Description

Nail-pricking roller for seed cotton cleaning machine Technical Field The utility model belongs to the technical field of seed cotton cleaning, and particularly relates to a spike roller for a seed cotton cleaning machine. Background The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. In the cotton processing process, the spike roller assembly is a key piece used on a seed cotton cleaning machine and an opening seed cotton cleaning machine and generally consists of a spike roller tube shaft and a spike. The barbed nails on the barbed nail roller assembly are directly welded on the tube shaft of the barbed rolls, and in the seed cotton cleaning process, the agglomerated seed cotton contains a large amount of large impurities and hard impurities due to the high rotating speed of the barbed nail roller, so that the barbed nails fall down or fall down. The current spike roller is easy to be impacted by impurities, so that the spike on the spike roller is dropped or loosened, the impurity removing effect is affected, and when seed cotton is cleaned, the spike roller is easy to be stuck with large impurities and hard impurities, the use of the spike roller is affected, and the impurity removing efficiency is difficult to be ensured. Disclosure of utility model Aiming at the problems, the utility model provides the spike roller for the seed cotton cleaning machine, which can improve the spike strength on the spike roller, avoid lodging or falling of the spike in the use process, avoid the impurity from being blocked on the spike roller and ensure the impurity removing effect and the impurity removing efficiency. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The spike roller for the seed cotton cleaning machine comprises a spike mechanism and a spike roller tube shaft, wherein the spike mechanism comprises a first spike component, a second spike component and a third spike component, the first spike component, the second spike component and the third spike component all comprise spikes and spike supporting pieces, one ends of the spikes are provided with the spike supporting pieces, the spike supporting pieces are fixedly connected with the spikes, the bottom surfaces of the spike supporting pieces are arc surfaces, and the bottom surfaces of the spike supporting pieces are attached to the surface of the spike roller tube shaft. Further, the first spike component is symmetrically arranged by taking the axis of the licker-in pipe shaft as the center, and a plurality of spikes of the first spike component are arranged at intervals along the radial direction of the licker-in pipe shaft. Further, the second spike component is symmetrically arranged by taking the axis of the licker-in pipe shaft as the center, and a plurality of spikes of the second spike component are arranged at intervals along the radial direction of the licker-in pipe shaft.
