Description

This invention relates to earthmoving machines for developing trenches in frozen and dense soils and can be used in bar machines and trench excavators.

The known machine for cutting purposes includes a tacho with a frame, a disk milling cutter with incisors, a stripping auger, the blades of which are placed between the cutters of the milling cutter, the machine is equipped with a discharge auger mounted on the casing, and the blades of the stripping auger have flexible elements

The disadvantage of this device is that it does not provide high-quality cleaning of wide working bodies; In addition, this device is unacceptable for cleaning the cutting chains of bar machines and trench excavators, as the pattern of placement of incisors on bar machines and trench excavators can be asymmetrical and the screw can become jammed during operation. In addition, the presence of an autonomous drive for the sweep and discharge augers complicates the design, reduces its operational reliability, and increases the manufacturing cost. .

The closest technical solution to the invention to the technical essence and the achieved result is a mechanism for clearing and working elements of earth-moving machines, including a cleaner in the form of teeth mounted on a bracket and sized along the cutting line. And a shock-absorbing element C23.

However, this device also does not provide good quality cleaning work items earthmoving machines. .

The purpose of the invention is to improve the quality of cleaning.

The goal is achieved by the fact that in the mechanism for cleaning the working elements of earthmoving machines, including a cleaner in the form of teeth mounted on a bracket and placed along the cutting line, and a cushioning element, each tooth is made with a groove and provided with a guide bracket attached to it and installed before a groove, the teeth being mounted on the bracket by means of axles with axle diameter, limited axial displacement, and the damping element is made in the form of springs placed on the axes between the teeth.

Figure 1 shows the cleaning mechanism of the working elements of earthmoving machines, side view; figure 2 is a view of L in figure 1 ;, in fig.Z is view B in figure 1; in fig. with view B in FIG.

The cleaning mechanism of the working elements of the earthmoving machine includes a cleaner made in the form of teeth 1 mounted on bracket 2 and placed along cutting lines of incisors 3. Each tooth 1 is made with groove C and is equipped with a guide bracket 5 fixed in front of groove k on each tooth 1. Moreover, the teeth 1 are mounted 5 on the bracket 2 by means of axles 6 with the possibility of limited axial movement, and the cushioning element is made in the form of springs 7 placed on the axles 6 between the teeth 1. 0 To improve the cleaning, grooves A are made with sharp points Independent user faces of the chamfered cutting edges outwardly. The bracket 2 is attached to the gearbox 8 of the drive of the cutting chain 9 of the digging machine 5 of the trenching machine; not staggered according to their size.

The device also includes a baffle plate 11 placed in the lower part of the gearbox 1 on the side wall inclined to the outer side from the axis of movement of the working body (i.e. from the axis of the reflected trench}, which serves to remove the soil being cleaned from the incisors).

The mechanism works as follows.

In the process of digging the trench, the cutters 3 alternately pass into the grooves of the teeth 1, the sharp edge of which separates sticking soil from the incisors and fists (from the cutting elements), which roll down along the backplate;

J1 is removed to the dump beyond the limits of the excavated trench, the guide brackets 5 align the grooves of the teeth 1 with respect to the cutting elements (cutters 3 and the fists 10), which eliminates the jamming of the cutting elements in the grooves in case of their displacement from the cutting axis.

Springs 7 after reject 1 return it to its original state.

5, i.e. centered

cutting line cutters. , 8 depending on the pattern of placement of the incisors on the cutting chain 9, it is possible to change the placement of teeth 1 on axles 6 and bracket 2. The number of teeth 1 and their location on bracket 2 is selected depending on the width of the tool and on the arrangement of the incisors 3 Attachment design. assembly and disassembly

devices, which is achieved by bolting the bracket 2 to the crater or the guide frame of the working body.

The application of the proposed mechanism will expand the scope of application of trench digging machines in the development of frozen soils.
