CN101091950A - New type roller picker - Google Patents

Abstract

The invention publics a new roller screen, which aims at the transmission part complex, breakdown and troubles in the existing roller screen. It is driven by the motor and reducer. The reduction gear and the sieves box installs on the identical chassis with incline arrange. The reduction gear is single input, double output, the middle driveshaft actuates by the electric motor through the belt pulley, the both sides from the moving axis through the shaft coupling connects with the sieve axis. The whole sieve is composed of muli-reductor units parallel. The dial-set of the sieve is the buckle type and easy to replace. According to the request, the battery solution throw out lever strobe is equipped with the feed inlet of the sieves box; when goes wrong, the material may pass from the bypass, not affect the overall system movement.

Description

A kind of novel roller picker

Technical field

The present invention relates to a kind of novel roller picker, belong to coal screening equipment.

Background technology

Roller picker is to be arranged in parallel by some, and the parallel axes that has dial rotates synchronously, promotes material and moves forward, and finishes the equipment of screening process simultaneously gradually.Current, the type of drive of roller picker roller bearing mainly contains chain wheel drive, bevel gear driving, and modes such as band decelerator motor-driven single shaft exist complex structure, fault rate height, safeguard problem such as inconvenience.Moreover be exactly that dial wearing and tearing back is changed and whole axle need be pulled down, workload is very big.

Summary of the invention

The present invention is directed to the problems referred to above, a kind of novel roller picker is provided, have simple in structure, reliable operation, characteristics easy to maintenance.

Technical scheme of the present invention is: a kind of novel roller picker, form by underframe, screen box, decelerator, sieve axle, dial, shaft coupling, bearing block, gate.It is characterized in that: dial is a button type, is connected on the sieve axle with counter-sunk screw.Decelerator and screen box are installed on the same underframe, are in tilted layout.Decelerator is single input, dual output, driving shaft in the middle of motor drives by belt pulley, and driven shaft connects with the sieve axle by shaft coupling.Bearing block places the screen box both sides.Whole screen(ing) machine can be formed in parallel by several decelerator unit.Screen box feeding mouth place is provided with the gate that Electrohydraulic push rod drives, and material can pass through from bypass when the sieve axle was not worked or broken down, and did not influence the operation of whole system.

The invention has the beneficial effects as follows: adopt the belt pulley transmission, play the function of overload protection; Adopt the type of drive of motor acceleration and deceleration device, reliability height, easy care; After the dial wearing and tearing, do not need whole sieve axle pulled down, it is convenient to change.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the schematic diagram of dial;

Fig. 4 is the A-A cutaway view of Fig. 3.

Among the figure: 1. underframe, 2. driven pulley, 3. decelerator, 4. screen box, 5. Electrohydraulic push rod gate, 6. bearing block, 7. make-up dial, 8. sieve axle, 9. shaft coupling, 10. hub, 11. dials, 12. screws.

The specific embodiment

As shown in Figure 1 and Figure 2, decelerator 3 is single input, dual output, the decelerator driving shaft is driven by driven pulley 2 by motor, and decelerator 3 both sides driven shafts drive sieve axle 8 constant speed by shaft coupling 9 and rotate in the same way, carry and saturating sieve thereby material is finished under the rotation of make-up dial 7.Decelerator 3 and bearing block are installed on the same underframe 1, with horizontal plane one angle α are arranged.Whole screen(ing) machine is made up of several above-mentioned decelerator unit as required.Bearing block 6 is installed in the both sides of screen box 4, and is convenient to check and maintenance.Screen box 4 feeding mouth places are provided with Electrohydraulic push rod gate 5, and material can not influence the operation of whole system from the logical reason of bypass when breaking down.

As shown in Figure 3, Figure 4,2 dials 11 are connected on the hub 10 by screw 12, and hub 10 is among the protection of dial 11, has only the side to be subjected to mild wear.

Claims (1)

1, a kind of novel roller picker is made up of underframe, decelerator, driven pulley, screen box, dial, sieve axle, bearing block, shaft coupling, electric liquid gate; It is characterized in that: dial is a button type, is connected on the sieve axle with counter-sunk screw; Decelerator and screen box are installed on the same underframe, are in tilted layout; Decelerator is single input, dual output, driving shaft in the middle of motor drives by belt pulley, and driven shaft connects with the sieve axle by shaft coupling; Bearing block places the screen box both sides; Whole screen(ing) machine can be formed in parallel by several decelerator unit; Screen box feeding mouth place is provided with the gate that Electrohydraulic push rod drives.
