[0034] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0035] The feeding roller and the agricultural machine according to the present invention will be described below with reference to the accompanying drawings.

[0036] like Figure 1As shown, in this embodiment, a feeding roller is proposed, which includes a roller body 1, a locking member 2 and a rotary drive member 3. The roller body 1 has a connecting shaft 13 at both ends along the length direction, and the outer peripheral wall of the connecting shaft 13 is coaxially sleeved with a rotating shaft connector 9. The locking member 2 is coaxially sleeved on the outer peripheral wall of the connecting shaft 13, and the locking member 2 is arranged on the side of the rotating shaft connector 9 away from the roller body 1. The rotating shaft connector 9 and the locking member 2 cooperate to axially limit the roller body 1. The rotary drive member 3 is drive-connected to the connecting shaft 13, and the rotary drive member 3 is used to drive the roller body 1 to rotate around its own axis. It should be noted that the rotating shaft connector 9 in this embodiment is a bearing, the locking member 2 adopts a common locking nut, and the rotary drive member 3 adopts a motor.

[0037] The rotary drive member 3 is drivably connected to the connecting shaft 13 and is used to drive the roller body 1 to rotate about its own axis. The roller body 1 is provided with a connecting shaft 13 at both ends along its length. The outer peripheral wall of the connecting shaft 13 is coaxially sleeved with a rotating shaft connector 9 and a locking member 2. When the feed roller is in operation, the rotary drive member 3 drives the connecting shaft 13 to rotate about its own axis, driving the roller body 1 to rotate along with it. At this time, the locking member 2, arranged on the side of the rotating shaft connector 9 facing away from the roller body 1, acts as a limiter for the roller body 1, preventing the roller body 1 from moving axially with the connecting shaft 13 during operation. This avoids the problem of severe wear of the mating parts between the rotary drive member 3 and the connecting shaft 13 due to axial deviation of the roller body 1 during operation.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, the roller body 1 includes a roller body 11 and two connecting seats 12 spaced apart on both sides of the roller body 11 along the length direction of the roller body 11. The roller body 11 and the connecting seats 12 are detachably connected. A connecting shaft 13 is connected to the side of the connecting seat 12 facing away from the roller body 11. The connecting shaft 13 is formed with a mounting groove for plugging and mating with the rotary drive member 3. In this embodiment, the connecting shaft 13 and the connecting seat 12 are integrally formed, having good structural strength and capable of withstanding strong axial rotational driving forces, thereby ensuring a stable connection between the connecting shaft 13, the connecting seat 12 and the roller body 11.

[0039] like Figure 1 As shown, in this embodiment, the feed roller further includes a mounting seat 4, one end of which is connected to the outer peripheral wall of the rotating shaft connector 9, and the other end is detachably connected to the external frame 100 by bolts, and a limiting protrusion 43 is formed on the side of the mounting seat 4 facing the connecting shaft 13. Figure 2Taking an example to illustrate, by moving the locking piece 2 on the connecting shaft 13 to the left and locking it after the locking piece 2 presses the rotating shaft connecting piece 9 onto the limiting protrusion 43, it is possible to apply pressure to the external frame 100 through the mounting seat 4, thereby tightening the external frame 100, strengthening the rigidity of the external frame 100, and effectively improving the reliability of the connection between the external frame 100 and the roller body 1, so that the feeding roller has good operating performance.

[0040] Furthermore, the mounting seat 4 includes a transverse connector 41 and a vertical connector 42 connected to one end of the transverse connector 41. The transverse connector 41 is arranged on the side of the vertical connector 42 facing the shaft connector 9. A limiting protrusion 43 is formed on the transverse connector 41. The limiting protrusion 43 is located between the shaft connector 9 and the roller body 11, and can limit the shaft connector 9 to prevent the shaft connector 9 from moving in the axial direction. The vertical connector 42 is detachably connected to the external frame 100. The transverse connector 41 and the vertical connector 42 are integrally formed and arranged in an L-shape. The overall structural strength is high and the support stability is good. Among them, when the transverse connector 41 is a circular ring, the inner side wall of the transverse connector 41 matches the outer peripheral wall size of the shaft connector 9, which can effectively limit the shaft connector 9 in the radial direction to prevent the shaft connector 9 from radially offsetting. When the transverse connecting member 41 is a plate-shaped structure, it is only necessary to ensure that the distance between the two transverse connecting members 41 on the opposite sides of the rotating shaft connecting member 9 is adapted to the outer peripheral wall of the rotating shaft connecting member 9 .

[0041] In this embodiment, the feed roller further includes a flange 5 mounted on the rotary drive member 3. One end of the flange 5 is detachably connected to the side of the mounting base 4 facing away from the roller body 11 by bolts. The other end of the flange 5 forms an opening into which the rotary drive member 3 extends. The flange 5 has a space for accommodating the locking member 2. A certain distance is maintained between the flange 5 and the locking member 2 to prevent wear caused by contact between the locking member 2 and the flange 5 during the rotation of the connecting shaft 13.

[0042] In the first embodiment, there are two rotary drive members 3, which are respectively connected to two connecting shafts 13. In other words, one rotary drive member 3 is connected to each of the two connecting shafts 13, and each of the two connecting shafts 13 is provided with a locking member 2 for limiting the axial deviation of the roller body 1. A limiting protrusion 43 is formed on the side of the transverse connecting member 41 facing the connecting shaft 13, and a limiting portion 7 is formed on the side of the flange member 5 facing the rotating shaft connecting member 9. The outer peripheral wall of the rotating shaft connecting member 9 is embedded between the limiting protrusion 43 and the limiting portion 7. The cooperation between the limiting protrusion 43 and the limiting portion 7 can further provide a better axial limiting effect, so that the position of the rotating shaft connecting member 9 is fixed and the rotating shaft connecting member 9 will not deviate axially with the rotation of the connecting shaft 13.

[0043] like Figure 1 and Figure 2 As shown, in the second embodiment, there is one rotary drive member 3 connected to one of the connecting shafts 13. The feed roller also includes a dust cover 6, the free end of which is detachably connected to the transverse connector 41. The dust cover 6 and the mounting seat 4 cooperate to form a sealed space surrounding the second end of the connecting shaft 13, ensuring that the rotating shaft connector 9 is always in a sealed and lubricated environment, allowing smooth cooperation between the rotating shaft connector 9 and the connecting shaft 13. A limiting protrusion 43 is formed on the side of the transverse connector 41 facing the connecting shaft 13. A limiting portion 7 is formed on the side of the flange 5 and the dust cover 6 facing the rotating shaft connector 9. The outer peripheral wall of the rotating shaft connector 9 is embedded between the limiting protrusion 43 and the limiting portion 7. As in the first embodiment, the cooperation between the limiting protrusion 43 and the limiting portion 7 can effectively prevent the rotating shaft connector 9 from axially deviating as the connecting shaft 13 rotates.

[0044] like Figure 1 and Figure 2 As shown, in this embodiment, the feed roller further includes a spline transition sleeve 8 that is sleeved on the driving end of the rotary drive member 3. The outer peripheral wall of the spline transition sleeve 8 is formed with external splines that mesh with the inner sidewall of the mounting groove, and the inner peripheral wall of the spline transition sleeve 8 is formed with internal splines that mesh with the outer peripheral wall of the rotary drive member 3. The driving end of the rotary drive member 3 is formed with spline teeth, and the inner sidewall of the mounting groove is also formed with spline teeth. During assembly, the spline transition sleeve 8 is first engaged and assembled with the driving end of the rotary drive member 3, and the outer splines of the spline transition sleeve 8 are engaged and assembled with the inner sidewall of the mounting groove.

[0045] like Figure 2 As shown, in this embodiment, the rotary drive member 3 includes a mounting portion 31 and a driving portion 32. The driving portion 32 is inserted into the mounting groove. A quick-connect mounting plate 33 is provided on the outer peripheral wall of one end of the mounting portion 31 close to the driving portion 32. The flange member 5 can be detachably mounted on the quick-connect mounting plate 33.

[0046] This embodiment also provides an agricultural machine comprising the feed roller described above. Since the agricultural machine utilizes all embodiments of the feed roller, it also possesses all the beneficial effects of the feed roller, which will not be described in detail here. It should be noted that the agricultural machine can be a variety of machines, such as a sugarcane harvester or a corn harvester. This embodiment uses the feed roller in a sugarcane harvester as an example to effectively address the technical issues in the prior art where the feed roller lacks axial restraint, resulting in severe wear of the mating components between the rotary drive member 3 and the connecting shaft 13 and high production costs.
