Description
It is mainly used for sowing of small seeds such as grains, vegetables, pastures, etc. Commonly used are grain drills. During the operation, the walking wheel drives the seeding wheel to rotate, and the seeds from the seed box are discharged into the seeding pipe according to the required seeding amount, and fall into the opened groove through the opener, and then are covered by the soil suppression device Cover and compact the seeds. After emergence, the crops are arranged in parallel and equidistant rows. The seed drills for different crops are basically the same in structure except for different types of seeders and ditchers. It consists of an opener, a row marker, a walking wheel, and a soil-covering and cracking device. Among them, the seeding device and the opener mainly affect the seeding quality. Commonly used seed metering devices include groove wheel type, centrifugal type, and grinding disc type. Openers are available in shovel type, shoe type, sliding knife type, single disc type and double disc type..
Agricultural machinery transmission shaft (PTO Drive Shaft) is used in modern agricultural machinery power transmission, the most common between tractor and agricultural machinery or agricultural machinery itself between the power output and input power transmission, so that agricultural machinery to achieve the effect of normal work. At the same time, the shaft has the characteristics of universal transmission, the input end and the output end can not be in the same plane according to different types, the structure of the agricultural machinery drive shaft can make the Angle between the output end and the input end reach 0-80°, in the working process can be telescopic in the specified range.
