摘要： An improved disk harrow C-spring with a tapered cross section which reduces the compressive stresses in the inside radius and improves vertical and side-to-side flexibility. The curved portion of the C-spring has a constant cross section at the top and around three-fourths of the bend. At a location on the bend 45 degrees down from the horizontal, the thickness tapers to a location forward of the bearing hanger. The cross section is constant from the end of the taper to the end of the spring. The tapered cross section allows a thicker section to be used on the most highly stressed areas in the upper quadrant of the curved portion of the C-spring. The lower quadrant taper results in uniform stress distribution along the entire C-spring with the maximum compressive stress on the inside radius reduced substantially over a conventional C-spring. In addition, the tapered design provides an increase in both vertical and side-to-side flexibility for improved operation in rocky soil.
摘要翻译： 一种改进的圆盘耙C型弹簧，具有锥形横截面，可减小内径的压缩应力，并提高垂直和侧对侧的灵活性。 C弹簧的弯曲部分在顶部和弯曲部的四分之三处具有恒定的横截面。 在弯曲处的水平位置下降45度的位置，厚度逐渐变细到轴承架的前方位置。 横截面从锥形的端部到弹簧的端部是恒定的。 锥形横截面允许在C弹簧的弯曲部分的上象限中的最高应力区域上使用较厚的部分。 下象限锥形导致沿着整个C形弹簧均匀的应力分布，内径半径上的最大压应力基本上大大降低了传统的C形弹簧。 此外，锥形设计提高了纵向和侧向的灵活性，以改善岩土的运行。

摘要： A cultivator sweep includes a body with a forward point and wings diverging outwardly in the rearward direction. In one embodiment, a row side sweep includes a row side wing angled upwardly from the horizontal at an angle of approximately 27 degrees, and the opposite wing is angled downwardly, to closely match the profile of the ground from the row bed to the row middle. In another embodiment of the invention, a wide sweep extends between the beds of adjacent rows and includes wings with outermost portions bent upwardly at an angle with respect to the horizontal to provide a sweep profile which closely approximates the ground profile between the rows for more uniform depth of penetration, less soil throw and crop root damage, and reduced draft. The sweep configuration, wherein a fore-and-aft extending line connecting a point anywhere on the leading edge of a sweep wing with a corresponding point on the trailing edge of the wing lies at a substantially constant angle relative to a horizontal plane, provides constant soil lift regardless of soil contact point along the leading edge. The sweep configuration therefore provides soil flow characteristics similar to those of a conventional flat sweep.

摘要： A simple, light-weight C-shank standard is mounted on a bracket which is corner clamped to a rig cross tube on a row crop cultivator. A pin inserted through apertures in the bracket maintains the shank in a preselected field-working attitude. The pin can be removed to allow the shank to be pivoted upwardly for maintenance, sweep removal, or residue removal. The shank can be supported in the raised position by the pin when the cultivator configuration is changed for cultivation in lay-by conditions, or for operation in skip row or other special crop configurations. In one embodiment of the invention, the shank is edgebent and selective placement of the pin through one of a plurality of sets of mating holes in the bracket and the upper portion of the shank permits adjustment of the working position of the shank. A mounting slot at the lower end of the one embodiment of the shank provides pitch adjustment for the earthworking tool.

摘要： A multiple rig row crop cultivator with first and second concave disks supported for operation at two different depths from adjacent rigs to provide two-step sizing of residue. The first disk, located ahead of the second disk, operates at a first depth in the soil to slice out the upper portions of roots and direct plant residue to the row middle. The second disk cuts to a depth approximately twice that of the first disk to further cut out root sections and move the root sections and other plant debris to the opposite row middle. After the disks move stalks and roots to the row middles, sweeps with ridging/bedding wings move the mixture of soil, stalks, and roots to the top of the bed to cover the groove made by the disks and preserve the original plant bed.

摘要： The invention provides an apparatus and method for enabling at least a minimum pressure and flow rate of stored NH3 from a storage tank to knives for injection into soil, regardless of ambient temperature. A pressure sensor and control valve monitors the pressure of the NH3 flow. If the sensed pressure drops below a desired minimum, e.g., 0.5 psi, a controller drives the control valve to open and also signals ramping up of a boost pump. The boost pump pumps NH3 from the storage tank to ensure maintenance of a minimum flow rate and pressure of NH3 from the tank to the soil. The pump runs on-demand only as needed, thereby reducing power requirements when the pump is not needed to supplement NH3 tank pressure.

摘要： A chain is connected at its distal end to the pin at the rod end of a cylinder on an implement lift and depth control assembly. An intermediate portion of the chain is trained around a gear which rotates about the axis of the pin connecting the base end of the cylinder to the implement frame. An adjustable length, spring-biased rod is connected to the proximal end of the chain to maintain tension in the chain and operate a single point depth control valve to establish a highly accurate and repeatable depth setting which is dependent directly on cylinder rod extension and therefore less susceptible to looseness in the implement lift system.

摘要： A simplified method of assembling a disk from the ground up by first assembling disk gangs and then connecting the disk gangs together to provide a self-standing front and rear main disk gang pairs. The main frame is assembled over main disk gang pairs after which wheel modules are attached. Disks of different sizes are assembled, utilizing generally identical main frame beams with the same connecting locations, by decreasing the distance between the forward and rear gang pairs and moving the main frame beams outwardly as the desired width of the disk increases.

摘要： A spray system is provided with improved spray control having decreased injection lag, and reducing non-uniformity in injection lag throughout the length of a spray boom. A pump is coupled to spray nozzles installed along the spray boom by manifolds which divide the spray boom into a predetermined number of zones. Each zone has a respective boom manifold, and each boom manifold is coupled through equal length line to the spray nozzles. The size of lines coupling the pump to the boom manifolds varies with position along the spray boom and restricting orifices are used in some of the connecting lines. Application systems constructed according to principles of the present invention respond quicker to changes in pump operating points than conventional systems and variability of injection lag along the length of the spray boom is virtually eliminated with the present invention.
