Of these, the transverse frame 10 is a rectangular frame so that the outer tub portion is sunk therefrom, thereby stabilizing the outer tub for placement on the transverse frame 10.

Specifically, as shown in fig. 1, a circle of friction belts, namely a front friction belt 4 and a rear friction belt 6, arranged around the drum wall is respectively arranged at two ends of the inner drum, wherein as shown in fig. 2, the front friction belt 4 is arranged in a tangent manner with a pair of driving wheels 12, and a single driving wheel 12 is erected on the front bracket 11 through bearing seats 14 at two sides of the single driving wheel 12, each driving wheel 12 is connected with an output end of a driving motor 13, and then under the driving action of the driving motor 13, a friction force is generated between the driving wheel 12 and the front friction belt 4, so as to drive the inner drum to rotate; the friction belt 6 is tangent to a pair of driven wheels 8, and the pair of driven wheels 8 are erected on the rear bracket 9 and play a role in lifting when the inner cylinder rotates, so that the inner cylinder rotates stably and smoothly.

Further, as shown in fig. 2 and 4, the front end 3 of the inner cylinder is open, and the edge part of the inner cylinder extends inwards to form a barrier edge with a blocking function; and an inclined channel 2 formed by extending a discharge port at the lower part of the smashing device 1 is communicated from the open part at the front end of the inner cylinder to the inside, and the inclined channel 2 is not contacted with the front end 3 of the inner cylinder, and only the inclined channel 2 partially extends into the inclined channel.

Further, as shown in fig. 1 and 4, the rear end 7 of the inner cylinder is open, and the edge of the inner cylinder is expanded outwards to form a trumpet-shaped opening, so that the screened waste sand materials can be conveniently cleaned out of the inner cylinder.

Further, as shown in fig. 4, the inner cylinder wall 15 in the middle of the inner cylinder is of a screen structure for screening the waste sand material which is not broken into pieces, and a plurality of brushes 16 which are arranged in a straight line are further arranged outwards from the inner cylinder wall 15, preferably, as shown in fig. 5, the brushes 16 are 4 and are distributed at the position of the quartering point of the circumference of the inner cylinder.

Specifically, as shown in fig. 2, both ends of the outer cylinder have the same inward-disposed containment edges, and the diameter of the opening is set larger than the outer diameter of the inner cylinder, so that the inner cylinder can be disposed through the openings at both ends.
