As a specific embodiment of the present invention, a liquid outlet 10 is formed at the bottom of the rotary pipe 63, and a one-way valve is installed at the liquid outlet 10;
through adopting above-mentioned technical scheme, after the higher mixed solution of concentration of upper portion gets into rotation pipe 63 in, the controller control check valve opens, and the higher mixed solution of concentration flows from the liquid outlet 10 of rotation pipe 63 bottom again, diffuses from bottom to top, forms the self-loopa in the mixing drum 61, and simultaneously accompanies the stirring of puddler 64, further promotes the misce bene of mixed solution.
As shown in fig. 1, as a specific embodiment of the present invention, a drain pipe 11 is fixedly connected to the bottom of the mixing tank 61, so as to facilitate transportation of the mixed liquor to the farmland through a pipeline.
Working principle:
when preparing the water-fertilizer mixed solution which meets the requirement of crop growth, firstly, a first motor 3 is started by people according to a controller, an output shaft of the first motor 3 rotates to drive a crushing cutter 21 to rotate, at the moment, a worker adds a water source and fertilizer with corresponding mass into a premixing unit 2 according to the required water-fertilizer ratio, the crushing cutter 21 crushes part of blocky or indissolvable fertilizer which enters the premixer 22, meanwhile, the water source enters a mixing barrel 61 from a water inlet pipe 24, the water source is primarily contacted and mixed with the fertilizer in the premixer 22, the premixing of the water source and the fertilizer is realized, and at the moment, the concentration of the water-fertilizer mixed solution in the premixer 22 is larger;
the fertilizer in the premixer 22 is washed and diluted from top to bottom by water flow, falls through the filter holes 26 under the crushing of the crushing knife 21, and then shunts the premix into the anion adjusting barrel 41 and the cation adjusting barrel 41 by pipelines, the required anion and cation ratio is determined according to the corresponding crop growth requirement, and the corresponding gear 46 tooth number is selected according to the anion and cation ratio, so that the gear 46 transmission ratio is the same as the anion and cation ratio;
after the fertilizer and the water source in the premixer 22 flow into the anion adjusting barrel 41 and the cation adjusting barrel 41 as much as possible, the second motor 5 is controlled by the controller to start, the output shaft of the second motor 5 rotates to drive the transmission shaft 45 to rotate, the transmission shaft 45 rotates to drive the transmission shaft 45 on the other side to rotate through the meshing of the gear 46, the transmission shaft 45 rotates to drive the threaded rod 43 to rotate, when the threaded rod 43 rotates, the piston 44 block is in threaded connection with the threaded rod 43, and the metal block in the piston 44 block is in sliding connection with the inner wall of the ion adjusting barrel 41 through the sliding groove, so that the movement of the piston 44 block is limited and can not rotate along the threaded rod 43, and only can slide up and down along the side wall of the ion adjusting barrel 41, at the moment, when the threaded rod 43 rotates, the piston 44 blocks in the two adjusting barrels move in the same direction;
when the threaded rod 43 rotates positively, the piston 44 moves downwards, gas and liquid in the ion regulating barrel 41 are extruded, the pressure in the ion regulating barrel 41 is increased, the number of teeth of the pinion 46 with fewer teeth is higher due to the fact that the number of teeth of the gear 46 on the transmission shaft 45 is different, the rotation speed of the rotation shaft fixedly installed with the pinion 46 is higher, the rotation speed of the threaded rod 43 is higher, the moving speed of the piston 44 on the threaded rod 43 with higher rotation speed is higher, the moving distance of the piston 44 below the pinion 46 is larger than the moving distance of the piston 44 below the large gear 46 under the condition that the moving time of the piston 44 in the ion regulating barrel 41 is the same, the pressure in the ion regulating barrel 41 with larger air pressure is larger than the pressure in the ion regulating barrel 41 with smaller air pressure, and therefore the speed of the ion in the ion regulating barrel 41 with larger air pressure for penetrating through the ion exchange membrane is larger than that in the ion regulating barrel 41 with smaller air pressure;
when ions penetrate through the ion exchange membrane 42 and enter the mixing barrel 61 through the three-way pipe, meanwhile, a worker starts according to the controller controlling the motor No. three 62, the output shaft of the motor No. three 62 rotates to drive the rotating pipe 63 to rotate, the rotating pipe 63 drives the stirring rod 64 to rotate, the mixed liquid is stirred, and then the mixed liquid is discharged through the liquid discharge pipe 11.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
