Smashing trolley for Bingbing court

Technical field

The invention belongs to the technical field of sports equipment auxiliary facilities, and in particular relates to a spiking trolley used on a military field.

Background technique

Table tennis is becoming more and more popular as a national fitness sport. Due to the small size and flexibility of table tennis balls, picking up the balls has become a burdensome task. Manual ball picking is time-consuming and laborious, and has basically been abandoned; tool ball picking is currently mainly divided into two forms, one is a simple homemade ball picking machine, and the other is an intelligent mechanical ball picking machine suitable for large table tennis courts. The simple homemade ball picker is simple to make, but it still requires manual operation of the ball storage facility to continuously smash the ball into the ball storage facility. Once a large number of table tennis balls appear on the field, picking up the balls is still a very time-consuming and laborious task; large-scale Although the intelligent mechanical ball picking machine in table tennis courts overcomes the shortcomings of simple homemade ball picking machines, it is expensive and not suitable for use in small and medium-sized courts.

Detailed ways

The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

As shown in Figures 1-4, the spiking trolley of the present invention for use in military courts is characterized in that it includes a trolley frame 1, and a shaft sleeve 13 is arranged on the trolley frame 1, and is arranged on the shaft. The dual output shaft motor 16 in the sleeve 13 is respectively provided with two couplings 15 on both sides of the dual output shaft motor 16 and connected to the two output ends of the dual output shaft motor 16, respectively. The two main shafts 12 connected by the two couplings 15, the spiking driving devices respectively provided on the two main shafts 12, and the ball collecting devices connected to each spiking driving device are connected to each other through bearings II 18 respectively. The two wheels 2 are rotatably connected at the ends of the two main shafts 12,

The two main shafts 12 are rotatably connected to the shaft sleeve 13 through bearings I14, respectively.

Each spiking drive device includes an oblique support rod 10 fixedly connected to the trolley frame body 1, a driven gear 4 rotatably connected to the upper end of the oblique support rod 10, and a driven gear 4 meshing with the driven gear 4. Driving gear 3, a hinge point 5 provided on the circumferential edge of the driven gear 4, a hinge rod 6 with its A end hinged to this hinge point 5, and a hinge rod 6 with its B end hinged to the ball collecting device. , the upper ends of the inclined struts 10 of the two spiking driving devices are connected through the connecting shaft 7, and the lower ends of the inclined struts 10 of the two spiking driving devices are in contact with the ground,

The driving gear 3 of each spiking drive device is connected to the corresponding main shaft 12 through a key 17 .

The ball collecting device includes a ball collecting box 8 which is composed of a front smashing chamber and a rear storage chamber. A drooping curtain is arranged between the ball smashing chamber and the storage chamber and is hingedly connected to the ball collecting box 8. 9. A set of elastic ropes 20 arranged in parallel at the bottom of the spiking chamber, and two connecting rods 11 arranged at the rear of the storage chamber. These two connecting rods 11 are respectively connected with the two spiking balls. The lower end of the inclined support rod 10 of the driving device is hinged, and the front part of the ball-spinning chamber is hinged with the B end of the hinge rod 6.

In the set of elastic cords 20 arranged in parallel, the distance between every two elastic cords 20 is 4cm-5cm.

There is an absorbent cloth 19 at the bottom of the storage cavity.

The invention is mainly used in table tennis activity venues or training venues. The venue staff pushed the smash car to look for table tennis balls. When a table tennis ball is found, the dual output shaft motor 16 is started, and the spiking mechanism starts to work. The ball collection box 8 and each spiking drive device form a crank rocker mechanism. According to the working principle of the crank rocker, the dual output shaft motor 16 The two driving gears 3 and the two driven gears 4 are driven to rotate. The B end of the hinge rod 6 is hinged with the ball box 8. The A end of the hinge rod 6 is hinged with the hinge point 5 on the peripheral edge of the driven gear 4. The crank rocker movement is realized, and the hinge rod 6 drives the ball collection box 8 to realize the functions of dropping and lifting the ball, picking up the ball, and storing the ball. The ball collecting box 8 is divided into two parts. The front end is a spiking cavity, and the back is a storage cavity, which is divided by a drooping curtain 9 in the middle. When the ball box 8 is lifted, the drooping curtain 9 hinged with the ball box 8 always maintains a 90-degree vertical relationship with the ground, so that the spiking chamber and the storage chamber form an opening, and the table tennis balls enter the storage chamber by gravity.

On both sides of the ball-collecting box 8 spiking cavity, smooth elastic ropes 20 with elasticity are arranged every 4cm-5cm. The distance between elastic ropes 20 cannot be larger than the diameter of a table tennis ball. When the ball collecting box 20 is buckled downward to the ground, the table tennis balls enter the spiking cavity through the elastic elastic rope 20 with a smooth belt to realize spiking and picking up the ball. The drooping curtain 9 droops to block the table tennis balls in the storage cavity to realize a spiking and picking up the ball. and storage ball loops.

Players' sweat often drips on the table tennis court. During the process of smashing and picking up the ball, the absorbent cloth 19 bonded at the bottom of the ball collection box 8 can absorb the moisture in the court.

The invention has a simple structure and is easy and quick to operate. The crank rocker mechanism is used to operate the spiking mechanism, so that the bottom surface of the spiking mechanism is aligned with the table tennis ball and is gently pressed into the ball collecting box 8. The elastic rope at the bottom of the spiking mechanism is 20 is smooth and spaced, and the table tennis balls can easily enter the ball collecting box 8, thereby improving the ball picking efficiency.
