Description

The present invention is based on a hose reel with a roll for winding or unwinding a hose, preferably a flat hose, the roll being rotatably mounted about a first axis of rotation on a roll holder of the hose reel.

Hose reels of this type are used, for example, in agriculture for transporting and laying irrigation hoses. The hose reel is usually attached to a tractor. With the hose reel e.g. During the irrigation season, for example, a pressure hose, which is used to connect a water pump to an irrigation machine, is laid on a field and taken up again. For this purpose, 10m to 1000m of hose are usually laid per field.

Hose reels with a cantilever arm through which the hose to be laid is guided are known. However, hose reels of this type have proven to be less practical, for example a hose should be laid on a road or roadside or laterally parallel to the tractor, since in this case the hose is bent or bent by the guidance of the extension arm. Likewise, due to the relatively rigid hose laying direction due to the guidance of the boom arm, increased maneuvering of the tractor is necessary in order to align the boom arm in a suitable manner.

It is therefore the object of the present invention to provide a hose reel which facilitates the laying of hoses to be laid and the retrieval of laid hoses.

This object is achieved by a hose reel with the features of claim 1 and a vehicle with the features of claim 16. The dependent claims relate to advantageous embodiments.

Accordingly, the hose reel has an adjustment mechanism that is set up to adjust the reel holder relative to a support structure of the hose reel that is movably connected to the reel holder. By adjusting the roll holder and thus also the roll relative to the support structure, the hose storage is simplified, for example at the side of roads or streets.

The hose to be wound up or unwound can consist of or have several individual hoses or hose sections connected to one another. The roll holder and / or the support structure can be or have a frame and / or frame.

The adjustment mechanism can have a sliding mechanism, which can be set up to translate the roller holder relative to the support structure. The roll holder can be moved linearly in one or more spatial directions relative to the support structure.

The adjustment mechanism can have a pivot mechanism, which can be set up to pivot the roll holder relative to the support structure about a second axis of rotation. It can be provided that the adjustment mechanism has both a sliding mechanism and a swivel mechanism. It can also be provided that the swivel mechanism can cross the roller holder relative to the support structure about one or more further axes of rotation, for example about a further axis of rotation oriented perpendicular to the second axis of rotation.

The swivel mechanism can have at least one swivel arm which can be connected to the roller holder and the support structure, the roller holder being pivoted relative to the support structure about the second axis of rotation when the swivel arm is swiveled from a zero position.

The swivel mechanism can have at least two swivel arms which can be arranged symmetrically with respect to the second axis of rotation, a center of the roller, the roller holder and / or the support structure. The symmetrical arrangement can result in a uniform distribution of force and torque in the roll holder, the support structure and / or the swivel mechanism, or a uniform load.

The swivel arm can be extended or be or have a telescopic swivel arm. It can be provided that the swivel arm supports or guides the swiveling movement of the roll holder. Alternatively or additionally, the swivel arm can execute the swiveling movement of the roll holder. For example, the swivel arm can be set up to vary its length in response to a control signal, i. H. either retract or extend, whereby the roll holder is pivoted relative to the support structure accordingly.

The first axis of rotation can be arranged essentially horizontally, wherein the second axis of rotation can be arranged essentially perpendicular to the first axis of rotation.

The roll holder can be pivotable between a first position and a second position about the axis of rotation, between the first and a maximum swivel angle can be included in the second position. The maximum pivoting angle can preferably be between 45 ° and 90 °, particularly preferably between 45 ° and 180 °.

The roll can have a hose holder, which can be configured to fix one end of a hose to be wound onto the roll. This makes it easier to wind up the hose, since slippage between the hose and the rotating roller is counteracted.

The hose holder can have a web projecting from a side wall of the roll and spaced parallel to a winding surface of the roll. The perpendicular distance between the winding surface and the web can be smaller than a hose connector and larger than a hose thickness of a hose to be wound. This allows a hose to be wound up to be inserted into the gap between the web and the winding surface. If the roll is now rotated to wind up the hose, the connecting piece of the hose can press against the web or be held by the web, so that the hose is fixed to the roll. It can also be provided that the web, at least in sections, is not arranged parallel to the winding surface, but rather runs obliquely, so that the gap formed by the web and winding surface has a wedge shape. As an alternative or in addition, the hose can thus be or is clamped between the web and the winding surface or can be fixed by a frictional connection. It can be provided that the hose holder has a plurality of webs which are circumferentially spaced apart from one another. Alternatively or additionally, it can be provided that at least one web is arranged on each side wall of the roller. Depending on the number and arrangement of the webs, a comfortable winding of the hose can thus be made possible, since the roll does not first have to be rotated into a specific position in order to make the hose holder accessible.

The hose holder can have at least one U-shaped opening with a width smaller than a hose connector and larger than a hose thickness of a hose to be wound, so that the hose to be wound can be insertable into the U-shaped opening. The U-shaped opening can preferably be arranged on a side wall of the roller. The hose connector can thus be held or fixed by the side wall of the roll and a slippage or a relative movement of the hose can be counteracted during winding. It can be provided that not only one but several or both side walls of the roller have one or more U-shaped openings. The U-shaped openings can be obstructed all around at an angle. Depending on the number and arrangement of the U-shaped openings, a comfortable winding of the hose can thus be made possible, since the roll does not first have to be rotated into a specific position in order to make the hose holder accessible. Alternatively or additionally, the U-shaped opening can also be arranged on the web. The vertical distance between the web and the winding surface can thus also be greater than the hose connector or its cross-section, although it is still possible to fix the hose to the roll. It can be provided that the hose holder has one or more U-shaped openings in the side walls of the roller and one or more webs (possibly with a U-shaped opening).

The hose reel can have a trough connected to the roll holder or the support structure. The trough can preferably be arranged below the roller. The trough can be used, for example, for storing or transporting tools, e.g. serve for connecting the hose.

The hose reel can have at least one motor, which can be set up to rotate the roller about the first axis of rotation and / or to adjust the roller holder relative to the support structure with the adjustment mechanism. The motor can preferably be an electric or hydraulic motor. It can also be provided that the tube passport picture has several motors, of which e.g. a first motor can rotate the roller about the first axis of rotation and a second motor can adjust the roller holder relative to the support structure. Alternatively or additionally, it can be provided that the roller and / or the roller holder are pivoted manually. For this purpose, the hose reel can have suitable manipulations, for example cranks or the like.

The support structure can have a fastening element for connecting the hose reel to a corresponding fastening element. The corresponding fastening element can preferably be a corresponding fastening element of a vehicle. The vehicle can be a utility vehicle, e.g. be a tractor or the like.

Another aspect of the invention relates to a vehicle with at least one corresponding fastening element and at least one hose reel described above, the hose reel being connected to the corresponding fastening element of the vehicle via a fastening element of the support structure. The hose reel is preferably detachably connected to the vehicle.

The vehicle can be a commercial vehicle, for example a tractor, a fire truck or the like. There may be more than one hose reel attached to the vehicle.

The corresponding fastening element can be arranged on a front and / or rear of the vehicle, so that the hose reel can be fastened on a front and / or on a rear of the vehicle. If the vehicle is a tractor, for example, exactly one hose reel can be attached to the front of the tractor in one embodiment. The front of the vehicle can be the side that has a driver's window. The rear of the vehicle can mean the side opposite the front.

The vehicle can have an energy source connected to at least one motor of the hose reel for driving the motor, wherein the motor can be configured to rotate the roller about the first axis of rotation and / or to adjust the roller holder relative to the support structure with the adjustment mechanism. However, it can also be provided that the hose reel alternatively or additionally has the energy source for driving the motor.

The reel holder can be pivotable between a first and a second position, wherein in the first position the reel with at least a first side of the reel can protrude beyond a first side of the vehicle and in the second position the reel with at least one of the first side of the vehicle Roll opposite second side of the roll can withstand a second side of the vehicle opposite the first side of the vehicle. If, for example, the hose reel is attached to the front of the vehicle, the first side of the vehicle can correspond to the left side of the vehicle and the second side of the vehicle can correspond to the right side of the vehicle (in each case relative to the driver's window).
