Description

Technical Field

[0001] This utility model belongs to the field of soil and water conservation monitoring and sampling technology, specifically a sampling device for soil and water conservation monitoring. Background Technology

[0002] Dynamic monitoring of soil erosion refers to the long-term investigation, observation, and analysis of the occurrence, development, harm, and benefits of soil erosion. Through soil erosion monitoring, we can understand its types, degrees, intensity, distribution characteristics, harms and impacts, occurrence and development patterns, and dynamic trends. This is of great significance for macro-level decision-making on comprehensive soil erosion control and ecological environment construction, as well as for the scientific, rational, and systematic deployment of various soil and water conservation measures. Among these measures, sediment is an important indicator in soil erosion surveys.

[0003] The specific design and structure of sampling devices for soil and water conservation monitoring may vary depending on the manufacturer and application requirements, but generally they include the following key components: a base, a fixing mechanism, and a sampling tube. The base supports the entire device and provides stable support. Its lower surface may be equipped with casters for easy movement. A sampling port is located in the middle. The fixing mechanism includes a recovery trough, a lead screw, feet, and a fixed handle. Rotating the fixed handle rotates the lead screw, causing the feet to move downwards and lifting the casters off the ground, increasing stability during sampling. The sampling tube serves as the main structure, with a rotating rod internally connected to it. A spiral blade is fixed on the rotating rod, which, when inserted into a medium such as mud or sand, drives the mud or sand into the sampling tube through the rotation of the spiral blade.

[0004] Currently, the sediment content sampling and determination devices used for soil and water conservation monitoring have low efficiency in separating sand and mud, which affects the monitoring efficiency. In the process of using existing sediment sampling devices, the filter plates inside the devices are mostly fixed and inconvenient to disassemble, making it difficult to clean and unclog the filter plates, which is inconvenient for people to use. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a sampling device for soil and water conservation monitoring.

[0006] The technical solution adopted by this utility model to solve its technical problem is a sampling device for soil and water conservation monitoring, including a vehicle body, a mounting frame on the vehicle body, a first motor bracket on the mounting frame, a first transmission motor mounted on the first motor bracket, a transmission rod rotatably mounted on the mounting frame, the output end of the first transmission motor being fixedly connected to the transmission rod, transmission gears at both ends of the transmission rod, two transmission screws rotatably mounted on the mounting frame, driven gears at the top ends of the two transmission screws, and the two transmission gears respectively meshing to drive a driven gear, transmission blocks on the two transmission screws, lifting plates on the transmission blocks, a first motor mounting plate on the lifting plate, a sampling motor mounted on the first motor mounting plate, an auger shaft at the output end of the sampling motor, a sliding hole on the vehicle body, the auger shaft being positioned above the sliding hole, a material conveying pipe sleeved on the auger shaft, and a discharge port on the material conveying pipe.

[0007] The vehicle body is equipped with a mounting frame, and the mounting frame has sliding grooves on both sides. A filter box is slidably mounted at each end of the mounting frame through the sliding grooves. A handle is hinged to the top of the filter box, and a filter hole is provided at the bottom of the filter box. A sealing door is hinged to the mounting frame, and a door handle is installed on the sealing door. The slidably mounted filter box can be easily installed and disassembled, facilitating the cleaning and replacement of filter components. The filter hole can effectively separate mud and other impurities in the soil, providing a relatively pure sample for subsequent mud and sand analysis.

[0008] The vehicle is equipped with two water tanks and two water pumps. Water storage blocks are located on both sides of the vehicle, and nozzles are installed on the water storage blocks. The water pumps are connected to the water tanks via a pumping pipe and to the water storage blocks via a delivery pipe. After water and soil samples are collected, the nozzles can spray water to rinse the samples during filtration, facilitating the removal of mud and water from the samples, ensuring the purity of the mud and sand, and improving the accuracy of the monitoring data.

[0009] Two sets of stirring shafts are rotatably mounted on the lifting plate. Each set of stirring shafts is equipped with a pulley, and the two sets of stirring shafts are connected by a transmission belt. The lifting plate is equipped with two secondary motor mounting plates, and each of the two secondary motor mounting plates is equipped with a stirring motor. The output end of each stirring motor is connected to a stirring shaft, and the stirring shaft is equipped with a stirring rod. By stirring, the sample is kept in a dynamic flow state, which can prevent particles such as mud and sand from clogging the filter pores in the early stage of filtration, making the filtration process smoother. At the same time, stirring can make the mud and sand in the sample come into full contact with the filter medium, accelerate the separation speed of mud and sand from other components, improve filtration efficiency, and save monitoring time.

[0010] A wastewater tank is installed below the filter box, and a drain valve is installed on the wastewater tank to prevent wastewater from flowing randomly and causing environmental pollution, which meets environmental protection requirements and also facilitates centralized treatment and analysis of wastewater.

[0011] Preferably, the No. 1 drive motor, sampling motor, stirring motor and water pump are all electrically connected to the battery on the vehicle body. This design enables the device to have an independent power supply system, eliminating the need for an external power source. This facilitates use in environments without power access, such as in the field, and improves the device's mobility and adaptability.

[0012] The advantages of this invention are as follows: After the sample is stirred with water, the mud and sand are separated from other impurities more thoroughly. When filtered through the filter holes of the filter box, the mud and sand pass through the filter holes more easily, reducing the possibility of impurities clogging the filter holes, improving the filtration speed and effect, and thus improving the efficiency of the entire sampling and processing process. The combined design of the mounting frame, filter box, filter holes, handle and sealing door facilitates the filtration of the extracted soil mixture. The filter box is slidably connected to the mounting frame through a sliding groove, making it easy to install and disassemble. Staff can easily remove it for cleaning, filter replacement and other operations. The filter holes effectively separate mud and sand and impurities in the soil, providing a relatively pure sample for subsequent analysis. Attached Figure Description

[0021] Please see Figure 1-5 As shown, a sampling device for soil and water conservation monitoring includes a vehicle body 1, a mounting frame 2 on the vehicle body 1, a first motor bracket 3 on the mounting frame 2, a first drive motor 4 mounted on the first motor bracket 3, a transmission rod 5 rotatably mounted on the mounting frame 2, the output end of the first drive motor 4 being fixedly connected to the transmission rod 5, transmission gears 6 being provided at both ends of the transmission rod 5, and two transmission lead screws 8 rotatably mounted on the mounting frame 2, with driven gears 7 provided at the top ends of the two transmission lead screws 8. Each of the transmission gears 6 meshes with a driven gear 7. Transmission blocks 9 are provided on the two transmission screws 8. Lifting plates 10 are provided on the transmission blocks 9. A first motor mounting plate 11 is provided on the lifting plate 10. A sampling motor 12 is installed on the first motor mounting plate 11. An auger shaft 13 is provided at the output end of the sampling motor 12. A sliding hole is provided on the vehicle body 1. The auger shaft 13 is located above the sliding hole. A material conveying pipe 24 is sleeved on the auger shaft 13. A discharge port is provided on the material conveying pipe 24.

[0022] During operation, in order to take samples, the first drive motor 4 is started, and its output end drives the drive rod 5 to rotate. The drive gears 6 at both ends of the drive rod 5 rotate accordingly. The drive gears 6 mesh with the driven gears 7, thereby driving the two drive screws 8 to rotate. The rotation of the drive screws 8 causes the drive block 9 to move on the screw, which in turn drives the lifting plate 10 to move up and down, thus adjusting the sampling height. The sampling motor 12 is started, and the auger shaft 13 at its output end rotates. The auger shaft 13 extends into the sliding hole below the vehicle body 1 to take samples. The samples are transported to the conveying pipe 24 through the auger shaft 13 and discharged from the discharge port to the filter box 23.

[0023] The vehicle body 1 is provided with a mounting frame 14. The mounting frame 14 has sliding grooves on both sides. A filter box 23 is slidably mounted at each end of the mounting frame 14 through the sliding grooves. A handle 25 is hinged to the top of the filter box 23. A filter hole 26 is provided at the bottom of the filter box 23. A sealing door 15 is hinged to the mounting frame 14. A door handle 16 is installed on the sealing door 15.

[0024] The vehicle body 1 is equipped with two water storage tanks 27 and two water pumps 28. Water storage blocks 29 are provided on both sides of the vehicle body 1. Spray nozzles 30 are provided on the water storage blocks 29. The water pumps 28 are connected to the water storage tanks 27 through a water suction pipe and to the water storage blocks 29 through a water delivery pipe.

[0025] Two sets of stirring shafts 19 are rotatably mounted on the lifting plate 10. Each set of stirring shafts 19 is equipped with a pulley, and each set of stirring shafts 19 is connected to the other via a transmission belt 22. Two second motor mounting plates 17 are provided on the lifting plate 10, and stirring motors 18 are mounted on each of the two second motor mounting plates 17. The output ends of the two stirring motors 18 are respectively connected to one stirring shaft 19, and stirring rods 20 are provided on the stirring shafts 19.

[0026] During operation, in order to filter the sample and obtain the sediment, the stirring motor 18 is started, and its output end drives the stirring shaft 19 to rotate. The pulleys on the two sets of stirring shafts 19 are connected by the transmission belt 22, so that the two sets of stirring shafts 19 rotate synchronously. The stirring rod 20 on the stirring shaft 19 rotates accordingly to stir the sample that needs to be stirred. At the same time, the water pump 28 on the vehicle body 1 draws water from the water storage tank 27, and delivers the water to the water storage block 29 through the water pipe. Then, the water is sprayed out by the nozzle 30 onto the sample, which can improve the filtration efficiency and effect, and make the sediment and other materials more fully separated.

[0027] A sewage tank 21 is provided below the filter box 23, and a sewage discharge valve 32 is provided on the sewage tank 21. The first drive motor 4, the sampling motor 12, the stirring motor 18 and the water pump 28 are all electrically connected to the battery on the vehicle body 1.

[0028] During operation, in order to remove the sediment for testing, use the door handle 16 to open the sealed door 15 on the mounting frame 14 to expose the internal filter box 23. By pulling the handle 25 hinged at the top of the filter box 23, the filter box 23 containing the filtered sediment can be slowly pulled out of the mounting frame 14 along the sliding grooves on both sides of the mounting frame 14. After the filter box 23 is pulled out, the sediment can be carefully removed from the filter box 23 with a shovel.

[0029] Working principle: In order to take samples, the first drive motor 4 is started, and its output end drives the drive rod 5 to rotate. The drive gears 6 at both ends of the drive rod 5 rotate accordingly. The drive gears 6 mesh with the driven gears 7, thereby driving the two drive screws 8 to rotate. The rotation of the drive screws 8 causes the drive block 9 to move on the screw, which in turn drives the lifting plate 10 to move up and down, so that the sampling height can be adjusted. The sampling motor 12 is started, and the auger shaft 13 at its output end rotates. The auger shaft 13 extends into the sliding hole below the vehicle body 1 to take samples. The samples are transported to the conveying pipe 24 through the auger shaft 13 and discharged from the discharge port to the filter box 23.

[0030] To filter the sample and obtain sediment, the stirring motor 18 is started, and its output drives the stirring shaft 19 to rotate. The pulleys on the two sets of stirring shafts 19 are connected by the transmission belt 22, so that the two sets of stirring shafts 19 rotate synchronously. The stirring rod 20 on the stirring shaft 19 rotates accordingly to stir the sample that needs to be stirred. At the same time, the water pump 28 on the vehicle body 1 draws water from the water tank 27, delivers the water to the water storage block 29 through the water pipe, and then sprays it onto the sample from the nozzle 30. This can improve the filtration efficiency and effect, and make the sediment and other materials more fully separated.

[0031] To remove the sediment for testing, use the door handle 16 to open the sealed door 15 on the mounting frame 14, exposing the internal filter box 23. By pulling the handle 25 hinged at the top of the filter box 23, slowly pull the filter box 23 containing the filtered sediment out of the mounting frame 14 along the sliding grooves on both sides of the mounting frame 14. After pulling out the filter box 23, the sediment can be carefully removed from the filter box 23 using a shovel.
