Abstract:

In order to solve the problem of lower the labor intensity of manual removing tobacco stalk or incompletely removing tobacco stalk and root out field, to meet the demand of the coming year tobacco cultivation. Through theoretic analysis and experimental exploring, supporting DF-151 or GN-121 type walking tractor YS-YGQ-1A-type cleaning machine for tobacco stalk has been developed. This machine use the forward employment by riding ridge, pull up the stalk by the roots by means of reversely digging, transport the stalk to collecting-hoppers by transportation rotor and remove the adherent soil by vibration, then centralized the stalk dump on field. The performance test and experimental verification showed that this machine had relatively strong field passing capacity. Its various performance indicators were to meet the design requirements and meet the agronomic requirements of tobacco. Its operating efficiency was 0.91 hm2/8 h and also had a stable property, and could significantly increase productivity, significantly lower labor intensity and activity cost, and could reduce stalk pulling after tobacco field rotary tillage cost.
