Description

Major-minor runner mini sprinkler rotary body
Technical field
The present invention relates to a kind of water-saving irrigation device, particularly relate to major-minor runner mini sprinkler rotary body.
Background technology
Agricultural uses water rich and influential family, and irrigation water accounts for more than 90% in agricultural water, China's agricultural water efficiency is low, the average water efficiency of irrigation in the whole nation far below developed country, so, implement high-efficiency agriculture water conservation strategies, improve modern agriculture irrigation technique level and be 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, the requirement of irrigation conditions is improved, in addition city-building is to the swift and violent increase of the attention of environmental greening and urban greening area, increasing to the demand of microspray irrigation technology, microspray irrigation technology is a kind of advanced irrigation technique of effective adjustment crop water, microspray irrigation adopts pipeline water delivery, near ground spray, greatly reduce the loss in evaporation loss and water delivery process, in addition microspray irrigation is localized irrigation, decrease part soil inavailable water consumption, thus economize on water, have energy-conservation simultaneously, the feature that all even quality of pouring water of pouring water is high, microspray irrigation can also in conjunction with crop foliage dressing, the uses such as spray medicine, during water spray, fogging degree is higher, crop humidity can be increased, regulate the soil moisture, the humidity and temperature on earth's surface can be controlled preferably, reduce the generation of disease and pest, improve the quality and yield of crop, therefore, obtain in industrialized agriculture and featured agriculture plantation and apply widely.Microspray irrigation is mainly used in surface irrigation, as greenhouse vegetable, nursery, flower culture etc. have higher requirements to humidity, can realize crop irrigation and regulate protecting field ambient humidity or temperature, being conducive to plant growth, and can realize the effect of cleaning crop blade face.
Microspray irrigation adopts mini sprinkler to be sprayed near crop with tiny water droplet by current and irrigates; The similar drizzle of microspray irrigation, can not damage crops 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 widely used in the multiple occasions such as fruit tree, flowers, vegetables, nursery, lawn, warm canopy; Mini sprinkler is the key equipment of microspray irrigation, and the effect of mini sprinkler is sprayed equably by pressure water stream by aqueduct, meets the demand of crop normal growth to moisture; The performance of douche directly has influence on the height of quality of pouring water, the reliability and stability of irrigation system; Therefore, the Study and Development to douche is attached great importance to both at home and abroad; The total development trend of douche is the future development towards low-pressure energy-saving, can not only reduce energy resource consumption like this, and can use low pressure plastic pipe, reduce tubing cost.
Chinese patent Authorization Notice No.: CN2571495Y, authorized announcement date: on September 10th, 2003, disclose " a kind of rotating micro-sprinkler; it includes water spout and rotary body; it is characterized in that: the upper end of damper housing is fixed on the framework that is connected with water spout; damper shaft is evenly equipped with damping fin, and its two ends are rotatably supported 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; By damper, the rotating speed of rotary body is reduced, thus there is the advantage of far firing range of spraying water compared with existing mini sprinkler." this rotating micro-sprinkler exists and spray uneven, there is the water yield how close few drawback far away, and due to deviation of gravity center, in rotation process, shake is large.
Summary of the invention
Technical problem to be solved by this invention is to provide major-minor runner mini sprinkler rotary body, it has sprue and controls the water yield at a distance, secondary channels controls the feature of the water yield nearby, substantially increase the uniformity of sprinkling, ensure that the center of gravity of rotary body is on the center line of rotary body rotation simultaneously, overcome in rotation process and shake large phenomenon.
For solving the problems of the technologies described above, the present invention adopts following technical proposals: major-minor runner mini sprinkler rotary body, and it comprises and can rotate with the water spout of mini sprinkler water inlet, the sprue being opened in rotary body sidewall, the secondary channels being opened in rotary body sidewall, the support rotating axle that can insert in the locating hole of mini sprinkler framework upper end that socket joint is connected; Described sprue and secondary channels are provided with arc guiding gutter, the junction, lower end of described sprue and secondary channels arc guiding gutter overhangs the unsettled top being arranged at water inlet of end, so that the separating liquid flowed into by water inlet enters sprue and secondary channels, the vertical height h that described secondary channels roof distance overhangs end is the half that sprue roof distance overhangs the vertical height H of end, design like this can make in current spraying range far away, closely the water yield is consistent, ensures that the water distribution of spraying range is even.
Described sprue arc guiding gutter top and secondary channels arc guiding gutter top are all in zigzag structure, the zigzag structure of described sprue and the zigzag structure edge of secondary channels are around the equidirectional bending of central shaft, so that when current are by sprue and secondary channels, turn to applying lateral thrust to rotary body is same, rotary body is rotated.
Described sprue is identical with the outer camber line parameter of the arc guiding gutter of secondary channels, and arc angle is angle 45 ° ~ 49 °, and arc radius is 115mm ~ 125mm.
In described sprue guiding gutter, the arc angle of camber line is 40 ° ~ 44 °, and in sprue guiding gutter, the arc radius of camber line is 103 mm ~ 107 mm, and in described secondary channels guiding gutter, the arc angle of camber line is 33 ° ~ 37 °, arc radius 50 mm ~ 54 mm.
It is 1mm ~ 3mm that the junction, lower end of described sprue and secondary channels arc guiding gutter overhangs end distance water inlet upper surface vertical line distance.
The vertical line that the junction, lower end of described 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 enters into sprue by the water yield 70% of water spout water inlet, the water yield that sprue sprays mainly is distributed in medium and long distance, secondary channels is entered into by the water yield 30% of water spout water inlet, the water yield that secondary channels is sprayed mainly is distributed in closely, this mode by major-minor runner can make water flow energy leave spray body from different endpoint curves, shed different positions, watering amount is made to be evenly distributed on far, in, on near soil, ensure that sprinkling is more even, there is range of spraying water compared with existing mini sprinkler large, the advantages such as all even rotary motion of water distribution is steady.
The present invention has sprue and controls the water yield at a distance, secondary channels controls the feature of the water yield nearby, substantially increases the uniformity of sprinkling, ensure that the center of gravity of rotary body is on the center line of rotary body rotation simultaneously, mini sprinkler rotary motion is steady, overcomes in rotation process and shakes large phenomenon.
