Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in combination with the following embodiments. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: with reference to fig. 1-4, a roller special for agricultural machinery comprises a main shaft 1, flanges 2 are arranged at two ends of the main shaft 1, a plurality of round steel 3 are arranged between the two flanges 2, a first center hole 24 is arranged in the middle of each flange 2, the main shaft 1 is located in the first center hole 24, a plurality of first grooves 21 are arranged on the outer circumference of each flange 2, the end portions of the round steel 3 are located in the first grooves 21, and the round steel 3 protrudes out of the outer circumference of each flange 2. The flange 2 is welded on the main shaft 1, and the round steel 3 is welded on the flange 2.

The cross section of the first groove 21 is arc-shaped, the radius of the arc is not smaller than the diameter of the round steel 3, and when the arc is actually manufactured, the radius of the arc is larger than the diameter of the round steel 3 by 0.05-0.1 mm, so that the end part of the round steel 3 can be conveniently placed into the first groove 21, and the jumping degree of the round steel 3 can be well guaranteed to be qualified when the welding is completed and the main shaft 1 rotates.

The both sides of first recess 21 are provided with first chamfer 22, and form the groove between with round steel 3, can increase the firm degree of welding round steel 3.

The flange 2 is manufactured by a deep drawing process, so that the thickness of the flange 2 is relatively thick, the contact and welding length and area between the first groove 21 and the round steel 3 are increased, and the welding firmness is improved. Due to the adoption of the deep drawing process, the flange 2 has the characteristic of thin wall, and a concave platform 23 is formed on one side of the flange, so that the material is saved.

The main shaft 1 comprises a shaft middle section 11, shaft end parts 12 are arranged on two sides of the shaft middle section 11, and the diameter of the shaft middle section 11 is larger than that of the shaft end parts 12, so that a shaft shoulder is formed at the joint of the shaft middle section and the shaft end parts, and the installation and the positioning are convenient.

The spindle 1 is further provided with a supporting piece 4, a second center hole 43 is formed in the middle of the supporting piece 4, the spindle 1 is located in the second center hole 43, and the outer side of the supporting piece 4 is in contact with the round steel 3. The support sheet 4 is welded on the main shaft 1, and the round steel 3 is welded on the support sheet 4.

The supporting sheet 4 is provided with a plurality of second grooves 41 on the outer circumference, the two sides of the second grooves 41 are provided with second chamfers 42, the cross section of each second groove 41 is arc-shaped, the radius of each arc is not less than the diameter of each round steel 3, and each round steel 3 is positioned in each second groove 41.

When in actual use, this roller can be used for the harvester, the both ends that are located the conveyer belt are used for the transmission conveyer belt, when the grain granule falls into between roller and the conveyer belt, can get into the gap between the round steel 3, thereby can not cause wearing and tearing to the conveyer belt, the service life of conveyer belt has been improved, simultaneously the grain granule also can not damage, because round steel 3 protrusion in the outer circumference of flange 2, consequently there is the clearance between the outer circumference of conveyer belt and flange 2, at roller pivoted in-process, grain granule and other debris can throw away the external world from this clearance very fast, thereby can not accumulate in the roller.
