[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0020] In common mixing equipment, the observation window is usually flip-up, with the opening facing downwards. When operators want to observe the mixing of materials inside the hopper, they usually need to stick their heads into the observation window to see the mixing situation. However, if the mixing equipment is operated incorrectly at this time, the rotating mixing blades can cause injury to the operator.

[0021] Based on this, an exemplary embodiment of this application provides a mixer with an observation window. An observation window assembly is provided on one side of the hopper in the mixer. The observation window assembly includes an observation window door panel and a cylinder. The observation window door panel rotates around its hinge point with the hopper as the center of rotation, thus opening and closing the observation window door panel. When the observation window door panel rotates downwards around the hinge point, the opening between the observation window assembly and the hopper faces upwards. At this time, the operator can observe the material mixing without inserting their head into the hopper. Simultaneously, the observation window door panel can prevent the operator from inserting their head into the hopper, ensuring the operator's safety. The mixing assembly includes a mixing shaft and a mixing blade assembly mounted on the mixing shaft. The rotation direction of the mixing blade assembly is the same as the opening direction between the observation window assembly and the hopper. When observing the material mixing from one side of the observation window assembly, the mixing blade assembly rotates from bottom to top, allowing the operator to promptly detect the rotating mixing blade assembly while observing the material mixing, preventing injury from the rotating mixing blades.

[0022] An exemplary embodiment of this application provides a mixer with an observation window, such as... Figure 1As shown, the mixer includes a hopper 10 and a mixing assembly 20. The mixing assembly 20 is rotatably disposed inside the hopper 10. An observation window assembly 30 is provided on one side of the hopper 10. The observation window assembly 30 includes an observation window door panel 301 and a cylinder 302. The lower part of the observation window door panel 301 is hinged to the hopper 10. One end of the cylinder 302 is hinged to the observation window door panel 301, and the other end is hinged to the frame supporting the hopper 10, so that the observation window door panel 301 rotates around the hinge point with the hopper 10 as the center of rotation, realizing the opening and closing of the observation window door panel 301. In this way, the opening between the observation window assembly 30 and the hopper 10 faces upward. At this time, the operator can observe the mixing of materials without putting his head into the hopper 10. At the same time, the observation window door panel 301 can prevent the operator from putting his head into the hopper 10, ensuring the safety of the operator. The mixing assembly 20 includes a mixing shaft 201, sealing structures disposed at both ends of the mixing shaft 201, and a mixing blade assembly disposed on the mixing shaft 201; the sealing structures prevent material from the hopper 10 from entering the shaft and the interior of the sealing structures, thus avoiding wear on the shaft; for example Figure 3 As shown, the rotation direction of the stirring blade assembly is the same as the opening direction between the observation window assembly 30 and the hopper 10. When observing the mixing of materials from the side of the observation window assembly 30, the stirring blade assembly rotates from the bottom to the top, so that the operator can promptly detect the rotating stirring blade assembly when observing the mixing of materials, thus avoiding injury to the operator from the rotating stirring blade.

[0023] like Figure 2 and 3 As shown, there are multiple sets of stirring blade assemblies, arranged at intervals around the stirring shaft 201. Each stirring blade assembly includes a stirring arm 202 and a first stirring blade 203. The stirring arm 202 is positioned on the circumferential surface of the stirring shaft 201 in a direction perpendicular to its axis. The first stirring blade 203 is located at the end of the stirring arm 202. For example, there are eight sets of stirring blade assemblies, arranged at equal intervals around the stirring shaft 201, ensuring that the material is thoroughly stirred in all corners of the container, thus improving the stirring quality and efficiency.

[0024] The first stirring blade 203 includes a shovel section 2031 and a distributor section 2032. The shovel section 2031 is fixedly disposed at the end of the stirring arm 202, and the distributor sections 2032 are disposed on both sides of the shovel section 2031. The shovel section 2031 and the distributor sections 2032 enclose a shovel space with a pointed tip. During stirring, the distributor section 2032 can help disperse materials, accelerate material expansion, and reduce resistance during the stirring process. Preferably, the distributor section 2032 has a distributor surface that is concave towards the shovel section 2031, which helps to further reduce resistance during the stirring process. To prevent the first stirring blade 203 from interfering with the agitator's hopper 10, a portion of the first stirring blade 203 is disposed on the stirring arm 202 near the end of the stirring shaft 201. Preferably, half of the first stirring blade 203 is disposed on this portion.

[0025] In one embodiment, the stirring blade assembly further includes a second stirring blade disposed on the outer peripheral surface of the stirring arm 202. The second stirring blade is disposed perpendicular to the outer peripheral surface of the stirring arm 202 and inclined relative to the stirring shaft 201, enabling multi-part stirring and ensuring stirring at multiple angles and directions to improve the mixing effect.
