A hopper 52 for introducing a material to be crushed into the upper part of the body 51, a rotary blade 54 rotated by a drive shaft 53 inside the body 51, and a body 51 side for shearing and crushing in cooperation with the rotary blade 54. And fixed blades 55 and 56 fixed to are provided. A screen 57 is fixedly attached to the body 54 in the vicinity of the lower part of the rotary blade 54 and the discharge path 5 through which the crushed material passing through the screen 57 is discharged.
8 is connected to the lower part of the screen 57.

で剪断破砕する機構である(これを「線状破砕」とい
う)。In a conventional single-shaft shearing crusher as typified by FIG. 11 (a), FIG.
As shown in (b), the shearing and crushing is performed when the tip straight portion of the rotary blade 54 approaches and passes the tip straight portion of the fixed blade 55 (56). That is, the conventional one is a mechanism for shearing and crushing between lines (this is referred to as “linear crushing”).
【0005】このような線状破砕では、破砕抵抗が大き
くなり、必然的に消費電力も大きくなる。[0005] In such linear crushing, crushing resistance increases and power consumption inevitably increases.
【0006】なお、図11の回転刃54の刃先54aは
回転刃54と一体になっているので、これが摩耗すれ

の回転刃には着脱自在な刃先が装着されているので回転
刃はそのままで刃先のみ交換すればよい点では経済的で
あるが、刃先が摩耗すれば、その都度、別の新しい刃先
と交換しなければならないものである。Since the cutting edge 54a of the rotary blade 54 shown in FIG. 11 is integral with the rotary blade 54, if it is worn, it is necessary to replace the entire rotary blade 54 with a new one. In this respect, the rotary blade described in Japanese Utility Model Laid-Open Publication No. 47-17267 is economical in that the removable blade is mounted and only the blade needs to be replaced without changing the rotary blade. Then, each time, a new cutting edge must be replaced.

円滑な運転に支障を来している。On the other hand, since the screen 57 provided below the conventional rotary blade 54 remains fixed to the body,
The rotary blade 54 passes through the same position on the screen 57. That is, since the relative position between the screen 57 and the rotary blade 54 does not change, the crushed material easily stays at a certain position, and thus may cause clogging. As described above, since there is no conventional screen cleaning function, smooth operation is hindered.

なっていることにも原因している。Further, since the crushed object includes various miscellaneous things such as household waste and municipal waste generated in daily life, fluctuations in the crushed object cause an overload on a motor driving a drive shaft. And the crusher may stop.
Further, the overload occurs because the conventional crusher has a structure in which all the crushed materials input from the hopper 52 are supplied onto the rotary blade 54 as shown in FIG. It is also due to that.

A hopper 2 for charging a crushed object is provided on the upper part of a body 1 formed in a substantially housing shape. A retaining chamber 3 is formed in the lower body 1, and a pushing device 5 that reciprocates with a driving cylinder 4 is provided in the retaining chamber 3. A crushing chamber 6 is formed so as to be deviated from the center of the hopper 2 and face the staying chamber 3. In the crushing chamber 6, a rotary blade 8 mounted on the periphery of a drive shaft 7 is provided. When the shaft 7 is driven in a chain by the drive motor 9, the rotary blade 8 is moved in the direction of arrow R (FIG. 4).
It is designed to rotate. The stationary blades 10 and 11 before and after facing the crushing chamber 6 are fixed to the body 1 side. A screen 12 having a semicircular cross section is provided along the rotary blade 8 at a lower portion of the crushing chamber 6. This screen 1

Vertical axis 7 of the drive shaft 7 up to the position of the base end 2b on the side of the fuselage 1
The drive shaft 7 is arranged at a position shifted to such an extent that “a” substantially coincides with each other, so that a stagnation chamber 3 for crushed objects is formed inside the body 1 below the lower opening of the hopper 2. ing. The crushed material thrown in from the hopper 2 is temporarily stored in the retaining chamber 3, and the supply of the crushed material is adjusted by a pushing device 5 which can move forward and backward in the direction of the rotary blade 8. It doesn't matter. The pushing device 5 is formed in a long box shape having a front plate 5a whose tip is inclined downward. A driving cylinder 4 is built in the box, and a cylinder body 4a is fixed to the body 1 side. (Fig. 2). This drive cylinder 4
In order to prevent overloading according to the load (current value or electric power value) of the electric motor 9, the pushing speed is increased when crushing is easily performed, and the pushing speed is increased when crushing is not easy. By operating so as to reduce the speed, the pushing amount of the object to be crushed into the rotary blade 8 can be automatically adjusted. Since the pushing device 5 as described above also has the function of a feeder provided in the conventional hopper, the conventional feeder becomes unnecessary.

Is formed as a prism having a square cross section (a shape obtained by cutting a dice in half). The reason why the cutting edge 22 is square is that four corners 22a of the square can be used as cutting blades. The cutting edge 22 is attached by pressing a square surface against the vertical surface 8a, and is fixed by a bolt 23 so as not to rotate. At this time, the head of the bolt 23 is buried in the bolt hole 23b of the cutting edge 22. In addition, from the back of the square cutting edge 22, the holding metal 24 is made of two bolts 2.

The bolts 23 that fix the horn are removed and the other corner 22b that is not worn is rotated by 90 ° to a position where it becomes a cutting blade, and is again fixed to the rotary blade 8 side in the same manner as described above. Such cutting edges 22 are mounted on the periphery of the rotary blade 8 at 90 ° intervals.
