摘要： This invention relates to a cultivating shank assembly in which a mounting frame is comprised of a mounting frame portion and a tool shank support portion pivoted thereon. The mounting frame portion and the tool support portion are formed of plates which are held together by suitable transversely extending plates which support the mounting frame on a cultivating tool bar and mount the tool shank respectively. A compression spring for the mounting assembly is connected between the tool shank portion and the mounting frame portion of the mounting frame and is guided between inner and outer cylindrical spring retainers which are pivoted respectively on the tool shank support portion and the mounting frame portion to prevent the compression spring from buckling and to guide the same such that the compressive force will always be applied along the extent of the spring. Suitable apertures in the mounting frame portion provide a limit stop to define the pitch adjustment of the tool shank and provide preload adjustment for the compression spring.
摘要翻译：本发明涉及一种栽培柄组件，其中安装框架由安装框架部分和枢转在其上的工具柄支撑部分组成。安装框架部分和工具支撑部分由板组成，它们通过合适的横向延伸板保持在一起，该板将安装框架分别支撑在栽培工具杆上并分别安装工具柄。用于安装组件的压缩弹簧连接在工具柄部分和安装框架的安装框架部分之间，并且在分别在工具柄支撑部分和安装框架部分上枢转的内圆柱形弹簧保持器和外圆柱形弹簧保持器之间被引导以防止压缩弹簧从弯曲并引导，使得压缩力将始终沿着弹簧的程度施加。安装框架部分中的合适的孔提供了限制止挡件以限定工具柄的俯仰调整并且为压缩弹簧提供预载调整。

摘要： An automatic reset plow assembly includes a plow frame drawn by an agricultural vehicle. A plow standard is pivotally connected to the underside of the frame to enable the plow share to pivot backwardly and upwardly upon engaging an obstruction in the soil. The plow standard is resiliently biased downwardly by a toggle link assembly having one link pivotally connected to the plow standard and a second link pivoted to the frame. The other ends of the two links are pivotally connected together and to a slide element to form the elbow of the toggle link. The slide element is slideably received along a guide member which is also pivotally mounted to the frame. A compression spring surrounds the guide and resiliently biases the slide element and toggle links to maintain the plow standard in a normally downwardly pivoted plowing position. Upon encountering an obstruction, the plow pivots rearwardly and collapses the toggle link assembly. After the plow passes the obstruction, the spring returns the toggle link assembly and plow to their normal operative position. A damper assembly is optionally provided at the connection between the frame and second link to reduce shock resulting from the return of the plow from its tripped positioned to its operative plowing position.
摘要翻译：自动复位犁组件包括由农用车辆牵引的犁架。犁式标准杆可枢转地连接到框架的下侧，以使犁耕部分在接合土壤中的障碍物时向后和向上枢转。犁标准由具有枢转地连接到犁耕标准的一个连杆的肘节连杆组件和枢转到框架的第二连杆向下弹性偏压。两个连杆的另一端枢转地连接在一起并且连接到滑动元件以形成肘节连杆的弯头。滑动元件沿着也被枢转地安装到框架的引导构件可滑动地容纳。压缩弹簧围绕引导件并弹性地偏置滑动元件和肘节连杆，以将犁式标准保持在正常向下枢转的耕作位置。在遇到障碍物时，犁向后枢转并折叠肘节连杆组件。在犁过障碍物之后，弹簧返回肘节连杆组件并犁到其正常的操作位置。阻尼器组件可选地设置在框架和第二连杆之间的连接处，以减少由于犁从其跳闸定位到其操作耕作位置而引起的冲击。

摘要： A mounting structure for support from an implement frame and including first and second brackets supported on the frame in transversely spaced relation and the first bracket includes an anchor portion oscillatably supported therefrom for rotation about an axis extending between the brackets. The anchor portion includes structure for anchoring one end of an implement therefrom and an elongated torsion bar extends between the brackets and has one end thereof supported from the second bracket for adjustable angular positioning about the longitudinal axis of the torsion bar, the second end of the torsion bar being keyed to the anchor portion for oscillation therewith.

摘要： A HINGED PRESSURE RELEASABLE CONNECTING MEANS IS PROVIDED TO JOIN THE FRAME OF AN AGRICULTURAL IMPLEMENT TO THE BEAM WHICH SUPPORTS THE IMPLEMENT. THE CONNECTING MEANS COMPRISES A PRESSURE DEVICE CONNECTED AT ONE END TO A TWO-ARMED LEVER. THE PRESSURE DEVICE MAY BE CONNECTED TO THE IMPLEMENT BEAM, AND THE LEVER ARRANGED TO COOPERATE WITH THE IMPLEMENT FRAME, OR THE POSITIONING CAN BE REVERSED. BY A SUITABLE CHOICE OF THE RELATIVE LENGTHS OF THE ARMS OF THE TWO-ARMED LEVER AND OF OTHER LINK MEANS THERE BY BE OBTAINED AN ACCURATE SETTING OF THE PRESSURE REQUIRED TO RELEASE THE CONNECTING MEANS.

摘要： A tillage implement having a plurality of spaced ground-working tools, with safety trip means for each tool allowing the tool to move from a normal ground-penetrating position to a position elevated thereabove when an obstruction, such as a rock or a stump, is encountered. Each ground-working tool is mounted for free-swinging movement between the ground-penetrating position and a fully elevated position above the ground, and the tool is positively guided to and from the ground-working position, with the guiding means functioning to allow the ground-working tool to initially move out of the ground-penetrating position without substantial downward movement into the ground, and with the guiding means also functioning to direct the ground-working tool back into the ground at the proper angle of reentry. Hydraulic cylinder means continuously biases each tool toward the groundpenetrating position, with the hydraulic cylinder means yieldably resisting movement of the tool away from the ground-penetrating position and returning the ground-working tool into the groundpenetrating position after the obstruction has been cleared.
