DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show a schematic structure of a refuse supply device having a refuse bag breaking function according to the present invention.

In the drawing, reference numeral 1 denotes a housing of a dust supply apparatus, in which an input port 11 is formed at an upper part of the housing 1, a dust supply port 12 is provided at one end of a bottom portion, and a foreign matter discharge port 13 is provided at the other end. Has been formed.

Screws 3 are arranged in parallel in the housing 1, and both ends of the screw 3 are rotatably supported by the side wall of the housing 1 via bearings 3a.

Further, a first partition plate 4 is disposed in the housing 1 in a direction substantially orthogonal to the disposing direction of the screw 3. The first partition plate 4 is arranged closer to the dust supply port 12 than the charging port 11 is, and the first partition plate 4 is
The interior of the housing 1 is divided into a receiving portion 15 for receiving dust thrown in through the throwing port 11 and a feeding portion 16 on the dust feed port 12 side.

A through hole 41 for penetrating the screw 3 is formed in the first partition plate 4, and the diameter of this through hole is slightly larger than the diameter of the screw blade 31 of the screw 3.

A second partition plate 2 for partitioning the left and right screws 3, 3 is arranged in the supply section 16.

The screw 3 is, as shown in FIG.
The screw blade 31 is formed in a spiral shape on the peripheral surface of the shaft portion 32. In the screw 3, the portion arranged in the receiving portion 15 is continuously and integrally formed, and the portion arranged in the supply portion 16 is intermittently formed by a plurality of blade bodies 31a.

Here, in the plurality of blades 31a, adjacent blades 31a overlap each other in the axial direction of the screw 3 as compared with the locus of the continuously formed screw blades (see the chain double-dashed line). In the illustrated example, the end A of the blade 31a and the start B of the adjacent blade 31a are arranged.
And are configured to substantially coincide with each other in the axial direction of the screw 3.

By thus forming the plurality of blade bodies 31a, a gap is formed between the adjacent blade bodies 31a and 31a, and the gap causes the dust bag to be destroyed when the screw is driven as described later. The function of bagging is obtained. In addition, the plurality of blades 31 a also has the original transporting ability of the screw 3.

A plurality of fixed blades 51, 52 are provided on the inner wall of the housing 1 forming the supply section 16.
The fixed blade 51 is fixedly arranged on the bottom of the housing 1 formed by the supply unit 16, and the fixed blade 52 is fixedly arranged on the side wall of the housing 1 formed by the supply unit 16 and the second partition plate 2. These fixed blades 51 and 52 are for breaking the garbage bag together with the plurality of blades 31a, and also serve to roughly crush large garbage.

The two screws 3 and 3 thus constructed are separately and independently driven by the drive motors 6 provided on the sides of the housing 1. Drive motor 6
Has its output shaft 61 connected to one end of the shaft of the screw 3, and by driving the drive motor 6, the screw 3 can be rotationally driven in the forward and reverse directions.

The drive motor 6 is driven by an overload current when the drive motor 6 is loaded with a load more than a predetermined amount, that is, when the screw 3 is driven with a load more than a predetermined amount. 3 is configured to rotate in the reverse direction. The drive motor 6 normally drives the screw 3 to rotate so as to convey the dust from the receiving portion 15 side to the supply portion 16 side.

Further, as shown in FIG. 3, the housing 1 is divided into an upper housing 1a and a lower housing 1b vertically from a portion located substantially in the center of the screw 3 to be arranged, and bolts and the like. It is configured to be separable by releasing the appropriate fastening means. By thus separating the housing vertically, maintenance and repair can be easily performed.

Next, the operation of the dust supply device having the dust bag breaking function of the present invention will be described.

First, the garbage is introduced from the inlet 11 into the housing 1.
It is put in the receiving part 15 of. At this time, the screw 3 is rotationally driven so as to convey the dust from the receiving unit 15 to the supplying unit 16, and the dust introduced into the receiving unit 15 is conveyed by the screw blade 31 by the rotational driving of the screw 3. It is conveyed to the supply unit 16.

In the supply unit 16, the plurality of blades 31a formed on the screw 3 conveys the dust bag containing the dust to the dust supply port 12 while breaking the bag, and discharges the dust from the dust supply port 12. Specifically, in the supply unit 16, the dust bag is conveyed by the rotation of the screw 3 while entering the gap formed between the plurality of blade bodies 31a, and thus is conveyed while being caught in the gap between the blade bodies 31a. Further, due to the action of the fixed blades 51 and 52, the bag is further broken and carried out from the dust supply port 12.

Then, the discharged dust is conveyed to an appropriate subsequent device such as a sorting device or a drying device.

Further, the fixed blades 51 and 52 can roughly crush large-sized dust with the screw 3 in addition to the above-described bag-breaking function of the dust bag.

Since the plurality of blades 31a are arranged such that the adjacent blades 31a are overlapped with each other in the axial direction of the screw as compared with the loci of the continuously formed screw blades, the conveying ability is improved. Can be prevented from being significantly reduced, and the dust can be smoothly transported.

The dust thrown into the receiving portion 15 as described above is conveyed from the receiving portion 15 to the supplying portion 16 by the screw 3, and the through hole 41 is provided from the receiving portion 15 to the supplying portion 16. It is being inserted and transported. At this time, a large dust that does not pass through the through hole 41 and the screw 3 is clogged in the through hole 41, which impedes the rotational driving of the screw 3. In such a case, in the drive motor 6, since an overload current is generated, the screw 3 is rotated in the opposite direction by this overload current, and the dust clogged in the through hole 41 is regarded as a foreign substance and the foreign substance discharge port 13
Discharge from.

Specifically, for example, when dust is clogged in the through hole 41 and an overload current is generated, the screw 3 is slightly reversely rotated and then rotated normally again about three times. When the clogging of the dust cannot be cleared at 41, the screw 3 is reversely rotated for a time sufficient to be regarded as a foreign matter and to be discharged from the foreign matter discharge port 13.

As described above, by controlling the screw 3 in the normal and reverse directions, it is possible to provide a dust supply device having a foreign matter selection function.

Further, since the two screws 3 are separately and independently driven by another driving device, even if one screw 3 has a defect or a failure, the other screw 3 can be continuously driven, It can be operated efficiently.
