Soil removal pulling bar device

The invention provides a soil removal pulling bar device, relating to the agricultural machinery; the device is composed of a travelling mechanism, an inversion mechanism, a pulling bar upper clamp mechanism and a soil removal downward-scraping mechanism; the inversion mechanism is composed of a main driven shaft sheathed on a U-shaped frame at the middle part of a beam and a main driven gear, the upper clamp mechanism is composed of an electrician's clamp shaped binding clip, a clamp level and an upper rotational sleeve, a main driving shaft of the inversion mechanism is connected below the middle part of a right clamp level by an upper rotational sleeve; the soil removal downward-scraping mechanism is composed of a binding clip below the upper clamp mechanism, a tubular clamp level, a lower rotational sleeve and a synchronization ring, the clamp head is formed by distributing two semi-circle rings of a plurality of radial cutters in the ring, the outer end part of the clamp level at the right part is fixed
