Abstract
ABSTRACT OF THE DISCLOSURE
An improvement in a vertical screw cutter/mixer consisting of an inverted generally conical container and a vertical screw. The vertical screw is rotatably mounted within the container solely at its base. The improvement consists of a combination of elements. A spiral flight is provided on the screw consisting of a plurality of convolutions describing a truncated conical shape. Means is provided for mounting a plurality of blades to the screw such that they extend upwardly past the apex of the shaft of the screw. At least one of the blades is positioned adjacent a peripheral edge of an upper convolution of the flight such that a circular path is described by the peripheral blade which is substantially the same diameter as the upper convolution of the flight. Impaling fingers are positioned adjacent to the top of the container and extend inwardly. The impaling fingers are in substantially horizontal alignment with the upwardly extending blades.
The impaling fingers are movable between an extended position and a retracted position. In the extended position the fingers impede the speed of rotation of the bale to less than the speed of rotation of the screw whereupon the blades tear chunks of material from the bale.
In the retracted position the fingers release the bale whereupon the hale descends upon by force of gravity further into the container until obstructed by the upper convolution of the flight of the conical screw.

Description
63~
The present invention relates to a vertical screw cutter/mixer with a screw supported solely at its base.
5 BACKGROllND OF T~{E I~lVENTION
There are a number of vertical screw mixers in which the screw is supported solely at its base. However, this type of screw has never been successfully used in a cutting application, their use is presently restricted to~a mixing function; mixing material which is substantially precut.
In theory, a vertical screw supported solely at its base presents a number of potential advantages in a cutting application. There is no stationary top support against which material can become jammed. This jamming occurs with 15 top supported screws when material gets wedged between the top support and the flighting of the screw. It causes a bending of the top support and damage to the drive mechanism. In view of the potential for jamming, vertical screw cutterlmixers having top supports must be engineered to withstand the stresses which result from jamming. This results in increased costs of manufacture. In addition, the machines have increased weight which can be a factor in mobile applications.
A recent example of an attempt to use a vertical screw supported solely at its base in a cutting application is illustrated in United States patent 5, 020/ 918 which issued to To Faccia in 1991. The Faccia patent can be used to illustrate some of the problems involved. The Faccia patent discloses a stand alone screw having a plurality of short blades extendin~ upwardly from the top of the shaft of the screw. In theory, the blades are intended to shred material. In practise, a bale of material merely becomes impaled on the blades and rotate at substantially the same speed as the screw. The convolutions of the flight of the screw serve to move material upward, therefore, a bale of material resting on the flighting of the screw is continually lifted and maintains a static position at the top o~ the container.
~0~6i30 SUMM~RY OF THE INVE~TION
What is required is a vertical screw cutter/mixer with a screw supported solely at its base which is capable of cutting large bales of material.
According to the present invention there is provided an improvement in a vertical screw cutter/mixer consisting of an inverted generally conical container and a vertical screw. The vertical screw is rotatably mounted within the container solely at its base. The improvement is comprised of a combination of elements. A spiral flight is provided on the screw consisting of a plurality of convolutions describing a truncated conical shape. Means is provided for mounting a plurality of blades to the screw such that they extend upwardly past the apex of the shaft of the screw. At least one of the blades is positioned adjacent a peripheral edge of an upper convolution of! the flight such that a circular path is described by the peripheral blade which is substantially the same diameter as the upper convolution of the flight. Impaling fingers are positioned adjacent to the top of the container and extend inwardly.
The impaling fingers are in substantially horizontal alignment with the upwardly extending blades. The impaling fingers are movable between an extended position and a retracted position. In the extended position the fingers impede the speed of rotation of the bale to less than the speed of rotation of the screw whereupon the blades tear chunks of material from the bale. In the retracted position the fingers release the bale whereupon the bale descends upon the screw.
With the vertical screw cutter/mixer as described is suited for cutting 2000 pound round bales of hay in agricultural applications and similar sizes of bales in garbage processing applications. The impaling fingers impede the rotation of the bale to permit an effective cutting action by the upwardly extending blades. Having at least one of the blades positioned adjacent t,he peripheral edge of the upper flight in combination with the truncated 2~S~6~
conical shape of the ver-tical screw, ensures that the blades remove enough material from the bale to permit the bale to descend further into the container without becoming "hung up" on the upper flight. The impaling fingers are alternately extended and retracted as the bale is dispersed into the container. In the extended position the impaling fingers hold the bale to resist rotational and upward movement to allow further penetration of the upper blades.
In the retracted position the weight of the bale causes the bale to descend further into the container past the upper convolu-tion of the ~runcated conical screw.
BRIEF DESCRIPTION OF THE D~AWINGS

~IGURE 1 is a section view of a vertical screw cutter/mixer constructed in accordance with the teachings of the present invention.
~IGURE 2 is top plan view of the vertical screw cutter/mixer illustrated,in FIGURE 1.
~IGURE 3 is a section view of an alternate embodiment vertical screw cutter/mixer constructed in accordance with the teachings of the present invention.

~ETAILED DE5CRIPTIO~ OF T~E PREFERRED ~M~ODI~E~T
The preferred embodiment, a vertical screw cutter/mixer generally identified by reference numeral 10, will now be described with reference to FIGURE~ ~ and 2.
The present invention is an improvement in vertical screw cutter/mixer 10. Those elements of vertical screw cutter/mixer 10 which are known in the prior art are an inverted conical container 12 and vertical screw 14.
Vertical screw 14 has a shaft 16 with a base 18 and an apex 20. Vertical screw 14 is supported solely at base 18 and is rotatably mounted within container 12. The means for 4 ~5~
rotatably mounting base 18 does not form part of this invention and will not be further described.
The improvement lies in modifications which have been made to vertical screw cutter/mixer 10 to enable vertical screw cutter/mixer 10 to accommodate large bales of material 13. Bales of material 13 are encountered in agricultural applications and garbage processing applications. For example, cattle operations cut 2000 pound round bales of hay and mix the hay with other agricultural produce to provide a cattle feed that is properly balanced in nutrients. In order to function in combination with other elements which will be hereinafter further described screw 14 must take a particular form.
Screw 14 must have spiral flight 22 which generally describes a truncated conical shape. Flight 22 has a plurality of convolutions; three convolutions are illustrated in FI&URE 1, which for the purpose of this description shall be described as an upper convolution 24, and lower convolutions 26 and 28. Upper convolution 24 is positioned immediately adjacent apex 20 of shaft 16 of screw 14. Two types of blades are secured to screw 14.
Blades 30 extend radially from flight 22. Blades 32, 34, 36, and 38 extend upwardly from upper convolution 24 past apex 20. As is illustrated in FIGU~E 2, each of blades 32, 34, 36, and 38 is positioned a different radius from shaft 16. The result is that blades 32, 34, 36, and 38 describe a series of concentric circles. It should be noted that blade 38 is positioned adjacent a peripheral edge 40 of upper convolution 24 of flight 22, such that the circular path described by blade 38 is substantially the same diameter as upper convoiution 24. Impaling fingers 42 are positioned adjacent to a top edge 44 of container 12 and extend inwardly. Impaling fingers 42 are in substantially horizontal alignment with the blades so as to cooperate with them. Impaling fingers 42 are movable between an extended position and a retracted position by means of hydraulic actuators 46. A further set of impaling fingers ~5~6~(~
47 are positioned in substantial horizon-tal alignment with lower convolution 26. Hydraulic actuators 46 and associated controls are known in the art, do not form part of the invention and will therefore not be further described.
The use and operation of-the improvements in vertical screw cutter/mixer 10 will now be described in relation to FI~UR~S 1 and 2. In the agricultural example previously referred to, a 2~00 pound round bale 13 is placed upon top edge 44 of container 12 by means of a tractor with a front end loader (not shown). Initially, bale 13 become~ impaled upon blades 32, 34, 36, and 38 and is held up by apex 20 o~
shaft 16 and upper convolution 24 of flight 22. In this position bale 13 rotates at substantially the same speed as shaft 16, and is continually being lifted upwards by flight 22. Impaling fingers 42 are then moved to an extended position by means of hydraulic actuators 46. In the extended position impaling fingers 42 impede the speed o~
rotation of the bale to less than the speed of rotation of screw 14 whereupon blades 32, 34, 36, and 38 tear chunks 15 out of bale 13. By virtue of thè positioning of blade 38 on the peripheral edge 40 of upper convolution 24 of flight 22, sufficient material is removed from bale 13 to provide clearance for upper convolution 22. Impaling fingers 42 are then moved to a retracted position by means of h~draulic actuators 46. In the retracted position impaling fingers 42 release bale 13 whereupon bale 13 descends into container 12 until its descend is impeded by upper convolution 22 of screw 14. As previousl~ mentioned, the truncated conical shape of screw 14 is of importance in leaving sufficient room for bale 13 to descend. Impaling fingers 42 are alternatively moved between an e~tended position and a retracted position until bale 13 has descended pa~t upper convolution of screw 14. Once bale 13 descends ~ar enough into container 12, blades 30 are also able to contr:ibute to the cutting of bale 13. In order to prevent chunks 15 from circulating wi-thout being cut, lower impaling fingers 47 are provided.
The alternate embodiment, a vertical screw cutter/mixer generally identified by reference numeral 100, will now be described with reference to F~G~ES 3 and 4.
The components of vertical screw cutter/mixer 100 are identical in most respects to the components of vertical screw cutter/mixer 10 previously described. For that reason only the differences will be further described.
Vertical screw cutter/mixer 100 illustrates an alternate blade mounting means. In vertical screw cutter/mi~er 10 the means of mounting blades 32, 34, 36, and 38 was to secure them to upper convolution 24 of spiral flight 22.
With vertical screw cutter/mixer 100 the means for mounting a plurality of blades to screw 14 is a blade support 102.
Referring to FIGURES 3 and 4, a plurality of blades 104, 105, 106, and 107 are secured to blade support 102. Blade support 102 is, in turn, secured transversely to shaft 16 adjacent apex 20 of screw 14. The blades are spaced radially from shaft 16 at intervals along blade support 102. Blade support 102 rotates with shaft 16 of screw 14, and when it does so the path of the blades describè a series o~ concentric circles. Blade 104 is positioned adjacent to peripheral edge 40 of upper convolution 24 of spiral flight 22. By virtue of the positioning of blade 104 adjacent peripheral edge 40 of upper convolution 24 of flight 22, a sufficient portion of the bale is torn away to prevent the bale from becoming hung up on upper convolution 24 of flight 22.
It will be apparent to one skilled in ths art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention.
