A certain construction site uses several large and small trucks to transport 580 tons of soil. It is known that the weight of the large truck is 10 tons, and the weight of the small truck is 6 tons. There are 2 more large trucks than small trucks, and each vehicle transports 5 tons. The soil was transported the next time. How many trucks are there?
某建筑工地用大小卡车若干辆将580吨土运走，已知大卡车载重量是10吨，小卡车载重量是6吨，大卡车比小卡车多2辆，且每辆车都运了5次才将土运完，问有几辆打卡车？
