Abstract
An apparatus for irrigating the earth includes a portable vehicle having a hose reel connected to a supply of water under pressure. An elongated hose is carried by the reel and the end of the hose is connected to a travelling carriage having a water gun and such carriage initially is moved away from the vehicle by an external force after which water passing through the apparatus drives a turbine which rotates the reel and coils the hose thereon while pulling the carriage toward the vehicle at a selected speed so that a large area of the earth is watered automatically.
Claims12
An irrigation apparatus comprising, a vehicle, a reel support frame carried by said vehicle, a reel rotatably mounted on said reel support frame and in spaced relationship to the earth, an elongated flexible hose carried by said reel, means for supplying water under pressure to one end of said hose, the opposite end of said hose being connected to a water gun movably mounted on a travelling carriage, parallelogram means mounting said water gun on said carriage and permitting limited movement of said water gun along a generally vertical plane, means urging said water gun toward an upper position, and means for rotating said reel in one direction to cause said hose to be wound thereon and move said travelling carriage toward said vehicle, whereby the weight of said hose and the water carried thereby normally maintain said water gun in a lowered position until said carriage is located near said vehicle and said reel supports the weight of said hose which permits said urging means to raise said water gun.
In an irrigation apparatus having a hose reel with a hose rotatably mounted on a portable vehicle and having a water gun connected to the hose and mounted on a travelling carriage, in which the vehicle is positioned in a given location and the carriage is pulled away, unwinding the hose as it is pulled, and in which water is supplied to the hose at the reel and passes through the hose to the water gun, and means is provided for using the force of the water before it passes into the hose on the reel to rotate the reel and wind the hose thereon, thereby moving the carriage toward the vehicle, the improvement comprising, said means for rotating the reel comprising a turbine, means to bypass a portion of the water through said turbine before it enters the hose on the reel, valve means for controlling said bypass means, said reel having a ring gear, a spur gear mounted on said vehicle and in engagement with said ring gear, means for driving said ring gear from said turbine, brake means mounted to disengage and engage said spur gear selectively, pawl means selectively engageable with said ring gear for permitting said ring gear to rotate in the direction for winding said hose on said reel but preventing rotation in the opposite direction, whereby said brake means governs the rotation of said reel when the hose is being pulled off of the reel in order to avoid free rotation thereof during the paying out of said hose.
