Abstract

PURPOSE:To prevent crushed materials from flowing back and an impact plate from becoming worn out lopsidedly as well as enhancing crushing effects in a reversible rotatable impact-type crushing machine. CONSTITUTION:A crest-shaped chute member 4 which changes the flow of crushed materials charged from a charge hole 3 to the right/left, is arranged slightly below the charge hole 3 for crushed materials in a casing 1. In addition, charge chutes 5a, 5b are located at each area between the right/left inclined surfaces 5a, 5b of the chute member and the upper lateral surface of the easing 1. Further, closable dumpers 6a, 6b are provided at the top openings of both charge chutes 5a, 5b, and closable repulsive plates 9a, 9b are arranged at a bottom opening. The repulsive plates 9a, 9b constitute part of the chute to change the flow direction of crushed materials which drop through the charge chutes 5a, 5b when the plates 9a, 9b are open, toward a rotor 2 from above the lateral part of the rotor 2. The repulsive plate 12 is arranged with a required space left between the bottom of the chute member 4 and the rotor 2.

In this known impact type crusher, a rotor having striking plates mounted at circumferentially equidistant positions on the outer periphery is installed in a casing which also serves as a body frame so as to be rotatable in the forward and reverse directions. Repulsion plates are arranged on both sides, and the material to be crushed, which is charged from the charging port in the upper part of the casing, is crushed by the impact plate and the repulsion plate on the outer circumference of the rotor.

By the way, in the conventional impact type crusher, the method of introducing the material to be crushed is the type directly below the center. That is, FIG.
As schematically shown in Fig. 1, the material inlet (3 ') for the material to be crushed is provided above the axial center of the rotor (2') in the casing (1 '). The material to be crushed falls directly onto the upper center of the rotor (2 ').

Therefore, the material to be crushed introduced from the inlet (3 ') is hit by the rotation of the rotor (2') (2).
Due to the impacting action of 0 '), there is a possibility that the crushed material that has been blown off may flow back to the charging port (3'), which may cause harm to the operator outside the machine.

In order to prevent this, as schematically shown in FIG. 3, a baffle plate (13 ') is provided at a portion of the chute (12') following the inlet (3 ') to bend the chute (12'). It has been proposed to perform some kind of work such as forming into a shape (see Japanese Patent Publication No. 61-56025), but even then, the backflow of the crushed material was not completely prevented.

Further, in any case, the material to be crushed is of the type directly below the center, so that the material to be crushed is difficult to disperse even when it is charged in the axial width as shown in FIG. It is easy for the impacting plate (20 ') to be unevenly worn (C), and in order to prevent this, it is necessary to put it in a width close to the machine width (W). It was also necessary to equip a wide feeder and conveyor.

Further, as shown in FIG. 2, since the material to be crushed is supplied to the upper center portion of the rotor (2 '), it is arranged on the side portion of the rotor from this supply position (the position where the striking plate strikes). The distance between the repulsion plates (9a ') and (9b') becomes shorter, and the crushing space that contributes to the crushing action is smaller than that of the single-rotation impact crusher, resulting in poor crushing efficiency. It was

Moreover, since the material to be crushed is supplied from the rear side in the rotation direction in the upper part of the rotor as described above, the distance from this supply position to the repulsion plate provided at the lower end opening of the other charging chute becomes long. As a result, the crushing space contributing to the crushing action in the upper part of the rotor becomes wider, and the crushing efficiency can be improved.

When the rotor (2) is reversely rotated in the counterclockwise direction in the drawing, contrary to the above, the upper and lower dampers (6a) and the repulsion plate (9a) of the charging chute (5a) are respectively drawn. In addition to the closed state as shown by the chain line, the dampers (6b) above and below the charging chute (5b) and the repulsion plate (9b) are respectively rotated as shown by the chain line in the drawing to be in the open state.

As described above, according to the present invention, it is possible to prevent the reverse flow of the raw material to be crushed to be fed, to perform the work safely, and to appropriately disperse the non-crushable raw material to prevent uneven wear of the striking plate. It can be prevented, and a large crushing space that contributes to the crushing action on the upper part of the rotor can be secured, increasing the number of hits with the hitting plate,
Crushing efficiency is improved.
