Description

Technical Field

[0001] The utility model relates to a cleaning device, in particular to a novel warehouse inner wall cleaning and arch breaking mechanism. Background Art

[0002] The existing technology for cleaning grain hanging on the wall of silo generally adopts manual cleaning. First, the gate of the grain outlet is closed, and then the work is done in the silo. The staff uses a long pole or an aerial work vehicle to handle it. When the vertical silo hangs on the wall, the staff enters the silo through the silo top hanging basket and uses long poles and other measures to handle it. When the position of the wall of a shallow circular silo is low, a loader is used to handle it, and when it is high, it is handled by an aerial work vehicle. Manual cleaning is dangerous and some residues will be left, which cannot effectively solve the problem of sticking or arching on the inner wall of the silo. Utility Model Content

[0006] In the above scheme, the pulse solenoid valve is first energized to open the piston, and compressed air enters the inner cavity of the air cannon. The compressed air impacts the piston rod, and the compressed air enters the interior of the silo. The air diffuses to the surroundings to form an annular shock wave, which impacts the remaining materials adhering to the inner wall of the silo or breaks up the arch structure of the materials, thereby solving the problem of not being able to effectively solve the problem of sticking or arching of the inner wall of the silo.

[0007] The end of the shell is arranged with an external thread, and the connecting piece is arranged with an internal thread matched with the external thread. The internal thread is sleeved with the external thread, and a fixed connection is achieved by matching the threads with each other.

[0008] The above solution connects the connecting piece to the housing by matching the internal thread with the external thread.

[0009] The connecting piece comprises a collar and a fixing block, the collar is threadedly connected to the housing, the fixing block is fixedly connected to the collar by bolts, and the fixing block is adapted to the pulse solenoid valve.

[0010] In the above scheme, the pulse solenoid valve is conveniently connected to the air cannon by setting the fixing block.

[0012] In the above scheme, by setting the boss, when the pulse solenoid valve loses power, the compression spring rebounds to pull back the piston rod, and the boss of the piston rod is located at the mouth of the shell to isolate the material from the air.

[0013] A piston is arranged at the end of the air intake pipe, and the piston is located in the air intake pipe, and the piston abuts against the air intake pipe opening.

[0014] In the above scheme, the piston is arranged to abut against the air inlet pipe opening.

[0015] The top diameter of the silo is larger than the bottom diameter and shrinks inwardly to form a funnel shape.

[0016] In the above scheme, the silo is funnel-shaped, which is convenient for compressed air to impact the residual materials on the inner wall of the silo or to break up the arch structure of the materials.
