Abstract
Description
Technical Field
[0001] The utility model relates to the field of melon-beating machines, in particular to a grass-clearing knife used for a grass-clearing roller. Background Art
[0002] In agricultural harvesting machinery, the front header spike roller is an important part for collecting gourds or melon crops, but it often inevitably carries weeds such as melon vines during work. The removal of melon vines is usually done by a weed-clearing roller, which is usually equipped with rubber plates. These rubber plates will contact the melon vines carried by the spike roller during rotation and try to remove them through rotation.
[0003] However, in actual operation, melon vines often have long vines and leaves, which are easy to entangle and accumulate on the rubber plate of the grass cleaning roller. As time goes by, these accumulated melon vines will gradually increase, causing the rotation of the grass cleaning roller to be obstructed or even stop working completely, which not only affects the working efficiency of the harvesting machinery, but may also cause damage to the machinery itself.
