Description

Technical Field

[0001] This utility model relates to the technical field of concrete mixing devices, specifically a concrete mixing device with an anti-clogging discharge structure. Background Technology

[0002] A search revealed Chinese patent publication number CN219190724U, which discloses a concrete mixing device that is easy to clean. The device includes a closed cylindrical body. A motor base is mounted on the upper end plate of the closed cylindrical body, and a first motor and a second motor are installed inside the motor base. A stirring shaft with stirring blades is installed through the upper end plate of the closed cylindrical body. In use, this technical solution achieves timely scraping and spray cleaning of materials adhering to the walls by adding a scraping and cleaning component inside the closed cylindrical body that does not interfere with the stirring shaft. However, this structure has issues with the spray pipe and internal water supply. The pipes and nozzles are located inside the cylinder, and are easily worn and clogged due to the harsh environment during concrete mixing, which affects the cleaning effect and reduces applicability. At the same time, existing concrete mixing devices lack a discharge anti-clogging structure. High concrete viscosity or uneven particle distribution can easily lead to discharge port blockage, which not only affects work efficiency but may also cause unnecessary damage to the equipment, thus affecting the device's performance and failing to meet usage requirements. Therefore, a concrete mixing device with an anti-clogging discharge structure is proposed to solve the above-mentioned problems. Utility Model Content

A guide plate 511, fitting against the inner wall of the extension frame 56, is fixedly mounted on the top of the dredging rod 59. The guide plate 511 improves the flow rate of the material. Regarding the stability of the unblocking rod 59 during movement, it should be noted that the specific structure and working principle of the electric telescopic rod 32, the first motor 35, the servo motor 43, and the second motor 54 are all based on existing technology. This concrete mixing device with an anti-clogging discharge structure, through the use of the mixing anti-clogging mechanism 5, effectively facilitates the user in unblocking the discharge port of the batching cylinder 2 during concrete mixing, effectively preventing blockage, ensuring smooth discharge, and improving the applicability of the device. The coordinated use of the lifting adjustment mechanism 4 and the mixing anti-clogging mechanism 5 effectively facilitates the user in removing the mixing component from the batching cylinder 2 when cleaning the concrete mixing device is required, effectively facilitating cleaning work and improving user convenience. Simultaneously, the scraper plate 53 effectively scrapes away material adhering to the inner wall of the batching cylinder 2, preventing material accumulation.

[0024] In operation, when concrete needs to be mixed, the concrete raw materials enter the batching cylinder 2 through the feeding hopper 48. At this time, the second motor 54 starts, driving the mixing rod 51 to rotate through the second gear 55. The mixing plate 52 and scraper 53 on the mixing rod 51 begin to work, mixing the concrete raw materials evenly and scraping off the material adhering to the inner wall. When discharging, the electric telescopic rod 32 drives the baffle plate 33 to move away, allowing the mixed concrete to enter the discharge cylinder 34 from the discharge pipe 31, be conveyed by the conveying auger, and discharged from the discharge pipe. If any signs of blockage are found at the discharge port, the operator can adjust the discharge method by rotating the... The rotating disc 58 drives the second screw 57 to rotate, causing the unblocking rod 59 and spiral blade 510 to descend to the discharge port. The rotation of the mixing rod 51 then helps to unblock the concrete mixing device. When cleaning is required, the user can start the servo motor 43, which drives the first screw 42 to rotate via the first gear 44. This causes the threaded plate 45 to move the lifting column 46 and the cylinder cover plate 47 upward, moving the mixing anti-blocking mechanism 5 outside the batching cylinder 2. This provides the user with an unobstructed cleaning space, effectively improving the convenience and efficiency of the cleaning operation.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] In summary, this concrete mixing device with an anti-clogging discharge structure, through the coordinated use of the lifting and adjusting mechanism 4 and the mixing anti-clogging mechanism 5, effectively facilitates the user's cleaning by removing the mixing component from the batching cylinder 2 when cleaning is required, thus improving the ease of cleaning. Simultaneously, the scraper 53 effectively removes material adhering to the inner wall of the batching cylinder 2, preventing material accumulation. Furthermore, the mixing anti-clogging mechanism 5 facilitates the user's unblocking of the discharge port of the batching cylinder 2 during concrete mixing, preventing blockages, ensuring smooth discharge, improving the device's applicability, and facilitating user operation, thereby solving the problems mentioned in the background art.
