Description

Technical Field

[0001] This utility model relates to the field of track repair technology, specifically a rubber track repair device. Background Technology

[0002] With the popularization of national fitness activities and the continuous improvement of school sports facilities, rubber running tracks, as a type of sports field with good elasticity, anti-slip properties, and effective protection for athletes' joints, have been widely used. However, due to long-term use, erosion from the natural environment (such as ultraviolet radiation and rain erosion), and wear and tear on sports equipment, rubber running tracks inevitably suffer from wear, potholes, cracks, and other damage.

[0003] Currently, the repair of rubber running tracks is mainly done manually. However, traditional manual repair methods have several problems. First, in the material mixing stage, due to the lack of precise monitoring and control equipment, it is difficult to accurately mix rubber granules and adhesive in the correct proportions. Improper mixing often occurs, such as too much or too little adhesive. This not only wastes repair materials and increases repair costs but also affects the quality of the repaired track, such as weak adhesion and poor elasticity. Second, when leveling the repair surface, manual operation makes it difficult to ensure the flatness and density of the repair surface. Relying solely on simple tools for leveling cannot ensure the even spreading of the repair material or guarantee its density, thus affecting the performance and lifespan of the repaired track. Utility Model Content

[0004] The purpose of this invention is to provide a rubber track repair device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber track repair device, comprising a box, a feeding cylinder and a leveling plate, wherein a servo motor is installed on one side of the box, the output end of the servo motor extends into the mixing chamber inside the box and is equipped with a stirring blade, and the inner wall of the mixing chamber is uniformly provided with heating plates, and a rubber granule chamber and an adhesive chamber are arranged side by side inside the box above the mixing chamber, and a material level sensor is installed at the top of both the rubber granule chamber and the adhesive chamber;

[0014] 1. Precise ingredient dispensing and mixing to reduce material waste:

[0015] By installing level sensors at the top of the rubber granule and glue hoppers, the material level inside can be monitored in real time, ensuring that materials are dispensed as needed. The combination of the level sensors and the discharge valve allows the device to precisely inject the correct ratio of rubber granules and glue based on the actual size of the crater. This design effectively avoids material waste caused by improper mixing in traditional repair processes, significantly reducing repair costs.

[0016] The mixing chamber is equipped with evenly spaced heating plates on its inner wall, which, together with the servo motor-driven stirring blades, enable rapid and uniform mixing of rubber granules and adhesive, improving mixing efficiency and quality.

[0056] Two electric push rods 30 are mounted side by side on the inner side of the walking frame 9. The output end of each electric push rod 30 extends to the outer side of the walking frame 9 and is connected to a leveling plate 6. The leveling plate 6 is a key component of this utility model, with a scraper 27 at the bottom and a groove 31 at the top.

[0057] A vibration motor 28 is installed in the middle of the trough 31. The main function of the vibration motor 28 is to generate vibration to assist in the operation of the leveling plate 6. Telescopic rods 29 are installed side by side inside the trough 31 on both sides of the vibration motor 28. The output end of the telescopic rod 29 extends to the bottom of the leveling plate 6 and is movably connected to the scraper 27.

[0058] One end of the scraper 27 is movably connected to the bottom of the leveling plate 6 via a rotating shaft. Specifically, the rotating shaft is installed in a pre-set hole at the bottom of the leveling plate 6, and one end of the scraper 27 is movably connected through this rotating shaft. The other end of the scraper 27 is also movably connected to the output end of the telescopic rod 29 via a rotating shaft. This connection method allows the scraper 27 to swing within a certain range, thereby adjusting the angle between it and the leveling plate 6.

[0059] The angle between the scraper 27 and the leveling plate 6 is adjustable. The specific adjustment process is as follows: By controlling the extension and retraction length of the telescopic rod 29, the swing angle of the scraper 27 can be changed. When the telescopic rod 29 extends, one end of the scraper 27 is lifted upward, which increases the angle between the scraper 27 and the leveling plate 6; conversely, when the telescopic rod 29 shortens, one end of the scraper 27 is pressed downward, which decreases the angle between the scraper 27 and the leveling plate 6.

[0060] When this application embodiment is used,

[0061] Preparation: Check the battery level 24 to ensure it is sufficient. If the battery is low, charge it promptly to ensure the device has enough power to operate. Observe the material status in the rubber granule bin 19 and glue bin 22 through the viewing window 2. If the material level sensor 20 indicates insufficient material, replenish the rubber granules and glue in time to ensure the repair work can proceed normally. The operator holds the push handle 14 and pushes the device to the area to be repaired on the rubber track via the universal rollers 8, and positions the device.

[0062] In the batching stage: Based on the actual size of the pits in the rubber track, the required ratio of rubber granules and adhesive is input into the controller 15. The controller 15 controls the opening of discharge valve 17 and discharge valve 25, allowing rubber granules to be released quantitatively into the mixing silo 26 through discharge pipe 18 and adhesive through discharge pipe 23 in a set ratio. The level sensor 20 monitors the material height in the rubber granule silo 19 and adhesive silo 22 in real time and transmits the signal to the controller 15 to control the discharge rate.

[0063] Mixing stage: After the rubber granules and adhesive enter the mixing chamber 26, the servo motor 3 is activated by the controller 15. The servo motor 3 drives the stirring blade 16 to rotate at high speed in the mixing chamber 26, mixing the rubber granules and adhesive. At the same time, the heating plate 21 is activated by the controller 15, and the temperature in the mixing chamber 26 is adjusted according to the preset temperature parameters to maintain a constant temperature, ensuring that the rubber granules and adhesive are fully and uniformly mixed to achieve the ideal mixing effect.

[0064] Feeding Stage: After the mixed repair material is prepared in the mixing hopper 26, the discharge valve 4 on the discharge pipe 12 is opened via the controller 15, allowing the repair material to flow from the mixing hopper 26 into the feeding cylinder 7 via the discharge pipe 12. The discharge motor 10 is then turned on, driving the screw conveyor 32 to rotate within the feeding cylinder 7, uniformly and continuously pushing the mixed repair material to the discharge pipe 5, and precisely applying it to the repair surface of the rubber track through the discharge nozzle 33. The operator can adjust the speed of the discharge motor 10 via the controller 15 to control the feeding speed and discharge volume.

[0065] Leveling stage: While feeding the material, the electric push rod 30 is activated via controller 15. The electric push rod 30 pushes the leveling plate 6 down to a suitable height, allowing the scraper 27 to contact the repair surface. The vibration motor 28 is turned on, generating vibration to assist the leveling plate 6 and scraper 27 in spreading and compacting the repair material. Depending on the specific condition of the repair surface, the extension length of the telescopic rod 29 is controlled via controller 15 to adjust the angle between the scraper 27 and the leveling plate 6, ensuring that the repair material is evenly spread on the repair surface and guaranteeing the flatness and density of the repair surface.

[0066] Repair Completion and Finishing Work: After completing the feeding and leveling work in the repair area, shut down the discharge motor 10, electric push rod 30, vibration motor 28, servo motor 3, and heating plate 21. Close discharge valve 4, unloading valve one 17, and unloading valve two 25 to prevent material leakage. The operator holds the push handle 14 and pushes the device away from the repair area via the universal rollers 8. The device is then cleaned and maintained to prepare it for the next use.
