Study Of Framework And Parameter Of Film Mulching Hill-Drop Planter

Plastic film is a modernization planting technique in droughty and semiarid area, it is adapted to wheat, cootten, corn, peanut and so on. Plastic film can save water, protract crop's vegetal time, increase production.The test study 2BFXL-1 style of film mulching hill-drop planter, the purpose is to solve the problem between plastic film and hill-drop planter, We study in-depth about hill-drop planter is to perfect mechanization of farming, let it fit for diffent area and diffent crops.The test mostly analyse the film mulching hill-drop planter from two aspects: One is mechanism of duck-mouth type punching-opener, One is analyse of metering device .The test study the hole's forming and movement of duck-mouth type punching-opener, optimze the technic parameter of hill-drop planter: the duck-mouth figure, size, direction, rotary table radii , puncher length , and marching speed . Seed-metering device continuously supply seeds to hole former , utilize rotary table subareaing and distrubiting seeds, hole former intermissionly put in seeds.The new-style 2BFXL-1 having these strongpoints: frame briefness , having little power , little traction resistance,fitting small four tyre tractor.The theoretical analysis andexperiments shows that this machine have many functions, for example, favourable mulching stiletto and seeding,it can notability increase upper temperature,reduce the uppe water's lapse .It basically suffice crop for farming machine.
