Abstract

Straw-cutter machine designed to cut into pieces green straw and similar materials comprising a horizontal rotor trimmed with blades directed towards the outside, where the rotor rotates between a certain number of aligned fixed blades that play the role of a grid for the materials to be cut during cutting. Said rotor by an open envelope in its upper part and in its lower part so that an opening is formed for the introduction of als materials to be chopped and an opening for evacuation of the pieces cut openings that extend along the entire length of the face trimmed with blades and presenting this machine the following features separately or in combination: A) the introduction opening is connected to the ejector hole of the crankcase of a fan-conveyor intended for transporting the materials to be chopped towards the machine and the edge of the fixed blades is directed downwards in the direction of the ascending side of the rotor; B) the wrapper of the straw cutter has a portion of the wall that extends through an extended arc around the opening of the insert; C) this wall portion has an essentially cylindrical shape and extends towards the outside of the wall of said shell; D) a guide-screen in the introduction opening is adapted to direct the stream of matter to be cut and the air of the fan-conveyor towards said cylindrical portion of the wall; E) the screen-guide that can be set in different angular positions a record; F) the machine is linked to the fan housing by means of an intercalary element and the guide screen is mounted on this interleaving element g) the rotor is driven from the conveyor fan by a belt and the interlayer element is provided with a device to fix the wrapper of the straw cutter to the desired distance of the fan casing to adjust the tension of the belt as appropriate, h) a lateral edge extends through the casing and is located on the path of the movement of the materials to cut before these last reach the fixed blades, each edge is located on a fixed screen, each edge is located on a guide screen that protrudes inside the machine in the vicinity of the contour of the rotor blades: i) the guide screen is formed by an angular element fixed to the internal face of the machine's envelope, j) the screen-guide is constituted by a record that can rotate around its lower edge, k) this rotary record can be adjusted and set at different angular positions, l) the inside edge of the rotary record comprises an upwardly directed rim, m) this rim is superimposed on a support qeu protrudes from the wall of the enclosure of the machine below the fixed blades, n) the screen-guide is constituted by a plate.
