[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 , a concrete vibrator, comprising a bottom plate 1, and a vibrating device 2 is arranged outside the bottom plate 1;

[0022] The vibrating device 2 includes a support rod 201, a threaded rod 202, a support plate 203, a top plate 204, a drive motor 205, a vibration motor 206, a vibration rod 207, an electric heating rod 208, an electric heating wire 209 and a heat conductive block 210. The support rod 201 is fixedly installed on the top of the bottom plate 1, the threaded rod 202 is rotatably connected inside the support rod 201, the support plate 203 is threadedly connected on the outer surface of the threaded rod 202, the top of the support rod 201 is fixedly installed with a top plate 204, the top of the top plate 204 is provided with a drive motor 205, the top of the top plate 204 is fixedly installed with a vibration motor 206, the bottom of the support plate 203 is fixedly installed with a vibration rod 207, the electric heating rod 208 is fixedly installed inside the vibration rod 207, the electric heating wire 209 is fixedly installed on the bottom of the electric heating rod 208, and the heat conductive block 210 is fixedly installed inside the vibration rod 207.

[0023] Specifically, Figure 3 As described above, when the vibrating rod 207 is extended into the concrete, the vibration force transmitted causes the tamping cone to impact the concrete below under the action of the gravity of the vibrating rod 207, so that the concrete avoids the tamping cone, thereby reducing the resistance of the tamping cone to move downward, and thereby increasing the descending speed of the vibrating rod 207.

[0024] Specifically, Figure 3As described above, after the electric heating rod 208 and the electric heating wire 209 are turned on, high temperature will be generated inside the vibrating rod 207, and this high temperature will be transferred to the concrete near the vibrating rod 207 through the heat conductive block 210, thereby making the concrete near the vibrating rod 207 more active and increasing the vibration effect.

[0025] Specifically, Figure 1 As described, curved inclined plates are provided on both sides of the bottom plate 1. When the bottom plate 1 moves on the concrete, the curved inclined plates will avoid the concrete, thereby preventing the bottom plate 1 from moving on the concrete and causing concrete to accumulate at one end, thereby destroying the flatness of the concrete.

[0026] When implementing, follow these steps:

[0027] 1) Turn on the driving motor 205 to drive the two threaded rods 202 to rotate through the first gear and the second gear;

[0028] 2) Then, the support plate 203 is controlled by the rotating threaded rod 202 to drive the vibrating rod 207 to move downward through the through hole of the bottom plate 1 and extend into the concrete;

[0029] 3) Turn on the vibration machine and the vibration motor 206 to transmit the generated vibration to the vibration rod 207 through the vibration transmission tube;

[0030] 4) Finally, the electric heating rod 208 and the electric heating wire 209 are turned on to generate heat inside the vibrating rod 207 , and the heat is transferred to the concrete near the vibrating rod 207 through the heat conducting block 210 .

[0031] To sum up, the concrete vibrator, after placing the device on the concrete that needs to be vibrated, turns on the driving motor 205 to drive the two threaded rods 202 to rotate through the first gear and the second gear, thereby controlling the support plate 203 to move downward along the auxiliary rod, and inserts the vibration rod 207 through the through hole of the bottom plate 1 into the concrete, and then turns on the vibration motor 206, generates vibration through the vibration motor 206 and transmits it to the vibration rod 207 through the vibration conduction tube, and then turns on the two vibrators to assist in generating vibration, initially speeding up the vibration efficiency of the concrete, and then turns on the electric heating rod 208 and the electric heating wire 209 to generate heat inside the vibration rod 207, and then transfers the heat to the concrete through the heat conduction block 210, so as to achieve the purpose of vibrating thick concrete without manual holding and speeding up the vibration efficiency.
