Description

Grille holder for cereal mills

Object of the invention

The present invention relates to a rack support for cereal mills; of the type intended to be coupled to the body of a cereal mill to delimit a cylindrical crushing chamber, each grille holder support comprising a frame provided with stiffener crossbars and delimiting a hollow as a cylindrical sector; said frame forming a support for the assembly of a grill formally consistent with the hollow of the frame and constituted by a perforated plate for the output of the crushed cereal in the crushing chamber.
tion.

Background of the invention

Certain cereal mills, such as hammer mills, have a crushing chamber laterally delimited by a variable number of supports grille holders that together define a cylindrical wall according to the contour of the aforementioned chamber of trituration.

Traditionally each support grille holder consists of a curved frame which delimits a hole as a cylindrical sector, forming said frame a support for mounting a chord grill formally with the hollow of the frame and constituted by a plate perforated through which the crushed cereal comes out in the chamber Crushing

Currently the perforated plate is fixed by its contour to the corresponding frame by means of a plurality of screws and corresponding nuts squeeze in.

This assembly greatly increases the fabrication of the frame and perforated plate, since it is necessary machining in them the holes necessary for the assembly of the fixing screws, another drawback of this fixing using screws is that both mounting the perforated plate as its subsequent disassembly for replacement tasks or Maintenance requires excessive time.

Another drawback of this assembly is that the grill fixing screws loosen due to the vibrations produced during grinding, which causes some clearances that prevent proper operation of the grill and they influence the final quality of the ground product obtained.

Therefore, the technical problem that arises is the development of a rack holder for cereal mills that allow lower manufacturing costs and simplify plate assembly and disassembly tasks perforated, however guaranteeing its stability in the position of mounting.

Description of the invention

To solve the aforementioned problems, devised the grille holder for mills of cereals object of this invention to present some constructive features aimed at simplifying tasks for mounting and dismounting the perforated plate with respect to the frame, and to reduce the machining tasks of the perforated plate and the frame during its manufacture, with the consequent saving of costs

For this and according to the invention the frame it has longitudinal, open guides at the straight ends at least by a first curved end of the frame, to allow the sliding mounting of the perforated plate on said guides; presenting said frame at the second curved end at least one retaining stop of the front end of the perforated plate in the Mounting position.

Obviously the sliding plate assembly perforated in the longitudinal guides of the frame is made of a Quick and easy way.

Additionally and according to the invention this grill holder includes a lid removable provided with fixing means on the first curved end of the frame setting the end closure corresponding of the longitudinal guides and consequently the perforated plate retention in mounting position.

To ensure stable plate retention perforated in the mounting position relative to the frame, just fix the removable cover over the first curved end of the frame, said cover being released when the plate needs to be removed perforated to perform its replacement or any task of maintenance.

In one embodiment of the invention the lid Detachable is constituted by a flat plate that has a curvature consistent with that of the first curved end of the frame, which allows the lid to be superimposed in the mounting position on the first curved end of the frame closing the end corresponding of the longitudinal guides on which it is based the perforated plate.

In an embodiment of the invention the means of detachable cover fixing are made up of threaded stems integral to said removable cover, which they are introduced in holes defined for this purpose in the first curved end of the frame and by respective tightening nuts.

A reduced number of threaded stems, from order of two or three, it is enough to keep the lid detachable in the fixation position since said cover Detachable is not subject to significant efforts and its fundamental mission is to retain the perforated plate in the position of assembly with respect to the frame.

In one embodiment of the invention the plate Detachable comprises on its outer side handles for the gripping and handling of the grill holder, for example during placement or extraction in the mill.

According to the invention the first end Curved frame presents on its inner side, and at least in one part of its length, a curved plate facing inwards of the framework and that forms additional means for support side of the perforated plate in the mounting position.

This curved plate is interrupted in the zones corresponding to the holes defined in the first curved end of the frame for mounting the lid stems, so that it does not constitute a hindrance during placement or extraction of the corresponding tightening nuts on the ends of threaded stems.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative and not limiting, the following has been represented:

- Figure 1 shows a perspective view of an example of the rack holder for cereal mills with perforated plate and lid mounted on the framework.

- Figure 2 shows an exploded view aligned in Grille holder stand perspective.

- Figure 3 shows a plan view top of grill holder with plate perforated mounted on the frame and without the removable cover.

Preferred Embodiment of the Invention

As can be seen in the attached figures the grill holder includes: a frame (1), a perforated plate (2) and a removable cover (3).

The frame (1) delimits a hollow as a cylindrical sector and is provided with stiffener crossbars
(eleven).

The frame (1) presents at the straight ends longitudinal guide paths (12) open at the first end curved (13) of the frame in order to allow the sliding assembly of the perforated plate (2) in the frame guides.

The second curved end (14) of the frame (1) presents in this embodiment two stops (15) for the gripping the corresponding end of the grill (2).

The first curved end (13) of the frame (1) It has holes (16) for mounting and fixing the lid detachable (3) and, on its inner side a curved plate (17) which forms additional means for lateral support of the perforated plate (2) in the mounting position.

As can be seen in Figure 2, said curved plate (17) is interrupted in the zones corresponding to the holes (16) in order not to interfere in the assembly and fixing of the removable cover (3).

The perforated plate (2) has a plurality of holes (21) with a drilling coefficient suitable for milling and specifically to allow passage through the same ground cereal.

The cover (3) is constituted by a plate curvature plane according to the first curved end (23) of the frame (1), said removable cover (3) presenting on its side outer handles (31) and on its inner side some stems threads (32) that are introduced through the holes (16) of the frame (1) establishing the fixing of the cover (3) with respect to the frame by means of tightening nuts (33) that are mounted on the ends of the mentioned threaded rods (32).

As can be seen in figure 1, in the mounting position of the grille holder, the removable cover (3) is superimposed on the first end curved (13) of the frame and over the open end of the guides longitudinal (12) retaining the perforated plate (21) in the mounting position with respect to the frame (1).
