Abstract
With the new model of agricultural production and new technology development and application of agricultural machinery will become a major force in agricultural production. In this paper, the analysis of the characteristics of celery harvesting machine work on the basis of the picking from the celery, transit, packaging, etc. for analysis. The main body of the cutting knife and transporting mechanism part of a detailed description. The celery harvesting machine for celery harvest home, simple structure, low manufacturing costs.
The celery harvesting machine parts Bellbottom type structure, the use of fixed cutting knife cutting knife, the paper introduces the body Wedge Lock design process, it may be loosened so the corresponding relaxation. Tool for cutting the course of the situation that may arise to do the corresponding analysis. Also parts of its structure and material to do a detailed analysis. The entire structure is simple, feasible, safe and reliable.
