Abstract
The utility model relates to a beam swinging screener, relating to the separating class of solids. The utility model is structurally characterized in that an eccentric wheel (8) is hinged with a big connecting rod (7), and the other end of the big connecting rod (7) is hinged with one end of each of big swinging beams (5). The big swinging beams (5) are fixed to a machine body by a bearing (6), and big swinging beams (5) of both ends of the bearing (6) are respectively hinged with a small connecting rod (4). The other end of each small connecting rod (4) is hinged with a small swinging beam (2) which is fixed to the machine body by the bearing (3), and both ends of each swinging beam (2) are respectively hinged with a screen box (1). The eccentric wheel (8) of the utility model can push the big connecting rod 7 to move, and in the end, the screen box (1) can be pushed to make reciprocating movement frontward and backward by multi-stage transmission. As a consequence, the utility model can achieve the purpose of screening grains.
Description
The utility model belongs to solid and separates class with solid, specifically a kind of rocker-arm classifying screen.
As everyone knows, the grain processing classifying screen, each layer screen box all is equipped with a cover transmission system, comprise a power transmission shaft, two eccentric wheels, two sprocket wheels, a chain, two connecting rods, a plurality of bearing and bearing blocks compositions, the classifying screen of this structure, cost is higher, and the friction collision takes place in guide bearing and screen frame (unit) during running, sieve nest shake is bigger, and consumable accessory is more, influenced service life.
The utility model purpose is, provides that a kind of cost is low, jitter amplitude is little, the rocker-arm classifying screen of long service life.
Of the present utility model being characterised in that: be hinged with the big connecting rod big connecting rod other end on the eccentric wheel and be hinged with big rocking arm one end, big rocking arm through bearing fixing on body, be hinged with a small rod on the big rocking arm at bearing two ends respectively, the small rod other end and small rocker are hinged, on body, the small rocker two ends are hinged with a screen box respectively to small rocker through bearing fixing.
The utility model can reduce product cost significantly, screen box collisionless phenomenon, and sieve nest does not produce shake, in addition owing to adopt bearing to be hinged, can prolong sieve nest service life.
The utility model is described in detail by embodiment below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
The utility model eccentric wheel 8 is fixed on the support, by Motor Drive, big connecting rod 7 one ends are hinged by bearing and eccentric wheel 8, the other end is hinged with big Rocker arm 5 one end, big Rocker arm 5 is fixed on the body through bearing 6 and bearing block, and the other end of 4, two small rods 4 of hinged two small rods of symmetry is hinged with a small rocker 2 respectively on the big Rocker arm 5 of bearing 6 both sides, each small rocker 2 middle part is fixed on the body through bearing 3, and small rocker 2 two ends are hinged with a screen box 1 respectively.
During the work of the utility model rocker-arm classifying screen, Motor Drive eccentric wheel 8 rotates, eccentric wheel 8 drives big connecting rod 7 and makes front-rear reciprocation movement, big Rocker arm 5 is promoted by big connecting rod 7 again and swings around bearing 6, big Rocker arm 5 drives two small rod 4 front-rear reciprocation movements, two small rockers 2 are around bearing 3 swings successively, thus totally four of screen box 1(that two small rockers 2 promote respectively to be hinged separately) live reciprocating cutter before and after synchronously, finish the screening of grain is operated.
Claims (1)
