Furthermore, handles 16 are installed on both sides of the mounting frame 1, which is convenient for the staff to push the present device to move. A battery pack 17 is provided under the handle 16, and the battery pack 17 is connected to the mounting frame 1. In the present device, the battery pack 17 is used as the power source for all electronic components of the present device, thereby improving the convenience of the present device.

[0023] Both ends of the mounting frame 1 are hinged with locking plates 3, and the cross section of the locking plates 3 is L-shaped. Figure 1 As shown, the locking plate 3 is in a retracted state. Figure 5As shown, the locking plate 3 is in the unfolded state. When the universal wheel 2 contacts the horizontal ground, the locking plate 3 is unfolded and its lower end surface is also in contact with the ground. Since one end of the locking plate 3 is hinged to the mounting frame 1, it can still be guaranteed to contact the ground when facing an uneven or sloping ground. Then, when the locking plate 3 is unfolded, the staff holds the handle and steps on the locking plate 3, which can limit the device. Then, in this state, the road soil sampling operation is carried out to ensure the stability of the device.

[0024] A mounting plate 4 is provided on the inner side of the mounting frame 1, and the mounting plate 4 is connected to the mounting frame 1 through a limiting assembly. Figure 1 and Figure 4 As shown, the limit assembly includes a fixed block 11, and the fixed block 11 is evenly provided with a plurality of groups, and the fixed block 11 is connected to the mounting frame 1. In the present embodiment, the fixed block 11 is evenly provided with four groups, and the lower end surface of the fixed block 11 is flush with the lower end surface of the mounting frame 1, and a slide bar 12 is installed on the upper end of the fixed block 11, and the upper end of the slide bar 12 passes through the mounting plate 4 and is connected to the mounting frame 1, thereby, under the action of the slide bar 12, the mounting plate 4 can only move up and down in the mounting frame 1, and further, a buffer block 15 is sleeved on the outer side of the slide bar 12, and the bottom of the buffer block 15 is connected to the fixed block 11 through a spring, and the spring is also sleeved on the slide bar 12, and the buffer block 15 moves on the slide bar 12, and the cooperation of the buffer block 15 and the spring can play a buffering role when the mounting plate 4 falls accidentally.

The motor 6 is located above the aggregate shell 5 and is connected to the aggregate shell 5 through a bracket. An outer cylinder 7 is installed below the mounting disk 4, and the upper end of the outer cylinder 7 passes through the mounting disk 4 and is flush with the upper end surface of the mounting disk 4, so the inner cavity of the outer cylinder 7 is directly connected with the inner cavity of the aggregate shell 5, and the lower end of the outer cylinder 7 is connected with the outside, and a spiral soil drill 8 is provided on the inner side of the outer cylinder 7, and the spiral soil drill 8 is connected to the output end of the motor 6. When working, the spiral soil drill 8 contacts the road soil. After starting the motor 6, the motor 6 drives the spiral soil drill 8 to rotate. The spiral soil drill 8 itself has spiral blades, so the spiral soil drill 8 will gradually drill downward with the passage of time, thereby transmitting the sample to be tested from the underground through the outer cylinder 7 and then to the aggregate shell 5.

[0026] Two groups of symmetrically arranged collecting boxes 9 are arranged on the outer side of the outer cylinder 7. The collecting boxes 9 are connected to the mounting plate 4 by bolts.

Therefore, when the detected samples are transmitted to the aggregate shell 5, they can fall from the discharge ports 10 into the collecting box 9 due to the centrifugal force, so as to be easily collected. In the continuous sampling operation, the samples at different locations can be stored by replacing the collecting box 9. Therefore, the present device can meet the continuous sampling work at different locations during the road construction process, and at the same time, the samples can be conveniently stored during the sampling process.

[0027] Furthermore, the upper end of the collecting box 9 is provided with an outer edge portion, and the outer side of the outer cylinder 7 is provided with a slot 13, and a portion of the outer edge portion is inserted into the slot 13, such as Figure 3 As shown, after the two sets of collecting boxes 9 are installed, they form a complete circle.
