A table tennis ball picking machine

Abstract

A table tennis ball picking machine, which includes a body, an executive mechanism, an operating mechanism and a walking mechanism. There is a slender slideway; the actuator includes a front panel hinged at the front of the body, an inner flap hinged at the inside of the body, and a collection box at the rear of the body. The front panel is opened at the bottom and at the rear The box structure, the two sides of the body are provided with a sliding device that can move freely along the slideway, and the two sides of the rear part of the front fence are movably connected with the sliding device, so that the front fence can be turned up and down freely, and the inversion The rear end of the board is movably connected with both sides of the body, so that the inner turning board can be turned up and down freely. The invention at least has the advantages of high ball picking efficiency, large storage space, easy operation, low equipment cost and the like.

Description

technical field [0001] The invention relates to a ball picking machine, in particular to a table tennis ball picking machine. Background technique [0002] During table tennis training, table tennis balls are widely used, and picking up balls is often a cumbersome and repetitive task. At present, there are manual ball picking machines, electric ball picking machines, electric ball suction machines and other devices that are relatively common, but these three ball picking machines have their own disadvantages: the manual ball picking machine has a simple structure and is easy to operate, but the ball picking efficiency is low; The electric ball picking machine is composed of the control part and the sensing part, which is expensive, and when there are not only table tennis balls but also other sundries on the ground, the ball picking machine cannot distinguish, resulting in mispicking; the electric ball picking machine uses the principle of vacuum negative pressure The table...

AI Technical Summary

Problems solved by technology

There are many ball picking machines like this in the prior art, and its disadvantages are: (1) due to the fixed axis rotation of the ball picking board, the speed obtained by the table tennis balls is not enough to cross the bulge in the middle of the collection bin and directly fall into the rear storage area. (2) The initial movement direction of the table tennis ball is the normal direction of the collision point at the moment of impact, so the closer the ball is to the front opening of the collection bin in the ball picking area, the easier it is to be impacted and moved to the rear storage space, while the ball away from The farther the ball is, the more likely it is to deviate in its direction of motion, and the probability of colliding with the ball picking board and the inner wall of the collection bin and making a zigzag motion is greater, thus affecting the collection efficiency of table tennis balls; (3) table tennis balls in the ball picking area Most of the time, the speed and direction of the ball and the ball are not the same, and they will collide with each other, which will affect the ball entering the rear storage space, and even cross the ball picking board and pop out of the ball picking area

Furthermore, the size of the table tennis storage space at the rear of the collection bin depends to a certain extent on the height of the lateral bulge in the middle of the collection bin. Obviously, the higher the height of the lateral bulge, the larger the storage space for the balls. However, if the height of the lateral bulge Too high must make it more difficult for the ping pong balls to be knocked into the storage space at the back of the collection bin, and it is difficult to have both
