Irrigation pipe laying and pick up vehicle
First Claim
1. A vehicle for picking up and laying irrigation pipe of the type consisting of a plurality of rigid sections and couplings between the sections forming a line of pipe, said vehicle comprising:
- a vehicular frame having a raised platform,inclined guide means mounted on said frame at a first end of said vehicle for guiding the end of a section of irrigation pipe being picked up from the ground level to above the level of said platform as said vehicle is operated toward said line of pipe and for guiding the pipe section down said guide means as said vehicle is operated away from said line of pipe,rack means adjacent said platform for supporting a plurality of said sections of irrigation pipe in stacked relationship,uncoupling means for uncoupling a section of said pipe being picked up from the subsequent pipe section,said uncoupling means comprising angulation guide means for guiding the free end of the leading pipe section and elevating said end relative to the longitudinal axis of the adjacent section.

Abstract
A self-propelled vehicle having a centrally mounted inclined guide trough for guiding pipe sections as the vehicle is driven along a row of attached pipe sections. The sections are guided upwardly to the level of a working platform. An angulation trough contacts the end of a pipe section and angulate a first pipe section relative to the next section so that the first section can be disconnected. Disconnected sections are placed in racks on either side of the platform. The two ends of the guide trough have different inclinations to aid in the assembly of the pipe sections when laying pipe.

17. A vehicle for picking up and laying irrigation pipe of the type consisting of a plurality of rigid sections and couplings between the section forming a line of pipe, said vehicle comprising:
-
a vehicular frame having a raised platform, inclined guide means mounted on said frame at a first end of said vehicle for guiding the end of a section of irrigation pipe being picked up from the ground level to above the level of said platform as said vehicle is operated toward said line of pipe and for guiding the pipe section down said guide means as said vehicle is operated away from said line of pipe, rack means adjacent said platform for supporting a plurality of said sections of irrigation pipe in stacked relationship, uncoupling means for uncoupling a section of said pipe being picked up from the subsequent pipe section, said inclined guide means is centrally located on said vehicle, two racks are mounted on said vehicle, each being adjacent to, but on opposite sides of, the centrally mounted inclined guide means, said racks are mounted for movement between a first position closely adjacent said inclined guide means and a second horizontally and outwardly displaced position, said racks comprising a plurality of horizontal support members carried on said vehicle by a parallel bar linkage, actuator means for powering said racks from said first to said second positions, said second positions being horizontally, outwardly displaced from said vehicle and being lower than said first position, a plurality of uprights on said horizontal support members, said uprights being selectively movable between a first upright position and a second position whereby said pipe may be withdrawn horizontally from said rack.
