A body-free mobile roller ball picker

Abstract

The invention provides an attachment-free mobile roller ball picker, which relates to the technical field of ball pickers and solves the problem that the distance between the ball picker and the ground cannot be well controlled. When pushing to pick up the ball, it is easy to generate a lot of friction noise; when picking up the ball, only the inertia of the push can make the ball enter the ball picking seat, and the head of the ball picking seat is easy to form a problem of accumulation when picking up balls in batches. A body-free mobile roller ball picker, comprising a frame body, a rotating shaft A and a knocking pin structure; a collection structure is installed on the frame body, and a moving structure is installed on the frame body. Because a ball is installed at the four corners of the bottom surface of the bottom plate, and when the ball is in contact with the ground, the distance between the bottom plate and the ground is 0.3cm, so that the vertical limit of the bottom plate can be realized, and the bottom plate and the ground can also be placed Friction makes a lot of noise.

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
