AI Technical Summary

Technical Problem

Existing trenching and fertilizing machines are not suitable for the low and narrow spaces of hilly orchards, which means that trenching and fertilizing operations in orchards rely on manual labor and cannot meet the mechanization needs of the modern forestry and fruit industry.

Method used

An offset trenching and fertilizing machine was designed, which uses an offset trenching component and scraper component, combined with a transmission system, to realize the integration of trenching, fertilization and soil covering. It reduces the vertical height of the equipment, adapts to operation in low and narrow spaces, and achieves uniform spreading of fertilizer through the vibration and displacement of the scraper component.

Benefits of technology

It enables efficient trenching and fertilization operations in low and confined spaces, improves fertilizer uniformity and soil covering effect, reduces equipment costs, and is suitable for widespread use.

Abstract

This invention discloses an offset trenching and fertilizing machine, including a frame connecting a carrier, a trenching component mounted on the side of the frame, a fertilizing component mounted on the top of the frame, and a scraper component elastically mounted at the rear of the trenching component. After the trenching component digs a trench on the ground, the soil on both sides of the trench is scraped back into the trench by the scraper component, completing the trench covering. The fertilizing component, in conjunction with the scraper component, spreads fertilizer into the trench before the soil is scraped into it. The machine also includes a transmission system that drives the trenching component and the fertilizing component. An adjusting rod is slidably fitted at the bottom corner of the frame, and a limit wheel is rotatably mounted on the outer side of the adjusting rod. A locking screw is fitted between the frame and the adjusting rod. The vertical height of this equipment is reduced, making it suitable for operation in low and confined spaces.
