A slant cricket groove drilling mechanism for a corn harvester threshing device

Abstract

The invention provides an inclined plate ball groove drilling mechanism of a corn harvester threshing device. The inclined plate ball groove drilling mechanism aims at solving the problem that due to the fact that a semi-mechanized corn harvester mechanism on the market does not have the threshing function, the development requirement can not be met. The inclined plate ball groove drilling mechanism of the corn harvester threshing device is characterized in that a driving mechanism is fixed to the right side of a rotating shaft, the rotating shaft is sleeved with a left bearing pedestal and a right bearing pedestal, the left bearing pedestal and the right bearing pedestal are fixed to a left machine frame plate and a right machine frame plate, an upper angle type support and a lower angle type support are arranged on the upper machine frame plate and the lower machine frame plate, an upper inclined type positioning plate and a lower inclined type positioning plate are fixed to the upper angle type support and the lower angle type support respectively, a ball groove inclined plate is arranged on the right side of the rotating shaft in a sleeving mode and fixed to the upper inclined type positioning plate and the lower inclined type positioning plate, a ball groove is formed in the ball groove inclined plate, a rotating disc is fixed to the left side of the rotating shaft, a clamp is arranged on the rotating disc, a drill bushing is arranged on the right side of the clamp, the front end of a drill bit is sleeved with the dill bushing, the rear end of the drill bit is connected with a swing rod, and a swing head is arranged at the tail end of the swing rod and placed in the ball groove of the ball groove inclined plate. The inclined plate ball groove drilling mechanism has the direct threshing function, and full mechanization of the corn harvester mechanism is achieved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a slant ball groove drilling mechanism of a corn harvester threshing device. Background technique [0002] With the development of mechanization, the semi-mechanized corn harvester mechanism in the market cannot adapt to the needs of development because it does not have the function of direct threshing. To realize the full mechanization of the corn harvester mechanism, it is necessary to increase the direct threshing function, and it is necessary to increase the direct threshing function in the harvester. Drilling mechanism for drilling and coring. Contents of the invention [0003] In order to solve the problem that the semi-mechanized corn harvester mechanism in the market does not have the function of direct threshing and cannot meet the needs of development, this invention proposes a slant ball groove drilling mechanism for the corn harvester threshing device, which no...
