Description

Technical Field

[0001] This application relates to the field of power trowels, and more specifically, to a shock-absorbing device for power trowels. Background Technology

[0002] There is a protective frame on the outside of the power trowel, and the main body of the power trowel is set inside the protective frame. Generally speaking, the protective frame is directly fixed to the main body of the power trowel, mainly to the motor of the fixed part of the power trowel. When the power trowel is in use, the motor is running, so the motor will generate a lot of vibration. The protective frame connected to the motor will also generate a lot of vibration. If it is in a vibrating environment for a long time, the connection between the two can easily become loose or damaged. Utility Model Content

[0028] A vibration damping device for a power trowel, the power trowel including a motor 12 and a support frame 11, the motor 12 being mounted on the support frame 11, and the vibration damping device disposed between the motor 12 and the support frame 11. The vibration damping device includes: a first connecting member 1, a second connecting member 2, and a buffer pad 3 disposed between the first connecting member 1 and the second connecting member 2. The first connecting member 1 is fixed to the support frame 11, and the second connecting member 2 is fixed to the motor 12. The buffer pad 3 forms a damping layer between the support frame 11 and the motor 12, effectively preventing the vibration of the motor 12 from being transmitted to the support frame 11, thus preventing vibration of the support frame 11 and preventing damage to parts due to mutual vibration. Multiple vibration damping devices are evenly distributed between the support frame 11 and the motor 12, resulting in better vibration damping performance.

[0029] Specifically, the first connector 1 has a first connecting chamber, and a first connecting pipe 4 is provided between multiple first connectors 1; the first connecting pipe 4 is used to connect the multiple first connecting chambers; the second connector 2 has a second connecting chamber, and a second connecting pipe 5 is provided between multiple second connectors 2; the second connecting pipe 5 is used to connect the multiple second connecting chambers; the vibration damping device also includes a water pump 6, which is connected to the first connecting pipe 4 and the second connecting pipe 5, and the water pump 6 is connected to an external water source. By using the water pump 6 to inject water into the first connecting pipe 4 and the second connecting pipe 5, water can fill the multiple first connecting chambers and the second connecting chamber. Since the water fills the first connecting chamber and the second connecting chamber, that is, the middle part of the first connector 1 and the second connecting chamber 2 is filled with water, the water can effectively reduce vibration, thus providing a better vibration damping effect.

[0030] Specifically, the shock absorption device further includes a water injection pipe 7, a drain pipe 8, and a water collection tank 9 connected to the water injection pipe 7 and the drain pipe 8; both the water injection pipe 7 and the drain pipe 8 are connected to the first connecting pipe 4 and the second connecting pipe 5; control valves are installed on both the first connecting pipe 4 and the second connecting pipe 5, with the water injection pipe 7 and the drain pipe 8 located on either side of the control valves. The water pump 6 and the water collection tank 9 are mounted on the support frame 11. The control valves allow water to be injected and completely fill the first and second connecting chambers before draining into the water collection tank 9 via the drain pipe 8. The water pump 6 repeatedly injects and discharges the water, keeping it in a flowing state. Therefore, the flowing water can absorb more vibration, further improving the shock absorption effect. The first connecting pipe 4, the second connecting pipe 5, the water injection pipe 7, and the drain pipe 8 are all made of flexible hoses.

[0031] Specifically, a branch pipe 10 is provided on the water injection pipe 7, with the outlet of the branch pipe 10 facing downwards; a pressure relief valve is provided on the branch pipe 10. The power of the water pump 6 can be increased to significantly increase the pressure in the water injection pipe 7, after which water will overflow from the pressure relief valve on the branch pipe 10. Therefore, in some cases, when the surface being polished by the power trowel is too dry, this method can be used to quickly add water to the surface.

[0032] The elastic pad includes a first pad portion and a second pad portion; the first pad portion has a groove, and the second pad portion has a protrusion, the protrusion being inserted into the groove; the first pad portion is connected to the support frame 11, and the second pad portion is connected to the motor 12. This can effectively increase the shock absorption effect.

[0033] Specifically, both the first connector 1 and the second connector 2 are fixed to the buffer pad 3.

[0034] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
