[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1-Figure 10A corn harvester conveying device with adjustable structure includes a main body 1, wherein a feed port 11 and a discharge port 12 are respectively provided at the upper and lower ends of the main body 1, and corn ears enter the main body 1 from the feed port 11. The main body 1 is provided with a conveying component 2, a driving component 3, a linkage component 5 and an adjusting component 6. The conveying component 2 is installed in the main body 1, and the lower end and the upper end of the conveying component 2 correspond to the feed port 11 and the discharge port 12 respectively. The conveying component 2 can convey the corn ears at the feed port 11 to the discharge port 12 for discharge. The driving component 3 is installed on the outer side of the upper end of the main body 1 and is connected to the upper end of the conveying component 2. When the conveying component 2 moves, it can drive the driving component 3 to move synchronously. The linkage component 6 is provided on the main body 1. Component 5 includes a linkage plate 51, which is arranged at the top of the main body 1. One end of the linkage plate 51 is connected to the driving component 3. When the driving component 3 moves, it can drive the linkage plate 51 to reciprocate. The adjustment component 6 includes a swing frame 61 and an acceleration roller 63. The swing frame 61 is rotatably arranged at the upper end of the main body 1, corresponding to the discharge port 12, and cooperates with the other end of the linkage plate 51. The corn ears discharged from the discharge port 12 will fall into the swing frame 61. When the linkage plate 51 reciprocates, it can drive the swing frame 61 to swing back and forth. The acceleration roller 63 is arranged in the swing frame 61. When the swing frame 61 swings back and forth, the acceleration roller 63 can rotate to throw the corn ears out of the swing frame 61.

[0032] When the corn harvester is working, the harvested corn ears will enter the conveying component 2 moving in the main body 1 from the feed port 11, and the conveying component 2 will lift the corn ears from the feed port 11 upward to the discharge port 12, and the corn ears will fall into the swing frame 61 from the discharge port 12. When the conveying component 2 is working, the conveying component 2 drives the linkage plate 51 of the linkage component 5 to reciprocate at the upper end of the main body 1 through the driving component 3, thereby driving the swing frame 61 to swing back and forth. In this process, initially, the swing frame 61 and the main body 1 remain parallel and located on the same straight line, and the linkage plate 51 is completely located at the upper end of the main body 1. When the conveying component 2 starts to work, the driving component 3 drives the linkage plate 51 to move toward the outside of the main body 1, and the moving linkage plate 51 drives the swing frame 61 to swing to one side of the main body 1. During the swinging of the swing frame 61, the acceleration roller 63 rotates rapidly in the swing frame 61, and the corn ears are transported to one side of the main body 1. The corn ears 12 that fall into the swing frame 61 will roll onto the acceleration roller 63, and the rotating acceleration roller 63 will throw the corn ears on it along the angle of the swing frame 61, so that the device can adjust the position of the corn ears entering the peeling machine when conveying the corn ears, so that the corn ears can be evenly distributed in the peeling machine in a fan shape. When the driving component 3 drives the linkage plate 51 to move to the outside of the main body 1 to the maximum stroke, as the driving component 3 continues to run, it will push the linkage plate 51 to move to the inside of the main body 1, so that the linkage plate 51 returns to its original position. In the process of the linkage plate 51 returning to its original position, the linkage plate 51 will drive the swing frame 61 to swing back. When the linkage plate 51 returns to its original position, the swing frame 61 remains parallel to the main body 1 again. At this time, the driving component 3 that continues to move drives the linkage plate 51 to move to the outside of the main body 1 again, thereby swinging the swing frame 61 again, and this reciprocating process is completed until the corn harvesting is completed.

[0033] The difference from the above embodiment lies in that one end of the swing frame 61 close to the discharge port 12 is fixedly connected to two rotating sleeves 611, and the two rotating sleeves 611 are respectively located on the upper and lower sides of the swing frame 61, and the outer side of the swing frame 61 is fixedly connected to a secondary connecting seat 612, and a guide platform 613 is fixedly installed on the bottom of the swing frame 61, and the side of the guide platform 613 away from the discharge port 12 is inclined, and an installation groove 614 is also provided at the bottom of the swing frame 61, and the installation groove 614 is located on the side of the guide platform 613 away from the discharge port 12.

[0034] When the corn ears are discharged from the discharge port 12 , the corn ears will fall onto the guide platform 613 , and then the corn ears will roll along the inclined surface of the guide platform 613 toward the mounting groove 614 .

[0035] The difference from the above-mentioned embodiment lies in that a reversing gear 62 is coaxially fixedly connected to a rotating sleeve 611 at the upper end of the swing frame 61, an acceleration roller 63 is rotatably installed in a mounting groove 614, the acceleration roller 63 extends out of the mounting groove 614 to a certain height, and a friction pattern is provided on the outer side of the acceleration roller 63 to increase the friction between the acceleration roller 63 and the corn cob, one end of the acceleration roller 63 close to the driving component 3 extends out of the mounting groove 614, and the protruding end of the acceleration roller 63 is coaxially fixedly connected to the output shaft of the acceleration motor 64, and the acceleration motor 64 is fixedly installed on the outer side of the swing frame 61.

[0036] When the device is working, the linkage plate 51 drives the swing frame 61 to swing by driving the reversing gear 62. When the linkage plate 51 moves toward the outside of the main body 1, the reversing gear 62 is driven to rotate forward, and the rotating reversing gear 62 drives the swing frame 61 to swing toward one side of the main body 1. When the linkage plate 51 moves to the outside of the main body 1 to the maximum stroke, the reversing gear 62 stops rotating forward, so that the swing frame 61 stops swinging toward the outside of the main body 1. At the same time, the linkage plate 51 starts to return and drives the reversing gear 62 to rotate in the reverse direction. The rotating reversing gear 62 drives the swing frame 61 to swing back. When the swing frame 61 swings, the acceleration motor 64 drives the acceleration roller 63 to rotate. The corn ears rolling down from the guide platform 613 will eventually roll onto the rotating acceleration roller 63, and thus be thrown out of the swing frame 61 by the rotating acceleration roller 63. The friction pattern on the acceleration roller 63 increases the friction between the acceleration roller 63 and the corn ears, preventing the corn ears from slipping on the acceleration roller 63 and thus not being thrown out, thereby ensuring the transportation efficiency of the corn ears.

[0037] The difference from the above embodiment is that a limiting groove 511 is provided at one end of the linkage plate 51, and a linkage groove 512 is provided at the other end of the linkage plate 51. A driving rack 52 is fixedly connected to the side of the linkage plate 51 facing the reversing gear 62, and the driving rack 52 is meshed with the reversing gear 62. An upper rack 53 is fixedly connected to one side of the linkage groove 512, and a lower rack 54 is fixedly connected to the other side of the linkage groove 512.

[0038] When the linkage plate 51 reciprocates, the linkage plate 51 drives the reversing gear 62 to rotate by driving the rack 52 .

[0039] The difference from the above-mentioned embodiment is that the linkage assembly 5 also includes a fixed seat 55 and a limiting rod 56, the fixed seat 55 is fixedly installed on the upper side of the swing frame 61, the linkage plate 51 is slidably installed on the fixed seat 55, the lower end of the limiting rod 56 is fixedly connected to the upper side of the swing frame 61, and the upper end of the limiting rod 56 is slidably connected in the limiting groove 511.

[0040] When the linkage plate 51 moves, it will slide on the fixed seat 55. At the same time, the linkage plate 51 also slides in the same direction on the limiting rod 56 through the limiting groove 511. Through the cooperation of the limiting rod 56 and the fixed seat 55, the linkage plate 51 can maintain linear movement without deviation, thereby ensuring the normal operation of the device.

[0041] The difference from the above embodiment is that the driving assembly 3 includes a rotating shaft 31, which is rotatably mounted on the outside of the main body 1, and a driven pulley 32 and a main bevel gear 33 are coaxially fixedly connected to the rotating shaft 31 in sequence, and the main bevel gear 33 is located between the driven pulley 32 and the outside of the main body 1, and the upper end of the main bevel gear 33 extends from the linkage groove 512.

[0042] When the conveying assembly 2 moves, the conveying assembly 2 will drive the rotating shaft 31 to rotate synchronously through the driven pulley 32, thereby driving the main bevel gear 33 to rotate.

[0043] The difference from the above embodiment is that the drive assembly 3 also includes a mounting shaft 34, which is rotatably mounted on the top of the main body 1, and a secondary bevel gear 35 and a sector gear 36 are coaxially fixedly connected to the mounting shaft 34 in sequence, and the sector gear 36 is located between the secondary bevel gear 35 and the top of the main body 1. Initially, one side of the tooth surface of the sector gear 36 is meshed with the lower rack 54, and the secondary bevel gear 35 is meshed with the main bevel gear 33.

[0044] Among them, when the main bevel gear 33 rotates, it will drive the secondary bevel gear 35 meshing with it, so that the secondary bevel gear 35 drives the mounting shaft 34 to rotate, and drives the fan gear 36 thereon to rotate. Initially, the fan gear 36 will drive the lower rack 54 meshing with it, so that the linkage plate 51 moves toward the outside of the main body 1. When the linkage plate 51 moves to the maximum stroke, the gear teeth of the fan gear 36 disengage from the lower rack 54 meshing with it. As the fan gear 36 continues to rotate, the gear teeth of the fan gear 36 will mesh with the upper rack 53, thereby driving the linkage plate 51 to return. When the linkage plate 51 returns to its original position, the fan gear 36 disengages from the upper rack 53 again and meshes with the lower rack 54 again, thereby driving the linkage plate 51 to move toward the outside of the main body 1 again.

[0045] The difference from the above embodiment is that the discharge port 12 of the main body 1 corresponds to the guide platform 613, a mounting seat 13 is fixedly connected to one side of the upper end of the main body 1, a connecting shaft 14 is fixedly connected to the upper and lower sides of the upper end of the main body 1, the connecting shaft 14 is rotatably connected to the rotating sleeve 611, and a main connecting seat 15 is also fixedly connected to the upper end of the main body 1.

[0046] When the device is running, the swing frame 61 swings on the main body 1 through the cooperation between the rotating sleeve 611 and the connecting shaft 14 .

[0047] The difference from the above embodiment is that the conveying assembly 2 includes a conveying roller 21, a conveying belt 22 and a conveying motor 24. The conveying roller 21 is rotatably installed at the upper and lower ends of the main body 1, and the conveying belt 22 cooperates with the conveying roller 21. The conveying roller 21 is used to drive the conveying belt 22 to rotate in the main body 1, and one end of the conveying roller 21 located at the upper end extends to the outside of the main body 1, and a driving pulley 211 is coaxially fixedly connected to the extended end thereof, and the driving pulley 211 is connected to the driven pulley 32 through a belt 4. A plurality of baffles 23 are fixedly connected to the conveying belt 22, and the plurality of baffles 23 are evenly arranged on the conveying belt 22. The conveying motor 24 is fixedly installed on the mounting seat 13, and the conveying motor 24 cooperates with the other end of the conveying roller 21 located at the upper end.

[0048] Among them, when the conveying component 2 is working, the conveying motor 24 will first drive the conveying roller 21 to rotate, thereby driving the conveyor belt 22 thereon to convey the corn ears from the feed port 11 to the discharge port 12. During this process, the baffle 23 on the conveyor belt 22 can prevent the corn ears from slipping off the conveyor belt 22. At the same time, the rotating conveying roller 21 drives the driving pulley 211 to rotate, so that the driving pulley 211 drives the driven pulley 32 to rotate synchronously through the belt 4.

[0049] Embodiment 2: The difference from the above embodiment is that a telescopic rod 7 is arranged between the main body 1 and the swing frame 61, the protruding end of the telescopic rod 7 is rotatably connected to the auxiliary connecting seat 612, and the other end of the telescopic rod 7 is rotatably connected to the main connecting seat 15, and the swing frame 61 drives the telescopic rod 7 to extend and retract when it swings back and forth.

[0050] Among them, the telescopic rod 7 is connected between the swing frame 61 and the main body 1, so that the telescopic rod 7 can provide certain support for the swing frame 61 when the swing frame 61 swings, thereby ensuring the stability of the swing frame 61. When the swing frame 61 swings toward one side of the main body 1, the telescopic rod 7 will rotate synchronously with the swing of the swing frame 61. During this process, the output end of the telescopic rod 7 will be further extended. When the swing frame 61 swings back, the telescopic rod 7 will rotate synchronously with the swing of the swing frame 61. During this process, the extended output end of the telescopic rod 7 will retract to its original length.

[0051] Working principle: When the corn harvester is working, first, the conveying motor 24 drives the conveying roller 21 to rotate, thereby driving the conveyor belt 22 thereon to convey the harvested corn ears from the feed port 11 to the discharge port 12. In this process, the baffle 23 on the conveyor belt 22 can prevent the corn ears from slipping off the conveyor belt 22. At the same time, the rotating conveying roller 21 drives the driving pulley 211 to rotate, so that the driving pulley 211 drives the driven pulley 32 to rotate synchronously through the belt 4, thereby driving the main bevel gear 33 to rotate. When the main bevel gear 33 rotates, it will drive the secondary bevel gear 35 meshing therewith, so that the secondary bevel gear 35 drives the mounting shaft 34 to rotate, and drives the fan gear 36 thereon to rotate. Initially, the fan gear 36 will drive The lower rack 54 meshing with it is driven to make the linkage plate 51 move toward the outside of the main body 1, driving the reversing gear 62 to rotate forwardly, and the rotating reversing gear 62 drives the swing frame 61 to swing toward one side of the main body 1. When the linkage plate 51 moves to the maximum stroke, the gear teeth of the sector gear 36 disengage from the lower rack 54 meshing with it. As the sector gear 36 continues to rotate, the gear teeth of the sector gear 36 will mesh with the upper rack 53, thereby driving the linkage plate 51 to return and drive the reversing gear 62 to rotate in the opposite direction. The rotating reversing gear 62 drives the swing frame 61 to swing back. When the linkage plate 51 returns to its original position, the sector gear 36 disengages from the upper rack 53 again and meshes with the lower rack 54 again, thereby driving the linkage plate 51 to move toward the outside of the main body 1 again.

[0052] When the swing frame 61 swings, the acceleration motor 64 drives the acceleration roller 63 to rotate, and the corn ears rolling down from the guide platform 613 will eventually roll onto the rotating acceleration roller 63. The rotating acceleration roller 63 throws the corn ears on it along the angle of the swing frame 61, so that the device can adjust the position of the corn ears entering the peeling machine when conveying the corn ears, so that the corn ears can be evenly distributed in the peeling machine in a fan shape. At the same time, the friction pattern on the acceleration roller 63 increases the friction between the acceleration roller 63 and the corn ears, preventing the corn ears from slipping on the acceleration roller 63 and thus not being thrown out, thereby ensuring the corn ears are kept in the peeling machine. The efficiency of conveying the ears of corn is improved by repeating this process until the corn harvest is completed. The telescopic rod 7 is connected between the swing frame 61 and the main body 1, so that the telescopic rod 7 can provide certain support for the swing frame 61 when the swing frame 61 swings, thereby ensuring the stability of the swing frame 61. When the swing frame 61 swings toward one side of the main body 1, the telescopic rod 7 will rotate synchronously with the swing of the swing frame 61. During this process, the output end of the telescopic rod 7 will be further extended. When the swing frame 61 swings back, the telescopic rod 7 will rotate synchronously with the swing of the swing frame 61. During this process, the extended output end of the telescopic rod 7 will be retracted to its original length.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
