    摘要： A material metering device having a discrete flow rate adjustment and indicator mechanism. The indicator includes an actuator knob which is rotated to adjust the flow rate of material from the meter. The actuator knob is also operably connected to a follower wheel which is rotated by movement of the actuator knob. Indicia on both the actuator knob and follower wheel are simultaneously registerable with a reference point, such as a viewing window, and the reading of the indicia at the reference point indicates the flow rate of material from the meter.

    摘要： In a seed meter in which a pressure differential is utilized in conjunction with a rotating seed disk having a circumferential row of seed cells therein to pick up individual seeds from a seed mass and deliver the seeds to a seed discharge area, the seed cells are uniquely configured for use with seeds such as sunflower seeds which are of relatively long and slender configuration and of relatively low mass. Each seed cell includes a teardrop shaped recess in the side surface of the disk having an aperture extending through the disk from the bottom thereof to communicate the pressure differential to a seed held within the recess. The seed cell includes a projection extending outwardly from the side surface of the disk and having a surface generally continuous with the back wall of the seed cell so as to aid in picking up and retaining a seed within the recess in addition to providing agitation of the seed mass prior to pickup of the seed. The projection has a sloping top surface to facilitate removal of excess seeds, a beveled outer edge to avoid pressing a seed against the inner wall of the seed meter housing and a sharp inner front edge to prevent excess seeds from lodging between the projection and a fin disposed adjacent and radially inwardly from the recess of the seed cell.

    摘要： An air seed meter which dispenses individual seeds supplied by a seed hopper into a furrow at a controlled rate as the meter and others like it are advanced over the ground has a generally cylindrical housing containing a rotatable seed disk. As the seed disk is rotated past a mass of seeds on one side thereof, a plurality of seed cells formed by recesses in the surface of the seed disk at one or more circumferential rows of holes adjacent the outer periphery of the seed disk mechanically accelerate and eventually capture therein individual seeds from the seed mass. The individual seeds are held within the cells by a pressure differential created by a vacuum source coupled to the inside of the housing on the opposite side of the seed disk until the cells reach a discharge area. At the discharge area, the effects of the vacuum are cut off so as to release the individual seeds from the cells for discharge through a chute at the bottom of the housing to a seed furrow below. Agitation of seeds within the seed mass with the accompanying mechanical acceleration and capture of individual seeds within the cells may be enhanced by providing fins on the surface of the seed disk and is facilitated by a cell configuration which has a rear wall of greater slope than the front wall of the cell. Doubling of seeds within the individual cells is minimized by limiting the size and depth of the cells relative to the seed and also by use of a relatively low pressure differential which is made possible by the manner in which the cells agitate, mechanically accelerate and then capture the seeds. As a result there is no need for cumbersome and elaborate multiple seed eliminating arrangements.
