Abstract

(57) [Summary] [Purpose] You can perform leveling work and compaction work, and reduce the turning radius. [Arrangement] An articulated vehicle body in which a rear frame 1 and a front frame 4 are connected by a vertical axis 5 and can be freely swung by a cylinder 6 to form an articulated vehicle body, and the rear and front frames 1 and 4 are used for rear and front rolling compaction. The rollers 3 and 8 are attached respectively, and a blade 10 provided with an auger 11 is provided at a lower portion of a front end of the rear frame 1 so as to be vertically movable by an elevator cylinder 12. As a result, the earth and sand can be excavated by the auger 11 and the blade 10 and discharged laterally, and can be compacted by the rear and front compaction rollers 3 and 8.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a civil engineering work vehicle for leveling and compacting roads, plazas, etc.

[0002]

[Prior Art]

 Motor graders are used for leveling roads and plazas, and compactors are used for compaction.

[0003]

[Problems to be solved by the device]

 A motor grader is required for leveling and a compactor is required for compaction, so two civil engineering work vehicles are required. Since the motor grader discharges the sand excavated with the blade slanted to the side, the wheel base is long so that the wheels do not interfere with the blade, and the turning radius is large, so it is not possible to perform leveling work on narrow roads and narrow open spaces.

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

[0005]

[Means for Solving the Problems]

 A rear frame equipped with a rear compaction roller and a front frame equipped with a front compaction roller are connected by a vertical axis and can be rocked left and right by a cylinder to form an articulated vehicle body. A civil engineering work vehicle in which a blade equipped with an auger at the intermediate position of the roller for partial pressure is mounted by a lifting cylinder so that it can be raised and lowered freely.

[0006]

[Work]

 The blade and auger can excavate the soil to level the soil, and the excavated soil can be discharged to the side, and can be compacted by the front and rear compaction rollers.

[0007]

【Example】

 As shown in FIG. 1, a rear rolling roller 3 is rotatably supported between a pair of left and right downward projecting pieces 2 and 2 of the rear frame 1, and a rear frame 1 is provided with a rear frame 4 at the front end thereof. The ends are swingably connected to each other on the vertical axis 5, and the cylinder 6 is connected to the rear frame 1 and the front frame 4 to form an articulated vehicle body. A front rolling roller 8 is rotatably supported between the downward projecting pieces 7 and 7, and a pair of left and right arms 9 is vertically swingably attached to a lower portion of a front end of the rear frame 1. A blade 10 and an auger 11 are attached between them, and the arm 9 is swung up and down by a lifting cylinder 12. In this auger 11, an auger screw is driven by a hydraulic motor, and either or both of the rear and front rolling rollers 3, 8 are rotationally driven by the hydraulic motor.

[0008]

[Effect of the device]

 The blade 10 and the auger 11 can be used for leveling work, and the front and rear rolling rollers 3, 8 can be used for rolling work. Since the earth and sand excavated by the auger 11 can be discharged to the side, it is not necessary to incline the blade 10, so that the wheel base can be shortened to reduce the turning radius, and even on narrow roads, leveling and compaction work can be performed. Since the soil is excavated and ground by the blade 10 and the auger 11, the traction force can be reduced as compared with the case where only the blade 10 is excavated, and sufficient excavation can be performed by the driving force of the front and rear roller compaction rollers 3, 8.
