Description

Technical Field

[0001] The present invention relates to the technical field of crop planting, and in particular to a crop growth monitoring device based on an unmanned aerial vehicle. Background Art

[0002] During the planting process, it is necessary to monitor the growth of crops. By monitoring the growth of crops, agricultural workers can promptly discover whether the crops are lacking in nutrition or suffering from pests and diseases, thereby improving the yield and product quality of crops. Traditional crop growth monitoring mostly relies on agricultural workers to personally enter the fields for investigation. This monitoring method is not only inefficient, but also time-consuming and labor-intensive.

[0003] The existing application number is CN201910041168X, and the publication date is 2019-06-14. A patent document discloses a drone-based crop monitoring system and method, including a drone and a sensor. A cargo box is provided below the drone, and a controller is provided inside the cargo box. A hydraulic pump is provided at the lower left of the controller, and a hydraulic rod is connected to the right side of the hydraulic pump. A vertical pole is provided on the right side of the hydraulic rod, and a side groove is provided on the outer surface of the vertical pole. A rotating motor is provided on the right side of the vertical pole, and a rotating roller is connected to the right side of the rotating motor. A winding device is provided on the right side of the rotating roller. A base is installed below the sensor, and an extraction tube is provided on the left side of the base. A spring is installed on the inner surface of the extraction tube, and a cross plate is connected below the spring. The main feature of the drone crop monitoring system is that the drone is used to monitor crops back and forth, which saves manpower, and the monitoring equipment can be transported to areas that are difficult for humans to reach, greatly improving work efficiency.

[0004] Although the technical solution adopted in this application solves the problem of low efficiency in crop growth monitoring mentioned above, during the application process, the fan blades of the drone are close to the crops. When the drone shoots the crops, the branches and leaves of the crops will fall down with the rotating blades of the drone. In this process, not only will the planted crops be damaged, but as the crops fall down, it will also be difficult for the growers to observe the growth of the crops. For this reason, we propose a crop growth monitoring device based on drones. Summary of the invention

[0005] In order to solve the technical problem that the existing monitoring devices have poor working performance, the present invention provides a crop growth monitoring device based on a drone.

[0009] As a further improvement of the above scheme, the pushing block is a circular block, which cooperates with the surveillance camera and is made of a flexible material. The pushing block made of flexible material can avoid hard collision when the displaced surveillance camera contacts the pushing block, thereby causing damage to the surveillance camera.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] Embodiment 1:

[0031] Combination Figure 1 , Figure 2 and Figure 3 A crop growth monitoring device based on a drone of this embodiment includes a drone 1 and a mounting plate 2 arranged under the drone 1, a loading plate 4 is provided on the side of the mounting plate 2 away from the drone 1, a connecting plate 5 is hinged on the outer side of the loading plate 4 close to the end of the drone 1, the connecting plate 5 is fixed to the side of the mounting plate 2 away from the drone 1, a monitoring camera 6 is provided on the side of the loading plate 4 away from the end of the drone 1, baffles 22 are fixed on both sides of the mounting plate 2 away from the end of the loading plate 4, the two baffles 22 are used to protect the monitoring camera 6 in a deflected state, and a connecting component for connecting the monitoring camera 6 is provided on the loading plate 4.

[0032] The implementation principle of a crop growth monitoring device based on a drone in the embodiment of the present application is as follows: when it is necessary to monitor the growth of crops, the operation of the drone 1 can drive the mounting plate 2 and the monitoring camera 6 on the mounting plate 2 to move; when the monitoring camera 6 is located above the crops to be monitored, the deflection of the loading plate 4 can drive the monitoring camera 6 to deflect; when the monitoring camera 6 is located on one side of the crops to be monitored, the crops can be monitored through the monitoring camera 6; and because the drone 1 is far away from the crops to be monitored, the branches and leaves of the crops can be prevented from falling over with the rotating blades of the drone 1. When the monitoring camera 6 needs to make fine adjustments in displacement during the process of monitoring crops, the monitoring camera 6 can be driven to deflect by the deflection of the loading plate 4. At this time, the corresponding angle of the monitoring camera 6 can be adjusted. When the drone 1 is flying and does not need to monitor the crops, the monitoring camera 6 can be driven to deflect by the deflection of the loading plate 4. When the monitoring camera 6 rotates to between the two baffles 22, the two baffles 22 can be used to shield and protect the monitoring camera 6 to prevent the monitoring camera 6 from being scratched by external objects during the flight of the drone 1, causing damage to the lens of the monitoring camera 6.

[0033] Embodiment 2:

[0034] Combination Figure 4 , Figure 5 , Figure 6 and Figure 7The present embodiment is further improved on the basis of the embodiment 1 in that: the connecting assembly includes a slide groove 7 and a slider 8 sliding inside the slide groove 7, the slide groove 7 is arranged on the side of the loading plate 4 close to the monitoring camera 6, a linkage block 9 fixed on the slider 8 is slidably penetrated in the notch of the slide groove 7, the end of the linkage block 9 away from the slider 8 is fixed on the monitoring camera 6, a transmission block 10 is arranged on the side of the mounting plate 2 close to the monitoring camera 6, a driving plate 11 is hingedly connected to the outer side of the transmission block 10, and the end of the driving plate 11 away from the transmission block 10 is hingedly connected to the loading plate 4. On the outer side of the plate 4, a sample collecting column 15 is fixed on the side of the loading plate 4 close to the monitoring camera 6, and a sample collecting cavity 16 is provided at one end of the sample collecting column 15 away from the loading plate 4. A through hole connected to the sample collecting cavity 16 is provided on the outer side of the sample collecting column 15, and a cutter 17 is slidably penetrated inside the through hole, and a handle 18 is fixed to the end of the cutter 17 located outside the sample collecting cavity 16. The sample collecting column 15 is provided with a sliding hole that passes through the sample collecting cavity 16, and a sliding column 19 is slidably penetrated inside the sliding hole, and the end of the sliding column 19 close to the cutter 17 is fixed to the handle 18, and the sliding column A push block 20 is fixed to one end of 19 away from the handle 18. The displacement of the transmission block 10 drives the drive plate 11 to deflect, and drives the loading plate 4 to deflect. At this time, the corresponding position of the monitoring camera 6 can be adjusted. When the agricultural staff needs to sample the monitored crops during the process of monitoring the crops, the monitoring camera 6 is displaced. When the displaced monitoring camera 6 contacts the push block 20, the push block 20 is pushed to displace, driving the sliding column 19, the handle 18 and the cutter 17 to displace. After the knife 17 opens the opening of the sample collecting chamber 16, the sample collecting column 15 is driven to deflect through the deflection of the loading plate 4. At the same time, the drone 1 performs corresponding flight. When the crops enter the interior of the sample collecting chamber 16, the monitoring camera 6 is displaced. When the monitoring camera 6 is separated from the pushing block 20, the pushing block 20, the sliding column 19, the knife handle 18 and the cutter 17 are reset and displaced. When the cutter 17 contacts the crops to be sampled, the crops can be cut off inside the sample collecting chamber 16 by the cutter 17. At this time, the crop sampling is completed.

[0035] A sponge sheet is bonded to the inner wall of the sample receiving chamber 16, and the end of the cutter 17 located inside the sample receiving chamber 16 is in contact with the sponge sheet. The blade of the cutter 17 located inside the sample receiving chamber 16 is used to close the opening of the sample receiving chamber 16. The sponge sheet can prevent the cutter 17 from being reset and displaced from colliding hard with the inner wall of the sample receiving chamber 16, causing damage to the cutter 17.

[0036] The pushing block 20 is a circular block, which cooperates with the monitoring camera 6. The pushing block 20 is made of a flexible material. The pushing block 20 made of a flexible material can avoid a hard collision when the displaced monitoring camera 6 contacts the pushing block 20, thereby preventing the monitoring camera 6 from being damaged.

[0037] A return spring 21 is provided on the outer movable sleeve of the sliding column 19 located outside the sample collecting column 15. One end of the return spring 21 is fixed to the outer wall of the sample collecting column 15, and the other end of the return spring 21 is fixed to the pushing block 20. When the monitoring camera 6 is separated from the pushing block 20, the elasticity of the return spring 21 can push the displaced pushing block 20 and the sample collecting column 15 to reset.
