Detailed description of the invention

Below in conjunction with drawings and Examples the present invention it is further elaborated and illustrates. In the present invention, the technical characteristic of each embodiment is not under having conflicting premise, all can carry out respective combination.

As it is shown in figure 1, the casing of a generally combination of the electronic soil sieve of Horizontal drum type. It mainly includes segregation apparatus 1, screen cloth 2, screen cloth fixed disk 3 and motor 4. Screen cloth fixed disk 3 is directly fixed on motor 4, and is driven rotation by motor 4, is used for driving screen cloth. As it is shown on figure 3, screen cloth 2 is cylindrically, can be processed by hard material integration. 2 one end face openings of screen cloth are not closed. It is circumferentially fixed with the first arc square bar 10 and the second arc square bar 11, is used for being detachably secured to screen cloth fixed disk 3. First arc square bar 10 and the second arc square bar 11 there is bolt hole 14. As it can be seen in figures 5 and 6, the card of corresponding screen cloth fixed disk 3 is provided with first crack the 12, second crack 13 matched with it. First arc square bar 10 and the second arc square bar 11 can be inserted directly in first crack the 12, second crack 13, be screwed into screw, be fixed in by bolt hole 14, it is necessary to the dismounting screw that makes directly to back-out takes off. The degree of depth of bolt hole 15 reaches below crack 1cm to 2cm. Owing to soil needs to load in screen cloth before fixing, therefore as shown in Figure 4, the untight cylindric screen cloth set 15 in screen cloth 2 outer sheath one end is needed in advance. Screen cloth set 15 is except opening part, and all the other are both needed to airtight.

Segregation apparatus 1 is used for covering in outside screen cloth 2, and collects the pedotheque sifted out. As in figure 2 it is shown, segregation apparatus 1 is made up of the trapezoidal carrying 6 of cylinder 5 and bottom, cylinder 5 one end is not closed, and the other end is hinged with cylinder door 7, and between cylinder 5 and cylinder door 7, logical first connector 8 (such as hasp etc.) is fixed. Both sides You Liangge slope 17 in cylinder 5, arranges detachable dust collecting trough 9 bottom slope 17, for collecting the soil due to gravity fall. The untight one end of cylinder 5 airtight is fixed on motor 4 by the second connector 16 is detachable. Installing under state, it is internal that screen cloth 2 is arranged at cylinder 5. The assembling process of whole device is as shown in Figure 7.

In present embodiment, motor 4 is vibrating motor, it is possible to further make the soil particle of blocking sieve aperture drop, thus improving screening efficiency.

Based on said apparatus, present invention also offers a kind of sieve indigenous method using the electronic soil sieve of described Horizontal drum type, step is as follows:

The screen cloth 2 selecting suitable order number is put in screen cloth set 15, then adds the soil needing to sieve in screen cloth 2, notes the bottom that soil is layered on screen cloth 2 as far as possible, makes soil touch greater area of screen cloth as far as possible; Being overlapped at screen cloth by screen cloth 2 is fixed on screen cloth fixed disk 3 under the parcel of 15; It is fixed on airtight for untight for cylinder 5 one end on motor 4 again, opens cylinder door 7 and take out screen cloth set 15, then closed cylinder door 7; Open motor 4, screen cloth 2 is rotated along with screen cloth fixed disk 3, soil particle constantly rolls in screen cloth or rotates under centrifugal action, enter in the segregation apparatus 1 outside screen cloth 2 from sieve screen apertures less than the soil particle of mesh, be directly entered under gravity subsequently or slip in dust collecting trough 9 along slope 17; Closing motor 4, screen cloth 2 stops the rotation, and extracts dust collecting trough 9 out, it is thus achieved that the soil of required particle diameter from segregation apparatus 1. Then turn on the first connector 8 and the second connector 16, separate motor 4 and segregation apparatus 1, the bolt in bolt hole 14 is screwed out, take out screen cloth 2, open cylinder door 7 by the first connector 8, whole device and screen cloth 2 are cleaned with hairbrush.

After electric motor starting, can constantly repeat the state of high speed rotating after first low speed rotation. In low speed rotation process, the soil particle in screen cloth is the state constantly rolled. And in high-speed rotation, soil particle carries out circular motion along with screen cloth, under centrifugal action, granule is easier to be thrown out of screen cloth. And in soil particle the most easily blocking sieve aperture be the diameter granule slightly larger than sieve diameter, this partial particulate can enter sieve aperture reluctantly, but owing to diameter is slightly larger, the resistance therefore dropped is bigger. And when, under low speed rotation state, soil particle in constantly rolling condition, after entering a screen area, is positioned at undermost fine particle and is just screened out in screen cloth. And in rolling process, new fine particle constantly fills into again orlop, thus realizing continuous print screening. And after low speed rotation a period of time, the sieve aperture of part screen cloth may be blocked by direct, therefore motor high speed rotating, it is possible to use the soil particle in sieve aperture is thrown away by centrifugal force, improves screening efficiency.

Embodiment described above is the one preferably scheme of the present invention, and so it is not intended to limiting the invention, the technical scheme that all modes taking equivalent replacement or equivalent transformation obtain, and all falls within protection scope of the present invention.
