As shown in FIG. 5, the crushing cutter blade 122 is configured such that a hook-shaped impact bundle 123 protrudes at equal intervals of 120 ° so that the waste 300 can be easily broken.

Here, the edge portion of the impact bundle 123 is formed at an acute angle of 30 degrees to 70 degrees, so that a larger pressure can be applied to the edge portion.

When the edge portion is formed at an angle of less than 30 degrees, an excessive pressure may be exerted on the edge portion, and the end portion of the edge portion may be damaged. If the edge portion is formed at an angle larger than 70 degrees The edge portion is sharpened so that the effect of allowing a larger pressure to be applied can not be sufficiently exhibited.

An upper wall 165 is formed between the crusher cutter blades 122 along the direction of the rotation axis 121 of the crusher cutter 120 and a hole 167 is formed in the upper wall 165.

The upper wall 165 is formed to have a height similar to the outer diameter of the breaker cutter blade 122. The center of the upper wall is formed at the height of the rotation axis of the breaker cutter, Is disposed between the blades 122 so as to prevent the hard and large waste from interfering between the breaker cutter blade 122 and the side wall 115 of the hopper 110 to prevent the operation from being interrupted.

That is, when the upper wall 165 is not present, a large amount of waste is interposed between the crushing cutter blade 122 and the side wall 115, so that the operation of the crushing cutter 120 is interrupted due to overload .

By disposing the upper wall 165 between the crushing cutter blade 122 and the side wall 115 as described above, large waste is prevented from being caught between the crushing cutter blade 122 and the side wall 115 Is configured to pressurize the waste with the crushing cutter blade 122 where bulky, hard waste is placed on the sidewall 115, where the edge is formed with a sharp acute angle [theta].

Thus, it is possible to prevent the operation of the crushing and crushing apparatus 100 from being interrupted due to the overloading of the crushing and crushing apparatus 100 due to the trapping of the bulky and hard waste.

When the crushing cutter 120 is subjected to a pressure greater than a predetermined set pressure, the rotating direction of the crushing cutter 120 is reversed so that the hard waste flows from the upper wall 165 to the crushing cutter 120, (122).

If the waste is trapped between the upper wall 165 and the crusher cutter blade 122 and a pressure greater than a predetermined set pressure is applied, it is configured to inform the outside through a visual or audible alarm unit (not shown) .

At this time, the upper wall 165 is formed with an opening 167 passing through the opening 167, so that the waste that has been crushed through the opening 167 flows downward to be dropped downward.

Thus, by making the crushed waste flow more smoothly downward, it is possible to prevent the degradation of the crushing efficiency due to crushing waste accumulation.

The crushing cutter 130 is provided under the crushing cutter 120 and crushes the crushed waste 300 in the crushing cutter 120 to a smaller size. The crushing cutter 130 includes a crushing cutter 120 And a crushing cutter blade 132 provided on the entire surface of the rotating shaft 131. The crushing cutter blade 132 is provided at the center of the rotating shaft 131,

The rotating shaft 131 of the pulverizing cutter 130 is installed to be positioned in the center between the rotating shafts 121 provided to the left and right opposed sides of the shredding cutter 120. One of the left and right sides of the rotating shaft 131 A wheel balance 160 having a predetermined weight is provided to balance the rotation axis 131 and the other end of the rotation axis 131 is connected to the motor to rotate.

6, the grinding cutter blades 132 are rotatably mounted on four shafts provided at equal intervals of 90 degrees on the edge of a rotary cutter disk 135 provided at regular intervals along the rotary shaft 131 It is snowy.

The crushing cutter blade 132 is installed between the rotary cutter disk 135 and the rotary cutter disk 135. In FIG. 6, four shafts are formed at the edge of the rotary cutter disk, However, the present invention is not limited thereto and four or less axes may be provided on the edge of the rotary cutter disk in consideration of the processing capacity of the waste 300 to correspond to the rotary cutter disk So that the number of the pulverizing cutter blades 132 may be four or less or four or more.

The rotation radius of the crushing cutter blade 132 is formed at a predetermined distance from the crushing cutter blade 122 to prevent interference with the crusher cutter blade 122 when the crusher cutter blade 132 rotates.

The pulverizing cutter blade 132 is installed on the front surface of the rotating shaft 131 at predetermined intervals so that the waste 300 passing through the pulverizing cutter blade 132 can be crushed to a size of 50 to 100 mm, The rotational speed of the crusher blade 132 is maintained at 1200 rpm, which is faster than the rotational speed of the crusher cutter blade 122.

A lower wall 155 is formed between the fixed cutter 150 and the cover 140 where the breaking cutter blade 132 is disposed.

Thus, the waste is also crushed by the interaction of the lower wall 155 and the crushing cutter blade 132, and the waste is interposed between the crushing cutter blade 132 and the fixed cutter 150, Is prevented from being interrupted.

In the crushing and grinding apparatus 100, a soil discharge port 170 is formed to be openable and closable at a portion where the stationary cutter 150 is installed.

The waste supplied into the crushing and crushing apparatus 100 often contains soil. When the soil is accumulated on the floor of the area where the fixed cutter 150 is installed, the soil is hardened And becomes firmly fixed.

If the soil is hardened and piled up in the bottom portion as described above, the crushing cutter 130 may be unsteadily stopped.

Therefore, by opening and closing the soil discharge port 170 in the bottom portion, the soil can be discharged from time to time, thereby preventing the soil from hardening between the fixed cutters 150.

The pulverizing cutter 130 is closed by a cover 140 having a snail structure capable of smoothly discharging the pulverized waste 300. The cover 140 of the snail structure moves from the charging port to the discharging port 141 So that the space is widened.

That is, the cover 140 of the snail structure is provided along the outer periphery of the grinding cutter 130, and the cover 140 of the snail structure is disposed at an approximately 3 o'clock to 9 o'clock position (third quadrant from the first quadrant) The waste 300 can be smoothly discharged through the discharge port 141 by the crushing cutter blade 132. In this case,

On the other hand, by making the space width of the cover 140 of the snail structure at approximately 10 o'clock (second quadrant) above the center of the pulverizing cutter blade 132 smaller than the width of the discharge space at the outlet 141 side, It is possible to prevent the waste 300 that has been crushed by the cutter blade 132 from escaping into a gap other than the discharge port 141 as much as possible.
