Abstract

PURPOSE:To finely cut articles to be cut and continuously throw the wastes in order to improve the processing capability by setting a large number of rows of combinations of rotary blades with fixed blades between a hopper and a screen. CONSTITUTION:A hopper 1 is installed in the upper part of a crusher 7 and a cutter apparatus 8 composed of fixed blades 4 and rotary blades 3 is installed under the hopper 1. In the cutter apparatus 8, blade parts are formed by fixing foxed blades 4a, 4b in installation parts 9 of the crusher 7 and setting rotary blades 3a, 3b in the lower sides of the fixed blades in the way the rotary blades are combined with the fixed blades while being set with a prescribed angle difference from the view of a flat plane. The crusher 7 is fixed, so that the screen 5 slides together with the blade parts in the lower side of the rotary blade 3b. In this way, a plurality of rotary blades are set at a distance in up- and-down-directions and a plurality of fixed blades are joined among the rotary blades and wastes are cut continuously in falling direction.

2. Description of the Related Art The above-mentioned prior application device is a cutter type, such as a PET bottle, which is hard to be crushed (the material is viscous and steel and the neck is thick), is cut with a blade. It was made possible to process with a small device that can be used in shops and homes as well. This is because the plastic bottle loaded in the hopper 1, as shown in FIG.
It is cut by a rotary blade 3 that horizontally rotates by the electric motor 2 and upper and lower fixed blades 4, and when this is cut into pieces that pass through the screen 5, it is dropped and stored in a storage case 6 below.

However, in this conventional device, the PET bottle is repeatedly cut by the rotary blade 3 and the fixed blade 4 until it is shredded to a size capable of passing through the screen 5. Until that was done, there was a drawback that the next charge could not be made.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to measure the drawback of the device of the prior application, that is, the processing capacity.

[0005]

[Means for Solving the Problem] Specifically, the hopper 1
Multiple rows of rotary blades 3 and fixed blades 4 are provided between the screen 5 and the screen 5, and as a result, the object to be cut put in the hopper 1 passes through the screen 5 sufficiently while it drops to the screen 5. It was cut into pieces that could be made, and as a result, it was possible to continuously input waste.

[0006]

The volume-reducing device of the present invention uses the waste material in the hopper 1
Then, it is cut into fine pieces one after another by a cutter device composed of a multi-row combination structure of a fixed blade 4 and a rotary blade 3 of the next order.
Shred into a size that can pass through the storage case 6 below
It is dropped and stored.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments of the drawings.
The hopper 1 shown in FIGS. 2 and 3 is attached to the upper part of the machine frame 7. Reference numeral 8 denotes a cutter device, which is fixed blades 4a and 4b horizontally attached to the lower side of the hopper 1 at vertical intervals and fixed to the machine frame 7 with attachment portions 9 at both ends, and the fixed blades 4a and 4b.
rotary blades 3a, 3b that slide and rotate below b, a screen 5 that is attached to the machine frame 7 and that slides and rotates with the rotary blade 3b at the lowermost portion on the upper surface, and an electric motor 2 that synchronizes the rotary blades 3a, 3b. It consists of and.

As shown in FIGS. 8 and 9, the rotary blades 3a and 3b are displaced by a predetermined angle from the center when viewed from the plane 2
Fixed blade 4 consisting of a combination of sheets with the end face in the rotating direction
The blade portion 1 is provided on the edge portion that slides on the a, 4b or screen 5.
0 is formed. Furthermore, the mounting portions 11 at both ends
Are fixed to mounting rings 13a and 13b provided inside the machine frame 7 via bearing devices 12a and 12b so as to be horizontally rotatable.

The mounting rings 13a and 13b have a pulley 1 on the outer circumference.
4 is integrally formed, and on the other hand, it is synchronized with a pulley 15 and a belt 16 on the electric motor 2 side. Other than this, the pulleys 14 and 15 may be used as gears for synchronization by a chain or a timing belt. The screen 5 is fixed to the machine frame 7 so that the upper surface of the screen 5 slides on the lower blade portion 10 of the rotary blade 3b. As shown in FIG. 5, the screen 5 is attached to the machine frame 7 with a large number of through holes 17 having blade portions 16 formed at the upper edge of the holes. Rotary blade 3
As shown in FIG. 4, a is attached to the attachment ring 13a so that the mutual blade portions 10 and 10 are on the upper side and the lower side, respectively, and through the stop hole 18 of the attaching portion 11. It is fixed with a bolt 19. This also applies to the other rotary blades 3b.

As shown in FIGS. 6 and 7, the fixed blades 4a and 4b are provided with a blade portion 20 at the edge facing the blade portions of the rotary blades 3a and 3b, and the fixing portions 21 at both ends are fixed. The bolts 23 are fixed to the machine frame 7 through the holes 22.

The storage case 6 is slidably mounted on the bottom plate 24 of the machine frame 7 below the screen 5.
Reference numeral 25 denotes a caster attached to the lower surface of the machine frame 7.

With the above construction, when the waste is put into the hopper 1, the waste is shredded in order while dropping the fixed blade 4a, the rotary blade 3a, the fixed blade 4b, the rotary blade 3b and the screen 5. It becomes a size that can pass through the through hole 17 of the screen 5, and is dropped and stored in the storage case 6 below.

When the crushed waste becomes full, the storage case 6 is pulled out in the direction of the arrow and discharged.

10 and 11 show the rotary blade 3 and the fixed blade 4.
It shows an embodiment in which the blade portions 10 and 20 of FIG. In this case, since the uneven portions 26 of the blade portions 10 and 20 bite into waste such as PET bottles to capture and cut it, the shredding efficiency is improved.

[0015]

[Effects] Since the present invention has the above-described configuration and operation, in a cutter-type waste volume reducing device that is designed to be compact and cost-reduced, waste can be continuously thrown in and processed. The processing efficiency can be improved.
