The top of the rocking plate 12 is rotatably connected with the bottom roller 13 through the bearing, and rolling friction is formed between the conveyor belt 3 and the bottom roller 13. The two bottom rollers 13 are close to each other and pressed against the bottom of the conveyor belt 3. The bottom of the bottom shell 1 is fixed with two fixed plates 14 located between the two rocking plates 12. A group of tension springs 15 are installed on the side away from each other of the two fixed plates 14. The number of each group of tension springs 15 can be selected according to actual conditions. The other ends of the two groups of tension springs 15 are fixedly set on one side of the bottom of the rocking plate 12. The elastic deformation of the tension springs 15 can make the tension springs 15 elastically tighten the bottom end of the rocking plate 12, and then the rocking plate 12 can drive the bottom roller 13 to swing. At this time, the bottom roller 13 can press the bottom of the conveyor belt 3, thereby making the loose conveyor belt 3 tight.

[0016] Specifically, the driving assembly includes a conveying motor 6 and a reducer 7, which are both installed at one end of the side wall of the bottom shell 1, and the output end of the motor is connected to the output end of the reducer 7, and the output end of the reducer 7 is connected to one end of the inner shaft of one of the driving rollers 2. The conveying motor 6 can drive one of the driving rollers 2 to rotate through the reducer 7, and drive the conveyor belt 3 to rotate, so that the aggregate can move from the feeding end to the unloading end of the conveyor belt 3, and fall to the inside of the mixer at the slide 10 for mixing and stirring.

[0017] Specifically, the material guiding assembly includes a material guiding motor 8 and a gear roller 9. The material guiding motor 8 is installed on the outer wall of the discharge end of the hopper 4. The two inner shafts of the gear roller 9 are rotatably connected to the inner cavity of the discharge end of the hopper 4 through bearings. The output end of the material guiding motor 8 is fixedly connected to one of the inner shafts of the gear roller 9. The material guiding motor 8 can drive the gear shaft to rotate at a uniform speed under the operation, and drive the aggregate to fall evenly on the conveyor belt 3 under the rotation of the gear shaft.

[0018] Specifically, a slide plate 10 is fixedly provided on one side of the discharge end of the bottom shell 1, and the upper surface of the slide plate 10 is inclined downward to form a slope design. The design of the slide plate 10 allows the aggregate to fall directly into the mixer by its own gravity.

[0019] Specifically, the side wall height of the bottom shell 1 is higher than the height of the material being conveyed on the top of the conveyor belt 3 , and its design purpose is to protect the transportation of aggregates and prevent the aggregates from sliding on the conveyor belt 3 .

When the conveyor belt 3 rotates, the elastic deformation of the tension spring 15 is used to make the tension spring 15 elastically tighten the bottom end of the rocking plate 12, and then the rocking plate 12 can drive the bottom roller 13 to swing, and then the bottom roller 13 can press the bottom of the conveyor belt 3, so that the loose conveyor belt 3 becomes tight, thereby avoiding the problem that the aggregate cannot move due to the loose conveyor belt 3.
