Abstract:
     This invention is an earth covering machine for preventing seedlings from cold. It is mainly composed of such parts as suspension, framework, power driving and working. The machine is attached via the suspension to a tractor. The tractor outputs the power which is transmitted via main and side variable speed cases to the working part. The earth in walking channel is thrown onto seedbed by earth-breaking jaw, earth-covering shovel and earth-guiding cover and then scraped plain. Finally, the seedbed covered with earth is shaped by the side board of its shaper. Thus, the seedlings can safely survive the winter. This invention has the advantages of high efficiency, reliable working performance and no damage to seedling. Besides earth covering job, it can also be used to make the bed in nursery.
