[0002] As we all know, sand and gravel aggregate is a general term for materials such as sand, pebbles, crushed stones, blocks, and stones in construction projects. Sand and gravel are often used as high-quality building materials and concrete raw materials due to their good hardness and stable chemical properties. They are widely used in houses, roads, highways, railways and other fields. With the requirements of infrastructure construction technology, there are higher requirements for the quantity and quality of sand and gravel. The hopper is one of the important auxiliary equipment in the processing of sand and gravel aggregates and plays an important auxiliary role.
[0003] The existing technology has the following problems:

[0026] In the present embodiment: when in use, the sand and gravel aggregates flow into the processing equipment through the discharge pipe 9, and the sand and gravel aggregates flow in the first slow flow chamber 10. Due to the shape of the first slow flow chamber 10, the sand and gravel aggregates have a preliminary buffering effect on the flow. Then, the air duct 12 is used to connect the fan. Under the operation of the fan, the falling sand and gravel aggregates are blown from the wind head to perform secondary wind blowing flow control. Finally, the sand and gravel aggregates enter the second slow flow chamber 11. Under the action of the baffle plate 13, the sand and gravel aggregates are subjected to tertiary flow control buffering. The utility model has a simple structure and is easy to operate. Through multi-stage flow control buffering operations, the sand and gravel aggregates enter the processing device at a uniform speed, which greatly improves the practicability of the device.

[0028] In this embodiment: when loading, the vibration motor 6 is started, and the arch breaking plate 4 is driven by the arch breaking frame 2 to perform arch breaking operations on the sand and gravel aggregates. Under the action of the damping spring 5, the arch breaking plate 4 is driven to perform a secondary jump, which can further improve the arch breaking effect of the arch breaking plate 4 on the sand and gravel aggregates and achieve an anti-blocking effect.
[0029] Specifically, the arch breaking frame 2 is a cross-shaped structure, and the arch breaking frame 2 is made of spring steel.
[0030] In this embodiment: the relatively excellent elastic performance is conducive to the vibration of the arch-breaking plate 4 to perform arch-breaking operations on sand and gravel aggregates.
[0031] Specifically, the first slow flow chamber 10 has a serpentine structure.
[0032] In this implementation scheme: it has a certain buffering and deceleration effect on the flow of sand and gravel aggregates.

Therefore, the control method and circuit connection will not be described in detail.
[0039] Working principle: when in use, the sand and gravel aggregate flows into the processing equipment through the discharge pipe 9, and the sand and gravel aggregate flows in the first slow flow chamber 10. Due to the shape of the first slow flow chamber 10, the sand and gravel aggregate has a preliminary buffering effect on the flow, and then the air duct 12 is used to connect the fan.
