PIVOTING RATCHET TOE BOARD

An adjustable toe board， an adjustable toe board assembly， kit and sawmill comprising the adjustable toe board are provided. The toe board comprises a baseplate having a first end， an opposed second end， and a rod extending away from the baseplate. The toe board includes a support bar pivotably coupled to the baseplate proximate the first end， spaced apart from the rod， and extending towards the second end， the support bar being configured to support a log. The toe board also includes a ratcheting arm pivotably coupled to the support bar， the ratcheting arm having a plurality of spaced-apart teeth defining notches adapted and positioned to selectively engage with the rod， wherein selective engagement of the teeth with the rod enables pivotal adjustment and releasable locking of the support bar relative to the baseplate during operation.

本发明提供了一种可调式挡料板（adjustable toe board）、可调式挡料板组件、套件以及配备该可调式挡料板的锯木装置。该挡料板包括基板，基板具有第一端、相对的第二端，以及自基板向外延伸的杆件。该挡料板还设有支撑杆，该支撑杆可枢转地连接至靠近第一端的基板，与杆件间隔布置并朝向第二端延伸，用于支撑原木（log）。该挡料板还包括棘轮臂（ratcheting arm），该棘轮臂可枢转地连接至支撑杆，其上设有多个间隔分布的齿，这些齿形成适配且定位为可与杆件选择性啮合的槽口；通过使齿与杆件选择性啮合，即可在作业过程中实现支撑杆相对于基板的枢转调节与可释放锁定。
