Definitions

  • the invention relates to a device for processing Kleingut, Erdgut and the like with a rotatably mounted drum-shaped sieve which is drivable via a drive shaft, wherein a drive device for driving the drive shaft is provided and the drive shaft also drives a rotary member of a crushing device.
  • sorting, cleaning and mixing devices for use in industry, the construction industry, horticulture or agriculture, for the treatment of bulk and waste products and land products are known in principle. These devices are offered in accordance with various applications, various embodiments.
  • a wood chipper with a drive motor and a fan-provided wood pulp dryer and a discharge fan is known.
  • a drive motor a diesel engine is provided, which also supplies a chopper downstream drum screen and a downstream discharge fan with energy.
  • the waste heat and the exhaust gas of the diesel engine are fed to the drum screen for drying the wood chips.
  • the accumulating under the drum screen dust is collected by a conveyor belt and passed for later disposal in a container.
  • this device is correspondingly large and thus unsuitable for private use in gardens.
  • the DE 10 2005 013 693 A1 discloses a disc or drum refiner for grinding and cleaning an agglomerated mixed plastic used to make a pulp.
  • garden shredders for crushing plant remains basically known, which arise about in tree and hedge trimming, and larger and more powerful designs in the industrial field.
  • the subsequent sorting, cleaning or mixing or independent filtering of soil material requires, in particular in the field of application in gardens where no devices are used as known in the industrial application, a further device to be provided.
  • the object is achieved in that the screen is attachable to a freely projecting end of the drive shaft. Due to the inventive combination of a crushing device and a screening device advantageously only a single drive device is required, resulting in significant synergy effects. In particular, the manufacturing cost of the inventive combination of screening and crushing device are significantly lower than for two separate Devices. Further, compared to two separate devices, the need for storage space is significantly reduced, as is the weight of the device according to the invention. For use outside of the storage space so only a single device is to be transported, whereby the user saves time and effort during manual transport. Furthermore, it is advantageously possible, with the shredder processed Gargut, eg branches, leaves, etc., then to sort immediately on the drum-shaped sieve.
  • the drum-shaped sieve is attachable to a freely projecting end of the drive shaft, the drum-shaped sieve can be easily connected to the drive shaft - without the aid of tools - if necessary. The removal of the screen as needed can thus be done easily and quickly.
  • This is for example also advantageous if the crushing device is to be used without the drum-shaped sieve, in particular in order to reduce the weight of the device during transport from a storage room or in the storage room.
  • this embodiment is a simple means to switch between drum-shaped screens different screen hole diameter can.
  • an electric motor or an internal combustion engine is provided as a drive device for driving the drive shaft.
  • An electric motor offers the user of the device according to the invention the advantage of simple, substantially maintenance-free handling, without having to supply fuel, while an internal combustion engine can be operated independently of the availability of electric current, and thus independent of location.
  • the engine power is adapted to the output of the two sub-devices consisting of crushing device and drum-shaped screen factory. By operating eg a power button or main switch, the device can be put into its operating state.
  • the motor can be designed with adjustable speed, wherein a control element enables the user to change the power to be supplied as needed.
  • a transmission is provided between an output shaft of the drive device and the drive shaft in order to adapt the rotational speed of the motor to a speed which is appropriate for the two partial devices.
  • a reduction gear is provided between the engine and the drive shaft of the two sub-devices.
  • the field of application of the comminution device comprises, in particular, the supply of thinner branches or perennials, so that a suitable driving force can be applied via the drive shaft arranged after the gearbox; a high speed, however, is by no means required.
  • the drum-shaped sieve is operated at low speeds to achieve efficient sorting of the supplied garden or Erdgutes. With the help of the reduction gear these requirements can thus be met in a simple manner by reducing the speed and the torque required for the two sub-devices is increased.
  • the reduction gear is designed such that it reduces the speed of the drive device to 20 to 60 U / min.
  • the crushing device between the gear and the drum-shaped sieve is arranged, whereby the supply of the plant material in the crushing device from above or is made possible laterally and the filling of the rotating about the horizontally disposed drive screen advantageously and for the user in a convenient way of the , the engine opposite end can be made.
  • the motor thus drives both subdevices via a common drive shaft extending from the motor in a single direction. Compared to an arrangement of the engine between the two sub-devices thus only a single transmission and a simplified shaft bearing is required.
  • the drum-shaped sieve has a preferably full-surface bottom surface with a central passage opening for receiving the drive shaft, wherein the connection between the drive shaft and the bottom surface preferably via a groove / feather key connection is on the one hand opposite to the open side of the drum-shaped screen Side unintentional leakage of the bulk material to be screened prevented and on the other hand the rotating, filled drum imparted the necessary mechanical stability.
  • the drive shaft preferably has a feather key in order to easily transmit the rotational movement to the drum.
  • the drum may have a pin for engagement with a corresponding receptacle in the drive shaft.
  • the rotational element of the comminuting device preferably a milling drum
  • is positively connected preferably via a shaft / hub connection with a key, with the drive shaft rotatably connected.
  • This type of positive connection allows a structurally simple, reliable torque transmission. It has thus surprisingly been found that both sub-devices can be operated at the same speed, and thus no separate transmission must be provided in order to increase or decrease the rotational speed of the rotary element of the crushing device with respect to the rotational speed of the screening device.
  • the drive shaft between the gear and the crushing device, and between the crushing device and the drum-shaped sieve is mounted.
  • the storage of the drive shaft according to the invention in two places at the same time ensures high mechanical stability and smooth running of the device. Due to the weight of the introduced into the sieve bulk material, which may be distributed unevenly over the circumference of the screen in the operating state of the device under these unfavorable conditions transverse forces acting on the drive shaft which are absorbed by the bearings.
  • plant material can be supplied simultaneously to the filling of the drum-shaped sieve of the comminution device, in the comminution of mechanically strong material, such as branches, additional transverse forces acting on the drive shaft, which are uncorrelated to the transverse forces caused by the drum-shaped sieve, are produced.
  • the preferred storage prevents rotation-induced mechanical deformation of the drive shaft and thus increases the life of the device and the maintenance intervals of storage.
  • At least two rotatably mounted rollers are provided. These rollers can engage in a groove along the circumference of the drum-shaped screen as close to the receiving opening and reduce the resulting by the weight of the bulk material torque on the connecting element between the drive shaft and the central passage opening of the sieve.
  • the at least two rollers are preferably arranged around the circumference of the drum-shaped screen to accommodate the vertical forces created by the weight of the screen to a greater extent than the horizontal forces created by rotation and uneven loading.

  • a cleaning brush is provided adjacent to the cylindrical surface of the drum-shaped screen, which extends with its bristles at least partially through the openings of the screen surface into the interior of the screen.
  • the bristles thus clean the surface of the drum-shaped screen of sifted bulk material adhered to the screen surface and remove bulk material sticking out of the holes or adhering the holes to maintain the sifting property.
  • a bristle material is any natural or artificial material with sufficient abrasion resistance and bending stiffness in question, which preferably despite the invention brush function, the surface of the drum-shaped screen not scratched in a manner recognizable to the user.
  • the cleaning brush should be as easy as possible with simple mechanical means such as clamping or quick-clamping devices without the use of tools mountable and replaceable. Further, more than one cleaning brush may be disposed around the surface of the cylindrical screen having the same or different brushing properties. Thus, brushes with bristles of different lengths or bending resistance, or alternatively full-surface plastic or rubber strips or bands, can be used.
  • the drive device, the comminution device and the drum-shaped sieve are mounted on a common, preferably frame-shaped frame.
  • the common frame allows the assembly and operation of the sub-devices on a common drive shaft with the required design-related geometric tolerances.
