Abstract
The present invention relates to a tangential feeding axial-flow threshing separation equipment. Its threshing element adopts short threaded rod-toothed bar combination structure, said short threaded rod is mounted on the threaded rod seat, the toothed bar is positioned at one side of threaded rod seat, its recessed plate adopts grid sieve and punching sieve combination structure, the above-mentioned two structures can be matched with threshing drum so as to implement threshing and separation of crops. Said invention can be used for threshing and separation of several crops of rice, wheat, rape and soybean, etc.
Description
Technical field
The present invention relates to a kind of axial flow threshing separation facility in tangential feeding type of harvest machinery, the seed that is mainly used in various crop such as paddy rice, wheat, barley and highland barley, rape, soybean takes off from fringe.
Background technology
At present, the drum with rasp bars formula that mainly contains sheller unit, nail tooth drum formula sheller unit, the arch dental roller formula sheller unit of harvest machinery installed threshing separator.Drum with rasp bars formula sheller unit generally adopts the monoblock type grid concave plate, is used for cutting the streaming sheller unit more, mainly by the kneading action threshing, threshing is flexible big, and stem stalk degree of crushing is light, and threshing performance is relatively low when getting out of trouble crop, entrainment loss is big, and to moist crop sensitivity, adaptability is relatively poor.Spike-tooth threshing roll cartridge type sheller unit generally also adopts the monoblock type grid concave plate, be used for feeding full type more, as the spike-tooth threshing cylinder that uses on the combined wheat harvester, the patent No. is: CN 2534799, main strike threshing by spike-tooth, the threshing performance height, insensitive to moist crop, the entrainment loss rate is little, and adaptability is better.But the strike effect is strong, and the seed damage is bigger, and the stem stalk is broken serious, and broken stem stalk and assorted surplus are big in the emersion object, have increased cleaning load, makes cleaning loss percentage increase, and cleans clean rate and reduces.The plate tooth can be regarded the spike-tooth of special shape as.Arch dental roller formula sheller unit generally adopts the braiding cylinder greate, is used for half feeding type more, the main threshing of currying that relies on the bow tooth, and the threshing performance height, band handle rate is lower.Japan's half-feeding combine uses this device, and has applied for patent in China, and the patent No. is: CN 1443437A.But this device is to the big crop incompatibility of fringe width of cloth difference, and its supporting clamping convey device complex structure, and cost is higher.The notch board of axial threshing device commonly used has grid screen formula, stamped sieve formula, three kinds of forms of wire gauze sieve formula, and wherein threshing of grid cylinder greate and separating power are the strongest, but the stem stalk is broken serious.In addition, above-mentioned installed threshing separator generally can't just can adapt to the threshing requirement of various crop through simple adjustment.
Summary of the invention
The invention provides a kind of axial flow threshing separation facility in tangential feeding type, satisfied the threshing performance height of installed threshing separator, entrainment loss is little, assorted surplus less in the emersion object,, strong along drum shaft to the adaptability of various working environments to being evenly distributed, just can adapt to requirements such as various crop through simple adjustment.
This device comprises threshing cylinder and notch board, it is characterized in that: threshing cylinder adopts short grain rod-plate tooth composite construction, patterns under short is installed on the rub-bar support, in the side of rub-bar support the plate tooth is housed, form a compound threshing element, this compound threshing element is arranged on the cylinder of threshing cylinder by spiral way, utilize rubbing of patterns under short to realize that the threshing of crop separates with the strike acting in conjunction of plate tooth, be that existing rubbing also has impact in the threshing course, the threshing performance height, entrainment loss is little, the seed damage is less, band handle rate is not high, and stem stalk degree of crushing is light, and percentage of impurity is low in the emersion object; Patterns under short length is 50～150mm, and the plate tooth height is 60～100mm.Separate notch board and adopt grid-punching combining form, leading portion is the grid screen formula, strengthens threshing and separating power, make emersion object even as far as possible along the cylinder axial distribution, the steel wire spacing is pre-small post-large, and back segment is the stamped sieve formula, reduce the threshing ability, segment length ratio in front and back is 1～4.In addition,, can increase by three arc deflectors, better realize the feeding of crop in threshing chamber at threshing cylinder feeding mouth end according to the characteristic of Different Crop.
When getting out of trouble crop, selecting patterns under short length for use is 50～100mm, and the plate tooth height is 80～100mm, and the plate tooth is installed in vertical with the threshing cylinder axis, and near a side of feeding mouth, this moment, grid screen stamped sieve segment length ratio was 2～4; Rash when taking off crop, selecting patterns under short length for use is 100～150mm, and the plate tooth height is 60～80mm, and the plate tooth is installed in the threshing cylinder axis and becomes certain inclination angle, and away from feeding mouth one side, this moment, grid screen stamped sieve segment length ratio was 1～2.
Axial flow threshing separation facility in tangential feeding type threshing performance height provided by the present invention, carry secretly few, the seed damage ratio is low, and stem stalk degree of crushing is light, and short stem and assorted surplus total amount are few in the emersion object, along the axial distribution uniform of threshing cylinder, adaptability to environment is strong, and is through simply adjusting the threshing requirement that just can adapt to various crop, simple in structure, convenient processing and manufacture has fundamentally solved the ubiquitous problem of present installed threshing separator.
