Description

Dual-low sprinkling-drip irrigation method

Technical field

The present invention relates to field of agricultural irrigation, is a kind of dual-low sprinkling-drip irrigation method.Particularly be a kind of have low cost, low energy consumption sprinkling-drip irrigation method.

Background technology

At present, water-saving irrigation is paid close attention to by society step by step along with the overall scarcity of China's water resource.Using water wisely, rationally utilize water resource to mention the day thing agenda of functional government departments.Therefore, agricultural irrigation and be that the water yield is The more the better.But select different irrigation methods for use according to different crops, if any crops adapt to dry-land cultivation, just should the ground flood irrigation, and should take to spray or the method for drip irrigation.As CN85108475A, disclose denomination of invention and be " sprinkler line for localized irrigation ", be can disposable after a kind of usefulness that is used for localized irrigation pipeline of sprinkling irrigation, having pipe by one constitutes apart from the flexible pipe in hole, also have the interior flexible membrane that sticks to above-mentioned hose inner wall by means of near solder joint last 3 holes, diaphragm and hose inner wall form the gap having under the situation of current; Otch is arranged on interior diaphragm.These otch are positioned at well-regulated interval equally, with respect to the hole intervening portion of outer flexible tube.Between two adjacent welds, has hole outside at least.Has an interior otch at least corresponding to outer hole.But this part has disclosed the pipeline of sprinkling irrigation of disposable.But do not relate to the spray drip irrigation scheme of system.

Summary of the invention

The present invention will overcome disclosed comparison technology and wait perfect problem, and purpose is to provide a kind of dual-low sprinkling-drip irrigation method to this area, is also referred to as the sprinkling-drip irrigation method of low cost, low energy consumption.Make it solve these type of crops and need spray to irrigate or drip and irrigate, and the too high problem of prior art cost.The objective of the invention is to realize by following technical solution.

A kind of dual-low sprinkling-drip irrigation method is to be the water source with reservoir, river course, irrigation canals and ditches, arranges fixing person in charge or mobile arm, utilizes the potential difference at water source or the method for water pump diversion sprinkling irrigation or drip irrigation, it is characterized in that four kinds of set sprinkling-drip irrigation methods select one and select:

A), fixing be responsible for 2 and connect at least one mobile arm 6, on mobile arm 6, connect a head cartridge 7 at least; Head cartridge is by articulation 7.1, vertical tube 7.2, and three-legged support 7.3, snap joint 7.5 constitutes; The fixing person in charge's 2 a end and the water of reservoir 1 are logical, and the end is provided with filters net cage 4, and the other end connects safety valve 3 or drain valve.

B), fixing be responsible for 2 and connect at least fixedly arm 8, fixedly connecting a base valve 9 at least on the arm 8, the base valve is by spool 9.0, valve seat 9.1, vertical tube 9.6, base 9.7, pin 9.8, valve gap 9.9 formations; The fixing person in charge's 2 a end and the water of reservoir 1 are logical, and the end is provided with filters net cage 4, and the other end connects safety valve 3 or drain valve.

C), mobile water pump assembly 10 is communicated with river courses or irrigation canals and ditches 11, water inlet pipe 12, intake crane 13 and at least one fixedly arm 8, fixedly at least one base valve 9 of connection on the arm 8.

D), mobile water pump assembly 10 is communicated with river course or irrigation canals and ditches 11, water inlet pipe 12, intake crane 13 and at least one stationary pipes 14, stationary pipes connects at least one ball valve 16, ball valve connects at least one little water spray and is with 15; Ball valve is by shower nozzle 16.1, handle 16.2, and import 16.3, snap ring 16.4, spool 16.5 constitutes.

Above-mentioned described four kinds of sprinkling-drip irrigation methods have the characteristic of low cost, low energy consumption, so be called " two low ".The user according to different geographical position, landform, condition select one to be sprinkling irrigation or drip irrigation, make the required moisture content of crops suitable, realize using water wisely, rationally utilize water resource.

Embodiment

The present invention's first design is that to irritate with the water droplet spray of reservoir 1 be example as shown in Figure 1.Fixing be responsible for 2 and connect water sources, lay at a fixing end of arm 2 and filter net cage 4, filter the impurity in the reservoir, other end connection safety valve 3.The fixing person in charge 2 hydrant and fast interface 5 are set, the mobile arm 6 of configuration is to drip area with spray to establish, just solve the related area of its length by the head cartridge 7 that is disposed on the mobile arm 6 in the use, belong to semi-fixed type or claim portable sprinkling-drip irrigation method, 350 yuan/mu of average costs, suitable hillside fields, mountain area spray drip irrigation.

Second design as shown in Figure 3.With reservoir 1 water, be on the water pipe at least one base valve 9, at least one shower nozzle to be set for the moment equally, promptly in vertical tube 9.6, insert shower nozzle at every.This scheme is fixed entirely, and fixedly arm 8 is not established gate valve, and vertical tube 9.6 belongs to moving members, and vertical tube 9.6 and fixing arm 8 are by 9 fast connections of base valve.Being the pedestal of vertical tube, is again valve, and vertical tube inserts, valve open, on the contrary valve is closed automatically.Become the arm gate valve and be controlled to be vertical tube control, be single shower nozzle control.The every fixing arm shower nozzle of working simultaneously, by many fixedly arm be equipped with corresponding shower nozzle and work simultaneously.Cause fixedly arm is small-bore, reduces cost, 450 yuan/mu of average investments, suitable mountain area spray drip irrigation.

The 3rd design is not established the person in charge, gate as shown in Figure 5, water intaking in river course or irrigation canals and ditches 11.Do not build pumping plant, be fixedly arm 8 water supply in turn by mobile water pump assembly 10.Fixedly arm is embedded in undergroundly, and vertical tube 9.6 (see figure 4)s of base valve 9, shower nozzle move, fixedly arm nearby the water source end be provided with and connect water inlet pipe 12, intake crane 13.Be applicable to the plain river network irrigated area, 400 yuan/mu of average costs.

The 4th design as shown in Figure 6, stationary pipes 14 is embedded in underground, does not establish arm, stationary pipes 14 middle parts are provided with intake crane or fast interface, are supplied water by mobile water pump assembly 10, pick out ground by threeway, connect little water spray by ball valve 16 and are with 15.The little water spray bandwidth of wall scroll 30～70mm has seven kinds of specifications, and little water spray band is provided with aperture, and five kinds of specifications of diplopore～seven apertures in the human head are arranged, four kinds of aperture φ 0.4～1.0mm, and every little water spray strip length is controlled in 70 meters.Or the little water spray band of 30mm, 45mm is distributed in the mulch film, become microspray irrigation under the film.If little water spray band is changed into thin wall irrigation belt, just become portable drip irrigation.250 yuan/mu of average costs, suitable flat area.

The above-mentioned described fixedly person in charge, mobile arm, stationary pipes, little water spray band are all selected polymer (PE) material for use, have the corrosion-resistant performance, are easy to install and move.
