Embodiment 1

[0028] Embodiment 1 Water-powered strip sprinkler sprinkler combined sprinkler irrigation index field measurement test conditions: sprinkler irrigation time 10min, average wind speed 1.5-2.0m / s, nozzle pressure 0.25MPa, spray elevation angle 21°, blade inclination angle 43°, sprinkler installation height 0.4m, the spraying direction of the nozzle is parallel to the main wind direction, and the rotation of the impeller is consistent, so as to ensure that the spraying direction of the main branch flow remains unchanged during the test.

[0029] The field measurement test results of the sprinkler irrigation index of the hydraulic drive strip sprinkler show that the effective range of the Φ2.5mm single nozzle downwind side is 8m, the maximum range is 9.5m, the effective range of the upwind side is 6m, the maximum range is 7.5m, and the average sprinkler intensity of the downwind side of the single nozzle is 24.36mm / h, the average sprinkler irrigation intensity on the upwind side i...

Embodiment 2

[0031] Example 2 Spray irrigation time is 10 minutes, average wind speed is 1.5-2.0m / s, nozzle water pressure is 0.5MPa, spray elevation angle is 18°, blade inclination angle is 43°, nozzle installation height is 0.5m, nozzle spraying direction is parallel to main wind direction, and impeller turns in the same direction , to ensure that the injection direction of the main branch flow remains unchanged during the test. The diameter of the spray hole is 3.0mm, and the number of blades is 8. Test the irrigation indicators meet the standards.

Embodiment 3

[0032] Example 3 Spray irrigation time is 10 minutes, average wind speed is 1.5-2.0m / s, nozzle water pressure is 0.2MPa, spray elevation angle is 22°, blade inclination angle is 43°, nozzle installation height is 0.4m, nozzle spraying direction is parallel to main wind direction, and impeller rotation is consistent , to ensure that the injection direction of the main branch flow remains unchanged during the test. The diameter of the spray hole is 2.5mm, and the number of blades is 6. Test the irrigation indicators meet the standards.

Abstract

An irrigation device used for row crop comprises a water injection device and a water conveying device which is connected with the water injection device through water pipe. The water injection device comprises a spray pipe and a nozzle fixed at the end of spray pipe. The spray pipe is fixed on a bracket and is installed in parallel with the ground. The nozzle which is fixed at the end of spray pipe is installed with a radial closed impeller. The irrigation device which is used for row crop according to the invention installs the spray pipe in parallel with the ground. Furthermore the nozzle is installed with the radial closed impeller. The water injected from the nozzle is sprayed between the crop rows with a strip shape after scattered by the impeller for directly moisturizing the crop root. The arrangement mode of device in the field adopts a mode of interlaying collocation of spraying units for realizing non-equal irrigation. The water is sprayed on half land under the precondition that all crops are irrigated. The irrigation water is greatly saved and the production cost of foodstuff is reduced.

Description

technical field [0001] The invention relates to a sprinkling irrigation system, in particular to a sprinkling irrigation equipment with a strip-shaped water outlet. Especially suitable for sprinkler irrigation of row crops. Background technique [0002] Sprinkler irrigation is a mechanized irrigation method, and it is also an efficient irrigation technology widely used in the world. According to the practice of our country, compared with traditional ground irrigation technology, sprinkler irrigation can generally reduce irrigation water consumption by 30-50% and increase production by 20-30%. Practice has proved that sprinkler irrigation is of great significance to promote intensive agricultural management and moderate-scale operation, and improve labor productivity and land output rate. More importantly, due to the current shortage of water resources in northern my country, realizing water-saving irrigation is the goal that the government and farmers have been pursuing. H...
