Description

Grain collecting device

The utility model relates to the cereal collector that uses on a kind of combined harvester, and it belongs to the agricultural machinery scope, the use when being fit to combined harvester harvester for rice wheat.

Along with agrotechnical continuous development, improved seeds directly apply to large tracts of land production, the per unit area yield of rice wheat improves year by year, make the wheat in area, the middle and lower reach of Yangtze River generally reach 600～700 jin, paddy rice reaches about 900 jin, and present Guilin-2 of producing, Guangxi number, Shanghai-the 2B of last marine products and Shanghai-III type combined harvester, when harvesting, exist entrainment loss to some extent (after the threshing, cereal and straw are clipped together from the grass outlet of threshing cylinder and are thrown away), make a part watch that grain in one's hands is scattering into the field again and wastes.This part cereal that how will be entrained in the straw is collected, and is that many in recent years agriculturists urgently wish a difficult problem being resolved.

The problem of the entrainment loss that the purpose of this utility model exists when being to solve above-mentioned similar combined harvester harvesting.A kind of cereal collector is provided, with it be installed in the combine cylinder grass outlet near, the straw of carrying cereal secretly that throws away from the threshing cylinder grass outlet is separated once through this device again, pack is separated and collected to the cereal of wherein carrying secretly.

Principal character of the present utility model: this cereal collector just is installed near the combine cylinder grass outlet, after not separating the straw of thoroughly carrying cereal secretly and separating through the millet straw separator that is rotating, straw is sent from its end, cereal is fallen in the grain collector after then being separated by the millet straw separator, and grain is collected.

Advantage of the present utility model and economic benefit are extremely significant.The entrainment loss of wheat is 2～4%, the entrainment loss of paddy rice is 3～7%, even 10%, we get its median, wheat 3%, paddy rice 5%, be about 20 jin of every mu of losses of wheat, about 45 jin of every mu of losses of paddy rice, two ripe crops amount to about 65 jin, we absolutely collect cereal after can not guaranteeing to have used the cereal collector, but can accept fully by the grain (promptly 40～50 of two ripe crops jin/mu) of this device back 70～80%.Its advantage is that this apparatus structure is simple, easily install, itself again need not take much funds, be easy to be accepted by the combined harvester driver.To with regard to the attention degree of grain, its social benefit well imagines that the agricultural vocations has just said nothing of with regard to country.

Fig. 1 is the schematic perspective view of the cereal collector that the utility model proposes.

Fig. 2 is that the cereal collector cooperates figure with the position of threshing cylinder grass outlet.

Be described in detail as follows below in conjunction with the concrete structure and the working condition thereof of accompanying drawing the cereal collector:

This cereal collector is made up of millet straw separator 2, grain collector 5 and supporting base 7 and support 6 etc.Millet straw separator 2 is installed on the supporting base 7, and grain collector 5 is fixed on the frame 6.And millet straw separator 2 is to be made of separate gate 4 and tumbler 3 etc.The shape of separate gate 4 can be made cylindrical or conical, 750 millimeters of diameter D=φ 300～φ; Separate gate 4 usefulness grizzly bars or netting are made.Here said grizzly bar, i.e. steel radial on circumferencial direction, it can be made according to the mode of parallel or helical arrangement, and netting can be to intersect knitmesh, prismatic, shape such as square to produce.In a word, separate gate 4 is a cylinder or the cones with many holes (side, circle, prismatic, rectangle, parallelogram or the like).And tumbler 3 is parts that tightly are enclosed within on separate gate 4 upper port or the lower port, it can make belt pulley, sprocket wheel, gear or friction pulley etc., give tumbler 3, rotate by the outside transferring power together with separate gate 4, its rotation speed n=100～500 rev/min, the cereal collector just be arranged on combine cylinder grass outlet 1 near, with horizontal angle α=15 °～75 °, optimum angle α=35 °～55 °;

Grain collector 5 places the below of millet straw separator 2, and it is shaped as semicircle, radius R＞1/2D; Or make funnel shaped, establish a hole in funnel bottom, or below separator 2 big gunnysack of pocket to connect grain good, grain collector 5 is made the container that can collect grain in a word.Grain collector 5 can be made with various materials such as metal, plastics, cloth bag, gunnysack, glass fibre, dermatine, timber.

Its working condition is as follows:

At first with the cereal collector be installed in combine cylinder grass outlet 1 near.The straw of carrying cereal after the threshing cylinder threshing secretly throws away from grass outlet 1, just enter the millet straw separator 2 of cereal collector immediately, under the effect of the millet straw separator 2 that rotates continuously, straw is sent from the end of millet straw separator 2, and cereal is then entered grain collector 5 by 2 separation of millet straw separator.

Certainly at the inwall of millet straw separator 2 some spiral grass guide boards are installed, help to separate and go out grass also not still can not, just remain further test.
