Technical Field
[0001] This utility model relates to the field of finished dry-mixed mortar transportation technology, specifically to a finished dry-mixed mortar transportation device. Background Technology
[0002] Dry-mixed mortar is a granular or powdery material physically mixed in a certain proportion from dried and screened aggregates, inorganic cementitious materials, and additives. In the construction industry, it is widely used in thin layers for bonding, padding, protection, and decoration. Due to its complex composition and varying particle sizes and densities, it is necessary to avoid problems such as stratification and segregation during transportation to ensure its quality and performance.
[0003] For example, application number CN202122873154.X, a finished dry mortar conveyor, includes a base plate and a first support located on top of the base plate.

The tops of the first support and the second support are connected together to a feed hopper located above the conveyor belt.
[0004] The aforementioned device cleans the residual mortar on the conveyor belt by rotating cleaning rollers. However, the cementitious materials (such as cement) in the mortar have extremely fine particles, usually 0.001~0.08mm (belonging to the category of "powder"). Cleaning by rotating and scraping can easily cause the powder to be thrown up, making it impossible to collect the thrown-up powder. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0017] The present invention will be further described below with reference to the embodiments.
[0018] Example 1: Reference Figure 1-4This is the first embodiment of the present invention, which discloses a finished dry-mixed mortar transportation device, including: a rectangular mounting plate 1 and support rods 2. Support rods 2 of different lengths are provided on the upper surface of the rectangular mounting plate 1. A rectangular mounting frame 3 is fixedly connected to the vertical surface of the support rods 2. The same cleaning structure 4 is fixedly connected to the vertical surface of a pair of rectangular mounting frames 3. The cleaning structure 4 includes: an arc-shaped blocking frame 5 and an arc-shaped outer frame 6. The arc-shaped blocking frame 5 is fixedly connected to the vertical surface of the rectangular mounting frame 3. The arc-shaped outer frame 6 is connected through the lower surface of the arc-shaped blocking frame 5. A blocking rod 7 is provided on the bottom surface inside the arc-shaped blocking frame 5. A pair of symmetrical rotating rods are rotatably connected to the vertical surface inside the arc-shaped blocking frame 5. A cleaning brush 8 is provided on the rod body of the pair of rotating rods.
[0019] A pair of connecting rods 9 are installed through the vertical surface of the outer side of the arc-shaped blocking frame 5. A rotating rod is fixedly connected to the circular surface of the pair of connecting rods 9. A gear column that is penetrated is fixedly connected to the rod body of the pair of connecting rods 9. The teeth of the pair of gear columns are meshed with the same synchronous belt 10. An L-shaped mounting base 11 is fixedly installed on the vertical surface of the outer side of the arc-shaped blocking frame 5. A drive motor 12 is installed on the upper surface of the L-shaped mounting base 11.
[0020] A rectangular lifting ring is slidably connected to the vertical surface inside the arc-shaped outer frame 6. A fine filter screen 13 is fixedly connected to the inner ring of the rectangular lifting ring. A rectangular block is connected through the lower surface of the fine filter screen 13. A U-shaped handle is fixedly connected to the lower surface of the rectangular block. A lead screw 14 is rotatably connected to the vertical surface outside the arc-shaped outer frame 6. A torsion bar 15 is fixedly connected to the end of the lead screw 14 away from the arc-shaped outer frame 6.
[0021] When the equipment is in use, the conveyor belt is in operation. First, start the drive motor 12. The output end of the drive motor 12 is connected to one of the connecting rods 9, and a gear column is fixedly connected to the body of each pair of connecting rods 9. The teeth of the pair of gear columns are meshed with the same synchronous belt 10. Rotating rods are fixedly connected to the circular surfaces of the pair of connecting rods 9. Cleaning brushes 8 are provided on the body of the pair of rotating rods. When the drive motor 12 starts, the pair of rotating rods will rotate, thereby cleaning the conveyor belt through the cleaning brushes 8. Because a negative pressure fan is connected through the bottom surface of the arc-shaped outer frame 6 (after the fan starts, the fan blades rotate at high speed, forcibly drawing the air in the area where the fan is located (such as one side of the workshop or one end of the farm) to the outside, making the air pressure in this area lower than the outdoor atmospheric pressure, forming a "negative pressure zone"), the dust raised after the fan starts will be adsorbed and guided. When passing through the fine filter screen 13, the dust in the air will be filtered out and collected.
[0022] Example 2: Reference Figure 1 and 5This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a circular ring is installed on the upper vertical surface of each pair of rectangular mounting frames 3; a rotating rod is rotatably connected to the inner ring of the circular ring; a roller is fixedly connected to the body of the rotating rod; both rollers are connected to the same conveyor belt; several limiting structures are provided on the upper surface of the rectangular mounting frames 3; the limiting structures include: a rectangular mounting strip 16; docking plates 17 are fixedly connected to the vertical surfaces on both sides of the rectangular mounting strip 16; a set of symmetrical inclined plates 18 are provided on the upper surface of the rectangular mounting strip 16; a pair of inclined plates 18 are rotatably connected to guide roller shafts 19; a pair of rectangular fixing plates are also provided on the upper surface of the rectangular mounting strip 16; both rectangular fixing plates are connected to the same round rod; a rotating cylinder 20 is fixedly connected to the body of the round rod.
[0023] When the drive motor connected to the pair of rollers is started, the conveyor belt will begin to work. Because the docking plate 17 is fixedly connected to the vertical surfaces on both sides of the rectangular mounting strip 16, a set of symmetrical inclined plates 18 is provided on the upper surface of the rectangular mounting strip 16, and a pair of inclined plates 18 are rotatably connected to the guide roller shaft 19. A pair of rectangular fixing plates are also provided on the upper surface of the rectangular mounting strip 16, and both of the rectangular fixing plates are connected to the same round rod. The rotating cylinder 20 is fixedly connected to the rod. During the rotation of the conveyor belt, due to the limitation of the angle of the pair of guide roller shafts 19 and the weight of the goods themselves, the middle of the conveyor belt will come into contact with the rotating cylinder 20, and the goods will eventually be concentrated at the center of the conveyor belt.
[0024] The remaining structure is the same as that in Example 1.
[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
