摘要： In the case of a soil cultivation device with multiple harrow tines, the harrow tines are fastened to levers, which are mounted to pivot on tie bars of the supporting frame via carriers. The operating position of the harrow tines is defined by the levers being adjacent to tie bars, and the harrow tines are prestressed into the operating position by springs assigned to them in the form of pneumatic cylinders.

摘要： A harrow attachment for a tillage implement includes a harrow drawbar mounting at least one rank of harrowing tools. A pivot link pivotally couples the harrow rank to the drawbar so it can trip by pivoting upward toward the drawbar from a home position in which the harrow rank is farthest away from the drawbar. A downforce spring is coupled to the drawbar and in a variable length state when the harrow rank is tripped to apply a return biasing force to the harrow rank. An adjustment mechanism couples the spring to the harrow rank and/or the pivot link in one of a plurality of adjustment locations in each of which the harrow rank is in the home position and the spring is in a fixed length state in which the biasing force is removed.

摘要： A tine harrow has a plurality of harrow tines mounted on and downwardly depending from a harrow frame. The tines are configured to be moveable between a lowered position and a raised position, and at least one tine lowerable or raiseable to a different relative position in relation to a surface of a field than others of the tines. The ability to lower and raise individual tines or rows of tines to different positions in relation to a surface of a field provides more effective response of the tine harrow to changing land conditions. The positions to which individual tines or rows of tines are lowered or raised may be selectively set to further enhance effectiveness of the response of the tine harrow to changing land conditions.

摘要： An agricultural tillage sweep providing good soil action without ridges in the soil surface at both high and low speed operation in different soil conditions. Wings extending outwardly and rearwardly from a leading nose portion include non-flat soil contacting surfaces defining opposed outwardly and upwardly directed surfaces converging in the forward direction. The surfaces, which can be concave upwardly and outwardly, define soil throwing action that progressively increase in the rearward direction. A shallow sweep leading area provides greater upward soil lift and lesser outward soil throw compared to trailing areas. At high speeds, the leading area provides vertical lift and substantial outward throw of soil, and at lower speeds the progressive action surfaces provide additional outward throw of soil to facilitate necessary soil mixing action.
摘要翻译：在不同的土壤条件下，在高低速操作下，农耕耕作提供了良好的土壤作用，在土壤表面没有脊。从前端部分向外和向后延伸的翼片包括非平坦的土壤接触表面，其限定向前方向收敛的相对的向外和向上的表面。可以向上和向外凹入的表面限定了在向后方向上逐渐增加的土壤抛出动作。与俯视区域相比，较浅的扫掠引导区域提供更大的向上的土壤提升和较小的向外的土壤侵蚀。在高速下，领先区域提供垂直升降和大量向外的土壤，而在较低速度下，渐进动作表面提供额外的向外投掷的土壤，以促进必要的土壤混合作用。

摘要： A harrowing device for harrowing a ground surface includes a haulable frame. A plurality of blade holders are secured to the frame, and extend downward from the frame. The blade holder has a cavity, a pair of holes, a pair of inclined interior face in the cavity. The inclined interior faces are arranged so as to become close to each other the further away from the holes. A plurality of blades are fitted to the blade holder, each blade having a shank inserted into the cavity and a blade portion for harrowing the ground. The shank has a pair of holes corresponding to the holes of the blade holder, and a protrusion for contacting the inclined interior faces. A pin is inserted into the holes of the blade holder and the shank to pivotably support the blade.

摘要： The invention is designed primarily for use with resilient tine components which include a pair of resilient spring coils having an attaching U extending between adjacent ends and a resilient tine extending from the outer end of each of the resilient coils substantially perpendicular to the longitudinal axis thereof. These often wear and the most expensive replacement cost is the resilient spring coils. The present invention overcomes these disadvantages by provided a sleeve which engages over the worn ends of the tines and is secured thereto and which has a replacement tine portion secured within the other end of the tubes and extending axially therefrom thus returning the tines to their original length. The sleeves can be secured to the worn ends of the tines either by welding, set screws or other means.
摘要翻译：本发明主要用于弹性齿组件，其包括一对具有在相邻端部之间延伸的附接U的弹性弹簧线圈，以及从每个弹性线圈的外端基本垂直于其纵向轴线延伸的弹性齿。这些经常磨损，最昂贵的更换成本是弹性弹簧圈。本发明克服了这些缺点，即通过提供一个套筒，该套筒接合尖端的磨损端并被固定在其上，并且具有固定在管的另一端内并从其轴向延伸的替换齿部，从而将尖齿返回到其原始长度。袖子可以通过焊接，固定螺丝或其他方式固定在尖齿的磨损端。
