Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a method for shearing and crushing large pieces of garbage discharged from households, etc., into a size suitable for separation and incineration. It is related to the device.

[Conventional technology]

Bulky waste discharged from households, etc. needs to be finely crushed into pieces of 150 m or less for the purpose of metal recovery, etc. For this purpose, a crusher with a rotary hammer has traditionally been used, but sometimes gas cylinders are included in this bulky waste. The collision between the hammer and the iron generates sparks, which often causes large explosions and even buildings are destroyed, so rotary hammer set crushers are gradually being avoided. be. Instead, the fourth. A shearing machine as shown in FIG. Recently, a device using a shearing machine as shown in FIG. 7 has come into use.

That is, 4th. The one in Figure 5 has a horizontal blade 2 that has a blade shape 1 at its tip and moves vertically by the reciprocating motion of the piston.
cooperates with a fixed blade 4 installed on the upper edge of the bed 3 to longitudinally shear the compressed coarse material via a pusher and a stamper (not shown), and directly below the fixed blade 4. A plurality of vertical blades 5 provided vertically on the bed 3 work together with the horizontal blades 2 to shear the coarse material in the horizontal direction.Following the vertical shearing of the coarse material by the coarse fixed blade 4, the fixed blade 6 and the pushing cutting blade 7 are joined by a hinge 8, and the pushing cutting blade 7 is pushed from state A to state B by a piston reciprocating in a cylinder 9, so that coarse objects are pushed and crushed into smaller pieces. I have to.

[Problem that the invention seeks to solve]

However, such conventional 4. In the shearing machine shown in FIG. 5, as mentioned above, by lowering the horizontal blade 2, the fixed blade 4 works to shear the coarse material in the vertical direction, and at the same time, the vertical blade 5 works to shear the coarse material in the horizontal direction. Therefore, there is a problem in that a very large horsepower is required to lower the horizontal blade 2.

Also, 6th. A shearing machine like the one shown in FIG. 7 requires an extra cylinder and piston to drive the pushing cutting blade 7 for the second stage of shearing following the first stage of shearing, which reduces the cost. Furthermore, since the shearing work is performed using separate power sources, it takes a long time for shearing, and the efficiency is also low.

[Means for solving problems]

The present invention includes a first stage shearing section using a vertically moving horizontal blade and a fixed blade that cooperates with the horizontal blade, and a second stage shearing section that includes a vertical blade attached to the horizontal blade and an inclined fixed blade that cooperates with the vertical blade. The above-mentioned problem is solved by configuring this section.

Next, the present invention will be explained using the attached FIG. 1.

FIG. 1 shows a coarse object shearing and crushing device equipped with a butcher 12, a stamper 14, and a shearing machine, and the shearing machine includes a first stage shearing section consisting of a horizontal blade 16 and a fixed blade 18;
An inclined blade shape 21 attached to the front surface of the horizontal blade 16
A plurality of vertical blades 20 are formed, and a blade shape 25 is located below the fixed blade 18 and has an angle different from the inclination angle of the vertical blades 20.
It consists of a plurality of (2nd stage shearing parts by the ψ oblique fixed blade 22) formed thereon.

[Effect]

The coarse material that has been compressed to such an extent via the pusher 12 and the stamper 14 is moved to the fixed blade 18 by the lowering of the horizontal blade 16.
Sheared longitudinally by cooperation with (first stage shearing)
, the sheared object falls and rests on the inclined fixed blade 22. The subsequent lowering of the horizontal blade 16 causes the vertical blade 20 and the inclined fixed blade 2 to
2, the sheared object on the inclined fixed blade 22 is further sheared in a large number in the lateral direction (second stage shearing), becomes fine objects, and falls downward. Next, horizontal blade 1
6 will be raised and the shearing operation will be repeated.

〔Example〕

Embodiments of the present invention shown in FIGS. 1 to 3 will be described below.

In the figure, 11 is a garbage pit, 12 is a pusher driven by a hydraulic cylinder 13, 14 is a stamper that moves up and down by a hydraulic cylinder 15, and 1
4' shows the raised state; 616 is a horizontal blade which is moved up and down by the hydraulic cylinder 17; Reference numeral 18 denotes a fixed blade installed on the upper edge of the bed 19, which cooperates with the horizontal blade 16 to form a first stage shearing section. Reference numeral 20 denotes a plurality of vertical blades each having an inclined blade shape 21 attached to the front surface of the horizontal blade 16, and 22 denotes a plurality of vertical blades each having an inclined blade shape 21 attached to the front side of the vertical blade 20.
These are a plurality of inclined fixed blades in which blade shapes 25 are formed at angles different from the horizontal and oblique angles, and cooperate with the vertical blades 20 to form a second stage shearing section.

The coarse materials thrown into the waste bit 11 are sequentially sent by the busher 12 which is intermittently advanced by the hydraulic cylinder 13, and while the stamper 14 is raised to the position 14' by the hydraulic cylinder 15, the stamper is removed. The coarse material is then fed in a fixed amount into the lower part of the stamper, and as the stamper descends, it is compressed and crushed to the extent that it is pressed down. At this time, the hydraulic cylinder 17
As a result, the horizontal blade 16 located above is lowered and the third a
(Fig.), the coarse object located in front of the stamper 14 is sheared in the vertical direction by the cooperation of the horizontal blade 16 and the fixed blade 18 (first stage shearing). Then, the sheared object S falls onto the inclined fixed blade 22 installed below the fixed blade 18 (FIG. 3b). Furthermore, as the horizontal blade 16 descends, the plurality of vertical blades 20 attached to the front side of the horizontal blade push the sheared material S, and in cooperation with the inclined fixed blade 22, sequentially remove the acid S from above. Multiple shears are applied in the lateral direction (second stage shearing).

In this way, the coarse object is sheared and becomes many fine objects s', s', . . . (FIG. 3C), which fall downward.

After shearing the coarse material, the horizontal blade 16 is moved to the hydraulic cylinder 17.
This will cause the shearing process to be repeated.

〔Effect of the invention〕

As described above, the apparatus for shearing and crushing large objects according to the present invention can remove large objects in one stroke by simply installing a plurality of vertical blades in front of a horizontal blade and installing a plurality of inclined fixed blades below the fixed blade. The coarse material is sheared finely as desired, and since there is a step between the vertical and horizontal cuts of the coarse material, the force required for shearing is small. Since the fixed blades have different inclination angles, shearing at the core is performed sequentially as if using scissors, so the force required for shearing can be even smaller. Therefore, only a small horsepower is required to move the shearing blades.

Furthermore, since it is not necessary to use a separate drive device for the second stage shearing, the shearing time can be shortened, and efficiency can be increased accordingly, and the cost can be reduced.
