[0002] The side ditch is the hub connecting the roadbed slope and the outer part of the road. The existence of the side ditch makes the connection between the roadbed and the roadside more perfect, and the beautiful side ditch can also greatly increase the landscape effect of the highway, playing the role of enriching the terrain. The existing side ditches are mostly trapezoidal structures, used to collect the surface water of the highway, drain the slope water intercepted by the roadbed above the road, quickly gather and introduce them into a smooth drainage channel, and discharge them below the road through culverts and bridges.
[0003] At present, the excavation of shallow dish-shaped side ditches mainly uses a backhoe excavator in cooperation with manual renovation construction, which has many deficiencies, including a large amount of over-excavated earthwork, and the need to repeatedly trim the excavation section and line; the use efficiency of the machine is low, and the excavation accuracy is not high. During on-site construction, manual filling of earthwork is also required, increasing the labor cost. The section after manual filling cannot fit accurately with the installation of precast blocks, resulting in a poor line for side ditch construction. At the same time, the rabbets between precast blocks cannot fit tightly, which also increases the quality risk of the side ditch being vulnerable to water damage in the later stage. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a mechanized grooving device for shallow dish-shaped side ditches with high efficiency, low cost and good grooving forming degree.

[0006] The length dimension of the grooving top plate is greater than the outer shape dimension of the grooving arc-shaped knife plate.
[0007] A mounting hole is processed on the grooving top plate, and the mounting hole is a blind hole; a lifting ring is installed in the mounting hole.
[0008] The first vertical plate and the second vertical plate are symmetrically arranged at a position close to the middle on the trench-opening arc-shaped knife plate and the grooving top plate.
[0009] Reinforcing rib plates are perpendicularly welded between the upper parts of the first vertical plate and the second vertical plate and the grooving top plate.
[0010] The cutter claw is provided with a straight surface part and an inclined surface part; an assembly clamping table is arranged between the straight surface part and the inclined surface part, and the assembly clamping table is clamped at the end face position of the trench-opening arc-shaped knife plate; fixing holes are machined on the straight surface part.
[0011] A sealing baffle is arranged on one side of the trench-opening arc-shaped knife plate away from the cutter claw.
[0012] The fixed seat sleeves are respectively connected to the lifting power frame and the flipping power frame through connecting shafts.

[0017] 2. The size specifications of the trench-opening arc-shaped knife plate in the utility model correspond to those of the bucket cavity, and the bucket cavity can effectively shovel out the soil generated during the trench-opening process.
[0018] 3. The length dimension of the grooving top plate in the utility model is larger than the outer shape dimension of the trench-opening arc-shaped knife plate, so that the parts of the grooving top plate extending beyond the trench-opening arc-shaped knife plate at both ends can level the plane on both sides of the trench edge, and the trench-opening forming degree is good.
[0019] 4. After adopting the device of the utility model, the mechanical use efficiency can be effectively improved, the side ditch excavation process can be reduced, the cost can be reduced, the construction safety and construction quality at the construction site can be guaranteed, and the construction progress can be effectively accelerated at the same time.

[0027] A bucket cavity 4 is formed between the ditch-opening arc-shaped knife plate 1 and the grooving top plate 2; several cutter claws 3 extending outward are evenly distributed at the arc edge position of the ditch-opening arc-shaped knife plate 1; a part of the first vertical plate 5 and the second vertical plate 6 that is higher than the grooving top plate 2 forms an installation chamber 10; two groups of fixed seat sleeves 9 are symmetrically arranged on the first vertical plate 5 and the second vertical plate 6 outside the installation chamber 10, one group of fixed seat sleeves 9 is connected to the lifting power frame 11 of the excavator, and the other group of fixed seat sleeves 9 is connected to the flipping power frame 12 of the excavator; a flipping telescopic rod 13 is arranged at the middle position of the upper end of the flipping power frame 12, and the flipping telescopic rod 13 is connected to the hydraulic system.
[0028] Among them: the length dimension of the grooving top plate 2 is greater than the outer dimension of the ditch-opening arc-shaped knife plate 1. The grooving top plate 2 extending outward at both ends can level the plane on both sides of the ditch edge.
[0029] Mounting holes 7 are processed on the grooving top plate 2, and the mounting holes 7 are blind holes; lifting rings 16 are installed in the mounting holes 7. The setting of the lifting rings 16 facilitates the hoisting of the grooving structure.
[0030] The first vertical plate 5 and the second vertical plate 6 are symmetrically arranged at a position close to the middle on the ditch-opening arc-shaped knife plate 1 and the grooving top plate 2.
[0031] Reinforcing rib plates 8 are perpendicularly welded between the upper part of the first vertical plate 5 and the upper part of the second vertical plate 6 and the grooved top plate 2 respectively, which is used to enhance the overall strength of the structure.
[0032] The cutter claw 3 is provided with a straight surface part and an inclined surface part; an assembly clamping table 19 is arranged between the straight surface part and the inclined surface part, and the assembly clamping table 19 is clamped at the end face position of the ditch-opening arc-shaped cutter plate 1; fixing holes 20 are machined on the straight surface part. The cutter claw 3 and the ditch-opening arc-shaped cutter plate 1 are fixed by bolts or welding. The inclined surface part at the front end of the cutter claw 3 can improve the sharpness of the cutter claw 3.
[0033] A sealing baffle is arranged on one side of the ditch-opening arc-shaped cutter plate 1 away from the cutter claw 3, so that the bucket cavity 4 is a single-side open structure, which is used to hold the soil dug out during the grooving process and is convenient for sending out the soil.
[0034] The fixed seat sleeve 9 is respectively connected with the lifting power frame 11 and the flipping power frame 12 through connecting shafts. The flipping power frame 12 can drive the grooving device to rotate along the connecting shaft at the lower end of the lifting power frame 11.

[0037] Working principle:
[0038] During the construction of shallow saucer-shaped side ditch excavation, the lifting power frame 11 and the flipping power frame 12 of the excavator are respectively connected with a group of fixed seat sleeves 9 through connecting shafts. The grooving mechanism is driven by the lifting power frame 11 to move to the construction position. During the process of the lifting power frame 11 driving the ditch-opening arc-shaped cutter plate 1 to move, the ditch-digging operation is realized.
[0039] The cutter claws 3 are distributed on the outer side of the end face of the ditch-opening arc-shaped cutter plate 1, and the front end of the cutter claw 3 is provided with an inclined surface structure, which makes the grooving process more labor-saving. When the ditch-opening arc-shaped cutter plate 1 moves a certain distance, the soil generated by grooving enters the bucket cavity 4. The flipping power frame 12 drives the ditch-opening arc-shaped cutter plate 1 to rotate along the connecting shaft at the lower end of the lifting power frame 11, so that the cutter claws 3 are tilted upward, which can avoid the soil in the bucket cavity 4 from spilling out.
[0040] By driving the excavator to rise through the lifting power frame 11, and driving the ditch-opening arc-shaped cutter plate 1 to rotate along the connecting shaft at the lower end of the lifting power frame 11 through the flipping power frame 12, the cutter claws 3 are tilted downward, and the processed soil is dumped to the outer area or the transport vehicle.
