The crushing unit 20 is in contact with the lower side of the inlet 12, the cutter unit provided on the first driving unit 22 provided on one side of the main body 10 and the rotary shaft 23 rotated by the power of the first driving unit 22. (24).

The first driving unit 22 may be directly connected to the drive motor, or may be configured to combine a chain, a belt, or a reducer with the drive motor.

The cutters 24 are preferably arranged at predetermined intervals in the axial direction of the rotary shaft 23.

The cutter 24 has curved cutting edges 26 correspondingly formed on both sides with respect to the axis center.

Since the cutting edge 26 is formed in a curved shape, the cutting edge 26 may be cut in a manner of winding waste, thereby increasing cutting efficiency.

The rotating shaft 23 is preferably supported by the rotation is coupled to the body.

Although not shown in the drawings, the rotating shaft 23 may be configured to cut waste entering the center of the rotating shaft 23 facing each other while the pair is disposed to face each other with the cutter 24. In this case, the first driving unit 22 is rotated in a state in which the power of the driving motor is transmitted to the two rotation shafts 23 through power transmission means such as gears, chains, and belts, respectively.

The magnetic force selection unit 30 is formed in the lower main body 10 of the crushing unit 20, and selects the metal material and the recycled material using magnetic force from the crushed crushed waste.

Metal materials are mainly nails, screws, bolts and hinges, and the like, and recycled materials may be mainly wood chips. Wood chips will be used to produce livestock bottom sawdust, feed and compost organic fertilizer.

Magnetic force selection unit 30 includes a guide member 32, a rotating drum 34 and a magnetic body (37).

The guide member 32 guides the grinding waste falling down from the grinding unit 20.

The guide member 32 may be a pair of guide plates that are alternately inclined downwardly toward the upper center of the rotary drum 34.

Since the guide member 32 is staggered, the pulverized waste transported downward may be induced in a downward inclined direction.

The rotary drum 34 transfers the crushed waste conveyed by the guide member 32 by the rotation of the rotary shaft 37 linked to the second driving unit 38.

The second driving unit 38 may be directly connected to the drive motor, or may be configured to combine a chain, a belt, or a reducer with the drive motor.

The outer side of the rotating drum 34 may be provided with a blocking protrusion 36 to help the separation of the attached metal material by blocking the magnetic force of the magnetic body 37 during rotation.

Blocking portion 36 is formed to protrude in the outward direction by a set length on the outer peripheral surface of the rotating drum 34, a pair is preferably disposed symmetrically with respect to the center of the rotating drum (34).

Therefore, the metal material and the recycled material are almost completely separated.

The lower side of the rotating drum 34 is provided with a separating member 39 for separating and guiding the metal material and the recycled material.

Separation member 39 is preferably formed to be slightly biased to the right with respect to the center of the rotating drum (34). This is to prevent the magnetic material from falling into the recycling material collection area as much as possible.

Separation member 39 is preferably formed to be inclined to the metal material collection section.

The main body 10 includes a first discharge passage 40 through which the recycled material moves and a second discharge passage 42 through which the metal material moves.

The first discharge passage 40 includes a filter unit 50 that filters foreign substances of magnetic material or non-magnetic material from recycled material.

The filter unit 50 filters out non-magnetic substance such as a magnetic substance that falls by mistake in the rotating drum 34 or a stone substance introduced into the inlet 12.

The filter unit 50 is accommodated in the first discharge passage 40 in the main body 10 through the entry hole 52 formed at one side of the main body 10 of the first discharge passage 40 and the entry hole 52. And a mesh member 54 which is arranged.

The mesh member 54 may be a mesh fixed to the frame or a punched metal sheet. In addition, the network member 54 can be configured in various ways.

It is preferable to configure various sizes of the through-holes so as to filter out wood chips, which are various sizes of recycled material of the mesh member 54.

A guide rail structure (not shown) may be provided in the first discharge passage 40 of the main body 10 so that the mesh member 54 may slide easily.

One side of the main body 10 is provided with a check window 44 for grasping the filter state of the filter unit 50 provided in the first discharge passage 40 and the rotation state of the rotary drum 34.

The inspection window 44 may be provided above the filter part 50 by a frame that is screwed or bolted to the body 10 as a transparent window such as glass or synthetic resin. Of course, the inspection window 44 can be mounted to the main body 10 in various ways.

The main body 10 is seated and supported by the support member 60.

The support member 60 includes a receiving container 62 which is provided to be receivable to separate and contain a metal material and a recycled material.

Receiving vessel 62 may be provided with a handle that can be held by the operator.

At the center of the receiving container 62 is provided a partition wall for separating metal and recycled materials.

As such, when the product is a normal product in the neck, screws or hinges of the metal material recovered from the container 62, it can be directly recycled, and if broken, recycled as scrap metal.

And, in the case of wood chips from waste wood among the recycled materials, it is to be recycled for the production of livestock sawdust, feed, compost, organic fertilizer.

Therefore, the present invention is arranged in a compact, since the magnetic force selection unit for sorting the metal material by the rotational drive in the lower side of the grinding unit, it is possible to improve the grinding efficiency.

In addition, the present invention is provided with a filter unit in the discharge passage to move the recycled material of the magnetic separation unit to filter foreign matters such as non-magnetic material, difficult to recycle and magnetic materials that are accidentally dropped by mixing with the recycled materials such as wood chips, etc. have.

Although the magnetic separator having the crushing function of the present invention is preferably applied to a power plant, it may be variously applied to other waste treatment fields as necessary.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand.
