Abstract

The invention relates to a self-propelled spike-combing combine harvester. In the self-propelled spike-combing combine harvester, a method that grain combing is carried out before threshing is adopted, multiple groups of grain combing machines are combined into a row in a parallel manner, before crops (such as rice and wheat) are cut, grain combing is carried out in a grain combing machine firstly, two rectangular cutting plate tracks obliquely stand to clamp the crops, the length of each cutting plate is 3-8cm, grains of the crops are combed down when the tracks operate upwards at high speed, an included angle between the cutting plate tracks and the ground is 45-70 degrees, and mixture of the combed grains, spike heads and the like is conveyed into an upper threshing machine for secondary threshing, thus straws entering into the threshing machine are reduced, kinetic energy is saved and cleaning becomes easier.

Description

Self-propelled comb fringe type combine

[affiliated technical field]:

The present invention relates to a kind of dependence diesel engine is power, has especially adopted first comb grain, the method for back threshing, and harvesting is the self-propelled comb fringe type associating farm machinery of one.

[background technology]:

At present, known homemade grain header all is to be made up of header, shelling parts, whole screen section etc., sends crop (paddy rice, the wheat) integral body under the cutting threshing of to tax grain machine, and then, axial-flow type drum separates whole sieve, cleans foreign material in the seed.

[summary of the invention]:

In order to overcome homemade grain header all is to adopt cutting earlier, and stalk and fringe are first and carry the method for threshing, need many power; Stalk is put difficulty too much in order; The present invention has taked at first comb grain, handles later fringe head and seed mixture through the comb grain and carries out the secondary threshing, and clean purification; Remaining cane is prescinded by cutter again, mainly is applicable to wheat and paddy rice.

The technical scheme that the present invention solves is: one, comb grain machine part, combine (three, four are the most suitable) side by side with comb grain machine more than two, and mainly contain parts such as rice-pulling chain batten tooth crawler belt, screw feeder, conveyer belt rake and constitute.Each comb grain machine is all accomplished comb grain task alone, and two rice-pulling chain bars stretch before machine, and the ground angle is between (50 °-70 °), the stem of plant bar cramp therein; The flexible taper hook of structure on the rice-pulling chain bar, with the crops straw plate tooth crawler belt of dragging on, the part of running has the iron plate capping, iron plate front end handstand triangle downwards when upwards turning round; Triangle stretches forward, and the top crops straw entering comb grain machine of pushing aside of triangle is combed grain, and left and right sides two-ply tooth crawler belt is combed grain therein by crop fringe head-clamp, and is up-narrow and down-wide; Spacing can be adjusted, one side plate tooth crawler belt to toppling over, and the ground angle is between (45 °-70 °); Long (3-8) CM of tooth, the sharp appropriateness of plate tooth inner edge, too sharp meeting is beaten essence with wheat; The crawler belt running speed is more than 1000 meters/minute, and crawler belt is about rectangle (60 * 50) CM, and last axle drives lower shaft and rotates; Crawler belt is running upwards, band seed upthrow, on arc space is arranged; Guarantee that the upthrow seed is not rebounded not return to drop to the ground, plate tooth crawler belt below is the chain of two a plurality of spring clipes, lets crops straw be clipped in wherein; Guarantee that stalk is not inhaled in the comb grain machine, on-streamly let crop in front progressively get into comb grain in the comb grain machine, then; Come out from the back, each comb grain machine comb mixture such as seed down all has screw feeder to stir out to focus on the back, delivered to by the conveyer belt rake and carry out threshing in the thresher of top; And cleaning room screening impurity elimination (annotate: screw feeder conveyer belt rake and thresher or the like are present national grain header common components with back part, are not my innovations, there is no need illustrated in detail).

Two, harvester; This part is formed a row by three, four wheel cutters, and harvester of device behind the comb grain machine is installed in the comb grain machine back lower place; Three arc cutteves are arranged on each disk; Cutter one side has sawtooth, and cutter prescinds remaining stalk when rotating, and is principle not influence following batch of plantation.As need to pulverize, can the stalk that each harvester is cut off be brought together by screw feeder again, carry out pulverization process.

Comb grain machine comb paddy cleanliness: 1, plate tooth crawler belt running speed; 2, plate tooth cutting edge of a knife or a sword tax degree; 3, height of comb grain machine or the like is relevant.

The beneficial effect that the self-propelled comb fringe of the present invention type combine brings is: 1, energy savings; 2, dwindle the structural volume of thresher, cleaning room; 3, clean easily.

Fig. 1, self-propelled comb fringe type combine simple illustration, though figure: 1, rice-pulling chain bar; 2, folder straw chain; 3, plate tooth crawler belt (comb fringe crawler belt); 4, wheel cutter; 5, front-wheel; 6, thresher; 7, screen box; 8, body; 9, tanker, 10, screw feeder.Fig. 2: plate tooth crawler type comb grain machine structure chart; Fig. 3: comb grain machine vertical section structural map; Fig. 4: a wheel cutter part structure chart; Fig. 5: wheel cutter structure chart.

[embodiment and operation instruction]:

In Fig. 1; Crop is pulled over respectively by rice-pulling chain bar 1 in each comb grain machine; Comb grain by plate tooth crawler belt 3, grain header lets the front end of crop cane upper end slave plate tooth crawler belt 3 get into by the cooperation of following folder straw chain 2 in the process of moving in addition; Comb back to the greatest extent comes out from tail end, lefts in cane wheel cutter 4 and prescinds.Mixtures such as seed under the comb are brought together by screw feeder 10; (annotate: parts such as screw feeder, thresher, body, screen box all are present grain header common components to accomplish secondary threshing or the like in the thresher above the conveyer belt rake is delivered to; Be not my innovation, do not have illustrated in detail, excuse me).

According to wheat and paddy rice Different Crop, the rotating speed of grain machine, thresher is combed in adjustment respectively, soakage, and factors such as the sharp degree of plate tooth, thereby decision is in the pure degree of operating process harvesting crop.

Claims

1. a self-propelled comb fringe type agricultural combine is characterized in that: have many group comb grain machines to constitute a row (three, four groups optimum) side by side, before crop (paddy rice, wheat) cutting; At first comb grain by comb grain machine, two plate teeth of left and right rectangle crawler belt is tiltedly standing, and crop is clipped in wherein; Plate tine length (3-8) CM is between crawler belt and the ground angle (45 °-70 °); Fulfil when upwards running up, comb is crop kernel down.Then, thresher carried out the secondary threshing above the first-class mixture of seed ear was delivered to again.
