Abstract
An automatic plant water arrangement having one water intake and several water outflows which are preceded by valves. The valves are actuated by a time-controlled mechanism, and are individually adjustable for different opening cycles. The time-controlled mechanism has a synchronous motor with a gear reduction unit, a single-tooth wheel and a mating gear with attached valve actuating disk. The valve actuation disk is provided with teeth, part of which are fixed and part of which are movable for opening the valve. A segment-shaped cam disk is located underneath the valve actuating disk, and is controlled by gears so that it pivots one of the movable teeth every sixth day into the valve engagement region. The teeth, after leaving the region are returned by springs to their initial positions.
Claims18
An automatic plant watering arrangement comprising, in combination:
- water intake means;
- a plurality of water outflows;
- valves connected to said water outflows;
- timer means;
- time-controlled means connected to said timer means for actuating said valves, means for adjusting said valves individually for different opening cycles;
- said time-controlled means comprising a synchronous motor with gear reduction means, a single-tooth wheel and mating gear, and valve actuation disk means connected to said gear;
- said valves comprising water hoses and clamping means for closing and opening said hoses;
- said clamping means comprising a clamping lever for opening and closing said valves;
- and pawl means actuated by said clamping lever;
- water pump and motor means;
- switch means for controlling the operation of said pump and motor means, said pawl means actuating said switch means;
- worm-gear spindle means actuated by said pawl means, said pawl means after actuating said worm-gear spindle means tilting said clamping lever for opening all valves.
A plant watering arrangement comprising, in combination:
- water intake means;
- a plurality of outflow watering lines;
- valves connected to said watering lines;
- means for actuating said valves and having a valve actuating disk with a plurality of adjacently located circular tracks with different numbers of valve control cams;
- a synchronous motor and gear reduction drive means;
- a gear connected to said valve actuating disk;
- a one-tooth wheel on said reduction drive means and engaging said gear connected to said disk so that for each revolution said one-tooth wheel rotates said gear by an angle corresponding to one tooth, said valve actuating disk remaining stationary between control motions of said gear, said valves being controlled by said cams, said valves being arranged around said disk, said valves being located on different ones of said circular tracks, different numbers of valve actuating cams being associated with said tracks.
