Description

Circular Straw Cutter {Chaff cutter}

The present invention relates to a round straw straw cutter, and more particularly, by automatically cutting the straw straw processed into a cylindrical or hexahedral shape using a band-shaped cutting blade, not only can significantly reduce labor due to straw straw cutting, but also production cost It is an inexpensive round straw straw cutter that can meet the consumer's purchasing needs.

Generally, rice straw refers to stems that have fallen off the rice after the autumn harvest has been completed. These rice straws have been cut to a certain size using conventional soybeans and then mixed with soybean pods and used as food for livestock. However, in the case of cutting rice straw by using soybean, not only the cutting length is not constant, but there is a problem that farmers recklessly use the soybean due to lack of time and labor in farms that raise livestock in large quantities.

Recently, a variety of cutters for automatically cutting rice straw have been developed to solve the above problems. These cutters perform cutting operations by forcibly feeding the straw bales processed into a cylindrical or hexahedral shape to a fixed blade or a rotating band saw.

However, the above-described conventional cutters can cut smoothly the cube-shaped straw bales having a relatively small volume, but it is difficult to cut the cylindrical straw straws usually weighing 400 to 500 kg or more. For example, the fixed blade type cutter has a problem that the work efficiency is lowered and the cost is increased due to the blade replacement because the blade is blunt or damaged due to the coarse straw straw forcibly forced. In addition, there is a problem that the band saw cutter is similarly excessively bent or broken by the straw bales being transported, or the driving of the motor for driving the band saw by the cutting pressure of the straw is stopped.

The present invention has been made to solve the conventional problems as described above, an object of the present invention is to automatically cut the straw straw processed into a cylindrical or hexahedral shape using a band-shaped cutting blade, labor force according to the straw straw cutting Not only can be significantly reduced, but the production cost is low, to provide a round straw straw cutter that can meet the consumer's desire to buy.
