Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b):

referring to fig. 1 and fig. 2, the present invention provides a technical solution:

the utility model provides a conveying roller, includes pivot 1, cylinder face 2, flexible connection board 3, stop gear 4 and threaded sleeve 5, wherein:

the plurality of roller surfaces 2 are respectively arranged on the outer side of the rotating shaft 1 to form a roller in a surrounding manner, two adjacent roller surfaces 2 are respectively connected through a flexible connecting plate 3, the flexible connecting plate 3 is fixedly connected with the roller surfaces 2, the flexible connecting plate 3 can elastically deform under the action of external force, so that the distance between the roller surfaces 2 can be changed, the diameter of the roller surrounded by the roller surfaces 2 can be changed, two limiting mechanisms 4 are respectively positioned at two ends of the rotating shaft 1 and used for supporting the roller surfaces 2, wherein each limiting mechanism 4 comprises a sleeve I41, a pull rod 42, a sleeve II 43 and a spring 44, the sleeve I41 is engaged on the rotating shaft 1 and can move along the axial direction of the rotating shaft 1, one end of each pull rod 42 is hinged with the sleeve I41 through a pin shaft, the other end of each pull rod is hinged with the plurality of roller surfaces 2 through a pin shaft, the number of the pull rods 42 is consistent with the number of the roller surfaces 2, and, the sleeve II 43 is arranged on the rotating shaft 1 in a fit manner and can move along the axial direction of the rotating shaft 1, the end part of the sleeve II 43 is provided with a limiting rod 431, the limiting rod 431 penetrates through the sleeve I41, the spring 44 is sleeved on the limiting rod 431, the two ends of the spring 44 are fixedly connected with the sleeve I41 and the sleeve II 43 respectively, the sleeve I41 can actively move along the rotating shaft 1 and the limiting rod 431 under the condition that the sleeve II 43 is locked on the rotating shaft 1, the threaded sleeve 5 is sleeved on the end part of the rotating shaft 1 and is rotationally connected with the sleeve II 43, the end part of the rotating shaft 1 is provided with threads, the threaded sleeve 5 forms thread transmission on the end part of the rotating shaft 1, and the threaded sleeve 5 can drive the sleeve II 43 to move along the axial direction of the rotating;

a harvester comprises the conveying roller.

When the diameter of a roller surrounded by roller surfaces 2 needs to be changed, the sleeve II 43 is driven to axially move along the rotating shaft 1 by rotating the threaded sleeve 5, at the moment, the friction force generated when the sleeve II 43 and the sleeve I41 move along the rotating shaft 1 is not enough to deform the spring 44, so the sleeve II 43 can drive the sleeve I41 to synchronously move, the sleeve I41 pulls the pull rod 42 to move, the pull rod 42 drives the roller surfaces 2 to displace to achieve the effect of changing the diameter, the displacement of the roller surfaces 2 cannot be limited due to the fact that the flexible connecting plate 3 connected with the roller surfaces 2 can deform, the pull rod 42 is respectively connected with the roller surfaces 2, and the roller surfaces 2 can synchronously expand outwards or contract inwards;

install at the supporting seat at the conveying cylinder and carry out the in-process of carrying the material, because the relation material of material size can with contact between conveying cylinder and the supporting seat, and the condition that the size is too big often can take place to block, this moment because the material can exert a reaction force to cylinder face 2, consequently, cylinder face 2 has the trend of inward movement, and then cylinder face 2 can support pull rod 42 inward movement, pull rod 42 will move this moment and transmit to sleeve I41 on, because sleeve I41 is not limited dead in the epaxial position of pivot 1, sleeve I41 can take place the displacement and finally reach the effect of cylinder face 2 inward contraction, and spring 44 can drive cylinder face 2 and resume to original state, and then guaranteed that conveying cylinder can not the too big and blocked condition of material size.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
