The axial-flow type roller thresher overcomes the phenomenon that the roller is wound by straw. The thoroughness rate of threshing grains approaches to 100%. The rate of broken grains is reduced to 0.05%. The utility model is suitable for an agricultural harvester.

Description

The axial-flow type type drum thresher

The utility model relates to a kind of axial-flow type type drum thresher, is used for grain header.

Existing grain header generally adopts cut flow roller, and the mode of rolling along tangent line realizes threshing, and threshing is difficult for clean, and the percent of loss and the percentage of damage of grain are big.Application number is 98246213.1, name is called axial feeding axial-flow type drum combine and is furnished with axial-flow type drum in feeding mouth, being provided with semicircular inner walls on cylinder is spiral helicine gathering sill loam cake, on the inwall of feeding hole, be provided with spiral guide slot, this patent application is to now using the improvement of cut flow roller, make the percent of loss and the breakage rate of grain that certain reducing be arranged, but in use straw etc. is wrapped on the cylinder easily, influences work.

The purpose of this utility model is to design a kind of axial-flow type type drum thresher of being made up of spiral feeding blade, spiral guide blade and Lysimachia sikokiana frame for overcoming above-mentioned weak point.

The utility model content:

A kind of axial-flow type type drum thresher, comprise cylinder, blade, bolster assembly and Lysimachia sikokiana frame, it is characterized in that: the cylindrical shell of cylinder is cylindrical, one end of cylindrical shell is a taper barrel, be provided with spiral feeding blade along described circular cone tube surface, be provided with spiral guide blade along cylindrical surface, be provided with the plate tooth, feeding blade and guide blade tandem array at the guide blade top.

The circular cone tube surface of cylinder is provided with fixed head, and feeding vanes screw is loaded on the fixed head.The Lysimachia sikokiana frame by rest pad and

The shape support is formed,

The axle journal at shape support two ends is loaded in the hole of rest pad, and can relatively rotate, and rest pad is welded on the cylinder surface.

Plate tooth on the guide blade is established six and evenly distribution in 360 ° of scopes.

The utlity model has following advantage:

1. because the axial-flow type type drum thresher is provided with spiral feeding blade and spiral guide blade, derive along helical blade, overcome winding cylinder phenomenon, be beneficial to the normal operation of harvester threshing work from the cereal that grain header transports.

2. spiral guide blade top is provided with the plate tooth, and by spiral blade guiding advancing one side threshing, threshing performance almost reaches 100% to cereal on one side, and the grain breakage rate reduces to 0.05%.

3. the utility model is simple in structure, and spiral feeding blade is for removably connecting, and described feeding blade is a consumable accessory, after the feeding blade damages, can pull down fast and change the outfit and go up new feeding blade, is convenient to maintenance, can work on after the of short duration dismounting.

Description of drawings:

Fig. 1 is the utility model schematic diagram;

Fig. 2 is a cross sectional representation of the present utility model:

Fig. 3 is a Lysimachia sikokiana frame schematic diagram;

Fig. 4 is an idler axle constitutional diagram.

Further specify the utility model below in conjunction with drawings and Examples.

Please referring to Fig. 1, Fig. 2, the axial-flow type type drum thresher is made up of Moving plate 1, spiral feeding blade 2, spiral guide blade 4, plate tooth 5, Lysimachia sikokiana frame 7, fixed block 9 and cylinder; Cylinder is made of conical awl tube 3, columniform column casing 6 and drum shaft assembly 8, and Moving plate is welded in the left end of drum shaft assembly, and column casing is loaded on the right of drum assembly, and the awl tube is installed between Moving plate and column casing.Be welded with the fixed block 9 of right quantity on the outer surface of awl tube, fixed block is provided with screw hole, by screw spiral feeding blade is installed on the stator, damages easily because wearing and tearing are big in the spiral feeding blade working, screw connecting mode can easily be changed.Spiral guide blade is welded on the periphery of column casing: spiral feeding blade and spiral guide blade are end to end, and joint requires smooth fluent, and feeding blade and guide blade are twin-feed spiral; The drum shaft assembly is made up of left spindle nose 11, right spindle nose 14, width of cloth dish 12 and tube connector 13, left and right spindle nose is loaded on tube connector two ends and fixing respectively, tube connector adopts hot rolled seamless steel tube, and width of cloth dish is an annular disc, and width of cloth dish is set on the tube connector and welding fixing (Fig. 4); The right-hand member of cylinder is equipped with four Lysimachia sikokiana framves 6; The Lysimachia sikokiana frame is by rest pad 15 Hes Shape frame 16 is formed,

The shape frame is welded into by three round steel, In the hole of two rest pads (Fig. 3), described axle journal can rotate in the hole of rest pad flexibly about the axle journal at shape frame two ends was loaded on respectively, and two rest pads all are welded on the surface of cylinder.The cereal that is transported by grain header during use enters the cylinder left end, when cylinder rotated, cereal just entered and delivers to spiral guide blade part by spiral feeding blade-section, and transmit on threshing limit, limit, the grain of taking off falls into the holder sieve, and the cereal straw is discharged by the Lysimachia sikokiana frame.Cereal-granules all separates with the cereal straw, and discharges smoothly, and the utility model has lowered straw greatly and twined the cylinder phenomenon, and the cereal threshing performance can reach 100% grain crusher rate and also reduce to 0.05%.
