Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a residual film recycling machine. Background Art

[0002] Film mulching cultivation technology is an advanced cultivation technology that improves and optimizes cultivation conditions, overcomes the influence of adverse conditions and achieves early maturity, high yield and high efficiency. It is widely used at home and abroad. However, there are some adverse effects in film mulching cultivation, such as long-term film mulching, residual film is not cleaned up, causing soil pollution, due to the rapid decomposition of organic matter after film covering, high crop utilization rate, less fertilizer supplementation, and the decline of soil fertility. Improper management of film covering can also cause early maturity without increasing production, or even a reduction in production. Therefore, the timely recovery of residual film is an important link, among which mechanical picking up is the best method.

[0003] Most of the existing residual film recycling machines with rollers have a structure of telescopic teeth in the roller. When the film shovel scoops up the residual film, the telescopic teeth grab the residual film as the roller continues to roll, and then a separate film scraping or film elastic device peels the residual film from the telescopic teeth into a film collection box. However, when the residual film is recovered by the telescopic teeth, the residual film is easy to attach and entangle on the telescopic teeth. During the continuous operation of the telescopic teeth, more and more residual film will be entangled on the telescopic teeth, which is easy to jam the telescopic teeth and make the telescopic teeth lose the ability to collect film. Manual removal of residual film is often required, resulting in low efficiency of residual film recovery and inability to work continuously. In addition, the recovered residual film contains a large amount of soil, which seriously affects the recovery effect of the residual film and brings great difficulties to the bundling of residual film.
