Description

Dual-purpose hydraulic hook lock device Technical Field The utility model relates to the technical field of mechanical positioning, in particular to a dual-purpose hydraulic hook lock device. Background In farm machinery, the working end of the paddy field flat ground stirrer is longer, and after the paddy field flat ground stirrer is installed on a large-sized folding rotary tillage machine on sale, the paddy field flat ground stirrer is widely applied to farmlands when transported on roads, and the spacing between the surrounding roads and the fields is narrower, so that plants on two sides of the roads can be damaged during transverse transportation, or the working end of the paddy field flat ground stirrer can be bumped by barriers on two sides of the roads. Based on the current situation, technical staff in the prior art develop a paddy field land leveling mixer capable of realizing folding, normally push in the transverse direction during working, and transport longitudinally after folding during running on a field road or road. However, when the folding paddy field land leveling mixer is found during work and transportation, after long-time running, the folding paddy field land leveling mixer is not stable enough after being folded longitudinally or unfolded transversely, and has a certain inclination problem, and a rotating shaft at a folding joint can be damaged after the folding joint is inclined, so that the inclination angle is further deepened, and the using effect of equipment is affected.
