Mixed bean extractor disc sawtooth knife vine cutting mechanism

Abstract

The invention discloses a mixed bean extractor disc sawtooth knife vine cutting mechanism and belongs to agricultural machinery. A hanging plate seaming is fixedly mounted on an extractor rack, a hanging frame is mounted on the hanging plate seaming in a hinged manner, a knife rest is mounted on the hanging frame in a hinged manner, a disc sawtooth knife is mounted on the knife rest through a knife disc shaft, a first bevel gear reversing transmission box assembly, an internal spline transmission sleeve and a second bevel gear reversing transmission box assembly connect a power input shaft of an output power transmission system with the knife disc shaft of the disc sawtooth knife, a profiling movement control rod mounted with a pressure spring in a sleeved manner is inserted onto the hanging plate seaming, one side of the profiling movement control rod is hinged to the knife rest, and a divider assembly is mounted on the knife rest through a divider seat. The mixed bean extractor disc sawtooth knife vine cutting mechanism is simple and reasonable in structure, little in operating vibration, low in noise, stable in running, reliable in use, high in efficiency and high in applicability.

Description

Technical field [0001] The invention belongs to agricultural machinery and mainly relates to a vine-breaking operation mechanism on a miscellaneous bean pulling machine. Background technique [0002] At present, various varieties of miscellaneous beans, such as kidney beans, all the varieties of miscellaneous beans with high yield have larger stems and vines. The stems and vines are intertwined during the growth and development process, commonly known as "pan vines". The existing miscellaneous beans are used. When the lifting machine is lifting and harvesting, the mixed bean stalks that are pulled up within the lifting width of the machine and the unpulled bean stalks on the outside of the lifting width are pulled together, causing the tractor to congestion. Failure, the machine cannot work normally, so it is an urgent technical problem to effectively and reliably cut the connection between the uprooted bean stalks within the working width of the machine and the unplugged bean st...

AI Technical Summary

Problems solved by technology

[0002] In the current varieties of miscellaneous beans such as kidney beans, the length of the vines of all high-yielding miscellaneous beans is relatively large, and the stems and tendrils are intertwined and intertwined during the growth and development process, commonly known as "coiled vines". When the pulling machine performs the pulling and harvesting operation, the uprooted miscellaneous bean stems and tendrils within the pulling width of the machine are pulled together with the unpulled miscellaneous bean stems and tendrils on the outside of the lifting operation width, resulting in congestion of the dragging pile of the machine tool Failure, the machine cannot work normally, so it is an urgent technical problem to effectively and reliably cut off the connection between the vines that have been pulled up within the working width of the machine and the vines that have not been pulled up outside the working width of the machine

For this reason, the applicant of this patent has developed a vine-cutting mechanism consisting of an eccentric drive mechanism, a moving blade and a blade guard, which solves the problem of vine-breaking in the operation of pulling up miscellaneous beans, but there are still complex structures and operational vibrations. And the technical defects of high noise and high failure rate need to be solved
