A sweep auger system having a driveshaft with auger flighting and a backboard extending a length from an inward end to an outward end. An input of a gearbox is connected to an outward end of the drive shaft and a sweep wheel having a plurality of notches, arms and feet is connected to an output of the gearbox. A drive shield is placed around a rearward side of the sweep wheel that forms a channel that is configured to capture grain agitated by the sweep wheel. A guide plate is connected to the gearbox and covers a portion of the gearbox. The guide plate angles from an upper outward edge downward and forward to a lower inward edge that is configured to urge the grain captured within the channel of the drive shield to move in front of the sweep auger system reducing grain left in the grain bin.

A wall surface suction travel device includes a first travel unit, a second travel unit, a joint mechanism, and an elastic mechanism. The travel units are aligned along a travel direction and are each configured to travel on a wall surface while being suctioned on the wall surface. The joint mechanism couples the travel units together such that the travel units can pivot relative to each other on a pivot axis extending in a direction that is perpendicular to both a wall surface facing direction and the travel direction. The elastic mechanism includes a first end fixed to the first travel unit, a second end fixed to the second travel unit, and an elastic member configured to be elastically deformed when one of the travel units pivots relative to the other travel unit and a distance between the first end and the second end is shortened.

A traction enhancing device for a vehicle includes a plurality of spikes that is coupled to and extends from an outer face of a panel that is bendable and configured to conform to a circumference of a tire. A plurality of first straps and a plurality of second straps are coupled to a first edge and a second edge of the panel, respectively. Each second strap and an associated first strap are configured to loopedly position around the tire and a rim of a vehicle. Each of a plurality of first couplers and each of a plurality of second couplers are coupled to a respective first strap and a respective second strap, respectively, distal from the panel. Each second coupler is positioned to couple to an associated first coupler to couple the panel to the tire, positioning the spikes to insert into a substrate to increase traction of the tire.

A wheel apparatus for a self-propelled irrigation system has a center portion, a rim assembly, and a support structure disposed between the center portion and the rim assembly. The rim assembly has a plurality of rigid members spaced apart from each other with longitudinal axes that are parallel with each other and equidistant from the axis of rotation. The rigid members are cylindrical with unsupported ends, and a mounting portion between the ends is connected to an outer periphery of the support structure. The rigid members are held in a fixed position relative to the center portion by the support structure. The rigid members are arranged to contact the ground surface to support the irrigation system with spaces between the rigid members allowing mud and debris to pass freely between the rigid members during operation to enhance traction while minimizing mud from being forced out of a wheel track.

A kit for a wheel comprises a hub component in the form of an annular body defining a central opening for receiving a shaft on which the wheel is to be mounted, at least one outer rim component adapted to form a substantially circular periphery of the wheel and a plurality of spoke components adapted to interconnect the at least one outer rim component and the hub component with each of the spoke components being arranged at a respective angular position about the hub component. Each outer rim component is formable from a blank comprises a main body which defines an outer ground engaging surface of the wheel, a pair of strips consecutively attached to one end of the main body in a manner such that each strip is movable relative to the adjacent element about a transverse folding axis, so that the strips can be folded to define a peak projecting outwardly to form a wheel rim with fins.

A wall surface suction-type travel device includes a first travel unit, a second travel unit, a joint mechanism, and an elastic mechanism. The first and second travel units are aligned along a travel direction and are each configured to travel on a wall surface while being suctioned on the wall surface. The joint mechanism couples the first and second travel units together such that the travel units can pivot relative to each other on a pivot axis extending in a direction that is perpendicular both to a wall surface facing direction and the travel direction. The elastic mechanism includes a first end fixed to the first travel unit, a second end fixed to the second travel unit, and an elastic member configured to be elastically deformed when one of the first and second travel units pivots relative to the other travel unit and a distance between the first end and the second end is shortened.

A traction enhancement device and system for the rear wheel(s) of a wheelchair is provided. The traction enhancement system generally includes a tooth bar assembly that includes a plurality of spikes/teeth and an actuation assembly that includes a lever and swashplate. In use the lever can be moved into ground engaging position and the swashplate will contact and provide a force the tooth bar assembly causing the spikes to extend beyond the diameter of the wheelchair wheel and into engagement with the surface on which the chair is riding. The lever can be pulled out of ground engaging position and the swashplate will not cause the spikes to push outwardly beyond the diameter of the wheel.

A transformable wheel includes a wheel frame including a plurality of contact portions and a plurality of recessed portions. A plurality of transforming members is provided wherein one side of each transforming member is rotatably coupled to a corresponding one of the recessed portions and an outer surface of each transforming member forming a portion of the wheel frame. A rotating member is provided at one side surface of the wheel frame, and includes a plurality of transformation locking members arranged radially from the central axis of the wheel frame to correspond to the plurality of transforming members, respectively. A driving member is configured to rotate the rotating members by a preset angle about the central axis of the wheel frame.
