Detailed Description
The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.
Referring to fig. 1 to 9, the present embodiment discloses an adjustable grid 6 type circular large-grained seed grading device, which includes a box 1. The side walls of the left side and the right side of the box body 1 are respectively provided with arc-shaped grooves 3, the two arc-shaped grooves 3 are arranged in a bilateral symmetry manner, the left side wall and the right side wall of the box body 1 are respectively and fixedly provided with mounting strips 4 above the corresponding arc-shaped grooves 3, the mounting strips 4 are provided with a plurality of mounting holes 5, the mounting holes 5 are arranged in a row along the front-back direction, and the mounting holes 5 on the mounting strips 4 are uniformly distributed along the front-back direction at intervals; span in two arc walls 3 and be provided with many bars 6, many bars 6 set up side by side and leave the clearance between the adjacent bar 6, both ends stretch out respectively outside two arc walls 3 and upwards bending type become side direction bending segment 7 about every bar 6, a plurality of side direction bending segments 7 of many bars 6 homonymies couple together through an regulating plate 8, it has a plurality of regulation holes 9 to open on the regulating plate 8, a plurality of regulation holes 9 are arranged into one row along the fore-and-aft direction, a plurality of regulation holes 9 on the regulating plate 8 are along the even distribution in fore-and-aft direction interval, the centre-to-centre spacing of two adjacent regulation holes 9 is greater than the centre-to-centre spacing of two adjacent mounting holes 5. A plurality of side direction kinks 7 pass a plurality of regulation holes 9 on the regulating plate 8 respectively, 7 upper ends of the side direction kinks at every 6 both ends of grid inwards buckle and form couple 10, couple 10 of many grid 6 and the cooperation that corresponds 5 one-to-one of a plurality of mounting holes on the side mounting strip 4, 6 both ends of every grid insert respectively through couple 10 to the mounting hole 5 on the mounting strip 4 of both sides in, through the upper and lower position of adjustment regulating plate 8, thereby adjust the distance between two adjacent grid 6, realize the classification to different size range seeds. The adjusting plate 8 is adjusted upwards, so that the distance between the adjacent grid bars 6 is increased; the adjusting plate 8 is adjusted downwards, and the distance between the adjacent grids 6 is reduced.
The inner cavity of the box body 1 is also provided with a stirrer 11, and the stirrer 11 is positioned above the grid bars 6 and used for stirring seeds in the inner cavity of the box body 1. The agitator 11 includes an agitation shaft 12 and a plurality of blades 13 provided on the agitation shaft 12. Through motor drive agitator 11 positive and negative rotation for the seed is stirred to the seed that needs the separation in hopper 2 to blade 13 swing left and right sides, thereby realizes the abundant separation to the seed, avoids hierarchical in-process seed jam bars 6 clearances simultaneously.
Hopper 2 that 1 top of box was equipped with the flaring of top, 2 bottoms downwardly extending of hopper to a plurality of grids 6 upper surfaces, and both ends are located between the grid 6 of foremost and the grid 6 of rearmost end all the time around 2 bottoms of hopper, and the effect that sets up like this is: when the distance between the grid bars 6 is adjusted, the distance between the grid bars 6 at the foremost end and the front side wall of the box body 1 and the distance between the grid bars 6 at the rearmost end and the rear side wall of the box body 1 are greatly changed, and if the classified materials fall down from the gap between the grid bars 6 at the foremost end and the front side wall of the box body 1 and the gap between the grid bars 6 at the rearmost end and the rear side wall of the box body 1, the classification is inaccurate. And laminate almost with bars 6 upper surface when 2 bottoms of hopper, and both ends are located between bars 6 of foremost and bars 6 of rearmost end all the time around 2 bottoms of hopper, when adjusting bars 6 clearance during hierarchical, 2 end opening are in the effective hierarchical within range of bars 6 all the time under the hopper 2, can avoid hierarchical material to spill from the lateral wall clearance before foremost bars 6 and box 1, and lateral wall clearance behind rearmost end bars 6 and box 1, influence hierarchical effect.
Wherein, the bottom of the box body 1 is open, a plurality of grid bars 6 are used as the bottom, and a material collecting groove is arranged below the box body 1 during classification and used for collecting separated materials. The bottom of the side wall of the box body 1 is also provided with a lead-in gap 14 communicated with the arc-shaped groove 3 so as to facilitate the installation of the grid 6.
The position of adjusting plate 8 is adjusted earlier before hierarchical, then puts into hopper 2 with the seed, and the starter motor, the motor drive 11 actions of agitator realize the stirring to the seed in hopper 2, utilize the clearance between the adjacent grid 6 to select separately the seed, and the stirring of cooperation agitator 11 makes the seed that accords with hierarchical size scope in the hopper 2 by the abundant separation. And the adjusting plates 8 are sequentially adjusted from top to bottom according to the grading requirement, so that seeds with different size ranges can be separated batch by batch, and the continuous and stepless adjustment of grading parameters is realized. The sorting quality and efficiency of the circular large-grain seeds are improved, the labor amount and the labor intensity are reduced, meanwhile, continuous stepless adjustment can be realized according to the requirement of the seed grading size, and the adaptability and the use flexibility of the grading device are further improved. The problems of low grading efficiency, limited grading range, poor operation flexibility and adaptability and the like caused by the fact that grading components need to be replaced in the use of the conventional grading device are solved.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
