It includes water tank, irrigation trunk pipe, irrigation branch pipe and drip irrigation pipe or drip irrigation belt. The water tank comprises tank and floating ball valve, is set on some support high than ground and has inlet connected with a filter and outlet connected with the irrigation trunk pipe. The present invention has integrated irrigation, filtering and fertilizer applying functions.
Description
Technical field
The present invention relates to a kind of system that utilizes gravity to carry out drip irrigation, be particularly useful for the irrigation of greenhouse crops, belong to the agricultural water-saving irrigation technical field.
Technical background
The drip irrigation pattern of applying at present, adopt the field irrigation pipe network to connect the drip irrigation facility, because the pressure of supply water of irrigation pipe network is big, unbalanced, need on drip irrigation equipment, increase pressure compensator, the pressure balance fertilizer apparatus, filters etc. have so often improved the cost of drip irrigation pipe or corollary equipment; At the problems referred to above, the someone has proposed the technical scheme of gravity slight irrigation, and conventional gravity drip-irrigation system improves water level, utilizes the gravity of water to carry out drip irrigation, external valve of water container and filter, Artificial Control.
Summary of the invention
The object of the present invention is to provide a kind of controlled gravity drip-irrigation system, irrigate pipeline and the supporting application of reservoir, the gravity water storage tank is designed to quantitatively controlled, and cooperates dismountable built-in filter, fertilizer applicator, when carrying out drip irrigation, realize the filtration of irrigation water and realize quantitative fertilization.
Technical scheme of the present invention is achieved in that this controlled gravity drip-irrigation system, comprise water storage tank, irrigate main, irrigating arm and drip irrigation pipe or irrigate band constitutes, water storage tank places on the support that is above the ground level, the casing delivery port is communicated with the irrigation main, and the gravity drip-irrigation water storage tank is made of the ball-cock assembly of casing and control water inlet, and inlet pipeline is provided with filter in the casing.
The water storage tank filter of described controlled gravity drip-irrigation system comprises screen pack and the shell that is movably set on the water tank, and the delivery port that is provided with between screen pack and the shell is communicated with water inlet pipe.
The ball float of the ball-cock assembly of described controlled gravity drip-irrigation system water storage tank is provided with through hole, the ball float moving leader therefrom passes, guide rod is provided with overhead gage and lower baffle plate, guide rod and lever hinge joint, and the other end of lever is provided with the spring pressure head and is pressed on the pressing plate that links with the water tank inlet valve body.
Also fertilizer applicator can be set in the casing of described controlled gravity drip-irrigation system water storage tank.
Technical scheme provided by the present invention, can realize quantitative Timing water supply control by water storage tank, realize quantitative fertilization and adjust fertilizer solution concentration that filter and water storage tank are movable to be installed, and can take off at any time and clean, simple and convenient, drip irrigation system collection of the present invention supplies water, filters, topdresses one, reduces the requirement to drip irrigation pipe pressure compensation ability greatly, uses the lower irrigate band of relative cost to get final product, can be developed into and be the auxiliary products supply the market, the whole cost that reduces the drip-irrigation system.

Embodiment
The set-up mode of gravity drip-irrigation of the present invention shown in Figure 1 system, among the figure, water storage casing 16 is arranged at the bracket base 14 that is above the ground level, water outlet of water tank 13 is communicated with the irrigation main, divides into and irrigates arm and irrigate band (pipe), and this drip irrigation system is highly suitable for the control of plastic greenhouse small size drip irrigation, unit of the present invention irrigation quantity is to control by the ball-cock assembly of water storage tank, irrigation water shown in Figure 2 is entered by water storage tank water inlet 1, by filter screen 17 impurity is filtered, and flows into water inlet pipe 3 again; Ball float 7 is provided with through hole, and ball float moving leader 11 therefrom passes, and is provided with overhead gage 6 and lower baffle plate 12 on ball float moving leader 11, and pressing plate 20 shown in Figure 3 is hinged on the support 19, and valve body 23 is hinged on the pressing plate 20.Its course of work is: when water level rose to liquid level 8, ball float 7 promoted overhead gage 6 and drives lever 24 upwards to lift under the buoyancy of water effect, and lever 24 promotes pressure head 22 clamping platens 20 and valve body 23 by spring 21, and outlet pipe is closed.Drip irrigation begins the back water level and descends gradually, ball float 7 along ball float guide rod 11 to lower slider, this moment is under the effect of spring 21, pressure head 22 can not slide to the other end of pressing plate 20, when ball float 7 slides into down liquid level 15, under the effect of gravity, promote lower baffle plate 12 and move downward and affect lever 24 that delivery port is opened, be i.e. dotted line position among Fig. 2 and Fig. 3.
Form the self-locking relation between water storage tank inner spring 21 of the present invention, pressure head 22 and pressing plate 20 threes, in that not have external force to make its state of time spent constant, can be as needs by regulating the lower baffle plate 12 of ball float guide rod 11, the control water tank level keeps constant relatively, thereby has guaranteed stable water pressure water supply.
When needing fertilising, after one embodiment of the present of invention were the water tank filling up water, filter double as fertilizer applicator used, and this mode is suitable for adding liquid fertilizer; Another kind of embodiment is that fertilizer applicator 9 is set in water tank as shown in Figure 2 in addition, fertilizer applicator is identical with the combination and the filter of water tank, the sidewall of fertilizer applicator is porose, inwall also is provided with screen pack, the technical scheme that this ball float 7 slides up and down effectively guarantees timing, quantitative water supply and the fertilising of system, the impurity in the system has been removed in the utilization of sliding screen on the one hand, and it is also very convenient to clean and change filter screen on the other hand.
