Abstract

The utility model relates to a two-screen and one-frame type sorter, in which a screen frame is provided with an upper and a lower cleaning screen with different mashes, wherein, the upper screen plate is a louver screen, the top end of each screen petal is a curve whose radius of curvature is R, and the lower screen plate is a circular screen. Therefore, the utility model strengthens effectively the performance of the screen to push the broken haulm and enhances the cleaning effect, making the trash content meet the national requirement.

Description

Two-screen and one frame type sorter

The utility model relates to a kind of device in suspension type, the cleaning plant on the small-sized grain combine.

At present, small-sized suspension type grain combine vibratory sieve is because of being subjected to the restriction of cleaning unit's volume, only be designed to single-deck screen, thereby make that to clean effect often not ideal enough, be difficult to reach the requirement of the pertinent regulations of country, cause the user also to require one after another further to improve to clean function, improve and clean effect.

Because in, the sheller unit of small-sized mounted combine mostly is the axial-flow type nail tooth drum, and the volume of its clear grain formula is all less, just double deck screen can't be installed if resemble the combine of self-propelled threshing every layer of private separately screen frame (unit) of sieve.For solving this contradiction, through conscientiously research, repetition test has been designed to two kinds of sieves are installed in new structure on the same screen frame (unit) finally.

The purpose of this utility model, be design a kind of in, on the small-sized grain combine two kinds of multi-form sieve plates are divided the two-layer non-screen box formula new structure that is installed in simultaneously on the screen frame (unit) up and down.

The purpose of this utility model is achieved in that the sieve plate with two different sieve apertures is fixed on the same screen frame (unit), and the upper strata sieve plate is that the top has the curved surface lip(ped) sieve that radius of curvature is R, and lower floor's sieve plate is a round-hole mesh.

Fig. 2: upper strata sieve plate partial enlarged view.

Below by accompanying drawing embodiment of the present utility model is described in detail:

Fig. 1 ┄ ┄ installed threshing separator 2 ┄ ┄ slip paddy plate 3 ┄ ┄ blower fans 4 ┄ ┄ and put out cereal device 5 ┄ ┄ upper strata sieve plates 6 ┄ ┄ lower floor sieve plates 7 ┄ ┄ suspension rods 8 ┄ ┄ screen frame (unit)s 9 ┄ ┄ fork A ┄ ┄ tops to have radius of curvature be the R(curved surface) flap.As shown in the figure,

May you enjoy repose is loaded on the same screen frame (unit) eight for upper strata of the present utility model sieve plate 5 and lower floor's sieve plate 6,

And the top of upper strata sieve plate 5 each lip(ped) sieve sheet is that radius of curvature is the curved surface of R.Lower floor's sieve plate 6

Be round-hole mesh, fork 9 connects with screen frame (unit) 8, and suspension rod 7 connects with the thresher side plate.

Use this two sieves, one posture cleaning plant, be fixed on the same screen frame (unit) because the levels sieve aperture is inconsistent, only need a cover swing mechanism, utilize same amplitude and frequency that two-layer sieve plate is finished simultaneously and clean function, thereby make sieve be easy at work light foreign material such as broken cane are released the cleaning unit along compass screen surface.Light foreign material such as the broken cane of therefore effective minimizing are shaken off to lower screen, alleviate the load of lower screen, have improved and have cleaned effect.

Claims

1, in a kind of being installed in; on the small-sized suspension type grain combine two sieve one posture cleaning plant; be by installed threshing separator; slide paddy plate, blower fan, the compositions such as device and sorting screen of putting out cereal; it is characterized in that: cleaning screen is on the sieve plate by two different sieve apertures; following two-layer being separately fixed on the same screen frame (unit), screen frame (unit) connects with fork, and suspension rod connects with the side plate of thresher.

2, two sieves, one posture cleaning plant according to claim 1, it is characterized in that: the upper strata sieve plate is that the top has the curved surface lip(ped) sieve that radius of curvature is R, and lower floor's sieve plate is a round-hole mesh.
