Definitions

  • the invention relates to a sorting cylinder for seeds and other grain, with a horizontal calibration cylinder, which is mounted and driven on rollers and has a stationary machine housing surrounding the calibration cylinder, which has a material inlet for the material to be sorted and discharge means for the fractions as well as a detachable longitudinal side wall .
  • Such sorting cylinders are used for the exact size separation of grain mixtures.
  • seeds e.g. B. corn kernels
  • the kernels must be sorted out in a very narrow size range.
  • the size of the seed is a quality criterion
  • each individual grain for the seeder must be separated from the total quantity of grain by appropriate allocation devices and sown individually by the machine. The more uniform the outer dimensions of the grains, the more trouble-free the sowing will be.
  • a relatively accurate size classification is also desired for other seeds, such as. B. in wheat, rye, rice, soybeans, grass seeds, etc.
  • the size of coffee beans is also a quality criterion.
  • a typical characteristic of such sorting cylinders is the interchangeability of the working or calibration cylinder. Depending on the requirements, it may be necessary to use very different calibration cylinders: this often means that the sorting cylinder has to be replaced every day.
  • Classic circular sieves are not suitable for a simple change of the sieve drum or the calibration cylinder and can therefore not be used for this type of specific calibration of the grains (e.g. for seed extraction).
  • DE-A-2 543 289 describes a screening drum for processing earth, debris or the like, which has a horizontal rotating cylinder mounted on rollers. This rotary cylinder is freely placed on drive rollers from above and is driven in the desired rotary motion by the drive of these rollers. An interchangeability of the screen drum is not provided in this known device. Rather, according to the teaching of DE-A-2 543 289, a screening machine is to be developed which can be adapted to a wide variety of screenings precisely without changing the screening drum. There is also no cleaning device for the drum drum screen.
  • a rotary drum with a cleaning device for its outer jacket is known, but here the entire device is used for washing coal or the like.
  • easy removal of the rotating drum is also not possible, since the mounting frames for the two ends of the longitudinal shaft of the cleaning device span the drum in its upper half and are supported on the frame surrounding the lower half of the drum.
  • the cleaning device consists of a cylindrical brush which, supported in a suitable manner, is supported from above by the action of gravity against the outer jacket of the screening drum. The rotary movement of the drum also causes the brush resting on the drum to rotate, thereby ensuring that the screen jacket of the rotating drum is continuously cleaned.
  • the invention has for its object to provide a simply constructed sorting cylinder that even by untrained personnel, without auxiliary tools and in the presence of a cleaning device for the outer jacket of the drum particularly easily and without loss of time in and out of the machine housing it can be expanded, so that only a particularly low expenditure of time and costs for installation and removal is required and also a particularly economical storage of the various basic elements is possible.
  • a sorting cylinder of the type mentioned at the outset in that the calibration cylinder rests freely liftable on four support rollers and has at its drive-side end a drive ring provided with a keyway, which is designed with the lateral guide surfaces of a corresponding key profile and as a drive wheel Support roller is engaged by friction, and that a cleaning device for the calibration cylinder is provided, which is driven from the calibration cylinder, is movably arranged relative to the calibration cylinder and rests on its rotary drive under the influence of gravity.
  • the calibration cylinder according to the invention is not only particularly easy and quick to install and remove even when inexperienced personnel are used, but it also has an absolutely reliable functional reliability of the overall device with an incredibly simple structure.
  • the calibration cylinder can be easily inserted on the non-driven end side, placed on the two support rollers there and then on the other Side are placed on the drive roller or the support roller.
  • a further attachment of any drive means is omitted, as is tensioning of loops, belts or chains.
  • the special arrangement and storage of the cleaning device according to the invention also allows the device to be installed and removed quickly with a very simple structure, so that a change of the sorting cylinder, which requires the cleaning device to be removed, can be carried out quickly and even by inexperienced users.
  • Cleaning devices such as sorting cylinders are only lifted upwards and can be immediately removed to the outside via the free side wall of the housing.
  • a particularly advantageous embodiment of the calibration cylinder according to the invention also consists in that the drive ring has a circular cylindrical running surface on the side and the second supporting roller arranged on the drive side likewise has a circular cylindrical supporting surface, the running surface resting on the supporting roller.
  • the calibration cylinder preferably has, on its end opposite the drive in the area of the material inlet, a race which rests on two corresponding circular cylindrical support surfaces of the support rollers. You get a special calming of the running of the calibration cylinder if the drive wheel is rigidly connected to a further support roller on the opposite end side of the calibration cylinder with a continuous drive shaft: this enables the calibration cylinder to be driven on both end sides, which is particularly important for the sieve drum is gentle.
  • the material inlet protrudes into the calibration cylinder and the calibration cylinder ends at a somewhat greater distance than the depth of insertion of the material inlet into the calibration cylinder in front of the corresponding end wall of the machine housing for the purpose of simple installation and removal of the calibration cylinder.
  • the support rollers designed as drive wheels are preferably made of rubber and the drive ring and the race are made of a wear-resistant plastic.
  • a further advantageous embodiment of the invention is that the calibration cylinder and a cleaning device have the drive ring as a common drive member and the cleaning device has an overdrive wheel provided with a corresponding spline.
  • This not only provides a direct drive for the cleaning device, but also gives the possibility of simply lifting the cleaning device out of the device or inserting it into the device in the same way as the calibration cylinder, so that both processes are actually carried out with a single movement can.
  • Both parts mentioned can be driven and guided by a support point and receive a larger or smaller driving force according to their weight.
  • the wedge shape is ideal for the drive, especially in the embodiment described.
  • the wedge-shaped engagement and the wedge-shaped support at the location mentioned also result in unexpected advantages for the whole machine: the calibration cylinder itself is manufactured with great precision as far as the free passages through the openings of the screening drum are concerned. An accuracy of ⁇ 0.1 mm is required for the sieve opening during manufacture.
  • the rotary movement of the drum does not require any particular precision in manufacture.
  • a joint drive of the calibration cylinder and the cleaning device from one and the same drive ring has the further advantage that the distance between the cleaning device and the outer surface of the screening drum is always constant, which applies in part even to the smallest movements (such as vibrations, out-of-roundness, etc.) of the screening drum. This in turn results in a gentle cleaning of the sieve drum shell or the corresponding precision latticework.
  • the cleaning device can be displaced essentially radially to the calibration cylinder in the guide means, the direction of movement being perpendicular or slightly inclined to the vertical.
  • the cleaning device has sliding means which can be inserted into the guide means at the two end sides and which, again preferably, are designed as ball bearings or roller bearings.
  • the cleaning device is designed as a rotating brush or as a beater.
  • the overdrive wheel of the cleaning device is preferably rotatably mounted on the latter and the cleaning device is movably guided relative to the calibration cylinder by means of guide means attached to the machine housing. From this it follows without further ado that a brush or a beater can be easily inserted as a cleaning device from case to case.
  • a further advantageous embodiment of the invention consists in the fact that the calibration cylinder has a drive ring, a race and a paddle shaft, the sieve drum, the race, the drive ring and the paddle shaft being designed as an assembly which can be plugged into one another.
  • the sorting cylinder is preferably designed as a modular system, with a number of different calibration cylinders or a number of differently perforated sieve drums forming the variable basic elements. This makes it possible to keep a number of different, but already assembled or pre-assembled calibration cylinders ready. However, a corresponding number of different sieve drums can also be kept as basic elements without installation and removal.
  • sorting cylinder is designed as a modular unit and either a rotating brush or a beater mechanism is used as a cleaning device.
  • the sorting cylinder is essentially divided into four subassemblies, namely: the machine housing, the calibration cylinder, the cleaning device and the drive.
  • the machine housing 1 which is closed on all sides, rests on the floor with the aid of its two supports 2 and 3 and has a good inlet 4 on one end face and an outlet 5 for the sieve transitions on the other end face and two outlet funnels 6 and 7 for the sieve passages on its underside .
  • the ceiling 8 of the machine housing 1 is screwed tight and the two longitudinal side walls 41 and 42 are detachably fastened as doors by a quick-release fastener 49 in order to be able to easily install and remove and monitor the calibration cylinder 11 and, if necessary, the cleaning device 45.
  • the material inlet 4 is firmly connected to one end wall 9 of the machine housing 1, as is the outlet 5 to the other end wall 10.
  • the calibration cylinder 11 consists of a sieve drum 13 provided with sieve holes 13 or of a wire mesh (FIG. 6), on whose or both ends a race 14 or a drive ring 15 made of plastic are attached.
  • a tensioning disk 16 which is tensioned with the aid of its arms 17 and a tensioning nut 18 against a paddle shaft 19 arranged centrally in the interior of the calibration cylinder 11 with inclined paddles 20, fixes the race 14 with respect to the sieve drum 12.
  • one connects to the paddle shaft 19 welded tensioning star 21, the drive ring 15 non-positively with the sieve drum 12.
  • the paddle shaft 19 is therefore on the one hand a means of conveyance by using its paddles 20 to transport the sieve transitions through the calibration cylinder 11 and on the other hand in connection with tensioning star 21 and tensioning disk 16 tensioning means to hold the race 14 and the drive ring 15 on the screening drum 12, whereby the calibration cylinder 11 is formed as a whole.
  • This is supported in a rolling manner on four support rollers (two support rollers 22 and 23 arranged in the same axis and two drive wheels 24 and 25 also arranged in the same axis).
  • Each of the two plastic rollers 22 and 23 is rotatably supported on an axle stub 44 (FIG. 8) attached to the end wall 9 and 10, respectively.
  • the support rollers 23 and 24 cooperating with the race 14 have a cylindrical running surface, as does the support roller 22, which cooperates with an additional cylindrical support surface 15 'of the drive ring 15.
  • the drive wheel 25 is provided with a spline profile with lateral guide surfaces 43 which engage in a keyway 29 of the drive ring 15 and thus cooperate with the latter in a frictionally locking manner (FIG. 8).
  • the cleaning device 45 is designed as a racket shaft 30 with leaf-shaped rackets 31 (FIG. 3), which are made of plastic and are detachably attached to the shaft 30.
  • the racket shaft 30 is mounted in two roller bearings 32 (FIGS. 4, 7 and 9), which are each slidably received by a U-shaped slideway 33, which acts as a sliding link (FIGS. 4 and 9).
  • the link 33 is fastened to the end wall 9 or 10 of the housing by means of screws 36 (FIG. 4).
  • the racket shaft 30 is arranged transversely axially and in a positionally variable manner relative to the calibration cylinder 11.
  • an overdrive wheel 34 and a drive wheel 35 made of plastic or rubber are arranged in a rotationally fixed manner (FIGS. 1, 2, 7 and 9), of which the drive wheel 34 has a cylindrical running surface and is non-positively connected to the race 14 of the calibration cylinder 11 stands (Fig. 1 and 7).
  • the overdrive wheel 35 is wedge-shaped with respect to its tread and engages with it in the keyway 29 on the drive ring 15 of the calibration cylinder 11, whereby it is non-positively connected to it (FIGS. 1 and 8).
  • a geared motor 37 For driving the calibration cylinder 11 and the racket shaft 30, a geared motor 37 is provided (FIG. 1), which is arranged on the ceiling 8 of the machine housing 1 and carries a chain wheel 38 on its drive shaft in a rotationally fixed manner. A chain 39 connects this to a sprocket 40, which is non-rotatably attached to the shaft 26 of the drive wheels 24 and 25. The torque generated by the geared motor 37 is transmitted via the chain wheel pair 38 and 40 and the chain 39 to the shaft 26 and thus to the drive wheels 24 and 25. These drive the calibration cylinder 11 by frictional engagement via the race 14 or drive ring 15 assigned to them.
  • the race 14 and the drive ring 15 are also in a non-positive connection with the overdrive wheel 34 and the drive wheel 35, so that the drive torque is not only transmitted to the calibration cylinder 11, but on both sides simultaneously to the racket shaft 30 and sets it in rotary motion.
  • the paddles 12 rotating with the calibration cylinder 11 are immersed in the material and, owing to their inclined position on the sieve drum 12, push it axially forward.
  • the large, thick corn kernels are conveyed in this way via the sieve drum 12, flow through the tensioning star 21 at the end thereof and reach the outlet 5 as a sieve transition and into a discharge line for use as the appropriate quality of the seed.
  • the smaller fraction of the corn kernels falls as a sieve passage through the sieve holes 13 or the column-shaped openings between a correspondingly designed wire mesh of the sieve drum 12 into the outlet funnels 6 and 7, from where they pass through their outlet openings z. B. as flat grains form the corresponding flatter quality seeds.
  • the beater shaft 30 constantly rotates and its elastic beaters 31 hit the rotating sieve drum 12 of the calibration cylinder 11, with corn kernels or corn kernel parts still stuck in the calibration openings 13 being pushed back by the beaters or causing them to fall through.
  • the sieve drum 12 is thereby constantly cleaned and its calibration openings 13 are kept free. Since the bat 31 is preferably made of rubber cloth or leather, the blow is more like a vigorous repeated brushing stroke. In this way, it is avoided in any case that the high-precision mesh or perforated plate could be damaged or deformed.
  • the calibration cylinder 11 or the beater shaft 30 has to be removed, for example for a product change, and the sieve drum 12 has to be replaced by one with a different perforation, a long side wall of the machine housing 1 is simply removed by loosening the quick-release fasteners 49 (FIGS. 5 and 6). .
  • the racket shaft 30 and the calibration cylinder 11 are thus easily accessible.
  • the cleaning device 45 can now easily be removed from the U-shaped link 33 of the guide means 48 and by corresponding transverse axial movement from the machine housing 1 (FIG. 5).
  • the calibration cylinder 11 can also be easily removed. This is done by slightly lifting the calibration cylinder 11 from its support roll 22 and 25 and by subsequent axial and transverse axial movement of the same (Fig. 6).
  • the calibration cylinder 11 can be easily installed and removed without auxiliary tools by lifting it from the support point by approximately the height of the keyway 29 of the drive ring 15, then by a length A (see FIG. 2). laterally pulled away from the material inlet 4 and then removed from the machine housing 1 by a transverse axial movement. 7 and 8, an assembly of the moving basic elements with respect to drive and overdrive is shown schematically, the machine housing 1 being omitted for clarity. For the reference symbols, reference is made to the preceding description.
  • FIG. 9 also shows the cleaning device 45 in a schematic illustration, the mobility within the link guides 33 in particular being evident.
  • FIG. 3 shows how the two longitudinal side walls 41 and 42 can be easily lifted out of the lower holder 50 after the quick-release fasteners 49 have been opened.
  • both sides i.e. both longitudinal side walls 41 and 42
  • guide means 48 can be provided on the left and right, ie twice, as z. B. is shown in Fig. 3.
  • the cleaning device 45 e.g. B. in the form of brushes 46 or a beater 47, but could also be driven directly by the drive motor 37 (not shown in the figures).
  • the support roller 22, the drive wheel 25 and the cleaning device 45 must be at an angle of less than 180 ° or the free space for the expansion of the calibration cylinder must be open more than 180 °.
  • the outlets 6 and 7 can, as shown in Fig. 1, be led down or also strongly on one long side, so that when several machines have to be placed one above the other, the lower outlet funnels 6 and 7 are each in the upper right corner (according to the representation of Fig. 3) is arranged. In this case, the left longitudinal side wall can be opened, which has no disadvantages for the solution as shown in FIG. 3, since the cleaning device 45 and the calibration cylinder 11 can be freely lifted out on the same side in this case.
  • the entire product enters the four sorting cylinders 101 at the top and expels the coarsest fraction, which is fed as waste S to further processing.
  • four identical sorting cylinders 101 are used in parallel with one another.
  • the diarrhea of these sorting cylinders 101 is then passed for calibration to a further sorting cylinder group 102, in which each sorting cylinder generates two coarse and one fine fraction for a further downstream calibration.
  • the two coarse fractions and the fine fraction are fed to the further cylinders 103, 104 and 105 for further calibration.
  • the fine fractions of the sorting cylinders 103, 104 and 105 are fed onto drives 106, 107 and 108.
  • the end products are stored in the corresponding storage cells (without reference numerals in FIG. 10), from which they can be removed if required.
  • Calibration with the sorting cylinders is the most important function for the correct size distribution of granular products and takes place in specially built systems.
