Abstract
The present invention relates to a threshing and harvesting combined machine before wheat cutting, which is placed in the front of a miniature tractor to form a complete set. Under the guidance of a divider and a winder, wheat is beaten by main threshing cylinders which are longitudinally arranged for threshing; threshed seeds, short stems and ears together enter a re-threshing cylinder for re-threshing. After separation through a concave board sieve, the crushed stems are discharged from the machine; the seeds and a small quantity of impurities enter into a cleaner, the impurities are sucked out by air flow, and the seeds are filled into a bag. Finally, the stems of the wheat are cut off by a disc cutter. The present invention is suitable for operation on a small piece of field, particularly for the mechanized operation of harvesting wheat which is inter-planted with other crops. The present invention has the advantages of little energy consumption, small volume, low cost, etc.
Description
The present invention discloses a kind of small-sized threshing and harvesting combine before wheat cutting.
The technological process of traditional combined harvester harvesting wheat crop is: earlier the wheat stalk stalk is cut off, all import then and carry out threshing in the body, separate, clean, seed puts in storage.At present, people have proposed new harvesting method, i.e. threshing prior to cutting.The crop that combined harvester will stand on ground earlier carries out threshing, separates, cleans, and then cuts off the stem stalk of crop.The stem stalk does not enter in the body in the results process.So people develop the cereal Thresher used before stalk cutting and cereal threshing prior to cutting combined harvester substitutes traditional combined harvester, as the CN1075051A Cining Pre-cutting threshing, classifing, selecting and feeding apparatus, a kind of self-propelled threshing prior to cutting combined harvester that France's publication " BTMZA " is reported in March, 90, and Chinese patent 88106505.6 threshing prior to cutting methods and gas receipts cylinder threshing prior to cutting combined harvester etc., its cereal Thresher used before stalk cutting has adopted pressure-bearing type bow tooth threshing roller structure, therefore when farm work, short to the cereal strike time of standing, number of times is few, the cereal threshing performance is low, the percent of loss height.Advantages such as the combined harvester of this type and traditional comparing have the efficient height, and power consumption is few.This type facility of development are self-powered's self-propelled combine at present, are suitable for large-area crops are carried out harvest operation, and it is big also to exist volume simultaneously, complex structure, the weak point that cost is high.
For fear of above-mentioned weak point, the object of the present invention is to provide a kind of small-sized threshing and harvesting combine before wheat cutting, with 8～12 horsepowers of tractors is mating power, is suitable for the operation of little plot, is particularly suited for the harvesting wheat mechanized of wheat and other crop interplanting mode.Have simple in structure, volume is little, power consumption less, characteristics that cost is low.
In order to achieve the above object, the present invention has adopted following technical measures.
Threshing and harvesting combine before wheat cutting places supporting tractor the place ahead, dials standing grain device, sheller unit, cleaning plant, actuating unit and front jockey wheel and the rear disk cutting knife is formed by a minute standing grain.Of the present invention minute standing grain dialled the standing grain device and comprised that the nearside divider on both sides and the dialing-grain unit of band straw shift wheel are positioned at sheller unit the place ahead.Sheller unit of the present invention is made up of main threshing cylinder, multiple threshing cylinder and the band radian concave grate corresponding with it.The consistent parallel longitudinal direction that is with the direction of machine travel of the axis of two threshing cylinders is arranged.Below concave grate, be provided with spiral conveying and stir cage.Cleaning plant of the present invention is erected in the sheller unit rear portion, form by winnow, scourclean and centrifugal blower, the outlet of winnow and the inlet scoop of centrifugal blower all communicate with scourclean, and disc cutter is made up of two groups of parallel cutting dives, is positioned at the back lower place of sheller unit.
The main threshing cylinder that the top is mentioned is arranged 3～6 plate teeth along axis, and 75～85 bows of helical arrangement tooth, 20～25 spike-tooths also vertically are equipped with the grain barrier plate on main threshing cylinder.
Be embedded with rasp bar on the multiple threshing cylinder parallel with main threshing cylinder, be provided with the spirally-guided bar in the front portion of this cylinder, its length is 250～350mm.
Be equipped with corresponding arc concave grate below main threshing cylinder and multiple threshing cylinder, guiding snail tongue is equipped with in two concave grate junctions, is provided with hairbrush on the concave grate of main threshing cylinder correspondence.
It is coaxial that cage is stirred in the winnow of cleaning plant of the present invention and spiral conveying, and winnow is installed in spiral conveying and stirs cage one end, is made up of four blades and housing, and it is 65～85 ° that the seed of housing goes out the Gu Chu angle of inclination.
Owing to adopted above technical measures, the present invention compared with prior art, advantage is as follows:
1, grain threshing device of the present invention has adopted twin-roll parallel longitudinal arrangement architecture, bend tooth-like threshing cylinder relatively with the pressure-bearing type of mentioning among Chinese patent 88106605.6 and the CN1075051A, long to the grain ear strike time of standing when farm work, often, the threshing performance height, not purifying percent of loss only is 0.03%.
2, the present invention is to carry out in the space of drum protecting plate sealing in field grain threshing process, the seed of taking off is mainly thrown to multiple abdomen grain cylinder by the plate tooth, so the shattering spatter loss is few, only be 0.25%, horizontal bow tooth sheller unit only depends on the bow tooth to carry out threshing in the space of opening wide to field cereal in the prior art, spatter loss is big, generally surpasses 10%.Chinese patent 88106506.6 for solving the spatter loss of seed, has been installed powerful blower fan, with this seed is absorbed, and makes machine bulky, complex structure.
3, favorable working performance of the present invention, grain cleaning rate＞97%, total losses are 1.65%.
4, volume of the present invention is less, and swath is 450～600mm, is suitable for the wheat mechanized harvest operation in little plot or the wheat interplanting plot, and is easy to use.
For further specifying characteristics of the present invention, the embodiment below in conjunction with shown in the accompanying drawing 1 to 6 is described in detail.
