Description
Technical field
The utility model relates to a kind of water-saving irrigation device, relates in particular to major-minor runner mini sprinkler rotary body.
Background technology
Agricultural is the water rich and influential family, and irrigation water accounts for more than 90% in agricultural water; China's agricultural water efficient is low, and the average water efficiency of irrigation in the whole nation is far below developed country, so enforcement high-efficiency agriculture water conservation strategies improves modern agriculture irrigation technique level and is very important; Along with the adjustment of China's agricultural planting industry structure and the raising of peasant economy condition; Industrial crops and warmhouse booth cultivated area increase fast; Requirement to irrigation conditions improves; City-building is to the attention of environmental greening and the swift and violent increase of urban greening area in addition, and is increasing to the microspray irrigation technology requirement; The microspray irrigation technology is a kind of advanced irrigation technique of effective adjusting crop water, and microspray irrigation adopts pipeline water delivery, sprays near ground; Significantly reduced the loss in evaporation loss and the water delivery process, microspray irrigation is a localized irrigation in addition, has reduced the invalid water consumption of part soil; Thereby water saving, having energy-conservation, the high characteristics of all even quality of pouring water of pouring water simultaneously, microspray irrigation can also combine uses such as crop foliage dressing, spray medicine; Fogging degree is higher during water spray, can increase crop humidity, regulates the soil moisture; Can control the humidity and the temperature on the face of land preferably, reduce the generation of disease and pest, improve quality and the output of crop; Therefore, in industrialized agriculture and featured agriculture plantation, obtained using widely.Microspray irrigation is mainly used in surface irrigation, like greenhouse vegetable, grow seedlings, flower culture etc. has higher requirements to humidity, can realize to crop irrigation with regulate protection ground ambient humidity or temperature, help plant growth, and can realize cleaning the effect on crop blade face.
Microspray irrigation employing mini sprinkler is irrigated near current are sprayed at crop with tiny water droplet; The similar drizzle of microspray irrigation can not damage crop during irrigation, can regulate field microclimate, and stronger, lower to the requirement of water treatment than the anti-blockage capability of drip irrigation; Microspray irrigation is adaptable across multiple occasions such as fruit tree, flowers, vegetables, nursery, lawn, warm canopies; Mini sprinkler is the key equipment of microspray irrigation, and the effect of mini sprinkler is through aqueduct pressure water stream to be sprayed equably, satisfies the demand of crop normal growth to moisture; The performance of douche directly has influence on the height of the quality of pouring water, the reliability and stability of irrigation system; Therefore, attach great importance to development and exploitation both at home and abroad to douche; The total development trend of douche is that the direction towards low-pressure energy-saving develops, and can not only reduce energy resource consumption like this, and can use the low pressure plastic tube, has reduced the tubing cost.
Chinese patent Granted publication number: CN2571495Y; Granted publication day: on September 10th, 2003, disclose " a kind of rotating micro-sprinkler, it includes water spout and rotary body; it is characterized in that: on the framework that the upper end of damper housing is fixed on water spout is connected; be evenly equipped with damping fin on the damper shaft, and its two ends rotational support is in the hole of damper housing top and bottom, and the upper end of rotary body is connected with the lower end of damper shaft; Through damper the rotating speed of rotary body is reduced, thereby compare advantage with water spray far firing range with existing mini sprinkler." this rotating micro-sprinkler exists and spray inhomogeneously, has the water yield many nearly few drawbacks far away, and because deviation of gravity center, shake is big in the rotation process.
Summary of the invention
The utility model technical problem to be solved provides major-minor runner mini sprinkler rotary body; It has the sprue control water yield at a distance; The characteristics of the secondary channels control water yield nearby; Improve the uniformity of spraying greatly, guaranteed that simultaneously the center of gravity of rotary body is on the center line of rotary body rotation, overcome the big phenomenon of shake in the rotation process.
For solving the problems of the technologies described above; The utility model adopts following technical proposals: major-minor runner mini sprinkler rotary body, and it comprises water inlet, the sprue that is opened in the rotary body sidewall, the secondary channels that is opened in the rotary body sidewall that can be connected with the water spout rotation socket joint of mini sprinkler, can insert the support turning cylinder in the locating hole on the mini sprinkler framework; Said sprue and secondary channels are provided with the arc guiding gutter; The junction, lower end of said sprue and secondary channels arc guiding gutter overhangs the unsettled top that is arranged at water inlet of end; So that the separating liquid that is flowed into by water inlet gets into sprue and secondary channels; The vertical height h that said secondary channels roof distance overhangs end is the half the of the sprue roof distance vertical height H that overhangs end; So design can make in the current spraying range far, closely the water yield is consistent, guarantees that the water distribution of spraying range is even.
Said sprue arc guiding gutter top and secondary channels arc guiding gutter top all are structure in a zigzag; The zigzag structure of said sprue and the zigzag structure of secondary channels edge are around the equidirectional bending of central shaft; So that current are during through sprue and secondary channels; Apply lateral thrust to same the turning to of rotary body, make the rotary body rotation.
The outer camber line parameter of the arc guiding gutter of said sprue and secondary channels is identical, and arc angle is 45 °～49 ° of angles, and arc radius is 115mm～125mm.
The arc angle of camber line is 40 °～44 ° in the said sprue guiding gutter, and the arc radius of camber line is 103 mm～107 mm in the sprue guiding gutter, and the arc angle of camber line is 33 °～37 ° in the said secondary channels guiding gutter, arc radius 50 mm～54 mm.
The junction, lower end of said sprue and secondary channels arc guiding gutter overhangs end distance, and the vertical line distance is 1mm～3mm from the water inlet upper surface.
The vertical line that the junction, lower end of said sprue and secondary channels arc guiding gutter overhangs end is positioned at the position of the diameter line 7:3 of water inlet; The course of work is that the water yield 70% through the water spout water inlet enters into sprue; The water yield that sprue sprays mainly is distributed in medium and long distance; The water yield 30% through the water spout water inlet enters into secondary channels, and the water yield that secondary channels is sprayed mainly is distributed in closely, and this mode through the major-minor runner can make current leave spray body from different endpoint curves; Shed different positions; Make the watering amount be evenly distributed on far, in, on the near soil, guaranteed to spray more even, compare advantages such as having the water spray range is big, all even rotation stability of rotation of water distribution with existing mini sprinkler.
The utlity model has the sprue control water yield at a distance; The characteristics of the secondary channels control water yield nearby; Improved the uniformity of spraying greatly; The center of gravity that has guaranteed rotary body simultaneously is on the center line of rotary body rotation, and mini sprinkler rotation stability of rotation has overcome the big phenomenon of shake in the rotation process.
