Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesters, in particular to a novel stem pulling roller and a corn harvester. Background Art

[0002] Corn harvesters are widely used in corn harvesting operations. Plate-type corn harvesters are favored by operators and users for their wide adaptability, long operating time, and low grain loss. However, compared with roller-type corn harvesters, the plate-type models have significantly more debris (straw and husks) brought into the machine body from the header, and the rear end is occasionally blocked by straw. In order to reduce the entry of debris and blockage, the working device needs to be adjusted frequently during use, which brings many changes to users and reduces work efficiency. To solve this problem, it is crucial to study the structure of the stem pulling roller, a key component in the ear picking device, in order to improve the effective stem pulling formation and reduce the problem of channel blockage. Utility Model Content

[0015] The beneficial effect of adopting the above further solution is that the multiple rear end extensions and the sleeves are reasonably distributed, which can effectively prevent weeds and straw from being entangled and improve the harvesting efficiency.

[0016] Furthermore, a guide cone is fixedly connected to the front end of the roller, and the guide cone has a structure with a thin front end and a thick rear end, and the rear end is fixedly connected to the front end of the roller.

[0017] The beneficial effects of adopting the above further scheme are simple structure and reasonable design. The guide cone can be used to quickly feed the straw into the two stem pulling rollers during harvesting, so as to improve the harvesting efficiency.

[0018] Furthermore, the guide cone is a spiral guide cone.
