Description
Technical field
The utility model belongs to technical field of agricultural mechanical equipment, relates to
oneplant straw crushing and field-returning machine.
Background technology
Straw-returning can increase soil organic matter content, culture fertility, reduces water and soil loss, increases ability of retaining and conserveing soil moisture, and improves grain yield.Straw-returning can reduce and avoid crop straw burning, environment protection.Use straw crushing and field-returning machine can also be raised labour efficiency by direct for crops straw chopping and returning, reduce peasant's labour intensity, drop into when reducing rural migrant worker.
Still have in actual life and take to burn, be reluctant to carry out the phenomenon of straw chopping and returning, its reason: is that straw chopping and returning takies a large amount of labour, affects results progress, particularly outstanding when running into unfavourable weather.Two is increase power and production cost, and every mu increases cost 40 ~ 50 yuan.Three is that rice straw total crop return difficulty is larger, needs to increase rotary tillage program.Four is that part straw cutting apparatus is pulverized of poor quality, affects second stubble crop sowing.
Utility model content
The object of this invention is to provide a kind of straw crushing and field-returning machine, the performance of straw crushing and field-returning machine is improved, improve the quality of crushed stalk, reduce power consumption, be conducive to stopping crop straw burning, reducing air pollution.
The technical solution of the utility model is: straw crushing and field-returning machine, comprises hitch, case, gear-box, universal joint, transmission case and ground roll.Case is provided with two and is ranked tool rest, has two to be ranked cutter and movable arbor in case.Universal joint is connected with gear-box, and gear-box is connected to movable arbor by transmission case.Transmission case is provided with driving wheel and driven pulley, and driving wheel is connected with gearbox shaft, and driven pulley is positioned at the side of movable arbor, and driving wheel is connected with driven pulley belt.Movable arbor is provided with moving knife, moving knife helical arrangement, and the radial angle of two adjacent moving knife is 60 ° ~ 180 °.Moving knife is y-type structure, is made up of two panels bending blade, and two panels bending blade is bolted on moving knife seat.Stationary knife is riveted on stationary knife seat, and stationary knife is trapezium structure, and the both sides of stationary knife are provided with sawtooth.
Gap between stationary knife and moving knife blade is 1 ~ 2 ㎜.Moving knife on movable arbor is 2 ~ 6 rows.The rear portion of case is provided with bonnet, and case lower front is provided with check apron.The material of stationary knife and moving knife blade is the violent steel of high-carbon.The transmission case side of case is provided with baffle plate, and baffle plate is equipped with strainer.
Power is passed to gear-box by the Power output beam warp universal joint of tractor, movable arbor is made to drive moving knife blade to rotate by the speedup commutation of gear, produce very high rotating speed and kinetic energy, stalk is squeezed in case, and by straw cutting together with stationary knife, repeatedly impact, the effect of tearing etc. until by crushed stalk, crushing straw sheds ground in the wings equably along encloser inner wall under the effect of air-flow and centrifugal force.
The stationary knife of the utility model straw crushing and field-returning machine adopts the trapezoidal sawtooth blade of band cutting edge, and Cutting Drag is little, trapezoidal cutter double-sided belt tooth, increases cutting stalk chance, decreases power consumption, improve straw cutting apparatus operating efficiency.The stalk that sawtooth is larger to the toughness such as wheat, paddy rice tears the ability of cutting by force, improves crushed stalk effect, is conducive to second stubble crop sowing.When pulling down the use of falling face after the wearing and tearing of one side cutting teeth, maintenance of equipment cost is low.
