Description

This invention relates to the sorting and grinding of lumpy rock.

Self-propelled units are known, consisting of a receiving hopper with a feeder-screen, a crusher, a vibrating screen, conveyors and a self-propelled carriage.

The purpose of the invention is to increase efficiency, reduce weight, dynamic loads during operation and metal consumption.

This is achieved by the fact that the frame of the unit consists of two trusses interconnected by an articulated hinge, with the feeder frame being a carrier, part of the supporting frame, and the sub-axle axis can be moved along hydraulic rails directed obliquely to the horizontal part of the frame, as a result, the heaviest part of the unit, the receiving hopper with the feeder-roar, is lowered by the supporting fifth onto the ground during operation.

FIG. I - the proposed installation in the working position; in fig. 2 - installation frame, top view; in fig. 3 - the same, side view (the flat lines - the working position, the silver ones - the transport position).

The support frame of the installation consists of two trusses — the main 1 and the auxiliary 2, interconnected by an articulated horizontal axis 3, and rests on three pneumowheels axes: the central axis 4 with pneumatic tires 5 is driven, providing movement of the unit, and the extreme ones are controlled (rotary ).

The sub-bunker axis 6 is movable, its movement is carried out with the help of hydraulic cylinders 7 along guides 8 located on the inclined part of the frame. From lateral displacement, axis 6 is supported by abutments 9 secured thereto (axis 6). and the pneumatic wheels 10 are brought together to the limit ensuring that they are placed under the bunker 11. On the cantilever of the inclined part of the main frame 1 there is a supporting plate 12, the installation of which rests on the bottom of the ground during operation. The auxiliary frame 2 rests on the axis 13 with controlled pneumatic wheels 14. On the main part of the frame there is a receiving bunker with a feeder-screen 15, a crusher 16, a control box 17 and a belt conveyor 18, which ensures the delivery of the rock mass from under the feeder-screen 15 to vibro-screen 19, located on the auxiliary frame 2. In addition to the vibrating screen 19, an assembly conveyor 20 is placed on the auxiliary frame 2, which ensures the delivery of material from under the crusher 16 and from the vibrating panel 19 to the reloading conveyor, and the installation of dust absorption cycle permanent type 21.

After the installation is moved to a new place of work, axis 6 with pneumatic tires 10 is displaced in the direction of its center along guides 8, and the frame of support heel 12 is lowered onto the ground. The axle is kept from lateral displacement by the stops 9 and during operation the installation carries no load, except for its own weight and the weight of the wheels. The raw material is loaded into the receiving bin 11 by an excavator or a loader. With the help of a grader 13, the fractions that cannot be crushed are separated, and the large material remaining on the feeder web is fed to the crusher 16. From the crusher, the material enters the assembly conveyor 20. The small fractions those separated by the feeder rumble come to the conveyor 17 and, via it, to the vibrating screen 19, where the waste is separated. Product with vibrating screen and

The crusher under the crusher conveyor 20 is sent for further processing.
