The lower side of the mounting base 2 is connected to three equidistantly distributed lower hoppers 4. The front and rear sides of the middle part of the base 1 are fixedly connected to the first motor 5, and the output shaft of the first motor 5 is fixedly connected to the first cam 6. The front and rear sides of the middle part of the mounting base 2 are fixedly connected to the cross bar, and the first cam 6 rotates to be squeezed into cooperation with the cross bar.
