Embodiment Construction

[0006] Embodiments are further described in conjunction with the accompanying drawings. The present invention is an improvement on the basis of the prior art. It includes a wet water supply system connected by a main pipe 5, a branch pipe 8 and a wet water supply pipe 7. The main improvement point is to reserve a working channel between the paddy fields 9. At the same time, a layer of peritoneum that can stretch out rice grains is covered on the ground surface in each furrow, and a buoy type dynamic pressure water supply valve 6 is respectively installed on the branch pipe of each furrow moist water supply pipe near the main pipe. There is a pressure vessel 4 (pressure water tank, water tank all can) being communicated between, and a programmable pressure controller 3-3 is outwardly connected with the pressure sensor 2 with wire 3-5 in the pressure vessel loam cake, and the pressure controller's The output ends are respectively connected with the water pump connection line 3-6...

Abstract

The invention relates to an automatic water feeder for moistening and irrigating rice, which comprises a trunk pipe, branch pipes and a rice moistening water feed system formed by connecting moistening water feed pipes. An operating channel is left between every two rice field furrows; a peritoneum, of which rice seedlings can protrude out, is covered on the ground surface of each furrow; a row of moistening water feed pipes are respectively installed under each peritoneum; the branch pipes of the moistening water feed pipe adjacent to the trunk pipe in each furrow are respectively provided with a row of moistening water feed pipes; the branch pipes on the moistening water feed pipe adjacent to the trunk pipe in each furrow are respectively provided with a pontoon type dynamic pressure water feed valve; a pressure container is arranged between the trunk pipe and a water pump; the inside of the upper cover of the pressure container is outwardly connected with a programmable pressure controller by a wire through a pressure sensor; the output end of the pressure controller is respectively connected with the water pump and lines of a computer; the pressure controller is installed in a cabinet; an air switch connected with power supply wires and the pressure controller is also arranged in the cabinet. The invention has the advantages of water conservation, continuity and precision, and full automation.

Description

Technical field: [0001] The invention relates to the cultivation of rice, in particular to an automatic water supply device suitable for wet irrigation of rice. Background technique: [0002] At present, the main irrigation technology for paddy fields in my country is still submerged irrigation. In recent years, the wet irrigation technology that does not establish a water layer for rice is emerging. There is a complete technical solution. At present, the manual control and intermittent wet irrigation water supply mode are commonly used. The disadvantages are that the labor intensity is high, and it cannot reach the level of continuous and precise automation. Invention content: [0003] The purpose of the present invention is to provide an automatic water supply device for rice wet irrigation that not only saves labor and water, but also is continuous, precise and highly automated. [0004] The technical scheme of the present invention is accomplished in the following mann...
