Furthermore, a conveying belt structure is arranged in the feeding groove, a safety space is arranged on the lower surface of the inclined slide way part of the material return preventing plate, the bottom surface of the safety space is the surface of the conveying belt, the running direction of the conveying belt is in the safety space, and the lower surface of the inclined slide way part of the material return preventing plate is a smooth surface. The safety space is used for when the material blocks up, and the material can be extruded into this space temporarily, and after the material in front left, the conveying force of conveyer belt structure can take it out, has avoided the jam of operation.
Furthermore, the anti-return plate is formed by bending a plate, and the parts of the two sides of the anti-return plate, which are connected with the elastic plate, are in welded connection. The anti-return plate is simple to process and easy to adapt.
Further, the spikes on the licker-in are welded and fixed on the peripheral surface of the licker-in.
Compared with the prior art, the utility model, have following advantage and effect: the device is used in an agricultural machinery structure, has the effects of improving the production efficiency and the operation stability, avoids mechanical faults in the working process and prolongs the service life of machinery.
