The working principle is as follows:
after the troweling machine is started, the engine 16 rotates to drive the connected power rod 17 to rotate, because the power rod 17 is sleeved with the first transmission ring 18, the first transmission ring 18 is driven to rotate, the second transmission ring 21 is driven to rotate under the action of the transmission belt 19, the handle 8 is pressed at the moment to drive the connected handle 5 and the L-shaped pressing block 25 to press downwards, the pressing column 25 sinks to abut against the pressing plate 32, the pressing plate 32 presses downwards and drives the transmission shaft 14 connected with the pressing plate 32 to sink, and therefore the bevel gear 15 at the upper end of the transmission shaft 14 can be meshed with the bevel gear 33 fixed on the end face, extending into the second box body 30, of the second transmission shaft 20 on one side to form power transmission. Meanwhile, the pressing of the pressing plate 32 presses the first spring 13 at the lower end, and the first spring 13 transmits the pressure to the fixing ring 27 at the lower end, so that the chassis cover 2 sinks to play a role in protection.
At the moment, the movable sleeve 34 sinks due to the downward pressing of the pressing plate 32, the distance between the movable sleeve and the chassis cover 2 is reduced, the movable connecting rods 7 around the movable sleeve are driven to rotate downward, the sliding blocks 42 above the chassis cover 2 are pushed outwards, hydraulic oil in the sliding hydraulic grooves is extruded into one end close to the outer side of the chassis cover 2, the sliding rods 46 in the sliding hydraulic grooves retract, and the protection of the spatula 10 is cancelled.
When the hand is separated from the handle 8 or forgets to turn off the motor 16, which results in the unmanned trowel, due to the lack of downward pressure, the second spring 12 and the first spring 16 bounce, push the pressing plate 32 to rise, and simultaneously lift the transmission shaft 14 to be separated from the meshing state, and the trowel at the bottom does not work any more, thereby improving the safety. Meanwhile, as the pressure plate 32 rises and the distance between the pressure plate and the movable sleeve 34 is increased, the movable rod 7 around the movable sleeve is lifted and rotated to pull back the sliding block 42, and meanwhile, hydraulic oil in the sliding hydraulic groove is pulled back, so that the sliding rod 46 inside the movable sleeve extends out to play a role in protecting the spatula 10.
The key block 9 on the handle is used for temporarily starting the engine 16 when the power is cut off due to no reason during the use of the troweling machine.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
