The tennis balls on the left side can be collected by synchronously driving the swinging of the pair of swing arms through arranging the pair of swing arms on the two sides of the left end of the collecting groove body and driving the swing arms to swing by the driving motor A, and the tennis balls entering the inner sides of the pair of swing arms can be collected into the collecting groove body through the guide inclined plates in the swinging process that the outer ends of the pair of swing arms are close to the guide inclined plates; tennis balls can enter the collecting groove body after passing through the highest point of the guide inclined plate; the left half part of a first collecting cylinder in a first rotating distribution mechanism is of an open structure, and the lower part of the first collecting cylinder is communicated with the right end of a collecting groove body through a first transition plate, so that tennis balls can smoothly enter the lower part of the first collecting cylinder; the second shifting plates fixedly connected with the right end of the bottom plate B can receive tennis balls shifted by the first rotary distribution mechanism and transfer the tennis balls into the lower accommodating chamber, and the subsequently shifted tennis balls can continuously enter the second shifting plates and enter the lower accommodating chamber along with the continuous rotation of the first rotary shaft; due to the arrangement that the bottom plate B is low at the left and high at the right, tennis balls can smoothly reach the left end of the lower containing chamber; the right half part of a second collecting cylinder in the second rotary distribution mechanism is of an open structure, and the lower part of the second collecting cylinder is communicated with the left end of the lower containing chamber through a second transition plate, so that tennis balls entering the left end of the lower containing chamber can smoothly enter the lower part of the second collecting cylinder, and meanwhile, in the process that a second rotating shaft drives a plurality of second shifting mechanisms on the second rotating shaft to synchronously rotate clockwise, tennis balls entering the second collecting cylinder can be shifted up and do movement around the direction of the second rotating shaft under the shifting action of a third shifting plate, and therefore tennis balls can reach the middle containing chamber; a plurality of fourth shifting plates fixedly connected with the left ends of the second transverse partition plates can receive tennis balls shifted by the second rotary distribution mechanism and transit the tennis balls into the middle containing chamber, and along with the continuous rotation of the second rotary shaft, subsequently shifted tennis balls can continuously enter the third shifting plates and enter the middle containing chamber; the tennis ball can smoothly reach the right end of the middle containing chamber due to the arrangement that the second partition plate is inclined in a manner of being higher at the left and lower at the right; the left half part of a third collecting cylinder in the third rotary distribution mechanism is of an open structure, and the lower part of the third collecting cylinder is communicated with the right end of the middle containing chamber through a third transition plate, so that tennis balls entering the right end of the middle containing chamber can smoothly enter the lower part of the third collecting cylinder, and meanwhile, in the process that a third rotating shaft drives a plurality of third shifting mechanisms on the third rotating shaft to synchronously rotate clockwise, the tennis balls entering the third collecting cylinder can be shifted up and move around the direction of the third rotating shaft under the shifting of a fifth shifting plate, and can reach the upper containing chamber; the sixth shifting plates fixedly connected to the right end of the first diaphragm plate can receive tennis balls shifted by the third rotary distribution mechanism and transfer the tennis balls into the upper accommodating chamber, and the subsequently shifted tennis balls can continuously enter the sixth shifting plates and enter the upper accommodating chamber along with the continuous rotation of the third rotary shaft; the first partition board is inclined in a left-high and right-low manner, so that tennis balls can smoothly reach the right end of the upper accommodating chamber, and collection operation of the tennis balls is facilitated.
