Detailed Description
Specific embodiments of the present invention are further described below with reference to the accompanying drawings.
As shown in fig. 1 to 4, the ball-catching trolley for a court of Yu Bing of the present invention is characterized by comprising a trolley frame body 1, a shaft sleeve 13 arranged on the trolley frame body 1, a double output shaft motor 16 arranged in the shaft sleeve 13, two couplings 15 respectively arranged at both sides of the double output shaft motor 16 and respectively connected with two output ends of the double output shaft motor 16, two main shafts 12 respectively connected with the two couplings 15, ball-catching driving devices respectively arranged on the two main shafts 12, a ball-collecting device respectively connected with each ball-catching driving device, two wheels 2 respectively connected with the ends of the two main shafts 12 in a rotating way through bearings ii 18,
the two main shafts 12 are respectively connected with the shaft sleeve 13 in a rotating way through bearings I14,
each ball-catching driving device comprises an inclined strut 10 fixedly connected with the trolley frame body 1, a driven gear 4 rotationally connected with the upper end of the inclined strut 10, a driving gear 3 meshed with the driven gear 4, a hinging rod 6 with an end A hinged with the hinging point 5 and a hinging point 5 arranged on the circumferential edge of the driven gear 4, a B end of the hinging rod 6 hinged with the ball-catching device, the upper ends of the inclined struts 10 of the two ball-catching driving devices are connected through a connecting shaft 7, the lower ends of the inclined struts 10 of the two ball-catching driving devices are abutted against the ground,
the drive gear 3 of each ball drive is connected to the corresponding spindle 12 by means of a key 17.
The ball collecting device comprises a ball collecting box 8 consisting of a front ball catching cavity and a rear storage cavity, a drop curtain 9 which is arranged between the ball catching cavity and the storage cavity and is hinged with the ball collecting box 8, a group of elastic ropes 20 which are arranged in parallel at the bottom of the ball catching cavity, two connecting rods 11 which are arranged at the rear of the storage cavity, the two connecting rods 11 are respectively hinged with the lower ends of inclined struts 10 of the two ball catching driving devices, and the front part of the ball catching cavity is hinged with the end B of the hinging rod 6.
The interval between every two elastic ropes 20 is 4cm-5cm.
The bottom of the storage cavity is provided with a water absorption cloth 19.
The invention is mainly applied to table tennis playgrounds or training grounds. Stadium staff pushes the smalls for playing the table tennis. When the table tennis is found, the double-output-shaft motor 16 is started, the ball catching mechanism starts to work, the ball collecting box 8 and each ball catching driving device form a crank rocker mechanism, according to the working principle of the crank rockers, the double-output-shaft motor 16 drives the two driving gears 3 and the two driven gears 4 to rotate, the end B of the hinge rod 6 is hinged with the ball collecting box 8, the end A of the hinge rod 6 is hinged with the hinge point 5 on the circumferential edge of the driven gears 4, the movement of the crank rockers is achieved, and the hinge rod 6 drives the ball collecting box 8 to achieve falling and lifting ball catching and storage functions. The ball collecting box 8 is divided into two parts, the front end is a ball catching cavity, the rear end is a storage cavity, and the middle is divided by a drooping curtain 9. When the ball collecting box 8 is lifted, the drooping curtain 9 hinged with the ball collecting box 8 always keeps a vertical relation of 90 degrees with the ground, so that an opening is formed between the ball catching cavity and the storage cavity, and the table tennis enters the storage cavity under the action of gravity.
Smooth elastic ropes 20 with tightness are arranged at intervals of 4cm-5cm at two sides of the ball catching cavity of the ball collecting box 8. The spacing between bungee cords 20 cannot be greater than the diameter of a table tennis ball.
