Description
Technical field
The present invention relates to a kind of surge flow irrigation discharging device, belong to billow irrigating equipment technical field.
Background technology
Surge flow irrigation is a kind of new water-saving irrigation technique that be developed on the basis of surface irrigation, is using water supply
With cut off the water replace occur interval irrigation method, reach the purpose of water-saving and yield-increasing.More traditional surface irrigation mode is compared, billow
Water-efficient irrigation effect is significant, surge flow irrigation using supply water with cut off the water replace generation write a Chinese character in simplified form irrigation method, most outstanding feature just
It is water saving.Furrow are long at 100~300 meters, and intermittent irrigation is more continuously irrigated compared to can economize on water 10%~30%, and intermittent irrigation
Water-saving rate and furrow are long is directly proportional, furrow are long, and water-saving rate is higher, and water-saving result is more obvious.Research shows, intermittent irrigation
Compared with continuous irrigation, identical discharge per unit width, the water delivery speed of intermittent irrigation is continuous 1.2~1.6 times for irrigating.Surge flow irrigation
Irrigate so that irrigation quality raising, soon, speed of pouring water is high for surge flow irrigation current fltting speed, and it is left that efficiency of averagely pouring water can improve 20%
It is right；Reduce the first infiltration capacity of furrow and increased the infiltration capacity of furrow tail, it is to avoid substantial amounts of deep percolation, uniformity of irrigation water appilcation is improved
10%~20%；Can prevent fertilizer from outflowing with water, keep fertilizer efficiency；It is time saving and energy saving, rotation irrigation cycle can be shortened, further expand and irrigate
Area.However, surge flow irrigation is a kind of intermittent water application irrigating, artificial operation usually has many inconveniences, time-consuming, unfavorable
In popularization and application.

One end of 3rd drawstring 24 is fixedly connected through the fixed plate 18 of side plate 16 and the 4th and with one end of latch 21, and the 3rd drawstring 24
Positioned at the inside of second spring 20, water level decreasing to water tank 1/2nd after, the second floater shot 15 declines, due to the second floating
Ball 15 has certain gravity, and the second floater shot 15 moves downward the 3rd drawstring 24 of pulling and compresses second spring 20 so that the
Two portable plates 26 decline, and the first portable plate 5 is closed in the presence of hydraulic pressure, and the upper surface of the 3rd fixed plate 17 is fixedly connected with leads
To bar 25, guide post 25 is movably connected in the inside of the blind hole 27 that the bottom of the second portable plate 26 opens up, by setting guide post 25
So that the second portable plate 26 can only move up and down along guide post 25, and the second portable plate 26 is located at the one of the second fixed block 19
Side, the top of the second portable plate 26 is fixedly connected with half nahlock 28, and the one side of half nahlock 28 is fixedly connected with the second round bar 29,
The quantity of half nahlock 28 is two, and two and half nahlocks 28 and the second round bar 29 form a hinged seat, due to the first portable plate 5
During either on or off, axle moves in a circle centered on the first round bar, and the second portable plate 26 can only be along vertical direction
Motion, so the first portable plate 5 and the second portable plate 26 are necessary for being hinged, the second round bar 29 is movably connected in the surface of connecting rod 30
In the circular hole for opening up, the top of connecting rod 30 is fixedly connected with the lower surface of the first portable plate 5, after the first portable plate 5 is opened, the
Two springs 20 open the bottom that latch 21 is pushed the second portable plate 26, the first portable plate 5 is unlikely in the presence of current
Close, water level decreasing to water tank 1/2nd after, the second floater shot 15 declines, because the second floater shot 15 is with certain weight
Power, the second floater shot 15 moves downward the 3rd drawstring 24 of pulling and compresses second spring 20 so that the second portable plate 26 declines, the
One portable plate 5 is closed in the presence of hydraulic pressure.
When using, the water tank of the present apparatus is connected with irrigation water delivery channel, the delivery port connection farmland water-supply-pipe on base plate
Road；When the water level in water tank rises, the first floater shot 7 is subject to buoyancy, but because first portable plate of effect 5 of pin 12 does not have
It is lifted up, the second floater shot 15 continues to rise, and the first spring is pulled when the second floater shot 15 rises to height higher
11, the first spring 11 draws in the perforation that the one side of the first fixed block 10 is opened up pin 12, and now the first portable plate 5 is first
Opened in the presence of the buoyancy of floater shot 7, after the first portable plate 5 is opened, second spring 20 is opened and for latch 21 to push the second activity
The bottom of plate 26, make the first portable plate 5 be unlikely in the presence of current close, water level decreasing to water tank 1/2nd after,
Second floater shot 15 declines, and because the second floater shot 15 has certain gravity, the second floater shot 15 moves downward pulling the 3rd
Drawstring 24 simultaneously compresses second spring 20 so that the second portable plate 26 declines, and the first portable plate 5 is closed in the presence of hydraulic pressure, and one
The individual cycle completion that discharges water, whole process is convenient and simple without manually operating.
Can to sum up obtain, the present invention passes through the first portable plate 5, pin 12, the first floater shot 7, the second floater shot 15 and first
The setting of spring 11, solves that the artificial operation being related in surge flow irrigation is inconvenient, time-consuming, be unfavorable for asking for popularization and application
