[0029] Working principle:

[0030] Mixing and discharging work in the production of blended fertilizers:

[0031] When it is necessary to mix the blended fertilizer, pour the blended fertilizer into the opening processed at the upper end of the tank body 4, then connect the power lines of the two third motors 5 to the control panel at the same time, and connect the external power supplies of the two third motors 5 at the same time, the two third motors 5 start and drive the respective rotating shafts 11 to rotate relative to each other through the bearings in the tank body 4, the relative rotation of the two rotating shafts 11 drives the multiple paddles installed on the surface to rotate relative to each other, so that the blended fertilizer can be mixed, and when the blended fertilizer is mixed, the two third motors 5 stop rotating, and then open the valves installed on the two discharge ports 7, connect the external power supply of the first motor 102, the first motor 102 starts and drives the worm 103 to rotate in the first box body 101 through the bearing, the rotation of the worm 103 drives the worm wheel 104 to rotate in the first box body 101, and the worm wheel 104 drives the worm 104 to rotate. The movable gear 105 rotates clockwise, and the gear 105 rotates clockwise to drive the rack 106 to move to the right, thereby driving the square plate 107 to slide to the right in the slideway processed on the inner wall of the first box body 101 through the rack 106, and the square plate 107 slides to the right through the slide groove processed on the surface and the raised cylinder on the surface of the vertical rod 108, driving the vertical rod 108 to slide upward in the first box body 101, and the vertical rod 108 slides upward through the raised cylinder on the surface and the slide groove processed on the surface of the horizontal plate 6 to drive the horizontal plate 6 to move upward, thereby driving the tank body 4 to move clockwise around the pin shaft between the two vertical rods 8 as the center through the horizontal plate 6, so that the tank body 4 can be tilted to the right by movement, and the mixed fertilizer in the tank body 4 will flow out through the two discharge ports 7 to the top of the filter screen 10 in the third box body 9, and the mixed fertilizer can be discharged by movement.

[0032] Fertilizer blending filtration work:

[0033] After all the blended fertilizer in the tank body 4 flows out, the external power supply of the second motor 202 is turned on, and the second motor 202 starts to drive the reciprocating screw 203 to rotate through the bearing in the second box body 201. The rotation of the reciprocating screw 203 drives the screw nut 204 to slide back and forth in the slideway processed on the inner wall of the second box body 201, and the two cross bars 205 are driven to slide back and forth in the second box body 201 through the screw nut 204, so that the third box body 9 is driven to slide back and forth in the two sliding surfaces processed on the surface of the bottom plate 3 through the multiple rollers installed at the bottom through the two cross bars 205. The reciprocating motion can shake and loosen the blended fertilizer accumulated on the top of the filter screen 10. At this time, the wet and agglomerated blended fertilizer 10 will remain on the filter screen 10, and the qualified ones will flow to the lower end of the third box body 9 for collection. When the blended fertilizer is filtered, the sliding door installed on the surface of the third box body 9 is opened for collection.
