摘要： Crop severing and gathering structure is pivotally connected to the forward end of a cotton row unit housing adjacent a row receiving area. A cutter severs the lower portion of cotton plants offset from the row receiving area of the row unit. A conveyer includes a pair of opposed belts with gripping features which embrace the lower portions of the stems of the cotton plants and move the severed plants in a generally upright position into the row of standing plants that is entering the row receiving area. The severed cotton plants intertwine with the standing row at the front of the housing as the conveyor moves the plants against one side of the row. The standing row with intertwined plants enters the row receiving area, and tandem picking drums located on the same side of the row as the severing and gathering structure remove cotton from both the standing row and the severed plants. The opposed belts have surfaces which enhance the gripping and conveying of the severed plants, and rotating brushes above the cutters help gather and hold the plants in the upright position for cutting. The pivotal connection allows the severing and gathering structure to be adjusted to the desired lateral position for a given plant spacing and to be lifted out of the way for convenient access to areas in and near the housing, including access to the row unit door structure. Plant gatherers at the leading end of the severing and gathering structure can be adjusted for alignment with the forward direction when the lateral position of the structure is adjusted for different plant spacings.

摘要翻译： 作物切断收集结构枢转地连接到邻近行接收区域的棉排单元壳体的前端。 切割器切割从行单元的行接收区域偏移的棉花植物的下部。 输送机包括一对具有夹持特征的相对的带，其包围棉花植物的茎的下部，并将切断的植物在大致直立的位置移动到正在进入行接收区域的直立植物的行中。 当输送机将植物移动到该行的一侧时，切断的棉花植物与在壳体前部的直立列交织在一起。 连线植物的立柱进入行接收区域，与排列和收集结构位于同一侧的串联采摘鼓从直立排和切断的植物中移除棉花。 相对的带具有增强切割植物的夹持和输送的表面，并且切割器上方的旋转刷帮助收集和保持植物在直立位置进行切割。 枢转连接允许切断和收集结构在给定的工厂间距处被调节到期望的横向位置，并且被提升到方便地进入壳体内和附近的区域，包括进入行单元门结构的区域。 当结构的横向位置根据不同的植物间距进行调整时，可以调整切割收集结构前端的植物采集器与正向对齐。

摘要： A wheelchair safety lock with a safety handle that is positioned such that the user of the wheelchair cannot enter or exit the wheelchair without moving the safety handle out of the way. When the safety handle is moved out of the way, the brake of the wheelchair is engaged against the wheels of the wheelchair. In order to operate the wheelchair, the safety handle is moved back into position after the user is seated. The safety handle extends in front of the user above the users lap when the user. is seated in the wheelchair. Therefore, the user cannot exit the wheelchair unless the safety handle is moved, thereby engaging the brake. Similarly, if the safety handle has been moved such that the brake is disengaged, the user can not enter the wheel chair because the safety handle is blocking the entrance. The safety handle must be moved in order to enter the wheelchair, thereby engaging the brake. The safety handle is also useful for the user to hold when declining a steep incline.

摘要翻译： 具有安全手柄的轮椅安全锁定位，使得轮椅的使用者在不将安全手柄移开的情况下不能进入或离开轮椅。 当安全把手移开时，轮椅的制动器与轮椅的车轮接合。 为了操作轮椅，安全把手在使用者就座后移回到位。 使用者在安全手柄的前面延伸到用户圈的上方。 坐在轮椅上。 因此，除非安全把手被移动，否则用户不能离开轮椅，从而接合制动器。 类似地，如果已经移动了安全手柄使得制动器脱离，则用户不能进入轮椅，因为安全手柄阻塞入口。 必须移动安全手柄才能进入轮椅，从而接合制动器。 当倾斜陡坡时，安全手柄对于使用者来说也是有用的。
