    专利说明:

    The invention relates to a device for loosening bulk goods in a storage space according to the preamble of claim 1. This is particularly suitable for use in storage containers or bunkers for pellets or wood chips, which are fed via a screw conveyor or a spiral conveyor to be transported to the burner of a heating system. The bulk material passes through an inlet opening of a housing receiving the screw conveyor into a conveyor pipe which leads to the combustion chamber of the heater. A vibrating plate is attached above the inlet opening of the housing, which is set in motion by the movement of the rotating screw conveyor. This loosens caked-up pellet lumps so that they can be transported through the conveyor pipe without any problems.
    A device of the type described is known from DE 20 2008 004 400 U1.
    The installation and assembly of such devices according to the prior art require care and accuracy, since as a rule the already installed delivery pipes within the storage space must be cut open axially in several places in order to install the device. The separating cuts must be made very precisely in order to create a predetermined opening, through which the pellets or wood chips are fed into the conveying pipe at a correct angle.
    The invention has for its object to remedy this situation and to provide a device that can be prefabricated by the manufacturer so that a quick and exact installation in the storage space is possible.
    To achieve this object, a housing is provided according to the invention, which is attached to each side wall outside a connecting piece for the attachment of a screw enclosing the conveyor tube, which is guided inside the housing through a partially cylindrical bottom wall ending on the side walls.
    This solution has the advantage over the prior art that the device is available as a ready-to-install unit which can be connected to the delivery pipes in the storage space without further adaptation measures. Additional measures for adaptation, for example by cutting an access opening on the conveyor pipe, are unnecessary.
    In a development of the invention it is provided that the bottom channel is attached with its upper edge to the rear wall of the housing and has a low-friction coating on its inside according to a further feature.
    According to a further feature of the invention, the inlet opening below the vibrating plate is limited by a transverse wall which adjoins the two side walls. It is particularly advantageous if two parallel fastening projections protrude from the lower edge of the transverse wall of the housing and are used for fixing the housing to a floor of the storage space. These fastening projections, which protrude outwards in addition to two further fastening projections on the side walls of the housing, ensure that the housing is fixed in a defined manner on the floor of the storage space and prevent tipping or shifting due to the not inconsiderable weight forces that act on the housing , is caused. In practice, with a full storage space, weight loads of almost one ton per cubic meter of bulk material act on the roof of the housing. Due to the fastening projections on the lower edge of the transverse wall and thus in the front area of the housing, the weight forces are absorbed in such a way that the position of the housing is retained.
    According to a particularly preferred embodiment, the device is composed of a basic module consisting of the housing, the rear wall with the gear mounted thereon and a transverse wall with a fastening projection.

    AT 16 653 U1 2020-04-15 Austrian Patent Office [0010] The invention is explained below using an exemplary embodiment which is shown in the drawing. Show it:
    Figure 1 [0012] Figure 2 [3] [0014] Figure 4 [0015] Figure 5 shows the perspective view of a device according to the invention in the ready-to-install state, a side view of the device of Figure 1, a sectional view of the device in the level III-III of FIG. 5, a front view of the device, the top view of the device when two delivery pipes are connected to the two connecting pieces of the housing, the front view of two housings with attached delivery pipe connections, a top view of the two devices of FIG completed coupling of the two connecting conveyor pipes and an exploded view of a modular device.
    Figure 6 [0017] Figure
    In Figures 1 to 4, a device 10 according to the invention is shown, which consists essentially of a housing 12 made of sheet metal and can be attached to the bottom of a storage space, not shown, which serves to accommodate bulk material , for example pellets or wood chips.
    The housing 10 is delimited by two parallel side walls 14 which are connected to one another by a rear wall 16 and a roof 18. A horizontal projection in the manner of a screen 20 projects forward from the roof 18.
    On each side wall 14 of the housing 12, a cylindrical connecting piece 22 is attached to the outside, onto which a delivery pipe 24 (see FIGS. 5 to 7) can be placed, which can be clamped onto the connecting piece 22 via a pipe clamp 26.
    Within the housing 12, the two connecting pieces 22 continue through a partially cylindrical floor channel 28 which, according to FIG. 3, has a low-friction, noise-insulating coating 30 on its inside.
    As Figure 3 shows, the upper edge of the floor channel 28 is attached to the rear wall 16 of the housing 12. This results in a coherent covering of the rear of the housing 12 by the bottom channel 28 and the rear wall 16.
    Through the two coaxial connector 22 of the housing 12, a conveyor screw 32 is guided after the installation of the device 10, which is rotatably driven and thereby the bulk material (pellets, wood chips or the like.) Transported through the interconnected conveyor pipes 24 according to Figure 7 .
    The housing 12 has on its front side an approximately rectangular inlet opening 34 through which the bulk material reaches the area of the screw conveyor 32. Above the inlet opening 34, a vibrating plate 36 ends which, according to the teaching of the utility model 20 2008 004 400 mentioned at the outset, is set in a reciprocating motion via a gear 38 and a driver (not shown), so that bulk material parts lying on the outside of the vibrating plate 36 are loosened, before they reach the area of the screw conveyor 32 through the inlet opening 34.
    From Figures 1 and 4 it is clear that the inlet opening 34 below the vibrating plate 36 is limited by a transverse wall 40 which adjoins the two side walls 14. Two parallel fastening projections 42 protrude from the lower edge of the transverse wall 40, with which the housing 12 can be anchored to the floor of the storage space by means of screws, not shown. Two further horizontal fastening projections 42 ′ protrude outward from the two side walls 14 of the housing 12, which is particularly the case with the figures

    AT 16 653 U1 2020-04-15 Austrian patent office and 5 shows.
    Figure 8 shows an exploded view of a device according to the invention, which is assembled to facilitate assembly and repair work from individual modules that can be replaced if necessary without changing the entire device. The basic module A consists of the housing 12, from whose two side walls 14 the connecting pieces 22 extend outwards. These have an axial slot 44 to make it easier to attach the delivery tubes 24. Another module B consists of the rear wall 16 on which the gear wheel 38 is permanently supported. This is opposite the vibrating plate 36. Both are fixed by screws 46 after being attached to the side walls 14. A third module C consists of the transverse wall 40 with the fastening projection 42, which is also inserted between the two side walls 16 and fixed there with screws 46.
    It is advantageous if the pitch of the screw conveyor 32 coincides with the helical toothing of the gear 38 in order to keep the driving forces as low as possible.
    The modular system according to FIG. 8 allows the module A to be easily repaired in the event of malfunctions, for example due to foreign bodies or swelling material to be conveyed, without having to completely remove it. This applies in particular to premature wear of gear 38.
