    The invention relates to a device for cleaning harvested pumpkin seeds from adhering pulp with a lying sieve drum through the sieve coat the dissolved pulp from the pumpkin seeds pulp under a restraint of the pumpkin seeds is ausförderbar.
    For harvesting pumpkin seeds it is known (AT 343 397 A) to crush the pumpkin fruits picked up from the field and to dispense the pumpkin seeds from the pulp to a sieve drum from which the pumpkin seeds are deposited through the sieve jacket while the retained pulp is discharged over the sieve drum becomes. To improve the separation efficiency and protection of the pumpkin seeds, the sieve sheath of the sieve drum is composed of semi-circular rings (AT 373 510 A), so that the flat pumpkin seeds can align themselves in the tapering sieve gaps between the rings. Despite this measure can not be prevented that with the pumpkin seeds and pulp and spermatozoa are separated from the sieve drum through the sieve jacket. It will therefore require a post-treatment to clean the pumpkin seeds harvested in this way. This post-treatment usually takes place in a lying, in the conveying direction downwardly inclined screen drum, which is acted upon in a over the length of the wire jacket extending, comparatively narrow suction with a suppression, so that the pulp and the spermatozoa can be sucked through the basket, while the pumpkin seeds be retained by the screen jacket and discharged in the axial direction of the drum. Apart from the fact that by sucking the pulp and the spermatic threads no higher 2/13 2
    Requirements appropriate cleaning effect on the pumpkin seeds can be exercised, require the blower required for the suction a comparatively high energy input. In addition, a significant environmental impact due to the flow-induced noise is expected.
    The invention is therefore based on the object, a device for cleaning harvested pumpkin seeds of adhering pulp in such a way that with a relatively low energy use effective cleaning of the pumpkin seeds can be ensured, while maintaining a low noise level.
    Starting from a device of the type described, the invention solves the problem by the fact that two concentrically mounted against each other relatively rotatable and an annular gap for receiving the Fruchtfleischbehafteten pumpkin seeds are provided between them releasing drums, one of which the screen drum and the other a conveyor drum Forming transverse to the circumferential direction, applied to the screen drum pressure bars.
    By the proposed measures, the pulp and existing spermatozoa is mechanically discharged through the basket of the sieve drum, which sets due to a relative movement between the basket and the pumpkin seeds abrasion of the pulp from the pumpkin seeds, whereby the cleaning effect can be significantly improved, with a comparatively low energy consumption and a significantly reduced noise level. The promotion of the pumpkin seeds to be cleaned in the annular gap between the sieve drum and a concentric conveyor drum is an essential prerequisite for being able to attach the pumpkin seeds to be cleaned to the screen jacket of the sieve drum. For this purpose, the pressure bars extending transversely to the circumferential direction, which abut the screen jacket of the screen drum, due to the relative rotation between the screen drum and the conveyor drum cause a storage area for the items to be cleaned, so that not only for a corresponding abrasion of the pulp or the spermatozoa of the Pumpkin Seeds is ensured, but also the abraded pulp residues with the spermatozoa are conveyed safely out of the annular gap between the sieve drum and the conveyor drum by the sieve sheath.
    In order to support this conveying effect of the pressure bars with respect to the discharge of the pulp and the spermatozoa from the annular gap, the pressure bars can be inclined relative to the screen casing in the circumferential direction, wherein there is a gap tapering in the circumferential direction between the pressure bars and the screen casing in the conveying direction. If the pressure strips are resiliently pressed against the screen jacket, then not only an independent wear compensation is ensured, but also supports the pulp promotion radially through the sieve drum. In addition, the pressure bars may optionally dodge against foreign bodies.
    Within the annular gap between the drum and the conveyor drum is to provide sufficient conveying movement in the axial direction, which generally requires additional measures. In order to force a compulsory promotion of the cleaning material in the axial direction through the annular gap, the conveyor drum may have at least one helically arranged conveyor web. In connection with this conveyor web, particularly advantageous construction conditions result if the pressure bars provided along the conveyor web have a smaller length than the pitch of the conveyor web and overlap each other in the direction of the drum axis, so that the cleaning material is inevitably conveyed into the area of the pressure bars. Since these pressure strips overlap each other in the direction of the drum axis, a gapless storage area for the items to be cleaned is ensured over the entire axial conveying path.
    Since it only depends on the relative rotation of the screen drum relative to the conveyor drum, the conveyor drum could enclose the screen drum at a distance. However, then the pulp would have to be discharged with the spermatic threads from the inside of the sieve drum in the axial direction, which brings constructive difficulties. For this reason, simpler construction conditions result when the sieve drum encloses the conveyor drum, because in this case the pulp and the spermatoic fibers can be removed from the outside of the sieve casing with any other contaminants present. If the sieve drum is driven in rotation, the separated product can be detached from the outside of the sieve sheath in a simple manner by scrapers and can be given to a connected discharge conveyor. For the conveying and cleaning action of the cleaning material in the annular gap between the screen drum and the conveyor drum, it is recommended to additionally drive the conveyor drum, in opposite directions to the screen drum to achieve a correspondingly high relative rotation between the drums at relatively low speeds of the two drums.
    In the drawing, the subject invention is shown, for example. Show it
    1 shows a device according to the invention for cleaning harvested pumpkin seeds of adhering pulp in a schematic longitudinal section and Fig. 2 shows this device in a section along the line II-II of Fig. 1 on a larger scale.
    The device shown has two horizontal, concentric drums, namely a screen drum 1 and a conveyor drum 2, which leave free between them an annular gap 3 for receiving the Guts to be cleaned. The arrangement is made such that the conveyor drum 2 is arranged on a support shaft 4, which is rotatably supported at both ends in a chain 5 indicated frames 5 associated bearings 6. The conveyor drum 2 enclosing the screen drum 1 is supported by means of bearings 7 and 8 via support stars 9 on the support shaft 4.
    To promote the harvested in the usual way pumpkin seeds in the annular gap 3 between the screen drum 1 and the conveyor drum 2 is a screw conveyor 10 in extension of the support shaft 5 for the conveyor drum 2, which is connected to a drive 11. The screen drum 1 is driven via a separate drive 12 with the interposition of a chain drive 13 in the opposite direction to the conveyor drum 2 5/13 5 driven. In order to absorb the transverse forces exerted on the screen drum 1 by the chain drive 13, the screen drum 1 can additionally be radially supported via bearing rollers 14.
    The screw conveyor 10 opens into a connecting cone 15 of the sieve drum 1, so that the pumpkin seeds to be cleaned pass through the connecting cone 15 in the annular gap 3 between the conveyor drum 2 and the screen drum 1, where they by a conveyor drum 2 helically wrapping conveyor web 16 for the promotion be detected by the annular gap 3.
    The conveyor web 16 of the conveyor drum 2 are distributed over the drum length and the circumference, extending in the direction of the drum axis pressure strips 17 associated, preferably resiliently against the screen jacket 18 of the screen drum 1 and extend inclined relative to the screen jacket 18 in the circumferential direction, as shown in FIG can be removed. The funded over the conveyor bar 16 through the annular gap 3 cleaning material is therefore accumulated in the pressure bars 17 with the effect that the pulp and the spermatozoa of the pumpkin seeds by the passing screen 18 of the screen drum 1 abraded and subsequently in the area between the pressure strips 17 and the screen jacket 18 resulting, circumferentially tapering gap are pressed through the screen jacket 18, while the freed from these impurities pumpkin seeds are retained and further promoted through the annular gap 3. Since the pressure bars 17 are arranged distributed over the circumference and the length of the conveyor drum 2 and each form a cleaning stage, the pumpkin seeds are freed in several stages of cleaning the pulp and the spermatozoa to get on the discharge side end side of the conveyor drum 2 in a discharge chute 19 which can be connected to a collection container.
    The with the help of the pressure bars 17 through the sieve 18 mechanically conveyed outward pulp with the spermatic threads and any impurities is scraped off by a spring-loaded scraper 20 from the outer surface of the sieve 18 and falls into a discharge conveyor 21, the game in Ausführungsbei-6/13 6 game is designed as a discharge screw. Since the device can be mounted on the frame 5 on a pumpkin harvesting machine, in the course of pumpkin seed harvesting the additional cleaning of the pumpkin seeds by the device according to the invention immediately after the harvesting process can be carried out, the detached from the pumpkin seeds pulp on the discharge conveyor 21 again the Floor can be supplied.
    It need not be emphasized that the invention is not limited to the illustrated embodiment. Thus, the drums 1,2 are usually arranged in an enclosure 22, which is indicated only by dash-dotted lines. The storage of the screen drum 1 and the conveyor drum 2 into each other is of course not mandatory, as it is not mandatory to supply the cleaning material via a screw conveyor 10. The pressure bars 17, but also the conveyor web 16 need not be made from corresponding profiles. So it might be advantageous under certain circumstances, form these construction parts as brush strips. The scraper 20 for cleaning the screen shell 18 could for example also be designed as a roller brush. It depends only on the function of these construction elements, and not on the structural design. 7.13
