Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a conveniently adjust elevating gear of troweling machine blade, includes protection casing 1, floating subassembly 2, drive arrangement 3 and action bars 4, floating subassembly 2 includes output rod 21 that floating subassembly 2 links together, and the bottom fixed mounting of output rod 21 has connecting seat 22, installs troweling body 23 with adjustable a plurality of angles on connecting seat 22, and the below of action bars 4 is equipped with adjusts a plurality of connecting seats 22 and carries out wobbling adjusting part 5, wherein:

adjusting part 5, adjusting part 5 include that the cover is established lower pressure disk 56 on output lever 21 and fix the electric jar 51 on action bars 4, and the below of drive device 3 is rotated and is installed shift fork 54, is connected with same cable 55 between shift fork 54 and the electric jar 51.

The driving device 3 comprises a gearbox 31, a motor 32 and a battery 33 which are connected together, an output shaft of the gearbox 31 is fixedly connected with the gearbox 31, and the operating rod 4 is fixedly connected with the gearbox 31.

The adjustment assembly 5 further includes a guide wheel 52 rotatably mounted below the operating lever 4, and a cable 55 is wound around above the guide wheel 52.

Further, install the operating panel of control electric cylinder 51 on operating rod 4 for the in-process that the operator just leveled ground alright with control electric cylinder 51 and drive a plurality of trowel bodies 23 swings, and guide pulley 52 can produce a fulcrum of removal to cable 55, makes the pulling force that cable 55 produced can the vertical action on shift fork 54.
