[0002] Soil loss refers to the phenomenon that due to natural or human factors, rainwater cannot be absorbed locally, flows down and washes the soil, causing the loss of water and soil at the same time. Soil and water conservation monitoring refers to the long-term investigation, observation and analysis of the occurrence, development, harm and benefits of soil and water loss.

[0003] At present, the method for measuring soil erosion is generally to separate the water content and the sand content in the sample and then detect the weight to measure the result. In order to reduce the water content in the sand, the common measuring device generally heats the separated sand. However, the water vapor evaporated by heating will also contain a small amount of sand. After the sand is discharged, it will affect the net weight of the sand, thereby affecting the accuracy of the final data of the soil erosion measurement. In order to make the measurement result more accurate, a soil erosion measurement device for soil and water conservation monitoring is proposed. Utility Model Content

[0020] The working principle and use process of the utility model are as follows: when in use, open the funnel cover 8, pour the sample water from the water inlet funnel 6, the sample water enters the water inlet pipe 7 from the water inlet funnel 6, and then enters the filter cup 17. When the sample water enters the filter cup 17, the first water baffle plate 5 is opened. After the sample water enters the filter cup 17, the first water baffle plate 5 is closed. The sample water entering the filter cup 17 is first filtered by the filter plate 4. The filter plate 4 will filter the sediment in the sample water. The filtered water passes through the filter plate 4 and is collected at the bottom of the filter cup 17, and then enters the water cup 18 through the outlet pipe 3.

The hot air will dry the sediment. The water vapor generated by the drying passes through the filter 13 upwards, and the filter 13 will filter out the sediment contained therein to prevent the sediment from being lost with the water vapor. After the drying is completed, the control valve 19 can be opened to drain the water. If there is any residue, the control valve 19 can be kept flowing, the sealing cover 11 can be tightened, and the hot air blower 16 can be kept turned on for a period of time to dry and discharge the water vapor in the water cup 18. At this time, the weight weighed by the weighing device 1 is the net weight of the sediment. The measurement personnel can calculate according to the data to measure the accurate data of soil and water loss. The measurement personnel can also unscrew the filter cup 17 from the water cup 18 after the drying is completed, and then open the cup cover 10 to take out the sediment in the filter cup 17 and weigh it separately for subsequent calculations.
