Description
SLIP ON SHOVEL
FIELD OF THE INVENTION
This invention relates to a shovel for mounting on a conventional implement shank and more particularly to a mounting apparatus for mounting the shovel on the implement shank.
BACKGROUND
Ground working implements are typically mounted on conventional implement shanks of a cultivator using bolts. The bolts cannot be secured manually and thus require the use of tools for fastening. Consequently, mounting and removing the implements from' the implement shanks is an inconvenient and time consuming process.
SUMMARY
According to the present invention there is provided a shovel including a mounting apparatus for mounting the shovel on an implement shank. The mounting apparatus is particularly suited for mounting the high centre shovel of US
Patent 4,794,992 to Loch on a conventional implement shank.
According to the present invention there is provided a slip on shovel arranged to mount on a ground working implement shank, the shovel comprising:
a pair of elongate flanges diverging rearwardly and outwardly from a common longitudinal apex;
at least one channel member mounted on a rear face of the pair of elongate flanges such that the channel member and the pair of flanges form a collar arranged to receive the shank therethrough, the channel member having at least one aperture in a rearward face arranged to co-operate with a bolt hole extending through the shank;
a locking member arranged to be slidably received through each _2_ aperture and the corresponding bolt hole for securing the shovel to the shank, the locking member including resilient means mounted on an end thereof such that removal of the locking member requires deforming the resilient means.
There may be provided a pair of apertures in the rearward face of the channel member for co-operating with a pair of bolt holes extending through the shank.
The channel member may comprise a U-shaped channel having a pair of sides extending rearwardly from the respective flanges and a rearward member connected between the pair of sides and arranged to engage a rearward face of the shank.
Preferably a forward face of the shank engages an inner face of the pair of flanges such that there is defined an inner chamber therebetween for receiving an inner end of each locking member therein.
Preferably each locking member is in the form of a shaft having a head mounted at an outer end arranged to engage a rearward face of the channel member and resilient material mounted on an inner end arranged to engage an inner surface of the respective bolt hole wherein the resilient material may be in the form of a dowel extending transversely through the shaft near the inner end of the pin.
Preferably the shaft includes a first portion extending from the head and having a suitable diameter arranged to engage the inner surface of the respective bolt hole, a second portion of reduced thickness extending from the first portion and a third portion of reduced thickness extending from the second portion. In this arrangement the dowel preferably extends through the second portion of the shaft at a location adjacent to the third portion.
The third portion of the shaft is preferably thicker than the second portion of the shaft and narrower than the first portion of the shaft. In this arrangement a combined thickness of the second portion of the shaft and the dowel when the dowel is flexed adjacent the second portion is preferably less than a diameter of the bolt holes. Also a combined thickness of the third portion of the shaft and the dowel when the dowel is flexed adjacent the third portion is preferably greater than a diameter of the bolt holes. The dowel is thus more difficult to remove from the bolt holes than to insert into the bolt holes.
There may be provided clamp means mounted on the rearward face of the channel member for securing a material delivery tube thereon such that the material delivery tube extends along a rear face of the shank. When using the clamp means, the clamp means are preferably arranged such that a bottom end of the material delivery tube extends forwardly below a bottom end of the shank. An additional material delivery tube may extend through the inner chamber adjacent the rear face of the flanges.

DETAILED DESCRIPTION
Referring to the accompanying drawings, there is illustrated a slip on shovel generally indicated by the number 10. The slip on shovel 10 is similar to the high centre shovel described in US Patent No. 4,794,992 to Loch and includes a modified mounting apparatus 11 for mounting the slip on shovel 10 on a conventional implement shank 12.
The shank 12 comprises an elongated steel member of rectangular cross section extending downwards from a cultivator and curving forwards in a direction of travel of the cultivator as indicated by arrow 14. The slip on shovel 10 mounts on a forward face 16 of the shank 12.
The slip on shovel comprises an elongated length of steel angulated longitudinally to form a pair of flanges 18 one upon each side of a longitudinally extending apex 20 which forms the high centre of the shovel of the above cited US
Patent No. 4,794,992. The apex 20 is arranged to follow a forward arc similar to a forward curvature at a bottom end 22 of the shank 12.
When the slip on shovel 10 is mounted on the shank 12, a pair of front side edges 23 of the shank engage an inclined inner face 24 of the flanges 18.
A
triangular chamber 26 is thus defined between the forward face 16 of the shank the inner face 24 of the pair of flanges 18.
The mounting apparatus 11 is in the form of a U-shaped channel member 28 mounted on the inner face 24. The channel member 28 is spaced from and centrally located between opposing ends 29 of the shovel such that the shovel is symmetrical about an axis 30 intermediate the ends 29. The ends 29 are identical and thus reversible from top to bottom.
The channel member 28 includes a pair of sides 31 each extending rearwardly from the inner face of one of the flanges 18 and arranged to engage a side 32 of the shank. A rear member 34 is connected between the sides 31 of the channel member towards a rearward end of the sides 31 for engaging a rearward face 36 of the shank 12. The U-shaped channel member 28 co-operates with the inner face 24 to form a collar for slidably receiving the shank there through.
A pair of apertures 38 are located in the rear member 34 for co-operation with bolt holes 40 in the shank. The pair of apertures 38 are spaced apart and symmetrically located above and below the axis 30. The apertures 38 are spaced an appropriate distance so as to co-operate with a location of the bolt holes 40 in the shank.
A locking pin 42 is inserted through each aperture 38 for securing the shank within the channel member 28. The locking pin 42 is in the form of a bolt having a head 44 and a shaft 46. The shaft includes a first portion 48 extending from the head 44. The first portion 48 is of a diameter suitable for being slidably received within the bolt holes 40 while engaging an inner surface 50 of the bolt holes.
A second portion 52 of the shaft extends axially from the first portion opposite the head 44. The second portion 52 includes a pair of recessed and flattened sides 54 such that the second portion 52 is narrower than the first portion 48. An end 56 of the first portion 48 is thus tapered inwardly towards the second portion to accommodate the reduced width of the second portion.
A third portion 58 of the shaft extends axially from the second portion 52 opposite the head 44. The third portion also includes a pair of recessed and flattened sides 60 such that the third portion 58 is narrower than the first portion 48 yet wider than the second portion 52. An end of the second portion is thus tapered outwardly towards the third portion to accommodate the increased width of the third portion.
On each locking pin 42 a rubber dowel 64 is inserted through the sides 54 of the second portion 52 such that end portions 66 of the dowel extend outwards past each respective side 54. The dowel 64 is positioned adjacent the third portion 58 of the shaft. The dowel is resilient such that the end portions 66 may be flexed to lie against either the sides 60 of the third portion or the sides 54 of the second portion of the shaft 46.
As the locking pin 42 is inserted into one of the bolt holes 40 the dowel will flex such that the end portions 66 lie against the sides 54 of the second portion as shown in Figure 5. The diameter of the dowel is arranged such that when the end portions engage the sides 54 of the second portion, the thickness of both end portions 66 and the second portion 52 combined is slightly less or equal to the diameter of the bolt holes 40. The locking pin is thus easily inserted into the bolt hole 40 and through the co-operating aperture 38.
Once the locking pin 42 has been inserted as shown Figure 2 the head 44 of the bolt engages a rear face 68 of the rear member 34 surrounding the aperture 38. The first portion 48 of the shaft extends through the bolt hole 40 and supports axial loads. The second portion 52 and third portion 58 extend into the triangular chamber 26 such that the dowel 64 can return to an unflexed position.
As the locking pin 42 is removed from the bolt holes 40 the dowel will engage the forward face 16 of the shank and flex such that the end portions 66 lie against the sides 60 of the third portion as shown in Figure 6. The diameter of the dowel is also arranged such that when the end portions engage the sides 60 of the third portion, the thickness of both end portions 66 and the third portion 58 combined is slightly greater to the diameter of the bolt holes 40. The locking pin thus requires that sufficient force be applied in the direction the locking pin is to be removed that the rubber dowel is deformed in the process. The locking pins are thus more difficult _7_ to remove than to insert to ensure the pins remain engaged within the bolt holes during use of the shovel. Once the locking pin has been removed the dowel will return to its original shape.
The shovel 10 is thus easily mounted or removed onto the shank 12 of a cultivator. In order to mount the shovel 10, the shank 12 is inserted between the channel member 42 and the inner face 24 such that the bolt holes 40 are aligned with the co-operating apertures 38. The locking pin 42 is then manually inserted into each bolt hole to a position resembling Figure 2. The first portion 60 of the shaft will support any axial toads exerted between the shank 12 and the shovel 10. In order to remove the shovel 10, the locking pins 54 are manually pulled out of the bolt holes 40. The shovel 10 is then slidably removed from the shank 12 such that another ground working tool may be mounted on the shank.
In a further embodiment of the present invention the channel member 42 may be replaced by a pair of collars wherein each collar is mounted on a rear face of the shovel in alignment with one of the bolt holes 40. Each collar is arranged to receive the shank 12 there through and includes a pair of apertures arranged to co-operate with the bolt holes 40 of the shank. The locking pins 42 operate in a similar manner as the first embodiment.
In other embodiments of the present invention the shovel 10 may be modified to include wings or sweeps while retaining the use of the channel and locking pins for securing the shovel to the shank.
In an alternative embodiment as shown in Figures 7 and 8 there is provided a fertiliser delivery tube 80 and a seed delivery tube 82 attached to the previously described shovel 10.
The fertiliser delivery tube 80 extends through the triangular chamber 26 of the shovel adjacent to the inner face 24 of the flanges 18. The fertiliser delivery _8_ tube terminates at a bottom end 84 of the tube near the bottom end 22 of the shank 12.
The seed delivery tube 82 is secured to extend along the rearward face 36 of the shank 12 by a clamp 86. The clamp 86 includes an upper portion 88 and a lower portion 90. The upper portion 88 of the clamp 86 includes base member 92 welded to the rear face 68 of the channel member 28. A pair of side members 94 extend rearwardly from opposing sides of the base member 92 for receiving the seed delivery tube 82 therebetween. Each side member 94 includes a hook 96 at a rearward end which curves inwards and engages the seed delivery tube 82 for securing the tube within the clamp.
The lower portion 90 of the clamp extends from the upper portion 88 and has a cross section similar to the upper portion for securing the seed delivery tube therein. The lower portion 90 is inclined forwardly in relation to the upper portion 88 such that a bottom end 98 of the seed delivery tube 82 extends forwardly below the bottom end 22 of the shank.
When the shovel 10 is mounted on the shank 12 one of the locking pins 42 is inserted in the aperture near a top end of the channel member as in the previous embodiment. The seed delivery tube 82 is then secured into the upper and lower portions of the clamp 86 such that the tube engages the head 44 of the locking pin for further securing the locking pin within the shank.
While a few embodiments of the present invention have been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention. The invention is to be considered limited solely by the scope of the appended claims.
FIELD OF THE INVENTION
This invention relates to a shovel for mounting on a conventional implement shank and more particularly to a mounting apparatus for mounting the shovel on the implement shank.
BACKGROUND
Ground working implements are typically mounted on conventional implement shanks of a cultivator using bolts. The bolts cannot be secured manually and thus require the use of tools for fastening. Consequently, mounting and removing the implements from' the implement shanks is an inconvenient and time consuming process.
SUMMARY
According to the present invention there is provided a shovel including a mounting apparatus for mounting the shovel on an implement shank. The mounting apparatus is particularly suited for mounting the high centre shovel of US
Patent 4,794,992 to Loch on a conventional implement shank.

DETAILED DESCRIPTION
Referring to the accompanying drawings, there is illustrated a slip on shovel generally indicated by the number 10. The slip on shovel 10 is similar to the high centre shovel described in US Patent No. 4,794,992 to Loch and includes a modified mounting apparatus 11 for mounting the slip on shovel 10 on a conventional implement shank 12.
The shank 12 comprises an elongated steel member of rectangular cross section extending downwards from a cultivator and curving forwards in a direction of travel of the cultivator as indicated by arrow 14. The slip on shovel 10 mounts on a forward face 16 of the shank 12.
The slip on shovel comprises an elongated length of steel angulated longitudinally to form a pair of flanges 18 one upon each side of a longitudinally extending apex 20 which forms the high centre of the shovel of the above cited US
Patent No. 4,794,992. The apex 20 is arranged to follow a forward arc similar to a forward curvature at a bottom end 22 of the shank 12.
When the slip on shovel 10 is mounted on the shank 12, a pair of front side edges 23 of the shank engage an inclined inner face 24 of the flanges 18.
A
triangular chamber 26 is thus defined between the forward face 16 of the shank the inner face 24 of the pair of flanges 18.
The mounting apparatus 11 is in the form of a U-shaped channel member 28 mounted on the inner face 24. The channel member 28 is spaced from and centrally located between opposing ends 29 of the shovel such that the shovel is symmetrical about an axis 30 intermediate the ends 29. The ends 29 are identical and thus reversible from top to bottom.
The channel member 28 includes a pair of sides 31 each extending rearwardly from the inner face of one of the flanges 18 and arranged to engage a side 32 of the shank. A rear member 34 is connected between the sides 31 of the channel member towards a rearward end of the sides 31 for engaging a rearward face 36 of the shank 12. The U-shaped channel member 28 co-operates with the inner face 24 to form a collar for slidably receiving the shank there through.
A pair of apertures 38 are located in the rear member 34 for co-operation with bolt holes 40 in the shank. The pair of apertures 38 are spaced apart and symmetrically located above and below the axis 30. The apertures 38 are spaced an appropriate distance so as to co-operate with a location of the bolt holes 40 in the shank.
A locking pin 42 is inserted through each aperture 38 for securing the shank within the channel member 28. The locking pin 42 is in the form of a bolt having a head 44 and a shaft 46. The shaft includes a first portion 48 extending from the head 44. The first portion 48 is of a diameter suitable for being slidably received within the bolt holes 40 while engaging an inner surface 50 of the bolt holes.
A second portion 52 of the shaft extends axially from the first portion opposite the head 44. The second portion 52 includes a pair of recessed and flattened sides 54 such that the second portion 52 is narrower than the first portion 48. An end 56 of the first portion 48 is thus tapered inwardly towards the second portion to accommodate the reduced width of the second portion.
A third portion 58 of the shaft extends axially from the second portion 52 opposite the head 44. The third portion also includes a pair of recessed and flattened sides 60 such that the third portion 58 is narrower than the first portion 48 yet wider than the second portion 52. An end of the second portion is thus tapered outwardly towards the third portion to accommodate the increased width of the third portion.
On each locking pin 42 a rubber dowel 64 is inserted through the sides 54 of the second portion 52 such that end portions 66 of the dowel extend outwards past each respective side 54. The dowel 64 is positioned adjacent the third portion 58 of the shaft. The dowel is resilient such that the end portions 66 may be flexed to lie against either the sides 60 of the third portion or the sides 54 of the second portion of the shaft 46.
As the locking pin 42 is inserted into one of the bolt holes 40 the dowel will flex such that the end portions 66 lie against the sides 54 of the second portion as shown in Figure 5. The diameter of the dowel is arranged such that when the end portions engage the sides 54 of the second portion, the thickness of both end portions 66 and the second portion 52 combined is slightly less or equal to the diameter of the bolt holes 40. The locking pin is thus easily inserted into the bolt hole 40 and through the co-operating aperture 38.
Once the locking pin 42 has been inserted as shown Figure 2 the head 44 of the bolt engages a rear face 68 of the rear member 34 surrounding the aperture 38. The first portion 48 of the shaft extends through the bolt hole 40 and supports axial loads. The second portion 52 and third portion 58 extend into the triangular chamber 26 such that the dowel 64 can return to an unflexed position.
As the locking pin 42 is removed from the bolt holes 40 the dowel will engage the forward face 16 of the shank and flex such that the end portions 66 lie against the sides 60 of the third portion as shown in Figure 6. The diameter of the dowel is also arranged such that when the end portions engage the sides 60 of the third portion, the thickness of both end portions 66 and the third portion 58 combined is slightly greater to the diameter of the bolt holes 40. The locking pin thus requires that sufficient force be applied in the direction the locking pin is to be removed that the rubber dowel is deformed in the process. The locking pins are thus more difficult _7_ to remove than to insert to ensure the pins remain engaged within the bolt holes during use of the shovel. Once the locking pin has been removed the dowel will return to its original shape.
The shovel 10 is thus easily mounted or removed onto the shank 12 of a cultivator. In order to mount the shovel 10, the shank 12 is inserted between the channel member 42 and the inner face 24 such that the bolt holes 40 are aligned with the co-operating apertures 38. The locking pin 42 is then manually inserted into each bolt hole to a position resembling Figure 2. The first portion 60 of the shaft will support any axial toads exerted between the shank 12 and the shovel 10. In order to remove the shovel 10, the locking pins 54 are manually pulled out of the bolt holes 40. The shovel 10 is then slidably removed from the shank 12 such that another ground working tool may be mounted on the shank.
In a further embodiment of the present invention the channel member 42 may be replaced by a pair of collars wherein each collar is mounted on a rear face of the shovel in alignment with one of the bolt holes 40. Each collar is arranged to receive the shank 12 there through and includes a pair of apertures arranged to co-operate with the bolt holes 40 of the shank. The locking pins 42 operate in a similar manner as the first embodiment.
In other embodiments of the present invention the shovel 10 may be modified to include wings or sweeps while retaining the use of the channel and locking pins for securing the shovel to the shank.
In an alternative embodiment as shown in Figures 7 and 8 there is provided a fertiliser delivery tube 80 and a seed delivery tube 82 attached to the previously described shovel 10.
The fertiliser delivery tube 80 extends through the triangular chamber 26 of the shovel adjacent to the inner face 24 of the flanges 18. The fertiliser delivery _8_ tube terminates at a bottom end 84 of the tube near the bottom end 22 of the shank 12.
The seed delivery tube 82 is secured to extend along the rearward face 36 of the shank 12 by a clamp 86. The clamp 86 includes an upper portion 88 and a lower portion 90. The upper portion 88 of the clamp 86 includes base member 92 welded to the rear face 68 of the channel member 28. A pair of side members 94 extend rearwardly from opposing sides of the base member 92 for receiving the seed delivery tube 82 therebetween. Each side member 94 includes a hook 96 at a rearward end which curves inwards and engages the seed delivery tube 82 for securing the tube within the clamp.
The lower portion 90 of the clamp extends from the upper portion 88 and has a cross section similar to the upper portion for securing the seed delivery tube therein. The lower portion 90 is inclined forwardly in relation to the upper portion 88 such that a bottom end 98 of the seed delivery tube 82 extends forwardly below the bottom end 22 of the shank.
When the shovel 10 is mounted on the shank 12 one of the locking pins 42 is inserted in the aperture near a top end of the channel member as in the previous embodiment. The seed delivery tube 82 is then secured into the upper and lower portions of the clamp 86 such that the tube engages the head 44 of the locking pin for further securing the locking pin within the shank.
While a few embodiments of the present invention have been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention. The invention is to be considered limited solely by the scope of the appended claims.
