Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention is to level roads and squares,
The invention relates to a compacted civil engineering work vehicle.

[0002]

2. Description of the Related Art A motor grader is used for leveling roads and open spaces, and a rolling machine is used for compaction.

[0003]

[Problem to be Solved by the Invention] A motor grader is required for leveling, and a rolling machine is required for compaction. Therefore, two civil engineering work vehicles are required. Since the motor grader discharges the earth and sand excavated with the blades slanting, the wheel base becomes long so that the wheels do not interfere with the blades, and the turning radius is large, so that the ground leveling work cannot be performed on a narrow road or a narrow square.

Therefore, an object of the present invention is to provide a civil engineering work vehicle capable of solving the above-mentioned problem.

[0005]

A rear frame 1 having a rear pressure roller 3 and a front frame 4 having a front pressure roller 8 are connected to each other so as to be able to swing right and left on a vertical axis 5, and a rear frame is provided. A cylinder 6 is connected between the front frame 4 and the front frame 4 to form an articulated vehicle body, and a blade 10 provided with an auger 11 at a position forward of the rear pressure roller 3 of the rear frame 1 is mounted on a lifting cylinder 12 Civil engineering work vehicle, which is mounted so that it can move up and down freely.

[0006]

[Operation] Since the ground leveling work can be performed by the blade 10 and the auger 11, and the rolling work can be performed by the front and rear rolling rollers 3 and 8, a versatile civil engineering work vehicle capable of performing the leveling work and the rolling work can be obtained. Since the earth and sand excavated by the auger 11 can be discharged to the side, the blade 10 does not have to be inclined, so that the wheel base can be shortened and the turning radius can be reduced, and the ground can be leveled and compacted even on a narrow road. Since soil is excavated and ground leveled by the blade 10 and the auger 11, the tractive force can be reduced as compared with the case of excavating only with the blade 10, and the driving force of the front and rear rollers 3 and 8 can be sufficiently excavated. Blade 1 with auger 11
Since 0 is attached to the rear frame 1, the angle of the blade 10 with respect to the rear frame 1 is always constant even when the vehicle turns right and left, so that excavation work can be easily performed.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a rear pressure roller 3 is rotatably supported between a pair of left and right downwardly projecting pieces 2, 2 of a rear frame 1, and a front end of the rear frame 1 is provided at a front end. The rear end of the frame 4 is connected to be able to swing left and right on a vertical axis 5, and a cylinder 6 is connected across the rear frame 1 and the front frame 4 to form an articulated vehicle body. A front pressure roller 8 is rotatably supported between a pair of left and right downwardly projecting pieces 7, 7, and a rear frame 1 is provided.
A pair of left and right arms 9 are attached to the lower part of the front end so as to be vertically swingable. A blade 10 and an auger 11 between the pair of right and left arms 9 are attached. In this auger 11, the auger screw is driven by a hydraulic motor, and both or one of the rear and front pressure rollers 3 and 8 is rotationally driven by a hydraulic motor.

[0008]

[Effect of the Invention] Since the ground leveling work can be performed by the blade 10 and the auger 11, and the rolling work can be performed by the front and rear rolling rollers 3 and 8, a versatile civil engineering work vehicle capable of performing the leveling work and the rolling work can be obtained. . Since the earth and sand excavated by the auger 11 can be discharged to the side, the blade 10 does not have to be inclined, so that the wheel base can be shortened and the turning radius can be reduced, and the ground can be leveled and compacted even on a narrow road. Since soil is excavated and ground leveled by the blade 10 and the auger 11, the tractive force can be reduced as compared with the case of excavating only with the blade 10, and the driving force of the front and rear rollers 3 and 8 can be sufficiently excavated. Since the blade 10 provided with the auger 11 is attached to the rear frame 1, the angle of the blade 10 with respect to the rear frame 1 is always constant even when turning left and right, so that the excavation work can be easily performed.
