Further, the connection part between the dust suction pipe 7 and the fixed cylinder 8 is obliquely arranged, a filter screen 701 is arranged inside the dust suction pipe 7, the filter screen 701 is also obliquely arranged, and the lower edge of the filter screen 701 is close to the inner wall of the fixed cylinder 8.

The inclined dust suction pipe 7 and the filter screen 701 are arranged to block and filter off a small amount of adsorbed sand particles while removing dust, so that the small amount of sand particles can slowly fall along the inner wall into the accommodating space 21 below.

Further, a plurality of pulleys 6 are arranged at the top of the fixed cylinder 8, a plurality of pulleys 6 are also arranged on the side wall of the fixed cylinder 8, and the lifting rope 5 is connected with the winch 4 through the pulleys 6.

The pulleys 6 are arranged according to the height and the angle, the lifting rope 5 is wound along the pulleys 6, guiding and stress are facilitated, and the lifting of the lifting rope 5 can be controlled through the winch 4, so that the lower discharge end 904 and the telescopic cylinder 901 below are driven to lift.

Example two:

this embodiment provides another configuration of the mainframe.

As shown in fig. 7, a plurality of support columns 2 are arranged below the main frame, support legs 26 are connected below the support columns 2, and moving wheels 27 are arranged below the support legs 26.

The supporting column 2, the supporting legs 26 and the moving wheels 27 are matched, so that the main frame can be stably supported and can be moved as required, and the main frame can be flexibly moved on an operation site.

Example three:

the difference between the embodiment and the first embodiment is that a bucket-shaped material guide cylinder with another structure is provided.

As shown in fig. 8, an air flow channel 28 is provided inside the bucket-shaped material guiding cylinder 12, and a plurality of nozzles 29 communicated with the inside of the bucket-shaped material guiding cylinder 12 are provided on the air flow channel 28; the air flow passages 28 are connected to an external air source along the radial spokes 14 and the interior of the housing.

The air flow channel 28 is arranged in the bucket-shaped material guide cylinder 12, so that the air flow can be blown to the falling sand amount, and the mixed dust can be blown away by controlling the wind power, thereby being beneficial to the dust entering the dust suction channel.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
