Telescopic dental formula residual film gathering method and mechanism of non-circular gear planets

Abstract

The invention discloses a telescopic tooth type remnant film collecting method of a non-circular gear planetary system and the mechanism thereof. The two ends of a remnant film collecting roller are respectively fixed with a set of non-circular gear planetary system box body in which a non-circular inner gear, a center sun non-circular gear and six planetary circular gears are provided; the non-circular inner gear is in an inner mesh with the planetary circular gears which are in an outer mesh with the center sun non-circular gear; the six groups of in-phase planetary circular gears in the box body at the two ends of the roller are respectively fixed and connected with six planetary circular gear shafts; six groups of film collecting teeth and rod components are arranged on the radial direction, in each group of film collecting teeth, six film collecting teeth which are evenly distributed along the axial direction are provided, one end of the film collecting teeth is movably sleeved on the centers of the planetary circular gear shafts, and the middle parts of the film collecting teeth are movably sleeved on a film collecting tooth shaft. When in work, the mechanism is driven by the roller, the rotation and the revolution of the planetary gears are driven through the rotation of an inner gear, the middle sun gear is fixed to control the protruding and the retractation of the film collecting teeth, the film collecting requirement is met.

Description

technical field [0001] The invention relates to a residual film pickup machine, in particular to a telescopic toothed residual film pickup method and mechanism of a non-circular gear planetary system. Background technique [0002] The film mulching technology increases the limited accumulated temperature and prolongs the growth period relatively. The middle and late-maturing varieties can be widely used, which greatly increases the yield. At the same time, the suitable cropping areas of various crops can be moved northward and expanded, which can make more effective use of land resources. However, the agricultural plastic film is extremely difficult to degrade under natural conditions, and the residual film accumulates in the soil, causing serious pollution of the agricultural environment, destroying the ecological environment of the farmland, forming a barrier layer, and affecting the absorption of water and nutrients by crops. Seeds germinate and emerge, causing rotten se...

Problems solved by technology

The film-picking elastic tooth type residual film recycling machine and the eccentric roller type picking mechanism both use a cam slide to control the track and posture of the film picking teeth to complete the film picking and stripping, and the cam wear is serious
