The present invention relates generally to the field of fence post extractors. More specifically, the present invention relates to a fence post concrete extractor device that is comprised of a frame, a primary frame member, a winch assembly and a motor. The winch assembly penetrates the rotted fence post using a motor and expands inside, allowing it to remove the rotted fence post from the ground. In this manner, the device can be applied to automatically remove rotted fence posts from the ground, wherein an abundance of manual labor would otherwise be necessary. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices and methods of manufacture.
Fence posts are typically held in place by being cemented into the ground with a concrete base, which keeps the fence sturdy against wind and other factors. However, this base makes the removal of a fence post very difficult because it adds a great amount of weight to the fence post. If a fence post is rotted, the removal is even more difficult, as there may not be a sturdy point to hoist the fence post out of the ground without proper equipment. Additionally, an individual must dig deep into the ground, commonly three feet around the concrete base, and manually extract the post upwards out of the ground. This kind of work can be incredibly difficult, time-consuming, expensive, exhausting and potentially dangerous. As a result, serious injuries may occur when attempting to remove a cemented fence post out of the ground manually, with a shovel.
Therefore, there exists a long-felt need in the art for a fence post concrete extractor device. There also exists a long-felt need in the art for a device that minimizes the labor and effort required in extracting a previously cemented fence post from the ground. Further, there exists a long-felt need in the art for a fence post concrete extractor device that is easily transportable and powered by a single individual. In addition, there exists a long-felt need in the art for a device that reduces the likelihood of serious injuries, while attempting to remove a rotted fence post.
The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a fence post concrete extractor device. The device is comprised of a frame, a primary frame member, a winch assembly and a motor. The frame of the device is preferably sturdy, such that it can support the weight of the device and the concrete fence post. The device is also comprised of a winch assembly that can penetrate rotted fence posts and provide enough force to remove a concrete fence post from the ground via a cable powered by a motor. In this manner, the device can be used to easily remove rotted fence posts from the ground, wherein an abundance of manual labor would otherwise be necessary.
In this manner, the fence post concrete extractor device of the present invention accomplishes all the forgoing objectives and provides a means to remove a concrete fence post safely and efficiently. Further, the device may be easily transported, such that a single person may move and operate the device. In addition, the device removes many physical dangers, such as exhaustion, while removing concrete fence posts.
