Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle fertilization, in particular to a quick-install structure of a fertilization bin of an unmanned aerial vehicle. Background Art

[0002] At present, drones have been widely used in the agricultural field, including the use of drones to fertilize crops, spray pesticides, and sow seeds. The existing technology mainly adopts a structure that integrates drones and silos. The drone needs to land and wait for new materials to be added, and the work efficiency is low. Another method is to use a structure where the drone and the silo are separated. When the silo is emptied, the drone can return to the ground to replace the silo. After replacing the silo, it can take off and operate without waiting for new materials to be added, which can improve the operation efficiency of the drone. However, in the existing technology of the split structure, the installation and dismantling structure design is complex, and most of them use traditional mechanical structures, which require manual and complicated operations under the machine to complete the disassembly and assembly of the silo.

[0003] For example, Chinese patent CN212766755U discloses a split-type agricultural spraying drone medicine barrel, including a barrel body, a liquid inlet is provided at the upper end of the barrel body, a discharge port is provided at the bottom of the barrel body, and connecting arms are fixed on the outer walls of the barrel body. The connecting arms of the barrel body are detachably connected to the drone platform or the drone arm, and the specific implementation methods include buckles, straps, etc. Chinese patent CN216102790U discloses a plant protection drone with a detachable drug-carrying bin, including a plant protection drone body, connecting wings are provided at the four corners of the plant protection drone body, a driving mechanism is provided at the farthest end of the connecting wing, a fixing plate is fixedly connected to the lower surface of the plant protection drone body, a disassembly slot is provided at the front end of the fixing plate, and a sliding plate is slidably connected to the inside of the disassembly slot, and the specific operation requires the staff to unscrew the hexagonal nut from the locking rod and remove it from the lock hole, and pull the disassembly handle by hand to drive the drug-carrying bin and the sliding plate from the disassembly slot, insert the locking rod into the lock hole again, and use the hexagonal nut to lock it. In the above-mentioned prior art, workers are required to carry out complicated disassembly and assembly operations under the machine, the disassembly and assembly efficiency is low, and the disassembly and assembly structure is complicated. Utility Model Content

[0004] In view of the above problems, the utility model provides a quick-assembly structure of a UAV fertilizer silo, aiming to solve the problems that the existing UAV and silo disassembly and assembly structure requires workers to operate the disassembly and assembly under the UAV, the disassembly and assembly efficiency is low, and the disassembly and assembly structure is complicated.

[0005] The utility model adopts the following technical solutions to achieve the above purpose:

[0006] A quick-install structure for a fertilizer silo for an unmanned aerial vehicle, which is used to install the silo on the bottom of the unmanned aerial vehicle; the quick-install structure includes a hydraulic mechanism installed on the bottom of the unmanned aerial vehicle and a lifting ring group fixed on the top surface of the silo; the unmanned aerial vehicle includes a fuselage and two support frames respectively connected to the bottom of the fuselage on both sides; the lifting ring group is arranged at positions corresponding to the two support frames, and more than two lifting rings are arranged at positions corresponding to each support frame, and the lower wall of each support frame is also provided with a cavity for accommodating the lifting ring; the hydraulic mechanism includes a hydraulic cylinder, a three-position four-way reversing valve, an oil pump and an oil cylinder, and the hydraulic cylinder includes a rodless cavity, a rod cavity and a hydraulic rod; one end of the three-position four-way reversing valve is connected to the rodless cavity and the rod cavity respectively through two oil pipes, and the other end is connected to the oil pump and the oil cylinder respectively through two oil pipes; the lifting ring is provided with a through hole matching the hydraulic rod; the hydraulic cylinder is installed on a side wall on one side opposite to the lifting ring through hole in the cavity, and the other side wall is provided with a groove matching the hydraulic rod.

[0007] In this technical solution, the hydraulic rod in the hydraulic mechanism passes through the corresponding lifting ring to quickly connect the silo to the bottom of the drone. The staff only needs to operate the corresponding valve position in the hydraulic mechanism to power on or off to complete the disassembly and assembly, which can improve the efficiency of disassembly and assembly of the silo. At the same time, when the drone is working in a large area, the silo can be quickly replaced to improve the operation efficiency of the drone. The disassembly and assembly process of this technical solution is as follows: at the initial moment, the hydraulic rod retracts inside the hydraulic cylinder, that is, the hydraulic rod is located in the inner wall of the cavity, and the three-position four-way reversing valve is in the middle valve position. During the installation process, the drone is driven to land above the silo, and the lifting ring is located in the corresponding cavity. The left valve position of the three-position four-way reversing valve is energized (that is, the left valve position is connected to the hydraulic pipeline), and the oil pump supplies oil to the rodless cavity, and the rod cavity returns oil to the oil cylinder. At this time, the hydraulic rod extends and passes through the through hole of the lifting ring to cooperate with the groove, and the three-position four-way reversing valve is powered off. It is in the middle valve position, which means that the installation of the silo and the drone is completed. When the silo is emptied and needs to be replaced, the drone falls back to the ground, and the right valve position of the three-position four-way reversing valve is energized (that is, the right valve position is connected to the hydraulic pipeline). The oil pump supplies oil to the rod chamber, and the rodless chamber returns oil to the cylinder. The hydraulic rod retracts to the inner wall of the cavity, and the three-position four-way reversing valve is de-energized, so that it is in the middle valve position, which completes the disassembly of the silo and the drone. At this time, the drone is in the initial state, and the above installation process can be repeated to complete the installation of the new silo.

[0008] A further technical solution is that the upper wall of the cavity is an arched structure along the outer ring direction of the lifting ring. In this technical solution, when the drone lands on the top of the silo and there is a small deviation, the arched structure of the cavity can slide along the outer wall of the lifting ring, so that the lifting ring through hole is located on the trajectory of the hydraulic rod extending, thereby improving the fault tolerance of the quick-installation structure.

[0009] A further technical solution is that the end of the hydraulic rod is a conical structure. In this technical solution, when the drone lands on the top of the silo and there is a small deviation, the conical end of the hydraulic rod will contact the inner wall of the lifting ring during the extension process, driving the drone to correct the deviation and improve the fault tolerance of the quick-install structure.

[0010] A further technical solution is that the upper wall of the silo is also provided with a limit groove, and the inner walls on both sides of the limit groove are inclined surfaces that cooperate with the two support frames, and the inclined surfaces are inclined from top to bottom toward the middle of the limit groove; the outer wall where the support frame cooperates with the inner wall of the limit groove is also provided with a corresponding inclined surface. In this technical solution, when a deviation (deviation on both sides) occurs during the landing of the drone, the bottom of the support frame on one side contacts the side wall of the limit groove and slides downward along the inclined surface of the side wall, so that the lifting ring enters the corresponding cavity, thereby improving the fault tolerance of the quick-install structure.

[0011] The beneficial effects of the utility model are:

[0012] The utility model discloses a quick-install structure for a fertilizer silo of an unmanned aerial vehicle, in which a hydraulic rod in a hydraulic mechanism penetrates a corresponding lifting ring to quickly connect the silo to the bottom of the unmanned aerial vehicle. Workers only need to operate a corresponding valve position in the hydraulic mechanism to power on or off to complete the disassembly and assembly, thereby improving the disassembly and assembly efficiency of the silo. At the same time, when the unmanned aerial vehicle is operating in a large area, the silo can be quickly replaced to improve the operating efficiency of the unmanned aerial vehicle. The fault tolerance rate of the quick-install structure is improved by improving the cavity structure, the hydraulic rod structure, the silo upper wall structure, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In this embodiment, the hydraulic rod 33 in the hydraulic mechanism passes through the corresponding lifting ring to quickly connect the silo 2 to the bottom of the drone 1.

At the same time, the drone 1 can quickly replace the silo 2 in a large-area operation condition, thereby improving the operation efficiency of the drone 1. The disassembly and assembly process is as follows: at the initial moment, each hydraulic rod 33 is retracted inside the hydraulic cylinder 3, that is, the hydraulic rod 33 is located in the inner wall of the corresponding cavity, and the three-position four-way reversing valve 4 is not powered on and is in the middle valve position 41; during the installation process, the drone 1 is driven to land above the silo 2, the lifting ring is located in the corresponding cavity, the left valve position 42 of the three-position four-way reversing valve 4 is powered on (that is, the left valve position 42 is connected to the hydraulic pipeline), the oil pump 5 supplies oil to the rodless cavity 31, and the rod cavity 32 returns oil to the oil cylinder 5. At this time, the hydraulic rod 33 extends and passes through the through hole of the lifting ring to cooperate with the groove, and the three-position four-way reversing valve 4 is powered off, making it in the middle position. At the middle valve position 41, the installation of the silo 2 and the drone 1 is completed; when the silo 2 is emptied and needs to be replaced with a new silo, the drone 1 falls back to the ground, and the right valve position 43 of the three-position four-way reversing valve 4 is energized (that is, the right valve position 43 is connected to the hydraulic pipeline), the oil pump 5 supplies oil to the rod chamber 32, and the rodless chamber 31 returns oil to the cylinder 6, the hydraulic rod 33 retracts to the inner wall of the cavity, and the three-position four-way reversing valve 4 is de-energized so that it is located in the middle valve position 41, that is, the disassembly of the silo and the drone is completed.

When the drone 1 lands on the top of the silo 2 and a small deviation occurs (deviation along the outer ring direction of the lifting ring), the arched structure of the cavity can slide along the outer wall of the lifting ring, so that the lifting ring through hole is located on the trajectory of the extension of the hydraulic rod 33, thereby improving the fault tolerance of the quick-installation structure.

[0021] In another embodiment, based on the above embodiment, the end of the hydraulic rod 33 is a conical structure. When the UAV 1 lands on the top of the silo 2 and a small deviation occurs (deviation along the outer ring direction of the lifting ring), the conical end of the hydraulic rod 33 will contact the inner wall of the lifting ring during the extension process, driving the UAV 1 to correct the deviation and improve the fault tolerance of the quick-install structure.

[0022] Another implementation mode, based on the above implementation mode, is as follows Figure 4As shown, the upper wall of the silo 2 is also provided with a limit groove 20, and the first side wall 201 and the second side wall 202 of the limit groove 20 are inclined surfaces cooperating with the first support frame 11 and the second support frame 12 respectively, and the inclined surfaces are inclined from top to bottom toward the middle of the limit groove 20; the outer wall where the support frame cooperates with the inner wall of the limit groove is also provided with a corresponding inclined surface, that is, the outer wall of the first support frame 11 is provided with an inclined surface cooperating with the first side wall 201, and the outer wall of the second support frame 12 is provided with an inclined surface cooperating with the second side wall 202; in this embodiment, when a deviation (deviation on both sides) occurs during the landing of the drone 1, the bottom of the support frame on one side contacts the side wall of the limit groove and slides downward along the inclined surface of the side wall, so that the lifting ring enters the corresponding cavity, thereby improving the fault tolerance of the quick-installation structure.
