Description

Technical Field

[0001] The present invention relates to the technical field of basketball equipment, in particular to an automatic lifting basketball stand. Background Art

[0002] With the continuous popularization and development of basketball, basketball has become an indispensable sporting event in sports arenas, and basketball stands have become an indispensable sports equipment in stadiums. Existing basketball stands can be divided into fixed basketball stands, mobile basketball stands and wall-mounted basketball stands. People can choose the basketball stand that suits them according to different user groups and different usage scenarios.

[0003] Typically, gymnasiums are equipped with fixed, liftable basketball hoops. However, most gymnasiums are not solely for basketball. Due to their bulk and weight, the presence of the basketball hoops can become an obstacle during other sports or events, hindering the use of the gymnasium. Several solutions have been proposed in the prior art, such as Chinese invention patent CN2006100448.2 (published on November 22, 2006). The solution is a concealed basketball hoop, which utilizes a hydraulic rod, with a backboard fixed to the top of the hydraulic rod. The base, hoop, and backboard are all placed underground. Left and right cover plates with semicircular holes in the middle are positioned at corresponding locations on the ground, with covers provided at the holes. The hydraulic rods conceal the basketball hoop underground, which is then sealed with the cover plates. However, this basketball hoop also has certain limitations during use.

[0004] For example, in a gymnasium, various types of competitions and trainings, as well as various activities, are often held in the gymnasium, with a large flow of people. If the gymnasium is blocked by moving the cover, it is easy for trainees or participants to accidentally trip when other sports activities are carried out, causing unnecessary personal injuries. At the same time, the existing hidden basketball stand only lowers the basketball stand underground for hiding, and there is still a lot of space around the underground basketball stand, which is not fully utilized, resulting in low utilization of the underground space. Moreover, since the basketball stand is set underground, it is easy for dust to fall into it when it is frequently opened and closed, making it inconvenient to clean the underground and very easy to harbor dirt.

[0005] In view of this, in order to overcome the above technical problems, the present invention designs an automatic lifting basketball stand to solve the above technical problems. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that in the prior art, for gymnasiums that need to carry out various activities, fixed liftable basketball stands occupy the usable area of the gymnasium, and the internal space utilization rate of existing hidden basketball stands is low, and dirt and grime are easily hidden underground.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] The present invention provides an automatic lifting basketball stand, which includes a box body, a lifting element, a connecting arm, a backboard, a basket, a storage assembly, a closing assembly, an opening and closing assembly, a cleaning assembly and a control assembly. The box body is set underground and flush with the ground surface, so that the box body and the ground surface can be invisible. The lifting element is preferably an electric lifting column, and a hydraulic lifting column can also be used. The electric lifting column has a simpler structure and is more convenient to install, while the hydraulic lifting column has more stable lifting. The bottom end of the lifting element is welded and installed in the box body, the connecting arm is vertically welded to the top end of the lifting element, the backboard is welded and installed on the connecting arm, and the basket is hingedly installed on the backboard. The impact force generated by a 100 kg person when dunking is as high as 200,000 N-2 20000N. In order to prevent the basket from being damaged, the hinge of the basket is set to only be able to fold upward. The storage assembly is welded and installed in the box. The storage assembly is used to store basketballs and training personnel's items. The closing assembly is hinged and installed above the box. The closing assembly is used to achieve invisible fitting between the box and the ground. The opening and closing assembly is set at the connection between the closing assembly and the lifting element. The opening and closing assembly is used to keep the closing assembly and the box sealed and closed at all times. The cleaning assembly is welded and installed in the box. The cleaning assembly is used to clean and dry the basketball. The lifting element, storage assembly, closing assembly and cleaning assembly are all controlled by the control assembly and electrically connected to the control assembly.

[0009] Preferably, the storage assembly includes a partition, a basketball storage room, an item storage room, a conveying mechanism and an electric telescopic plate. The partition is welded to the bottom of the box body and is arranged at the rear end of the lifting element. The box body is divided into the basketball storage room and the item storage room by the partition. The item storage room is also the storage place for the backboard and the basket after they are lowered. Since a professional basketball team usually has 15 players, it should be ensured that at least everyone has a training basketball during basketball training, that is, a basketball team usually has at least 20 basketballs during training. Therefore, the basketball storage room is specially set up, the conveying mechanism is welded and installed in the basketball storage room, and the electric telescopic plate is welded and installed on the bottom of the item storage room.

[0010] Preferably, the transmission mechanism includes a goal channel, a ball outlet channel, an underground pipeline, a conveyor belt, a conveying ring, a sweeping plate, an arcuate plate and a telescopic element. The goal channel and the ball outlet channel are welded and installed on the inner wall of the box body. At the same time, an underground pipeline is opened at the bottom of the box body to connect the ball outlet channel and the goal channel to form a basketball transmission circuit. A motor is welded and installed below the conveyor belt. A plurality of conveying rings are welded and installed on the conveyor belt. The standard diameter of a basketball is 24.6 cm. The diameter of the conveying ring is set to 15-20 cm. An opening is opened on the side of the conveying ring. The sweeping plate is welded and installed below the goal channel and is located between the openings. At the same time, the sweeping plate forms an angle of 120-150° with the opening of the goal channel. Setting the angle of 120° makes the basketball slide into the goal channel faster. Setting the angle of 150° makes the basketball slide into the goal channel more smoothly. The arcuate plate is rotatably installed above the ball outlet channel by a rotating shaft. The telescopic element is welded and installed on the bottom of the ball outlet channel. The telescopic element is preferably an electric telescopic rod.

[0011] Preferably, the goal channel, underground conduit, and ball outlet channel are designed with a sloped arc shape. The inner walls of the housing, goal channel, underground conduit, and ball outlet channel are made of Teflon. Because basketballs cannot be transported solely through the interaction between them, the interior is designed with a sloped arc shape with a slope angle of 10-20°, which improves transport efficiency. Furthermore, since Teflon has a friction coefficient of only 0.04, this inner wall not only facilitates the sliding of the basketball within the goal channel, underground conduit, and ball outlet channel, but also, due to its excellent non-stick and wear resistance, this design prevents dirt from accumulating within the housing.

[0012] Preferably, a first pressure spring is welded and installed above the curved plate, and a pressure sensor is welded to the other end of the first pressure spring and welded to the inner wall of the box. The standard of the basketball air pressure is 0.48-0.62 bar. The pressure of the basketball applied to the curved plate is used to detect whether the air pressure value inside the basketball is normal. At the same time, a paint spray gun is welded and installed on the inner wall of the ball outlet channel to spray different colors of paint for basketballs with different pressures. Basketballs with normal air pressure, too low air pressure or too high air pressure are marked with different colors respectively.

[0013] Preferably, the closing assembly includes an invisible door, a hinge and an electric push rod. The invisible door is provided with two leaves. Because the hinge has the characteristics of strong installation security and easy installation, the two invisible doors are hinged to the two ends of the box opening through the hinge, and the electric push rods are respectively welded and installed on the inner walls at the other two ends of the box opening, which makes it more convenient to open and close the invisible door.

[0014] Preferably, the invisible door is made of aluminum alloy. The density of aluminum alloy is , which is about 1 / 3 of steel and lighter in weight. In particular, 7075 aluminum alloy is a cold-treated forged alloy, but its hardness is as high as 150HB, which better ensures the safety of trainees during training. At the same time, the advantage of the light weight of aluminum alloy also makes it more convenient to open and close the invisible door.

[0015] Preferably, the opening and closing assembly includes an opening and closing plate, a second pressure spring and an opening and closing slot, and a semicircular hole is respectively opened at the free end of the two invisible doors, the size of the semicircular hole matches the size of the part where the lifting element is flush with the box body, and the semicircular hole is located at the front end of the opening and closing slot, and the opening and closing plate is welded and installed in the opening and closing slot through the second pressure spring.

[0016] Preferably, the cleaning component includes a clean water tank, a sewage tank, a water pump, an atomizing nozzle, a cleaning brush, a water collecting tank, a blower, an electric heater and a drying pipe. The clean water tank is welded and installed in the box body and is located on one side of the lifting element. The sewage tank is welded and installed on the side of the clean water tank. The sewage tank is configured to be detachable. The water pump is welded and installed on the bottom of the clean water tank. The water pump is welded to the atomizing nozzle through a water pipe. The water pipe is configured to have multiple nozzles, and the atomizing nozzle is fixedly installed at each nozzle. The pressure value of the atomizing nozzle is set to 0.35-0.5 MPa, the atomization angle is set to 60°, the cleaning time is set to 10-20 min, and it is located above the underground pipeline. The cleaning brush is passed through The motor is rotatably installed above the telescopic element, and the speed of the cleaning brush is set to 200r / min-500r / min, thereby achieving the cleaning of the basketball. The bottom of the sewage tank is welded with the water pump and the water collecting tank through the water pipe, and is located below the underground pipeline. A plurality of water outlet holes are provided below the underground pipeline. The blower and the electric heater are welded and installed in the box in sequence and are located on the other side of the lifting element. Since basketball is not suitable for a long time in a high temperature environment, the heating temperature of the electric heater is set at 30-40°, and the drying time is set to 5-8min. The electric heater is welded to the drying pipe and is located above the underground pipe. There are multiple openings in the drying pipe.

[0017] Preferably, a rectangular baffle is welded to the ball outlet channel and the side of the ball outlet channel. The rectangular baffle ensures the stability of basketball transmission when the basket hooks the basketball on the transmission ring and when the telescopic element pushes the basketball onto the transmission ring.

[0018] The beneficial effects of the present invention are as follows:

[0019] The present invention uses the combined effects of the lifting element and the closing assembly to completely hide the basketball stand in the underground box. When the basketball stand is not in use, it does not occupy any space in the gymnasium and can ensure the safety of trainees. At the same time, the storage assembly is designed to accommodate basketballs and clothes, greatly improving the utilization rate of the hidden space of the basketball stand. A cleaning assembly is also provided, which, on the one hand, makes it difficult for dirt to accumulate in the box, and on the other hand, enables the cleaning and drying of the basketball.

[0020] 1. The automatic lifting basketball stand of the present invention is designed with the closing assembly. When the lifting element lowers the basketball stand into the underground box, the box is closed by the invisible door, thereby achieving complete concealment of the box from the ground. That is, there is no protruding cover that could cause people to accidentally trip and get injured, thereby increasing the usable space in the gymnasium.

[0021] 2. The automatic lifting basketball stand of the present invention utilizes the partition to divide the box into the basketball storage room and the item storage room, and the conveying mechanism and the electric retracting plate are fixedly installed in the basketball storage room and the item storage room respectively. During training, it is convenient not only for trainees to store and take out basketballs, but also for trainees to store and take out clothes, thereby realizing full utilization of the underground hidden space.

[0022] 3. An automatic lifting basketball stand of the present invention is designed with the cleaning component. On the one hand, the cleaning water tank and the sewage tank are fixedly installed on one side of the lifting element, the atomizing nozzle is set above the underground passage, and a rotating cleaning brush is provided, so as to achieve uniform cleaning of the basketballs stored in the underground passage. In addition, the sewage after cleaning the basketballs will flow into the water collecting tank through the water outlet opened below the underground pipe, and finally be pumped into the sewage tank by a water pump and discharged, so that it is not easy for dirt to accumulate in the box; on the other hand, the blower and the electric heater are fixedly installed on the other side of the lifting element, and a drying pipe with multiple nozzles is provided at the same time, so as to ensure that the cleaned basketballs are fully dried, that is, to ensure that the basketballs used by the trainers are clean, which better meets the training needs of the trainers.

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] Example 1: Figures 1 to 2As shown, an automatic lifting basketball stand includes a box body 1, a lifting element 2, a connecting arm 3, a backboard 4, a basket 5, a storage component 6, a closing component 7, an opening and closing component 8, a cleaning component and a control component. The box body 1 is set underground and flush with the ground surface, so that the box body 1 can be invisible from the ground surface. The lifting element 2 is set to multi-section lifting, which to a certain extent reduces the distance between the lowered basketball stand and the bottom surface, making it easy to store. The bottom end of the lifting element 2 is fixedly installed in the box body 1, and the connecting arm 3 is vertically fixedly connected to the top end of the lifting element 2. The backboard 4 is fixedly installed on the connecting arm 3, and the basket 5 is hingedly installed on the backboard 4. In order to prevent the impact force of the dunk action, the hinge of the basket 5 is set to only be able to be folded upward;

[0037] The storage assembly 6 is fixed in the box 1. The storage assembly 6 is used to store basketballs and trainers' items. At the same time, the storage assembly 6 is also the storage place after the backboard 4 and the basket 5 are lowered. The basketballs are lowered into the storage assembly 6 in the box 1 by the lifting element 2. The closing assembly 7 is hingedly installed above the box 1. The closing assembly 7 is used to achieve invisible fitting between the box 1 and the ground, so that the surface space is not occupied. The opening and closing assembly 8 is arranged at the connection between the closing assembly 7 and the lifting element 2. The opening and closing assembly 8 is used to keep the closing assembly 7 and the box 1 always sealed and closed before and after training of the trainers. The cleaning assembly is fixedly installed in the box 1. The cleaning assembly is used to clean and dry the basketball. The lifting element 2, storage assembly 6, closing assembly 7 and cleaning assembly are all controlled by the control assembly and electrically connected to the control assembly.

[0038] When a trainee is training basketball in a gymnasium, the control component and the trainee cooperate to open the closing component 7, and then the control component controls the lifting element 2 to drive the connecting arm 3, the backboard 4, and the basket 5 to rise simultaneously, and adjust them to a suitable height according to the trainee's needs. At the same time, the trainee can place his or her clothes in the storage component 6, and the control component controls the storage component 6 to transfer the basketball used for training. After the preparation is completed, the trainee manually closes the closing component 7 to continue basketball training.

[0039] When the trainer finishes training, the control assembly and the trainer cooperate to open the closure assembly 7. The trainer can then place the basketball after training into the storage assembly 6 for storage, and then control the cleaning assembly to clean and dry the stored basketball. The control assembly also facilitates the trainer to retrieve their clothes. The trainer then controls the control assembly to synchronously lower the lifting element 2, the connecting arm 3, the backboard 4, and the basket 5 into the storage assembly 6, and finally close the closure assembly 7. However, depending on the trainer's training situation and the usage of the training venue, the trainer can choose whether to lower the backboard 4 and basket 5 into the storage assembly 6.

[0040] Although the basketball stand in the prior art has realized automatic lifting, it is only for the purpose of being suitable for use by groups of different ages and heights. According to national standards, different age groups should use basketball stands with different basket heights. The basket height for adults is 3050mm, the basket height for middle school students is 2700mm, the basket height for grades 4-6 in elementary school is 2350mm, and the basket height for grades 1-3 in elementary school is 2050mm. Therefore, the prior art mainly realizes the lifting of basketball stands to meet the needs of different groups of people; however, the basketball stand is large in size and weight, occupies an area of the training ground, and when it is needed to be lifted, the basketball stand is not easy to lift. When the scene of the training ground changes, the basketball stand becomes an obstacle. Of course, there are also movable basketball stands and hidden basketball stands, but it is troublesome to move the movable basketball stands back and forth in the prior art, and the hidden basketball stands are hidden by moving the cover plate. This design is convenient to use and does not take up space, but it is troublesome to move the cover plate back and forth. For gymnasiums that need to frequently switch scenes, the cover plate on the ground can easily cause tripping accidents. Therefore, the automatic lifting basketball stand designed by the present invention realizes the invisible storage of the basketball stand, which is more convenient.

[0041] like Figures 3 and 4As shown, the storage assembly 6 includes a partition 61, a basketball storage chamber 62, an article storage chamber 63, a conveying mechanism 64 and an electric telescopic plate 65. The partition 61 is fixedly connected to the bottom of the box body 1, and the partition 61 is arranged at the rear end of the lifting element 2. The box body 1 is divided into the basketball storage chamber 62 and the article storage chamber 63 by the partition 61, that is, the basketball storage chamber 62 is used to store basketballs used for training, and the article storage chamber 63 is used to store the trainees' personal clothes. At the same time, the article storage chamber 63 is also the storage place for the backboard 4 and the basket 5. The conveying mechanism 64 is fixedly installed in the basketball storage chamber 62, and the conveying mechanism 64 realizes the conveyance of the basketball, which makes it more convenient for the trainees to take it. The electric telescopic plate 65 is fixedly installed at the bottom of the article storage chamber 63, and the electric telescopic plate 65 makes it more convenient for the trainees to retrieve the articles.

[0042] On the basis of the above embodiment 1, Figure 5 As shown, the transmission mechanism 64 includes a goal channel 641, a ball outlet channel 642, an underground pipe 643, a conveyor belt 644, a motor, a transmission ring 645, a sweeping plate 646, an arc plate 647 and a telescopic element 648. The goal channel 641 and the ball outlet channel 642 are fixedly mounted on the inner wall of the basketball storage chamber 62. At the same time, an underground pipe 643 is provided at the bottom of the box body 1 to connect the ball outlet channel 642 and the goal channel 641. This design forms a basketball transmission circuit, that is, the basketball enters from the goal channel 641 and is discharged through the ball outlet channel 642. A motor is fixedly mounted below the conveyor belt 644. The conveyor belt 644 is rotated by the motor to realize transmission. There are multiple transmission rings 645 installed, the diameter of the transmission ring 645 is smaller than the diameter of the basketball, and an opening is opened on the side of the transmission ring 645. The grasping plate 646 is fixedly installed below the goal channel 641 and is located between the openings. At the same time, it forms an angle of 120-150 degrees with the opening of the goal channel 641. Through this design, when the basketball is transmitted to the position of the grasping plate 646, it will directly slide into the goal channel 641 under the action of force. The arc plate 647 is rotatably installed above the ball outlet channel 642, and the telescopic element 648 is fixedly installed on the bottom of the ball outlet channel 642. The telescopic element 648 is used to push the basketball out and return it to the transmission ring 645 under the action of the arc plate 647 for transmission.

[0043] like Figure 5As shown, the goal channel 641, the underground pipe 643 and the ball outlet channel 642 are arranged to have a sloped arc shape, and the box body 1, the goal channel 641, the underground pipe 643 and the ball outlet channel 642 use Teflon inner walls. The goal channel 641, the underground pipe 643 and the ball outlet channel 642 form a transmission circuit for the basketball, but it is difficult to transmit the basketball only by the interaction force between the basketballs. Therefore, the interior is arranged to have a sloped arc shape, which improves the transmission efficiency to a certain extent. At the same time, the selection of such an inner wall, on the one hand, due to the low friction coefficient of Teflon material, it is more conducive to the sliding of the basketball in the goal channel 641, the underground pipe 643 and the ball outlet channel 642. On the other hand, since Teflon material has good non-stick and wear resistance, through this design, the box body 1 is not easy to hide dirt and grime. When cleaning, it can be cleaned by using a vacuum cleaner with a long flat suction head.

[0044] like Figure 5 As shown, a first pressure spring is fixedly installed above the curved plate 647, and the other end of the first pressure spring is fixedly connected to a pressure sensor, which is also fixedly connected to the inner wall of the box body 1. Through this design, when the telescopic element 648 pushes the basketball out, the basketball will exert a certain pressure on the curved plate 647, so that the pressure sensor can detect the pressure inside the basketball and promptly remind the training personnel to inflate or exhaust the basketball. At the same time, a three-color paint spray gun 68 is fixedly installed on the inner wall of the ball outlet channel 642, and different colors are sprayed on normal basketballs, over-inflated basketballs and under-inflated basketballs, which is convenient for training personnel to distinguish and handle them.

[0045] When the trainee needs to conduct basketball training, the control component controls the conveyor belt 644 to convey, and at the same time controls the telescopic element 648 to push the basketball to the ball outlet channel 642. Due to the obstruction of the arc plate 647, the basketball will fall on the conveyor ring 645 and be conveyed one by one under the action of the conveyor belt 644. The trainee can pick it up as needed; when the training is over, the trainee can place the trained basketball on the conveyor ring 645, and transmit it to the goal channel 641 through the control component, and cooperate with the action of the grab plate 646 to make the basketball slide into the goal channel 641 for storage, and this cycle is repeated.

[0046] like Figure 3 and Figure 7As shown, the closing component 7 includes an invisible door 71, a hinge 72 and an electric push rod 73. The invisible door 71 is provided with two leaves. Since the lifting element 2 is fixedly installed in the box body 1 and is continuously lifted and lowered, two invisible doors 71 are provided to facilitate the opening and closing of the box body 1. The two invisible doors 71 are hinged to the two ends of the opening of the box body 1 through the hinge 72. The installation is more secure and convenient using the hinge 72. The electric push rods 73 are fixedly installed on the inner walls at the other two ends of the opening of the box body 1. Through this design, when the invisible door 71 is opened, the control component controls the electric push rod 73 to push the invisible door 71 and the box body 1 can be opened with manpower.

[0047] like Figure 8 As shown, the invisible door 71 is made of aluminum alloy. Compared with other materials, aluminum alloy is lighter in weight but has a higher hardness and can bear a larger load. When the invisible door 71 is closed, the ground surface is level with the box body 1, thereby increasing the area of the training ground. Therefore, when the trainees are doing other training, they will inevitably step on this ground. The use of aluminum alloy with higher hardness can better ensure the safety of the trainees during training. At the same time, the advantage of aluminum alloy's light weight also makes it easier to open and close the invisible door 71.

[0048] like Figure 3 and Figure 8 As shown, the opening and closing assembly 8 includes an opening and closing plate 81, a second pressure spring 82 and an opening and closing slot 83. Semicircular holes are respectively provided at the free ends of the two invisible doors 71. When the lifting element 2 is raised for basketball training, the invisible door 71 needs to be closed to ensure the safety of the trainees. The diameter of the semicircular hole is equal to the diameter of the part where the lifting element 2 is flush with the box body 1, and the semicircular hole is located at the front end of the opening and closing slot 83. The opening and closing plate 81 is fixedly installed in the opening and closing slot 83 by the second pressure spring 82.

[0049] Through this design, when the lifting element 2 is raised and the invisible door 71 is closed, the opening and closing plate 81 is squeezed by the lifting element 2 and contracts into the opening and closing groove 83 under the action of the second pressure spring 82, and finally completely matches the semicircular hole, thereby ensuring that the closing component 7 and the box body 1 are always sealed and closed before and after the training of the trainees, thereby greatly protecting the safety of the trainees.

[0050] like Figures 3 to 6As shown, the cleaning assembly includes a cleaning water tank 91, a sewage tank 92, a water pump 93, an atomizing nozzle, a cleaning brush, a water collecting tank 96, a blower 97, an electric heater 98 and a drying pipe 99. The cleaning water tank 91 is fixedly installed in the box body 1 and is located on one side of the lifting element 2. The sewage tank 92 is fixedly installed on the side of the cleaning water tank 91. The sewage tank 92 is configured to be detachable, that is, the sewage after cleaning the basketball is discharged into the sewage tank 92, and the sewage tank 92 is disassembled to discharge the sewage. The water pump 93 is fixedly installed at the bottom of the cleaning water tank 91, and the water pump 93 is fixedly connected to the atomizing nozzle through a water pipe. The water pipe is configured to have multiple nozzles, and the atomizing nozzle is fixedly installed at each nozzle and is located above the underground pipeline 643. The basketball is sprayed with the atomizing nozzle Water mist flushing can achieve a more uniform washing of the basketball. The cleaning brush is installed above the telescopic element 648 through the rotation of the motor. The pressure value of the atomizing nozzle is set to 0.4 MPa, the atomization angle is set to 60 degrees, and the cleaning time is set to 15 minutes. When cleaning the basketball, the telescopic element 648 drives the cleaning brush to rise, and controls the rotation of the motor through the control component, thereby driving the cleaning brush to rotate to achieve washing of the basketball. The bottom of the sewage tank 92 is fixedly connected to the water pump 93 and the water collecting tank 96 through a water pipe, and is located below the underground pipe 643. A plurality of water outlets are opened below the underground pipe 643. The water after cleaning the basketball flows into the water collecting tank 96 through the water outlet and is pumped into the sewage tank 92 by the water pump 93.

[0051] The blower 97 and the electric heater 98 are fixedly installed in the box body 1 in sequence and are located on the other side of the lifting element 2. The electric heater 98 is fixedly connected to the drying pipe 99 and is located above the underground pipe 643. The drying pipe 99 is provided with multiple openings, thereby achieving more uniform drying of the basketball. When the basketball is cleaned and the water in the water collecting tank 96 is pumped into the sewage tank 92, the control component controls the blower 97 to extract air, and hot air is formed through the action of the electric heater 98. The heating temperature of the electric heater is set to 30°, and the drying time is set to 6 minutes. Finally, the air is discharged into the underground pipe 643 through the drying pipe 99 to dry the cleaned basketball, so that the basketballs used again by the training personnel are clean.

[0052] like Figure 10As shown, rectangular baffles 649 are fixedly mounted on the ball outlet channel 642 and on the sides of the ball outlet channel 642. The rectangular baffles 649 ensure the stability of the basketball during transmission when the catch 646 hooks the basketball on the transmission ring 645 and when the telescopic element 648 pushes the basketball onto the transmission ring 645. That is, the basketball will not deviate from its trajectory under the action of the rectangular baffles 649.

[0053] Example 2: Due to the different materials of basketballs, setting the cleaning time and drying time in Example 1 for ordinary leather basketballs can better achieve the cleaning and drying of the basketballs. For rubber basketballs, which are easier to clean, the pressure value of the atomizing nozzle can be set to 0.35 MPa, the cleaning time is 10 minutes, and the speed of the cleaning brush is set to 200 r / min to clean the rubber basketball. Finally, the heating temperature of the electric heater is set to 30°. At the same time, since the surface of the rubber basketball is smooth and easy to dry, the drying time is set to 5 minutes to complete the drying process of the rubber basketball.

[0054] Example 3: For a basketball made of fur material, it is heavy, easy to absorb water and sweat, and difficult to clean, so the pressure value of the atomizing nozzle can be set to 0.5 MPa, the cleaning time is 20 minutes, and the rotation speed of the cleaning brush is set to 500 r / min, so that the dirt on the fur basketball can be better removed. At the same time, since the fur basketball has a certain water absorption, the heating temperature of the electric heater is set to 35°, and the drying time is set to 8 minutes, thereby ensuring that the fur basketball is completely dried.

[0055] Normally, the lifting element 2 will bring the connecting arm 3, backboard 4 and basket 5 down to the box 1 and be hidden underground. When the trainer needs to conduct basketball training, the control component controls the electric push rod 73 to push the invisible door 71, and the invisible door 71 is opened by manpower, and then the lifting element 2 is controlled to rise. After the lifting element 2 is raised, the trainer can place personal clothes in the item storage chamber 63 to prevent damage or loss during training. At the same time, the control component controls the conveying mechanism 64 and the telescopic element 648 to convey the cleaned and dried basketballs one by one. The trainer can take the basketball according to the training needs. After a series of operations, the invisible door 71 can be manually closed. Finally, the control component adjusts the height to a suitable level and starts training. When the training is over, the trainer can open the invisible door 71 through the control component, and then slide the trained basketball through the conveying mechanism 64 and the picking plate 646 into the underground pipe 643 for cleaning and drying, and control the electric telescopic plate 65 to push the trainer's clothes up for easy retrieval. At the same time, the trainer can freely decide whether to lower the clothes for storage according to the training situation and the needs of the scene. When storage is needed, it can be retracted by controlling the control component.
