Description

Technical Field

[0001] The utility model relates to the technical field of agriculture, in particular to a composite filter used in agricultural pools. Background Art

[0002] With the continuous advancement of agricultural technology, canvas water tanks will be built in open spaces. In order to ensure the safety of canvas water tanks, most of the canvas water tanks will be buried underground, and a small part will be exposed to the ground. As a new type of water-saving irrigation method, orchard canvas water tanks have the advantages of saving water resources, reducing costs, strong adaptability, and environmental sustainability. In the actual use of canvas water tanks, since the water in the canvas water tanks is only used to irrigate crops, there is no cover on the canvas water tanks. It is okay for daily use. When encountering strong winds, the leaves and dead branches of surrounding plants will be blown into the canvas water tanks, and there is no filtering device in the existing canvas water tanks. When the water in the canvas water tanks is pumped out by the water pump, the leaves and dead branches of the plants that fall into the canvas water tanks are likely to cause the water pumps to be blocked. Therefore, a composite filter for agricultural water tanks is needed to meet the needs. Utility Model Content

[0003] The utility model aims to solve the defect that no filtering device is arranged in the canvas water storage tank in the prior art, and proposes a composite filter for agricultural water pool.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A composite filter for an agricultural water pool is designed, comprising a circular ring, on which a plug-in cylinder is fixed, on which a first frame, a second frame and a third frame are fixed in sequence from top to bottom, on which a first filter net, a second filter net and a third filter net are fixed respectively, and the meshes of the first filter net, the second filter net and the third filter net are gradually reduced.

[0006] Preferably, the insertion cylinder is a truncated cone structure.

[0007] Preferably, a lifting mechanism is fixed on the circular ring.

[0008] Preferably, the lifting mechanism includes a fixed frame, on which a plurality of second threaded rods are equidistantly fixed, each of which is threadedly fitted with a connecting tube, each of which is threadedly inserted with a first threaded rod, and each of which is fixed on the circular ring.

[0009] Preferably, the fixing frame is a cross-shaped structure.

[0010] Preferably, an adjustment mechanism is fixed on the fixing frame.

[0011] Preferably, the adjustment mechanism comprises two linear motors, the two linear motors are symmetrically fixed on the fixing frame, and a support plate is fixed on both of the two linear motors.

[0012] Preferably, a bottom plate is fixed on each of the two support plates, and a plurality of pulleys is fixed on each of the bottom plates.

[0013] The utility model proposes a composite filter for agricultural water pools, which has the beneficial effect that when the composite filter for agricultural water pools is in use, the insertion tube is inserted into the specified position in the canvas water reservoir by means of a circular ring, and the leaves and dead branches of plants falling into the canvas water reservoir are blocked in layers with the assistance of the first filter screen, the second filter screen and the third filter screen, so as to prevent impurities from falling to the bottom of the canvas water reservoir, and thus the water pump in the canvas water reservoir will not be blocked by impurities, thereby ensuring the smooth use of the canvas water reservoir.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example 1: Reference Figure 1-5 A composite filter for an agricultural water pool includes a ring 2, on which a plug-in cartridge 1 is fixed, and the plug-in cartridge 1 is a truncated cone structure. When the truncated cone-shaped plug-in cartridge 1 is inserted into a canvas water reservoir, the plug-in cartridge 1 is inserted into a designated position in the canvas water reservoir due to the support of the ring 2, that is, the foundation of the ring 2 and the top of the canvas water reservoir, and there is a gap between the plug-in cartridge 1 and the canvas water reservoir, which will not damage the surface of the canvas water reservoir, and will not allow leaves and dead branches of surrounding plants to fall into the gap between the plug-in cartridge 1 and the canvas water reservoir;

[0022] A first frame 3, a second frame 4 and a third frame 5 are fixed on the insertion tube 1 from top to bottom in sequence, and a first filter screen 6, a second filter screen 7 and a third filter screen 8 are fixed on the first frame 3, the second frame 4 and the third frame 5 respectively. The meshes of the first filter screen 6, the second filter screen 7 and the third filter screen 8 are gradually reduced. The first filter screen 6, the second filter screen 7 and the third filter screen 8 can filter out impurities of different sizes from top to bottom in sequence to ensure that no impurities fall to the bottom of the canvas water reservoir.

[0023] When in use, the insertion tube 1 is inserted into the canvas water reservoir. When the ring 2 contacts the top of the canvas water reservoir, the insertion tube 1 is inserted into the designated position in the canvas water reservoir under the obstruction of the ring 2. The first frame 3, the second frame 4 and the third frame 5 respectively carry the first filter 6, the second filter 7 and the third filter 8 and are inserted into the canvas water reservoir together with the insertion tube 1. The leaves and dead branches of plants falling into the canvas water reservoir are blocked in layers with the assistance of the first filter 6, the second filter 7 and the third filter 8 to prevent impurities from falling to the bottom of the canvas water reservoir, so that the impurities will not clog the water pump in the canvas water reservoir, thereby ensuring the smooth use of the canvas water reservoir. In addition, when it is necessary to clean the impurities in the canvas water reservoir, the staff lifts the ring 2 and can remove the impurities left on the first filter 6, the second filter 7 and the third filter 8 from the canvas water reservoir at one time to ensure the cleanliness of the canvas water reservoir.

[0024] Embodiment 2: In embodiment 1, since the first frame 3, the second frame 4 and the third frame 5 are respectively carrying the first filter 6, the second filter 7 and the third filter 8 are all immersed in the water of the canvas reservoir, it takes a lot of effort to manually lift the ring 2. Figure 1-5As another preferred embodiment of the utility model, the difference from the embodiment 1 is that a lifting mechanism is fixed on the ring 2, and the lifting mechanism includes a fixing frame 12, and a plurality of second threaded rods 11 are fixed on the fixing frame 12 at equal intervals, and the plurality of second threaded rods 11 are all threadedly sleeved with connecting tubes 10, and the plurality of connecting tubes 10 are all threadedly inserted with first threaded rods 9, and the plurality of first threaded rods 9 are all fixed on the ring 2, and the plurality of second threaded rods 11 and the plurality of first threaded rods 9 are detachably mounted together by using the plurality of connecting tubes 10, so as to facilitate the disassembly and installation between the plurality of second threaded rods 11 and the plurality of first threaded rods 9;

[0025] The fixed frame 12 is a cross-shaped structure, and an adjustment mechanism is fixed on the fixed frame 12. The adjustment mechanism includes two linear motors 13. The two linear motors 13 are symmetrically fixed on the fixed frame 12. Support plates 14 are fixed on the two linear motors 13. The two linear motors 13 work synchronously. The two linear motors 13 are used to adjust the height of the ring 2 through the fixed frame 12, thereby changing the height of the first frame 3, the second frame 4, the third frame 5, the first filter screen 6, the second filter screen 7 and the third filter screen 8. Base plates 15 are fixed on the two support plates 14, and multiple pulleys 16 are fixed on each base plate 15.

[0026] When it is necessary to clean the impurities on the first filter screen 6, the second filter screen 7 and the third filter screen 8, start the two linear motors 13, and let the two linear motors 13 drive the ring 2 and the insertion tube 1 to rise through the fixed frame 12, instead of manual work, and more labor-saving and easy to take out the first frame 3, the second frame 4, the third frame 5, the first filter screen 6, the second filter screen 7 and the third filter screen 8 from the water in the canvas water reservoir, and when the height of the third filter screen 8 and the insertion tube 1 exceeds the top of the canvas water reservoir, the first filter screen 6, the second filter screen 7 and the third filter screen 8 can be moved to one side of the canvas water reservoir by using multiple pulleys 16. Therefore, when cleaning the impurities on the first filter screen 6, the second filter screen 7 and the third filter screen 8, no impurities will enter the canvas water reservoir again. After cleaning, when using it again, twist the multiple connecting tubes 10 to separate the multiple second threaded rods 11 and the multiple first threaded rods 9, and insert the insertion tube 1 into the canvas water reservoir again.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
