Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery and equipment technology, and in particular to a pesticide spraying drone with a propeller-type mixing tank. Background Technology
[0002] Traditionally, pesticides are sprayed manually, which requires the user to carry the sprayer and spray the pesticide. During manual spraying, the pesticides themselves are toxic and can harm the human body. In addition, prolonged spraying can reduce the user's physical strength and reduce the efficiency of spraying. Now, in order to improve the efficiency of spraying, most areas have begun to use drones for pesticide spraying.
[0003] A propeller-type mixing tank for agricultural machinery drones, with publication number CN213735560U, includes a tank body. A fixed plate is provided inside the tank body, with its left and right ends fixedly connected to the side walls of the tank body. Several discharge ports are provided on the fixed plate. A first rotating rod is movably connected to the top of the tank body via bearings. The top of the first rotating rod extends through the fixed plate and the tank body, reaching the outside of the tank body, and is fixedly connected to a motor. This invention, through the coordinated use of the tank body, fixed plate, discharge ports, first rotating rod, mixing blades, motor, fixing device, first horizontal plate, first clamping rod, spring, discharge pipe, spraying box, nozzle, inlet, first movable door, second movable door, second rotating rod, crushing teeth, first bevel gear, second bevel gear, and anti-surge plate, can solve the problems of sedimentation leading to clogging of the spray pipe and nozzle, resulting in uneven spraying in existing technologies.
[0004] However, the mixing components in the aforementioned mixing tank have a relatively complex structure. During the mixing process, the mixing effect may not be high because the mixing blades only rotate in one direction to mix the medicine and water in the tank, which may easily lead to uneven mixing of the medicine and water. Utility Model Content
[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose an agricultural spraying drone with a propeller-type mixing tank.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A pesticide spraying drone with a propeller-type mixing tank includes a spray head fixedly connected to the body, a support rod fixedly connected to the bottom of the body, and further includes:
[0008] The mixing tank is fixedly connected to the machine body;
[0009] The drive rod is rotatably connected to the mixing tank.
[0010] The connecting rod is fixedly connected to the side wall of the drive rod.
[0011] The stirring blades are rotatably connected to the connecting rod.
[0012] A limiting rod is fixedly connected to the side wall of the mixing tank, and the limiting rod is located above the connecting rod;
[0013] An infusion tube is fixedly connected to the side wall of the mixing tank, and the end of the infusion tube away from the mixing tank is connected to the spray head.
[0014] Preferably, the limiting rod is an elastic rod.
[0015] Preferably, a stirring rod is fixedly connected to the bottom of the drive rod, and multiple sets of stirring rods are evenly distributed on the drive rod.
[0016] Preferably, a drive motor is fixedly connected to the top of the mixing box, and the drive end of the drive motor is fixedly connected to the drive rod.
[0017] Preferably, a feeding pipe is fixedly connected to the top of the mixing tank, and a sealing cap is threaded onto the feeding pipe.
[0018] Furthermore, an anti-slip pad is fixedly connected to the side wall of the sealing cover.
[0019] Compared with the prior art, this utility model provides a pesticide spraying drone with a propeller-type mixing tank, which has the following beneficial effects:
[0020] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model, through the mixing tank set on the machine body, can effectively mix the agent with water, thereby enabling the liquid to be sprayed evenly. Furthermore, through the stirring component set in the mixing tank, the materials in the mixing tank can be further stirred and agitated, thereby improving the mixing effect of the materials in the mixing tank. This effectively solves the problem in the prior art where insufficient mixing of agent and water can easily lead to the direct spraying of some agent, causing crops to be burned, thus reducing the possibility of damage to crops.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Example 1:
[0028] Reference Figures 1-4 A pesticide spraying drone with a propeller-type mixing tank includes a spray head 4 fixedly connected to the body 1, a support rod 101 fixedly connected to the bottom of the body 1, and further includes:
[0029] The mixing box 2 is fixedly connected to the body 1;
[0030] Drive rod 301 is rotatably connected to the mixing box 2;
[0031] Connecting rod 3011 is fixedly connected to the side wall of drive rod 301;
[0032] The stirring blade 5 is rotatably connected to the connecting rod 3011;
[0033] The limiting rod 202 is fixedly connected to the side wall of the mixing box 2, and the limiting rod 202 is located above the connecting rod 3011;
[0034] An infusion tube 401 is fixedly connected to the side wall of the mixing tank 2, and the end of the infusion tube 401 away from the mixing tank 2 is connected to the sprinkler head 4.
[0035] Limiting rod 202 is an elastic rod.
[0036] A stirring rod 3012 is fixedly connected to the bottom of the drive rod 301, and multiple sets of stirring rods 3012 are evenly distributed on the drive rod 301.
[0037] A drive motor 3 is fixedly connected to the top of the mixing box 2, and the drive end of the drive motor 3 is fixedly connected to the drive rod 301.
[0038] The top of the mixing tank 2 is fixedly connected to a feeding pipe 201, and a sealing cap 2011 is threaded onto the feeding pipe 201.
[0039] An anti-slip pad is fixedly connected to the side wall of the sealing cap 2011.
[0040] Reference Figure 3 With the anti-slip pad fixedly connected to the side wall of the sealing cover 2011, when the staff adds medicine to the mixing tank 2, it is not easy for the staff to slip when opening the sealing cover 2011.
[0041] Reference Figure 2 Before use, the staff opens the sealing cap 2011, pours water and medicine into the mixing tank 2, and then tightens the sealing cap 2011 onto the feeding pipe 201.
[0042] Reference Figures 1-4 When in use, start the machine body 1 and start the drive motor 3. The drive motor 3 will drive the drive rod 301 connected to its drive end to rotate. The rotation of the drive rod 301 will drive the stirring blade 5 connected to its bottom end to rotate. The rotation of the stirring blade 5 will stir the material in the mixing tank 2 in the horizontal direction, thereby making the medicine and water in the mixing tank 2 fully mixed.
[0043] During the stirring process of the stirring blade 5, after the stirring blade 5 rotates to a certain angle, the limiting rod 202 will abut against the upper end of the stirring blade 5. When the stirring blade 5 continues to rotate, the limiting rod 202 will push the stirring blade 5 to flip. At this time, the stirring blade 5 will rotate around the connecting rod 3011. At this time, the stirring blade 5 will disturb the material in the mixing box 2 in the vertical direction.
[0044] When the limiting rod 202 causes the stirring blade 5 to flip, the limiting rod 202 will also deform to a certain extent due to the compression of the stirring blade 5. When the stirring blade 5 flips, the stirring blade 5 will not abut against the limiting rod 202. At this time, the limiting rod 202 will vibrate and reset under its own elasticity. During the vibration and reset process of the limiting rod 202, the limiting rod 202 will further disturb the material in the mixture, thereby further ensuring the mixing effect of the material in the mixing tank 2.
[0045] It should be noted that the limiting rod 202 itself has a certain rigidity. When the limiting rod 202 is squeezed and vibrates, the limiting rod 202 will not affect the rotation of the stirring blade 5 due to excessive deformation.
[0046] This invention, through the mixing tank 2 installed on the machine body 1, can effectively mix the pesticide with water, thereby enabling the pesticide solution to be sprayed evenly. Furthermore, the stirring component installed in the mixing tank 2 can further stir and agitate the materials in the mixing tank 2, thereby improving the mixing effect of the materials in the mixing tank 2. This effectively solves the problem in the prior art where insufficient mixing of pesticide and water can easily lead to the direct spraying of some pesticide, causing crops to be burned, thus reducing the possibility of damage to crops.
[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
