The utility model further provides that the reset component comprises a fixed block, a second connecting rod, a second spring, a sliding chute, a sliding block and a through hole, wherein the fixed block is fixedly arranged at one end of the bottom plate, the second connecting rod is movably arranged in the fixed block, and a limiting block is fixedly arranged at one end of the second connecting rod.
Through adopting above-mentioned technical scheme, the bottom plate provides fixedly for the fixed block provides the support for the second connecting rod, and movable mounting's second connecting rod simultaneously makes the second connecting rod can remove inside the fixed block, and the stopper can apply spacingly to the second connecting rod, prevents that the second connecting rod breaks away from the fixed block.
The utility model is further characterized in that a sliding block is fixedly arranged at one end of the storage box, and a sliding groove for the sliding block to slide is formed in the end face of the storage box.
Through adopting above-mentioned technical scheme, slider and spout cooperate for when control receiver's direction of movement, guarantee that the stripper plate applys pressure to the swash plate, the receiver can remove along the spout.
The utility model is further characterized in that a second spring is sleeved outside the second connecting rod, and the fixed block is connected with the sliding block through the second spring.
Through adopting above-mentioned technical scheme, the sustainable elasticity of applys the receiver of second spring guarantees that the stripper plate releases the extrusion back to the bevel board, and the second spring helps the receiver to reset, collects sample soil.
The utility model is further characterized in that a through hole for the passage of the sampling tube is formed at one end of the bottom plate, and a fixing frame is fixedly arranged at one end of the storage box.
Through adopting above-mentioned technical scheme, the through-hole provides the space of removal for the sampling tube passes through the bottom plate, and the mount can be fixed the bottom plate on the surface of sample soil, prevents to remove at the position of sampling in-process bottom plate, influences the sample of sampling tube.
The utility model is further characterized in that the top end surfaces of the extrusion plate and the inclined plate are arranged in an arc shape, and the diameter of the sampling tube is larger than that of the thimble.
Through adopting above-mentioned technical scheme, the top terminal surface of stripper plate and swash plate is circular-arc setting for the stripper plate can extrude the swash plate position when contacting with the swash plate and remove, guarantees its atress direction, and the swash plate can not influence the removal of stripper plate, and the diameter of sampling tube is greater than the diameter of thimble, makes the inside that the thimble can enter into the sampling tube, and it is ejecting with the soil of sampling tube inside, falls into receiver inside.
In summary, the utility model has the following advantages:
According to the utility model, by arranging the first spring, the ejector pin, the inclined plate, the extruding plate, the sliding block, the second connecting rod and other components, when a worker uses the sampling device, the worker only needs to apply pressure to the movable plate to drive the sampling pipe to move downwards to sample soil, meanwhile, the extruding plate extrudes the inclined plate to prevent the storage box from influencing the movement of the inclined plate, after the sampling is finished, the first spring can help the sampling pipe to reset, and when the position of the sampling pipe moves upwards, the ejector pin can eject the soil in the sampling pipe and drop into the storage box, so that the sampling of the soil can be finished.
