Abstract
An adjustable link transmission device of a movable sieve jig belongs to the technical field of coal washing equipment and solves the problems of low probability of adjustment to amplitude of the movable sieve and poor separating effect in the prior mechanical movable sieve jig. The utility model adopts the technical scheme as follows: the adjustable link transmission device comprises a power connecting rod, a movable sieve connecting rod and bolts, a power transmission component of a motor is connected with the power connecting rod, the movable sieve connecting rod is connected with a movable sieve body, the power connecting rod is connected with a movable sieve connecting rod through the bolt, a plurality of bolts are arranged on the connecting surfaces in rows at intervals, and the power connecting rod is in one-to-one correspondence with a bolt hole on the movable sieve connecting rod. The utility model can adjust the positions of connecting bolts of two connecting rods and lengths of the connecting rods, thereby adjusting the movement amplitude of the movable sieve body and improving the separation effect. The utility model has the advantages of simple structure, convenient operation and low operating failure rate.
Description
Technical field
The utility model relates to a kind of actuating unit of mechanical type movable-sieve jig, belongs to the wash coaling equipment technical field
Background technology
Movable-sieve jig is that a kind of direct outer power driving sieve nest moves up and down in aqueous medium, causes material periodically loose, realizes the screening installation by density stratification, is widely used in the ideal equipment of piece raw coal discharge refuse and steam coal separation.Movable-sieve jig divides fluid pressure type to drive and mechanical type drives two kinds, the driving force of hydraulic pressure movable-sieve jig is provided by hydraulic system, good separation effect, and the hydraulic system adjusting range is wide, easy to operate, but hydraulic-driven part cost height, frequent speed change transformation work are to the requirement harshness of Hydraulic Elements, and diagnosis when breaking down and eliminating be difficulty relatively, the maintenance cost height, also high to the technical level of operators requirement, cause the hydraulic pressure movable-sieve jig to be not easy to popularize, range of application is narrow.The present mechanical type movable-sieve jig that uses, driving force is provided by mechanical component, and it is simple, reliable to have an attended operation, and cost is low, and advantage easy to maintenance receives praises from customers, but separating effect is not ideal enough.Trace it to its cause, find that existing machinery formula movable-sieve jig adopts simple toggle to drive the sieve nest motion, the characteristics of motion that this type of drive produced is undesirable, and quickreturn characteristics is not obvious, thereby causes the separating effect of lump coal good not as the fluid pressure type jigging machine.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of by regulating length of connecting rod, reach and regulate the size of moving the sieve amplitude, solve the adjustable link gearing that the existing motor-driven sieve amplitude of old-fashioned mechanical type vibro-assisted jigging is difficult for the movable-sieve jig of adjusting, separating effect difference.
The technical scheme that solves the problems of the technologies described above is:
A kind of adjustable link gearing of movable-sieve jig, it is connected by power, and connecting rod, moving sieve connect connecting rod, bolt is formed, the power driving module of motor is connected connecting rod with power a end is connected, the end that moving sieve connects connecting rod connects moving sieve sieve nest, and the other end that power connects connecting rod is connected with the other end that moving sieve is connected connecting rod.
The adjustable link gearing of above-mentioned movable-sieve jig, described power connect the double link structure that connecting rod is a symmetry, and double link lays respectively at the both sides that moving sieve connects connecting rod, are connected the connecting rod clamping engagement with moving sieve.
The adjustable link gearing of above-mentioned movable-sieve jig, described power connection connecting rod is connected connecting rod with moving sieve be that bolt connects, a plurality of bolts are arranged on joint face, and they are arranged in equally spaced many rows, and it is corresponding one by one with the bolt hole position that moving sieve connects on the connecting rod joint face that power connects connecting rod.
The utility model can change two length that connect connecting rod by adjusting two connecting bolts that connect connecting rod, adjusts the amplitude of sieve nest motion with this, improves separating effect.Advantage simple in structure, easy to operate, that the operation troubles rate is extremely low that the utility model also has is compared with the moving screen device of the hydraulic pressure of same treatment ability and also to be had tangible price advantage, is specially adapted to technologies such as jigging discharge refuse, has broad application prospects.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Mark is as follows among the figure: power connects connecting rod 1, moving sieve connects connecting rod 2, bolt 3, moving sieve sieve nest 4
The specific embodiment
As seen from the figure, the utility model is made up of power connection connecting rod 1, moving sieve connection connecting rod 2, bolt 3.The power of motor is delivered to power through transmission component and connects connecting rod 1.Power connects connecting rod 1 and is connected connecting rod 2 with moving sieve by bolt 3 connections.Moving sieve connects the moving sieve of connecting rod 2 connections sieve nest 4 and the moving sieve of final lifting sieve nest 4 is done reciprocal jigging motion.
Show among the figure that it is the symmetric double bar linkage structure that described power connects connecting rod 1, two bar linkage structures are identical, are clipped in the both sides that moving sieve connects connecting rod 2 respectively.Connect power connection connecting rod and on joint face, be arranged in equally spaced a few row with the bolt that moving sieve is connected connecting rod, operating personnel can select the link position up and down of bolt as required, connect connecting rod and the moving mutual alignment that connects between the connecting rod of sieving to regulate power, the various amplitude of the different corresponding moving sieve sieve nests in mutual alignment reaches the moving best amplitude that sieves sieve nest by adjustment between them.
The utility model is used for mechanical movable-sieve jig, and its course of work is as follows: when movable-sieve jig was worked, moving sieve sieve nest was done upper and lower reciprocal jigging motion by adjustable link gearing drive under the effect of actuating unit.After feed coal feeds, on sieve nest, form bed.Adjustable link gearing hauls from sieve nest and moves upward, and material is held up by whole layer; Sieve nest descends fast when reaching amplitude height point, and the particle of different densities is with the sedimentation in water of different speed.Regulate adjustable link gearing and adjust the best amplitude of moving sieve.Finally through moving up and down for several times repeatedly, material is realized by density stratification, and is moved forward with the sieve nest that tilts.The light material in upper strata and lower floor's spoil are discharged respectively.Reach the purpose of discharge refuse sorting.
