A dollie assembly for a vehicle wash includes a center link configured for attachment to a drive mechanism of the vehicle wash and having a throughhole with a first bushing extending therethrough along an axis between opposite ends with cylindrical bearing surfaces on opposite sides of the center link. A tire pushing roller is disposed on each of the bearing surfaces for rotation about the axis. A pair of track rollers are supported for rotation about the axis. The track rollers are disposed on an opposite side of the pair of tire pushing rollers from one another such that the pair of tire pushing rollers are between the pair of track rollers. The pair of track rollers are rotatable about the axis independently from pair of tire pushing rollers.

A system comprises a track surface and includes a plurality of motors. The system may further include a plurality of chains. Each chain may be coupled to a motor and may be disposed along a length of the track surface. A plurality of pushers may further be included, with each pusher coupled to a chain of the plurality of chains. In some examples, a controller may be coupled to the plurality of motors.

An automated food grade conveyor, placement and feeder device and system for singulating and placing rolls, egg, meat, or protein patties, and/or cheese and other foodstuffs to assemble and prepare a sandwich, the system being made of food grade materials that are easily cleanable and being made compact and on wheels which results in a system that significantly reduces time, labor, and waste while increasing productivity, quality and freshness; it includes bulk feeding specific food items through a food grade centrifugal feed system, placing the food items with a chain driven pick and place device, transferring food items to separate servo driven trains, automatically placing of a food pattie onto a sliced bun, wrapping of a completed sandwich, and placing the sandwich on a tray, box or container.

The present invention discloses an embedded scraper rotation angle detection device for a scraper conveyor and a detection method. The detection device includes two extensible detection devices, two signal detection units and a remote processing unit. The two extensible detection devices and the two signal detection units are disposed at two ends of a scraper respectively. The signal detection units detect movement displacements of the extensible detection devices in real time and send out signals through wireless transmission modules, the wireless transmission modules and a wireless receiving module are used for data transmission, and a signal display processing module is used to calculate a rotation angle value of the scraper in real time, output and display the rotation angle value simultaneously, compare the rotation angle value measured in real time with a set safety threshold, and send out an alarm indication when the rotation angle value exceeds the safety threshold.

The disclosure relates to a driver for scraper chain conveyors, which has a central portion having a chain link receptacle for attaching the driver to chain links of a conveyor chain, wherein scraper wings adjoin both sides of the central portion and each scraper wing has a web portion and an end portion that is widened with respect to the web portion, wherein, on the underside of the web portion, a wear plate is provided, which covers the web portion in the direction of the end portion starting from a step on the underside of the central portion.

A link for a conveyor chain includes a first portion and a second portion laterally spaced apart from the first portion. The first portion includes a first sprocket-engaging pin, and the second portion includes a second sprocket-engaging pin. The first sprocket-engaging pin and the second sprocket-engaging pin protrude laterally away from one another. The first sprocket-engaging pin and the second sprocket-engaging pin may each have an oblong cross-section. At least one retainer can secure a connecting pin against movement relative to at least one of the first portion and the second portion, and each retainer can be positioned substantially within one of the first portion and the second portion.

An apparatus for removing lightweight debris from a debris-contaminated stream of heavier material. The apparatus includes an enclosed chamber having a material inlet, a chute having a free portion through which the stream can freely fall due to gravity, and a material outlet positioned below the chute. A material stream flows into the chamber via the inlet and then a portion of the stream falls through the free portion and exits the chamber via the outlet. An airflow pathway guides airflows into the chamber via an airflow inlet and out of the chamber via an airflow outlet. An airflow flowing through the airflow pathway that separates a first portion of the debris-contaminated stream from a heavier portion of the debris-contaminated stream. The airflow then carries the first portion out of the chamber via the airflow outlet.
