摘要:
A harvester incorporating at least one force balanced shaker vibratory brush as the harvesting apparatus uses a sensing system connected to spring feelers to generate a signal responsive to the location, shape and position of a tree.

An array of foliage contacting rods having a certain stiffness and trunk contacting rods having a greater stiffness is assembled in combination for mounting on an oscillatory shaker head configured to be carried over row cultivated crops by a mobile harvester to effect crop harvesting by both foliage shaking and trunk shaking using a single shaker head. Moreover, the number of rods of each type may be varied to suit harvesting conditions while the oscillatory shaker head remains in place in the mobile harvester and the stiffness of each rod is adjustable within limits to further conform to harvesting conditions. The rod array in one embodiment provides simultaneous harvesting of multiple rows of a crop cultivated in parallel row configuration.

A net rotation speed control system for an oscillatory shaker head assembly driven by a force-balance drive carried on a crop harvester has a harvester forward velocity signal input. Also provided is an operator input for selecting appropriate speed relationship between the harvester velocity and the net shaker head rotation velocity. The system is useful as an open loop system, but is improved to correct for otherwise uncontrolled operating conditions by incorporating a speed sensor for net shaker head rotation velocity and closing the loop by connecting an output from the net rotation speed sensor to the control system.
摘要:
A over-the-row single sided harvester harvests a row crop from a first side of a row while simultaneously collecting crop from the “off side” side of the same row.
摘要:
An improved gondola assembly for receiving harvested crops in the field from a crop harvester has a lightweight molded drop in tank held in place by a tank framework on the gondola assembly. The drop in tank lowers the gondola center of gravity as it replaces stainless steel or painted mild steel tanks and requires no periodic maintenance. A built in scale for continuous in the field monitoring of the weight of received harvested crop is constructed to be viewable by a tow tractor operator whether towed from one end of the gondola or the other. The towable gondola obtains power for operation of a pair of tank framework lift cylinders from the tow tractor so that the tank is movable between an elevated dump position and a lowered crop collection position. The gondola has a reversible towing tongue for towing in either direction so it may be configured to be towed on either side of a crop harvester.
摘要:
A harvester for tree borne fruit is disclosed wherein a power driven vehicle is provided for following a course adjacent and parallel to a row of fruit trees. The vehicle carries a vibratory brush having tines for engaging and shaking the tree's fruit bearing branches. The brush is yieldably held in engagement with the fruit bearing branches and is adjustable in three aspects, elevation, tilt angle and lateral position, to assume an optimum position relative to the row of trees. A brake is provided to control a net rotation speed of the vibratory brush within the branches. A resilient screen deflects randomly projected harvested fruit toward a harvested fruit catch apparatus. The tines are covered with an optimally designed resilient cover for reducing cullage in the harvested fruit.
