Two supporting columns 12 are fixed at the bottom of the side, and a pumping cylinder 13 is fixed at the top of the supporting column 12. Two pistons 11 are respectively located inside the two pumping cylinders 13, and the pistons 11 are slidably matched with the inner wall of the pumping cylinder 13. The bottom of the pumping cylinder 13 is fixedly connected with a drainage tube 14 and an infusion tube 15. The drainage tube 14 is provided with a first one-way valve, so that the solution in the drainage tube 14 can only flow into the interior of the pumping cylinder 13 in one direction. The outside of the transmission rod 6 is fixedly sleeved with a fixed plate 16, and a plurality of stirring rods 17 are fixed at the bottom of the fixed plate 16. A driving motor 18 is provided on the top of the mixing barrel 3, and the transmission rod 6 is driven by the driving motor 18. An air blowing component is provided on the outside of the mixing barrel 3, and the air blowing component is used to agitate the solution in the discharge pipe 4;

[0024] By using a single drive motor 18 as a power source, the stirring rod 17 and the reciprocating screw 7 can be driven to rotate at the same time, so that the stirring rod 17 can stir the mixed fertilizer liquid in the mixing barrel 3 horizontally while the reciprocating screw 7 pulls the two pistons 11 to move back and forth in the longitudinal direction. The piston 11 cooperates with the pumping cylinder 13 to suck the mixed liquid at the bottom of the mixing barrel 3 along the inlet tube 14, and the mixed liquid is sprayed out along the infusion tube 15, collides with and mixes with the mixed liquid at the top of the mixing barrel 3, so that the fertilizer mixing efficiency is higher.

[0025] The top of the injection tube 5 is threadedly connected with a cap 19 , and the cap 19 can be used to seal the injection tube 5 to prevent foreign impurities from entering the interior of the mixing barrel 3 along the injection tube 5 .

[0026] The transmission rod 6 is externally fixedly sleeved with a support plate 20, and a filter layer 21 is arranged above the support plate 20. The filter layer 21 is made of multiple layers of filter screens, and the liquid outlet of the infusion tube 15 is located above the filter layer 21. The filter layer 21 is located above the carrier plate 9;

[0027] The filter layer 21 arranged above the support plate 20 is used to receive the solution discharged from the infusion tube 15. The filter layer 21 is made of multiple layers of filter screens stacked together to form holes to receive the solution. The filter layer 21 rotates with the transmission rod 6, and the solution received inside will be thrown out in a centrifugal manner, and the solution will be scattered more dispersedly, so as to better mix with the solution at the top of the mixing barrel 3.

[0028] The heating assembly includes a heating box 22, which is fixedly installed between the cushion block 2 and the mixing barrel 3. Two fixed blocks 23 are fixed inside the heating box 22, and a plurality of heating rods 24 are arranged between the two fixed blocks 23.

An air inlet of the air pump 26 is fixedly connected to the mixing barrel 3 with an air duct 28. An air supply pipe 27 is fixedly connected between the air outlet of the air pump 26 and the drain pipe 4. A second one-way valve is arranged on the air supply pipe 27, so that the air in the air supply pipe 27 can only flow into the interior of the drain pipe 4 in one direction.

[0031] With the help of the air pump 26, the air in the mixing barrel 3 can be driven to circulate. During the circulation process, the air can pass through the drain pipe 4, thereby driving the solution in the drain pipe 4 to tumble, so that the solution in the drain pipe 4 can participate in the mixing and stirring process to promote the comprehensive mixing of the fertilizer in the mixing barrel 3.

[0032] Working principle of this utility model:

[0033] Remove the cap 19, and add fertilizer and water into the mixing barrel 3 along the injection pipe 5. After the addition is completed, use the cap 19 to close the injection pipe 5 again, and start the drive motor 18 to drive the transmission rod 6 and the reciprocating screw 7 to rotate. The transmission rod 6 drives multiple stirring rods 17 to stir the mixed liquid in the mixing barrel 3 horizontally. The heating rod 24 is started to heat the bottom of the mixing barrel 3. With the help of the heat conductive sheet, the dissolution efficiency of the fertilizer in the mixing barrel 3 can be accelerated, so that the fertilizer mixing speed is faster. At the same time, the reciprocating screw 7 pulls the two pistons 11 to move back and forth in the longitudinal direction. The pistons 11 cooperate with the pumping cylinder 13 to absorb the solution at the bottom of the mixing barrel 3 along the liquid inlet pipe 14. After that, the piston 11 moves downward to discharge the solution absorbed in the pumping cylinder 13 along the infusion pipe 15. The solution falls on the filter layer 21 and will be immersed in the inside of the filter layer 21. The filter layer 21 can throw out the solution during the rotation process, so that the upper and lower layers of the solution in the mixing barrel 3 are accelerated. Mixing;

[0034] In order to avoid uneven mixing of the solution in the discharge pipe 4, the air pump 26 can be enabled to operate, so that the air pump 26 introduces air into the mixing barrel 3 along the air inlet pipe 28, and then discharges it into the discharge pipe 4 along the air supply pipe 27. In the process of the air in the mixing barrel 3 circulating under the traction of the air pump 26, the solution in the discharge pipe 4 can be driven to participate in the mixing and stirring process, so that the fertilizer solution inside the mixing barrel 3 is mixed more evenly. After the fertilizer solution is evenly mixed, the two-way valve on the discharge pipe 4 can be opened to take out the liquid fertilizer in the mixing barrel 3 for use.
