Fig. 1 and Fig. 2 are please referred to, the utility model embodiment provides a kind of floating grain discharging device 10 of intelligence, and the intelligence is floating Grain discharging device 10 includes discharge nozzle 100 and discharging ring 200.

The discharge nozzle 100 is hollow structure, and the discharge nozzle 100 includes discharging tube body 110 and multiple nozzles 120. The discharging tube body 110 includes feed inlet 112, sealing end 113 and tube wall 111,113 phases of the feed end 112 and the sealing end To setting, between the feed inlet 112 and the sealing end 113, the nozzle 120 is arranged described for the setting of tube wall 111 On tube wall 111, the nozzle 120 connects with the feed inlet 112.The hollow structure of the discharge nozzle 100 is for accommodating simultaneously Slurry is transmitted, slurry is transported in discharge nozzle 100 in delivery pump or under gravity, and is sprayed from the nozzle 120. One end of the discharging tube body is using 113 setting of sealing end, after being passed through the slurry from feed inlet 112, in discharging tube body Transmission in 110 pipeline, due to the inhibition of sealing end 113, has pressure when the slurry is transferred to the sealing end 113 It is extruded with the slurry of speed in sealing end and is squeezed out after biggish pressure and speed from the nozzle 120 with being formed.The sealing end 113 settings can increase the pressure and speed of slurry, or delivery pump can be reduced under same pressure and rate request Power.The discharge nozzle 100 can be circle, ellipse etc..

The discharging ring 200 include discharging ring body 210, the discharging ring body 210 be tubular hollow structure, it is described out Multiple discharge holes 220 are provided in material ring body 210.The discharge nozzle 100 setting 200 inside of discharging ring and with discharging Separately, the discharging ring 200 can rotate ring 200 around the discharge nozzle 100.By the discharge nozzle 100 and the discharging The setting of the interval of ring 200 keeps the rotation of discharging ring 200 more smooth, reduces resistance.

It is understood that the center or off-centered position of the discharging ring 200 is arranged in the discharge nozzle 100 It sets.Preferably, the discharge nozzle 100 is from the direction of nozzle 120 is equipped with close to the discharging ring body 210, that is to say, that described The axial line (not shown) of discharging ring 200 is not overlapped with the axial line 114 of the discharge nozzle 100, and the axis of the discharge nozzle 100 Heart line 114 compared to the discharging ring 200 axial line close to the nozzle 120.Can shorten the discharging ring 200 with it is described go out The distance of 100 phase of expects pipe cutting, so that the discharging ring 200 cuts the material with larger speed squeezed out from nozzle 120 Slurry.

It is understood that the tubular hollow structure refers to that intermediate is hollow tubular structure.Preferably, the discharging Ring body 210 can be, but not limited to as cylindrical hollow structure, polygon prism cylindrical structure.It is understood that the discharging ring 200 can refer to that the discharging ring 200 itself can be revolved around the axial line 114 of discharging ring around the discharge nozzle 100 rotation Turn, it may also be said to be 200 rotation of discharging ring.It is noted that not seeing in discharging ring body 210 in Fig. 1 Discharge hole 220, this is because the discharging ring body 210 is rotated to that discharge hole 220 is not presented in the sectional view of certain position, When the discharging ring body 210 rotates to another angle, discharge hole 200 can be presented carrying out sectional view parsing, out Discharge hole 220 in material ring body 210 can refer to shown in Fig. 2, Fig. 5 or Fig. 6.

When the intelligence, which floats grain discharging device 10, to work, slurry is transported in discharge nozzle 100, in discharging tube body It gathers in 110, and is squeezed out by logical nozzle 120 related to discharging tube body 110.During the work time, the discharging ring sheet Body 210 is ceaselessly rotated around the discharge nozzle 100, in the discharging ring body 210 that the slurry squeezed out from nozzle 120 is rotated again Discharge hole 220 cut off, drop is formd, wherein the direction and slurry that cut off are perpendicular from the direction that nozzle sprays.From nozzle 120 slurries squeezed out are by the discharge hole 220 in discharging ring 210, due to discharge hole 220 as discharging ring body 210 is not being stopped Rotation, slurry substantially cuts off by discharge hole 200 when passing through discharge hole 220, therefore forms drop.From discharge hole 200 Drop out forms particle under quick refrigeration.It is understood that the slurry can be also possible to other with fertilizer slurry Need to change the slurry of upper drop.The fertilizer slurry refer to by nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, middle trace element fertilizer, organic carbon fertilizer, One of microorganism fertilizer etc. or it is a variety of be mixed to form fertilizer slurry, can also be with wherein mixed mode can be level-one mixing It is second level mixing, three-level mixing etc., it is to be understood that the conditions such as sequence, temperature, pH value of fertilizer slurry mixing are unlimited, can It requires to be adjusted according to the characteristic of the material composition of fertilizer slurry and mixing.
