Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a corn cob collection device for harvesters. Background Technology

[0002] The corn cob collection device for harvesters is a key component of corn harvesters used for the automatic separation, conveying, and centralized collection of residual corn cobs after threshing. Its main function is to solve the problem of corn cob mixing with kernels during the threshing process, achieving efficient recycling and reuse of waste.

[0003] In the prior art, such as application number 202420208518.3, entitled "Corn Cob Collection Device for Corn Threshing Machine," the corn cobs after threshing are directly transported to a transport vehicle or designated location via a conveyor belt. However, in actual use, this device has the following drawbacks:

[0004] 1. A single conveyor belt cannot transport the threshed corn cobs to the designated location, making it impossible to quickly collect and load the corn cobs onto trucks.

[0005] 2. When the conveyor belt is at a certain conveying angle, it cannot effectively transport the corn cobs.

[0006] 3. Unable to effectively separate corn cob and corn husk.

[0007] This invention addresses these issues by proposing a corn cob collection device for harvesters, aiming to solve the aforementioned problems. The device enables rapid collection and loading of corn cobs, provides excellent corn cob conveying performance, and allows for quick and effective separation of threshed corn cobs from corn husks.

[0038] The first and second transmission units are driven synchronously by a driving component.

[0039] The driving component includes a motor 8, a support plate 1 9, a support plate 2 10, a rotating shaft 1, and a rotating shaft 2. The support plate 1 9 and the support plate 2 10 are respectively rotatably connected to the rotating shaft 1 and the rotating shaft 2. The rotating shaft 1 is provided with a sprocket 1 11 and a sprocket 2 12. The rotating shaft 2 is provided with a sprocket 3 13 and a synchronous pulley 14. The support plate 1 9 is provided with a motor 8, which drives the rotating shaft 1 to rotate. The sprocket 1 11 is connected to the sprocket 3 13 via a chain 1.
