The subject of this invention is a device for raw material feeding, in particular into an extrusion machine or other equipment relying on continuous or intermittent feed of raw materials, that allows for an easy selection of position of the bin depending on the local conditions. There is equipment known to feed raw materials by means of spring loaders (coiling) according to a French Patent No 530 328. In this approach and also in other similar solutions the construction of the dumping end of the loader makes it difficult to change the location of the loader with the bin attached to it in relation to the equipment being fed. There are known applications aimed at achieving this by using elastic materials for casing but it has a negative effect on the durability of the casing and also the spring because the transport has to be along a curve. In the current invention, an intermediate element, a socket, was employed between the dumping end of the spring loader and the dump bin. The connection between the round dumping end equipped with a stopper ring and the bin is achieved by means of a socket with a blocking clamp. The design of the socket allows for a full turn of the spring loader along the axis of the dumping end in relation to the bin. It is also possible to change the location of the spring loader in the horizontal plane due to the slidable mounting of the socket and sleeve in guides with handles for the positioning of the dumping end after the optimal location of the spring loader in relation to the bin has been selected. The subject of this invention is depicted in examples, where Fig 1 illustrates the general view and Fig 2 shows the cross-section of the device in the A-A plane.
