Description

The invention relates to mine transport, loading machines having a continuous loading organ in the form of paired picking feet * and can be used in these loading machines in underground conditions, in open cast mining, in warehouses of bulk and lumpy materials in ports, transshipment bases, etc. P.

There are known continuous loading organs ^ consisting of a receiving table, conveyor, raking legs (11

The disadvantage of the device is a small front loading.

The increase of the front of the loading is carried out through the use of additional raking legs, which are driven from the main raking legs through a system of levers.

The closest in technical essence to the proposed one is a loading organ, including a receiving table, conveyor, main and additional heeling legs. The drive of the main heating paws is carried out through the crank disks, and the additional ones through the articulated sliding pull rods. The loading front of the additional raking legs is changed by adjusting the length of the sliding rods, which are located on top of the raking legs G 2].

In a well-known loading organ, the loading front is widened by using additional cutting legs connected with crank disks, adjustable by sliding rods. Additional heel paws are set so as to feed material into the path area of the main heel paws. The presence of a lever system does not allow the implementation of the loading organ to a depth exceeding _{20 the} length of the stroke, since the extension. traction rods are located on top of the heeling paws and form a rigid triangle with the discs. Material that has fallen inside this triangle cannot be loaded onto the conveyor and is inside the triangle for a long time, creating an additional load on the drive mechanism.

The invention is of uproie- ₅ 'structure of the loading organ.

This goal is achieved by the fact that the loading organ has a continuous operation, including a receiving table, on which internal and external lifting legs are mounted and a conveyor placed between them, the receiving table is equipped with guides with brackets, in the upper part of which the lifting legs are mounted ₁₅ NOSTA possible with simultaneous reciprocating motion perpendicularly to the conveyor axis by power cylinders. two-way operation, while the hydraulic cylinder rods with free ends _{2β are} pivotally connected to the brackets of the external raking legs, and the middle part, by means of a rack-and-pinion gear, is connected to the brackets of the inner raiser LI · jjj

In addition, the raking legs are made in the form of straight arms having a wedge shape in cross section. ! In this case, the guides may have a trolley mounted under the receiving table on which gear racks of the rack and pinion gear are rigidly fixed.

In FIG. 1 shows a continuous loading organ; in FIG. 2 - external heeling paw, longitudinal section along the axis; in FIG. 3 - inner ^3S raking foot and the axis of the synchronizer gear, section along the axis.

The continuous loading organ includes a receiving stand 1, a conveyor 2, external 3 and internal 4 raking ⁴⁰ feet mounted on brackets 5 and 6, moving in guides 7 and 8 of the receiving table. The rods 9 of the hydraulic cylinder 10 are pivotally connected to the levers 11, at the ends of which * 5 brackets 5 of the external raking legs are fixed. On the rods 9 are fixedly mounted leading gear racks 12, which through gears 13 are connected to the driven gear racks 14, mounted on 50 rods 15 connecting the brackets 6 of the inner heats.

The rod 15 together with the driven gear racks 14 and the guides 16 form a trolley 17, which is mixed along the rollers 18, mounted under an inclined plate.

The continuous loading organ operates as follows.

In the process of introducing the loading body into the stack, the external heaving lavas 3 under the action of the traction force of the hydraulic cylinder 10 are translationally moving. At the same time, one paw moves towards the conveyor 2 and with its vertical side shifts a portion of the material to the region of operation of the inner heap paw 4. Through the rack-and-pinion type synchronizer, the force from the hydraulic cylinder 10 is transmitted through the gear wheel and the driven gear rack to the internal raking foot 4, which then moves from the conveyor 2 towards the outer raking foot 3. Due to the wedge-shaped cross section of the foot, the material flows. through the inner heel paw 4 towards the conveyor 2. Thus, the inner and outer heap paws move towards each other. Another pair of heels at this time moves in opposite directions. Moreover, the outer raking foot 3 moves from the conveyor 2, and the inner 4 toward the conveyor, moving its vertical side to the conveyor 2. Having reached the extreme points, the hydraulic cylinder 10 reverses the direction of movement of the raking legs. The cycle of work is repeated.

A continuous loading organ allows you to place the drive mechanisms and change the loading front under the receiving plate, adjust the loading front by changing the length of the hydraulic cylinder rod, and generally simplify the configuration due to the exclusion of the engine, gearboxes, crank disks, bearing assemblies and couplings from it.

Claims (3)

loaded onto the conveyor and for a long time inside the triangle, creating an additional load on the drive mechanism. The aim of the invention is to simplify the design of the loading body. The goal is achieved by the fact that the loading body has a continuous action, including a receiving table, on which internal and external scoring feet are mounted and placed between HnNffl in the neck, the receiving table has guides with kroschiteyny, in the upper part of which are fixed on the rowing feet, installed with the possibility of synchronous reciprocating motion perpendicular to the axis of the conveyor by means of a two-way power cylinder, with the hydraulic cylinder rods with free ends hinged s with external brackets shovel paws, and the middle portion by rack-and-gear - with brackets The inner shovel Moreover, shovel legs are in the form of straight lever having a cross-sectional wedge shape. In this case, the guides may have a cart mounted under the receiving table, on which the rack and gear racks are rigidly fixed. In FIG. 1 shows a continuous loading body; in fig. 2 - external paw, longitudinal section along the axis; in fig. 3 - internal paw and the axis of the synchronizer gear, section along the axis. The loading body of continuous action includes a reception table 1, conveyor 2, outer 3 and inner 4 piles, mounted on brackets 5 and 6, moving in directions 7 and 8 of the receiving table. The rods 9 of the hydrodrome indra 10 are hingedly connected to the levers 11, on the ends of which the brackets of 5 external scooping paws are fastened. On the rods 9, the leading gear racks 12 are fixedly fixed, which, through the gears 13, are connected with the driven gear racks 14 fixed on the thrusts 15 connecting the brackets 6 to the inner scooping legs. The Tscra 15, together with the driven toothed racks 14 and the guides 16, form the carriage 17, which is agitated along the rollers 18 fixed under the inclined plate. The continuous loading body operates as follows. In the process of inserting the loading body into the stack, the external raking legs 3 under the action of the thrust force of the hydraulic cylinder 10 are progressively mixed. In this case, the paw moves in the direction of the conveyor 2 and with its vertical side shifts to the area of operation of the internal scooping paw 4 oiord of material. Through a synchronized rack-and-pinion type force from hydraulic cylinder U, the leading gear racks 12 are transmitted through the gear wheel and the driven gear rack to the internal heating paw 4, which at the same time moves from the conveyor 2 towards the external heating paw 3. Due to the wedge-shaped cross-section of the paw, the material flows. through the inner paw 4 towards the conveyor 2. Thus, the inner and outer paws move towards each other. Another pair of scoring paws at this time is moving in opposite directions. Moreover, the external paw 3 moves from the conveyor 2, and the internal 4-3 side of the conveyor, moving the material to the conveyor 2 with its vertical side. When it reaches the extreme points, the hydraulic cylinder 10 reverses the direction of movement of the paws. The cycle of operation is repeated. The continuous loading body allows the drive mechanisms and changing the loading front to be placed under the receiving plate, adjusting the loading front by changing the length of the hydraulic cylinder rod, and generally simplify the configuration due to the exclusion of the engine, gearboxes, crank disks, bearing assemblies and couplings.
