Description

  The present invention relates to a golf ball collecting apparatus that collects golf balls scattered on the ground in a driving range where a golf shot is practiced by, for example, a free-form.

  It is effective to practice golf at a driving range that is wide and long enough for shots such as a driver, iron, and approach on an actual golf course. is set up. As a result of various shots by the practitioner at the driving range, the golf balls are widely scattered in the ground of the driving range, and the scattered golf balls are collected, cleaned and supplied to the practitioner again. Has become. However, collecting the golf balls scattered in a wide ground, it takes a lot of time and labor to pick up each one manually, so the collecting devices shown in the following patent documents etc. Is used.

  That is, for collecting golf balls scattered in the ground, a ball collecting device proposed by a patent document or the like is used. For example, in the ball collecting device disclosed in Patent Document 1, a large number of elastic disks are arranged on an axis at intervals slightly smaller than the ball diameter, and the balls sandwiched between the disks are rolled by rolling on the ground. It is removed by a plate and placed in a collection basket provided in front of the shaft. The unmanned pickup truck shown in Patent Document 2 includes a ball pick-up mechanism, and this ball pick-up mechanism is energized by a coil spring or holds a ball between elastic disks and removes the held ball. Thus, the balls are collected on a chute having comb teeth arranged between the disks.

Japanese Patent Laid-Open No. 7-80101 Japanese Utility Model Publication No. 63-34461

  However, in the ball collecting apparatus of Patent Document 1, the distance between the disks is slightly smaller than the diameter of the balls so that the balls are sandwiched between the disks. However, it will spread somewhat outward. Therefore, especially when collecting the balls in a place where the balls are densely packed, if the balls are sandwiched between all the elastic disks arranged in the left-right direction, the force of sandwiching the balls will cause the elastic disk to move toward the center. The balls are concentrated in proportion to the number of the sheets, and the ball sandwiched between the elastic disks on the center side is sandwiched with a very large force. If it does so, it becomes impossible to remove the sandwiched ball by the comb-like plate, and it becomes impossible to sandwich and collect a new ball, and the collector cannot be sandwiched and the collecting device moves forward and drops the ball. Sometimes.

  In addition, in the unmanned pickup truck of Patent Document 2, since the coil springs are mounted between the outer sides of the adjacent disks so that the distance between the disks arranged in a pair to sandwich the balls becomes narrow, the combination can be performed so as to sandwich the balls. It is possible to hold and collect balls between a pair of discs. However, since the ball is not sandwiched between the gaps between the adjacent disks that are provided with the coil spring and sandwich the coil spring, the ball may be missed, for example, in a place where the balls are dense.

  That is, in the conventional collecting devices shown in these patent documents and the like, a plurality of balls when golf balls scattered on the ground are densely adjacent to each other in the left-right direction are collected. There are cases where it is difficult to pinch them separately and pick them up reliably. If the ball cannot be picked up in this way, it must be collected again manually, which is extremely troublesome.

  Therefore, the present invention was created in view of various circumstances that existed in the past, and the purpose of the present invention is when golf balls widely scattered on the ground are adjacent to each other and gathered together. However, it is an object of the present invention to provide a golf ball collecting device that securely clamps and picks them up and prevents them from being lost.

In order to solve the above-described problems, in the present invention, the main body frame 2 including the wheels 5 that can run on the ground and the collecting shaft 12 supported on the rear portion of the main body frame 2 are paired on the left and right. A plurality of sandwiching portions 15 formed by arranging an excess ball exclusion disk 14 having a smaller diameter corresponding to the diameter of the golf ball B compared to the diameter of the sandwiching disk 13 between the elastic sandwiching disks 13 arranged in an opposing manner. The ball collecting mechanism 10 formed in an array and the lower end edge are close to the ground surface, and the spacing width is not smaller than the diameter of the golf ball B corresponding to each of the holding portions 15, and the support stay portion from the main body frame 2. The ball alignment mechanism 20 including a plurality of ball alignment plates 21 arrayed and supported by 23, and the golf ball B brought to the upper position by the rotation of the holding portion 15 from the holding portion 15 to the discharge guide plate 32 To integration by detached, characterized in that a collecting box 40 provided on the body frame 2 in front of the ball collection mechanism 10.
In the pinching portion 15 of the ball collecting mechanism 10, the sandwiching disks 13 that are combined in a pair to form the pinching portion 15 between the adjacent pinching portions 15 are bent to expand on either side of the adjacent pinching portion 15. It can be configured by arranging two sandwiched discs 13 on the other side, with two spaced apart from each other.
In addition, the pinching portion 15 in the ball collecting mechanism 10 includes one pinching disk 13 and two pinching discs 13 spaced apart from each other from one side end of the collecting shaft 12 to the other side end. In addition, a plurality of first, second, and third sandwiching disks 13 are sequentially arranged so as to arrange one sandwiching disk 13, and the inner sandwiching disk 13 in the even-numbered sandwiching section 15 The odd-numbered sandwiching portion 15 and the outer sandwiching disc 13 are shared, and the odd-numbered sandwiching portion 13 inside the sandwiching portion 15 and the even-numbered sandwiching disc 13 are arranged close to each other, and golf between them It can be configured that a bending interval is set so as to allow bending due to outward expansion when the ball B is sandwiched.
The surplus ball exclusion disk 14 is formed in a disk shape having a diameter that is substantially the same as the diameter of the golf ball B compared to the diameter of the sandwiching disk 13, and has a collecting shaft at a substantially central position in the sandwiching section 15. 12 can be provided.
The support stay portion 23 of the ball alignment mechanism 20 is provided on the left and right side portions 24 connected to the left and right portions of the main body frame 2 so as to be positioned on the front side of the sandwiching portion 15, and the left and right support plates 25 are suspended. The support member 26 is horizontally mounted between the lower portions, and the support pieces 27 in which the mounting grooves 28 of the lower opening are formed at the front and rear are fixed to the lower surface of the left and right support plates 25 and the lower surface of the support member 26 at a predetermined interval. The mounting groove 28 can be configured such that an alignment support bar 29 on which the ball alignment plate 21 is aligned and fixed can be mounted and fixed.
The ball alignment plate 21 has a substantially trapezoidal shape when viewed from a side surface having an inclined edge close to the outer peripheral edge of the sandwiching portion 15 at the rear portion, and is arranged in a hanging shape with a width of a predetermined alignment interval by the support stay portion 23. The ball alignment plate 21 can be formed by forming front and rear connection support grooves 22 corresponding to the front and rear mounting grooves 28 of the support piece 27 in a substantially L shape when viewed from the side.
The alignment support bar 29 is in the form of a male threaded rod, and the ball alignment plate 21 is sandwiched between a plurality of screwed nuts and arranged and fixed at a predetermined interval, and the nuts are inserted into the mounting grooves 28 of the left and right side portions 27. It can be configured by stopping and fixing.

In the golf ball collecting apparatus according to the present invention configured as described above, the golf ball B scattered on the ground surface is caused to roll forward by rolling the pinching portion 15 of the ball collecting mechanism 10 on the ground. When it reaches the position, the golf ball B is aligned and positioned between the ball alignment plates 21 in the ball alignment mechanism 20, and when the clamping portion 15 reaches the golf ball B, it is sandwiched by the left and right pair of elastic clamping discs 13. . When the sandwiched golf ball B is brought upward along with the rotation of the sandwiching portion 15, the discharge guide plate 32 rides on the golf ball B and is removed from the sandwiching portion 15 and is directly guided and accumulated in the collection box 40. .
The sandwiching disks 13 arranged in a face-to-face manner in the sandwiching portion 15 of the ball collecting mechanism 10 sandwich the golf ball B by its elastic action, and when sandwiched, the sandwiching disc 13 expands outwardly in a bent shape, but adjacent sandwiching portions. 15, the clamping disks 13 on one side are separated from each other by a bending interval, and by using one clamping disk 13 in common on the other side of the adjacent clamping parts 15, there is no gap between the adjacent clamping parts 15. Further, the sandwiching gap formed by the counter-shaped sandwiching disc 13 that sandwiches the golf ball B is continuously arranged, and the golf ball B that is densely arranged side by side on the ground surface is sandwiched without being missed.
Further, the surplus ball removing disk 14 in the clamping part 15 prevents a plurality of parallel clampings along the radial direction of the golf ball B sandwiched between the opposing clamping disks 13 of the clamping part 15. The golf ball B is prevented from falling off due to the excessive elastic bending action of the golf ball B, and the golf balls B are securely held one by one along the peripheral direction of the holding disk 13.
The support stay portion 23 of the ball alignment mechanism 20 positions and arranges the ball alignment plate 21 at a position in front of the pinching portion 15 in the ball collection mechanism 10, and a large number of golf balls B scattered on the ground surface as the vehicle travels forward. The golf balls B are aligned in accordance with the positions of the sandwiching portions 15 so that the golf balls B are securely sandwiched by the respective sandwiching portions 15.
The ball alignment plate 21 is positioned at a predetermined position corresponding to the holding portion 15 by being nut-attached to the alignment support bar 29 having a male screw rod shape by the connection support groove 22, and the mounting groove of the support piece 27 of the support stay portion 23. The alignment support bar 29 is inserted into 28, and the ball alignment plate 21 is securely connected to and supported by the support stay 23 via the alignment support bar 29 by fastening with a nut.

  Since the present invention is configured as described above, for example, when collecting the golf balls B widely scattered on the ground in order to supply the golf balls B again to the practitioner in a free-type golf driving range. They can be collected automatically by running forward on the ground surface. Also, even in a crowded state where the golf balls B are next to each other and arranged side by side on the left and right, they are securely pinched and picked up separately. Does not occur.

  In other words, in the present invention, a plurality of sandwiching portions 15 are formed by disposing an excess ball excluding disk 14 between the body frame 2 that can run on the ground and the elastic sandwiching disk 13 that is disposed opposite to the collecting shaft 12. A ball collecting mechanism 10 having a plurality of ball aligning plates 21 arranged at the front of the ball collecting mechanism 10 and supported at an interval width corresponding to each of the holding portions 15 and having a lower end edge close to the ground surface. This is because the alignment mechanism 20 and the collection box 40 for collecting and collecting the golf balls B from the pinching portion 15 with the discharge guide plate 32 are provided. As a result, even the golf balls B that are gathered together on the ground surface and are densely packed can be efficiently accumulated and accommodated in the collection box 40 without being picked up and picked up separately.

  Further, the pinching portion 15 of the ball collecting mechanism 10 is composed of elastic pinching discs 13 that are arranged in pairs on the left and right sides, so that the golf balls B on the ground surface can be pinched separately and arranged adjacent to each other. Even if one of the sandwiching discs 13 is expanded outwardly between the sandwiching portions 15, the sandwiching operation in the sandwiching gaps in the other adjacent sandwiching portions 15 is not hindered. A plurality of golf balls B are combined with the alignment action by the ball alignment mechanism 20 and can be separated and captured separately.

  The adjacent arrangement of the sandwiching portions 15 is such that the two sandwiching discs 13 are separated from one another on the opposite side of the sandwiching disc 13 constituting the sandwiching portion 15 by a bending interval with the other adjacent sandwiching portions 15. On the other side, since one clamping disk 13 that is common to other adjacent clamping parts 15 is arranged, the adjacent clamping parts 15 are arranged continuously without any unnecessary gaps. A plurality of adjacent sandwiching portions 15 can be configured with an efficient arrangement by reducing the number of disks 13.

  Since the surplus ball removing disk 14 disposed in the pinching portion 15 has a small diameter corresponding to the diameter of the golf ball B compared to the diameter of the pinching disk 13, when the golf ball B is pinched by the pinching disk 13, the diameter Two or more golf balls B are not sandwiched in the direction. That is, for example, when the golf ball B is pushed into the center side of the sandwiching disc 13 to sandwich the golf ball B, the peripheral portion of the sandwiching disc 13 is greatly expanded, so that the golf ball B cannot be sandwiched at the same edge portion. The sandwiched golf ball B is not dropped. In addition, since the plurality of golf balls B are not sandwiched in the radial direction of the sandwiching disk 13 but are sandwiched along the peripheral direction, they can be sequentially sandwiched along the peripheral direction when rotating with forward travel of the sandwiching portion 15. Can be processed continuously.

  The support stay portion 23 in the ball alignment mechanism 20 has a support member 26 mounted horizontally between the left and right support plates 25 suspended from the left and right side portions 24 connected to the main body frame 2, and is mounted on the lower surfaces of the left and right support plates 25 and the support member 26. Since the alignment support bar 29 on which the ball alignment plate 21 is aligned and fixed is attached and fixed to the fixed support piece 27, the ball alignment plate 21 arranged corresponding to the clamping portion 15 can be easily arranged and fixed. A mounting groove 28 having a downward opening is formed in the support piece 27 at the front and back thereof, and a ball alignment plate 21 is formed in which the connection support groove 22 corresponding to the mounting groove 28 is formed in a front and rear cutout in a substantially L shape. Since it is connected to the support piece 27 via the alignment support bar 29, it can be properly aligned and fixed.

  In addition, the alignment support bar 29 has a male threaded rod shape, and the ball alignment plate 21 is sandwiched and fixed by the alignment support bar 29 by a plurality of pairs of nuts. In addition to being able to adjust, the ball alignment plate 21 can be firmly supported via the alignment support bar 29 by sandwiching and fixing the support piece 27 with this nut.

And a surplus ball removing board 14 disposed between the holding parts 15 so as to have a smaller diameter corresponding to the diameter of the golf ball B than the diameter of the holding disk 13. Further, the wheel 5 diameter and the pinching portion 15 diameter are set so that the holding portion 15 is grounded to the ground surface together with the above-described wheel 5 so as to maintain the main body frame 2 substantially horizontally.

  A plurality of clamping portions 15 are provided on the collecting shaft 12 by a pair of clamping discs 13 on the left and right sides, and the distance between the pair of clamping discs 13 is slightly smaller than the golf ball B diameter, for example, 40 mm. The width is set. The sandwiching disc 13 itself has elasticity that expands outward when the golf ball B is sandwiched. The golf ball B is sandwiched by the elasticity, for example, a polycarbonate resin having a thickness of about 5 mm. It is formed by. Of course, the forming material is not limited to this, and is formed transparent if necessary.

  In the sandwiching part 15 composed of a pair of sandwiching disks 13 that are combined in pairs, the distance between the adjacent sandwiching parts 15 is a narrow interval where the golf ball B does not enter, and the adjacent pair of sandwiching disks 13. Each of them is set to a width interval that does not hinder the expansion when the golf ball B is sandwiched, for example, about 7 mm. In this way, the golf ball B is clamped at substantially the same position by the sandwiching discs 13 in the adjacent sandwiching portions 15, so that even if the golf ball B bends outward and expands, it is sandwiched in another adjacent sandwiching portion 15. The disks 13 are prevented from buffering each other (see FIG. 3).

  The sandwiching disks 13 shown in the drawing, which are combined in a pair to form the sandwiching part 15 between the sandwiching parts 15 adjacent to each other, are assumed to share one sandwiching disk 13 in the adjacent sandwiching part 15, that is, Only one of the sandwiching discs 13 facing each other when sandwiching the golf ball B flexes outwardly so that the golf ball B is resiliently sandwiched, and a plurality of sandwiching portions 15 are provided for the number of golf balls B to be sandwiched. A small number of sandwiching disks 13 can be arranged and configured.
