Abstract

The utility model discloses a separating screen machine comprising a frame. The top of the frame is provided with a feed hopper. The bottom of the feed hopper is provided with a discharge hole. A stirring discharge shaft is rotatably connected inside the feed hopper. A stirring discharge motor driving the stirring discharge shaft is mounted on the frame. A stirring arm axially arranged on the stirring discharge shaft is mounted on the stirring discharge shaft. The upper portion of the frame is provided with a transverse suspension shaft. Suspension arms extending down are hinged to two ends of the suspension shaft. At least one oblique screen frame layer is disposed below the hopper. The bottom of each screen frame is provided with a screen. Support shafts rotatably connected to the suspension arms are mounted on the screen frames. The frame is further provided with a rocking drive device which drives the suspension arms to rock back and forth. The bottom of the frame is further provided with a receiving hopper below the screens. The separating screen machine has the advantages of convenience in manufacture, mounting and operating, high screening efficiency and high unloading efficiency.

Description

A kind of material separating sieve

Technical field

The utility model relates to a kind of material separating sieve.

Background technology

At present, the structure of existing screening machine comprises frame, is elasticly connected with screening frame in frame, on screening frame, vibrating motor is housed, and makes to sieve frame and produces shake, thereby realize the screening of material by the vibrations of vibrating motor.The screening machine of this structure is because the vibration frequency of vibrating motor is too frequent, while sieving for the larger material of grain graininess difference, there is the shortcoming that screening efficiency is low, and inhomogeneous when discharging bin is thrown in material to screening in frame, thereby cause the shortcoming that screening efficiency is low.

Utility model content

The technical problems to be solved in the utility model is to provide the material separating sieve that a kind of screening efficiency is high, discharge rate is fast.

For solving the problems of the technologies described above, the material separating sieve providing comprises frame, hopper is equipped with at the top of frame, the bottom of hopper is provided with discharging opening, its design feature is to be rotatably connected to and to stir discharging axle in hopper, in frame, be equipped with to drive and stir the stirring discharging motor that discharging axle rotates, stir on discharging axle and be equipped with along its axial mixing arm arranging, upper rack is equipped with the suspended axle of horizontally set, the both ends of suspended axle are hinged with down the suspension arm of stretching, the below of hopper is provided with the screen frame that at least one deck is obliquely installed, the bottom of screen frame is provided with screen cloth, the back shaft being rotatably connected on suspension arm is housed on screen frame, the oscillatory gearing mechanism that drives suspension arm swing is also housed in frame, the receiving hopper that is positioned at screen cloth below is also equipped with in the bottom of frame.

Described oscillatory gearing mechanism comprises the crank that is rotatably connected in frame and is connected in frame and engine that driving crank rotates, between crank and suspension arm, connecting rod is housed.

Two-layer screen frame is set altogether, and two screen frames are from going to rear-inclined to arrange downwards, and described receiving hopper is tilted to lower setting from its horizontal opposite side of a horizontal side direction of frame.

Adopt after said structure, material can evenly be discharged from discharging opening after entering hopper under the rotation agitaion of stirring discharging axle, greatly reduce the sieving time of material, by power set, order about drive shaft turns, by oscillatory gearing mechanism, drive the front portion of screening frame to teetertotter, when screening frame teetertotters, the large granular materials after screening can be unloaded it fast by the uphill process at its rear portion, large granular materials flows out from discharging supporting plate, and small particles material leaks down from screening frame bottom.In sum, the utility model manufacture, installation, easy to operate, have advantages of that screening efficiency is high and discharging efficiency is high.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural representation of a kind of most preferred embodiment of the utility model;

Fig. 2 is the structural representation of the left apparent direction of Fig. 1.

The specific embodiment

Material separating sieve as depicted in figs. 1 and 2, it comprises frame 1, hopper 2 is equipped with at the top of frame 1, the bottom of hopper 2 is provided with discharging opening, in hopper 2, be rotatably connected to and stir discharging axle 12, in frame, be equipped with to drive and stir the stirring discharging motor 13 that discharging axle 12 rotates, stir on discharging axle 12 and be equipped with along its axial multiple mixing arms 14 that arrange, the length of multiple mixing arms 14 is consistent, the suspended axle 3 of horizontally set is equipped with on frame 1 top, the both lateral sides symmetry that is frame 1 is equipped with holder, above-mentioned suspended axle 3 is connected between two holders, the both ends of suspended axle 3 are hinged with down the suspension arm 4 of stretching, the top that is suspension arm 4 is hinged on suspended axle by sleeve, and on suspended axle, be bolted with the bolt of sleeve axial location, thereby guarantee that suspension arm 4 can only rotate and can not produce and move axially around suspended axle 3, and two spaced suspended axles 3 are set before and after in the present embodiment altogether, the both ends of two suspended axles 3 are hinged with respectively suspension arm 4, thereby the swing that makes screen frame 5 is more stable and have rhythm, be convenient to improve screening effect, the below of hopper 2 is provided with the screen frame 5 that at least one deck is obliquely installed, the bottom of screen frame 5 is provided with screen cloth, the back shaft 7 being rotatably connected on suspension arm 4 is housed on screen frame 5, the oscillatory gearing mechanism that drives suspension arm 4 swings is also housed in frame 1, in the present embodiment, two-layer screen frame 5 is set altogether, two screen frames 5 are from going to rear-inclined to arrange downwards, because screen frame 5 is obliquely installed, thereby when oscillatory gearing mechanism orders about its swing, in screening, made the action of discharging, the receiving hopper 8 that is positioned at screen cloth below is also equipped with in the bottom of frame 1, described receiving hopper 8 is tilted to lower setting from its horizontal opposite side of a horizontal side direction of frame 1, can make a horizontal side of the flow direction of material frame falling from screen bottom, thereby avoid the rerolling after material screening.

As shown in Figure 1, oscillatory gearing mechanism comprises the crank 9 being rotatably connected in frame 1 and the engine 10 that is connected in frame 1 and driving crank rotates, between crank 9 and suspension arm 4, connecting rod 11 is housed, adopt the drives structure form of above-mentioned crank connecting link, make drives structure not only simple and more reliable and more stable.

The above is specific constructive form of the present utility model; the utility model is not restricted to the described embodiments; the art personnel, the equivalent variations based on concrete structure on the utility model and parts are replaced all in protection domain of the present utility model.
