Embodiment

Further describe below in conjunction with accompanying drawing, and provide embodiment:

A kind of novel sand-taped instrument described in the utility model, this sand-taped instrument is comprised of the husky passage 1 of collection, training for sediment passage 2, sand-storing box 3, fixed head 8, sand-storing box shutoff screw 4, closing cap 5; Training for sediment passage 2 is that dip-parallel arranges, and the inclination angle is 45 °, and up and down each passage of training for sediment passage 2 oblique arrangement is UNICOM not mutually, and training for sediment passage 2 cross sections be square; According to the oblique arrangement of training for sediment passage 2, collect husky passage 1 for arrangement long on the lower weak point, adopt respectively oblique section 6 to be connected with normal section with the joint face of training for sediment passage 2 and alternately be connected; Dip-parallel according to training for sediment passage 2 is arranged, sand-storing box 3 is long array under the upper weak point, 4 sand-storing boxs in sand-storing box 3 bottoms vertically are arranged in parallel, the cross section is rectangle, links to each other with training for sediment passage the closer to the earth's surface, and length is longer, all the other sand-storing box horizontal parallel of top are arranged, the cross section is square, and more upwards length is shorter, and sand-storing box 3 adopts respectively oblique section 6 to be connected with normal section with the joint face of training for sediment passage 2 alternately to be connected; Training for sediment passage 2 one ends are connected with the husky passage 1 of collection, the other end is connected with sand-storing box 3, forms the passage of a UNICOM, and integrate husky passage 1, training for sediment passage 2 and the sand-storing box 3 of each layer interconnect, become the "the" shape connecting pipe, the connecting pipe of each layer vertically superposes; Sand-storing box 3 one sides are the square-shaped hopper shape, are sample tap in the bottom surface of square-shaped hopper shape, at sample tap shutoff screw 4 are housed, and the both sides mounting plate 8 at the husky passage 1 of collection and sand-storing box 3 makes sand-taped instrument become as a whole; Closing cap 5 is flat " U " shape cell body, and three are opened wide, and is socketed on the husky passage 1 of collection, and the grains of sand enter sand-taped instrument inside during being used for preventing non-observation; The material of sand-taped instrument is stainless steel, iron sheet, organic glass or PVC material, adopts sheet material processing or rectangle pipe material directly to make;
