Through the combined action of the fixed pipe 8 and the connecting pipe 9, the outside air is wrapped with dust and enters the air intake box 10, thereby achieving the goal of sucking the dust generated during the work into the air intake box 10, avoiding the situation of excessive dust in the working environment, preventing the dust from being inhaled by the staff, and protecting the health of the staff.

[0021] The inner cavity of the air inlet box 10 is plugged with a filter 29, which is in an "L" shape. The opening direction of the air inlet box 10 is tilted downward. The filter 29 is arranged in an "L" shape, which can be easily installed and removed, so as to clean the dust on the filter 29, and the opening direction of the air intake box 10 is arranged downward, which can better absorb dust.

[0022] There are two groups of fan blades 7, which are symmetrically arranged front to back about the center of the fixed box 5, and the two groups of fan blades 7 are located in the fixed box 5; Providing two sets of symmetrical fan blades 7 can ensure that the air entering the fixing box 5 flows to the front and rear sides, ensuring normal air intake.

[0023] The front and rear ends of the rotating shaft 6 are fixedly installed with locking rings 12, the side close to the fixed box 5 of the eccentric block 11 is fixedly installed with an extension ring 28, the top end of the flat plate 1 is fixedly installed with a positioning frame 15, the surface of the positioning frame 15 is sleeved with a spring 16, the middle part of the positioning frame 15 is movably sleeved with a locking block 13, the bottom end of the side close to the fixed box 5 of the locking block 13 is fixedly installed with a push block 14, the bottom end of the fixed box 5 is fixedly installed with an extension pipe 17, the bottom end of the extension pipe 17 is fixedly installed with a connecting box 18, the inner cavity of the connecting box 18 is slidably connected with a push frame 19, the bottom end of the push frame 19 is fixedly installed with a top block 20, and the top end of the top block 20 and the top end of the inner cavity of the connecting box 18 are fixedly installed with a spring 21.

[0024] The top end of the locking block 13 is clamped between the middle part of the locking ring 12 and the eccentric block 11 and the connecting box 18, the eccentric block 11 is located on the side, away from the fixed box 5, of the transmission wheel 3, and the locking block 13 is divided into two groups which are symmetrical about the axis of the rotating shaft 6. By setting the separate locking block 13, the locking block 13 can lock and position the eccentric block 11 and the rotating shaft 6, so that the eccentric block 11 is prevented from falling off due to the inclination of the device during tamping.

[0025] The bottom surface of the push frame 19 and the top surface of the push block 14 are inclined surfaces, and the push frame 19 and the push block 14 are attached. The push frame 19 and the push block 14 are set to be inclined surfaces, so that when the push frame 19 moves downwards, the push block 14 is pushed out by the inclined surface, so that the locking block 13 can normally unlock the eccentric block 11.

By pulling out the switching shaft 25 to the left to expose the insertion hole 26, using the right end of the switching shaft 25 to close the connecting pipe 9, and then inserting the water pipe into the insertion hole 26, the device can suck water into the fixed box 5, and the water is sprayed out through the air outlet pipe 24. At this time, the air outlet pipe 24 is taken off from the fixed frame, and then the operator controls the water outlet direction, so that the device can be cleaned, and the maintenance of the device is more convenient.

[0027] The bottom surface of the top block 20 is an inclined surface, the extension tube 17 is connected to the connection box 18, the top block 20 completely blocks the bottom tube 22, and the top block 20 cannot completely block the bottom end of the extension tube 17; It is ensured that air or water can enter the connection box 18, and the connection box 18 will not be lifted until air or water accumulates to a certain extent in the connection box 18.

[0028] The left end of the fixed tube 8 is movably connected to a switching shaft 25. A plug hole 26 is provided at the top of the switching shaft 25. Communication holes 27 are provided on the front and rear sides of the switching shaft 25. The communication holes 27 are connected to the connecting tube 9. By setting a switching shaft 25, the pulling out and inserting of the switching shaft 25 can control the suction of air and water, thereby realizing the switching of states. A slider is provided at the bottom end of the switching shaft 25, and a slide groove is provided at the bottom end of the inner cavity of the fixed tube 8 to ensure that the switching shaft 25 cannot rotate in the fixed tube 8, thereby ensuring that the fixed tube 8 and the connecting tube 9 can be correctly connected.

[0029] Among them, the top of the outlet pipe 24 is inclined, the outlet pipe 24 is a stainless steel bellows, the top of the junction box 23 is fixedly installed with a fixing frame, and the top of the outlet pipe 24 is plugged into the fixing frame; A fixing frame is provided for placing the air outlet pipe 24 to achieve heat dissipation for the engine 2, and the air outlet pipe 24 of the stainless steel bellows can be bent freely for cleaning operations.

[0030] Working principle and usage process: When in use, start the engine 2, the engine 2 drives the rotating shaft 6 to rotate through the transmission wheel 3 and the transmission belt 4. The rotating shaft 6 drives the fan blades 7 and the eccentric weight 11 to rotate when rotating. At this time, step on the bottom end of the flat plate 1 by your foot to make the flat plate 1 fit the ground. The rotation of the fan blades 7 generates suction, and the outside air is drawn into the fixed box 5. In the process of drawing air, the outside air enters the air intake box 10, is filtered through the filter screen 29, and the filtered air enters the fixed box 5, and enters the connecting box 18 through the fixed box 5 and the extension tube 17, so that the pressure in the connecting box 18 is continuously increased, thereby pushing the top block 20 upward to drive the pushing frame 19 to move upward. At this time, the pushing block 14 that has lost the support of the pushing frame 19 drives the locking block 13 to move toward the rotating shaft 6 under the elastic action of the compressed spring 16, thereby making the top end of the locking block 13 stuck in the gap between the locking ring 12 and the eccentric weight 11 and the extension ring 28, locking the eccentric weight 11 on the rotating shaft 6 for positioning; During this process, since the device cannot move, the rotating shaft 6 is in a balanced state and the eccentric mass 11 is not subjected to lateral forces. Therefore, the eccentric mass 11 will not be separated from the shaft 6 during rotation, and the locking process is completed within five seconds. The operator then removes his foot and pushes the device forward on the work surface, whereby the rotation of the eccentric mass 11 generates vibrations, which in turn perform the compaction operation; After the top block 20 is moved upward, the bottom pipe 22 can be connected to the connection box 18. At this time, air enters the bottom pipe 22, is discharged through the junction box 23 and the outlet pipe 24, and sprays on the engine 2 to provide air cooling and auxiliary heat dissipation for the engine 2. When the work is finished, the switching shaft 25 is pulled to the left a certain distance so that the plug hole 26 extends out of the fixed pipe 8, and the water pipe is inserted into the plug hole 26. At this time, the communicating hole 27 and the connecting pipe 9 are staggered, and the switching shaft 25 closes the connecting pipe 9. At this time, the fan blades 7 draw water into the fixed box 5, through the fixed box 5, the extension pipe 17, the connecting box 18, the bottom pipe 22 and the junction box 23, and finally sprayed out from the outlet pipe 24. The top end of the outlet pipe 24 is removed from the fixed frame to achieve flushing of the device; After the device is shut down, the rotating shaft 6 no longer rotates, and the connecting box 18 loses the injection of air or water. The spring 21 in the compressed state pushes the top block 20 downward under the action of elasticity, and then pulls the push frame 19 downward, pushing the two push blocks 14 apart, so that the locking block 13 stops locking the eccentric block 11. At this time, the eccentric block 11 can be directly removed, and the eccentric blocks 11 of different weights or lengths can be replaced according to the requirements of the working environment to achieve different degrees of compaction operations.
