Background technology of the invention There are numerous agricultural purposes whose requirements are met by cutting longitudinal stalks.

For example, cutting a long stalk-like product and distributing it into the soil can reduce the organic matter content. Improve. Alternatively, animal feed food with wheat straw can be finely divided into food preparation mixtures. It is required to be cut into short lengths before being crushed.

A variety of equipped and mobile mixers have been proposed, but most However, it is not practical. The purpose of this is to control the cutting process and to This is because there are difficulties in controlling the transfer of material both before and after. Oh In one particular such machine, described in Stralia Patent No. 591155, A rotary cutter traverses the trailer along with the feed conveyor and discharge chute. This is how it is arranged. A bale lifter protrudes from the rear of the trailer. sharp sides and a wide rattle rod with ends that are rotatably attached to the rotary cutter. , they protrude outward as the cutter rotates, pass between a series of bars, and connect to the anvil. The material reaches further bars which act as a material and advances towards them on a conveyor. It's designed to smash into pieces. Its wide rattle creates airflow. , which pulls the material to be smashed into the cutting area in the longitudinal direction of the output chute. along which the cut material is expelled. This machine is a cutter There is great difficulty in controlling the rate at which material is fed to. It is also packed If the machine is supplied with unpacked materials, the machine will have difficulty unpacking the The cutting action tends to pull the bale over the top of the rotary cutter, resulting in station, eccentrically placed around the rotating cutter to hold down its field and assist in its release. It is necessary to provide rollers mounted with
