Description

Axial-flow thresher

Technical field

The utility model relates to a kind of agricultural thresher, especially relates to a kind of axial-flow thresher.

Background technology

The axial-flow thresher that present people generally use, the structure more complicated, the threshing effect is bad.Chinese patent; notification number is CN2076309U; the day for announcing is the small-sized thresher of axial-flow type on May 8th, 1991; uniform six roots of sensation tooth bar around it adopts on the cylinder; on the inwall of loam cake, be welded with simultaneously the guide plate that polylith is arranged by certain orientation, this machine threshing performance height, simple in structure, but that this thresher is cleaned is not thorough; be prone to obstruction during threshing, dried cereal is very easily broken.

Summary of the invention

The axial-flow thresher that the purpose of this utility model provides and a kind ofly thoroughly exempts to raise, cereal is not broken, millet straw separates.

The utility model is realized in the following way:

A kind of axial-flow thresher, by frame, charging aperture, main shaft, the cylinder of press strip is housed, screen cloth under the cylinder, inside are made up of loam cake, discharging opening, transmission mechanism and the eccentric stiffener of guide plate, it is characterized in that: this machine inside axially is divided into threshing chamber, separation chamber and suction by two dividing plates successively and penetrates the chamber along described main shaft, the afterbody that the chamber is penetrated in suction is followed successively by chaff discharging port and grass outlet up and down, on the press strip on the cylinder in the described threshing chamber several threshing teeth is arranged; On the described main shaft in the described separation chamber firewood-plucking tooth is housed; Described suction is penetrated on the indoor described main shaft fan is housed; Under the described screen cloth along having a vibratory sieve, the below of its afterbody to have a recleaner screen to link to each other on the described main axis length with discharging opening.

Described dividing plate is a hollow.

Described threshing tooth is distributed on the described press strip, and vertical with its surface.

Described firewood-plucking tooth is " Z " type.

The utility model has following effect:

1) be not easy occur to stop up, seed is difficult for being broken: the axial-flow thresher that the utility model provides, be evenly equipped with the threshing tooth on the press strip on the cylinder in it, and guarantee that crown portion stirs continuously, be not easy obstruction to occur during threshing like this, and seed is difficult for being broken.

2) clean thoroughly; realization exempts to raise: the axial-flow thresher inside that the utility model provides is divided into three chambers; be respectively threshing chamber; the separation chamber; the chamber is penetrated in suction; and by screen cloth; vibratory sieve; recleaner screen is formed screening system; cereal enters from charging aperture; in threshing chamber, take off broken after; by suction penetrate suction that indoor fan produces will thick grass and the big Z type of foreign material in the separation chamber dial the bavin tooth grass fully separated with cereal; and penetrated indoor fan by suction and aspirate out; cereal is separated with thick impurity; cereal under the deposition is fully sieved by three layers of sieve, reaches and thoroughly exempts to raise.

Embodiment

A kind of axial-flow thresher, by frame, charging aperture, main shaft, the cylinder of press strip is housed, screen cloth under the cylinder, inside are made up of loam cake, discharging opening, transmission mechanism and the eccentric stiffener of guide plate, it is characterized in that: this machine inside axially is divided into threshing chamber 2, separation chamber 3 and suction by the dividing plate 20,21 of two hollows successively and penetrates chamber 4 along described main shaft 1, the afterbody that chamber 4 is penetrated in suction is followed successively by chaff discharging port 5 and grass outlet 6 up and down, on the press strip 8 on the cylinder 7 in the described threshing chamber 2 several threshing teeth 9 is arranged; On the described main shaft 1 in the described separation chamber 3 firewood-plucking tooth 10 is housed; Described suction is penetrated on the described main shaft 1 in the chamber 4 fan 11 is housed; Under the described screen cloth 12 along on described main shaft 1 length vibratory sieve 13 being arranged, the below of its afterbody has a recleaner screen 14 to link to each other with discharging opening 15; Described threshing tooth 9 is distributed on the described press strip 8, and vertical with its surface; Described firewood-plucking tooth 10 is " Z " type.

As depicted in figs. 1 and 2, start transmission mechanism 19, material is put into from charging aperture 22, import by the guide plate in the loam cake 16 17, then enter in the threshing chamber 2, cylinder 7 rotates along with the rotation of main shaft 1, thereby the threshing tooth 9 on the press strip 8 also rotates, make material in the process of rotation, be broken away from, inhaling the fan of penetrating in the chamber 4 11 is simultaneously also rotating, produce suction, faggot and thick foreign material are inhaled, through separation chamber 3, enter to inhale and penetrate chamber 4, in separation chamber 3, stir by the rotation of uprooting weed tooth 10, make long, thick faggot and a little bit smaller foreign material are separated, long, the grass outlet 6 that thick faggot is penetrated chamber 4 afterbodys along suction is gone out, simultaneously with the cereal of impurity during through screen cloth 12 scalpings, some weak point, tiny impurity, being sucked suction by fan 11 penetrates in the chamber 4, fly out along chaff discharging port 5, then fallen in the vibratory sieve that moves back and forth 13 that drives by eccentric stiffener 18 by cereal through scalping, under vibratory sieve 13 screening, according to the difference of proportion, gentle matter fine powder and tiny impurity are thereon, because its low weight suction by fan 11 is penetrated in the chamber 4, fly out along chaff discharging port 5, then the cereal that falls from vibratory sieve 13 drops on the recleaner screen 14, further cleans, cereal will be carried out four times and clean like this, last clean cereal is picked out by discharging opening 15, and cereal carries out four times in this machine separates, clean, thus clean, exempt to raise; Uprooting weed tooth 10 is separated for " Z " type is easy to make long, thick faggot and cereal and tiny impurity in said process, screen cloth 12, vibratory sieve 13, mesh on the recleaner screen 14 can be selected different sieve apertures for use according to the size of cereal, simultaneously clean screening step by step in order to be beneficial to, screen cloth 12, vibratory sieve 13, the mesh on the recleaner screen 14 reduces successively.
