<P>PROBLEM TO BE SOLVED: To simultaneously dig out field crops such as potatoes and perform seeding of a cover crop. <P>SOLUTION: An earth screening conveyer 2, the front end of which has a hoe 3, is mounted to a traveling machine body with a stoop, and a hopper 4 storing seeds S is provided on the traveling machine body. A discharge opening 6a is provided to discharge the seeds S on the earth raised at the forward end of the earth screening conveyer 2. When the hoe 3 is buried in the ridge ground G and the traveling machine is travelled, the field crop P in the earth is picked up while some of the ridge ground G is raised to the forward end of the earth screening conveyer 2 by the hoe 3. The dug out field crop P is picked up by the earth screening conveyer 2, and adhering earth is shaped off by the earth screening conveyer 2. Simultaneously with digging out and picking up, the seeds S in the hopper 4 is discharged on the raised earth, and the seeds S and the earth are mixed by the earth screening conveyer 2 and also fallen in the ridge ground G. <P>COPYRIGHT: (C)2013,JPO&INPIT |
