Description
Technical Field
The utility model relates to an end formula of unloading is scraped trigger and is reprinted quick-witted connecting device.
Background
The underground fully mechanized caving face of the coal mine is provided with equipment such as a hydraulic support, front and rear scraper conveyors and the like, the hydraulic support and the front scraper conveyor are mutually supported and interacted, and the hydraulic support and the front scraper conveyor are jointly propelled forwards along with the mining of the face. The rear scraper conveyer is connected with the hydraulic support through the round-link chain, and when the working face is pushed forward by one step, the hydraulic support pulls the rear scraper conveyer through the round-link chain to push forward by one step. The reversed loader and the end supports arranged on the two sides of the machine body are mutually pivoted to move forwards. The transfer conveyor is generally moved after the front and rear flight conveyors and the face support have been moved. The front scraper conveyer and the rear scraper conveyer convey materials such as coal, gangue and the like mined by the coal mining machine from the tail to the nose of the scraper conveyer, then the materials are unloaded from the nose of the scraper conveyer to the unloading port of the reversed loader, then the materials are unloaded to the reversed loader, and then the materials are conveyed to the belt conveyor by the reversed loader in the next step.
The conveyor and the reversed loader respectively move forward, the conveyor is in front, the reversed loader is behind, two-step operation is carried out, time consumption is long, and efficiency is low. The conveyer and the reversed loader are overlapped, and materials such as coal, gangue and the like on the conveyer are unloaded onto the reversed loader, so that the conveyer and the reversed loader are asynchronous in movement, relative displacement can be caused between the conveyer and the reversed loader, and the condition that the scraper machine head and the unloading port of the reversed loader are in the optimal unloading state cannot be guaranteed. The patent CN 103362545A-scraper conveyor and self-moving type reversed loader linkage pushing and pulling frame device and the patent CN 204299616U-coal mine fully mechanized mining face synchronous moving transportation equipment also have mechanisms for connecting the reversed loader and the conveyor, but are fixedly connected without relative displacement. However, the scraper and the reversed loader are respectively driven by respective driving mechanisms, and the respective driving mechanisms are necessarily asynchronous to cause deviation, and after the scraper and the reversed loader are fixed together, the asynchronous causes that the fixed connecting mechanism between the scraper and the reversed loader is stressed too much, so that the scraper and the reversed loader are easy to break.

Detailed Description
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that "connected" and words used in this application to express "connected," such as "connected," "connected," and the like, include both direct connection of one element to another element and connection of one element to another element through another element.
As shown in fig. 1-5, the connecting device of the end-discharge type scraper and the reversed loader comprises a push plate 3 fixedly connected with the reversed loader 1 and a connecting piece 4 fixedly connected with the scraper 2; the connecting piece 4 is rotatably arranged on the pushing plate 3, and a limiting device for limiting the rotating angle of the connecting piece around the pushing plate is arranged between the connecting piece 4 and the pushing plate 3. Therefore, the connecting piece 4 and the pushing plate 3 can rotate at a certain angle, and certain displacement and angle deviation can be allowed between the reversed loader 1 and the scraper conveyor 2 which are connected with the connecting piece, so that the connecting piece and the scraper conveyor can move together to ensure the coal unloading effect smoothly in a lap joint manner, and parts can be prevented from being damaged by hard connection.
One end of the connecting piece 4 is hinged with the pushing plate 3, the limiting device is a limiting plate 5, and the limiting plate 5 is arranged on the pushing plate 3 or the connecting piece 4 to block the rotating angle between the connecting piece 4 and the pushing plate 3. The other end of the connecting piece 4 is fixed with the scraper conveyor 2, the other end of the connecting piece 4 can be provided with two through holes 6, the corresponding positions of the scraper conveyor 2 are also provided with through holes, and the connecting piece 4 is connected with the scraper conveyor 2 through a pin shaft 7.
