Sand collecting device and method

Abstract

The invention discloses a sand collecting device and a method thereof, and relates to the technical field of wind erosion monitoring, wherein the device comprises a sand collecting opening, a sand box, a sand filling device, a switchable base plate, a switch plate control motor, a weigh box, a compound sensing probe and a data acquiring and controlling device; the sand collecting opening is connected with the sand box, and the bottom opening of the sand collecting opening faces to the center of the sand filling device; the sand filling device is positioned in the sand box, and is fixedly mounted on the switch base plate, and the bottom part of the sand filling device is provided with the weigh box; the weigh box is connected with the data acquiring and controlling device; the compound sensing probe is mounted on the top part of the sand collecting opening, and is connected with the data acquiring and controlling device; the data acquiring and controlling device is mounted on the sand box; the switchable base plate is mounted at the bottom part of the sand box; and the switch plate control motor is mounted in the sand box and is connected with the data acquiring and controlling device. According to the invention, the weight of sand can be measured automatically and continuously, the sand can be unloaded automatically, and the wind speed of the sand collecting opening can be measured accurately at the same time.

Description

Technical field [0001] The invention relates to the technical field of wind erosion monitoring, in particular to a sand collecting device and a sand collecting method thereof. Background technique [0002] Soil wind erosion is one of the important factors that cause grassland desertification and soil quality degradation in northern China, and it has a significant negative impact on the socio-economic and ecological environment in northern my country. The northern part of my country is the most severe area of ​​wind erosion disasters in the world. Due to excessive reclamation and grazing, climate change and other factors, the soil quality of pasture and dry farmland in semi-arid areas has degraded and desertified, especially the rapid development of desertification in farming and pastoral areas. The local social economy and ecological environment brought catastrophic harm. At the same time, dust aerosols that enter the atmosphere due to wind erosion have become a major climate pro...

Problems solved by technology

Among them, the cyclone separation type, tipping bucket type and other sand collectors are usually used for single-point (layer) measurement, and it is not easy to make a structure for multi-layer measurement of the longitudinal section, which is not conducive to measuring the amount of sand transported and the structure of wind-blown sand flow.

[0005] The multi-port type is the most common profile sediment discharge measurement equipment. The existing problems are that the sediment collection volume needs to be manually measured and manually emptied, and the continuous measurement function cannot be realized. At the same time, each sand collection port (also is the wind speed of each layer), and can only be processed by the average wind speed, which affects the calculation of the amount of sand transported and the structure of the sand flow
