Apparatus for mixing and / or screening the material to be composted. - Anordning for att blanda och / eller sålla komposterbart material.

The invention relates to a self-propelled device for mixing and / or screening compostable material.

Usually, the material to be composted is treated in several different work steps and with different equipment, whereby the compostable material is transported, e.g. by means of a tractor bucket, and the mixing is carried out, e.g. by means of a towed drum device. Such a multi-stage treatment at each stage of composting results in relatively long processing times. In addition, by conventional methods, the screening waste is usually crushed into the composted material, in which case the bark or wood chips used in the composting must be continuously obtained in addition. The object of the present invention is to provide a device which can reduce the work steps and provide a considerable increase in power in composting and, in addition, when using the device according to the invention, it is possible to re-use screening waste (bark / wood chips).

To achieve this object, the device according to the invention is characterized by the things set forth in the characterizing part of claim 1.

The invention will now be described with reference to the accompanying drawing, which is a schematic side view of a self-propelled device according to the invention.

According to the figure, the device according to the invention comprises a frame part 9 provided with a wheel 10, in which a cab part 2 921 85 3 is arranged. An up and down movable butt part 2 and an excavator part 1 are connected to the frame 9 by means of moving the material in front and / or a conveyor 4 extending from the sides to the dozer blade part, which conveys the material to a replaceable rotating drum 5 arranged in the body part 9. Below the drum 5 there is further arranged a longitudinal conveyor 6 viewed either to the right or to the left. In addition, the device is preferably provided with a rear conveyor 8 for removing material backwards in the direction of travel of the device. The direction of travel is indicated by the arrow A in the figure below. The device is arranged to move steplessly at an adjustable speed. As the machine travels, the excavator part 1 can simultaneously bucket the compostable materials in front of the machine into the dozer blade part 2. The conveyor 4 is preferably arranged at an adjustable speed and equipped with a shredder (not shown). When a closed drum (mixing drum) is used in the machine, the mixed materials are optionally removed to the left, right or directly behind the direction of travel of the machine. When using the machine, the screened drum is freely removed to the right or left of the screened material in the direction of travel of the machine, and the screening waste is removed directly to the rear by a rear conveyor 8.

When using the device, the material to be treated is usually subjected to 4-5 turns on a closed drum during composting, whereby when the material to be composted is ready, screening is performed in the last step with a screen drum that can be replaced instead of a closed drum. If necessary, such a mixer or screen drum can be replaced as a complete unit with a drum made according to the needs of the customer or the material to be processed. This drum replacement is completed quickly because replacement drum 3? L · I b 5 is simply raised to replace the removed drum.

The excavator part 1 is preferably arranged to turn in all directions, whereby it is possible to make e.g. additions of additives such as lime or the like to the material to be composted, e.g. by heaping from piles arranged next to the material to be composted.

The machine cab 3 is preferably provided with control elements for the functions of the various parts of the machine so that one operator can take care of all the functions. In addition, the cab of the machine is preferably equipped with an activated carbon filter, which ensures that the operator is not exposed to potentially harmful substances released from the debris into the air.

When using the device, an even more uniform working quality and cleanliness of the composting area are achieved as the material to be composted forms even pits as the device progresses.

Claims (7)
