Abstract
The present invention relates to a method for threshing and harvesting before cutting and a device thereof. Crops are inclined backward under the poking action of a rice lifter. The ear parts of the crops are guided by a feeding belt which moves backward to move backward further, and are fed and threshed under the action of a belt movable concave board and bow teeth of a roller and the suction of strong air currents. Threshed grains are sent to an inertial separating box. The air currents enter a blower fan through a pipeline above a baffle board after turning suddenly in the separating box, and then the threshed grains are exhausted. The crops and impurities are ejected by the inertia to impact the rear wall of the separating box, and then the crops and the impurities fall. The crops and the impurities are conveyed to a discharging impeller, and are exhausted to enter a threshed grains processing device to carry out grain separating and rethreshing. The separated grains and the impurities are sucked and conveyed by the inclined rising air currents, and then the light impurities are sucked and conveyed out by a transverse current inner machine.
Description
A kind of grain harvest method and machinery.
Traditional cut flow roller combine is generally adopted in rice harves, promptly cuts threshing then earlier, and this method harvesting rice grain broken shell, broken serious can not be made seed usefulness, also is unfavorable for storage.Rice straw damages numerous and disorderly in threshing course, and bigger separation losses is arranged during moist the results.
The axial-flow type drum combine separates loss when the crop high humidity bigger, has to high stubble results usually, and the rice straw damage is serious, twist into straw band during high humidity, and the threshing power consumption is big.
Can avoid above-mentioned shortcoming when clamping semi-feeding type combine is received paddy rice, but the work width of cloth is narrower and be difficult to do significant increase, it is not high to pretend industry efficient; Because mechanisms such as ceding of Taiwan conveying, middle conveying, clamping threshing conveying and feeding depth adjusting are arranged, and the reliability of complex structure, cost height, machine is difficult for improving.
Be the miniature combine that partly feeds that upright results transport courses designs by the rice wheat, its mechanism obtains simplifying, but the work width of cloth and operating speed are less, enlarge difficulty, and efficient is not high.
In the another kind of diverse method aspect results paddy rice and the wheat is exactly threshing prior to cutting.This kind harvest machinery and technology were done a large amount of explorations both at home and abroad, but the type appearance as the receipts paddy rice of commodity was not arranged so far.Belong to real scheme and mainly contain three major types through field trial:
1. belt sheller unit: its feeding mouth can fall lowlyer, suitable receive the big crop of fringe width of cloth difference, but or do not have the measure of blocking grain because of threshing band top and lose and excessively (see Fei Liebin: International Rice Research Institute: " paddy rice threshing prior to cutting combine 1969,1970,1971,1972 annual reports "." Paddy Stripper Combine ", The International Rice Research Institute, Annual Report 1969,1970,1971,1972); Or because of adopting straw shift wheel to make pace be restricted (" exploratory development of threshing prior to cutting paddy rice combine main working parts ", Jiang Yiyuan etc., " agricultural mechanical journal " 1981 1 phases).
2. pneumatic drum type: take off under it divides again formula and on take off two kinds of formulas.Under take off the strain of formula person's standing grain and guide cylinder into by feeding band, only grasp the fringe head later on and realize feeding with the drum threshing tooth, so feed not really reliably, lose greatlyyer, the stem stalk will change very big angle frangibility at feeding mouth when sheller unit is extracted out in addition.(as French Patent (FRP) Aold NO.1272506,21,08,61 reach " experimental study of arch dental roller formula Thresher used before stalk cutting " Jiang Yiyuan etc., " Dongbei Agricultural College's journal " 3 phases in 1988).
On take off formula person and divide two kinds again: one has the feeding of feeding band guiding fringe head for bow tooth threshing cylinder the place ahead, there is a fixing notch board top, between feeding mouth place feeding band and notch board, a slit must be arranged, in this slit with regard to embedding that short grass and disconnected fringe etc. are arranged and cause the obstruction of feeding mouth, have a strong impact on normal operation (" QF-110 threshing prior to cutting combined harvester is successful from one's very first attempt ", accompanying drawing 16, is seen at " agricultural machinery intelligence data " the 3rd phase in 1979 in kind pig farm, Hangzhou).
The majority that the Soviet Union is studied for many years is not for establishing the pneumatic drum type of feeding unit, adopt the threshing tooth of double-edged fine-toothed comb formula or Brush type, tassel passes through in the narrow slit of the threshing between cog that horizontally-arranged is arranged, its both sides are subjected to the clamp effect simultaneously and are smoothed out with the fingers and take off, and cause a large amount of disconnected fringe (accounting for 15-40% in the emersion object) and a large amount of long and short stem stalk and broken leaves.It is huge that this just has to that structure is set, complicated disconnected fringe separates and mechanism such as takes off again: (∏ .A Sha Bangnuofu, " with station stalk threshing method (being threshing prior to cutting) results paddy rice " socialist agriculture's mechanization is with electrified, " 1977.8 y б о р к а р и с а м e т о д о м о ч e с а Н а К о р н ю ", П.

Taking off second kind of formula on the cylinder aspiration is with for replace feeding with horizontal rice-pulling chain, crop is divided into little row guides threshing cylinder into, each little row is another afterwards is divided into two, and they are carrying out threshing by drum shaft in traversing process, but its significant drawbacks, said as development person: " passage is narrow again for flow process more complicated; straw will be through twice minute standing grain, a right-angled bend; crop is in case retardance; follow-up standing grain fringe is just crowded, makes some not take off the standing grain fringe and is deposited in the passage by tear fracture, so that stop up.The tender and lovely place of Here it is this threshing process has influenced its practical value ".(" improving the preliminary discussion of thresher threshing ability ", Zheng Weiyi, " the academic nd Annual Meeting collection 1982 of agricultural machinery association results processing equipment " paper original text)
3. the drum-type of not having aspiration: as the threshing cylinder of band saw tooth plate, it is contained in the place ahead of auger in the traditional combine ceding of Taiwan, gullet plate is pulled apart whole tassel at root when cylinder rotates up, throwing under the help that does not have aspiration in the ceding of Taiwan auger, later operation and used mechanism and traditional combine identical, (see BP " crop harvesting apparatus and method ", the application number that " crop Harvesting apparatus and methods " Ind Pat.Appl.PCT/WO 86/01972.153 and same patent are applied for a patent in China is CN861 02434A).Because of no aspiration, grain loss is big (sees N.G.Lucas: " seven kinds of processing methods of results back straw ", power agricultural 1986.12.P.22-24 goes up so-called: one of shortcoming of this machine is that many grain of taking off when the ripe crop of harvest fail to enter the cereal hoisting equipment, " Seven Ways with straw " Power Farming 1986.12 " One disadvantage of this stripper header was that in ripe crops the reel(or stripper rotor) threshed out a lot of grain which then refused to travel up the crop elevator "), also having 50% cauline leaf of reaching to be smoothed out with the fingers when receiving wheat in the later stage takes off, increased the load (" A New Stripping Header for combine Harvesters " of subsequent handling, W.E.Klinner etc., " Agricultural Engineer " 1987.Spring).Similarly Soviet Union patent of invention A.C.1165278 cccp, AO1 Д 41/08 NO.3633051/30-15 " y с т р о й с т в о д л я о б м о л о т а с e л ь с к о х о э я й с т в e н н ы х к у л ь т у р н а к о р н ю " still arranged.
4. rectangular tooth comb comb formula, that narrow slit is arranged is smoothed out with the fingers the fringe device: it is fixed on the machine, and the crown of rectangular tooth inserts in the wheat during work, and narrow slit is smoothed out with the fingers the root of tassel disconnected, and what take off is that whole tassel is transported to threshing in the sheller unit of back.This reaping machine is once produced in Australia and was used, but only be fit to rarer, the dry harvesting wheat of production density, and loss bigger, cross the results of paddy rice from not test (N.T.), in Europe and America all do not test and must promote.(G.R.Quick etc.: " cereal harvesting machinery ", American Society of Agriculture Engineers publishes 1978, " The Grain Harvesters ", 1978 ASAE Publication).
To sum up said, threshing prior to cutting is received paddy rice and remained in following problem so far: majority fails to resolve fully the big problem of grain loss during the crop of (1) results non-lodging; What (2) have can not normal operation because of easily stopping up, or emersion object interrupts fringe and the length cauline leaf is too much, has increased the difficulty of subsequent job, and cane breakdown simultaneously is serious, is difficult to do the sideline production raw material; (3) generally can not receive laid crop.
Purpose of the present invention: be that a kind of assurance grain loss of proposition is little, whole-grain harmless and the method for the threshing prior to cutting that the damage of stem stalk is little and neat and the rice harvesting machinery of threshing prior to cutting.
The threshing prior to cutting method that the present invention proposes is that crop recedes under group finger effect of grain lifter, move after the guiding of the feeding band that its fringe portion is subjected to moving backward further, feeding mouth place up to threshing cylinder, the fringe head is feeding and threshing under the effect of moving notch board of belt and bow roller gear and under the suction of powerful air-flow, emersion object by pneumatic transportation to the inertial separation case, air-flow sharp back of turning in case enters blower fan through pipeline above dividing plate, discharge then.Cereal and foreign material are fallen behind the separator box rear wall by inertial impaction, transport on the marker impeller through the belt conveying device, material is discharged from and directly enters the axial flow cylinder-type emersion object treating apparatus that is arranged on the below, emersion object carries out grain at this to be separated and takes off again, grain that separates and light foreign material are through the effect of slantwise updraft, light foreign material are inhaled fortune outside crossflow fan discharge machine, are fallen through auger and elevator by the grain of precleaning and enter tanker or grain sack.
The belt feeding unit that the threshing prior to cutting reaping machine of realizing above-mentioned methods of threshing joins together by grain lifter, with the moving notch board of belt, arch dental roller formula Thresher used before stalk cutting, pneumatic transportation device, inertial separator and the emersion object treating apparatus formed by centrifugal blower and pipeline.
Said grain lifter is the individual profiling grain lifter, comprise left and right two seeding supporting chains in each grain lifter, on seeding supporting chain, fixing the recurved slightly group finger of the taper of evenly arranging, fixing on the drive sprocket axle of seeding supporting chain rear end can dial to refer on the root straw to be extrapolated to dial refer to taper unload the standing grain disk, unload the standing grain disk and covered the root of group finger and only exposed the curved after a while taper of dialling finger, two jiaos have the circular arc profile about the grain lifter base plate rear end.It with the cooperation that dial to refer to the palintrope section under make straw refer to all unload from dialling.Dial curved after a while can the making that refers to the tip and unload and influence with exceeding the function that it provokes the crop of falling the shape smoothly the straw of dialling the finger taper.It is more simple in structure than the grain lifter on the clamping semi-feeding type combine, because dial referring to of the latter is to be connected with bearing pin and seeding supporting chain, dials and refers to realize to unload standing grain and provoke straw under the control of guide rail and slide block.
Walk close to the position of sprocket wheel at seeding supporting chain, between chain and sprocket wheel, put its section and be
The block cover of shape, again perpendicular to the direction of motion of chain, press close to, to block the meshing point that the grain that drops into grain lifter enters sprocket wheel and chain by the edge of facade and the roller of chain perpendicular to the grain lifter base plate for its facade.Thereby prevent grain from being clamped and influence the running of grain lifter.Be fixed on the passive sprocket shaft by the block cover with above-mentioned identical function on the movable sprocket, its facade constitutes an obtuse angle perpendicular to the grain lifter base plate with the chain travel direction.This block cover can move with sprocket wheel when regulating the chain rate of tension, adjusts the act of block cover position when just having saved each adjusting chain rate of tension again.
