[0020] like Figure 1-5 The concrete processing material conveying system shown includes a feed hopper 1, a belt scale 2, a discharge hopper 3 and a belt conveyor 4.
[0021] The feed hopper 1 is arranged above the front end of the belt scale 2. The front side of the discharge part 1A at the bottom of the feed hopper 1 is tilted backward to reduce the impact of falling materials and avoid affecting the measurement accuracy. A feed part 1B is provided on the top of the discharge part 1A, and the feed part 1B is connected to the discharge part 1A through a flange. The discharge part 1A is installed on the support frame 5, and the bottom of the support frame 5 is detachably installed on the belt scale bracket 6. It has a simple structure, convenient connection, and convenient inspection and maintenance. The bottom of the discharge part 1A is tilted upward from front to back to facilitate discharge. A discharge height adjustment component is provided on the rear side of the discharge part 1A, so that the discharge height can be easily adjusted.
[0022] The discharge height adjustment assembly includes a mounting frame 7, an adjustment plate 8, and a screw 9 and a sleeve 10 connected by threads. The mounting frame 7 is fixedly connected to the rear side of the discharge part 1A. The two sides of the adjustment plate 8 are plugged into the two sides of the mounting frame 7. The upper end of the adjustment plate 8 has a transverse bending edge. The lower end of the screw 9 vertically passes through the transverse bending edge and is connected to the mounting frame 7. The upper end of the sleeve 10 is connected to a rotating handle 11. The sleeve 10 is sleeved with a bearing 12 (the bearing structure is the existing technology, so it is simplified in the attached drawings). The inner ring of the bearing 12 is fixedly connected to the sleeve 10, and the outer ring of the bearing 12 is fixedly connected to the connecting plate 13. In order to prevent rotation wear, there is a gap between the bottom of the bearing 12 and the connecting plate 13, and between the top of the bearing and the lower surface of the rotating handle 11.

Thus, the material is transported to the bottom of the weighing sensor through the conveyor belt, and then the sensor system will perform real-time measurements according to the weight changes of the material and transmit the data to the control system. The control system adjusts the speed of the conveyor belt based on these data to achieve accurate control of the material weight. The conveyor belt of the belt scale 2 is provided with a material blocking boss 2D on both sides to prevent the material from slipping and affecting the measurement accuracy. The transverse shift assembly includes a threaded screw 16 and a connecting nut 17, the connecting nut 17 is fixedly connected to the slider 18, the end of the slider 18 is connected to the bearing 12 seat of the driven roller, and the slider 18 is slidably connected to the belt scale bracket 6, with a simple structure and convenient adjustment.
