the wheel surface of the pinch roller is convexly provided with a ground grabbing convex strip;

the plurality of press belt convex edges are arranged in the limiting ring groove in a protruding mode.

8. A seed tape pay-off device comprises a first mounting bracket, a belt wheel mounting mechanism and a belt pressing wheel mechanism, wherein the belt wheel mounting mechanism and the belt pressing wheel mechanism are mounted on the first mounting bracket; the method is characterized in that:

a belt releasing and feeding control mechanism is arranged on the first mounting bracket;

along the advancing path of the seed belt in the direct seeding operation process, the belt releasing progress control mechanism is arranged between the belt wheel mounting mechanism and the belt pressing wheel mechanism; the belt releasing process control mechanism is at least used for driving the clamping to release the seed belt on the opening and closing clamping mechanism.

9. A seed tape payoff device as claimed in claim 8, characterized in that:

the opening and closing clamping mechanism comprises a feeding driving wheel pair and is used for driving the feeding driving wheel pair to open or clamp; the belt releasing process control mechanism comprises a feeding driver which is used for driving the feeding driving wheel pair belonging to the clamping state to relatively rotate.

10. A seed tape pay-off device as claimed in claim 8 or 9, characterised in that:

a third mounting bracket and a clamping driver are mounted on the first mounting bracket, and a sliding bracket is movably mounted on the third mounting bracket;

the feeding driving wheel pair comprises a driving wheel which is rotatably arranged on the third mounting bracket and a driven wheel which is rotatably arranged on the sliding bracket; the feeding driver is used for driving the driving wheel to rotate; the clamping driver is used for driving the sliding support to reciprocate relative to the third mounting support along the clamping direction, so that the driven wheel mounted on the sliding support is close to or far away from the driving wheel matched with the driven wheel.
