Farmland water, fertilizer and pesticide spraying device

Abstract

The invention discloses a farmland water, fertilizer and pesticide spraying device which comprises three vertical columns which are respectively erected at two ends of a farmland, steel ropes correspondingly erected among the vertical columns at two ends of the farmland, nozzle hanging racks arranged by taking the erected steep ropes as track in the air, a coil fixing rope pole and a driving motor thereof mounted on the vertical column at one end of the farmland, fixed pulleys mounted on the poles at two ends of the farmland, a coiling rope wound among the fixed pulleys and the coil fixing rope pole, a nozzle row suspended by the nozzle hanging racks, a pressure container arranged beside the farmland, and a water conveying hose for connecting the nozzle row and the pressure container. By adopting an overhead track structure, not only is the area of the farmland not occupied and is agriculture machine farming facilitated, but also irrigation, fertilization and pesticide spraying are not limited by the landform of the farmland; the heights of nozzles can be adjusted, thereby being applicable to requirements of crops of different heights when sprinkling irrigation, fertilization spraying and pesticide spraying are performed; the capital construction is generally not affected by the landform of the farmland, and moreover the device is simple to operate, uniform in irrigation, fertilization and pesticide spraying, good in effect and high in efficiency.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a farmland water, fertilizer and pesticide spraying device which is fixedly arranged in the air of the farmland and can be moved to perform irrigation, fertilization and pesticide spraying on the farmland crops. Background technique [0002] With the reform and opening up, my country's agricultural production has also achieved considerable development, but the form of farmland operations in agricultural production is still very rudimentary. For example, there are currently two main ways to irrigate farmland: one is to extract groundwater or use surface water. Water, and then use flood irrigation to irrigate the farmland; the second is to bury water pipelines underground in the farmland, and then install one or several rotating nozzles at a certain height above the ground in the field, and spray water through the nozzles 360°rotating to irrigate the farmland. Although these two methods ca...

Problems solved by technology

Although these two methods can effectively irrigate the farmland, it is labor-intensive and time-consuming to irrigate the farmland with the above two methods, and the above-mentioned two methods of farmland irrigation can only be used to irrigate the farmland and cannot be used to irrigate the farmland. In addition to fertilizing farmland and spraying pesticides on crops in the field, the flood irrigation method is also a waste of water resources.

On July 13, 2011, the Chinese patent document disclosed a kind of agricultural machinery with the patent number 201020559884.1 and the name "multifunctional self-propelled mobile sprinkler irrigation machine". Transfer device, the host rail is connected with the inter-span transfer device, the host frame is installed on the host rail, and the sprinkler irrigation machine host is fixed on the host frame; the sprinkler irrigation machine host is composed of a driving motor, a host automatic control system, and a suspended water supply The hose, the spray boom fixed on the lower end of the main machine frame and the nozzle installed on the spray bar are composed. The main engine automatic control system consists of a system control box installed on the upper end of the main machine frame and a control box connected with the system control box and installed on the spray boom. It consists of a manual control box, and the water outlet of the suspended water supply hose is connected with the water inlet of the spray bar. Although this agricultural machine can flexibly and effectively implement the operations of sprinkling irrigation, fertilization and spraying pesticides on field crops, the The working area of ​​agricultural machinery is narrow, so it is not suitable for spraying irrigation, fertilization and spraying pesticides on large farmland, and there are still problems in the operation of this agricultural machinery. Disadvantages of uneven application of pesticides, poor effect, high operating costs, and time-consuming
