摘要： A seeding machine is provided with banks of individual seed hoppers for directing seed to auxiliary seed hoppers located on individual planting units. The individual seed hoppers of each bank are provided with adjoining walls. The adjoining walls have notches so that seed in one individual seed hopper can flow into an adjoining individual seed hopper. A portion of the planting units can be disabled by placing them in a non-working position. The individual seed hoppers supplying seed to the disabled planting units are provided with removable baffles. Each removable baffle is provided with a downwardly extending leg that cooperates with the notches to prevent seed in an active individual hopper from entering an inactive individual hopper.

摘要： The invention provides a method of reducing plugging of a no-till seeder with crop residue by guiding the furrow openers of the seeder between the standing stubble rows of the previous crop. A guidance system is provided comprising sensing means to sense the standing stubble rows from the previous crop and to send a steering signal in response to changes in the relative position of the seeder to the standing stubble rows; and adjusting means to adjust the travel path of the seeder in response to the steering signals. The sensing means can sense the location of the standing stubble rows by contact therewith or by sensing the furrow from which the standing stubble rows extend. The position of the seeder relative to the towing vehicle is adjusted in response to steering signals sent by the sensing means.
摘要翻译：本发明提供了一种通过将播种机的开沟机引导在先前作物的直立茬行之间来减少免耕播种机与作物残渣的堵塞的方法。提供了一种引导系统，其包括感测装置，用于感测来自前一作物的站立茬行并且响应于播种机相对于站立茬行的相对位置的改变发送转向信号; 以及调节装置，以响应于转向信号来调节播种机的行进路径。感测装置可以通过与其接触或通过感测直立茬行延伸的沟槽来感测站立的茬行的位置。播种机相对于牵引车辆的位置响应于由感测装置发送的转向信号而被调整。

摘要： The invention comprises an improvement for finger type seed meters. The improvement is a backing or wear plate of lubricious material with a seed release and an exit. The improved also has a cutout section and a plurality of variable inserts to get accurate seed spacing of a variety of size and shapes of seeds. Each insert of the meter includes a seed release area having varied shapes and depths of projections and depressions to accomplish accurate and timely release from the fingers of seeds of various sizes and shapes. Each insert also has an improved seed exit or void. The exit void being varied both in dimension and contour to substantially eliminate seed rejections and to ensure seed ejection into a seed tube and thence to the soil.
