In addition, the cutting crushing feeder unit 10c of the inclined input cutting feeder group 10a presses the work against the first cutter 11a to start cutting and crushing. Next, in FIG. 5C, the inclined feeding / cutting feeder group 10a approaches the acute angle refraction part as much as possible to end the cutting and crushing of the work, and also feeds out to the outside by the feeder group 10e. Next, in FIG. 4D, the cutting feeder group 10d and the feeding feeder group 10e retreat as much as possible, and the inclined feeding and cutting feeder group 10a retreats just below the pedestal 14. Thus, the sap flowing out in the process of cutting and crushing is dropped into the lower storage portion 21 and the cutting pressure of the cut and crushed work is reduced.
The crushed crushing container is discharged and collected directly to a storage box 20 provided outside or via a conveyor (not shown).

In the small container crusher according to the present invention, a zigzag-like passage for a work, which physically makes it impossible to insert a fingertip, is set in the preceding stage of the charging space. Further, in the process of crushing the work, the space between the cutting crushing space and the cutting space is adjusted by rotating the mounting shaft 26a provided on the machine frame 26 as a rotation fulcrum in the direction of arrow A in order to cope with the work clogging. The cause of can be removed. Further, at the time of the adjustment removing operation, the driving source is automatically released from the power source for safety.

[0026]
