[0024] The utility model discloses a sports equipment storage and release device, which improves the convenience of picking up balls and can also facilitate the unified storage and release of balls after picking up the balls.

[0025] 1. Push the storage and release device. One end of the mobile trolley is swung and connected to a ball collecting drum. As the ball collecting drum rotates, a pick-up and release gap is reserved between a plurality of tensioning elastic strips arranged at intervals on the outer circumference of the ball collecting drum. When it rotates above the ball, the pick-up and release gaps between the tensioning elastic strips are squeezed by the ball, causing the tensioning elastic strips to deform and change the size of the pick-up and release gaps. The ball can enter the storage cavity formed by the tensioning elastic strips on the outer circumference of the ball collecting drum. When the external force is lost, the tensioning elastic strips on the outer circumference of the ball collecting drum restore the original pick-up and release gaps under the action of their own elastic force, and the storage cavity of the ball collecting drum is confined within the ball collecting drum.

[0026] 2. When the balls in the ball collecting drum are collected and the balls need to be released, the ball collecting drum only needs to be swung upward by rotating the flip plate connected to the mobile trolley until the ball collecting drum is located on the upper part of the drop bin of the mobile trolley. At this time, the outer sides of the opening and closing side panels on both sides of the ball collecting drum are squeezed by the extrusion wheels inside the drop bin, and the opening and closing side panels move closer to the fixed side panels on the inside. At this time, the stretching distance between the two ends of the tensioning elastic strip is shortened, and the tensioning elastic strip becomes loose, so that the balls can fall out of the storage cavity formed by the tensioning elastic strip on the outer periphery of the ball collecting drum and fall into the storage box in the drop bin of the mobile trolley.

[0027] 3. Store the spheres in a storage box. When you need to take out the spheres, you only need to pull out the storage box to take out the spheres in batches. BRIEF DESCRIPTION OF THE DRAWINGS

Fig. 9 As shown, the side section of the ball collecting drum 4 is a Reuleaux triangle b; that is, the structure of the fixed side plate 41 and the opening and closing side plate 42 is also a Reuleaux triangle b.

[0045] Specifically, a material taking trough connected to the material dropping bin 12 is provided on the side of the mobile vehicle 1 , and a storage box 13 that can move in and out of the material dropping bin 12 is movably embedded in the material taking trough, and the opening on the top of the storage box 13 corresponds to the material dropping bin 12 .

[0046] Specifically, the side wall of the material bin 12 of the mobile trolley 1 is rotatably connected with an extrusion wheel 2 which is arranged oppositely. Specifically, the extrusion wheel 2 is rotatably connected to the mounting seat at the upper end of the side wall of the material bin 12 via a rotating shaft 21. The wheel surface of the extrusion wheel 2 can roll and press against the outer side surface of the opening and closing side plate 42 of the ball receiving rotating drum 4 flipped onto the material bin 12 to relax the tensioning elastic strip 43. Furthermore, the spacing between the opening and closing side plates 42 arranged oppositely in the ball receiving rotating drum 4 is smaller than the spacing between the material bin 12.

[0047] Specifically, the rotation axis of the ball collecting drum 4 intersects with the travel track of the moving trolley 1. Preferably, the rotation axis of the ball collecting drum 4 is relatively perpendicular to the travel track of the moving trolley 1.

[0048] Specifically, when the swinging flip plate 33 reaches the front end of the moving cart 1, the outer peripheral surface of the ball collecting drum 4 contacts the ground; when the swinging flip plate 33 reaches both sides of the dropping bin 12 of the moving cart 1, the ball collecting drum 4 is located at the upper part of the dropping bin 12, and the ball collecting drum 4 can be at least partially embedded in the dropping bin 12, and the opening and closing side plates 42 of the ball collecting drum 4 can roll in contact with the circumference of the extrusion wheel 2, and the extrusion wheel 2 can squeeze the opening and closing side plates 42 closer to the fixed side plates 41.

[0049] More specifically, the tensioning elastic strip 43 adopts an elastic rope or elastic strip in the prior art. The selection of profiles is not described here one by one, as long as the elastic tension can meet the extrusion and storage of the ball 5, the specific elastic value and tension parameters can be adjusted according to the actual use requirements. And the spacing between adjacent tensioning elastic strips 43 can be adjusted according to the size of the ball 5 actually stored, and the threading spacing of the tensioning elastic strips 43 on the ball receiving drum 4. Example 2

[0050] like Figure 3-Figure 7 , Fig.10 As shown, a sports equipment storage and release device comprises a mobile trolley 1, a material drop bin 12 is reserved on the top of the mobile trolley 1, a flip plate 33 is swingably connected to one end of the mobile trolley 1, a ball collecting drum 4 is rotatably connected to the flip plate 33, and a flip handle 34 extending outward is also provided on the outer side of the flip plate 33. Fig.10 As shown, the side profile of the ball collecting drum 4 is a curved triangle c. That is, the three corners of the regular triangle are curved. Specifically, one end of the flip plate 33 arranged opposite to each other is rotatably connected to the outer side of the frame 11 of the mobile trolley 1 through the respective rotating shafts 3, and a rotation limiting slide groove 31 is also provided on the outer side of the frame 11, and a protrusion slidably embedded in the rotation limiting slide groove 31 is provided on the flip plate 33; and a limiting pin hole 311 is provided on the frame 11 and the flip plate 33 respectively. When collecting the balls 5 scattered on the ground, the flip plate 33 can be flipped outward, so that the outer periphery of the ball collecting drum 4 contacts the ground, and the positioning pin is inserted or screwed into the limiting pin hole 311 on the same axis of the frame 11 and the flip plate 33 at this time, so as to realize the limiting between the frame 11 and the flip plate 33, so as to facilitate the promotion and rotation when collecting the balls 5 and the stability of the material collection. When the balls 5 need to be released, the positioning pin in the limiting pin hole 311 is taken out to release the flip plate 33. However, it is not limited to this. When collecting the balls 5 scattered on the ground, if you do not want to lock the positions of the flip plate 33 and the frame 11, you can also collect the balls 5 on the ground by the downward pressure of the ball collecting drum 4 itself, so there is no need to additionally limit the relative position between the frame 11 and the flip plate 33 by limiting the positioning pins.

[0051] Specifically, the ball collecting drum 4 includes a second rotating shaft 331 rotatably connected to the flip plate 33, a pair of oppositely arranged fixed side plates 41 are fixedly sleeved on the second rotating shaft 331, an opening and closing side plate 42 is also arranged at intervals on the outer side of the fixed side plate 41, and an elastic spacer is also arranged between the adjacent fixed side plates 41 and the opening and closing side plates 42. The opening and closing side plates 42 are movably sleeved on the second rotating shaft 331, and a plurality of tensioning elastic strips 43 are ring-connected on the oppositely arranged opening and closing side plates 42; a storage cavity is formed between the fixed side plates 41 and the fixed side plates 41, and a pick-up and release gap 431 is reserved between adjacent tensioning elastic strips 43. The plurality of tensioning elastic strips 43 are independently penetrated and fixed on the outer periphery of the oppositely arranged opening and closing side plates 42, and are arranged at intervals in a harp string-like manner; and the plurality of tensioning elastic strips 43 are respectively and movably penetrated through the corresponding mounting through holes on the fixed side plates 41. Furthermore, the installation gap between the adjacent tensioning elastic strips 43 on the fixed side plate 41 and the opening and closing side plate 42 is smaller than the diameter of the ball 5 to be received, but larger than the radius of the ball 5 to be received. Fig.10 As shown, the side section of the ball receiving drum 4 is a curved triangle c (i.e., the three corners of the regular triangle are curved sides). That is, the fixed side plate 41 and the opening and closing side plate 42 are curved triangles c. Fig.10 As shown, the structure of the ball collecting drum 4 facilitates the contact and force between the ball 5 and the ball collecting drum 4, which is beneficial for the ball 5 to squeeze the pick-and-place gap 431 on the ball collecting drum 4 to collect the ball.

[0052] Specifically, a material taking trough connected to the material dropping bin 12 is provided on the side of the mobile vehicle 1 , and a storage box 13 that can move in and out of the material dropping bin 12 is movably embedded in the material taking trough, and the opening on the top of the storage box 13 corresponds to the material dropping bin 12 .

[0053] Specifically, the side wall of the material bin 12 of the mobile trolley 1 is rotatably connected with an extrusion wheel 2 which is arranged oppositely. Specifically, the extrusion wheel 2 is rotatably connected to the mounting seat at the upper end of the side wall of the material bin 12 via a rotating shaft 21. The wheel surface of the extrusion wheel 2 can roll and press against the outer side surface of the opening and closing side plate 42 of the ball receiving rotating drum 4 flipped onto the material bin 12 to relax the tensioning elastic strip 43. Furthermore, the spacing between the opening and closing side plates 42 arranged oppositely in the ball receiving rotating drum 4 is smaller than the spacing between the material bin 12.

[0054] Specifically, the rotation axis of the ball collecting drum 4 intersects with the travel track of the moving trolley 1. Preferably, the rotation axis of the ball collecting drum 4 is relatively perpendicular to the travel track of the moving trolley 1.

[0055] Specifically, when the swinging flip plate 33 reaches the front end of the moving cart 1, the outer peripheral surface of the ball collecting drum 4 contacts the ground; when the swinging flip plate 33 reaches both sides of the dropping bin 12 of the moving cart 1, the ball collecting drum 4 is located at the upper part of the dropping bin 12, and the ball collecting drum 4 can be at least partially embedded in the dropping bin 12, and the opening and closing side plates 42 of the ball collecting drum 4 can roll in contact with the circumference of the extrusion wheel 2, and the extrusion wheel 2 can squeeze the opening and closing side plates 42 closer to the fixed side plates 41.

[0056] More specifically, the tensioning elastic strip 43 adopts the elastic rope or elastic strip in the prior art. The selection of profiles will not be described one by one here, as long as the elastic tension can be achieved to meet the extrusion and storage of the ball 5, the specific elastic value and tension parameters can be adjusted according to the actual use requirements. And the spacing between adjacent tensioning elastic strips 43 can be adjusted according to the size of the ball 5 actually stored, and the threading spacing of the tensioning elastic strips 43 on the ball receiving drum 4. However, it is not limited to this. In other embodiments, one or more support beams can be set between the relatively fixed side plates 41 to improve the stability of the ball receiving drum 4. Example 3

[0057] On the basis of Example 1 or Example 2, Figure 8 As shown in FIG. 1 , the side section of the ball receiving drum 4 is a circle a. That is, the shapes of the fixed side plate 41 and the opening and closing side plate 42 are as follows: Figure 8 The circle a shown. When the ball collecting drum 4 collects the balls 5 scattered on the ground, the flip plate 33 can be flipped outward, so that the outer periphery of the ball collecting drum 4 contacts the ground, and the positioning pin is inserted or screwed into the limiting pin hole 311 of the frame 11 and the flip plate 33 on the same axis at this time, so as to achieve the limiting between the frame 11 and the flip plate 33, which is convenient for pushing and rotating when collecting the balls 5 and the stability of collecting materials. When it is necessary to release the balls 5, the positioning pin in the limiting pin hole 311 is taken out to release the flip plate 33. Example 4

[0058] On the basis of Embodiment 1 or Embodiment 2, in other embodiments, the side section of the ball receiving drum 4 may also be other polygonal structures. Furthermore, for example, the side section of the ball receiving drum 4 may be a polygonal structure with an inwardly concave arc edge, and the inwardly concave depth of the inwardly concave arc edge is less than the radius of the ball 5 to be received. Fig.11 As shown, a polygonal structure d with concave arc edges.

[0059] Working principle:

[0060] When the ball collecting operation on the ground is to be realized, the storage and release device is pushed to move toward the position where the balls are scattered, and one end of the mobile trolley is swung and connected to a ball collecting drum, which faces downward, contacts the ground, and is rollingly connected to the flip plate of the mobile trolley. When the storage and release device is pushed, as the ball collecting drum rotates, a pick-up and release gap is reserved between a plurality of tensioning elastic strips arranged at intervals on the outer circumference of the ball collecting drum. When it rotates to above the ball, the pick-up and release gaps between the tensioning elastic strips are squeezed by the ball, causing the tensioning elastic strips to deform, thereby changing the size of the pick-up and release gaps, so that the ball can enter the storage cavity formed by the tensioning elastic strips on the outer circumference of the ball collecting drum. When the external force is lost, the tensioning elastic strips on the outer circumference of the ball collecting drum restore the original pick-up and release gaps under the action of their own elastic force, thereby confining the storage cavity of the ball collecting drum within the ball collecting drum.

[0061] When the balls in the ball collecting drum are completely stored and it is necessary to release the balls in the ball collecting drum, it is only necessary to swing the ball collecting drum upward by rotating the flip plate connected to the mobile trolley until the ball collecting drum is located on the upper part of the dropping bin of the mobile trolley. At this time, the outer sides of the opening and closing side plates on both sides of the ball collecting drum are squeezed by the extrusion wheels inside the dropping bin, and the opening and closing side plates move closer to the fixed side plates on the inner side. At this time, the stretching distance between the two ends of the tensioning elastic strip is shortened, and the tensioning elastic strip becomes loose. The balls can fall out of the storage cavity formed by the tensioning elastic strip on the outer periphery of the ball collecting drum and fall into the storage box in the dropping bin of the mobile trolley.

[0062] The spheres are stored in a storage box. When the spheres need to be taken out, only the storage box needs to be pulled out to take out the spheres in batches.

[0063] Based on the ideal embodiment of the utility model, through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the invention. The technical scope of the invention is not limited to the content in the specification, and must be determined according to the scope of the claims.
