[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Embodiment 1

[0027] like Figure 1-Figure 3As shown, the present embodiment provides a liquid organic fertilizer precision application device suitable for field experiments, including a liquid fertilizer applicator and a conveying pipeline laid in the field. The liquid fertilizer applicator adopts existing equipment and is not described in detail here; the conveying pipeline includes a main pipeline 1, a liquid distribution pipeline 2 and a plurality of branch pipelines 3, and electromagnetic valves 5 are installed on the main pipeline 1 and the branch pipeline 3; a plurality of fertilizer outlet pipes 4 are connected to the branch pipeline 3, and the end of the fertilizer outlet pipe 4 is connected to a temporary storage tank 6, and the lower end of the temporary storage tank 6 is a liquid outlet tip for direct insertion into the soil; a cover plate is buckled on the top of the temporary storage tank 6, a through hole is opened in the middle of the cover plate, and a guide tube 7 is fixedly connected in the through hole; the lower part of the temporary storage tank 6 is a conical structure, and a blocking ball 9 is arranged at this position, and the guide There is a certain distance between the bottom of the tube 7 and the blocking ball 9 to facilitate the displacement of the blocking ball 9; one end of the connecting rope 11 is connected to the blocking ball 9, and the other end of the connecting rope 11 extends to the outside of the temporary storage tank 6 through the guide tube 7 and is connected to the limit plate 10; a threaded sleeve 12 and a threaded rod 13 for adjusting the height of the limit plate 10 are provided between the limit plate 10 and the cover plate, wherein the threaded rod 13 is fixed to the limit plate 10, and the threaded sleeve 12 is rotatably connected to the cover plate, and the length of the threaded rod 13 extending out of the threaded sleeve 12 is adjusted by rotating the threaded sleeve 12 to adjust the distance between the limit plate 10 and the cover plate, thereby adjusting the position of the blocking ball 9 through the connecting rope 11 to control the on and off of the bottom liquid outlet of the temporary storage tank 6. The structure for adjusting the distance between the cover plate and the limit plate 10 can also adopt other devices.

[0028] A liquid level switch is provided at the port of the fertilizer discharge pipe 4 located in the temporary storage tank 6. The liquid level switch includes a guide chute 14 fixed at the pipe mouth of the fertilizer discharge pipe 4. The bottom of the guide chute 14 is arc-shaped. A blocking plate 15 is limited and slidably provided in the guide chute 14. The arc-shaped structure of the guide chute 14 can prevent the blocking plate 15 from falling; a push rod 16 is fixedly connected to the lower end of the blocking plate 15, and the lower end of the push rod 16 extends out of the guide chute 14; at the same time, a floating block 8 is slidably sleeved on the outer wall of the guide pipe 7, and the floating block 8 can move up and down with the liquid level of the liquid organic fertilizer in the temporary storage tank 6. A baffle 19 is provided at the bottom of the guide pipe 7 to prevent the floating block 8 from falling. A lifting plate 17 is fixed on the outer wall of the floating block 8, and the lifting plate 17 is correspondingly arranged with the push rod 16 on the sealing plate 15.

[0029] The liquid organic fertilizer precision application device suitable for field trials provided by the present invention has the following working principles:

[0030] Initially, the sealing ball 9 in the temporary storage tank 6 is in a sealed state with respect to the bottom of the temporary storage tank 6. At this time, the liquid organic fertilizer flowing into the temporary storage tank 6 through the fertilizer outlet pipe 4 will be stored in the temporary storage tank 6. When the liquid level of the liquid organic fertilizer in the temporary storage tank 6 continues to rise, the floating block 8 and the lifting plate 17 will also continue to rise along the guide tube 7. When the lifting plate 17 contacts the push rod 16, as the liquid organic fertilizer continues to enter the temporary storage tank 6, the sealing plate 15 will rise along the guide chute 14 under the buoyancy of the floating block 8 and the push rod 16. At this time, , the flow rate of the liquid organic fertilizer flowing into the temporary storage tank 6 from the fertilizer outlet pipe 4 should also be reduced until the blocking plate 15 completely blocks the fertilizer outlet pipe 4. At this time, the liquid organic fertilizer cannot enter the temporary storage tank 6. In the process of the liquid organic fertilizer entering the temporary storage tank 6, since the liquid organic fertilizer will flood the bottom of the guide pipe 7, in order to prevent the pressure of the liquid organic fertilizer in the temporary storage tank 6 from increasing and being discharged through the guide pipe 7, an exhaust port 18 is opened at the top of the guide pipe 7 to keep the pressure in the temporary storage tank 6 from increasing with the entry of the liquid organic fertilizer.

[0031] By setting the temporary storage tank 6 and the liquid level switch, the amount of liquid organic fertilizer entering the temporary storage tank 6 in the branch pipeline 3 is relatively consistent. When the liquid organic fertilizer in the temporary storage tank 6 reaches a certain amount, the liquid organic fertilizer cannot enter the temporary storage tank 6, thereby controlling the amount of liquid organic fertilizer in each temporary storage tank 6 to be relatively consistent. Through the degree of the pressure valve set on the branch pipeline 3, it can be judged whether the liquid organic fertilizer in each temporary storage tank 6 is full. When the liquid organic fertilizer in each temporary storage tank 6 is full, the solenoid valve 5 on the branch pipeline 3 is closed, and the sealing ball 9 is lifted by the connecting rope 11 to keep the bottom outlet of the temporary storage tank 6 unobstructed, and the crops can be accurately fertilized at this time.

[0033] like Figure 4 As shown, this embodiment provides a liquid organic fertilizer precision application device suitable for field trials. On the basis of the first embodiment, the liquid organic fertilizer precision application device suitable for field trials of this embodiment also has the following characteristics:

[0034] In order to conveniently control the storage amount of liquid organic fertilizer in the temporary storage tank 6, a connection port 20 is provided on the side wall of the temporary storage tank 6. The connection port 20 is located below the push rod 16 when the fertilizer outlet pipe 4 is in an unblocked state. Liquid storage pipes 21 of different capacities are threadedly connected through the connection port 20 to expand the temporary storage tank 6. When expansion is not required, the connection port 20 can be blocked by a plugging wire.
