Mobile fertilizing and chemical spraying integrated device

Abstract

The present invention relates to a movable single unit system of fertilizer injection and pesticide spraying; the present invention comprises a machine frame; land wheels equipped at the bottom of the machine frame; a fertilizer / pesticide bucket for containing fertilizer or pesticide; a pressure pump which is connected with the fertilizer / pesticide bucket by a first controllable valve; to pressurize the injected pesticide and is connected with a water inlet joint by a fourth controllable valve to pressurize the injected water and is connected with a nozzle to spray the pressurized pesticide; a fertilizer injection pump which is connected with the fertilizer / pesticide bucket by the first controllable valve and connected with a flow sensor and the pressure pump by a third controllable valve and also connected with a water outlet joint to mix the water injected from the pressure pump and fertilize injected from the fertilizer / pesticide bucket and to spray the mixture from the water outlet joint; a controller used for controlling the opening and closing of the controllable valves and the stop of the pressure pump. The device can be moved conveniently which solves the problem that the water pressure of drip irrigation is low; the efficiency is low and additional fertilizer can not be applied on the seedling stage; at the same time the device is characterized by the functions of fertilizer injection and pesticide spraying.

Description

technical field [0001] The invention relates to an agricultural machine used for fertilizer injection and pesticide spraying, in particular to a mobile integrated device for fertilizer injection and pesticide spraying. Background technique [0002] Facility agricultural production has changed the traditional development and operation mode of vegetable production. At present, in order to reduce the humidity in the facility, most facility agriculture production areas have converted traditional flood irrigation into drip irrigation in production. Drip irrigation technology uses drippers on dry pipes, branch pipes and capillary pipes to drip water slowly to the soil under low pressure; it is an irrigation system that directly supplies filtered water, fertilizers or other chemicals to the soil. It doesn't spray or ditch water, it just lets the water trickle out slowly and into the soil by gravity and capillary action. It is an advanced irrigation method to drip water near the ro...
