Description

Technical Field

[0001] The utility model relates to the technical field of drainage ditch construction, in particular to a road drainage ditch excavation device. Background Art

[0002] At present, in various road construction projects, in order to drain rainfall, sewage, etc., it is generally necessary to dig drainage ditches on both sides of the embankment to guide rainfall and sewage to designated areas to avoid them from destroying roads or even causing natural disasters such as mudslides. Nowadays, in the excavation of drainage ditches, special grooving molds are often used according to the grooving type to cooperate with the mechanical power end for excavation. Compared with the traditional excavation of grooves, the grooves formed by one excavation are more in line with the expected shape, but the soil inside the groove after excavation is relatively loose, which is prone to falling and collapse. At the same time, part of the excavated soil will accumulate at the top edge to form a bulge, resulting in uneven ground, affecting the subsequent concrete filling operation. Utility Model Content

[0003] The purpose of the utility model is to provide a road drainage ditch excavation device, which can carry out more detailed repairs on the excavated ditch and compact and shape the inner soil of the ditch and the top edge soil to prevent it from loosening and collapsing, ensure the stability of the ditch, and facilitate subsequent concrete filling.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a road drainage ditch excavation device, including a pad, a fixing seat is embedded in the center of the pad, an assembly frame is symmetrically fixedly connected to the top of the fixing seat, and the left and right sides of the assembly frame are matched with assembly holes, a vertical plate is fixedly connected to the bottom center of the fixing seat, a trapezoidal trimming frame is fixedly connected to the bottom of the vertical plate, the top of the trapezoidal trimming frame is fixedly connected to the pad, and a plurality of leveling rollers are symmetrically arranged on the left and right sides of the fixing seat. The ground rollers are equidistantly distributed in the front and rear directions and are all engaged and rotatably connected with the pads. Side rollers are symmetrically arranged on the left and right rear parts of the trapezoidal finishing frame, and the side rollers are engaged and rotatably connected with the trapezoidal finishing frame. The bottom rear side of the trapezoidal finishing frame is engaged and rotatably connected with a pit leveling roller. By setting the trapezoidal finishing frame, the excavated trench can be repaired more finely and the ground rollers, side rollers and pit leveling rollers can be used to compact and shape the inner soil of the trench and the soil on the top edge of the trench to avoid loosening and collapse, thereby ensuring the stability of the trench and facilitating the subsequent filling of concrete.

[0005] According to the road drainage ditch excavation device, the outer sides of the leveling roller, the side roller and the pit leveling roller are all sleeved and fixed with rubber rings to squeeze and compact the soil inside the ditch to avoid excessive wear of the roller body caused by hard pressure.

[0006] According to the road drainage ditch excavation device, a plurality of positioning holes are provided through the center of the assembly frame in the front and rear directions, and the positioning holes are evenly distributed on the left and right sides and are equipped with positioning pins and fixed with the mechanical power end to maintain the stability of its moving direction.

[0007] According to the road drainage ditch excavation device, a layer of sliding film is provided on the bottom surface of the pad, and the bottom front edge of the pad is rounded, so that the pad can slide smoothly with the ground and reduce friction loss.

[0008] According to the road drainage ditch excavation device, the limiting plates are symmetrically fixed in the middle of the left and right sides of the vertical plate, and the opposite sides of the limiting plates are arranged to be tilted downward and extend into the inner wall of the trapezoidal trimming frame and are fixedly connected thereto, thereby improving the stability of the trapezoidal trimming frame.

[0009] According to the road drainage ditch excavation device, the front edges of the trapezoidal trimming frame and the vertical plate are both cut corners, so as to make it easier to cut out the soil.

[0010] The above scheme has the following beneficial effects:

[0011] In the utility model, a ladder-shaped finishing frame is provided to carry out more detailed repair of the excavated trench, and the ground-leveling roller, the side roller and the pit-leveling roller are used together to compact and shape the inner soil of the trench and the soil at the top edge of the trench to prevent loosening and collapse, thereby ensuring the stability of the trench and facilitating subsequent concrete filling.

[0012] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
