The invention relates to loading and unloading machines, namely to a continuous loader, and can be used for loading coal onto a scraper drift conveyor.

Known loader, which includes a working body, conveyor and tracked undercarriage And.

The most closest in technical essence to the present invention is a coal loader, including a plug that is tirped on the frame of a feeder with an eagru pack of laptsli and a scraper conveyor ;; a running gear with a drive containing a gearbox with an output shaft and a control panel 2j.

A disadvantage of the known loader is their limited maneuverability due to its large size and weight.

The purpose of the invention is to improve maneuverability in the production of small sections by reducing the size and weight, improving operating and maintenance conditions.

The goal is achieved by the fact that in the coal loader, including a feeder mounted on the frame with grabbing legs and a scraper conveyor, a running mechanism with a drive, including a gearbox with an output shaft and a control panel, the running gear is made of a support with guide wheels, of a running trolley, rigidly associated with the i-tail part of the frame and installed in the direction of the xxi support with the possibility of longitudinal movement, from the front support jack with rollers and from the rear lifting jacks, the drive with the gearbox and remote control laziness mounted on the running cart, wherein the support has a running chain of a gear unit output shaft sprocket mounted to cooperate with a running chain.

In this case, a feeder with grabbing legs is installed with the possibility of a gate relative to the frame in the horizontal and vertical planes by means of a drive.

The loader includes a support 1 of the scraping conveyor, a undercarriage 2 supporting rollers 3, longitudinally; guiding grooves 4, upper and lower bottoms of the undercarriage 5, idle and cargo branch b.

reloading chain, hinge 7 connecting the undercarriage with a retractable frame, retractable frame 8, guiding gussets 9 front supporting jack 10, rollers 11, section 12 horizontal turns, hinge 13 horizontal turns of the section with a feeder ,, jack 14 turning sections , steel plates 15 sliding frame connections in the section of horizontal and horizontal turns, hinge 16 vertical turns of the feeder, jack 17 vertical} tical turns of the feeder, feeder 18, scooping legs 19, drive sleeve 20, vertical shaft 21

Sprocket 35, running chain 36, lifting jacks 37, eyelet 38 with bearing pin, knobs 39 for turning on jacks 37, mas5 lonpump 40, oil tank 41, panning 42 scraper conveyor 43, connecting hooks 44 slats, brooks 45 including jacks 45. The loader works as follows.

When loading coal, when driving drifts from the output shaft before the slab otpalki, the loading device is winched 31

5 support 1 back to the stop. The sock of the feeder 18 by the jack 17 is lowered onto the ground, the engine 22 is turned off, the propeller shaft 25 with grabbing legs 19 19 ratchet engagement 24

Q is disconnected from drive coupling 20 -. Also, with the handle 30, the drive sprocket 29- with the overload circuit 6 is freed from the working forces. Turning off knots from working forces is necessary to reduce explosive impacts on knots of the machine. After ottalka zabo, the engine turns 22 on; blowing sprocket 29 with overload circuit b. After a partial overload of coal from the feeder 18 by the reloading chain b on the cargo chute to the scraper conveyor 43 with ratchet engagement 24 on the leading coupling 20. the propeller shaft 25 is turned on with scooping paws 19. As the winch turns 31 by handle

forward travel 32, the loading device extends to full length up to ynopS. Then the propeller shaft 25 with zagrebayuschimi paws 19, as well as the leading va-star 29 with the overload circuit b is disconnected from the work force, jack 17 raise the toe of the feeder 18, the winch 31 takes the loading device off towards the stop. The sock of the feeder 18 with the jack 17 is lowered onto the ground, the section of the horizontal turns 12 with the feeder 18 of the jack 14 is turned to the production borg, where there is still unloaded coal.

Next, the handle 30 includes a drive clutch 20 with a drive shaft, an asterisk 29 and with an oversize chain 6, ratchet meshes 24 include a propeller shaft 25 with grabbing legs 19.and plunging the coal. advance The loading device is winched 31 forward. After this section of the horizontal turns 12 with a feeder 18 jack 14 is installed in the longitudinal position. With a ratchet engagement 24, the drive shaft 25 with the paws 19 is turned off in the same way by the handle 30, the drive clutch 20 is turned off with the drive sprocket 20 and with the overload circuit 6.

If during this cycle the coal is completely removed from the bottom, the loading device is moved back to the stop using a winch 31, and the bottom is re-scooped. But if uncleared coal remains in the cob, the ratchet of the scraper conveyor 43 is increased. For this support 1, the connecting hooks 44 are disconnected from the scraper 42 of the scraper conveyor, the scraper chain of the conveyor 43 is disconnected. Then, the loading device is lifted with the support jack 10 with the rollers 11 and the rear lifting jacks 37, while the support-1, which is in engagement by the longitudinal grooves 4 with the support rollers 3 of the undercarriage 2, also together with the loading device is raised above the ground.

By turning on the reverse of the winch 31, the vertical sprocket sprocket 35 which is engaged with the running chain 36 rotates, the MR tooth longitudinally moves the running chain 36, and the scraper conveyor 1 moves along with the chain. Moving the support 1 forward until it stops with a front support jack 10 with rollers 11 and rear lifting jacks 37, the loading device together with the support 1 is lowered onto the ground. In the space formed between the support 1 and the pitching stage 42 of the scraper conveyor 43, the grates are inserted and fastened with connecting hooks 44. The scraper chain of the conveyor 43 extends and joins. The next cycle of work is then completed.

Before transporting the loader, the sock of the feeder 18 is raised by the jack 17 to the top, the support 1 is disconnected from the grate-scraper conveyor 43. By turning on the winch 31, the forward handle 32 extends

5 loading device forward until it stops, Next, supporting the jack 10 with rollers 11 and lifting jacks 37 loading device with a support 1 is raised above the ground.

By turning on the winch 31, the handle of the rear stroke 32 moves the support 1 forward until it stops. Next, the support jack 10 with the rollers 11 and the lifting jacks 37, the loading device with the support 1 is lowered and mounted on the ground, after which the cycle is repeated.

When being transported under its own power in the reverse, rearward direction, the nodes are switched on in the reverse order.

In case of horizontal Turns, it is necessary to deploy the magic and set it in the direction of development.
