Synchronous classifying and collecting device of grassland multi-type wind-eroded matters

Abstract

The invention relates to the field of study for measuring horizontal flux of multi-type wind-eroded matters, and particularly relates to a synchronous classifying and collecting device of grassland multi-type wind-eroded matters. The synchronous classifying and collecting device comprises a fixing rod vertically inserted into the ground; collecting devices are arranged in turn on two sides of the fixing rod in a left-right staggered way from top to bottom respectively; the collecting device comprises a ventilation box body, the left and right ends of the ventilation box body are opened, and the ventilation box body is fixedly connected with one side of the fixing rod; three layers of filter screens are vertically and uniformly spaced outward in turn at a left air outlet in the ventilation box body; a discharge opening is formed in the bottom of the ventilation box body corresponding to one side close to the air outlet; the filter screen on the middle layer directly faces the left edge position of the discharge opening. The synchronous classifying and collecting device provided by the invention has the advantages that the structure is simple; the design is reasonable; a plurality of wind-eroded matters can be collected at certain continuous height; meanwhile, classifying treatment is realized on a plurality of wind-eroded matters after entering the collecting device; the practicability is high; the study on migration of the grassland wind-eroded matters is more comprehensive and accurate; the synchronous classifying and collecting device is of great significance to the study of environmental protection and ecological system circulation.

Description

Technical field: [0001] The invention relates to the subject field of measuring the horizontal flux of multi-type wind-eroded substances, in particular to a synchronous classification and collection device for multi-type wind-eroded substances in grasslands. Background technique: [0002] Environmental protection is a topic that humans pay more and more attention to. Grasslands are prone to desertification after severe wind erosion, and the environment suffers huge losses. Studying the erosion, transportation and accumulation process of surface materials under the action of wind is of great significance for understanding the movement rules of wind-eroded materials and for desertification prevention and control. important theoretical and practical significance. Since the transport of wind-eroded materials mainly occurs near the surface and is dominated by leap motion, in order to study the law of wind-eroded leap motion, most of the existing collection devices are used to mea...

AI Technical Summary

Problems solved by technology

Since the transport of wind-eroded materials mainly occurs near the surface and is dominated by leap motion, in order to study the law of wind-eroded leap motion, most of the existing collection devices are used to measure the flux of a single type of material, sand and dust. For the flux measurement of other substances such as litter, the original data of the measurement is relatively simple, which cannot meet the needs of research on the migration and movement of multi-type wind-eroded substances. At present, there is no measurement device for synchronous collection of multi-type wind-eroded substances

In addition, the existing collection devices can only collect wind erosion materials at one or several heights, and the traditional collection devices obviously cannot effectively obtain the flux of wind erosion materials at a continuous height, which also affects the accuracy of data
