The accessory (ZR) can be attached to the roller to reduce the size of at least one opening.

Description

[0001] The invention relates to accessories for construction machinery such as, in particular, wheel loaders, tractors, Bobcats, skid steer loaders, telescopic loaders or mini excavators.

[0002] From EP 4 263 954 A1 and DE 10 064 149 A1 (whose disclosure is incorporated in full into the present application), so-called screening buckets are known, which can, for example, be attached to an excavator and serve to crush and / or screen construction material. The known screening buckets contain two or more rotatable rollers arranged parallel to each other, on which radially extending discs with teeth are arranged. Between the rollers / discs are openings through which construction material of a desired maximum particle size is allowed to pass.

[0003] Furthermore, it is known to use the bucket of an excavator for mixing concrete.

[0004] Based on this prior art, the object of the present invention was to provide means for improving the functionality of a construction machine. This object is achieved by an accessory according to claim 1. Advantageous embodiments are contained in the dependent claims.

[0005] According to a first aspect, the invention relates to an accessory for a construction machine, wherein the construction machine has a bucket for building material to be crushed and / or sieved, and the wall of the bucket includes at least one rotatable roller along which one or more openings for building material of a suitable size are provided. The accessory is characterized in that it can be attached to the roller to reduce the size of at least one opening.

[0006] An example of this construction machine is the screening bucket mentioned earlier. Due to their design, these screening buckets allow construction material up to a certain solid particle size to pass through. With the described accessory, it is easily possible to reduce the size of the openings in the bucket and thus decrease the maximum particle size of the material that can pass through.

[0007] Preferably, accessories of different sizes can be used to adjust the particle sizes that pass through.

[0008] The specific design of the accessory can take various forms. In particular, it can be designed as a ring that can be reversibly opened and closed at least at one point. Such a ring can then be easily placed around a rotating drum to reduce the opening formed there.

[0009] The accessory can, in particular, have at least one joint (preferably several joints). This allows it to change its shape and, for example, to be opened so that it can be easily placed around a rotating roller. In the simplest case, the joint can be formed by a cut in the material of the accessory.

[0010] To prevent the ring-shaped accessory from detaching itself from the rotating drum, the closed position must be securely locked. This can be achieved, for example, with a snap-lock mechanism where the ends of the accessory lock together or interlock.

[0011] To facilitate the opening and closing of a ring-shaped accessory, it may have recesses into which a suitable tool can engage. For example, holes may be provided for the insertion of needle-nose pliers.

[0012] According to a second aspect, the invention relates to an accessory for a construction machine which has a shovel for mixing concrete, wherein a water connection is provided for supplying water during a mixing process in the shovel.

[0013] The water connection can be designed specifically for connecting a hose (preferably using a standard adapter). This water connection ensures a virtually automatic water supply during the mixing process, eliminating the need for the user to manually add water.

[0014] According to further training, the accessory can include a distribution pipe connected to the water supply, which serves to distribute the water within the bucket. The distribution pipe can, for example, run along the bucket and have several outlet holes.

[0015] The invention is explained in more detail below with reference to exemplary embodiments and the accompanying figures. These figures show: Fig. 1 a top view of a ring-shaped accessory according to the first aspect of the invention in the open state; Fig. 2 the accessory of Fig. 1 shortly before closing; Fig. 3 the accessory of Fig. 1 in the closed state; Fig. 4 the water connection of an accessory according to the second aspect of the invention; and Fig. 5 that to the water connection of Fig. 4 connected distribution pipes.

[0016] The Fig. Figures 1 to 3 show an embodiment of an accessory ZR according to the first aspect of the invention, which can serve as a reducer to reduce the spaces in a sieve bucket (e.g. according to EP 4 263 954 A1 or DE 10 064 149 A1).

[0017] The accessory ZR, for example, is made of plastic and has the basic shape of a ring with a rectangular cross-section. The ring is cut at one point, so that it resembles... Fig. Figure 1 shows that the part can be bent open to fit a rotating roller. Bending is facilitated by incisions that leave a material bridge serving as a hinge G. This simplifies assembly and disassembly.

[0018] Fig. Figure 2 shows the accessory just before the dovetail-shaped "click" fastener engages. Two optional holes above and centered on the notch allow for easy opening and closing with needle-nose pliers. This saves a considerable amount of time during removal and reinstallation.

[0019] By attaching or changing the ZR reducers on a sieve bucket, a user can adjust the size of the sieved material by several millimeters in grain size.

[0020] Fig. Figure 4 shows a water connection on a concrete mixing bucket as an accessory.

[0021] Shown is a 1 / 2" water connection for watering the shovel, but a 3 / 4" or any other size is also possible. The connection leads into the Fig. Five clearly visible distribution pipes, each with outlet holes at the bottom. This allows water to be added simultaneously while filling the bucket – for example, with concrete. The worker has one hand free, and the water is evenly distributed, simplifying further mixing within the bucket.

[0022] The concrete mixing shovels described above are described as follows in the context of marketing: "Discover our robust concrete mixing buckets, distinguished by their versatility. Whether you're working with wheel loaders, tractors, Bobcats, skid steer loaders, telehandlers, or mini excavators, our buckets are the ideal solution for your needs. We offer them in six different sizes, from 200 to 500 liters, making them an indispensable tool for every landscaper, civil engineer, and homeowner."

[0023] A particular highlight is our innovative screw adapter system (available at an additional cost), which offers maximum flexibility in adapting the buckets to your machines, whether wheel loaders or excavators.
