[0002] Concrete mixing station, also known as concrete prefabrication plant, is a joint device used for centralized mixing of concrete. It consists of five major systems, including mixing host, material weighing system, material conveying system, material storage system, control system, and other ancillary facilities. Among them, the ground warehouse type batching machine is one of its main systems. Trucks transport raw materials and unload them into the aggregate silo. There is no detection feedback function in the existing equipment. The unloading speed of the truck is completely controlled by the driver. If the unloading is too fast, the raw materials are easily piled up and overflowed. The long-term overload of the grid plate will also affect its service life. Therefore, it is necessary to design a ground warehouse type batching machine for concrete mixing station. Summary of the invention

DETAILED DESCRIPTION
[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0017] like Figure 1-Figure 4As shown, the ground-bin batching machine of the concrete mixing station includes an electric control cabinet 2 and a grid plate 1 installed above the aggregate bin. In this embodiment, the raw materials loaded from the outside truck will be poured into the aggregate bin. When batching, the required raw materials are weighed and sent into the batching box through a conveyor belt. This adopts the existing technology; the grid plate 1 has left and right side plates 17 on both sides, and the grid plate 1 has a rear side plate 5 on the rear side. Specifically: the rear side plate 5 is an arc-shaped plate; a U-shaped beam 4 is installed on the rear side plate 5, and a track 13 is horizontally fixed on the U-shaped beam 4. A slide seat 12 is slidably connected to the track 13. The slide seat 12 is connected to the control table 11. The control table 11 is connected to a driving mechanism that can make it move back and forth. A connecting block 16 is rotatably connected to the control table 11, and the connecting block 16 is connected to a swing rod 15. One end of the swing rod 15 is connected to the detection bucket 3, and the other end of the swing rod 15 is connected to the touch column 9. A travel switch 19 matched with the touch column 9 is installed on the control console 11. There is also an inclined support spring 14 between the control console 11 and the swing arm 15. The travel switch 19 is electrically connected to the electric control cabinet 2 through a line. The electric control cabinet 2 is also connected to a two-color indicator light 8. With this structure, when the truck unloads raw materials, a part of the raw materials will enter the detection bucket 3, and then enter the aggregate bin after passing through the grid plate 1 from the detection bucket 3. When the unloading speed of the truck is too fast, materials will accumulate in the detection bucket 3, causing the detection bucket 3 to swing downward, and then the touch column 9 will contact the travel switch 19 and transmit the signal to the electric control cabinet 2. The electric control cabinet 2 causes the prompt light to give an alarm prompt, so that the truck driver reduces the unloading speed. After the accumulated materials are eliminated, the prompt light releases the alarm, thereby ensuring the unloading rate while ensuring that a large amount of raw materials will not accumulate on the grid plate 1 in an instant.
[0018] The driving mechanism includes a bracket 7 and a push rod motor 6. The bracket 7 is installed above the aggregate bin and is located behind the rear side plate 5. The push rod motor 6 is installed on the bracket 7, and the push rod of the push rod motor 6 is arranged horizontally. The push rod end of the push rod motor 6 is connected to the control table 11, and the push rod motor 6 is electrically connected to the electric control cabinet 2 through a line. With this structure, after the truck drives to the unloading position, the control table 11 is driven to move outward by the push rod motor 6, so that the control table 11 can be moved to the top of the grid plate 1; an auxiliary roller 10 is also installed on the bracket 7.
[0019] A vibration motor 18 is also installed on the detection bucket 3, and the vibration motor 18 is electrically connected to the electric control cabinet 2 through a line. With this structure, the detection bucket 3 can generate vibration to ensure that the raw materials pass through the detection bucket 3 smoothly. In this embodiment, the electric control cabinet 2 adopts an existing product, and it is connected to other components using existing technology, and its circuit does not need to be redesigned.
[0020] In the utility model, a detection bucket 3 that can swing up and down is provided. When the truck unloads raw materials into the aggregate bin, the detection bucket 3 can always detect the unloading amount of the truck, thereby ensuring the unloading rate while ensuring that a large amount of raw materials will not be accumulated on the grid plate 1 in an instant.
