As one of the important working devices of the bulldozer, the ripper greatly expands the working range of the bulldozer and improves the working efficiency of the bulldozer. Therefore, more and more people pay attention to it. the

At present, in the existing multi-tooth rippers, several ripper teeth that are basically the same or have very little difference are horizontally evenly distributed on the main beam, and the tooth tips are on the same straight line after being installed. This type of ripper has a large resistance to loosening the soil, and the effective width of the tooth surface for loosening the soil is limited by the maximum resistance to loosening the soil, so it cannot be too wide, and the efficiency of loosening the soil is low. the

A multi-tooth ripper for a bulldozer, comprising a soil splitting tooth, a main beam and a gear bar fixing sleeve, the gear bar fixing sleeve is installed on the main beam, the multi-tooth ripper for a bulldozer also includes a soil breaking tooth, and the soil breaking tooth is assembled on one side of the main beam In the tooth bar fixing sleeve in the middle, the soil breaking tooth is assembled in the tooth bar fixing sleeve at the other two ends of the main beam; the ground breaking tooth includes a ground breaking tooth tooth bar, a soil breaking tooth guard plate and a ground breaking tooth tip insert, wherein Cutter Guards and Cutter Tip Inserts are mounted on the Cutter Shank. the

The outer surface of the ground-breaking tooth guard plate is processed into a convex rib structure, and the two sides of the convex rib are smooth and symmetrical curved surfaces along the convex rib, and the angle formed by the two symmetrical curved surfaces is 80° to 120°; the ground-breaking tooth The tooth tip insert is processed into an acute-angle pyramid structure; an assembly hole is opened on the ground breaking tooth bar, and the ground breaking tooth guard plate and the ground breaking tooth tip insert are assembled on the ground breaking tooth tooth bar through an elastic pin shaft and an elastic fixing pin. the

The utility model improves the structure of the multi-tooth ripper of the traditional bulldozer. The structure is reasonable, the working resistance of the bulldozer in the loosening operation is reduced, and the efficiency of loosening is improved. The device has simple structure, strong practicability, and is convenient for popularization and use. the

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further. the

Detailed ways

The specific embodiments of the present utility model are provided below, and it should be noted that the present utility model is not limited to the following specific embodiments, and all equivalent transformations done on the basis of the technical solution of the application all fall into the protection scope of the present utility model. the

According to the above technical scheme, as shown in Figure 1 and Figure 2, this embodiment provides a multi-tooth ripper for a bulldozer, including a soil cracking tooth 1, a main beam 2 and a tooth bar fixing sleeve 3, and the tooth bar fixing sleeve 3 is installed on the On the main beam 2, the multi-tooth ripper of the bulldozer also includes a soil breaking tooth 4, which is assembled in the gear rod fixing sleeve 3 in the middle of one side of the main beam 2, and the soil cracking tooth 1 is assembled in the two ends of the other side of the main beam 2. In the tooth bar fixed sleeve 3, the described ground breaking tooth 4 comprises a ground breaking tooth tooth bar 41, a ground breaking tooth guard plate 42 and a ground breaking tooth tip insert 44, wherein the ground breaking tooth guard plate 42 and the ground breaking tooth tip insert 44 are installed on On the earth-breaking gear rack 41. the

The outer surface of the ground-breaking tooth guard plate 42 is processed into a rib structure, and the two sides of the rib 43 are smooth and symmetrical curved surfaces along the rib 43. The angle formed by the curved surface is 80° to 120°; the described earth-breaking tooth tip insert 44 is processed into an acute-angle pyramid structure; an assembly hole 45 is opened on the earth-breaking tooth rod 41, and the earth-breaking tooth guard plate 42 and the earth-breaking tooth The tooth tip insert 44 is assembled on the ground breaking tooth rack 41 through the elastic pin shaft and the elastic fixing pin. the

In the utility model, the soil-breaking teeth 4 are installed in front of the main beam 2, and the soil-breaking teeth 1 are installed behind the main beam 2. , the tooth tip of the earth-breaking tooth is always in front of the tooth tip of the earth-breaking tooth. And because the tooth bar 41 of the ground breaking tooth is relatively thinner than the tooth bar of the ground breaking tooth, the tooth tip of the ground breaking tooth 4 is an acute-angle pyramidal tooth tip, and the ground breaking tooth guard plate 42 is processed into a convex rib structure, so it has less resistance when working. It is easier to draw a "deep ditch" on the job object, thus destroying the overall structure of the job object. After the overall structure of the work object is destroyed by the soil breaking tooth 4, the resistance when it is loosened and cracked will be greatly reduced, so the soil breaking tooth 1 installed behind the main beam 2 can efficiently loosen it with a wider working area. , Crack operation. the

形的宽型护板，整体结构使得裂土齿1在最大裂土阻力允许的情况下，加大了其有效松、裂土面积，以提高松土器的作质量及作业效率。  The installation position of the soil breaking tooth 1 is behind the ground breaking tooth 4. The tooth bar of the soil breaking tooth 1 is wider than the tooth bar 41 of the soil breaking tooth. for

The wide-shaped guard plate and the overall structure make the soil ripper 1 increase its effective loosening and cracking area under the condition that the maximum cracking resistance allows, so as to improve the working quality and working efficiency of the ripper.

The tooth tip inserts and guard plates of the ground breaking tooth 4 and the ground breaking tooth 1 are all made of wear-resistant materials with high hardness, high strength and certain plastic toughness, and the tooth tip inserts and guard plates are made of elastic pins and elastic pins. The fixed pin is fixed with the gear rod for easy replacement. the
