Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of swathing machines, in particular to a front-hung chain-pulling finger type rape swathing machine. BACKGROUND

[0002] Mechanical harvesting of rapeseed mainly includes two ways: segmented harvesting and combined harvesting. Compared with combined harvesting, segmented harvesting is not sensitive to crop maturity and consistency, has strong adaptability, long suitable harvesting period, low loss rate and high yield, especially in rainy weather. Therefore, segmented harvesting has a good prospect for the diversity of plants and the unsuitability of varieties in China. Swathing operation is the primary key technology for segmented harvesting, and the swathing machine also has a good market.

[0003] In the existing technology, there are mainly two types of rape swathing machines. One type is a middle-laid rape swathing machine equipped with a high-clearance wheeled tractor or a tracked vehicle as a power chassis. The laying method is end-to-end overlap laying, which has good ventilation. The other type is a side-laid rape swathing machine hung on a tracked combined harvesting chassis, which is parallel laying and not easy to be compacted by the machine, and is convenient for pickup. Chinese Patent Application (Publication No. CN103416152A) discloses a front-hung middle-laid rape swathing machine on a high-clearance tractor, which adopts a hydraulic drive method. The cut-down rape stems are transported to the middle through a conveying belt and a vertical roller device under the support of a weeding wheel and are laid on the middle channel. However, this machine has a too long longitudinal size and a too large turning radius, which causes operation difficulties in the field. Chinese Patent Application (Publication No. CN110547089A) discloses a tracked self-propelled backpack type rape swathing machine. The laying device is inclinedly arranged on the front half of the track, and the middle of the machine is left empty as a rape swathing laying channel, which greatly shortens the longitudinal size. However, it needs to be matched with a special chassis, which has poor universality and high cost. Chinese Patent Application (Publication No. CN114246056A) discloses a wide-width foldable rape swathing machine based on a tracked power chassis. The machine uses a foldable middle-laid swathing table to realize wide-width operation and narrow-width transportation, which improves work efficiency. However, it is difficult to be applied to small fields in China due to its too large size and inconvenient operation. Chinese Patent Application (Publication No. CN110731168A) discloses a small-sized hand-held single-side rape swathing machine. The height between the swathing table and the track is adjusted by a height adjusting mechanism. The cut-down rape is laid on the outside of the machine under the action of a horizontal conveying device. However, it needs to be manually pushed forward, which has a large labor intensity. In addition, it is not suitable for lodging rape. SUMMARY
