Automatic weighing sand collector

Abstract

The invention discloses an automatic weighing sand collector which comprises a sand inlet pipe, a vertical air duct, a sand conveying pipe, an automatic windproof piece, a sealing box body, a sand containing basin, a support, an electronic balance, an automatic lifting platform and the like, the sand inlet pipe is communicated with the side face of the vertical air duct, an air outlet is formed in the upper portion of the vertical air duct, and direction adjusting fan blades are arranged at the top of the vertical air duct; the vertical air duct is rotationally connected with the sealed box body; the sand conveying pipe is positioned in the sealed box body and is communicated with the bottom of the vertical air duct; and an automatic windproof piece is hinged to the edge of a sand outlet in the bottom of the sand conveying pipe. The sand containing basin is located under the sand outlet and supported by the support, and the electronic balance is located under the sand containing basin and supported by the automatic lifting platform. The two ends of the transmission frame are fixedly connected with the automatic lifting platform and the automatic windproof piece respectively. The problems that an electronic balance in an existing automatic weighing sand collector is loaded for a long time, and accuracy is affected are solved, and meanwhile the technical problem that it is difficult to achieve a quiet wind environment in a cavity of the existing sand collector is solved.

Description

Technical field[0001]The present invention relates to the field of water and soil loss monitoring, and more particularly to an automatic weighing sander.Background technique[0002]The retreat is a common equipment for monitoring wind erosion in the wind and sand area. The existing clip structure is mainly composed of part of the sand, the sand box / pot, exhaust port, the rotating tail, etc., and most of them cannot be automatically weighed. It can only rely on labor.[0003]In addition, there is a German-producing UGT-FE automatically called the sand, and an electronic balance is installed under the smooth sandbas, and the data collector is configured, and the time interval is set, it can be automatically called the sandbane. The weight can be calculated to calculate the sand volume by the difference between the weight of the two times. However, the following two reasons will result in the above-mentioned sandstick: First, enter the sand and the outside air, and cannot guarantee the i...

AI Technical Summary

Problems solved by technology

However, the following two reasons will cause inaccurate weighing of the above-mentioned sand collector: one is that the sand inlet is connected to the outside air, which cannot ensure that the inner cavity of the sand collector maintains a calm wind environment, resulting in inaccurate weighing; The basin has been placed on the electronic balance, and the long-term load will cause the sensitivity of the electronic balance to decrease, thereby affecting the accuracy of weighing
