Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural irrigation, in particular to an agricultural drainage irrigation anti-blocking device. Background Art

[0002] Agricultural irrigation mainly refers to irrigation operations in agricultural farming areas. Rural production is an important support for my country's rural economic and social development. Since the 1970s, my country's cultivated land area has continued to decrease, but the irrigation area has generally increased steadily, and most of the irrigation is done by diverting river water to irrigate farmland.

[0003] River water diversion is achieved by using a pumping pipe to transport river water from a lower height to the ground at a higher height. However, during operation, since the river water is mixed with impurities such as leaves and plastics, they can easily follow the water flow into the pumping pipe under the suction of the water pump. Therefore, a filter is usually installed at one end of the pumping pipe to filter out debris in the water. However, the blocked debris will be adsorbed on the surface of the filter and clog the filter, which will lead to a decrease in the flow rate of water entering the pumping pipe and affect the irrigation efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an agricultural drainage irrigation anti-blocking device, and the technical solutions adopted are as follows:

[0005] An agricultural drainage and irrigation anti-blocking device comprises a water suction head, one end of which is provided with a connecting pipe, the water suction head being composed of two arc-shaped covers, which are connected by a connecting plate;

[0006] A number of filter holes are provided on the surface of the water suction head, and a circular opening is provided in the water suction head toward one end of the connecting pipe; a rotating plate is installed inside the water suction head, one end of the rotating plate is connected to the fixed plate outside the water suction head by a connecting bolt, and the other end of the rotating plate is connected to the connecting rod in the connecting pipe by a connecting bolt, and a rotating vane is installed at one end of the connecting rod.

[0007] Furthermore, the outer edge of the connecting disk extends and protrudes toward one side, forming an L-shaped structure with the overall cross-section of the connecting disk.

[0008] Furthermore, the connecting rod passes through a circular opening in the water suction head, and both ends of the connecting rod are respectively connected to the rotating plate and the rotating blade to play a transmission role.

[0009] Furthermore, a mounting frame for supporting the connecting rod is provided in the connecting pipe, and a bearing is provided at the connection between the connecting rod and the mounting frame.

[0010] Furthermore, a corner of the upper surface of the rotating plate is set as an inclined chamfer, which can scrape the water flow toward the inner wall of the water suction head when the rotating plate rotates.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The utility model can utilize the water flow entering the connecting pipe to drive the rotary blade to rotate, and the rotating plate can rotate along with the rotary blade. The chamfered setting on one side of the rotating plate can drive part of the water flow to impact the inner surface of the water suction head. When the rotating plate rotates through the filter holes opened on the surface of the water suction head, the impact of the water flow can clean up the debris blocked outside the filter holes, ensuring that the river water can stably and continuously pass through the filter holes in the water suction head, preventing the water suction head from being blocked and reducing the irrigation efficiency.

[0022] In order to help those skilled in the art better understand the present invention, the following will 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 those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0023] As attached Figure 1-7 shown.

[0024] An agricultural drainage and irrigation anti-blocking device includes a water suction head 1, a connecting pipe 2 is provided at one end of the water suction head 1, and a water pipe is connected to one end of the connecting pipe 2 through a clamp; the water suction head 1 is composed of two arc-shaped covers, and the two covers are connected by a connecting plate 11, as shown in the attached figure. Figure 2 As shown, the outer edge of the connecting plate 11 extends and protrudes toward one side. Based on this structure, when the water suction head 1 is placed in the river channel, the connecting plate 11 can play a role in supporting and protecting the water suction head 1, preventing the filter holes opened inside the water suction head 1 from contacting with the silt in the river channel and causing the filter holes to be blocked. At the same time, it can also prevent the water suction head 1 from colliding with objects in the river channel and deforming when the water suction head 1 is below. At the same time, when the rotating plate 3 or the rotary vane 4 in the device fails, the water suction head 1 can be directly opened to facilitate the maintenance of the device.

[0025] A plurality of filter holes are provided on the surface of the water suction head 1, and a circular opening is provided in the water suction head 1 at one end facing the connecting pipe 2; a rotating plate 3 is installed inside the water suction head 1, and one end of the rotating plate 3 is connected to the fixing plate 5 placed outside the water suction head 1 through a connecting bolt 32, and a connecting rod 31 is connected to the other end of the rotating plate 3 through a connecting bolt 32, and one end of the connecting rod 31 passes through the circular opening provided in the water suction head 1, and a mounting bracket for supporting the connecting rod 31 is provided in the connecting pipe 2 21. A rotary vane 4 is installed at one end of the connecting rod 31 that passes through the water suction head 1, and a bearing 22 is provided at the connection between the connecting rod 31 and the mounting frame 21. According to the arrangement of the above structure, the connecting pipe 2 is connected to an external water pump through a water pipe. When the water pump is turned on, the river water enters the water suction head 1 through the filter holes. The river water entering the water suction head 1 flows into the connecting pipe 2 through the multiple filter holes and circular openings enclosed in the connecting pipe 2, and is finally transported to the water inlet of the water pump through the water pipe, and is transported by the water pump to the area to be irrigated.

[0026] When the river water flows into the connecting pipe 2, it will push the vanes 4 to rotate, and the rotating vanes 4 can drive the rotating plate 3 to rotate inside the water suction head 1 through the connecting rod 31. Figure 3 、 5 As shown, one corner of the upper surface of the rotating plate 3 is set as an inclined chamfer, as shown in the attached Figure 4 As shown, when the rotating plate 3 rotates counterclockwise following the rotating blade 4, the chamfered setting can push part of the water flow to impact the inner surface of the water suction head 1. When the rotating plate 3 rotates through the filter holes opened on the surface of the water suction head 1, the impact of the water flow can clean up the debris blocked outside the filter holes, ensuring that the river water can stably and continuously pass through the filter holes in the water suction head 1, preventing the water suction head 1 from being blocked and reducing the irrigation efficiency.

[0027] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
