Summary of the invention
The utility model provides a kind of swing type vibratory sieve cleaning plant to the problems referred to above, and this cleaning plant running is steady, and reliability is high.
Technical scheme according to the utility model: a kind of swing type vibratory sieve cleaning plant; Comprise sieve nest; The rear end of said sieve nest is fixed with two camshaft bearings; Rotatably mounted in said two camshaft bearings have a swinging axle, and the front end both sides of said sieve nest are hinged with fork respectively, and the other end of said fork is hinged on the body of grain header.
The bottom of said sieve nest is fixed with screen cloth, is fixed with deadlight longitudinally in the said sieve nest, is separately installed with the interlock sieve sheet of a plurality of adjustable knotter screen sheet aperture that is positioned at said screen cloth top about said deadlight and said sieve nest between two sidewalls.
The rear end of said sieve nest be provided be installed on respectively said deadlight and said sieve nest about straw shaker between two sidewalls.The two ends of each said sieve sheet are respectively arranged with sieve sheet folder, and an end of said sieve sheet folder is fixed on the said sieve nest, and its other end is fixed on the sieve sheet connecting plate.Said sieve sheet folder is processed by wear-resisting nonmetallic materials.Be hinged with a regulating block respectively on two sidewalls of said sieve nest; One end of said regulating block and said sieve sheet connecting plate are hinged; The other end of said regulating block is hinged with sieve sheet adjusting rod, and the other end of said sieve sheet adjusting rod is connected on the said sieve nest rear portion through threaded fastener.
The technique effect of the utility model is: the utility model changes sieve nest into crank and rocker mechanism by slider-crank mechanism, can reduce effectively to impact and friction, has improved smoothness of operation; About the sieve sheet is divided into two groups, increased the bearing capacity of sieve sheet, improved reliability; The sieve sheet clamping that process with the wear-resisting nonmetallic materials of damping at the two ends of sieve sheet is fixed, has reduced vibrations greatly, has improved wearability; Sieve sheet aperture governor motion adopts linkage, and is simple and reliable for structure, easy to adjust.And the adjustment of sieve sheet aperture governor motion is arranged on the rear portion of sieve nest, the adjustment of convenient sieve sheet aperture.

Embodiment
Be further described below in conjunction with the embodiment of accompanying drawing the utility model.
Among Fig. 1 ~ Fig. 6, comprise fork bearing pin 1, fork 2, sieve nest 3, camshaft bearing 4, swinging axle 5, sieve sheet folder 6, sieve sheet 7, sieve sheet adjusting rod 8, sieve sheet connecting plate 9, regulating block 10, straw shaker 11, deadlight 12, screen cloth 13 etc.
Like Fig. 1, Fig. 4 ~ shown in Figure 6; The utility model is a kind of swing type vibratory sieve cleaning plant, comprises sieve nest 3, and the rear end of sieve nest 3 is fixed with two camshaft bearings 4; Rotatably mounted in two camshaft bearings 4 have a swinging axle 5, and swinging axle 5 is rotated by drive mechanism; The front end both sides of sieve nest 3 are hinged with fork 2 respectively, and the other end of fork 2 is hinged on the body of grain header.This structure is to change former slider-crank mechanism into crank and rocker mechanism, and swinging axle 5 rotatablely moves, and then the fork 2 of front end is done the swing campaign, can reduce shock and vibration effectively, has improved smoothness of operation, noise in the time of can reducing the combine running.
Like Fig. 1～shown in Figure 3, the rear portion of sieve nest 3 is a straw shaker 11, and the middle part of sieve nest 3 is a double-layer structure up and down, and lower floor is the screen cloth 13 that is arranged on sieve nest 3 bottoms, and the upper strata is an interlock sieve sheet 7.
The utility model is fixed with deadlight 12 longitudinally in sieve nest 3, two spaces about sieve nest 3 is divided into, and interlock sieves sheet 7 and straw shaker 11 all is divided into left and right sides two halves, increases the bearing capacity of sieve sheet 7 and straw shaker 11, improves its reliability.Be separately installed with the interlock sieve sheet 7 that is positioned at a plurality of adjustable knotter screen sheet aperture above the screen cloth 13 between two sidewalls about deadlight 12 and sieve nest 3; The rear end of sieve nest 3 be provided be installed on respectively deadlight 12 and sieve nest 3 about straw shaker 11 between two sidewalls.
