Description

Technical Field

[0001] The utility model belongs to the technical field of loaders, and in particular relates to a highway construction and maintenance loader. Background Art

[0002] Loaders are earthwork machines widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. They are mainly used to shovel bulk materials such as soil, sand, lime, and coal, and can also do light shoveling of ore and hard soil. By replacing different auxiliary working devices, they can also do bulldozing, lifting, and loading and unloading of other materials such as wood.

[0003] The existing highway construction and maintenance loaders still have some defects. A shovel tooth is set at one end of the bucket, and the shovel tooth and the bucket are mostly fixed by welding. When the shovel tooth breaks, it is troublesome to repair. The bucket needs to be cut and polished, and then new shovel teeth need to be welded on, which is time-consuming and laborious. For this reason, we propose a highway construction and maintenance loader. Utility Model Content

[0006] Preferably, a guide block is provided on one side of the mounting plate, a guide groove is embedded in the inner wall of the mounting groove, and the guide block and the guide groove are slidably connected.

[0007] Preferably, a second fixing hole is embedded in the surface of the mounting plate, and the fastening bolt is fixed by interpenetration with the second fixing hole.

[0008] Preferably, a hydraulic rod is provided at one end of the bucket, and the hydraulic rod is rotatably connected to the bucket.

[0009] Preferably, a connecting block is provided at one end of the hydraulic rod, and the hydraulic rod and the connecting block are rotatably connected.

[0010] Preferably, a cab is provided on the top of the loader body, and rollers are provided on the bottom of the loader body.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The installation groove, installation plate, shovel teeth, first fixing hole, fastening bolts and nuts are provided to facilitate the replacement of shovel teeth. When the shovel teeth are broken, it is only necessary to insert the installation plate into the installation groove, and then use the fastening bolts to pass through the two fixing holes and use the nuts to fix the fastening bolts to complete the replacement.

[0013] 2. Through the provided guide block and guide groove, when installing the shovel teeth, the mounting plate is inserted into the mounting groove, and the guide block slides into the guide groove at the same time, thereby improving the stability of the mounting plate and making it less likely to shake.
