Detailed description of the invention

If Fig. 1 is to shown in 5: clear device at the beginning of a kind of feedstuff, including the big miscellaneous screening machine 1 being sequentially connected with, prime drag conveyor 2, little miscellaneous screening machine the 3, first conveying worm 4 and rear class drag conveyor 5, prime drag conveyor 2 is used for grain hoisting to eminence.

Big miscellaneous screening machine 1 includes housing 101, a free bearing 107 it is respectively welded on one in the corner of housing 101, four lower free bearings 108 it are fixed with on ground below housing 101, four hydraulic spring grease cups 105 it are provided with between housing 101 and ground, the two ends of hydraulic spring grease cup 105 are respectively hinged on a free bearing 107 and lower free bearing 108, the first through hole 109 is offered in the middle part of housing 101, the upper surface of the first through hole 109 is provided with screen cloth 102, housing 101 is provided with vibrator 104, screen cloth 102 is positioned at directly over the charging aperture of prime drag conveyor 2, in the specific implementation, upper three pieces of baffle plates 103 can be welded and fixed along the edge of housing 101 upper surface, baffle plate 103 is possible to prevent grain to run out of housing 101；After grain (such as Semen Maydis) is poured on screen cloth 102, open vibrator 104, the granule that particle diameter is less than screen cloth 102 aperture can drop in the charging aperture of prime drag conveyor 2 through screen cloth 102, by prime drag conveyor 2 by transport after grain hoisting to eminence to little miscellaneous screening machine 3, and the particle diameter therein impurity bigger than screen cloth 102 aperture can be stayed on screen cloth 102, after grain is sieved, it is possible to use besom is by the big miscellaneous removing on screen cloth 102；

Little miscellaneous screening machine 3 includes the cube shaped screening case 31 made with Plate Welding, interlock the most successively at screening case 31 both sides inwall and be provided with multiple screening unit 32, described screening unit 32 includes that what the downward-sloping withdrawable sieve plate 321 being inserted in screening case 31 and being inclined upwardly was fixed in screening case 31 connects miscellaneous plate 322, the one end connecing miscellaneous plate 322 is supported on the lower surface of sieve plate 321, by screening case 31 outer wall, sieve plate 321 and connect miscellaneous plate 322 and surround prism-shaped material stock cavity 323, screening case 31 outer wall offers second through hole 311 being in communication with the outside by material stock cavity 323；

The diameter of the upper sieve aperture of sieve plate 321 is less than the particle diameter of grain, after grain is fallen on sieve plate 321, the impurity less than grain particle diameter can pass in the material stock cavity 323 that sieve plate 321 falls into, discharge from the second through hole 311 again, in actual production, the sieve plate 321 of polylith difference sieve diameter can be made, make feedstuff needing the grain (such as sorghum rice) that Sieving and casing is less, can be extracted out in screening case 31 by sieve plate 321, the sieve plate 321 changing small-bore is the most permissible；

The connection of screening case 31 upper end is at the discharging opening of prime drag conveyor 2, the connection of screening case 31 lower end is at the charging aperture of the first conveying worm 4, grain after first conveying worm 4 will be screened by little miscellaneous screening machine 3 is transported to rear class drag conveyor 5, by rear class drag conveyor 5, grain is being transported to next feed manufacturing unit, such as pulverizer.

In the lower end of housing 101, material guiding hopper 106 is installed, material guiding hopper 106 is the pipeline of the truncated rectangular pyramids shape having four pieces of trapezoidal galvanized iron sheet rivetings to make, thicker one end is riveted on the lower surface of housing 101, thinner one end is towards the charging aperture of prime drag conveyor 2, after grain is screened by screen cloth 102, grain can be flowed in prime drag conveyor 2 along material guiding hopper 106.The effect of material guiding hopper 106 is to be imported to by grain in prime drag conveyor 2 smoothly, and avalanche to outside prime drag conveyor 2, is also possible to prevent on ground, other impurity enters into prime drag conveyor 2 simultaneously because housing 101 vibrates to prevent grain.

Being installed with positive stop strip 324 in the end of sieve plate 321, when sieve plate 321 is inserted in screening case 31, positive stop strip is resisted against on the outer wall of screening case 31, and positive stop strip 324 can play and sieve plate 321 is carried out spacing effect, prevents sieve plate 321 from falling to sieve in case 31.

Screening case 31 be respectively provided on two sides with one group of impurities removal part 33, described impurities removal part 33 includes passage 331 and the second conveying worm 332, passage 331 is sieving on case 31 side the second through hole 311 by a downward-sloping square pipe connection, the charging aperture of the second conveying worm 332 is positioned at the lower section of passage 331 mouth of pipe, impurity in material stock cavity 323 is because gravity is flowed in passage 331, impurity is transported to the second conveying worm 332 by mozzle, and the second conveying worm 332 focuses on impurity is transported to appointed place.

The effect of impurities removal part 33 is: when the impurity in material stock cavity 323 is discharged from the second through hole 311, can produce dust, impurity then can be concentrated by impurities removal part 33, prevents dust from entering in air and pollutes environment.

Screening case 31 upper end import connects the discharging opening at prime drag conveyor 2 by the first expansion joint 302, the lower end outlet of screening case 31 connects the charging aperture at the first conveying worm 4, the first expansion joint 302 and the second expansion joint 303 by the second expansion joint 303 can be so that installing screening case 31.

Work process of the present utility model: after grain being poured in big miscellaneous screening machine 1, open vibrator 104, the impurity that particle diameter is bigger than grain is sieved out by big miscellaneous screening machine 1, grain after being sized enters in prime drag conveyor 2 by material guiding hopper 106, grain is transported in little miscellaneous screening machine 3 by prime drag conveyor 2, grain can roll screening at each piece of sieve plate 321 in little miscellaneous screening machine 3 from top to bottom, the impurity making particle diameter in grain less is screened in material stock cavity 323, impurity in material stock cavity 323 is concentrated by impurities removal part 33 again, it is sized clean grain and enters into the first conveying worm 4, it is transported to rear class drag conveyor 5 by the first conveying worm 4, grain is transported to next feed manufacturing unit by rear class drag conveyor 5.

This utility model is wanted can effectively get rid of the impurity such as the rubble in grain or dregs in sum, it is ensured that feedstuff remaining production equipment properly functioning.
