Abstract

The utility model discloses a granule climbing type grading screening apparatus. The back end of the screening sheet of the screening ship of the utility model is higher than the front end, and both sides of the waist part of a ship body is obliquely provided with a vibrating motor corresponding to the ship body. Under the action of the vibrating motor and an elastic supporting system, the screen ship carries out the resonance in the horizontal direction and in the vertical direction, the screened material is screened on the screening sheet in the jumping and climbing way. The utility model which has the advantages of reasonable design and compact structure is suitable for the grading screening of the material with different granularity, the abuse of grade jumping of the existing equipment is overcome, the screening accuracy rate and the production efficiency are high, and the multiple efficient specifications of one-time screening can be obtained.

Description

Granules up-stepped screening apparatus

The utility model belongs to sieving and grading equipment and technology scope, relates to the sieving and grading equipment of granule materials such as a kind of shelled peanut.

Many granule materials are arranged, as shelled peanut etc., the granular size inequality, the particle diameter difference is bigger, needs classification as requested.At present, the sieving and grading equipment of shelled peanut mainly is the rolling gliding style screening machine down that shakes, and the rear end of sieve ship sieve sheet is lower than front end, by mechanical driving devices such as connecting rod or cams, motion is reached sieve nest, make by the sieve material and overcome self-flowing angle and roll to downslide by the sieve nest rolling of shaking, and realize sieving and grading along compass screen surface.The subject matter that such sieving and grading equipment exists is: to roll across in the journey flowed fluctuation big sliding for material, skip a grade easily, even directly do not slide and be rolled into discharging opening through screening, therefore, the accuracy rate of sieving and grading and the stability of production process all can not be satisfactory, and the specification that once can effectively sieve is also less; Defectives such as also there is the transmission complexity in this in addition screening plant, efficient is low, noise is big, easy break-down are in the requirement that all can not adapt to peanut outlet and production and processing on the technical performance or on screening efficiency far away.

Task of the present utility model is by improving the screen of existing sieving and grading equipment, provide a kind of sieve accuracy rate height, production stability good, once sieve many shaking of specification and climb formula sieving and grading equipment, to overcome the existing above-mentioned shortcoming of prior art equipment.

The utility model improves realization on the prior art basis, it comprises the sieve ship, its main points are that the rear end of sieve ship sieve sheet is higher than front end, hull waist both sides are sieved the oblique installation vibrating motor of ship relatively, make the sieve ship under the vibration and elastic supporting system effect of vibrating motor, level and resonance up and down before and after producing sieve classification thereby make by the beating climbing of sieve material on the sieve sheet.

Fig. 1 is the three-dimensional structure diagram of the utility model sieve ship.

Below in conjunction with accompanying drawing the utility model is elaborated:

By shown in Figure 1, (15) are hulls among the figure, and are box for the strip upper shed, stretch part behind distribution box (2) hull (15), and (1) is discharging opening; The front end of hull (15) is a feeding mechanism, wherein (20) are hopper, (19) be the feeding vibrator, (21) be vibration refining tongue, vibration refining tongue is positioned at hopper (20) lower part outlet place, and link to each other with vibrator (19), feeding mechanism is fixedly supported upon on the base frame (16) by hopper supporting plate (18) and support (17); The following of hull (15) is elastic supporting system, and is installed on the base frame (16) by this supporting system; Install several layers sieve sheet (22) in the hull (15) from bottom to top, be fixed by sieve pressing plate on chip (23), its main points are that the rear end of sieve ship sieve sheet (22) is higher than front end, are advisable to be not more than 25 ° in the elevation angle; The oblique installation vibrating motor of the relative hull in waist both sides (12) of hull (15), under the vibration and elastic supporting system effect of vibrating motor (12), make sieve ship back level and resonance up and down before death, thereby make the climbing of on each layer sieve sheet, beating of screened material sieve classification.

For adapting to the requirement of material of different grain size sieving and grading, make the level and the up-down vibration component of sieve ship front and back adjustable, the sieve sheet elevation angle is adjustable by the sieve ship, said vibrating motor (12), its one can be equiped with the angular adjustment dish (11) of a band arc bolt guide groove (10), above-mentioned said hull (15) the waist both sides that are installed in are to install with tight fixed bolt by this angular adjustment dish (11).Loosening tight fixed bolt (9) by angular adjustment dish (11) whirling vibration motor (12), sieves ship front and back level and up and down oscillating component thereby regulate along bolt guide groove (10), reaches the requirement that adapts to the material of different grain size screening.

Said supporting system can and be fixed on base plate (3), (4) on the base frame (16) by the top board (5) of bolster (6), axle sleeve (8), fixed hub, and two ends are separately fixed at elastic support on top board and the base plate (7) and constitute up and down.The base plate of sieve ship rear end supporting system can be a pair of clapboard (3), (4), and being used for the bolt hole that same base frame (16) installs and fixes on the following wedge (3) is vertical strip hole.Loose bolts vertically moves wedge (3), thereby sieve ship rear end is raise or decline, realizes the adjusting at sieve sheet (22) elevation angle, also can reach the requirement that adapts to the material of different grain size screening.

For adapting to the requirement of sieve ship resonance better, improve the resonance performance of sieve ship, the elastic support of said supporting system (7) can adopt spring-rubber structure, makes with glue-pouring method.

For making the front-end and back-end vibration balancing of sieve ship harmonious, be convenient to balance adjustment, said hull (15), its two ends, bottom side can be provided with vibration balancing ballast box (14), regulate by counterweight, make sieve ship two ends vibration balancing unanimity.

The utility model, particularly its sieve ship partial design is reasonable, compact conformation, the screening of employing slope climbing type, the sieving and grading that adapts to multiple material of different grain size has overcome the drawback that the existing equipment screening is skipped a grade, and has improved the accuracy rate and the production efficiency of screening greatly, it is many once to sieve specification, is present a kind of comparatively desirable granule materials sieving and grading equipment.
