At the same time, the gear of the cart is driven to travel on the rack by the servomotor, which is fixed at the center of the cart and is provided with double output axes and is provided with the axis of each side of a wheel and a gear is positioned at the middle part of the cart. The two driven wheels are arranged separately on each side of the trawl cart. The bracket is provided with two tracks on which the wheels are moved to carry out the position limiting of the chart. The utility model improves the working efficiency and the stepping precision. The stepping distance can be changed by the servomotor during the operation discretionarily, the serviceable range of the equipment is increased.
