MACHINE AND METHOD OF USING THEREOF
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a clutch, and in particular, to a mechanical clutch of a hose reel sprinkler irrigation machine and method of using thereof.
Description of Related Art
A hose reel sprinkler irrigation machine is irrigation equipment in which a PE hose is wound around a hose reel, power is supplied by a water turbine, motor, or another power source, the hose reel is driven to rotate by a speed variator such that the PE hose is wound back onto the reel, and a sprinkler is drawn to automatically move and spray water. Before sprinkling and irrigation, the hose reel sprinkler irrigation machine needs to use a tractor to draw the sprinkler, to completely pull out the PE hose wound around the hose reel, which is called a hose rewinding process. Before hose rewinding, a clutch needs to disengage to separate a high-speed stage from a low-speed stage of a transmission system. In this way, the whole transmission system is avoided from reverse transmission in the hose rewinding process, and thus is avoided from unnecessary loss caused by an extra load in the hose rewinding process. Moreover, hose rewinding failure caused by the use of a member with a reverse self-locking function such as a worm gear reducer in the transmission system is further avoided. A transmission system of a conventional hose reel sprinkler irrigation machine driven by a water turbine mainly includes a belt drive, a gearbox, and a chain drive from the high-speed stage to the low-speed stage, and a clutch thereof is arranged on the high-speed stage in the gearbox. However, such a gearbox needs to be customized, has a complicated structure and high transmission ratio, and is inapplicable to a novel electrically-driven hose reel sprinkler irrigation machine. In addition, in consideration of actual needs and the use of the worm gear reducer, the clutch is suitably arranged on the low-speed stage, namely, between the chain drive i
and an output end of the reducer.
