Description
Technical Field
[0001] This utility model relates to the field of terminal equipment technology, specifically to a handheld terminal device for farmland data collection. Background Technology
[0002] In modern agricultural production, handheld data collection terminals play a crucial role. These portable devices, specifically designed for agriculture, can collect various data from farmland in real time, such as soil moisture, temperature, nutrient content, and crop growth status. These devices offer numerous advantages and benefits. They significantly improve the efficiency and accuracy of farmland data collection, enabling agricultural producers to understand the actual conditions of their fields and make informed decisions. This helps improve crop yield and quality, reduce production costs, and promote sustainable agricultural development. Furthermore, their portability allows operators to move freely in the fields, collecting data anytime, anywhere, without being limited by geographical location or environment.
[0003] Existing handheld data acquisition terminals for farmland typically possess basic data acquisition functions and simple mechanical structures. They generally include a main unit for data processing and storage, and various connected sensors for collecting different types of data. In terms of workflow, operators move the handheld device across the farmland, initiating the data acquisition process via buttons or a touchscreen. The sensors transmit the collected data to the main unit for processing and storage, and then the data can be transmitted to a backend system for further analysis and application via wired or wireless connections.
[0004] These types of terminals typically operate for extended periods in farmland environments, which are characterized by high levels of dust, silt, and other particulate matter, and relatively complex operating conditions. Existing handheld data acquisition terminals for farmland generally incorporate ventilation holes on their casings to dissipate heat from internal electronic components. However, these ventilation holes are usually fixed structures, lacking easy-to-clean designs. Over long-term use, dust, silt, and other particulate matter in the air easily adhere to the openings and walls of these ventilation holes, gradually causing blockage and affecting the terminal's heat dissipation performance. When heat dissipation performance deteriorates, internal components are prone to overheating and operational instability. Current technologies often require external tools or even disassembly of the terminal to clean these ventilation holes, which is inconvenient and difficult to perform quickly on-site. Therefore, improving the cleanability of the ventilation holes without affecting the normal operation of the terminal has become a pressing technical problem to be solved in this field.

[0034] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0035] Please see Figures 1 to 5A handheld terminal device for collecting farmland data includes a terminal housing 1. The terminal housing 1 is provided with a display screen 2, control buttons 3, a charging port 4, and multiple heat dissipation holes 12 for heat dissipation. The control buttons 3 are provided with protective pads 22, and the bottom of the protective pads 22 is fixedly connected to the top of the terminal housing 1.
[0036] The heat dissipation hole 12 is provided with a cleaning assembly for cleaning the heat dissipation hole 12. The cleaning assembly includes a cleaning plate 9 disposed on the outside of the heat dissipation hole 12 and movable relative to the terminal housing 1, and a slider 6 for driving the cleaning plate 9 to move relative to the heat dissipation hole 12.
[0037] The cleaning plate 9, driven by the slider 6, scrapes and cleans the heat dissipation holes 12. A push plate 8 is also fixedly connected to the outer side of the cleaning plate 9. The push plate 8 is made of sturdy yet lightweight aluminum alloy with an anti-slip surface for easy operation. The main body of the cleaning plate 9 is made of soft but resilient rubber material, with fine bristles distributed on its surface, effectively cleaning dust adhering to the outer wall of the heat dissipation holes 12.
[0038] A limiting post 5 is provided inside the terminal housing 1, and the slider 6 is slidably mounted on the limiting post 5. A spring 7 is sleeved on the limiting post 5, and the two ends of the spring 7 are fixedly connected to the slider 6 and the inner wall of the terminal housing 1, respectively. The limiting post 5 is made of stainless steel, with a smooth surface and high hardness, which can provide stable guidance for the movement of the slider 6.
[0039] The terminal housing 1 is also provided with a cleaning component limiting device. The cleaning component limiting device includes a ball-locking component 14 slidably disposed inside the terminal housing 1, and a second spring 13 sleeved on the outside of the ball-locking component 14. The two ends of the second spring 13 are respectively fixedly connected to the ball head end of the ball-locking component 14 and the inner wall of the terminal housing 1. The cleaning plate 9 is provided with a groove corresponding to the ball head end of the ball-locking component 14.
[0040] Specifically, when cleaning the heat dissipation hole 12 is required, the push plate 8 is pulled, and the ball head of the ball clamping assembly 14 disengages from the groove on the cleaning plate 9, thereby causing the cleaning plate 9 connected to it to move smoothly on the outer wall of the heat dissipation hole 12. This can prevent dust in the air from gradually accumulating during equipment operation and clogging the inner wall of the heat dissipation hole 12, thus ensuring that the equipment can dissipate heat normally and maintain the normal operating condition of the equipment. During the movement of the cleaning plate 9, the slider 6 will slide on the outer wall of the limit post 5. When the slider 6 slides, it will cause the spring 7 to be compressed. When cleaning is completed, the rebound force of the spring 7 will push the cleaning plate 9 to reset. At this time, the spring 13 will push the ball clamping assembly 14 to lock in the groove on the inner wall of the cleaning plate 9, which can effectively fix the position of the cleaning plate 9, prepare for the next cleaning operation, and also ensure the stability of the cleaning plate 9 during equipment operation.
[0041] This farmland data collection handheld terminal device also includes a fixing component; the fixing component is used for users to fix the device in place when holding it.
[0042] The fixing assembly includes a first connecting strap 10 and a second connecting strap 11, which are respectively fixedly connected to both sides of the terminal housing 1. Both the first connecting strap 10 and the second connecting strap 11 are made of high-strength nylon material, which has good wear resistance and flexibility, ensuring that it is not easily damaged during long-term use.
[0043] A connecting frame 15 is fixedly connected to the connecting strip 10. Multiple sliding posts are provided on the connecting frame 15. Springs 20 are sleeved on the sliding posts. The two ends of the springs 20 are fixedly connected to the inner wall of the connecting frame 15 and the bottom surface of the connecting plate 18, respectively. Multiple fixing teeth 17 are provided on the top surface of the connecting plate 18.
[0044] Multiple fixing strips 16 are provided on the outer wall of the second connecting strip 11. The second connecting strip 11 is inserted into the inside of the connecting frame 15 and the fixing strips 16 are engaged with the fixing teeth 17.
[0045] A fixed frame 21 is slidably connected to the outer wall of the connecting strip 10 to limit the end of the connecting strip 11.
[0046] Both ends of the connecting plate 18 penetrate the side wall of the connecting frame 15 and are fixedly connected to the control plate 19. The control plate 19 is a plastic plate with a frosted surface, which not only increases the friction between the hand and the control plate 19 to prevent slippage during pressing, but also the plastic material is lightweight and low cost.
[0047] Specifically, during the use of the equipment, the operator first moves their palm to the inner wall of connecting belt 10 and connecting belt 2 11, and then presses down on the control plate 19. When the control plate 19 is pressed, the connecting plate 18 drives the fixing teeth 17 to move downward and separate from the fixing strip 16. During the movement of the connecting plate 18, it slides on the inner wall of the connecting frame 15. The inner wall of the connecting frame 15 limits the sliding of the connecting plate 18, ensuring that the connecting plate 18 moves along the expected trajectory and avoiding deviation or jamming. Furthermore, when the connecting plate 18 slides, it drives the spring 3 20 to compress. The inner wall structure of the connecting frame 15 and the sliding column can also limit the spring 3 20, preventing... During compression and rebound, the spring twists or misaligns to ensure its normal operation. After the fixing tooth 17 separates from the fixing strip 16, the operator can pull the connecting belt 2 11. At this time, the connecting belt 1 10 and the connecting belt 2 11 will press and fix the palm area. In this way, the equipment can fit better with the palm, enhance the stability of the equipment during use, and reduce the impact of palm shaking or displacement on operation. Then, the operator releases the downward pressure of the control plate 19 and uses the rebound force of the spring 3 20 to push the fixing tooth 17 to engage with the fixing strip 16, thereby fixing the position of the connecting belt 2 11 again, effectively improving the convenience and stability of the equipment.
[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
