Description
Technical field
The utility model relates to rice wheat harvesting field, especially a kind of grain header being provided with chain type Separation by vibration screen device, can be used for gathering in paddy and wheat.
Background technology
Along with the development of society and the progress of science and technology, level of farming mechanization is more and more higher; All adopt mechanically actuated to realize during current agricultural operation, but for paddy, wheat, its harvesting bucket adopt corresponding grain header to complete; Existing agricultural harvester is of a great variety, and large-scale agricultural cutter, because of bulky, is difficult in uneven Special section operation, and wider road must be had to pass through in addition; Therefore, the rice wheat harvesting bucket of mountain area, knob adopts small-sized harvester for both rice and wheat to complete in recent years, and their basic structure is by existing big-and-middle-sized grain header downsizing, and thus existing small harvester is difficult in mountain area, knob promotes the use of.
At present, the rice/wheat combine on market has semi-feeding type and full feed type two kinds.Half-feed combine harvester is laborsaving comparatively speaking, but price is more expensive, and for fringe difference larger Crop damage can more, and full feed type low price some, and loss lack.Full feed type rice/wheat combine is divided into again crawler type and wheeled two kinds.Substantially all can be used for the results of the crops such as long-grained nonglutinous rice, ratoon rice, hybrid rice, japonica rice, wheat, barley.
But small harvester is easily received by users due to advantages such as volume are little, existing small-sized rice/wheat combine is primarily of the multiple parts composition such as the ceding of Taiwan, delivery chute, threshing cleaning unit, silo, chassis, hydraulic system, electric system.It is as follows in the workflow of farm work: crop is allocated to cutter by straw shift wheel, the crop that cut device is cut off continues by straw shift wheel ceding of Taiwan feeding screw feeder of being pulled over to by crop, by screw feeder, crop is sent into conveying plant, the chain harrow that crop is transferred device is sent to threshing cylinder to carry out threshing and is separated, crop helically moves under the guide plate effect of detachment roller, in motion crop be repeatedly subject to threshing bar tooth and concave grate strike, curry, rub, thus the threshing completing seed be separated.
But, for existing harvesting apparatus, no matter be small-sized rice wheat harvesting equipment or big machinery, the increase of various function makes it become fairly perfect gradually, but for grain header itself, not only to obtain and gather in effect preferably, increase threshing success rate, another very important key factor is exactly point selection operation after being threshing, though existing harvesting apparatus is all provided with independently selection by winnowing and separator, but only be often difficult to reach higher separation requirement by first separation, therefore the effect of existing grain header separation is all poor, need to be improved, make its performance better.
meanwhile, be threshing cylinder is lengthened realize being separated, so segregational load weight in existing grain header; Because threshing cylinder rotating speed is higher, so easily carry paddy, wheat secretly.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of grain header being provided with chain type Separation by vibration screen device at this; This grain header structure is simple, and can improve further on the basis of existing harvesting apparatus and form, compared with existing same device, its improvement is that this grain header adds secondary separation device; Make its paddy that first separation is carried secretly, object that wheat carries out secondary separation; Separator first carries out first separation, carries out second time afterwards and is separated, reach the requirement reducing field loss like this by secondary separation device; Secondary separation device adopts chain type shaker separator to be separated, and load is light, and separation losses is little.
The utility model is achieved in that a kind of grain header being provided with chain type Separation by vibration screen device of structure, and described grain header comprises harvester, threshing band separator, pneumatic separation device; It is characterized in that: described grain header also comprises secondary separation device; Described secondary separation device comprises secondary separation shell, feed auger, chain, chain drive sprocket axle, chain follower shaft, sieve plate, sieve plate shake seat, discharging spiral; Secondary separation shell is provided with material feeding mouth, is separated discharging opening; Described feed auger is positioned at material feeding mouth corresponding position; Discharging spiral lower end arranges described separation discharging opening; Be separated discharging opening corresponding with thrashing cylinder recovery port; The inside of secondary separation shell is provided with chain drive sprocket axle, chain follower shaft; Connected by chain between chain drive sprocket axle and chain follower shaft, drive chain movement by chain drive sprocket axle and chain follower shaft; Chain is provided with multiple sieve plate; The surface of sieve plate has multiple feed separation hole, and the two ends of sieve plate is movably arranged in the latch cylinder on chain, and the lower surface of described sieve plate is provided with the turning end that can roll; Sieve plate shake seat is fixed on secondary separation enclosure, the upper end shape material shaking tooth in a row of sieve plate shake seat; The turning end that described sieve plate is arranged by lower surface and sieve plate shake the material shaking tooth contact of seat upper end, and under chain movement, described sieve plate can be shaken on seat at sieve plate and shake.
