Abstract

A tractor having a front end loader has a bucket with tines attached to the underside of the bucket. The front end loader is used to raise/lower and tilt the bucket in a conventional fashion in order to position the tines where they can gather trash by driving the tractor forwardly towards the trash. The trash can be picked up by first tipping the front end of the bucket up, which tips the bottom of the tines up as well. Secondly, the bucket, tines and trash can then be lifted using the front end loader. Thirdly, the tractor can then be driven to a place where the trash is to be dumped and fourthly, the bucket can be tipped so the front end of the bucket and thereby the bottom of the tines are tipped backwardly and upwardly to cause the trash to fall out of the tines.

Description

TECHNICAL FIELD

This invention relates generally to devices for collecting trash and more particularly to one that can be used in combination with a tractor with a front end loader.

BACKGROUND

Front end loaders on tractors are useful for many well know purposes. However, when trying to gather up branches from trees that are on the ground from storms, or gathering debris, such as building parts, from tornados or strong winds, front end loaders are difficult to use because the trash/limbs tend to fall out of the bucket portion of such front end loader. So only very small loads of trash are able to be moved using a conventional front end loader for limbs and trash produced from storms or the like.
Teeth attached to the bucket portion of a front end loader to overcome the aforementioned problem are shown in U.S. Pat. No. 5,425,189 to Anderson et al. and U.S. Pat. No. 8,069,591 to Dunn, for example, which are incorporated herein by reference in their entirety. The Anderson et al. device has teeth on the top of the bucket of a front end loader which does not adequately solve the aforementioned problem. The Dunn device has an extra set of moveable teeth like a grapple which makes it more expensive to manufacture and more complicated to use.
U.S. Pat. No. 6,990,758 to Holmes et al., which is also incorporated herein by reference in its entirety, shows teeth attached to the bottom of an excavator bucket for a similar purpose. But having the teeth on the bottom of an excavator bucket requires movement of the excavator bucket using articulated arms which make the process slow.
Accordingly, an attachment to a bucket of a front end loader which is inexpensive to make and easy to use is needed for efficiently gathering trash.

DETAILED DESCRIPTION

Referring now to the drawings, wherein like reference numerals indicate identical or similar parts throughout the several views, FIGS. 1-6 show a trash gathering and moving apparatus 10 constructed in accordance with a preferred embodiment of the invention.
The trash rake apparatus 10 includes a tractor 11 having a front end loader apparatus 12 attached thereto. The front end loader 12 shown in FIGS. 1-6 includes a bucket 13 pivotally attached at pivot 14 a to an arm 14, which is in turn pivotally attached at pivot 14 b to another arm 16 which is pivotally attached to the tractor 11 at member 11 a, which is rigidly attached to the tractor 11 frame.
A first hydraulic cylinder 15 is pivotally attached at one end at pivot 15 a to the top of the bucket 13 and at the other end at pivot 15 b thereof to the arm 16. The arm 16 is pivotally attached to member 11 a at pivot 16 a. A second hydraulic cylinder 17 is pivotally attached at pivot 17 a at one end to the arm 16 and at pivot 17 b/14 b, the other end thereof being pivotally attached to the tractor 11 at pivot 17 a. This can be a typical arrangement for attachment of front end loaders to tractors but it will be understood to those skilled in this art that other attachments of front end loaders to tractors are possible and those other arrangements are intended to be covered within the scope of the appended claims.
A tine apparatus 20 is attached to the bottom of the bucket 13 as shown in FIGS. 1-6. FIGS. 1 and 2 show that each tine is attached at the top thereof to a bracket 22 that is rigidly bolted to the bottom of the bucket 3 by nut and bolt fasteners, though the bracket 22 could be fastened in other ways to the bucket 13 or the tines 21 could be attached in other ways to the bottom of the bucket 13. The tines 21 are preferably made of spring steel so they will bend rearwardly when the tractor 11 is moving forward and the bottom tips of the tines 21 are scraping along the ground as shown in FIG. 3, but the tines 21 will return to their original shape shown in FIGS. 1, 2 and 5 once such forces are no longer present on the tines 21.
In operation, the apparatus 10 shown in FIG. 3 shows the tractor moving forwardly gathering up trash 18 on the ground in the tine apparatus as the tines 21 scrape along the top of the ground. Once the trash 18 has been gathered into the tine apparatus 20, the front end loader 12 is raised using hydraulic cylinder 17 to the FIG. 4 position and the bucket 13 is tipped rearwardly using hydraulic cylinder 15 to cause the trash in the tine apparatus to be held in a position so the tractor 11 can be driven to a place where the trash 18 is to be dumped without the trash 18 falling out of the tine apparatus 20.
Then the tractor 11 can be driven to a place where the trash 18 is to be dumped onto the ground as is shown in FIG. 5 whereupon the trash 18 is dumped onto the ground and with the front end loader being lowered using the hydraulic cylinder 16 and the bucket tipped forwardly using the hydraulic cylinder 15 so that the trash falls out of the tine apparatus 20 onto the ground. Alternatively, the tractor 11 could be driven to a trailer 19 as shown in FIG. 6, or to a truck bed, not shown, the tractor being stopped at the place where trash is to be dumped onto the trailer 19, with the front end loader 12 being still in a raised position but with the bucket 13 tipped forwardly so that the trash 18 falls out of the tine apparatus 20 onto the bed of a trailer 19.
It is noted that the rake attachment 20 is wider by the distance “x” than the bucket 13 as shown in the preferred embodiment of FIG. 1, but that it could be the same width as the bucket 13 or narrower than the bucket 13 if desired.
Those skilled in the art will recognize that a wide variety of modifications, alterations, and combinations can be made with respect to the above described embodiments without departing from the spirit and scope of the invention, and that such modifications, alterations, and combinations are to be viewed as being within the ambit of the inventive concept as expressed by the attached claims.
