Description
Technical Field
The utility model relates to a sawtooth stalk-pulling roller structure of a corn machine.
Background
The corn harvester mainly comprises a header, an elevator, a peeler, a ear box and the like, wherein the header is mainly responsible for feeding and ear picking functions, and the harvest performance of the whole harvester is directly determined by the quality of the header performance, so that the corn harvester is a key part of the whole harvester. The stalk pulling roller is one of important parts for separating corn stalk from ear, and the stalk pulling roller is driven to rotate relatively with the ear picking box. The reasonable stalk pulling roller structure can effectively take stalks away, and then the stalks are subjected to subsequent treatment by the chopping device, so that the stalks can be prevented from entering the elevator and the peeler, the load of the part is increased, a good harvesting effect is realized, the cutting table is prevented from being blocked, and the transmission device (chain, gear and the like) is damaged.
The existing stalk pulling roller is of a six-edge structure generally, the roller body is formed by welding a connecting shaft, cones, edge plates and connecting sleeves, 6 edge plates are distributed in a hexagonal shape and are main working parts of the stalk pulling roller, but because the stalk pulling roller is formed by welding, more plug welding holes are needed on the edge plates for guaranteeing strength, on one hand, the welding amount is large, on the other hand, thicker plates are needed for the edge plates, the required size is difficult to achieve after processing, the roller body of the stalk pulling roller is smooth, stems with large moisture are encountered during working and are easy to slip, and the grabbing capacity of the stems is poor, so that cutting tables are blocked.
Disclosure of utility model
The utility model aims to solve the defects in the prior art and provides a sawtooth stalk-pulling roller structure of a corn machine.
The utility model provides a corn machine sawtooth draws stem roller structure, includes connecting axle, connecting pipe, taper sleeve, a plurality of arris board, adapter sleeve, the connecting pipe be hollow structure, the connecting pipe cup joint on the connecting axle, the taper sleeve cup joint the front end at the connecting pipe through the welding, the adapter sleeve cup joint the rear end at the connecting pipe through the welding, the lateral wall of connecting pipe on be equipped with a plurality of mounting grooves along axial circumference equidistance interval, the arris board be platelike structure, the arris board peg graft in the mounting groove to through welded fastening.
Working principle: through processing the mounting groove on the lateral wall of connecting pipe, fix a plurality of arriss boards in the mounting groove through the welding, form the roll body, overall structure is simpler, and easy processing, and make more firm that the arriss board was installed through pegging graft in the mounting groove, can not rock, also more convenient welding.
In order to improve the grabbing force of the stalk pulling roller, the outward edge of the prismatic plate is provided with a sawtooth structure which is a trapezoid sawtooth structure.
In order to play a guiding role, the front end of the prismatic plate is provided with an inclined surface chamfering structure.
In order to facilitate the connection of the edge plate and the connecting sleeve, the whole mechanism is more reasonable and attractive, a notch matched with the connecting sleeve is arranged at the lower end of the rear end of the edge plate, and the edge plate is in lap joint with the connecting sleeve and fixed through welding.
The beneficial effects are that: compared with the prior art, the utility model has the advantages that the installation groove is processed on the outer side wall of the connecting pipe, the plurality of edge plates are fixed in the installation groove by welding to form the roller body, the whole structure is simpler and is easy to process, the edge plates are more firmly installed by being inserted in the installation groove, the vibration is avoided, and the welding is more convenient;
Meanwhile, after the serrated prism plates are adopted, the grabbing capacity is enhanced, the stalks and the clusters can be effectively separated, the stalks are prevented from entering a subsequent device, the stalks with larger moisture can be easily taken away when the device runs into the stalks, and the blockage is prevented.
