[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] An embodiment provided by the present invention is as follows Figure 1 and Figure 2 As shown, a fixing device for a compaction cylinder of a compactor, as Figure 1 shown, includes a turntable base 1, an outer groove retaining ring 2, an inner groove retaining ring 3, a large compaction cylinder assembly 4, a small compaction cylinder assembly 5, a structure 6 of the compaction cylinder assembly, and a fixing part 7 of the compaction cylinder assembly structure. The large compaction cylinder assembly 4 and the small compaction cylinder assembly 5 are both compaction cylinder assembly structures 6 with the same structure.

[0026] As Figure 3 shown, the surface of the turntable base 1 is provided with a large annular groove 11 and a small annular groove 12. Outer convex teeth 111 are arranged inside the large annular groove 11, and inner convex teeth 121 are arranged inside the small annular groove 12. The bottoms of the large compaction cylinder assembly 4 and the small compaction cylinder assembly 5 are respectively inserted into corresponding positions of the outer convex teeth 111 and the inner convex teeth 121. According to the experimental operation, select one of the specifications of the compaction cylinder and place it on the turntable base 1. When the large compaction cylinder assembly 4 and the small compaction cylinder assembly 5 are respectively fixed in the large annular groove 11 and the small annular groove 12, the bottoms of the large compaction cylinder assembly 4 and the small compaction cylinder assembly 5 respectively correspond to the outer convex teeth 111 and the inner convex teeth 121.

[0027] The turntable base 1 can be installed or disassembled with an outer groove retaining ring 2 and an inner groove retaining ring 3. The outer groove retaining ring 2 and the inner groove retaining ring 3 respectively correspond to and fit into the large annular groove 11 and the small annular groove 12. When they are installed, their tops are on the same plane as the turntable base 1. When using the large compaction cylinder, install the inner groove retaining ring 3 on the turntable base 1 to ensure the flatness of the soil sample at the bottom of the large compaction cylinder; when using the small compaction cylinder, install the outer groove retaining ring 2 on the turntable base 1, which can provide shielding protection and effectively prevent soil foam from flying out during the compaction process and falling into the large annular groove 11, affecting the fixation of the large compaction cylinder during reuse.

[0028] Before using this device, as Figure 4 shown, the compaction cylinder assembly structure 6 includes a bottom cylinder 61, a top cylinder 62 and a silica gel sleeve 63. There are two sets of the bottom cylinder 61 and the top cylinder 62 respectively, and the two sets of bottom cylinders 61 and the two sets of top cylinders 62 are combined into a complete column respectively. The silica gel sleeve 63 runs through the inside of the bottom cylinder 61. As Figure 5 shown, the bottom cylinder 61 further includes a bottom cylinder body 611, a first merging fixing member 613 and a first fixing connecting member 614. The first merging fixing members 613 are arranged at both outer ends of the bottom cylinder body 611, and the first fixing connecting member 614 fixedly connects the corresponding first merging fixing members 613 of the two sets of bottom cylinders 61; as Figure 6 shown, the top cylinder 62 includes a top cylinder body 621, a second merging fixing member 622 and a second fixing connecting member 623. The second merging fixing members 622 are arranged at both outer ends of the top cylinder body 621, and the second fixing connecting member 623 fixedly connects the corresponding second merging fixing members 622 of the two sets of top cylinders 62.

[0029] First, combine the compaction cylinder assembly structure 6 together. First, place the silica gel sleeve 63 between the two sets of bottom cylinders 61, then fix the first merging fixing member 613 and the second merging fixing member 622. The bottom cylinder 61 and the top cylinder 62 are each combined, and then place the top cylinder 62 above the bottom cylinder 61. At this time, the silica gel sleeve top edge 631 provided on the silica gel sleeve 63 is located between the bottom cylinder 61 and the top cylinder 62. The top end of the bottom cylinder body 611 is the upper edge 615 of the bottom cylinder body, and the bottom end of the top cylinder 62 is the lower edge 624 of the top cylinder body. The upper part of the silica gel sleeve top edge 631 coincides with the lower edge 624 of the top cylinder body, and the lower part of the silica gel sleeve top edge 631 coincides with the upper edge 615 of the bottom cylinder body.

[0030] At this time, for the completed combined compaction cylinder assembly structure 6, the outer diameter of the silica gel sleeve 63 is unified with the inner diameter of the top cylinder body 621, the circumferential side of the silica gel sleeve 63 fits with the inside of the top cylinder body 621, and the inner diameter of the silica gel sleeve 63 is unified with the inner diameter of the top cylinder body 621. It can ensure that the diameters of the soil samples inside the top cylinder 62 and the bottom cylinder 61 are the same during the compaction process.

[0031] Next, place the compacting cylinder assembly structure 6 that has been assembled on the turntable base 1. The bottom cylinder 61 includes positioning teeth 612, and the shape of the positioning teeth 612 fits the inner parts of the large annular groove 11 and the small annular groove 12 of the turntable base 1. Thus, the bottom cylinder 61 is limited in position and is not likely to rotate relative to the turntable base 1.

[0032] To ensure that the entire compacting cylinder assembly structure 6 rotates simultaneously with the turntable base 1, as Figure 1 and Figure 6 shown, the top cylinder 62 and the turntable base 1 are fixed by the compacting cylinder assembly structure fixing member 7. The top cylinder 62 also includes a limiting bracket 625, which is arranged on the circumferential side of the top cylinder body 621. The compacting cylinder assembly structure fixing member 7 includes a fixing rod 71 and a limiting connecting member 72. One end of the fixing rod 71 is fixed on the turntable base 1, and the other end passes through the limiting bracket 625 and is fixed above the limiting bracket 625 by the limiting connecting member 72. Rotate and make the limiting connecting member 72 move downward to fix the top cylinder 62 and squeeze the bottom cylinder 61 downward.

[0033] By limiting the position of the bottom cylinder 61, during the rotation of the turntable base 1, it is ensured that the bottom cylinder 61 rotates simultaneously, preventing the bottom of the bottom cylinder 61 from sliding in the chute. At the same time, under the limiting and squeezing state of the compacting cylinder assembly structure fixing member 7, the silica gel sleeve top edge 631 between the top cylinder 62 and the bottom cylinder 61 plays a role in increasing friction to prevent slipping between the top cylinder 62 and the bottom cylinder 61. Neither the turntable base 1 nor the top cylinder 62 at the upper and lower connecting parts of the bottom cylinder 61 will have relative movement with the bottom cylinder 61, thus ensuring that the bottom cylinder 61 rotates at the same speed as the turntable base 1. According to the position trajectory of the falling of the striking hammer during the rotation process, it can be ensured that every part of the soil sample inside the bottom cylinder 61 is evenly struck, improving the accuracy of the experimental data. The function of preventing relative movement of the bottom cylinder 61 in this device has a simple installation step and does not require other fixing methods.

[0034] After the experiment is completed, remove the compacting cylinder assembly structure 6, and the bottom cylinder 61 and the top cylinder 62 can be disassembled. The separable structure of the bottom cylinder body 611 and the top cylinder body 621 is convenient for demolding and taking out the soil sample, replacing the operation steps of the demolding machine, saving workload and improving the test efficiency. Since the silica gel sleeve 63 is made of a flexible material and has a cut in the vertical direction, the silica gel sleeve 63 can be unfolded from this cut to obtain a complete soil sample wrapped by the silica gel sleeve 63, effectively avoiding the adhesion of the soil sample to the inner wall of the compacting cylinder. Thus, the soil sample can be used for soil moisture and density detection, and the water content test of the soil sample can be completed.

[0035] The above are only embodiments of the present utility model, and common knowledge such as specific structures and characteristics known in the solution is not described in detail herein. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
