Track belt and a track assembly
10894560 · 2021-01-19 · ·

A track belt comprises a bearing element having an inner surface, an outer surface and a width. On the inner surface, a guide element extends in the longitudinal direction of the track belt, comprising a first edge protrusion and a second edge protrusion. The width of the guide element is substantially smaller than the width of the bearing element. The track belt comprises a first guide groove having a first flank surface formed by the first edge protrusion, and a second guide groove having a first flank surface formed by the second edge protrusion. The first flank surfaces of the edge protrusions are uniform and continuous substantially over the entire length of the guide element. Preferably, the guide element comprises a traction surface parallel to the inner surface of the bearing element, having engaging members for receiving the engaging parts of the drive wheel.

Crayfish/crawfish harvesting method and apparatus
10759505 · 2020-09-01 ·

A crayfish or crawfish harvesting apparatus employs an improved drive that uses hydraulic wheels (e.g., rubber tired wheels) encircled by one or more endless belts. One or more hydraulic motor drives can be used to drive the wheels. Lugs or guide lugs are placed on opposing sides of each wheel and are preferably connected to the belt. Fasteners (e.g., bolts or rivets) attach cleats (e.g., steel u-shaped channel cleats) to the belts and lugs.

Crawler

A crawler includes a crawler main body (a rubber crawler main body (12)), a tensile body (70), guide protrusions (16), and flat surfaces (40). The tensile body (70) is provided with a flat portion (72) that is arranged along a width direction of the crawler main body and a slanting portion (74) that is slanted and arranged at a width direction outer side of the crawler main body relative to the flat portion (72). The guide protrusions (16) are formed at an inner peripheral face of the crawler main body at a width direction middle portion of the crawler main body. The flat surfaces (40) are formed at the width direction outer sides of the crawler main body relative to the guide protrusions (16). Turning wheels (a driving wheel (100), an idling wheel (102) and rolling wheels (104)) provided at a vehicle roll on the flat surfaces (40). In a linear region of the crawler main body as seen in a side view of the crawler main body, if a thickness from an imaginary plane projected from the flat portion (72) in the width direction of the crawler main body to an end edge at a crawler main body width direction outer side of the slanting portion (74) is represented by L, then a result of subtracting a turning direction length of the crawler main body at the flat portion (72) from a turning direction length of the crawler main body at the slanting portion (74) is less than 2L.
