Adopting above -mentioned scheme, having made things convenient for the regulation of driping irrigation the in -process volume of dripping, the regulative mode is convenient simultaneously utilizes the gravity of water self to drip irrigation with the operation, has removed the reliance to running water (pressure water) from, and the environment is suitable for can the reinforce.
Description
Technical field
This utility model relates to agricultural equipment technical field.
Background technology
Drip irrigation (dripirrigation) is to utilize plastic conduit that by diameter, water is about the aperture on 10mm hollow billet or water dropper is delivered to crop root and carried out localized irrigation.It is the maximally effective a kind of Water Saving Irrigation Mode of current drought and water-scarce area, and the utilization rate of water is up to 95%.Drip irrigation is relatively sprayed and is had higher water-saving and yield-increasing effect, in conjunction with fertilising, can improve fertilizer efficiency more than one times simultaneously.It is applicable to fruit tree, vegetable, industrial crops and warmhouse booth to irrigate, can also be used for field crop irrigation in the place of drought and water shortage.Its weak point is the easy fouling of water dropper and blocking, and therefore reply water source carries out strict filtration treatment.For bigger plant, and the position comparatively concentrated carries out the convenient adjustment drip irrigation amount one by one of drip irrigation needs one, and regulate the control device of the amount of dripping whenever and wherever possible；Simultaneously when not having water works, carrying out drip irrigation by the natural water pressures such as bottled water (gravity), owing to pressure is too small, existing equipment cannot normal operation.
Utility model content
This utility model is intended to provide a kind of convenient crops drip irrigation controller regulating the amount of dripping.
Crops drip irrigation controller in this programme, including shell, upper press cover, lower cover from top to bottom it is sequentially provided with in shell, forming infiltration chamber between upper press cover and lower cover, upper press cover has water inlet, the external water inlet pipe of water inlet, lower cover has outlet, outlet picks out water pipe, is connected to elastic component between described upper press cover and outer casing inner wall, is connected to lower elastic component between lower cover and outer casing inner wall；Being provided with air bag between upper press cover and lower cover, the outer surface of this air bag and water inlet, outlet offset, the external aerating device of this air bag.
Beneficial effect: current pass into from water inlet pipe, the water inlet being provided with of upper press cover is arrived by action of gravity, owing to upper press cover and lower cover are pushed against by air bag, even it is closed completely so water inlet and outlet only leave fine gap so that the amount of dripping at least or is zero；By starting aerating device, in air bag, pour air, make airbag inflation, air bag promotes upper press cover and lower cover to move so that elastic component shrinks, and increases the contact area of air bag and water inlet, outlet, reduce the opened gap of water inlet, outlet, reduce the amount of dripping；Otherwise, aerating device pressure release, increase the amount of dripping；Adopting such scheme, facilitate the adjustment carrying out the amount of dripping in drip irrigation process, regulative mode is convenient simultaneously utilizes the gravity of water self to carry out drip irrigation with operation, eliminates the dependence to tap water (press water), and it is strong that environment is suitable for ability.
Further, described aerating device includes elastic gas tank, and elastic gas tank is provided with check valve, pressure-relief valve；Manual squeezing elasticity gas tank, air is undertaken in chamber by check valve, and air flows in air bag, is inflated, and pressure-relief valve term sheds chamber air pressure.
Further, described elastic gas tank is additionally provided with automatic pressure reducing valve, when air pressure reaches the critical threshold values of air relief valve, releasing pressure automatically, it is to avoid burst air bag.
Further, described upper press cover and lower cover are provided with sealant, increase the sealing between upper press cover and outer casing inner wall, lower cover and outer casing inner wall.
Further, described upper elastic component is compression spring, and lower elastic component is lower stage clip, and simple in construction, cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model crops drip irrigation controller embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: shell 1, upper press cover 2, water inlet pipe 21, compression spring 22, lower cover 3, outlet 31, lower stage clip 32, air bag 4, elastic gas tank 5, check valve 51, automatic pressure reducing valve 52.
Embodiment is substantially as shown in Figure 1:
Crops drip irrigation controller in this programme, including shell 1, upper press cover 2 and lower cover 3, described upper press cover 2 and lower cover 3 from top to bottom successively inner sleeve in shell 1, forming infiltration chamber between upper press cover 2 and lower cover 3, upper press cover 2 has water inlet, and water inlet is connected to water inlet pipe 21, lower cover 3 has outlet 31, outlet 31 and outlet pipe connect, and be connected to compression spring 22, be connected to lower stage clip 32 between lower cover 3 and shell 1 inwall between described upper press cover 2 and shell 1 inwall.
Having clamped air bag 4 between upper press cover 2 and lower cover 3, the outer surface of this air bag 4 and water inlet, outlet 31 offset, and air bag 4 is connected to aerating device.Aerating device includes elastic gas tank 5, and elastic gas tank 5 is provided with check valve 51, pressure-relief valve；Manual squeezing elasticity gas tank 5, air is undertaken in chamber by check valve 51, and air flows in air bag 4, is inflated, and pressure-relief valve term sheds chamber air pressure.
Elastic gas tank 5 is also equipped with automatic pressure reducing valve 52, when air pressure reaches the critical threshold values of air relief valve, releasing pressure automatically, it is to avoid burst air bag 4.Upper press cover 2 and lower cover 3 are provided with sealant, increase the sealing between upper press cover 2 and shell 1 inwall, lower cover 3 and shell 1 inwall.
Operation principle: current pass into from water inlet pipe 21, the water inlet being provided with of upper press cover 2 is arrived by action of gravity, owing to upper press cover 2 and lower cover 3 are pushed against by air bag 4, even it is closed completely so water inlet and outlet 31 only leave fine gap so that the amount of dripping at least or is zero；By starting aerating device, manual squeezing elasticity gas tank 5, air is undertaken in chamber by check valve 51, and air flows in air bag 4, is inflated pouring air in air bag 4, air bag 4 is made to expand, air bag 4 promotes upper press cover 2 and lower cover 3 to move so that compression spring 22 and lower stage clip 32 shrink, and increases the contact area of air bag 4 and water inlet, outlet 31, reduce the opened gap of water inlet, outlet 31, reduce the amount of dripping；Otherwise, to open pressure-relief valve and shed chamber air pressure so that compression spring 22 and lower stage clip 32 shrink and open, the contact area of increase and decrease ballonet 4 and water inlet, outlet 31 increases the opened gap of water inlet, outlet 31, increases the amount of dripping.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the premise without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
