And another method is to make a smooth supply of the ball to the vertical throwing device, and another method is to drill a plurality of long holes in the inside of the container inclined to store the vertical ball to the vertical throwing device by the sensor By supplying the ball, it provides the ability to store a large amount of golf ball in the basement of the designated batter, and shortens the length of the ball discharge pipe and allows the vertical throwing device to discharge the ball at a right angle so that the feeder is underground Can be installed at a minimum height, and the height of the ball being thrown to the plate at the bottom of the vertical throwing device It will help in providing that it can be changed.

The golf ball transfer device of the conventional golf practice range is hit by a golf ball hit at the designated batting hit the target attached to the net and then fall into the guide groove formed by the diagonal line and flows naturally by the water flowing into the guide groove The ball is moved upwards by the bucket elevator installed to fit the height of the number of floors of the golf practice range, and the ball released from the bucket elevator is supplied by the number of floors of the designated batter by the distribution pipe, and then moved to the horizontal conveying device. The ball is supplied to the air outlet of the air supply, followed by the ball to the vertical throwing device.

However, the ball conveying device of the golf practice range has the following problems, the first is that when the bucket elevator installed to fit the number of floors of the ball housed in the locating device does not like to fly to the conventional bucket elevator using a chain As a result, there is a drawback that the golfer located at the plate at the batter cannot be focused by this noise due to the noise of the continuously operated machine, and the machine is complicated and difficult to assemble. . Secondly, the ball distributed by the distribution pipe moves to the horizontal conveying device, and then the ball introduced into each ball discharging pipe installed in the designated turn is finally moved to the vertical throwing device.

However, when the ball inserted into the lower end of the ball discharge pipe is moved to the vertical throwing device, another ball in the rear may be over half of the vertical throwing device, which hinders the operation of the vertical throwing device. There is a problem that can not be smoothly supplied to the resin ball holder because it can not only accommodate two to four balls in the interior. Third, there is a problem that the height of the turn at the plate is increased when the discharge pipe and the vertical transfer device buried underground in the old golf ball transfer device is already installed.

Fourth, whether the golfer will tee shot (holding and hitting the ball with the tee to make it more distant from the ground) or shot at the plate with the ball on the ground. The selection is made by using the selected selection button. At this time, the stroke distance of the piston of the drive unit is set by the selection operation of the selection button. However, this is a problem that can not be hit at various heights because the ball is simply placed on the ground and only two motions are supported.

The present invention has been made in order to solve the above-mentioned conventional problems, the first of which is to raise the collected golf ball to be operated in a low noise by using a conveyor belt to supply a designated batter as a flexible timing belt of the golfer Improve concentration and secondly, install a cam roller spaced from the end of the inclined air outlet pipe in the designated batter's basement so that it can be operated without interruption from the ball supplied with the vertical throwing device. By drilling a plurality of long holes in the inclined inside and supplying the balls to the vertical throwing device by a sensing sensor while storing several balls with the long holes, a large amount of golf balls can be stored underground in a designated plate. And thirdly, the vertical throw where the length of the ball discharge pipe buried underground is shortened and the golf ball is discharged upward. Teeth can be rotated at right angles so that the feeder can be installed at a minimum height in the basement. Fourth, the drive of the vertical thrower can change the height of the ball thrown into the plate at the bottom. Its purpose is to provide you with the ability to practice.
