Technical Field

[0001] The utility model relates to the technical field of concrete production equipment, in particular to a raw material storage bin of a concrete mixing station. Background Art

[0002] A large amount of sand and gravel is used in concrete production. Therefore, concrete production companies will use special silos to store sand and gravel. Most of the existing silos are equipped with multiple partition rooms to achieve classified storage of sand and gravel raw materials of different specifications and types.

[0003] China's authorization announcement number CN210049660U discloses a concrete sand and gravel raw material storage silo, including a silo body, a silo opening is arranged on the silo body, and a plurality of partition rooms are arranged inside the silo body, which are formed by the inner wall of the silo and two adjacent isolation walls. The silo body includes a concrete structural wall arranged in a rectangular frame shape and open at the upper end, and a metal shed installed on the concrete structural wall and open at the lower end. The metal shed includes a metal frame fixed in the concrete structural wall and a metal shell covering the outer wall of the metal frame. The utility model has the advantage of reducing the construction cost of the sand and gravel storage silo.

[0004] However, the device has the following defects when in use: although the device has the advantage of reducing the construction cost of the sand and gravel storage silo, the device still needs to use a forklift or other equipment to transport sand and gravel into the silo for unloading when storing materials. Therefore, due to the limited height of the forklift during unloading, it is difficult to pile up the raw materials higher, affecting the actual utilization rate of the storage silo. In view of the above defects: To this end, we propose a raw material storage silo for a concrete mixing station. Utility Model Content

The classification structure includes a plurality of partition plates 10 fixedly installed on the inner wall of the bin body 1 at equal intervals. The interior of the bin body 1 is divided into a plurality of storage cavities 11 by the plurality of partition plates 10. Inner top walls of the plurality of storage cavities 11 are provided with feed ports 12. The plurality of storage cavities 11 can be used to store various types of concrete raw materials.

[0026] The upper surface of the storage bin body 1 is provided with a raw material conveying structure for conveying raw materials. The raw material conveying structure includes a support frame 2 fixedly installed on the upper surface of the storage bin body 1, and a feeding assembly and a pushing assembly respectively arranged on the upper surface of the support frame 2. The feeding assembly includes a conveyor belt 3 arranged on the inner wall of the support frame 2.

[0027] The pushing assembly includes two mounting frames 4 respectively fixedly mounted on the upper surface of the support frame 2, and a guide rail 5 is fixedly mounted on the back of the two mounting frames 4.

[0029] The driving motor 20 can drive the driving pulley 7 to rotate, so that the belt 9 can be used to pull the push plate 6 to move above the storage bin body 1, and the guide track 5 can guide the moving trajectory of the push plate 6. Therefore, according to the type of concrete raw materials, the driving component can be used to drive the push plate 6 to move above the designated storage cavity 11.
