Description

Technical Field

[0001] The present application relates to the technical field of farmland drainage ditch support structures, and more specifically, to a farmland drainage ditch support structure. Background Art

[0002] The existing farmland drainage ditch support structure has a problem that the internal space of the ditch is mostly blocked by the support structure, resulting in reduced permeability of the drainage ditch and easy obstruction, reducing drainage efficiency and the convenience of personnel passing through for maintenance; therefore, it does not meet existing needs.

[0003] The document with the prior art publication number CN 220565160 U provides a farmland drainage ditch support structure. The device is provided with a ditch support guard plate, a limit adjustment block, a limit adjustment groove, a threaded hole, a convex connecting plate, a connecting plate fixing bolt, a double-headed threaded connecting rod, an extended connecting rod, a pushing adjustment block, a triangular bracket, a hydraulic cylinder, and a connecting beam. First, a group of ditch support guard plates are arranged on both sides of the inner wall of the drainage ditch. Then, the convex connecting plate is combined and connected with the limit adjustment groove at a corresponding height according to the height requirement of the on-site connecting beam. The convex connecting plate is fixed to the limit adjustment block using the connecting plate fixing bolt. Then, the double-headed threaded connecting rod is passed through the convex connecting plate and fixedly connected with the inner thread of the limit adjustment groove. Then, after the extended connecting rod is connected with the double-headed threaded connecting rod, the hydraulic cylinder output end of the hydraulic cylinder and the connecting beam combination is fixed to the pushing adjustment block. The connection between the bracket and the extended connecting rod and the push adjustment block greatly improves the force stability of the extended connecting rod. Due to the structural characteristics of the device, the space occupancy rate of the supporting structure between the trench support plates is greatly reduced, thereby greatly improving the pass rate of the internal space of the trench. In addition, since the hydraulic cylinder applies thrust to the push adjustment block, the extended connecting rod, and the double-headed threaded connecting rod, the structural stability and spacing adjustment ability of the trench support plates inside the trench are greatly improved. In addition, the extended connecting rod, the push adjustment block, the hydraulic cylinder, and the connecting beam combination can be installed upside down, thereby greatly meeting a variety of installation site conditions and solving the problem of existing farmland drainage ditch support structures, because the internal space of the trench is mostly blocked by the support structure, resulting in a decrease in the passability of the drainage ditch and being easily obstructed, reducing the drainage efficiency and the convenience of personnel passing through for maintenance.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the device requires the cooperation of a hydraulic cylinder, which increases the cost of use; and the support structure can only support the two sides of the drainage ditch, but cannot support the bottom of the drainage ditch, resulting in the erosion of the bottom soil of the ditch when water flows through.

[0005] In view of this, we propose a farmland drainage ditch support structure. Utility Model Content
