Definitions

  • the invention relates to a screening device, in particular for loading excavators and wheel loaders for cleaning earth, such as compost, urban waste and household waste.
  • Known earth screening devices are constructed so that a rotatable screening drum is mounted on rollers. Upstream of the screening drum is a loading device consisting of a funnel, scraper floor or conveyor belt. This device conveys the applied gilt into the drum. Since the material to be sieved can be very greasy and sticky, depending on the weather, the material to be sieved often jams at the feed point of the sieve drum, which greatly reduces the performance of the sieve device.
  • a device for separating grain mixtures in which the loading end of a flat elastic screen is attached to a spiral return spring.
  • the discharge end of the screen can be moved back and forth in an oscillating manner, for which purpose projections which protrude downward are provided, on which pins driven on a driven drum engage. From the bottom, the sieve is acted upon obliquely by a fan in the conveying direction of the material to be sieved.
  • a screening device for clogging-free screening in which a tensioning shaft screen bottom is provided.
  • This sieving device works with tensioning and relaxation movements in sieve bottom zones which are arranged one behind the other or next to each other.
  • Stretch-elastic special plastics are used in particular for the sieve bottom.
  • a horizontal overstretching of the screen in the tensioned horizontal position can also be provided.
  • the object of the present invention is therefore to design a screening device of the type mentioned at the outset in such a way that a loading device can be dispensed with, so that there is no jamming of the material to be screened.
  • the design according to the invention enables direct loading of the screening device, so that a separate loading device can be dispensed with.
  • the sieve effect is fully preserved as with a sieve drum, e.g. B. Flying role of the screened material, self-cleaning of the mesh etc.
  • the material to be screened falls directly or through a pre-grate into the screening trough.
  • the sieve bottom of the trough consists of elastic mats, which are perforated and hang in a semicircle in the trough.
  • the sieve plate moves in such a way that the material to be sieved forms a flying roller, once turning to the left and once to the right, depending on whether the sieve plate is raised or lowered. This results in a sieve effect similar to that in a sieve drum. If a sieve drum sieves optimally, the material to be sieved forms a flight role.
  • the screenable material falls through the mat openings on a conveyor belt and is removed.
  • the sieve residues migrate through the inclination of the sieve device to the lower end of the trough and fall out.
  • the screening device can be loaded with very coarse screenings - even without a pre-screen.
  • the mats of the sieve trough can be made very tear-resistant (e.g. nylon inlays or steel cables interwoven and coated with rubber or PVC). They prevent the coarse parts from breaking up the sieve bottom.
  • very coarse screenings it is also possible to use link chains that form a trough spaced apart by strong round bars.
  • the screening device can be designed as a mobile or stationary system. Are particularly suitable for the drive Hydraulic motors and winches as well as diesel or electric motors that are connected to hydraulic units.
  • the sieve device 1 shown in the drawing has a sieve trough 2, a front grate attachment 29, conveyor belt 25, a catch plate 26, compression springs 6, cable deflection rollers 13 and cable articulation points 37 for sieve plate drive 14, clamping bar 9 and clamping bar guide 10, support rollers 8, which guide the sieve plate 3 to the drive 14, a chain arrangement 38 of the sieve plate drive, an electro- or diesel-hydraulic drive 39 for the sieve device 1 and hydraulically adjustable supports 28, cf. 1 to 5.
  • the bottom 3 of the sieve trough 2 consists of elastic, perforated mats 4, which are raised and lowered by a drive 14 and are designed such that the bottom forms a semicircle in the raised position and contains the contents of the loading scoop can.
  • the perforated, elastic mats 4 are connected at one end 18 on the loading side 7 of the sieve trough 2 with the trough edge via a clamping bar 9 ', which rests on the compression springs 6; the other end 18 'of the mats is passed over the support rollers 8 to the drive 14, which raises and lowers the mats 4.
  • the lifting and lowering speed of the mats 4 and the distance that is traveled are so great that the material to be screened forms a flight role in the trough 2, once to the left, once to the right, depending on whether the drive 14 is lifting or lowers.
  • the mats 4 are connected by axial angle iron 5 to ensure that they all lower or raise at the same time.
  • the driven end 18 ' which is required to feed the mats 4 via the support rollers 8 to the clamping bar 9, is not perforated or is not equipped with screen openings.
  • the driven end 18 ' can be detachably connected (or hooked) in front of the support rollers 8 with a flexible web connected to the clamping bar.
  • the length of the sieve trough 2 and the inclined working position 27 of the sieve device 1 force the material to be sieved in the trough 2 to unfold and to migrate to the lower end 15 of the trough. At the end 15 of the trough, the sieve residues fall onto the catch plate 26.
  • the conveyor belt 25 is arranged under the trough 2, which collects and removes the screenable material, cf. 1, 2, 3 and 5.
  • the sieve device 1 can be inclined so much with the help of the hydraulic supports 28 that the material to be sieved in the trough 2 rolls faster or slower to the lower end 15 of the trough, depending on the nature, cf. Fig. 1.
  • the drive 14 of the sieve plate 3 takes place with the help of the clamping bar 9, in which the mat end 18 'of the sieve plate 3 is fixed and which is laterally equipped with the guides 10, cf. 3 to 5.
  • the clamping bar 9 is controlled by the rope deflection rollers 13 and by ropes 12, which are fastened to the pivot point 37 of the sieve plate drive 14 designed as a traction device and are connected to the clamping bar 9, by the rope 12 being extended and retracted in such a way that it rises when the rope is extended , lowered when entering.
  • the traction device 14 is arranged horizontally and travels as long as is required to form the flying role of the screened material.
  • the traction device 14 consists of two roller chains 40, which are driven by chain wheels 41, which are overhung in a frame construction 42, cf. 6, 7 and 8.
  • the roller chains 40 are connected to one another by tabs 43 and a round bar 44.
  • a ball-bearing sliding block 45 is arranged on the round bar 44.
  • the sliding block 45 is guided in a link 46 which is formed in a web 47.
  • the web 47 is in the middle of the roller chains 40 arranged on a movable carriage 48.
  • the backdrop 46 is so long that the sliding block 45 can follow the path of the roller chains 40. Due to the movability of the carriage 48 and the link arrangement 46 in the web, the web 47 is moved back and forth by the circulating chains 40.
  • the articulation points 37 of the cables 12 are articulated on the web 47 such that they lie in the lines of force of the chains 40.
  • the wheels 49 of the carriage 49 are positively guided and are designed in such a way that lateral displacement or breaking out of the carriage 48 is not possible.
  • the force for the roller chains 40 is generated by a chain transmission 50, which is equipped with a slip-on gear 51 and hydraulic motor 52.
  • a driven tapping bar 22 can be attached to the loading side 7 and a roller brush 24 which rotates and sticks into the sieve mesh 19 from the outside on the drive side 23, cf. 4 and 5.
