Description

The invention relates to earthmoving equipment, and in particular to open-ended rotary working bodies, designed to dig trenches and remove soil from it.

The aim of the invention is to increase the productivity of the working body by increasing the outflow capacity and improving the quality of cleaning work elements.

FIG. 1 shows the working body of the general view; in fig. 2 is a view A of FIG.

The working body includes a drive rotor 1 with a tapered rim 2, on which the working elements 4 with cutting parts 5 and the transporting surface 6 are hinged with the help of fingers 3. The free ends of the working elements are placed between turn stops made in the form of stops 7 mounted on the conical rim of the rotor.

The front face of each cutting part 5 is located at an acute angle to the generatrix of the tapered rim 2, and one of the sides of the conveying surface is placed with the possibility of contact with the tapered surface of the rim.

The device works as follows.

When the rotor 1 rotates, the working elements, located with the help of fingers 3 on the conical surface of the rim 2, will open the trench with their front face. The soil developed by the cutting parts 5 accumulates on the transport planes and is carried to the ground surface and under

its own weight is showered on the inclined front plane of the working elements 4 on the trench curb.

At the same time, at the exit of the working elements 4 from the bottom, the reaction from the cutting force becomes equal to zero and, under the influence of gravity and centrifugal forces, they rotate around the finger 3, which causes the free tail ends to hit the stops 7 and the remaining soil drops from the working surfaces: elements four.

rmula of invention

F o

The working body of the earthmoving machine, including, a rotor with hingedly connected with it working elements having cutting parts and transporting surfaces, and rotational restraints, characterized in that in order to increase productivity by increasing the outgoing capacity and improving the quality of cleaning the working elements , the rotor is made in the form of a tapered rim, while the front face of each cutting part is located at an acute angle to the generatrix of the tapered rim, one of the side faces of the conveying surface is placed with the possibility of contact with the conical surface of the rim, and the other is located in the plane of the lateral sides of the rotor, and the stops are made in the form of stops fixed to the conical rim to accommodate between the free ends of the working elements.

Claims (2)

Claim The working body of the digging machine, including the rotor with pivotally connected working elements, the elements of which are placed between the rotation limiters, made in the form of stops 7, mounted on the conical rim of the rotor. The front face of each cutting part 5 is located at an acute angle to the generatrix of the conical rim 2, and one of the sides of the conveying surface is placed with the possibility of contact with the conical surface of the rim. The device operates as follows. When the rotor 1 rotates, the working elements located with the fingers 3 on the conical surface of the rim 2, They will open the trench with their front face. The soil developed by the cutting parts 5, accumulates on the transporting planes and carried to the surface and under Type A
