Description

Movable reversed loader with impact resistance function Technical Field The invention relates to the technical field of reversed loaders, in particular to a movable reversed loader with an impact resistance function. Background The scraper transfer conveyor is used in a transportation roadway of a large fully-mechanized mining working face with high efficiency and high yield, and two ends of the scraper transfer conveyor are respectively connected with a conveyor of the working face and the tail of the belt conveyor so as to transfer coal conveyed by the scraper conveyor of the fully-mechanized mining working face onto the belt conveyor after rising from the bottom of the roadway. The utility model patent application of the patent application publication number CN213010228U discloses a novel scraper conveyor buffer device, the structure enhances the stability and safety of the scraper conveyor by adding a buffer device on a scraper conveyor head, the free falling distance between coal materials and a telescopic tail of a belt conveyor is shortened by guiding the buffer plates, so that the impact force of gravity on the telescopic tail of the belt conveyor during free falling is reduced, the plurality of buffer plates can enable the coal materials to fall in a dispersed manner, smaller coal materials fall firstly, larger coal materials fall later, and the impact force suffered by the telescopic tail of the belt conveyor is further dispersed. But this structure is when in actual use, because the chain drives the scraper blade in the elevating conveyor and carries the in-process of colliery to the scraper blade is continuous to contact with the colliery to produce relative effort between the colliery, thereby the peg of scraper blade connection is become flexible easily under long-time use, and the scraper blade also can produce and split the damage, thereby need often maintain the scraper blade, especially when maintaining in the internal passageway that installs the case lid on the fender coal board top, because the outside personnel can not observe and cause the potential safety hazard easily, consequently, the movable elevating conveyor with shock resistance function is proposed now. Disclosure of Invention In order to overcome the above-mentioned drawbacks of the prior art, the present invention provides a mobile reversed loader with impact resistance, so as to solve the above-mentioned problems in the prior art. In order to achieve the aim, the invention provides the following technical scheme that the living body has the shock resistance function The utility model provides a movable transfer conveyor, including the bottom plate, keep off the coal board, the roof, aircraft nose and buffer, install buffer on the aircraft nose, aircraft nose one end is connected with the bottom plate, keep off the coal board is all installed to the bottom plate both sides, two keep off the coal board top and support jointly and have the roof, the chain has been laid to the symmetry on the bottom plate, a plurality of scrapers are installed to the cooperation on two chains, two keep off the coal inboard and all install the slide rail, two slide rails and each scraper blade both ends sliding fit, two keep off the coal board on support and be provided with the driving, elevating system is installed to roof one end, elevating system is connected with the driving and cooperates. Through stopping the operation of elevating conveyor, then start the hydraulic pump, make the hydraulic stem stretch down, thereby make the gyro wheel follow the lifting groove gliding, the landing is to advancing in the inslot, through unscrewing each locking lever, sliding connection piece removes in the spout of connecting plate bottom, make lifting plate and link separation, then elevating system resets, the maintainer gets into on the automobile body, through pulling the handle, make the automobile body advance along advancing the groove, remove to scraper blade one side of required maintenance, change the scraper blade, through placing the backup pad in the chain bottom, make backup pad both ends and slide rail sliding fit, overlap two chains respectively on the standing groove, then press the clamp plate in the backup pad, the bolt is pegged graft in the constant head tank that corresponds, make two chains by the crimping between backup pad and clamp plate, be connected backup pad and clamp plate through the peg, can accomplish the change to the scraper blade, simultaneously, outside personnel error starts the elevating conveyor, the chain can move in the bottom of the car, make the maintainer not receive the chain removal to influence, thereby avoid producing the incident, the security that the maintainer overhauls is carried out. Preferably, the inner side of the coal baffle plate is provided with a travelling groove, one end of the travelling groove is provided with a lifting groove in parallel, and the coal baffle plate at the top end of each
