Description

Twin-shaft straw crushing and mulching film recycling combined machine

Technical field

The invention relates to the field of agricultural machinery, and in particular to a twin-horizontal-shaft straw crushing and mulching film recycling combined operating machine.

Background technique

At present, the application of mulching film planting technology has been very common, bringing huge benefits to agriculture. However, the residual film remaining in the land has also become a serious problem, which has also brought great pollution and harm to the soil and the environment. The soil is white because of its white color. Pollution hinders the growth of crops and seriously loses their ability to support them. On the other hand, along with the application of mulching film planting technology, crushing and returning straw to the field is also an important technical measure. Therefore, at the end of a crop planting season, there are often The plastic film recycling and crop straw crushing and return to the field are carried out at the same time.

There are two modes of recycling mulch film and crushing and returning crop straw to the field, step-by-step and synchronously. However, in the actual operation of either mode, the straw is cleaned and crushed first, and then the mulch film is recycled. Existing machinery is used in When cleaning and crushing straw, part of the mulch film will be more or less rolled into the crop straw, making it difficult to recycle the mulch film.

Although there are a variety of combined straw crushing and returning to the field and mulch recycling machines on the market, the actual use results are not ideal. The main reason is that after the crops are harvested, the straw needs to be crushed and returned to the field. The existing equipment is to crush the crushed straw to the field. One side of the combined working machine is returned to the field. As a result, the crushed straw is returned to the field in strips. If the crushed straw is thrown to the rear, it will affect the operation of recycling the mulch film.

In addition, mulch film recycling mainly uses scoops or scoops to pull the mulch out of the ground and then recycles it. After the current scoops or scoops lift up the mulch, it will accumulate at the picks or scoops. , after walking for a certain period of time, you need to stop and clean the mulch film accumulated at the clenching teeth or film lifting shovel, and then work again. The disadvantage of this is that the work efficiency is low, and the mulch film accumulated at the cuffing teeth or film lifting shovel is removed. , it needs to be cleaned separately again. Chain rakes or roller-type film collecting components can easily cause the film to wrap around and rewind. Film stripping is a common problem in current residual film recycling machinery.

Therefore, a twin-horizontal-shaft straw crushing and mulching film recovery combined operation machine that is easy to use and can crush straw and return it to the field and recover residual film in one go is proposed.
