[0002] The plant root system is the basis of plant growth and survival and plays multiple important functions. It is the main channel for plants to obtain water and mineral nutrients. The absorption function of the root system directly affects the nutritional status and growth and development of the plant. In particular, under different soil types and environmental conditions, the differences in the structure and function of the root system will significantly affect the effective utilization of nutrients. By studying the absorption mechanism of the root system, the interaction of rhizosphere microorganisms, and the relationship between the root system and the soil environment, scientists can optimize fertilizer use, increase crop yields, improve soil health, and achieve more sustainable agricultural production.

[0059] In this embodiment, a power supply 10 and a controller 9 are mounted on the second substrate 2 ; the controller 9 is provided with a first switch 31 and a second switch 32 .

[0060] Specifically, the first switch 31 is used to control the power-on and power-off status of the entire root drill and the controller; the second switch 32 is used to control the start-up and shutdown status of the automatic running program in the root drill controller.

[0061] The working process of the electric-driven automatic root drill provided in this embodiment is as follows:

[0062] Start the power supply and controller:

[0063] The user turns on the first switch 31, the whole power supply is powered on, and the controller 9 enters the power-on state. The controller 9 automatically loads the preset full-automatic program at this time, and the user can perform subsequent steps without manual operation.

[0064] Automatically set drill depth:

[0065] The controller 9 automatically sets the drilling depth of the root drill according to the built-in program. The user only needs to select appropriate parameters in the controller interface, and the remaining operations are completely controlled by the program. After completing the setting of the drilling depth, the user presses the second switch 32 to start the automatic operation of the root drill, and the root drill automatically starts drilling. The controller 9 will send a signal to the first motor 8 to drive the shaft to rotate forward, automatically drive the threaded rod 14 and the sampling container 15 to move downward along the set depth direction, and start drilling the root soil sample.

[0066] During the drilling process, the controller 9 will monitor the depth of the sampling container 15 in real time. When the sampling container 15 reaches the preset drilling depth, the controller 9 automatically switches the command, and the output shaft of the first worm gear reducer 7 rotates in the opposite direction, driving the threaded rod 14 and the sampling container 15 to automatically move upward, thus ending the drilling operation.

[0067] Inclined sampling drill tube:

[0068] When the sampling container 15 rises to a preset height above the ground, the controller 9 automatically stops the operation of the first motor 8. At this time, the controller 9 switches to the second motor 12, which drives the output shaft of the second worm gear reducer 11 to rotate forward, driving the threaded rod 14 and the sampling container 15 to tilt at a set angle, pointing to the direction of the root soil sample placement slot 20.

[0069] When the sampling container 15 reaches a predetermined tilt angle and is precisely aligned with the root soil sample placement slot 20, the controller 9 automatically stops the operation of the second worm gear reducer 11 and switches to the third engine 25 for starting. The third engine 25 drives the crankshaft connecting rod 27 to rotate through the transmission device 26, driving the push rod 16 to move up and down, automatically pushing out the root soil sample 33 in the sampling container 15 completely and placing it in the root soil sample placement slot 20.

[0070] Complete sample placement and repositioning:

[0071] When the root soil sample 33 is completely moved into the root soil sample placement groove 20, the controller 9 will automatically stop the operation of the third engine 25, and the push rod 16 will be reset to the initial position.

[0072] At the same time, the output shaft of the second worm gear reducer 11 is reversed, driving the threaded rod 14 and the sampling container 15 to return to the vertical direction, completing the entire sampling process.

[0073] After the root soil sample 33 is placed, the system will automatically enter the standby mode, and all electric components will stop working according to the program settings and wait for the next operation.

[0074] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
