Embodiment Construction

[0015] Such as figure 1 As shown, a hand-operated two-way sample preparation instrument includes a base 1 on which two connecting rods 2 and a transmission shaft 22 are mounted. Shape, the port of the S-shaped upper section is equipped with a pressure plate 3, and the pressure plate 3 of the present embodiment is a circular steel cake. The S-shaped lower section is the transmission rod engraved with threads, and the upper section and the middle section are installed on the base 1 through the sleeve 13 with balls on the inner wall. The two linkage rods 2 are symmetrically fixed on the base 1 through the sleeve 13 with balls on the inner wall; one end of the transmission shaft with the gear is suspended outside the base, and the rest is installed on the base 1 through the bearing 14 and the pin shaft 15 . The two connecting rods 2 are symmetrically distributed on the base 1, and the board surfaces of the pressure plates 3 on the two connecting rods face each other. A sample pr...

Abstract

The invention discloses a hand-operated type two-way sampling instrument comprising a material containing mould, a sampling container and a base, wherein the sampling container is arranged in the material containing mould, the material containing mould is fixed on the base, the base is provided with two linkage rods and a transmission shaft, one end of each linkage rod is provided with a pressurization plate, and the material containing mould is positioned between the plate faces of the two pressurization plates; the other end of the two linkage rods is provided with a transmission rod, the left part and the right part of the transmission shaft are engraved with screw threads which are matched with the transmission rods at the left side and the right side, the side of the transmission shaft is provided with a crank handle, and gears on the crank handle and gears on the transmission shaft are mutually coupled. The invention realizes uniform sampling by mechanical transmission, the transmission of a uniform-speed motion of the whole instrument is realized by hand operating in operation, and the pressurization plates are driven only by the rotation of the hand-operated rod, therefore, the two pressurization plates always keep opposite uniform-speed linear motions no matter how the hand-operated speed is, and finally, uniform sampling is realized.

Description

technical field [0001] The invention relates to a hand-operated two-way sample preparation instrument, in particular to a mechanical remolded soil sample preparation device, which belongs to the soil engineering sample preparation instrument. Background technique [0002] At present, uniform soil samples with a certain density and water content are required in scientific research, teaching, and production practice, but the existing sample preparation equipment cannot meet the standards. Classical compaction method) to realize sample preparation, because the force state of the soil sample is not uniform, fundamentally speaking, it is impossible to make a uniform soil sample. Although modern soil mechanics has made considerable progress since Terzaghi put forward the effective stress principle in 1923. But in the field of geotechnical testing, this is still a common problem that needs to be overcome urgently. Contents of the invention [0003] The purpose of the present in...
