The skilled person can refer to the technical manual or dictionary or the specific structure and working principle of the arc-shaped sieve plate 21 disclosed in the present invention.
The arc sieve plates 21 are provided with arc sieve surfaces; because the two trommel assemblies 2 are symmetrically positioned, the trommel surfaces on the two trommel screens 21 face each other (i.e., the trommel surface on the left trommel screen 21 faces to the right and the trommel surface on the right trommel screen 21 faces to the left).
A plurality of crushing arc knives 211 are uniformly distributed on the arc screen surface of each arc screen plate 21, each crushing arc knife 211 is provided with a sharp stabbing surface 2111, each sharp stabbing surface 2111 faces upwards, when the materials are screened, the materials freely fall on the arc screen plates 21 and have certain kinetic energy, the materials impact the sharp stabbing surfaces 2111 on the crushing arc knives 211, and the materials are crushed.
The crushed material arc knives 211 are distributed in the following manner:
crushed aggregates arc sword 211 upper and lower distributes on the sieve bend face, and crushed aggregates arc sword 211 is preceding, the back distributes on the sieve bend face, simultaneously, is the arc because of sieve bend 21 is the arc, with sieve bend face shape fit of sieve bend 21, crushed aggregates arc sword 211 is the arc and distributes on sieve bend face of sieve bend 21.
The longitudinal section of each crushed aggregates arc cutter 211 is triangular, and the transverse section of each crushed aggregates arc cutter 211 is arc-shaped; a sharp stabbing surface 2111 of crushed material arc knife 211 is positioned on the inner side surface of crushed material arc knife 211 (the inner side surface of crushed material arc knife 211 is upward and is bent downward);
the arc of each spit knife 211 is 15 degrees.
The arc-shaped screen plate 21 is fixed through the screen frame 22, and the specific structure of the screen frame 22 is as follows:
the screen frame 22 comprises a top plate end fixedly connected to the top of the arc-shaped screen plate 21 and arc-shaped ends respectively fixedly connected to the front side wall part and the rear side wall part of the arc-shaped screen plate 21 (namely, the two arc-shaped ends are distributed in the front and the rear directions); the top of each arc-shaped end is fixedly connected with the bottom of the top plate end.
The arc-shaped screen plates 21 are fastened through the screen frame 22, and the screen frame 22 is assembled on the top of the base 1 through the bracket assembly. The specific structure of bracket component is as follows:
the bracket component includes four pole settings 221 of four welding in roof end bottom, and four pole settings 221 are preceding, back equidistance and distribute, and the bottom of every pole setting 221 all welds the horizon bar (not marked in the figure) towards base 1 top center, lies in the horizon bar on the bracket component of left side promptly and faces the right side, and the horizon bar on the bracket component that lies in the right side faces the left side.
The bottom of the vertical rod 221 is welded vertically to the end of the horizontal rod. In order to increase the stability, the horizontal rod is vertically connected with four transverse rods 2211 (the four transverse rods 2211 are arranged at intervals left and right), the horizontal rod faces left and right, and the transverse rod 2211 faces front and back. The horizontal rods are vertically staggered with the cross rods 2211 to form a field shape with stable support.
According to the prior art, each horizontal rod and the cross rod 2211 are connected to the top of the base 1 through a plurality of bolts (not shown), that is, the horizontal rods and the cross rods 2211 are connected to the base 1 through the bolts, so that the stability is increased.
