[0051] A soil information collection method for fertilization control, comprising:

[0052] S100, after the collection vehicle 8 moves to the designated position, the first driving member 11 and the first transmission gear 16 are used to control the rotating shaft 12, the center frame 13, the arc-shaped shell 14 and the drill bit 15 to rotate clockwise, and the longitudinal telescopic member 61 is used to control the lifting plate 62, the rotating shaft 12, the center frame 13, the arc-shaped shell 14 and the drill bit 15 to drill the soil until the three groups of arc-shaped shells 14 are completely located under the soil and stop. Since the L-shaped block 32 and the partition plate 43 block the arc-shaped shell 14 and rotate synchronously with the drill bit 15, the soil will not enter the arc-shaped shell 14;

[0053] S200, use the second driving member 211 to control the transmission tube 212, the first key bar 221 and the transmission rod 22 to rotate 360 ​​degrees or 720 degrees counterclockwise. In the initial state, the elastic force of the return spring 232 drives the end cover plate 223 to fit with the limit block 131, and the second key bar 222 is located in the first key groove 33. Therefore, the rotating transmission rod 22 drives the soil collection part 3 to rotate synchronously through the second key bar 222 and the first key groove 33. The rotating L-shaped block 32 uses the counterclockwise opening to send the soil into the first cavity of the arc-shaped shell 14, and the L-shaped block 32 drives the soil to move on the surface of the filter screen 141, and the soil with smaller particle size passes through the filter screen 141 and enters the lower cavity. The second cavity, the sample holding box 5 in the second cavity is used to collect soil with smaller particles, and weeds or large particles of soil are moved out of the arc-shaped shell 14 by the rotating L-shaped block 32. On the one hand, it can ensure the particle uniformity of the soil sample, which helps to improve the accuracy of soil detection, and on the other hand, it can automatically move the isolated weeds and large particles of soil back into the soil. The three groups of arc-shaped shells 14 with different heights can collect soil samples of different depths at the same time. The three groups of sample holding boxes 5 in each group of arc-shaped shells 14 can collect three groups of soil samples at the same depth, which not only improves the work efficiency of soil sample collection, but also improves the diversity and accuracy of sample collection;

[0054] S300, using the lifting unit 6 to control the drill bit 15 to rise and reset, and controlling the electromagnet 231 to be energized. Since the electromagnet 231 after being energized is magnetically attached to the magnetic ring 224, the transmission rod 22 can be controlled to move along its own axis, so that the second key bar 222 is located in the second key slot 44. The driving unit 21 is used to control the transmission rod 22 to rotate 180 degrees counterclockwise, so that the placement plate 42 and the sample holding box 5 are completely located outside the arc-shaped shell 14, so that the sample can be taken out and placed in the detection and setting out drawer 84 for detection. The display 83 is controlled to detect the soil sample in the detection and setting out drawer 84, and the soil sample to be detected or after the detection is completed is temporarily stored in the first storage bin 86 or the second storage bin 87 for storage;

[0055] S400, connect the liquid pump 7 to a water source, and the liquid pump 7 discharges the water source into the uppermost arc-shaped shell 14 through the drain pipe 71 and the elbow 18, so as to clean the residual soil in the arc-shaped shell 14, and the waste liquid after cleaning flows into the two arc-shaped shells 14 below through the conduit 19, so as to clean the arc-shaped shells 14 of the lower layer, so as to ensure the purity and accuracy of the soil sample collected next time.

[0056] To summarize, the structural design of the arc-shaped shell 14, the driving module 2, the soil collection part 3, the rotating part 4 and the sample holding box 5 cooperate with each other. On the one hand, it can prevent the soil from entering the arc-shaped shell 14 when the drill bit 15 drills into the soil. On the other hand, in the process of sending the soil into the arc-shaped shell 14 by the rotating L-shaped block 32, not only the soil with smaller particles is automatically passed through the filter 141 into the sample holding box 5 below, but also the weeds or large particles of soil are automatically moved out of the arc-shaped shell 14. In addition, the sample holding box 5 containing the soil sample can be automatically moved to the outside of the arc-shaped shell 14, which has the characteristics of uniform sample particles, high purity and convenient sampling.

7. The soil information collection device for fertilization control according to claim 6, characterized in that: The lifting part (6) comprises a longitudinal telescopic member (61) and a lifting plate (62), wherein the longitudinal telescopic member (61) is fixedly connected to the lifting plate (62), the first driving member (11) is fixedly connected to the lifting plate (62), and the rotating shaft (12) is rotatably connected to the surface of the lifting plate (62).

8. The soil information collection device for fertilization control according to claim 7, characterized in that: The collection vehicle (8) comprises a base (81), a frame (82), a control display (83), a detection and setting-out drawer (84), an electric control compartment (85), a first storage compartment (86), a second storage compartment (87) and a moving wheel group (88); the frame (82) and the moving wheel group (88) are respectively fixedly connected to the upper and lower sides of the base (81); the surface of the frame (82) is provided with a control display (83), a detection and setting-out drawer (84) and a first storage compartment (86); the surface of the base (81) is provided with a second storage compartment (87); the longitudinal telescopic member (61) is fixedly connected to the inner wall of the frame (82); the lifting plate (62) is in sliding contact with the inner wall of the frame (82); the side of the frame (82) away from the control display (83) is provided with an electric control compartment (85); and the liquid pump (7) is fixedly connected to the electric control compartment (85).

9. A soil information collection method for fertilization control, applied to a soil information collection device for fertilization control as claimed in any one of claims 1 to 8, characterized in that: include: S100, using the first driving member (11) and the lifting part (6) to control the drill bit (15) to rotate clockwise until the arc-shaped housing (14) is completely located below the soil and stops. Since the L-shaped block (32) and the partition plate (43) block the arc-shaped housing (14) and rotate synchronously with the drill bit (15), soil will not enter the arc-shaped housing (14); S200, using the driving unit (21) to control the transmission rod (22) to rotate 360 ​​degrees or 720 degrees counterclockwise. Since the second key bar (222) is located in the first key slot (33) in the initial state, the rotating transmission rod (22) drives the soil collection unit (3) to rotate synchronously through the second key bar (222) and the first key slot (33). Soil with smaller particle size passes through the filter screen (141) and enters the second cavity below. The sample holding box (5) in the second cavity is used to collect soil with smaller particle size. Weeds or large particles of soil are moved out of the outer side of the arc-shaped shell (14) by the rotating L-shaped block (32); S300, using the lifting part (6) to control the drill bit (15) to rise and reset, using the adjusting part (23) to control the transmission rod (22) to move along its own axis, so that the second key bar (222) is located in the second key groove (44), and using the driving part (21) to control the transmission rod (22) to rotate 180 degrees counterclockwise, so that the storage plate (42) and the sample holding box (5) are completely located outside the arc-shaped shell (14), so as to facilitate the removal of the sample for inspection.
