Problems solved by technology

However, this method needs to set up a support frame on the working surface in advance. The support frame must be kept accurate and level, and the operation is cumbersome. As the working area of ​​the bulldozer changes, the support frame needs to be moved frequently, which is very cumbersome.

Embodiment approach 1

[0034] Implementation mode one: if figure 1 , 2 As shown, the bulldozer with the laser leveling device comprises a car body 1 and a bulldozer 2, the bulldozer 2 is hinged at the front of the car body 1, and is equipped with a lifting cylinder 3, and a cab is arranged on the top of the car body 1. A steering wheel 4, an instrument panel 15 and a front windshield 16 are arranged in the room, and it is characterized in that: a fan-shaped laser emitter 5 is fixed on one side of the front of the car body 1, and the fan-shaped laser emitter 5 faces the ground in front of the car body 1. The longitudinal laser surface emits, and the angle between the longitudinal laser surface and any horizontal plane is an acute angle, and the intersection line of the longitudinal laser surface and the horizontal plane points to the front of the vehicle body, and the longitudinal laser surface forms a line on the ground in front of the vehicle body that can be used in the cab. The driver sees the l...

Embodiment approach 2

[0036] Implementation mode two: if image 3 As shown, the fan-shaped laser emitter 5 emits two longitudinal laser surfaces, and the two longitudinal laser surfaces intersect with the horizontal plane to form two intersection lines, the two intersection lines are parallel to each other, and the two longitudinal laser surfaces are at the front of the car body 1. A longitudinal laser indicator line 6 that can be seen by the driver in the cab is respectively formed on the ground.

Embodiment approach 3

[0037] Implementation mode three: if Figure 4As shown, there are two fan-shaped laser emitters 5, both of which are located on one side of the car body. Intersecting with the horizontal plane forms two intersection lines, the two intersection lines are parallel to each other, and the two longitudinal laser planes respectively form a longitudinal laser indicator line 6 on the ground in front of the vehicle body 1 that can be seen by the driver in the cab.

Abstract

The invention relates to a bulldozer with a laser leveling device and a corresponding ground leveling method. The existing ground leveling operation is complicated. Therefore the bulldozer with the laser leveling device comprises a vehicle body and a bulldozing blade, the bulldozing blade is hinged to the front part of the vehicle body, and is provided with a lifting oil cylinder, a cab is arranged above the vehicle body, and a steering wheel, an instrument panel and a front windshield are arranged in the cab. The bulldozer is characterized in that a fan-shaped surface laser emitter is fixedly arranged at one side of the front part of the vehicle body, the fan-shaped surface laser emitter sends out a longitudinal laser surface to the ground in front of the vehicle body, the included angle between the longitudinal laser surface and any one horizontal plane is an acute angle, in addition, the crossing line of the longitudinal laser surface and the horizontal plane points to the right front side of the vehicle body, and a longitudinal laser indicating line capable of being seen by a driver in the cab is formed by the longitudinal laser surface in the ground in front of the vehicle body. The invention also relates to the corresponding ground leveling method. The bulldozer and the corresponding ground leveling method have the advantages that the design is scientific, and the use is convenient. The bulldozer and the corresponding ground leveling method are widely applicable to various kinds of traffic, water conservancy and building construction.

Description

technical field [0001] The invention relates to a bulldozer with a laser leveling device and a corresponding ground leveling method. Background technique [0002] All need to carry out ground leveling operation in reservoir, embankment, bridge, aqueduct and road construction process, and prior art all is to adopt bulldozer or loader to carry out bulldozing, leveling operation. It is difficult for the driver to see the ups and downs of the ground ahead in the cab of the bulldozer or loader, and it is difficult to level the ground accurately. [0003] The Chinese invention patent application published on April 17, 2013 with publication number CN103046592A discloses a hybrid bulldozer and its leveling system and leveling method. In this method, a support frame needs to be arranged in front of the bulldozer, a laser emitter is arranged on the support frame, and a laser receiver is fixed on the body of the bulldozer so as to guide the driver to carry out bulldozer leveling opera...
