Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a peeling mechanism and peeling roller for an agricultural harvester. Background Technology

[0002] In the corn processing, the peeling of corn husks is a time-consuming and labor-intensive process. In mountainous areas or regions where large corn harvesters are difficult to operate, corn husk peeling is mainly done manually or with corn peeling machines. Existing corn peeling machines have a push shaft and a peeling shaft arranged in parallel. The peeling shaft is equipped with multiple rubber rings fitted onto the shaft rollers, and these rubber rings are fitted with peeling rubber teeth. The peeling rubber teeth work together to peel off the corn husks.

[0003] For example, the corn peeling machine described in patent document number CN204443194U includes a shell and a peeling device. The peeling device includes a push shaft and a peeling shaft. The peeling shaft includes a roller, on which multiple rubber rings are fitted. The outer rings of the rubber rings are provided with peeling rubber teeth. The roller has elongated protrusions along its axial direction. Each rubber ring has a groove that matches the elongated protrusion. Extrusion discs for pressing the rubber rings are fitted at both ends of the roller. The outer surface of the push shaft is provided with peeling toothed strips and peeling cylindrical strips. The elongated protrusions allow the rubber rings to rotate with the roller even when subjected to significant resistance, preventing the rubber rings from rotating relative to the roller, thus improving the stability of the corn peeling machine and increasing labor efficiency.

[0004] However, the above mechanism has the following drawbacks: First, the propulsion shaft is spirally threaded, and the peeling shaft is a raised rubber ring that increases friction. This results in the corn husks taking a long time to be clamped between the two shafts for peeling, leading to low efficiency. Second, the propulsion shaft and peeling shaft need to rotate in opposite directions to peel. If gears are installed between them, it will affect the clearance between the propulsion shaft and peeling shaft, affecting peeling. Therefore, this mechanism requires two sets of propulsion shafts and peeling shafts, with meshing gears between the propulsion shafts to peel, which increases manufacturing costs. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a peeling mechanism and peeling roller for an agricultural harvester, characterized in that: the peeling mechanism and peeling roller include a right-propelling peeling roller 2 and a left-propelling peeling roller 7 that mesh with each other; the right-propelling peeling roller 2 and the left-propelling peeling roller 7 are provided with peeling spiral teeth 11 of the same size and meshing with each other, but the spiral directions of the peeling spiral teeth 11 on the right-propelling peeling roller 2 and the left-propelling peeling roller 7 are opposite; the front ends of the right-propelling peeling roller 2 and the left-propelling peeling roller 7 are both supported on the frame by a sliding sleeve 1, and the tail ends are supported on the frame by a bearing seat 6; the tail ends of the right-propelling peeling roller 2 and the left-propelling peeling roller 7 are respectively provided with a tail support long shaft 2 and a tail support short shaft 5, and the tail support long shaft 2 on the right-propelling peeling roller 2 is provided with a drive wheel 4 connected to a power source.

[0006] Furthermore, the front ends of the right push peeling roller 2 and the left push peeling roller 7 are both provided with a front support shaft 8 and a cone 9, and the cone 9 is provided with a hinge 10, but the spiral directions of the hinge 10 on the right push peeling roller 2 and the left push peeling roller 7 are opposite.

[0007] Furthermore, the bearing housing 6 is a double bearing housing, and the distance between the two bearings is equal to the center distance between the two peeling spiral teeth 11.

[0008] Furthermore, the sliding sleeve 1 has uniformly distributed oil rings 14 inside, and an oil storage groove 12 on its upper surface, with a corresponding oil inlet 13 between the oil storage groove 12 and the oil rings 14.

[0009] This invention has the following advantages: First, both the push shaft and the peeling shaft are made of rubber spiral teeth, which allows the corn husks to be quickly clamped and peeled by the spiral teeth of the two shafts, thus improving peeling efficiency; Second, both the push shaft and the peeling shaft are spiral teeth, which mesh with each other to peel, avoiding the need for two sets of push shafts and peeling shafts, reducing the size of the peeling mechanism and saving manufacturing costs; Third, the front end of the peeling mechanism is equipped with a guide mechanism to feed the corn into the peeling spiral teeth at the rear.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 This utility model provides a technical solution: an agricultural harvester peeling mechanism and peeling roller includes a right push peeling roller 2 and a left push peeling roller 7 that mesh with each other. The right push peeling roller 2 and the left push peeling roller 7 are provided with peeling spiral teeth 11 of the same size that mesh with each other, but the spiral directions of the peeling spiral teeth 11 on the right push peeling roller 2 and the left push peeling roller 7 are opposite. This allows the right push peeling roller 2 and the left push peeling roller 7 to rotate in opposite directions, and the two peeling spiral teeth 11 can peel the corn husks.

[0016] Both the front ends of the right push peeling roller 2 and the left push peeling roller 7 are provided with a front support shaft 8 and a cone 9. The tail ends of the right push peeling roller 2 and the left push peeling roller 7 are respectively provided with a tail support long shaft 2 and a tail support short shaft 5. Both cones 9 are provided with a hinge 10, but the spiral directions of the hinge 10 on the right push peeling roller 2 and the left push peeling roller 7 are opposite. This allows the corn to be fed into the peeling mechanism at the rear for peeling. The front support shaft 8 of the right push peeling roller 2 and the left push peeling roller 7 is supported on the frame by a sliding sleeve 1, and the tail end is supported on the frame by a bearing seat 6. The tail support long shaft 2 on the right push peeling roller 2 is provided with a drive wheel 4 connected to the power source. The drive wheel 4 drives the right push peeling roller 2 to rotate, and the meshing peeling spiral teeth 11 drive the left push peeling roller 7 to move in the opposite direction.

[0017] Meanwhile, the bearing housing 6 is a double bearing housing, and the distance between the two bearings is equal to the center distance between the two peeling spiral teeth 11, ensuring the meshing accuracy.

[0018] To improve lubrication and rotation efficiency, the sleeve 1 is provided with a uniformly distributed oil ring 14 inside, and an oil storage groove 12 is provided on the upper surface. A corresponding oil inlet 13 is provided between the oil storage groove 12 and the oil ring 14 to continuously provide good lubrication to the right push peeling roller 2 and the left push peeling roller 7.

[0019] To improve leaf stripping efficiency, the peeling spiral tooth 11 can be replaced with a rubber sleeve.
