[0005]

In this case, there is no problem as long as the object to be treated is a solid material which is easily broken. However, kitchen waste contains residual rice and the like. In the slit cutter portion, the cut pieces adhere to the slit cutter portion, and the cut pieces adhere to each other, form a rice cake, and are discharged in a state in which fine solids such as root vegetables are mixed. Therefore, it is not discharged downward, but adheres to the crushing blade and rises.
There is a problem that it adheres and accumulates on the surface.

For this reason, a method using a scraping member 70 shown in FIG. 6 instead of the shielding plates 60 and 61 has been attempted. This is to scrape off the crushed material adhering to each crushing blade. The scraping member 70 has a block shape having an angle α with the upper surface and the lower surface being inclined surfaces.
A groove is cut out so as to allow the passage of a comb, and the lower surface is obliquely downward, for example, the angle β is set to 45 degrees, and the crushed material attached to the crushing blade is attached to the crushing blade and raised by the lower inclined surface before rising. It is made to scrape. However, even in this state, sometimes the crushed material scraped by the scraping member 70 accumulates on the scraping surface, and it is difficult to remove the crushed material. This is because even if the crushed material attached to the scraping member tries to fall, the next crushed material pushes up from below, and therefore accumulates and falls after growing considerably, and this accumulation causes a failure. There are problems such as. In view of the above, an object of the present invention is to surely separate a crushed material from a crushing blade.

[0007]

According to a first aspect of the present invention, there is provided a pair of crushing rollers, each crushing roller having a plurality of disk-shaped crushing blades mounted thereon, the crushing blades being opposed to each other. In the waste crushing device for lapping the front end portion and shearing and crushing the supplied material, a scraping plate for scraping crushed material attached to each crushing blade is attached substantially vertically below the crushing roller. It is characterized by the following.

In the waste crushing apparatus of the present invention having the above-mentioned structure, the scraping plate for scraping the crushed material adhering to each crushing blade is mounted substantially vertically, so that the scraping plate is scraped by the scraping plate. The crushed material moves downward along the scraping plate, and the next scraped crushed material does not accumulate on the scraping plate by pushing it down.

According to a second aspect of the present invention, in the above structure, a notch portion is formed on the outer periphery of each crushing blade of the crushing roller, and an elastic scraping plate is provided behind the scraping plate so as to face each crushing blade. And the tip of the scraping plate rises following the rotation of the crushing blade, and returns at the notch to abut the next notch to remove crushed material remaining in the notch. It is characterized by doing.

According to the present invention having the above-described structure, it is possible to remove the adhering matter remaining in the notch portion of the crushing blade when the adhering matter is removed by the scraping plate.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the drawings. 1 and 2, a waste crushing device 1 has a pair of crushing rollers 3 and 4 arranged in parallel in a housing 2 similarly to the known structure, and each of the crushing rollers has a large number of disk-shaped members. The crushing blades 5 and 6 are attached, and the crushing rollers 3 and 4 are arranged close to each other so as to form a slit cutter portion by wrapping the opposing tip portions of the respective crushing blades. The crushing roller 3 is driven by a drive motor M via a transmission belt B, and is driven by a crushing roller 3 and a driven roller 4.
And the crushing roller 4 is rotated in the reverse direction. Numerals 8 and 9 denote cutout notches formed on the outer periphery of the crushing blades 5 and 6, respectively. The crushing roller may be driven by a hydraulic motor or an electric motor, and each shaft may be directly driven by a motor without using a transmission belt.

Reference numerals 10a and 10b (hereinafter, simply referred to as 10) indicate scraping plates disposed below the crushing rollers 3 and 4, respectively. The scraping plate 10 is cut into a comb blade shape so as to allow the crushing blades 5 and 6 to pass therethrough, and the tip is brought as close as possible to the body of the crushing roller.
It is installed almost vertically.

Reference numerals 11a and 11b (hereinafter, simply referred to as 11) denote scraping plates for removing extraneous matter remaining in the notches 8, 9 formed on the outer periphery of the crushing blades 5, 6. . The scraping plate 11 is formed of an elastic material, and has a length covering the cutout portions of the crushing blades 5 and 6,
In addition, a cut is made between each crushing blade so that each crushing blade can vibrate up and down. The illustrated example shows an example in which the scraping plate 11 is mounted on a horizontal plane passing through the axis of the crushing rollers 5 and 6.

In the above construction, the object to be processed introduced from above is crushed by the crushing blades 5 and 6 of the crushing rollers 3 and 4 and is transferred downward with the rotation of the crushing blade and discharged from the lower part. At this time, if the object to be treated is kitchen waste, it has adhesiveness and does not fall down.
Is scraped off. The scraped crushed material is still attached to the scraping plate, but the crushed material is sequentially sent out, whereby the crushed material attached to the scraping plate is sequentially pushed downward by gravity and accumulated. Nothing.

The crushed material remaining in the notches 8 and 9 of the crushing blade that has passed through the scraping plate 10 is discharged by the scraping plate 11. In other words, the scraping plate 11 is curved and its tip is lifted with the rotation of the crushing blade, and returns at the notch to apply an impact to the notch. As a result, the adhered crushed material is discharged to the left and right. In addition, this scraping plate is provided as necessary, and even if crushed material remains in the notch portion, it is usually discharged at the next cutting, but when the crushed material has a particularly viscous Is preferably removed by the scraping plate.

FIG. 3 shows another example of the scraping plate 11. The scraping plate 12 is curved from obliquely below and comes into contact with the crushing blade. After being lifted up by the rotation of the crushing blade, when returning by the notch portion, first, its tip is located in the back of the notch portion. In this case, the attachment is scraped off, and in this case, a cut is formed between the crushing blades so that each crushing blade can move up and down. Other configurations are the same as those of the previous example, and the same components are denoted by the same reference numerals and description thereof will be omitted.

In this case, when the scraping plate is returned, the tip first comes into contact with the inside of the notch, so that the scraping can be reliably performed from the inside of the notch.

[0018]

As described above, according to the present invention, since the scraping plate for scraping the crushed material adhering to the crushing blade is mounted substantially vertically below the crushing roller, the crushing The object is peeled off by the scraping plate. The stripped crushed material falls downward due to its own weight and is pushed downward by the next crushed material. That is, since the crushed material is sequentially extruded downward, the crushed material does not polymerize on the scraping plate, and can be reliably separated. Therefore, the crushed material is very effective as a device for crushing waste from a kitchen containing a viscous substance, for example, leftovers. Also, at this time, when the scraping plate is attached to the rear of the crushing blade facing the crushing blade together with the scraping plate, the crushed material remaining in the notch portion of the crushing blade that is difficult to remove by the scraping plate is removed. Can also be removed.
