[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2As shown in Figure 3, this embodiment proposes an energy-saving and environmentally friendly concrete batching machine, including a batching bin 1, a feeding pipe 2, and an automatic weighing device 3. The bottom of the batching bin 1 is connected to the feeding pipe 2, and the automatic weighing device 3 is installed inside the feeding pipe 2. A sealing cover 4 is hinged to the bottom end of the feeding pipe 2. A drive mechanism is provided on one side of the batching bin 1, and a dispersing mechanism is provided inside the batching bin 1. The material is conveyed into the batching bin 1, and the dispersing mechanism will automatically disperse the material to pre-treat the material and avoid large particles from affecting the mixing efficiency. The crushed material is discharged downward through the feeding pipe 2, and the automatic weighing device 3 can monitor the weight of the material in real time. Then, the drive mechanism drives the sealing cover 4 to rotate up and down to close or open the sealing cover 4. The crushed material is directly conveyed into the mixing equipment by the conveyor belt, reducing material transfer links, reducing energy consumption, and playing an energy-saving role.

[0019] The dispersing mechanism includes a rotating shaft 5, rotating blades 6, a rotating motor 7, pulleys 8, and a belt 9. The rotating shaft 5 is symmetrically connected to both sides inside the mixing tank 1. Multiple rotating blades 6 are fixedly connected at equal intervals to the outer side of the rotating shaft 5. One end of the rotating shaft 5 extends through one side of the mixing tank 1 and is fixedly connected to a pulley 8. Two pulleys 8 are connected to each other via a belt 9. A rotating motor 7 is fixedly installed on one side of the mixing tank 1. The output end of the rotating motor 7 is fixedly connected to one end of one of the rotating shafts 5. The distance between adjacent rotating blades 6 is equal, and they are at a 30° angle. The rotating blades 6 on the two rotating shafts 5 are staggered. The output end of the rotating motor 7 can drive one of the rotating shafts 5 to rotate, which in turn drives the other rotating shaft 5 to rotate synchronously via the pulley 8 and belt 9. The two rotating shafts 5 drive the multiple rotating blades 6 on their outer sides to rotate together. After the two sets of intersecting rotating blades 6 come into contact with the material, they automatically disperse the material, pre-treating it and preventing large particles from affecting the mixing efficiency.

[0020] The driving mechanism includes a connecting rod 10, a cylinder 11, and a rotating arm 12. The connecting rod 10 is fixedly connected to one side of the sealing cover 4. The cylinder 11 is hinged to the bottom of the mixing box 1. The output end of the cylinder 11 is fixedly connected to the rotating arm 12. The interior of the rotating arm 12 is hinged to one end of the connecting rod 10. A sealing ring 13 is provided on the top of the sealing cover 4. The sealing cover 4 is fitted to the bottom end of the feeding pipe 2 through the sealing ring 13. The sealing ring 13 is an O-ring structure. The output end of the cylinder 11 is connected to the rotating arm 12. 2 is hinged to the connecting rod 10, and the connecting rod 10 is fixed to the sealing cover 4 as one piece. The output end of the cylinder 11 can drive the sealing cover 4 to rotate at the bottom end of the feeding pipe 2 through the connecting rod 10. The sealing cover 4 rotates upward and closes with the bottom end of the feeding pipe 2, sealing the bottom end of the feeding pipe 2 to prevent material from flowing out. The sealing ring 13 can fill the gap between the feeding pipe 2 and the sealing cover 4 to ensure sealing. When the sealing cover 4 rotates downward, it separates from the bottom end of the feeding pipe 2, and the material can flow out from the bottom of the batching box 1.

[0021] The automatic weighing device 3 includes a high-precision sensor that monitors the weight of the material in real time and automatically corrects the drop error through the control instrument. When the material approaches the set value, the system issues a stop signal in advance. After receiving the signal, the microcontroller on the cylinder 11 moves the controller to avoid over-dispensing and improve the measurement accuracy.

[0022] A dust collection hopper 14 is fixedly connected to one side of the mixing box 1, and a dust collection box 15 is provided on one side of the bottom of the mixing box 1. A dust collection mechanism is provided between the dust collection box 15 and the dust collection hopper 14, and a box cover is provided on the top of the dust collection box 15.

[0023] The dust collection mechanism includes a conveying pipe 16, a filter 17, and a fan 18. The dust collection hopper 14 is connected to one side of the dust collection box 15 via the conveying pipe 16. The filter 17 is connected to the other side of the dust collection box 15. A fan 18 is located on one side of the bottom of the mixing box 1. The input end of the fan 18 is connected to one end of the filter 17. The fan 18 draws air from inside the dust collection box 15, creating a negative pressure inside the dust collection box 15. The suction force is generated inside the dust collection box 15 by the pressure difference. The dust collection box 15 is then conveyed through the conveying pipe 16... Connected to the dust collection hopper 14, the dust floating on the top of the mixing box 1 flows to the dust collection hopper 14. The dust collection hopper 14 conveys the dust into the interior of the dust collection box 15 through the conveying pipe 16. The filter 17 can separate the dust from the air and trap the dust inside the dust collection box 15. After the interior of the dust collection box 15 is full of dust, the box cover is opened to collect and remove the dust for use. The filter element stuck inside the filter 17 is removed and cleaned. Then the filter element is installed back into the filter 17, and the box cover is put back on the top of the dust collection box 15.

[0024] In this concrete batching machine, the output end of the rotary motor 7 can drive one of the rotating shafts 5 to rotate, and then drive the other rotating shaft 5 to rotate synchronously through the pulley 8 and belt 9. The two rotating shafts 5 drive multiple rotating blades 6 on their outer sides to rotate together. After the two sets of intersecting rotating blades 6 come into contact with the material, they automatically disperse the material and pre-treat the material to avoid large particles affecting the mixing efficiency. The output end of the cylinder 11 is hinged to the connecting rod 10 through the rotating arm 12, and the connecting rod 10 is fixed to the sealing cover 4 as a whole. The output end of the cylinder 11 can drive the sealing cover 4 to rotate at the bottom end of the feed pipe 2 through the connecting rod 10. The sealing cover 4 rotates upward and closes with the bottom end of the feed pipe 2, sealing the bottom end of the feed pipe 2 to prevent the material from flowing out. The sealing ring 13 can fill the gap between the feed pipe 2 and the sealing cover 4 to ensure the sealing performance. When the sealing cover 4 rotates downward, it separates from the bottom end of the feed pipe 2, and the material can flow out from the bottom of the batching box 1.
