| 摘要 | A grain stirring device includes an endless flexible conveyor which is mounted on a supporting structure for movements about a circuitous path and for rotation of the circuitous path on a vertical axis within a circular grain drying bin and power means is provided to impart the circuitous and rotational movements upon proper energization of the power means. | ||||||
| 权利要求 | 1. Grain stirring apparatus for use in a grain drying bin having a circular outer wall, a top wall and a bottom wall, said grain stirring apparatus comprising: a. a flexible endless conveyor; b. support means mounting said conveyor for movement about a circuitous path and for rotation of the circuitous path within said said drying bin; and c. power means for providing said circuitous movement and said rotational movement upon proper energization thereof. 2. Grain stirring apparatus for use in a grain drying bin having a circular outer wall, a top wall and a bottom wall, said grain stirring apparatus comprising: a. a flexible endless conveyor; b. support means for said conveyor; c. said flexible endless conveyor being mounted on said support means for movements in a circuitous path of travel; d. means mounting said support means for rotation on a vertical axis generally parallel to the vertical axis of the grain drying bin; e. power means operatively mounted to impart said circuitous movements to said conveyor; and f. independent power means for imparting said rotational movement to said support means. 3. The structure of claim 2 in which said circuitous path of travel lies in a plane which generally extends radially from the vertical axis to the circular outer wall generally between the upper and lower wall of the grain drying bin. 4. The structure of claim 2 in which said support means mounting said conveyor for movements in a circuitous path includes: a. a vertically disposed tubular element; b. a first guide portion extending radially from said tubular element mounting said flexible conveyor for movements generally radially outwardly adjacent the bottom wall of the grain drying bin; and c. a second guide portion extending vertically from the radially outer end of said first portion and mounting said conveyor for movements vertically upwardly adjacent the circular outer wall of said grain drying bin. 5. The structure of claim 4 in further combination with means for disabling said independent power means responsive to deflection of said second portion of said support means adjacent said circular outer wall a given amount of degrees from the vertical during circumferential movement of said portion relative to said circular outer wall. 6. The structure of claim 5 in which said independent power means includes an electrically operated motor and in which said means for disabling said independent power means is a mercury switch adjustably mounted on said second portion of said support means adjacent the upper end thereof, said mercury switch being mounted to terminate the supply of electrical energy to said electrically operated motor responsive to deflection of said second portion of said support means a given amount of degrees from the vertical during said circumferential movement of said second portion. 7. The structure of claim 2 in which said tubular element defines the vertical axis of rotation of said support means and is coaxially disposed with respect to the vertical axis of the grain drying bin. |
