Abstract
A grain handling device for the receiving and transporting of grain and the like with the primary aspects of this invention being related to ground level receiving of such grain from a carrier, such as a truck, holding and controlling such grain and transporting such grain to a storage bin, typically at an elevation higher than that of the grain delivery carrier. The primary aspects of this invention are the positive control of the grain received from the truck into the grain receiving bin through the use of a valve disposed in the grain bin at the outlet thereof for control of the rate of flow of the grain from the grain holding bin into a grain transport. The valve is configured in a unique way to cooperate with sloping bin walls and the bin outlet to substantially seal such outlet in the valve closed position and to prevent bridging of grain within the grain receiving bin, thereby eliminating plugging at the grain bin outlet. In addition, the valve has a grain confronting prow which allows easy manual opening of the valve at such time as the grain receiving bin is completely filled with grain, covering the valve. Of particular importance is the location of the valve within the grain receiving bin whereby the grain is completely emptied from the grain receiving bin, thereby eliminating the need to clean the bin between uses or between handling of different types of grain.
