The working principle of the invention is as follows:

the motor 5 is started by the aid of the external controller, an output shaft of the motor 5 drives the roller shafts 3 fixedly connected with the motor to rotate, the belt 4 which is connected to the surfaces of the three roller shafts 3 is transmitted by the rotating roller shafts 3 in a driving mode, the transmission track of the belt 4 is limited by the aid of the limiting mechanism, and therefore stability of the belt 4 in transmission is maintained;

when a certain height of the quantitative coal blocks is required to be conveyed, the weighed coal blocks are placed between two partition plates 6 on the horizontal conveying section of the belt 4 by means of external feeding equipment, along with the conveying of the belt 4, the coal blocks piled on the top of the belt 4 are flattened through a flattening mechanism, the piled height of the coal blocks is shortened, the excessive inclined upward conveying of the piled coal blocks is avoided, the partition plates 6 are turned over in a sliding manner, along with the inclined upward conveying of the coal blocks by the belt 4, the arranged partition plates 6 are convenient to block the flattened coal blocks when the inclined upward conveying of the coal blocks is carried out, and the coal blocks are prevented from directly sliding down along the surface of the belt 4, so that the conveying of the coal blocks is prevented from being influenced;

in the process of obliquely upward transmission of the partition plate 6, the first rotating shaft 8 connected with the drainage plate 10 is driven to rotate by virtue of the first guide rail 9 and the turnover mechanism, so that the drainage plate 10 is driven to outwards turnover and extend from the mounting groove 7, and coal blocks on the belt 4 are pushed to the middle by virtue of the drainage plate 10 which is symmetrically turnover and extend on the side wall of the partition plate 6 and the assistance of the telescopic scraping mechanism, so that the coal blocks slide along the surface of the drainage plate 10 towards the middle of the belt 4, the reduction of the extrusion of the coal blocks to the side wall of the mounting plate 2 due to the downward sliding of the coal blocks in the obliquely upward transmission process is facilitated, meanwhile, the coal blocks in the middle are pushed, and the coal blocks are conveniently and intensively discharged in the later stage.
