Description

Technical Field

[0001] The utility model relates to the field of melon-picking machines, in particular to a weeding device for a harvesting platform. Background Art

[0002] Combine harvester for melons and gourds, also known as combine harvester, is a combined machine for harvesting gourds, melons and other crops. It is a harvesting machinery that can complete the processes of harvesting, threshing, separating stems, and removing debris of melon crops at one time and obtain grains directly from the field.

[0003] Traditional weeding devices mostly use mechanical combing to separate weeds and crop residues from crops through rotating comb teeth or rollers. However, when dealing with crops such as melon vines that have long vines and are easy to entangle, many problems are often encountered.

[0004] Especially in the application scenario of melon harvesters, due to the growth characteristics of melon vines and the complexity of different terrains and working environments, traditional weeding devices often cannot effectively deal with the entanglement and accumulation of melon vines. The entanglement of melon vines will not only hinder the combing mechanism of the harvester, affecting the weeding effect, but may even damage the key components of the harvester, reducing work efficiency and safety. At the same time, the accumulation of melon vines will also increase the workload of cleaning and maintenance, further reducing work efficiency. Utility Model Content
