Placing the test molds 4 filled with the dry mixed mortar into the inner cavity of the compaction table top 3, wherein each test mold 4 approximately corresponds to the corresponding fixing rod 11 (without a very accurate placement position, basically, a person skilled in the art can complete the operation by means of naked eyes), starting the lifting cylinder 8, shortening the cylinder rod of the lifting cylinder 8 and driving the cross beam 6 to move downwards, and synchronously moving the floating beam 5 and the fixing rod 11 downwards during the downward movement of the cross beam 6, wherein the elastic propping force of the reset spring 16 to the locking nut 17 is applied, the floating beam 5 drives the connecting ring 10 to move downwards, so that the connecting ring 10 drives the hinge rod 18 to swing, and the fan-shaped plates 7 swing downwards around the axial direction of the pivot when the hinge rod 18 swings, and the maximum diameter size of the forward projection areas of the four fan-shaped plates 7 on the fixing rod 11 is far smaller than the inner diameter size of the test mold 4;
As the cross beam 6 continues to move downwards, the sector plate 7 will also enter the test die 4 (the upper layer of dry mixed mortar in the test die 4 is positioned below the top surface of the test die 4, or the dry mixed mortar is not completely filled with the test die 4), when the end part of the stop bolt 13 contacts the top of the vibrating table 3, the floating beam 5 cannot continue to move downwards, the floating beam 5 and the vibrating table 3 are in a relatively static state, as the cross beam 6 continues to move downwards, the fixed rod 11 also continues to move downwards, so that the sector plate 7 moves downwards relative to the connecting ring 10, at the moment, the hinge rod 18 will pull the sector plate 7 upwards, so that the sector plate 7 upwards overturns, the arc-shaped periphery of the sector plate 7 has extrusion acting force on the inner cavity wall of the test die 4, and as the four sector plates 7 are arranged on the fixed rod 11 in an array, a centering effect is generated on the test die 4, so that the test die 4 and the bottom of the test die 4 does not need to slide on the inner cavity bottom wall of the vibrating table 3, so that the test die 4 and the fixed rod 11 are coaxially positioned, and thus the sector plate 7 is placed in the test die 4 can be positioned in the accurate position after the test die 4 is placed in the test die 4, and the test die 4 is turned to be positioned in a relatively simple and convenient mode;
After the fan-shaped plate 7 is turned to a horizontal state, the bottom surface of the disc-shaped structure spliced by the fan-shaped plate 7 is longitudinally spaced from the upper layer of the dry mixed mortar in the test die 4, the vibration motor 9 is started at the moment, the vibration force generated by the vibration motor 9 is transmitted to the vibration table top 3, the test die 4 is subjected to vibration force, so that the dry mixed mortar in the test die 4 is compacted under the action of the vibration force, the dry mixed mortar in the upper layer of the inner cavity of the test die 4 is blocked by the disc-shaped structure spliced by the fan-shaped plate 7 and does not generate splashing, in addition, when the vibration amplitude is large, the test die 4 can move upwards relative to the vibration table top 3, at the moment, the dry mixed mortar in the upper layer of the inner cavity of the test die 4 also moves upwards along with the test die 4, and is extruded by the bottom of the structure, and the dry mixed mortar in the upper layer can be pressed into the dry mixed mortar in the inner cavity of the test die 4, the effect of the dry mixed mortar can be improved to a certain extent, meanwhile, the dry mixed mortar in the vibration is prevented from being excessively large in amplitude, the vibration amplitude of the test die 4 is blocked by the disc-shaped structure, and the dry mixed mortar in the gap is extruded in the water gap (the gap is formed by the water gap between the water and the water gap 20 in the water tank and the water gap in the water tank in the process;
After the compaction is finished, the staff cleans the liquid in the water storage tank 19 firstly, for example, dry rags are used for adsorbing the liquid (the liquid amount is less), then the lifting cylinder 8 is started, the cylinder rod of the lifting cylinder 8 stretches and drives the cross beam 6 to move upwards, and then the floating beam 5 can be driven to move upwards, so that the fixing rod 11 and the sector plate 7 move upwards and are separated from the test die 4, after the fixing rod is separated from the sector plate, the sector plate 7 is driven to overturn downwards by the hinge rod 18, and after the sector plate 7 is far away from the test die 4, the staff takes down the test die 4 on the compaction table surface 3, and then one compaction operation is completed.
The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
