Description

RIPPER SYSTEM TECHNICAL FIELD
This invention relates to engineering vehicles and in particular, to engineering vehicles comprising a front-end loading arrangement designed to perform a range of digging tasks. The invention provides an improved digging system for such vehicles. BACKGROUND TO INVENTION
Engineering vehicles with a front-end loading arrangement are used in a variety of applications. For example, in the building trade, front-end loaders are used by both the single-man building contractor and large scale construction companies for their respective digging tasks.
Similarly Government bodies and councils also use front-end loaders for their public works, such as in road construction and drainage and sewage repairs. The present invention provides advantages over the standard bucket digging systems attached to front-end loading engineering vehicles. In particular, the present invention greatly improves the digging capabilities and efficiency of such a vehicle, so much so, that a conventional backhoe attachment may not be required on the vehicle; since advantageously, the present invention can, in some situations, perform the function of the backhoe attachment. The present invention significantly reduces the operating time of the vehicle for a given digging operation and in turn greatly enhances the digging efficiency of the standard front-end loading bucket. SUMMARY OF INVENTION To this end the present invention provides a ripper system adapted to fit on a bucket assembly of a front-end loader portion of an engineering vehicle; said ripper system including at least one ripper means mounted on said front- end loader bucket assembly and adapted to be capable of gouging the earth during reverse motion of the said front-end loader bucket assembly. The present invention utilises the reverse motion of the front-end loader bucket assembly during digging operations to gouge and loosen the earth which is then dug up during the forward motion of the front-end loader bucket assembly. With known front-end loader arrangements this reverse motion of the front-end loader bucket assembly is not utilised as a digging motion. Thus the present invention provides a device which greatly assists in the digging and loading operations performed by the front-end loading bucket, without the need for extra attachments or machines, since the ripper system reduces the operating time and thus greatly enhances the digging efficiency of the standard front-end loading bucket.
In one possible form of the invention the ripper means of the ripper system may be attached directly to the bucket of the front-end loader bucket assembly. In another possible arrangement the ripper means may be attached to members of the bucket assembly adjacent the bucket. In further possible arrangement the ripper means may be mounted on a supporting member which is mounted on the bucket assembly.
It is preferable for the ripper system to be mounted on the rear of the front- end loader bucket assembly.
The ripper system may include a single ripper means or may include a plurality of ripper means. Where a plurality of ripper means are used these may be arranged to form an array of rippers which extend substantially across the width of the bucket assembly. The ripper means may be movably mounted relative to the bucket assembly. In such an arrangement the ripper means may be capable of translational and/or rotational movement relative to the bucket assembly so that during a forward digging motion of the front-end loader bucket assembly the ripper means can move into a position so as to not impede the digging operation of the bucket assembly. One possible form of the invention may include a supporting member which is movably mounted on the bucket assembly and on which the ripper means are mounted.
Alternatively the ripper means may be in fixed relation to the bucket assembly. In this arrangement it is preferable for the ripper means to be positioned on the bucket assembly such that the ripper means does not impede the digging operation of the bucket assembly. The ripper means may be integrally formed in the bucket assembly. Alternatively the ripper means may be permanently fixed to the bucket assembly. In such an arrangement the ripper means could be welded to the front-end loader bucket assembly. In another possible arrangement the ripper means could be releasably engagable with the bucket assembly. In such an arrangement the bucket assembly could be designed to receive the ripper means and the ripper means be locked in place on the bucket assembly by means of a retaining pins or clips. This arrangement provides the additional advantage of enabling one or more of the ripper means to be quickly and easily replaced should they become damaged or worn. BRIEF DESCRIPTION OF ACCOMPANYING DRAWINGS This invention will be better understood with reference to the following description of the features of a number of preferred embodiments of the invention. Reference is made to the accompanying drawings in which:
Figure 1 illustrates the front-end loader portion of an engineering vehicle incorporating one preferred embodiment of the ripper system, with the ripper system shown in the "active" position.
Figure 2 illustrates the ripper system depicted in Figure 1 , with the ripper system in the stored or "inactive" position.
Figure 3 illustrates the ripper system depicted in Figure 1 gouging the earth. Figure 4 illustrates the ripper system depicted in Figure 1 positioned on the rear of the front-end loader bucket assembly and applied across the width of the bucket assembly.
Figure 5 illustrates the front-end loader portion of an engineering vehicle incorporating a second preferred embodiment of the ripper system. Figure 6 illustrates the ripper system shown in Figure 5 gouging the earth;
Figure 7 illustrates the ripper system of Figure 5 positioned on the rear of the front-end loader bucket assembly and applied across the width of the bucket assembly. DESCRIPTION OF PREFERRED EMBODIMENTS
Figure 1 generally indicates the front-end loader bucket assembly 11 and a preferred embodiment of the ripper system 20. Figure 1 illustrates an individual ripper 20 in digging position and, as is noted due to the shape and arrangement of the ripper, the ripper 20 can move out of the way when the front end loader bucket assembly 11 moves in the forward direction. Figure 2 illustrates the ripper in a stored position and generally the ripper or rippers 20 are maintained in this position when the engineering vehicle is not being used to perform digging operations. In order to maintain the ripper 20 in the stored position a retaining pin 21 is inserted into the accommodating hole. In order to allow the rippers to fall into the digging position, the retaining pins are removed. In operation, when the front-end loader bucket assembly moves backwards, such as when the engineering vehicle is in reverse, the ripper 20 rests against the bucket assembly and the earth is gouged and dug up; reference is made to Figure 3, where the arrow indicates the direction of motion of the front-end loader bucket assembly during this operation.
When the front-end loader bucket assembly moves in a forward motion, such as when the engineering vehicle moves forward to scoop up earth with the bucket, the ripper 20 automatically lifts up by rotating about the pivot point 22, thus allowing the bucket to pick up the dirt and rock material 30 which has been broken up by the ripper or rippers 20 during the reverse motion.
Figure 4 illustrates the ripper system of Figure 1 where the ripper system includes an array of rippers 20 located on the rear of the front-end loader bucket assembly and extending across the width of the bucket assembly.
Figure 5 generally depicts a second preferred embodiment of the ripper system. In this form the rippers 20 are in fixed relation to the bucket assembly 11. The rippers 20 may be integrally formed in the bucket assembly. Alternatively the rippers 20 may be permanently fixed to the bucket assembly 11. In such an arrangement the rippers 20 could be welded to the rear portion of the front-end loader bucket assembly. In another possible arrangement the rippers 20 could be releasably engagable with the bucket assembly 11. In this an arrangement the bucket assembly could be designed to receive the rippers and the rippers be locked in place on the bucket assembly by means of a retaining pins or clips. This arrangement provides the additional advantage of enabling one or more of the rippers to be quickly and easily replaced should they become damaged or worn.
Figure 6 depicts the preferred embodiment of the ripper system of Figure 5 in operation. When it is desired to gouge the earth 30 with the rippers 20, such as at the completion of a forward digging motion, the bucket assembly is rotated clockwise until the rippers 20 are in a vertical or near vertical position and the bucket assembly is lowered so as to bring the rippers 20 into engagement with the earth 30 as depicted in Figure 6. Upon reverse motion of the front-end loader bucket assembly as indicated by the arrow, the rippers 20 gouge the earth 30 thereby facilitating easier digging and scooping of the earth on the subsequent forward motion of the bucket assembly.
Figure 7 illustrates the ripper system of Figure 5 in which an array of rippers 20 are located on the rear of the front-end loader bucket assembly and span the width of the bucket assembly 11.
Thus it can be appreciated that the ripper system disclosed herein greatly enhances the digging efficiency of the standard front-end loading bucket.
