Description

Technical Field

[0001] The utility model belongs to the technical field of concrete raw material transportation, and specifically refers to a maintenance baffle for a concrete raw material transportation belt. Background Technique

[0002] Concrete, as a building material widely used in the field of civil engineering, is mainly composed of aggregates such as cement, sand, and stone mixed and stirred with water in a certain proportion. Its rich raw materials, low price, and simple production process make concrete play an important role in the modern construction industry. However, during the transportation of concrete raw materials, especially in the feeding link of the belt conveyor, a thorny problem is often faced: that is, the materials are prone to splashing during high-speed transmission, especially when the humidity and particle size of the concrete raw materials are uneven, the splashing phenomenon is more serious. These splashed materials not only pollute the working environment and increase the cleaning difficulty, but more importantly, they will inevitably adhere to the tail end of the belt conveyor and its surrounding components, causing a certain degree of damage to the equipment.

[0003] In addition, for the daily maintenance and repair work of the belt conveyor, the splashed materials and the exposed conveyor belt also pose a certain safety hazard. During the repair process, if the staff accidentally touches the rapidly rotating conveyor belt, it is extremely easy to cause personal injury accidents. Content of the Utility Model

[0024] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the drawings in the specific embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0025] Such as Figures 1-6As shown in the figure, the utility model provides a maintenance baffle for a concrete raw material conveying belt, which includes a support frame. The support frame includes an N-shaped bracket one 10, and the N-shaped bracket one 10 is arranged below the L-shaped bracket one 7. A connecting plate 12 is arranged on one side of the N-shaped bracket one 10, and an N-shaped bracket two 11 is arranged on one side of the connecting plate 12. A maintenance baffle 1 is arranged at the upper end of the support frame. The maintenance baffle 1 includes a shielding cover 9. An L-shaped bracket one 7 is arranged on one side of the shielding cover 9, and an L-shaped bracket two 8 is arranged on the other side of the shielding cover 9. A sleeve 17 is arranged at the lower end of one side of the L-shaped bracket one 7, and a sliding column two 25 is arranged at the lower end of the other side of the L-shaped bracket one 7. A sliding column one 4 is arranged at the lower end of one side of the L-shaped bracket two 8. A lifting component is arranged inside the support frame. The lifting component includes a bearing 15, and the bearing 15 is arranged at the inner bottom end of one side of the N-shaped bracket one 10. A lead screw 16 is arranged on the bearing 15, and the lead screw 16 is sleeved inside the sleeve 17. The lead screw 16 is threadedly connected with the sleeve 17. A bevel gear two 14 is arranged at the lower end of the lead screw 16. A connecting shaft 26 is rotatably arranged on the side wall of the N-shaped bracket one 10. A bevel gear one 13 is arranged at one end of the connecting shaft 26, and a crank 18 is arranged at the other end of the connecting shaft 26. A cylindrical groove one 3 is arranged inside the N-shaped bracket two 11, and the sliding column one 4 is slidably arranged inside the cylindrical groove one 3. A cylindrical groove two 24 is arranged inside the other side of the N-shaped bracket one 10, and the sliding column two 25 is slidably arranged inside the cylindrical groove two 24.
