Description

Novel vertical silo cleaning mechanical device

Technical Field

The utility model relates to the technical field of silo cleaning, in particular to a novel vertical silo cleaning mechanical device.

Background

The flour bin is a basic device for storing, processing and transporting flour in a flour mill, and most of flour bins are cylindrical structures, and the number of flour bins is small. In the development progress of society, the demand of society for wheat flour is increasing, so that the flour bin is also increasing in importance, and the scale and the mechanization degree of the flour bin are also increasing. After flour in the flour storehouse stores for a period of time, because the influence of humidity and inside-outside difference in temperature of flour itself, there is some flour hardening unable to drop on the storehouse wall, this can very big influence to flour quality, on the other hand can influence the output of flour again, and the flour of hardening also can cause the influence damage to flour storehouse itself in addition to a certain extent. At present, the flour bin is mostly cleaned manually, the manual cleaning of the flour bin is extremely troublesome and dangerous, workers hang down through the bin opening at the upper part, the flour bin is cleaned by adhering to the bin wall, the action is inconvenient, and meanwhile, the dust concentration in the bin is too high to cause explosion, so that lives and properties of the workers are seriously threatened.

Therefore, there are some places to use robots for the management. But the cleaning robot that now used simple structure, the function is single, only comprises robot main part and arm, hangs the robot through wire rope and carries out the clearance, and this kind of mode makes the robot be difficult to fixed position in the powder storehouse, and equipment is huge, and the clearance is got up comparatively difficultly, and the robot still is difficult to keep balanced. And the cleaning is controlled by workers, so that the labor is wasted, and meanwhile, the bacterial pests after the cleaning cannot be cleaned. Some people also propose to use a wall climbing robot, but the inner wall of the powder bin is of an arc structure, flour powder blocks are arranged on the powder bin, and the robot is difficult to adsorb on the bin wall. Therefore, a more efficient, more stable and convenient powder bin cleaning robot is needed.

The Chinese patent of the invention with the publication number of CN113799154A discloses a cleaning robot, which relates to the technical field of cement silo cleaning equipment, and comprises a platform mounting frame, a lifting assembly, a telescopic assembly and an operating assembly; the upper end of the lifting component is rotatably arranged on the platform mounting frame.
