3. Advantageous effects

Compared with the prior art, the utility model has the beneficial effects that:

(1) the utility model provides a ball picker, wherein a bell mouth of the ball picker is used for contacting balls scattered on the ground in a large area. When picking up table tennis and ocean ball, the ball picking up personnel hold the middle barrel body by hand, align the lower end of the bell mouth with the small ball and press downwards, because the motor drives the blades to rotate at high speed, a stronger suction force is formed, the small ball is sucked into the middle barrel from the lower end of the bell mouth, the small ball slides upwards along the middle barrel and meets a boss connected with the barrel body, due to the action of gravity, the small ball slides into the transparent ball receiving barrel along the boss, after the collected small ball is filled in the ball receiving barrel, the knob of the ball receiving barrel is screwed down, the small ball is arranged in the barrel in order, and when the small ball in the ball receiving barrel is poured into a frame for storing the small ball, the collection is completed. In the whole collection process, the ball picking personnel do not need to bend down, and can collect the small balls scattered on the field, so that the labor intensity is reduced, and the collection efficiency can be improved.

(2) The utility model provides a small ball picker, wherein a ball receiving cylinder is used for collecting small balls scattered in a field, the size of the inner diameter of the ball receiving cylinder can be selected to be different, and the length of the ball receiving cylinder can be adjusted. If only need collect the table tennis, change the model of a ball receiving section of thick bamboo, fix on well section of thick bamboo through the screw thread, pull down the inner wall section of thick bamboo, can accomplish the extension of a ball receiving section of thick bamboo and adjust, the table tennis slides down into transparent ball receiving section of thick bamboo along the boss, after the ball receiving section of thick bamboo that collects was full of, unscrew the knob of a ball receiving section of thick bamboo, the bobble is neatly arranged in a section of thick bamboo, pours the bobble in the ball section of thick bamboo into the frame of depositing the bobble, accomplishes and collects. In the whole collecting process, the small balls with different sizes can be collected, the length of the ball receiving cylinder can be adjusted at will, and the small balls with different quantities can be contained, so that the labor intensity is reduced, the labor efficiency is improved, and a plurality of small balls can be contained.

(3) The utility model provides a small ball picker, wherein a filter screen of the small ball picker is used for preventing small balls sucked into a middle cylinder from entering a fan port along a hose. If table tennis and ocean ball are sucked into the middle cylinder from the bell mouth, the small ball does not fall into the ball receiving cylinder from the middle cylinder due to errors, but continues to slide upwards along the middle cylinder, meets the obstruction of the filter screen, and falls into an adjacent small cylinder due to impact rebound so as to enter the ball receiving cylinder. In the whole collecting process, a ball picking person only needs to hold the middle cylinder body by hand, walk on the field and align the bell mouth with the small balls, so that the small balls scattered on the field can be collected, and the condition that the small balls are blocked in a fan due to overlarge suction force is avoided.

(4) The utility model provides a small ball picker, wherein a dust filter bag of the small ball picker is used for receiving sucked dust and impurities. When the table tennis ball collecting device is used for collecting table tennis balls falling on the ground, dust on the ground is easy to absorb into the barrel due to light weight, and impurities enter the dust filter bag along the middle cylinder and the hose, so that the dust is prevented from being accumulated in the fan. In the whole collection process, impurities are not accumulated inside the fan, and the fan can be cleaned only by disassembling and cleaning the dust filter bag.
