 Said actuator includes a second reciprocating screw mechanism, wherein the sprinkler 19 is mounted on the second nut 18, a motor mounted on the second reciprocating screw sprinkler 20, the sliding shaft 2 is moved back and forth to control the rotational speed of the motor 20 and thus the sprinkler controlling the second momentary speed nut 18 moves back and forth.
 In order to achieve the sliding shaft 2 move back and forth to control the sprinkler 20 in turn controls the motor speed of the second nut 18 moves back and forth instantaneous velocity, is fixed within the frame and a second guide bar parallel to the reciprocating screw 21, the guide bar 21 there are slidable along the slider 22, the slider 22 and the second nut 18 secured together, the rack is fixed to the slide rheostat, the slider 2 on the left end of the slide shaft 23 is fixed to the slide rheostat, the slide rheostat to control watering the rotational speed of the motor 20.
 To install the slide rheostat, said rack has a rectangular box 24, the slide rheostat 24 is fixed within a rectangular box, a rectangular box 24 to the frame via a plurality of connecting rods are secured together, the slide rheostat 20 is connected with the motor via wire sprinkler, rectangular box 24 on the near side of the slide shaft 2 defines a sliding groove, the sliding shaft 2 on the left end of sleeve 25 has set, a bearing mounted between the sleeve 25 and the sliding shaft 2, the sliding contact 23 extending away from the coil end of fixing the sleeve 25 is fixed, by moving the slide shaft 2 around the sleeve 25 can drive the slider 23 is moved left and right turn control the rotational speed of the motor 20 of the sprinkler.
 In order to save manpower, the lower side of said first screw mechanism is fixed to the reciprocating power of the motor 26, power of the motor 26 via the rotation shaft 10 coaxially fixed to the wheel, the rotation power of the motor 26 can drive the wheels 10.
 For convenience control the direction of the vertical axis of the left upper end 7 fixed to the flat bar 27 has a horizontal, flat bar 27 is fixed to the left handle 28, the handle 28 is rotated by the flat bar 27 can be driven by a vertical shaft 7 to control the guide wheels 8 .
 For mounting the sliding shaft 2, the fixed housing 3 is fixed to a vertical riser 29, the sliding shaft 2 through the right vertical plate 29, and without departing from the sliding shaft 2 and between the vertical plate 29.
 The frame 1 is placed on the tank, in turn fixed between the communication pipe 19 via the pump 30, water tank, water pump 30, the head frame 1.
 It is noted that, in the present invention, power of the motor 26 may be a DC motor may be an AC motor, the sprinkler 20 can be DC motor; holding engagement length between the gear 17 and the rack 14; a first reciprocating screw, the two reciprocating screw, each end of the shaft is mounted with bearings; self-powered water pump system 30, can uniform flow at a constant voltage supplied to the nozzle 19 pump 30 is operated; two pinion gears 16 on the first reciprocating screw , two pinion gears 16 are between the first one-way clutch and a reciprocating screw, when the present apparatus is in the curve, the outer side of the pinion gear 16 is greater than the rotational speed of the pinion gear 16 of the rotational speed of the inner, outer pinion gear 16 via a single a first lead screw rotated reciprocally driven clutch, one-way clutch 16 on the inner side of the pinion in the unloaded state. In order to make the sliding shaft 2 can be quickly restitution, compression spring 23 is connected between both ends of said slider chute while the curve becomes a straight line.
Prior to use, the sliding contact 23 of the sliding varistor is in the middle of the resistant wire; activates the sprinkler motor 20, the power motor 26, and the water pump 30, when the device is traveling along the linear trajectory, the axis of the two friction wheel 5 is parallel 2 The power motor 26 rolls the wheel 10, and the wheel 10 is rolled, and the ring gear 11 thereon drives the pinion 16 to rotate, the pinion 16 rotates through the single-way clutch to rotate, the first column is the first nut 15 Move the rectangular cylinder 13 to slide along the U-shaped steel 12, the rectangular cylinder 13 is rotated by the long gear 17, since the central axis of the two friction wheel 5 at this time is parallel to the sliding shaft 2, the sliding shaft 2 is not axially Since the force, the sliding shaft 2 is rotated in place, and does not generate axial movement, the sliding contact 23 does not move left and right, so the sprinkler motor 20 drives the second to the screw-up, at which time the water pump 30 is uniform. The spray head 19 is supplied, and the second nut 18 on which the second nut 18 is driven by the second nut 18 moves the slider 22 to move, so that the bottom nozzle 19 is uniformly sprinkled on the ground; the power motor 26 drives the wheel 10 to move forward, sprinkle water The motor 20 drives the second reciprocating screw.
 When the turned section is encountered, the man hand controls the direction of the guide wheel 8 by the vertical shaft 7, and the vertical rod rotates through the active wheel 6 to rotate, the friction wheel 5 on the passive wheel 4 The central axis of the center axis rotates a certain angle. At this time, the rotation of the sliding shaft 2 generates an axial partial force under the action of the two friction wheel 5, and the axial partial force makes the sliding shaft 2 are also rotated. The left and right direction moves, the sliding shaft 2 is moved through the sleeve 25 to reciprocate the slide contact 23, and the sliding contact 23 moves left and right so that the speed of the sprinkler 20 is always changed, when the nozzle 19 is in the inside of the curve, the sprinkler motor 20 speed fast, when the nozzle 19 is outside the corner, the sprinkler motor is slow.
 The prominent advantages and significant progress of the present invention:
 1. The present invention relates to the phenomenon of inside the outer river in the curved water, and proposes a new sprinkler device, and the sprinkler 19 is moving downward from the inside of the corner, so that The outer pavement can obtain sufficient water volume, in turn, when there is an outer side toward the inner side in the corner, the speed gradually changes, and it is possible to effectively prevent the water from appearing in the inside of the curve, so that the inside and outside the inside and outside the outside.
 2. The present invention can adapt to various curved roads, and can also adapt to different curvatures, which can ensure uniform sprinkle in the linear road area, and can guarantee sprinkle water in the corner area, which is conducive to improve engineering quality and adaptability.
 3. The practicability and applicability of the present invention are relatively wide. For example, the sprinkler maintenance after the water seepage brick sidewalks, this device can effectively prevent excessive sand layer loss caused by excessive sprinkle; Rethinking the planting seedlings in urban parks, the park is generally planned in advance, design Specific shape, then spread the flowers in the region or transplanted seedlings, which is generally an irregular curve. After using the unit, it can be drowned with the seedlings in the case of ensuring that all areas can be fully irrigated. It can help save water resources.
 The structure of the present invention is ingenious, and when the water is sprinkled in the curve, the length of the spray head 19 is residence in the inside of the curve, which is long, so that the inner ring is consistent with the sprinkler of the outer ring, which can make the outer side of the road curve to be sufficient Waterstone, and can effectively avoid the inner ring, so that the entire construction area will maintain a balanced water, which can meet the sprinkle of straight roads, and can adapt to the sprinkle of the corner area, which is conducive to improve construction quality.
