At present, the irrigation of small size crops such as plastic tunnel, garden crop, urban afforestation lawn, flower bed etc. does not still have irrigation system and the device that effectively utilizes water resource.Generally utilize water pipe directly landing ground to be watered, not only water resource can not effectively be utilized, and causes the phenomenon of wasting water, and irrigation effect is also bad.In order to address this problem, the applicant has applied for that the patent No. is 98211314.5, patent name comes with some shortcomings for " Positioning drip irrigation apparatus " this patented technology empirical tests, as produce the irrigation rig complex procedures, the water yield size is adjusted inaccuracy, it is time-consuming to adjust the location dropper, and the screen pack installation and the replacing program of filter are cumbersome.

The utility model content

The utility model is to the improvement in first to file, the purpose of this novel Positioning drip irrigation apparatus be to provide a kind of easy to operate, water yield adjustment accurately, the drip irrigation appliance of drip irrigation accurate positioning, and using water wisely helps keeping ground temperature again, reduces soil water evaporation, reduces air humidity.

The technical solution of the utility model is: novel Positioning drip irrigation apparatus is connected to form in turn by water tank, filter, water yield distributor, connector and location dropper, scalable filter screen bracket is set in the described filter, in the middle of this support is bracket upright post, fixed disc and movable disc are set on the column, be connected by movable rod between fixed disc and the movable disc, be covered with screen pack on the filter screen bracket; Anti-blocking screw is set on the described connector, and anti-blocking screw is provided with pointed water inlet, and water yield adjustment screw is arranged in the anti-blocking screw and with anti-blocking screw thread and is connected, and it is water channel that the water yield is adjusted the screw inner chamber, and the lower end is provided with is inverted the triangle water inlet; Described location dropper inner chamber is provided with positioning tie bar, and the water inlet of dropper contacts with the positioning tie bar outer wall, and the location dropper is divided into plurality of sections, and every section evenly is provided with four delivery ports.

Can be provided with between water tank and the filter and add fertile case, add fertile case water inlet and be connected with the water tank water-supply-pipe, add fertile case delivery port and be connected with filter, add fertile case top and be provided with charge door, the below has been provided with sewage draining exit and blowoff valve.Make chemical fertilizer or agricultural chemicals can locate deep placement, improve chemical fertilizer utilization ratio.

The utility model can be selected single head formula filter or bull formula filter for use according to irrigated area size and water quality quality, and bull formula filter is that a plurality of screen packs are set in filter; According to the difference of irrigated crop, connector can be selected bullhead or bull formula for use, and bull formula connector is a plurality of anti-blocking screws to be set be connected with the location dropper on connector.

The utility model water tank, filter, water yield distributor, connector, location dropper link to each other in turn, can realize that the water in the water tank enters the soil bottom.The size of water yield can be adjusted screw by the water yield and accurately adjust, and the position of drip irrigation can accurately be adjusted by the pull bar of location dropper in soil.The utility model is because water tank is in a high position, therefore when drip irrigation, need not pressurization for the second time, utilize water-head both can realize drip irrigation, energy savings consumes, and can be embodied in the soil bottom again and irrigates, and table soil is dry and comfortable, avoid the soil moisture evaporation, using water wisely keeps surface temperature, reduces air humidity.This device is accurately convenient to the adjustment of water yield, drip irrigation position, and when irrigating, can also carry out the location deep placement of chemical fertilizer, agricultural chemicals, and control crop root damage by disease and insect improves chemical fertilizer utilization ratio.
