Description

Earthing device on membrane Technical Field The invention relates to the technical field of agricultural machinery, in particular to a film soil covering device. Background In order to ensure the normal emergence of peanut seedlings, the peanut is required to be covered with a film and earth is covered on the film during sowing. The structure of the existing soil covering equipment on the film is shown in fig. 1 and 2, and comprises a frame 1, a film roller 2, a soil covering disc 3 and a soil covering cylinder 4, wherein the film roller 2, the soil covering disc 3 and the soil covering cylinder 4 are all arranged on the frame 1, and a film roll is arranged on the film roller 2. When the frame 1 moves, the soil covering disc 3 scrapes the ground soil into the soil covering cylinder 4, and the soil falls on the mulching film after moving out of the soil covering cylinder 4 to realize soil covering.
