Technical field

The utility model belongs to agricultural equipment field, and in particular, to a kind of seed screening machine.

Background technique

It needs to screen seed in agricultural planting, be needed at this time using seed screening machine, traditional seed screening Machine, can not directly remove the light sundries in seed, and screening and classification process are not thorough.The seed percentage of impurity filtered out in this way Height, not only seeding quality is poor, also will affect seed sprouting and growth and development.In addition, in existing seed screening plant, sieve material The selection of material is generally metallic sieve and stainless steel mesh, when seed falls to screen surface by feeding inlet, touches with sieve It hits, be easy to cause the surface of the seed damaged, influence seed quality.

Utility model content

In order to solve the problems, such as that impurity of seeds degree is high in the prior art, the utility model provides a kind of seed screening machine, institute Distance and the method for increase seed flow direction that device is flowed by extending seed in sieve are stated, in screen material, shape structure It makes and improves, in conjunction with vibration screening, improve the degree finely screened, reduce percentage of impurity.

To achieve the goals above, the utility model use the specific scheme is that

A kind of seed screening machine, including rack, the rack top are fixed with column；Case is equipped with above the column Body；Z-shaped sieve is set in the cabinet, the two sides of the sieve are equipped with skewback；It is equipped with and puts in the top of described sieve one end Hopper, the other end are connect by the discharge port on cabinet with discharge bucket；The sieve is higher than close to one end of drain hopper close to out Hopper one end；Vibration component is equipped with below the cabinet；The vibration component includes motor, is connected to motor belt wheel, bias Axis, with the vibrating arm of eccentric axis connection, the vibrating mass being connect with vibrating arm；The vibrating mass is connect with the bottom of box；The case It is connected between body bottom and rack by buffer spring.

It is advanced optimized as to above scheme, the drain hopper is connected on the rack by support frame.

It is advanced optimized as to above scheme, the column top is equipped with rubber mat plate, works as a buffer.

It is advanced optimized as to above scheme, the sieve passes through the sieve being arranged between sieve and cabinet inner bottom surface Net steady rest is fixed.

It is advanced optimized as to above scheme, the sieve is to combine then to beat using acrylic board and cotton canvas Hole is made, and increases the frictional force that seed and its sundries flow on sieve compass screen surface, effectively reduces breakage rate.

It is advanced optimized as to above scheme, the screen bottom is equipped with leakage preventing layer, prevents seed and impurity from passing through The sieve pore of sieve leaks down.

The utility model has the advantages that

1, seed screening machine described in the utility model flows seed on sieve by regular vibration, sharp in flowing Separation with the realization of different sizes of impurity frictional force or quality to impurity, improves the degree finely screened.Using extension kind The method of distance and increase seed flow direction that son is flowed in sieve, improves on screen material, configuration, can Solve the problems, such as that impurity of seeds degree is high.It is " Z " font by setting sieve contour structures, extends screening of the seed on sieve Journey keeps screening more thorough；Skewback is added in sieve two sides, increases seed Three-dimensional Flow effect, improves the degree finely screened, drop Low percentage of impurity.

2, the utility model combines punching to be used as sieve using acrylic board and cotton canvas, and cotton canvas can be to whereabouts Seed generate buffer function, and increase the frictional force that seed and its sundries flow on compass screen surface, separated convenient for seed and impurity, Be also prevented from seed and acrylic board sieve direct collision simultaneously, effectively reduce breakage rate and percentage of impurity, and acrylic board have it is anti- The features such as impact force is strong, and the service life is long, and from heavy and light, recovery rate is high, easy to maintain, the economy of equipment can be reduced as screen material Consumption.

Specific embodiment

Below in conjunction with the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear, complete Site preparation description.

A kind of seed screening machine, as shown in Figure 1, including rack 1, the 1 top both ends of rack are equipped with column 16；It is described Cabinet 5 has been installed above column 16；16 top of column is equipped with rubber mat plate 2, plays certain buffer function；The cabinet Sieve 15 is equipped in 5, as shown in Fig. 2, the sieve 15 is in Z-shaped, the both ends of the sieve 15 are each attached to the inside of cabinet 5 On face, the turning point on sieve 15 is fixed by sieve steady rest 8 and 5 inner bottom surface of cabinet；The two sides of the sieve 15 are equipped with oblique Panel 4, so that the sieve 15 of bottom and the skewback 4 of two sides constitute seed flow channel space；In described 15 one end of sieve Top is equipped with the drain hopper 6 for launching seed, and the other end is connected to the discharge port on cabinet 5, the discharge port peripheral hardware discharging Bucket 3；The drain hopper 6 is fixed by the support frame 7 being fixed in rack 1；15 slant setting of sieve, it is close in sieve 15 One end of drain hopper 6 is higher than close to 3 one end of discharge bucket, and left low and right high flows seed or so as shown in Figure 1, adds skewback 4 Make to flow before and after seed；Vibration component is equipped with below the cabinet 5, the vibration component work drives cabinet 5 to vibrate, makes seed Upper and lower slight vibration；The vibration component includes that motor 13, the belt wheel connecting with motor 13 9, eccentric shaft 10 and eccentric shaft 10 connect The vibrating arm 11 connect, the vibrating mass 12 being connect with vibrating arm 11；The vibrating mass 12 is fixedly connected with 5 bottom of cabinet；The case It is connected between 5 bottom of body and rack 1 by buffer spring 14.

The sieve 15 combines punching to be made using acrylic board and cotton canvas, and seed flows realization above sieve 15 Screening, impurity is leaked down by the mesh on sieve 15 in order to prevent, is equipped with leakage preventing layer in 15 bottom of sieve.

The course of work: starting motor 13, is acted on by the linkage of belt wheel 9, eccentric shaft 10, vibrating arm 11 and vibrating mass 12, Drive cabinet 5 vibrate up and down, while sieve 15 with cabinet 5 as slight up-down vibration；Seed by 6 vertical drop of drain hopper extremely On sieve 15 in cabinet 5 located directly below, 15 surface of sieve has one layer of cotton canvas, in seeds fall to 15 surface of sieve When certain buffer function is provided, avoid and 15 direct collision of acrylic board sieve, generate damaged.Sieve 15 is obliquely installed and increases If skewback 4 so that seed and light sundries flow on the compass screen surface of sieve 15, cotton canvas provides rubbing action when flowing. Due to the irregular contour of the sundries such as soil block, stone, cauline leaf, glume, and weight is slight, so flowing velocity is most slow, finally stops Stay in 15 front half section of sieve；Shrivelled or incomplete seed shape is defective, eventually settles at 15 middle section of sieve；And full grains Seed smooth-shaped is mellow and full, and flowing velocity is most fast, is finally flowed out by discharge bucket 3.15 slant setting left low and right high of sieve makes seed Left and right flowing, adding skewback 4 makes flowing before and after seed, and 5 lower section vibration component of cabinet drives cabinet 5 to vibrate, makes seed or more Slight vibration increases mobility of the seed in sieve 15, improves screening efficiency.

It should be noted that embodiment described above is interpreted as illustrative, rather than the utility model is limited Protection scope, the protection scope of the utility model are subject to claims.To those skilled in the art, without departing substantially from Under the premise of the utility model in essence and range, this is still fallen within to some nonessential modifications and adaptations that the utility model is made The protection scope of utility model.
