Vibratory feeding mechanism of grain selection separator

Abstract

The invention relates to a vibratory feeding mechanism of a grain selection separator, and belongs to the technical field of cleaning and grading of grain. The vibratory feeding mechanism comprises a machine frame of a frame structure. The vibratory feeding mechanism is characterized in that a vibrating board is arranged on the machine frame in an inclined mode, the upper right portion of the vibrating board is the grain entering end, the lower left end of the vibrating board is the grain feeding end, the upper right end of the vibrating board is hinged to the right side of the machine frame, the lower left end of the vibrating board is connected to the left side of the machine frame through an elastic part, and a vibrating motor is arranged at the bottom of the vibrating board. By means of the vibratory feeding mechanism, under the action of the vibrating motor, a vibration rotating shaft, an anti-impact check block and a spring, the purpose that the grain is controlled in a stable zero-degree feeding state is achieved. When the vibratory feeding mechanism is applied, by adjusting the input voltage of input frequency of the vibrating motor, the amplitude or vibrating frequency can be adjusted correspondingly, and adjustment and control of feeding quantity can be achieved.

Description

technical field [0001] The invention relates to a vibrating feeding mechanism of a grain sorting separator, which belongs to the technical field of grain cleaning and grading. Background technique [0002] At present, the feeding mechanism of the existing grain wind separation, impurity removal and grading equipment generally adopts self-flowing mechanism, impeller type, belt type, and screw auger type. Due to the inertia of the machine, the grain cannot be controlled in a stable zero-degree feeding state. At the same time, due to the unstable air volume of the fan, the feeding volume often increases or decreases suddenly, which affects the removal of impurities and increases the grading of grain. Contents of the invention [0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is: to provide a vibrating feeding mechanism of a grain selection separator, which has a simple structure and ensures that the grai...

[0002] At present, the feeding mechanism of the existing grain wind separation, impurity removal and grading equipment generally adopts self-flowing mechanism, impeller type, belt type, and screw auger type. Due to the inertia of the feed, the grain cannot be controlled at a stable zero-degree feeding state. At the same time, due to the unstable air volume of the fan, the feed volume often increases or decreases suddenly, which affects the removal of impurities and increases the grading of the grain.
