摘 要

随着新的农业生产模式和新技术的发展与应用，农业机器人将成为农业生产的主力

军。该文在分析大白菜收获机工作特点的基础上，从大白菜的采摘、转运、打包等方面

进行分析。其中主要对输送部分做了详细的说明。该大白菜收获机适用于家用收割大白

菜，结构简单、制造成本低。

该大白菜收获机的输送部分采用带式输送，而张紧装置作为带式输送机构中不可缺

少的重要组成部分，对带式输送机的稳定运行有着至关重要的作用。本文首先介绍了张

紧装置的作用、类型，且设计了张紧装置的总体方案，对其主要零部件的设计和选型进

行了说明。所设计的张紧装置使用螺杆作为张紧执行元件，具有张紧力可调、结构简单、

适应性强、控制方便、安全性能好等特点。

Abstract

Farm machinery robot is to become the capital ship of the paper

introduced gathering ,transporting and packing cabbage,on the basis of the working

peculiarity of the cabbage harvest machinery,and it mainly introduced its transporting

mechanism. The cabbage harvest machinery is suitable to gather in the cabbage for family

expenses.

The cabbage harvest machinery use belt conveyors as its transporting mechanism,while

Tensioning device, as an important and indispensable component of the belt conveyor, has a

vital role to the stable operation of the belt conveyor . This paper introduces the role of the

tensioning device,type,installation layout principles, and its development then

raised the tension of the belt conveyor to the tension and take-up device requirements, on the

basis the analysis of the principle of the transmission belt conveyor. In this paper, the main

device design programme of the automatically tensioning device have been introduced, and

descripte its main components for the design and selection of the tensioning device

use the screwstaff as the take-up of the implementation component.,with adjustable tension,

simple, strong adaptability and control convenience, performance and safety and so on.
