Description

Technical Field

[0001] The invention belongs to the technical field of agricultural monitoring, and in particular relates to an agricultural remote sensing detection device. Background Art

[0002] Agricultural remote sensing refers to a comprehensive technology that uses remote sensing technology to conduct agricultural resource surveys, analyze land use status, monitor agricultural pests and diseases, and estimate crop yields. Remote sensing satellites can quickly and accurately acquire ground-based information. Combined with other modern high-tech technologies such as geographic information systems and global positioning systems, remote sensing satellites can collect and analyze agricultural information in a timely, quantitative, and targeted manner. This highly objective and interference-free manner facilitates agricultural decision-making and enables the development of precision agriculture.

[0003] Agricultural remote sensing can use remote sensing technology to monitor crop planting area and crop growth information, quickly monitor and evaluate crop growth, compare and identify areas with abnormal growth, and analyze whether there are abnormal conditions such as stagnation in crop growth, making it easier for managers to discover and solve crop growth problems in a timely manner. It plays a very important role in crop growth monitoring.

[0004] At present, agricultural remote sensing detection equipment can only monitor the growth of crops through satellites or drones. When abnormal conditions are detected, staff can only go to the abnormal crop growth area to check and detect, sample and analyze the soil in the abnormal growth area, detect whether there is a lack of fertilizer or water, and then take corresponding measures based on the detection results. For agricultural sites with larger areas, staff need to spend more time to locate the area, navigate to the area, sample the soil and return for testing, which is not only time-consuming but also consumes a lot of manpower. Summary of the Invention

[0006] The technical solution of the present invention is: an agricultural remote sensing detection device, comprising a drone and a sampling mechanism and a remote sensing monitoring component installed below the drone, wherein the sampling mechanism comprises:

[0007] A first telescopic rod, the upper end of which is movably connected to the bottom of the drone and the lower end of which is provided with an inclined end surface;

[0008] The rotary mechanism includes a rotating shaft passing through the inclined end surface, a driven bevel gear provided at the inner end of the rotating shaft, a driving motor provided inside the telescopic rod, and a wheel provided at the outer end of the rotating shaft, wherein the rotating shaft of the driving motor is engaged with the driven bevel gear through a bevel gear to drive the wheel to rotate;

[0009] A plurality of sampling mechanisms are equidistantly arranged on the wheel disc, and the sampling mechanisms can all be rotated to be parallel to the telescopic rod.

[0010] Furthermore, the sampling mechanism includes:

[0022] Furthermore, the UAV includes a plurality of rotors arranged on the upper side of the UAV and a plurality of support legs arranged on the lower side of the UAV.

[0023] Furthermore, a stabilizing ring is connected to the lower ends of the plurality of support legs to prevent the drone from tipping over when landing on an uneven ground at a monitoring point.

[0024] Furthermore, the lower end of the stabilizing ring is evenly provided with serrations to prevent the drone from shifting during the sampling process, and never affects the sampling process.

[0025] Furthermore, the rotors are each provided with a protective net to prevent crops from getting entangled in the rotors and damaging the drone.

[0026] The working method of the present invention is as follows: in an agricultural remote sensing monitoring area, a monitoring point where no crops are planted is set in each acre of land. The UAV performs the agricultural remote sensing monitoring task as planned, monitors the growth of crops through the remote sensing monitoring component, and transmits the monitoring data back to the detection base station. The detection base station judges the growth of crops based on the monitoring data. If abnormalities such as hysteresis in the growth of crops in a certain area are detected, a sampling instruction is sent to the UAV. The UAV flies to the abnormal area and lands at the monitoring point. The driving motor drives the wheel to rotate, so that a sampling mechanism rotates to a vertical state. The first telescopic rod is extended under the action of hydraulic pressure, so that the sampling tube is inserted into the soil through the semi-cone at the front end.

The drone can continue to sample or fly to the next monitoring point for sampling. The sampling process is the same as above. The height of the temporary storage box is increased by one temporary storage tube each time compared with the previous time. When the sampling is completed or the drone is low on power, it returns. The staff only needs to test the soil samples in the temporary storage tube to know the cause of the abnormal soil condition in the area and formulate corresponding solutions.

A partition is provided in the sampling tube to separate the sampling tube into two parts, one part for sampling, and a cutting mechanism is provided in the other part to cut the soil entering the sampling tube to prevent the soil from falling. At the same time, a temporary storage mechanism is provided to temporarily store the soil in the sampling tube, facilitating multiple sampling by the drone.
