地膜覆盖在水果和蔬菜的生产中显示出巨大的优越性。但是,从田间清除地膜却是一项很艰难的工作。现在生产中虽有一些回收机具在应用,但却未实现自动化。一种可以把地膜自动卷起的试验样机已经被研制完毕.并在田间进行了演示。该装置在拖拉机行走速度或卷膜滚商直径发生变化时,能通过扭矩传感装置使卷膜线过度与拖拉机行走速度保持同步。在拖拉机停止和起步时也不需要任何手动控制。该装置还可以使卷满后的地膜很方便地从卷股滚筒上卸下。
Mulch shows great advantages in the production of fruits and vegetables. However, removing the plastic film from the field is a very difficult task. Although some recycling machines are in production nowadays, they are not yet automated. A test prototype that automatically winds up the film has been developed. And conducted a demonstration in the field. The device is capable of keeping the film roll line in synchronicity with the tractor travel speed via the torque sensing device as the tractor travel speed or winding roll diameter changes. There is no need for any manual control when the tractor stops and starts. The device also makes it easy to remove the rolled film from the take-up roller.
