DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-11 The present invention provides a technical solution: a method for sampling for road engineering, which specifically comprises the following steps: Step 1: Select the area and use the roller to move the device to the sampling area; Step 2: Sample drilling: the cooperation of the mounting plate 2, the servo motor 3 and the electric telescopic rod 5 causes the sampling tube 6 to perform sample drilling, and after drilling to a preset depth, the sample is intercepted by the pre-interception mechanism 7; The servo motor 3 is started to drive the rotating shaft 4 and the sampling tube 6 to rotate, and the sampling tube 6 synchronously drives the drill rod 701 to rotate and drill, and then the electric telescopic rod 5 is started, so that the extended end of the electric telescopic rod 5 drives the mounting plate 2, the servo motor 3, the rotating shaft 4, the sampling tube 6 and the drill rod 701 to slowly move downward for drilling. When the sampling tube 6 drills to a preset depth, the sample column will form a hollow sample column; Step 3: dust-proof and isolation: the sampling tube 6 takes samples and drives the dust-proof temporary storage mechanism 8 to move in sync, and the dust-proof temporary storage mechanism 8 isolates and temporarily stores the drilled floating dust; During the period when the mounting plate 2 drives the rotating shaft 4 and the sampling tube 6 to move downward, the rotating shaft 801 is synchronously driven downward, and the rotating shaft 801 drives the extrusion sleeve 808 to contact the ground through the inner polygonal sleeve 802 and the ring frame 805, and as the rotating shaft 4 continues to move downward, the inner polygonal sleeve 802 after the locking position will be elastically compressed with the rotating shaft 801. During the drilling process of the sampling tube 6 driven by the rotating shaft 4, the rotating shaft 4 will drive the rotating shaft 801 and the inner polygonal sleeve 802 to rotate through the transmission cooperation of the pulley 812 and the belt 813, and the inner polygonal sleeve 802 drives the first gear 809 to rotate, and the first gear 809 is synchronously meshed with the second gear 810, so as to cause the ring frame 805, the shielding ring plate 806, the conical disk 807 and the temporary storage box 811 to rotate. During the rotation of the conical disk 807, the soil and ash thrown out of the interlayer of the extrusion sleeve 808 and the sampling tube 6 will be taken over, and the soil and ash will be transferred to the temporary storage box 811 for temporary storage through centrifugal shaking; Step 4: Automatic interception: After the sampling tube 6 and the dustproof temporary storage mechanism 8 are moved to the preset position, the automatic interception mechanism 9 is synchronously driven to automatically control the pre-interception mechanism 7, so as to automatically intercept the root of the sample; When the mounting plate 2 drives the rotating shaft 4, the sampling tube 6 and the rotating shaft 801 to move downward to the preset position, the sampling tube 6 synchronously drives the annular groove plate 707 to descend to the highest point inclined surface of the horizontal push plate 908, and the rotating shaft 801 descends and synchronously drives the paddle 906 to enter the interior of the threaded tube 902, and causes the paddle 906 to form a surrounding conflicting fit with the baffle 904 inside the threaded tube 902, and the rotating shaft 801 rotates and synchronously drives the paddle 906 to rotate, and the paddle 906 drives the threaded tube 902 to rotate by conflicting with the baffle 904, and the threaded tube 902 rotates, and the threaded sleeve 907 on the surface of the threaded tube 902 drives the step push block 909 to rise, and the step push block 909 slowly rises and slowly drives the horizontal push plate 908 to advance intermittently; The intermittent lateral advancement of the horizontal push plate 908 will intermittently squeeze the annular groove plate 707, and the annular groove plate 707 is forced to drive the vertical rod 706 to descend, and the vertical rod 706 descends to drive the first push plate 703 and the second push plate 705 to move downward, and the first push plate 703 and the second push plate 705 move downward, respectively and synchronously pressing the first intercepting blade head 702 and the second push plate 705 to move relative to each other, and with the intermittent relative movement of the first intercepting blade head 702 and the second push plate 705, the root of the sample column is cut and intercepted; After sampling is completed, the automatic intercepting mechanism 9, the pre-intercepting mechanism 7 and the dust-proof temporary storage mechanism 8 are reset in sequence. The second intercepting knife head 704 and the first intercepting knife head 702 in the pre-intercepting mechanism 7 are held by gravity and will not be reset as a whole along with the pre-intercepting mechanism 7. After the device is raised as a whole, the operator pushes the sample column from bottom to top, which can cause the sample column to be disengaged from the top of the first intercepting knife head 702 and the second intercepting knife head 704. After the first intercepting knife head 702 and the second intercepting knife head 704 retract, the sample column falls off accordingly.
