Description
Technical field
The utility model belongs to agricultural machinery technological field, particularly a kind of coaxial line differential threshing cylinder that is used on a rice/wheat combine and the last cereal thresher machine.
Background technology
The technical standard that China formulates has three to the rice/wheat combine transaction capabilities index request under the standard condition, i.e. the total loss rate of seed, percentage of damage and percentage of impurity.Separating mechanism is the core component of three indexs of control, and separating mechanism intermediate roll rotating speed is a principal element.But three indexs are paradox.The threshing linear velocity is low when adopting than the slow-speed of revolution as threshing cylinder, and seed damage is few, and the few seed percentage of impurity of broken stem stalk is low, and threshing is required low in energy consumption, but not net loss increase of threshing; When threshing cylinder adopted higher rotation speed, the result in contrast.Current threshing cylinder all adopts single rotating speed, is three index demands of balance as far as possible, considers as primary factor and will reduce the loss.Therefore, percentage of damage is higher, broken many percentage of impuritys of stem stalk height, and power consumption is big, and operation quality is always undesirable.In order to address this problem, someone has proposed the scheme of conical threshing cylinder, because the radius difference of different normal sections on the cone, under same rotating speed, can obtain different threshing linear velocities, cause not freely easily but move to big end after crop enters from the circular cone small end, notch board and guide plate manufacturing are also complicated; Also the someone has proposed the design of double threshing cylinder, promptly in the position, back upper place that has threshing cylinder now, increase an axial-flow type threshing cylinder that diameter is less again, crop through previous threshing cylinder threshing, throw again and deliver to a back drum threshing, effect is relatively good, but machine volume increases the weight increase; The somebody has proposed the design of current coaxial speed difference double threshing cylinder, though effect is better, exists easily to produce between two cylinders of high low speed and stops up, and another cylinder can interfere and accidents caused weak point when a cylinder produces axial motion.
Summary of the invention
The utility model stops up at easily producing between two cylinders of the existing high low speed of existing current coaxial speed difference double threshing cylinder, the weak point that another cylinder can interfere when a cylinder produces axial motion, a kind of compact conformation is provided, makes simple, reliable operation, can not produce obstruction between two cylinders of high low speed during work, have anti-coaxial line differential threshing cylinder of interfering function.
The technical scheme that the utility model coaxial line differential threshing cylinder adopts is finished in the following way: coaxial line differential threshing cylinder comprises high speed rotary-drum, low speed cylinder, grid-type concave, spiral guide plate and threshing chamber casing, wherein, high speed rotary-drum, low speed cylinder, grid-type concave and spiral guide plate are installed in the threshing chamber casing, are respectively equipped with straw outlet, feeding mouth and seed separating opening at the threshing chamber casing.The low speed cylinder is fixed on the drum shaft by two groups of wallboards, uniform three to six tier pole teeth on the low speed roll circumference, the uniform arrangement of threshing tooth on every tier pole tooth.High speed rotary-drum is fixed on the hollow shaft by two groups of wallboards, and hollow shaft is connected on the drum shaft by two groups of rolling bearings, uniform three to six tier pole teeth on the high speed rotary-drum circumference; Thrust bearing and sealing ring are equipped with in hollow shaft the inner, thrust bearing joins with the cover that is enclosed within on the drum shaft, the another side and the wallboard of cover join, be used to eliminate the assemblage gap of high, low speed cylinder, prevent that two cylinder strings are moving, it is rolling friction that thrust bearing can make the relative motion that causes because of speed discrepancy between two cylinders, and sealing ring can prevent to splash into threshing chamber after lubricating grease from dissolving.The high speed rotary-drum and the low speed cylinder that are installed on the same axle are fixed on the threshing chamber frame by two groups of rolling bearings and bearing block thereof.The low speed cylinder is by being contained in sprocket wheel on the operative clutch axle and driving-chain by being contained in the chain wheel drive on the drum shaft; High speed rotary-drum is by being contained in sprocket wheel on the cleaning fan axle and driving-chain by being contained in the chain wheel drive on the hollow shaft.The low speed cylinder with the high speed rotary-drum junction transition circle is housed, in case crop from the low speed cylinder when high speed rotary-drum moves axially, fall into by the formed spaces of the different cylinder wallboards of two rotating speeds and cause obstruction.
During work, the low speed cylinder rotates with the required minimum speed of rice-wheat threshing, and high speed rotary-drum rotates with the fair speed that rice-wheat threshing was allowed.Taken off crop and seized by the low speed roller rod tooth of quick rotation; formed the rubbing threshing that is hit in the threshing annulus by threshing bar tooth and grid-type concave; and under the effect of spiral guide plate; right-to-left; move axially to high speed rotary-drum from the low speed cylinder; the seed of taking off is thrown to the sorting screen that is positioned at the threshing cylinder bottom through the seed separating opening under centrifugal action; and through the stem stalk after the threshing under action of centrifugal force, radially discharge outside the machine from the straw outlet of high speed rotary-drum end threshing chamber casing.In whole process, 80% above seed coming off on the crop fringe at the low speed cylinder than under the slow-speed of revolution, take off seed and after entering high speed rotary-drum, taken off and remain a small amount of difficulty, thereby preferably resolve seed threshing performance, percentage of damage and percentage of impurity three contradiction, obtain good working performance and operating efficiency.Because design has transition circle and cover, prevented that cylinder from stopping up and the high speed rotary-drum axial motion is accidents caused.
The utility model is compared with existing current coaxial speed difference double threshing cylinder, has compact conformation, makes simple, reliable operation, can not produce between two cylinders of high low speed during work to stop up and anti-characteristics of interfering function.Adopt the utility model can solve contradiction between threshing performance, percentage of damage and the percentage of impurity preferably, have good transaction capabilities index.Use the structure that the utility model does not change original single rotating speed combine threshing chamber, manufacturing cost increases few.
