[0020] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of the application is usually placed, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] As shown in Figures 1-6 A new drive roller of a header, comprising a drive roller body 1 for driving the operation of a sweeping assembly, crops passing through two adjacent drive roller bodies 1 reach a picking assembly, a plurality of drive roller bodies 1 are vertically and parallel arranged inside a header body 2, the drive roller body 1 comprises a feeding roller 3 and a transmission roller 4, the feeding roller 3 is located on the upper side of the transmission roller 4, the circumferential surface of the feeding roller 3 is provided with a helical first feeding protrusion 5 and a plurality of vertical second feeding protrusions 6, the helical directions of the first feeding protrusions 5 of two adjacent feeding rollers 3 are opposite.

[0022] As shown in Figure 3 The circumferential direction of the feeding roller 3 is provided with a helical auxiliary protrusion 7, the pitch of the auxiliary protrusion 7 is equal to the pitch of the first feeding protrusion 5, and the auxiliary protrusion 7 and the first feeding protrusion 5 are arranged alternately.

[0023] The auxiliary protrusion 7 and the first feeding protrusion 5 are uniformly and equidistantly arranged, and the pitch of the first feeding protrusion 5 should be greater than 2 times the thickness of the auxiliary protrusion 7.

[0024] As shown in Figure 3 The side surface of the first feeding protrusion 5 away from the feeding roller 3 is an outwardly protruding circular arc surface, and the width of the first feeding protrusion 5 is not less than the width of the second feeding protrusion 6.

[0025] As shown in Figure 3 The first feeding protrusion 5 and the second feeding protrusion 6 form a helical connecting groove 8, the auxiliary protrusion 7 forms an auxiliary block in the connecting groove 8, the thickness of the side surface of the auxiliary block away from the drive roller body 1 gradually decreases from top to bottom, and the radial width of the auxiliary block gradually increases from top to bottom.

[0026] Since the width of the auxiliary protrusion 7 is less than the width of the second feeding protrusion 6, the second feeding protrusion 6 will cut off the auxiliary protrusion 7 to form a plurality of auxiliary blocks, and the helical direction of the auxiliary protrusion 7 is the same as that of the first feeding protrusion 5.

[0027] AsFigure 3 As shown, the circumferential surface of the drive roller 4 is provided with vertical third feeding protrusions 9, the lower part of the second feeding protrusions 6 and the third feeding protrusions 9 are both smooth sawtooth, and the number of the second feeding protrusions 6 is less than that of the third feeding protrusions 9.

[0028] In specific use, a plurality of drive roller bodies 1 are vertically arranged in parallel inside the cutter body 2, and the drive roller body 1 is used to drive the raking assembly to operate.

[0029] The straw is driven by the raking assembly to enter between adjacent drive roller bodies 1;

[0030] Through the action of the first feeding protrusions 5, the second feeding protrusions 6 and the auxiliary protrusions 7, the straw is continuously driven to walk backward;

[0031] Since the first feeding protrusions 5 of adjacent drive roller bodies 1 are in opposite spiral directions, a spiral feeding channel is formed between the adjacent drive roller bodies 1 during rotation, which drives the straw and the corn cob to move backward and upward, avoiding the corn cob from falling between the drive roller bodies 1;

[0032] During the movement of the corn cob driven by the first feeding protrusions 5 and the second feeding protrusions 6, the auxiliary protrusions 7 are used to assist in clamping the corn cob, the width of the auxiliary protrusions 7 is less than that of the first feeding protrusions 5 and the second feeding protrusions 6, which can reduce the extrusion of the corn cob;

[0033] And the outer part of the first feeding protrusions 5 and the second feeding protrusions 6 is a circular arc surface, and the outer part of the auxiliary protrusions 7 is a smooth transition circular arc surface, which can reduce the extrusion pressure of the corn cob, reduce the damage to the corn cob, avoid the corn kernel from falling off, and reduce the loss.
