Description

Technical Field

[0001] The present application relates to the field of soilless cultivation, and in particular to a filtering device for soilless cultivation of vegetables. Background Art

[0002] Soilless cultivation refers to a cultivation method that uses water, peat and other media as the substrate of the plant's roots to fix the plant so that the plant's roots can directly contact the nutrient solution. The composition of the nutrient solution in soilless cultivation is easy to control and can be adjusted at any time, so it has a wide range of applications. In the process of hydroponic vegetables, due to the lack of professional equipment, it is necessary to fertilize the vegetables manually, and the vegetables themselves will also release some waste and organic matter, which will make the water in the cultivation box polluted and turbid, so the water in the cultivation box needs to be replaced regularly;

[0003] In view of the above-mentioned related technologies, the inventor believes that common soilless cultivation devices have the defect that impurities in the water can easily block the water exchange port when the nutrient solution is replaced. It is often inconvenient to move the cultivation box during soilless cultivation, so the waste water will be replaced through the water exchange port. Therefore, a filtering device for soilless cultivation of vegetables is proposed to solve the above problem.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that impurities in the water easily block the water exchange port when replacing the nutrient solution in a common soilless cultivation device, the present application provides a filtering device for soilless cultivation of vegetables.

[0006] The present application provides a filtering device for soilless cultivation of vegetables using the following technical solution:

[0007] A filtering device for soilless cultivation of vegetables comprises a cultivation box and a cover plate, wherein the cover plate is arranged on the top of the cultivation box, a water exchange port is provided on the bottom wall of the cultivation box, a fixing groove is provided on the bottom wall of the cultivation box, the fixing groove is located outside the water exchange port, a filter ring is arranged in the fixing groove, a filter bag is arranged outside the filter ring, and two symmetrical fixing mechanisms are arranged on the bottom wall of the cultivation box.

[0008] Preferably, a hook is installed on the bottom wall of the cover plate, a ring is installed on the hook, a connecting rope is provided at the bottom of the ring, and the other end of the connecting rope is fixedly connected to the top wall of the filter bag.

[0009] Preferably, the bottom wall of the cultivation box is provided with two movement grooves, and the two movement grooves are respectively located on both sides of the fixed groove.

[0010] Preferably, the fixing mechanism includes a top rod, a vertical rod, a limiting plate and two magnetic plates, the vertical rod is installed in the motion groove, the top rod is installed on the top of the vertical rod, the limiting plate is installed on the bottom wall of the vertical rod, the cross-section of the limiting plate is "U"-shaped, the limiting plate is abutted against the top wall of the filter ring, and the two magnetic plates are respectively installed on the side walls at both ends of the limiting plate.

[0011] Preferably, a lever is installed on the top wall of the top rod, and the longitudinal section of the lever is arc-shaped.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] A filter bag is arranged outside the filter ring, and the filter ring is fixed to the outside of the water exchange port by two limiting plates. The two limiting plates will be tightly connected together under the action of the magnetic sheet, thereby ensuring the stability of the filter ring. Moreover, as the cover plate is lifted, the filter bag will be stretched, thereby increasing the filtration area, making the filter bag less likely to be blocked and improving the filtration efficiency.

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a filtering device for soilless cultivation of vegetables. Figure 1 and Figure 2 A filtering device for soilless cultivation of vegetables, comprising a cultivation box 1 and a cover plate 2, the cover plate 2 being arranged on the top of the cultivation box 1, a hook 7 being arranged on the bottom wall of the cover plate 2, a collar 8 being arranged on the hook 7, a connecting rope 9 being arranged at the bottom of the collar 8, the other end of the connecting rope 9 being fixedly connected to the top wall of a filter bag 6, when the filter bag 6 needs to be replaced, the collar 8, the connecting rope 9 and the filter bag 6 can be removed together, and when the cover plate 2 is lifted, the filter bag 6 will also be stretched, thereby increasing the area of ​​the filter screen;

[0020] The bottom wall of the cultivation box 1 is provided with a water exchange port 3. Under normal conditions, the water exchange port 3 will be blocked by a plug to ensure that the nutrient solution in the cultivation box 1 will not leak out;

[0021] A fixed groove 4 is provided on the bottom wall of the cultivation box 1, and the fixed groove 4 is located outside the water exchange port 3. A filter ring 5 is installed in the fixed groove 4, and a filter bag 6 is installed outside the filter ring 5. The opening of the filter bag 6 is fixed on the filter ring 5, so when the nutrient solution is replaced, it will be filtered by the filter bag 6.

[0022] Reference Figure 3 The bottom wall of the cultivation box 1 is provided with two movement grooves 10, which are respectively located on both sides of the fixed groove 4. The bottom wall of the cultivation box 1 is provided with two symmetrical fixing mechanisms, which include a top rod 11, a vertical rod 12, a limiting plate 13 and two magnetic sheets 14. The vertical rod 12 is arranged in the movement groove 10, the top rod 11 is arranged on the top of the vertical rod 12, and a lever 15 is arranged on the top wall of the top rod 11. The longitudinal section of the lever 15 is an arc-shaped design, and the arc-shaped lever 15 allows the staff to easily separate the two limiting plates 13;

[0023] The limiting plate 13 is installed on the bottom wall of the vertical rod 12. The cross-section of the limiting plate 13 is "U"-shaped. The limiting plate 13 is against the top wall of the filter ring 5. Two magnetic pieces 14 are respectively installed on the side walls at both ends of the limiting plate 13. The magnetic pieces 14 on the side walls of the two limiting plates 13 will attract each other, so that the filter ring 5 is firmly fixed in the current position.

[0024] The implementation principle of the filtering device for soilless cultivation of vegetables in the embodiment of the present application is as follows: when the nutrient solution in the cultivation box 1 needs to be replaced, the waste water in the cultivation box 1 needs to be poured out first, and the cover plate 2 is first lifted upward. Driven by the hook 7, the ring 8 will drive the connecting rope 9 and the filter bag 6 to rise together, so that the filter bag 6 is unfolded to increase the filtration area, and then the water change port 3 is opened, and the waste water in the cultivation box 1 will be filtered by the filter bag 6. When the filter bag 6 needs to be replaced, the two levers 15 can be pushed outward, so that the vertical rod 12 drives the limiting plate 13 to move outward, overcomes the magnetic force of the magnetic sheet 14 to do work, thereby loosening the restriction of the filter ring 5, and the staff can easily replace the filter bag 6.
