Definitions
- the present invention relates to a system for mounting the peak holder sectors on a slicer wheel or a strawberry (or cutter) drum, allowing rapid mounting of the sectors, as well as changing the working direction of rotation of the wheel or drum around its axis.
- the device according to the invention overcomes the drawbacks mentioned above.
- It comprises supports fixed (generally at regular intervals) on the periphery of the wheel (or drum) and which have a generally elongated shape in the circumferential direction limited by a base, two lateral surfaces and an external surface.
- the base is rigidly fixed to the outer surface of the wheel (or of the drum) by welding, mechanically or any other suitable means.
- This shape has symmetry with respect to an axis, which is generally perpendicular and concurs with the axis of the wheel (or of the drum); the lateral faces form, at their outer end, with the perpendicular to the axis of symmetry, an angle (a) less than 90 °; preferably, the end of the lateral faces converge more quickly than the spokes which pass through the external ends of the support.
- These supports can be drilled with at least two holes or openings, symmetrical with respect to the radial axis of the support for the removable fixing of the peak holder sector, by any known means (elastic pin or jumper, etc.). These two openings can be reduced to one if it is located on the axis of symmetry of the support.
- the peak holder sector itself-comprises a base, the section of which by a plane passing through the axis of symmetry has the shape of a yoke open in the direction of the base of the support which engages and presses on the support, at its outer part and on one of its lateral faces; it is closed at one of the lateral ends for example, by a welded block and open at the opposite end.
- the peak holder sector is provided with holes or openings intended for its attachment to the wheel (or the drum), in particular, at least one complementary opening of one of the openings made in the support.
- the lateral faces can have any profile both in a diametral plane (perpendicular to the wheel axis) and in a tangential plane (perpendicular to a radius of the wheel on its outer surface), provided that the condition ⁇ ⁇ 90 ° be respected.
- the arrow indicates the direction of rotation of the wheel during work.
- the wheel (1) comprises a support (2) bounded by a flat face (3) and two lateral faces (4) in a radial plane, which is joined to the wheel (1) by a weld (5).
- the support is provided with two circular holes (6) symmetrical with respect to the axis of symmetry (7) of the support (2).
- the peak holder sector (8) comprises a base having the shape of a yoke closed on one side by a welded block (9); it presses on one of the sides (4) of the support (2) as well as on the flat face (3).
- the block (9) is fixed to the sector (8) by the weld bead (13).
- the base is pierced with two circular holes (10), one of which corresponds to the hole (6) of the support (2) which allows the removable connection of the sector (8) to the support (2) using a jumper elastic (11).
- the pick holder (12) is fixed to the sector (8) by the weld bead (14).
- the sector (8) can be mounted in one direction or the other on the support (2) by removing the jumper (11), by turning the sector (8) 180 ° around the axis of symmetry (7) and again putting the jumper in place (II).
- the front part of the sector (8) comprising the block (9) constitutes effective protection against abrasion of the support (2) which retains its geometry during work; it should also be noted that the force due to the work is supported directly by the support (2), the rider (11) having only a role of positioning and connection of the sector (8) to the wheel (1) ; the latter withstands practically no shearing force.
- the surface (3) can be different from a plane and can have any other configuration symmetrical with respect to the axis (7) in particular that of a cylinder sector, the axis of which coincides with that of the wheel (1 ), as shown schematically in (3 ') in Figure 1.
- the side faces may have any profile symmetrical to the axis (7) as shown in Figures la, lb, the angle a being ⁇ 90 °.
- the profile of the bearing faces (4) is either rounded (19, FIG. 2a), or chamfered (20, FIG. 2b), either bevel (21, Figure 2c), and symmetrical with respect to the axis (7).
- the sector can be fixed to the support by a split pin (15), which engages in a hole (16) tangent to the rear support face ( 4) of the support.
