Abstract
The invention relates to an application of the water jet technology in cleaning, spraying and excavation of roots and stalks of aquatic plants, in particular to a water gun for aerated pulse water jet, which can eject water jet with better erosion performance under lower water pressure. After entering the water gun, a water flow is prepared into the aerated water jet first and then oscillated to the aerated pulse water jet to be sprayed out of the water gun. The aerated pulse water jet can lead to the cavitation, so that the erosion performance of the water jet is improved. The erosion effect of the water jet can reach the publicly-known erosion effect of the water gun under higher water pressure. When the roots and stalks of the aquatic plants are excavated, the water gun has a better erosion effect under the submerged condition, the aerated pulse water jet is sprayed in the soil at the water bed, rising air is also involved in the tilling of the soil at the water bed, the excavated roots and stalks are pushed to float upward, and the excavation efficiency is obviously improved. The recoil of the water gun is small after use, and the labor intensity of an operator is obviously reduced.
Description
Technical field
The present invention relates to the water-jet technology field, is a kind of hydraulic giant of using under the low-pressure low flow condition of being applicable to.This hydraulic giant can spray preferably water jet of erosion property in the lower situation of hydraulic pressure, and jet length is distant.The erosion effect of this hydraulic giant institute water-jet can reach the known hydraulic giant erosion effect that institute's water-jet produces when hydraulic pressure is higher.When reaching identical erosion effect or jet length, this hydraulic giant water consumption, less energy intensive.This hydraulic giant can be applicable to cleaning, sprinkling and water plant rhizome and the purposes such as excavates.
