Automatic ridge walking device of tobacco harvester

Abstract

The invention relates to an automatic ridge walking device of a tobacco harvester. The automatic ridge walking device comprises a machine frame, a walking system, a tobacco leaf collection box, a seat and a detection control system. The walking system comprises a hub motor and a motor drive system. The detection control system comprises infrared ranging sensors, a single-chip microcomputer and a D / A conversion module. The two infrared ranging sensors are movably fixed to the two sides of a sensor support and connected to the A / D collection port of the single-chip microcomputer. The I / O port of the single-chip microcomputer is connected with the D / A conversion module. The output port of the D / A conversion module is connected with the signal control end of the motor drive system. An output shaft of the motor hub is fixed to a hub fixing base below the machine frame. The distances between wheels on the two sides and a tobacco ridge can be accurately detected through the infrared ranging sensors, data obtained through the sensors are transmitted to the single-chip microcomputer, and the automatic steering is achieved.

Description

(1) Technical field [0001] The invention provides an automatic walking device on a ridge of a tobacco harvester, which belongs to tobacco field management machinery. (2) Background technology [0002] Tobacco is one of the main economic crops in our country, and growing tobacco has become an important part of increasing farmers' income and fiscal taxation. During tobacco harvesting, the transportation of tobacco leaves in the field is a very heavy task because there is no special transportation route in the tobacco field. Most of the tobacco leaves harvested in our country are transported manually in the field. Even in some places with a high degree of automation, manually driven tobacco harvesters are used. Therefore, the development of the automatic walking device on the ridge of the tobacco harvester is an effective measure to reduce the work intensity of the tobacco farmers, and it is also a major problem to be solved urgently in the current tobacco production.
