Abstract
The utility model discloses a threshing device for minisize harvester combine, which comprises a thresher body (6), a thresher cap (7), a grain output packing auger assembly (5) and a threshing rolling drum assembly (8). The grain output packing auger assembly (5) and the threshing rolling drum assembly (8) are positioned inside the thresher body (6); a screen net (4) covered around the lower section of a circular hood threshing rolling drum assembly is positioned on the thresher body (6); a plurality of stubble guide bars (3) are positioned on the thresher cap (7); the screen net (4), the thresher cap (7) and the stubble guide bar (3) altogether form a grain ear threshing and conveyance passage; the inclination angle alpha of the stubble guide bar (3) is controlled within 8 to 8.5 degree; a rolling strip (1) arranged in stage layout is positioned in between nearby stubble guide bars (3). By adopting the structure, the utility model resolves the problem of poor threshing effect and low yield rate, has the advantages of simple and feasible structure, stable and reliable operation, excellent threshing effect, little grain loss and high economic benefit, thus increasing the yield rate by more than 5 per cent.
Description
Technical field
The utility model relates to a kind of miniature combine harvester, and is particularly a kind of from the decline sheller unit of type combine of travelling wheel.
Background technology
Declining from travelling wheel, to have a volume little for the type combine, in light weight, simple in structure, manoeuvrable, convenient transfer, the production efficiency height, price is low, characteristics such as the investment payback time is short, and can be in the mountain area, use freely on the land for growing field crops of the field piece of upper level and hilly country or economic crops interplanting, gathering in the crops efficient simultaneously is artificial 20 times, can solve the seasonal problem of shortage of present rural laborer, and extremely southern mountain area, the peasant household of economic crops such as upper level and hilly country peasant household and northern barley and wheat and cotton interplantings favors, in south and the north all have great market potential.
But existingly in use exist following weak point: when running into the not overripened or more difficult threshing of some kind of crop from the travelling wheel type combine that declines, as the barley and wheat that obstructs the rice or the north is will threshing unclear, directly discharge grain from straw outlet, cause the paddy percent of loss excessive, reduced results efficient, the existence of this problem has restricted from the decline further expansion in type combine market of travelling wheel.For this reason, many scientific research institutions, manufacturer and knowledgeable people have constantly carried out R and D, do not improve way preferably but have as yet so far.
Summary of the invention
Existing for overcoming from the travelling wheel above-mentioned disadvantage that the type combine exists that declines, the purpose of this utility model just provide a kind of simple and reasonable, improvement expenses is economized, threshing is effective, grain loss is few from the travelling wheel type combine sheller unit that declines.
The technical scheme that its technical problem that solves the utility model adopts; it comprises the threshing body; the threshing cover; go out paddy screw feeder assembly; the threshing cylinder assembly; the threshing cover is fixed on the threshing body; going out paddy screw feeder assembly and threshing cylinder assembly is arranged in the threshing body; on the threshing body, be provided with the mesh screen of ring cover threshing cylinder assembly bottom; described thresher is covered with many straw guiding ribs; mesh screen and threshing cover and straw guiding rib are formed grain ear threshing transfer passage; the inclined angle alpha of straw guiding rib is controlled at 8 degree between 8.5 degree, is provided with the bar that rolls of staged distribution between adjacent straw guiding rib.
For make straw can be on grain ear threshing transfer passage smooth delivery of power, the described height that rolls bar is lower than the height of straw guiding rib.
After adopting said structure, the inclination angle of straw guiding rib is controlled at 8 degree between 8.5 degree, has prolonged the time of straw in the threshing body, has just increased the threshing time of grain ear; Roll being provided with of bar and reduce the gap of threshing cylinder threshing tooth tip and threshing cover, increase the friction of grain ear and threshing cover, raising threshing performance is discharged grass outlet after making the straw through threshing again, and the grain loss minimizing is over half; Have simple and reasonable, characteristics such as working stability is reliable, threshing is effective, grain loss is few, business efficiency height, utilization percent can improve more than 5%.

Fig. 3 is the upward view of the utility model threshing cover.
Embodiment
Fig. 1 is shown in Figure 3, specific embodiments for a kind of miniature combine harvester sheller unit of the utility model, it comprises threshing body 6, threshing cover 7, go out paddy screw feeder assembly 5, threshing cylinder assembly 8, threshing cover 7 is fixed on the threshing body 6, going out paddy screw feeder assembly 5 and threshing cylinder assembly 8 is arranged in the threshing body 6, on threshing body 6, be provided with the mesh screen 4 of ring cover threshing cylinder assembly bottom, described threshing cover 7 is provided with many straw guiding ribs 3, mesh screen 4 is formed grain ear threshing transfer passage with threshing cover 7 and straw guiding rib 3, the inclined angle alpha of straw guiding rib 3 is controlled between 8 degree, 8.5 degree, and what be provided with between adjacent straw guiding rib 3 that staged distributes rolls bar 1; The described height that rolls the low dried straw guiding rib 3 of height of bar 1.
The utility model course of work is as follows; straw and grain ear are behind grain ear import input threshing body 6; enter into threshing cylinder assembly 8; between mesh screen 4 and the threshing cover 7; in the moving hand of spiral rotation of covering the straw guiding rib 3 on 7 down along thresher of the threshing cingulum of threshing cylinder assembly 8; make grain ear and mesh screen 4; threshing cover 7; straw guiding rib 3; roll bar 1 generation high-speed friction and carry out threshing; the grain that takes off enters out paddy screw feeder assembly 5 after mesh screen 4 filters; and send from grain outlet by going out paddy screw feeder assembly 5, and straw is discharged from the straw outlet 2 on the threshing cover 7 along the hand of spiral of straw guiding rib 3.
Claims (2)
1; a kind of miniature combine harvester sheller unit; comprise threshing body (6); threshing cover (7); go out paddy screw feeder assembly (5); threshing cylinder assembly (8); threshing cover (7) is fixed on the threshing body (6); going out paddy screw feeder assembly (5) and threshing cylinder assembly (8) is arranged in the threshing body (6); on threshing body (6), be provided with the mesh screen (4) of ring cover threshing cylinder assembly bottom; it is characterized in that: described threshing cover (7) is provided with many straw guiding ribs (3); mesh screen (4) is formed grain ear threshing transfer passage with threshing cover (7) and straw guiding rib (3); the inclined angle alpha of straw guiding rib (3) is controlled at 8 degree between 8.5 degree, and what be provided with between adjacent straw guiding rib (3) that staged distributes rolls bar (1).
