A second spring 11 is fixedly connected between the second blocking block 10 and the second through-groove disk, and the second spring 11 is sleeved on the outer surface of the second connecting rod. Specifically, the first motor 14 is turned on, and the first motor 14 drives the disc 15 to rotate.

The other end of the first adjusting screw 36 is rotatably connected to a connecting block 37, and one end of the telescopic rod 16 away from the piston rod 13 is rotatably connected to the connecting block 37. Specifically, by rotating the first adjusting screw 36, the position of the connecting block 37 is adjusted, thereby adjusting the position of one end of the telescopic rod 16, and then adjusting the proportioning amount when the disc 15 rotates.

When batching, the first motor 14 is turned on, and the first motor 14 drives the disc 15 to rotate. As the disc 15 rotates, the telescopic rod 16 is pulled, so that the telescopic rod 16 rotates between the piston rod 13 and the connecting block 37. As the disc 15 rotates, the piston rod 13 is pulled to make the piston disc 12 move inside the piston cylinder 6, and the pressure inside the piston cylinder 6 decreases. Under the action of air pressure, the first block 8 is pulled downward to compress the first spring 9, so that the liquid enters the interior of the piston cylinder 6 through the gap between the first block 8 and the discharge funnel 4. When the disc 15 rotates to push the piston rod 13, the air pressure inside the piston cylinder 6 increases, and the air pressure squeezes the second block 10 to stretch the second spring 11, and the liquid fertilizer enters the mixing cylinder 2 through the gap between the second block 10 and the discharge pipe 7, and the first adjusting screw 36 is rotated to adjust the connecting block 37. When the quantitative groove 22 corresponds to the discharge end at the bottom of the fixed storage barrel, the solid fertilizer enters the quantitative groove 22, and the second motor 20 is turned on.

The surfaces are movably meshed. Specifically, the third motor 24 is turned on, and the third motor 24 drives the rotating shaft 23 to rotate, and drives the first bevel gear 26 and the stirring blades 28 thereon to rotate. The first bevel gear 26 on the rotating shaft 23 rotates to drive the second bevel gear 27 to rotate, and the second bevel gear 27 drives the first bevel gear 26 on the sleeve shaft 25 to rotate, thereby causing the sleeve shaft 25 to rotate. The rotation directions of the sleeve shaft 25 and the rotating shaft 23 are opposite, so that the rotating shaft 23 and the stirring blades 28 on the sleeve shaft 25 rotate in opposite directions, thereby stirring the fertilizer in multiple directions, thereby improving the mixing effect of the fertilizer.

[0030] In this embodiment, a spiral blade 29 is fixedly sleeved on the outer surface of the sleeve shaft 25. Specifically, when the sleeve shaft 25 rotates, the spiral blade 29 is driven to rotate, so that the spiral blade 29 flips the fertilizer at the bottom upward to prevent the fertilizer from accumulating at the bottom.

Specifically, fertilizer is extracted from the mixing barrel 2 by the pumping pump 30, and the fertilizer is discharged into the two-way pipe 31, enters the transverse pipe 33 through the telescopic hose 32, and is sprayed out through the nozzle.

[0034] In this embodiment, two vertical plates are fixedly connected to the top outer surface of the base plate 1, and a forward and reverse screw rod 34 is rotatably connected between the two vertical plates. The outer surface of the forward and reverse screw rod 34 is threadedly connected to two L-shaped plates 35, and two horizontal tubes 33 are respectively fixedly connected to the top outer surfaces of the two L-shaped plates 35. Specifically, the forward and reverse screw rod 34 is rotated, and the rotation of the forward and reverse screw rod 34 drives the L-shaped plate 35 to move, thereby adjusting the distance between the two horizontal tubes 33 on the left and right sides, so that the spacing between the left and right nozzles can be adjusted as needed, which is convenient for the nozzles to spray crops at different spacings.

[0035] In the specific implementation process, the fertilizer is extracted from the mixing barrel 2 by the extraction pump 30, and the fertilizer is discharged into the two-way pipe 31, and enters the horizontal pipe 33 through the telescopic hose 32, and is sprayed out through the nozzle. By rotating the forward and reverse screw rods 34, the forward and reverse screw rods 34 rotate to drive the L-shaped plate 35 to move, and the distance between the two horizontal pipes 33 on the left and right sides is adjusted, so that the distance between the nozzles on the left and right sides can be adjusted as needed, so that the nozzles can spray crops at different distances.

[0036] Working principle: When the present invention is in use, the liquid fertilizer and the solid fertilizer are stored in the liquid storage cylinder 3 and the solid storage cylinder 17 respectively. When batching, the first motor 14 is turned on, and the first motor 14 drives the disc 15 to rotate. As the disc 15 rotates, the telescopic rod 16 is pulled, so that the telescopic rod 16 rotates between the piston rod 13 and the connecting block 37. As the disc 15 rotates, the piston rod 13 is pulled to make the piston disc 12 move inside the piston cylinder 6, and the pressure inside the piston cylinder 6 decreases. Under the action of air pressure, the first block 8 is pulled downward to compress the first spring 9, so that the liquid enters the interior of the piston cylinder 6 through the gap between the first block 8 and the discharge funnel 4. When the disc 15 rotates to push the piston rod 13, the air pressure inside the piston cylinder 6 increases, and the air pressure squeezes the second block 10 to stretch the second spring 11, and the liquid fertilizer enters the mixing cylinder 2 through the gap between the second block 10 and the discharge pipe 7, and the connecting block 3 is adjusted by rotating the first adjusting screw 36. 7, thereby adjusting the position of one end of the telescopic rod 16, and then adjusting the proportion of the disc 15 when it rotates; when the quantitative groove 22 corresponds to the discharge end at the bottom of the fixed storage barrel, the solid fertilizer enters the quantitative groove 22, and the second motor 20 is turned on. The second motor 20 drives the quantitative cylinder 21 to rotate, and makes the quantitative groove 22 rotate. When the quantitative groove 22 corresponds to the discharge cylinder 19, the solid fertilizer enters the mixing cylinder 2 through the discharge cylinder 19. When the amount in the quantitative groove 22 needs to be adjusted, the knob is turned, and the knob drives the adjusting shaft to rotate, so that the third bevel gear 38 thereon rotates, and the third bevel gear 38 drives the fourth bevel gear 39 to rotate, so that the second adjusting screw 40 rotates, and the second adjusting screw 40 drives the threaded block 41 to move, and adjusts the position of the limit block in the quantitative groove 22, so as to adjust the amount of solid fertilizer in the quantitative groove 22, so that the liquid fertilizer and the solid fertilizer can be quantified more accurately, the accuracy of the fertilizer ratio is improved, and the fertilization effect of the fertilizer is improved.

[0037] After the fertilizer enters the mixing barrel 2, the third motor 24 is turned on. The third motor 24 drives the rotating shaft 23 to rotate, and drives the first bevel gear 26 and the stirring blades 28 thereon to rotate. The rotation of the first bevel gear 26 on the rotating shaft 23 drives the second bevel gear 27 to rotate. The second bevel gear 27 drives the first bevel gear 26 on the sleeve shaft 25 to rotate, thereby causing the sleeve shaft 25 to rotate. The rotation directions of the sleeve shaft 25 and the rotating shaft 23 are opposite, so that the rotating shaft 23 and the stirring blades 28 on the sleeve shaft 25 rotate in opposite directions, thereby stirring the fertilizer in multiple directions, thereby improving the mixing effect of the fertilizer.

[0038] The fertilizer is extracted from the mixing barrel 2 by the extraction pump 30, and is discharged into the double-way pipe 31, enters the horizontal pipe 33 through the telescopic hose 32, and is sprayed out through the nozzle. By rotating the forward and reverse screw rods 34, the forward and reverse screw rods 34 drive the L-shaped plate 35 to move, and the distance between the two horizontal pipes 33 on the left and right sides is adjusted, so that the distance between the nozzles on the left and right sides can be adjusted according to needs, so that the nozzles can spray crops at different distances.
