Description

Technical Field

[0001] This utility model relates to the field of plant protection machine technology, specifically a self-propelled multi-functional plant protection machine. Background Technology

[0002] In modern agricultural production, agricultural drones have been widely used in the field of plant protection operations due to their advantages of high efficiency, precision, and flexibility. They can quickly and over large areas complete tasks such as pesticide spraying and seed sowing, effectively improving agricultural production efficiency and reducing labor costs.

[0003] However, existing agricultural drones still face several problems in practical use. When moving short distances on the ground, traditional agricultural drones typically require manual handling, which not only increases the workload of operators but also easily damages the drone during transport. Furthermore, manual handling is inefficient when adjusting the drone's position or relocating the work area, failing to meet the demands of rapid operation. Additionally, pesticide solutions are prone to sedimentation and stratification, resulting in uneven concentrations. This directly affects the effectiveness of agricultural operations; for example, during pesticide spraying, uneven concentrations may leave some crops unprotected while others suffer phytotoxicity due to excessively high concentrations.

[0004] In conclusion, developing a self-propelled, multi-functional agricultural drone that can move easily over short distances on the ground and has the function of mixing pesticide solutions has significant practical significance and application value. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, this utility model provides a self-propelled multi-functional plant protection machine, including a plant protection machine body 1. A pesticide tank 2 is located at the bottom of the plant protection machine body 1. A drive wheel structure 3 is located on one side of the bottom of the plant protection machine body 1. Electric steering wheels 4 are fixedly connected to the front and rear sides of the other side of the bottom of the plant protection machine body 1 via brackets, and the two electric steering wheels 4 are electrically connected via a synchronizer. A drive motor 5 located above the drive wheel structure 3 is fixedly connected to one side of the bottom of the plant protection machine body 1 via a connecting frame. A worm gear 6 is fixedly connected to the output end of the drive motor 5. A worm wheel 7 is fixedly connected to the surface of the drive wheel structure 3. The surface of the worm gear 6 meshes with the surface of the worm wheel 7. The worm gear 6 and the worm wheel... The surface of 7 is covered with a protective shell. The top of the protective shell is fixedly connected to the bottom of the plant protection machine body 1 by bolts. The inside of the protective shell is filled with grease. The end of the worm gear 6 away from the drive motor 5 is fixedly connected to a stirring rod 8. The end of the stirring rod 8 away from the worm gear 6 passes through the inside of the liquid tank 2 and is rotatably connected to its inner wall. Several evenly distributed stirring blades are fixedly connected to the surface of the stirring rod 8. A spraying structure 9 is provided on one side of the bottom of the plant protection machine body 1. Heating structures 10 are provided on both the front and rear sides of the liquid tank 2. A control system is provided inside the plant protection machine body 1. The electric steering wheel 4, drive motor 5, spraying structure 9 and heating structure 10 are all electrically connected to the control system.

[0018] refer to Figure 1 The drive wheel structure 3 includes two axle frames 11 fixed on the front and rear sides of the bottom of the plant protection machine body 1, and the two axle frames 11 are symmetrically arranged. The drive shaft 12 is rotatably connected to the inside of the axle frame 11 through bearings. The surface of the drive shaft 12 is fixedly connected to the inner wall of the worm gear 7. The front and rear ends of the drive shaft 12 are fixedly connected to the self-propelled wheel hub 13, and the surface of the self-propelled wheel hub 13 is equipped with rubber tires.

[0019] As a technical optimization of this utility model, the axle frame 11 provides stable support for the transmission shaft 12, ensuring the stability and reliability of the transmission. The transmission shaft 12 rotates within the axle frame 11 through bearings, reducing frictional resistance and making power transmission smoother. The combination of the self-propelled wheel hub 13 and rubber tires enhances the friction between the plant protection machine and the ground, improving walking stability and grip, ensuring smooth driving under different terrain conditions. On the other hand, the rubber tires have a certain elasticity, which can effectively buffer the bumps and vibrations of the ground, protect the internal structure of the plant protection machine, and extend its service life.

[0020] refer to Figure 1 The spraying structure 9 includes a nozzle row 14 fixedly connected to one side of the bottom of the plant protection machine body 1. The input end of the nozzle row 14 is connected to a booster pump 15, and the input end of the booster pump 15 is connected to one side of the liquid tank 2.

[0021] As a technical optimization of this utility model, the setting of the nozzle row 14 enables the pesticide solution to be sprayed evenly on the crops, thereby improving the coverage area and spraying effect of the pesticide. The function of the booster pump 15 is to increase the pressure of the pesticide solution, so that the pesticide solution can be discharged from the nozzle row 14 at an appropriate speed and pressure, ensuring that the pesticide solution can effectively reach the target position, improving the utilization rate of pesticides, reducing pesticide waste, and ensuring good spraying effect under different operating environments, thus improving the quality of plant protection operations.

[0022] refer to Figure 4 The heating structure 10 includes an installation groove that is formed on the surface of the liquid tank 2 and extends through the inside and outside. A heat-conducting plate 16 is fixedly connected to the inside of the installation groove by a waterproof and heat-insulating sealant. The surface of the heat-conducting plate 16 is provided with an anti-rust coating. An insulation cover 17 is fixedly connected to the surface of the liquid tank 2. An electric heating plate 18 is fixedly connected to the inside of the insulation cover 17. The surface of the electric heating plate 18 is attached to the surface of the heat-conducting plate 16. A temperature sensor that is electrically connected to the electric heating plate 18 is installed inside the liquid tank 2. The temperature sensor is also electrically connected to the control system built into the plant protection machine body 1.

[0023] As a technical optimization of this utility model, the heat-conducting plate 16 in the installation groove is fixed with waterproof and heat-insulating sealant, which not only ensures good thermal conductivity but also prevents pesticide leakage and heat loss, thus improving energy utilization efficiency. The anti-rust coating extends the service life of the heat-conducting plate 16 and reduces maintenance costs. The combination of the heat insulation cover 17 and the electric heating plate 18 can heat the pesticide solution in the pesticide tank 2, ensuring that the solution maintains good fluidity and activity at a suitable temperature. Especially in cold weather conditions, it can effectively prevent the solution from solidifying or degrading, ensuring the normal operation of plant protection. The cooperation of the temperature sensor and control system enables real-time monitoring and precise control of the pesticide solution temperature, further improving the stability and reliability of the operation.

[0024] refer to Figure 1 A water level observation tank 19 is provided on one side of the medicine tank 2, and a transparent glass is fixedly connected inside the water level observation tank 19 by sealant.

[0025] As a technical optimization of this utility model, by setting up a water level observation tank 19 and transparent glass, the operator can intuitively observe the water level in the pesticide tank 2 through the transparent glass, and promptly understand the remaining amount of pesticide solution so as to prepare for replenishment in advance, avoid interruption of operation due to insufficient pesticide solution, improve the continuity and efficiency of operation, and at the same time facilitate the daily inspection and maintenance of the pesticide tank 2, help to discover potential problems in time, and ensure the normal operation of the plant protection machine.

[0026] refer to Figure 1 The top of the liquid tank 2 is connected to a water injection pipe 20, and the top of the water injection pipe 20 extends through to the top of the plant protection machine body 1 and is threaded with a sealing pipe cap.

[0027] As a technical optimization of this utility model, the water injection pipe 20 and the sealing cap facilitate the injection of pesticide solution into the pesticide tank 2, and the top extends to the top of the plant protection machine body 1, making it convenient for operators to operate. The threaded connection of the sealing cap ensures the airtightness of the pesticide tank 2, preventing pesticide leakage and evaporation, and guaranteeing the quality and safety of the pesticide solution. At the same time, the sealing cap also prevents dust, debris, etc. from entering the pesticide tank 2, avoiding contamination of the pesticide solution, and further improving the effectiveness and quality of plant protection operations.

[0028] The working principle and usage process of this utility model are as follows: Before use, the operator first opens the sealed cap at the top of the water injection pipe 20 and injects an appropriate amount of pesticide solution into the pesticide tank 2 through the water injection pipe 20. The water level can be observed through the transparent glass in the water level observation tank 19. When it is necessary to move the main body 1 of the plant protection machine over a short distance, the control system can be started, and the drive motor 5 starts to work. Its output end drives the worm gear 6 to rotate. Since the worm gear 6 meshes with the worm wheel 7 on the drive wheel structure 3, the transmission shaft 12 rotates, driving the self-propelled wheel hub 13 and the rubber tires to rotate, realizing the autonomous walking of the plant protection machine; the two electric steering wheels 4 are electrically connected through a synchronizer and can be flexibly steered under the control of the control system, enabling the plant protection machine to move along a preset route. Simultaneously, when the drive motor 5 is working, the stirring rod 8 connected to the end of the worm gear 6 away from the drive motor 5 rotates accordingly. The stirring blades stir the liquid in the liquid tank 2 to prevent sedimentation and stratification, ensuring uniform liquid concentration. It can also allow the main body 1 of the plant protection drone to lift and hover, and start the drive motor 5 to continuously stir the liquid (the main body 1 of the plant protection drone is a common plant protection drone, which is a mature technology, so its working principle will not be described in detail). When spraying is required, the control system starts the booster pump 15 to pressurize the liquid in the liquid tank 2 and deliver it to the nozzle row 14 for even spraying on the crops. During spraying, the drive motor 5 can be selected to stir the liquid according to the characteristics of the liquid. In cold weather, in order to ensure the fluidity and activity of the liquid, the control system controls the electric heating plate 18 to work based on the liquid temperature information fed back by the temperature sensor. The heat generated by the electric heating plate 18 is transferred to the liquid in the liquid tank 2 through the heat conduction plate 16, and the heat insulation cover 17 can reduce heat loss.
