The present invention relates to a garbage bag shredding device for preventing safety accidents caused by fragmentation of solid materials.

In general, since household waste, including foods generated in everyday life, greatly pollutes the natural environment in which we live, it is recycled by a certain method or disposed of by incineration or landfill. In order to effectively treat such household waste without incineration or landfill, a process for classifying by recyclable materials or components is required.

The main screening targets for household waste include paper, metals, glass, plastics, food and logistics, and can be selected and recycled for each material. In particular, food and logistics can be resourceized by composting or feed. As such, the method of effectively sorting materials having different properties may be classified by weight, by magnetic force, or by size. The sorting apparatus may be divided into manpower and machine. In this case, as the mechanical method, air screening, magnet screening, screen screening, etc. are used.

Since 1995, most of the waste generated by the waste-based metering system is encapsulated and transported in a waste-based bag that is standardized for 10 l, 20 l, 50 l and 100 l. Accordingly, as a pretreatment step prior to the sorting step for waste sorting, it is essential to open the bag opening process for tearing out the waste pay-as-you-go bag and pouring out the contents. Opening of envelopes is by means of manpower or by mechanical device. However, by means of manpower, the bag shredding device by mechanical operation has recently been widely used and used because of the high cost and low efficiency. have.

In general, a garbage bag shredding apparatus has been attempted to break a bag by rotation of a blade or circular saw blade fixed to a rotating shaft.

Hereinafter, with reference to the accompanying drawings will be described the present invention in detail.

Referring to Figure 2, the present invention is a hopper (5) to which the garbage bag (B) is inserted, a crusher (50) for crushing the trash bag (B) introduced into the hopper 5, and the crusher ( 50 is installed at the lower end of the chain conveyor 60 for conveying the garbage bag (B) introduced into the hopper 5 to the discharge port (7), the breaker 50 is a drive motor 30, the drive A plurality of bending grooves 14 are formed in the plate 12 fixed to the rotating shaft 32 of the motor 30, and the blades 15 are folded in the bending grooves 14 and then repositioned by the return spring 16. Provided is a garbage bag shredding device consisting of the mounted rotating plate (10).

The rotating plate 10 is fixed to the rotating shaft 32 of the drive motor 30 to be rotated so that the blade 15 can be folded, the rotating plate 10 as shown in Figure 3a disc A plurality of bending grooves 14 are formed in the 12 so as to penetrate through the outside, and the blade grooves 15 are mounted on the bending grooves 14 so that the blades 15 can rotate. That is, as shown in FIG. 3b, the first bracket 17 is fixedly installed in the bending groove 14 of the plate 12, and the first bracket 17 and the blade 15 are fastened to be assembled / disassembled. The member 18 is engaged so that the blade 15 can rotate left and right (as seen in FIG. 3B). The second bracket 17 'is fixed to the plate 12, and the distal end portion of the blade 15 and the second bracket 17' are fastened to the return spring 16. In FIG. 3A, ten blades 15 are mounted. And the drive motor 30 to adjust the amount of processing properly by using a controllable rotation speed, the blade 15 is coupled to the fastening member 18 that can be assembled / disassembled, easy to replace Do it.

Accordingly, the blade 15 bursts the incoming garbage bag B by rotation (breaking), and when a solid material such as a glass bottle or metal touches, only the bag is broken and folded in the opposite direction of rotation, and then the solid material is broken. When it passes, it returns to its original position (restored) by the return spring 16.

Therefore, the breaker 50 according to the present invention completely breaks only the incoming garbage bag B, and does not damage the blade 15 or the solid material, and does not wind the material such as fibers and wires to overload the device. The condition does not occur.

The crusher 50 and the chain conveyor 60 can easily inflow of the garbage bag B into the inlet 6, and the bag B discharged to the discharge port 7 can have a predetermined angle so as to be completely crushed. It is desirable to achieve this. That is, the breaker 50 may be installed to be inclined to be inclined toward the inlet 6, or the chain conveyor 60 may be installed to be inclined, or all of them may be installed to be inclined as shown in FIG. 2. At this time, when the chain conveyor 60 is installed to be inclined, when the garbage bag B containing moisture such as food is broken, there is an advantage that water can be discharged by natural sedimentation to the discharge port 7.

In addition, a lower end of the chain conveyor 60 is provided with a socket-shaped water collecting tank 70 to accommodate leachate. Leachate received in the sump 70 is discharged to the outside through the drain pipe (75).

In addition, since the waste-based bag is standardized for 10 l, 20 l, 50 l, and 100 l, the bagging machine 50 can be moved up and down so that it can be universally used for the bagging of the garbage bags B of various capacities. Can be designed to For example, the shank copper adjusting means (not shown) may be connected to the ceiling of the housing 8 at the upper end of the driving motor 30.

Preferably, in the construction of the breaker 50, as shown in Figure 2 further comprises a square plate-shaped fixing plate 20 is fixed to the main body of the drive motor 30 on the top of the rotating plate 10 Configure.

This is connected to the inclination control means 80 so that the discharge port 7 side of the breaker 50 is moved up and down.

The inclination adjustment means 80 is a pulley 82 fixed to the side wall of the housing 8, a weight 84 moving up and down, and a rope connecting the fixing plate 20 and the weight 84 , 86), the weight 84 is set appropriately weight so as to move the discharge port 7 side of the breaker 50 up and down as described below the inclination angle of the breaker 50 Adjust The central part of the rotating plate 10 is connected to the fixed shaft 95 by separating the fixed plate 20 from the chain conveyor 60 so as to have a distance approximately equal to the diameter of the 100 l bag, and the discharge port 7 has a capacity of 10 l. The fixing plate 20 is spaced apart from the chain conveyor 60 so as to have a distance from which the garbage bag B can be crushed, and is connected to the inclination adjusting means 80. At this time, the breaker 50 is stopped so that it can not go up any more when the discharge port 7 side is raised to some extent, that is, when the fixing plate 20 is almost horizontal with the chain conveyor (60).

Accordingly, in the case of a 10-l garbage bag B, the bag is completely broken near the discharge port 7, and in the case of a 100-l garbage bag B, it is broken at the central portion of the rotating plate 10 while the chain conveyor 60 is broken. ) Is continuously conveyed toward the discharge port 7 by the forced conveyance of the bag, and as the bag presses the discharge port 7 side of the rotating plate 10, the weight 84 of the inclination adjusting means 80 is lowered. It is completely broken while being conveyed toward the discharge port 7. That is, the weight 84 is lowered when a large-capacity envelope enters, and raises the ejection opening 7 side of the breaker 50, and the envelope exits the ejection opening 7 or the envelope is small in capacity. When it comes in, it is back to its original state.
