Definitions

  • the object of the invention is a spreader for granular mate ⁇ rials, which includes a silo-like reservoir equipped with a base with an opening for the material to be spread, a shut-off plate situated in connection with the opening in the base of the reservoir in order to allow the material to flow in a controlled manner through the opening, and a rotatable spreader plate located beneath the flow opening to throw the material over a large area.
  • the invention is mainly concerned with pushable plate spreaders, but it may also be used in towed or self- propelled machines.
  • Spreaders for granular materials and equipped with a rotating spreader plate are described in US Patent Publications 2,841,401, 3,310,314, and 3,282,591, and in German Application Publication DE 33074468. Material flows onto the spreader plate through the opening made in the reservoir of the wheel-barrow in accordance with the German publication, but the material to be spread easily becomes packed, nor is this in any way a general purpose system when bearing in mind different materials.
  • the intention of this invention is to create a new kind of spreader solution, which will not have the deficiencies of the above mentioned known devices. In particular, reliable spreading operation when using different kinds of granular materials is desired.
  • the characteristic features of a spreader in accordance with the invention are presented in the accompanying Patent Claims.
  • the invention is based to a great extent on the obser ⁇ vation that by opening the entire base, the material in the reservoir is forced into such a flow that prevents vaulting.
  • the flow in accordance with the invention takes place at precisely such a place on the spreader plate that the sprea ⁇ ding is evenly distributed forwards, and not at all in the direction of the user.
  • the concepts forwards and backwards must be reversed if the device is implemented in a towable form.
  • Other advantages and embodiments of the invention appear from the examples of applications presented later.
  • Figure 1 shows a perspective view of the spreader.
  • Figure 2 shows the spreader in partial cross-section, seen from the side.
  • Figure 3 shows the spreader seen from in front.
  • the spreader in Figures 1 - 3 is a model that is pushed and moves on its own wheels.
  • the spreader is built on top of a cart 8 moving on wheels 7, and the spreader plate 6 receives its rotational power from one of the wheels.
  • the spreader includes reservoir 1, which is composed of an upper part in the form of a rectangular prism and a silo- like base 2, in which opening 3 is cut at a slant.
  • This opening is closed by shut-off plate 4, which is attached to the rear part of opening 3 by means of hinge 5.
  • the shut-off plate 4 with its extension 9 is thus able to turn to a limited extent around axle 5.
  • the maximum opening can be adjusted by means of screw device 10.
  • the shut-off plate 3 is operated with the aid of handle 19, which moves a cable mechanism connected to the shut-off plate.
  • the rotating spreader plate 6 is situated eccentrically in relation to the opening of base 2 and the shut-off plate 4.
  • the rotatable plate is secured to the end of an arm set on bearings and it is driven by a serrated belt transmission 11, which is in turn driven by a friction wheel 12 from one support wheel 7.
  • the spreader includes lateral guides 13, which can be turned forwards to the operating position, when the spreading width can be effectively adjusted.
  • the opening 3 of the base 2 of the reservoir 1 is cut at a suitable angle to the horizontal. This angle should be 10° - 14°, in order for the granular material to discharge with a precisely suitable force past shut-of plate 4.
  • the shut-off plate 4 opens at a greater angle than this.
  • the user also tilts the device slightly. The optimal maximum tilt in operation seems to be about 30°.
  • a small tilt of the reservoir has as such no significance and it may indeed be slightly sloping when at rest.
  • the reservoir 1 may even be a rotating component, but from the point of view of use of space the form of a rectangular prism, together with a straight base, provides greater capacity.
  • the extension 9 of the shut- off plate 4 is dimensioned for its intended purpose. Its length is advantageously 20 - 100 % of the length of the opening. Its end determines the point of flow, which should be located on the rear part of the spreader plate, on the side determined by the direction of rotation.
  • the exten- sion section 9 of the shut-off plate can naturally include some kind of adjustment component to adjust its length.
  • the lateral guides consist of turnable supports, in which there are flexible, e.g. rubber, plates.
  • a cable mechanism operates the arm 16 that extends to the side of the shut-off plate.
  • a spreader in accordance with the invention can differ from the example of application, in that it can be arranged to be towable or as a device only carried on a vehicle.

Abstract

L'invention concerne un épandeur pour matériau en grains, comprenant un réservoir (1) dans lequel est placé le matériau à épandre, pourvu d'un fond (2) en forme de silo et présentant une ouverture, une plaque de fermeture (4) associée à l'ouverture (3) du fond (2) du réservoir pour permettre un écoulement régulé du matériau par l'ouverture (3), et une plaque d'épandage (6) rotative, située sous le point d'écoulement du matériau et servant à projeter celui-ci sur une large étendue. L'ouverture (3) du fond (2) présente une inclinaison et la plaque de fermeture (4) est montée sur un axe (5) situé dans la zone du bord supérieur de l'ouverture (3), de sorte que ladite plaque de fermeture (4) peut pivoter pour passer d'une position complètement fermée à une position ouverte correspondant à une grandeur d'ouverture désirée. La plaque de fermeture (4) forme un couloir d'écoulement et la plaque d'épandage (6) est montée, de façon excentrique, en face de l'ouverture (3), de sorte que le point d'écoulement se trouve à l'arrière du point central de ladite plaque d'épandage (6) et sur le côté correspondant au sens de rotation.
