“…Moreover, the picking machine executes the cutting mechanism on the fruit stalk to separate the fruit. The picked fruit is automatically transported to the fruit collection box under the guidance of the conveyor guide groove mechanism [30]. The semi-automatic screwing pineapple picking and collecting machine is manually moved to the upper end of the pineapple plant to determine the approximate position.…”

Pineapple harvesting is a key step in pineapple field production. At present, pineapple fruits are usually picked manually. With decreasing labor resources and increasing production costs, machines have been used instead of manual picking approaches in the modern pineapple industry. This paper briefly describes the basic situation of pineapple planting worldwide. Based on the degree of automation of mechanized pineapple harvesting equipment, the main structural forms, core technologies, and operation modes of semi-automatic, automatic, and intelligent pineapple harvesting equipment are summarized. The research status and existing problems of key pineapple fruit picking robots, such as fruit recognition, maturity classification, positioning, and separation of pineapple fruits, are analyzed. Considering the problems of pineapple harvesting equipment, such as difficulty entering the ground, low harvesting efficiency, low picking success rate, and fruit damage, innovative future research directions for mechanized pineapple harvesting technology are proposed, such as combining agricultural machinery and agronomical principles, integrating mechanized, automated, and intelligent technology, and developing modular designs and generalized approaches.

“…The picked fruit is transported to the compartment through the chain conveying mechanism. The tool lifting mechanism can be adjusted to cut pineapple fruits at different heights [32]. Because pineapple stalks are very brittle, the fruit can easily fall due to vibrations before the stalk is cut.…”

“…Xia et al [15] designed a pineapple harvesting manipulator which consists of a manipulator arm, an end-actuator, a positioning identification device, a travelling mechanism, a frame, a fruit box and a control system. Also, a semi-automatic pineapple picking machine, composed of a picking part, a lifting part, a pineapple conveying part, and a pineapple accumulate part was designed by Zhang et al [16]. Du et al [17]also developed an end effector based on physical characteristics of pineapple like mass, transverse diameter, vertical diameter, and stalk.…”

The pineapple (Ananas Comosus) is one of the most valuable commercial fruits in the world. Harvesting of pineapple is a major operation in pineapple cultivation and is laborious, and energy-intensive involving 306 man-hours per acre approximately. Manual harvesting by sickle is always injury-prone, which reduces the harvesting efficiency because the pineapple consists of long-pointed leaves usually needle-tipped and generally bearing sharp, up-curved spines on the margins. The maximum displacement of the outer skin of the pineapple due to compression force (70N) was observed at 10.63 mm on the Kew cultivar and 9.19 mm on Queen Cultivar. The maximum cutting energy and force of pineapple stalk were obtained as 1243.313 mJ and 168.15375 N respectively for the Queen cultivar and 2037.511 mJ and 190.91 N respectively for the Kew cultivar. A prototype of a semi-automatic pineapple harvester consisting of a grabbing unit with a linear actuator, cutting unit (cutting blade & DC motor), handle and the battery was designed and developed. The harvester was powered by a 12V 7Ah lead acid battery and had the capacity to harvest 200 fruits per hour. The harvesting time of the semi-automatic pineapple harvester is 30% higher than that of manual harvesting.

“…Desta forma Zhang et al (2018) relatam que a mecanização está entre as melhores opções a longo prazo para superar as restrições de produção no campo. O uso da mecanização na colheita de abacaxi não só libera bastante a força de trabalho, mas também é mais econômica e eficiente.…”
