In the related technology, a concrete mixing device comprises a sand silo, a conveying belt and a mixing barrel, wherein the sand silo is arranged on the ground in a hanging way through a mounting frame, sand materials are contained in the sand silo, a discharge hole is formed in the bottom of the sand silo, and a cover body is arranged on the sand silo and can be opened and closed at the discharge hole; the conveying belt is erected below the sand silo, one end of the conveying belt is over against the lower part of a discharge port of the sand silo, and the other end of the conveying belt faces the stirring barrel; the feed inlet has been seted up on the agitator, and the feed inlet is located the below that supplies the conveying other end, and the agitator is used for carrying out the mixing stirring of raw materials such as sand material, cement and water.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: because the sand material is easy to damp and harden, the hardened sand material blocks are usually adhered to the inner wall of the sand silo or blocked at the discharge port of the sand silo, so that the sand material is difficult to normally discharge from the sand silo.

SUMMERY OF THE UTILITY MODEL

In order to improve the problem that is difficult to follow normal unloading in the sand silo after the caking that wets of sand material, this application provides a high-efficient convenient sand silo unloader.

The application provides a pair of high-efficient convenient sand silo unloader adopts following technical scheme:

the utility model provides a high-efficient convenient sand silo unloader, is including setting up the knocking mechanism on the sand silo, knocking mechanism is including being used for carrying out the impact piece that strikes and being used for the drive to strike the drive assembly that the piece function to the sand silo lateral wall, the discharge port department of sand silo is provided with and is used for carrying out broken sand block broken assembly to the sand block.

By adopting the technical scheme, a worker adjusts the driving assembly and the sand block crushing assembly, and the driving assembly drives the impact piece to knock the side wall of the sand silo, so that the hardened sand blocks knock and crack from the side wall of the sand silo and fall off from the side wall of the sand silo; then the sand block that drops under the effect of gravity to the discharge port department of sand silo, the broken subassembly of sand block carries out the breakage to the sand block, and the sand block is difficult for putting at discharge port department because of the too big card of volume this moment to make bonding state's sand block rub into tiny sand material, thereby improved the problem that is difficult to follow normal unloading in the sand silo after the sand material wets the caking, realized the quick spread of sand material in the sand silo.

Optionally, the impact member is an air hammer, the air hammer is fixedly arranged on the sand silo, and an impact end of the air hammer faces the side wall of the sand silo.

Through adopting above-mentioned technical scheme, during the use, the staff orders about the air hammer function through drive assembly, and the lateral wall in sand silo is strikeed to the impact end of air hammer to realize breaking fast and droing of the sand block on the sand silo lateral wall under the impact shock of air hammer, make the sand material be difficult for piling up the adhesion on the sand silo inner wall.
