Abstract

The utility model discloses an adjustable multipurpose sifter for seed selection which is used for farm families to select the seed and is composed of a sifter frame with an eyelet and a moving sifter plate which is arranged at the bottom of the sifter frame and regulates the size of the eyelet of the sifter frame through a spring and a screw nail. The adjustable multipurpose sifter for seed selection has the advantages of simple structure and easy processing and manufacture and the operation of the adjustable multipurpose sifter is simple than a common flat sifter; the mastery is easy, a household only purchases a sifter which can be used for sifting a plurality of kinds of seed granules with different sizes and the application scope is wide.

Description

Adjustable multi-purpose sifter for seed selection

The utility model relates to a kind of regulating type and how to sieve with seed selection, belongs to the instrument of peasant household's seed selection usefulness.

During peasant household's seed selection at present, adopt the sieve of thin bamboo strips used for weaving establishment more,, still can not avoid the difference of kind of intergranular, some underproof kind grains have also been chosen the output when this certainly will influence plant growth uniformity and results because of eyelet is irregular.And all kinds of kind grains are not of uniform size, and it is not enough being limited to a sieve.

Task of the present utility model is to solve the deficiency of above-mentioned seed selection sieve, provides a kind of regulating type how with the seed selection sieve, only with a sieve, just can screen greatly to broad bean (having another name called lima bean), sword bean, little of some all grains such as vegetable seed, improved the availability and the choicest quality of sieve greatly.

This task realizes by following approach: how this regulating type the sieve plate of screen frame body and band sieve aperture is made of with the seed selection sieve, and the sieve aperture spread pattern on the sieve plate is; The holes of adjacent two row are staggered, and sieve aperture be oval (or rhombus, prismatic, approximate ellipsoidal), hole suitable for reading big, and end opening is smaller, and sieve aperture is convex surface on every side above the sieve plate, is the plane below.On the screen frame body of sieve plate bottom, fluted on the two side parallel with the sieve aperture major axis, on the two side vertical through hole is arranged with groove, in groove, insert 1～2 two-dimensional activity sieve plate, an end and the hot pressing of screen frame body sidewall on the active sieve plate (or riveting, weldering) have spring to be connected, other end hot pressing (or riveting, weldering) has screw rod, link to each other the end active sieve plate with screw rod than the short 17～20mm of sieve plate, screw rod passes hole on the sidewall, screw on the butterfly nut, by regulating the butterfly nut, the control active sieve plate moves back and forth in groove.Sieve aperture spread pattern on the active sieve plate is: walk crosswise and be one group by a macropore and 1～2 aperture and be arranged in order, and the major axis of macropore and the minor axis of aperture are on a center line, perpendicular row also is to be one group by a macropore and 1～2 aperture to be arranged in order, be that adjacent two in the ranks macropore and aperture are staggered, macropore is the same with the hole on the sieve plate big, aperture also is oval (or rhombus, prismatic, approximate ellipsoidal), and the circular arc on the aperture minor axis (or angle) is consistent with the circular arc (or angle) of macropore longitudinal end.How regulating type can be circle or rectangle with the seed selection sieve, screen frame body, sieve plate, active sieve plate, and available plastic injection-moulded or metal stamping forms.

Described in detail below in conjunction with an embodiment of the present utility model.

Fig. 2 is the structural representation of active sieve plate

How regulating type sieves with seed selection, sieve plate 2 by screen frame body 1 and band sieve aperture is formed, sieve aperture spread pattern on the sieve plate 2 is, the holes of adjacent two row are staggered, and sieve aperture 3 be oval, the hole suitable for reading greatly, end opening is smaller, being convex surface around the sieve aperture 3 above the sieve plate 2, is the plane, below on the screen frame body of sieve plate 2 bottoms, on the two side parallel fluted 4 with the sieve aperture major axis, through hole 8 is arranged on the two side vertical with groove, insert two two-dimensional activity sieve plates 5 in groove 4, an end has spring 6 to be connected with the hot pressing of screen frame body sidewall on the active sieve plate 5, other end hot pressing has screw rod 7, link to each other end active sieve plate 5 with screw rod 7 than sieve plate 2 short 17mm, screw rod passes hole 8 on the sidewall, screws on butterfly nut 9, by regulating butterfly nut 9, control active sieve plate 5 moves back and forth in groove 4, when the hole transfers to required size, promptly can be used for seed selection.Sieve aperture spread pattern on the active sieve plate 5: walk crosswise a macropore one aperture and be one group and be arranged in order, and the major axis of macropore and the minor axis of aperture are on a center line, perpendicular row also is that a macropore one aperture is one group and is arranged in order, be that adjacent two in the ranks macropore and aperture are staggered, macropore is the same big with the hole on the sieve plate 2, aperture 10 also is oval, and the circular arc on the aperture minor axis is consistent with the circular arc of macropore longitudinal end.During assembling, two active sieve plates are put upside down and are inserted in groove 4.How this regulating type sieves with seed selection is circular, screen frame body 1, and sieve plate 2, active sieve plate 5 is used injection molding.If how to connect oscillator and motor for regulating type with the seed selection sieve, can constitute the mechanical sieve selection tool, the classification of food supply food machining sector is used.Also the hole on the active sieve plate all can be processed into aperture (or macropore), be used for screening than small sized seeds (or big grain).

This adjustable multi-purpose sifter for seed selection, simple and reasonable, processing and fabricating is easy, and is easy and simple to handle, and other only needs a family to buy a sieve, just can be used for the screening of the big small sized seeds of several difference, and is economical and practical. And be convex surface because of around the sieve plate 2 top sieve apertures, need only shake screen frame, plant very easily landing from the hole of grain, more easy and simple to handle than general horizontal screen, be easy to grasp, widely applicable.

Claims

1, how a kind of regulating type sieves with seed selection, sieve plate 2 by screen frame body 1 and band sieve aperture is formed, it is characterized in that: the sieve aperture spread pattern on the sieve plate 2 is, the hole of adjacent two row is staggered, sieve aperture 3 is oval (or rhombus, prismatic, approximate ellipsoidal), hole suitable for reading big, end opening is smaller, be convex surface above the sieve plate 2 around the sieve aperture 3, be the plane below, on the screen frame body of sieve plate 2 bottoms, on the two side parallel fluted 4 with the sieve aperture major axis, through hole 8 is arranged on the two side vertical with groove, insert 1～2 two-dimensional activity sieve plate 5 in groove 4, an end and screen frame body sidewall pad are pressed (or riveting on the active sieve plate 5, weldering) there is spring 6 to connect, other end hot pressing (or riveting, weldering) screw rod 7 is arranged, link to each other end active sieve plate 5 with screw rod 7 than sieve plate 2 short 17～20mm, screw rod passes hole 8 on the sidewall, screws on butterfly nut 9, by regulating butterfly nut 9, control active sieve plate 5 moves back and forth in groove 4.
