摘要： An improved blade for a scraper assembly used with the head pulley of a conveyor system. The improved conveyor blade has a metal base adapted to telescopically engage a rectangular plate projecting radially from a support shaft mounted for rotation about a rotary axis parallel to the head pulley axis, the metal base having sheet-like outer walls disposed in spaced parallel relation from a receptacle for the elastomeric body of the blade. The blade has an under surface confronting the head pulley which projects past the plane of the innermost wall of the metallic base and terminates in a tip engaging the belt on the head pulley.

摘要： A conveyor belt scraping apparatus comprises a blade having a blade edge biased against a conveyor belt. The blade is supported at its base and has a web extending from the base to support the blade edge. The web has at least one groove therein substantially parallel to the blade edge to define a tensioning region at the narrowed region of the web, whereby the blade may be biased and tensioned without need for external biasing and tensioning arrangements. Preferably, there are plural grooves in the web. Also preferably, the plural grooves are of different sizes so as to provide a progressive rate to the spring characteristic of the tensioning region of the web. In addition, a groove may have a cushioning material therein so as to provide cushioning of the blade.

摘要： A conveyor belt cleaner is provided having a scraper blade arranged transversely on the lower run of the belt. The scraper blade can have at least one blade or a plurality of blades pivotally connected together. A shaping element having a non-linear configuration adjusts the profile of the scraper blade to match the configuration of the shaping bar. A biasing element connected with the vertical controller biases the scraper blade towards the belt maintaining the scraper blade in contact with the belt. A vertical controller raises and lowers the position of the scraper blade to provide for angular adjustment of the scraper blade relative to the belt.

摘要： A one-piece replacement sleeve is provided for installation on a conveyor belt roller to prolong the roller's wear life. The cylindrical, split sleeve has a central bore to receive the roller and circumferential grooves in the outer surface to receive fastening circlets to fasten the sleeve to the roller. The sleeve has two radial slits oppositely disposed and extending axially along the entire length of the sleeve to facilitate easy installation and replacement of the sleeve. The slits allow the sleeve to be installed on the roller without the need to remove the roller from its journal mountings. The slits also allow the worn sleeve to be quickly and easily removed by cutting or otherwise removing the fastening circlets. Since the sleeve is formed of one piece of material, the sleeve wears concentrically, reducing vibrations in the conveyor belt assembly. The sleeve provides significant improvements over roller discs and two-piece roller sleeves in the prior art.
摘要翻译：提供一体式更换套筒，用于安装在传送带辊上，以延长滚筒的磨损寿命。圆柱形分体式套管具有中心孔，用于接收滚子和外表面中的圆周凹槽，以接收固定圈，将套筒固定到滚子上。套筒具有两个相对地设置并沿套筒的整个长度方向轴向延伸的径向狭缝，以方便安装和更换套筒。狭缝允许套筒安装在辊子上，而不需要从其轴颈安装件移除辊子。狭缝还允许通过切割或以其他方式去除紧固圆圈来快速且容易地去除磨损的套筒。由于套筒由一片材料形成，套筒同心地磨损，减少了输送带组件的振动。在现有技术中，套筒提供了对辊盘和两件式辊套的显着改进。

摘要： An apparatus for scraping conveyor belts having a plurality of resilient scraping blades dependent on each other for lateral support and pivotal stability, but capable of individually flexing away from the belt surface. Each blade is positioned in side-by-side abutting relation across the width of the conveyor belt, and sufficiently thick to prevent blade twisting or turning by providing mutual support for the abutting blade or blades. The blades extend into angled engagement with the belt to shave debris from the belt surface. Each blade is mounted on a single trailing arm which is disposed within a tensioning blade support element to allow independent flexing of the blades away from but not towards the belt surface. The support elements are set in a longitudinal array and mounted for rotation on a shaft positioned transversely and in spaced relation to the belt surface.
摘要翻译：一种用于刮擦输送带的装置，其具有多个相互依靠的弹性刮板，用于横向支撑和枢转稳定性，但是能够单独地偏离带表面。每个叶片跨越传送带的宽度并排定位，并且足够厚以通过为邻接的叶片或叶片提供相互支撑来防止叶片扭转或转动。叶片延伸成与带成角度的接合，以从皮带表面刮去碎屑。每个叶片安装在单个牵引臂上，该牵引臂设置在张紧叶片支撑元件内，以允许叶片从皮带表面独立地偏转而不是朝向皮带表面。支撑元件设置在纵向阵列中，并且安装成用于在横向定位并且与带表面间隔开的轴上旋转。

摘要： A trailing arm scraper assembly for a conveyor belt having an arm extending generally in the direction or normal travel of the belt, and a scraper blade mounted at one end of said trailing arm in a home position having a scraping edge forcibly engaging said belt surface. A blade-mounting block at the end of the arm has a stud element releasably mounting said scraper blade for replacement, and affording pivotal movement of said blade about a blade axis substantially parallel to its scraping edge. The scraper blade has resilient abutments to engage the blade-mounting block to yieldingly resist pivotal movement of said blade away from its home position upon encountering an obstruction on the belt surface as it travels past the blade, and to return said blade to its home position upon travel of the obstruction beyond the blade. The abutments allow greater pivotal movement when obstructions are carried by the belt traveling in a direction reverse to its normal travel. The blade is designed to wear away to provide fresh scraping edges conforming to the contour of the belt. A blade is shown with a uniform width for a set distance from the original scraping edge, and narrowing width beyond the set distance, so that excessive wear is indicated by a narrowing of the swath scraped by the blade.
摘要翻译：一种用于传送带的拖臂刮板组件，其具有大致沿着带的方向或正常行进延伸的臂，以及刮刀，其安装在所述拖臂的一端处于原始位置，该刮刀具有强制地接合所述带表面的刮刃。在臂的端部处的刀片安装块具有可拆卸地安装所述刮刀用于更换的螺柱元件，并且提供所述刀片围绕基本上平行于其刮削刃的刀片轴线的枢转运动。刮刀具有弹性支座以接合刀片安装块，以便在所述刀片行进通过所述刀片时遇到所述带表面上的障碍物并使所述刀片返回到其原始位置时能够抵抗所述刀片远离其原始位置的枢转运动障碍物行进超过刀片。当障碍物沿着与其正常行程相反的方向行进时，该支座允许更大的枢转运动。刀片设计为磨损，以提供符合皮带轮廓的新鲜刮边。显示出具有均匀宽度的刀片与原始刮削边缘的设定距离，并且缩小宽度超过设定距离，使得由刀片刮下的条纹变窄来表示过度磨损。

摘要： A belt scraper for cleaning the conveyor belt on a cylindrical pulley including a plurality of scraping blades having transverse scraping edges at the leading end of the blade side surface which faces the conveyor belt. The side surfaces are tangential to and resiliently against the belt by a transverse rotary shaft parallel to the scraping edge. A separate blade support element connects each blade to the shaft so that the blades extend across the belt width, and includes a torsion element providing an additional point of rotation between the scraping blade and the rotary shaft located transverse to force the blade to pivot away from the belt surface upon impact by an object moving with the belt into engagement with the blade against the scraping edge.
