Description

Technical Field

[0001] This invention relates to the field of farmland data acquisition technology, specifically to a farmland environment and engineering data acquisition vehicle. Background Art

[0002] High summer temperatures can significantly raise farmland temperatures beyond the optimal range for crop growth. This can inhibit the activity of key enzymes in photosynthesis, reducing photosynthetic efficiency. At the same time, it can accelerate respiration, consuming more nutrients and leading to slow crop growth and insufficient dry matter accumulation. High temperatures can also disrupt the crop's water balance, exacerbating transpiration and causing plants to wilt due to water loss. Reduced root water absorption capacity can also lead to drought stress. Furthermore, high temperatures can cause abnormal flowering and fruiting in crops, such as degeneration of rice spikelets, abortion of corn tassels, and flower and fruit drop in vegetables. It can also trigger the proliferation of pests and diseases, reducing crop yield and quality. Extreme high temperatures can even cause crops to die directly. Current methods for monitoring farmland temperature mostly involve installing thermometers on field ridges. However, water temperatures vary in different areas, and fixed installations are difficult to cover complex farmland terrains. Special areas such as low-lying areas and slopes are prone to creating monitoring blind spots, making it difficult to reflect the spatial heterogeneity of water temperature. At the same time, fixed equipment is exposed to the field for a long time and is susceptible to the effects of wind, rain, crop obstruction, and soil subsidence, which can lead to sensor displacement or damage and poor data acquisition stability. Therefore, we propose a farmland environment and engineering data acquisition vehicle. Summary of the Invention

[0003] I. Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a farmland environment and engineering data acquisition vehicle. It solves the problem that most existing farmland temperature acquisition methods rely on installing thermometers on field ridges for monitoring. However, water temperatures vary in different areas, and fixed installations are difficult to cover complex farmland terrains, such as low-lying areas and slopes, which can easily create monitoring blind spots and fail to reflect the spatial heterogeneity of water temperature. At the same time, fixed equipment is exposed to the field for a long time and is susceptible to the effects of wind, rain, crop obstruction, and soil subsidence, which can lead to sensor misalignment or damage and poor data acquisition stability.

[0004] II. Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a farmland environment and engineering data acquisition vehicle, comprising a vehicle body, wheels, and a temperature measuring device. The wheels are rotatably connected to both ends of the vehicle body. The temperature measuring device is disposed on the upper surface of the vehicle body and includes a rectangular sleeve fixedly connected to the vehicle body. A bracket is slidably connected to the upper surface of the rectangular sleeve, and a crossbar is slidably connected to the inner wall of the bracket. A frame is fixedly connected to the upper surface of the crossbar, and a traction line is fixedly connected to the lower surface of the frame. A support plate is fixedly connected to the end of the traction line away from the frame. A barrier is fixedly connected to the upper surface of the support plate, and a water storage tank is fitted inside the inner wall of the barrier. A lead screw is fixedly connected to the lower surface of the water storage tank. A through hole is formed on the surface of the support plate, and the lead screw is inserted into the through hole on the surface of the support plate. A retaining ring is threaded onto the surface of the lead screw. A slide rail is fixedly connected to the inner wall of the water tank, and a thermometer is slidably connected to the inner wall of the slide rail. A locking tooth is provided on one side of the thermometer. A fixing sleeve is fixedly connected to one end of the water tank, and a first motor is fixedly connected to the inner wall of the fixing sleeve. A gear is fixedly connected to the drive end of the first motor, and the gear meshes with the locking tooth on one side of the thermometer. By setting up a temperature measuring device, the water temperature of the paddy field can be simulated and monitored by simulating the silt and water environment of the paddy field in the water tank. With the help of the first motor driving the gear to move the thermometer up and down, the temperature change at different water levels can be accurately monitored. At the same time, by pulling the frame upward and the traction line to raise the tray, the environment of the paddy field at a high slope can be simulated. The position of the crossbar is fixed by the threaded rod to ensure the stability of the simulation state, so as to comprehensively and flexibly obtain paddy field water temperature data under different locations and water levels, and meet diverse measurement needs.

[0005] Preferably, the upper surface of the bracket is provided with a threaded hole, and a threaded rod is threadedly connected to the upper surface of the bracket. By setting the threaded rod, after the frame is pulled upward and the support plate is raised through the traction line, the overall height of the water storage tank is raised to simulate the environment of a paddy field at a high slope. Then, the threaded rod is rotated to insert it into the corresponding adjustment hole, thereby fixing the position of the crossbar.

[0006] Preferably, the surface of the crossbar is provided with adjustment holes, and there are multiple adjustment holes on the surface of the crossbar. The threaded rod is inserted into the adjustment holes on the surface of the crossbar.

[0007] Preferably, a pulley is rotatably connected to the lower surface of the crossbar, and movable grooves are provided at both ends of the bracket. The pulley is located in the movable groove, and a partition is fixedly connected to both ends of the pulley.

[0008] Preferably, there are four supports, which are arranged symmetrically.

[0009] Preferably, the surface of the vehicle body is provided with a shock-absorbing device, which includes an arc-shaped sleeve fixedly connected to the vehicle body. A bending rod is slidably connected to the inner wall of the arc-shaped sleeve, and the end of the bending rod away from the arc-shaped sleeve is fixedly connected to a support plate. A damper is fixedly connected to the lower surface of the bending rod. By setting up the shock-absorbing device, when the vehicle body moves and shakes, the bending rod, in conjunction with the damper, compresses the pressure spring. The elastic force generated by the pressure spring can effectively buffer the vibration. Combined with the tension of the traction rope, the water tank is kept stable, reducing violent fluctuations of water and silt in the water tank caused by shaking, preventing interference with temperature detection, ensuring the accuracy and reliability of temperature measurement data, and providing a precise basis for subsequent data analysis.

[0010] Preferably, a pressure spring is fixedly connected to the inner wall of the arc-shaped sleeve. The end of the pressure spring away from the arc-shaped sleeve is fixedly connected to the damper. By setting the pressure spring, when the vehicle body moves and sways, the bending rod and the damper will compress it. At this time, the pressure spring will generate a reverse elastic force due to deformation. This elastic force can effectively offset and reduce the impact force transmitted to the water tank by the vehicle body sway, reduce the vibration amplitude of the water tank, and further maintain the stability of the water tank with the help of the traction rope.

[0011] Preferably, a shock-absorbing device is provided at one end of the vehicle body. The shock-absorbing device includes an interface located at one end of the water storage tank. A connecting pipe is threaded onto the surface of the interface. A flexible hose is fixedly connected to one end of the connecting pipe, and a filter cartridge is fixedly connected to the end of the flexible hose away from the connecting pipe. By setting up the shock-absorbing device, when the vehicle body moves and shakes, the bending rod works in conjunction with the damping compression spring. The elastic force generated by the compression spring can effectively buffer the vibration. Combined with the tension of the traction rope, the water storage tank is kept stable, reducing violent fluctuations of water and silt in the water storage tank caused by shaking. This prevents interference with temperature detection, ensures the accuracy and reliability of temperature measurement data, and provides a precise basis for subsequent data analysis.

[0012] Preferably, a suction device is provided at one end of the vehicle body. The suction device includes a retaining ring, which is fixedly connected to the vehicle body. A second motor is fixedly connected to the surface of the retaining ring. By setting the second motor, the rotation drives the jacket, which in turn drives the hose to flip, so that the filter cartridge can be immersed in the paddy field water. This allows the water pump to draw paddy field water to replenish the water storage tank. After replenishment, the second motor drives the jacket again to bend the hose upward, reducing the drag of the hose and affecting the movement of the vehicle body.

[0013] Preferably, the drive end of the second motor is fixedly connected to a jacket, the jacket is sleeved with a hose, a water pump is fixedly connected to the surface of the hose, the inlet end of the water pump is connected to the hose, and the outlet end of the water pump is connected to a connecting pipe. By setting up a water pump, when the water in the storage tank evaporates due to long-term monitoring, the water in the paddy field is pumped to replenish the storage tank. Specifically, when water needs to be replenished, after the water pump is started, the water collected by the filter cartridge immersed in the paddy field water can be pumped into the storage tank through the hose, thereby maintaining the stability of the water level in the storage tank.

[0014] In summary, the technical effects and advantages of this invention are as follows: 1. In this invention, by setting up a temperature measuring device, the water temperature of paddy fields can be simulated and monitored by simulating the silt and water environment of paddy fields in a water storage tank. The temperature measuring device can be accurately monitored by driving the gear of the first motor to slide up and down. At the same time, by pulling the frame upward and the traction line to raise the tray, the paddy field environment at the top of the slope can be simulated. The position of the crossbar is fixed by the threaded rod to ensure the stability of the simulation state. Thus, paddy field water temperature data under different locations and water levels can be obtained comprehensively and flexibly to meet diverse measurement needs.

[0015] 2. In this invention, by setting up a shock absorption device, when the vehicle body moves and causes shaking, the bending rod is used in conjunction with the damping compression spring. The elastic force generated by the compression spring can effectively buffer the vibration. Combined with the tension of the traction rope, the water tank is kept stable, reducing the violent fluctuation of water and silt in the water tank caused by shaking, preventing interference with temperature detection, ensuring the accuracy and reliability of temperature measurement data, and providing a precise basis for subsequent data analysis.

[0016] 3. In this invention, by setting up a suction device, when the water in the storage tank evaporates due to long-term detection, the vehicle can be driven to the paddy field. The second motor drives the jacket to flip the hose, allowing the filter cartridge to be immersed in the paddy field water. Then, the water pump draws water from the paddy field to replenish the storage tank, maintaining a stable water level in the storage tank and ensuring the realism of the simulated environment. After replenishment, the second motor drives the jacket to bend the hose upwards, reducing the drag of the hose and affecting the movement of the vehicle, making it easier for the equipment to move to the next measurement point, thus improving the continuous working capacity and measurement efficiency of the equipment.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] refer to Figures 1-8The illustrated farmland environment and engineering data acquisition vehicle includes a vehicle body 1, wheels 2, and a temperature measuring device 3. The wheels 2 are rotatably connected to both ends of the vehicle body 1. The temperature measuring device 3 is mounted on the upper surface of the vehicle body 1 and includes a rectangular sleeve 33, which is fixedly connected to the vehicle body 1. A bracket 34 is slidably connected to the upper surface of the rectangular sleeve 33, and a crossbar 35 is slidably connected to the inner wall of the bracket 34. A frame 32 is fixedly connected to the upper surface of the crossbar 35, and the lower surface of the frame 32 is fixedly connected to... A traction line 36 is connected, and a support plate 37 is fixedly connected to the end of the traction line 36 away from the frame 32. A retaining wall 318 is fixedly connected to the upper surface of the support plate 37, and a water storage tank 31 is fitted inside the inner wall of the retaining wall 318. A lead screw 38 is fixedly connected to the lower surface of the water storage tank 31. A through hole is opened on the surface of the support plate 37, and the lead screw 38 is inserted into the through hole on the surface of the support plate 37. A retaining ring 39 is threaded onto the surface of the lead screw 38. A slide rail 312 is fixedly connected to the inner wall of the water storage tank 31. A thermometer 313 is slidably connected to the inner wall of the water tank 31. A retaining tooth is provided on one side of the thermometer 313. A fixing sleeve 316 is fixedly connected to one end of the water tank 31. A first motor 314 is fixedly connected to the inner wall of the fixing sleeve 316. A gear 315 is fixedly connected to the drive end of the first motor 314. The gear 315 meshes with the retaining tooth on one side of the thermometer 313. By setting the temperature measuring device 3, the water temperature of the paddy field can be simulated and monitored by simulating the silt and water environment of the paddy field in the water tank 31. With the help of the first motor 314 driving the gear 315 to drive the thermometer 313 to slide up and down, the temperature change of different water levels can be accurately monitored. At the same time, by pulling the frame 32 and the traction line 36 upward, the support plate 37 can be raised to simulate the paddy field environment at the top of the slope. The position of the crossbar 35 is fixed by the threaded rod 317 to ensure the stability of the simulation state. Thus, the paddy field water temperature data under different positions and water levels can be obtained comprehensively and flexibly to meet diverse measurement needs.

[0021] The upper surface of the bracket 34 is provided with a threaded hole, and a threaded rod 317 is threadedly connected to the upper surface of the bracket 34. By setting the threaded rod 317, the frame 32 is pulled upward and the support plate 37 is raised through the traction line 36, so that the overall height of the water tank 31 is raised to simulate the rice field environment at the top of the slope. Then, by rotating the threaded rod 317, it is inserted into the corresponding adjustment hole, thereby fixing the position of the crossbar 35.

[0022] The crossbar 35 has multiple adjustment holes on its surface, and the threaded rod 317 is inserted into the adjustment holes on the surface of the crossbar 35.

[0023] Among them, the lower surface of the crossbar 35 is rotatably connected to the pulley 311, the two ends of the bracket 34 are provided with moving grooves, the pulley 311 is located in the moving groove, and the two ends of the pulley 311 are fixedly connected to the partition plate 310.

[0024] There are four brackets 34, which are arranged symmetrically.

[0025] The surface of the vehicle body 1 is equipped with a shock-absorbing device 4, which includes an arc-shaped sleeve 42. The arc-shaped sleeve 42 is fixedly connected to the vehicle body 1. A bent rod 41 is slidably connected to the inner wall of the arc-shaped sleeve 42. The end of the bent rod 41 away from the arc-shaped sleeve 42 is fixedly connected to the support plate 37. A damper 43 is fixedly connected to the lower surface of the bent rod 41. By setting up the shock-absorbing device 4, when the vehicle body 1 moves and shakes, the bent rod 41 and the damper 43 are used to compress the pressure spring 44. The elastic force generated by the pressure spring 44 can effectively buffer the vibration. Combined with the tension of the traction rope, the water tank 31 is kept stable, reducing the violent fluctuation of water and silt in the water tank 31 caused by shaking, preventing interference with temperature detection, ensuring the accuracy and reliability of temperature measurement data, and providing a precise basis for subsequent data analysis.

[0026] Among them, a pressure spring 44 is fixedly connected to the inner wall of the arc sleeve 42. The end of the pressure spring 44 away from the arc sleeve 42 is fixedly connected to the damper 43. By setting the pressure spring 44, when the vehicle body 1 moves and shakes, the bending rod 41 and the damper 43 will compress it. At this time, the pressure spring 44 will generate a reverse elastic force due to deformation. This elastic force can effectively offset and reduce the impact force transmitted from the shaking of the vehicle body 1 to the water tank 31, reduce the vibration amplitude of the water tank 31, and further maintain the stability of the water tank 31 with the help of the traction rope.

[0027] One end of the vehicle body 1 is equipped with a shock-absorbing device 4, which includes an interface 51. The interface 51 is located at one end of the water storage tank 31, and a connecting pipe 52 is threaded onto the surface of the interface 51. A hose 55 is fixedly connected to one end of the connecting pipe 52, and a filter cartridge 56 is fixedly connected to the end of the hose 55 away from the connecting pipe 52. By setting up the shock-absorbing device 4, when the vehicle body 1 moves and shakes, the bending rod 41 works in conjunction with the damping 43 to compress the pressure spring 44. The elastic force generated by the pressure spring 44 can effectively buffer the vibration. Combined with the tension of the traction rope, the water storage tank 31 is kept stable, reducing the violent fluctuation of water and silt in the water storage tank 31 caused by shaking, preventing interference with temperature detection, ensuring the accuracy and reliability of temperature measurement data, and providing a precise basis for subsequent data analysis.

[0028] One end of the vehicle body 1 is equipped with a suction device 5, which includes a retaining ring 58. The retaining ring 58 is fixedly connected to the vehicle body 1, and a second motor 57 is fixedly connected to the surface of the retaining ring 58. By setting the second motor 57, the rotation drives the jacket 54, which in turn drives the hose 55 to flip, so that the filter cartridge 56 can be immersed in the paddy field water, so that the water pump 53 can draw paddy field water to replenish the water storage tank 31. After replenishment, the second motor 57 drives the jacket 54 again to drive the hose 55 to bend upward, reducing the drag of the hose 55 and affecting the movement of the vehicle body 1.

[0029] The drive end of the second motor 57 is fixedly connected to a jacket 54, which is fitted with a hose 55. A water pump 53 is fixedly connected to the surface of the hose 55. The inlet of the water pump 53 is connected to the hose 55, and the outlet of the water pump 53 is connected to the connecting pipe 52. By setting up the water pump 53, when the water in the water storage tank 31 evaporates due to long-term monitoring, the water in the paddy field is pumped to replenish the water storage tank 31. Specifically, when water needs to be replenished, the water pump 53 can pump the water collected by the filter cartridge 56 immersed in the paddy field water into the water storage tank 31 through the hose 55 to maintain the stability of the water volume in the water storage tank 31.

[0030] The working principle of this invention is as follows: By setting up a temperature measuring device 3, when in use, silt and water from the paddy field are added to the water storage tank 31. Then, the vehicle body 1 is started, and the vehicle body 1 drives the entire device to the outdoor paddy field ridge. Then, it stops and waits for sunlight. As the sunlight continues to shine, the simulated paddy field water temperature in the water storage tank 31 begins to change. By observing the thermometer 313, the water temperature of the paddy field can be determined. The first motor 314 is started, and the first motor 314 drives the gear 315 to rotate. The rotation of the gear 315 drives the temperature measuring device 313 to rotate. The thermometer 313 slides up and down to facilitate monitoring temperature changes at different water levels. Pulling the frame 32 upward causes it to move upward, which in turn moves the traction line 36, which in turn pulls the support plate 37 up. As the support plate 37 rises, the overall height of the water tank 31 is raised, simulating a rice paddy on a high slope. By rotating the threaded rod 317 and inserting it into the adjustment hole, the position of the crossbar 35 can be fixed. Rotating the retaining ring 39 disengages it from the threaded rod 38, allowing the water tank 31 to be separated from the support plate 37 and removed. By setting up a shock absorption device 4, swaying is inevitable during the movement of the vehicle body 1. At this time, the bending rod 41 works with the damping 43 to compress the pressure spring 44. The pressure spring 44 generates elastic force to reduce vibration. Together with the traction rope, the water tank 31 is kept stable, which is convenient for accurate detection. By setting up the suction device 5, the water in the water storage tank 31 will inevitably evaporate after a long period of testing. At this time, the vehicle body 1 will drive into the paddy field, and then start the second motor 57. The second motor 57 rotates and drives the jacket 54. The jacket 54 drives the hose 55 to flip. Then the filter cartridge 56 is filled with water from the paddy field and soaked. The water pump 53 is started and pumps water from the paddy field to replenish the water storage tank 31. Then the second motor 57 drives the jacket 54, and the jacket 54 drives the hose 55 to bend upward. At this time, the vehicle body 1 can continue to move to the next measurement point.

[0031] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
