Description

Technical Field

[0001] The utility model relates to the technical field of release mechanisms, in particular to a drone release mechanism. Background Art

[0002] The drone release mechanism is a device designed specifically for drones, aiming to achieve precise and efficient spraying and release of drugs. With the development of modern agriculture and the continuous progress of drone technology, the liquid medicine release mechanism is increasingly widely used in fields such as crop protection and pest control. This mechanism mainly consists of a liquid medicine storage tank, a nozzle, and a release control system. The liquid medicine storage tank is used to store pesticides or fertilizers, the nozzle is responsible for evenly releasing the liquid medicine in the form of atomization or drip irrigation onto the crops, and the release control system is precisely controlled through the flight control system of the drone to ensure that the liquid medicine can be released at the appropriate height and speed according to the set parameters. With the further development of technology, the drone liquid medicine release mechanism will continue to be improved, and its application scope will also be more extensive. Its potential in fields such as intelligent agriculture and ecological environmental protection cannot be underestimated.

[0003] When the drone release mechanism is in use, it usually needs to be fixedly connected to the drone first. Some existing drone release mechanisms are connected to the drone through bolts. However, bolts are usually arranged in multiple numbers, resulting in the need to spend more time installing and disassembling the drone release mechanism, thus affecting the actual spraying time of the drugs. Therefore, this problem needs to be solved. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a drone release mechanism to solve the shortcomings existing in the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The drone release mechanism includes a bottom plate. Four installation grooves are opened at the top of the bottom plate. Four telescopic cylinders are fixedly connected to the bottom of the bottom plate. The four telescopic cylinders are evenly and fixedly arranged in a square shape. The same connecting plate is fixedly connected to the bottoms of the four telescopic cylinders. A reset mechanism for resetting the connecting plate is provided on the surfaces of the four telescopic cylinders. A medicine storage cylinder is provided at the bottom of the connecting plate. A second docking groove is opened at the top of the connecting plate. A second docking block is slidably connected inside the second docking groove. The second docking block is fixedly connected to the top of the medicine storage cylinder. Two receiving grooves are symmetrically opened on the surface of the second docking block. A constraint mechanism for constraining the medicine storage cylinder is provided inside each of the two receiving grooves. Four first docking blocks are fixedly connected to the top of the medicine storage cylinder. The four first docking blocks are evenly and fixedly arranged in a ring shape. A locking mechanism for locking the medicine storage cylinder is provided on one side of each of the four first docking blocks. Through the setting of the docking blocks, the medicine storage cylinder can be quickly connected to the drone.

[0007] As a further solution of the utility model, the reset mechanism includes a tension spring sleeved on the surface of the telescopic cylinder. The top end of the tension spring is fixedly connected to the bottom of the bottom plate, and the bottom end of the tension spring is fixedly connected to the top of the connecting plate. By setting the tension spring, the connecting plate can be reset.

[0008] As a further solution of the utility model, the restraint mechanism includes a restraint block slidably connected inside the storage groove and cooperating with the connecting plate. A second limiting rod is slidably connected to the surface of the restraint block on the side away from the first docking block. The second limiting rod is fixedly connected to one side inside the storage groove. A second spring is sleeved on the surface of the second limiting rod. One end of the second spring is fixedly connected to one side of the restraint block, and the other end of the second spring is fixedly connected to one side inside the storage groove. By setting the restraint block, the connecting plate can be restrained.

[0009] As a further solution of the utility model, the locking mechanism includes a first docking groove opened on the top of the connecting plate. The first docking block is slidably connected inside the first docking groove. Two first limiting rods are symmetrically and fixedly connected to the top of the connecting plate near the first docking groove. The same clamping block is sleeved on the surfaces of the two first limiting rods. A clamping groove is opened on the surface of the first docking block near the clamping block. The clamping block is slidably connected inside the clamping groove. Two locking grooves are symmetrically opened on one side inside the clamping groove. A tongue is slidably connected inside each of the two storage grooves. The two tongues are fixedly connected to one side of the clamping block. Adjusting mechanisms for adjusting the clamping block are provided on the surfaces of the two first limiting rods. By setting the clamping block, the medicine storage cylinder can be locked.

[0010] As a further solution of the utility model, the adjusting mechanism includes a first spring sleeved on the surface of the first limiting rod. One end of the first spring is fixedly connected to one side of the clamping block, and the other end of the first spring is fixedly connected to one side of the top of the connecting plate. A U-shaped block is fixedly connected to the top of the connecting plate near the first docking groove. A pull rope is slidably connected inside the U-shaped block. One end of the pull rope is fixedly connected to the bottom of the bottom plate, and the other end of the pull rope is fixedly connected to one side of the clamping block. A first liquid inlet is opened on the surface of the medicine storage cylinder near the connecting plate. A second liquid inlet is opened on the surface of the medicine storage cylinder away from the first liquid inlet. Two diversion ports are symmetrically opened on the surface of the medicine storage cylinder away from the connecting plate. By setting the pull rope, the clamping block can be adjusted.

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

[0012] 1. Since the utility model adopts the technical scheme of connecting and fixing with the unmanned aerial vehicle (UAV) through the docking block, the medicine storage cylinder can be quickly connected to the UAV, thus effectively solving the problem that some existing UAV release mechanisms are connected to the UAV through bolts. However, the bolts are usually arranged in multiple numbers, resulting in a relatively long time-consuming process for installing and disassembling the UAV release mechanism, which affects the actual spraying time of the medicine. A card slot is opened on one side of the first docking block, and the card slot cooperates with the card block. As the movement progresses, the card block will enter the inside of the card slot to achieve the purpose of restraining and fixing the medicine storage cylinder and prevent it from falling off. Since the medicine storage cylinder is connected to the UAV through the first docking block and the second docking block, a large amount of work can be saved during use, enabling a higher efficiency of liquid medicine spraying.

[0024] Referring to Figures 2-5, in a preferred embodiment, the locking mechanism includes a first docking groove 201. The first docking groove 201 is opened at the top of the connecting plate 2. The first docking block 304 is slidably connected to the inside of the first docking groove 201. Two first limiting rods 203 are symmetrically and fixedly connected to the top of the connecting plate 2 near one side of the first docking groove 201. The same clamping block 204 is sleeved on the surfaces of the two first limiting rods 203. A clamping groove 305 is opened on the surface of the first docking block 304 near the clamping block 204. The clamping block 204 is slidably connected to the inside of the clamping groove 305. Two locking grooves 306 are symmetrically opened on one side inside the clamping groove 305.

[0025] Refer to Figure 3 and Figure 5 , in a preferred embodiment, the adjusting mechanism includes a first spring 205. The first spring 205 is sleeved on the surface of the first limiting rod 203.

Through the arrangement of the pulling rope 206, the clamping block 204 can be adjusted.

[0026] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: During use, the bottom plate 1 is connected to the drone. A connecting plate 2 is installed at the bottom of the bottom plate 1, and the connecting plate 2 is connected to the bottom plate 1 through a telescopic cylinder 102. When the medicine storage cylinder 3 needs to be fixedly connected to the drone, first, the connecting plate 2 is docked with the top of the medicine storage cylinder 3. A restraint block 309 is installed at the top of the medicine storage cylinder 3, and the restraint block 309 cooperates with the second docking groove 202 at the top of the connecting plate 2. Since the restraint block 309 is triangularly arranged, when the connecting plate 2 moves downward, the restraint block 309 can be contracted so that it can successfully enter the second docking groove 202. After the restraint block 309 completely enters the second docking groove 202, it will reset. Because the restraint block 309 cooperates with the connecting plate 2, after the restraint block 309 enters the second docking groove 202, the connecting plate 2 will restrain the restraint block 309 to prevent it from falling off. A first docking groove 201 is opened at the bottom of the connecting plate 2, and the first docking groove 201 cooperates with the first docking block 304 at the top of the medicine storage cylinder 3. After the connecting plate 2 and the medicine storage cylinder 3 are completely fitted, the drone can be started. Since the medicine storage cylinder 3 has a certain weight, when the drone drives the bottom plate 1 to take off, it will not rise immediately. A telescopic cylinder 102 is installed between the bottom plate 1 and the connecting plate 2. The telescopic cylinder 102 is divided into a first sliding cylinder and a second sliding cylinder. A limiting groove is opened inside the first sliding cylinder, and a limiting block is opened on the surface of the second sliding cylinder. The limiting block cooperates with the limiting groove, so as to ensure that when the first sliding cylinder rises to a certain position, the second sliding cylinder can drive the medicine storage cylinder 3 to rise. A pulling rope 206 is installed at the bottom of the bottom plate 1. When the bottom plate 1 rises, it will drive the pulling rope 206 to move, and the other end of the pulling rope 206 is connected to a clamping block 204. Therefore, when the pulling rope 206 moves, the clamping block 204 will also move synchronously. A clamping groove 305 is opened on one side of the first docking block 304, and the clamping groove 305 cooperates with the clamping block 204. Therefore, as it moves, the clamping block 204 will enter the clamping groove 305 to achieve the purpose of restraining and fixing the medicine storage cylinder 3 to prevent it from falling off. Since the medicine storage cylinder 3 is connected to the drone through the first docking block 304 and the second docking block 307, a large amount of work can be saved during use, so that the efficiency of liquid medicine spraying can be higher.
