Description

STRAW CHOPPER-SPRAYER FROM ROLLERS

The invention relates to agriculture, in particular to devices for chopping straw.

A device is known that contains a frame on which a pick-up, a feeder, including feeding and pre-pressing rollers located one above the other and grinding working body, which is a horizontally mounted knife drum, are mounted sequentially. (Sokolov N.V., Kryazhevsky V.L. et al. Straw choppers // Informlistok. No. 74-99 - Kirov, 1999. - 3 pp.).

The disadvantage of this device is the low reliability of the working body and the non-compliance of the particle size distribution of the crushed straw particles with the agrotechnical requirements established for scenting as fertilizer.

Closest to the proposed technical solution, the closest to the proposed technical solution is a KUF-1.8 mower-baler-chopper-loader, containing a frame with a pick-up sequentially located on it, a feeder with feed and pre-pressing rollers, a grinding chamber with an unloading neck, inside of which there is a grinding worker drum type organ, and deflector. (Mower-baler-grinder-loader KUF-1.8. Technical description and operating instructions. - Kiev, 1980. - 70 p.)

The disadvantage of this design is the mismatch of the particle size distribution of the crushed product agrotechnical requirements.

The inventive utility model is aimed at solving the following problem - the compliance of the degree of chopping of straw with agrotechnical requirements established for smelling it as fertilizer.

The problem is solved due to the fact that in the grinder-spreader containing the frame mounted on the chassis, on which the pick-up, feeding device, including feeding and pressing located one above the other, are mounted sequentially

rollers, a grinding chamber with a rotary grinding element of drum type installed in it with the possibility of rotation, an unloading neck and a expandable deflector, an unloading neck of the grinding chamber equipped with vertical dividers of a straw-air note mounted in increments decreasing to the vertical axial flatness of the deflector.

This constructive solution allows the grinding process to be carried out with the required grinding wall due to the fact that the discharge neck of the grinding chamber is equipped with vertical straw-air flow dividers mounted in increments decreasing to the vertical axial flatness of the deflector.

In Fig, presents the proposed chopper-spreader straw from the rolls.

The trailed straw chopper-spreader from rolls consists of a frame 1 mounted on the chassis 2, a feeding device 3, including feed and pre-pressing rollers, a grinding chamber 4, a drum-type working member 5, driven by a tractor PTO through a driveshaft 6 and a gearbox 7 , and dividers 8 of straw-air flow. The working bodies of the pick-up 9 are driven into rotation through a box of 10 speeds. To adjust the width and uniformity of the dispersion of the crushed material, an expanding deflector 11 is used.

Crusher-spreader straw from the rolls works as follows.

When the unit moves along the roll, the straw mass is picked up by a pick-up 9 to the feed and pre-pressing rollers 3, which transport the material to the grinding working member 5. After multi-stage grinding, most of the material with the required particle length passes through the flow dividers 8 and is uniformly distributed using the expanding deflector 11 across the field to the required width. Not passing through the divider 8 along the length of the particles are additionally crushed due to the recycling of the material.
