Device suitable for combined harvesting of sesame

Abstract

The invention discloses a device suitable for combined harvesting of sesame. The device comprises a harvesting machine, a header, a material coiling device, a supporting device and a collection curtain, wherein the header is arranged on the front side of the harvesting machine; the header is in a hopper shape, a collection cavity is formed in the header, the material coiling device is arranged inthe collection cavity, the supporting device is arranged above the header, the collection curtain is wound on the supporting device, and an opening of the collection curtain faces the side away from the harvesting machine. The material coiling device is located over the header, the projection, in the horizontal direction, of the side, away from the harvesting machine, of the material coiling device is 60-150 mm ahead of the side, away from the harvesting machine, of the header, the maximum distance between the material coiling device and the ground is 2 meters, and the minimum distance betweenthe material coiling device and the ground is 0.4 meter. The height of the supporting device is not lower than 2 meters; the collection curtain comprises a curtain fabric, a plurality of through holes and a plurality of filter screens. The technical problems are solved that in the prior art, sesame capsules are cracked, seeds fall off, and during mechanical harvesting, the sesame loss ratio is high.

Description

technical field [0001] The invention relates to the technical field of sesame harvesters, in particular to a device suitable for combined sesame harvesting. Background technique [0002] Sesame is one of the main traditional oil crops in my country. The mature sesame capsules are easy to crack and the seeds fall off. The sesame seeds are small and light, and the stalks are brittle and easy to break. After the wheel touches a mature and dry sesame plant, the seeds are easy to fall off from the capsule, resulting in a small number of sesame seeds falling into the header and a high loss rate. For harvesting machinery, the loss rate is an important indicator for judging the quality of a harvester One, it is impossible to replace manual harvesting with machinery. At present, there is no harvester on the market that can solve the problem of a large loss rate of harvested sesame. [0003] A semi-automatic sesame harvester proposed by Chinese patent CN107980335A has simple structure ...

Problems solved by technology

[0002] Sesame is one of the main traditional oil crops in my country. The mature sesame capsules are easy to crack and the seeds fall off. The sesame seeds are small and light, and the stalks are brittle and easy to break. After the wheel touches a mature and dry sesame plant, the seeds are easy to fall off from the capsule, resulting in a small number of sesame seeds falling into the header and a high loss rate. For harvesting machinery, the loss rate is an important indicator for judging the quality of a harvester One is that it is impossible to replace manual harvesting with machinery. At present, there is no harvester on the market that can solve the problem of high loss rate of harvesting sesame

[0003] A semi-automatic sesame harvester proposed by Chinese patent CN107980335A has simple structure and convenient operation, and can replace manual harvesting of sesame stalks, which not only reduces labor intensity, but also improves sesame harvesting efficiency. However, when the lever device group and the cutting device of this device are in contact with the sesame plants, the sesame capsules are shaken, and the sesame seeds are cracked, resulting in very few sesame seeds falling on the conveying device, and the loss rate is extremely high.
