Abstract:

A portable pipe irrigation system that is used primarily for temporary drip and sprinkler installations includes a unique trailer that comprises a platform which simplifies installation and removal of the irrigation system. The trailer is either self propelled or pulled by a tractor. A magazine in the central portion of the trailer is of a sufficient length to accommodate pipe of various lengths and cross sections. A work platform is located at either end of the magazine, allowing workers to manipulate the pipe in the magazine and load the pipe into one of two installation chutes. Catwalks are located on one or both sides of the magazine. Two chutes or channels are located on the platform at a comfortable work level. A primary chute is located closest to the magazine and is fitted with a fixed stop on the front end and a pushing lever on the rear end. A secondary chute is provided for final assembly of the pipe sections.

Abstract:

A portable pipe irrigation system that is used primarily for temporary drip and sprinkler installations includes a unique trailer that comprises a platform which simplifies installation and removal of the irrigation system. The trailer is either self propelled or pulled by a tractor. A magazine in the central portion of the trailer is of a sufficient length to accommodate pipe of various lengths and cross sections. A work platform is located at either end of the magazine, allowing workers to manipulate the pipe in the magazine and load the pipe into one of two installation chutes. Catwalks are located on one or both sides of the magazine. Two chutes or channels are located on the platform at a comfortable work level. A primary chute is located closest to the magazine and is fitted with a fixed stop on the front end and a pushing lever on the rear end. A secondary chute is provided for final assembly of the pipe sections. The secondary chute has a lever of a much longer radius that travels along the length of the chute. The two chutes define work areas where the pipe sections are assembled or disassembled. At the rear of the trailer/platform are outriggers that assist in the accurate placement of pipe in the field.
