Description

Technical Field

[0002] Dry-mix mortar refers to a granular or powdery material that is physically mixed in a certain proportion with dried and sieved aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers). It is transported to the construction site in bags or bulk and can be used directly after adding water and mixing. It is also called mortar dry powder, dry mix, and dry mixing powder. Some construction adhesives also belong to this category. Dry-mix mortar is used in the construction industry in thin layers to perform bonding, cushioning, protection and decoration functions, and is widely used in construction and decoration projects.

[0003] When inorganic cementitious materials (such as cement) are left for a long time, they will clump. If aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) are directly mixed, the lumped cement may be difficult to crush during the mixing process, which may cause uneven physical mixing and affect the quality of dry-mix mortar. Therefore, a dry-mix mortar mixer is proposed to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0021] In the embodiment, Figure 1-3 A dry mortar mixer is provided, comprising a mixer body 1, a driving motor 2 is fixedly connected to the right end of the mixer body 1, a rotating shaft 3 having one end penetrating through and extending to the left end of the mixer body 1 is fixedly connected to the output end of the driving motor 2, a spiral stirring blade 4 is fixedly connected to the outer side of the rotating shaft 3, a cover plate 5 is hingedly connected to the top of the mixer body 1, two handles 6 are fixedly connected to the top of the cover plate 5, a first feeding assembly 7 is arranged at the top of the cover plate 5, a second feeding assembly 8 is arranged at the top of the mixer body 1, and a discharging assembly 9 is arranged at the left end of the mixer body 1;

[0022] The second feeding assembly 8 includes a crushing bucket 81, the top of the mixer body 1 is fixedly connected with the crushing bucket 81, the bottom end of the crushing bucket 81 is connected to the inner cavity of the mixer body 1, the inner side of the crushing bucket 81 is rotatably connected with two crushing shafts 82, the outer sides of the two crushing shafts 82 are fixedly connected with gears 83, the two gears 83 are meshed with each other, the outer side of the rear crushing shaft 82 is fixedly connected with a sprocket chain transmission mechanism 84, the sprocket chain transmission mechanism 84 is fixedly connected to the outer side of the rotating shaft 3, the top of the crushing bucket 81 is fixedly connected with a second feeding hopper 85, the top of the second feeding hopper 85 is hinged with a second feeding cover plate 86, the second feeding cover plate 86 is fixedly connected with a second handle 87, and the outer sides of the two crushing shafts 82 are fixedly connected with crushing rollers 88.

[0023] Through the above arrangement, the first feeding assembly 7 is opened, and the quartz sand and polymer are put in from the first feeding assembly 7. The second handle 87 is held to rotate the second feeding cover plate 86 along the hinged position to open it, and cement is put into the second feeding hopper 85. The cement falls into the crushing bucket 81, and the driving motor 2 is started. The driving motor 2 drives the rotating shaft 3 to rotate. Under the transmission action of the sprocket chain transmission mechanism 84, the power is transmitted to the crushing shaft 82 at the rear side. Since the two gears 83 are meshed with each other, the two crushing shafts 82 will rotate, and the two crushing rollers 88 will rotate accordingly, and the cement will fall out. It falls onto the two crushing rollers 88, and the agglomerated cement will be crushed by the two crushing rollers 88, while the unclumped cement will normally fall from the gap between the crushing rollers 88 and the gap between the two crushing rollers 88 and the crushing bucket 81, and finally fall into the mixer body 1. Since the rotating shaft 3 can drive the spiral stirring blade 4 to rotate, the quartz sand, polymer and cement are stirred and mixed into a dry powder mortar, which can be discharged from the discharging component 9 after the mixing is completed (since the spiral stirring blade 4 is spiral, it can push the material to move to the left. If the discharging component 9 is opened, the material can be discharged from the discharging component 9).
