SU975920A1 - Bulldozer equipment - Google Patents

Description

The invention relates to the construction-road machines, namely, to earth-moving machines such as bulldozers.

Known bulldozer equipment, including the blade, the pushing frame, struts and pushers. The rotation of the blade in the plan is carried out manually by swapping the pushers [1].

The disadvantage of dozer equipment is that when turning the heap there is a possibility of overturning the heap, and this reduces the safety of work.

The closest to the proposed is the equipment, including a blade with a spherical holder, pushing the frame located in the holder. head, pushers and dumping tilting limiter when turning / last in plan [2),

The disadvantages of it is the complexity of the design of the stopper tipping over the blade when turning it in the plan, including a screw coupler, a protrusion on the blade and an emphasis on the hinge connecting the blade to the frame.

The aim of the invention is to simplify the design.

This goal is achieved by the fact that the lower part of the spherical holder

It has an internal flat platform, and the dumping overturning limiter is made in the form of a stop located on the transitional base of the ball: boat, with the possibility of interaction ’with the flat area of the spherical cage.

Bulldozer equipment includes blade 1, pusher frame 2, pusher15 3 and screw braces 4. Blade 1 is connected to the pushing frame with a ball head 5 located in cage 6 of blade 1. The lower bearing surface 7 of the cage 6 is made flat. The transitional base 8 of the ball head 5 has an abutment 9. A lid 11 is attached to the butt of the side 6 with a side 10. The pushers 3 are connected to the blade 1 and to the supports 12 of the pushing frame.

fits to the lower support surface of the holder b, preventing tilting. The execution of the surface 7 of the flat allows the rotation of the blade in the plan.

The implementation of the stop on the basis of the ball head and the flat wall on the Bottom surface of the spherical cage allowed us to simplify the design of the dump tipping stop.

Claims (1)

Claim, Bulldozer equipment, including a spherical cage blade, a pushing frame with a ball head located in the cage, pushers and a crown}} § dump blade tipping device rotation of the latter in plan, which is characterized by the fact that, in order to simplify the construction, the lower part of the spherical cover has an inner flat area, and the dumping tilting limiter is made in the form of a stop located on the transitional base of the spherical head with the possibility of interaction with a flat spherical cage.
