Description:
MATERIAL HANDLING IMPLEMENT

FIELD OF THE INVENTION

The present invention relates to earth moving equipment and more particularly, relates to accessories suitable for use with an excavating machine.

BACKGROUND OF THE INVENTION

The use of earth moving equipment is well known in the art. Around the world, many different types of earth moving equipment are utilized in the construction of buildings, roads, bridges, and other like structures.

The earth moving equipment will go by a variety of names depending on the degree of specialization. Thus, such equipment may be known as a front end loader, compact excavator, backhoe, grader, scraper, etc. Frequently, many different pieces of equipment are utilized together on the same site in order to achieve a specific goal.

A very popular piece of equipment is that which is called a "compact excavator". These machines are very useful in excavating (normally in a location where access is limited). A problem in using such a piece of equipment is their inefficiency in moving large amounts of material at a single time. Frequently, contractors will utilize an additional piece of equipment such as a skid steer or loader to displace large amounts of material.

Most known track excavators include a digging bucket with a hydraulic levelling blade being located at one end thereof. The hydraulic levelling blade is attached to a hydraulic cylinder which supports the levelling blade, also known as a dozer blade, which is designed to lift and stabilize an excavator during digging. The lifting capacity of the hydraulic cylinder is substantial in order to manage the considerable weight capacities. The track excavator will have a digging bucket which is designed to form the conventional excavation function of the excavator.

Frequently, it is necessary to handle and transport the material excavated by the digging bucket. In order to store or transport this material, a second piece of equipment may be required. The material, after being transported, must then be disposed of.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an implement for a track excavator and which implement can store material being excavated as well as transporting such material and/or other materials as required.

According to one aspect of the present invention, there is provided a material handling implement comprising a container, the container having a base, first and second side walls, a rear wall, and a cradle secured to one of the side walls and rear wall, the cradle having first and second arms, each of the arms being movable between a first position wherein the base remains substantially horizontal when the container is lifted and a second position wherein the base extends diagonally when the container is lifted such that material may be discharged therefrom.

The implement of the present invention is designed to be used with a conventional track excavator. Track excavators are well known in the prior art and generally comprise an operator's booth mounted on a frame which is movable through the use of a pair of caterpillar threads on either side of the device. Mounted on the tractor is an excavating bucket or digging bucket. At one end of the tractor, there is provided a hydraulically powered levelling blade. The levelling blade is simply used for pushing earth or the like. It is hydraulically connected to move vertically as required. The excavating bucket functions through a hydraulic drive which can move the arms on which the bucket is mounted and thereby perform the excavating function. Such arrangements are well known in the art.

The implement of the present invention is preferably made of a steel material.

Suitable metallic materials are known in the art. The implement may be coated to withstand rusting thereof.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings in greater detail and by reference characters thereto, there is illustrated a material handling implement which is generally designated by reference numeral 10 and which forms a container for recovering material.

Material handling implement 10 includes a base 12 having a front edge 14, a rear edge 16, and a pair of side edges 18, 20. A vertically extending back wall 22 extends upwardly from rear edge 16 of base 12 while side walls 24, 26 extend upwardly from side edges 18, 20, respectively. Side walls 24 and 26 are also connected to back wall 22. It will be noted that side walls 24, 26 are substantially triangular in nature. This configuration helps in optimum loading of material handling implement 10.

Extending upwardly from a forward edge of side walls 24 and 26 are retaining members 28. Retaining members 28 comprise a member which extends upwardly from each of side walls 24, 26 at a point near where side walls 24, 26 meet front edge 14 of base 12. The retaining members are designed to retain any longitudinally extending member which may extend beyond the capacity of material handling implement 10— i.e. the distance between side walls 24, 26.

As may be seen from the drawings, there is provided a first bracket 30 and a second bracket 32 each of which are mounted on back wall 22. Brackets 30, 32 are designed to mount a cradle generally designated by reference numeral 34. Naturally, brackets 30, 32 could be connected to any appropriate surface. Cradle 34 includes first and second cradle arms 36 and 38. As each cradle arm 36, 38 is of a similar construction, only one will be described herein.

Cradle arm 36 has a first segment 40 which is contiguous with a second segment 42. First segment 40 and second segment 42 are substantially perpendicular to each other— the angle would generally range between 80 ° and 100°. A third segment 44 is contiguous with second segment 42 and again is substantially perpendicular thereto. In other words, generally the angle between second segment 42 and third segment 44 would be between 80° and 100° . A fourth segment 46 is contiguous with third segment 44 and forms an acute angle with respect thereto. Segment 42, third segment 44 and fourth segment 46 together define a recess generally designated by reference numeral 48. As may be seen in the drawings, recess 48 is such that when the arms are in an upward position (as shown in Figure 14), the bucket of the tractor will securely grip material handling implement 10 such that the same may be lifted without falling off. This is due to fourth segment 46 forming an acute angle with respect to third segment 44. It is also important that second segment 42 extends sufficiently rearwardly such that discharge of the contents from the material handling implement is accomplished. Thus, preferably, third segment 44 is located such that it is rearward of back wall 22.

Extending between brackets 30, 32 is a first horizontal member generally designated by reference numeral 50. First horizontal member 50 comprises an inner tube 52 and an outer tube 54. Each of inner tube 52 and outer tube 54 have apertures extending therethrough and are designed to be connected by pins 56. In this regard, the insertion of pins 56 will prevent relative rotation between inner tube 52 and outer tube 54. Since considerable force will be exerted, particularly around the apertures in outer tube 54, a reinforcing element may be formed thereon. This reinforcing element may comprise a washer or nut which is welded around the aperture in outer tube 54.

Cradle 34 also includes a second horizontal member 58 which comprises a solid rod 60 which is rotatably journalled in cradle arms 36, 38 at a distal end thereof.

As seen in the drawings, there are provided adjustable brackets 62 which retain a pair of C-shaped members 64, 66. As shown in Figure 13, C-shaped members 64, 66 are designed to receive the top of a dozer blade 68. In operation, material handling

implement 10 is designed to receive material therein. The material may be placed within material handling implement or container 10 by the tractor moving along and scooping up loose material. Alternatively, the shovel or bucket portion may be utilized to place material therein.

The relative rotation between inner tube 52 and outer tube 54 can be utilized to discharge material. Thus, removal of pins 56 will permit rotational movement of material handling implement 10 and material may be discharged therefrom. The material could be discharged all at once or could, for example, be spread in a layer of the same as the tractor would move while the discharge is occurring.

It will be understood that the above described embodiment is for purposes of illustration only and that changes and modifications may be made thereto without departing from the spirit and scope of the invention.
