Description

Technical Field

[0001] The utility model relates to the field of crop harvesting, in particular to a corn harvester auxiliary device for harvesting fallen corns. Background Art

[0002] Corn harvester is an agricultural machine used to improve the efficiency of corn harvesting. It can realize a series of operations such as crop cutting, ear picking, cleaning and bagging. With the advancement of agricultural modernization, this kind of machinery plays an important role in reducing labor intensity and improving production efficiency. Although corn harvesters perform well in peeling and removing dead branches and leaves, they are unable to handle broken corn kernels. These corn kernel fragments that cannot be effectively removed undoubtedly affect the overall quality of the harvested corn. Therefore, in order to ensure the quality, it is often necessary to invest additional manpower and material resources for manual screening, which undoubtedly increases production costs and reduces production efficiency. For this reason, we propose a corn harvester auxiliary device for harvesting fallen corn. Utility Model Content

[0026] A corn kernel screening assembly, which is installed between the inner walls of both sides of the corn kernel collecting tank 4 and is used to separate the debris in the corn kernels;

[0027] The shaking assembly is installed between the inner walls on both sides of the corn kernel collecting tank 4 and is used to shake the corn kernel screening assembly.

[0028] A hollow groove 7 is provided on the side of the baffle 6 near the top, and passes through both sides of the baffle 6. An inclined flow plate 8 is fixedly provided on the bottom inner wall of the hollow groove 7. When in use, the fallen corn is first harvested by the corn harvesting auxiliary device 3, and then the corn kernels on the corn are conveyed to the flow plate 8 through the conveyor belt 2.

[0029] The corn kernel screening assembly includes a collecting iron box 9, a rocking arm 10, a sealing plate 11, a magnetic plate 12 and a cylindrical block 13. The collecting iron box 9 is rotatably connected between the inner walls of both sides of the corn kernel collecting trough 4. Both ends of the collecting iron box 9 are fixedly connected with rocking arms 10. The collecting iron box 9 is rotatably connected to the inner walls of both sides of the corn kernel collecting trough 4 through two groups of rocking arms 10. One side of the collecting iron box 9 is slidably connected with a sealing plate 11 near the top position. One side of the sealing plate 11 extends into the collecting iron box 9 and four groups of vertical cylindrical blocks 13 are fixedly arranged at the corresponding top positions. The flow plate 8 is arranged in an inclined shape to allow the corn kernels to slide into the collecting iron box 9 through the empty slots 7 on the baffle 6. When the collecting iron box 9 is full of corn kernels, the magnetic plate 12 is pushed, so that the magnetic plate 12 drives the sealing plate 11 to slide on the collecting iron box 9 until one side of the magnetic plate 12 is bonded to the side of the collecting iron box 9 due to magnetic force.

[0030] One side of the flow plate 8 extends to a position below the top of the conveyor belt 2, and the other side of the flow plate 8 extends to just above the collecting iron box 9. The cylindrical block 13 on the sealing plate 11 prevents the sealing plate 11 from sliding out of the collecting iron box 9 during the operation of the corn harvester 1.

[0031] Two groups of mutually symmetrical hinge seats 15 are fixedly arranged at the bottom of the collecting iron box 9, and multiple groups of corn holes 14 smaller than the diameter of corn kernels are opened on the sides of the bottom of the collecting iron box 9 corresponding to the two groups of hinge seats 15. The corn kernel debris in the collecting iron box 9 is screened by the multiple groups of corn holes 14 and falls into the corn kernel collecting trough 4 for collection.

[0032] The shaking assembly includes a rotating rod 16, a disc 17, a connecting rod 18 and a straight rod 19. The inner walls on both sides of the corn grain collecting trough 4 are rotatably connected with the rotating rod 16, and the corresponding ends of the two groups of rotating rods 16 are fixedly connected with the disc 17. The corresponding edge positions between the two groups of discs 17 are fixedly connected with the connecting rod 18. Two groups of straight rods 19 are rotatably sleeved on the connecting rod 18. Then the driving motor 5 is started, and the output shaft on the driving motor 5 drives one group of rotating rods 16 to rotate on the inner wall of the corn grain collecting trough 4. The disc 17 drives the other group of discs 17 to rotate through the connecting rod 18. The connecting rod 18 rotates the two groups of straight rods 19 around the circumference of the two groups of discs 17 through the synchronous rotation of the two groups of discs 17.

[0033] The ends of the two groups of straight rods 19 facing away from the connecting rod 18 are hinged to the hinge seat 15, and the end of one group of rotating rods 16 extends out of the corn harvester 1 and is fixedly connected to the output shaft of the driving motor 5. The hinge seat 15 drives the collecting iron box 9 and the two groups of rocking arms 10 to swing left and right in the corn grain collecting trough 4 due to the rotation of the two groups of straight rods 19.

[0034] Working principle: When in use, the fallen corn is first harvested by the corn harvesting auxiliary device 3, and then the corn kernels on the corn are conveyed to the flow plate 8 through the conveyor belt 2. The flow plate 8 is set in an inclined shape to allow the corn kernels to slide through the empty slots 7 on the baffle plate 6 into the collecting iron box 9. When the collecting iron box 9 is full of corn kernels, the magnetic suction plate 12 is pushed, so that the magnetic suction plate 12 drives the sealing plate 11 to slide on the collecting iron box 9 until one side of the magnetic suction plate 12 is bonded to the side of the collecting iron box 9 due to magnetic force. The cylindrical block 13 on the sealing plate 11 prevents the sealing plate 11 from sliding out of the collecting iron box 9 during the operation of the corn harvester 1. The drive motor 5 is then started outside the iron box 9. The output shaft on the drive motor 5 drives one group of rotating rods 16 to rotate on the inner wall of the corn kernel collecting trough 4. The disc 17 drives the other group of discs 17 to rotate through the connecting rod 18. The connecting rod 18 rotates the two groups of straight rods 19 around the circumference of the two groups of discs 17 through the synchronous rotation of the two groups of discs 17. The hinge seat 15 drives the collection iron box 9 and the two groups of rocking arms 10 to swing left and right in the corn kernel collecting trough 4 due to the rotation of the two groups of straight rods 19, so that the corn kernel debris in the collection iron box 9 is screened by the multiple groups of corn holes 14 and falls into the corn kernel collecting trough 4 for collection.

[0035] 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.
