[0002] The cement production process mainly includes steps such as raw meal preparation, clinker calcination, and cement production (grinding). As the first step in cement production, raw meal preparation is of great significance in optimizing the mixing and batching of raw materials, ensuring the accurate composition ratio of raw materials, and improving the stability and quality of raw meal.

[0003] The preparation of cement raw meal mainly involves crushing calcareous raw materials, clayey raw materials, and a small amount of iron ore powder, and then mixing them in a certain proportion to formulate raw meal with suitable composition.

[0031] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] like Figures 1-6 As shown, this utility model specifically relates to a cement raw material mixing mechanism, including a base 100 and an outer shell 200 fixed on the base 100. The outer shell 200 is provided with a mixing assembly 400, which includes a mixing shaft 430 rotatably disposed on the outer shell 200 and a mixing paddle 440 disposed on the mixing shaft 430. A DC motor 410 for driving the mixing paddle 440 to rotate is also provided on the outside of the outer shell 200.

[0035] The stirring paddle 440 is provided in three sets and is equidistantly arranged along the length direction of the stirring shaft 430, and the stirring paddle 440 is provided with multiple blades;

[0036] The outer casing 200 is also provided with a feeding mechanism 500. The feeding mechanism 500 includes a baffle 540 movably connected to the bottom of the outer casing 200 via a column 541. The bottom of the outer casing 200 is provided with a feeding port 220. The baffle 540 opens or closes relative to the feeding port 220 so as to discharge the raw material inside the outer casing 200.

[0037] It should be noted that the outer shell 200 is fixed on the base 100. When the material enters the outer shell 200, the DC motor 410 drives the stirring paddle 440 to rotate through the stirring shaft 430 so as to fully mix the material.

[0038] By equidistantly arranging three sets of agitators 440 on the agitator shaft 430, various materials can be thoroughly mixed. After the mixing is completed, the baffle 540 at the bottom of the outer shell 200 is opened, and the mixed material is discharged through the discharge port 220.

[0039] The stirring assembly 400 is provided in three sets. The three sets of stirring assemblies 400 have the same structure and are arranged along the length of the outer shell 200 so as to fully mix the materials inside the outer shell 200.

[0040] In addition, the use of three sets of mixing components 400, three mixing paddles 440 and multiple mixing blades ensures the uniformity of material mixing.

[0041] The DC motor 410 is fixed to the outside of the housing 200 by the support frame 210, and the output end of the DC motor 410 is connected to the stirring shaft 430 by the coupling 420, which ensures that the transmission process of the DC motor 410 is more stable and avoids the motor shaft from being damaged by force.

[0042] The upper end of the outer shell 200 is provided with an opening, and a top cover 300 for feeding is provided at the opening. The top cover 300 has an inverted trapezoidal shape to better accept the mixed materials.

[0043] The feeding mechanism 500 also includes a stepper motor 510 and a linkage assembly. One end of the linkage assembly is movably connected to the output end of the stepper motor 510, and the other end of the linkage assembly is movably connected to the baffle 540.

[0044] The linkage assembly includes a short link 520 and a long link 530, which are connected to each other. One end of the short link 520 is movably connected to the output end of the stepper motor 510, and one end of the long link 530 is movably connected to one side of the baffle 540.

[0045] Since both the short connecting rod 520 and the long connecting rod 530 are movable, when the stepper motor 510 starts, the short connecting rod 520 and the long connecting rod 530 rotate relative to each other, thereby driving the baffle 540 to open or close relative to the feed port 220.

[0046] In addition, the stepper motor 510 can achieve forward and reverse rotation. When the stepper motor 510 rotates forward, the baffle 540 is closed relative to the discharge port 220, and the bottom of the outer casing 200 is in a sealed state. When the baffle 540 is open relative to the discharge port 220, the mixed material is discharged through the discharge port 220.

[0047] It also includes a material clearing and unblocking mechanism 600 disposed within the outer casing 200. The material clearing and unblocking mechanism 600 includes a transmission support 610 and a conveyor belt 620 disposed on the transmission support 610. The conveyor belt 620 rotates relative to the transmission support 610 to discharge the material accumulated on the conveyor belt 620 through the discharge port 220.

[0048] It should be noted that when various materials enter the outer casing 200, they fall onto the conveyor belt 620, where multiple mixing components 400 simultaneously agitate the materials. After agitation, the materials are discharged through the discharge port 220. During the discharge process, some material may accumulate on the conveyor belt 620. In this case, the conveyor belt 620 is activated to move the accumulated material to the discharge port for further discharge, preventing material accumulation within the outer casing 200.

[0049] In addition, the length of the conveyor belt 620 is less than the length of the outer casing 200, and the conveyor belt 620 is located on one side of the discharge port 220, which makes it easy to discharge the material on the conveyor belt 620 directly through the discharge port 220 and avoid accumulation inside the outer casing 200.

[0050] The outer side of the outer casing 200 is also equipped with a drive motor 630 for driving the conveyor belt 620 to rotate.

[0051] The transmission support 610 includes an inclined plate 611 fixed to the inner wall of the outer shell 200 and a fixed support 612 connected to the conveyor belt 620. The fixed support 612 has grooves 6121 on both sides, and the conveyor belt 620 is disposed in the grooves 6121 through a rotating shaft.

[0052] The inclined plate 611 can fit completely against the inner wall of the outer casing 200 to prevent material from being stuck to the inner wall of the outer casing 200. Similarly, the inclined plate 611 is designed so that all the accumulated material falls onto the conveyor belt 620 so that the accumulated material can be discharged by the conveyor belt 620.

[0053] The inclined plate 611 and the fixed bracket 612 are integrally formed structures.

[0054] The above embodiments are merely specific implementations of this utility model, used to illustrate the technical solutions of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features within the technical scope disclosed in this utility model. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be covered within the protection scope of this utility model.
