The improvements include means for preventing wedging of the crop material between the revolvable paddle-gate, such as a rearwardly swinging upright door and a rearwardly flared underlying trough both at the chute rear-end. Also disclosed are improved stopmeans for steading and then releasing the revolvable paddle-gate, the stop-means being vertically adjustable and including a frontal toggle portion to prevent reverse directional turning of the paddle-gate member.,下面是Weighing and measuring apparatus for fodder and similarly course materials专利的具体信息内容。

1. A weighing and measuring apparatus especially adapted for heavy batches of fodder, silage, and similarly course material and comprising: A. An upright chute having an open upright front-end to accommodate the paddles of a revolvable and vertically movable paddle-gate member and open top-end and bottom-end for respectively charging and discharging the material to be weighed, the chute comprising an upright left-panel and an upright right-panel having a fixed transverse distance therebetween, a planar upright door closure along the chute rear-end upper portion and having the door upper part pivotal about a horizontal transversely extending door-axis whereby the door pivotably swings rearwardly during paddle-gate revolvable ejection of a weighed batch, said upright door including a substantially horizontal transversely extending lower-edge, stabilization means for maintaining the door upright during charging of a material batch, and said chute further comprising a rearwardly flared trough spaced below the door lower-edge and converging toward the chute open bottom-end to direct a weighed batch downwardly-forwardly theretoward after having been ejected by the paddle-gate through the rearwardly swinging door; B. A generally horizontal balancing bail including transversely separated side arms located externally along the left-panel and the right-panel and further including a horizontal intervening bight portion located externally of the chute rear-end, said bail side arms having intermediate portions pivotably attached along a transversely extending horizontal bail-axis to the chute left-panel and right-panel, and a weighing beam member extending rearwardly from the bail bight portion; C. A paddle-gate member located within the chute having a transversely extending and vertically reciprocatable paddleaxis that is revolvable secured to the bail side arms forwardly of the bail-axis, said paddle-gate member having more than two spaced apart paddle members extending radially outwardly from the paddle-axis, each paddle having a pair of transversely separated exposed radial free-edges which are spaced a finitegap inwardly away from the chute left-panel and right-panel; and D. Stop-means for the uprighted paddles and secured within said chute at a level above said vertically reciprocatable paddleaxle and spaced therefrom a distance approximately equivalent to the radial dimension of the respective paddles.
2. The weighing and measuring apparatus of claim 1 wherein the stabilization means for maintaining the door upright during charging of a material batch comprises a weighty door that tends to depend weightily downwardly from the door-axis together with at least one abutment means attached to and extending transversely outwardly of the door to forwardly abut upright rearward portions of the chute.
3. The weighing and measuring apparatus of claim 2 wherein the rearwardly flared trough is spaced below the bail horizontal bight portion; and wherein the weighing beam member includes a slidable weight therealong to determine the weight of each ejected and discharged batch.
4. The weighing and measuring apparatus of claim 3 wherein the stop-means is of the toggle type and secured inside said chute and comprising an elongate bar of adustable vertical height, there being a toggle pivotably attached to a frontal portion of the elongate bat to prevent forward revolving of the paddle-gate member during batch weighing.
5. A weighing and measuring apparatus especially adapted for heavy batches of agricultural crop such as fodder, silage, and other crops, and the apparatus comprising: A. An upright chute having an open upright front-end to accommodate the radial panels of a revolvable paddle-gate member and open top-end and bottom-end for respectively charging and discharging the material to be weighed, the chute also comprising transversely separated left-panel and right-panel and also a closed rear-end; B. A generally horizontal balancing bail including transversely separated side arms located externally along the left-panel and the right-panel and further including a horizontal intervening bight portion located externally of the chute rear-end, said bail side arms having intermediate portions pivotably attached along a transversely extending horizontal bail-axis to the chute left-panel and right-panel, and a weighing beam member extending rearwardly from the bail bight portion; C. A paddle-gate member located within the chute having a transversely extending and vertically reciprocatable paddle-axle that is revolvably secured to the bail arms forwardly of the bail-axis, said paddle-gate member having more than two spaced apart paddle members extending radially outwardly of transverse paddle-axis; and D. At least one stop-means for the successively uprighted paddles and located within said chute at a level above said vertically reciprocatable paddle-axle and spaced upwardly therefrom a distance approximately equivalent to the radial dimension of the respective paddles, the stop-means comprising an elongate bar of vertically adjustable height and having fore-end, which bar fore-end is adapted to abut a paddle remote-end to prevent paddle-gate rearward turning at its material charging upward-station but not at the fully charged downward-station thereof, a toggle upwardly pivotably associated with the bar forward portion to admit the paddle transverse remote-end between it and the bar fore-end and having a normal-station depending of the bar to stationarily confine the paddle and the entire paddle-gate member from revolving forwardly during chargeable weighing of a material batch.
6. The weighing and measuring apparatus of claim 5 wherein the elongate bar of the stop-means including the associated toggle is of adjustable vertical height to compensate for misalignment of the revolvable paddle-gate member.
7. The weighing and measuring apparatus of claim 6 wherein the stop-means elongate bar is substantially horizontal and parallel to the chute left-panel, a medial part of the elongate bar being pivotably attached to the chute left-panel, spring means suspendably attaching the elongate bar rear-end to the chute left-panel, and gradual pressure-application means extending downwardLy from the chute left-panel to the stop-means bar between its pivotal and spring connections to the left-panel to stably adjust the vertical height of the stop-means.
8. The weighing and measuring apparatus of claim 6 wherein there is an upright door closure along the chute rear-end upper portion and having the door upper part pivotal about a horizontal transversely extending door-axis whereby the door pivotably swings rearwardly during paddle-gate revolvable ejection of a fully charged batch, said upright rear door including a substantially horizontal transversely extending lower-edge, stabilization means for maintaining the door upright during material charging onto the stationary paddle-gate member, and said chute further comprising a rearwardly flared trough spaced below the door lower-edge and converging toward the chute open bottom-end to direct a fully weighed batch downwardly-forwardly theretoward after having been rearwardly revolvably ejected by the fully charged paddle-gate member and at least partially through the rearwardly swingable door.
9. The weighing and measuring apparatus of claim 7 wherein the chute volume exceeds about 25,000 cubic inches; and wherein there is another said elongate bar and toggle type stop-means and positioned at the chute right-panel and at co-elevation with said left-panel stop-means.
10. The weighing and measuring apparatus of claim 9 wherein the rear door stabilization means comprises a weighty door, there being at least one abutment ear attached to and extending transversely outwardly of the door to forwardly abut upright rearward portions of the chute; wherein the chute volume exceeds about 25,000 cubic inches; and wherein there is a pair of said elongate bar and toggle-type stop-means respectively positioned at the chute left-panel and right-panel.
