阅读说明：本技术 乒乓球自动练习装置 (Automatic table tennis exercise device ) 是由 禹福连 于 2020-03-03 设计创作，主要内容包括：本发明涉及乒乓球自动练习装置,采用自动收集掉落到地面的乒乓球后将其供给到投球机的循环式结构,练习过程中无需一一收集散落在四处的乒乓球,可以独自进行有效的练习。本发明的乒乓球自动练习装置包括：长方形的乒乓球台,以沿着宽度方向垂直设置的球网为基准,区分为位于一侧的第一场区及另一侧的第二场区,基于支撑下端的支撑杆而形成高度；投球机,设置在第一场区的末端部,将依次供给的乒乓球发射到所述第二场区；收集台,设置在第一场区的末端部,收集移送或掉落的乒乓球并供给到投球机；围栏部,由水平设置在地面上的下导板和向设置在下导板的上方的网兜构成,形成乒乓球台内嵌的空间,限制乒乓球脱离的范围,引导落在地面上的乒乓球的移动方向；送风部,由对掉落到乒乓球台下方的地面上的乒乓球送风而使其移动到设置在乒乓球台下方的下导板的一侧末端部；及移送部,吸入被移送到下导板的一侧末端部的乒乓球而将其移送到收集台。并且,其特征在于,提供一种乒乓球自动练习装置,沿着向第一场区和第二场区的中心部分倾斜的底面引导板,在导槽设置乒乓球移送装置,从而将掉落到乒乓球台下部底面的乒乓球(A)移送到收集台。(The invention relates to a table tennis automatic practice device, which adopts a circulating structure for automatically collecting table tennis balls falling on the ground and supplying the table tennis balls to a pitching machine, so that the table tennis balls scattered around are not required to be collected one by one in the practice process, and the table tennis automatic practice device can independently and effectively practice. The table tennis automatic practice device of the invention comprises: a rectangular table tennis table divided into a first field area on one side and a second field area on the other side based on a net vertically arranged in a width direction, and having a height formed based on a support bar supporting a lower end; a pitching machine which is arranged at the end part of the first field area and launches the table tennis balls supplied in sequence to the second field area; a collecting table which is arranged at the end part of the first field area, collects the transferred or dropped table tennis balls and supplies the table tennis balls to the pitching machine; the fence part consists of a lower guide plate horizontally arranged on the ground and a net bag arranged above the lower guide plate, forms an embedded space of the table tennis table, limits the range of table tennis separation and guides the moving direction of the table tennis falling on the ground; an air supply part which supplies air to the table tennis falling on the ground under the table tennis table and moves the table tennis to the end part at one side of a lower guide plate arranged under the table tennis table; and a transfer unit for sucking the table tennis balls transferred to one end of the lower guide plate and transferring the table tennis balls to the collecting table. Further, the table tennis automatic practice apparatus is characterized in that a table tennis transfer means is provided in the guide groove along a bottom surface guide plate inclined toward the center portion of the first field and the second field, and table tennis balls (a) dropped on the bottom surface of the lower portion of the table tennis table are transferred to the collecting table.)
