Technical Field

[0001] The utility model relates to the technical field of plastic runways, in particular to an EPDM particle recovery device for a mixed plastic runway. Background Art

[0002] The plastic track is also known as the all-weather track for athletics. It has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to the athletes' speed and technology, effectively improving sports performance and reducing the rate of falls. The plastic track is made of EPDM and other materials. It has certain UV resistance and aging resistance and is internationally recognized as the best all-weather outdoor sports field floor material.

[0003] For example, a new EPDM granular plastic track with announcement number CN217203462U comprises, from bottom to top, a concrete base layer, an EPDM granular plastic cushion layer, and a rubber granular surface layer. The EPDM granular plastic cushion layer consists of a reinforcing mesh filled with EPDM granules, and a drainage layer is provided at the bottom of the reinforcing mesh. This utility model has the following advantages and effects: a reinforcing mesh is provided within the EPDM plastic cushion layer, and the EPDM granules are filled within the reinforcing mesh. The reinforcing mesh is crisscrossed, securing the EPDM granules and preventing them from falling off or cracking under sunlight or rain erosion. This enhances the strength of the EPDM plastic track and increases its service life, making it particularly suitable for paving uneven surfaces such as ramps.

[0004] The above patent can enhance the strength of the EPDM plastic track and increase its service life. However, excessive EPDM particles will be used when laying the EPDM plastic track. After the construction is completed, these EPDM particles need to be recycled. The existing recycling method is generally through manual cleaning and centralized collection. This method consumes a lot of manpower, and after collection, the sand and gravel particles mixed in the EPDM particles need to be removed, which is a cumbersome operation.

[0005] Therefore, we proposed an EPDM particle recovery equipment for mixed plastic tracks to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1 - Figure 3 A device for recovering EPDM particles for a hybrid plastic track comprises a vehicle body 1 and wheels 4 rotatably mounted on both sides of the vehicle body 1. A movable structure 2 is mounted at the front end of the vehicle body 1. The movable structure 2 comprises a fixed shell 21 fixedly mounted at one end of the vehicle body 1. A grounding block 22 is slidably connected to the lower end of the fixed shell 21. A spring 23 is fixedly mounted between the grounding block 22 and the fixed shell 21. A sweeping assembly 5 is mounted inside the grounding block 22. A recovery bin 3 is fixedly mounted at one end of the vehicle body 1.

[0023] In this embodiment: when using the device to recover excess EPDM particles on the plastic runway, the device can be driven on the plastic runway, and the grounding block 22 at the lower end is made to fit with the plastic runway through the action of spring 1 23, and the sweeping component 5 is started to sweep and recover the excess EPDM particles. The hybrid plastic runway EPDM particle recovery equipment can ensure that the front end of the EPDM particle recovery mechanism is always in contact with the ground through a simple structure, which can better recover EPDM particles, is more practical, and is easy to operate.

[0024] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 2 - Figure 4 A fixed block 24 is fixedly installed at the lower end of the grounding block 22, and the sweeping assembly 5 includes a mounting block 51 fixedly installed on the side wall of the grounding block 22. A motor 52 is fixedly installed in the mounting block 51, and a rotating rod 53 is fixedly installed at the output end of the motor 52, which can drive the rotating rod 53 to rotate through the motor 52.

[0025] The rotating rod 53 is rotatably installed between the inner walls of the grounding block 22. A number of sweeping blocks 54 are fixedly installed at equal intervals on the side walls of the rotating rod 53. The sweeping blocks 54 are in contact with the side walls of the fixed block 24. When the rotating rod 53 rotates, it can drive the sweeping blocks 54 to rotate and sweep the EPDM particles along the side walls of the fixed block 24 into the fixed block 24.

[0026] A movable rod 11 is rotatably installed between the interior of the vehicle body 1 and the fixed block 24 , and a conveyor belt 12 is commonly sleeved between the two movable rods 11 , through which the EPDM particles can be further transported to the rear end.

[0027] Movable rods 14 are rotatably installed on both sides of the interior of the vehicle body 1, and a filter belt 15 is commonly sleeved between the two movable rods 14. A filter screen 13 is fixedly installed at the lower end of the vehicle body 1, and telescopic rods 16 are fixedly installed on both sides of the filter screen 13. A spring 2 17 is commonly fixedly installed between the inner wall of the telescopic rod 16 and the upper wall of the filter screen 13. The upper end of the telescopic rod 16 is in contact with the filter belt 15. When the filter belt 15 rotates, it contacts the telescopic rod 16 at the lower end, and the filter belt 15 is driven to shake through the spring 2 17 to remove fine sand and dust particles.

[0028] A motor 2 6 is fixedly installed inside the vehicle body 1. A transmission belt 1 61 is commonly connected between the output end of the motor 2 6 and the movable rod 1 11. A transmission belt 2 62 is commonly connected between the movable rod 11 and the movable rod 2 14. Through the arrangement of the transmission belt 1 61 and the transmission belt 2 62, one motor 2 6 can drive the filter belt 15 and the conveyor belt 12 to rotate together.

[0029] In this embodiment, when the device is used to recycle EPDM particles, the sweeping assembly 5 is brought into contact with the ground through the ground block 22, and the motor 1 52 is started. The motor 1 52 drives the sweeping block 54 to rotate through the rotating rod 53, sweeping the EPDM particles on the ground and sweeping the EPDM particles along the side wall of the fixed block 24 into the fixed block 24. The motor 2 6 is started, and the motor 2 6 drives the conveyor belt 12 and the filter belt 15 to operate through the transmission belt 1 61 and the transmission belt 2 62 respectively. At this time, the conveyor belt 12 transports the EPDM particles in the fixed block 24 to the filter belt 15. The filter belt 15 is sent to the filter belt 15. When the filter belt 15 is in operation, it contacts the telescopic rod 16 at the lower end. Under the action of the telescopic rod 16, the filter belt 15 vibrates to remove the sand and gravel particles mixed in the EPDM particles, and then directly discharge them outward through the filter screen 13 at the lower end. Finally, the screened EPDM particles are introduced into the recovery bin 3 through the filter belt 15 for centralized collection. When the EPDM particles are recovered, the device can remove the sand and gravel particles mixed in them and discharge them directly outward, and the screened EPDM particles are centrally recovered through the recovery bin 3.
