Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation machinery technology, specifically to a tracked sprinkler truck driven by multiple complementary energy sources. Background Technology

[0002] Sprinkler irrigation, as a highly efficient and water-saving irrigation method, has been widely used in the cultivation of field crops, pasture, gardens, and cash crops. However, current mainstream sprinkler irrigation equipment in China still faces many challenges. In terms of energy drive, sprinkler irrigation equipment is mostly powered by a single diesel engine or the power grid. The former has high operating costs, significant noise and pollution, while the latter suffers from high uncertainty and poor flexibility. Regarding mobility and automation, most equipment relies on manual operation for starting, stopping, and moving, making it difficult to guarantee irrigation uniformity and accuracy. Especially in muddy or uneven fields, wheeled mobile equipment has poor mobility, affecting operational efficiency.

[0003] Therefore, there is a need in this field for a sprinkler irrigation system that can adapt to complex fields, has a flexible energy supply, and is highly automated. Utility Model Content

[0004] The purpose of this invention is to provide a tracked sprinkler irrigation vehicle driven by multiple complementary energy sources to solve the technical problems of existing sprinkler irrigation equipment, such as single power source, poor field passability, and insufficient level of automation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-energy complementary drive tracked sprinkler truck, including a body, a tracked walking mechanism, a navigation device, an oil-solar complementary drive device, a sprinkler device and an automatic control system.

[0006] The tracked walking mechanism is installed at the bottom of the vehicle body, providing good mobility for the sprinkler truck in muddy and uneven fields.

[0007] The navigation device includes an RTK locator mounted on the upper part of the vehicle body and a mechanical navigation mechanism set in the channel. The RTK locator provides high-precision absolute position information, while the mechanical navigation mechanism ensures that the vehicle body can move stably along one side of the channel through physical contact with the channel. The combination of the two navigation methods achieves low-cost and reliable path tracking.

[0008] The oil-solar hybrid drive system includes a photovoltaic panel, photovoltaic cells, and a diesel engine. The photovoltaic panel converts solar energy into electrical energy and stores it in the photovoltaic cells, while the diesel engine serves as a backup power source. Together, they form a hybrid power system that can flexibly switch power sources according to sunlight conditions and energy demand.

[0009] The sprinkler system includes a photovoltaic water pump, a photovoltaic motor, a diesel engine pump, and a high-flow spray gun. The photovoltaic water pump is driven by the photovoltaic motor, and the diesel engine pump is driven by the diesel engine. The two pump systems can work independently or in tandem, delivering water from the channel to the high-flow spray gun for irrigation via a water supply pipe.

[0010] The automatic control system is integrated into the control cabinet and is electrically connected to the oil-light complementary drive device, the sprinkler device and the navigation device, and is used to coordinate and control the movement of the whole vehicle, energy distribution and irrigation operations.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. Excellent mobility: The tracked chassis significantly improves the ability to move through wet, soft, and uneven fields, expanding the operating range; 2. Complementary energy sources and low operating costs: It combines solar and diesel energy. On sunny days, clean solar energy can be used first to reduce fuel consumption and operating costs, while diesel power is used on cloudy days or at night to ensure the continuity of operation. 3. Accurate and reliable navigation: The hybrid navigation method combining RTK and mechanical navigation not only ensures positioning accuracy, but also reduces the system's dependence on a single signal through physical guidance, thereby improving reliability; 4. High degree of automation: Through centralized control of the automatic control system, the sprinkler truck achieves automatic movement, energy management and precise irrigation, reducing manual intervention and improving operation efficiency; 5. Rational structure and high practicality: Two independent water pump systems provide redundancy and backup, improving equipment availability. The overall structure is compact and the functions are complete, making it very suitable for widespread use in large agricultural areas. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figure 1 and Figure 2 As shown, the present invention provides a multi-energy complementary drive tracked sprinkler truck, which mainly includes a vehicle body, a tracked walking mechanism 3, a navigation device, an oil-solar complementary drive device, a sprinkler device, and an automatic control system.

[0018] The vehicle body serves as the installation platform, with a tracked walking mechanism 3 mounted on its bottom, giving it excellent off-road performance. An RTK locator 4 and a control cabinet 1 are installed on the upper part of the vehicle body. A mechanical navigation mechanism 15 is installed within the irrigation channel 2 where the sprinkler truck operates; this mechanism can be a physical guiding device such as guide wheels or guide rails.

[0019] The photovoltaic-oil hybrid drive system includes photovoltaic panels 5 installed on the roof of the vehicle body, and photovoltaic cells 6, a diesel engine 9, and a battery 10 installed inside the vehicle body. The photovoltaic panels 5 convert solar energy into electrical energy, which is stored in the photovoltaic cells 6. The diesel engine 9 can both drive the diesel engine pump 11 and charge the battery 10.

[0020] The sprinkler system includes two water pumping systems. One is a photovoltaic water pump 7 driven by a photovoltaic motor 8, and the other is a diesel pump 11 driven by a diesel engine 9. The inlet of both pumps extends into the channel 2 through a suction pipe 14, and the outlet is connected to a high-flow spray gun 12 installed at the front or top of the vehicle body through a water supply pipe 13.

[0021] The automatic control system is integrated into control cabinet 1, which contains motion control module and irrigation management module (not shown in the figure). The system is electrically connected to actuators such as RTK positioner 4, photovoltaic motor 8, diesel engine 9, and diesel pump 11 via cables. It receives navigation signals and controls the vehicle's movement, the start and stop of the water pump, and the distribution of energy, thereby realizing automated irrigation operations.

[0022] Figure 3 A flowchart of the irrigation control process for the oil-solar hybrid drive device and sprinkler irrigation device of this utility model is provided. The working process is as follows: When the sprinkler truck is operating in the field, the operator sets the operating parameters through the control cabinet. The vehicle moves under the drive of the track 3. The RTK positioner 4 and the mechanical navigation mechanism 15 in the channel 2 work together to ensure that the vehicle moves accurately along the channel. The automatic control system prioritizes starting the photovoltaic water pump 7 according to the energy status (such as light intensity and battery power). If the photovoltaic power is insufficient, the diesel pump 11 is automatically started. Water is pumped from the channel 2 through the suction pipe 14 and sent to the high-flow spray gun 12 through the water supply pipe 13, and evenly sprayed onto the farmland.

[0023] This utility model discloses a multi-energy complementary driven tracked sprinkler truck that, through an automatic control system, can achieve intelligent energy management, automatic obstacle avoidance, cloud data synchronization, and fully automated operation, thereby improving irrigation efficiency and energy utilization.

[0024] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
