Abstract

The invention relates to agriculture and can be used in cones with rotating barrels. The aim of the invention is the possibility of changing the direction of rotation of the barrel during irrigation in the sector. The sprinkler contains a rotary shaft 1, a rocker 3 with a swing axis 2 and a barrel rotation mechanism. The turning mechanism is provided with a second dog 6, connected by means of the cable 8 with the first dog 7 and the trigger mechanism. The trigger mechanism contains a control lever 13 with a groove fixed on the axis 14 and a rotary sleeve 11 with loops 12. The stationary part of the apparatus is equipped with stops 15 that interact with the control lever 13. Under the action of a water jet, the rocker makes oscillatory movements. This movement is transmitted to the barrel 1 by means of the ratchet wheel 9, which rotates the apparatus. When approaching the stop 15 dog, being in engagement with the ratchet wheel 9, comes out, and the second engages. In this case, the direction of rotation of the barrel is reversed. 2 Il. with (/

The invention relates to agriculture and can be used in the design of rotary sprinklers.

The purpose of the invention is to provide the possibility of changing the direction of rotation of the barrel when irrigating over the sector.

FIG. Figures 1 and 2 show the relative positions of the parts when they are viewed in one and the other direction, respectively.

The apparatus consists of a rotating shaft I, on which with the help of axis 2 a rocker arm 3 swings under the action of a jet is fastened. The yokes with axes 4 and 5 strengthened the dogs 6 and 7, which were paired with each other using the ti 8 (to show the relative positions of the parts, pull out the yokes on the yoke). A ratchet wheel 9 is used to rotate the barrel, transmitting its movement to the barrel with the aid of a screw 10, which runs around a stationary tine. Depending on the position in which the bush I1 is located with the pins 12, either the dog or the other interacts with the ratchet wheel. In their extreme positions, the dogs are held by a special spring device.

The position of the hub with studs is controlled by the lever 13, which rotates on the axis 14 when approaching the adjustable stop 15, fixed on the fixed part of the apparatus connected to the stand. The counterweight 16 serves to return the rocker to the starting position.

The device works as follows.

Claims (1)

Under the action of a jet of water, the rocker c6 is an oscillatory motion. This movement by means of a ratchet wheel is transmitted to the barrel, which, depending on how the dog interacts with the ratchet wheel, rotates in one direction or another. When approaching the adjustable stop, the doggie, being in engagement with the ratchet wheel, comes out and the second is engaged. In this case, the direction of rotation of the barrel is reversed. Invention Formula A sprinkler containing a rotary shaft, a rocker with a swing axis and a barrel rotation mechanism including a ratchet wheel mounted on the trunk, a dog mounted on the rocker arm using an axis, the axis of the ratchet wheel being located between the swing axis of the rocker arm and the axis of the dog, characterized in that , in order to provide the possibility of changing the direction of rotation of the trunk when irrigating over the sector, the mechanism of rotation of the trunk is equipped with a second dog connected to the first dog by pulling and a trigger mechanism containing the equal lever with a groove fixed on the barrel by means of a rotary axis, and a rotary sleeve with tongs, one of which is placed in the slot of the lever, and the other is connected to the second dog, while the studs are interconnected by a spring five 0 wife adjustable stops interacting with the control lever.
