Embodiment Construction

[0029] Such as figure 1 As shown, the present invention includes a support 2, a sand collecting unit 1, a data collector 4 and a power supply.

[0030] The support 2 is a vertical tubular structure, and the lower end of the support 2 can be installed with a plug so that the support 2 is fixed on the ground. Inserting brazing and support 2 are detachable structures. The sand collection unit 1 is fixed on the support 2 through the connecting rod 25, and the sand collection unit 1 is used to collect and measure the sand and dust in the wind and sand flow; in specific applications, several different heights can be installed on the support 2 according to actual needs. Sand collection unit 1. Each sand collection unit 1 is connected to the data collector 4 through a cable 3, the cable 3 can extend from the top of the support 2 into the inside of the support 2, and then extend from the bottom of the support 2 to connect with the data collector 4 . In order to prevent the cable 3 ...

Abstract

The invention provides an automatic continuous weighing type sand collector. The structure of the automatic continuous weighing type sand collector comprises a bracket, a sand collecting unit, a data acquisition device and a power supply. The sand collecting unit comprises an enclosed case body, a wind pressure reducer, a cyclone separator, a sand collecting box and a weight sensor. During the sand collecting process, sand discharged from an outlet of the wind pressure reducer falls into the sand collecting box spontaneously, the sand in the sand collecting box is weighed by using the weight sensor, and the weighing data is transmitted to the data acquisition device. The automatic continuous weighing type sand collector provided by the invention is high in degree of automation and low in maintenance cost, can effectively simulate natural conditions, and is suitable for high-precision automatic monitoring of wind-sand activity in the wild.

Description

technical field [0001] The invention relates to a sand collector, in particular to an automatic and continuous weighing sand collector. Background technique [0002] The main cause of land degradation in arid and semi-arid regions is soil wind erosion. The main external force of soil wind erosion is sandstorm activity, and the direct indicator reflecting the intensity of wind erosion activity is sand flux. The monitoring of near-surface wind and sand activity is the main content of soil wind erosion ground monitoring. It mainly monitors wind and sand flow. The monitoring results can provide basic data for soil wind erosion detection and forecast. At present, the detection technologies for wind and sand flow at home and abroad are mainly divided into three categories: the first type is to use pressure sensors, sound sensors or optical sensors to indirectly observe the intensity of wind and sand flow; the second type is to use mechanical sand collectors ( Such as flat mouth s...
