Continuous runoff sediment sampling and measuring device for water and soil conservation monitoring

The utility model discloses a runoff sediment continuous sampling and measuring device for water and soil conservation monitoring. Mounting rack, an air cylinder is arranged on the inner bottom surface of the mounting frame; a notch frame is mounted at the movable end of the air cylinder; a driving shaft and a driven shaft are arranged between the inner side walls of the notch frame; one end of the driving shaft penetrates through the notch frame and extends to the outside; when the runoff sediment is shallow, the sediment is removed; the air cylinder can drive the notch frame to stably move downwards; therefore, the sampling box can enter runoff sediment; the use according to different water flow depths is convenient; the notch frame is supported in an auxiliary manner by arranging the shear type rod; meanwhile, vibration generated when the servo motor 12 works is transmitted to the shear type rod through the notch frame, so that the shear type rod stretches out and draws back in thevertical direction, the s
