A rotary press fertilization device

Abstract

The invention discloses a rotary downward pressure fertilizing device. The device comprises a hydraulic cylinder, a connecting plate, a flange plate, a hydraulic motor, a fixed base, a telescopic rod,a fertilizing sleeve and a drill bit, wherein the hydraulic cylinder is mounted on the connecting plate and provided with a piston rod, the piston rod is connected with one end of the flange plate, the other end of the flange plate is fixedly connected with the hydraulic motor, and two ends of the telescopic rod are fixed on the connecting plate and the fixed base respectively; telescopic adjustment is performed with lifting of the piston rod of the hydraulic cylinder, an output shaft of the hydraulic motor drives the drill bit to rotate, and the drill bit comprises a drill tip provided witha fertilizer outlet and a hollow drill rod provided with a drainage groove, the maximum distance between a spiral blade arranged at the drill tip and the axis of the drill bit is smaller than the radius of the hollow drill rod; the fertilizing sleeve is provided with a fertilizing inlet, one end of the fertilizing sleeve is connected with the fixed base, and the other end of the fertilizing sleeveis connected with the hollow drill rod. Soil is not discharged out of the ground, the problem of insufficient precision of soil backfilling and fertilization is solved, the device has the characteristics of simple structure and high interchangeability, and efficient hole digging and accurate fertilization are achieved.

Description

technical field [0001] The invention relates to the technical field of orchard fertilization machinery, in particular to a rotating and pressing fertilization device. Background technique [0002] Orchard fertilization is a key link in the entire orchard management operation, and it is an important process. At present, the traditional method of fertilization for fruit trees adopts manual ditching or digging holes for fertilization, which is inefficient and prone to excessive or insufficient fertilization. Material resources are seriously wasted; however, most of the orchard fertilization machines currently appearing use vertical auger bits to dig holes, furrow plows or ditch knives to open furrows, and then fertilize. These two methods will cause soil backfilling problems and insufficient fertilization accuracy. , affecting fertilization efficiency. Contents of the invention [0003] In order to overcome the defects and deficiencies of the prior art, the present invention...
