DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0019] Referring to the Figures, a reel assembly 10 for use with a feed mixer 12 has a central shaft 14 that extends through and between end walls 16 of a mixing tank 18. The mixing tank 18 has a first mixing chamber 19 partially separated from a second chamber 20 or auger trough. A pair of augers 22 and 24 are stacked within the auger trough 20. The central shaft 14 and augers are rotatably driven by a drive means (not shown) that is well known in the art.

[0020] The central shaft 14 has a first end 26 and a second end 28. Connected to the central shaft 14 are a plurality of support plates 30. Any number of support plates 30 may be used but in a preferred embodiment support plates 30 are connected to ends 26 and 28 and a third support plate 30 is connected to the center of the central shaft 14.

[0021] The support plates 30 have a plurality of support arms 32 that extend radially from the central shaft 14 to an outer end 34. Each support plate 30 can have any number of arms 32 and in a preferred embodiment the support plates 30 at ends of 26 and 28 each have three support arms 32 and the center support plate 30 has six support arms 32. In the preferred embodiment the support plates 30 on each end 26 and 28 are offset so that the support arms 32 are not aligned with one another.

[0022] Extending between the support arms 32 of the support plates 30 at the ends of 26 and 28 and the support arms 32 of the central support plate 30 are reel bars 36. The reel bars 36 are connected to the support arms 32 with a torsion spring assembly 38.

[0023] While the torsion spring assembly 38 is of any size, shape, or structure, in one example the assembly includes a connecting member 40 having a mounting plate 42 and a plurality of walls 44 that extends outwardly from plate 42 to form a hollow chamber 46. In the example shown in the Figures, the walls 44 form a square shape. The mounting plate 42 is connected to the outer end 34 with bolts or rivets.

[0024] Disposed within the hollow chamber 46 is at least one compression member 48 and a connecting block 50. The compression member 48 are of any size, shape, and structure and in the example shown the compression members 48 are formed as cylinders. The compression members 48 also are made of any compressible material and in this embodiment are made of a compressible rubber. The connecting block 50 is of a shape that is complimentary to the shape formed by the cavity walls 44. Disposed within the connecting block 50 are a plurality of bores 52.

[0025] Attached to each reel bar 36 are a pair of spaced connecting arms 54. The connecting arms 54 extend outwardly from the reel bars and engage an outer end of the connecting member 40. The connecting arms 54 have a plurality of holes 56 that align with the bores 52 of the connecting block 50. Bolts 58 extend through holes 56 and into bores 52 to connect the reel bar 36 to the support arm 32.

[0026] The support arms 32 also have a wedge 60 between the outer end 34 and the central shaft 14. The wedges 60 are positioned to funnel feed ingredients toward the reel bars 36 and away from the support arms 32.

[0027] In operation, the reel assembly 10 rotates in a particular direction such that the reel bars 36 sweep along the bottom of the mixing chamber 19 and lift feed upwards towards the secondary chamber 20. As the reel assembly 10 rotates the reel bars 36 engage the feed ingredients causing the feed to tumble in combination with the auxiliary movement to the augers 22 and 24. When feed material becomes wedged between the reel bar 36 and the wall of chamber 19, the bar 36 is deflected backwards in the direction opposite of the rotation of the reel assembly 10 providing relief for the feed material to clear. More specifically, when feed material becomes wedged, force or pressure is applied to the reel bar 36. This force is transferred from the reel bar 36 through the connecting arms 54 to bolts 58 to connecting block 50 where the force compresses compression member 48 is covered by the connecting arms 54 to reduce feed material encroachment into chamber 46 to plug or clog the torsion spring assembly 38 or corrode the assembly.

[0028] In an alternative embodiment, instead of using at least one compression member 48 in the torsion spring assembly 38 a pourable, elastic, setting compound 62 is used to fill the voids around the connecting block 50 in the hollow chamber 46. The voids are entirely filled with the compound 62, or alternatively, the compound 62 fills the void around removable inserts 64. Once removed, the void left from the inserts 64 facilitates compression of the compound 62. The pourable compound 62 provides a torsional spring action through compression and expansion as the connecting block 50 rotates within the hollow chamber.

[0029] In yet another example of a torsion spring assembly 38, a bracket 66 is attached to the mounting plate 42. The bracket 66 has a mounting pad 68, an inner 70 and outer 72 side walls, and an angled top 74. Connected to the mounting pad 68 within the bracket 66 is a compression member 76. The compression member 76 is of any type and preferably is made of rubber or other elastic composite. A connecting arm 54 is rotatably mounted within the bracket 66 and positioned to engage and compress the compression member 76 against the mounting pad 68. More specifically, the connecting arm 54 is formed and positioned to compress the compression member 76 when the connecting arm 54 is rotated.

[0030] Therefore, a reel assembly 10 has been disclosed that at the very least meets all the stated objectives.
