Crawler self-walking backpack type rape swather

Abstract

The invention discloses a crawler self-walking backpack type rape swather which comprises a pair of walking crawlers, a main machine frame, a cutting device, an auxiliary feeding and grain pulling device and a spreading device. The spreading device is obliquely arranged on the upper side of the front half portion of the walking crawlers towards to-be-harvested rape. The upper end of the spreadingdevice is installed on the main machine frame. The lower end of the spreading device is fixed to the cutting device. By using a frame and the spreading device in cooperation, emptying the middle of the machine to form a rape swathing and spreading channel and cutting off rape through a cutting and conveying device and then gathering the rape to the middle to be backwards spread, the conveying distance of the cut-off rape is reduced, and the conveying efficiency is improved; before operation, there is no need to form a way manually, rape stubbles in the middle spreading area are not rolled, itis ensured that plants are spread on the stubbles to be aired overhead without making contact with damp soil, light permeability and breathability are realized, after-ripening is facilitated, and subsequent mechanical picking and harvesting are facilitated.

Description

technical field [0001] The invention belongs to the technical field of segmented harvesting in agricultural machinery, and in particular relates to a caterpillar self-propelled knapsack windrower for rape. Background technique [0002] Rapeseed is the largest oil crop in my country. In recent years, the planting area has exceeded 100 million mu, of which the planting area of ​​winter rapeseed in the Yangtze River Basin accounts for 90%. Domestic rapeseed oil accounts for more than 55% of the oil production of domestic oil crops, and the development of rapeseed production has important strategic significance for maintaining the national edible oil supply security. However, in recent years, due to the market impact of the transfer of rural labor force, low mechanization, high labor costs, and the import of low-priced rapeseed, rapeseed planting benefits are low, and industrial development is facing tremendous pressure. The No. 1 Central Document in 2019 clearly pointed out th...

Problems solved by technology

For example, the Chinese patent application number 2012510559271.1 discloses a windrower suitable for rapeseed harvesting, with a working width of 1.85 meters and full hydraulic drive. Functional components such as cutting, conveying, laying and reel are suspended before the header. Hooked on the power machine, the rapeseed is transported to the middle under the joint action of the conveying and laying device after being cut down. However, due to the rotation of rice and oil in the Yangtze River Basin, rice planting is soaked in water for a long time in summer and autumn, and rape planting in winter and spring has a lot of rain, and the fields are muddy. The soil is deep, the soil is sticky and heavy, and the equipment is equipped with a front suspension. There are problems such as large front wheel load, easy to get stuck in the operation, large turning radius in the field, and insufficient passability of the equipment.

The Chinese patent application number 201420571400.3 discloses a small crawler-type rapeseed windrower, which adopts a crawler-type walking chassis, which improves the operability and maneuverability, but the implement still adopts front suspension transfer, and the windrower mainly uses side Side laying, that is, the row of crops is on the side of the cutting platform, and the plants are transported to the laying side after cutting. The operation needs to be cleared in advance, and the plant transportation distance is long, which may easily cause blockage of the conveying device and disorderly laying

The Chinese patent application number 201520074744.8 discloses a rapeseed windrowing machine, which adopts a crawler-type walking chassis, which is flexible in operation and has good adaptability to the terrain. The rear of the tool is laid, and the plant transportation distance is longer, which increases the disorder of plant laying and is easy to block
