Description

. J

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

The closest in technical essence and the achieved result to the invention is the bulldozer equipment containing the pusher bar J with the main blade, the front jaw pivotally connected with the blade bracket with the claws and the additional hinged knife and the hydraulic cylinders of the control jaw jaw j.

A disadvantage of the known dozer equipment is the narrowing of technological possibilities, due to the fact that the design, due to the impossibility of adjusting the height of the position of the additional knife, does not allow two-digging with the cutting edges of the jaw and the blade of the bulldozer mounted on the main blade. , and also due to the fact that there is no possibility of adjusting the jaw grip to hold long objects of different diameters. In addition, in the well-known solution, it is impossible to loosen the ground with the jaw when the base machine moves in reverse.

The purpose of the invention is the expansion of technological capabilities.

This goal is achieved by the fact that bulldozer equipment containing pushing bars, a blade with a main knife, anterior jaw pivotally connected to the blade arms with jaws and an additional hinged knife, and hydraulic cylinders for jaw control, equipped with hinged means attached to the arms, are provided with imitation hinges on the jaws and in accordance with the set of imitation hinges on hinge brackets attached to the jaws; control mounted housings on the back of the blade, and rods connected to one end of the rocker arms, which the other ends are connected to the clamps, p and that the grippers have a number of mounting holes for adjusting compound rockers.

5 Bulldozer equipment contains pushing bars 1, blade 2 with knife 3 and the front jaw with grippers 4, equipped with a hinged knife 5 in the lower part. Grips 4 are controlled

the hydraulic cylinders 6, the grippers 4 are hingedly connected to the rocker arms 7, controlled by the hydraulic cylinders 8, and have a number of mounting holes 9 for adjusting the position of the jaw. The rocker arms 7 are located on both sides of each gripper 4.

Bulldozer equipment operates as follows.

The force from the pushing bars 1 is transmitted to the blade 2 and when the blade 3 and blade 5 are inserted, the digging process takes place in the ground (Fig. 2. The hydraulic cylinders 6 and 8 can be set, the blade 5 of the front jaw can be set at the same level with a knife 3 blades 2, which is required when performing planning and cleaning works. In this case, it is possible to capture long items of different diameters. Controlled by hydraulic cylinders 8 rocker arms 7, you can change the position of grips 4 relative to the blade 2 and at the same time opportunity There is a grip of long objects with diameters DJ (Fig 2) or 0 Fig 2). In the development of strong soils, when it is necessary to loosen the soil, the grips 4 (Fig 3) are installed using the mounting holes 9 in the lowermost With this design of the working equipment, it is possible to loosen the soil when the bulldozer is moving in reverse. Changing the depth of loosening is achieved by changing the position of the rocker arms 7. To reduce the energy intensity of the soil development process and increase The performance of blade 3 of blade 2 and knife of front jaw 5 by changing the position of rocker arms 7 and holes 9 are set at the same level and at a certain distance from each other (Fig. b) or at different levels (Fig. 4), which provides two-knife digging system. At the same time, the process of cutting the soil with the knife 5 is taken out from under the soil prism, thus reducing the energy intensity of the digging process, and the grippers 4 at the same time ensure the retention of the drag prism j, which has a positive effect on the productivity of land works. The proposed bulldozer equipment can carry out the development of soil using various technologies. When working on solid soils, only the jaw 5 knife is engaged, which ensures good penetration of the knife system into the soil and the possibility of developing solid soils. The chips are cut out with an area of F. (Fig. 7). At the same time, the cutting height with an additional knife (Fig. 2 can be varied by controlling 74 rocker arms 7 using hydraulic arms 7, which is required to eliminate losses of the soil moving into the gap between the blade 3 of the blade 2 and the ground surface of the soil. Knives 3 and 5 have At one level, soil chips can be cut out of the same thickness (Fig. 9) but of different areas - knife 5 cuts chips of area F, and knife 3 makes FJ,. Soil development is possible (Fig. 8). When knife 5 cuts soil chips area F provides only a good introduction of the blade 2. and 3 cut out with a knife The main part of the soil is Fg and cleaning and planning works are carried out. Such equipment allows the development of soil, cut out stepped soil chips, the area of chips, cut out with a knife 5, and I-J7 - the area of chips, cut out with a knife 3 of blade 2. Insertion dozer equipment of hydraulically controlled rocker arms connected to the jaw claws through a series of mounting holes allows the equipment to expand its technological capabilities both in terms of soil treatment and in length material. i FIG. 5 N С
