Anti-moving clutch mechanism of direct seeding machine
Technical Field
The utility model relates to the technical field of agricultural machinery, in particular to clutch mechanism is prevented scurrying of living broadcast machine.
Background
Agricultural machinery refers to various machines used in the production process of crop planting and animal husbandry, as well as in the primary processing and treatment process of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil farming machinery, planting and fertilizing machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery, agricultural transportation machinery and the like. A seeding machine is a planting machine that takes crop seeds as a seeding target. Seeders for certain types or crops are often referred to by the name of the crop type, such as grain drill, corn hill planter, cotton planter, grass spreader, and the like. The direct seeding machine is a common device in agricultural machinery, and consists of a traction frame, a power system, a transmission system, a walking system, a direct seeding system and the like. Among the transmission system, the power of main shaft is passed to the traveling system on the one hand, and the live system is passed to on the other hand, and at the in-process that the direct seeder turned etc. do not sow the walking, the live system lifts up, and does not need the seeding, and the traveling system is to last work, this needs clutching mechanism to realize, but clutching mechanism on the direct seeder at present generally does not have the anti-channeling function, because reasons such as vibration and the unexpected separation that causes power easily at the in-process of direct seeder action, cause the live vacancy.
