Description

[Detailed description of the invention] (a) Industrial application field The present invention is used in the field of compressing garbage and forming it into a log shape.

(b) Prior Art As shown in FIG. 1, a conventional garbage compression processing apparatus is provided with a hopper 02 for charging garbage on the base side of a cylindrical casing 01, and a screw 04 having a spiral blade 03 in the casing 01. It has a structure with

However, in the above structure, the garbage located inside the hopper moves toward the front wall of the hopper along with the garbage that is transferred forward by the screw, but once it comes into contact with the front wall of the hopper, it cannot move forward any further. As a result, the dirt is deposited on the inner surface of the front wall of the hopper as shown by the solid line and the dashed-dotted line in Figure 1, and the opening area for supplying dirt into the screw gradually decreases from A to A, resulting in extremely poor processing efficiency. There were flaws.

(c) Problems to be solved by the invention The present invention attempts to solve the above-mentioned drawbacks by providing an auxiliary screw for transporting the garbage to the rear in parallel with the screw for compressing the garbage in the hopper. This is what I did.

(d) Means for solving the problem The present invention provides a hopper for throwing in garbage at the base of a cylindrical casing, a main screw is rotatably provided in the casing, and the garbage is collected by rotating the main screw. A garbage compression processing device that compresses and shapes into a log shape while transporting it forward, wherein the hopper is provided with an auxiliary screw in parallel with the main screw that can transport the trash in the hopper backwards. It is.

(e) Embodiment An embodiment will be described below with reference to the drawings. Reference numeral 1 denotes a cylindrical casing, and a hopper 2 into which garbage can be thrown is provided above the base side of the casing 1.

A main screw 5 consisting of a main shaft 3 that is somewhat shorter than the casing 1 and a main blade 4 spirally provided on the main shaft 3 is rotatably installed inside the casing 1. A second drive device 6 provided on the base side of the casing 1
It can be rotated in the direction of the arrow in the figure.

An auxiliary screw 7 is rotatably provided in the hopper 2 in parallel with the main screw 5, and the auxiliary screw 7 is forcibly rotated in the same direction as the main screw 5 via a transmission member 8 such as a belt. It is becoming more and more popular.

The auxiliary screw 7 has an auxiliary blade 1 on an auxiliary shaft 9.
0 in a spiral shape, and in particular, the auxiliary blades 10 are shaped so that when the auxiliary shaft 9 is rotated in the direction of the arrow in FIG. 2, the garbage in the hopper 2 is transferred to the rear. .

The present invention has the above-mentioned structure, and its operation will now be explained. First, the drive device 6 is operated to rotate the main screw 5 and the auxiliary screw 7 in the direction of the arrow as shown in FIG.

After that, when the garbage is put into the hopper 2, the garbage passes through the hopper 2 and enters the casing 1. The dust that has entered the casing 1 is compressed and transferred forward by the main blade 4 of the main screw 5, and as this action is carried out continuously, the dust is formed into a log shape from the front opening of the casing 1. It will be discharged.

By the way, the dust overflowing from inside casing 1,
In other words, the garbage located in the hopper 2 tries to move forward together with the garbage in the casing 1, but
Since the auxiliary screw 7 is rotating in the direction of the arrow in FIG. 2, it is prevented from moving forward and, on the contrary, is transported backward and supplied to the base side of the main screw 5.

This prevents the dust in the hopper 2 from adhering and accumulating on the inner surface of the front wall of the hopper 2.
There is no need to worry about the opening area for supplying dust to the side being narrowed.

In the embodiment, the main screw and the auxiliary screw are rotated in the same direction, but this structure is not necessarily limited. If so, they have similar effects.

(f) Effect of the invention As described above, the present invention has an auxiliary screw installed in the hopper in parallel with the main screw, and the rotation of the auxiliary screw allows the garbage inside the hopper to be transferred to the rear. The problem of dust adhering and accumulating on the front wall of the hopper and narrowing the opening area for supplying dust to the main screw side is completely eliminated, and processing efficiency can be significantly improved.

[Brief explanation of the drawing]
