Description
Technical Field
[0001] The utility model relates to corn processing equipment, in particular to a corn husk folding device. Background Art
[0002] Corn husking machine, also known as husk folding machine, is a kind of equipment that can automatically separate corn husks from ears. It is equipped with relatively rotating peeling rollers. Since the peeling rollers are equipped with roller sleeves with spiral strips and rubber nails, the peeling rollers can evenly distribute the ears that have entered the machine between the relatively rotating rollers, and smoothly move forward while the ears rotate themselves. During the process, the husks are torn apart by special peeling claws, and the rotating shaft instantly presses the husks and pulls them down, thus completing the purpose of peeling.
[0003] Since the roller sleeve on the peeling roller is usually a wearable part, it will wear out after a period of use. After wear, it must be removed from the roller shaft for replacement. However, in the technology of corn peeling machines, a cylindrical roller sleeve is usually set on the roller shaft. When the roller sleeve is disassembled, the roller shaft needs to be disassembled together so that the roller sleeve can be removed along the axis of the roller shaft. The overall disassembly work is large and very laborious, which is inconvenient.

[0023] Example
[0024] Reference Figure 1-6 , a corn husking device, comprising an active peeling roller 20 and a passive peeling roller 30 symmetrically arranged on a frame 10, the active peeling roller 20 and the passive peeling roller 30 are parallel to each other and one end is driven by gear meshing, the shaft ends of the active peeling roller 20 and the passive peeling roller 30 are connected to the frame 10 through a bearing seat, the driving mechanism drives the active peeling roller 20 to rotate, and the roller body of the active peeling roller 20 is sequentially sleeved with a plurality of cylindrical peeling roller sleeves 23 along the roller core direction, characterized in that the active peeling roller 20 comprises a core shaft 21, both ends of the core shaft 21 are connected to the bearing seats on the frame 10, the peeling roller sleeve 23 is sleeved on the shaft body of the core shaft 21, wherein the peeling roller sleeve 23 is composed of a first and a second half sleeve 23A, 23B which are symmetrically arranged on the circumference of the core shaft 21 and have a semicircular cross-section as a whole, the first and the second half sleeves 23A, 23B are separated from each other and connected to the core shaft 21 by bolts.
[0025] The corn falls between the active peeling roller 20 and the passive peeling roller 30, which can rotate relative to each other through the meshing of gears. The specific arrangement of the spiral strips and rubber nails on the active peeling roller 20 and the passive peeling roller 30 is prior art and will not be elaborated here. It should be noted that the peeling roller sleeve 23 in this application is multi-stage.
[0026] In the above scheme, the peeling roller sleeve 23 is composed of the first and second half sleeves 23A and 23B which are symmetrically arranged on the circumferential surface of the core shaft 21 and have a semicircular cross-section as a whole, and the first and second half sleeves 23A and 23B are separated from each other. When disassembling the peeling roller sleeve 23, the bolts used to fix the peeling roller sleeve 23 to the core shaft 21 can be removed without disassembling the core shaft 21. The peeling roller sleeve 23 can be directly separated and removed from the core shaft 21 at the machine position, and a new peeling roller sleeve 23 can be installed in the same way at the corresponding position on the core shaft 21. The peeling roller sleeve 23 is quicker to disassemble and assemble. According to the usage of the peeling roller sleeves 23 in different sections, the specified peeling roller sleeves 23 can be selectively disassembled, and the other peeling roller sleeves 23 remain stationary, thereby reducing unnecessary disassembly work.
[0027] As a preferred solution, the cross section of the shaft of the mandrel 21 is square, and grooves 24 matching the shape of the mandrel 21 are provided on the opposite sides of the first and second half sleeves 23A and 23B, and the mandrel 21 is inserted into the core cavity formed by the grooves 24. Through the matching of the shape of the mandrel 21 and the grooves 24, when installing the first and second half sleeves 23A and 23B, the first and second half sleeves 23A and 23B can be limited, so that they can be quickly and accurately positioned at the corresponding installation positions on the mandrel 21, and the first and second half sleeves 23A and 23B will not produce rotational deviation with the mandrel 21, so as to facilitate alignment of the hole positions for fixing.
[0028] Furthermore, connectors 22 are coaxially arranged at both ends of the mandrel 21, and the connectors 22 are rotationally matched with the first and second bearing seats 40A and 40B arranged oppositely on the frame 10. The mandrel 21 and the first and second bearing seats 40A and 40B are transitionally connected through the connectors 22.
[0029] As a preferred solution, in order to facilitate the disassembly of the active peeling roller 20 as a whole, the axial holes of the first and second bearing seats 40A and 40B are connected with connecting shafts 41 coaxial with the core shaft 21, and the connecting shaft 41 can rotate in the axial holes of the corresponding bearing seats. The connectors 22 at both ends of the core shaft 21 are detachably connected to the connecting shafts 41 on the first and second bearing seats 40A and 40B, respectively. When the peeling roller sleeves 23 on the core shaft 21 need to be replaced or the active peeling roller 20 as a whole needs to be replaced, the connector 22 can be separated from the first and second bearing seats 40A and 40B to reinstall the new active peeling roller 20 on the first and second bearing seats 40A and 40B, without the need to disassemble the first and second bearing seats 40A and 40B, thereby reducing the amount of disassembly and assembly work, and making it more convenient to replace the active peeling roller 20.
[0030] Furthermore, the opposite ends of the connecting shaft 41 are provided with fixing grooves 42 whose groove length direction is perpendicular to the axis core direction of the connecting shaft 41, and the connecting heads 22 at both ends of the core shaft 21 are inserted and matched with the corresponding fixing grooves 42. A plug 43 is provided on the circumferential surface of the connecting shaft 41 along an edge perpendicular to the axis core and the groove length direction of the fixing groove 42. The end of the plug 43 adjacent to the connecting head 22 is inserted into the corresponding fixing hole 221 on the connecting head 22, and a spring 44 is connected between the external end of the plug 43 and the connecting shaft 41 to form a radial floating fit.
[0031] When the active peeling roller 20 needs to be removed from the frame 10, the plug 43 can be pulled out so that the end of the plug 43 near the connector 22 can be disengaged from the corresponding fixing hole 221 on the connector 22, canceling the fixing effect between the connector 22 and the connecting shaft 41, and the connector 22 can be removed from the fixing groove 42 on the connecting shaft 41, so that the mandrel 21 can be quickly separated from the first and second bearing seats 40A and 40B. Conversely, the connector 22 on the new active peeling roller 20 is inserted into the fixing groove 42 on the connecting shaft 41 and the plug 43 is pushed into the corresponding fixing hole 221, so that the active peeling roller 20 can be quickly fixed as a whole.
[0032] As a preferred solution, the cross-sections of the connector 22 and the fixing groove 42 are both square, which can provide positioning guidance for the insertion of the connector 22 and avoid the connector 22 and the core shaft 21 being coaxially deflected through the connecting shaft 41, resulting in difficulty in positioning.
[0033] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
