になつている。 The drive mechanism of this straw cutter is as follows. First, the rotation of the motor 11 is caused by the rotation of the motor pulley 1.
2 is transmitted via a V-belt 13 to a large pulley 15 on a rotating main shaft 14 that supports the rotating blade 9. Next, the signal is transmitted from the small pulley 16 on the rotating main shaft 14 via the V-belt 17 to the intermediate drive pulley 19 on the intermediate drive shaft 18 . Then, it is transmitted from the intermediate drive gear 20 on the intermediate drive shaft 18 to the lower feed roll gear 22 on the lower feed roll shaft 21 that meshes with the intermediate drive gear 20, and the lower feed roll 8 rotates. Further, the sprocket 23 on the lower feed roll shaft 21 is connected to the sprocket 2 on the intermediate support shaft 25 via the chain 24.
6. Then, it is transmitted from the gear 27 on the intermediate support shaft 25 to the upper feed roll gear 29 on the upper feed roll shaft 28 that meshes with the gear 27, and the upper feed roll 7 rotates. Note that the upper and lower feed rolls 7 and 8 are designed to rotate at the same speed. Further, the upper feed roll 7 is configured to move up and down in an arc shape around the intermediate support shaft 25 depending on the amount of material fed.

るようにしてある。 The cutting length of the material is determined by the rotational (feeding) speed of the upper and lower feed rolls 7 and 8. That is,
The rotational speed of the upper and lower feed rolls 7 and 8 is determined by appropriately combining several types of intermediate drive gears 20 and lower feed roll gears 22 prepared in advance, and changing the gear ratio to adjust the rotation speed of the intermediate drive shaft 18 and the lower feed roll shaft. 21, it is possible to adjust the speed change in stages.

る。 Reference numeral 18 denotes intermediate drive shafts for rotating the lower feed roll 8, and two intermediate drive shafts are provided on a circumference D having a predetermined radius R centered on the axis of the lower feed roll gear 22. Of these, the first intermediate drive shaft 18a rotates by being transmitted from the rotating main shaft 14 shown in FIG. The second intermediate drive shaft 18b connects the chain 31 from the small sprocket 30 on the first intermediate drive shaft 18a.
The rotational speed is transmitted to the large sprocket 32 on the second intermediate drive shaft 18b for deceleration rotation.
