[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a dust removal and sealing device for a dry mortar mixer, comprising a frame and also comprising: a mixing assembly for preventing mortar from overflowing during mixing; the mixing assembly comprises a slide, a powder barrel and a sealing plate, the slide is slidably connected to the frame, a plurality of powder barrels are rotatably connected to the slide, a plurality of sealing plates are fixedly connected to the slide, and the sealing plates are used to seal the flared openings on both sides of the powder barrel.

[0005] Beneficial effects

[0006] The utility model provides a dust removal and sealing device for a dry mortar mixer, which has the following beneficial effects compared with the prior art:

[0007] When the mortar needs to be mixed, the relevant technicians start the motor, so that the transmission gear drives the screw fixedly connected to it to start rotating, so that the slide cylinder threaded on the screw starts to slide along the connection between it and the frame, so that the slide cylinder drives the powder barrel filled with dry powder to immerse in the water. When the powder barrel is completely immersed in the water, the gear contacts the rack synchronously, so that the gear starts to drive the guide rod to rotate under the cooperation of the rack meshed with it, so that the worm fixedly connected to the guide rod rotates synchronously, and the worm drives the worm wheel meshed with it to rotate synchronously, so that the worm wheel drives the wheel shaft fixedly connected to it to start rotating, so that the wheel shaft drives the wheel shaft fixed to it to start rotating. The connected gear B starts to rotate, thereby causing gear B to drive multiple gears A meshing with it to rotate synchronously, thereby causing gear A to drive the powder barrel fixedly connected to it to start rotating, so that the flared opening on the powder barrel is out of the blocking range of the powder barrel, so that the water in the frame starts to enter the powder barrel to flush out the dry powder, and the dry powder in the powder barrel starts to mix with the water in the frame; at the same time, when the screw rotates, the connecting rod starts to rotate synchronously with the screw in cooperation with the belt connected to it, thereby causing the connecting rod to drive the fan disk fixed on it to rotate synchronously. During the descent of the slide barrel, the fan disk can accelerate the flow of water by stirring, thereby accelerating the full mixing of water and dry powder. BRIEF DESCRIPTION OF THE DRAWINGS

Multiple powder barrels 202 are rotatably connected to the slide 201. Multiple sealing plates 203 are fixedly connected to the slide 201. The sealing plates 203 are used to seal the flared openings on both sides of the powder barrel 202.

[0018] For the above examples, those skilled in the art should know that when implementing the above technical solutions, they are not limited to the specific rack 101 described in the above embodiments. For example, a conduit may be provided at the bottom of the rack 101. The purpose of such a provision is to facilitate the drainage of water into the rack 101 in this way.

[0019] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific sealing plate 203 described in the above embodiments. For example, a sealing rubber gasket is provided on the inner arc circle of the sealing plate 203. The purpose of this setting is to facilitate increasing the sealing effect of the connection in this way, thereby preventing water from entering the powder cartridge 202 when it is completely immersed in water.

[0020] Specifically, the powder cylinders 202 are fixedly connected with gears A204 , which are meshed with gears B205 , and the axis of the gears B205 is fixedly connected with an axle 206 , which is rotatably connected with the slide 201 .

[0021] For the above examples, those skilled in the art should know that when implementing the above technical solutions, they are not limited to the specific axle 206 described in the above embodiments. For example, a bearing ring is provided at the connection between the axle 206 and the frame 101.

[0030] For the above example, those skilled in the art should know that when implementing the above technical solution, they are not limited to the specific motor 308 described in the above embodiment. For example, the motor 308 should be a motor with multiple adjustable speeds. The purpose of this setting is to facilitate the adjustment of the speed of the powder cartridge 202 being immersed in water in this way.

[0031] In the embodiment of the present invention, when it is necessary to mix mortar, the relevant technicians start the motor 308, so that the transmission gear 307 drives the screw rod 303 fixedly connected thereto to start rotating, so that the slide 201 threadedly connected to the screw rod 303 starts to slide along the connection between it and the frame 101, so that the slide 201 drives the powder barrel 202 filled with dry powder to be immersed in the water. When the powder barrel 202 is completely immersed in the water, the gear 301 contacts the rack 302 synchronously, so that the gear 301 starts to drive the guide rod 209 to rotate in cooperation with the rack 302 meshed with it, so that the worm 208 fixedly connected to the guide rod 209 rotates synchronously, so that the worm 208 drives the worm wheel 207 meshed with it to rotate synchronously, so that the worm wheel 207 drives the wheel shaft 206 fixedly connected thereto to start rotating, so that the wheel shaft 206 06 drives the gear B205 fixedly connected to it to start rotating, thereby causing the gear B205 to drive multiple gears A204 meshing with it to rotate synchronously, thereby causing the gear A204 to drive the powder barrel 202 fixedly connected to it to start rotating, so that the flared opening on the powder barrel 202 is out of the blocking range of the powder barrel 202, so that the water in the frame 101 starts to enter the powder barrel 202 to flush out the dry powder, and the dry powder in the powder barrel 202 starts to mix with the water in the frame 101; at the same time, when the screw rod 303 rotates, the connecting rod 305 starts to rotate synchronously with the screw rod 303 under the cooperation of the belt 304 connected to it for transmission, so that the connecting rod 305 drives the fan disk 306 fixedly connected thereto to rotate synchronously. During the descending process of the slide 201, the fan disk 306 can accelerate the flow of water by stirring, thereby accelerating the full mixing of water and dry powder.

[0032] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0033] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. It can be categorized into two types: detachable connection and non-detachable connection.

[0034] (1) Removable connection: Components are fastened together using screws, splines, wedge pins, etc. This type of connection allows for disassembly during maintenance without damaging the components. However, the connectors used must be of the correct specifications (e.g., length of bolts, keys, wedge pins) and properly tightened.

[0035] (2) Non-detachable connections: These mainly refer to welding, riveting, and tenoning. Since parts must be forged, sawed, or oxygen-cut for disassembly during repair or replacement, they are generally not reusable. Furthermore, attention should be paid to workmanship quality, technical inspection, and remedial measures (such as calibration and polishing) during connection.

[0036] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinged connection referred to in this application means that the component can rotate along an axial constraint.

[0037] In some cases, the sliding connections and hinges referred to in this application may also be damped so that the components have the ability to maintain a desired position.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
