Design of an Automatic Multi-adjustment Device for Throwing Embroidered Ball in Traditional Ethnic Sports
Throwing embroidered ball has a long history in the traditional sports of ethnic minorities in Guangxi.However,the existing equipment specifications for throwing embroidered ball are mainly applicable to junior high school students and adult participants.Therefore,the participation of children and the elderly is greatly reduced,and the promotion of throwing embroidered ball is limited.An automatic multi-adjustment device for throwing embroidered ball in traditional ethnic sports is designed.The device is composed of adjustable ring,support rod,positioning plate,motor,chain,sprocket and wheel frame.The designed embroidered ball throwing device solves the problem that the existing device cannot automatically adjust the height of the high pole and the size of the pitching circle.By increasing the lifting of the wheel frame and the support rod,it improves the efficiency of the device's moving and handling and the problem of the device's occupation.It has great practicability and market promotion and application value,and can also provide guarantee for the traditional ethnic sports teaching and exercise equipment in minority areas and promote the development of the embroidered ball throwing sport.
