Definitions

  • the invention relates to a centrifugal spreader according to the preamble of claim 1.
  • centrifugal spreader is known for example from DE 697 01 887 T3.
  • This centrifugal spreader has a frame to which a reservoir is attached with two discharge funnels.
  • the upper area of the outlet funnel opens into two outlet funnels, which are each closed off by metering devices at the bottom.
  • These metering devices carry the material located in the reservoir container and the outlet funnels in adjustable amounts to the centrifugal discs arranged underneath the metering devices and rotatingly driven.
  • the reservoir with its two outlet funnels consists of front, rear and side walls, as well as walls of the roof-shaped central part.
  • the walls of the reservoir and the discharge funnel are formed as independent walls and connected to a reservoir with discharge funnel by screw. This results in a time-consuming installation of the container Vorratsbe with the outlet funnels.
  • centrifugal spreaders have become known in practice, in which the Vorratsbe open container in at least two outlet funnels, which also consist of individual walls. These independent walls are connected by means of welded connections to a Vorratsbe container with two discharge funnels.
  • This design is time-consuming manufacturing technology.
  • the welds by means of which the individual walls are joined tend to rust in the rough agricultural operations, with some aggressive and rust promoting materials being applied.
  • the invention has for its object to improve the production of storage containers, which opens into two discharge funnel, substantially in time, with rust-forming points to the reservoir and discharge funnel to be minimized.
  • This object is achieved in that the reservoir is formed with its outlet funnels in one piece from a sheet steel plate in its container shape by deep drawing operations as a single deep-drawn part.
  • a container opening out in two outlet funnels Vorratsbe is created in closed production, which is manufactured and configured as a single component without joints and seams.
  • such a part can be designed with corresponding curves and inclinations, so that an advantageous slipping of the material in the storage container and the outlet funnels to the metering without appreciable congestion compared to the embodiments of storage containers according to the prior art.
  • the advantageous embodiment of the reservoir with two discharge funnels to provide the separate discharge funnels, which are completed with metering, can be achieved in that the discharge funnels are separated by a trained by the deep drawing operations roof-shaped area.
  • each outlet funnel in the walls of each outlet funnel a step-shaped, preferably circumferential shoulder embossed and / or is formed.
  • a sieve element in the region of the step-shaped shoulder can be used in a simple manner.
  • An advantageous arrangement and attachment of the sieve element, which also serves as a security element, can be achieved in that in the region of the stepped shoulder a sieve element is arranged by means of support and / or support elements.
  • At least one subsequent attachment element is arranged at the upper peripheral region of the reservoir.
  • the capacity of the reservoir can be easily adapted to the particular given conditions of use.
  • a simple arrangement of stirring elements above the metering device can be ensured by fastening elements for the arrangement of the metering devices, preferably with a welded connection, being arranged on the lower region of the outlet funnel.

Abstract

L'invention concerne un épandeur centrifuge destiné à épandre des matières pulvérulentes, doté d'un réservoir (2) débouchant dans au moins deux trémies de décharge (3) et supporté par des éléments de châssis (1), les trémies de décharge (3) étant respectivement fermées par des dispositifs de dosage (15). Des plateaux dotés de pales d'éjection sont entraînés en rotation et disposés sous les dispositifs de dosage (15). Dans le but de diminuer le temps de fabrication des réservoirs (2) débouchant dans deux trémies de décharge (3) tout en devant minimiser les points de corrosion sur le réservoir (2) et les trémies de décharge (3), le réservoir (2) avec ses pales d'éjection (3) est selon l'invention formé d'un seul tenant à partir d'une plaque de tôle dans sa forme de réservoir par des procédés d'emboutissage profond en tant que pièce d'emboutissage profond unique.
