Abstract
A kind of threshing and harvesting combine before wheat cutting, place supporting small tractor the place ahead, wheat is dialled dialling of standing grain device at minute standing grain and is drawn down, is the strike threshing of the main threshing cylinder of vertical arrangement, and seed of taking off and short stem, fringe is first takes off again with entering multiple threshing cylinder, after concave grate separates, broken stem stalk is discharged from body, and seed and a small amount of foreign material enter cleaning plant, and foreign material are by the air-flow sucking-off, seed can pack, and last wheat stalk stalk is then cut off by disc cutter.The present invention is suitable for the operation of little plot, especially the harvesting wheat mechanized of wheat and other crops interplanting mode.It is few to have power consumption, and volume is little, low cost and other advantages.
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 cane 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 cane of crop.Cane does not enter in the body in the results process.So people develop cereal threshing prior to cutting combined harvester and substitute traditional combined harvester, as a kind of self-propelled threshing prior to cutting combined harvester of French publication " BTMZA " in March, 90 report, and Chinese patent 88106505.6 threshing prior to cutting methods and gas receipts cylinder threshing prior to cutting combined harvester etc.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, place supporting tractor the place ahead, dial 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, be installed on the frame, belt pulley, belt through actuating unit are connected as a single entity, divide standing grain to dial the standing grain device and be positioned at body the place ahead, comprise the nearside divider on both sides and the dialing-grain unit of band straw shift wheel.Sheller unit is positioned at the branch standing grain and dials standing grain device rear, 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 is erect dried sheller unit rear portion, be made up of winnow, scourclean and centrifugal blower, the outlet of winnow and the inlet scoop of centrifugal blower all communicate with scourclean, and two groups of parallel disc cutters are 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.
The present invention and 8～12 horsepowers of tractors, its complete machine length is 3800～4000mm, width is 1500～1600mm, highly is 1540mm～1600mm.
Owing to adopted above technical measures, advantage of the present invention is as follows:
1, with the conventional small wheat combine relatively, the present invention is simple in structure, volume is little, power consumption less, cost is low.
Because the crop cane does not enter sheller unit, the seed of deviating from does not mix mutually with cane, so structurally save the set bulky straw shaker part of traditional combined harvester, has alleviated machine weight, reduces cost, and power consumption is few simultaneously.Because sheller unit only acts on fringe head position, cane and weeds do not enter in the sheller unit, prevent from the plugging fault that causes because of tide temperature cane and weeds from can prolong the activity duration simultaneously, increase work efficiency.
2, compare with threshing prior to cutting combined harvester of the prior art.
A, the domestic and international present threshing prior to cutting combined harvester of developing are self-propelled combine, and the present invention is and 8～12 horsepowers of tractors use, and be simple in structure, volume is little, cost is low.
The threshing prior to cutting combined harvester of b, external development adopts single threshing roller structure, and the cylinder axle head is equipped with blower fan, and the seed of taking off is cleaned under the effect of this blower fan.This machine swath is 1.5 meters, is suitable for carrying out harvest operation in medium and small plot, and the results total losses is 3～4%, grain cleaning rate＞85%, and the present invention adopts the double threshing cylinder parallel longitudinal direction to arrange, and grain cleaning rate is＞97%, and total losses is 1.65%, favorable working performance.
C, Chinese patent 88106505.6 have adopted the pressure-bearing type threshing cylinder, and efficient is higher, but in order to solve the spatter loss of seed, powerful blower fan has been installed, seed has been absorbed, made machine bulky with this, complex structure, and this type is suitable for the harvest operation of rice crop.
3, 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.
