Abstract
The present invention relates to an ear picking combine harvester. An ear picking roller with a tooth picking plate replaces a cutting device of a traditional combine harvester. The ear picking combine harvester adopts a conveying slot, a threshing roller with a rasp bar and spike teeth, a fan used for twice cleaning, a cleaning stir cage, a grain outlet stir cage and other assemblies. The ear picking combine harvester is installed and hung on a small sized wheel tractor body through an assembly of a front supporting frame and a rear supporting frame. The ear picking combine harvester has compact structure and small volume. When the combine harvester carries out combine harvesting operation, only ears of the grains are picked off with stalks in the field. The ear picking combine harvester has the advantages of low energy consumption, high working speed and high efficiency. The ear combine harvester is suitable for harvesting wheat, barley, oats, paddies and other various crops. The ear combine harvester satisfies agricultural requirements.
Description
The present invention relates to a kind of and the supporting ear picking combine harvester of minitype wheeled tractor.
In the last few years, external development to ear picking combine harvester made progress.The eighties mid-term, British agriculture engineering research institute (NIAE) has developed a kind of cereal ear-picking unit, by Britain SRE company this ear-picking unit was applied on the self-propelled combine afterwards, and substituted traditional cutter sweep, and be improved to ear picking combine harvester.The disclosed ear picking type combine of European patent EP 0423789A is exactly to substitute traditional cutter sweep with ear-picking unit, and it is made up of ear-picking unit, grain elevator structure, sheller unit, cleaning plant, power drive system.The fringe cylinder of plucking that ear-picking unit is plucked tooth plate by band is formed, and at the rear portion of plucking the fringe tube helical feed is installed and stirs cage.Conveying is stirred the cage outlet and is communicated with grain ear delivery chute inlet, in the grain ear delivery chute scraper conveyer is housed, and the outlet of grain ear delivery chute communicates with the sheller unit inlet.This ear picking combine harvester compares with the combined harvester that with the tractor is power, and the manufacturing cost height costs an arm and a leg.At present, domestic development more with the matching used grain combine kind of wheel tractor, as Chinese patent 87103115 " with the supporting combine of tractor with small four wheels ", 88107365.2 combines and the patent No. 92111762.0 baby comb type combines etc., although it is different on the structure, but something in common all is provided with the cutter sweep of band cutting bed, so when carrying out the harvest operation of cereal, in traditional harvesting mode, the cereal cane is cut off in choosing, all separate in the input body, power consumption is big again.Especially be power with the minitype wheeled tractor, carry out the combining operation, owing to be subjected to the restriction of power output, operating rate is slow when operation, efficient is low, can not satisfy the requirement of agronomy.
The object of the present invention is to provide reasonable material of a kind of employing and Reasonable Parameters, long service life, simple in structure, energy consumption is low, and operating rate is fast, the efficient height, cost is low, and can satisfy the matching used ear picking combine harvester of minitype wheeled tractor of domestic agriculture requirement.
To achieve these goals, the present invention has adopted following technical measures,
A kind of ear picking combine harvester, by ear-picking unit, the grain ear conveying mechanism, sheller unit, cleaning plant, power drive system is formed, be suspended on the supporting wheel tractor body, ear-picking unit is positioned at wheel tractor the place ahead, threshing and cleaning plant are positioned at the tractor back upper place, the grain ear conveying mechanism is housed between ear-picking unit and the sheller unit, belt pulley by power drive system, belt, sprocket wheel, chain, each parts is connected as one, being positioned at the fringe cylinder of plucking that the ear-picking unit in the place ahead plucks tooth plate by band forms, at the rear portion of plucking the fringe cylinder, spiral conveying is housed stirs cage, the outlet that cage is stirred in conveying communicates with grain ear delivery chute inlet, in the grain ear delivery chute scraper conveyer is housed, the outlet of grain ear delivery chute communicates with the sheller unit inlet that is positioned at the tractor back upper place, it is plucked the fringe cylinder and adopts polyurethane or polypropylene material to make, its leading angle of tooth plate of plucking of rhombus is 20～30 °, the fringe tooth root portion of plucking junction adjacent on two is shaped as circular aperture, hole diameter is 16～30mm, adjacent two hole centre-to-centre spacing are 20～60mm, sheller unit is made up of threshing cylinder and the concave grate and the upper cover plate that are installed in the threshing cylinder bottom, cleaning plant is positioned at the below of sheller unit, it is stirred cage and is formed by fan and spiral cleaning, going out paddy stirs cage and is positioned to clean and stirs cage below, the ear picking combine harvester warp, the front and back support assembly is installed on the wheel tractor machine, and ear-picking unit is connected through the lift arm of elevator system with the tractor hydraulic elevating mechanism.
Described ear picking combine harvester, the front portion of threshing cylinder studs with rasp bar, and rear portion binding tooth, cylinder diameter of beater are 350～450mm, and length is 1000～1300mm, and cylinder rasp bar partial-length is 500～800mm.
Described ear picking combine harvester, the fan of cleaning plant is positioned at the concave grate of sheller unit and cleans a side of stirring cage.
Described ear picking combine harvester, the elevator system of ear-picking unit is made up of pulley, steel wire rope and tractor lift arm, and steel wire rope one end is connected with lift arm, and the other end is connected as a single entity through pulley and forebay.
Advantage of the present invention and effect:
1, compare with the external self-propelled fringe combined harvester of plucking, external model structure complexity, bulky, the cost height; The present invention has substituted outside traditional cutter sweep divided by ear-picking unit, also adopts the scraper conveyer in the delivery chute, is made by the threshing cylinder employing polyurethane and the polypropylene material of rasp bar and spike-tooth combination, acid resistance is good, long service life, and compact conformation, volume is little, and cost is low.
2, the present invention only plucks the fringe head with new harvesting approach and substitutes traditional harvesting mode when work, less energy consumption, and operating rate is fast, and the efficient height especially provides supporting ear picking combine harvester tool for 12-15 horsepower wheel tractor.Solved for a long time because minitype wheeled tractor is subjected to the restriction of power output, the miniature combine supporting with it is when operation, service behaviour and second-rate problem, and busy farming season small tractor as major impetus, can lay down non-busy farming season and make means of transport.
3, the present invention compares with domestic traditional combined harvester, and production efficiency can improve 30～50%, and fuel consumption reduces 7-15%, and total loss rate is not more than 3% when operation, and percentage of damage is not more than 1%, and cleannes satisfy agriculture requirement greater than 90%.
4, the present invention is fit to the results various crop, only needs to install the tooth plate of plucking of different size, just can gather in the crops crops such as wheat, barley, paddy rice, oat, linseed, herbage seed.A tractor serves several purposes has improved the availability of facility.
In order to further specify feature of the present invention,, be described in detail below in conjunction with the represented embodiment of accompanying drawing 1 to 5:
