The invention discloses an integrated entertainment and exercise all-in-one machine for preventing senile dementia. The machine comprises a support, a base plate, a transmission mechanism, receiving mechanisms and plastic balls; the base plate is installed on the support, the transmission mechanisms are installed on the base plate, the receiving mechanisms are arranged on the outer sides of the transmission mechanisms, the plastic balls are arranged in the transmission mechanisms, circular holes are evenly formed in the base plate from left to right, and the positions of the circular holes arein one-to-one correspondence with the receiving mechanisms. Each receiving mechanism comprises a rotating frame, a fixed cylinder, a connecting plate, a driving branched-chain, a falling cylinder, asupport frame and a receiving frame, the transmission mechanism comprises a containing trough, a falling frame, a partition plate, a conveying frame, an auxiliary plate and a collecting basket, and each driving branched-chain comprises a worm wheel, a worm, a mounting rack and a collecting basket. Accordingly, the problems that at present, in daily life, old people do less exercise, potential safety hazards exist during exercise, brain training is insufficient, and the exercise process is tedious.
