20110293394 | Scraping, Hauling and compacting machine - A device for gathering and removing chicken litter from chicken houses and for compacting the litter onto a compost pile. The scraper, hauler and compacter cleans and levels the floor of a chicken house as the scraper is being pulled by a tow vehicle such as a small tractor. A tiltable container is filled with the litter as scraping is done. When the container is full, the apparatus is towed to a compost pile where the scraper is either backed onto the pile or can be pulled up onto the pile. The container is tilted and the tailgate is opened. The apparatus is configured such that the wheels are in the rear and when the container is tilted into an unloading position with the tailgate hanging down in front of the wheels, the tailgate levels the litter out as the apparatus is moved forward. The wheels compress the litter onto the compost pile. Therefore, emptying, leveling and compacting the litter are all accomplished in one fluid motion, leaving the compost pile level and ready to receive another load immediately. | 12-01-2011 |
