Proportional layering fertilizer applying device

Abstract

The invention discloses a proportional layering fertilizer applying device, belonging to agricultural machinery. The proportional layering fertilizer applying device is formed by connecting an outer channel wheel type fertilizer feeder, a fertilizer amount regulating, controlling and distributing assembly and a layering fertilizer applying device, wherein the outer channel wheel type fertilizer feeder comprises a shell, a spiral linear outer channel wheel and a fertilizer amount regulating and controlling sleeve; the spiral linear outer channel wheel is installed in the shell; through the connection and fit of an internal screw thread on the fertilizer amount regulating and controlling sleeve and an external screw thread on the spiral linear outer channel wheel, the fertilizer amount regulating and controlling sleeve is axially and movably arranged on a side part of the spiral linear outer channel wheel, and a cylindrical barrel-shaped outer wall of the fertilizer amount regulating and controlling sleeve entirely covers the spiral linear outer channel wheel; and the layering fertilizer applying device is formed by assembling a fertilizer delivering pipe, a separating plate, a pipe base, an elastic fastener assembly, a rear fertilizer applying tail pipe, a front fertilizer applying pipe and a furrow opener. The proportional layering fertilizer applying device disclosed by the invention achieves the purpose of proportionally applying seed fertilizer and additional fertilizer at one time in a layering way, and has the characteristics of simple and reasonable structure, good working quality, high efficiency, low cost, convenience in regulation and control, high utilization efficiency of fertilizer, and the like.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a fertilization device. Background technique [0002] At present, field crop seeders such as corn and wheat also apply chemical fertilizers while performing sowing operations, commonly known as base fertilizer or seed fertilizer application, which can ensure the nutrients required for crop seed germination and seedling growth. The increase of nutrients requires additional fertilization, commonly known as topdressing. At this time, most areas in my country still adopt the fertilization method of throwing chemical fertilizers on the surface, resulting in the volatilization and loss of chemical fertilizers, and the crop roots cannot fully absorb nutrients, resulting in the loss and waste of a large amount of chemical fertilizers; at the same time , Putting manpower and material resources into topdressing has increased the production cost of grain. The latest experiments show that deep f...
