Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a sprayer. Background Technology
[0002] Sprayers are key equipment in modern agricultural and forestry plant protection operations. In particular, wind-driven sprayers, which use fans to generate high-speed airflow to deliver atomized pesticide solutions, play an important role in the prevention and control of pests and diseases in fields, orchards, and forests due to their advantages such as high operating efficiency, uniform droplets, and strong penetration.
[0003] In existing technologies, such sprayers typically include a walking mechanism, a pesticide tank, a power system, and a spraying system. Their power system often uses an internal combustion engine (such as a diesel or gasoline engine) as the sole power source for the entire machine. Specifically, the engine directly drives the fan impeller to rotate via a mechanical transmission mechanism to generate airflow, and simultaneously drives the liquid pump to pressurize the pesticide in the tank and deliver it to the nozzles for atomization.
[0004] However, the operation of high-power components in the machine, such as the fan and hydraulic pump, depends entirely on the mechanical energy output by the engine. This means that the engine power selection must meet the peak load requirements of the equipment. However, in most off-peak operating conditions in actual operation, the engine power is often in excess, resulting in poor fuel economy and high overall energy consumption. Utility Model Content

[0022] This utility model proposes a sprayer 1000.
[0023] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 In one embodiment of this utility model, the sprayer 1000 includes a walking mechanism 1, a chassis frame 2, a water tank 3, a fan spraying mechanism, a water pump 4, an engine 5, a generator 6, a battery box 7, and a control module 8 disposed on the chassis frame 2; the fan spraying mechanism includes a fan 9 and a nozzle 10; the water pump 4 is connected to the water tank 3 and the nozzle 10 through a pipeline; the generator 6, the water pump 4, and the fan 9 are all connected to the engine 5 in a transmission connection; the battery in the battery box 7 is electrically connected to the generator 6; the engine 5 and the walking mechanism 1 are both electrically connected to the control module 8.
[0024] The chassis frame 2, serving as the structural foundation and load-bearing platform of the entire machine, can be welded from high-strength steel, possessing excellent rigidity and load-bearing capacity, providing a stable mounting base for heavy components such as the water tank 3 and engine 5. The chassis frame 2 connects with the walking mechanism 1, forming the mobile body of the entire machine.
[0025] Water tank 3 is used to store liquid medicine. It is usually made of corrosion-resistant polyethylene or stainless steel, and its volume can be designed according to operational requirements.
[0026] The blower-driven spraying mechanism includes a blower 9, nozzles 10, and a protective shell 11. The protective shell 11 is typically made of metal sheet (such as galvanized steel sheet) or high-strength engineering plastic and is fixed to the front of the chassis frame 2, i.e., the end away from the water tank 3, by bolts or welding. The blower 9 is housed inside the protective shell 11, which isolates the high-speed rotating impeller of the blower 9 from the external environment. A protective mesh can be installed at the air inlet of the protective shell 11. Multiple nozzles 10 are provided and spaced circumferentially along the protective shell 11. The nozzles 10 can be either fan-shaped mist nozzles 10 or hollow cone mist nozzles 10, responsible for atomizing the high-pressure liquid pesticide.
[0027] The water pump 4 is preferably a plunger pump, which can provide a stable and high-pressure liquid output. The water pump 4 is connected to the bottom of the water tank 3 through an inlet pipe and to the nozzle 10 through an outlet pipe. When the water pump 4 is working, it pressurizes the liquid medicine in the water tank 3 and delivers it to the nozzle 10, atomizing it.
[0028] The output shaft of engine 5 is simultaneously connected to the input shafts of generator 6, water pump 4, and fan 9 via a multi-path transmission system (e.g., a combination of belts and pulleys, or a transfer case). This means that after engine 5 starts, it can simultaneously drive generator 6 to generate electricity, water pump 4 to pressurize, and fan 9 to generate airflow.
[0029] The generator 6 rotates and generates electricity under the drive of the engine 5. The generated electrical energy is mainly divided into two paths: one path is rectified and regulated, and then directly supplied to the electric components in the control module 8, the walking mechanism 1 and other vehicle electrical equipment; the other path is used to charge the battery in the battery box 7.
[0030] In the technical solution of this utility model, the engine 5 simultaneously drives the fan 9, the water pump 4 and the generator 6, converting a portion of the mechanical energy into electrical energy and storing it in the battery. This avoids the waste of excess power of the engine 5 under off-peak load and improves fuel economy.
[0031] Furthermore, in one embodiment of this utility model, please refer to... Figure 5The sprayer 1000 also includes a braking mechanism, which comprises an electric actuator 12, a clutch actuator 13, and a clutch 14. The electric actuator 12 is electrically connected to the control module 8, and the clutch actuator 13 connects the electric actuator 12 and the clutch 14. The clutch 14 controls the transmission connection between the water pump 4, the blower 9, and the engine 5. The control module 8 can send an electrical signal to the electric actuator 12. The electric actuator 12 then generates linear motion, which, through the transmission of the clutch actuator 13, drives the clutch 14 to quickly and reliably complete the engagement or disengagement action. For example, when spraying needs to be paused, the control module 8 commands the electric actuator 12 to extend, disengaging the clutch 14 via the clutch actuator 13, and the blower 9 and water pump 4 immediately stop. When operation needs to be resumed, the electric actuator 12 is commanded to retract, the clutch 14 engages, power is restored, and the blower 9 and water pump 4 quickly reach operating status. The braking mechanism also includes a Y-connector 15. The Y-connector 15 connects the electric actuator 12 and the clutch actuator 13.
[0032] Furthermore, in one embodiment of this utility model, please refer to... Figure 5 The sprayer 1000 also includes a servo motor 22. The servo motor 22 receives electrical signals from the control module 8 and transmits mechanical actions to the throttle mechanism of the engine 5 via the throttle cable, thereby adjusting the throttle opening and further regulating the engine 5's speed and power. The throttle cable is also equipped with a throttle cable clamp to maintain the cable at the appropriate tension and prevent loosening or misalignment. During maintenance or adjustment, a universal hammer can be used to adjust the tension of the throttle cable, ensuring coordinated operation of the servo motor 22 and the throttle system, and ensuring that the sprayer 1000 can operate efficiently and stably under different load conditions.
[0033] Specifically, in one embodiment of this utility model, please refer to... Figure 1 The sprayer 1000 also includes a housing 16, which is mounted on the traveling mechanism 1. The water pump 4, engine 5, and generator 6 are all housed within the housing 16. The housing 16 is typically made of sheet metal (such as corrosion-resistant aluminum or galvanized steel) or high-strength engineering plastics, balancing structural strength, lightweight design, and aesthetics. The housing 16 prevents large amounts of dust and dirt from entering the precision mating surfaces and cooling system of the water pump 4, engine 5, and generator 6, avoiding abnormal wear and blockages. It also provides some rain and moisture protection, protecting electrical components. Furthermore, it isolates corrosive pesticide droplets and vapors, protecting the surfaces of metal parts and preventing rust.
[0034] Furthermore, in one embodiment of this utility model, please refer to... Figure 1The sprayer 1000 also includes a navigation module, located on the top of the housing 16, and electrically connected to the control module 8. The navigation module includes a Beidou antenna 17 and a 4G cabinet antenna 18. The Beidou antenna 17 receives signals from the Beidou satellite navigation system, providing the sprayer 1000 with high-precision real-time positioning, speed, and heading information. The 4G cabinet antenna 18 connects to a mobile communication network for remote wireless data transmission. Operators can plan an electronic map of the work area and a route via a ground station or mobile terminal, and transmit this information to the control module 8 of the sprayer 1000 via the 4G network. The control module 8 compares the received high-precision real-time position information from the navigation module with the preset work path and generates control commands. It automatically adjusts the steering and speed of the walking mechanism 1, while simultaneously controlling the speed of the engine 5 and the braking mechanism of the fan 9, achieving fully automatic path-following, automatic start-stop spraying, and automatic turning maneuvers.
[0035] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 The housing 16 has maintenance windows 19 on both opposite sides. Each maintenance window 19 is equipped with an openable cover. The cover can be fixed to the housing 16 by screws, quick-release clips, or hinges, and can be opened when maintenance is required and closed during operation to maintain its protective function. The cover itself can also be a mesh structure, providing access while also allowing for ventilation and heat dissipation. The maintenance windows 19 are designed to facilitate maintenance by technicians.
[0036] Specifically, in one embodiment of this utility model, please refer to... Figure 6 and Figure 7 The traveling mechanism 1 includes a frame 101, tracks 102, drive wheels 103, a drive unit, and multiple support rollers 106. The drive wheels 103 and the multiple support rollers 106 are all mounted on the frame 101. The tracks 102 are fitted onto the drive wheels 103 and the multiple support rollers 106. The drive unit is located on the frame 101 and drives the drive wheels 103 to rotate. The drive unit is electrically connected to the control module 8. Two tracks 102 are installed on both sides of the frame 101. The drive unit, controlled by the control module 8, drives the traveling mechanism 1 to move. The tracked traveling mechanism 1, with its wide ground contact area, greatly reduces ground pressure, enabling the sprayer 1000 to easily handle complex terrains such as muddy, soft sandy soil, and rugged mountainous terrain where traditional wheeled equipment is prone to sinking or slipping, ensuring the continuity and timeliness of operations.
[0037] Furthermore, in one embodiment of this utility model, please refer to... Figure 6The drive unit includes a drive motor 104 and a reducer 105 mounted on the frame 101. The drive motor 104 is electrically connected to the control module 8, and its output shaft is connected to the input port of the reducer 105. The output shaft of the reducer 105 is connected to the drive wheel 103. The reducer 105 is fixedly mounted on the frame 101. The drive motor 104 is electrically connected to the control module 8 and directly receives speed and direction control signals from the control module 8. The input port of the reducer 105 is directly connected to the output shaft of the drive motor 104 via a key. The reducer 105 internally uses a gear set to achieve a certain reduction ratio. The output shaft of the reducer 105 directly drives the drive wheel 103 to rotate via a key connection or flange, etc.
[0038] Specifically, in one embodiment of this utility model, please refer to... Figure 1 An LED light 20 is provided at one end of the chassis frame 2 near the water tank 3. The LED light 20 is preferably a waterproof lighting lamp with high brightness, low power consumption and long life. Its installation position is usually located at the rear of the chassis, and the irradiation direction is towards the rear of the sprayer 1000.
[0039] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 The chassis frame 2 has a crash edge 21 near the water tank 3. The crash edge 21 is usually made of a highly elastic, wear-resistant polymer material (such as polyurethane or rubber) and is covered and fixed to the rear edge of the chassis frame 2 by a slot or fastener. As the first line of defense, the crash edge 21 can absorb the impact energy through its own deformation in the event of a minor collision, preventing the chassis frame 2 from directly colliding with obstacles (such as field ridges, tree trunks, and walls).
