His astonishing outburst came in his second round tie against 76th-ranked qualifier Ruud who had won the first set 6-3.
Kyrgios won the second set 7-6 (7/5) to level, but was furious after sending a forehand wide to hand a break back to Ruud early in the third set.
The 24-year-old turned and berated the crowd for walking during the point before slamming his racquet to the floor amid a string of swear words.
Kyrgios told a spectator: "You're not supposed to walk across the court as I'm serving, do you understand that?"
Kyrgios then received a code violation for unsportsmanlike conduct and a game penalty, with the umpire calling the tournament referee courtside.
"I'm giving 100 percent. I don't want to play when this shit is going on," Kyrgios was heard saying.
His then kicked a water bottle, before throwing a chair across court, packing his bag, shouting "I am fucking done".
The Australian later posted "" along with crying with laughter emojis alongside a clip of Ruud celebrating going through 6-3, 6-7 (5/7), 2-1 to the third round.
Kyrgios had earlier whipped up a storm over comments made about Djokovic and Nadal in an interview with .
"I just feel like he's got a sick obsession with wanting to be liked," he said of world No 1 Djokovic.
"He just wants to be (Roger) Federer. I feel he wants to be liked so much that I just can't stand him. This celebration thing is so cringeworthy.
"He's unbelievable, a champion of the sport, one of the greatest we will ever see. I think he will get the Grand Slam count and overtake Federer.
"No matter how many Grand Slams he wins, he will never be the greatest to me. I've played him twice and I'm sorry but if you cannot beat me, you cannot be the greatest of all time.
"For me, Federer will always be the greatest of all time. What Rafa has done has been pretty scary too. But Novak just riles me the wrong way. He always says what he thinks he needs to say rather than his actual opinion."
He also said Nadal, who had lambasted the Australian as "disrespectful" after losing to him in Mexico earlier this year, was a bad loser.
"He's just my polar opposite, like literally my polar opposite. And he's super salty," said Kyrgios.
"When he wins, it's fine. He won't say anything bad, he'll credit the opponent - 'he competed well today, he's a great player,' but then as soon as I beat him, it's just like 'he has no respect for me, my fans and no respect for the game' - and I'm just like 'what are you talking about?'"
Kyrgios has a long and chequered history when it comes to discipline.
In 2015, in one of his more notorious outbursts, he was fined for making a sexually disparaging remark in Canada about the girlfriend of three-time major winner Stan Wawrinka.
