Embodiment Construction

[0078] The following instructions describe techniques for controlling attachments for bulk material handling systems. In the description that follows, a great deal of specific detail (such as logic tools, opcodes, devices used to specify operands; source partitioning / sharing / duplication tools, types and interrelationships of system components, and logic partitioning / integration choices) is For a more complete understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, control structures, gate level circuits and entire software instruction sequences have not been shown in detail in order to obscure the invention. Those of ordinary skill in the art will be able to implement the appropriate function from this description without undue experimentation.

[0079] The terms "one embodiment", "an embodiment", "example embodiment" and the like in the specific...

Abstract

The preset invention provides a bulk material handling accessory (6) such as a conveyor belt cleaner (80) for use in connection with a bulk material handling system. The bulk material handling accessory includes a main frame (92), a scraping member (210) including an arm (252) and a scraper blade (214) pivotally attached to the main frame, and a damper mechanism (302) coupled at one end to the main frame and at another end to the scraping mechanism. A mounting mechanism (232) is attached to the main frame for providing linear and rotational movement of the main frame and the associated scraping member and damper mechanism. The damper mechanism includes a damper (304) having a piston (354) and a housing (338) having a fluid chamber (340). The viscosity of the fluid within the fluid chamber is selectively changeable to change the damping characteristics of the damper mechanism to accommodate changes in operating conditions.

Description

[0001] related application [0002] This application claims the benefit of US Provisional Application No. 60 / 824103 (filed August 31, 2006) and US Provisional Application No. 60 / 885084 (filed January 16, 2007). Background technique [0003] Bulk material handling units are used for the storage and movement of bulk materials such as grain, sand, gravel, coal, etc. Bulk material handling plants include primary plants as well as secondary or accessory plants. The main devices include conveyors, conveyor transfer points, transfer chutes, material boxes, silos, hoppers, related structures, etc. Attachments include conveyor belt cleaners, air cannons, industrial vibrators, belt tracking devices and more which are used in combination with the main bulk material handling unit. For example, ancillary devices such as air cannons and industrial vibrators are used in combination with primary devices such as transfer points, transfer chutes, bins, bins and hoppers to facilitate and contr...
