Hand-held point irrigation water injector

Abstract

The invention discloses a hand-held point irrigation water injector, which belongs to an agricultural machine. A quantitative water injection pipe is sealed and arranged in a hole on the lower end of a water storage pipe; a water stopping valve plate is arranged in the water storage pipe in a way of being capable of moving up and down; an annular gap is reserved between the water stopping valve plate and the water storage pipe; the water stopping valve plate is contacted, sealed and matched with the quantitative water injection pipe; a connecting rod is arranged in the cavity of the quantitative water injection pipe; the upper end part of the connecting rod is fixedly connected with the water stopping valve plate and the lower end part of the connecting rod is provided with a boring cone body; the upper cone body part of the boring cone body is contacted, sealed and matched with the wall face of an inner orifice on the lower end of the quantitative water injection pipe; and the handleis arranged on the outer part of the upper side of the water storage pipe. The injector has the advantages of simple structure, low manufacturing cost, simple and convenient use and operation, uniform and consistent water injection amount, good point irrigation water injection effect and high water source utilization rate and is particularly suitable to be used for fighting against drought, protecting seedlings and promoting crops to grow after sowing operation in small and medium dry land.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a water injection semi-mechanized tool used for drought-resistant operation of upland crops. Background technique [0002] Due to the vast northern regions of my country, especially Heilongjiang, Jilin and other provinces, the soil moisture is poor and the water content is low during the spring dry field crop planting season, commonly known as "nine spring droughts in ten years". In order to ensure the germination rate of seeds after sowing as much as possible, the traditional method is to use bowls, ladles and other utensils to hold water and irrigate the soil surface near the seeds. Reduced, water loss and evaporation loss increase, resulting in waste of water resources. In addition, for small plots of rural land, modern large-scale sprinkler irrigation, drip irrigation equipment and supporting water conservancy facilities are not only not suitable for small plots of farmers, but...

Problems solved by technology

In order to ensure the germination rate of seeds after sowing as much as possible, the traditional method is to use bowls, ladles and other utensils to hold water and irrigate the soil surface near the seeds. Reduced, water loss and evaporation loss increase, resulting in waste of water resources

In addition, for small plots of rural land, modern large-scale sprinkler irrigation, drip irrigation equipment and supporting water conservancy facilities are not only not suitable for small plots of farmers, but also require huge investment, which is difficult for rural farmers in our country to bear. No prospects for promotion and application
