Description

one

The invention relates to the field of construction and transporting machines such as soil throwers.

Known rotary thrower, including accelerating rotor and unloading device. The acceleration of the soil in the thrower is carried out by the joint action of centrifugal forces and friction forces, unloading by changing the direction of the flow of the soil and removing it from the throwers 1.

The disadvantage of such a scoop is sticking of the soil during unloading, which reduces the performance of the scoop and the range of movement of the soil.

The closest technical solution is a rotary thrower, including a rotor with a concave curved inner surface, a fixed axis with a radial bracket, on which is mounted the unloading disk with a drive mechanism 2.

A disadvantage of the known construction is the high power consumption of unloading and the presence of an independent additional drive on the unloading disk.

The aim of the invention is energy intensity and an increase in the ground sweeping range.

The goal is achieved by the fact that the drive mechanism of the unloading disk

It is connected to the rotor by means of a mechanical transmission, the gear ratio of which is equal to the ratio of the maximum radius of the inner surface of the rotor to the radius of the unloading disk, while the mechanical transmission can be made of a V-belt transmission, the output shaft of which is mounted on an additional bracket, which is equipped with a radial bracket.

FIG. 1 shows the proposed thrower with a conditionally removed casing, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; on

FIG. 4-disk unloading device, a cut along the axis.

The soil thrower includes a rotor 1, made with a curved inner surface and mounted on a fixed axis 2 by means of axle 3 and bearings 4. The rotor is driven through gear 5, mounted on axle 3 of the rotor. The radial bracket 6 of the discharge device is rigidly fixed on the axis 2.

The disc 7 of the unloading device is mounted on the bracket 6 by means of an 8 n shaft of an angular contact bearing 9. The disc drive 7 includes a pulley 10 fixed on the rotor 1, an axle gear 11, a pulley 12 n bevel gear 13

14. The bevel gear 13 is fixed to the intermediate shaft 15, which is mounted on the additional bracket 16 by means of the radial bearing 17 and the radial-thrust bearing 18. The gearing of the bevel gears is adjusted using the cover 19 and interchangeable gaskets 20. The tension of the V-belt transmission is carried out by means of a roller tensioner 21. The transmission mechanism is covered by a casing 22, conventionally shown by a dashed line. The gear ratio of the mechanical transmission, including its V-belt and bevel gear stages, is equal to the ratio of the maximum radius of the inner surface of the rotor 1 to the radius of the disk 7.

The work of the metatatel is as follows.

The soil enters the rotor 1 in the direction of arrow B and accelerates due to the action of friction forces and centrifugal forces up to a speed equal to the peripheral speed of the rotor. In the ejection zone, the soil flow moves along the surface of the disk 7, changes its direction of movement, and is ejected from the rotor 1 with a further flight along a ballistic trajectory. The forced rotation of the disk is carried out with a maximum linear velocity equal to the maximum linear velocity of the inner surface of the rotor.

The proposed implementation of the scoop reduces the friction loss of the soil over the surface of the disc of the unloading device, providing an increase in the ground sweeping distance and reducing the energy intensity of the sweeping by reducing the soil prism.
