The disclosure relates to scraper devices and more particularly pertains to a new scraper device for scraping dirt during excavation activities. The device includes a box scraper which has a plurality of teeth that are movably integrated into the box scraper.
The device includes an adjustment unit that is movably integrated into the box scraper for adjusting a height of the teeth. The adjustment unit is in communication with a control on the tractor for remotely adjusting the height of the teeth.
The prior art relates to scraper devices including a dirt scraper with a hydraulic piston for adjusting an angle of a blade on the dirt scraper. The prior art discloses a dirt leveling device that includes a plurality of chisels, a leveling blade and a pair of hydraulic actuators for adjusting the height of the chisels and the leveling blade. The prior art discloses a variety of farming implements that each includes a plurality of teeth and a hydraulic actuator for adjusting a height of the teeth. The prior art discloses a box scraper which includes a scraping blade and a hydraulic actuator for adjusting a height of the scraping blade.
An embodiment of the disclosure meets the needs presented above by generally comprising a box scraper that is attachable to a tractor for scraping dirt. A plurality of teeth is each movably disposed in the box scraper to dig into the dirt when the box scraper is drawn along the ground. Each of teeth is adjustable between minimum height and a maximum height. An adjustment unit is movably integrated into the box scraper and the adjustment unit is in mechanical communication with each of the teeth. The adjustment unit adjusts each of the teeth between the minimum height and the maximum height. Furthermore, the adjustment unit is in communication with a control on the tractor for actuating the adjustment unit to adjust the teeth between the minimum height and the maximum height.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The box scraper 12 includes a mounting bracket 30 which has a vertical member 32 extending upwardly from the box scraper 12 and a plurality of horizontal members 34 is perpendicularly oriented with the vertical member 32. Additionally, the mounting bracket 30 includes a pair of angled members 36 each angling between the vertical member 32 and the horizontal members 34. The vertical member 32 is attachable to an attachment point 38 on the tractor 14 for mounting the box scraper 12 to the tractor 14.
A plurality of teeth 38 is provided and each of the teeth 38 is movably disposed in the box scraper 12 to dig into the dirt 17 when the box scraper 12 is drawn along the ground 16. Each of teeth 38 is adjustable between minimum height and a maximum height. Each of the teeth 38 has an upper end 40 and a lower end 42, and each of the teeth 38 extends through a respective one of the slots 28 in the primary member 22. Moreover, the upper end 40 of each of the teeth 38 is spaced upwardly from the top side 24 of the primary member 22 and the lower end 42 of each of the teeth 38 is spaced downwardly from the bottom side 26 of the primary member 22.
An adjustment unit 44 is movably integrated into the box scraper 12 and the adjustment unit 44 is in mechanical communication with each of the teeth 38. The adjustment unit 44 adjusts each of the teeth 38 between the minimum height and the maximum height. Furthermore, the adjustment unit 44 is in communication with a control on the tractor 14 for actuating the adjustment unit 44 to adjust the teeth 38 between the minimum height and the maximum height. The adjustment unit 44 comprises a rod 46 that is rotatably mounted to the box scraper 12. The rod 46 is oriented to extend between the pair of lateral walls 20 of the scraper box and the rod 46 is rotatable about an axis extending between the lateral walls 20.
The adjustment unit 44 includes a first arm 48 has a first end 50 and a second end 52. The first end 50 of the first arm 48 is coupled to the rod 46 and the first arm 48 is centrally positioned between the pair of lateral walls 20 of the scraper box. The adjustment unit 44 includes a hydraulic piston 54 that has a primary end 56 and a secondary end 58. The primary end 56 is coupled to the vertical member 32 of the mounting bracket 30 and the secondary end 58 is coupled to the second end of the first arm 48.
The hydraulic piston 54 is elongated between the primary end 56 and the secondary end 58 when the hydraulic piston 54 is actuated into an extending condition. Conversely, the hydraulic piston 54 is shortened between the primary end 56 and the secondary end 58 when the hydraulic piston 54 is actuated into a retracting condition. The first arm 48 rotates the rod 46 in a first direction when the hydraulic piston 54 is actuated into the extending condition. The first arm 48 rotates the rod 46 in a second direction when the hydraulic piston 54 is actuated into the retracting condition. The hydraulic piston 54 is fluidly coupled to a hydraulic system 60 of the tractor 14 for controlling the hydraulic piston 54.
The adjustment unit 44 includes a plurality of second arms 62 that each has a first end 64 and a second end 66. The first end 64 of each of the second arms 62 is coupled to the rod 46 and each of the second arms 62 is aligned with a respective one of the teeth 38. The second end 66 of each of the second arms 62 is pivotally coupled to the respective tooth 38 at a point that is located adjacent to the upper end 40 of the respective tooth 38. Additionally, each of the second arms 62 is rotated upwardly when the rod 46 is rotated in the first direction such that each of the teeth 38 is lifted. Each of the second arms 62 is rotated downwardly when the rod 46 is rotated in the second direction such that each of the teeth 38 is lowered. Each of the second arms 62 may have a series of bends 68 such that the first end 64 is offset from the second end 66.
In use, the mounting bracket 30 is mounted to the attachment point 38 on the tractor 14 and the hydraulic piston 54 is fluidly coupled to the hydraulic system 60 of the tractor 14. In this way the hydraulic piston 54 can be controlled by a driver of the tractor 14. Thus, the driver can lower or raise the teeth 38 while the driver is operating the tractor 14. In this way the driver can continuously perform dirt 17 excavation work while also adjusting the height of the teeth 38.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
