Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

A simple concrete vibrating device comprises a vibrating motor 1, wherein an output shaft of the vibrating motor 1 is provided with an oval turntable 2 which is vertically arranged; a first platform 3 which is horizontally arranged is arranged below the turntable 2, an arc-shaped groove 31 along the vertical projection direction of the turntable 2 is arranged on the upper surface of the first platform 3, and the lower surface of the first platform 3 is connected with a second platform 4 through a telescopic device 32 and a first return spring 33 which is sleeved outside the telescopic device 32; the telescopic device 32 comprises a cylindrical shaft sleeve 321 with a circular through hole on the upper surface, and further comprises a telescopic shaft 322 vertically arranged and penetrating through the circular through hole, wherein the telescopic shaft 322 is connected with the upper surface of the second platform 4 through a second return spring 34 at the bottom; a plurality of third return springs 5 are uniformly arranged on the lower surface of the second platform 4, and the second platform 4 is connected with a vibrating platform 6 below through the third return springs 5; the vibrating motor further comprises a motor platform 11 arranged at the bottom of the vibrating motor 1 and a shell 12 sleeved outside the vibrating motor, wherein the motor platform 11 is fixed inside the shell 12; the bottom of the shell 12 is provided with a bearing slope 121 which is folded inwards, the bearing slope 121 is uniformly provided with fourth return springs 7, and the tail ends of the fourth return springs 7 are arranged at the bottom of the second platform 4.

The working principle of the utility model is that when the vibrating motor 1 is switched on, the output shaft drives the vertically arranged oval turntable 2 to rotate, and because the oval turntable 2 has a long shaft and a short shaft, the vibrating motor 1 periodically outputs acting force to the first platform 3 with the arc-shaped groove 31 arranged below the turntable 2; when the long axis of the turntable 2 is vertical, the pressure is maximum, and when the short axis is vertical, the pressure is minimum, and the pressure is used as an output power source of the whole vibrator; the action point of the turntable 2 and the first platform 3 is continuously changed in the arc-shaped groove 31 along with the rotation of the turntable 2; the first platform 3 continuously applies a periodically changing pressure to the lower expansion device 32 under the action of the turntable 2, so that the second platform 4 below the expansion device 32 makes a corresponding displacement along with the continuous compression and extension of the first return spring 33 sleeved outside the expansion device 32 and the second return spring 34 arranged inside the expansion device 32. Because a plurality of third return springs 5 are uniformly arranged between the second platform 4 and the vibrating platform 6, the third return springs 5 are correspondingly compressed and extended along with the continuous up-and-down displacement of the second platform 4, so that the vibrating platform 6 is driven to move up and down, and the vibrating effect on the surface of the concrete is achieved; because the vibrating platform 6 has a large area, the concrete to be vibrated can be sufficiently vibrated, so that the concrete is compacted, air bubbles are discharged, and the process purpose is achieved. Because the bottom of the shell 12 is provided with the bearing slope 121, and the bearing slope 121 is connected with the second platform 4 through the fourth inclined return springs 7, the whole body formed by the first platform 3, the second platform 4, the vibrating platform 6 and the return springs among the first platform 3, the second platform 4, the vibrating platform 6 and the second platform is in close contact with the turntable 2, and the idling of the turntable 2 caused by insufficient contact force is prevented.
