Sand sampler for monitoring soil wind erosion and desertification

Abstract

The invention relates to the technical field of monitoring of soil wind erosion and desertification, and discloses a sand sampler for monitoring soil wind erosion and desertification. The sand sampler comprises a bracket, a sand storm channel, a sand collecting barrel, a motor, a controller and a weighing sensor, wherein one end of the sand collecting barrel and the motor are coaxially connected with each other; the other end is arranged on the bracket in a rotatable manner; a sand collecting inlet is arranged on the barrel wall of the sand collecting barrel; a sand storm inlet and a sand storm outlet are respectively arranged at two ends of the sand storm channel; the sand storm outlet of the sand storm channel is arranged on the bracket; the sand storm outlet resists against the barrel wall of the sand collecting barrel; the weighing sensor is arranged on the bracket and below the sand collecting barrel; the controller is connected with the weighing sensor and the motor respectively; and the controller collects sand quantity data of the weighing sensor and transmits a control signal to the motor after carrying out data processing, so as to control the motor to drive the sand collecting barrel to load or unload the sand in a rotating manner. According to the sand sampler, the purpose that the sand collecting barrel continuously collects the sand in real time can be ensured, and energy-efficient automatic sand unloading and sand collecting are achieved.

Description

technical field [0001] The invention relates to the technical field of soil wind erosion monitoring, in particular to a sand collecting instrument for monitoring wind erosion and desertification of soil. Background technique [0002] Among the top ten environmental problems in the world in the 21st century, land desertification is the most serious problem, and the main cause of land desertification is soil wind erosion. Soil wind erosion refers to the action of airflow at a certain speed on loose soil, causing the displacement, transportation and accumulation of soil surface particles, resulting in the destruction of soil structure and the loss of materials in the soil. The problem of soil wind erosion has a long history and is widely distributed around the world. According to statistics, more than 900 million people in the world are harmed by soil wind erosion every year, and a quarter of the global area is threatened by desertification. The resulting economic losses Up to...

Problems solved by technology

The current sand collectors mainly have the following deficiencies: 1. The sand collectors of the cyclone separation type and the tipping bucket type 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 suitable for measuring the amount of sand transported. and sand flow structure; 2. Data measurement is mainly completed by manpower, and continuous data collection cannot be realized; 3. It is not possible to alarm and automatically unload sand when the sand reaches a certain quality

Therefore, the existing sand collector cannot meet the current information needs
