Description
Technical field
The present invention relates to the grain threshing in a kind of agricultural machinery and clean machinery, is a kind of exhausting sorting wheat thresher and preparation method specifically.
Background technology
In recent years, in order to adapt to the needs of fixing farm output quotas for each household in the rural area, various small-sized selection by winnowing wheat thresher was shown one's talent; Though characteristics are respectively arranged, all exist such or such shortcoming, representative exhausting formula selection by winnowing wheat thresher; It is made up of frame and the feeding mechanism, crushing thresher structure, Lower Hold, selection by winnowing case, air draft mechanism, the transmission mechanism that are arranged on the frame; Feeding mechanism is arranged on crushing thresher structure the place ahead, and crushing thresher structure bottom is provided with Lower Hold, and Lower Hold is connected with the selection by winnowing case through the air channel; The selection by winnowing case is located at crushing thresher structure top, and selection by winnowing case one end is connected with air draft mechanism.This thresher produces negative pressure through air draft mechanism in the selection by winnowing case, suck up being mixed in husk in the grain, broken tangerine bar, dust etc., and outlet blows out from the tier pole road then, this thresher have separating effect better, characteristics that percentage of damage is lower.But the spout of this thresher air intake is bigger, and Lower Hold also is provided with air inlet, and the wind pumping channle bore is also bigger, so could the foreign material of threshing be drawn in the selection by winnowing case under the very large situation of exhausting dynamics, needs the power of adapted just very big; Many places design air inlet has reduced negative pressure degree in the selection by winnowing case on the selection by winnowing case in addition; Because dust is bigger in the wheat plant threshing course; Form secondary pollution easily, influence separating effect, and selection by winnowing case interior is complicated; Design various plate washers and caused easy formation spiral wind, also influenced separating effect; The lattice-shaped arcuate bottom web area of crushing thresher structure is little; Easy formation pulverized little wheat stalk extruding phenomenon in the threshing bin, and causing pulverizing threshing circle frame changes motionless painstakingly, influences threshing performance; It is not thorough to cause grain to separate with clever chaff, and unimpeded inadequately deficiency when existing crop to advance machine.Yet; The Uygur nationality of our South Sinkiang, the Xinjiang feeding method that always has wheat stalk powder and wheat bran stirring back hello cattle and sheep among the people; Occupied critical positions in this powder of straw Domestic Animal feed; But in the middle of feeding, existing thresher is thicker with the wheat stalk pulverizing, has restricted the utilization of wheat stalk powder feed.
Summary of the invention
The objective of the invention is to overcome the shortcoming of existing thresher, a kind of exhausting sorting wheat thresher is provided, compact conformation; Body is little, and is in light weight, cheap; Charging aperture is less, and artificial feeding is very convenient, and suction draught is less demanding; The power of adapted is little, and can not form secondary pollution and spiral wind, purifies new thresher effective, that separation is more thorough, crushed stalk efficient is high.
The objective of the invention is to realize through following technical scheme:
A kind of can with the exhausting sorting wheat thresher of tractor, comprise frame and be arranged on feeding mechanism, crushing thresher structure, Lower Hold, circular cone bellows, grain displacer, secondary sieve cleaning mechanism, air draft mechanism, the transmission mechanism on the frame.It is right-hand that said feeding mechanism is arranged on the crushing thresher structure; Crushing thresher structure bottom is provided with Lower Hold, and Lower Hold is connected with the circular cone bellows through the air channel, and crushing thresher structure top is the circular cone bellows; Circular cone bellows bottom is provided with the grain displacer; Grain displacer below is provided with the secondary sieve cleaning mechanism, and circular cone bellows caping is connected with air draft mechanism, and said transmission mechanism is arranged on the frame left side.
For alleviating the operating pressure of crushing thresher structure; When giving the feeding of crushing thresher structure, pulverizes for the first time said feeding mechanism; So feeding mechanism is made up of the hinge dragon cutter that is provided with in feeding hopper and the feeding hopper, the flight that wherein cuts with scissors imperial cutter is provided with " 7 " notched cut of symmetry, and " 7 " notched cut was carried out the wheat stalk pulverizing when flight carried out feeding; Cutting with scissors imperial cutter is fixed on the hinge dragon axle; Hinge dragon axle through bearing fixing on feeding hopper, hinge dragon axle with pulverize threshing axle integral production or connect with shaft coupling, hinge dragon axle and pulverizing threshing axle rotate synchronously.
