Abstract
A wheat straw shredding machine belongs to the mechanical technical field which cooperates with a combine harvester. The utility model provides a wheat straw shredding machine with little power consumption and good cutting performance, which can't be clogged. The utility model comprises a casing, a main axel, cutter blades and a driving device. Engaging lugs are intervally fixed on the circumference of the main axel, and the engaging lugs are hinged with vertical cutter blades. The direction of the cutting edges of the cutter blades is the same to the direction of an entrance of the wheat straw. The utility model is improved as follows: the cutter blades consist of the vertical cutter blades and the transverse cutter blades, and the transverse cutter blades whose direction of the cutting edge is the same to the direction of the vertical cutter blades are dead-jointed in the low end of the vertical cutter blades. The wheat straw shredding machine changes the original straight vertical movable knife to the vertical bending cutter blade and the transverse bending cutter blade with saw-toothed cutting edge, as a result, the cutting performance and the chopping quality of the wheat straw shredding machine are both evidently improved, and the power consumption of the wheat straw shredding machine is reduced. The wheat straw shredding machine can effectively prevent the wheat straw winding in the casing to avoid the clogging, which is specially suitable to be used with the combine harvester. The wheat straw shredding machine can finish the cutting of the wheat and the crushing and the returning of the straw in one time.
Description
Technical field
The utility model relates to a kind of wheat stalk cutter mill, belongs to the field of mechanical technique of using with the combine coupling.
Background technology
Behind the harvesting wheat, keeping somewhere in the long stalk in field to influence summer sowing, summer sowing, and to its thorough removing, not only takes a lot of work, requires great effort, and delays farming season, is unfavorable for rushed planting, robs and broadcast.If at the field on-site incineration, can cause severe contamination to environment.For this reason, in recent years, agricultural machinery industry is developed multiple wheat stalk crushing and returning to field machine successively.Wherein, with the matching used wheat stalk cutter mill of combine, be installed in the stalk outlet place of grain header, its power is taken from the shelling jackshaft or the axial-flow type drum axle of grain header more.Its formation comprises and fixing stationary knife of chopping casing and the moving knife hinged with the cutter mill main shaft, the alternate layout of moving knife and stationary knife, and moving knife and stationary knife are vertical blade of the straight sword of straight knife.Though this cutter mill has compact conformation, advantage easy to use, its power consumption is higher, and it is still inadequate to cut off performance.Especially when wheat stalk is wet, can occur cutting not broken situation, cause wheat stalk to be wrapped on the interior parts of casing, the lighter stops up, influences the normal operation of machine, and weight person causes parts to damage.In view of this, the wheat stalk cutter mill of reply existing structure is improved.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of power consumption is little, to cut off performance good, the wheat stalk cutter mill of clogging can not occur, overcomes the defective of above-mentioned prior art.
It is as follows to address the above problem the technical scheme that is adopted:
A kind of wheat stalk cutter mill, it comprises casing, stalk import and outlet, main shaft, blade and transmission device, the main shaft circumferential interval is fixed with engaging lug, be hinged with vertical blade on the engaging lug, cutting edge towards with the wheat stalk importer to identical, be improved to, described blade is made of vertical blade and horizontal blade, is fixedly connected with cutting edge towards the horizontal blade identical with vertical blade in the lower end of vertical blade.
Above-mentioned wheat stalk cutter mill is connected as a single entity between described vertical blade and horizontal blade, and the two excessively connects for circular arc, also can be broken line and connects, and the angle α of the two is 60 °-120 °.
Above-mentioned wheat stalk cutter mill, described blade shapes is
Shape or
Shape, symmetry are articulated on the engaging lug of main shaft.
For further improving the cut-out new capability of the utility model blade, above-mentioned wheat stalk cutter mill, the cutting edge of described blade are zigzag.
For improving the service life of blade, can be the bilateral cutting edge with insert design.So that behind blade one side edge mouth blunt, change the outfit, continue to use the standby cutting edge of opposite side.
Above-mentioned wheat stalk cutter mill can be designed to the inboard of bottom of shell wallboard the corrugated structure, and the corrugated band is vertical with the Way out of crushing straw.Resistance in the time of can increasing blade chopping stalk like this between wallboard and stalk is in order to further improving cutting quality.
For making power input of the present utility model safe and reliable, described transmission device is the band transmission, and driving-belt is provided with regulating wheel.
For preventing to hurt sb.'s feelings after stalk chopped from discharging and crushing straw is evenly shed in the field, be provided with broken straw baffle plate in the crushing straw exit, baffle plate one end and casing are hinged, and the angular adjustment screw rod of being located on the baffle plate places in the arc regulating tank of casing, and is provided with locking nut.
The utility model changes the vertical moving knife of former straight shape the bending blade of combination in length and breadth into, is equipped with the zigzag cutting edge again, cuts off performance and cutting quality and all is significantly increased, and has reduced power consumption.Simultaneously, behind the removal stationary knife, can prevent effectively that the wheat straw stalk is wrapped in the casing, situation about can't cut even run into too moist wheat straw stalk, atwirl blade can be got it outside casing, and keeps the normal operation of machine, clogging can not occur.The utility model is particularly suitable for and the supporting use of combine, can make disposable wheat harvesting and the straw chopping and returning finished of combine.
