However, the prior grader additionally provided with the front bulldozer has the following problems in operation:

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

The embodiment provides a scraper transport machine which can carry out scraper transport, pushing transport or leveling of earthwork machines such as a machine bearing surface. Scraper transport machines can operate by traction and can be classified into bulldozers, scrapers, loader graders, earth movers, and the like, depending on their use. In this embodiment, the scraper transport machine is described by taking a grader as an example.

As shown in fig. 1, the grader 100 includes a machine body and a dozing mechanism 110. The bulldozer mechanism 110 may be disposed at the front side of the machine body, and is used to push the front stacked material to a designated position, thereby completing the backfilling operation.

As shown in fig. 2 and 3, the dozing mechanism 110 includes a dozer plate 1 and a mounting base 2. The blade 1 is mounted to the machine body by means of a mounting base 2. Optionally, the mounting base 2 may be fixed to the machine body by a fastener such as a bolt, which facilitates disassembly.

The blade 1 may be an arc-shaped blade. When the bull-dozer 1 contacts with the material of stacking, curved bull-dozer 1 can fully contact with the material, and area of contact is big, is favorable to reducing the operation resistance, and bull-dozer 1 promotes more smoothly, is favorable to improving the operating efficiency, reduces complete machine energy consumption and the wearing and tearing of bull-dozer 1.

For the intensity that improves bull dozer 1, the back of bull dozer 1, the one side that deviates from the material promptly can be provided with additional strengthening, for example the strengthening rib, is favorable to improving the bearing capacity of bull dozer 1, avoids bull dozer 1 atress to destroy.

In the prior art, the relative position of the bulldozer 1 and the bulldozer body is fixed, and when materials in a stacking state are operated, because the stacking states of the materials are different, the contact state of the bulldozer 1 with the materials in the operation state with the relative fixed position is not easy to control, so that the operation resistance is large, and the operation efficiency, the fuel consumption and the abrasion of the bulldozer 1 are directly influenced.

In order to take account of the trafficability of the entire grader 100, the design width of the bulldozer blade 1 is only slightly larger than the width of the grader body, and the working efficiency is relatively low under the working condition of bulldozer pushing lightly loaded materials or snow removing. When the material pile is large, the bulldozing plate 1 cannot complete bulldozing once, and the bulldozing operation needs to be performed for multiple times after the position of the complete machine is adjusted.

In order to solve the above problem, in the present embodiment, the blade 1 is capable of rotating around a vertical axis with respect to the mounting base 2 and is capable of sliding in a direction perpendicular to the dozing direction to adjust the inclination angle and position of the blade 1. For convenience of description, taking the front-rear-left-right direction when the driver operates the grader 100 as an example, the body is pushed forward when dozing, and the sliding direction of the blade 1 is the left-right direction.

The bulldozing plate 1 rotates around a vertical axis, so that the left-right inclination angle of the bulldozing plate 1 can be adjusted, and the contact angle between the bulldozing plate 1 and materials can be adjusted, thereby improving the operation resistance in the bulldozing process, improving the operation efficiency, and reducing the fuel consumption and the wear of the bulldozing plate 1; the material can be pushed to the two sides of the machine body, so that the position in front of the machine body is vacated, and snow removal or ice removal is facilitated. The material rolls to both sides, can also reduce the operating resistance.

The blade 1 can rotate around the vertical axis, and the size of the blade 1 in the left-right direction can be increased during design, so that the size of the blade 1 in the left-right direction is far larger than that of the body in the left-right direction. When the grader 100 needs to switch, the blade 1 can be tilted left and right, so that the size of the blade in the left and right direction is reduced, and the blade 1 is adjusted within the range of the left and right direction of the machine body, so as to be compatible with the trafficability of the grader 100.

The blade 1 slides in the left-right direction, and the blade 1 can be moved out of the machine body in the left-right direction. During operation, materials are positioned right in front of the bulldozer 1, and when the bulldozer pushes forwards, the bulldozer cannot pass through the area where the materials are positioned. For example, when snow removal or ice removal is carried out, the front wheel of the machine body can be prevented from contacting with snow or ice, the adhesive force of the front wheel is ensured, the front wheel is prevented from drifting, and the stability of the whole machine is improved.

After the bulldozer blade 1 is moved out of the grader body in the left-right direction, the bulldozer blade can be matched with a blade of the grader 100 to work, so that the working width of the whole grader 100 in the left-right direction is greatly increased, the reciprocating working frequency of the grader 100 is further reduced, and the improvement of the working efficiency is facilitated.

Specifically, the dozing mechanism 110 further includes an adjustment assembly 3, and the adjustment assembly 3 is used for driving the dozing plate 1 to move relative to the mounting base 2. Because there are a plurality of movements between bull dozer 1 and the mounting base 2, in order to avoid mutual interference between a plurality of movements, bull dozer mechanism 110 still includes first support 4, and first support 4 sets up between bull dozer 1 and mounting base 2, and the one end of first support 4 and bull dozer 1 are along horizontal direction sliding connection, and the other end and the mounting base 2 of first support 4 are connected around vertical axis rotation. Through setting up first support 4, can divide into the slip of first support 4 and bull dozer 1 and the rotation of first support 4 and mounting base 2 with two movements of bull dozer 1 and mounting base 2, it is independent with the rotation to slide, avoids the two mutual interference.
