Definitions

  • the present invention relates to a Municipal vehicle z. B. Truck attachable spreader for Spreading spreading material on traffic areas, comprising a grit container with a bottom, two side walls and two end walls, one along the bottom of the grit container in its longitudinal direction extending extraction and metering device and one of them loaded, on the back of the spreader arranged spreading device.
  • Generic spreaders are for example from DE-U-1925849, EP-B-0131761, FR-B-2721627, DE-A-4008773, US-A-3559894, DE-C-3829624, DE-C-3035360, DE-A-2830056 and DE-A-4211288 are known.
  • the spreader known from DE-A-19616659 has not proven in practice. In particular, it suffers under two significant disadvantages: Firstly can only be spreading materials with this spreader apply dry and free-flowing condition; the Spreading slightly damp sands is in contrast not possible. Furthermore, at the end of the emptying of the Spreading material container towards the dosage of the spreading material inaccurate; this is because towards the end of the emptying process as a trigger and metering device intended snail over a longer one Period is no longer completely filled.
  • the bottom of the grit container comprises two sections, each around a horizontal, extending longitudinally, near the Trigger and metering device arranged axis between a basic position and an inclined one Tracking position are pivotally mounted, on the two bottom sections are inclined adjusting lifting device acts.
  • the invention Spreader is characterized in that the Inclination of the two on both sides of the trigger and metering device arranged bottom sections of the Spreading material container can be changed, namely between a basic position and a maximum inclined tracking position.
  • the two bottom sections can in particular in their basic position in run essentially horizontally and in their Take up an inclination up to about 50 ⁇ .
  • the bottom sections reliably for deduction and Dosing device after.
  • the center of gravity should not be higher than at the beginning of the spreading insert when completely filled Grit container.
  • the spreading device according to the invention stands out, however not just through an expanded range of deployable materials and an improvement in Dosing behavior towards the end of the spreading operation; moreover, by the design according to the invention the spreader is also more complex to use Aggregates as they are related to funding and Vibrating floors are required, can be dispensed with.
  • a particular advantage of the spreading device according to the invention is further that even at the end of the spreading operation at maximum inclined floor sections Driver's view to the rear not at all or is at least not significantly impaired. Because even with the maximum raised (inclined) floor sections is in the area above the deduction and Dosing device between the end wall sections, which expediently with the bottom sections of the Spreading material container are firmly connected and with these be pivoted (see below), an approximately V-shaped Section through which there is a clear view to the rear given is.
  • a preferred development of the invention Scattering device is characterized in that the trigger and Dosing device as a screw conveyor with a Snail channel is formed.
  • the trigger and Dosing device as a screw conveyor with a Snail channel is formed.
  • the articulated connection can be done in different ways be realized. Consider, for example metallic hinges, if necessary with a flexible film are covered, made of polyurethane manufactured film hinges or others as such known articulated connections. It can be used However, the present invention in the same way Relation to withdrawal and trained as a belt conveyor Dosing devices. In this case, the both grit container bases in particular articulated be connected to the belt box.
  • the two floor sections with regard to their lifting movement synchronized to each other.
  • they are both bottom sections always the same strength for deduction and Dosing device inclined. In this way become asymmetries that affect the driving behavior of the truck can negatively influence, prevented.
  • the synchronization of the lifting movements explained above of the two bottom sections to each other especially via a mechanical positive coupling respectively.
  • suitable hydraulic or pneumatic control especially when the lifting device hydraulic cylinder or hydraulic cushions or pneumatic bellows includes (see below).
  • each end wall preferably two each connected to the bottom sections, together with these include pivotable end wall sections.
  • each end wall also includes a (Fixed) end wall element on which the two pivotable end wall sections sealingly guided are.
  • Those end wall elements close off one between the two swiveling end wall sections existing in their basic position, approximately V-shaped Excerpt with regard to the Swiveling of the two end wall sections is provided.
  • To seal the pivotable End wall sections on the fixed end wall element can in particular polyurethane strips be provided.
  • the side walls of the grit container of the spreader according to the invention with connected to the bottom sections of the spreading material container are.
  • the side walls of the grit container along with its bottom sections gradually in the sense outlined above raised.
  • a combination is particularly advantageous of the training courses set out above in the Senses that the grit container two articulated stored, on both sides of the trigger and metering device arranged container sections includes which in turn one floor section, two End wall sections and a side wall include.
  • the lifting device hydraulic cylinder comprises, by means of the two-circuit vehicle hydraulics are operable.
  • the act particularly preferred Hydraulic cylinder in this case on the Lifting device further includes swivel arms Rollers, which are at the bottom of the bottom sections unroll.
  • the swivel axes of the swivel arms lie at a lower level than the swivel axes the floor sections. This allows a particularly space-saving accommodation of the lifting device below the grit container with the result that the focus is further favored.
  • lifting device instead of the hydraulic cylinder can within the scope of the present Invention provided lifting device according to a other preferred development of the invention as well Hydraulic or pneumatic cushion include the Gradually raise the floor sections with Pressurized liquid or pressurized gas, especially with Compressed air to be filled. This further training too is again characterized by a particularly low Space requirement of the lifting device with the advantage a particularly low center of gravity of the spreader.
  • the adjustment of the inclination of the bottom sections of the Spreading device according to the invention can be manually by Drivers of the truck take place, who the conditions in Spreading material container observed (see above). For Relief of the driver and to avoid this is distracted from his other tasks, can However, within the scope of the present invention Control can be provided on the lifting device acts and a the degree of filling of the grit container representing signal evaluates. As such, representing the filling level of the spreading material container The signal comes in particular the sum of the revolutions considered as the extraction and metering device intended screw conveyor since the beginning of Has completed spreading operations. The drive torque too the extraction and metering device forms a suitable one Basis for the filling level of the grit container representative signal.
  • the spreader 1 is on one end wall 2 and two side side walls 3 comprehensive platform 4 des Carrier vehicle placed in the form of a Unimog 5. It comprises a frame 6, a grit container 7, one extending in its longitudinal direction deduction and Dosing device 8 in the form of a screw conveyor 9 and a a motor-driven spreader plate 10 comprehensive spreading device 11, the rear on Scattering device 1 is arranged and deducted and Metering device 8 is loaded with spreading material.
  • the Screw conveyor 9 is a along the bottom of the grit container 7 extending screw channel 12 assigned.
  • the spreading material container comprises two container sections 13, each of a bottom portion 14, one Side wall 15 and two end wall sections 16 consist.
  • Each of the two container sections 13 is around a horizontal, longitudinally extending Axis 17 pivotally mounted.
  • the two axes 17 are arranged near the extraction and metering device 8, by placing each of the two bottom sections 14 over one Hinge strap 18 or alternatively a PU film hinge 28 with the associated edge of the screw channel 12 connected is.
  • Container sections can be between a basic position, in which the bottom sections 14 run approximately horizontally (solid lines), and a strongly inclined one Tracking position in which the bottom sections are at an angle are inclined from about 45 ° to the screw conveyor 9 (dash-dotted), any inclination take in. So that the end wall sections 16 incline the container sections 13 do not hinder the inner edges 19 beveled, so that between the two end wall sections 16 each end wall, if the container sections 13 assume their basic position, there is an approximately V-shaped cutout.
  • This Cutout is in the area of each end wall by a fixed end wall element 20 closed, the with the spreader shown over the entire Width of the spreader extends and in the Basic position of the container sections 13 the end wall sections 16 completely covers from the outside.
  • the End wall sections 16 lie in the region of their edges 19 sealing with PU strips on the respective End wall element 20.
  • the one for adjusting the inclination of the two container sections 13 provided lifting device 21 comprises each side at least one swivel arm 22 which by one longitudinally extending axis 23 pivotable is stored and at its opposite end Role 24 carries.
