Disk harrow standard for support beams of different cross sections |
摘要 |
A disk bearing standard which may be utilized with support tubes of different cross sections by simply changing a low cost U-bolt which clamps the standard to the tube. The standard includes front and lower locating surfaces formed at an angle of ninety degrees with respect to each other. A bolt-receiving member angles upwardly from the forward surface at an angle of about forty-five degrees and receives an angled leg of the U-bolt. The rear leg of the U-bolt extends downwardly through an elongated slot at the aft end of the lower locating surface. The size of the U-bolt is selected according to the size of the mounting tube, and the U-bolt clamps the standard in two planes perpendicular to each other to prevent misalignment of the standard when loads are applied. A rearwardly extending appendage provides a scraper tube mounting which is fixed with respect to the center line of the disk blades regardless of the selected size of the mounting tube.
