Abstract
The utility model relates to a grain thresher which mainly solves the problem of the existing grain thresher that belts are easy to wind up by straws. A sieve driving wheel is connected with a driven wheel through a belt, a draw rod is arranged at the eccentric position of the driven wheel, so that the draw rod can move along top-and-bottom direction following the rotation of the driven wheel. The draw rod is connected with a sieve through a drive mechanism.
Description
The utility model relates to threshing machine.
Present existing threshing machine, sieve driven pulley be positioned at the sieve driving wheel below, the sieve driven pulley drives the motion that pull bar is done left and right directions, thereby makes the sieve that links to each other with pull bar do the motion of left and right directions.The threshing machine of this structure and since the sieve driven pulley be positioned at the sieve driving wheel below, straw on the ground snarls the belt on the wheel easily, has driving belt need be twisted into 90 ° again, so the inconvenience of using.
The purpose of this utility model is to provide a kind of threshing machine easy to use.
The technical solution of the utility model: the sieve driving wheel connects a driven pulley through belt, and the driven pulley eccentric position is connected to a pull bar, makes pull bar can do the motion of above-below direction with the rotation of driven pulley, and pull bar connects sieve through transmission mechanism.
Advantage of the present utility model, driven pulley has certain distance apart from ground, and straw is difficult for snarling belt, and the belt between driving wheel and the driven pulley need not be twisted into 90 °, makes belt prolong service life.
Narrate embodiment of the present utility model in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
During enforcement, transmission mechanism is to constitute like this, and pull bar 3 connects a Rocker arm 4, and rocking arm connects rocker arm shaft 5, and rocker arm shaft connects sieve 7 through rocking arm 6.During work, power input wheel 8 is rotated by motor drives, and sieve driving wheel 1 rotates thereupon, driven pulley 2 also rotates through belt transmission thereupon, thereby make pull bar 3 do the motion of above-below direction, Rocker arm 4 is done the motion of above-below direction thereupon, and rocker arm shaft 5 drives two rocking arms 6 makes sieve 7 do double swerve.
Claims (2)
1, a kind of threshing machine that constitutes by sieve driving wheel etc., it is characterized in that: the sieve driving wheel connects a driven pulley through belt, the driven pulley eccentric position is connected to a pull bar, makes pull bar can do the motion of above-below direction with the rotation of driven pulley, and pull bar connects sieve through transmission mechanism.
2, threshing machine according to claim 1 is characterized in that: transmission mechanism is to constitute like this, and pull bar connects a rocking arm, and rocking arm connects rocker arm shaft, and rocker arm shaft connects sieve through rocking arm.
