Small creeping type peanut digging and harvesting machine for film-covering planting

The present invention relates to a peanut harvesting machine. A small creeping type peanut digging and harvesting machine for film-covering planting is provided. A tip forward digging shovel (2) is horizontally disposed at a lower end of a front end a rack; a toothed conveyor chain (3) that is from a lower and front position to a rear and upper position is disposed on a rear crossbar that is from the digging shovel (2) to a rectangular rack; a guide plate (4) is disposed a rear part at each of two sides of the toothed conveyor chain (3); a pair of toothed revolvable cylindrical barrels (7) are configured between the two guide plates (4): the toothed revolvable cylindrical barrels (7) are metal ring gears that extend from an outer surface of the cylindrical barrels and that are perpendicular to an axis; and each ring gear is a triangular toothed plate that extends out along a circumference; surfaces of ring gears are covered by a rubber coating; and a left reversible plate and a right reversible plate (8) are disposed at the rear of the toothed revolvable cylindrical barrels (7), and the upper surface of the reversible plate (8) extends backwards and moves downwards and passes through a rotatory structure to smoothly turn the upper surface downward. According to the present invention, disadvantages of domestic film-planting in the prior art comprising winding, bar clipping, fruit clipping are overcame, and advantages of large-scale mechanical harvesting can be realized.
