Definitions

  • the invention relates to a cleaning device with a Opened, air-flowed sieve, with one on the Air inlet side of the sieve arranged brush that in the Bristles penetrating openings of the sieve.
  • a similar screening device is in EP 985439 A. suggested.
  • a rotating sieve i.e. on the Outlet side, its air inlet openings are penetrating, rotating brushes arranged.
  • the brushes are in place in the effective range of one on the air inlet side of the sieve arranged suction device.
  • the suction device work against the direction of the airflow, making it relatively high Suction powers are required.
  • DE 453597 A describes a cleaning device for a sieve described, with the roller-shaped brushes on the entry side of the sieve are arranged. On the exit side is the Brushes opposite one with sector-shaped cutouts provided unbroken plate arranged. This is supposed to that are achieved by brushing out the sieve impurities pressed out due to the through the plate achieved air flow interruption fall. Here is as disadvantageous to see that the falling impurities can get into the airflow below the plates, so that the filter effect achieved is inadequate.
  • the problem underlying the invention is seen in an improved cleaning device for a sieve to provide.
  • the brush has bristles that go into the Openings of the sieve penetrate - they usually also penetrate - and push contaminants out of the openings.
  • the contaminants are on the outlet side of the Siebs by means of a suction device, in its effectiveness and Extraction area, the brush is located, vacuumed and removed.
  • the suction device leads the impurities that have passed through the sieve are safe and with high efficiency, so that damage downstream the sieve of arranged machine components (cooler, engine, etc.) is not to be feared. This way you get one simply constructed cleaning device with high filter effect and low power requirements.
  • the strainer relative to the brush and the suction device move.
  • This movement can be circular (by rotating the Sieve) or linear (by moving the sieve). It is also conceivable to arrange the sieve stationary and the brush and the suction device over the surface of the sieve move.
  • the second suction device With respect to the direction of movement of the sieve downstream side of the brush. Consequently becomes a surface area of the screen from the brush edited and shortly thereafter falls within the sphere of influence of second suction device.
  • the impurities are thus through the action of the brush from the surface of the sieve loosened or loosened and can be extracted more easily.
  • the suction device or suction devices can not only pick up contaminants detached from the sieve by the brush, but also contaminants directly from the surface of the Vacuum sieve.
  • the brush be rotatable and / or is pivotally mounted. This can be different in succession Areas of the brush come into contact with the sieve. Because of the resulting even wear ensures a long service life of the brush. A panning the brush allows successively different (radial) Areas of the sieve with a relatively small brush too to edit. The suction device is also moved so that the brush remains in its effective range.
  • the brush can be rotated without a separate drive Friction of the bristles of the brush on the surface of itself relative to the brush moving - especially rotating - sieve be achieved. But it is also conceivable to have a drive for To provide rotation and / or pivoting of the brush around an axis.
  • the cleaning device according to the invention is suitable especially for agricultural (harvesting) machines, at which have relatively large amounts of impurities. she allows an efficient cleaning of the sieve.
  • a harvesting machine 10 shown in FIG. 1 in the manner of a self-propelled forage harvester is built on a chassis 12 carried on by front and rear wheels 14 and 16 becomes.
  • the harvesting machine 10 is operated by a Driver's cab 18, from which a crop receiving device 20 is visible.
  • goods picked up from the ground e.g. B. corn, grass or the like is fed to a chopper drum 22, which it in small Chops pieces and gives it to a conveyor 24.
  • the Well the harvesting machine 10 leaves for a vehicle traveling alongside Trailer over a rotating discharge chute 26.
  • a suction opening 30 is provided through which a fan (see Figure 2) cooling air for the drive motor and other units of the harvesting machine 10 sucks.
  • FIG. 2 shows a side view of the cooling device of the Harvester 10. It has a propeller-like fan 34 on, which rotates about an axis 33 and through the suction opening 30 ( Figure 1) sucks in air.
  • the air drawn in flows in the direction arrows 56 through a sieve 44 provided with openings 44 and then reaches a downstream of the fan 34 Cooler 32.
  • the cooler 32 is by not shown Coolant lines with the drive motor of the harvesting machine 10 and / or other units connected.
  • the cooler 32 heated air is then returned to the through suitable openings Environment derived. It is conceivable that the fan 34 downstream of the Arrange cooler 32 so that the air coming from the screen 44 Air flows through the cooler 32, then reaches the fan 34 where it can be guided past the engine and then the Harvester 10 leaves.
  • the job of the sieve 36 is to remove unwanted contaminants can arise in large quantities during harvesting, from Keep cooler 32 away.
  • the screen 36 is therefore relative provided small openings 44 which are the largest contaminants hold.
  • Another filter is conceivable downstream of the sieve 36 with narrower pores.
  • the sieve 36 is circular and rotates about an axis 42 which is coaxial with the axis 33 of the fan 34 runs. It is also conceivable that the axes 42, 33 are not to be arranged coaxially, but laterally offset. They run in but generally at least essentially parallel to each other.
  • a cleaning device is provided three, one above the other, independently of each other common axis 52 includes rotatable brushes 46, 48, 50.
  • the Axis 52 extends radially to screen 36. Brushes 46, 48, 50 are arranged on the air inlet side 38 of the screen 36 and have bristles that define openings 44 of sieve 36 penetrate. In this way, impurities from the Openings 44 pushed through.
  • On the air outlet side 40 of the A suction device 54 is arranged in the sieve 36.
  • the brushes 46, 48, 50 are within the sphere of activity of Suction device 54, so that the latter from the brushes 46, 48, 50 impurities pushed through the openings 44 picks up and dissipates.
  • the suction device 54 can in known way with an exhaust ejector - or with a any other device for generating a (sub) Pressure that is less than that at the location of the suction device 54 prevailing pressure is - be connected.
  • Brushes 46, 48, 50 rotate through the friction on the screen 36 about the axis 52, so that no separate drive is required.
  • the suction device 54 shows one about the total height of the brushes 46, 48, 50 extending suction opening.
  • Suction device 58 Based on the top view of FIG Cooling device can be seen on the side next to the brushes 46, 48, 50 a second on the inlet side of the sieve 36 Suction device 58 is arranged. It is - like that Suction device 54 - with a device for generating Vacuum connected. The second suction device 58 is also with an over the entire height of the brushes 46, 48, 50 extending suction opening. The second Suction device 58 sucks through the brushes 46, 48, 50 detached from the inlet side surface of the screen 36 and / or loosened impurities. In particular, the second suction device 58 removes the impurities from the brushes 46, 48, 50 and / or directly from the surface of the screen 36 suck off. The direction of rotation of the screen 36 is such that its Surface first on brushes 46, 48, 50 and immediately then guided past the second cleaning device 58 becomes.
