The invention discloses a funnel vehicle, a bottom door opening/closing mechanism of the funnel vehicle and a control method of the bottom door opening/closing mechanism. The mechanism comprises a transmission shaft (1), a connecting rod mechanism and a rotating arm, wherein one end of the rotating arm is fixedly connected with the transmission shaft (1). The bottom door opening/closing mechanism is characterized in that the connecting rod mechanism comprises a fixed connecting rod and a connecting rod; one end part of the fixed connecting rod is fixedly connected with the transmission shaft (1); the two end parts of the connecting rod are hinged to the other end part of the fixed connecting rod and a bottom door (4) respectively; the bottom door opening/closing mechanism further comprises a detection device and a controller; the detection device is used for detecting a signal for indicating the distance between a connecting line of hinge points on the two end parts of the connecting rod and a transmission center of the connecting rod; the controller is used for judging whether or not the distance between the connecting line of the hinge points at the two ends of the connecting rod and the transmission center of the connecting rod is within the safety closing numerical value range of the bottom door. By adopting the bottom door opening/closing mechanism, the phenomenon of driving under the situation that the bottom door is not closed in place can be overcome, and the driving safety is enhanced; moreover, through the way of judging whether or not the bottom door is closed in place, the structure is relatively simple and feasible.
