Abstract

The invention relates to earth moving machinery and can be used to move bulk materials. The goal is to increase productivity by ensuring efficient material handling. The thrower includes a driving rotor 2 mounted with a discharge nozzle, a rotor 2 with blades 3. On the casing 1, through the axis 4, a guide wall (HC) 5 is movably fixed with a mechanism 6 changing its position in the vertical plane. The inner surface of the HC 5 has longitudinal ribs 7 mounted on the axles and can be rotated by means of hydraulic cylinders. The axes are installed perpendicular to the HC 5 plane. The longitudinal ribs 7 are coated with wear-resistant material with a low coefficient of friction. The rotating rotor 2 blades 3 captures the material and throws it onto the HC 5, the position of which is established by the mechanism 6 changing its position. The position of HC 5 and the longitudinal ribs 7 gives the material a certain direction and concentration of the flow, allowing control of the loading of the material on the transporting means. 1 h. n. f-ly, 3 ill.

This invention relates to earth moving throwing technology and can be used to move bulk materials.

The purpose of the invention is to increase productivity by ensuring efficient material loading.

FIG. 1 shows the thrower, a general view; in fig. 2 - the same, top view; in fig. 3 is a cross section A-A in FIG. 1. The thrower includes a driving rotor 2 mounted with a discharge nozzle of a drive rotor 2 with blades 3. On the casing 1, through the axis 4, a guide wall 5 is movably fixed with a mechanism 6 changing its position in the vertical plane. On the inner side of the guide wall 5, longitudinal ribs 7 are installed, which are mounted on axles 8 and can be rotated by means of, for example, hydraulic cylinders 9. Longitudinal ribs 7 have a coating 10 of wear-resistant with a small coefficient of material friction, and axes 8 are installed perpendicular to the plane of the wall.

The work of the metatatel is as follows.

and the concentration of the flow allows control of the loading of the material onto the transporting means, preventing it from spreading to the side. The implementation of the lateral sides of the longitudinal ribs of the trapezoidal shape helps to preserve the concentration of the flow and its directionality at the exit of the scoop, at the moment when the stock of the kinetic energy of the flow and its velocity sharply decrease.
