CN2417680Y - Disc toothed-edge type machine for cutting-up straws and lefting on the field thereof - Google Patents

Abstract

The utility model belongs to the agricultural machinery class and presents the solution especially aiming to overcome the problem of poor adaptability of cutting-up wet straws in the existing machine for cutting-up straws. The machine is installed on a straw discharging opening of a combined harvester, and uses contrarotating circular cutting discs to cut. A plurality of large circular cutting discs, small circular cutting discs, straw teasing wheels and straw guiding plates are arranged on two contrarotating shafts. The power is led out from the combined harvester. The small circular cutting discs and the straw teasing wheels conduct functions of feeding and supporting cut straws, owing to the different contrarotation and linear-speed of the small circular cutting discs and the straw teasing wheels. The sample machine is experimentally proved that the utility model has the characteristics of stable work performance, good quality of cutting straws, strong adaptability and favorable operation.

Description

Disk toothed-edge type stalks crushing machine

The utility model belongs to the agricultural machinery class, is additional on a crop cropper parts, and it is specifically related to the structure of novel straw cutter mill.

The operation of mincing and returning to the field is the problem that needs to be resolved hurrily in China's agricultural production behind the straw reaping of wheat, paddy rice, before, when not resolving the technical problem of straw chopping, people often adopt the method for burning that straw is disappeared on the spot to ruin, burn straw and cause the pollution to air to reach the public hazards that cause fire easily, government gives greatly to pay attention to this problem.Under dry status, shred the straw of paddy rice or wheat not difficult, but gathering in the crops time straw water content about 40%, the toughness that early has its straw of dew night is stronger, not only shred difficulty with existing Straw cutting machine, there is the fault of winding, stifled grass to take place in the time of also, cause left alone without help car to waste man-hour, also reduced operating efficiency.At present, domestic hammer pawl formula crushing and returning to field machine and tractor can be preferably pulverized also field to corn stalk, but it is very big to pulverize the straw difficulty of paddy rice or wheat with it.With Xinjiang--2 type combines are supporting gets rid of the hammer crushing and returning to field machine and also can only pulverize the very low wheat straw of water content, pulverizes powerless really to the straw that water content is high slightly.

The purpose of this utility model is special this programme--the disk toothed-edge type stalks crushing machine that proposes of problem that can not meet the demands to the pulverizing of the straw of the high slightly wheat of water content, paddy rice for the cutter mill that overcomes in the prior art, cutting disc adopts the land version of sheet stamping, it adopts the sliding cutting principle of cutting disc, have the effect that reduces the cutting tool blade angle, thereby reduced cutting power and improved work quality.

By as above design, the disk toothed-edge type stalks crushing machine that this programme provided includes the cylinder blade of toothed-edge type, it is characterized in that its fuselage cover is installed in the straw outlet place of combine fuselage, in machine, arranging toothed-edge type great circle dise knife and the toothed-edge type roundlet dise knife of multi-disc between homogeneous phase to changeing, two groups are installed on separately the axle the blade that changes, two between centers are with intermeshing pinion and gear wheel transmission, the grass of dialling that form of gear tooth is housed between each roundel blade is taken turns, on the axle of dialling between grass wheel and the roundlet dise knife, also be set with the grass guide board that prevents that the straw grass from twining, grass guide board is that the cylinder of a thin-walled has an adjutage at circumferencial direction, the outer end of this arm is fixed on the fuselage, and the power of work is by the belt pulley output of grain header.

In this programme, its fuselage cover is shed tube by the wind-guiding of the hitch of standing part and movable part and is formed, hitch is the thin-wall case that all there is window front and back, the window in the place ahead and the straw outlet of grain header link, the window at rear faces two cutters to changeing, and shedding tube is the thin-wall case that there is window the place ahead and the back lower place, and big disk cutter shaft and roundel cutter shaft all are installed in to be shed on the tube, hitch and shed and use hinge-coupled between the tube, and with the bolt locking of position adjustable.This machine can be provided with two or more sets disk toothed-edge type cuttves to changeing.

Adopt this programme can embody following superiority; 1. this disk toothed-edge type stalks crushing machine has adopted the circular cutter of multi-disc to changeing, the disk diameter difference of two groups of cutters, so linear velocity difference of its cutting edge part, certain relative motion is arranged between the two, the grass of dialling that form of gear tooth also respectively is housed on the axle of roundel cutter is taken turns, large and small cutting disc all is backward with the direction of motion of dialling the relative position of grass wheel, the effect of carrying is backward arranged, because the linear velocity difference between them, the roundlet dise knife is taken turns the effect that the straw that is cut is also had support and support with group grass, has guaranteed the work quality of cutting and grinding; 2. the big disk cutter is finished the task of cutting under higher line speed, under the situation of roundlet dise knife and group grass wheel dual support, straw is sent to the great circle dise knife, according to sliding cutting and the principle of cutting sth. askew, the effect that reduces the cutting edge angle of wedge and reduce cutting power is arranged, can have under the condition of certain water content its cut-out at straw; 3. adopted the grass guide board that prevents the careless winding of straw of new structure, successfully flowed out backward under the guiding of grass guide board through the grass after the cutting of two cutting dives, guaranteed that the work of chopping is carried out in an orderly manner, it is stablized with continuous work and can increase work efficiency significantly; 4. its body shell is made up of two the part institutes of tube that shed that are fixed on hitch on the grain header and movable part, use hinge-coupled between the two, and fix locking with the bolt of adjustable position, can start the operation easily and saving man-hour of fixing a breakdown with shedding tube if meet failure condition; 5. it is simple in structure, stable work in work, good operation and low cost of manufacture, is worth of widely use.
