Abstract

The utility model relates to a hard road surface flatly cutting device for repairing roads. The hard road surface flatly cutting device is characterized in that the utility model comprises a working flatplate, shaving cutters and a push-pull rod; more than two shaving cutters are uniformly distributed on the lower planes of the working flatplate; the push-pull rod is arranged on the upper plane of the working flatplate. The hard road surface flatly cutting device can shave the convex parts of hard road surfaces flatly without damaging smooth road surfaces. Vehicles can run on a shaved cement road surface by removing broken disintegrating slag; traffic can be restored on a shaved asphalt road surface after the disintegrating slag is removed, asphalt is sprayed complementally, and small amount of fine stones are spread complementally. The utility model has the advantages of simple structure and low cost.

Description

Grader for hard pavement

The utility model relates to a kind of machinery that keeps in repair road, exactly is grader for hard pavement.

The existing highway road surface phenomenons such as pit, projection, wave can occur because of being subjected to the restriction of conditions such as construction precision, quality, equipment after accomplishing soon, travels on such road surface, and vehicle jolts, passenger's carsickness.No matter be asphalt surface, or cement pavement, when repairing road surface, this hard road, at first must be to pit, projection, that backing-off cutting is carried out on the wave road surface is smooth, this work at present, or by manpower pick, the operation of spade excavation, or by earth mover tool operation construction.

The purpose of this utility model is: provide a kind of in order to smooth hard pavement and can with matching used grader for hard pavement such as tractor, bulldozer.

The technical solution that realizes above-mentioned purpose is such:

Grader for hard pavement is characterized in that: this device comprises working plate, slicing cutter and pull bar; Plural slicing cutter is distributed on the lower plane of working plate, and pull bar is located at the last plane of working plate by bearing.

Described slicing cutter is made up of tool rest, cutter head and fixed bar, and tool rest is located at the working plate bottom surface, and cutter head is located on the tool rest by fixed bar.

The utility model is simple in structure, low cost of manufacture; Because there is numerous slicing cutter heads its working position, in the use, the bossing of hard surface can be planished, and not injure the smooth-riding surface.After the cement pavement planing, remove disintegrating slag and can pass through, after the asphalt surface planing, behind the removing disintegrating slag, the pitch that fills spray, benefit is spread a small amount of microlith and can be recovered to be open to traffic.

Description of drawings

Fig. 1 is the utility model structural front view,

Fig. 2 is the utility model structure vertical view,

Fig. 3 is the partial enlarged drawing of Fig. 1,

Fig. 4 is the lateral view of Fig. 3.

The utility model is further described by embodiment below in conjunction with accompanying drawing.

By Fig. 1, Fig. 2 as seen, this grader for hard pavement is made up of working plate 1, slicing cutter 2 and pull bar 3.Slicing cutter 2 more than ten is uniform to be installed on the lower plane of working plate 1; Slicing cutter 2 is made up of tool rest, carbide bit 6 and fixed bar, and tool rest is fixedly mounted on the bottom surface of working plate 1, and fixed bar is fixedly mounted on carbide bit 6 on the tool rest.And cutter head 6 can be relatively and working plate 1 bottom surface, along the direction swing of pull bar 3, pendulum angle is 7 degree, sees Fig. 3.Pull bar 3 is a V-type, and is fixedly installed in the last plane of working plate 1 by two bearings 4, bolt 5 and push rod shaft 7.

In the use, pull bar and power set are articulated, under power set drive, can carry out operation.This device both can be carried out operation, also can draw capable operation.
