Technical Field

The invention belongs to the technical field of rakes, and particularly relates to a rotary control device of a rake.

Background

The rake is a grass harvesting machine which rakes grass scattered on the ground into grass strips. The purpose of raking is to fully dry the grass and facilitate the collection of hay. The rakes can be divided into two broad categories, transverse and lateral, according to the relationship between the direction of the swath and the direction of advance of the implement.

The working parts are a row of circular arc or spiral spring teeth which are transversely arranged side by side. During operation, the tips of the elastic teeth of the rake touch the ground, and grass cut by the mower is paved and raked into transverse swaths (namely, the swaths are vertical to the advancing direction of the mower). The grass strips are compact, so that the drying is not facilitated, and the grass strips are mixed with a large amount of impurities, are not neat and are not beneficial to subsequent operation. The operation speed is also low, generally 4-5 km/h. The size of the raked swath of the rake type can be manually controlled and is generally used for natural grasslands with low yield.

Rakes are typically controlled by mechanical drive control mechanisms, so a continuous cycle control mechanism is particularly important on rakes
