DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings. Example 1

[0034] A rock and soil compaction device for geotechnical engineering, such as Figure 1-Figure 5 As shown, it includes a tamping box 1, a receiving plate 2, a connecting beam 3, a bracket 4, a moving mechanism, a power mechanism and a shock-absorbing mechanism. A receiving plate 2 is welded on the top of the tamping box 1. The tamping box 1 is used to load the power mechanism and the shock-absorbing mechanism of the tamping components. Connecting beams 3 are welded on the left and right sides of the bottom of the receiving plate 2. The connecting beams 3 on both sides are fixed with brackets 4 on the sides away from each other. A moving mechanism for the device to move is provided on the bracket 4. A power mechanism for tamping and a shock-absorbing mechanism for preventing damage to the device are provided in the tamping box 1.

[0035] like Figure 2-Figure 4As shown, the moving mechanism includes a first connecting shaft 41, a second connecting shaft 42, an electric roller 43, a gear 44 and a crawler track 45. Three second connecting shafts 42 are evenly spaced and connected to the brackets 4 on both sides. The first connecting shaft 41 is fixedly connected to the side of the connecting beams 3 on both sides that are away from each other. The first connecting shaft 41 is rotatably connected to the electric roller 43, and the electric roller 43 has teeth. The second connecting shaft 42 is rotatably connected to the gear 44, and the gear 44 is engaged with the teeth of the electric roller 43. The electric roller 43 drives the gear 44 to rotate. A crawler track 45 is placed between the three gears 44 on the same side. The crawler track 45 has teeth, and the teeth of the crawler track 45 are engaged with the gear 44. The rotation of the gear 44 drives the crawler track 45 to rotate and travel on the ground.

[0036] like Figure 5-Figure 8 As shown, the power mechanism includes a connecting frame 51, a transmission motor 52, a rotating disk 53, a connecting block 54 and a first transmission plate 55. The top of the tamping box 1 is connected to the connecting frame 51, the bottom of the connecting frame 51 is connected to the transmission motor 52, the output shaft of the transmission motor 52 is connected to the rotating disk 53, the transmission motor 52 is used to drive the rotating disk 53 to rotate, the rotating disk 53 is hinged with a connecting block 54, the lower part of the connecting block 54 is hinged with the first transmission plate 55, and the rotation of the rotating disk 53 drives the connecting block 54 and the first transmission plate 55 to move up and down.

[0037] like Figure 6-Figure 8 As shown, the shock absorbing mechanism includes a sliding column 56, a first spring 57, a second transmission plate 58, a second spring 59 and a tamping member 510. Two sliding columns 56 are connected to the bottom of the first transmission plate 55. The second transmission plate 58 is slidingly connected between the two sliding columns 56. A first spring 57 is connected between the first transmission plate 55 and the second transmission plate 58. A second spring 59 is connected between the second transmission plate 58 and the sliding column 56. The first spring 57 and the second spring 59 are used for buffering and shock absorption. A tamping member 510 is connected to the bottom of the second transmission plate 58. The downward movement of the first transmission plate 55 will drive the first spring 57, the second transmission plate 58, the second spring 59 and the tamping member 510 to move downward, and the tamping member 510 moves downward to compact the ground.

[0038] When the rock and soil compacting device is needed, the electric roller 43 is started, the electric roller 43 drives the gear 44 to rotate, and the rotation of the gear 44 drives the crawler 45 to rotate so that the device can travel. After the rock and soil compacting device is driven to the ground that needs to be compacted, the output shaft of the transmission motor 52 is started to rotate to drive the rotating disk 53 to rotate. The rotation of the rotating disk 53 drives the connecting block 54 and the first transmission plate 55 to move up and down. The downward movement of the first transmission plate 55 drives the first spring 57, the second transmission plate 58, the second spring 59 and the compacting member 510 to move downward. The compacting member 510 moves downward to compact the ground. When the compacting member 510 contacts the ground, the first spring 57 The first spring 57 and the second spring 59 are compressed, and the sliding column 56 slides on the second transmission plate 58 to stretch the second spring 59. After the tamping piece 510 is in contact with the ground, the first transmission plate 55 moves upward. The upward movement of the first transmission plate 55 drives the first spring 57, the second transmission plate 58, the second spring 59 and the tamping piece 510 to move upward. The first spring 57 and the second spring 59 return to their original state. The tamping piece 510 repeatedly moves up and down to tamp the ground. The first spring 57 and the second spring 59 enable the tamping piece 510 to move upward for a distance after contacting the ground. When encountering harder rocks, there is a certain buffer distance, which can play a shock-absorbing effect and prevent damage to the device. Example 2

[0039] On the basis of Example 1, Figure 1 、 Figure 5 、 Figure 9 、 Figure 10 and Figure 11 As shown, it also includes a dual-axis motor 6, a loading shaft 61, a connecting frame 611, a steel rope 66 and a bolt 8. The dual-axis motor 6 is connected to the top of the connecting plate 2, and the loading shafts 61 are installed on the output shafts on both sides of the dual-axis motor 6. The dual-axis motor 6 is used to drive the loading shafts 61 to rotate. The left and right sides of the top of the connecting plate 2 are connected to the connecting frames 611. The two connecting frames 611 are respectively located on both sides of the dual-axis motor 6. A steel rope 66 is wound around the loading shaft 61. The two ends of the steel rope 66 pass through the front and rear sides of the connecting frame 611 respectively, and the ends of the two ends of the steel rope 66 are connected to bolts 8. The surface of the bolt 8 is provided with a thread. Inserting the bolt 8 into the ground makes the steel rope 66 taut.

[0040] When the device compacts the ground, the two ends of the steel rope 66 can be fixed to the ground by bolts 8, and then the dual-axis motor 6 is started. The output shafts on both sides of the dual-axis motor 6 rotate to drive the loading shaft 61 to rotate. The loading shaft 61 rotates to roll up the steel ropes 66 on both sides. After the steel ropes 66 on both sides are tightened, they will give the device a downward pulling force, so that the device can further compact the ground.

[0041] like Figure 9-10As shown, it also includes a screw 62, a worm wheel 63, a turntable 64, a worm 65 and a pulley 67. The worm 65 is rotatably connected to the connecting beams 3 on both the left and right sides. The turntable 64 is welded to the front end of the worm 65. The worm wheels 63 are rotatably connected to the front and rear sides of the connecting beam 3. The worm wheel 63 is engaged with the worm 65. The screw 62 is connected to the worm wheel 63 through a thread. The upper side of the front screw 62 is rotatably connected to the pulley 67. The front part of the steel rope 66 is in contact with the pulley 67, and the rear part of the steel rope 66 passes through the screw 62.

[0042] When the steel rope 66 is tightened, the turntable 64 can be rotated. The rotation of the turntable 64 drives the worm 65 to rotate. The rotation of the worm 65 drives the worm wheel 63 to rotate. The rotation of the worm wheel 63 drives the screw 62 and the pulley 67 to move upward through the thread. The upward movement of the pulley 67 supports the taut steel rope 66 upward, making the steel rope 66 tighter, giving the device a greater downward pressure, and further compacting the ground.

[0043] like Figure 9 、 Figure 10 and Figure 12 As shown, it also includes a water tank 7, a spherical plug 71 and a third spring 72. The top of the screw 62 is connected to the water tank 7. A notch is opened at the bottom of the water tank 7. The spherical plug 71 is slidably connected to the notch at the bottom of the water tank 7. The spherical plug 71 blocks the notch at the bottom of the water tank 7. A third spring 72 is connected between the spherical plug 71 and the water tank 7. The spherical plug 71 is located above the steel rope 66. After the water in the water tank 7 flows out, it will drip onto the steel rope 66.

[0044] When the tamping member 510 of the device hits the ground, it will vibrate. The vibration of the device causes the spherical plug 71 to vibrate on the water tank 7. When the spherical plug 71 vibrates, it will separate from the water tank 7 to create a certain gap, and the water in the water tank 7 will flow out. At this time, the third spring 72 is stretched. When one vibration is over, the elastic force of the third spring 72 causes the spherical plug 71 to return to its original position. Each time the water in the water tank 7 vibrates, the water will flow out and drip onto the steel rope 66. The vibration of the steel rope 66 will scatter the water droplets to form water mist, which has a dust reduction effect.

[0045] like Figure 11 、 Figure 13 and 14 As shown, a screw bolt 81 is also included. The screw bolt 81 is connected to the bolt 8 through a thread. Connecting the screw bolt 81 to the bolt 8 makes it easier for the bolt 8 to be inserted into the ground. When the steel rope 66 is tightened, the bolt 8 is subjected to tension, which drives the screw bolt 81 to contact the ground more tightly.

[0046] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
