Description

[Detailed Description of the Invention] The present invention relates to a crusher for crushing solid waste of various materials and shapes.

In recent years, with the rapid economic growth and rapid development of industry, large amounts of various solid industrial wastes have been generated. Conventionally, these industrial wastes were disposed of by incineration or burial. I came.

However, such waste disposal methods lead to industrial pollution, which has become a major social problem.

For this reason, such solid industrial waste is crushed, then incinerated after separating noncombustible materials, and other waste is collected, recycled, and treated for reuse from the perspective of resource reuse. Measures to do this have now been adopted.

Various types of crushers are used to crush such solid industrial waste, but as demand increases, crushers with higher crushing efficiency, longer crushing width, and less noise are being used. has come to be desired.

Furthermore, the above-mentioned crushers usually combine a fixed blade and a rotary blade to form an interlocking mechanism, but when each blade part wears out, the gap between each blade increases, and in particular, the shape of the blade increases. In the case of square teeth, even if you try to adjust the blade spacing by moving the square teeth forward relative to each other, it will only adjust the spacing with the opposing tooth, and this will be adjusted to prevent side wear of the square teeth. This has the disadvantage that it is not possible to do so, and this becomes a problem with the conventional apparatus along with the increase in the crushing width.

Therefore, in view of the above circumstances, the present invention eliminates the above-mentioned drawbacks of the conventional technology by adopting a crushing blade with a special tooth shape, and not only has high crushing efficiency and a long crushing width, but also prevents each blade from being worn out. The purpose of the present invention is to provide a crusher that allows for easy adjustment of the blade spacing during crushing, and that has improved ease of operation and safety.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of a crusher according to the present invention will be described below based on an embodiment shown in the drawings.

That is, the drive motor 4 and the reducer 5 are connected by a belt, and a chain 9 is wound between the reducer 5 and the sprocket 7.8.

One of the sprockets 7 is further configured to rotate a toothed upper roller 11 via a chain 10.

The other sprocket 8 is connected to rotate a sprocket 14 via a chain 8a, and to rotate a rotary tool rest 15 by a chain 14a wound around the sprocket 14.

An inclined bracket 16 fixed to the main body base 1 side is provided below the upper roller 11, and a hopper 17 is installed above the lower bracket 16.

A lower roller 18 facing the lower part of the hopper 17 and a lower roller 19 located slightly on the delivery side from the discharge port 17a of the hopper 17 are pivotally supported on the bracket 16.

The lower rollers 1B and 19 are rotated by the rotary arm or the drive motor 4 in response to the waste material placed in the hopper 17 falling on the bracket 16 under its own weight.

On the other hand, the main body base 1 is provided with a pair of left and right fixed blade mounting seats 20.21 facing the rotary tool rest 15, and a fixed blade 22 is attached to each of the fixed blade mounting seats 20.21 so that the blade can be freely extended. ing.

The rotary blade 3 is attached to the rotary tool rest 15 so as to correspond to the fixed blade 22 so as to be freely extended.

A hydraulic cylinder 12, one end of which is fixed to a bracket 1a protruding from the base body 1, is provided for opening and closing the lid of the entire apparatus.

Next, to explain the structure of the rotary blade 3, a large number of blades 23 shown in FIG. The blade 23 is attached to the rotary tool rest 15 in the form of a triangular wave shape in which a large number of said protrusions are laterally connected, as shown in FIG. It is set up so that

Adjustment of the blade protrusion of the rotary blade 3 is performed using a screw 24 that tightens the blade 23 to the rotary tool rest 15, as shown in FIG.
After slightly loosening screw 25, the set screw 29 is rotated left and right to adjust the blade spacing relative to the fixed blade 22.
, 25 are inserted into the holes 26 and 27 on the rotary blade seat side, which are formed in the shape of a long hole.

On the other hand, the fixed blade 22 uses blades having respective shapes as shown in FIGS. 5A, B, and C.

That is, the fixed blade 22a has a protrusion at the tip of the blade, the fixed blade 22b has a cutout on one side, and the fixed blade 22c has a cutout on the other side.

The fixed-blade blade 22a has a spatial shape created between the blades when a large number of these blades 22a are connected in a horizontal direction, which is similar to the tip 23 of the rotary-blade blade 23 shown in FIG.
The protrusion formed in a is designed to serve as a corresponding fitting part.

Similarly, the fixed blades 22b and 22c are also connected to each other so that the protrusion formed at the tip 23a of the blade 23 of the rotary blade serves as a corresponding fitting part.

Each fixed blade 22a, 22b, 22c has a long hole 30, 31.
It is fastened to the fixed blade mounting seat 20, 21 by inserting a screw into the blade, and by loosening the screw, the blade extension toward the rotary blade 3 side can be freely adjusted.

Either the fixed blade 22a is used in series, or the fixed blade 2
The selection of whether to use 2b and 22c in combination with each other is arbitrary and may be determined depending on the material and shape of the waste to be crushed.

Note that 32 shown in FIG. 1 is a mesh screen surrounding the lower part of the rotary blade 3.

When using the device of the present invention having the above configuration, first, when the drive motor 4 is driven to rotate, the sprocket 7.8 is rotated by the chain 9 that is wound around the reducer 5.
Sprocket 14 connected to sprocket 8 by chain 8a, and sprocket 14 and chain 14
The rotary tool rest 15 connected by a starts rotating.

At the same time, the upper roller 11 connected to the sprocket 7 by the chain 10 also starts rotating.

The upper roller 11 is supported only by its own weight on the lower roller 19, and the gap between both rollers is naturally adjusted according to the size of the waste thrown into the hopper 17, and the waste is transferred to the rotary tool rest 15. It works like sending it to the side.

The waste is guided by the lower rollers 18, 19 and the upper roller 11 and sent to the upper part of the rotary blade 3, and the blade 23 of the rotating rotary blade 3 and the fixed blades 22at 22b, 22c.
Sheared by the interlocking fitting part related to the combination.

When the crushed pieces are sheared into smaller pieces than the mesh screen 32, they fall downward from the mesh screen 32 and are discharged.

Therefore, by changing the mesh size of the mesh screen 32, the size of the waste that is sheared and falls can be freely adjusted.

When the fixed blade 22 or the rotary blade 3 is worn out and the distance between the two blades becomes too far apart while operating the device according to the above operation,
The distance between the two blades can be easily changed by adjusting the length of either or both of the blades.

That is, the screws 24 and 25 that tighten the rotary blade 3 and the push screw 2
The spacing between the blades can be easily adjusted by moving each blade by adjusting the rotation of the fixed blade 22 or by adjusting the screw that tightens the fixed blade 22, and then fixing the blades in an optimally meshed state.

This is because the shape of the blades in the meshing portion is substantially triangular, unlike the conventional square teeth, so that the spacing between the blades on the entire surface can be adjusted with only one adjustment.

As described above, according to the crusher according to the present invention, the fixed blade and the rotary blade are combined with a large number of blades, each blade is connected and assembled, and the respective blade edges are engaged with each other so that they fit into each other. Since the actual length of the crushing width can be set as long as desired, the crushing efficiency can be extremely high.

Furthermore, when the double-edged parts wear out, the blade spacing can be easily adjusted by simply adjusting the screws on the fixed parts of each blade, making it suitable for ease of operation and safety. It is effective.

It goes without saying that the crusher according to the present invention can be used not only for crushing industrial waste, but also for crushing various raw materials.
