Definitions

  • the present invention relates to a closing device for a hose outlet of a transport device for transporting bulk goods and a transport device with such a closing device.
  • Transport devices for transporting bulk material are used on many construction sites and are used to supply construction sites with loose building materials or building materials.
  • the transport devices are used for transporting concrete, gravel, sand or similar building materials. If the bulk material to be transported is concrete, such transport devices are also referred to as concrete buckets or concrete silos.
  • Such known transport devices include a container for receiving the bulk material, which is provided with an outlet opening for the bulk material in the lower container area.
  • a closure device communicates with the outlet opening of the container. With the closing device, the exit of the bulk material from the container can be controlled.
  • the closing device is followed by a bulk material guide unit, with which bulk material emerging from the closing device can be guided to a point at a distance from the closing device.
  • the bulk goods guide unit can be designed as a hose.
  • transport devices usually have devices that allow the transport device to be lifted using a crane or the like.
  • the technical problem on which the invention is based is to provide an alternative transport device with which it is possible to easily control the discharge of bulk material.
  • a closing device for a hose outlet of a transport device for transporting bulk material such as concrete, gravel, sand or similar building materials comprises at least two clamping surfaces.
  • the clamping surfaces can be moved towards and away from one another and are designed to compress the hose outlet, which is at least partially elastically deformable, between them in such a way that a cross-sectional area of the hose outlet is reduced or reduced to zero.
  • the flow of bulk material through the hose outlet can be controlled.
  • the invention is therefore based on the idea of compressing the at least partially elastically deformable hose outlet of a closing device of a transport device from the outside, so that the actual free cross-sectional area of the hose outlet for the passage of the bulk material is reduced compared to the maximum free cross-sectional area or even reduced to zero.
  • a closure device is used to control the amount of bulk material discharged from a transport device, which does not control the discharge of bulk material by a closure device arranged above the hose outlet, but controls the discharge of bulk material by squeezing or clamping the hose outlet.
  • the compression preferably takes place variably, so that there is not only an open and a closed position, but positions in between can also be assumed.
  • the closing device can assume the operating positions “open” and “closed”.
  • the "open” operating position corresponds to a position in which the hose outlet is not compressed at all by the clamping surfaces.
  • the “closed” operating position corresponds to a position in which the hose outlet is compressed in such a way that (substantially) no bulk material can flow through the compressed area of the hose outlet.
  • the closing device can preferably assume any operating position between the "open” and “closed” operating position, in which the flow of bulk material through the hose outlet is not completely prevented, but in which the cross-sectional area of the hose outlet available for the bulk material to flow through is larger than the "open” operating position is reduced. As a result, the amount of bulk material discharged can be adjusted.
  • the hose outlet, in which the bulk material is guided, is compressed from the outside with the clamping surfaces. Accordingly, the clamping surfaces of a closing device according to the invention do not come into direct contact with the bulk material. This enables maintenance-friendly control of the bulk material outlet. In addition, such a closure device according to the invention can be produced inexpensively.
  • At least one of the at least two clamping surfaces is an outwardly curved, ie convex, surface, for example the outer surface of a piece of pipe.
  • Damage to the hose outlet in the clamping area can be reliably prevented by the outwardly curved surface.
  • the use of the outer surface of a piece of pipe represents a simple embodiment.
  • Both of the two clamping surfaces can be an outwardly curved surface.
  • only one clamping surface can be an outwardly curved surface.
  • the other clamping surface can be designed, for example, as a flat or inwardly curved outer surface.
  • At least one of the at least two clamping surfaces is a flat surface.
  • Such an embodiment represents a further structurally simple embodiment, through which the hose outlet can be stressed in a manner that is gentle on the material when it is compressed.
  • one of the at least two clamping surfaces is immovable.
  • This embodiment represents a simple design, because the non-movable clamping surface can be made fixed to the closure device and does not require, for example, a rotatable bearing.
  • the closure device has a first closure part and a second closure part.
  • the first closure part is rotatably mounted and comprises a first clamping surface of the at least two clamping surfaces and a first toothed area.
  • the second closure part is rotatably mounted and includes a second clamping surface of the at least two clamping surfaces and a second toothed area.
  • the first and second closure parts are coupled to one another via the toothed areas in such a way that when the first closure part rotates, the second closure part rotates in the opposite direction.
  • Such an embodiment comprises only a few components. Due to the toothed areas, an additional component for the coupling of the first and second closure part can be dispensed with. This allows a compact design to be implemented.
  • the closure device has a first closure part and a second closure part.
  • the two closure parts are rotatably mounted about a common axis of rotation and each have one of the at least two clamping surfaces.
  • the closing device has an articulated arm with two arm members connected to one another via a rotary joint. One arm member is rotatably connected to the first closure part and the other arm member is connected to the second closure part such that when the rotary joint is displaced, the first closure part and the second closure part rotate in opposite directions.
  • the two closure parts are mounted on a common axis of rotation.
  • a closing device can be implemented in a very compact and space-saving manner in the area of the axis of rotation.
  • the locking device includes a lever for moving the clamping surfaces toward and away from each other.
  • one of the two closure parts or the swivel joint of the articulated arm can be moved in such a way that the two clamping surfaces of the closure device move towards one another or away from one another.
  • the capping apparatus further includes a rack and pinion drive having a handwheel and a rack for moving toward and away from each other.
  • one of the two closure parts or the swivel joint of the articulated arm can be moved in such a way that the clamping surfaces of the closure device move towards one another or away from one another.
  • the gear wheel can be connected directly to one of the two closure parts or the pivot joint of the articulated arm, or via it a lever arranged in between can be connected to one of the two closure parts or the pivot joint of the articulated arm.
  • the toothed rack runs at least in regions within a protective tube.
  • a protective tube in which the toothed rack at least partially runs or is displaced when opening or closing, ensures that the toothed rack is not soiled by outflowing bulk material, such as concrete spatter.
  • a transport device for transporting bulk material such as concrete, gravel, sand or similar building materials.
  • the transport device comprises a container for receiving the bulk material, which is provided with an outlet opening for the bulk material.
  • the transport device comprises a hose outlet, with which bulk material emerging from the outlet opening can be guided to a point at a distance from the outlet opening and which is designed to be elastically deformable in a clamping area.
  • the transport device comprises a closing device according to the invention. The clamping area of the hose outlet is arranged between the at least two clamping surfaces of the closure device.
  • the hose outlet is designed in such a way that it can be used to guide bulk material emerging from the outlet opening to a point at a distance from the outlet opening.
  • the hose outlet is designed to be elastically deformable in such a way that it can be compressed in this area by the clamping surfaces of the closing device.
  • Hose outlets within the meaning of this disclosure can have any desired cross-sectional shape.
  • the hose outlet outside of the clamping area may not be elastically deformable or may only be elastically deformable in certain areas.
  • hose outlets have in Fastening area with the container or the closure device on a flange or similar fasteners.
  • Hose drains include elastically deformable materials. For example, rubber hoses are used as hose drains.
  • the closure device is connected to the container and/or the hose outlet.
  • the closure device can be designed in such a way that it has a fastening flange or a similar connection area which can be connected to the container in the upper area and to the hose outlet in the lower area.
  • the hose outlet is pushed onto a cylinder piece and fastened to the cylinder piece with a clamp that wraps around the outside.
  • the cylinder piece is, for example, welded or screwed to the closure device.
  • the closing device can also be designed in such a way that it can be connected to the container, preferably on the side of the container above the outlet opening, and the hose outlet can also be connected to the container, preferably in the area of the outlet opening.
  • the hose outlet can be connected to the container, preferably in the area of the outlet opening, and the closing device can be connected not to the container but to the hose outlet.
  • connection options shown here between the container, the closing device and the hose outlet can be designed to be either separable or non-separable.
  • the technical problem on which the invention is based is solved by a method for adjusting the outflow of bulk material such as concrete, gravel, sand or similar building materials from a container that has an outlet opening for the bulk material.
  • the method includes the step of connecting a hose outlet designed to be elastically deformable in a clamping area the container in such a way that bulk material emerging from the outlet opening enters the hose outlet.
  • the method also includes arranging the clamping region of the hose outlet between at least two clamping surfaces which can be moved towards and away from one another.
  • the method also includes pushing the at least two clamping surfaces together in such a way that the hose outlet is compressed by the at least two clamping surfaces in the clamping area. This reduces or prevents bulk material from flowing through the hose outlet in the clamping area.
  • the method also includes adjusting the outflow of bulk material through the hose outlet by moving the at least two clamping surfaces away from one another and towards one another.
