Description

Technical Field

[0001] The utility model relates to the technical field of aggregate cleaning devices, in particular to an aggregate cleaning device for concrete processing. Background Art

[0002] Recycled concrete refers to the new concrete made by crushing, cleaning and grading discarded concrete blocks, mixing them with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc. Recycled concrete has the advantages of environmental protection and resource conservation.

[0003] Therefore, in the prior art, in order to ensure the subsequent production quality, the old concrete blocks are often required to be cleaned after being crushed. There are many devices that can clean aggregates in the prior art, such as drum cleaning machines. When the drum cleaning machines in the prior art clean aggregates, aggregates of appropriate sizes may be stuck in the mesh holes of the drum cleaning machines. This can easily lead to serious blockage of the mesh holes of the drum cleaning machines over a long period of time, and the effect of discharging mud is reduced. Therefore, in order to address this problem, an aggregate cleaning device for concrete processing needs to be improved. Utility Model Content

[0021] The cleaning mechanism includes a top frame 7, an electric push rod 8, a connecting seat 9, a cleaning drum 10, and hard bristles 11. The top frame 7 is arranged at the upper end of the bottom frame 1, and electric push rods 8 are fixedly arranged on both sides of the lower end of the top frame 7. The movable end of the electric push rod 8 is fixedly arranged with a connecting seat 9, and a cleaning drum 10 is movably arranged between the connecting seats 9 through a rotating shaft. A plurality of hard bristles 11 are evenly fixedly arranged on the outer surface of the cleaning drum 10. The hard bristles 11 in the cleaning structure can be inserted from the outside of the cleaning drum 4 into the through hole 5, so that the aggregate stuck in the through hole 5 can be squeezed out, so as to play the role of cleaning the cleaning drum 4, so as to prevent the through hole 5 of the cleaning drum 4 from being seriously blocked and unable to discharge the cleaned mud in time;

[0022] The cleaning drum 10 has friction rollers 12 fixedly disposed on both sides of the surface thereof, and the friction rollers 12 are in contact with the annular groove 6, so that when the cleaning drum 4 rotates, the friction rollers 12 and the cleaning drum 10 can be driven to rotate together;

[0023] The bottom frame 1 is provided with universal wheels 13 at the four corners of the lower end surface, and the universal wheels 13 can facilitate the movement of the entire device;

[0024] A motor 14 is fixedly arranged on one side of the surface of the bottom frame 1 through a mounting seat, a reducer 15 is arranged between the motor 14 and the rotating shaft 2, a power output shaft end of the motor 14 is transmission-connected to a power input shaft end of the reducer 15, and a power output shaft end of the reducer 15 is transmission-connected to the rotating shaft 2, the motor 14 can drive the reducer 15 to rotate, and thus the reducer 15 can drive the rotating shaft 2 and the supporting roller 3 to rotate, so that the friction force can drive the cleaning drum 4 to rotate continuously;

[0025] A water pipe 16 is arranged at the upper end of the interior of the cleaning drum 4, and the water pipe 16 passes through the cleaning drum 4. A plurality of nozzles are evenly and fixedly arranged on the outer surface of the lower end of the water pipe 16.

The water pipe 16 only passes through the cleaning drum 4 and has no contact with the cleaning drum 4. The whole can be supported by external pipelines.

[0026] Working principle: When using this device, the aggregate to be cleaned is inside the cleaning drum 4, and slides from the high point of the inclined cleaning drum 4 to the bottom. At this time, the rotation of the cleaning drum 4 can improve the cleaning effect of the aggregate;

[0027] During cleaning, aggregates of suitable size may be stuck in the through holes 5 of the cleaning drum 4. Such blockage of a large number of through holes 5 may affect the mud discharge effect of the cleaning drum 4. At this time, the friction roller 12 can be pushed to fit on the surface of the annular groove 6 by extending the electric push rod 8, and the hard bristles 11 can be made to fit on the surface of the cleaning drum 4. In this way, when the cleaning drum 4 rotates, the friction roller 12, the cleaning drum 10, and the hard bristles 11 are driven to rotate together. At this time, the hard bristles 11 can be inserted into the through holes 5 from the outside of the cleaning drum 4, so that the aggregates stuck in the through holes 5 can be squeezed out, thereby playing the role of cleaning the cleaning drum 4, so as to prevent the through holes 5 of the cleaning drum 4 from being seriously blocked and unable to discharge the cleaned mud in time.

[0028] When the device is in use, the electric push rod 8 can be retracted to drive the cleaning roller 10 and the hard bristles 11 to move upward, so that the hard bristles 11 are separated from the cleaning. In this way, unnecessary friction loss can be avoided when cleaning is not needed, thereby increasing the service life of the device.
