Description

Technical Field

[0001] The present invention relates to the technical field of track and field training equipment, and specifically relates to an auxiliary device for track and field training. Background Art

[0002] The shot put is one of the throwing events in track and field. It has a significant effect on enhancing physical fitness, especially on developing the strength of the torso and upper and lower limbs. During the training process, the shot put thrown out needs to be collected with time and effort before the throwing training can be carried out again, which affects the training effect of the shot put event. The landing area of the shot put field generally uses a soft ground such as sand or turf. After the shot put is thrown, it will stick to sand or grass sections and needs to be cleaned before the next throw, further affecting the effective training time.

[0026] A fourth guide plate in a shape of "eight" is arranged on the top of the bottom plate.

[0027] The conveying component includes two symmetrically arranged guide pipes that are in rolling cooperation with the shot put and have a certain inclination angle. One side of the high end of the guide pipe is close to one side of the part of the conveyor belt above the shot put field, and one side of the low end of the guide pipe is close to the throwing area;

[0028] A number of pairs of support rods are fixedly connected below the guide pipe. A pair of support rods below the high end of the guide pipe are fixedly connected with a limit post that is clamped and matched with the lower ear plate. A limit plate is arranged at the top of one end of the guide pipe close to the throwing area.

[0029] When the present invention is actually used: When the shot put throwing training starts, after throwing the rated number of shot puts, the throwing stops. After the shot put hits the turf on the top of the flipping plate, dirt and grass segments will adhere to its surface. Start the driving motor to drive the flipping plate to tilt downward to the lower side of the throwing area and dock with the input end of the collection box, and then the motor stops to fix the flipping angle. Under the action of gravity, the shot puts roll into the collection box in sequence and enter the cleaning box through the conveying pipe. At this time, after the output port of the cleaning box blocks a plurality of shot puts in the cleaning box under the restriction of the spring clamping plate and the side wall of the corresponding hopper, start the driving motor to flip again, and the flipping plate starts to flip upward to reset to the horizontal. During the reset process, two brush rollers are driven to rotate towards each other through the first linkage component to clean the surface of the shot put, and at the same time, the push rod is driven to reciprocate to make the piston type air box continuously blow air into the cleaning box to enhance the cleaning effect of the surface of the shot put. The garbage removed enters the garbage bin through the through hole below. While cleaning, the reset process of the flipping plate also drives the conveying mechanism to operate through the second linkage component, and conveys the hopper upward. When the hopper blocking the shot put moves above the output end of the collection box, the shot put falls into the lower hopper under the action of gravity and overcoming the resistance of the spring clamping plate. In turn, the next shot put overcomes the resistance of the spring clamping plate and falls into the next hopper. The hopper conveys the shot puts to above the ground in sequence. When the limit post catches the lower ear plate and the hopper continues to rise, the bottom plate is opened, and the shot put rolls out under the action of gravity and rolls towards the side close to the throwing area through the guide pipe for convenient continued throwing training use.

[0030] Among them, when the flipping plate tilts downward, it drives the second ratchet wheel to rotate. The second ratchet wheel is not meshed with the first ratchet wheel, and since the second gear tooth block is an elastic structure that can be telescoped, the second ratchet wheel can rotate continuously without driving the first gear to rotate, so it does not drive the conveying mechanism to operate. Only when the flipping plate resets to the horizontal, the first ratchet wheel meshes with the second ratchet wheel and drives the conveying mechanism to operate. In addition, the overall support of the flipping plate is completed by the first support plate, the second support plate and the support roller. When the flipping plate tilts downward to collect the shot put, the support roller moves downward into the support box under the action of pressure and rises during the reset.

[0031] The beneficial effects of the present invention are:

[0032] 1. By tilting the tipping plate, the shot put in the landing area can be recovered as a whole and conveyed to one side of the throwing area after being cleaned, which greatly saves the time and physical strength for picking up and cleaning the shot put and effectively improves the effect of shot put training;

[0033] 2. The cleaning mechanism of the present invention is linked with the tipping support mechanism without an additional power device, and through the proportional relationship designed by the first linkage component, the cleaning work of the shot put is well realized while the tipping plate is turned up and reset;

[0034] 3. The conveying mechanism of the present invention is linked with the tipping support mechanism without an additional power device, and through the proportional relationship designed by the second linkage component, the shot put is conveyed above the ground and docked with the conveying component while the tipping plate is turned up and reset;

[0035] 4. The docking of the conveying mechanism of the present invention with the conveying component is automatically completed through structural design without manual intervention or an additional power device;

[0036] 5. Only through the driving motor of the tipping support mechanism, the present invention automatically completes the functions of shot put collection, cleaning, and conveying while tilting and resetting. The structural design is skillfully matched, and the economy and applicability are good. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The upper and lower sides of the hopper 602 are both open structures. One side of the bottom edge of the hopper 602 close to the conveyor belt 601 is hinged with a bottom plate 603. On both sides of the bottom plate 603 far from its hinged end, lower ear plates 604 are symmetrically arranged. Corresponding to the lower ear plates 604, upper ear plates 605 are symmetrically arranged above both sides of the hopper 602. A tension spring 606 is fixedly connected between the lower ear plate 604 and its corresponding upper ear plate 605. A V-shaped fourth guide plate 607 is arranged on the top of the bottom plate 603. The conveying component 7 includes two symmetrically arranged guide pipes 701 that are in rolling cooperation with the shot 11 and have a certain inclination angle. One side of the high end of the guide pipe 701 is close to the conveyor belt 601 and is located above the shot field 10. One side of the low end of the guide pipe 701 is close to the throwing area 8. A number of pairs of support rods 702 are fixedly connected below the guide pipe 701. A pair of support rods 702 located below the high end of the guide pipe 701 are fixedly connected with a limit post 703 that is engaged with the lower ear plate 604 in a clamping manner. A limit plate 705 is arranged at the top of one end of the guide pipe 701 close to the throwing area 8.

[0057] During actual use: When the shot put training starts, after a rated number of shot puts 11 are thrown, the throwing stops. After the shot puts 11 hit the turf on the top of the turning plate 2, the surfaces will stick with soil and grass segments. The driving motor 304 is started to drive the turning plate 2 to tilt downward to one side of the throwing area 8 and dock with the input end of the collection box 401, and then the motor stops to fix the turning angle. Under the action of gravity, the shot puts 11 roll into the collection box 401 in sequence and enter the cleaning box 501 through the conveying pipe 403. At this time, after the output port of the cleaning box 501 blocks a plurality of shot puts 11 in the cleaning box under the restriction of the spring clip 510 and the corresponding side wall of the hopper 602, the driving motor 304 is started to turn again, and the turning plate 2 starts to turn upward to reset to the horizontal. During the reset process, two rotary brushes 506 are driven to rotate towards each other through the first linkage component to clean the surface of the shot put, and at the same time, the push-pull rod 509 is driven to reciprocate to make the piston type air box 507 continuously blow air into the cleaning box 501 to enhance the cleaning effect of the surface of the shot put 11. The cleaned garbage enters the garbage bin 505 through the through hole 504 below. During the cleaning, the reset process of the turning plate 2 also drives the conveying mechanism 6 to operate through the second linkage component 12 to convey the hopper 602 upward. When the hopper 602 blocking the shot put 11 moves above the output end of the collection box 501, the shot put 11 falls into the lower hopper 602 under the action of gravity and overcoming the resistance of the spring clip 510. In turn, the next shot put 11 overcomes the resistance of the spring clip 510 and falls into the next hopper 602. The hopper 602 conveys the shot puts 11 to above the ground in sequence. When the limit post 710 catches the lower ear plate 604, when the hopper 602 continues to rise, the bottom plate 603 is opened, and the shot put 11 rolls out under the action of gravity and rolls to one side close to the throwing area 8 through the guide pipe 701 for convenient continued throwing training use.

[0058] Among them, when the turning plate 2 tilts downward, it drives the second ratchet wheel 1202 to rotate. The second ratchet wheel 1202 is not engaged with the first ratchet wheel 1201. Since the tooth blocks of the second gear 1202 are elastic structures that can be telescoped, the second ratchet wheel 1202 can rotate continuously without driving the first gear 1201 to rotate, thus not driving the conveying mechanism 6 to operate. Only when the turning plate 2 returns to the horizontal position, the first ratchet wheel 1201 engages with the second ratchet wheel 1202 and drives the conveying mechanism 6 to operate. In addition, the overall support of the turning plate 2 is completed by the first support plate 301, the second support plate 307, and the support roller 305. When the turning plate 2 tilts downward to collect the shot put 11, the support roller 305 moves downward into the support box 306 under pressure and rises during the reset.
