Figure 1-3 The sampling device includes a support base 1, a load-bearing frame 2, a rotary motor 3, a driving gear disk 4, a driven gear disk 5, a driven vertical shaft 6, a hydraulic cylinder 7, a crossbeam 8, a guide rack 9, a drive gear 10, a hydraulic station 11, a sampling fixture 12, a sampler 13, and an inclined support 14, wherein: Support base 1 is used to support the overall weight of the upper part; The load-bearing frame 2 is fixed on the support base 1 and bears the shear weight of the sampling device; Rotary motor 3 is the power source for the horizontal rotation of crossbeam 8, and is connected to drive gear disk 4 below; The drive gear disk 4 is connected to the rotary motor 3 at the top and meshes with the driven gear disk 5 on the side, which can drive the driven gear disk 5 to rotate; The driven gear disk 5 is fixed on the driven vertical shaft 6; The driven vertical shaft 6 is welded together with the crossbeam 8. The horizontal rotation of the driven gear 5 can synchronously drive the horizontal rotation of the crossbeam 8 to align with the sampling vehicle. The hydraulic cylinder 7 can be used by the hydraulic station 11 to complete the up-down lifting and positioning of the sampler 13; The crossbeam 8 supports the whole vehicle sampling device for raw and auxiliary materials, and is welded with the diagonal support 14 between the crossbeam and the supporting frame 2 to form a stable triangular structure. Multiple longitudinally arranged reinforcing beams are welded between the diagonal support 14 and the crossbeam 8. The guide rack 9 includes a rack and a guide rail. The rack is fitted onto the guide rail of the crossbeam 8 to form the guide rack 9. Its function is to assist the drive gear 10 to move linearly along the rack and to locate the sampling point.

After reaching the position, the lower rotating rod 13-2 is fixed. The upper rotating rod 13-1 of the sampler is manually rotated, and the inner cylinder wall 13-4 of the sampler is rotated to close, thus completing the opening and closing sampling action of the sampling hole 13-5. After sampling, the sample is poured into the sample bag. The hydraulic cylinder 7 lifting mechanism is raised again by remote control to reach the designated position. (6) Replace the sampler, and then continue to perform steps 2-6 until the whole vehicle sampling is completed; (7) Move the horizontal beam 8 horizontally by remote control, move the device to the safe position to be sampled, remove the remote control safety to ensure safety and prevent misoperation.
