient cavity 103 for filling nutrient solution is arranged inside the cultivation box 100. A plurality of cultivation tank openings 101 are formed on the upper end surface of the cultivation box 100. A floating cultivation frame 200 is arranged at each cultivation tank opening 101 position. A buoyancy ring 202 for providing buoyancy is arranged at the lower end of the floating cultivation frame 200, so that the entire planting position is in a floating state and can change carefully with the water level height. Unless the nutrient solution is seriously insufficient, the roots can be kept in contact with the nutrient solution. A planting component for placing plants is arranged inside the floating cultivation frame 200. The water outlet of one of the cultivation boxes 100 is connected to a filtering component 300 through a return pipe 104. A throttle valve is arranged on the return pipe 104 to control the drainage speed. The filtering component 300 can filter the solid impurities in the nutrient solution and also helps to supplement the oxygen in the nutrient solution. The water outlet end of the filtering component 300 is communicated with a circulation pipe 401. A circulation pump 400 is arranged on the circulation pipe 401. The other end of the circulation pipe 401 is communicated with the water inlet end of one of the cultivation boxes 100. Under the action of the circulation pump 400, the nutrient solution will circulate among the plurality of cultivation boxes 100 and the filtering component 300, ensuring the cultivation quality of the nutrient solution;

[0031] The filtering component 300 includes a filtering cylinder 304. The center position at the top of the filtering cylinder 304 is communicated with the lower end of the return pipe 104. A horizontal support ring plate 308 is fixedly arranged inside the filtering cylinder 304. A filtering cone 313 for filtering the nutrient solution is fixedly arranged above the horizontal support ring plate 308. A drain port 311 communicated with the circulation pipe 401 is arranged at the bottom of the filtering cylinder 304. The impurities in the nutrient solution can be removed through the conical filtering surface. A hole cleaning component for cleaning the surface of the filtering cone 313 is also arranged inside the filtering cylinder 304. The filtering effect of the rotating column 314 can be ensured through the hole cleaning component;

[0032] The hole cleaning assembly includes a rotating column 314 located at the top of the filtering cone 313. The rotating column 314 is rotatably connected to the filtering cone 313. A cleaning scraper 305 is provided on the outer side of the upper end of the rotating column 314. The cleaning scraper 305 matches the filtering surface of the filtering cone 313. A horizontal scraper 307 is provided at the lower end of the cleaning scraper 305. The horizontal scraper 307 matches the upper end surface of the horizontal support ring plate 308. The lower end of the rotating column 314 is connected to a water storage tray 310 through a connecting shaft 309. A plurality of drainage inclined pipes 312 for draining water are arranged in an array on the outer side of the water storage tray 310. The axes of the plurality of drainage inclined pipes 312 are arranged at an acute angle with the section plane of the water storage tray 310. The reaction force generated by the water discharged from the drainage inclined pipes 312 will form a rotational torque, thereby driving the water storage tray 310 and the connecting shaft 309 to rotate. An aggregate notch 306 is formed on the outer side of the filter cylinder 304 where the horizontal support ring plate 308 is located. A side box 302 is fixedly provided on the outer side of the filter cylinder 304 where the aggregate notch 306 is located. A box door 301 is detachably provided at the outer end of the side box 302. A slag discharge pipe 303 for draining water is provided at the bottom of the side box 302. A discharge valve is provided on the slag discharge pipe 303. During actual use, the water discharged from the return pipe 104 will flow along the surface of the filtering cone 313 to complete filtration. After the liquid enters the water storage tray 310, it will be discharged along the drainage inclined pipes 312. The rotational torque generated by the drainage will drive the water storage tray 310 and the connecting shaft 309 to rotate. The connecting shaft 309 drives the rotating column 314 to rotate. The rotating column 314 drives the cleaning scraper 305 and the horizontal scraper 307 to rotate, thereby driving the impurities to move. Under the action of centrifugal force, the impurities will stay in the side box 302, and the slag can be discharged by opening the slag discharge pipe 303 later;

[0033] The planting component includes a cultivation inner frame 201. A support outer ring 205 is provided on the outer side of the cultivation inner frame 201. A support inner ring 204 for supporting the support outer ring 205 is provided on the inner wall of the floating cultivation frame 200. In this way, the support inner ring 204 can provide a support force for the support outer ring 205, so that the cultivation inner frame 201 is stuck inside the floating cultivation frame 200, and it is also convenient to separate the cultivation inner frame 201 later. The bottom of the cultivation inner frame 201 is a tapered structure in a contracted shape, and a plurality of root grooves 203 are distributed on the tapered structure. A bottom opening 207 is also provided at the bottom of the cultivation inner frame 201. A stem support frame 206 is provided inside the root grooves 203. The root grooves 203 are used to facilitate the roots to extend into the nutrient solution, and the stem support frame 206 is used to support the stem;

[0034] Scale bars are provided on the outer side of the floating cultivation frame 200 to actually control the overall weight of the plants. Observation windows are provided on the outer side of the cultivation box 100, and scale bars are provided on the observation windows to control the height of the nutrient solution;

[0035] A plurality of ear pulls 208 are symmetrically arranged at the upper end of the cultivation inner frame 201 to apply force to the cultivation inner frame 201:

[0036] Both the cultivation inner frame 201 and the floating cultivation frame 200 here are made of PVC material, which helps to reduce costs;

[0037] A storage tank communicating with the circulation pipe 401 can also be arranged at the lower end of the filtering component 300 to store sufficient nutrient solution. A supplementary pipe is arranged on the storage tank to supplement the nutrient solution in a timely manner.

[0038] Working principle: In actual use, the nutrient solution is continuously circulated between the cultivation tank 100 and the filtering component 300 through the circulation pump 400, so that the nutrient solution continuously circulates. The impurities in the nutrient solution are continuously filtered in the filtering component 300 to ensure the quality of the nutrient solution. Specifically as follows:

[0039] The water discharged from the return pipe 104 will flow along the surface of the filtering cone 313 to complete filtration. After the liquid enters the water storage tray 310, it will be discharged along the drainage inclined pipe 312. The rotational torque generated by the drainage will drive the water storage tray 310 and the connecting shaft 309 to rotate. The connecting shaft 309 drives the rotating column 314 to rotate, and the rotating column 314 drives the cleaning scraper 305 and the horizontal scraper 307 to rotate, thereby driving the impurities to move. Under the action of centrifugal force, the impurities will stay in the side box 302, and the slag can be discharged by opening the slag discharge pipe 303 later;

[0040] When planting, just pull out the cultivation inner frame 201 from the floating cultivation frame 200, then fix the plant seedlings on the stem support frame 206, extend the plant roots to the position of the root strip groove 203, and then put the cultivation inner frame 201 into the floating cultivation frame 200. At this time, the support inner ring 204 will support the support outer ring 205, and the root position will extend into the nutrient solution. As the plant grows, its weight will increase, which can be directly obtained through the scale on the outside of the floating cultivation frame 200. Here, the floating design is adopted to ensure that the roots can directly contact the nutrient solution.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
