Description

A useful model for the selection and throwing of peat raw materials relates to the field of mining engineering, in particular, to devices for the extraction of peat raw materials and can be used in the extraction of peat raw materials by the open-cut method.

Known fertilizer thrower rotor (copyright certificate SU No. 305839, published 06/11/1971), consisting of blades made of spring steel, held by a retaining ring and clamping discs.

The disadvantage of this device is the content of small metal parts capable of corrosion in a humid acidic peat environment, which limits the scope of its application.

Known rotor soil thrower (copyright certificate SU No. 208546, published on 28.12.1967), consisting of disks connected by blades, between the blades are movable blades that can rotate around the axes.

The disadvantage of this device is a decrease in performance due to soil spillage from the blade and high energy consumption of the process due to increased friction of the soil against the thrower casing.

Known rotary thrower (inventor's certificate SU No. 1712273, published 02.15.1992), made in the form of a vertical disk on which the blades are radially fixed, at the end of the blade is an L-shaped cut, and on the hinge support is a soil-retaining blade with a roller.

The disadvantage of such a thrower is the high energy intensity and unreliability in the operation of the blades made in the form of L-shaped notches as a result of work on a peat deposit.

Known paddle thrower soil (copyright SU No. 174135, published 06/08/1965), consists of a solid disk of a welded structure, mounted on a bracket with two bearings, two rows of radial blades are welded to the disk: accelerating and ejection.

The disadvantage of this device is a large number of blades and a small distance between them leading to a small capture of peat raw materials, thereby the productivity of this thrower in a peat deposit will be low, and the energy consumption of this device is high.

Known fertilizer thrower rotor (copyright SU No. 264835, published 01/01/1970), adopted as a prototype , contains a rotor of blades fixed on the hub, rollers limiting the displacement of the blades in the plane of rotation and discs limiting the displacement in the axial direction.

The disadvantage of this device is the content of small metal parts capable of corrosion in an acidic peat environment, which limits the scope of its application. Dynamic contacts of metal blades with stone inclusions in peat raw materials can lead to sparks, which is unacceptable for peat mining.

The technical result is the creation of a device that allows you to increase the efficiency, due to the use of material with a low coefficient of friction, which does not contaminate the blades with wet particles of peat raw materials.

The technical result is achieved by the fact that the blades are made flat and resilient from polypropylene fiber, each blade block is a combination of cutting and thrust-throwing blades oriented perpendicularly to each other, while the cutting blade is installed perpendicular to the rotor axis and adjoins the front surface of the thrust-throwing blade on distance from its edge, which is equal to the value of the elastic bending deformation when capturing a portion of peat raw materials, and the capture-throwing blade are fixed on the hub radially parallel to the rotor shaft axis, and its length is greater than the length of the cutting blade by the amount of elastic bending deformation when capturing a portion of peat raw materials ...

The device is illustrated by the following figures:

fig. 1 - general diagram of the device;

fig. 2 - side view of the device, where:

1 - shaft;

2 - rear disc;

3 - hub;

4 - a block of blades;

5 - cutting blade;

6 - exciting-throwing blade.

The device consists of a rotor mounted on a shaft 1 (Fig. 2) (not shown in Fig.) Of a rear disc 2 (Fig. 1, 2) with a hub 3 (Fig. 2) and radial blocks 4 fixed on it (Fig. 1) cutting blades 5. The block of blades 4 consists of cutting blades 5 perpendicularly oriented to each other and capture-throwing blades 6 (Fig. 2). The cutting blades 5 are fixed on the hub 3 perpendicular to the axis of the rotor shaft 1 radially in front of the capture-throwing blade 6, which is located on the hub 3 parallel to the axis of the shaft 1. The cutting blade 5 adjoins the front surface of the catching-throwing blade 6 at a distance from its edge equal to the value elastic deformation of bending when capturing a portion of peat raw materials. The grasping-throwing blade 6 is rigidly fixed on the hub 3 radially parallel to the axis of the rotor shaft 1, and its length is greater than the length of the cutting blade 5 by the amount of elastic bending deformation when capturing a portion of peat raw materials (Fig. 2). The maximum bending deformation of the capture-throwing blade 6 is determined for the conditions of capturing a portion of peat raw materials from a roll with a bulk density of the material of 500 kg / m ³ . The rotary thrower contains a cylindrical body (not shown) along the axis of which a driven rotary thrower is installed. The grasping-throwing and cutting blades are made of flat and resilient polypropylene fiber, which has a low coefficient of friction.

The device works as follows. The device is mounted on the drive shaft 1 (Fig. 2) of the mounted machine (not shown in the Fig.), Located frontally on the traction-drive unit (not shown in the Fig.). The machine moves with forward speed along the roll of peat raw materials of triangular cross-section. When the rotor rotates (not shown in the figure), the axis of which is parallel to the roll, a portion of the material of a certain length is cut off from the cutting blade 5 of the rotor (not shown in the figure), equal to the feed amount to one block of blades 4 (Fig. 2). - throwing blades 6 capture the cut off portion of the material, which is concentrated in the pocket between the block of blades 4 and the rear disc 2, transport the material to the unloading window of the rotor casing (not shown in the figure) and throw it towards the stack.

With the help of a device for picking up and throwing peat raw materials, peat raw materials are concentrated in a pocket in the form of a pyramidal throwing body with a parabolic triangle section. And also, peat raw materials easily come off the surfaces of the blades with a low coefficient of friction along the blades and without adhesion to the material of the blades, which is facilitated by the properties of polypropylene as a material of the blades. This leads to the fact that the surface of the blades is not contaminated with wet particles of peat raw materials. The use of the proposed technical solution will increase the productivity of the device for picking up and throwing peat raw materials.
