Description

PATENT ATTORNEYS PATENTS AND DESIGNS ORDINANCE SPECIFICATION Centrifugal a limited of 4501 do hereby declare the nature of this invention and in what manner the is to be to particularly described and ascertained in and by th following statement She invention relates to centrifugal strewing in particular for the strewing of mineral wherein the material to he the ertilizer is fed to strewing or distributing members from at least one storage which includes at least one upright partition wall and is supported by a It is an of the invention to simplify and render less costly the supporting frame of the machine and to permit use of a flexible for a synthetic material for making the In known centrifugal strewing machines of the design aforesaid the upright partition walls are rigidly secured to the storage hopper but not to the frame supporting the fhe complete hopper and the frame thus form two separate fhe disadvantage of these strewing machines consists in the fact that for supporting the weight of the filled hopper and absorbing the torsional stresses produced by the travelling shocks a rather heavy supporting frame consisting of several component elements is required to which the storage hopper is secured by means of connecting and which at least partly encloses the In accordance with the invention these disadvantages are overcome and a lowering of costs as compared with conventional designs is in that the partition wall connected to the Owing to this arrangement it a part of the supporting The in the filled rests with its total on the partition which is rigidly connected with the supporting In this construction that part of the supporting frame enclosing the hopper he omitted since all the stresses occurring in operation are absorbed the lover frame the According to a further feature of the invention the plates of the hopper are rigidly connected with the partition us the storage hopper becomes additionally supported by the bottom plates connected with the partition whereby a better distribution of the bearing surface over the supporting parts of the frame and at the same time a reinforcement of the partition wall are This embodiment of the invention also permits the use of synthetic materials for the hopper since these are in this case supported by a rigid and stable A considerable reduction in costs is achieved if the bottom plates and the partition wall are made i one In order to make the supporting frame simple and therefore cheap and yet largely free from torsional the invention as a further to weld the hopper to the partition When the centrifugal strewing machine is being assembled is absolutely necessary previously to adjust the strewing members in relation to the outlet because the strewing precision of the machine depends on according to a feature of the the mechanism actuating the strewing or the inner partition are disposed at least one plane displaeeable relative to the supporting frame known auxiliary another feature of the invention the partition may also be provided with known elements for the the delivery gate apertures or the This makes superfluous the provision of the separately attached In an advantageous embodiment of the invention the partition wall has the shape of a roo central ensures an extremely stable and mounting of the storage In addition the delivery gate valves can be mounted on this central which permits an inexpensive and simple design of the actuating levers of the delivery gate it is sufficient to journal these levers at one place and they can be reached from the seat of the A yet further feature of the invention provides that an additional transverse beam is mounted to the upper part of the supporting which encloses the storage hopper at least so that the walls of the filled storage hopper bear against this transverse via conventional this flexible for example synthetic can be used for the whereby the production cost of storage hopper lowered
