The lower end of the connector is provided with a clamp, which holds a sampler. The pull rod is a sleeve structure, with a push rod sleeved inside. The sampler includes a sampling barrel, which is sleeved with a piston rod. When the push rod is pressed down, it contacts the piston rod, causing it to move toward the sampling port of the sampling barrel. The patent aims to provide a soil sampling device that is easy to operate, saves time and effort, and prevents soil samples from falling.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: (1) Through the setting of the driving device in the present invention, the cross board, the circular shell, the motor, the arc-shaped slide plate and the spring piece cooperate with the cushion block. The motor shaft drives the rotating cylinder to rotate forward, and the rotating cylinder drives the spiral blade to rotate forward. The chamfer of the rotating cylinder screws into the soil, and the spiral blade on the rotating cylinder drives the rotating cylinder into the soil. When the rotating cylinder enters the soil, the rotating cylinder moves downward, the rotating cylinder drives the motor to move downward, the motor drives the cross board to move downward, the cross board drives the circular shell to move downward, and the circular shell slides downward in the arc-shaped slide plate. When reaching the depth of soil collection, the motor shaft drives the rotating cylinder to rotate in reverse, the rotating cylinder drives the spiral blade to rotate in reverse, and the reverse rotation of the spiral blade drives the rotating cylinder to screw out of the soil. The mud-blocking pipe in the rotating cylinder blocks the soil from falling, enabling the rotating cylinder to conveniently collect the soil. And under the elastic force of the spring piece, the spring piece on the cushion block buffers the cross board, and the spring piece reduces the shaking amplitude generated downward by the cross board, preventing a large deviation in the soil sampling position, thereby avoiding the problem of poor sampling effect of the soil sampling device.

[0017] (2) The present invention uses the setting of a moving device to make the L-shaped platform, protective cylinder, square plate, cylinder and positioning pile cooperate with rollers. The roller drives the L-shaped platform to move. The protective cylinder on the L-shaped platform protects the rotating cylinder from being damaged by collision, allowing the staff to move the collection device conveniently and step on the disc on the positioning pile. The positioning pile moves downward in the cylinder and is inserted into the soil to prevent the collection device from being inaccurately positioned during collection, thereby avoiding the problem of inconvenient positioning of the collection device.

[0018] (3) The present invention sets up a grass clearing device, so that the L-shaped plate, baffle, chamfered rod and strip plate cooperate with the arc-shaped throwing plate. The L-shaped platform drives the L-shaped plate to move, and the L-shaped plate drives the baffle plate to move to prevent grass and trees from damaging the driving device. The L-shaped plate drives the chamfered rod to move, and the chamfered rod on the L-shaped plate scrapes the weeds on the soil to prevent the weeds from affecting the downward collection of the rotating drum. The L-shaped plate drives the strip plate to move, and the strip plate drives the arc-shaped throwing plate to move, and the arc-shaped throwing plate removes the roots of the weeds to prevent the roots from blocking the speed of the rotating drum to collect downward, thereby avoiding the problem of slow collection speed of the collection device.

[0019] (4) The present invention sets a flushing device so that the water tank, L-shaped water pipe, electric nozzle and U-shaped plate cooperate with the circular plate. The water pump on the L-shaped water pipe sucks water from the water tank, and the water flows upward to the L-shaped water pipe. The electric nozzle sprays the water in the L-shaped water pipe, and the water flows toward the rotating drum, so that the soil brought out by the spiral blades on the rotating drum is washed away, and the flushing water accumulates on the circular plate on the U-shaped plate. The water is discharged through the outlet pipe on the circular plate, preventing the flushing water from splashing and damaging the collection device, thereby avoiding the problem of the collection device being damaged during flushing.
