Abstract

The utility model discloses a cleaning device of a minitype grain combine harvester, which comprises a threshing machine, a grain thrower, a grain cleaning barrel and a centrifugal fan, wherein the grain thrower, the grain cleaning barrel and the centrifugal fan are arranged at one side of the threshing machine, the grain thrower is sequentially provided with a lower grain throwing tube and an upper grain throwing tube, and the upper port part of the upper grain throwing tube is positioned at the position of the tangent close to the outer side of the upper part of the grain cleaning barrel; abran discharge tube is arranged at the upper port of the grain cleaning barrel and is connected with an air suction tube, the other end of which is connected with an air inlet tube of the centrifugalfan, and the lower part of the grain cleaning barrel is provided with a grain receiving hole. By adopting the structure, the mixture of grain enters into the grain cleaning barrel along the tangentialdirection of the grain thrower; in the grain cleaning barrel, the grain is heavier and falls down along the wall of the barrel so as to be discharged out from the grain receiving hole; bran and chopped grass are lighter in mass and spread in the middle inside the barrel so as to be discharged out by the centrifugal fan through the bran discharge tube and the air suction tube. The device has unique and novel structure, small volume and low cost, and is not easy to be blocked and high in cleaning efficiency, thus having wide popularization prospect.

Description

The cleaning plant of miniature grain combine

Technical field

The utility model relates to the grain cleaning machine of a kind of and miniature grain combine configuration, is particularly useful for the miniature grain combine of 8 ~ 12 horsepowers of walking tractor matching.

Background technology

Crop such as wheat, paddy rice is the extensively crops of plantation of the world.At present about 4.5 hundred million mu of China's annual plantation wheat, about 4.7 hundred million mu of paddy rice, about 80% in Plain wheat mechanized harvest degree, paddy rice about 20%.And lag behind in the mechanization degree development of the vast hills of China, mountain area, intercropping area and economically underdeveloped area, receive level well below the machine in the whole nation.And above-mentioned these the most frequently used farm machinery in area are 8 ~ 12 horsepowers hand tractor, and therefore the development miniature grain combine supporting with it has great significance and act on.Each universities and colleges of the whole nation, agricultural machinery research institute, agricultural machinery manufacturing enterprise have dropped into great amount of manpower and material resources to the research of this respect, have obtained some achievements.Present most cleaning plant has all adopted airstream cleaning device, is down to throw or straight the throwing, and device stops up easily, and cleaning loss is big, and clean rate is low.

The utility model content

The purpose of this utility model provides a kind of maslin that thresher can be separated and thoroughly cleans, and the cleaning plant of susceptible to plugging miniature grain combine not.

The utility model is achieved through the following technical solutions:

A kind of cleaning plant of miniature grain combine, include thresher, grain flinging device, clear grain tube and centrifugal wind, described grain flinging device, clear grain tube and centrifugal blower are placed at a side of thresher, be equipped with down successively on the grain flinging device and throw paddy pipe and upthrow paddy pipe, and the upper port of upthrow paddy pipe is deployed in clear grain tube top tangent position in the outer part; Clear grain tube upper port place is provided with row's chaff pipe, is connected with air intake duct on row's chaff pipe, and the other end of air intake duct is connected with the blast pipe of centrifugal blower, and clear grain tube bottom is provided with and connects the grain mouth.

Be equipped with in the described grain flinging device and advance screw feeder and throw the paddy wheel, throw the paddy wheel and be provided with and throw the paddy blade, describedly throw the front upper place that the paddy pipe is welded on the grain flinging device housing down, be the upthrow formula; The grain flinging device outer end is provided with end cap, and end cap is provided with bearing block and bearing, and an end of described propelling screw feeder places in the bearing, advances the other end of screw feeder to place in the bearing block of installing on another side plate of thresher.

The lower port of described row's chaff pipe places clearly in the grain tube, and its upper port places that the grain tube is outer clearly is connected with air intake duct by anchor ear.

The described grain mouth place that connects is provided with guard ring and sackholder.

The utility model has the advantages that: adopt the utility model, maslin enters clearly in the grain tube along tangential direction by grain flinging device, in clear grain tube, grain is heavier, fall along barrel, discharge chaff and broken careless lighter weight from connecing the grain mouth, diffusion in the middle of in tube is discharged by centrifugal blower by row's chaff pipe, air intake duct.Apparatus structure uniqueness, novelty, volume is little, and cost is low, is difficult for stopping up, and the clean rate height has wide promotion prospect.

Embodiment

As shown in Figure 1, 2, a kind of cleaning plant of miniature grain combine, include thresher 10, grain flinging device 13, clear grain tube 4 and centrifugal wind 11, described grain flinging device 13, clear grain tube 4 and centrifugal blower 11 are placed at a side of thresher 10, be equipped with down successively on the grain flinging device 13 and throw paddy pipe 6 and upthrow paddy pipe 5, and the upper port of upthrow paddy pipe 5 is deployed in clear grain tube 4 tops tangent position in the outer part; Clear grain tube 4 upper port places are provided with row's chaff pipe 3, be connected with air intake duct 1 on row's chaff pipe 3, its upper port places clearly, and the grain tube 4 outer anchor ears 2 that pass through are connected with air intake duct 1, the other end of air intake duct 1 is connected with the blast pipe 15 of centrifugal blower 11, clear grain tube 4 bottoms are provided with and connect grain mouth 8, meet grain mouth 8 places and are provided with guard ring 9 and sackholder 7.

As shown in Figure 3, be equipped with in the described grain flinging device and advance screw feeder 14 and throw paddy wheel 17, throw paddy wheel 17 and be provided with and throw paddy blade 16, describedly throw the front upper place that paddy pipe 6 is welded on grain flinging device 13 housings down, be the upthrow formula; Grain flinging device 13 outer ends are provided with end cap 18, and end cap 18 is provided with bearing block 20 and bearing 19, and an end of described propelling screw feeder 13 places in the bearing 19, advance the other end of screw feeder to place in the bearing block of installing on thresher 10 another side plates.

The sprocket wheel of the power of above-mentioned grain flinging device by advancing screw feeder 13 other ends is by the third wheel transmission that is configured on thresher 10 another side plates; The power of centrifugal blower 11 is by the sprocket wheel transmission of threshing cylinder spindle nose.

During work; promote the maslin that screw feeder 14 separates thresher 10 threshings and shift onto in the grain flinging device 13, be selected into clearly in the grain tube 4 through throwing paddy pipe 6 and upthrow paddy pipe 5 outer tangent line directions down along the front upper place of grain flinging device 13 shells along clear grain tube 4 by the throwing paddy blade 16 of high speed rotating.High speed rotating is gone into the grain in the maslin in the grain tube clearly 4, because quality is heavier, fall along clear grain tube 4 inwalls rotation, flow into sacks by connecing grain mouth 8, chaff and broken grass be because lighter weight, the very fast reduction of rotary speed in clear grain tube 4, diffusion in the middle of in clear grain tube 4, under the effect along with air-flow in the row's of dropping on chaff pipe 3 down,, discharge by the outlet 12 of centrifugal blower 11 at last through row's chaff pipe 3 and air intake duct 1.
