[0019] An asphalt mixture detection device comprises a base 1, a frame 2 and a storage box 3 installed above the base 1, a detection mechanism installed at the upper end of the frame 2 and a detection box 4 arranged below the detection mechanism, both sides of the frame 2 are provided with discharge ports, and guide plates 5 are installed in the discharge ports, whose two ends correspond to the storage box 3 and the detection box 4 respectively, a placement cavity is provided above the detection box 4, and a recovery cavity is provided below the detection box 4, and the placement cavity and the recovery cavity are separated by a symmetrically installed support plate 6, one end of the support plate 6 is movably connected to the inner wall of the detection box 4, and an electric push rod 7 connected to the support plate 6 is symmetrically installed on the inner wall of the recovery cavity, and a gravity sensor 8 is installed at the bottom of the support plate 6.
[0020] During the inspection, the storage box 3 is opened, and the asphalt mixture inside enters the placement chamber inside the inspection box 4 through the discharge port and the guide plate 5. The weight of the asphalt mixture in the placement chamber is detected by the gravity sensor 8. When the detection amount is reached, the storage box 3 is closed, and no more asphalt mixture is added to the placement chamber. The detection mechanism is started to automatically compact the asphalt mixture in the placement chamber. After the inspection is completed, the electric push rod 7 drives the support plate 6 to rotate downward and open for automatic discharge. The inspected asphalt mixture enters the recovery chamber for recovery, and the electric push rod 7 drives the support plate 6 to rotate upward and return to its original position to prepare for the subsequent inspection of the asphalt mixture. It should be noted that a sealed sliding door is installed on the outside of the recovery chamber to facilitate opening and removing the asphalt mixture.
[0021] The detection mechanism includes a hydraulic cylinder 9 fixedly installed on the top of the frame, a mounting seat 11 connected to the output end of the hydraulic cylinder 9, and a compaction roller 10 slidably installed on the mounting seat. A slide groove is opened below the mounting seat 11, and a screw rod is rotatably installed inside the slide groove. A slider is spirally connected to the outer side of the screw rod. The compaction roller 10 is installed below the slider. The height of the compaction roller 10 is adjusted by the hydraulic cylinder 9 so that its bottom is in contact with the asphalt mixture inside the placement cavity. The position of the compaction roller 10 left and right is adjusted by the screw rod slider, so that the asphalt mixture inside the placement cavity is automatically compacted.
[0022] A buffer groove is provided on the side wall of the frame 2, and both ends of the mounting seat 11 are slidably connected to the buffer groove through limit blocks. When the hydraulic cylinder 9 is used to adjust the height of the compacting roller 10, the limit blocks will be driven to move in the buffer groove to play a role of limit buffering.
