Description

Irrigation equipment for water conservancy farmland

Technical Field

The utility model relates to an irrigation equipment especially relates to a water conservancy farmland irrigation equipment.

Background

Drip irrigation is the local irrigation of crops by delivering water through plastic pipes to the roots of crops through orifices or drippers on capillaries with the diameter of about 10 mm. It is the most effective water-saving irrigation mode in arid water-deficient areas at present, and the water utilization rate can reach 95%. Compared with spray irrigation, the drip irrigation has higher water-saving and yield-increasing effects, and can be combined with fertilization to improve the fertilizer efficiency by more than one time. The irrigation system is suitable for irrigation of fruit trees, vegetables, economic crops and greenhouses, and can also be used for irrigation of field crops in arid places with water shortage.

However, the drip irrigation has the disadvantages that the drippers are easy to scale and block, and are commonly blocked by physical blockage, biological blockage and sediment. The physical blockage is the blockage caused by incomplete filtration of silt in water. The sediment blockage is chemical sediment blockage caused by drip irrigation of chemical fertilizers or pesticides. Biological plugging is plugging caused by algae or plant roots. At present, physical blockage and sediment blockage are researched in the market, and biological blockage is responded.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1, 2 show a irrigation equipment of water conservancy farmland, including drinking-water pipe, filter and irrigation house steward, the one end and the cistern of drinking-water pipe are linked together for take out the water in the cistern, during the cooperation water pump use, the other end is fixed on the water inlet of filter, makes the water in the cistern obtain filtering, the filter is the same with the filter commonly used among the prior art, and the primary function is the silt of filtering aquatic, prevents that silt from clogging up the water pipe. The water outlet of the filter is communicated with an irrigation main pipe, and the filtered water can be conveyed to the field for irrigation through the irrigation main pipe.

According to the area in irrigation field, the intercommunication has a plurality of irrigation branch pipes on the irrigation house steward, all is provided with a plurality of heads of driping irrigation on every irrigation branch pipe, and a plurality of heads of driping irrigation are evenly installed on irrigation branch pipe. Drip irrigation and compare other irrigation methods such as spray irrigation and have with strong points, the characteristics of more water-conservation, because the irrigation characteristics of driping irrigation, evenly set up and drip irrigation the head in order to guarantee that all places in the field can obtain the irrigation.

The drip irrigation head comprises a water feeding pipe 1, a water outlet device 2 and a light shield 3. The lower end of the upper water pipe 1 is communicated with the irrigation branch pipe, and the upper end is communicated with the water outlet device. The water supply pipe is used for conveying water in the irrigation branch pipe to the water outlet device.

The water outlet device is spherical or cylindrical, and the water outlet device 2 is arranged on the upper water pipe through the fixed base 4; the water outlet device is provided with a plurality of water outlets 5, and the plurality of water outlets can solve the problem that the water outlet device cannot be normally used after a single water outlet is blocked. The water outlets are uniformly distributed on the side wall of the water outlet device, so that water can be discharged from the water outlet device in all directions.

The water outlet is a rectangle extending downwards, and a gauze is fixed at the water outlet. The gauze of delivery port department can protect in the plant root system can not stretching the delivery port, has solved the problem that the plant root system blockked up the delivery port.

The fixed base is provided with a light shield 3 concentric with the water outlet device, and the light shield is used for shielding the water outlet device and preventing sunlight from irradiating the water outlet device. The outside of water outlet device is arranged in to the lens hood cover, and has seted up on the lateral wall of lens hood and drip irrigation mouth 6, makes the water in the water outlet device only can flow through driping irrigation the mouth, and the purpose is when guaranteeing to drip irrigation the effect, still guarantees that the lens hood can shelter from the water outlet device comprehensively.

The lens hood can rotate for water outlet device, because the position of every drip irrigation head all sets up according to actual conditions, is difficult to guarantee that every water outlet device can both be protected by the lens hood, consequently sets up rotatable lens hood, no matter where the direction orientation of this water outlet device, all can rotate the lens hood, makes the mouth of driping irrigation down, guarantees that water outlet device can not receive sunshine and shines.

The mode that the lens hood was installed on unable adjustment base has the multiple, wherein, on the one hand can be through setting up the track, make clearance fit between lens hood and the unable adjustment base, make the lens hood can rotate, during the use, will drip irrigation the mouth rotation downwards can.

Specifically, a circle of groove tracks are formed on the fixed base around the water outlet device, the bottom end of the light shield is matched with the groove tracks, and the bottom end of the light shield is clamped in the groove tracks, so that the light shield cannot fall off. Meanwhile, a balancing weight 7 is fixed on the light shield, the balancing weight and the drip irrigation opening are on the same side, so that the light shield has a weight difference on one side of the drip irrigation opening, and the balancing weight rotates downwards under the action of gravity, so that the drip irrigation opening faces downwards all the time, and the automatic adjustment function of the light shield is realized.

On the other hand, the fixed base and the light shield can be matched through threads, and the drip irrigation opening faces downwards through manual rotation.

Because the algae grows by the light, the algae is easy to attach to the light shield or the drip irrigation port, and the algae is easy to block the water outlet device when the smaller drip irrigation port or the drip irrigation port is close to the water outlet device, so that the light shield and the water outlet device are spaced, and the area of the drip irrigation port is 1/4 of the area of the side surface of the light shield, thereby ensuring that the use of the drip irrigation head cannot be influenced even if the algae is attached to the drip irrigation port.

The principle of the utility model is as follows:

1. a filter is arranged to filter silt in water, so that the irrigation pipe is prevented from being blocked by the silt;

2. the light shield is arranged to shield sunlight to irradiate the water outlet device, so that growth factors necessary for algae growth in water are blocked, and algae breeding is avoided, and therefore, the water outlet is prevented from being blocked by algae;

3. the large-area light shield protects the water outlet on the water outlet device, and can initially prevent the plant root system from spreading to the water outlet and blocking the water outlet; secondly, a plurality of water outlets are arranged, so that even if one part of the water outlets is blocked by plant roots, the normal work of other water outlets cannot be influenced; and thirdly, the gauze is arranged at the water outlet, so that the plant root system can be prevented from extending into the water outlet device through the water outlet, and the water outlet device can not be blocked by the plant root system.

The above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples, and the technical personnel in the technical field are in the present invention, which can also belong to the protection scope of the present invention.
