Abstract

FIELD: construction.

SUBSTANCE: facility consists of a plough body, milling cutters 1, milling cutter rotation drives 5, bearing skids 2, and discharge openings of the milling cutters 4. The plough body has a double-layer wall, the inside of which all around the front edge has milling cutters installed 1 with a secured capability of contrarotation of the adjacent milling cutters. The plough surface of the body has a trapezium shape, and the front edge of the plough surface has a shape of semicircumference under which a cutting edge of the milling cutters projects 1.

EFFECT: power consumption reduction; enhancement of ditch cleaning as well as efficiency regarding problem cleaning zones.

Description

The invention relates to the working bodies of earth-moving machinery designed to clean canals, as well as channels of boggy rivers.

Known working body of a universal floating machine, including a pontoon, power plant, soil pump, suction slurry line, frame of the working body, milling soil cultivator [1].

However, the known working body does not provide for the cleaning of riverbeds and canals with a shallow depth of water, overgrown with reeds and shallow shrubs.

The closest technical solution to the invention are the working bodies of a pit machine and a plow canal cleaner, including milling cutters with blades mounted on parallel vertical shafts, forming annular cavities and discharge chutes, fixedly mounted in the annular milling cutter cavity [2], a plow channel digger, supporting sliding planes, bermo-cleaners , openers, upper dumps and lifting-dump surfaces [1].

The disadvantage of these executive bodies is the inability to use them when cleaning the canals in the presence of water, vegetation in the working area and high energy intensity during the work.

The purpose of the invention is the reduction of energy intensity, ensuring the efficiency of cleaning channels and increasing productivity in problem areas of cleaning.

This goal is achieved in that the device containing the plow surface in the form of a trapezoid is characterized in that the plow surface has a double wall, in front of which there are mills in front of the entire perimeter of the leading edge, and the direction of rotation of adjacent mills is always opposite, and the front edge of the plow surface is made in the form semicircles under which the cutting edge of the cutters protrudes.

Figure 1 shows the working body of the channel cleaner, front view; figure 2 is a section aa in figure 1; figure 3 - working body, top view.

The working body contains fourteen milling cutters 1 installed around the entire perimeter of the leading edge. The cutters are closed by the walls above and below, only the cutting edge protrudes. The supporting sliding elements 2 are located on the side of the developed channel profile. The guiding elements 3 are designed to supply the cut soil through the discharge window 6 of the working body to the transporting elements 7, the soil captured by the teeth of the cutter is ejected through the discharge windows of the cutters 4 during operation.

To ensure effective cleaning in problem areas and further transportation of soil, cutters cut the soil and roots of plants encountered in the cleaning process.

Relative to the longitudinal axis of the developed profile, the cutting plane is at an angle.

To exclude the winding of vegetation on the drive elements 5 of the mill 1, they are installed inside the double wall of the working body, thus protecting the drive element 5 of the mill 1 from above and below.

In terms of form and type of execution, the used milling cutters are almost similar to the milling cutters used in woodworking - sawing wood.

During operation, the cutters rotate towards each other, which eliminates the possibility of the appearance of torques in the horizontal plane. When the cutting part of the cutter enters the cutting zone, the cut soil enters the guide blades and, under the action of the pressure of the cut chip, moves to the conveying element. Thus, undercutting, feeding to the conveyor and forced shipment of soil from the working body.

The proposed design of the working body allows you to clean the rivers and canals in those places where traditional canal-cleaning machines and equipment cannot be used due to the shallow water depth that does not allow the use of a dredger, or in the presence of reed shoots.
