Technical Field

[0001] The invention belongs to the technical field of vegetation planting, and in particular relates to a circulating agricultural planting device. Background Art

[0002] In the circulating agricultural planting system, there is a circulating hydroponic planting method, which uses a water pump to extract the nutrient solution in the nutrient solution storage tank and transport it to the cultivation container through a pipe. The nutrient solution comes into contact with the plant roots in the cultivation container to provide water, nutrients and oxygen for the plants. After the plant roots absorb the nutrients and water in the nutrient solution, the remaining nutrient solution flows back to the nutrient solution storage tank through the return pipe, forming a circulation loop. In this process, the filter device will filter the returned nutrient solution to remove impurities and harmful substances therein to ensure the cleanliness and purity of the nutrient solution to meet the needs of plant growth.

[0003] In some existing circulating agricultural planting devices, there may be some necrotic rhizomes in the root of the vegetation. These necrotic rhizomes exist in the nutrient solution or in the rhizomes. Since the nutrient solution is rich in nutrients, the necrotic rhizomes will generate a lot of bacteria, affecting the growth of the vegetation. Summary of the invention

[0007] Preferably, the volute pipe is fixedly connected to a liquid separation inlet pipe, and the liquid separation inlet pipes are jointly fixedly connected to a liquid separation pipe. The inner diameter of the lower side of the root growth tube is smaller than the inner diameter of the upper side, and the diameter of the position of the volute pipe connected to the liquid separation inlet pipe gradually decreases as the volute pipe bends.

[0008] Preferably, the liquid outlet baffle is fixedly connected to the flowing liquid partition plate, and the inner bottom surface of the cultivation frame is flush with the inner bottom surface of the partitioned liquid outlet pipe.

[0010] Preferably, an impurity interception net is fixedly connected to a side of the impurity interception slideway away from the separated liquid outlet pipe, and the impurity interception net is provided with holes for the nutrient solution to flow through.

[0011] Preferably, a circulation connection pipe is fixedly connected to the lower side of the partitioned liquid outlet pipe, and the circulation connection pipe is fixedly connected to the liquid separation pipe at the lower side, and a discharge pipe is fixedly connected to the lower side of the lowermost partitioned liquid outlet pipe.

[0014] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a circulating agricultural planting device,

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention cooperates with structures such as a volute pipe and a root growth tube. When the nutrient solution flows into the volute pipe through the liquid separation pipe and the root growth tube, the nutrient solution is guided by the arc of the volute pipe to flow into the root growth tube in a circumferential direction. The nutrient solution is guided by the guide vanes to form a vortex in the root growth tube. The vortex of the nutrient solution contacts the rhizomes of the plants in the root growth tube, thereby providing nutrition for the rhizomes of the plants. At the same time, the vortex of the nutrient solution has a plastic effect on the rhizomes of the plants, and the necrotic rhizomes in the rhizomes of the plants are brought out of the root growth tube through the vortex of the nutrient solution, thereby preventing the necrotic rhizomes from affecting the growth of the plants.

[0017] The present invention cooperates with structures such as a separated liquid outlet pipe and a mass-liquid separation net, and transports necrotic rhizomes into the separated liquid outlet pipe with nutrient solution, isolates necrotic plant rhizomes or other impurities on the mass-liquid separation net through the through holes on the mass-liquid separation net, and the nutrient solution flows under the mass-liquid separation net. By regulating the amount of nutrient solution intermittently pumped into the liquid separation pipe by a circulating water pump, the effect of the nutrient solution vortex in the root growth tube on the plant rhizomes is intermittently enhanced. At the same time, when the nutrient solution passes through the separated liquid outlet pipe, the amount of flowing nutrient solution is greater than the amount that can be led downward by the circulating connecting pipe, and then the excess nutrient solution pushes the necrotic rhizomes or impurities on the mass-liquid separation net to flow into the impurity interception chute, and then is intercepted by the impurity interception net, so that the impurities and necrotic plant rhizomes gather in the impurity interception chute for easy cleaning.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown, the present invention provides a circulating agricultural planting device, a circulating agricultural planting device, comprising a nutrient solution tank 10, the nutrient solution tank 10 is fixedly connected with a symmetrically distributed stable bracket 101, the stable bracket 101 is fixedly connected with a short liquid outlet channel 504, the short liquid outlet channel 504 is fixedly connected with a triangular bracket 102, the triangular bracket 102 is fixedly connected with a sealing plate 202, the sealing plate 202 is fixedly connected with a cultivation frame 20, and the cultivation frame 20 is distributed in an array.

[0028] Among them, the cultivation frame 20 is fixedly connected with a vegetation cultivation tube 40 distributed in an array, the cultivation frame 20 is fixedly connected with a flowing liquid partition plate 203, the flowing liquid partition plate 203 is fixedly connected with a root growth tube 401 distributed in an array corresponding to the vegetation cultivation tube 40, the lower end of the vegetation cultivation tube 40 and the upper end of the root growth tube 401 are fixedly connected with a sealing ring 4021, the sealing rings 4021 are fixedly connected with guide vanes 4022 distributed in a circumferential array, and the sealing rings 4021 are fixedly connected with a volute pipe 402;

[0029] A liquid outlet baffle 201 is fixedly connected to one side of the cultivation frame 20 away from the sealing plate 202 . The cultivation frame 20 and the liquid outlet baffle 201 are fixedly connected to a partitioned liquid outlet pipe 50 . The partitioned liquid outlet pipe 50 is fixedly connected to an impurity intercepting slide 501 .

[0030] The above method is adopted: first, the vegetation is planted in the vegetation cultivation tube 40, and as the nutrient solution is transported from the nutrient solution tank 10 to the volute pipe 402, the nutrient solution flows into the root growth tube 401 through the arc pipe of the volute pipe 402 and the guide vane 4022, and then the nutrient solution forms a vortex in the root growth tube 401, and by controlling the amount of nutrient solution entering the volute pipe 402, the range of the vortex can be controlled to control the growth of the rhizomes of the vegetation, and at the same time, in conjunction with the vortex of the nutrient solution, impurities or some necrotic rhizomes at the rhizomes of the vegetation are taken away together through the vortex of the nutrient solution to prevent the necrotic rhizomes from rotting and affecting the growth of the vegetation. The flow of the nutrient solution drives the necrotic rhizomes and some impurities to flow into the separation outlet pipe 50, waiting for subsequent cleaning.

[0031] like Figure 3 and 4As shown, the volute pipe 402 is fixedly connected to the liquid separation inlet pipe 4023, and the liquid separation inlet pipe 4023 is jointly fixedly connected to the liquid separation pipe 303. The inner diameter of the lower side of the root growth tube 401 is smaller than the inner diameter of the upper side. The diameter of the position of the volute pipe 402 connected to the liquid separation inlet pipe 4023 gradually decreases as the volute pipe 402 bends.

[0032] The above method is adopted: since the curvature of the volute pipe 402 gradually decreases, the speed of the nutrient solution flowing into the root growth tube 401 through the guide vane 4022 is ensured to be consistent, and since the inner diameter of the root growth tube 401 decreases from top to bottom, the vortex formed by the nutrient solution gradually shrinks, and then the shape of the rhizomes of the vegetation is controlled by the vortex of the nutrient solution to ensure that the rhizomes of the vegetation maintain a fixed shape in the root growth tube 401, making the harvesting of the vegetation more convenient. At the same time, when the rhizomes of the vegetation are too long, they can gradually converge downward with the vortex, and the power of the nutrient solution vortex is enhanced, so that the overly long rhizomes can be repaired to a certain extent.

[0033] like Figure 1 , 5 As shown in FIG. 6 , the liquid outlet baffle 201 is fixedly connected to the flowing liquid partition plate 203 , and the inner bottom surface of the cultivation frame 20 is flush with the inner bottom surface of the partition liquid outlet pipe 50 .

[0034] A plasma-liquid separation net 502 is fixedly connected in the separated liquid outlet pipe 50 . A through hole is provided on the plasma-liquid separation net 502 for only passing the nutrient solution. A slope is provided on one side of the plasma-liquid separation net 502 close to the liquid outlet baffle 201 .

[0035] An impurity interception net 5011 is fixedly connected to the side of the impurity interception slide 501 away from the separation liquid outlet pipe 50, and the impurity interception net 5011 is provided with holes for the nutrient solution to flow.

[0036] A circulation connection pipe 304 is fixedly connected to the lower side of the partitioned liquid outlet pipe 50 , and the circulation connection pipe 304 is fixedly connected to the lower liquid separation pipe 303 . A discharge pipe 305 is fixedly connected to the lower side of the lowermost partitioned liquid outlet pipe 50 .

[0037] The above method is adopted: when the nutrient solution carries the necrotic rhizomes and flows into the separation outlet pipe 50, the impurities and necrotic rhizomes are brought into the mass-liquid separation net 502 together with the inclined surface of the mass-liquid separation net 502. Since the through holes of the mass-liquid separation net 502 are small, the rhizomes cannot fall down and can only flow on the mass-liquid separation net 502 along with the flow of the nutrient solution, and then flow into the impurity interception chute 501, and are intercepted by the impurity interception net 5011 again, so that the impurities and necrotic rhizomes are gathered in the impurity interception chute 501, which is convenient for cleaning.

[0038] At the same time, the nutrient solution that penetrates into the lower side of the plasma-liquid separation net 502 through the through holes of the plasma-liquid separation net 502 flows into the liquid separation pipeline 303 of the next layer through the circulation connecting pipe 304. Since the nutrient solution preferentially flows through the plasma-liquid separation net 502 and the circulation connecting pipe 304 to the liquid separation pipeline 303 of the next layer, impurities and necrotic rhizomes on the plasma-liquid separation net 502 may be accumulated on the plasma-liquid separation net 502. By enhancing the flow rate of the nutrient solution, the amount of nutrient solution passing through the separated liquid outlet pipeline 50 is greater than the amount flowing in the circulation connecting pipe 304, thereby pushing the impurities and necrotic rhizomes into the impurity interception slide 501 to wait for processing.

[0039] like Figure 7 As shown, a long liquid outlet channel 503 is fixedly connected to a stable bracket 101 on the nutrient solution tank 10 away from the short liquid outlet channel 504, a cross plate bracket 103 is fixedly connected to the long liquid outlet channel 503, the long liquid outlet channel 503 is fixedly connected to the impurity intercepting slide 501, the cross plate bracket 103 is fixedly connected to the sealing plate 202, and the short liquid outlet channel 504 is fixedly connected to the cross plate bracket 103.

[0040] The above method is adopted: the nutrient solution flowing through the impurity interception slide 501 flows into the nutrient solution box 10 through the long liquid outlet channel 503, and the cultivation frame 20 is fixed by the horizontal plate bracket 103 on the long liquid outlet channel 503 and the short liquid outlet channel 504 to ensure the spacing and stability of the cultivation frame 20 and ensure that the nutrient solution circulation is not wasted.

[0041] like Figure 7 As shown, a circulating water pump 30 is fixedly connected inside the nutrient solution box 10 , a liquid inlet pipe 302 is fixedly connected to the circulating water pump 30 , an upper liquid pipe 301 is fixedly connected to the upper side of the circulating water pump 30 , and the upper liquid pipe 301 is fixedly connected to the uppermost liquid separation pipe 303 .

[0042] The above method is adopted: the nutrient solution in the nutrient solution box 10 is pumped into the upper liquid pipe 301 through the circulating water pump 30 to the uppermost liquid distribution pipe 303, and the nutrient solution in the nutrient solution box 10 is pumped into the circulating water pump 30 through the liquid inlet pipe 302, so that the nutrient solution is circulated in the entire device.

[0043] The working principle and use process of the present invention:

[0044] Embodiment 1:

[0045] First, the operator injects the nutrient solution into the nutrient solution box 10, and then starts the circulating water pump 30, pumps the nutrient solution in the nutrient solution box 10 into the circulating water pump 30 through the liquid inlet pipe 302, and then pumps the nutrient solution into the upper liquid separation pipe 303 through the upper liquid pipe 301, and then transports the nutrient solution to the volute pipe 402 through the separation pipe 303. The order in which the nutrient solution flows through the separation pipe 303 makes the order in which the nutrient solution flows into the volute pipe 402 consistent, and then the nutrient solution flows through the entire volute pipe 402, and guides the nutrient solution into the root growth tube 401 through the guide vane 4022. As the inner diameter of the volute pipe 402 is reduced, The nutrient solution flows into the root growth tube 401 through the guide vane 4022 at a uniform speed. At the same time, the nutrient solution is guided by the guide vane 4022 to form a vortex in the root growth tube 401. The inner diameter of the root growth tube 401 gradually decreases from top to bottom, so that the vortex gradually converges from top to bottom, and then flows into the cultivation frame 20 through the root growth tube 401, flows out through the gap between the cultivation frame 20 and the flowing liquid partition plate 203, and forms a closed structure with the sealing plate 202 and the cultivation frame 20. The gap outlet formed by the liquid outlet baffle 201, the cultivation frame 20 and the flowing liquid partition plate 203 allows the nutrient solution to flow from the sealing plate 202 to the direction of the liquid outlet baffle 201.

[0046] The nutrient solution then enters the separated liquid outlet pipe 50, flows to the lower side of the separated liquid outlet pipe 50 through the through holes of the mass-liquid separation net 502, and then flows into the circulation connecting pipe 304, flows through the circulation connecting pipe 304 to the liquid separation pipe 303 of the next layer, and flows again in the volute pipe 402 until it enters the separated liquid outlet pipe 50 at the lower side, flows through the discharge pipe 305 and returns to the nutrient solution tank 10, thus forming a circulation of the nutrient solution.

[0047] Embodiment 2:

[0048] When there are impurities in the vegetation cultivation tube 40 or the root growth tube 401, or necrotic rhizomes appear in the vegetation rhizomes, the impurities and necrotic rhizomes are brought into the gap between the cultivation frame 20 and the flowing liquid partition plate 203 through the vortex formed by the nutrient solution in the root growth tube 401, and then brought into the separated liquid outlet pipe 50 by the nutrient solution, and part of the nutrient solution is introduced into the circulation connecting pipe 304 through the through holes on the mass-liquid separation net 502. At the same time, the impurities and necrotic rhizomes are brought into the impurity interception chute 501 and blocked by the impurity interception net 5011, so that the impurities and necrotic rhizomes are stored together in the impurity interception chute 501, which is convenient for the operator to clean.

[0049] Since the nutrient solution preferentially flows downward through the circulation connection pipe 304, the amount of nutrient solution pumped into the upper liquid separation pipe 303 is intermittently increased by controlling the circulation water pump 30, so that when the nutrient solution flows through the mass-liquid separation net 502, the amount of nutrient solution flowing is greater than the amount flowing in the circulation connection pipe 304, so that the excess nutrient solution pushes the impurities and necrotic rhizomes on the mass-liquid separation net 502 to flow into the impurity interception slideway 501. It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
