Abstract
Description
Technical Field
[0001] This utility model relates to the field of farmland ecological technology, specifically to an ecological interception ditch for farmland runoff with purification function. Background Technology
[0002] The location of ecological interception ditches for farmland drainage is determined based on the topography, water flow direction, and surrounding environment of the farmland. They are generally located downstream of the farmland or near the drainage outlet to maximize the interception of farmland drainage.
[0003] However, existing technologies still have many shortcomings in practical use. For example, soil, weeds, straw and other impurities carried by farmland runoff gradually accumulate in the interception ditch. It is inconvenient to turn over the soil and impurities in the interception ditch. These debris tend to accumulate at the bottom and walls of the ditch. Over time, they will gradually reduce the cross-sectional area of the interception ditch, resulting in poor water flow and even blockage. At the same time, impurities and floating objects may carry various pollutants, such as pesticide residues, fertilizers, and heavy metals. It is inconvenient to intercept impurities and floating objects from entering the interception ditch. If these substances directly enter the interception ditch, the concentration of pollutants in the water will increase, exceeding the purification capacity of the ecological interception ditch.
[0004] To address the aforementioned problems, the inventors proposed an ecological interception ditch for farmland runoff with purification functions. Utility Model Content
[0005] To address the problems of inconvenience in turning over the soil and impurities in the interception ditch and inconvenience in intercepting impurities and floating objects from entering the interception ditch, the purpose of this utility model is to provide an ecological interception ditch for farmland drainage with purification function.

[0007] As a preferred technical solution of this application, the snap-fit device includes a connecting plate, a handle is fixedly connected to the top surface of the connecting plate, a plurality of through slots are opened on the top surface of the fixed plate, a hollow sleeve is fixedly connected to the inner wall of the through slot, a spring is fixedly connected to one side inner wall of the hollow sleeve, a limit ball is fixedly connected to the end of the spring, a snap-fit rod is symmetrically fixedly connected to the bottom surface of the connecting plate, and a baffle is fixedly connected to the bottom surface of the connecting plate.
[0008] With the above technical solution, after the clamping rod is inserted into the through groove, when the spring pushes the limiting ball into the limiting hole, the connecting plate can be firmly fixed on the fixed plate, preventing the connecting plate from loosening or falling off during operation, ensuring that the baffle can stably play its role in intercepting impurities. When disassembly is required, the spring force is overcome, and the limiting ball is withdrawn from the limiting hole, so the clamping rod can be pulled out of the through groove, which facilitates the maintenance and replacement of components such as the baffle. Thus, it can effectively intercept impurities and floating objects and prevent them from entering the interception ditch with the water flow.
[0009] As a preferred technical solution of this application, the outer surface of the guide rod is movably connected to the sliding plate.
[0010] With the above technical solution, the fixing plate can slide along the guide rod in the groove.
[0011] As a preferred technical solution of this application, the lower part of the fixing plate is in contact with the inner wall of the slide groove.
[0012] With the above technical solution, the fixing plate slides within the groove.
[0013] As a preferred technical solution of this application, the outer surface of the lever is provided with a limiting hole for use with a limiting ball.
[0014] With the above technical solution, when the spring pushes the limiting ball into the limiting hole, the connecting plate can be firmly fixed on the fixing plate.
[0015] As a preferred technical solution of this application, the end of the lever extends into the through groove.
[0016] The above technical solution can firmly fix the connecting plate to the fixing plate.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model allows the fixed plate to slide along the guide rod in the chute, facilitating operation at different locations within the ecological interception ditch for farmland drainage, promoting the purification of farmland water quality, and thus achieving the purpose of turning over the soil and impurities within the interception ditch.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example: Figure 1-4 As shown, this utility model provides an ecological interception ditch for farmland drainage with purification function, including a ditch plate 1, a sliding device 2 provided in the fixed trough plate 1, the sliding device 2 including a fixed plate 21, a snap-fit device 3 symmetrically inserted on one side of the top surface of the fixed plate 21, a sliding plate 22 symmetrically fixedly connected to the lower part of the fixed plate 21, a sliding groove 23 symmetrically opened on the top surface of the ditch plate 1, the lower part of the fixed plate 21 is in contact with the inner wall of the sliding groove 23, a guide rod 24 is fixedly connected between the inner walls of the two sides of the sliding groove 23, the outer surface of the guide rod 24 is movably sleeved with the sliding plate 22, and a plurality of plow plates 25 distributed at equal intervals are fixedly connected to the lower inner wall of the fixed plate 21.
[0026] The guide rod 24 can limit the movement direction of the slide plate 22, ensuring that the fixed plate 21 slides on the ditch plate 1 along the predetermined path, which facilitates operation at different locations in the ecological interception ditch for farmland drainage, promotes the purification of farmland water quality, and can turn over the soil and impurities in the interception ditch.
[0027] The snap-fit device 3 includes a connecting plate 31, a handle 32 fixedly connected to the top surface of the connecting plate 31, a plurality of through slots 33 opened on the top surface of the fixing plate 21, a hollow sleeve 34 fixedly connected to the inner wall of the through slot 33, a spring 35 fixedly connected to one side inner wall of the hollow sleeve 34, a limit ball 36 fixedly connected to the end of the spring 35, a snap-fit rod 37 symmetrically fixedly connected to the bottom surface of the connecting plate 31, the end of the snap-fit rod 37 extending into the through slot 33, a limit hole 38 for use with the limit ball 36 opened on the outer surface of the snap-fit rod 37, and a baffle 39 fixedly connected to the bottom surface of the connecting plate 31.
[0028] When disassembly is required, the spring force of the spring 35 is overcome, and the limiting ball 36 is disengaged from the limiting hole 38. The locking rod 37 can then be pulled out from the through groove 33, making it convenient to maintain and replace components such as the baffle net 39. This allows for the interception of impurities and floating objects as needed, preventing them from entering the interception ditch with the water flow.
[0029] The working principle of an ecological interception ditch for farmland drainage with purification function according to an embodiment of this application is as follows: The ditch plate 1 serves as the basic structure, providing support for the entire ecological interception ditch. The sliding device 2 is installed inside the ditch plate 1. The sliding plate 22 at the bottom of the fixed plate 21 cooperates with the sliding groove 23 on the top surface of the ditch plate 1, so that the fixed plate 21 can slide along the guide rod 24 in the sliding groove 23. The guide rod 24 is fixed between the inner walls on both sides of the sliding groove 23, and its outer surface is movably connected with the sliding plate 22, playing a guiding and supporting role. The guide rod 24 can limit the movement direction of the sliding plate 22, ensuring that the fixed plate 21 slides on the ditch plate 1 along a predetermined path, which facilitates operation at different positions in the ecological interception ditch for farmland drainage, promotes the purification of farmland water quality, and thus achieves the purpose of turning over the soil and impurities in the interception ditch. When disassembly is required, pull the handle 32 upwards to separate the locking rod 37 from the fixing plate 21, facilitating the cleaning and maintenance of the baffle 39. After the locking rod 37 is inserted into the through groove 33, when the spring 35 pushes the limiting ball 36 into the limiting hole 38, it can firmly fix the connecting plate 31 onto the fixing plate 21, preventing the connecting plate 31 from loosening or falling off during operation, ensuring that the baffle 39 can stably play its role in intercepting impurities. When disassembly is required, overcome the elasticity of the spring 35 to allow the limiting ball 36 to exit from the limiting hole 38, and the locking rod 37 can be pulled out from the through groove 33, facilitating the maintenance and replacement of components such as the baffle 39. This achieves the purpose of intercepting impurities and floating objects as needed, preventing them from entering the interception ditch with the water flow.
[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
