Specific embodiment
The invention embodiment is described in detail below in conjunction with the accompanying drawings.A kind of gravity flow screen is combined with movement rake teeth
Formula grain cleaning mechanism, along the fixed installation sorting screen 5 being longitudinally arranged inclined on the intermediate position of support assembly 1,
The more bar shaped boss 16 of installation successively being mutually parallel along longitudinal direction on 5 upper surface of sorting screen；In 1 upside of support assembly
In portion, at position above sorting screen 5 can longitudinally reciprocal movement installation harrow frame 6, on 6 following side of harrow frame transversely
Multiple toothholders 4 are installed successively, rake teeth 3 can the hinge of longitudinal oscillation be mounted on 4 following side of toothholder, rake teeth connecting rod 13 is inserted successively
Enter to be packed on rake teeth 3, multiple rake teeths 3 are solidly fixed, Π types hock 17 is mounted on 3 bottom end of rake teeth, Π type hocks
In 17 groove between adjacent bar boss 16；Driving is rotatably equipped in the rear lateral portion of the support assembly 1
Axis 11, eccentric wheel A 10 and eccentric wheel B 15 are packed in successively in drive shaft 11, and rotatably set is matched for the rear end of harrow frame drive rod 7
In eccentric wheel B 15, front end and the harrow frame 6 of harrow frame drive rod 7 are hinged, and the rear end of rake teeth drive rod 9 rotatably covers
In eccentric wheel A 10, sliding block 8 can longitudinally reciprocal movement be mounted on 1 upper back of support assembly on, rake teeth drive rod 9
Front end is hinged with sliding block 8, and the front and back ends of bracing wire 14 are connect respectively with rake teeth 3 and sliding block 8；Flexible tensile spring 18 it is upper,
Lower both ends are connected on toothholder 4 and rake teeth 3.It is set in 1 upper front end of support assembly, at position above sorting screen 5
Merging material slide plate 2, in 1 rear end lower of support assembly, sets impurities removal slide plate 12 at 5 lower portion of sorting screen.
During operation, cereal is fallen under pan feeding slide plate 2 on fixed 5 forward upper of sorting screen, and outer defeated power passes through
Drive shaft 11 drives eccentric wheel A 10 and eccentric wheel B 15 to rotate, and wherein the rotary motion of eccentric wheel B 15 is successively through harrow frame drive rod
7th, harrow frame 6, toothholder 4 are whole drives rake teeth 3 to complete straight reciprocating motion relative to sorting screen 5 along longitudinal direction, and rake teeth 3 will be located at bar shaped
Empty miscellaneous remaining from front to back by being discharged at impurities removal slide plate 12, the groove between adjacent bar boss 16 of 16 upper support frame of boss
Cereal and small miscellaneous remaining taken off successively to rear side from the front side of sorting screen 5 are harrowed movement by interior Π types hock 17, make cereal successively from clear
Choosing 5 sieve pores of sieve fall, and separation is cleaned in completion, it is small it is miscellaneous more than discharged from impurities removal slide plate 12.In operation process, when harrow frame 6 is from cleaning
When 5 rear side of sieve is to front side drawback movement, the rotary motion of eccentric wheel A 10 by rake teeth drive rod 9, bracing wire 14 pull rake teeth 3 around
It is rotated with the hinge point of toothholder 4 to rear side, Π types hock 17 is driven to be detached from the cooperation with sorting screen 5, at this time flexible tensile spring
18 stress extension elongations, when harrow frame 6 is revert at 5 front side position of sorting screen, sliding block 8 moves forward, while bracing wire 14 is loosened,
Under 18 return pulling force effect of flexible tensile spring, rake teeth 3 drives Π types hock 17 to be returned to and 5 matched operation position of sorting screen
It puts, cereal is carried out taking off the mobile operation of rake again, be recycled successively.
