Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a crushing device, in particular, a crushing device that can easily crush objects of high hardness such as dismantled automobile engines, and that has a crushing blade. The present invention relates to a crushing device that is less likely to be damaged, generates less noise during crushing, and is inexpensive.

[Conventional technology]

Conventionally, for example, in order to reuse an engine installed in a disassembled car as a resource, the bolts that assemble the engine were manually pulled out and the engine was disassembled into various parts. The parts were separated into ferrous parts, various non-ferrous parts, and combustibles, and the metals were melted down and reused.

In this way, when an engine is disassembled into parts and reused as resources, it is desirable to crush the various disassembled parts into even smaller pieces in terms of transportation, melting, etc.

[Problem to be solved by the invention]

However, in the past, crushing the various parts of a disassembled engine relied heavily on manual labor, requiring a great deal of labor. In addition, since a crusher using mechanical force requires a large press or the like, such a crusher is extremely expensive.

Therefore, it is an object of the present invention to easily crush hard objects such as automobile engines, with a crushing blade that is less likely to be damaged, and with less noise generated during crushing. The purpose is to provide an inexpensive crushing device.

[Means to solve the problem]

This invention has an input port for the object to be destroyed in the upper part,
a casing having a debris outlet formed in its lower part; a rotating shaft vertically attached to the center of the casing; a drive means for rotationally driving the rotating shaft; A disc-shaped crushing blade is rotatably and horizontally attached via an arm in multiple vertical stages, and a disc-shaped crushing blade is installed in the casing between the tip of the crushing blade and the inner surface of the casing at intervals in the circumferential direction of the casing. It consists of a plurality of vertically fixed chains, and the base end of the arm is horizontally and rotatably attached to the rotation axis.

Next, one embodiment of the crushing device of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of the crushing device of the present invention, and FIG. 2 is a sectional view taken along the line A--A in FIG. 1.

In FIGS. 1 and 2, 1 is a steel casing having an input port 1A for destructible materials in the upper part and a discharge port 1B for destructible materials in the lower part, and 2 is a central part in the casing 1. A rotating shaft 3 mounted perpendicularly to the rotating shaft 3 is a driving means for rotationally driving the rotating shaft 2. The drive means 3 includes a pulley 4 fixed to the lower end of the rotating shaft 2 and a motor 6 that transmits rotational force to the pulley 4 via a belt 5.

7 is a large-diameter drum fixed concentrically to the rotating shaft 2; 8 is an arm radially attached to the side surface of the drum 7 in multiple stages above and below; It is rotatably attached to the drum 7 in the horizontal direction to provide relief. Reference numeral 9 denotes a disk-shaped crushing blade rotatably and horizontally attached to the tip of each arm 8. 10
is a disk-shaped protection plate horizontally fixed to the side surface of the drum 7 on the arm 8 to protect the arm 8 and the crushing blade 9.

Reference numeral 11 denotes a plurality of chains vertically fixed at intervals in the circumferential direction of the casing 1 within the casing 1 between the tip of the crushing blade 9 and the inner surface of the casing 1.

Reference numeral 12 denotes a plate for preventing crushed materials from flying out, which is vertically fixed inside the casing 1 on the opposite side to the input port 1A.

According to the crusher of the present invention configured as described above, objects to be crushed having high hardness such as automobile engines can be crushed in the following manner.

When the object to be crushed is introduced into the casing 1 through the input port 1A, the object is repeatedly struck by the crushing blade 9 which is rotated at high speed by the driving means 3, thereby being crushed. and is discharged to the outside from the discharge port 1B. The crushed material crushed by the crushing blade 9 collides with the chain 11 arranged on the inner surface of the casing 1 without directly colliding with the inner surface of the casing 1. The inner surface of 1 will not be damaged. Moreover, the crushing blade 9 that strikes the object to be crushed is
Since the crushing blade 9 is disc-shaped and rotatable,
It rotates at the same time as it hits the object to be crushed. Therefore,
Since the entire circumference of the crushing blade 9 becomes a crushing blade and no single part is damaged, the crushing blade 9 has a long service life.

〔Effect of the invention〕

As explained above, according to the present invention, by making the crushing blade into a rotatable disk shape and further arranging a chain inside the casing, a highly hard object to be crushed, such as a dismantled automobile engine, can be crushed. This provides useful effects such as being able to provide a crushing device at a low cost that can easily crush materials, have crushing blades that are less likely to be damaged, and generate less noise during crushing.
