The principle of this programme is such: for determining the density of Subgrade soil, first piston is buried in the earth, the vertical movement of the piston of mast bottom carrys out transmission by adjusting handle by the first bevel gear and the second bevel gear, the adjusting handle be cemented on the second bevel gear drives the first bevel gear to rotate, thus make screw rod drive first connecting rod motion, due to first connecting rod, second connecting rod and third connecting rod are all connected on slide rail by sliding sleeve, the mast motion that second connecting rod is connected, therefore, by first connecting rod, the whole system of second connecting rod and third connecting rod composition moves along fixed rack, the volute spring of measurement is installed between second connecting rod and drum, by the resistance squeezing soil, volute spring is compressed, cause second connecting rod and third connecting rod close, due to drum cylindrically, the periphery of drum is stained with blank sheet of paper, finally be recorded on the drawing of the drum being fixed on rotation by record pencil.
The invention has the advantages that: it is simple, easy to operate that this soil density detects meter structure, equipment operating simply, can improve the work efficiency that soil density detects.
Preferably, the bottom of described drum is provided with discoid pulley, and described pulley is connected with motor by cable wire, and described pulley is provided with the annular groove of guiding cable wire, and the rotation of drum is by spring along with the cable wire be around on pulley, and realized by driven by motor.
Preferably, described screw rod is fixed by screws on first connecting rod, installation, convenient disassembly.
Preferably, the piston on described vertical mast is taper, is convenient to during piston places into the soil.
Accompanying drawing explanation
