Abstract

The invention relates to mining, namely, devices for loading bulk materials from a stack previously poured by other machines, and improves reliability by reducing the loads on the buckets. The device for loading bulk materials contains a self-propelled gantry 1 carrying a bucket tool 9 mounted on self-propelled trolleys 4 with a drive relative to the horizontal axis, equipped with pins 27 installed along its length between the buckets 18 and protrusion , ryliteli made rotatable and equipped with symmetrically located cutting edges. In the process, the coarse fractions of the cargo are crushed by the rippers and taken away by the buckets. 1 hp f-ly, 3 ill.

The invention relates to mining, namely, devices for loading bulk materials from a stack previously poured by other mechanisms.

The purpose of the invention is to increase reliability by varying the loads on the buckets.

FIG. 1 shows the device, front view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The device for loading bulk materials contains a portal 1, supports 2, 3 of which are mounted on self-propelled carriages 4, moving them along the track 5. In the inside of support 2, there are support rollers 6. Inside the hinge support 3, rollers 6 are mounted on frame 7, rigidly connected to the portal 1. On the rollers 6 a rotary actuator 8 is mounted about a horizontal axis tubular working body 9, which rests on rollers 6 with flanges 10. On the side of the support 2, the working body 9 is equipped with a pin gear 11, which is connected to a working actuator 8 of rotation his body. Inside the working body 9, internal semi-rings 13 are mounted on the frame 12, between which a receiving funnel 14 and a conveyor belt 15 are installed, at one end of which, a discharge funnel 17 is installed above the collecting conveyor 16. the windows communicate with the internal cavity of the working member. Extreme buckets are made with pick-ups 19, 20. Intake buckets 18 on the surface of the working body can be located along a helix or according to any other scheme. On the inside of the bucket plate 21, a hinge 23 is fixed on the hinges 22, which changes position depending on the direction of rotation, shown by arrows.

On the outer surface 24 of the working body 9 in order to eliminate wedging of pieces of material between the rear wall 25 of the intake buckets 18 and the slope of the stack 26, pins 27 are installed in which rotary rippers 28 reinforced with hard metal plates 29 are inserted. The rippers are rotated on the fingers 30 to the extreme positions depending on the direction of rotation of the tool body to avoid mashing the back plates when meeting with a piece of material. In this case, the rippers 28, with cutting edges, protrude beyond the path 31 of the buckets.

A device for loading bulk materials works as follows.

The drive 8 turns the working body 9 and the drive of self-propelled carts 4,

and along the track 5, the device is moved to the stack 26, which has been filled with the stacker. When moving forward, the working body 9 rotates, captures the bulk material with intake buckets 18, in which the flap 23 rotates on the hinge 22 under the pressure of the bulk material and forms a container for the bulk material between the walls of the bucket. With further rotation of the working body 9, the fixed semi-ring 13 prevents the granular material from pouring out from the bucket. When the bucket is above the receiving funnel 14, the bulk material is poured out of the bucket and falls onto a conveyor belt 15, which moves the bulk material inside the working body

and through the discharge funnel 17 pours it onto a collecting conveyor. When the device is moved back to ship the newly poured bead, the reversal of the filling organ is turned on, the device reverses and the device is unloaded. At the meeting of the working body of a large piece, rippers 28 come into contact, projecting beyond the envelope of the bucket edge. When this occurs, the inversion of the piece from the mass on the surface, after which it easily falls into the bucket. If it is deep in the mass and held by it, it is cut into separate, easily removable parts or crushed. This form of the actuator eliminates the hitting, crushing and crushing of pieces of the upper plate 21 of the bucket, and consequently, the likelihood of its failure is excluded.

Claims (2)
