Description

Technical Field

[0001] The utility model relates to the field of corn harvester equipment, in particular to a corn divider structure of a corn harvester. Background Art

[0002] The straw divider is a key component in agricultural machinery and equipment, especially playing an important role in corn harvesters and other crop harvesters; its main function is to prop up the fallen corn plants and gather the deviated corn plants so that they can move relative to the machine along the inclined surface of the straw divider and enter the clamping channel.

[0003] However, the distance between the dividers cannot be adjusted when they are in use, resulting in a fixed spacing between the dividers. When the corn stalks are thick, they are easily stuck between the dividers, causing inconvenience in harvesting. At the same time, when the distance between the dividers is wide, it is easy for multiple corn stalks to enter between the dividers at the same position, affecting the harvesting effect. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

When in use, the power mechanism drives the second screw to rotate, so that the first screw rotates, and the second straw divider moves along the first screw and the second screw respectively. Since the thread pitches of the first screw and the second screw are in a multiple relationship, when the second straw divider close to the first straw divider moves one unit distance, the second straw divider close to the second straw divider moves two unit distances. In this way, the distances between the straw dividers are equal after adjustment, which is convenient for practical use of corn stalks of different diameters and improves the practicality of the device.

After the adjustment is completed, the second screw is prevented from rotating in the opposite direction, thereby ensuring the normal and stable use of the grain divider.

[0007] Preferably, the fixing plate is a U-shaped plate.

[0020] See also Figure 1-4 The utility model provides a grain divider structure of a corn harvester, including a fixed plate 1 and a first grain divider 4. The fixed plate 1 is a U-shaped plate. An extension block 8 is welded and fixed on one side of the fixed plate 1. The first grain divider 4 is fixed to one side of the extension block 8 by bolts. A movable shaft 5 is movably inserted into the lower end of the first grain divider 4. A positioning rod 3 is welded and fixed on the inner side of the fixed plate 1. The positioning rod 3 movably passes through the lower end of the first grain divider 4. First screws 6 are welded and fixed on both sides of the movable shaft 5. A second screw 7 is welded and fixed on the outer side of the first screw 6. The thread pitch of the first screw 6 is smaller than the thread pitch of the second screw 7, and they are in a multiple relationship. The outer sides of the first screw 6 and the second screw 7 are both connected with a second grain divider 11 through a threaded sleeve. The second screw 7 One side is movably embedded in the inner side of the fixed plate 1, and the positioning rod 3 movably passes through the lower end position of the second crop divider 11. One side of the fixed plate 1 is provided with a power mechanism for conveniently driving the second screw 7 to rotate. When in use, the power mechanism drives the second screw 7 to rotate, so that the first screw 6 rotates, and the second crop divider 11 moves along the first screw 6 and the second screw 7 respectively. Since the thread pitches of the first screw 6 and the second screw 7 are in a multiple relationship, when the second crop divider 11 close to the first crop divider 4 moves a unit distance, the second crop divider 11 close to the second crop divider 11 moves two unit distances.

The motor 9 is fixed to one side of the fixed plate 1 through a mounting frame, the worm 10 is fixed to the output end of the motor 9 through a coupling, and the worm wheel 2 is fixed to one side of the second screw 7 through a coupling. The worm wheel 2 is meshed with the worm 10. When in use, the motor 9 is started, and the motor 9 drives the worm 10 to rotate, so that the worm wheel 2 rotates, thereby driving the second screw 7 to rotate, thereby adjusting the spacing between the grain dividers, and the worm wheel 2 cannot drive the worm 10 to rotate. After the adjustment is completed, the second screw 7 is prevented from rotating in the opposite direction, thereby ensuring the normal and stable use of the grain divider.

[0022] Working principle: when in use, the power mechanism drives the second screw 7 to rotate, so that the first screw 6 rotates, and the second crop divider 11 moves along the first screw 6 and the second screw 7 respectively. Since the thread pitches of the first screw 6 and the second screw 7 are in a multiple relationship, when the second crop divider 11 close to the first crop divider 4 moves one unit distance, the second crop divider 11 close to the second crop divider 11 moves two unit distances. In this way, the distances between the crop dividers are equal after adjustment, which is convenient for practical use of corn stalks of different diameters and improves the practicality of the device; when in use, the motor 9 is started, and the motor 9 drives the worm 10 to rotate, so that the worm wheel 2 rotates, thereby driving the second screw 7 to rotate, thereby adjusting the spacing between the crop dividers, and the worm wheel 2 cannot drive the worm 10 to rotate. After the adjustment is completed, the second screw 7 is prevented from rotating in the opposite direction, thereby ensuring the normal and stable use of the crop divider.
