The working principle of the soil sampler with the cutting function is as follows: firstly, unscrewing a locking bolt and a fixing bolt, adjusting the positions of a quantitative soil sampling head 6 and a sampling drill bit 3, adjusting the sampling amount and the sampling depth, then screwing the locking bolt and the fixing bolt, inserting a limiting rod 7 into the sliding seat and inserting the limiting rod into the ground to enable the sampling drill bit 3 to be in contact with the ground, starting a driving motor 2 to drive a scale rod 4, the quantitative soil sampling head 6 and the sampling drill bit 3 to rotate, pressing a pressing table 8 by an operator, pressing the sampling drill bit 3 into the ground, enabling soil to enter the interior of the quantitative soil sampling head 6, discharging air in the quantitative soil sampling head 6 through an air outlet in the soil entering process, directly inserting the quantitative soil sampling head 6 into the ground when the soil at a shallower position is sampled, enabling the soil on the surface to enter the upper position of the sampling head as a part of sampling soil, and separating the soil on the surface from the sampling soil when the sampling soil is taken out, when the soil with deeper sampling is sampled, firstly, the equipment is used for taking out the soil above the position to be sampled, after the soil is extracted, the soil in the soil sampling head 6 is drawn out, the operation is repeated, the soil reaches the depth to be sampled, finally, the soil sampling head 6 is used for downwards sampling again, the soil above the soil enters the inside of the scale bar 4, wherein 4 is hollow, only the push rod 201 and the push rod 203 which move vertically and directly are kept relatively static in the sampling process without extrusion, working interference is not generated, when the mounting table 1 is contacted with the ground, the sampling is finished, the rotary driving electric cylinder 105 is started, the driving rack 107 is driven to move, the driving shaft 101 and the rotary shaft are driven to rotate, the cutting knife 9 is driven to rotate to the middle position of the sampling drill bit 3, the soil is cut off in the rotating process, when the sampling drill bit 3 is lifted upwards after sampling is finished, the positioning bolt is unscrewed to release the limit of the pressing plate 207, the pressing plate 207 is pressed downwards, the elastic ejector rod 202 is driven to eject out of the push-down rod 201 and bend, the clamping ring 208 is contacted with the limiting ring 205, the push-down rod 201 and the elastic ejector rod 202 are driven to fall, the soil outside the quantitative soil sampling head 6 is pushed down, the quantitative soil sampling head 6 and the sampling drill bit 3 are lifted from the ground, the pressing plate 207 is pulled upwards to retract the elastic ejector rod 202 into the push-down rod 201, and the sampling soil inside the quantitative soil sampling head 6 is collected and detected.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
