Detailed Description

The present invention will be further explained below.

Example (b):

as shown in figure 1, a caking prevention device of chemical fertilizer screening machine, including frame 1, the workbin 2 of setting in frame 1, workbin 2 is the column setting, and feed inlet 21 has been seted up at the top of workbin 2, and the diapire slope setting in the workbin 2, and the discharge gate 22 has been seted up to the lower extreme of slope to be convenient for the chemical fertilizer leaves workbin 2.

Vertical lifter 3 is worn to be equipped with in the activity of the central point department of the diapire of workbin 2, lifter 3 is located the outer one end of workbin 2 and is provided with driving piece 4, driving piece 4 includes auxiliary rod 41 in this embodiment, eccentric wheel 42 and be used for driving eccentric wheel 42 pivoted motor 43, the both ends of auxiliary rod 41 rotate with lifter 3 and eccentric wheel 42 respectively and are connected, when eccentric wheel 42 rotates, auxiliary rod 41 pulls lifter 3 and is reciprocating motion in vertical direction, still can overlap on the lifter 3 in other embodiments and establish the spring, the both ends of spring are connected with workbin 2 diapire and lifter 3 respectively, with the motion of supplementary lifter 3.

A circle of flanges 23 with triangular cross sections are arranged on the inner side wall of the material box 2, a conical extrusion block 5 is arranged at one end of the lifting rod 3, which is located in the material box 2, and most of the extrusion block 5 is located below the flanges 23. The flange 23 is arranged parallel to the two side walls of the squeezing block 5 that are close to each other, the smallest distance between the two side walls being the diameter of a single fertilizer granule in this embodiment. The cambered surface of extrusion piece 5 is provided with a plurality of vertical projections 51, and a plurality of projections 51 enclose into the ring form around the axis of extrusion piece 5, and the clearance between adjacent projection 51 is greater than the diameter of fertilizer granule and is less than the diameter setting of twice fertilizer granule to make single fertilizer granule pass through, the fertilizer of caking stops to wait for between extrusion piece 5 and flange 23 to be extruded. The flange 23 is provided with a groove 231 for accommodating the convex column 51, and in this embodiment, one end of the convex column 51 is always accommodated in the groove 231, so as to prevent the agglomerated fertilizer from leaving the extrusion block 5 from a gap between the convex column 51 and the flange 23 in the movement process of the extrusion block 5.

The top of the extrusion block 5 is connected with a conical separation block 53 through a vertical connecting rod 52, the separation block 53 is positioned above the flange 23, and the separation block 53 can close the opening formed by the annular flange 23 when the lifting rod 3 descends to the lowest point.

The working process is as follows:

the operator pours the fertilizer into the hopper, the lifting rod 3 is located at the lowest position, and the separating block 53 seals the opening formed by the flange 23, so that the fertilizer is temporarily stored in the material box 2.

The motor 43 rotates to drive the lifting rod 3 to reciprocate in the vertical direction. The lifting rod 3 rises, a gap is formed between the separating block 53 and the flange 23, and the fertilizer above the separating block 53 reaches the gap between the connecting rod 52 and the flange 23 from the opening formed by the flange 23. When the lifting rod 3 descends, fertilizer between the connecting rod 52 and the flange 23 enters a gap between the flange 23 and the extrusion block 5, and the separating block 53 gradually closes an opening formed by the flange 23 to prevent excessive fertilizer from being piled up in the gap between the flange 23 and the extrusion block 5. At the moment, single fertilizer particles roll along the inclined side walls of the extrusion blocks 5 and leave the extrusion blocks 5 from gaps among the convex columns 51 to reach the discharge port 22, and the agglomerated fertilizer is blocked between the extrusion blocks 5 and the flanges 23 by the convex columns 51. Then the lifting rod 3 rises, the distance between the extrusion block 5 and the flange 23 is reduced, the caked fertilizer is dispersed under the extrusion effect, and the crushed caked fertilizer leaves the extrusion block 5 from the convex column 51 to the discharge port 22 when the lifting rod 3 descends. The process of crushing the agglomerates is simple and convenient and is easy to implement.

The principle and the implementation of the present invention are explained herein by using specific examples, and the above description of the embodiments is only used to help understand the method and the core idea of the present invention; while the invention has been described in terms of specific embodiments and applications, it will be apparent to those skilled in the art that numerous variations and modifications can be made without departing from the spirit and scope of the invention as defined in the appended claims.
