The inner wall of the fixed ring seat 122 is connected to the second transmission shaft 11. The outer side of the fixed ring seat 122 is fixedly connected to a star-shaped guide wheel 121. The star-shaped guide wheels 121 on adjacent second transmission shafts 11 are arranged in a staggered manner. Figure 2 , Figure 3 As shown, through the multiple star-shaped guide wheels 121 on the second transmission shaft 11, on the one hand, the disordered corn ears can be combed and guided, so that the corn ears entering the peeler can be in the best peeling position; on the other hand, the corn ears can be kept in contact with the peeling iron roller 6 and the peeling rubber roller 7 and continuously transported backwards, thereby improving the peeling rate of corn kernels and bracts.

[0033] The second transmission assembly 13 includes a first sprocket 131 fixed to one end of the second transmission shaft 11. The first sprockets 131 are connected to each other through a transmission chain. The other end of one of the second transmission shafts 11 is fixedly connected to a second sprocket 132. Figure 2 , Figure 3 As shown, the second sprocket 132 is connected to an external power chain to provide power to the first sprocket 131, and then the first sprocket 131 is used to drive multiple star-shaped guide wheels 121 on the outside of the second transmission shaft 11 to rotate together to perform the combing, guiding and pressing of corn ears.

[0035] The third transmission assembly 17 includes an L-shaped rod 171 fixed to one side of the material collecting bin 14. By setting the L-shaped rod 171, one end of the third transmission shaft 15 can be supported, so that the discharge assembly 16 can rotate more stably and smoothly; one end of the third transmission shaft 15 is rotatably connected to the L-shaped rod 171, and the other end of the third transmission shaft 15 passes through the outside of the material collecting bin 14 and is installed with a side half shaft assembly 172, such as Figure 2 , Figure 3 As shown, the external power drive device provides power to the third transmission shaft 15 through the side half-shaft assembly 172. The third transmission shaft 15 can drive the discharge assembly 16 to rotate to discharge corn kernels and husks into the separation device, so as to facilitate the collection of corn kernels.

[0036] The limiting assembly 19 includes a limiting stopper 191 disposed on the outside of the rubber sleeve 18, and a round boss 192 is provided on one side of the limiting stopper 191. The round boss 192 is connected to the outside of the peeling rubber roller 7 through a key, such as Figure 6 , Figure 7 As shown, the limit stop plate 191 can be used to limit the axial displacement of the rubber sleeve 18, thereby preventing the rubber sleeve 18 from detaching from both ends of the peeling rubber roller 7, thereby improving the installation stability.

[0037] The outer side of the peeling rubber roller 7 is symmetrically provided with a plurality of docking ridges 21, and the inner wall of the rubber sleeve 18 is provided with docking grooves 22 corresponding to the docking ridges 21, and the docking ridges 21 are located inside the docking grooves 22, such as 6, Figure 7 As shown, by setting the docking ridges 21 and the docking grooves 22, the circumferential displacement of the rubber sleeve 18 can be limited. The limit assembly 19 can effectively prevent the rubber sleeve 18 from being displaced due to excessive friction during the peeling process, thereby further improving the installation stability. At the same time, the docking ridges 21 can act as reinforcing ribs to improve the overall flexural strength of the peeling rubber roller 7, thereby better resisting the force from the pressure-feeding assembly 12.

[0038] The quick-release assembly 20 includes a mounting shell 201 arranged on the outside of the peeling rubber roller 7. There are two mounting shells 201. Each mounting shell 201 has a connecting portion 202 on both sides. A fastening bolt 203 is arranged inside the upper connecting portion 202. An annular slider 205 is fixedly connected to the outer side of the fastening bolt 203. An annular slide groove 206 corresponding to the annular slider 205 is opened on the inner wall of the upper connecting portion 202. The annular slider 205 is located inside the annular slide groove 206. An internal threaded hole 204 corresponding to the fastening bolt 203 is opened on the top of the lower connecting portion 202. The bottom end of the fastening bolt 203 is located inside the internal threaded hole 204. An anti-slip block 207 is fixedly connected to the top of the fastening bolt 203. An anti-slip groove 208 corresponding to the anti-slip block 207 is opened on the inner wall of the upper connecting portion 202. The anti-slip block 207 is located inside the anti-slip groove 208. Figure 7 , Figure 8As shown, after the rubber sleeve 18 is installed on the peeling rubber roller 7, the two mounting shells 201 can press and position the rubber sleeve 18 tightly from both ends to fix it on the outside of the peeling rubber roller 7. When the rubber sleeve 18 needs to be replaced, the fastening bolt 203 is screwed out of the internal threaded hole 204 using an Allen wrench. At this time, the two mounting shells 201 can be separated, and the limit assembly 19 can also be removed from both ends of the peeling rubber roller 7. This simplifies the maintenance and replacement process of the rubber sleeve 18 and reduces the difficulty of maintenance and replacement of the rubber sleeve 18. In addition, by arranging the anti-slip block 207 and the anti-slip groove 208, the fastening bolt 203 can be prevented from being separated from the connecting part 202 without hindering the rotation of the fastening bolt 203, thereby eliminating the trouble of losing the fastening bolt 203 and improving practicality.

[0039] Working principle: First, the staff installs the present invention below the discharge port of the corn harvester elevator, and then combs and guides the messy corn ears through the pressure-feeding component 12, so that the corn ears keep in contact with the peeling iron roller 6 and the peeling rubber roller 7 and continue to be transported backward, and then cooperates with the first transmission component 8 to drive the peeling rubber roller 7 and the peeling rubber roller 7 to rotate in opposite directions, and the outer bracts of the corn ears that fall in between are forcibly pulled down, and then the corn kernels are peeled off, thus realizing the peeling operation of the corn ears, and then the corn kernels and bracts can be discharged into the external separation device through the discharge component 16, which is convenient for collecting the corn kernels. When the peeling rubber roller 7 needs to be disassembled and replaced after working for a long time, the quick-release component 20 and the limit component 19 are used to facilitate the inspection and replacement of the rubber cover 18 on the outer side of the peeling rubber roller 7, thereby simplifying the inspection and replacement process of the rubber cover 18, reducing the difficulty of inspection and replacement of the rubber cover 18, and reducing the labor burden of the staff.
