Traditionally, the proportioning device of concrete blocks is usually directly connected to the mixing production equipment through a pipeline, resulting in the direct and disorderly injection of materials into the production equipment. This direct injection method often causes the materials to accumulate in layers inside the equipment, which not only affects the uniformity of the raw materials, but also significantly reduces the efficiency of subsequent mixing and stirring, thereby increasing the mixing time and affecting the overall production efficiency and product quality.

[0003] Therefore, it is very necessary to invent a concrete proportioning device for concrete blocks. Utility Model Content

The conveying screw is rotatably mounted inside the conveying casing, and either end of the conveying screw rotates through the conveying casing and is fixed to the output end of the servo motor fixedly mounted outside the conveying casing; the conveying casing is connected to the premixing drop box through the injection cover; the feed pipe opening installed on the conveying casing is connected to the storage box through the solenoid valve;

[0006] The premixing drop box comprises a premixing box, a material injection nozzle, a slide, a rotating shaft, a conveying plate and a driving motor.

Either end of the rotating shaft rotates through the premixing box and is fixedly connected to the output end of the driving motor fixedly installed outside the premixing box; a plurality of conveying plates are fixedly installed on the rotating shaft.

[0007] Preferably, the conveyor housing is a "U"-shaped structure, the conveyor housing is located below the material storage box, and the conveying screw is located below the inside of the conveyor housing.

[0008] Preferably, the conveying screw is composed of a screw shaft and a screw blade, the screw blade is fixedly mounted on the screw shaft, and the screw shaft is rotatably mounted on the conveyor housing.

[0009] Preferably, the premixing box is composed of a casing and a conical cover, which are installed together, and the conical cover is connected to the concrete block mixing production equipment.

[0010] Preferably, the two slides fixedly installed inside the premixing box are of a trapezoidal structure, wherein one of the slides is located above and to one side of the other slide, a material sliding channel is formed between the two slides, and one of the slides is located below the injection nozzle.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the production process of concrete blocks, the utility model abandons the traditional practice of directly and disorderly injecting materials into the interior of the production equipment, and instead cleverly introduces the innovative design of a premixing conveying mechanism and a premixing drop box.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides a concrete proportioning device for concrete blocks, comprising a premixing conveying mechanism 1, a material storage box 2 and a premixing drop box 3, wherein the premixing conveying mechanism 1 is connected to a plurality of the material storage boxes 2; the premixing conveying mechanism 1 is connected to the premixing drop box 3, and the premixing drop box 3 is located on one side of the premixing conveying mechanism 1.

[0022] The premixing conveying mechanism 1 includes a conveying housing 11, a conveying screw 12, a servo motor 13, an injection cover 14, a feed nozzle 15 and a solenoid valve 16. The conveying screw 12 is rotatably installed inside the conveying housing 11. Either end of the conveying screw 12 rotates through the conveying housing 11 and is fixed to the output end of the servo motor 13 fixedly installed outside the conveying housing 11; the conveying housing 11 is connected to the premixing drop box 3 through the injection cover 14; the feed nozzle 15 installed on the conveying housing 11 is connected to the storage box 2 through the solenoid valve 16. The premixing conveying mechanism 1 uses its efficient spiral mechanism to orderly convey and preliminarily mix various materials, thereby simplifying the premixing process.

[0023] The premixing drop box 3 includes a premixing box 31, a material injection nozzle 32, a slide 33, a rotating shaft 34, a conveying plate 35 and a driving motor 36. The material injection nozzle 32 installed on the premixing box 31 is connected to the injection cover 14; two sliding tables 33 are installed inside the premixing box 31, and the rotating shaft 34 is rotatably installed inside the premixing box 31. Either end of the rotating shaft 34 rotates through the premixing box 31 and is fixedly connected to the output end of the driving motor 36 fixedly installed outside the premixing box 31; and a plurality of conveying plates 35 are fixedly installed on the rotating shaft 34. The premixing drop box 3 performs a second upward throwing mixing on the premixed materials entering the premixing box 3. This unique mixing method further enhances the premixing effect.

[0024] Embodiment 1:

[0025] Specifically, the conveyor housing 11 is a "U"-shaped structure, the conveyor housing 11 is located below the storage box 2, and the conveying screw 12 is located below the inside of the conveyor housing 11, which is not only conducive to the smooth entry of materials, but also ensures the stability and continuity of materials during the conveying process.

[0026] Specifically, the conveying screw 12 is composed of a screw shaft and a screw blade, the screw blade is fixedly mounted on the screw shaft, and the screw shaft is rotatably mounted on the conveyor housing 11. When the screw shaft rotates, the screw blade pushes the material from one end to the other end, and the material is mixed during the pushing process. This design allows the material to be preliminarily mixed before entering the mixing production equipment, thereby improving the efficiency of subsequent mixing and stirring.

[0027] Further, conveying premixing: the raw materials inside the storage box 2 gradually enter the conveyor housing 11. At this time, the conveying screw 12 pushes the material from one end to the injection cover 14 and injects it into the premixing drop box 3. In this process, the various raw materials are preliminarily premixed.

[0028] Furthermore, the raw materials are conveyed after premixing: the raw materials inside the storage box 2 gradually enter the conveyor housing 11, and the conveying screw 12 rotates in the opposite direction to push the raw materials in the opposite direction of the injection cover 14 until they are gradually pushed and mixed at the end away from the injection cover 14. After the premixing is completed, the conveying screw 12 injects its raw materials into the premixing drop box 3.

[0029] Embodiment 2:

[0030] Specifically, the premixing box 31 is composed of a housing and a conical cover, which are installed together to form a complete mixing space. The housing, as the main part of the premixing box 31, provides a basic place for material mixing. Its internal structure is reasonably designed to accommodate sufficient materials and ensure the fluidity of the materials during the mixing process.

[0031] The conical cover is installed under the casing and connected to the concrete block mixing production equipment, so that the pre-mixed materials can smoothly and quickly enter the subsequent mixing production equipment, thus ensuring the continuity and efficiency of the entire production process.

[0032] The shape of the conical cover is cleverly designed, and its conical structure is conducive to the concentration and guidance of materials, so that the materials can be more evenly distributed inside the premixing box 31. At the same time, the connection port between the conical cover and the concrete block mixing production equipment is reasonably designed to ensure the stability and continuity of the materials during the transmission process.

[0033] Embodiment three:

[0034] Specifically, the two slides 33 fixedly installed inside the premixing box 31 are of a trapezoidal structure, wherein one of the slides 33 is located above one side of the other slide 33 , and the layout is ingenious to form a material sliding channel.

[0035] Furthermore, one of the slides 33 is located below the injection nozzle 32. When the materials enter the premixing box 31 through the injection nozzle 32, they will first fall on the slide. Due to the trapezoidal structure of the slide 33, the materials will slide down along the slope and be blocked and guided by the upper slide 33 during the sliding process, thereby achieving preliminary material mixing.

[0036] Further, below the material sliding channel, a rotating shaft 34 is installed, and a plurality of conveying plates 35 are fixed on the rotating shaft. These conveying plates 35 move with the rotation of the rotating shaft 34, and they throw up and mix the materials that slide down again, further improving the uniformity of material mixing.

[0037] Furthermore, the material sliding channel is tangent to the rotating shaft 34. This design allows the material to smoothly contact the conveying plate 35 during the sliding process and be thrown up for remixing. This tangent relationship ensures the fluidity and uniformity of the material during the mixing process and avoids the accumulation of materials in the sliding channel or the formation of dead corners.

[0038] Embodiment 4:

[0039] First, the raw materials in the storage box 2, such as fly ash, lime, cement, etc., enter the conveying housing 11 of the premixing conveying mechanism 1 through the feed nozzle 15. The opening and closing of the feed nozzle 15 is precisely controlled by the solenoid valve 16 to achieve accurate metering and conveying of the materials.

[0040] Inside the conveyor housing 11, a conveying screw 12 consisting of a screw shaft and a screw blade rotates under the drive of a servo motor 13. The screw blade pushes the material from one end of the conveyor housing 11 to the other end, and achieves preliminary mixing of the material during the pushing process. This spiral conveying and mixing method ensures that the material has been preliminarily and evenly mixed before entering the pre-mixing drop box 3.

[0041] The preliminarily mixed material then enters the injection nozzle 32 of the pre-mixing drop box 3 through the injection cover 14. The pre-mixing box 31 of the pre-mixing drop box 3 is composed of a housing and a conical cover to form a mixing space. The material first falls on two slides 33 of a trapezoidal structure installed inside the pre-mixing box 31 to form a material sliding channel. The material slides down along the inclined surface of the slide 33 and is blocked and guided by the upper slide 33 during the sliding process, thereby achieving preliminary material mixing and guiding.

[0042] In the area below the material sliding channel, a rotating shaft 34 is installed, on which a plurality of conveying plates 35 are fixed. Driven by a driving motor 36, the rotating shaft 34 rotates, and the conveying plates 35 rotate accordingly. The rotating conveying plates 35 throw the materials upward again and mix them, further improving the uniformity of the mixing.

[0043] Finally, the materials fully mixed by the pre-mixing drop box 3 smoothly enter the concrete block mixing production equipment through the conical cover for subsequent mixing and production. The entire device ensures the uniform mixing of concrete block raw materials through precise material metering, efficient conveying and mixing systems, and improves production efficiency and product quality.

[0044] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
