Description

Technical Field

[0001] The utility model mainly relates to the technical field of agricultural machinery, in particular to a gourd harvester. Background Art

[0002] The gourd harvester is mainly used for harvesting the seeds of gourds, gourds, 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 front header for harvesting. After the header is harvested, it is sent to the melon cutting structure to break the melons and fruits, and then sent to the threshing chamber to separate the seeds.

[0003] In the prior art, gourd harvesters often have the following defects: 1. A melon separator is generally installed on the header of the gourd harvester for dividing rows and picking melons. The connecting assembly between the melon separator and the header bracket is generally arranged at the lower part, which makes it easy for the melon vines to be entangled with the melon separator, which is not conducive to the normal operation of the melon separator; 2. During the operation of the harvester, stones carried by the header are easily splashed to the cab position, resulting in bumps and damages to the cab glass; 3. There is a cutting knife in the melon cutting room for crushing melons and fruits. If the stones carried by the melons and fruits are not discharged in time, it is easy to cause the cutter to The knife is damaged. The existing stone discharge structure (such as our company's previous publication number CN221104145U, named "Related Technology of a Feeding and Discharging Mechanism of a Melon Thrasher") realizes stone discharge by connecting the sealing plate of the elastic opening and closing component. However, the sealing plate is arranged at the specially arranged discharge port at the rear of the feed box. During the stone discharge process, it is affected by the lower baffle of the discharge port, resulting in some stones not being discharged in time; 4. The separation chamber of the gourd harvester generally adopts an integral cover-type structure. When the threshing chamber needs maintenance and repair, it needs to be completely disassembled, which is cumbersome and labor-intensive. Utility Model Content
