172799500 | TOWED SCRAPER WITH GROUND SUPPORT WHEELS | 7 |
20080230244 | Apparatus, system and method for moving a scraping device - An apparatus, system and method for moving a scraping device are provided. The scraping device has a frame, a blade attached to the bottom of the frame, a tongue attached to a front end of the frame and a beam attached to a back end of the frame. Tires are connected to the beam. The scraping device has a front lift mechanism at the front end of the frame and/or a rear lift mechanism at the back end of the frame. The front lift mechanism has a front cylinder connected to the tongue and the front end of the frame. The rear lift mechanism has a rear cylinder attached to the back end of the frame. Movement of the front cylinder and the rear cylinder results in raising and/or lowering of the corresponding ends of the frame of the scraping device. Raising and/or lowering of the front end and/or the back end of the frame adjusts the angle of the frame relative to the ground, adjusts the angle of the blade relative to the ground and/or adjusts the ground clearance of the scraping device. | 09-25-2008 |
20080296033 | Road-drag - A road drag for medium and heavy grading projects is provided. The road drag includes a pair of side members and front, center and rear transverse bars that define a rectangular shaped platform. A V-member is disposed adjacent each corner of the platform and steel blades are attached to a first arm of each of the V-members in a downward direction. A center V-member is further attached to the center bar. Steel blades are further attached to ends of the center V-member in a downward direction. A tail board is secured to a pair of extensions that extend from the rear bar of the platform that defines a rear section. The rear section includes means to prevent the tail board from bouncing or hopping during application in order to better distribute material during use. The road drag further includes an axle and preferably dual wheels near or adjacent the tail board. The road drag further includes a front end that extends from the front bar of the platform with attaching means that is hitched to the back of a vehicle. The front end preferably includes a leveling means to raise and lower the platform for transport and work applications. | 12-04-2008 |
20090095496 | WALKING BEAM AND TIRE SYSTEM FOR AN EARTHMOVING SCRAPING DEVICE - An earthmoving scraping device has a bowl-shaped frame with walls and a frame floor that define an interior for transporting material and a walking beam system for the rear wheels thereof that includes a suspension arm pivotally connected between the back end of the frame and a beam, the beam having first and second axles on separate sides of the beam. Connected to the axles is a tire system that includes a cylindrical metal rim with an outer surface and a plurality of solid tire segments, each of the tire segments having at least one track that is connected to a mounting plate, the mounting plates being circumferentially positioned adjacent to the outer surface of the rim. | 04-16-2009 |
20090188685 | Soil Spreading Scraper Device - A soil spreading scraper device comprises a cutting blade for cutting a top layer of soil from the ground, a kicker for throwing the cut soil rearward from the cutting blade, and an impeller member rotatable within a plane of rotation extending upward and rearward from the cutting blade for capturing the soil thrown by the kicker and spreading the cut soil generally radially outward relative to an axis of rotation of the impeller. A gearbox which receives power from a power takeoff of a towing vehicle directly drives the rotation of the impeller member in the preferred embodiment. The blades of the impeller members may include recessed portions adjacent the impeller axis in some embodiments to encourage soil being received in the impeller member even at higher rates of rotation, for example in the range of 250 to 320 RPM. | 07-30-2009 |
20090194303 | Height and Gradient adjustment system - A height and gradient adjustment system is disclosed for raising, lowering, leveling, and changing a gradient, especially the gradient of implements. The height and gradient adjustment system enables independent height adjustment of each side, right or left, of the implement. | 08-06-2009 |
20150361639 | ADJUSTABLE EARTH SHAPING BLADE AND EARTH SHAPING APPARATUS - An adjustable earth shaping blade comprises a center section and at least one side section pivotally attached to the center section at an oblique angle. The side section may be moved forwards or backwards in order to change the profile of the contacting edge of the adjustable earth shaping blade. | 12-17-2015 |
20160194853 | Split Walking Beams for Raising and Lowering Respective Sides of a Vehicle or Implement Frame to Control a Tilt Angle or Height Thereof | 07-07-2016 |
