A tractor, including a frame, a power wheel and a connecting assembly. The power wheel is rotatably arranged on a bottom of the frame. The connecting assembly is arranged on the frame and is configured to be attached to a goods carrier. The power wheel is rotatable relative to the frame to drive the frame to move, so as to drive the goods carrier to move synchronously through the connecting assembly. The connecting assembly is configured to move back and forth along a first direction relative to the frame to render a relative position between the goods carrier and the frame adjustable along the first direction. The first direction is a travelling direction of the tractor.

A method for constructing an efficient product surface defect detection model based on network collaborative pruning is provided. According to an initial product surface defect detection model, the method provides a network-based collaborative pruning method and constructs the efficient product surface defect detection model. On a premise of ensuring an accuracy of a product defect detection method, a product surface defect detection time is reduced to satisfy manufacturer's requirements on the product surface defect detection time and accuracy of product surface defects.

Electric sausage filler

Disclosed is a lightweight electric earth drill including a mounting plate, a drill stem and an outer shell, a motor installed on the mounting plate and configured to drive the drill stem to rotate, a rechargeable battery configured to power the motor, and a controller configured to control the motor and electrically connected to the motor and the rechargeable battery. The lightweight electric earth drill is driven by the motor and has low noise, which causes less damage to health of the workers and does not disturb the residents around the construction site. The lightweight electric earth drill is powered by rechargeable battery or mains electricity without exhaust emission. The motor is controlled by the controller and rotates forwardly and reversely, enabling the drill bit to be pulled out after drilling the earth.

The invention relates to an automatically-limiting electric sausage filler and control methods thereof. A piston is positioned at the tail end of a toothed piston rod and integrated as a whole; a DC motor drives an automatic shaft, the automatic shaft is meshed with the toothed piston rod through a gear train to drive the toothed piston rod to move up and down in a material cylinder, a meat outlet is formed at the bottom of the material cylinder, when the piston is arranged at the bottom of the material cylinder, the electric sausage filler has a lower limit; when the piston is arranged at the top of the material cylinder, the electric sausage filler has an upper limit; a lower limit signal detection element and an upper limit signal detection element are arranged on two sides of the toothed piston rod and correspond to an upper limit magnet strip and a lower limit magnet strip embedded on the toothed piston rod in an induction manner, and induction signals of the lower limit signal detection element and the upper limit signal detection element are sent to a control circuit which outputs a control signal to drive the DC motor to work. By virtue of the upper limit and the lower limit, the electric sausage filler is controlled to automatically fill sausages, overcurrent protection function is added in the control circuit for protecting the motor from stalling, so that a motor stalling protection device is omitted, and the cost is reduced; the sausage filling operation is simplified by virtue of the upper limit and the lower limit; and by virtue of the movement of the piston, the sausage filling process is fully automatic.
