[0025] A U-shaped baffle 3 is fixedly connected to the top of the cover plate 101. An air pump 2 is installed on the top of the cover plate 101. A pneumatic rotary agitator-type air supply switching component is installed on the top of the cover plate 101 for switching air supply between the pesticide storage area and the fertilizer storage area. The pneumatic rotary agitator-type air supply switching component is used to agitate the pesticide and fertilizer when the air pump 2 is started to prevent them from settling and affecting their use. It is also used to switch the air supply between the pesticide storage area and the fertilizer storage area for spraying or fertilizing, thereby achieving air injection and pressurization inside the pesticide storage area or the fertilizer storage area.

[0026] The top of the cover plate 101 is fitted with a spraying assembly that communicates with the interior of the pesticide storage area. The top of the cover plate 101 and the top of the partition plate 102 are fitted with the same low-point fertilizer spraying assembly that communicates with the water and fertilizer storage area. The spraying assembly is used to spray pesticides on the planted sorghum from top to outside when the pesticide is squeezed by the gas supply to the pesticide storage area. The low-point fertilizer spraying assembly is used to spray fertilizer on the lower part of the planted sorghum from the lower left side when the water and fertilizer are squeezed by the gas supply to the water and fertilizer storage area.

[0027] Specifically, the pneumatic rotary agitation switching air supply assembly includes a fixing sleeve 201 fixedly installed on the top of the cover plate 101. The top of the fixing sleeve 201 is connected to a fixing box 207 located inside the U-shaped baffle 3. Solenoid valves 205 are fixedly connected to both sides of the bottom of the fixing box 207. The bottom ends of both solenoid valves 205 extend into the liquid storage area. The bottom end of the solenoid valve 205 on the left side is connected to an air guide pipe 206, the bottom end of which extends into the water and fertilizer storage area. A transverse partition 102 is fixedly fitted onto the outer surface of the air guide pipe 206. The top of the cover plate 101 and the top of the transverse partition 102 are sealed and rotatably fitted with the same... A rotating shaft 202, wherein the top of the cover plate 101 and the top of the transverse partition 102 are both provided with circular through holes, and two sealed bearings are fixedly fitted inside the circular through holes. The inner ring of the sealed bearings is fixedly fitted to the outer side of the rotating shaft 202, so as to achieve the effect of sealing the rotating shaft 202 for rotation. Two stirring rods 204 are fixedly connected to the outer side of the rotating shaft 202 in both the water and fertilizer storage area and the medicine storage area. Multiple impeller blades 203 located in the fixed sleeve 201 are fixedly connected in a ring at equal intervals on the top of the outer side of the rotating shaft 202. The air outlet of the air pump 2 is connected and fixed to the left side of the fixed sleeve 201, and the air outlet of the air pump 2 is horizontally aligned with the front impeller blades 203.

[0028] The fixed sleeve 201, fixed box 207, solenoid valve 205, air guide pipe 206, rotating shaft 202, stirring rod 204, and impeller blade 203 work together. When the air pump 2 starts and blows air into the fixed box 207, the gas first blows to the left side of the front impeller blade 203 and drives it to rotate. The rotation of the impeller blade 203 drives the rotating shaft 202 to rotate, and the rotating shaft 202 drives the four stirring rods 204 to rotate, stirring the medicine and fertilizer solution and preventing it from settling and affecting its use. The gas supply to the fixed box 207 is as follows: When the gas is in the fixed sleeve 201, it continues to enter the fixed box 207. When the right solenoid valve 205 is opened, the gas is supplied to the pesticide storage area through the right solenoid valve 205. When the left solenoid valve 205 is opened and the right solenoid valve 205 is closed, the gas is supplied to the water and fertilizer storage area through the left solenoid valve 205 and the air guide pipe 206 in sequence. By opening and closing the corresponding solenoid valve 205, the gas supply can be switched between the pesticide storage area and the water and fertilizer storage area for spraying or fertilizing.

[0029] Furthermore, the spraying assembly includes an L-shaped tube 4 embedded and fixed to the top of the cover plate 101. The top of the cover plate 101 has a first mounting hole that is fixedly connected to the outside of the L-shaped tube 4. The bottom end of the L-shaped tube 4 extends to the lower inner part of the pesticide storage area. The left end of the L-shaped tube 4 is connected and fixed to a first horizontal tube 401 with both the front and rear ends being sealed. The left side of the first horizontal tube 401 is connected and fixed to multiple spray heads 402. The L-shaped tube 4, the first horizontal tube 401 and the spray heads 402 work together. When gas is supplied into the pesticide storage area, causing the internal pressure to increase, the pesticide is pushed out through the L-shaped tube 4 into the first horizontal tube 401, and then sprayed to the left by the multiple spray heads 402 to spray the planted sorghum.

[0030] Furthermore, the low-point fertilization assembly includes a U-shaped tube 5 embedded and fixed to the top of the cover plate 101 and the top of the partition plate 102. The top of the cover plate 101 and the top of the partition plate 102 are both provided with a second embedding hole that is fixedly connected to the outside of the U-shaped tube 5. The bottom right end of the U-shaped tube 5 extends to the lower inner part of the water and fertilizer storage area. The bottom left end of the U-shaped tube 5 is connected to a second horizontal tube 501 with a sealing structure at both ends. The second horizontal tube 501 is fixedly connected to the bottom left side of the liquid storage tank 1. The bottom of the second horizontal tube 501 is connected to a plurality of fertilizer outlet tubes 502 that are all inclined to the lower left. The U-shaped tube 5, the second horizontal tube 501 and the fertilizer outlet tubes 502 work together. When gas is supplied into the water and fertilizer storage area, causing the internal pressure to increase, the water and fertilizer are discharged through the U-shaped tube 5 into the second horizontal tube 501 under the pressure of the gas. Then, the fertilizer is sprayed to the left through the plurality of fertilizer outlet tubes 502 to perform fertilization work on the lower part of the planted sorghum.

[0031] Furthermore, a battery and a control panel 301 are fixedly installed on the right side of the U-shaped baffle 3. The air pump 2 and the two solenoid valves 205 are electrically connected to the control panel 301. The air pump 2, the two solenoid valves 205 and the control panel 301 are all electrically connected to the battery. The control panel 301 integrates switches for controlling the opening and closing of the air pump 2, the left solenoid valve 205 and the right solenoid valve 205 respectively, so that they can be moved out for personnel to perform opening and closing control operations on the three.

[0032] The usage method of this embodiment is as follows: When using the automatic spraying and fertilizing machine for sorghum planting, push the device to the location of the planted sorghum. When spraying is required, turn on the air pump 2 and the solenoid valve 205 on the right side. The air pump 2 starts to blow air into the fixed box 207. The gas first blows to the left side of the front impeller blade 203 and drives it to rotate. When the impeller blade 203 rotates, it drives the rotating shaft 202 to rotate. The rotating shaft 202 drives the four stirring rods 204 to rotate, stirring the pesticide and fertilizer to prevent them from settling and affecting use. When the gas is supplied into the fixed sleeve 201, the gas continues to... The solution continues to enter the fixed box 207, and is then supplied to the medicine storage area through the solenoid valve 205 opened on the right. When the internal pressure of the medicine storage area increases due to the gas supply, the medicine is discharged through the L-shaped pipe 4 into the first horizontal pipe 401 under the pressure of the gas. Then, it is sprayed to the left through multiple spray heads 402 to spray the planted sorghum, achieving the effect of automatically spraying the planted sorghum from the top. It can also automatically stir the medicine or fertilizer during spraying to prevent sedimentation, and does not require a separate rotary drive device. It has a good energy-saving effect while preventing sedimentation.

[0033] When fertilization is needed, the right solenoid valve 205 is closed and the left solenoid valve 205 is opened. At this time, the gas supplied into the fixed box 207 is converted into gas supplied into the water and fertilizer storage area through the left solenoid valve 205 and the air guide pipe 206. When the gas is supplied into the water and fertilizer storage area, the internal pressure increases. Under the pressure of the gas, the water and fertilizer are discharged through the U-shaped pipe 5 into the second horizontal pipe 501, and then sprayed to the left through multiple fertilizer outlet pipes 502 to perform fertilization work on the lower part of the planted sorghum. This allows for easy switching to the lower part fertilization state, which facilitates the integrated application of spraying and fertilization. There is no need to carry two separate devices, which improves the convenience of use. Moreover, by using the gas supply pressurization for switching and delivery, the pesticide and fertilizer will not pass through the same channel, avoiding cross-contamination of their residues and improving the stability of use.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
