| 20100187330 | Sprinkler head washer stack - A rotatable sprinkler head apparatus has a sprinkler body and a sprinkler swivel for attaching the sprinkler head to a source of water. A spindle rotates in the swivel and has a flange at one end thereof. A three washer stack has upper and lower sealing washers with the upper sealing washer isolated from the rotating spindle by the wear washer and mounted in a counterbore area in the swivel to isolate the upper washer from the rotating spindle and reduce wear on the spindle. The washers counteract the force of the water leaving the sprinkler nozzle to reduce radial movement of the flanged end of the spindle and thus prevents grit from entering adjacent the washers. | 07-29-2010 |
| 20110198411 | Low Flow Sprinkler - An impact sprinkler has a nozzle connected to a housing and a discharge deflector member connected to a rotatable shaft assembly. The sprinkler has different replaceable nozzles and discharge deflectors for providing desired discharge characteristics. The shaft assembly and housing have contacting braking surfaces outside of the water flow providing a frictional braking force dependent on both water flow rate and pressure. The sprinkler has a deflection member for rotating an impact assembly relative to the shaft assembly while a pin supports the impact assembly at a position above the deflection member. A lower portion of the shaft assembly may be positioned in a recess in the housing such that a surface on the shaft assembly contacts a surface in the recess, and a highly wear-resistant material may be disposed on a surface of either the shaft assembly or the recess for providing improved wear characteristics. | 08-18-2011 |
| 20120104116 | PERCUSSIVE SPRINKLER WITH ADJUSTABLE DISCHARGE ANGLE - A percussive sprinkler with adjustable discharge angle has a pedestal, adjusting ring, main body, percussion guide frame and sprinkler head driving rod. The percussive sprinkler is characterized by that, the height of the spacing for the driving rod retaining surface of the adjusting ring can be adjusted via an adjustor, such that the second end on the sprinkler head driving rod connected to the sprinkler head is abutted onto the driving rod retaining surface. When the main body of the percussive sprinkler is rotated, the sprinkler head driving rod will shift vertically along the circumferential path on the driving rod retaining surface, so the sprinkler head is driven to swing vertically with change of the discharge angle. In such a case, spray with different sprinkling distance can be generated by the sprinkler head, thus making up the shortcomings for more uniform sprinkling coverage with higher flexibility and applicability. | 05-03-2012 |
| 20120118994 | Jet-breaker device for jet irrigation apparatus and jet irrigation apparatus comprising such device - A jet-breaker device for a jet irrigation apparatus having a supporting frame with a portion for anchoring it to the launch pipe of an irrigation apparatus, jet-breaker means connected to the frame and designed to at least partially project out of the nozzle of the apparatus for interfering with the outlet jet. The jet-breaker means include at least one jet-breaking element which is designed to oscillate with a predetermined frequency in a plane between a position substantially aligned with the nozzle for interfering with the jet and causing partial breaking thereof, and a position misaligned with the nozzle in which it does not interfere with the jet. The jet-breaker means are motorized for controllably adjusting the oscillation of the jet-breaking element and changing the oscillation frequency thereof. A jet irrigation apparatus incorporating the jet-breaker device. | 05-17-2012 |
| 20120241538 | PERCUSSIVE SPRINKLER WITH ADJUSTABLE BALANCING WEIGHTS - A percussive sprinkler having adjustable balancing weights. The percussive sprinkler has a main body and a diversion member. The percussive sprinkler is mainly characterized in that a guiding section is formed onto the swinging portion of the diversion member, and also sleeved with an adjustable balancing weight. The balancing weight includes a weight stack and an adjuster. Moreover, the adjustable balancing weight can slide axially along the guiding section via the help of the adjuster, so the swinging portion is available with different swinging angles. With this innovative construction, the percussive sprinkler of the present invention has improved operational convenience and adaptability with better applicability and industrial benefits. | 09-27-2012 |
| 20130270363 | IMPINGEMENT SPRINKLER WITH ADJUSTABLE OUTFLOW ANGLE - An impingement sprinkler with adjustable outflow angle has a sprinkler main body, an impingement rotation guiding frame, a water source connecting portion and an adjustment rotating member, so that the main body can be rotated through the adjustment rotating member to adjust the water outflow angle. The adjustment rotating member has a vertical water flow guiding portion provided on top of the water source connecting portion. A rotating pivot joint portion is provided on one side of the vertical water flow guiding portion. A water outlet is opened on the outside of the rotating pivot joint portion. A rotation sleeving portion is provided on the coupling portion of the main body and can sleeve the rotating pivot joint portion. Inside the rotation sleeving portion, a water outflow pass is configured and is connected with the sprinkler main body head on one side of the main body. | 10-17-2013 |
| 20140014739 | IMPINGEMENT SPRINKLER - An impingement sprinkler has a main body, guiding member, tilting regulator, steering control member and steering limiter. The tilting regulator is arranged between the support of main body and the tubing portion on the lower end of the main body, so that the main body can be tilted to change the outflow angle of sprinkler head. The guiding member is located on the support of main body, driving the steering of the main body. The steering control member is installed on one side of the support of the main body to change the rotational direction of the main body. When the main body is tilted, the poke rod of steering control member could be maintained into the limiting ring frame, so that the first or the second limiting member could intervene the poke rod to make the main body retain the steering action. | 01-16-2014 |
| 20140021271 | IMPACT SPRINKLER WITH ADJUSTABLE COUNTERWEIGHT MEMBER - An impact sprinkler with an adjustable counterweight member has a main body, a rotation guiding member, a driving section, and an adjustable counterweight member. The counterweight member is provided on the driving section in a state for segmentation positioning, including a counterweight component and an adjusting structure. The counterweight component can be assembled with or disassembled from the adjusting structure, and the adjusting structure is made up of multiple spaced positioning edges configured on the corresponding positions of the driving section and counterweight component and at least one elastic clamping fringe, and the elastic clamping fringe can be clasped on any positioning edge to fix the counterweight component. This enables flexible adjustment and segmentation positioning of the counterweight component, so as to accurately control the swing angle of the swinging part, and avoid displacement of the counterweight component caused by vibration or collision. | 01-23-2014 |
| 20140042244 | IMPINGEMENT SPRINKLER - An impingement sprinkler is provided wherein the first and second limiting pieces of the rotation limiting mechanism are configured with first and second stopping portions extending along the swinging path. As such, when the main body slants upward or downward, the poking rod portion can always contact the first and second stopping portions. Therefore, the first or second limiting pieces can interfere with the poking rod portion and maintain the function of the main body to shift turning directions. In this way, no matter whether the main body slants upward or downward, it can substantially execute the turning action to sprinkle the surroundings. Hence, the practical utility and usage convenience of the product is greatly enhanced. | 02-13-2014 |
| 20160067725 | IMPINGEMENT SPRINKLER - An impingement sprinkler includes a main frame, a sprinkling device laterally pivotally mounted onto the main frame, an impinging device rotatably mounted on the sprinkling device, a reversing device disposed on the sprinkling device and a limit device is mounted to a lower portion of the main frame, wherein the limit device is operated with reversing device to limit the horizontally rotary angle and accurately control the irrigating area of the impingement sprinkler | 03-10-2016 |
