Description

I

The invention relates to earthmoving, mechanical engineering, in particular to the working bodies of the trenchers.

A well-known excavator-throwing machine, including traction and mounted on the traction frame, is a pipe-throwing body in the form of a pipe, which serves as a cutting tool, as well as a thrower, one end of which with a hole for ejection of soil is hinged to the disk - a flywheel, which is eccentrically mounted relative to the drive, and the other end of the pipe, open from the bottom, is provided with a knife and is connected to the traction frame by means of a two-axis hinge tU

The disadvantage of this construction is that the pipe is quickly clogged with soil, especially wet, the productivity is low, the impossibility of obtaining even slopes and the bottom of the trench, the inability to open the ditches of a given profile in one pass.

In addition, after the digging of ditches, a soil roller is deposited at its edge, and in order to level, a second tire, such as a bulldozer, has to be put into operation, which increases the capacity and energy consumption of each cubic meter of land and its cost.

Known attachments to the machine for the development of soils, including the frame mounted on

To it is a cutting body, on the drive shaft of which a thrower is mounted, kinematically connected with the metat-. a blade accelerator, blade with a knife, mounted on the cutting body and having an ISF2J profiling wing.

However, this working body is characterized by insufficient productivity of the working body.

The aim of the invention is to increase the productivity of the working organ, hook and quality of work.

The goal is achieved by the fact that the blade is made with a hole 39 on both sides of which the cutting body and the thrower are placed, equipped with a leading mill with a shaft parallel to the shaft of the cutting body and kinematically connected with it, while the blade is equipped with an additional accelerator placed symmetrically with respect to the vertical plane passing through the longitudinal axis of the working body with the main accelerator. FIG. 1 shows a working body, a general view; in fig. 2 - the same, front view. On the frame of the working body, a cutting working body is installed, made in the form of a milling cutter 1, on the drive shaft of which a thrower 2 is mounted, consisting of an elastic rubber ring 3, a bending roller k with a reversing mechanism 5 of the drive 6 with gears 7, 8 and 9- A hole 10 having a hole, installed between the mill 1 and a thrower 2, is mounted a leading additional milling cutter 11, kinematically connected with the FRY ZOY 1. The blade 10 is hinged to the bottom frame of the base frame with the help of the drum 12 t. Hydraulic cylinders are provided for deepening and deepening the blade. 13- On the dump, H-throwers with engines 15 are installed. For profiling the bottom of the ditch, 10 profiling wings 16 are provided on the blade 10. Electroosmosis network from the basic generator is connected to the blade cutters 1 and 11 The blades of the blade 10 are equipped with a pendulous, angular position sensor connected to the control panel of the base machine, and a strain gauge is mounted on the blade connected to the control panel of the base machine. The setting-on of the blade of the rotary encoder of the angular position provides automatic control of the angular movement of the working mechanism in a vertical plane, perpendicular to the direction of movement of the grouser, which ensures that the working mechanism is set in this position. The proposed earthmoving machine for the machine works as follows. Depending on the required distance of ground sweeping, one of the rotor-blade vanes with its 4 electric motor 15 is fixed in the working position either in the position corresponding to its joint work with the main elastic-ring thrower 2, or both throwers 14 with its own the engines 15 are pushed back to the extreme position and then only the main thrower works. 2. Depending on the need to move the ground, the main thrower 2 is reversed with a corresponding roller tilting by means of mechanism 5- To spread the soil by throwers across the surface using the drive speed box 6, the variable speed rotation circuit of the throwers is turned on, and the ground is spread over different distances. When the chassis of the base machine is turned on, the drive 6 is simultaneously activated and two milling cutters 1 and P and the main thrower 2 are set in motion with gears 7, 8 and 9, and if necessary, one of the rotary-blade throwers 1 is turned on by its electric motor 15- In addition, an electro-osmic system is activated, for which a voltage is applied to both the milling cutters 1 and 11 and the tooth of the blade (negative pole), and to the thrower 2 (positive pole). And with the help of hydraulic cylinders 13, the dumping of the blade 10 into the ground to a predetermined depth value begins. Thus, as small a milling cutter 11 removes the soil from below, the underlying layers of the soil lose their viscosity, te4 facilitates the operation of the main milling cutter 1 and therefore its step can be increased, which leads to an increase in productivity. And the electro-mathematical system reduces the resistance of the soil to cutting and prevents sticking of the soil. With the help of tg 12, hydraulic cylinders 13 and hinged attachment, the blade 10 is installed vertically taking into account the depth of cut. With the horizontal position of the tg 12 and with the vertical position of the blade 10, the digging of the ditch is provided to a full depth of two cutters. If it is necessary to dig ditches to a shallower depth, for example, into one cutter, the pull-rods 12 are set obliquely, the hinge of the fastening is loosened, the blade is lifted and re-installed in the vertical position, after which 59 the hinge is again firmly locked. On slots 12 in an inclined position, it sends the corresponding readings to the cabin of the base machine, corresponding to the value of a given depth. The blade takes 10 to the ground. Consequently, with one heap, one can dig ditches of several depths. And when changing the heap to the heap of another profile, keeping all the other mechanisms, it is possible to expand the possibilities of digging ditches of different sections. This provision unifies and expands the design capabilities of the new machine. And to protect the working bodies from boulders, stones and stumps that are not developed by cutters, a strain gauge mounted on the blade 10 during overloads disables the forward movement of the machine and the rotation of the cutters. The invention The working body of the earth-throwing machine, including a frame with a mustache The cutting body mounted on it, on the drive shaft of which a thrower is mounted, kinematically associated with the thrower-accelerator, blade with a knife and profiling wings, characterized in that, in order to increase the performance of the working body and improve the quality of work, the blade is made with the hole, on both sides of which the cutting body and thrower are located, is equipped with a leading cutter with a shaft located parallel to the shaft of the cutting body and kinematically connected with it, while the blade is equipped with an additional thrower -uskoritelem placed symmetrically about a vertical plane passing through the longitudinal axis of the working body with the main thrower accelerator.
