DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus capable of efficiently crushing plastic molded articles such as plastic films and plastic caps mixed therein when treating garbage and other wastes. It is about.

[0002]

2. Description of the Related Art Heretofore, as a household or business garbage disposal apparatus, for example, those shown in a side sectional view of FIG. 4 and an exploded perspective view of FIG.
-4474). This apparatus has one end opened and covered with a perforated plate 2 and the other end 3 closed, an object to be treated, that is, a garbage input port 4 provided above, and a plurality of feed grooves 5 on the inner wall surface.
, And a screw 6 rotatably mounted in the casing 1 such that the tip thereof is rotatably opposed to the perforated plate 2 via a cutting member 7.
Center hole 9 of perforated plate 2 fixed from outside by lid 8
Is supported by On the other hand, the cutting member 7 has three blade supporting pieces 10,... Protruding radially, and provided on its rear surface with cutting blades 11,... Which are mounted so as to rotate coaxially with the screw 6. I have. And the garbage thrown in from the slot 4 is sent forward through the feed grooves 5,... While being pulverized by the screw 6,
While being dehydrated during this time, it is cut into small pieces by the cutting member 7 and discharged as dehydrated strips through the holes of the perforated plate 2.

However, garbage often contains polyvinyl chloride bags, plastic wraps, plastic caps and the like used for packaging, and these are supple and resilient. It can not be cut finely by the action of screws and cutting members, sent forward while twisting in the casing,
It gradually becomes string-like, is pushed between the cutting member and the screw and the perforated plate, and is entangled with the rotating shaft.

[0004]

DISCLOSURE OF THE INVENTION The present invention overcomes the drawbacks of the conventional garbage disposal apparatus and can easily crush plastic molded products even if they are mixed in the garbage. The purpose of the present invention is to provide an apparatus capable of processing garbage smoothly.

[0005]

Means for Solving the Problems The present inventor has conducted intensive studies to develop an apparatus for efficiently pulverizing garbage mixed with plastic molded articles. The tip of the screw is formed into a frustoconical shape, and the cutting member is completely inserted into the front face of the cutting member. It has been found that the purpose can be achieved by engraving grooves that can be accommodated, and the present invention has been accomplished based on this finding.

That is, according to the present invention, one end is opened, covered with the perforated plate 2, the other end 3 is closed, and
, A crushing device comprising a cylindrical casing 1 in which a plurality of feed grooves 5,... Are engraved on the inner wall surface, and a screw 6 rotatably mounted with the tip thereof in contact with the perforated plate 2 therein. In the above, the tip 6 ′ of the screw 6 is formed in a tapered frustoconical shape, and a groove 13 for fitting a cutting member 7 provided with a plurality of blade supporting pieces 10 in a radial pattern is formed on the front surface of the frustum. The depth of the groove 13 is made substantially equal to the thickness of the cutting member 7, and the front and rear surfaces of the blade supporting pieces 10,.
The present invention provides a garbage processing apparatus characterized in that the garbage processing apparatus is formed as follows.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side sectional view showing an example of the apparatus of the present invention, which is open at one end, covered with a perforated plate 2, closed at the other end 3, and is provided with a workpiece inlet 4 at the top. , A cylindrical casing 1 in which a plurality of feed grooves 5,... Are engraved on the inner wall surface, and a screw 6 rotatably provided therein.
There is no substantial difference from the prior art in having the structure with the. In addition, as shown in FIG.
And the pitch of the spiral is equal to the length of the inlet, and the lead angle of the first spiral mountain connected to the base end is smaller than the lead angle of the other spiral mountain, It is preferable to use one with improved speed and crushing efficiency.

The screw 6 in the apparatus of the present invention
As shown in the perspective view of FIG. 2, the tip 6 ′ is brought into direct contact with the perforated plate 2 to form a tapered truncated cone, and the blade supporting pieces 10, , And a plurality of grooves 13 extending radially outward from the central axis for fitting.... And the depth of the grooves 13,. It is necessary to make them substantially equal so that when the cutting member 7 is fitted, no gap is formed between the front surface of the cutting member 7 and the rear surface of the perforated plate 2. In addition, the cylindrical casing 1
The portion of the inner wall of the distal end where the cutting member 7 fits is formed in a cylindrical shape cut to the same depth as the depth of the groove 13.

The cutting member 7 is shown in FIG.
As shown in the perspective view of FIG. 2, a plurality (three in the figure) of blade support pieces 1 protruding outward from a cutting member 7 having a shaft hole 12.
And the blade carrying pieces 10,.
, It is necessary to provide cutting blades 11,..., 11 ′ (11 are not visible) on the front and rear surfaces. The blade supporting pieces 10,... Need to be formed to have a length so as to be in contact with the inner wall of the distal end portion of the cylindrical casing 1.

[0010]

In the apparatus of the present invention having such a structure, when garbage including a plastic molded article is introduced from the introduction port 4,
A relatively large portion of the garbage is pushed forward by the screw 6 and reaches the front end of the casing 1 through the feed grooves 5,. It is crushed by the partition mountain and the outer diameter spiral of the screw 6, and is finely divided. Next, the garbage that has reached the front end of the casing 1 is further cut by cutting blades 11,..., 11 ′ (11) provided on the front and rear surfaces of the cutting member 7.
Crushed finely and discharged through the perforated plate 2. During this time, plastic molded articles mixed in the garbage, for example, a polyvinyl chloride bag or a plastic wrap film, are wound around the screw 6 and twisted and gradually formed into a string. It is torn off by the spiral of the screw and the outer diameter of the partition and reaches the screw tip 6 ′ while being cut. This portion is the three blade-carrying pieces 10 of the cutting member 7.
Is divided into three separate spaces by
The movement of the string-shaped plastic molded product is restricted, stays in the same space, and is pushed out to the perforated plate 2 by the following garbage without being wound around the rotating shaft or the cutting blade. Moreover, the screw tip 6 ′ is formed in a tapered frusto-conical shape and has a slope toward the front, so that garbage can be efficiently pressed against the perforated plate 2 and provided on the front surface of the cutting member 7. Are further pulverized and discharged by the cutting blades 11 '. According to the apparatus of the present invention, not only plastic molded articles but also contaminants such as disposable chopsticks and paper can be simultaneously processed.

[0011]

According to the present invention, the contaminants such as plastic molded articles and wood chips, which were difficult to grind with the conventional garbage processing apparatus, can be directly processed without performing an operation of removing them in advance. , Plastic bags, plastic lunch containers, disposable chopsticks, air caps,
This is extremely advantageous when processing garbage mixed with a packing string or the like.
