Description

Technical Field

[0001] The utility model mainly relates to the technical field related to agricultural machinery, and specifically is a seedling removing device for a gourd harvester. Background Art

[0002] The gourd harvester is mainly used for harvesting seeds of gourds, melons, seed melons and other melons. It can harvest various melon crops growing on the ground. During the harvesting process, the gourd harvester mainly uses the header at the front for harvesting. The harvesting shaft of the header has multiple melon picking teeth. When the harvesting shaft rotates, the gourds are picked up by the picking teeth and removed by the melon remover during the rotation. The fallen melons roll into the collection bin at the rear.

[0003] In the prior art, for example, a melon-throwing machine cutter structure (publication number CN220799132U) previously applied by our company has a seedling-pulling assembly disposed on the upper part of the cutter, and the seedling grass on the melon-pulling teeth can be pushed to the cutter conveyor belt in front when multiple sets of seedling-pulling rubber plates rotate. However, in actual use of the above-mentioned prior art, some of the longer seedling grass is not cut off, so it is difficult to be pushed forward by the seedling-pulling rubber plates, so the seedling grass is easy to accumulate and get stuck. In the above-mentioned prior art, by arranging a fling knife at the rear of the cutter, part of the seedling grass can be cut off during the operation, so as to facilitate the subsequent weeding and seedling clearing operations. However, for the above-mentioned prior art, due to the limited force of the fling knife, part of the seedling grass is difficult to be cut off, so there is still a lot of seedling grass entering the upper seedling-pulling assembly, resulting in a large workload at the seedling-pulling assembly and a poor seedling clearing effect.
