The present invention relates to a waste shredder which is improved by complementing the problem of a "waste shredder having a rotatable drum capable of dividing", which is registered and registered as a patented invention 10-0933711, The shredder is crushed by the automatic cut into the hopper side through the conveying means and then interrupted between the rotary cutter and the fixed cutter provided in the main body by the rotation of the rotary drum in the main body so that the rotary cutter has a square shape, To a waste shredder having a rotatable dividable drum having a cutter blade in the form of a square so as to allow the cutter blade to adhere to the cutter blade, to engage with the fixed cutter engaged therewith, and to complete the cutting of the waste.

It is well known that the industrial wastes and household wastes are generated in large quantities along with industrial development, and it is becoming important to dispose of these wastes.

In general, wastes such as waste tires, rubber, waste vinyl, synthetic resin, waste wood, food, waste plastics, PCB, etc. are subjected to a process of being recycled, incinerated or buried.

The wastes that are subjected to such a process are bulky and heavy, which makes it difficult to collect and transport the waste, resulting in a considerable disposal cost.

In addition, since it is bulky, there is a problem that the amount of landfill that can be buried in a landfill is limited, and there is a problem that it is difficult to inject into an incinerator when incinerating.

In recent years, utilization of recyclable wastes among these wastes has been increasing, and a shredder is used as a means for finely crushing waste such as incombustible trash or non-burnable rough and large trash to make it easy to distinguish each type of material.

The shredder, which is a shredding device, is used to shred waste such as a telephone product, a construction waste, and a plastic into a small size. For example, the shredded waste plastic product may be a lumpy product such as a bale packed in a substantially cubic shape It is used for the purpose of crushing with fragments of several tens of millimeters and aiming at reuse.

In order to explain the shredder currently used, the description and the drawings described in the prior art based on Korean Patent Registration No. 10-0663760 will be described with reference to the drawings.

In the above-mentioned patent documents, the conventional shredder includes a housing, a driving source, a rotary drum, a rotary cutter, and a fixed cutter.

In the case of the housing, a rotating drum and a fixed cutter are installed. On the upper side, a hopper for introducing the waste is installed. The driving source rotates the rotating drum to transmit the driving force so that the waste is broken. To the rotary drum side.

The rotary drum is rotated by receiving the rotational driving force of the driving source. The rotary drum rotates so that the waste introduced from the inlet may be crushed, and both ends of the rotary drum are rotatably supported by the housing.

The rotary drum is rotated by receiving the rotational driving force of the driving source, and is rotated so as to crush the waste supplied from the inlet.

Both ends of the rotary drum are rotatably supported by the housing.

The rotary cutter includes a body part and a blade part, wherein the body part is fixed on the outer circumferential surface of the rotary drum, and a plurality of blades are formed on the blade part. A plurality of screw holes are formed in the blade portion of the rotary cutter so as to be fixed on the outer circumferential surface of the rotary drum.

The fixed cutter is installed on one side of the housing to arrange the blades so that the cutter of the rotary cutter passes but not the waste, and the blade of the rotary cutter passes between the blade and the blade of the fixed cutter and the waste is broken.

The rotary cutter, which constitutes a conventional shredder having the above-described structure, rotates in conjunction with rotation of the rotary drum, and the waste to be introduced is interlocked with the fixed cutter.

In the shredder, a rotary drum is integrally formed across the housing and a plurality of rotary cutters are provided on the outer circumferential surface of the rotary drum. The rotary cutter is damaged in the process of shredding waste by using the shredder, It is necessary to replace or replace the entire rotating drum or to disassemble the housing in order to replace or replace a part of the rotary cutter, This is being raised.

In addition, in the conventional shredder, when the waste is put in the hopper, that is, the inlet, it is conveyed by one hydraulic cylinder guide which performs linear motion from the inlet, and then enters the main body housing provided with the rotary drum. So that the throughput of waste having different sizes can not but be limited. (Detailed Description: Korean Patent Registration No. 10-0663760)

Therefore, in order to solve the above problem, a rotating drum composed of one body as a whole is divided by a "waste shredder having a rotatable dividable drum", which is registered and registered in the patent application No. 10-0933711, And a rotary cutter is provided on each of the outer circumferential surfaces of the unit drums to form a rotary drum as a whole, and the rotary cutter is arranged in a streamlined manner along the outer circumferential surface of the rotary drum. When the rotary cutter is damaged or the unit drum is damaged The entire unit of the rotary drum can be replaced and replaced without disassembling and replacing the unit drum of the rotary drum as in the prior art. As a result, it is possible to remarkably reduce the overall maintenance work of the shredder and the maintenance cost, Only the unit drum to be replaced can be partially replaced or repaired, The service life of the hopper can be remarkably extended and periodic maintenance can be carried out at a low cost. Thus, the efficiency of shredding of the waste material can be increased and the reliability of the product can be maximized, A plurality of screws are formed in the hopper, and when the amount of the crushed material injected from the hopper is directed to one side and is input into the screw in a large amount or a small amount, active control adjustment can be performed in units of the rotational feed rate of the screw, The screw conveying speed on the side to be mass-fed is decelerated and the overload is interrupted beforehand and the rotational feed of the side screw to be injected is controlled rapidly so that the proper amount of the object can always flow into the rotary drum in the housing, It is not only possible to operate continuously in a state where there is no overload, It is possible to remarkably increase the service life and to manufacture the large shredder since it is not limited to the machining machine tool, that is, the length of the rotary drum. Thus, it is possible to process a considerable amount of waste in a short time .

However, in the prior art described above, the rotary cutter has a shape close to the rhombus, and the vertex portion is directed to the outer surface of the rotary drum. In the case of the fixed cutter corresponding thereto, And it is found that the cutting is performed only at the vertex portion at the time of crushing so that the crushed material can not be completely crushed and the crushed material is washed away in the conveying direction of the screw.

Patent Registration No. 10-0663760 Patent Registration No. 10-0933711

Accordingly, the present invention has been made to solve the problems of the prior art registration No. 10-0933711, which is registered by the cause of the present invention, so that when the crushed material is engaged with the rotary cutter and the fixed cutter and is crushed, So that the shredding efficiency can be improved by originally blocking the movement of the undamaged residue by the screw.

According to an aspect of the present invention,

The hopper 100 includes a hopper 100 and a hopper 100. The hopper 100 includes a hopper 100 and a screw unit 200 connected to the hopper 100. The hopper 100 includes a hopper 100, A plurality of rotary cutters 400 spaced apart from each other on the outer circumferential surface of the unit drum 310 constituting the rotary drum 300 and a housing 500 surrounding the rotary drum 300, A stationary cutter 600 fixed to the inner circumferential surface of the housing 500 for engaging with the rotary cutter 400 and for crushing the waste material and a crushable material crushed by the rotary cutter 400 at the lower end of the housing 500, A waste shredder having a rotatable dividable drum comprising a conveyor transfer part (700) for transfer,

A horizontal surface 311 is formed on the outer circumferential surface of the unit drum 310 and a vertical surface 313 is formed after a curved surface 312 is formed from one side of the horizontal surface 311. The vertical surface 313 is coupled to the horizontal surface 311 and the vertical surface 313, The supporting member 410 has a triangular support portion 410 coupled to the coupling hole 314 of the horizontal surface 311 and is supported by the support portion 410, Shaped cutter 420 coupled with the cutter 314 is equally spaced.

In the case of the shredder according to the present invention, a rotating drum constituted by one body as a whole is divided into unit drums, and a rotating cutter is provided on the outer circumferential surface of each unit drum to form a rotating drum as a whole, So that it is possible to disassemble and replace only the unit drum of the rotary drum without replacing or replacing the entire rotary drum at the time of replacement due to damage of the rotary cutter or breakage of the unit drum , The ease of the overall maintenance work of the shredder and the remarkable reduction of the maintenance cost.

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

A hopper 100 for dispensing waste, a screw part 200 provided at a lower end of the hopper 100, a housing 500 positioned at an end of the screw part 200, A rotary cutter 400 having a rotary cutter 400 formed on an outer circumferential surface thereof, a stationary cutter 600 facing the inner circumferential surface of the housing 300 and fixed in the longitudinal direction, A shredder having a flow in which a lower end of the rotary drum 300 is transported by being dropped by a rotary cutter 400 of a rotary drum 300 and a fixed cutter 600 is conveyed to a conveyor conveying unit 700 having lower ends thereof, to provide.

A plurality of screw parts 200 provided at the lower end of the hopper 100 are arranged in parallel so that the waste introduced from the hopper 100 is guided into the housing 500 at the end side by the screw part 200.

Meanwhile, the motor M for driving the screw unit 200 is configured to be individually controllable.

That is, when the amount of waste to be dispensed into the hopper 100 is biased to one side in the hopper 100 and the waste is excessively introduced into the screw 200 on the side of the plurality of the screws 200, In this case, when the screw 200 is rotated by the same number of revolutions and the waste is conveyed, the excessive amount of the screw 200 , An excessive load is generated, which causes the screw 200 to fail.

In order to solve this problem, the number of revolutions of the motor M is individually controlled by each screw 200. As described above, the number of revolutions of the motor M of the screw 200, The speed of the motor (M) of the screw 200 on the side where relatively little waste is introduced is controlled at a high speed so that the amount of waste flowing into the rotary drum 300 as a whole is uniformly discharged from each screw 200 Respectively.

A detection sensor S for checking the amount of waste to be dispensed from the hopper 100 to each screw 200 is disposed at the lower end of the hopper 100 at equal distances from the screw portion 200, It is preferable to attach them so as to be fixed on the respective positions and control the rotation speed of the motor M by the measurement value recognized from the detection sensor S. [

The waste conveyed by the screw unit 200 includes a rotary cutter 400 that flows into the housing 500 surrounding the rotary drum 300 on the end side and is arranged on the outer circumferential surface of the rotary drum 300, 500 by a fixed cutter 600 fixedly provided on the inner circumferential surface thereof.

As shown in the figure, the rotary drum 300 includes a plurality of divided unit drums 310, each having a horizontal surface 311 as an outer circumferential surface of each unit drum 310, The horizontal plane 311 and the vertical plane 313 are drilled to form the vertical plane 313 and the triangle 314 coupled to the coupling hole 314 of the horizontal plane 311, Shaped cutter 420 coupled to the coupling hole 314 of the vertical surface 313 and being supported by the support portion 410 are equally spaced apart from each other.

Accordingly, the unit drum 310 having such a configuration is coupled to the shaft 320 so that the rotary cutter 400 as a whole as shown in FIG. 4 or 5 is arranged and connected to the rotary drum 300 in a streamlined manner.

The rotary cutter 400 is engaged with a fixed cutter 600 fixed to the inner circumferential surface of the housing 500 and the waste supplied from the hopper 100 is crushed, The waste can not be passed between the fixed cutter 600 and the waste is forcedly guided and fractured between the rotary cutter 400 and the fixed cutter 600 in accordance with the rotation of the rotary cutter 400.

The fixed cutter 600 is fixed to one inner circumferential surface at a position where the fixed cutter 600 is engaged with the rotary cutter 400 in the longitudinal direction of the inner circumferential surface of the housing 500 as described above.

In addition, the fixed cutter 600 is divided in the longitudinal direction like the rotary drum 300 to facilitate maintenance, replacement, and replacement work.

The stationary cutter 600 is formed to have a rectangular cutter groove 610 corresponding to the cutter 420 of the rotary cutter 400 so as to closely mesh with the cutter 420, It is possible to perform cutting and grinding close to each other.

When the waste is crushed due to the close coupling between the cutter 420 of the rotary cutter 400 and the cutter groove 610 of the fixed cutter 600, the wastes are completely broken by bonding in a rhombic shape as in the prior art, It is possible to solve the problem of being conveyed as it is by the conveyance of the screw part 200, even when it is not broken.

The lower end of the housing 500 is opened to form a screen 900 and the conveyor transfer unit 700 is provided at a lower end of the screen 900.

The screen 900 has an arc shape and covers the entire lower end of the rotary drum 300 and has a plurality of hinges 910 provided on the outer circumferential surface of the screen 900, As shown in FIG.

When the present invention having the above-described configuration is used to crush various wastes such as waste tire, rubber, waste vinyl, synthetic resin, waste wood, food waste, plastic waste, PCB, etc., the waste is supplied to the hopper 100 side The waste is linearly fed by the screw part 200 connected to the lower end side of the hopper 100 and the waste is supplied to the housing 500 side.

At this time, as described above, the supply amount of the waste supplied from the hopper 100 to the screw part 200 can not be supplied in a fixed amount for each screw part 200, and the waste may be supplied to one side of the hopper 100 or a small amount of waste may be supplied to the other side The number of revolutions of the motor M of each screw unit 200 is changed according to a signal of the sensor S provided in the screw unit 200 and the waste is transferred to the rotary drum 300 So that an excessive load is not exerted on the screw portion 200.

The wastes to be delivered from the screw unit 200 are separated from each other by the rotation of the rotary cutter 400 disposed on the outer circumferential surface of the rotary drum 300 of the housing 500 and the fixed cutter 600 fixed to the inner circumferential surface of the housing 500, .

As described above, the rotary drum 300 is rotated by the driving motor 810 provided at one side of the shaft 320, and each of the rotary cutters 400 passes the stationary cutter 600 to break the waste, The waste to be crushed is dropped to the bottom of the rotary drum 300.

The cutter 420 of the rotary cutter 400 has a square shape as shown in the drawing and has a cutter blade on the peripheral edge thereof. The cutter 420 is engaged with the cutter 420 of the rotary cutter 400, The fixed cutter 600 having the grooves 610 can obtain the crushed material having the same specifications without generating the waste that the crushed material is crushed by the coupling between the cutter 420 and the fixed cutter 600 .

Therefore, since the undamaged waste is not generated in the waste dropped to the lower end of the rotary drum 300 in this operation, the undamaged waste is dropped to the lower end of the screen 900 and conveyed and discharged by the conveyor conveying unit It is possible to achieve a complete crushing effect even if a separate process is performed again and the crushed waste, that is, the crushed waste according to the standard, is not crushed again after the crushing process.

When the crushing operation is completed or periodic repairing is required, the entire rotating drum 300 is not disassembled in the housing 500, Only the existing unit drum 310 can be disassembled and collected to replace the rotary cutter 400 or to replace or replace the unit drum 310 itself.

In addition, since the fixed cutter 600 is fixed to the inner circumferential surface of the housing 500 in a divided state, when the cutter is damaged, only the fixed cutter 600 can be replaced or replaced.

After the crushing operation is completed, the screen 900 is rotated around the hinge portion 910 by the cylinder 920 so that the lower end of the rotary drum 300 is completely opened to obtain the crushed waste completely crushed .
