[0030] In this embodiment, the uniform stirring mechanism includes a stirring tank 2, a stirring motor 3, a stirring shaft 4 and a stirring blade 5. When in use, the stirring motor 3 on the support frame 24 on the stirring tank 2 is driven to drive the stirring shaft 4, so that the stirring blade 5 on the stirring shaft 4 rotates. During this process, the other end of the stirring shaft 4 rotates in the fixed block 21 inside the stirring tank 2, and under the stirring of the stirring blade 5, the materials inside the stirring tank 2 are mixed, and finally the solid and liquid fertilizers are discharged from the discharge pipe 22.

[0031] In this embodiment, the grinding mechanism includes a feed hopper 6, a grinding box 7, a grinding assembly and a grinding motor 8. The grinding assembly includes a grinding roller 16 and a matching gear 17. When in use, after the solid fertilizer enters the feed hopper 6, it enters the grinding box 7 under the influence of gravity. At this time, the grinding motor 8 is driven to mobilize the grinding roller 16, and the matching gear fixedly installed at one end of the grinding roller 16 rotates under the drive of the grinding roller 16, so that the two matching gears 17 are engaged with each other to drive the other grinding roller 16. In this process, the grinding blocks 18 on the two grinding rollers 16 squeeze the solid fertilizer against each other to grind the solid fertilizer. In addition, the solid fertilizer that has not been ground in the gap of the grinding box 7 falls onto the filter drawer 19, and the solid fertilizer ground into powder enters the mixing tank 2 along the filter screen 20 of the filter drawer 19. The remaining fixed fertilizer is taken out and put into the feed hopper 6 again for secondary grinding.

When the liquid fertilizer enters the quantitative box 12, due to continuous conveyance, under the action of the liquid, the measuring float 13 automatically floats up, and the scale on the measuring float 13 will also increase with the increase in the amount of liquid fertilizer. The liquid fertilizer slowly leaks out and keeps it flush with the top of the metering box 12. When it is determined that there is enough liquid fertilizer, the water pump 10 is stopped. During this process, the control valve 15 is closed. When the liquid fertilizer is quantitative, the control valve 15 is opened, and the liquid fertilizer stored in the metering box 12 will pass through the control valve 15 along the second infusion pipe 14, and then enter the feed pipe 23, and finally enter the mixing tank 2. Before the solid fertilizer and liquid fertilizer enter the mixing tank 2, since the control valve 15 is detachable, after the control valve 15 is removed, water is input into the feed pipe 23 and enters the mixing tank 2, and is mixed and diluted with the solid and liquid fertilizers to ensure the concentration.

In this process, the grinding blocks 18 on the two grinding rollers 16 squeeze the solid fertilizer against each other to grind the solid fertilizer. In addition, the solid fertilizer that has not been ground in the gap of the grinding box 7 falls into the filter The solid fertilizer ground into powder enters the mixing tank 2 along the filter screen 20 of the filter drawer 19, and the remaining fixed fertilizer is taken out and put into the feed hopper 6 for secondary grinding. At the same time, the water pump 10 is driven to extract the liquid fertilizer in the liquid storage tank 9 into the first infusion pipe 11, and then enters the quantitative tank 12 through the first infusion pipe 11. When the liquid fertilizer enters the quantitative tank 12, due to the continuous transportation, under the action of the liquid, the measuring float 13 automatically floats up, and the scale on the measuring float 13 will also As the amount of liquid fertilizer increases, it slowly leaks out and remains flush with the top of the quantitative box 12. When it is determined that the amount of liquid fertilizer is sufficient, the water pump 10 is stopped. During this process, the control valve 15 is closed. When the liquid fertilizer is quantitative, the control valve 15 is opened, and the liquid fertilizer stored in the quantitative box 12 passes through the control valve 15 along the second infusion pipe 14, then enters the feed pipe 23, and finally enters the mixing tank 2. Before the solid fertilizer and the liquid fertilizer enter the mixing tank 2, since the control valve 15 is detachable, after the control valve 15 is removed, Water is input into the feed pipe 23 and enters the stirring tank 2, where it is mixed and diluted with the solid and liquid fertilizers to ensure concentration. When the liquid fertilizer and the powdered solid fertilizer all enter the stirring tank 2, the stirring motor 3 on the support frame 24 on the stirring tank 2 is driven to drive the stirring shaft 4, so that the stirring blades 5 on the stirring shaft 4 rotate.
