Description

The invention relates to a digger technique and is intended for digging trenches in soils of various categories.

Known working body of the trench machine, including mounted on the shaft of the rotor mounted on its periphery of the cutting elements and the pickup [1J.

The disadvantage of this working body is its low-productivity, especially in loose soils.

The closest technical solution to the invention is the working body of a digging machine, including a shell mounted on a shaft hub 15 with cutting elements fixed around its periphery [2J.

The disadvantage of this working body is low productivity and high metal consumption. ₂ 0

The purpose of the invention is to increase productivity and facilitate unloading of the soil.

The goal is achieved in that the working body zemleroy- _{2 May} hydrochloric machine, comprising a hub mounted on a shaft sleeve is fixed to the periphery thereof rezhuschii elements shell is made of interconnected radial, θ sections defined by their width crossarms, on which are arranged cutting elements, while the traverses are installed at an angle to one another and are interconnected.

In FIG. 1 shows a working.op- ³³ gun, side view, in FIG. 2 is the same, front view) in FIG. 3 is a section AA in FIG. 1.

The working body includes a rim mounted on the drive shaft with a hub of 40, made of radial sections connected to each other, ¹ section 2 with cross beams installed along their width .3, on which cutting elements are placed 4. Traverses ”3 are installed at an angle one to the other and are interconnected, forming a zigzag disk. Traverses 3 are alternately tilted at an angle about the axis of rotation of the working body.

The angle of inclination of each traverse according to the conditions of effective unloading 40-45. Traverses 3 form remote containers (buckets) with the surface of section 2. The linear arrangement of the teeth 4 on the verge of the beam 3 provides cutting of the soil at different radii: the outer teeth have a larger cutting radius. Given the slope of the traverse, this achieves unlocked and oblique cutting, which reduces the specific energy consumption of soil development. Installing a zigzag disk on the hub increases the rigidity of the design of the working body.

The working body can work in two modes of unloading - gravity and centrifugal. In the gravitational unloading mode, the soil moves laterally in inclined sections and a barrel-shaped hub. In the centrifugal unloading mode (peripheral speed 4-5 m / s), the soil is directed at an angle of 100-120 ° in the direction of supply of the working body. on and scattered to the sides, forming a parapet.

The bucket working body is simple in design, provides soil development in various unloading modes, in combination with unlocked and oblique cutting.
