Drought resisting fertilizing gun

Abstract

The present invention belongs to the field of the agriculture drought-resistant fertilizer-application machinery, in particular relates to a drought-resistant fertilizer-application gun, which consists of a water-supply pipeline, a fertilizer dissolve box and a water-conveying gun, wherein, the water-supply pipeline consists of a general conduit pipe that is connected with the water source, a water-distribution pipe, a pipe joint, a directional valve and a water conveying joint, the fertilizer dissolve box consists of a dissolving-material case, a case cover, a water inlet pipe with a backwater-proof resistance adjusting valve, an outlet and a material-distributing umbrella-shaped part that is arranged at the lower part inside the dissolving-material case, the water-conveying gun consistsof a case body, a connector, a water inlet pipe, a gun barrel and a head, and the gun barrel can be provided with a pressurizing device that consists of a regulation resistance that is arranged insidea drill gun, a spring and an water-outlet hole that is arranged at the side of the drill gun. Or the water-conveying case can be provided with a water-jet impeller, a balance-weight accelerator, a bushing and a sealing ring. The present invention provides a drought-resistant fertilizer-application gun that has good drought-resistant effect, saves water and can use a great amount of water-retention agent and fertilizer, thereby satisfying the requirements for using the water retention agent on a large area; moreover, the present invention is convenient to be used is safe and reliable, and is easy to maintain.

Description

technical field [0001] The invention belongs to the field of agricultural drought-resistant fertilizing machinery, in particular to a drought-resistant fertilizing gun. Background technique [0002] With the development of agricultural production, the degree of agricultural mechanization is also increasing accordingly. Agricultural drought-resistant fertilization machinery is an inevitable way out for agricultural drought-resistant fertilization. Drought resistance methods currently applied to fruit trees, gardens, and orchards in protected areas include: flood irrigation, sprinkler irrigation, drip irrigation, seepage irrigation, furrow application of water-retaining agents, and topdressing guns. These drought-resistant methods have different disadvantages: flood irrigation wastes water resources, High water demand, poor effect, heavy labor, soil compaction after irrigation, easy to cause orchard disease and insect pest infection, combined with large water flood irrigation...

Problems solved by technology

Drought resistance methods currently applied to fruit trees, gardens, and orchards in protected areas include: flood irrigation, sprinkler irrigation, drip irrigation, seepage irrigation, furrow application of water-retaining agents, and topdressing guns. These drought-resistant methods have different disadvantages: flood irrigation wastes water resources, High water demand, poor effect, heavy labor, soil compaction after irrigation, easy to cause orchard disease and insect pest infection, combined with large water flood irrigation, chemical fertilizers are likely to cause volatilization and waste of chemical fertilizers; sprinkler irrigation requires supporting facilities, complex construction, large investment, waste of water, and daily maintenance The workload is heavy; drip irrigation and infiltration irrigation require supporting facilities, the use conditions are complex, easy to block, large investment, and difficult to promote; ditch water retention agent: water retention agent is a new chemical product for drought resistance. The characteristics of water expansion can make the soil soft, prevent compaction, promote the growth of capillary roots, increase the absorption of fertilizers and trace elements, and at the same time promote the contact of roots with air, creating a good environment for growth

The conventional fertilization method is furrow fertilization, but it is labor-intensive and uneven. If the furrow is shallow, the effect will be poor, and if the furrow is deep, it will hurt the roots of the trees; the traditional topdressing gun is limited to applying a small amount of liquid fertilizer, the tip of the gun is short, and artificial If used on the back, it can’t do anything to the hard ground, and can’t apply a large amount of water-retaining agent and fertilizer, which can’t meet the requirements of using water-retaining agent on a large area; flood irrigation, sprinkler irrigation, drip irrigation, infiltration irrigation, etc. in protected orchards will easily increase the air humidity, and the bacteria will reproduce quickly , there are many pests and diseases, the air humidity is high, the corresponding film has poor light transmittance, and the product quality is low
