Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a crusher for crushing objects to be crushed, such as waste capacitors.

(b) Prior Art As shown in FIG. 2, a conventional crusher has a cylindrical casing 01 connected to the base of a chute 03 having an input port 02 at the tip, and a hinge 04 above the tip of the chute 03. The hinge 04 was provided with a charging lid 05 for opening and closing the charging port 02.

For this reason, when putting the material to be crushed into the crusher, first open the input lid 05 from the solid line position to the dashed-dotted line position with one hand, and then input the material to be crushed from the input port 02 with the other hand.

(c) Problems to be solved by the invention However, while the material to be crushed is being fed into the casing, the material to be crushed is thrown up by the hammer, and a part of it enters the chute. There was a problem that the particles would not only fly out from the input port and stain the area around the crusher, but also hit and injure workers.

(d) Means for Solving the Problems The present invention has been made to solve the above problems, and includes a crusher in which the base of a chute having an input port at the end is connected to a casing. A hinge is provided at the lower part, and this hinge is provided with an input box that rotates in and out of the chute, closes the input port when rotated into the chute, and stores the material to be crushed when rotated outside the chute. It is characterized by a composition.

(e) Action The input box is rotated from the inside of the chute to the outside of the chute, the materials to be crushed are thrown into this input box, and when it is full, it is rotated into the chute and the materials to be crushed are thrown into the chute, and at the same time the input port is opened. is closed by the input box. The material to be crushed entered into the chute enters the casing, is bounced up by the hammer, collides with the protrusion, bounces back, and is bounced up again by the hammer, and is then discharged from the discharge port.

Incidentally, some of the objects to be crushed thrown up by the hammer enter the chute, but since the input port is closed to the input box, the objects to be crushed do not fly out.

(f) Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. Reference numeral 1 denotes a cylindrical casing consisting of a drum 2 with a circular longitudinal section and a pair of side plates 3, 3. A main shaft 4 is installed horizontally between 3 and 3, and a plurality of hammers 5... are provided on this main shaft 4.

In front of the drum 2 of the casing 1, a rectangular chute 6 with an open base is provided obliquely upward, and the tip forms an inlet 7. A hinge 8 is provided below the tip of the chute 6, and a charging box 9 is provided on the hinge 8 so as to be rotatable in and out of the chute 6. The objects to be crushed are stored in the chute (rotated outward position), and when it is full, the objects to be crushed are thrown into the chute 6 by rotating around the hinge 8.

10 is a discharge port provided below the drum 2 of the casing 1, and 11... are protrusions provided at appropriate intervals on the inner wall of the drum 2 of the casing 1. The present invention has the above-mentioned structure, and its operation will be explained next. First, the input box 9 is rotated about the hinge 8 from the position shown by the solid line in FIG. 2 to the position shown by the dashed-dotted line.

Next, the material to be crushed is put into the input box 9, and when it is full, it is rotated around the hinge 8 to throw the material to be crushed into the chute 6 and the input port 7 is closed.

The material to be crushed placed into the chute 6 enters the casing 1.

The object to be crushed that has entered the casing 1 is passed through the hammer 5...
. . ., collides with the protruding pieces 11 .

By the way, some of the objects to be crushed thrown up by the hammers 5 enter the chute 1 and try to jump out from the input port 7, but since the input port 7 is closed by the input box 9, they do not flow out. It won't jump out.

(g) Effects of the Invention As described above, the present invention is provided with a charging box that rotates to the inside and outside of the chute at the charging port at the tip of the chute. Since the input box closes the input port at the same time as the input is placed into the input port, even if the material to be crushed thrown up by the hammer enters the chute, it will be bounced back by the input box and will not fly out of the input port.

[Brief explanation of the drawing]

FIG. 1 is a vertical cross-sectional view of a crusher according to the present invention, and FIG. 2 is a vertical cross-sectional view of a conventional crusher. 1 is the casing, 6 is the chute, 7 is the inlet,
8 is a hinge, and 9 is an input box.

Claims (1)

[Claims] 1. In a crusher in which the base of a chute having an input port at the tip is connected to a casing, a hinge is provided below the tip of the chute, and this hinge can be rotated in and out of the chute, and when rotated into the chute, the A crusher that closes the input port and is equipped with an input box that stores the materials to be crushed when the chute rotates out of the chute.
