The invention discloses an intelligent gate groove of a screw starting and stopping machine. The intelligent gate groove comprises a gate, a first gate groove body, a second gate groove body and steelwire ropes, and the gate and the first gate groove body are correspondingly installed. The intelligent gate groove is characterized in that the steel wire ropes are arranged at the four feet of the top of the gate, the second gate groove body is arranged at the bottom of the gate, the four corners on the second gate groove body are connected through the steel wire ropes extending at the four corners of the top of the gate, a hook is fixed to each steel wire rope, four fixing handles are arranged at the upper and lower positions of the front and back sides of the gate, the second gate groove body is arranged at the upper portion of the first gate groove body, and the first gate groove body and the second gate groove body are installed together in a matched manner. The intelligent gate groove has the beneficial effects that when the second gate groove body needs to be cleaned, the four steel wire ropes are hung on the fixing handles through the hooks, the gate and the second gate groovebody are lifted up together, hard objects in the second gate groove body are cleaned, and then the second gate groove body is placed on the underwater first gate groove body. The first gate groove body does not need to be cleaned, only the second gate groove body needs to be cleaned, stone or hard objects can be prevented from falling into the first gate groove body, and a starting and stopping machine screw is jacked to be bent or pulled to be broken.
