Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-3A cement gravel stabilized soil mixer with protective function, comprising a mixer feed hopper 1, a main shaft 2 is rotatably installed between the inner walls of both sides of the mixer feed hopper 1, a mixing device 3 is sleeved on the main shaft 2, a support plate 4 is fixed on the top of the mixer feed hopper 1, and also includes:
[0021] A protective assembly, which is mounted on the top of the mixer feed hopper 1 and is used to prevent dust and gravel from being thrown around when the mixing device 3 rotates;
[0022] The support assembly is installed on the side of the mixer feed hopper 1 and is used to support the protection assembly.
[0023] Two groups of support plates 4 are provided, and the two groups of support plates 4 are respectively installed on the top of the mixer feed hopper 1 and located at the edges of both sides.
[0024] Empty slots 7 are formed on the corresponding sides of the two groups of support plates 4 . Horizontal limit rods 8 are fixedly provided on the sides of the support plates 4 corresponding to the empty slots 7 . The two groups of limit rods 8 slide synchronously in the two groups of slide slots 11 .
[0025] The protection assembly includes a protection plate 9, a movable rod 10 and a slide groove 11. The protection plate 9 is slidably connected between the two groups of support plates 4. Slide grooves 11 are provided at both ends of the protection plate 9. The two ends of the protection plate 9 are respectively fixed with movable rods 10 corresponding to the sides of the two groups of slide grooves 11. The two groups of movable rods 10 are respectively slidably engaged in the two groups of empty grooves 7. The two groups of limit rods 8 are respectively slidably engaged in the two groups of slide grooves 11. First, the mixing device 3 is driven to rotate by the main shaft 2. When it is necessary to protect the mixing device 3 during rotation, the protection plate 9 is pushed so that the protection plate 9 drives the two groups of movable rods 10 to slide in the empty grooves 7 of the two groups of support plates 4 respectively.
[0026] The protective component also includes notches 12. Notches 12 are provided at the corresponding two end positions of the top of the protective plate 9. The notches 12 and the slide grooves 11 are interconnected. When the two groups of notches 12 on the protective plate 9 slide to the position of the two groups of limit rods 8, the two groups of limit rods 8 slide out of the two groups of notches 12 through the two groups of slide grooves 11 respectively, and the protective plate 9 drives the two groups of movable rods 10 to rotate in the empty groove 7, and one side of the protective plate 9 tilts downward.
[0027] The supporting assembly includes an extension rod 5 and a vertical rod 6. The extension rods 5 are fixedly connected to the corresponding two side positions of the front of the mixer feed hopper 1. The vertical rods 6 are fixedly connected to the corresponding sides of the two groups of extension rods 5 near the end positions. The bottom end of the protective plate 9 is in contact with the side of the vertical rod 6. When the bottom of the protective plate 9 is tilted to start to fit with the side of the two groups of vertical rods 6, the protective operation is completed.
[0028] Working principle: First, the mixing device 3 is driven to rotate by the main shaft 2. When the mixing device 3 needs to be protected during the rotation process, the protective plate 9 is pushed so that the protective plate 9 drives the two groups of movable rods 10 to slide in the empty grooves 7 on the two groups of support plates 4 respectively, and the two groups of limit rods 8 synchronously slide in the two groups of slide grooves 11. When the two groups of notches 12 on the protective plate 9 slide to the position of the two groups of limit rods 8, the two groups of limit rods 8 slide out of the two groups of notches 12 through the two groups of slide grooves 11 respectively. At this time, the protective plate 9 drives the two groups of movable rods 10 to rotate in the empty groove 7, and one side of the protective plate 9 tilts downward. When the bottom of the protective plate 9 tilts to begin to fit with the side edges of the two groups of vertical rods 6, the protection operation is completed.
