Definitions

  • the invention relates to a screening machine with two movement systems which execute circular vibrations by at least one eccentric shaft, from separate frames or two side walls with cross members fixed parallel and at regular intervals between the frames or side walls of each system, the cross members located in a screen plane of the two systems alternating with one another arranged and driven by the systems so that the elastic screen covering fields located between the cross members and attached to them are alternately stretched and compressed.
  • the object of the invention is a screening machine of the beginning to create mentioned type, which is of simple construction and has small external dimensions.
  • Such a screening machine does not require a basic frame, so that it is structurally much simpler. It is therefore cheaper to manufacture and, due to the lack of a base frame, its external dimensions are smaller.
  • the vibrations generated by the eccentric shaft or shafts do not have to be intercepted by a basic frame, which previously had to destroy energies. Rather, the vibrational energy is completely consumed by the movement systems, so that less energy is required to sieve materials.
  • Such a construction also shows less wear, since the outer, particularly stressed bearings of the eccentric shaft are missing.
  • a particularly secure storage and simple construction is created when a first of the two movement systems is resiliently mounted on the second movement system and the second movement system is supported resiliently on the ground.
  • eccentric shafts are preferably provided and that both movement systems are stabilized by support springs.
  • two eccentric shafts can be mounted parallel to one another in both movement systems and one of the eccentric shafts can drive the other, in particular via a coupling belt.
  • a second layer of cross beams is attached to the side cheeks above the first screen level, the second screen level Form (screen deck).
  • a screen level or a protective deck be attached to the frame or to the side walls of one of the movement systems above the first screen level.
  • the outer movement system II has two vertical side cheeks (side walls) 1a, 1b, which are formed in the lower area by a box profile 2a, 2b, which is mounted on the substrate via coil springs 3a, 3b.
  • Fastening elements 4a, 4b which hold horizontal cross members 5, protrude on the undersides of the box profiles 2a, 2b.
  • These cross beams are perpendicular to the side walls and transverse to the conveying direction of the material to be screened.
  • on the upper side of the side cheeks 1a, 1b project inward fastening elements 6a, 6b which hold cross members 7, which are parallel to the cross members 5, for a second screen deck arranged above the lower screen deck.
  • a first movement system I is mounted within the side walls 1a, 1b, which in turn has two side walls 3a, 8b which are parallel to the side walls 1a, 1b.
  • cross members 9, 10 are attached to the top and bottom, which are parallel to the cross members of the Movement system II and are at the same height.
  • the lower screen deck 11 thus has approximately 12 to 16 cross members which are alternately attached to one and the other movement system and which carry fields of a flexible screen covering 12 between them.
  • the upper screen deck 13 is designed in the same way.
  • the lower screen deck 11 is laterally delimited by the side cheeks 8a, 8b, a seal 14 made of elastic material being fastened to these cheeks in the lower region.
  • the upper screen deck is delimited by lateral supports 15 which are fastened to the side cheeks 1a, 1b and in turn carry seals 14 on the inside.
  • two eccentric shafts 16, 17, which are mounted fourfold, run transversely to the conveying direction.
  • the eccentric shafts 16, 17 lie in bearings 18a, 18b of the side walls 1a, 1b and in the further inner areas in bearings 19a, 19b of the side walls 8a, 8b.
  • the eccentric shafts 16, 17 are angled twice between the two bearings 18a and 19a and between the two bearings 18b and 19b, so that the axis of the eccentric shaft in the area of the bearings 18a and 18b is coaxial, but the axis in the area of the bearings 18a and 19a are offset parallel to each other. This also applies to the axles in the area of the bearings 18b, 19b. In contrast, the axis of the eccentric shafts in the area of the bearings 19a, 19b is again coaxial.
  • the first eccentric shaft 16 is connected to an electric motor via a drive wheel 20, wherein the drive can take place directly or via a V-belt transmission as well as via a V-belt transmission with a propeller shaft.
  • the second eccentric shaft 17 is driven by the first eccentric shaft 10 via a coupling belt 21.
  • the screening machine can be driven by a single eccentric shaft, the systems then being stabilized by additional support springs.
  • the machine can also have only a single screen deck.
  • a protective deck can be fastened over such a single screen deck. the side cheeks of one of the two movement systems is worn.
