Description

Technical Field

[0001] The utility model relates to the technical field of corn harvester devices, in particular to a conveyor chain adjusting device for a corn harvester. Background Art

[0002] The conveyor chain adjustment device of the corn harvester is an agricultural machine that mechanically completes the harvesting of corn stalks according to agronomic requirements when the corn is mature or nearly mature.

[0003] The existing corn harvester cannot change the machine according to the height of the silo when loading, so it can only be fixed during use. After the machine is used for a long time, the gears and chains may become loose, but traditional equipment cannot detect it. Therefore, we propose a corn harvester conveyor chain adjustment device. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the utility model provides a corn harvester conveyor chain adjustment device, which has the advantages of easy adjustment and easy lifting, and solves the problems raised by the above background technology.

[0005] The utility model provides the following technical solution: a corn harvester conveyor chain adjustment device, comprising a base plate, a loader and a lifting assembly are respectively provided on the top of the base plate, a storage box is fixedly installed on the top of the base plate, a controller is fixedly installed on the outer wall of the loader, the inner wall of the loader is transmission-connected with a chain, and the inner wall of the chain is provided with an adjustment assembly.

[0006] As a preferred technical solution of the present invention: the controller is electrically connected to the electric push rod, the top of the bottom plate is fixedly installed to the bottom of the base, and the outer wall of the loader is fixedly installed to the outer wall of the fixed plate.

[0007] As an optimal technical solution of the present invention: the adjustment component includes a round rod, a cylinder is fixedly installed on the outer wall of the round rod, a fixed column is fixedly installed on the outer wall of the cylinder, a long rod is fixedly installed on the outer wall of the fixed column, and a fixed plate is slidably connected to the outer wall of the long rod. An elastic part is provided at the bottom of the fixed plate, and a slide is fixedly installed on the top of the elastic part.

[0008] As a preferred technical solution of the present invention: the outer wall of the elastic member is wrapped around the outer wall of the long rod, the outer wall of the slide plate is slidably connected to the outer wall of the long rod, and the outer wall of the fixed column is in contact with the inner wall of the chain.

[0009] As an optimal technical solution of the present utility model: the lifting assembly includes a base, an electric push rod is fixedly installed on the outer wall of the base, a rack is fixedly installed on the telescopic end of the electric push rod, a gear is meshed with the outer wall of the rack, a support rod is fixedly installed on the outer wall of the gear, a gear ring is fixedly installed on the outer wall of the support rod, a sliding rod is meshed with the outer wall of the gear ring, the outer wall of the sliding rod is slidably connected to a circular ring, the outer wall of the circular ring is fixedly installed with a shell, the outer wall of the sliding rod is fixedly installed with a limiting rod, and the outer wall of the limiting rod is rotatably connected to a fixed seat.

[0010] As an optimal technical solution of the present invention: the sliding rod is slidably connected to the inner wall of the outer shell through a circular ring, the top of the fixed seat is fixedly installed on the outer wall of the loader, the bottom of the outer shell is fixedly installed on the top of the base plate, and the outer wall of the rack is slidably connected to the outer wall of the base.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The conveyor chain adjustment device of the corn harvester controls the electric push rod by pressing the controller. When the electric push rod starts to extend and retract, a rack is fixedly installed on the telescopic end of the electric push rod, so that the rack can be pushed to slide on the inner wall of the base. At this time, the rack drives the gear to rotate. When the gear rotates, it can drive the support rod to rotate the two sets of gear rings. The outer wall of the gear ring is meshed with a sliding rod, which is slidably connected to the inner wall of the shell through the circular ring, so that the sliding rod can drive the limit rod to rotate the fixed seat. At this time, the fixed seat can change the height of the loader, so that the lifting assembly can lift the loader to adapt to granaries of different heights.

[0013] 2. The corn harvester conveyor chain adjustment device contacts the inner wall of the chain through a fixed column. When the chain becomes loose, the originally compressed elastic part and the fixed column press forward against the inner wall of the chain. When the fixed column moves forward, it can drive the long rod to move forward, so that the elastic part is relaxed. At this time, the elastic part can drive the slide forward, so that the fixed column can lift the chain, making the chain taut, and the problem of chain loosening will no longer occur.

[0032] In the above structure, when the electric push rod 702 starts to extend and retract, a rack 703 is fixedly installed on the telescopic end of the electric push rod 702, so that the rack 703 can be pushed to slide on the inner wall of the base 701. At this time, the rack 703 drives the gear 704 to rotate. When the gear 704 rotates, it can drive the support rod 705 to rotate the two sets of gear rings 706. The outer wall of the gear ring 706 is engaged with a slide rod 707, so that the slide rod 707 is slidably connected to the inner wall of the shell 709 through the ring 708, so that the slide rod 707 can drive the limit rod 710 to rotate the fixed seat 711. At this time, the fixed seat 711 can change the height of the loader 2.

[0033] Working principle: When the electric push rod 702 starts to extend and retract, the rack 703 is fixedly installed on the telescopic end of the electric push rod 702, so that the rack 703 can be pushed to slide on the inner wall of the base 701.

The outer wall of the gear ring 706 is meshed with a slide rod 707, so that the slide rod 707 is slidably connected to the inner wall of the shell 709 through the ring 708, so that the slide rod 707 can drive the limit rod 710 to rotate. The fixed seat 711 rotates, and the fixed seat 711 can change the height of the loader 2. When the chain 5 becomes loose, the fixed column 603 contacts the inner wall of the chain 5. When the chain 5 becomes loose, the elastic member 607, which was originally compressed, and the fixed column 603 presses forward against the inner wall of the chain 5. When the fixed column 603 moves forward, it can drive the long rod 604 to move forward, so that the elastic member 607 is relaxed. At this time, the elastic member 607 can drive the slide 606 forward, so that the fixed column 603 can lift the chain 5, so that the chain 5 can be tightened.
