A bucket and a corresponding bucket elevator, the bucket has a bucket wall surrounding a filling and discharge opening and having a rear wall and a front bucket wall, the front bucket wall having a front edge delimiting the filling and discharge opening, and the bucket being connectable to a conveyor device via the rear wall, wherein the ratio between the bucket depth, which corresponds to the horizontal distance between the rear wall and the front edge, and the bucket height, which corresponds to the vertical distance between a bucket low point and the front edge, is greater than 1, preferably greater than 1.3, more preferably greater than 1.5.

An auger conveyor for transferring, from a first location, a mixed material including granular material and unwanted particulate contaminants, to a second location, the granular material substantially free of the unwanted particulate contaminants, comprising a housing in which there is rotatably supported a conveying member in the form of an auger or screw. A portion of the housing is perforated to provide a tubular screen, and the conveying member includes projecting agitation tabs along a length thereof which is coincident with the perforated portion of the housing, to propel the mixed material in the housing towards the screen so as to urge the unwanted particulate contaminants out of the housing leaving the granular material therein for conveyance to the outlet.

The invention relates to a charging unit of a material processing apparatus having a charging hopper, the side walls (22) and rear walls (23) of which can be folded over between a working and a transport position by means of actuators (40, 50). A deflection element is provided, which converts the movement of an actuator during a portion of a movement thereof into a rotational movement of the rear wall or of the side wall and, during a further portion, into a translational movement. As a result of the rotational movement, the rear and side wall can be pivoted between the working and transport position, while by means of the translational movement, the rear and side wall can be connected to each other by means of an appropriate closure (60). By means of the deflection element, a simple, self-securing, and economical structure of the charging hopper is made possible.

A pressing assembly for a conveyor having a first conveyor belt and a second conveyor belt includes a roller support, a linkage coupled to the roller support, a roller rotatably coupled to the linkage, the roller configured to engage the first conveyor belt to press the first conveyor belt toward the second conveyor belt, and a deflector engageable with the first conveyor belt to inhibit contact between the first conveyor belt and the linkage.

A snow conveying assembly for use with a snow making machine includes an impeller for receiving snow from the snow making machine and accelerating the snow; and an ejector tube, which receives the snow from the impeller, further accelerates the snow and discharges the snow from the assembly. The ejector tube contains a venturi throat. Snow from the impeller is conveyed via a snow inlet tube into the ejector tube immediately upstream of a venturi throat and air under pressure is blown into the ejector tube upstream of the venturi throat to further accelerate the snow.

The invention relates to a rock processing machine (10) having a feed hopper (40) and a process unit (20) downstream thereof, wherein a conveying device, in particular a hopper discharge belt (12), is assigned to the feed hopper (40), wherein the feed hopper (40) has a hopper side wall (42), and wherein a side-wall heightening (44) is assigned to the hopper side wall (42), which side wall heightening can be swiveled between a folded-down working position and a folded transport position. In such a rock processing machine, the requirements of occupational safety are effectively taken into account in a simple manner if provision is made that an operating unit (50) having a lever (51) for swiveling the side-wall heightening (44) is assigned to the side-wall heightening (44), wherein a transmission element (52) is used to couple the lever (51) to the side-wall heightening (44), and that the side-wall heightening (44) is secured in the folded-down working position using a movable locking element (60).

A concrete mix separating device for generating cement slurry from a concrete mix includes a bar, which is insertable between adjacent sections of a concrete chute so that a gap is created between the adjacent sections. The bar is sized so that aggregate of a concrete mix, which passes through the concrete chute, is selectively excluded from passing through the gap. Cement slurry, which is substantially free of aggregate, is generated from the concrete mix and passes through the gap. A funnel is attached to the bar so that the funnel is positioned below the gap upon insertion of the bar between the adjacent sections of the concrete chute. The funnel directs the cement slurry into a receptacle, such as a bucket or a wheelbarrow, which is positioned below the funnel.

In accordance with the present invention, there is provided a conveyor skirt system, the system comprising: a support member; a series of skirting panels releasably fixed to the support member; a rail assembly positioned outside the conveyor, extending in a direction substantially parallel to the direction of the conveyor; and a trolley assembly mounted on the rail assembly, the trolley assembly being adapted to engage and support one or more of the skirting panels.

An enclosed belt conveyor system has a rail track (1) and spaced apart carriages (35) that run on wheels (40) supported by the trail track. A continuous carry belt (10) is supported by the carriages (35) and has an enclosed configuration where the carry belt (10) encloses a bulk material for transport by the system. One or more belt guides (45) are positioned along the rail track (1) and engage the continuous carry belt to maintain it in its enclosed configuration.

A sorting device for packages includes a fifth wheel mounted on a support structure and rotatable around a vertical axis; a conveyor belt mounted on the fifth wheel and able to rotate therewith about the vertical axis; and at least one sliding surface placed below the plane of the conveyor belt, to close the openings which, during the rotation of the fifth wheel and of the conveyor belt around the vertical axis, are created between the sorting device and the conveyor belts adjacent to it.
