Abstract
The utility model discloses an anti-twisting device of a maize threshing machine roller, which consists of a roller, an upper shell, a ball bearing seat, a bolt, a protective shaft sleeve and a rotating shaft; the protective shaft sleeve is arranged between the upper shell and the end surface of the roller and is fixed on the ball bearing seat and the upper shell by the bolt; and the protective shaft sleeve is shaped like a round groove, with the groove width more than the outer diameter of the roller. The roller is deep in the groove of the protective shaft sleeve along the axial direction and a clearance of 5mm is reserved between the end surface of the roller and the groove bottom of the protective shaft sleeve. The anti-twisting device has the advantages that the groove-type design of the protective shaft sleeve can well obstruct the sundries that are easy to twist the rotating shaft and the ball bearing seat in the maize threshing machine, the abrasion of the rotating shaft and the ball bearing seat is greatly reduced and the service life of the anti-twisting device is effectively prolonged.
Description
Technical field
The utility model relates to a kind of novel corn thresher, belongs to agricultural mechanical field, specifically corn threshing machine cylinder anti-wrap device.
Background technology
Corn is in all staple foods; its nutritive value and health-care effect are the highest; can be used as uses such as human grain ration, animal feeding-stuff and industrial production raw material substantially; so cultivated area is very big; in today that agricultural production progressively develops; in conjunction with the condition of production of China's reality, some full-automatic or automanual husker shellers enter common rural households more and more, play important impetus in agricultural development.But used husker sheller exists the easy twisting shaft of the corn ear of belt leather more; cause cylinder can't operate as normal etc. problem, in addition because the working environment of thresher exists more dust and maize cob sheet etc.; the wearing and tearing of its rotating shaft and bearing are also relatively more serious, reduced its service life!
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and provides a kind of simple in structure, and long service life can effectively be avoided the corn threshing machine cylinder anti-wrap device that twines.
The technical solution of the utility model realizes in the following manner: corn threshing machine cylinder anti-wrap device; by cylinder; upper shell; ball bearing housing; bolt; protective shaft sleeve and rotating shaft are formed, and it is characterized in that: described protective shaft sleeve is between upper shell and cylinder end face, and it is by being bolted on ball bearing housing and the upper shell.Protective shaft sleeve is the circular groove shape, and its groove width is greater than the external diameter of cylinder.Cylinder gos deep in the groove of protective shaft sleeve vertically, and its end face and protective shaft sleeve bottom land leave the gap of 5mm.
Its advantage is: the groove type design of protective shaft sleeve can intercept the interior countershaft easily of husker sheller well and ball bearing housing produces the foreign material that twine, and significantly reduces the wearing and tearing of rotating shaft and ball bearing housing, has effectively prolonged its service life.
