[0025] like Figure 2As shown, the linkage assembly includes a linkage belt 91 arranged on the front and rear sides of the support frame 5, and the internal transmission sleeve of the linkage belt 91 is connected with two upper and lower transmission pulleys 92, one of which is connected to the two ends of the transmission roller 2, and the other is connected to the two ends of the transmission rod 934; due to the arrangement of the linkage belt 91 and the transmission pulley 92, the cleaning roller 932 can be adapted to the movement direction of the conveyor belt 1, thereby ensuring that the rotation directions between the facing surfaces of the two are opposite, and then the cleaning scraper 933 on the surface of the cleaning roller 932 can well scrape the material on the surface of the conveyor belt 1.

[0026] like Figure 3 and Figure 4 As shown, the cleaning blade 933 includes a rubber component fixedly connected to the surface of the cleaning roller 932, and a metal scraper is connected to the outer side of the rubber component away from the cleaning blade 933; due to the setting of the rubber component, it can be ensured that the cleaning blade 933 can be tightly abutted against the conveyor belt 1, and the extrusion resistance to the conveyor belt 1 can be greatly reduced.

[0028] like Figure 1 As shown, a connecting frame 6 is fixedly connected between the two support frames 5, the metering device 3 is fixedly installed on the connecting frame 6, the weighing roller 4 is movably installed inside the metering device 3, and the top of the metering device 3 is in rolling contact with the top of the inner cavity of the conveyor belt 1.

[0029] like Figure 1 As shown, an adjusting assembly 8 located below the metering device 3 is disposed inside the connecting frame 6 , and a tensioning assembly 7 is connected to the bottom of the adjusting assembly 8 , and the bottom of the tensioning assembly 7 contacts the bottom of the inner cavity of the conveyor belt 1 .

[0031] like Figure 2As shown, the tensioning assembly 7 includes two front and rear limit frames 71 fixedly installed at the bottom of the connecting frame 6, and a tensioning roller 72 is slidably sleeved between the two limit frames 71, and the bottom of the tensioning roller 72 is in rolling contact with the conveyor belt 1; both ends of the tensioning roller 72 pass through the limit frames 71 and are movably sleeved with left and right linkage rods 73, and the upper ends of the left and right linkage rods 73 are movably hinged to the ends of the linkage frames 81; due to the setting of the tensioning assembly 7, the movement of the tensioning assembly 7 can be controlled by the adjustment assembly 8, and then the tensioning roller 72 can be slowly moved downward under the limited support of the connecting frame 6, so that the conveyor belt 1 is tensioned with the cooperation of the left and right driving rollers 2.

[0032] The working principle and use process of this utility model:

[0033] Rotate any one of the cleaning and dust collecting components 93 to drive the two linkage belts 91 to approach each other through the driving pulley 92, and then push the tensioning roller 72 downward through the linkage rod 73 under the restriction of the limit frame 71, so that the conveyor belt 1 can be tensioned with the cooperation of the left and right driving rollers 2;

[0034] Then turn on the equipment and pour the material to be transported and measured onto the conveyor belt 1, so that it can be moved to the top of the weighing roller 4 under the conveyance of the conveyor belt 1, and then the weighing roller 4 is pressed and its weight is measured through the support frame 5;

[0035] The continuous operation of the conveyor belt 1 ensures that the two transmission rollers 2 rotate continuously, and then the cleaning and dust collecting assembly 93 moves continuously with the conveyor belt 1 under the cooperation of the linkage belt 91 and the two transmission pulleys 92;

Due to the cooperation of the cleaning scraper 933 and the inclined dust collecting cover 931, the fallen materials can slide to the predetermined area for collection and reuse.
