[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.
[0021] like Figure 1-5 As shown, the utility model concrete trowel for construction comprises a connection seat 1 and a trowel device 2 arranged below the connection rod 1, a bubble removal device 4 is also arranged below the connection seat 1, and the bubble removal device 4 comprises a base 43 fixedly connected to the connection seat 1, a vibration cavity 44 is provided inside the base 43, a vibration bottom plate 41 is arranged at the center of the vibration cavity 44, a corrugated elastic plate 42 connected to the base 43 is arranged outside the vibration bottom plate 41, a vibration motor 45 is arranged on the top of the vibration bottom plate 41, a vibration mechanism 46 is arranged on the inner top wall of the base 43, and the lower end of the vibration mechanism 46 is fixedly connected to the vibration bottom plate 41. The trowel device 2 comprises a motor 5, a rotating shaft 6 and a trowel sheet 7.
[0022] The vibration mechanism 46 includes a vibration spring 460 and a vibration sleeve 461. The vibration spring 460 is fixedly installed inside the vibration sleeve 461. The other end of the vibration spring 460 is fixedly connected to the vibration base plate 41. A shock absorbing mechanism 3 is arranged above the connection seat 1. A support column 31 is fixedly connected to one end of the top of the connection seat 1. A spring 32 is sleeved on the outside of the support column 31. A fixed block 33 is fixedly connected to one end of the support column 31. Several buffer springs 34 are fixedly connected to one side of the fixed block 33. One end of the buffer spring 34 is fixedly connected to a connection block 35. A handrail 36 is arranged outside the connection block 35. A buffer block 37 is also arranged between the fixed block 33 and the connection block 35. A motor 5 is also arranged above the connection seat 1. The output end of the motor 5 is connected to a rotating shaft 6. Several trowels 7 are fixedly connected to the circumferential direction of the rotating shaft 6.
[0023] Preferably, by setting up a bubble removal device 4, since the vibration base plate 41 is movably connected to the base 43 through the corrugated elastic plate 42 on the side, during the vibration of the vibration motor 45, it can drive the vibration base plate 41 to move up and down to act on the concrete surface, so as to discharge the bubbles inside the concrete, and the vibration of the vibration base plate 41 and the traction of the device driven manually can drive the leveling device to pass through the surface of the concrete, thereby achieving a leveling effect.

[0025] The working principle of the utility model is as follows:
[0026] When in use, hold the handle 36 and start the motor 5. The motor 5 drives the rotating shaft 6 to rotate, thereby driving the leveling piece 7 to rotate. When the motor 5 is working, part of the vibration generated is decomposed by the support column 31 and the spring 32, and the other part is decomposed by the buffer block 37 and the buffer spring 34, and then passes through the connecting block 35 to the handle 36. At this time, the vibration gradually decreases. The shock absorbing mechanism 3 is used to decompose the vibration generated when the device is working, which avoids the user's hand fatigue caused by huge vibration, thereby improving work efficiency; by arranging a vibration motor 45 inside the base 43, when the vibration motor 45 is running, since the vibration base plate 41 is movably connected to the base 43 through the corrugated elastic plate 42 on the side, the vibration motor 45 can drive the vibration base plate 41 to move up and down to act on the concrete surface during vibration, so as to discharge the bubbles inside the concrete, thereby achieving the leveling effect.
