Description

The invention relates to the development ^of non-metallic deposits in the building materials industry, in particular to devices for chiseling stone and low-access stone-cutting machines used mainly for the extraction of stone from limestone.

A device for the selection of stone, including a collecting tray and a conveyor [Ts. . .

A disadvantage of the known device is low productivity due to the fact that as the mass of waste increases, the mass flow increases to the sides of the tray, friction increases, the mass flow stops due to the blockage of the tray, the machine has to be stopped and the tray is manually cleaned.

Closest to the proposed device includes a tray with sides and a bottom M2

A disadvantage of the known device is low productivity due to the large resistance to movement of the stone in the tray.

The purpose of the invention is to increase productivity by reducing the resistance to movement of the stone? On the tray.

This goal is achieved by the fact that in the device for the selection of stone, including a tray with sides and bottom and feed mechanism, the latter is placed in the bottom and is made in the form of two crankshafts and mounted on them with the possibility of plane-parallel movement in different phases, parallel rails, and sides installed with the possibility of plane-parallel movement in a plane perpendicular to the parallel rails, by means of a drive.

The drawing shows a device for the selection of stone.

The device includes a tray with a bottom 1 in which parallel rails 2 are mounted on two crankshafts 3 · At the ends of the shafts 3 there are gears 4 which engage with gear 5 ″ mounted on the shaft 6, on the end of which there is an asterisk connected by a chain with an asterisk 8 mounted on the output shaft 9 of the gearbox 10. On both sides of the bottom 1 there are four pairs of bearings

11. The bearings have shafts 12 with eccentrics 13, placed in bearings 14, which are rigidly connected to the sides 15 · The upper ends of the shafts are equipped with gear wheels 16 which engage with gears 17. Gears 17 are mounted on shafts 18 and 19, on which are fixed sprockets 20. The shaft 19 is provided with a bevel gear 21, which is engaged with the bevel gear 22 mounted on the output shaft of the gearbox 10.

The device works as follows.

Installed on the saw carriage stone-cutting machine device along with it is moved forward, hooking the bottom of the tray 1 otpilennyy.ryad Cams ^w it. Having traversed the bottom of the tray, the stones come into contact with the slats 2, which, under the pressure of the drive, move the stone Chna themselves. and pull up stones for

account of contact with their side surfaces, helping the lower rails. Under

the interaction of the lower rails and sides

stones move to the rear cut

5 bottoms 1 and get on the conveyor. Synchronous traction on the lower and lateral surfaces of the stone significantly improves the process of selection of the stone.

10 The effectiveness of the proposed device is to reduce the resistance to movement of the stone on the tray and save energy.

Claims (1)

Claim A device for collecting stone, including a tray with sides and bottom 20 and the feeder, which is based on the fact that, in order to increase productivity by reducing the resistance to movement of the stone on the tray, the feeder size 25 shchen in the bottom and made in the form of two crankshafts and mounted on them with the possibility of plane-parallel movement in different phases of parallel rails, and the bead 30 are installed with the possibility of plane-parallel movement in a plane perpendicular to the parallel rails, by means of a drive.
