Description

Technical Field

[0001] The patent of this invention belongs to the field of agricultural information collection technology, and specifically relates to a suspended agricultural information collection device, as well as the base frame and floating air bag structure of the device. Background Art

[0002] Field management refers to the labor process of creating good conditions for the growth and development of crops. Information collection for observing the growth status of crops is a key link. By observing the color of crop leaves, pollination status, fruit maturity and other information, we can timely understand the growth status of crops. When we timely observe that the crops lack certain elements, causing the leaves to be in a sub-healthy state, and that the crops are affected by pests and diseases, causing crop withering and root corruption, we can prevent environmental factors such as fertilizer deficiency, pests and pollination problems from affecting crop yields during crop growth. After the information collection equipment finds problems, we can conduct manual intervention in a timely manner to prevent the continuous impact of environmental factors from causing crop yield reductions.

[0003] The information collection device includes a camera stabilizer, an information collection camera and an agricultural infrared camera. Infrared thermal imagers can be used to monitor the growth of crops. The growth of crops is affected by temperature. Infrared thermal imagers can quickly and non-contactly obtain temperature information on the surface of crops. By comparing the temperature differences in different areas, the health status of crops can be evaluated. By monitoring the temperature distribution of crops, farmers can promptly discover possible problems in crops, such as lack of water, disease infection, etc., and take corresponding measures to protect crops.

[0004] Take soybeans as an example. From the end of germination to maturity, they have to go through the pod-setting period, fruit-filling period, maturity period, and harvesting period, which takes a long time. In this process, there are many environmental factors that may affect the growth and maturity of crops. Information collection technology can help agricultural workers prevent problems, discover problems and intervene in time, which is an important link in field management. Infrared thermal imagers can also be used to optimize irrigation and fertilization strategies for crops. In addition, by monitoring the temperature distribution of crops, farmers can understand whether the water and nutrient requirements of different areas are balanced. In a field, infrared thermal imagers can help farmers determine the areas where crops grow most actively, so as to better irrigate and fertilize, improve resource utilization efficiency, reduce waste, and avoid environmental problems caused by excessive irrigation and fertilization.

[0005] With the development of science and technology, agricultural informationization and mechanization are the directions that my country, as a country with high crop yields, is currently pursuing and will continue to advance in the future. The advantages of using agricultural information collection equipment to collect crop growth information are: (1) It can timely obtain the growth status of crops, scientifically apply fertilizers, and improve fertilization efficiency and reduce costs while protecting the natural ecological environment; (2) The information acquisition cycle is shorter and the information collection sample range is wider, which can analyze the crop growth status more scientifically and comprehensively. Machines can replace workers for observation, liberate labor and save labor costs; (3) Through agricultural information collection, the impact of pests on crops can be discovered in time, and manual intervention can be carried out as quickly as possible to reduce crop yield reduction caused by pests. (4) Agricultural information data collection is a key step in achieving my country's goal of intelligent agriculture, including the construction of a standardized agricultural big data system. At the technical level, various sensors and monitoring equipment can be used to obtain real-time information on the growth status of crops in the field, soil moisture, pH value, pests and diseases, etc., providing accurate data support for agricultural production.

[0006] People are increasingly concerned about the quality and yield of fruits and vegetables. Timely and accurate agricultural information collection and scientific management are a strong guarantee for crop yields. Obtaining information data on a certain crop from seedling to maturity at different stages provides data support for the growth and maturity of the next cycle of crops. Exploring crop growth patterns through data collection at different stages to promote yield increases is in line with national policies and market needs.

[0007] The existing technology center uses cruise-type agricultural information collection equipment to collect information on crop growth status. Compared with fixed monitoring equipment and manual observation, it has the following three advantages: (1) Fixed monitoring equipment has a limited observation range and is far away from crops, so it cannot accurately observe the condition of leaves. For example, when the floating agricultural information collection equipment is working, it is close to the leaves and can observe the yellowing between the veins of the plant. In addition, the fixed monitoring position does not change. For the same plant, only the leaf condition on the side where the camera is located can be observed. The cruise-type agricultural information collection equipment can observe the same crop from multiple angles and directions as it moves, which can be more accurate when collecting crop growth information. (2) A single cruise-type agricultural information collection equipment can collect and manage information on a large area of ​​farmland through cruise flight. One device has a wide working coverage. The ground crawler agricultural robot has a high working difficulty because the ground conditions of the farmland are complex and the distance between crops is small. The flight posture of the cruise-type agricultural information collection equipment is relatively stable, which is convenient for information collection. (3) The scanning path of the cruise information collection camera in the field is dense and orderly, and the information acquisition accuracy is high and the effect is stable. The fixed information collection camera has blind spots in its coverage area, and the information collection is not comprehensive. The cruise information collection camera can make the information collection effect in the area high-quality and uniform. The fixed agricultural information collection camera has blind spots in its observation range, and the information acquisition effect of crops at the edge of the camera is poor. The cruise information collection camera can take close-up photos of the growth of leaves, stem tips and petals and sepals, and monitor the temperature distribution of crops through infrared cameras. Agricultural workers can promptly discover problems such as insufficient water and disease infection in crops. This makes crop information collection more accurate. Considering the above, it is very necessary to use cruise agricultural information collection equipment for crop information collection and processing.

[0008] Chinese patent (CN202320412535.4) discloses an agricultural information collection device, and Chinese patent (CN202330004639.7) discloses an agricultural information collection machine; however, the equipment capable of completing agricultural information collection in the existing technology center also has shortcomings in actual use. The fixed camera has a large distance when completing agricultural information collection, and there is a blind spot in the viewing angle when collecting information on crop growth. It can only observe the growth status of one side of the crop, and when observing crops arranged in dense multi-ridges, the crops in the front ridge will block the crops behind, affecting the quality of information collection of the crops in the back row. Chinese patent (CN107150805A) discloses a day and night dual-use drone; Chinese patent (CN107662706A) discloses a drone; however, the equipment capable of completing cruising in the existing technology center also has shortcomings in actual use. When the aircraft drives the agricultural information collection equipment to complete the cruising work, the power consumption is large, and the power consumption of the equipment's own information collection camera and other components will result in a short cruising time for the entire equipment and insufficient working time.

[0009] Therefore, the applicant has designed and developed a suspended agricultural information collection equipment, including an information collection device, an upper stabilizing platform and a bottom frame structure. The information collection equipment is arranged below the double-layer composite mounting plate in the middle of the frame, and an upper stabilizing platform is also provided on the outside of the airbag, and a rotor device is provided on the platform. The device is characterized in that a floating air bag is also connected to the frame.

[0010] However, how the upper stabilizing platform and the base structure should be designed to have a simple structure and to more conveniently integrate the information collection equipment, the rotor device and the floating air bag has become a technical problem that needs to be further solved. Summary of the invention

[0011] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the patent of this invention is: how to provide a frame structure and a floating air bag structure of a suspended agricultural information collection device with a simple structure that can more conveniently combine the information collection equipment, the rotor device and the floating air bag into one.

[0012] In order to solve the above technical problems, the present invention adopts the following technical solutions: A frame structure of a suspended agricultural information collection equipment, comprising an upper annular stabilizing platform connected to an airbag, and a bottom frame having an overall octagonal structure. The structure is characterized in that four pairs of downwardly disposed landing gears are arranged at equal intervals on the lower end surface of the octagonal frame, and a two-layer mounting frame is formed by connecting members on the inner side of the octagonal frame and between the four pairs of landing gears. The lower end of the mounting frame is used to install and fix an agricultural information collection camera, and the lower end surface of the landing gear extends downward beyond the height position of the lower end surface of the agricultural information collection camera.

[0013] In this way, the frame has a bottom frame at the lower end, and 4 pairs of landing gears are arranged at the lower end of the bottom octagonal frame. A two-layer installation frame is formed in the middle position of the bottom octagonal frame, and the lower end surface of the second-layer installation frame is fixed with the agricultural information collection device, and then the lower end surface of the landing gear is downwardly extended beyond the height position of the lower end surface of the information collection device; such a structure makes the entire structure simpler, the equipment as a whole is more compact, and it is convenient to install the agricultural information collection camera; and when the entire device is taking off and landing, and when working, the landing gear can effectively prevent the agricultural information collection device from being hit and disturbed, and can improve the clarity and accuracy of information collection.

[0014] As an optimization, in the bottom frame structure, the landing gear includes 4 pairs of load-bearing rods with the lower ends inclined and bent inward; each pair of load-bearing rods are parallel to each other and arranged at equal intervals, and each load-bearing rod is subjected to more uniform force, and the pressure on each load-bearing rod is smaller after the force is dispersed.

[0015] In this way, the structure of the landing gear is simpler, and the equipment can be more stable when landing. Further, the two ends of the load-bearing rod extend outwards and the projection in the horizontal direction exceeds the lower octagonal base frame. This makes the whole equipment more stable and more stable when docked.

[0016] As an optimization, an upper stabilizing platform of a suspended agricultural information collection device is provided, wherein the four corner positions on the upper end surface of the stabilizing platform are respectively connected and fixed with a rotor support plane arranged horizontally outward, and the upper end of the support plane forms a mounting end and is equipped with a high-speed DC motor and a lifting rotor.

[0017] In this way, by setting four outward fixing plates that are closely attached to the floating air bag and are evenly spaced on the lower side of the floating air bag, the outer side of the fixing plate forms a connecting bracket that is in contact and connected with the four supporting planes on which the lifting rotor is installed, which has the advantages of simple structure and convenient installation and arrangement of the lifting rotor. When the entire device is working, the floating air bag offsets or partially offsets the gravity of the base and the information collection device, and then the lifting rotor drives the entire device to lift off and work. Specifically, the lifting rotor includes a driving motor vertically installed on four supporting planes, and the upper end of the driving motor is a power output end and is transmission-connected to the lifting rotor blades.

[0018] As an optimization, the rotor support plane and the upper end surface of the annular structure of the upper stabilizing platform of the suspended agricultural information collection equipment are parallel to each other, so that any two support planes are arranged parallel to each other.

[0019] In this way, the setting is more reasonable, the upward lift force provided by the lifting rotor at the outer end of the upper stable platform is more stable, and the mutual influence between the lifting rotors is smaller.

[0020] As an optimization, the upper stabilizing platform and the lower octagonal frame structure are connected by four cables vertically arranged on the outside of the airbag. The lower end of the cable is connected to the motor of the bottom frame, and the upper end of the connecting rod is connected to the wire reel of the floating airbag.

[0021] In this way, it is convenient to connect the base frame with the floating air bag, and the lower platform is kept in a horizontal state by controlling the tightening and loosening of the cable through the motor to ensure the stability of the information collection camera, and the structure is simple.

[0022] As an optimization, the number of the connecting cables is four and they are arranged in a circle with equal angles.

[0023] In this way, the connection between the lower base frame and the floating air bag of the upper stabilizing platform is more reliable and more stable.

[0024] As an optimization, the base frame also includes a mounting frame at the upper end, the mounting frame includes a ring-shaped fixed plate, the inner surface of the fixed plate forms an airbag connecting surface and is used to be connected to the floating air bag; the outer surface of the fixed plate forms a rotor mounting surface; the rotor device also includes a steering rotor and a driving rotor; a steering rotor is respectively installed on the left and right sides of the rotor mounting surface to drive the floating air bag to rotate horizontally, and a driving rotor is respectively installed on the front and rear sides of the rotor mounting surface to drive the floating air bag to move horizontally.

[0025] As an optimization, the upper stabilizing platform of the suspended agricultural information collection equipment also includes a mounting frame located outside the airbag, and the inner side of the mounting frame is connected to four fixed plates that are evenly spaced and circumferentially distributed and have a spherical structure as a whole. The inner surface of the fixed plate forms an airbag connecting surface and is used to be connected to the floating airbag; the outer surface of the fixed plate forms a contact connection with the rotor support plane; the four rotors on the four rotor support platforms of the rotor mounting surface form a torque by increasing the rotation speed of the two rotors on the diagonal line to drive the floating airbag to rotate horizontally, and by increasing the rotation speed of the two adjacent rotors, the upper stabilizing platform is tilted forward to drive the floating airbag to move horizontally.

[0026] In this way, the fixed plate and the floating air bag are closely connected, so that the connection between the two is reliable, and the fixed plate can support the floating air bag, so that the floating air bag can better maintain its shape; and the outer surface of the fixed plate can be connected to the stable rotor support plane to form a rotor installation surface that can facilitate the installation of four lifting rotors. Because the volume of the floating air bag is often larger than that of the base frame and the information collection device, the floating air bag is also subject to greater resistance when the equipment is working. The rotors that control the lifting and steering are correspondingly set on the rotor support plane of the upper stable platform, which can better complete the steering and driving of the entire equipment; the set support plane can be more convenient for the installation of the corresponding four rotors.

[0027] As an optimization, the bottom base frame includes an octagonal base frame body with weight-reducing holes arranged on the sides, and a rectangular mounting plate with a double-layer structure having multiple mounting holes and weight-reducing holes is connected to the inside of the base frame body.

[0028] In this way, the entire bottom frame structure is simpler and can achieve the effect of reducing weight.

[0029] The patent of the present invention also discloses a floating air bag structure of a suspended agricultural information collection device, which is characterized in that it includes a floating air bag, and four circular and evenly spaced fixed plates are provided on the lower side of the floating air bag. The inner surface of the fixed plate forms an air bag connecting surface and is used to be connected to the floating air bag; the outer surface of the fixed plate forms a connecting bracket that is in contact with the rotor support plane; the four rotors on the four rotor support platforms of the rotor mounting surface form a torque by increasing the rotation speed of the two rotors on the diagonal line to drive the floating air bag to rotate horizontally, and by increasing the rotation speed of the two adjacent rotors, the upper stabilizing platform is tilted forward to drive the floating air bag to move horizontally.

[0030] In this way, the fixed plate and the floating air bag are closely connected, so that the connection between the two is reliable, and the fixed plate can support the floating air bag, so that the floating air bag can better maintain its shape; and the outer surface of the fixed plate can form a rotor installation surface, which can facilitate the installation of the steering rotor and the driving rotor. Because the volume of the floating air bag is often larger than that of the base frame and the information collection device, the floating air bag is subject to greater resistance when the equipment is working. The steering rotor and the driving rotor are correspondingly arranged on the floating air bag, which can better complete the steering and driving of the entire equipment; the set support plane can more conveniently install the corresponding four rotors.

[0031] As an optimization, the angles between the lines connecting the four lifting rotors and the central axis are right angles to each other.

[0032] In this way, the positions of the four rising rotors arranged perpendicular to each other are more reasonable, and can more smoothly drive the entire device to turn and drive the entire device to operate.

[0033] As an optimization, weight-reducing holes and mounting holes are provided on the double-layer mounting plate and the octagonal bottom base frame.

[0034] In this way, by arranging weight-reducing holes on the double-layer composite mounting plate, the weight of the equipment can be reduced, the load during operation can be reduced, and the cruising capability of the equipment can be increased.

[0035] As an optimization, the weight-reducing holes on the rectangular mounting plate include six first weight-reducing holes arranged in a long strip on the left and right sides of the mounting plate and arranged at equal intervals at an angle of 30 degrees along the length direction of the mounting plate, and corresponding second weight-reducing holes arranged in a rectangular structure between the first weight-reducing holes on the left and right sides, parallel to the length direction of the mounting plate and arranged at equal intervals; and two columns of 11 second weight-reducing holes are evenly arranged between the first weight-reducing holes arranged in an array on the left and right sides; two vertical mounting holes are formed between the two columns of second weight-reducing holes for installing batteries, single-chip microcomputers and agricultural information collection cameras that drive the rotation of the lifting rotor. Five third weight-reducing holes are arranged on each of the four long opposite sides of the octagonal bottom frame, and four fourth weight-reducing holes and two second mounting holes are arranged on each of the four short opposite sides for installation and connection between the octagonal bottom frame and the eight landing gears.

[0036] By machining mounting holes on the rotor support plane, a rotor motor is installed in the mounting hole, which facilitates the installation of the four lifting rotors. Furthermore, the rotor support plane is parallel to the upper surface of the upper stabilizing platform in an annular structure, so that any two support planes are arranged parallel to each other, and the device is in a more stable state when the rotor is working. The outer end of the drive motor is the power output end and is transmission-connected to the rotor blades. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The present invention is further described in detail below in conjunction with the accompanying drawings of a suspendable agricultural information collection device that uses the patent structure of the present invention.

[0043] When implementing: Figures 1 to 5 As shown, a suspended agricultural information collection device includes an information collection device 15, an upper stabilizing platform 5 and a bottom frame structure 7. The information collection device is arranged below the frame, and four rotor devices 3 are also arranged on the upper stabilizing platform. A floating air bag 10 is also connected to the upper stabilizing platform.

[0044] In this way, when the above-mentioned suspended agricultural information collection equipment is in use, the floating air bag connected to the bottom frame can generate an upward lifting force to offset or partially offset the gravity of the frame and the information collection device; the floating air bag is combined with the rotor device, because the upward lifting force of the floating air bag can offset the gravity of the frame and the information collection device, the rotor device then controls the overall operation of the equipment to complete the cruise, which can save electricity, improve the cruising ability of the equipment, and make the equipment last longer after one power supply or charging. In specific implementation, helium is set in the floating air bag, so that the floating air bag can better provide lifting force.

[0045] In this specific implementation, the information collection device 15 includes an information collection camera, an agricultural infrared camera, and a camera stabilizer.

[0046] Thus, the information collection device includes a camera stabilizer, an information collection camera, and an agricultural infrared camera. The camera stabilizer prevents the camera from shaking, keeps the equipment stable during the collection process, and controls the camera to rotate as required to ensure comprehensive and efficient collection of crop growth information. The infrared camera can be used to monitor the growth status of crops. The growth of crops is affected by temperature. The infrared thermal imager can quickly and non-contactly obtain the temperature information of the crop surface. By comparing the temperature differences in different areas, the health status of the crop can be evaluated. By monitoring the temperature distribution of crops, farmers can promptly discover possible problems in crops, such as lack of water, disease infection, etc., and take corresponding measures to protect the crops.

[0047] During implementation, the information collection device is connected to a battery installed above the double-layer base frame and powered by the battery. The battery also supplies power to the rotor device.

[0048] In this specific embodiment, the floating air bag 10 includes an air bag body and helium gas filled in the air bag body.

[0049] In this way, the floating airbag can better provide upward lifting force to better offset or partially offset the gravity of the information collection device and the bottom base frame, and can better improve the continuous cruising ability of the equipment. Specifically, the airbag body is made of soft PVC material.

[0050] In this specific embodiment, the upward lifting force generated by the floating air bag 10 is equal to the sum of the gravity of all the base frames and the agricultural information collection device.

[0051] In this way, the upward lifting force generated by the airbag is equal to the sum of the gravity of the base frame and the information collection device, which can better offset the gravity of the information collection device and the base frame. The battery power of the drone is not used to offset the gravity of the equipment, which can better improve the equipment's ability to cruise continuously.

[0052] In this specific embodiment, the frame includes a bottom frame 7 with an overall octagonal structure, and 4 pairs of downwardly disposed landing gears 9 are arranged at equal intervals on the lower end surface of the octagonal frame. The inner side of the octagonal frame is formed with a two-layer mounting frame 14 by a connecting piece 13. The lower end of the mounting plane is used to install and fix an agricultural information collection camera 15, and the lower end surface of the landing gear is downward and exceeds the height position of the lower end surface of the agricultural information collection camera.

[0053] In this way, the frame comprises a bottom frame and a two-layer mounting frame in the middle of the bottom frame, and landing gears are arranged in pairs at the lower end of the bottom frame, and the lower end surfaces of the two-layer mounting frames are set as mounting planes and the information collection device is installed and fixed thereon, and then the lower end surface of the landing gear is made to extend downward beyond the height position where the lower end surface of the information collection device is located; such a structure makes the entire structure simpler, the overall equipment more compact, and it is convenient to install the information collection device; and when the entire device is taking off and landing, and when working, the landing gear can effectively prevent the agricultural information collection device from being hit and disturbed, and can improve the clarity and effect of information collection.

[0054] In this specific embodiment, the landing gear 9 includes 4 pairs of load-bearing rods with the lower ends tilted inwardly bent, each pair of load-bearing rods are parallel to each other and arranged at equal intervals; and the projection of the load-bearing rods in the horizontal direction is located outside the horizontal projection of the bottom frame.

[0055] In this way, the structure of the landing gear is simpler, and the device can be more stable when landing. Specifically, the two ends of the load-bearing rod extend outwards and the projection in the horizontal direction exceeds the octagonal bottom frame setting. This makes the stability of the device better.

[0056] In this specific embodiment, the rotor device includes a lifting rotor 3; the four corner positions on the upper end surface of the stabilizing platform are each connected and fixed with a rotor support plane 4 arranged horizontally and outwardly, and the upper end of the support plane forms a mounting end and is equipped with a high-speed DC motor and a lifting rotor.

[0057] In this way, by setting four horizontal outward supporting planes on the upper end surface of the upper stable platform, the outer end of the supporting plane forms a mounting structure for mounting the lifting rotor, which has the advantages of simple structure and convenient installation and arrangement of the lifting rotor. When the entire device is working, the floating air bag offsets or partially offsets the gravity of the base and the information collection device, and then the lifting rotor drives the entire device to lift off and work. Specifically, the lifting rotor includes a drive motor vertically mounted on the outer end of the supporting plane, and the upper end of the drive motor is the power output end and is transmission-connected to the lifting rotor blades.

[0058] In this specific implementation, the rotor support plane 4 is parallel to the upper end surface of the upper stabilizing platform in an annular structure, so that any two support planes are arranged parallel to each other.

[0059] In this way, the arrangement is more reasonable, the upward lift force provided by the lifting rotors at the outer ends of the supporting plane is more stable, and the mutual influence between the lifting rotors is smaller.

[0060] In this specific embodiment, the bottom base frame 7 of the octagonal structure includes a connecting rope 2 vertically arranged in the middle, the lower end of the connecting rope is fixedly connected to the stepping motor 8 on the bottom base frame, and the upper end of the connecting rope is used to connect to the wire reel 1 on the floating air bag 10.

[0061] In this way, it is convenient to connect the bottom base frame with the floating air bag, and the structure is simple.

[0062] In this specific implementation manner, the connecting ropes are four arranged at equal angles in a square.

[0063] In this way, the connection between the bottom base frame and the upper floating air bag is more reliable and more stable.

[0064] In this specific embodiment, the stabilizing platform also includes a mounting frame 6 located outside the airbag, and four equally spaced circumferentially distributed fixing plates 11 with an overall spherical structure are connected to the inner side of the mounting frame. The inner surface of the fixing plate forms an airbag connecting surface and is used to be connected to the floating airbag 10; the outer side surface of the fixing plate forms a contact connection with the rotor support plane; the four rotors on the four rotor support platforms of the rotor mounting surface form a torque by increasing the rotation speed of the two rotors on the diagonal line to drive the floating airbag to rotate horizontally, and by increasing the rotation speed of the two adjacent rotors, the upper stabilizing platform is tilted forward to drive the floating airbag to move horizontally; the bottom frame includes an octagonal frame body at the upper end, and a rectangular and double-layer mounting plate 14 is connected to the inner side of the frame body, and an agricultural information collection camera 15 is installed under the mounting plate.

[0065] In this way, the fixed plate and the floating air bag are closely connected, so that the connection between the two is reliable, and the fixed plate can support the floating air bag, so that the floating air bag can better maintain its shape; and the outer surface of the fixed plate can be connected to the stable rotor support plane 4 to form a rotor installation surface that can facilitate the installation of four lifting rotors. Because the volume of the floating air bag is often larger than the volume of the base frame and the information collection device, the floating air bag is also subject to greater resistance when the equipment is working. The rotors that control the lifting and steering are correspondingly set on the rotor support plane of the upper stable platform, which can better complete the steering and driving of the entire equipment; the set support plane can be more convenient to install the corresponding four rotors. In specific implementation, the horizontal rotation of the equipment and the steering are achieved by differentially rotating two steering rotors in pairs, which has the advantages of simple and reliable steering structure.

[0066] In this specific embodiment, the angle between the lines connecting the four lifting rotors 3 and the central axis of the spherical airbag is a right angle.

[0067] In this way, the positions of the four rising rotors arranged perpendicular to each other are more reasonable, and can more smoothly drive the entire device to turn and drive the entire device to operate.

[0068] Weight reduction holes and mounting holes are provided on the rectangular double-layer composite mounting plate 14 and the octagonal bottom base frame 7 .

[0069] In this way, by arranging weight-reducing holes on the double-layer composite mounting plate, the weight of the equipment can be reduced, the load during operation can be reduced, and the cruising capability of the equipment can be increased.

[0070] The weight-reducing holes on the rectangular double-layer composite mounting plate include six first weight-reducing holes arranged in a long strip on the left and right sides of the mounting plate and arranged at equal intervals at an angle of 30 degrees along the length direction of the mounting plate, and also include corresponding second weight-reducing holes arranged in a rectangular structure between the first weight-reducing holes on the left and right sides, parallel to the length direction of the mounting plate and arranged at equal intervals; and two columns of 11 second weight-reducing holes are evenly arranged between the first weight-reducing holes arranged in an array on the left and right sides; two vertical mounting holes are formed between the two columns of second weight-reducing holes for installing batteries, single-chip microcomputers and agricultural information collection cameras that drive the rotation of the lifting rotor. Five third weight-reducing holes are arranged on each of the four long opposite sides of the octagonal bottom base frame, and four fourth weight-reducing holes and two second mounting holes are arranged on each of the four short opposite sides, which are used for the installation connection between the octagonal bottom base frame 7 and the eight load-bearing brackets 9.

[0071] In this way, by machining a mounting hole on the rotor support plane and installing a rotor motor in the mounting hole, it is convenient to install the four lifting rotors. Furthermore, the rotor support plane is parallel to the upper surface of the upper stabilizing platform in an annular structure, so that any two support planes are arranged parallel to each other, and the device is in a more stable state when the rotor is working. The outer end of the drive motor is the power output end and is transmission-connected to the rotor blades.
