Technical Field

[0001] The utility model relates to the technical field of dry mortar conveying, in particular to a dry mortar spiral conveying device. Background Art

[0002] Dry-mix mortar refers to a granular or powdery material made by physically mixing dried and sieved aggregates, inorganic cementitious materials and additives in a certain proportion. In the construction industry, it plays the role of bonding, cushioning, protection and decoration in a thin layer. It is widely used in construction and decoration projects. Screw conveyor is a commonly used conveying device for dry-mix mortar.

The screening frame is provided with through grooves on both side walls perpendicular to the railings, and the distance between the upper and lower groove walls of the through grooves is greater than the diameter of the railings. A connecting shaft is fixed between the railings, and the connecting shaft is placed vertically to the railings; although the above-mentioned conveying device uses the arrangement of the railings, the screening frame, and the connecting shaft to block, screen and separate the rope-like objects such as ropes mixed in the dry mortar before passing through the screening frame into the feeding funnel. However, due to the closed nature of the screw conveyor body, it is impossible to directly observe the internal situation of the device during maintenance, and it is difficult to find potential fault points and problems. It takes more time and manpower to disassemble, inspect and repair, which increases the difficulty of maintenance work. In addition, the dry mortar may produce certain residues and accumulations during the transportation process, or the dry mortar may be blocked or leaked during the transportation process. At this time, it is necessary to disassemble the device and inspect, clean and repair the spiral blades, conveying pipes and other components to ensure that they are restored to normal working condition. However, due to the limitations of the closed structure of the conveyor body, the cleaning work has certain complexity and difficulty, and it is not convenient to use. Therefore, the utility model provides a dry mortar screw conveying device to solve the problems raised in the above background technology. Utility Model Content

The bottom of the screw 5 is in contact with the top of the flap 2. After the handle 6 is turned to drive the screw 5 to rotate so that the screw 5 is separated from the flap 2, the movable plate 4 is rotated to move to one side of the flap 2. The hinged flap 2 is flexible to open and close. The flap 2 is opened in the opening structure of the conveyor body 1. Under the action, the interior of the conveyor body 1 can be maintained or cleaned to ensure that it returns to normal working condition, so that by timely disassembling for maintenance and cleaning, the normal operation of the conveying device can be ensured and its service life can be extended, which is beneficial to improving production efficiency and reducing maintenance costs; a frame 7 is fixedly connected to the top of the feed pipe 3, and a feed port 8 is opened at the bottom of the frame 7. A filter plate 11 is provided inside the frame 7 and above the feed port 8. The dry mortar material is filtered by the filter plate 11 and then transported to the inside of the feed pipe 3 through the feed port 8. Impurities and oversized particles in the dry mortar material are filtered before conveying. The conveyor body 1 can push the material forward more smoothly, which can avoid blockage or damage of the conveying device due to debris or large particles, and extend the service life of the conveying device.

[0026] An observation window 12 is embedded inside each of the multiple flaps 2. The transparent observation window 12 allows direct observation of the internal conditions of the conveyor body 1, so that maintenance personnel can open the corresponding flap 2 to clean the inside of the conveyor body 1, thereby avoiding the tedious problem of opening each flap 2 for inspection and making it more convenient to use.

[0027] A mounting plate 9 is provided inside the frame 7, and a filter plate 11 is embedded inside the mounting plate 9. The mounting plate 9 is slidably connected to the inside of the frame 7. The diameter of the drop port 8 is slightly smaller than the diameter of the feed pipe 3. After being filtered by the filter plate 11, the dry mortar material can smoothly pass through the drop port 8 and fall into the feed pipe 3. The mounting plate 9 movably connected to the inside of the frame 7 is easy to disassemble, thereby facilitating the removal of the mounting plate 9 to clean up the debris on the filter plate 11.

[0028] Two handles 10 are symmetrically fixedly connected to the top of the mounting plate 9 . The mounting plate 9 can be easily operated by operating the handles 10 , so as to facilitate the taking and placing of the mounting plate 9 inside the frame 7 .

[0029] Working principle: after rotating the handle 6 to drive the screw rod 5 to rotate so that the screw rod 5 is separated from the flap 2, the movable plate 4 is rotated to move to one side of the flap 2, and the hinged flap 2 is flexible to open and close. After opening the flap 2, the inside of the conveyor body 1 can be maintained or cleaned under the action of the opening structure of the conveyor body 1 to ensure that it returns to normal working state. Thus, by timely disassembling for maintenance and cleaning, the normal operation of the conveying device can be ensured and its service life can be extended, which is conducive to improving production efficiency and reducing maintenance costs;

[0030] The dry mortar material is filtered by the filter plate 11 and then transported to the inside of the feed pipe 3 through the drop port 8. The impurities and oversized particles in the dry mortar material are filtered before being transported. The conveyor body 1 can push the material forward more smoothly, avoiding blockage or damage of the conveying device due to debris or large particles, thereby extending the service life of the conveying device.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
