A windrower coupled with a combine harvester

Abstract

The invention relates to a windrower hooked to a combine-harvester. A header of the vertical windrower is connected with a conveying mechanism of the combine-harvester through a middle connection mechanism, an integrated hydraulic system and an integrated controller are arranged on one side of the conveying mechanism of the combine-harvester, one end of a first oil cylinder executive feedback device is arranged on the middle connection mechanism, and the other end of the first oil cylinder executive feedback device is arranged on the header of the vertical windrower; one end of a second oil cylinder executive feedback device is arranged on the conveying mechanism of the combine-harvester, and the other end of the second oil cylinder executive feedback device is arranged on the combine-harvester; the first oil cylinder executive feedback device is connected with a first hydraulic control one-way valve, the first hydraulic control one-way valve is connected with an electromagnetic directional valve, and the second oil cylinder executive feedback device is connected with a second hydraulic control one-way valve; the second hydraulic control one-way valve is connected with a manual control directional valve, the integrated controller is connected with the first oil cylinder executive feedback device and the second oil cylinder executive feedback device, and a power transmission mechanism, a tensioning mechanism and an auxiliary mechanism are arranged on a rack. The windrower hooked to the combine-harvester is easy to operate, neat and orderly in laying, good in operation quality and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a windrower coupled with a combine harvester. Background technique [0002] Rapeseed is the main oilseed crop in my country. For a long time, the planting area and total output of rapeseed in my country have accounted for about 30% of the world's total. More than 30%. [0003] At present, there are two main types of mechanized harvesting of rapeseed: combined harvesting and segmented harvesting. Combined harvesting refers to the harvesting, threshing and cleaning of rapeseed at one time through the combine harvester at the late stage of rapeseed pods. High efficiency, labor-saving and other advantages, but due to the current stage of my country's rapeseed planting system is not uniform, varieties are diverse, related mechanical properties are not perfect, the harvest loss rate is high, farmers are unacceptable; segmental harvesting is when the rapeseed maturity reac...

[0003] At present, there are two main types of mechanized harvesting of rapeseed: combined harvesting and segmented harvesting. Combined harvesting refers to the harvesting, threshing and cleaning of rapeseed at one time through the combine harvester in the later stage of rapeseed pod ripening. High efficiency, labor-saving and other advantages, but due to the current stage of my country's rapeseed planting system is not uniform, varieties are diverse, related mechanical properties are not perfect, the harvest loss rate is high, farmers are unacceptable; segmented harvesting is when the rapeseed maturity reaches 75- In the early stage of 80% of the yellow ripening, the rapeseed is first cut or cut and bundled, and then dried in the field or in the field. After the post-ripening maturity reaches 90%, the mechanical threshing or the combine harvester with a pick-up device is used for threshing and separation. Cleaning operation, strong adaptability, make full use of the post-ripening effect of rapeseed, harvest in advance, prolong the harvest period as a whole, and help to increase the workload of a single machine and reduce the loss rate of harvest

[0004] The windrowing machine is the main tool in the windrowing stage of the segmented operation. The existing rapeseed windrowing machines can be roughly divided into two categories. One is the self-propelled small rapeseed windrowing machine. The wheat windrowing machine is transformed from a prototype, powered by a small walk-behind tractor. This type of rapeseed windrowing machine has a simple structure and low power consumption, but it needs manual operation. The operator's labor intensity is high and the work efficiency is low, so it is difficult to meet multiple demands. The work requirement of "grabbing the time" and fast operation under cooked planting conditions; another type of rapeseed windrowing machine has been developed in recent years in response to the development needs of rapeseed production. On the harvester chassis, most of these rapeseed windrowing machines use horizontal headers, which have the disadvantages of large size, too long body length, inconvenient hooking, complicated mechanism, poor mobility, and difficulty in adapting to small field operations in southern regions.
