[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This utility model provides an automatic slab-type asphalt concrete specimen compaction instrument, such as... Figure 1-3 As shown, it includes: a support structure, including a pressure seat 1 and a support frame 2 connected to the pressure seat 1, with protective enclosures 3 arranged around the upper part of the support frame 2, and the test mold 26 placed on the pressure seat 1; a compaction unit, including an electromagnetic chuck 4, a compaction hammer, and a guide device, with the bottom surface of the electromagnetic chuck 4 fixedly connected to the guide device, the compaction hammer including a rectangular compaction plate 5 and a magnetic moving part 6, the rectangular compaction plate 5 being fixedly connected to the magnetic moving part 6 via a connecting rod 7, the magnetic moving part 6 being slidably connected to the guide device, and the electromagnetic chuck 4 and the magnetic moving part 6 being magnetically attracted; a moving component, the moving component being installed on the support frame 2, connected to the compaction unit, and capable of driving the compaction unit to move; and a controller, the controller being connected to the electromagnetic chuck 4 and capable of controlling the electromagnetic chuck 4 to turn on and off, and the controller being signal-connected to the moving component. When the electromagnetic chuck 4 is energized, the magnetic moving part 6 moves the rectangular compaction plate 5 toward the electromagnetic block through the magnetic attraction between it and the electromagnetic block, thereby raising the compaction hammer. When the electromagnetic chuck 4 is de-energized, the magnetic moving part 6 falls freely under the action of gravity, thus hammering the mold 26. The moving component drives the compaction unit to move, which can reduce the workload of operators, reduce safety hazards, greatly shorten the test cycle, and improve work efficiency. It can quickly and with high quality complete the slab asphalt concrete molding test. The number of times the electromagnetic chuck 4 is energized and de-energized can be controlled by the controller, and the number of times the compaction hammer is used can be set. The operation is convenient and quick, and it is convenient to carry out compaction tests on molded specimens with different requirements.

[0028] In a further preferred embodiment of this utility model, the guiding device includes a limiting ring plate 8 and four connecting posts 9. One end of each connecting post 9 is fixedly connected to the limiting ring plate 8, and the other end is fixedly connected to the electromagnetic chuck 4.

Four sliders 11 are arranged around the circumference of the magnetic moving part 6, and are slidably connected to the grooves 10 via the sliders 11. The guiding device also includes four insulating arc-shaped side plates 12. An insulating arc-shaped side plate 12 is fixedly connected between two connecting posts 9. The four insulating arc-shaped side plates 12 and the four connecting posts 9 form a side-closed magnetic shielding cavity. The magnetic shielding cavity prevents external impurities from being attracted to the electromagnetic chuck 4 under magnetic attraction. The hammer can slide within the magnetic shielding cavity, and the rectangular hammering plate 5 can pass through the central hole of the limiting ring plate 8. The limiting ring plate 8 prevents the magnetic moving part 6 from sliding out of the magnetic shielding cavity.

The automatic slab-type asphalt concrete specimen compactor can use the existing rotating component 17 with a 90° rotation. The rotating plate rotates 90°, which can drive the rectangular compaction plate 5 to rotate 90°. That is, the rectangular compaction plate 5 hammers the specimen mold 26 in two directions, making the specimen mold 26 more uniformly stressed and reducing the porosity of the specimen mold 26.

[0032] In a further preferred embodiment of this invention, the upper surface and side surfaces of the electromagnetic chuck 4 are coated with an insulating layer, the insulating layer being made of silver.

The left-moving button 22 and the right-moving button 23 are used to control the compaction unit to move a certain distance to the left and right, respectively. The forward-moving button 24 and the backward-moving button 25 are used to control the compaction unit to move a certain distance forward and backward, respectively. The control display screen 18 also allows setting the number of times the electromagnetic energizes, thus determining the number of times the compaction hammer will strike.

[0034] The method of using the automatic slab-type asphalt concrete specimen compactor of this utility model is as follows: First, pour the asphalt mixture into the specimen mold 26. Then, turn on the power switch 19 to power on the entire device. Next, use the buttons on the control display screen 18 to move the compaction hammer to the designated position.
