Bar.
It is preferred that, the spacing of two rods is 1.2cm on the screen cloth, both can guarantee that sunflower seeds being moved through on screen cloth
Do not fallen out in journey, can guarantee that the impurity such as surface dust smoothly drop again.
The utility model, a kind of efficient melon seeds sieving machine：Crank disk drives link rotatable under buncher driving, even
The motion of the final drive driven member screen cloth of rotation of bar.Sunflower seeds material is moved on screen cloth, sunflower seeds and sunflower disk particle by
In coefficient of friction difference, movement velocity is different on screen cloth, completes separation during screen cloth downslide, part floral leaf and sprig,
The impurity such as surface dust carry out primary dcreening operation by screen cloth, and the jujube leaf not sieved thoroughly is cleaned by the way that negative pressure suction expansion chamber progress is secondary, sunflower seeds
Fall and be collected in collection melon case from vibratory sieve end, so as to realize the purpose that sunflower seeds is cleaned.
Under the driving of crankshaft connecting rod system, the motion of screen cloth promotes material to be moved along screen cloth, and material is moved on screen cloth
Predominantly following four state：
(1) relative static conditions：The speed of sunflower seeds material is identical with screen cloth translational speed, sunflower seeds material and screen cloth phase
It is 0 to speed, both are in geo-stationary.
(2) positive sliding mode：Material keeps contacting with working face, and material particles are more than work in the speed of screen cloth positive direction
Make the speed in face, i.e., the relative displacement for being more than zero screen cloth normal direction along the relative velocity of screen cloth positive direction is equal to relative velocity
Zero；
(3) reverse slide state：Material keeps contacting with working face, and material particles are less than work in the speed of screen cloth positive direction
Make the speed in face, i.e., the relative displacement for being less than zero screen cloth normal direction along the relative velocity of screen cloth positive direction is equal to relative velocity
Zero；
(4) sling movement state：Displacement of the sunflower seeds material perpendicular to screen cloth direction is more than 0, and sunflower seeds material is tossed,
Leave screen cloth.
A kind of efficient melon seeds sieving machine of the utility model, its advantage is：
1) the efficient melon seeds sieving machine can make wind be evenly distributed in whole screen cloth using the structure of adjustable wind deflector
On, and then increasing screen cloth air quantity, Optimum distribution is substantially improved and cleans effect；
