2. Description of the Related Art Collected garbage is generally placed in a polyethylene garbage bag. To separate the bagged garbage into flammable and non-burnable garbage, the garbage must be separated. It is necessary to break the garbage bag in the first stage to release the garbage from the garbage bag and collect the broken garbage bag.

As a device for breaking and collecting the above polyethylene garbage bags, the garbage bags to be transferred are brought into contact with a circulating drive having a number of knives to break the garbage bags, and the garbage bags are released. Some collect plastic bags by wind power.

As the most advanced prior art, a screw conveyor is removed from the structure shown in FIG. 1, that is, it has a partially cylindrical bottom, and a plurality of slits are formed in the bottom at predetermined intervals in the circumferential direction. A hook is hung over at least two endless chains that circulate along the partial cylindrical bottom with respect to the provided housing, and the rod is urged by a torsion spring to fall down when an excessive load is applied. However, there is an apparatus that penetrates through the slit and orbits along the bottom surface of the partial cylindrical body, and tears a garbage bag in the process.

[0005]

However, in the above-mentioned prior art which exists as the most advanced technology, the input garbage bag is reliably broken at first, but the input garbage is directed toward the discharge port. If they do not move properly and stay in the same place and start to stay, the toes of the hooks will not reach the garbage bag, and there is a problem that the bag breaking is uncertain.

[0006] In view of the above problems, the present invention ensures that the bagged garbage is torn, and the opened garbage is reliably sent from the input port to the discharge port. An object of the present invention is to provide a bag breaking and bag removing machine in which waste is reliably collected.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a housing having a plurality of slits provided at a predetermined interval at a bottom thereof, and a part of a peripheral circuit being close to the bottom of the housing. A rod is suspended over at least two endless chains provided, bearings are provided on the rod at intervals corresponding to the slits, hooks urged by springs are attached to the bearings, and the hooks penetrate the slits and form a housing. A bag breaker comprising a bag breaking / removing means passing through the bottom portion, and a screw conveyor provided in the housing so that a peripheral edge does not collide with the hook.
In the bag removing machine, a comb-shaped comb blade is provided on an upper frame of a housing, and a hanging blade is provided on a side surface and a shaft portion of a screw and an inner surface of the housing.

According to the present invention constructed as described above, the garbage bag put into the housing is reliably torn by the hook which passes through the slit provided at the bottom and is hooked by the hook and scraped out of the housing. However, the garbage released from the garbage bag is forcibly moved toward the discharge port by the screw conveyor.

Further, by providing the comb blade and the hanging blade, there is no escape of the garbage bag, the bag breaking effect is improved, and the bag entangled with the screw conveyor is removed.

Therefore, the opened dust does not stay in the housing, and the bag can be reliably broken.

Is provided so that the edge 13 and the hook 10 do not collide with each other, and the rotating shaft 15 is connected to a motor 17 via a rotating force transmitting means 16 such as a sprocket.

It is to be noted that, instead of the screw conveyor having the notched edge, a screw conveyor in which a helical partial wing is attached to a rotating shaft to avoid collision with the hook 10 which rotates can be used. Increasing the size toward the side can improve the dust discharging effect.

In FIG. 2, a line shaft 19 driven by two motors 18 and 18 'via a slip coupling S extends along one longitudinal direction of the housing 1, and sprockets 20 are attached to both ends thereof. A line shaft 19 ′ is driven along the other longitudinal direction of the housing 1, and sprockets 4 are attached to both ends of the line shaft 19 ′.

An endless chain 6 is wound around each sprocket 4, 20 with an intermediate wheel 5 shown in FIG. It should be noted that a dust inlet 22 is provided at an upper portion on the upstream side of the housing 1, a discharge port 23 is provided at a lower portion on the downstream side, and a lid 24 is provided on an upper surface of the housing 1.

Even in the escaped state, the tip of the hook 10 is set to remain in the housing 1 from the bottom 2 having a partially cylindrical shape.
This is because it is necessary to pull the broken garbage bag out of the housing 1.

In FIG. 1, the housing 1 is inclined from the refuse inlet 22 to the discharge port 23 because the opened refuse is easily moved toward the discharge port 23 when the bag is broken. It is not always necessary to incline. Also,
By using a sieve structure at the bottom of the housing, the load on the screw conveyor can be reduced, and the efficiency of breaking and removing bags can be increased.

FIG. 8 shows a means for removing dirt and dust bags entangled with the screw conveyor 12, in which a comb-shaped comb blade 34 is provided on the upper frame, and a portion where the claw collides with the screw is notched. . In addition, hanging blades 35, 36, 37 are provided on the side surface and the shaft portion of the screw, the inner surface of the housing, and the screw shaft to improve the bag breaking effect. In FIGS. 3 and 4, the hook blade 36 'is provided at a portion just before the hook 10 retreats from the slit 3 for more effective bag breaking.

FIG. 9 shows an example in which the bottom portion 2 'of the housing 1 is flat, and the hook 10 passes through a slit 3 provided on the bottom surface. 3 and 4, the hook 10 can pass through the slit 3 provided in the partially cylindrical bottom 2 so that the hook 10 passes horizontally as shown in this figure.

In FIG. 10, a plurality of rotating shafts 15 'are arranged along the bottom surface of the partial cylindrical bottom portion 2, these rotating shafts 15' are connected to each other by a chain, hooks 10 are attached to the respective rotating shafts, and slits 3 are formed. The hook 10 is attached so as to pass through and rotate. This example can also be applied to a flat bottom as shown in FIG. It should be noted that a bag breaking effect can be expected even with a single rotating shaft.

As described above, according to the present invention, the bag filled with dust is reliably broken, and the dust released from the bag is reliably discharged from the inlet to the outlet. Since the garbage bags are continuously sent and do not stay, the garbage bags that are continuously put into the garbage bag are directly hooked one after another and broken, and the broken garbage bags are reliably collected.
