The roller pulley and the lower roller shaft are connected by key, and there is a roller bearing between the roller pulley on the upper roller shaft and the upper roller shaft, and the roller pulley on the upper roller shaft on the same side and the roller pulley on the lower roller shaft The roller belt is connected to form a belt transmission; the lower roller and the upper roller are connected by a ball picking belt to form a belt transmission; the lower end of the bottom panel of the ball picking rack is fixed and connected to an elastic pressure plate by 5 pressure plate screws, and the elastic pressure plate is elastic. The lower end of the ball belt forms the tennis entrance; the cavity between the bottom panel of the ball picking rack and the ball picking belt forms a tennis channel, and a veneer is pasted on the bottom panel of the ball picking rack in the tennis channel, and the veneer is elastic; There is an opening at the top, which is set as a tennis outlet, and the height of the lowest point of the ball picking belt from the ground is slightly smaller than the diameter of the tennis ball; in the remote control power mechanism: an electric control box is provided in the car box, and the electric control box includes a power supply. , remote control signal receiving device, and motor circuit control device, which function as the power source of the motor, can receive and process remote control signals and send motor working signals, and control the work of the motor; two motors are symmetrically arranged in the electric control box, and the motors are fixed on the carriage On the inner side of the side panel of the body, the motor shaft extends out of the car body, and the motor pulley is installed on the motor shaft. The motor pulley is fixed on the motor shaft by the motor shaft pin. The belt is connected to form a belt drive; the input pulley is installed on the one-way bearing of the motor, the one-way bearing of the motor is installed on the toothed wheel, the toothed wheel is installed on the inner front wheel bearing of the front wheel shaft, and the front wheel bearing is installed on the front On the wheel shaft; the one-way bearing of the motor only allows the input pulley to rotate clockwise around the pair of teeth, that is, the counterclockwise rotation of the input pulley drives the rotation of the pair of teeth counterclockwise, and the counterclockwise rotation of the pair of teeth cannot drive the rotation of the input pulley There are gear teeth on the pair of convex teeth, and tooth grooves are arranged on the inner end surface of the front wheel, and the teeth on the pair of convex teeth are inserted into the tooth grooves of the front wheel to realize the connection between the input pulley and the front wheel; the front wheel is installed On a pair of front wheel one-way bearings, the front wheel one-way bearings are installed on spacers, the spacers are installed on a pair of front wheel bearings, and the front wheel bearings are installed on the front wheel axles, and the front wheel one-way bearings only allow the front wheels to Rotate clockwise around the spacer, that is, the counterclockwise rotation of the front wheel drives the counterclockwise rotation of the spacer, and the counterclockwise rotation of the spacer cannot drive the front wheel; a large pulley is installed on the outermost front wheel bearing on the front wheel shaft, and the large pulley is connected with the The spacer is fixedly connected by the connecting pin of the large pulley, and the large pulley and the small pulley on the lower roller shaft are connected by a power belt to form a belt rotation; in the folding mechanism: there are rings fixedly connected to the front of the two side panels of the car body. The club seat; one end of the ring club seat is provided with a vertical light hole, and each of the two ends of the ring club is provided with a vertical threaded hole, and the locking screw is screwed into the ring club through the light hole of the ring club seat. The threaded hole realizes locking the position of the ring club seat and the ring club; similarly, one end of the extension rod is provided with a vertical light hole, and another locking screw is screwed into the ring ball through the light hole of the extension rod. The threaded hole of the rod realizes the position of the locked ring club and the extension rod; when the locking screw is not tightened, the ring club and the extension rod can rotate around the locking screw; Rods, extension rods and locking screws are connected to form a fan-shaped circle area with a large outside and a small inside; at the rear of the panels on both sides of the car body, there are support rods hinged by the locking screws of the support arms, and the support rods and the support arms are formed by The other arm is hinged by locking screws, and the upper ends of the left and right support arms are fixedly connected with hand push rods. There is a card slot in the middle of the support arm, and the front end of the support arm is hinged on the upper roller shaft; The arm and the support rod constitute a four-bar mechanism. After the locking screw of the support arm is tightened, the positions of the ball pick-up frame, the support arm and the support rod are fixed relative to the box body. A flexible gauze is installed on the rod, and the gauze has flexibility and elasticity and can be folded.
