Abstract

The utility model discloses a tail coal loader of a combined mechanization mining face conveyor. The technical scheme is that the coal loader comprises a vertical steel plate rack, wherein shaft seats are arranged on the upper edge and the lower edge of the steel plate rack, a vertical upright shaft is arranged on each shaft seat, a gear is arranged on an upper shaft head of each upright shaft, racks meshed with the gear are arranged on the steel plate rack, a rack hydraulic cylinder is connected between the racks and the steel plate rack, a chassis is connected with the upper part of a lower shaft seat of each upright shaft in a positioning manner, a hydraulic loader is hinged with the chassis, and a control valve bank of the hydraulic loader is arranged on the steel plate rack. The operation of the hydraulic valve bank can make the hydraulic loader dig up the scatteredly accumulated float coals around the ground with a bucket and load to the conveyer to export. By using the tail coal loader to clean up the scatteredly accumulated float coals in a tunnel before the tail of the colliery underground combined mechanization mining face conveyor, the manpower is saved, the working efficiency is high, the labor intensity is small, the performance is safe, and the cleaning is timely.

Description

Fully-mechanized mining working transporter tail slicer-loader

Technical field

The utility model relates to the supporting loading attachment of using of fully-mechanized mining working transporter under a kind of coal mine, fully-mechanized mining working transporter tail coaling gear under particularly a kind of coal mine.

Background technology

Under coal mine in the fully-mechanized mining working manufacturing process, coal-winning machine is when transporter tail coal cutting operation, the coal of the coal that cylinder throws away and coal group slabbing all is scattered and is stacked on the ground in the preceding tunnel of tail, especially in the underhand stopes, the float coal of this accumulation of being scattered on the ground is even more serious, the float coal piled up of being scattered in the preceding tunnel of tail is more, when fully-mechanized mining working advances, cause resistance increase when pushing away tail, the float coal of piling up that is scattered between step pitch makes fully-mechanized mining working can not reach the passing step pitch, thereby influence normally carrying out of next working cycles, influence is mined and is produced, so piling up float coal, being scattered in the preceding tunnel of tail should in time clear up, exactly the accumulation float coal that is scattered is installed on the transporter in time and transport, rely on coal mining machine roller self small part can only be scattered to pile up float coal to install on the transporter, float coal are piled up in most being scattered needs cleaning in time.In the prior art, the major part cleaning of piling up float coal of being scattered is to rely on the method for manually scooping up with spade that coal is installed on the transporter, cleaning is scattered and is piled up the float coal waste of manpower like this, inefficiency, labour intensity are also very big, in addition, tail is in region of stress concentration, and personnel are long working before tail, very easily the broken coal of being helped slabbing and top board to fall down by coal is injured, and is unfavorable for operating personnel's safety.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind ofly to save that manpower, high efficiency, labour intensity are little, job safety, the float coal that can in time pile up being scattered in the preceding tunnel of fully-mechanized mining working transporter tail under the coal mine install to the fully-mechanized mining working transporter tail slicer-loader on the transporter.

The utility model is realized with the following method.

Fully-mechanized mining working transporter tail slicer-loader has the steel plate frame vertical with horizontal plane, on the bottom and upper segment of steel plate frame has respectively, following axle bed, on, between the following axle bed vertical shaft vertical with horizontal plane arranged, the last spindle nose of vertical shaft has gear, horizontal slideway is arranged on the steel plate frame, the tooth bar that is meshed with gear is arranged on the horizontal slideway, be connected with the tooth bar hydraulic cylinder between tooth bar and the steel plate frame, the location is connected with the chassis above the following axle bed of vertical shaft, be hinged with hydraulic loader on the chassis, hydraulic loader has the lower end to be hinged on principal arm on the chassis, be hinged with the principal arm hydraulic cylinder between principal arm and the vertical shaft, the upper end of principal arm has the inner end to be hinged on the auxilliary arm of principal arm upper end, be hinged with auxilliary arm hydraulic cylinder between principal arm and the auxilliary arm, the outer end of auxilliary arm is hinged with shovel bucket, is hinged with the scraper bowl hydraulic cylinder between shovel bucket and the auxilliary arm, and the control valve group of above-mentioned hydraulic cylinder is arranged on the steel plate frame.

During use, steel plate frame of the present utility model can be fixedly attached to the front of transporter tail shell.Handle the tooth bar hydraulic cylinder and can promote the rotation of tooth bar slip driving vertical shaft, the vertical shaft rotation can drive the hydraulic loader rotation on the chassis, handling the principal arm hydraulic cylinder can make the lower end be hinged on the principal arm upper and lower swing in upper end on the chassis, handling auxilliary arm hydraulic cylinder can make the inner end be hinged on the auxilliary arm of principal arm upper end and the variable angle between the principal arm, handle telescopic hydraulic cylinder and can make the telescopic arm that is enclosed within auxilliary arm front end flexible, handle the scraper bowl hydraulic cylinder and can make the front of the shovel bucket that is hinged on the telescopic arm outer end along lifting.

Handle above-mentioned hydraulic cylinder of the present utility model, the float coal that hydraulic loader is piled up being scattered on the ground around the utility model has dug on the transporter of packing into scraper bowl to be transported.When being scattered the float coal of piling up in the preceding tunnel of fully-mechanized mining working transporter tail under the utility model cleaning coal mine, save that manpower, high efficiency, labour intensity are little, job safety, cleaning be timely.

Below in conjunction with accompanying drawing, the utility model is further described.
