The specific embodiment

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

As Fig. 1, Fig. 3, shown in Figure 5, the utility model is made up of frame 1, cylinder cleaning sieve 2, stone remover 3, stone remover 3 directly be contained in cylinder cleaning sieve 2 below, the charging aperture of cylinder cleaning sieve 2 grain grain discharging openings and stone remover is connected, screen drum 4 and outer screen drum 5 in cylinder cleaning sieve 2 is equipped with, guiding spiral 6,7 is housed respectively in interior screen drum 4 and the outer screen drum 5, feed conduit 8 stretches in the interior screen drum 4 of cylinder cleaning sieve 2 and is fixed on the screen drum cover 9, aspiration channel 10 is housed above the stone remover 3, and aspiration channel 10 links to each other with suspended hood 12 by flexible pipe 11.Eccentric rocker gear 13 and fish scale oscillating plate 14 are housed on the stone remover 3, and the interior screen drum of cylinder cleaning sieve 2 is a griddle, and outer screen drum is little hole sizer.The structure of stone remover is that the top is charging aperture and aspiration channel, and the middle part is a sieve nest, and sieve nest is supported on the frame by rocking bar, aspiration channel, charging aperture adopt artificial leather to be connected with the sieve nest of motion, the bottom is a support, and radial gear is positioned under the sieve nest, and it is reciprocating to drive sieve nest by eccentric ratio.Air draught mouth of pipe place on the frame is provided with oblique feed pipe, taps into down hopper, advances the flow of machine material by the spring pressure gate control, when the material in the feed hopper reach a certain height, overcomes the pulling force of spring according to its gravity, and bin gate is opened.Suspended hood under being flexible coupling and screen frame sealing and fixing, suspended hood is provided with observation window and AD.The front end of suspended hood is a Selected Room, and the air intake of Selected Room is controlled separately by the air door of its below, and the front end of Selected Room is a stone outlet hole 19, and the rear end of suspended hood is clean beam outlet 20.Whole sieve nest is by three rocking bars (three fulcrums) supporting, and the sieve nest middle part promptly has two eccentric ratios to drive on the sieve nest position of centre of gravity, and eccentric ratio has an eccentric shaft to drive.After motor drives the belt pulley rotation by driving-belt, do reciprocating linear motion even be in the eccentric shaft eccentric ratio of same phase place, making sieve nest simultaneously is the reciprocating motion by a small margin at center around rocking bar.

Operation principle

As shown in Figure 6, raw grain is imported in the interior screen drum 4 that horizontal axis rotates by throat-fed pipe 8, do relative slip with compass screen surface, under appropriate rotating speed, the grain grain passes internal layer screen drum 4 sieve apertures and enters in the outer screen drum 5, big assorted residing on internal layer screen drum 4 compass screen surfaces, and under the effect of guiding spiral 6, discharge from screen drum free end 15.After the grain grain of screen drum 4 compass screen surfaces enters in the outer screen drum 5 in passing, do relative slip with compass screen surface, under appropriate rotating speed, tiny mixing passed outer screen drum 5 compass screen surfaces, outside impurity outlet 16 discharge machines.The grain grain resides on outer screen drum 5 compass screen surfaces, and is discharging in the middle part of passage 18 enters stone remover from screen drum free end 17 under the effect of guiding spiral 7, because the double vibrations of gillis 14 makes material be covered with whole gillis 14 rapidly.Remove the segregation section of slabstone 14 at fish scale, because air stream is to the active force of the bed of material, fish scale removes the double vibrations of slabstone 14 in addition, advances the machine material and forms automatic classification rapidly, is divided into the half less last bed of material and bigger the sinking in following bed of material two parts of plate face of proportion that suspends of proportion.

The last bed of material is made up of proportion and the less relatively grain grain of floating velocity basically, it is covered in down on the bed of material, because air-flow effect vertically upward, normal pressure and frictional force between the upper and lower bed of material have been reduced simultaneously, thereby can make the bed of material under the effect of system inertia power and gravity tangential component, the following bed of material is a sliding surface, exports 20 with respect to going slabstone slowly to slide into clean grain downwards, outside the discharge machine.Be half suspend in the process that glides of the bed of material, the stone, the clod that are mixed in the grain are separated from the grain grain gradually, and enter the lower screen face.

The following bed of material is by stone, clod and a small amount of half grain grain that suspends are formed shoulder to shoulder.Because air flows the obstruction of the effect of the following bed of material being protruded the limit along the fish scale hole, the effect of the frictional force of the relative gillis of the following bed of material, therefore the bed of material can not be with last bed of material downslide down.Double vibrations along with sieve nest, the following bed of material is subjected to sieve nest motion and the inertia force that produces (because bed of material contact compass screen surface down, it has obtained the inertia force of bigger thrown direction from the vibration of gillis) and fish scale protrude the motive force on limit, progressively move to the sieve nest upper end, through collection sections and selected section, outside row's stone mouth 19 discharge machines.

The following bed of material is in the process that moves to the upper end, thickness of feed layer is attenuate gradually, the grain grain constantly reduces, wherein because pushing mutually of grain grain group at the beginning, upper layer material is to the extruding of layered material down, fail abundant come-up the grain grain then constantly half suspend enter the bed of material or with initiate heavy material transposition, thereby when arriving the collection sections end, contained grain grain is seldom.When stone shoulder to shoulder, clod during through selected section, selected section blowback air-flow can make a small amount of grain grain that is mixed in the stone shoulder to shoulder return collection sections, to run out of grain substantially in the row's of assurance stone.
