Description

Technical Field

[0001] This utility model relates to a water flow distributor, specifically a uniform water flow distributor for wheat field irrigation, and belongs to the technical field of water flow distributors. Background Technology

[0002] A water distributor is a device specifically designed to regulate and distribute water flow. Its core function is to distribute water from a single source to multiple irrigation branches or outlets according to a preset ratio or uniformity. It typically consists of an inlet, a distribution chamber, control valves, and multiple outlets. The application of water distributors is particularly crucial in wheat field irrigation. Wheat growth is sensitive to water availability; different plots have varying soil water retention capacities, terrain slopes, and crop growth stages. Traditional irrigation methods can easily lead to localized drought (water shortage affecting growth) or waterlogging (root suffocation and yield reduction) due to uneven water distribution. A water distributor, by evenly distributing water, ensures that each wheat field or each crop receives a stable and adequate amount of irrigation water, meeting the wheat's growth needs while avoiding resource waste.

[0003] In wheat field irrigation, drip irrigation and sprinkler irrigation technologies have become the mainstream choices for achieving efficient water conservation and precise water control. These two methods deliver water directly to the crop roots in the form of fine droplets or uniform atomization through low-pressure pipeline systems. This significantly reduces evaporation loss and avoids soil compaction and nutrient loss caused by traditional flood irrigation, thus creating a suitable water environment for wheat growth. However, existing water distributors have shortcomings in water source filtration. Impurities in the water can easily clog drip irrigation emitters or sprinkler heads after entering the branch pipes. This not only affects the uniformity of irrigation, leading to under- or over-irrigation in some wheat fields, but may also damage the drip irrigation emitters or sprinkler heads, increasing maintenance and replacement costs. Therefore, a uniform water distributor for wheat field irrigation is proposed. Utility Model Content

[0004] In view of this, the present invention provides a uniform water distribution device for wheat field irrigation to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0005] The technical solution of this utility model embodiment is implemented as follows: a uniform distributor of irrigation water for wheat fields, including a distribution pipe, wherein a filter component is provided inside the distribution pipe;

[0006] The filter assembly includes a retainer, three filter screens, a cap, a limiting seat, a limiting protrusion, a limiting track, and a limiting groove.

[0007] The limiting rails are symmetrically fixedly connected to the inner sidewall of the retainer. The filters are all inserted into the two corresponding upper and lower limiting rails. The front and rear parts of the outer wall of the retainer are provided with openings. Two sealing rings are symmetrically embedded in the outer wall of the retainer, and the sealing rings are located outside the opening of the retainer. The retainer is located inside the distribution tube and fits against the inner wall of the distribution tube through the sealing rings. The limiting seat is fixedly connected to one side of the inner wall of the distribution tube, and the limiting seat is symmetrically fixedly connected with limiting protrusions. The retainer has symmetrically opened limiting grooves on one side. One end of the distribution tube is threaded with a cap.

[0008] More preferably, the two sides of the retainer are attached to the opposite surfaces of the cover and the limiting seat by sealing gaskets, and the outer wall of the cover is provided with a buckle groove.

[0009] More preferably, the limiting protrusion is inserted into the inner wall of the limiting groove.

[0010] In a further preferred embodiment, a pull rod is fixedly connected to the side of the inner wall of the retainer away from the limiting protrusion.

[0011] More preferably, an inlet pipe is installed on the rear part of the outer wall of the distribution pipe, and an outlet pipe is installed at equal intervals on the front part of the outer wall of the distribution pipe.

[0012] More preferably, both the inlet pipe and the outlet pipe are connected to the distribution pipe, and both the inlet pipe and the outlet pipe are connected to the retainer.

[0013] More preferably, the pore size of the three filters decreases sequentially from back to front.

[0014] More preferably, a control valve is installed at the end of the water outlet pipe, and a connector is installed at the water outlet end of the control valve.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] In this invention, when transporting irrigation water, the water source first undergoes step-by-step filtration through three filters within the retainer. Then, the filtered water is evenly distributed to different branch pipes via the outlet pipe, and finally flows to various irrigation areas in the field, ensuring uniform irrigation. Compared to existing technologies, this invention achieves three-stage filtration of the water source by setting a filtration component inside the distribution pipe, ensuring the cleanliness of the water source and preventing clogging of drip irrigation or sprinkler heads, thus guaranteeing uniform irrigation. Moreover, the three-stage filtration greatly slows down the rate of filter clogging and reduces the frequency of cleaning. In addition, the retainer, filters, and caps are all designed to be detachable, allowing for quick removal of the filters and facilitating filter maintenance.

Detailed Implementation

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-4 As shown, this utility model embodiment provides a uniform distributor for irrigation water in wheat fields, including a distribution pipe 11, and a filter assembly 101 is provided inside the distribution pipe 11;

[0027] The filter assembly 101 includes a retainer 12, three filter screens 13, a cover 14, a limiting seat 15, a limiting protrusion 16, a limiting track 18, and a limiting groove 20;

[0028] The limiting rails 18 are symmetrically fixed to the inner wall of the retainer 12. The filter screens 13 are all inserted into the two corresponding upper and lower limiting rails 18. The inner side of the limiting rails 18 is provided with a sliding groove with a size that matches the filter screen 13. Therefore, with the cooperation of the upper and lower limiting rails 18, the filter screen 13 can be easily inserted and pulled out, realizing the quick installation and disassembly of the filter screen 13, which is convenient for cleaning or replacement.

[0029] The outer wall of the retainer 12 has openings at both the front and rear. Two sealing rings 17 are symmetrically fitted into the outer wall of the retainer 12, and the sealing rings 17 are located around the openings of the retainer 12. The retainer 12 is located inside the distribution pipe 11 and is in contact with the inner wall of the distribution pipe 11 through the sealing rings 17. The sealing rings 17 ensure that the water flow must pass through the filter screen 13 inside the retainer 12 and be filtered, and will not bypass the filtration system through the gap between the retainer 12 and the distribution pipe 11, thus ensuring the forced filtration.

[0030] The limiting seat 15 is fixedly connected to one side of the inner wall of the distribution pipe 11, and the limiting protrusion 16 is symmetrically fixedly connected to the limiting seat 15. The retainer 12 has a symmetrically opened limiting groove 20 on one side, and the limiting protrusion 16 is inserted into the inner side wall of the limiting groove 20. The limiting seat 15, the limiting protrusion 16 and the limiting groove 20 can play the role of positioning and preventing rotation, so as to ensure that the retainer 12 can be fixed in the correct position after being inserted into the distribution pipe 11, and will not rotate or move, thereby ensuring that the sealing ring 17 is aligned and sealed, and the inlet and outlet are connected to the inside of the retainer 12.

[0031] In one embodiment, one end of the distribution tube 11 is threadedly connected to a cap 14, and the two sides of the retainer 12 are attached to the opposite surfaces of the cap 14 and the limiting seat 15 by sealing gaskets. The cap 14 is used to seal the end of the distribution tube 11.

[0032] When the cover 14 is tightened, the cover 14 presses the retainer 12 inward, and with the cooperation of the limit seat 15, the position of the retainer 12 can be limited.

[0033] By rotating the cover 14 in the reverse direction, the cover 14 can be removed so that the retainer 12 can be taken out and the filter screen 13 can be replaced, thus facilitating maintenance;

[0034] The outer wall of the cover 14 is provided with a fastening groove 21, which facilitates the screwing of the cover 14.

[0035] In one embodiment, a pull rod 19 is fixedly connected to the side of the inner wall of the retainer 12 away from the limiting protrusion 16. After the cover 14 is removed, the retainer 12 can be easily removed by the pull rod 19.

[0036] In one embodiment, an inlet pipe 31 is installed on the rear part of the outer wall of the distribution pipe 11, and an outlet pipe 32 is installed at equal intervals on the front part of the outer wall of the distribution pipe 11. Both the inlet pipe 31 and the outlet pipe 32 are connected to the distribution pipe 11 and to the retainer 12. The water flow paths of the inlet pipe 31 and the outlet pipe 32 pass through the internal filter chamber of the retainer 12.

[0037] The inlet pipe 31 is used to connect to the main irrigation pipe and introduce unfiltered water into the distribution pipe 11;

[0038] The outlet pipe 32 is used to evenly distribute the filtered water into different branch pipes, and then flow to various irrigation areas in the field, thus realizing the function of even water distribution.

[0039] In one embodiment, the pore size of the three filter screens 13 decreases from back to front, thereby achieving three-stage filtration. When water flows through, it first passes through the filter screen 13 with larger pores to intercept large impurities such as leaves and insect remains. Then it passes through the filter screen 13 with medium pores, and finally the finest filter screen 13 intercepts tiny particles such as silt. This avoids all impurities accumulating on the finest filter screen 13, greatly slows down the clogging speed of the filter screen 13, and reduces the cleaning frequency.

[0040] After impurities are filtered out, the water flows into the branch pipes without clogging the drip irrigation emitters or sprinkler heads, thus ensuring the uniformity of irrigation.

[0041] In one embodiment, a control valve 33 is installed at the end of the outlet pipe 32, and a connector 34 is installed at the outlet end of the control valve 33. The connector 34 is used to connect to the branch pipes of the ground drip irrigation or sprinkler irrigation in the field. Any branch pipe can be opened or closed individually by controlling the valve 33, which facilitates zoned irrigation, maintenance or flow regulation.

[0042] When this utility model is in operation: water flows from the inlet pipe 31 into the distribution pipe 11, and first passes through the three filters 13 in the retainer 12 for step-by-step filtration. The three filters 13 intercept impurities of different particle sizes. Then the outlet pipe 32 evenly distributes the filtered water into different branch pipes, and finally flows to various irrigation areas in the field, ensuring the uniformity of irrigation.

[0043] When the filter screen 13 needs to be cleaned or replaced, the operator rotates and unscrews the cover 14 through the slot 21, and then pulls the retainer 12 out of the distribution tube 11 through the pull rod 19. At this time, the operator can clean or replace the filter screen 13 inserted inside the limit track 18 according to the actual situation.

[0044] After cleaning or replacement, put the retainer 12 back into the distribution tube 11 so that the limiting groove 20 aligns with the limiting protrusion 16, and then tighten the cap 14. The filter screen 13 is now maintained.

[0045] Compared with the prior art, this utility model can achieve three-stage filtration of water source by setting a filter component 101 inside the distribution pipe 11, which ensures the cleanliness of water source and prevents clogging of drip irrigation drippers or sprinkler heads, thus ensuring the uniformity of irrigation. Moreover, the three-stage filtration greatly slows down the clogging speed of filter screen 13 and reduces the cleaning frequency. At the same time, the retainer 12, filter screen 13, cover 14 and other structures are all designed to be detachable, which can quickly remove filter screen 13 and facilitate the maintenance of filter screen 13.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
