Description

one

This invention relates to lifting machines.

Basically auth. St. No. 542835 describes a device for loading bulk materials, comprising a drive auger, rotatable cranks located eccentrically relative to the casing, which are pivotally connected to the blades 1, located in the casing.

A disadvantage of the known device is that when using the device, one indentation of material occurs with each blade in one revolution of the blades. In this case, the supply of material to the auger occurs unilaterally, which leads to bending of the auger and uneven wear of the casing and the auger, and to a decrease in loading performance.

The aim of the invention is to increase loading performance.

The goal is achieved by the fact that the casing is made sectional of two parts interconnected with the gap of the upper part and rotates against the drive of the lower part relative to it, while a seal is installed in the gap.

FIG. 1 shows the device, obsh, iy view; in fig. 2 is a section along A-A of FIG. one; in fig. 3 is a section along BB, FIG. 2; on

FIG. 4 - the trajectory of the extreme point of the blade during rotation.

The device for loading bulk materials includes blades 1, a link to the front 2 (for example, a pulley) of the engine torque rigidly fixed on the lower part of the casing 3, at the bottom of which there is a cross 4 with an axis 5 and cranks 6. In the upper part of the casing it has 10 bearing node 7, the body of which

connects rotating and fixed

parts of the housing in the gap between them

set seal 8.

A device for loading bulk materials operates as follows.

Rotate the blades 1 with cranks 6 around the axis 5 with the speed rti. At the same time rotate through the transmission link 2 the cover 3 of the screw with the crosspiece 4 and the axis 5

20 in the bearing support 7 with the rotation speed “2 in one or in different directions with the rotation of the blades. The gap between the rotating lower part of the screw casing 3 and the fixed upper part is closed by a seal 8.

At the same time, the extreme point of the blade 1 is in a complex movement — rotation about a fixed axis 5 and in a portable rotational movement along with

30 casing 3 cross 4 and the axis 5. This

allows to carry out a circular loading of materials into the device casing, as well as in

depending on the ratio - and direction "2

of rotation (Fig. 4), increase the number of material indentations during one revolution of the blade, and thereby increase the loading performance at the same number of revolutions of the arm as in the device-prototype.

So, for example, when the ratio is - -

“2

: - and the rotation of the blades and the casing with the crosspiece in one direction, the loading capacity increases by 3 times, and when rotated in different directions, increases by 5 times, etc.

The device increases productivity of loading approximately in 5 times in comparison

With the known device m gives a significant economic effect.
