Description
Technical field
The utility model belongs to paddy rice, wheat threshing field, the semi-feeding thresher of particularly a kind of paddy rice, wheat.
Background technology
Existing rice-wheat thresher is mainly by the threshing assembly, and cover assembly provides the electromotor and the transmission mechanism of power for the cylinder in the threshing assembly; Separating net-screen and dressing mechanism are formed, and not enough below existing: (1) dressing mechanism adopts horizontal blower fan usually, and the impeller of said horizontal blower fan is made up of three blades; Its length is basic identical with thresher length; Impeller is not easy balancing, causes that vibrations are big, noise is big, and blower fan is out of order easily.(2) thick slag floss hole is not set, thick slag can only piled up more for a long time, and the window of pushing the cover assembly back open discharges, and shuts after having arranged again, and when the thick slag of row, can a part of seed also be discharged, and causes the threshing loss.(3) owing to only be provided with the mesh screen that steel wire is made on the cover assembly, and this mesh screen installs perpendicular to horizontal plane, thereby seed splashes seriously during threshing, and exhaust is not smooth, and dust is big.
Summary of the invention
The utility model provides a kind of semi-feeding rice and wheat thresher to the existing deficiency that exists, and to reduce grain loss, the noise when reducing work improves service life.
The said semi-feeding rice and wheat thresher of the utility model; Comprise upper spider, lower bearing bracket is installed in separating mechanism and cover assembly on the upper spider; The electromotor and the transmission mechanism of power are provided for the cylinder in the separating mechanism; Be installed on the lower bearing bracket and be arranged in the separating net-screen under the cylinder of separating mechanism, be installed in the dressing mechanism on the lower bearing bracket, be installed in the discharge bucket that the skull seed is sent into dressing mechanism that contains that is used on the lower bearing bracket after the separating net-screen rough segmentation; Said dressing mechanism is the axial fan structure, comprises air duct and impeller, and the last cambered surface of air duct offers charging aperture; Side at charging aperture is provided with deep bead; The lower camber side of air duct offers the seed outlet, and an end of air duct is provided with impeller, and the other end of air duct is rice slag or wheat husk outlet.
For the ease of the smoothing weighing apparatus; Reduce noise and vibrations, the said semi-feeding rice and wheat thresher of the utility model, its transmission mechanism is a belt gear; Drive pulley in impeller in the said dressing mechanism and the said belt gear is combined into one, by a motor drives.
In order to prevent the seed discharge, the rice slag or the wheat husk exit of the air duct in the said semi-feeding rice and wheat thresher of the utility model dressing mechanism are equipped with adjustable plate, can be according to its position of wind-force size adjustment.
The said semi-feeding rice and wheat thresher of the utility model; Its separating mechanism comprises drum assembly, be arranged on bow tooth on the cylinder in the drum assembly, be arranged on the upper spider with the fixed teeth of bow tooth assembly and be arranged on the workbench on the upper spider; The bottom of said workbench is provided with thick slag outlet; But threshing limit, limit deslagging is unlikely to cause thick slag muck long-pending.
The said semi-feeding rice and wheat thresher of the utility model; Its cover assembly is closed by left plate, right plate, cover plate and the first nylon mesh screen and the second nylon wire screen banks that are positioned at the rear portion and forms; The first nylon mesh screen is positioned on the second nylon mesh screen; And the angle of the first nylon mesh screen and horizontal direction is 40 °～50 °, the nylon mesh screen be arranged on threshing the time can avoid seed to splash, exhaust is not smooth.
The threshing course of the said semi-feeding rice and wheat thresher of the utility model: make threshing assembly and dressing mechanism simultaneously in running order behind the motor start-up; The operator is with wheat bundle or rice bundle feeding threshing chamber (space that is surrounded by workbench and cylinder); And constantly stir wheat bundle or rice bundle; Seed is taken off under the effect of bow roller gear; Disconnected fringe on wheat bundle or the rice bundle etc. is cut off under the effect of bow roller gear and fixed teeth and forms thick slag; Thick slag, seed, wheat husk, thin slag etc. are brought into the separation chamber (space that is surrounded by separating net-screen and cylinder) of thresher bottom under the rotation wind-force of cylinder, separating net-screen separates thick slag with seed, wheat husk and thin slag, and thick slag is brought into the workbench bottom through thick slag outlet discharge with the cylinder rotation; Seed, wheat husk, thin slag get into the air duct of dressing mechanism through discharge bucket; Under the wind that impeller produced, wheat husk, thin slag etc. to be discharged from the deslagging port of air duct, the seed after selection by winnowing then offers the seed outlet from the air duct lower camber side and discharges.
The utlity model has following beneficial effect:
1, because dressing mechanism is the axial fan structure, and a side of its charging aperture is provided with deep bead, thereby one be that the wind of blower fan does not up blow, and threshing chamber is no longer included pass through wind, the 2nd, improved the selection by winnowing effect.
2, the drive pulley of the impeller of blower fan and transmission mechanism is combined into one, and not only is convenient to the smoothing weighing apparatus, reduces fan noise and vibrations, and makes compact conformation, and installation procedure reduces.
3, at the rice slag or the wheat husk exit install adjustment plate of air duct, can avoid seed to be discharged from according to its position of wind-force size adjustment.
4, thick slag outlet is set in the bottom of workbench, can realizes threshing limit, limit deslagging, efficiently solve the accumulation problem of thick slag at threshing chamber.
5, the first nylon mesh screen and the second nylon mesh screen are installed at the rear portion of cover assembly; And the angle of the first nylon mesh screen and horizontal direction is 40 °～50 °; Thereby seed splashes on the mesh screen and do not splash, and the dust that threshing produces can very unimpededly be discharged by the nylon mesh screen.
