When off working state, the guiding bracing frame among the present invention is in obliquity, and the working direction of itself and power carrying vehicle roughly is 120 degree angles; In the time of in working order, the support cylinder bracing frame jack-up of will leading makes it be in vertical state.During sampling, hoist cylinder may command oil motor to lower slider, drives sampling pipe rotation by oil motor along the guiding bracing frame, and the mode by cover bores realizes the soil collection.The use of displacement multiplication mechanism can increase the stroke of oil motor, thereby realize profound soil collection under the constant situation of guiding bracing frame height effectively.After sampling was finished, the hoist cylinder action made oil motor move up along the guiding bracing frame, so that sampling pipe is extracted from soil.Thus, be embedded in the soil sample that soil in the sampling pipe is required collection.Under off working state, on the oil motor sampling pipe can be installed.Can before sampling, determine corresponding sampling depth, and then select for use suitable sampling pipe to be installed on the oil motor according to the actual needs of soil sampling.Compare with existing artificial collection pedotheque, utilize the soil collecting device among the present invention to carry out the soil collection, not only can increase work efficiency, guarantee to gather the precision of soil, and can increase the degree of depth that soil is gathered.
As improvement of the present invention, above-mentioned displacement multiplication mechanism comprises first sprocket wheel, second sprocket wheel, the 3rd sprocket wheel, the 4th sprocket wheel, first chain and second chain; Described first sprocket wheel and second sprocket wheel are connected on the piston rod of described hoist cylinder, above-mentioned first sprocket wheel and the second sprocket wheel positioned opposite; Offer first elongated window and second elongated window on two of described guiding bracing frame relative sides respectively, described first sprocket wheel stretches out from first elongated window, and second sprocket wheel stretches out from second elongated window; Described the 3rd sprocket wheel be connected the guiding bracing frame the bottom, with first sprocket wheel be in the guiding bracing frame the same side; Described the 4th sprocket wheel be connected the guiding bracing frame top, with second sprocket wheel be in the guiding bracing frame the same side; First chain is on first sprocket wheel and the 3rd sprocket wheel, and an end of first chain is fixedly connected on the slide block, and the other end is fixedly connected on the guiding bracing frame; Second chain is on second sprocket wheel and the 4th sprocket wheel, and an end of second chain is fixedly connected on the slide block, and the other end is fixedly connected on the guiding bracing frame.
Above-mentioned displacement multiplication mechanism has utilized the multiple relation between rope and the travelling block to realize the displacement multiplication of oil motor.Above-mentioned first sprocket wheel and second sprocket wheel are equivalent to travelling block, and the 3rd sprocket wheel and the 4th sprocket wheel are equivalent to fixed pulley, and first chain and second chain are equivalent to rope.Hoist cylinder is connected guiding bracing frame bottom: the piston rod of hoist cylinder stretches out, and oil motor moves down, mechanism's application of force pulling oil motor that be made up of first chain, first sprocket wheel and the 3rd sprocket wheel this moment; When the piston rod of hoist cylinder shrinks, move mechanism's application of force pulling oil motor that be made up of second chain, second sprocket wheel and the 4th sprocket wheel this moment on the oil motor.When hoist cylinder was connected guiding bracing frame top, the piston rod of hoist cylinder shrank, and oil motor moves down; The piston rod of hoist cylinder stretches out, and moves on the oil motor.
Improve as of the present invention, above-mentioned sampling pipe interconnects by screw thread and hydraulic motor output shaft again.
Sampling pipe removably links to each other with hydraulic motor output shaft by the mode that is threaded, and has made things convenient for the replacing of sampling pipe.
Improve as of the present invention again, connect a guiding support set on described guiding bracing frame, described sampling pipe passes above-mentioned guiding support set.
Above-mentioned guiding support set can be in the upper and lower effect of playing guiding when mobile of sampling pipe, and the guiding support set can prevent that sampling pipe from swinging when oil motor is worked.
