Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seed flotation equipment, in particular to a particle seed screening system. Background Art
[0002] In agricultural production practice, screening for improved seeds is key to ensuring smooth seed production. Because some seeds with higher densities have a density greater than that of water, they can be screened using flotation, which is simple, efficient, and low-cost. Specifically, the seeds to be screened can be placed in a box filled with clean water. If the seeds are normal and solid, they will sink downwards, while some empty seeds will float up because their density is less than that of water, thereby achieving separation. The floating part is fished out, and then the water in the box is poured out and filtered to obtain all solid improved seeds. In actual production, the seeds obtained by this screening method can only be guaranteed to be solid, but there will be problems with large differences in particle size. At the same time, some solid impurities (such as pebbles) will also be mixed in the seeds, so further screening is required, which further prolongs the overall screening time, thereby reducing the overall production efficiency to a certain extent. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a particle seed screening system, which solves the problem in the prior art that seeds after flotation may be mixed with solid impurities and have large size differences.
[0004] According to an embodiment of the present utility model, a particle seed screening system includes: a floating water tank for filling with clean water; an interception box, a plurality of first cross bars are arranged side by side at equal distances on the top surface of the interception box, a plurality of second cross bars are arranged side by side at equal distances on the bottom surface, and the distance between two adjacent first cross bars is greater than the distance between two adjacent second cross bars; support columns are also fixedly connected at the four corners of the bottom of the interception box, and the interception box can enter and exit the floating water tank and be placed in the floating tank through four support columns.
[0005] In the above embodiment, the interception box in the floatation tank is used for seeds to enter, and the distance between the first cross bars is larger, so that the seeds can enter smoothly. Some impurities that are too large (such as stones) will be intercepted on the first cross bar, and a second cross bar is also provided. The spacing between the second cross bars is smaller, which is used to allow smaller seeds to pass through, so that seeds of appropriate size are intercepted in the interception box, and then the interception box is taken out and the intercepted seeds are poured out. The seeds screened in this way may still contain a small amount of impurities of similar size, but compared with the existing technology, the amount of impurities has been greatly reduced, and the size is more uniform, so the efficiency can be further improved, solving the problem that the seeds after flotation in the existing technology may be mixed with solid impurities and have large size differences.
[0006] Furthermore, a stirring blade is rotatably provided at the bottom of the floating water tank, and a driving motor for driving the stirring blade to rotate around an axis is also provided outside the floating water tank.

[0012] Furthermore, both ends of the first crossbar are respectively engaged with the annular inclined surface.
[0013] Furthermore, a horizontal bar is fixedly connected between the two sides opposite to the higher side of the annular inclined surface.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] By setting the first cross bar and the second cross bar, larger impurities can be intercepted, smaller seeds can be screened out, and more seeds of appropriate size can be retained in the interception box. The interception box can be taken out and the intercepted seeds can be poured out. The seeds screened in this way may still contain a small amount of impurities of similar size, but compared with the existing technology, the amount of impurities has been greatly reduced, and the size is more uniform, so the efficiency can be further improved, solving the problem that solid impurities may be mixed in the seeds after flotation and the size difference is large in the existing technology.

DETAILED DESCRIPTION
[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0024] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present invention.
[0025] In an exemplary embodiment, Figure 1-5 As shown, this embodiment provides a particle seed screening system, which includes: a floating water tank 1 for filling with clean water; an interception box 2, a plurality of first cross bars 3 are arranged side by side at equal distances on the top surface of the interception box 2, and a plurality of second cross bars 4 are arranged side by side at equal distances on the bottom surface, and the distance between two adjacent first cross bars 3 is greater than the distance between two adjacent second cross bars 4; support columns 5 are also fixedly connected at the four corners of the bottom of the interception box 2, and the interception box 2 can enter and exit the floating water tank 1 and be placed in the floating tank 1 through the four support columns 5.
[0026] In the above embodiment, the interception box 2 in the floatation tank 1 is used for seeds to enter, and the distance between the first cross bars 3 is larger, so that the seeds can enter smoothly. Some impurities of too large size (such as stones) will be intercepted on the first cross bar 3, and a second cross bar 4 is provided. The spacing between the second cross bars 4 is smaller, which is used to allow smaller seeds to pass through, so that the seeds of appropriate size are intercepted in the interception box 2, and then the interception box 2 is taken out and the intercepted seeds are poured out. The seeds screened in this way may still contain a small amount of impurities of similar size, but compared with the existing technology, the amount of impurities has been greatly reduced, and the size is more uniform, so the efficiency can be further improved, and the problem that the seeds after flotation in the existing technology may be mixed with solid impurities and have large size differences is solved; specifically, an overflow pipe 6 can be connected to the upper side wall of the floatation tank 1, and the overflow pipe 6 is located above the interception box 2 (it can also be located above the overflow pipe 6 The water in the floating tank 1 can be discharged through the drain pipe 8 provided at the bottom (a valve is provided on the drain pipe 8 to control its on and off).
[0027] In a further exemplary embodiment, Figure 1 、 2 As shown in Figures 3 and 5, the upper side wall of the interception box 2 is curled inward to form an annular slope 9, and all the first cross bars 3 are respectively connected to the lower side of the annular slope 9. Specifically, the card groove 10 is arranged on the lower side of the annular slope 9, so that after the first cross bar 3 is engaged, an inward-concave interception groove is formed on the top surface of the interception box 2, which can effectively prevent the intercepted large impurities from diffusing to the periphery to the bottom of the floating tank 1; further, a cross bar 11 is fixedly connected between the two sides opposite to the higher side of the annular slope 9, and the interception box 2 can be easily lifted by the cross bar 11. At the same time, since the interception box 2 is connected from top to bottom, it will not be subject to excessive water resistance during the lifting and lowering process.
[0028] In a further exemplary embodiment, Figure 1 、 2As shown, in order to further improve the flotation efficiency, a stirring blade 12 is also rotatably provided at the bottom of the float tank 1, and a driving motor 13 is also provided outside the float tank 1 to drive the stirring blade 12 to rotate around the axis. At the same time, after the interception box 2 is placed, the second cross bar 4 can be higher than the stirring blade 12 due to the setting of the support column 5, so as to avoid the stirring blade 12 colliding with the second cross bar 4 during the rotation process; specifically, the driving motor 13 drives the stirring blade 12 to rotate so that the clean water is turned over, and the rotation speed is slow. After a period of stirring, it stops (such as 1 minute), so that unqualified seeds can float up faster; in more detail, support plates are fixedly connected to both sides of the bottom of the float tank 1. 14. The drive motor 13 is installed on one of the support plates 14. The float tank 1 is also rotatably installed with a rotating shaft 15 and the stirring blade 12 is fixedly connected to the rotating shaft 15. The rotating shaft 15 also rotates and extends to the bottom of the float tank 1 and is fixedly connected to a drive wheel 16. The rotating shaft of the drive motor 13 is fixedly connected to a drive wheel 17. A drive belt 18 is wound around the drive wheel 17 and the drive wheel 16. In this way, the drive motor 13 drives the stirring blade 12 indirectly. The drive wheel 17, the drive wheel 16 and the drive belt 18 can be similar drive belts and pulleys in the prior art. The drive motor 13 drives the drive wheel 17 to rotate, and then drives the drive wheel 16 to rotate through the drive belt 18.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
