Then, the driving motor 136 is started to drive the transmission gear 141 to rotate, namely, the spline long shaft 111 is driven to rotate, so that the drill bit 112 rotates, then, the feeding motor 137 is started to drive the feeding screw rod 133 to rotate, under the action of the auxiliary sliding plate 134 and the feeding sliding plate 138, the spline long shaft 111 moves in a direction far away from the feeding motor 137, namely, the feeding of the drill bit 112 is realized, namely, the sampling of a wall body is realized, dust generated by the drill bit 112 cannot overflow due to the contact between the end face of the collecting cylinder 110 and the wall, sampling products generated by the drill bit 112 enter the collecting cylinder 110, and enter the storage chamber 114 below along the trapezoid funnel 131 and the feeding square tube 113, so that the automatic storage of sampling samples is realized, and under the action of the cam 123, the annular storage disc 109 is in a vibration state during sampling, so that the vibration leveling of the samples in the storage chamber 114 is realized, and the influence of the sample stacking in the storage chamber 114 on the subsequent samples is avoided.
After the drilling of the drill bit 112 is completed, the feeding motor 137 is started to drive the feeding screw rod 133 to reversely rotate, namely, the drill bit 112 moves towards the direction close to the feeding motor 137, the residues in the wall sampling holes are pushed into the collecting cylinder 110 under the action of the drill bit 112, and after the sampling is completed, the trapezoidal pressing block 121 returns to the initial position, namely, the corresponding sector-shaped cover plate 116 of the storage cavity 114 covers the storage cavity 114 again.
And repeating the steps to realize continuous sampling of the wall body.
When the sample in the storage chamber 114 needs to be taken out, the storage chamber 114 storing the sample to be taken is moved to a position farthest from the square feeding tube 113, then a collecting cylinder is placed below the storage chamber 114, and then the auxiliary motor 126 is started to drive the trapezoidal pressing block 121 to move upwards, so that the fan-shaped cover plate 116 below the storage chamber 114 moves in a direction away from the axis of the annular storage disc 109, and the sample in the storage chamber 114 falls into the collecting cylinder below.
When the drill bit 112 needs to be replaced, the feeding motor 137 is started to drive the auxiliary sliding plate 134 to move towards the direction approaching to the feeding motor 137, so that the end face of the circular scraping plate 132 and the collecting cylinder 110 are on the same plane, namely, the drill bit 112 is located on the outer side of the collecting cylinder 110, the drill bit 112 is convenient to replace, and in the process that the circular scraping plate 132 moves relative to the collecting cylinder 110, the circular scraping plate 132 scrapes and cleans the inner wall of the collecting cylinder 110.
