Problems solved by technology

For example, the outer layer of the existing sand collection bag is made of kraft paper, and the inner layer is made of fiber gauze material. This leads to the fact that when the dust is collected after the measurement, the inner side of the sand collection bag is easy to stick to the sand and it is difficult to pour it out, which affects the accuracy of the test and also reduces improved work effi

Abstract

The invention relates to a near-surface short-time wind-sand flow sand collection tester. The tester comprises a sand collection box, a sand collection cylinder and a collection device. The sand collection box is vertically arranged. The sand collection cylinder is transversely arranged on the sand collection device. The first end of the sand collection cylinder stretches out of the interior of the sand collection box, and the second end of the sand collection cylinder is arranged in the sand collection box. The collection device is magnetically connected to the second end of the sand collection cylinder. According to the invention, by magnetically connecting the collection device and the sand collection cylinder, disassembly and assembly convenience is improved and test precision and work efficiency are improved.

Description

technical field [0001] The invention relates to a device for measuring the flow state of wind-blown sand in a short time in the field, in particular to a short-time wind-blown sand flow sand collection measuring instrument near the surface. Background technique [0002] Desertification has become one of the major environmental problems in the world. Due to wind and sand movement, wind erosion and wind deposits and other wind and sand landforms appear on the surface, and wind blown sand and dust are transported vertically and horizontally, even long distances, seriously affecting the quality of the atmospheric environment. Since the 1990s, in northern my country, the number of sandstorms has gradually increased, and the prevention and control of sandstorm disasters has increasingly become a major topic in the field of environmental research in my country. The primary issue for effective desertification control is to accurately grasp the law of sandstorm movement. The sand co...
