Description

[Detailed description of the invention] The present invention relates to a crusher.

Conventional crushers are of the types shown in Figures 1 and 2. The crusher in Figure 1 is equipped with an electric motor 01 and a rotating shaft 02 with a hammer attached, and the rotating shaft is driven by a belt, so it has a special design. Belt 03 and pulley 04
The cost was high.

Furthermore, since the electric motor 01 of the crusher shown in FIG. 2 protrudes above the crusher, the amplitude of vibration on the electric motor 01 side is large, and the electric motor 01 has a disadvantage in that the vibration is not good. The present invention solves the above-mentioned drawbacks by incorporating the conventional electric motor outside the casing into the casing to reduce cost and vibration of the motor.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows a cross section of a crusher of the present invention, and the casing 1 of this crusher has a cone portion 3 having an input port 2 at the top and a discharge port at the bottom. It is formed by connecting the cylindrical portion 5 with the cylindrical portion 4.

An electric motor is built into the casing 1, and the electric motor includes a cylindrical motor case 6, a motor shaft 7 that projects vertically from the motor case 6, a stator 8 fixed to the motor shaft 7, and a motor case. The motor shaft 7 of the electric motor 11 is fixed to the top and bottom of the casing 1, respectively.

The motor case 6 has mounting plates 12, 12...
are welded in multiple stages in the vertical direction, and the mounting plates 12, 1
2. A hammer 13 is attached to the free end of the hammer shaft 14, which is inserted into the hole between the mounting plate 12, 12 and the hammer 13, 13, so that it can be detached and pivoted. supported.

Note that 10 is a lead wire that passes through the motor shaft 7 from outside the casing 1 and is connected to the stator 8. The present invention has the above-mentioned structure, and its operation will now be described. When electricity is supplied from the lead wire 10, a rotating magnetic field is created in the stator 8, and the rotor 9 and the motor case 6 fixed to the rotor 9 rotate. The rotational force is transmitted to the hammers 13, 13 through the mounting plates 12, 12, . . . and the hammer shaft 14.

Therefore, when waste is inputted from the input port 1, the waste is hit by hammers 13, 13, and is crushed from coarse to finely crushed in the cone part 2, further finely crushed in the cylindrical part 4, and then the waste is crushed into casings. 1 is discharged from the discharge port 4 below.

As described above, according to the present invention, an electric motor consisting of at least a cylindrical motor case and a motor shaft protruding vertically from the motor case is built into the casing, thereby improving the conventional type shown in FIG. In comparison, there is no need for special belts or pulleys, resulting in lower costs, and better resistance to vibration than the conventional type shown in Figure 2.

Claims (1)

[Claims] 1 A casing having an input port at the top and a discharge port at the bottom is formed, and an electric motor consisting of at least a cylindrical motor case and a motor shaft protruding vertically from the motor case is installed inside the casing. The upper and lower parts of the motor shaft are fixed to the casing, and a plurality of hammers are pivotally supported on the motor case in a plurality of vertical stages.
