The specific contents are as follows:

[0020] 1. Limiting components are symmetrically arranged at the bottom of both sides of the support frame. When testing and sampling the road surface, the movable plate is driven downward by the hydraulic push rod, so that the sampling tube leaks out of the sampling slot, the driving motor is started to drive the sampling tube to rotate, and the hydraulic push rod is moved downward, and sampling can be carried out through the sampling tube. When sampling, the sample enters the inside of the sampling tube and can push the top plate to rise. After sampling, the sampling tube can be properly rotated so that the connecting plate and the U-shaped plate are in the same straight line, and the U-shaped frame is pushed to drive the U-shaped plate to move, and the U-shaped plate moves. Then, the first magnet block and the second magnet block are attracted to each other, so that the U-shaped plate is limited, and then the sampling tube is driven to move upward by the hydraulic push rod, so that the connecting plate moves upward, and the connecting block can be inserted into the connecting groove, so that the mounting plate and the connecting plate are abutted, and then when the sampling tube moves upward, the top plate is limited and the sample can be ejected without disassembling the sampling tube.

[0021] 2. Before pushing the U-shaped plate to move, hold the U-shaped frame and pull the movable plate to move, thereby driving the movable rod to move and stretch the telescopic spring. After the movable rod moves, pull the connecting rod to rotate. After the connecting rod rotates, it drives the positioning rod to move upward. While the positioning rod moves, it drives the support block to slide on the support rod, and limits the movement of the positioning rod, so that the positioning rod leaves the positioning groove on the fixed seat, so that the U-shaped plate loses the limit and can move. After sampling is completed, the U-shaped plate is reset so that the positioning rod is inserted into the positioning groove, and then the U-shaped plate can be positioned during the subsequent sampling process to avoid vibration during the sampling process causing the U-shaped plate to shift, and to avoid continuous shaking of the U-shaped plate during the sampling process to avoid affecting the downward movement of the sampling tube.

[0032] Working principle: Before using this kind of sampling equipment for engineering inspection, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, the limit assemblies 2 are symmetrically arranged at the lower sides of the support frame 1. When the road surface is inspected and sampled, the movable plate 103 is driven downward by the hydraulic push rod 102, so that the sampling tube 107 leaks out of the sampling slot, the driving motor 106 is started to drive the sampling tube 107 to rotate, and the hydraulic push rod 102 is moved downward, and sampling can be carried out through the sampling tube 107. When sampling, the sample enters the interior of the sampling tube 107 and can push the top plate 109 to rise. After the sampling is completed, the sampling tube 107 can be properly rotated so that the connecting plate 111 and the U-shaped plate 201 are in the same straight line, and the U-shaped frame 206 is pushed to drive the U-shaped plate 201 to move, and the U-shaped plate 201 moves.

Then, if the sampling tube 107 moves up, the top plate 109 is limited and the sample can be ejected without disassembling the sampling tube 107. Through the limiting component 2, after sampling the road, it is convenient to take out the sample inside the sampling tube 107 without disassembling the sampling tube 107, thereby improving convenience and practicality;

[0033] Before pushing the U-shaped plate 201 to move, hold the U-shaped frame 206 to pull the movable plate 207 to move, thereby driving the movable rod 208 to move and stretch the telescopic spring 210. After the movable rod 208 moves, it pulls the connecting rod 212 to rotate. After the connecting rod 212 rotates, it drives the positioning rod 213 to move up. While the positioning rod 213 moves, it drives the supporting block 214 to slide on the supporting rod 215, and limits the movement of the positioning rod 213, so that the positioning rod 213 leaves the positioning groove 217 on the fixed seat 216, so that the U-shaped plate 201 loses the limit and can move. After the sampling is completed, the U-shaped plate 201 is reset so that the positioning rod 213 is inserted into the positioning groove 217, and then the U-shaped plate 201 can be positioned in the subsequent sampling process to avoid vibration during the sampling process causing the U-shaped plate 201 to shift, and to avoid the U-shaped plate 201 shaking continuously during the sampling process to avoid affecting the downward movement of the sampling tube 107.
