Abstract

The utility model relates to a sorting screen, belonging to the mechanical technical field of grain processing that objects can be separated according to different granularity. The utility model mainly adopts an eccentric wheel 8 to drive a drive shaft 11 to rotate, and connecting shafts 10, 17 can be driven to make reciprocating movement frontward and backward by a connecting rod 12 connected with the drive shaft 11 and the connecting shafts 10, 17. Thus, the utility model can realize frontward and backward reciprocating movement of screen nets 1, 2. The utility model has simple and reasonable structure, harmonious and stable operation and increased service life of each part and each component.

Description

Sorting screen

A kind of classifying screen belongs to article by different grain size its Cereals Processing Machines technical field of separating.

In the background technology, classifying screen is varied, and a kind of is to utilize sprocket wheel, chain to drive a plurality of driving shafts, the driving shaft two ends are equipped with the eccentric wheel that links to each other with screen cloth, utilize eccentric wheel, and it is forward and backward mobile to drive screen cloth, with varigrained article separately, this classifying screen, the one, transmission chain length, power consumption is big, the 2nd, driving shaft two ends eccentric wheel is in running, and is asynchronous, and the screen cloth operation is not steady, axle and sprocket wheel are produced impulsive force, cause axle, sprocket wheel rapid wear; Another kind of classifying screen utilizes a line shaft, drives two eccentric wheels, and these two eccentric wheels drive two classifying screen motions separately, because the existence of making, alignment error in running, forms impulsive force to line shaft, the axle rapid wear.

The purpose of this utility model is to provide a kind of rational in infrastructure, each a kind of classifying screen of parts long service life in addition for society.

The utility model is achieved by the following technical solution: the utility model mainly is made up of frame, power unit, gear unit and screen cloth, gear unit is made of the eccentric wheel that links to each other with power unit, driving fork, driving shaft, fixedly be equipped with the connecting rod that links to each other with connecting axle on the driving shaft, power unit drives eccentric wheel and rotates, eccentric wheel drives drive shaft turns by driving fork, connecting rod is fixedlyed connected with driving shaft and connecting axle, drive shaft turns, cause connecting axle forward and backward mobile, screen cloth moves back and forth before and after realizing.

Below, reach embodiment in conjunction with the accompanying drawings, the utility model is described in detail in detail.

Fig. 1, the utility model general structure schematic diagram,

Fig. 2, the utility model screen cloth one end suspension arrangement schematic diagram.

Drawing explanation: 1, screen cloth; 2, screen cloth; 3, frame; 4, motor; 5, belt pulley; 6, belt pulley; 7, driving wheel; 8, eccentric wheel; 9, drive fork; 10, connecting axle; 11, driving shaft; 12, connecting rod; 13, hang the support bolt; 14, hanger bar; 15, hang the support bolt; 16, connector; 17, connecting axle.

This example mainly is made up of frame 3, power unit, gear unit, screen cloth 1,2.Power unit is mainly by motor 4, belt pulley 5,6 and driving wheel 7 constitute, gear unit is by the eccentric wheel 8 that links to each other with driving wheel 7, drive fork 9 and driving shaft 11 formations, fixedly be equipped with on the driving shaft 11 and connecting axle 10,17 connecting rods 12 that link to each other, during operation, driving wheel 7 drives eccentric wheel 8 and rotates, drive driving shaft 11 rotations by driving fork 9, driving shaft 11 rotates, drive connecting axle 10 by connecting rod 12, before 17, the back moves back and forth, screen cloth 1,2 respectively by connector 16 and connecting axle 17,10 is fixedly connected, screen cloth 1, before 2 realizations, the back moves back and forth, screen cloth 1,2 the other end utilizes to hang and supports bolt 13,15 link to each other with frame 3 with hanger bar 14.

The utility model utilizes an eccentric wheel 8 to drive a driving shaft 11 and rotates, and utilizes the connecting rod 12 of fixedlying connected with driving shaft 11 to drive screen clothes 1,2 forward and backward reciprocating motions again, and is simple and reasonable, operation harmony, steadily, each in addition, parts increase in service life.
