Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0031] like figure 1 As shown, the worm gear transmission system includes a gearbox body 3, a first-stage worm gear train, a second-stage fixed-axis gear train, a third-stage fixed-axis gear train, a manual recovery gear train and a shifting device.

[0032] The first-stage worm gear train includes a first-stage worm gear 24 , a first-stage worm 25 , a first-stage cylindrical bull gear 19 , a first-stage cylindrical pinion 22 and a first-stage rotating shaft 21 .

[0033] The first-stage worm gear 24 meshes with the first-stage worm 25, and the first-stage worm 25 is connected to the motor shaft of the brushless motor through a coupling. The hub of the first-stage cylindrical bull gear 19 is connected with the first-stage rotating shaft 21 through a flat key, the hub of ...

Abstract

The invention provides a worm-gear transmission system of a reel irrigator, and belongs to the field of agricultural water-saving irrigation. The worm-gear transmission system comprises a transmission body, a first-grade worm-gear power train, a second-grade fixed axis gear train, a third-grade fixed axis gear train, a manual recycling gear train and a gear shifting device. According to the worm-gear transmission system, through control of the position of a shifting fork in the gear shifting device, the worm-gear transmission system achieves gear 1, gear 2, neutral gear and manual recycling speed regulation modes; a brushless direct current motor replaces a water turbine to output power, so that the power performance of a prime mover is improved; and worm-gear transmission replaces parts of straight toothed spur gear transmission, so that the transmission ratio of the reel irrigator is increased, the transmission efficiency of the reel irrigator is improved, the size of a transmission is decreased, and the technical problems that under the low-speed operation condition of a traditional reel irrigator, the water turbine is insufficient in power performance and low in efficiency, a traditional transmission has multiple grades and is low in transmission ratio, large in size and low in efficiency, and the like are solved.

Description

technical field [0001] The invention relates to the field of agricultural water-saving irrigation, in particular to a worm gear transmission system for a reel sprinkler irrigation machine. Background technique [0002] The reel sprinkler is a self-propelled irrigation machine mainly driven by a water turbine. Most of the existing reel sprinklers are provided with high-pressure water by a supporting water supply pump. The transmission device drives the reel to realize the recovery of the PE pipe; another part of the high-pressure water enters the PE pipe and is sprayed out from the nozzle on the spraying trolley to realize the spraying operation. [0003] The water turbine of the driving device of the existing reel sprinkler irrigation machine has the disadvantages of insufficient power at low speed, high machine pressure (0.6-1.0Mpa), transmission efficiency lower than 20%, and the like. Using a DC motor instead of a water turbine as a driving device will increase the trans...
