Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of baseball training, and in particular to an automatic baseball pitching device. BACKGROUND

[0002] The baseball pitching device is a special device for assisting baseball training and entertainment, and the core function is to simulate the pitching action of a pitcher to provide a stable target for the batter or the ball passer. It mainly includes two types of manual and automatic, the manual device is simple in structure, and is mainly driven by manpower (such as spring power storage), which is suitable for beginners to familiarize with the ball sense; the automatic device is the mainstream type, which is powered by motor, air pressure or hydraulic pressure, which can not only accurately adjust the pitching speed (usually 10-160km / h) and angle, but also simulate different pitches such as straight ball and curve ball. This kind of device is widely used in baseball training camps, school teams and family practice scenes, and its advantage is that it can avoid the fatigue and instability of manual pitching, and help users to improve the reaction speed and hitting accuracy.

[0003] However, in the prior art, the baseball pitching device generally needs to be manually adjusted before pitching when adjusting the pitching angle or arc, for example, the new multifunctional electric baseball pitching machine disclosed in the publication No. CN106422269B. After a large amount of training, the athlete unintentionally becomes familiar with the pitching rules, which reduces the training effect on the rapid reaction ability and instantaneous judgment ability after a large amount of training. Some products control random pitching through a controller, but this pitching method essentially just increases some pitching points, and this flexible pitching method will cause the adjusting device to be damaged due to the recoil force of the pitching in the instant, which is not conducive to the long-term use of the equipment.

shaft 2 23 drives the full gear 1 24 and the half gear 1 25 to rotate, at the same time, the full gear 2 27 and the rotating shaft 1 0 26 drive the half gear 2 28 to rotate, the half gear 1 25 first drives the full gear 3 210 to rotate clockwise, then the rotating shaft 3 29, the belt pulley 1 21 1 and the transmission belt 1 21 2 drive the belt pulleys 2 1 13 on both sides to rotate, so that the middle distance of the stepless speed change wheels 217 on the left becomes smaller, and the middle distance of the stepless speed change wheels 217 on the right becomes larger, conversely, when the half gear 1 25 is disengaged from the full gear 3 210, the half gear 2 28 is engaged with the full gear 3 210, so that the full gear 3 210 rotates reversely, then the middle distance of the stepless speed change wheels 217 on the left becomes larger, and the middle distance of the stepless speed change wheels 217 on the right becomes smaller, so that the rotating speed of the ball-throwing wheels 14 on both sides changes all the time when the servo motor 22 is powered on, at the same time, when the rotating shaft 3 29 rotates clockwise, the bevel gear 2 515 and the bevel gear 1 514 drive the rotating shaft 8 512 to rotate counterclockwise, then the belt pulley 4 51 1 and the transmission belt 2 51 0 drive the belt pulley 3 59 to rotate counterclockwise, and then the rotating shaft 7 56 drives the full gears 5 57 on both sides to rotate counterclockwise, through the cooperation with the arc-shaped rack 58, the rear end of the ball-throwing tube 1 1 is raised, conversely, when the rotating shaft 3 29 rotates counterclockwise, the full gear 5 57 rotates clockwise, through the cooperation with the arc-shaped rack 58, the rear end of the ball-throwing tube 1 1 is lowered, when the baseball is disengaged from the rotating shaft 4 214, the wedge block 414 and the electrode sheet 1 410 are reset by the springs 3 415 on both sides and the spring 2 412 in the middle, the servo motor 22 is powered off, the rear end of the ball-throwing tube 1 1 no longer moves, through the cooperation of the rotary speed regulation mechanism 2, the control mechanism 4 and the angle adjusting mechanism 5, when the baseball slides in the upper part of the ball-throwing tube 1 1, the rotating speed of the ball-throwing wheels 14 on both sides changes, then the speed of the baseball and the degree of rotation of the baseball are adjusted, at the same time, the inclination angle of the rear end of the ball-throwing tube 1 1 changes, this adjustment process occurs after the baseball is put into the ball-throwing tube 1 1 and before the baseball is launched, and the whole process is automatically adjusted, compared with the traditional adjustment mode of the player adjusting in advance, there is no need for human intervention, it is more convenient to use, and the adjustment is completed before the launch,When the baseball rolls between the two sides of the pitching wheel 14, the two sides of the pitching wheel 14 quickly push the baseball to the inner rear end horizontal section of the pitching tube 11, so that the air pressure in the inner rear end of the pitching tube 11 increases rapidly, the protective cover 17 is pushed away, the baseball is sent out, and at the moment when the air pressure in the inner rear end of the pitching tube 11 increases rapidly, a part of the airflow enters the inside of the sliding tube 33 through the air inlet 31 and the conduit one 32, extrudes the limiting column 35 and the clamping block 36 to clamp the left full gear five 57, so that the rotating shaft seven 56 cannot rotate, and then the rotating shaft eight 512 and the rotating shaft three 29 cannot rotate, finally synchronously make the two sides of the driving seat 216 cannot move up and down, through the cooperation of the pitching mechanism 1 and the limiting mechanism 3, after adjusting the speed, rotation speed and angle of the pitching, the rotation speed adjusting mechanism 2 and the angle adjusting mechanism 5 are in the locked state at the moment of pitching, which can prevent the trajectory from deviating due to the recoil force when pitching, so that the player can not misjudge the situation, and can protect the rotation speed adjusting mechanism 2 and the angle adjusting mechanism 5 from vibrating at the moment of pitching, thereby improving the service life of the pitching equipment, the gas entering the inside of the sliding tube 33 enters the inside of the air chamber 42 through the conduit two 43, drives the reciprocating wire rod 45 to rotate through the wind wheel 44, and then drives the sliding chamber 48 to reciprocate in the inside of the pitching tube 11 through the driving block 46 and the connecting seat 47, finally adjusts the height of the wedge block 414 exposed in the inside of the pitching tube 11, so that the time of the baseball contacting the wedge block 414 is different each time, thereby making the time of the servo motor 22 being powered on different, and finally making the time of each adjustment different, through the cooperation of the limiting mechanism 3 and the control mechanism 4, the time of the rotation speed adjusting mechanism 2 and the angle adjusting mechanism 5 adjusting the pitching tube 11 is different each time, which can more simulate the randomness of the pitcher's pitching, so that the pitching equipment can more realistically simulate the pitcher's pitching, and further exercise the reaction speed of the baseball player.
