Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings and examples, which are simplified schematic drawings and illustrate only the basic structure of the invention in a schematic manner, and thus show only the constituents relevant to the invention.
As shown in fig. 1-6, a tennis ball collecting device comprises: a tennis ball collection device, comprising: the tennis ball storage barrel 16 is erected on the carrier 12 and the carrier 12, the rotating platform 17 is sleeved on the outer side of the storage barrel 16, and central shafts of the carrier 12, the storage barrel 16 and the rotating platform 17 are collinear;
the top of the storage barrel 16 is provided with an opening 8, a rod body 2 is arranged in the storage barrel 16, part of the rod body 2 extends out of the storage barrel 16 through the outlet 5, a buffer layer is arranged on the part of the rod body 2 extending out of the storage barrel 16, and the buffer layer is positioned right above the opening 8; the outer side wall of the rotating table 17 is provided with a plurality of slideways 15, each slideway 15 is arranged upwards in a spiral manner, the spiral hour-hand directions of each slideway 15 are the same, the surface providing centripetal force rotating along the slideways 15 for tennis balls is a spherical facing surface 10, the top outlet 5 of each slideway 15 points to the buffer layer on the rod body 2, the position of the outlet 5 is higher than the position of the opening 8, the inlet 13 of the slideway 15 close to the ground side is embedded with an anti-abrasion ball 11, and the bottom edge of each slideway 15 is provided with a guide collision ball 14; the self-rotation clockwise direction of the device when collecting the balls is opposite to the spiral clockwise direction of the slide way 15.
The illustrated part is a schematic configuration of the apparatus, and is merely a reference for positional relationship and connection of components, and does not relate to dimensions and sizes. The alignment of the central axes of the carrier 12, the bucket 16 and the turntable 17 is relatively stable to the apparatus. The buffer layer is positioned right above the opening, and tennis balls at the outlet 5 are intensively limited at the buffer layer and the area below the buffer layer. A prerequisite for tennis balls at outlet 5 to fall into opening 8 is that the height of outlet 5 is as high as possible above the height of opening 8.
When in use, the camera device 1 on the top of the device is matched with the moving or sensing device of the carrier 12 to serve tennis balls scattered on various places on the field. When the carrier 12 approaches the tennis ball, the rotating platform 17 on the carrier 12 starts to rotate or is always in a rotating state, and in consideration of energy consumption during rotation, the slide way 15 arranged outside the rotating platform 17 is made of plastic, the ball facing surface 10 of the slide way 15 is smoothened, and the kinetic energy loss of the ball during the rising in the slide way 15 is reduced. An arc-shaped guide plate 6 is arranged at an outlet 5 at the top end of the slide way 15, a tangent line of an arc-shaped free end of the guide plate 6 points to the opening 8 or a position right above the opening 8, namely, tennis balls climbing along the slide way 15 are finally guided into a storage barrel 16 in a rotating platform 17, a plurality of hemispherical protrusions 9 are arranged on a ball facing surface 10 at the top of the slide way 15, the protrusions 9 and a buffer layer can reduce the ball speed, and the moving direction of the tennis balls can be changed by the arrangement of the protrusions 9 and the arrangement of the guide plate 6. The hanging rope is tightened by the hanging pendent 7 of the buffer layer, and the moving range of the tennis ball and the kinetic energy of the tennis ball are greatly limited when the tennis ball impacts the area of the hanging rope 4. The pendant 7 is an elastic ball body, the pendant 7 cannot be damaged in the process of mutual collision, the quality and the volume are ensured, and blocking of tennis balls can be met.
The distance between the entrance 13 at the bottom of the ball-facing surface 10 of the slide way 15 and the ground is still 1-3cm, the cross section of the entrance 13 at the bottom of the slide way 15 is U-shaped, which is closer to the shape of a tennis ball, and can reduce the resistance when the tennis ball enters the entrance 13, and the thickness of the slide way 15 at the entrance 13 of the slide way 15 is the thinnest part in the thickness of the whole slide way 15, so that when a tennis ball enters the entrance 13, the bottommost part of the slide way 15 is likely to touch the ground, and therefore, the anti-abrasion ball 11 is embedded on the entrance 13 at the near ground side of the slide way 15. In order to prevent tennis balls from being collected into the slide ways 15 and being thrown away by the edges of the slide ways 15, the guiding collision beads 14 are arranged at the edges (the thickness of the edges of the slide ways 15 is relatively thin, the thickness is relatively sharp, the additional guiding collision beads 14 can reduce the safety factor and the structural strength of the whole device, namely the thinner slide ways 15 can be deformed when contacting a tennis net), namely when the ball cannot enter the current entrance 13, the guiding collision beads 14 collide with the tennis balls, and the tennis balls can be guided out of the next entrance 13 after collision.
Except for the inlet 13 at the bottom of the ball-facing surface 10 on the slideway 15, the slideways 15 at the other positions form a closed pipeline, and the inner cavity side wall of the pipeline is the ball-facing surface 10. In the attached drawings of the specification, the parts of the slide ways 15 except the inlet 13 and the outlet 5 are all of pipeline structures, gaps between the slide ways 15 (gaps arranged in the length direction of the side walls of the pipelines) can facilitate observation of tennis balls by personnel, and the tennis balls can be timely stopped and adjusted when congestion occurs in the slide ways 15.
When the bucket 16 is collected to the point that it is nearly full, the apparatus stops and the bucket 16 can be lifted out of the apparatus by pulling on the lever 2, i.e., the collecting part and the storing part of the apparatus are easily separated. The operation is more convenient when the ball is taken. The tennis balls in the storage barrel 16 can be collected again after being poured out and placed in the inner cavity area of the rotating platform 17 again.
In another preferred embodiment, only the slideway 15 is partially distinguished, the slideway 15 is of a telescopic structure and is arranged in a groove arranged on the side wall of the rotating platform 17, and when the rotating platform 17 rotates for more than 10-15 circles, the slideway 15 can extend out of the groove for collecting and conveying tennis balls.
The rotation direction of the device is opposite to the spiral direction of the slide way 15, air flow conveying can be formed when the device rotates, and the slide way 15 is used for assisting certain ascending air flow besides pushing the tennis balls.
In light of the foregoing description of the preferred embodiment of the present invention, it is to be understood that various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
