Detailed Description

The following further describes the embodiments of the present invention with reference to the drawings.

As shown in fig. 1-4, the utility model discloses a smash dolly for soldier ball field, which is characterized in that it comprises a dolly frame body 1, an axle sleeve 13 arranged on this dolly frame body 1, a dual output shaft motor 16 arranged in this axle sleeve 13, two couplings 15 respectively arranged on both sides of this dual output shaft motor 16 and respectively connected with two output ends of the dual output shaft motor 16, two main shafts 12 respectively connected with the two couplings 15, smash driving devices respectively arranged on the two main shafts 12, a ball collecting device connected with each smash driving device, two wheels 2 respectively connected with the ends of the two main shafts 12 through bearings ii 18 in a rotating way,

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 engaged with the driven gear 4, a hinge point 5 arranged on the circumferential edge of the driven gear 4, a hinge rod 6 with an A end hinged with the hinge point 5, a B end of the hinge rod 6 is hinged with the ball-collecting 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 driving gear 3 of each ball-catching driving device is connected with the corresponding main shaft 12 through a key 17.

Ball collecting device include by the anterior ball collecting box 8 of detaining ball chamber and rear portion storage chamber and constituteing, set up detain between ball chamber and the storage chamber and with ball collecting box 8 looks articulated flagging curtain 9 sets up detain a set of parallel arrangement's of ball chamber bottom bungee 20, set up and be in two connecting rods 11 at storage chamber rear portion, these two connecting rods 11 respectively with two detain ball drive arrangement's the lower part end of down-tube pole 10 articulated mutually, detain ball chamber anterior with articulated rod 6's B looks articulated mutually.
