Description

Technical Field

[0001] The utility model belongs to the technical field of excavators, in particular to an excavator bulldozer which is easy to install. Background Art

[0002] With the rapid development of social economy, bulldozers are commonly used devices for engineering machinery to push earth and stone. Micro excavators are often used as a standard configuration. The maximum width of the bulldozer is generally the same as the chassis width of the entire machine. Under certain working conditions, the bulldozer of the excavator can play a role in removing obstacles in front, clearing the road surface or fixing the fuselage.

[0003] Many types of existing excavators are not suitable for bulldozers and require special parts to install the bulldozers. In addition, the bulldozers need to be aligned with the installation position during the installation process. During the alignment, the bulldozers will be affected by the gravity of the bulldozers, causing them to fall or tilt. This process requires multiple workers, which not only wastes human resources but also wastes time. Therefore, we have proposed an excavator bulldozer that is easy to install. Utility Model Content

[0004] The purpose of the present invention is to provide an excavator bulldozer that is easy to install. By setting a fixing component, specifically, when installing the bulldozer, the two L-fixing rods on the front and rear sides can be hung on the excavator mounting seat first. After the L-fixing rod one contacts the excavator mounting seat, two fixing rods are inserted through the square holes on the upper ends of the L-fixing rod two. At the same time, after the fixing rods are inserted, the L-fixing rod two can be prevented from being offset by gravity, which makes installation more convenient for the installer. This solves the problem that the existing installation process requires the bulldozer to be aligned with the installation position. Since the bulldozer is affected by the gravity of the bulldozer during alignment, it may fall or tilt, resulting in the need for multiple workers in this process, which not only wastes human resources but also wastes time.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is an excavator bulldozer that is easy to install, comprising a bulldozer body, a second telescopic assembly being provided on the right side of the bulldozer body, and two sets of fixed assemblies being provided on the right side of the second telescopic assembly, wherein the parts contained in the two sets of fixed assemblies are identical;

[0007] The fixing assembly includes an L fixing rod 1, the top of the L fixing rod 1 is fixedly connected to an L fixing rod 2, the top of the L fixing rod 2 is provided with a square hole, the outside of the L fixing rod 2 is provided with a round hole 1, a screw is inserted into the front of the L fixing rod 2, and a fixing pull rod is inserted into the square hole opened on the top of the L fixing rod 2. By setting the fixing assembly, specifically by hanging the L fixing rod 2 on the excavator mounting seat, when the L fixing rod 1 contacts the excavator mounting seat, the two fixing pull rods are inserted through the square hole at the upper end of the L fixing rod 2. At the same time, after the fixing pull rods are inserted, the L fixing rod 2 can be prevented from being offset due to the influence of gravity, which makes installation more convenient for the installer.

By setting the telescopic assembly, the bulldozer shovel can be moved forward or backward, and the size of the overall bulldozer shovel can be adjusted, so that the excavator can easily cope with road conditions of different widths.

[0009] Furthermore, two fixed cards are fixedly connected to the right side of the bulldozer shovel, and two round holes are provided on the two fixed cards. Pin shafts are rotatably connected inside the two fixed cards. A fixed triangular piece is fixedly connected to the right side of the bulldozer shovel body, and a hydraulic cylinder 2 is fixedly connected to the side of the fixed triangular piece close to the fixed card. The output end of the hydraulic cylinder 2 is rotatably connected to the pin shaft. By setting up the hydraulic cylinder 1, the effect of adjusting the angle of the bulldozer shovel is achieved, and the bulldozer shovel can achieve different functions.

By setting up the fixed frame 4, specifically, one end of the fixed frame 4 is rotatably connected to the circular shaft and the other end is fixedly connected to the bulldozer, the bulldozer can be made more flexible.

[0011] Furthermore, the right side of the fixing frame three is fixedly connected to the left side of the fixing frame two, the right side of the hydraulic cylinder one is rotatably connected to a round rod, and the front and back sides of the round rod are rotatably connected to the fixing frame one. By setting up the fixing frame one, the step of connecting the hydraulic cylinder one to the excavator mounting seat is omitted, making installation more convenient.

[0012] Furthermore, an excavator mounting seat is provided on the right side of the circular shaft, and two slots are provided on the top of the excavator mounting seat. Threaded holes are provided on the front and back of the excavator mounting seat. The top of the excavator mounting seat is connected to the fixed pull rod through the slots, and the front and back of the excavator mounting seat are threadedly connected to two screws through threaded holes. The right side of the L fixing rod 1 contacts the left side of the excavator mounting seat, and the inner side of the L fixing rod 2 contacts the outer side of the excavator mounting seat. By installing screws, the bulldozer device and the excavator mounting seat are installed more firmly without offset.

[0013] The utility model has the following beneficial effects:

[0014] The utility model provides a fixing assembly. Specifically, when installing the bulldozer, the L fixing rods on the front and rear sides can be hung on the excavator mounting seat first. After the L fixing rod one contacts the excavator mounting seat, two fixing pull rods are inserted through the square holes at the upper ends of the L fixing rods. After the fixing pull rods are inserted, the L fixing rod two can be prevented from being deflected by gravity, which makes installation more convenient for the installer.
