Abstract

The invention relates to earthmoving machinery and allows the operational and technological capabilities of the earthmoving machinery to be expanded. The working equipment includes a rigid frame 1, a thrower 4 and a sectional blade (CO), which is made of a central section 5 and side sections hinged with it 9. Before the corresponding sections 5 and 9 CO are loosening central 6 and hinged lateral loosening sections (PC) 7, 8 with teeth. The free ends of the lateral PCs 7, 8 with loose teeth are connected by hinge joints 11 and 12 with the free ends of the respective side sections 9, 10 CO. At the start of the machine, a cutting width is required. This is ensured by turning the hydraulic cylinders 13 of the sections 9 CO and PC 8 with the help of hydraulic cylinders. Then the hydraulic cylinders 3 lower the frame 1 until the teeth of the PC and the cutting knives CO are sunk into the ground. The soil loosened by the teeth of the PC is cut off with CO knives under unblocked cutting conditions. The soil, which is cut by the knives of the CO sections 9, moves along their dump surfaces to section 5 and through the loading window in it enters the thrower 4, with the help of which it moves to the side of the developed strip. 4 il.

Description

The invention relates to earthmoving equipment, in particular, to working equipment, with a variable cutting width, which can also work on frozen soils.

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

Figure 1 shows the working equipment of the earthmoving machine, top view; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1; figure 4 - section bb In Fig, 1.

The working equipment of the earthmover includes a base frame 1 pivotally connected to the base machine 2, and a hydraulic cylinder 3 for controlling the working equipment mounted between the frame 1 and the base machine 2.

The frame 1 is equipped with a thrower 4. In front of the thrower there is a sectional blade and sections with loosening teeth, central sections 5 and 6, respectively, which are parallel and rigidly fixed to frame 1. To the central section 6 with loosening teeth with each side sides using vertical hinges attached side sections 7 and 8 with loose teeth. To the central section 5 of the blade, on each side of the blade, lateral ground guide sections 9 and 10 of the blade are attached by vertical hinges. The free ends of the side sections 7 and 8 with loosening teeth are connected by hinge rods 11 and 12 with the free ends of the corresponding side sections 9 and 10 blades. To control the position of the side sections with loosening teeth and the blade, hydraulic cylinders 13 are mounted on the frame. loosening teeth are made in the form of a comb. In the central section 5 of the blade is loaded

a window with a grid installed therein for the passage of soil into the thrower 4.

The side sections with loose teeth are installed parallel to the respective side sections of the blade, and each pair of them between them is positioned with an increase in the distance between the pairs away from the throwers.

The equipment works as follows.

Claims (1)

Installed by hydraulic cylinders 13, a cutting width or lay-out is required by turning the corresponding pairs of blade sections and with loosening teeth. Then the hydraulic cylinder 3 lowers the frame 1 until the loosening teeth of the sections and the cutting knives of the blade are buried in the ground. At the same time, a greater penetration of the knives of the section blade is constructively ensured. The ground loosened by the teeth is then cut off with a section blade. At the same time, the blades of the blade work under conditions of unblocked cutting. The soil cut by the knives of the side sections of the blade, due to their oblique position relative to the cutting direction of the soil, will move along the dump surfaces to the center section of the blade and through the loading window into the thrower 4, from where the soil will flow to the right or left side of the developed strip ground. Invention Formula The working equipment of the earthmoving machinery, including the carrier frame, the thrower mounted on it and the sectional dump located in front of it with the side soil-guide sections, which are connected with the carrier frame and can be rotated in the plan, are driven and controlled to increase distances between them in the direction from the scoop, differing in that, with the aim of expanding the operational and technological capabilities, the blade is equipped with a central section with a front section located in front of the thrower a receiving window, which is rigidly fixed to the frame, and with which the rear ends of the blade sections are pnarnically connected, and the loosening sections located in front of and parallel to the corresponding sections of the blade The central ones are rigidly fixed to the frame, and the lateral pivots are connected by rear ends to the central section and front ones by means of hinge bars with the front ends of the side sections of the blade, while the plane of the hinge axes for each hinge is parallel to the plane of the hinge axes the corresponding side sections of the blade and the loosening section — to their central sections.
