The utility model aims to solve the technical problem that, overcome prior art's weak point, provide accuracy nature and the stability that can improve rotation mechanism work to improve spray arm job stabilization nature, improve and spray a stop device that presses down dirt sprinkler rotation mechanism of quality and efficiency.

The utility model discloses a technical scheme include the bottom plate, have 2 backup pads around the last skin weld of bottom plate, the backup pad is the L type, is connected with the apron on the top of the riser of 2 backup pads in the front and back, has 2 otic placodes about the lower skin weld of apron, installs electric putter between 2 otic placodes about, articulates with the round pin axle in the diaphragm of 2 backup pads in the front and back has the stopper to it is fixed with the split pin locking at the end of round pin axle.

An inverted U-shaped plate used for limiting the electric push rod is connected between the front supporting plate and the rear supporting plate.

The lower end of the push rod of the electric push rod is connected with a top column.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the utility model discloses install both sides around rotation mechanism base horizontal center line through the mounting hole symmetry on the base when using, with the locating piece cooperation on the rotation mechanism carousel to play the limiting displacement to rotation mechanism, improved the accuracy nature and the stability of rotation mechanism work, thereby improved the stability of spray arm work.

(2) The utility model discloses be connected with the U template of handstand between 2 backup pads in the front and back, this U template and electric putter upper end fixed knot construct the cooperation, have further played and have prevented electric putter wobbling effect, also can play the effect of supporting the enhancement to two backup pads around simultaneously, have further improved the accuracy nature and the stability of rotation mechanism work.

(3) The utility model discloses be connected with the fore-set at electric putter's push rod lower extreme, can play the guard action to electric putter, prevent electric putter's wearing and tearing, after the fore-set wearing and tearing, can change at any time to electric putter's life has been improved.
