Because the automatic reversing water sprayer 31 is further included, the automatic reversing water sprayer 31 includes a first bevel gear 311, a second bearing seat 312, a second rotating rod 313, a second bevel gear 314, a third bearing seat 315, a third rotating rod 316, a first belt pulley 317, a first transmission strip 318, a second belt pulley 319 and a second transmission strip 3110, the automatic reversing water sprayer 31 is arranged above the support plate 3, the first bevel gear 311 is connected to the front side of the second rotating shaft 305, the second bearing seat 312 is installed in the middle of the front side of the connecting plate 17 in a bolt connection manner, the second rotating rod 313 is connected to the second bearing seat 312, the second bevel gear 314 is connected to the left end of the second rotating rod 313, the second bevel gear 314 is meshed with the first bevel gear 311, the third bearing seat 315 is installed at the upper end of the support plate 3 in a bolt connection manner, the third rotating rod 316 is connected to the third bearing seat 315, the first belt pulley 317 is connected to the left end of the third rotating rod 316 and the right end of the second rotating rod 313, a first transmission bar 318 is connected between the first belt pulleys 317, a second belt pulley 319 is connected between the right side of the first rotating bar 5 and the right end of the third rotating bar 316, a second transmission bar 3110 is connected between the second belt pulleys 319, when a user needs to use hydraulic power to enable the spray head 18 to automatically rotate to spray water, when the first rotating bar 5 rotates, the first rotating bar 5 drives the lower side second belt pulley 319 to rotate, the lower side second belt pulley 319 drives the upper side second belt pulley 319 to rotate through the second transmission bar 3110, the upper side second belt pulley 319 rotates to drive the third rotating bar 316 to rotate in the third bearing seat 315, the third rotating bar 316 rotates to drive the upper side first belt pulley 317 to rotate, the upper side first belt pulley 317 rotates to drive the lower side first belt pulley 317 through the first transmission bar 318, the lower side first belt pulley 317 rotates to drive the second rotating bar 313 to rotate, the second rotating bar 313 drives the second bevel gear 314 to rotate, the second bevel gear 314 rotates to drive the first bevel gear 311 to rotate, the first bevel gear 311 drives the second rotating shaft 305 to rotate, so as to drive the sector gear 306 to rotate, thereby driving the nozzle 18 to rotate, and thus, the force for rotating the nozzle 18 by manual operation can be saved.
Because still including placing cover 3121, the bottom plate 1 right side is connected with places cover 3121, places the suction pipe 12 in placing cover 3121, the user can place suction pipe 12 in placing cover 3121, can avoid like this that rivers impact to suction pipe 12 makes it stir into by carousel 6.
