Body-attachment-free movable roller ball picker

Abstract

The invention provides a body-attachment-free moving roller ball picker, relates to the technical field of ball pickers, and solves the problems that the distance between a ball picking seat and the ground cannot be well controlled, and a large amount of friction noise is easily generated when the ball picking seat is pushed to pick balls after being in contact with the ground; and the problems that during ball picking, balls can only enter the ball picking base through pushing inertia, and accumulation is prone to being formed at the head end of the ball picking base during batch ball picking. The body-attachment-free moving roller ball picker comprises a frame body, a rotating shaft A and a knocking pin structure; a collecting structure is installed on the frame body, and a moving structure is installed on the frame body. Due to the fact that the four corners of the bottom end face of the bottom plate are each provided with one ball, and the distance between the bottom plate and theground is 0.3 cm when the balls make contact with the ground, vertical limiting of the bottom plate can be achieved, and the situation that the bottom plate rubs with the ground to generate a large amount of noise can be avoided.

Description

technical field [0001] The invention belongs to the technical field of ball picking devices, and more specifically relates to a body-free moving roller ball picking device. Background technique [0002] When training in the table tennis room, a large number of table tennis balls are needed for use. The table tennis balls tend to roll all over the ground and need to be manually bent down to pick them up, which is time-consuming and laborious. However, ordinary table tennis ball picking tools need to be pulled up and down by hands The tool picks up the ball, and the tool is manually driven to move as a whole, which puts a greater burden on the arm, and the arm is more likely to feel tired, which affects the efficiency of picking up the ball. [0003] For example, the application number: CN201810891709.3, the invention discloses a table tennis ball picker, which includes a ball storage box, a fixed seat, a rotating shaft, a roller, a sliding cylinder, a ball picking seat, a sli...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a body-free mobile roller ball picker to solve the problem that the above-mentioned device cannot control the distance between the ball-picking seat and the ground well, when the ball-picking seat After contact with the ground, it is easy to generate a lot of friction noise when pushing to pick up the ball at this time; moreover, the above application can only push the ball into the ball picking seat due to the inertia of the above application when picking up the ball. The end position is easy to form accumulation; finally, the above application is easy to collect the dust and other residues on the ground into the ball picking seat in the process of picking up the ball, but cannot automatically realize the problem of removing the residue in the process of picking up the ball
