[0026] Please see Figure 1-5This utility model provides a technical solution: a horizontal mixer, the mixer body 1 includes a stirring shaft 11, the stirring shaft 11 is used to stir the materials during the mixing process to achieve uniform mixing of the materials. The mixer body 1 and the stirring shaft 11 inside it are existing equipment in the art, so they will not be described in detail here. The top of the mixer body 1 is an open structure. A support shell 2 is fixedly installed on the top of the mixer body 1. A protective shell 3 is fixedly installed on the support shell 2 and the left side of the mixer body 1. A uniform spraying structure is installed inside the support shell 2 and the protective shell 3. The uniform spraying structure includes a movable spraying unit 4 and a linkage unit 5. The movable spraying unit 4 is installed inside the support shell 2, and the support shell 2 is used to provide support and protection for the movable spraying unit 4. The linkage unit 5 is installed inside the protective shell 3, and the protective shell 3 is used to support and protect the linkage unit 5. The movable spraying unit 4 and the stirring shaft 11 are connected through the linkage unit 5. Through the connection of the linkage unit 5, the movable spraying unit 4 can share the same power source with the stirring shaft 11 and achieve synchronous operation.

[0027] Specifically, the mobile spray unit 4 includes a reciprocating screw 41, a limiting guide rod 42, a slider 43, a water guide pipe 44, a spray head 45, a fixed water pipe 46, and a water supply pipe 47. The two ends of the reciprocating screw 41 are rotatably connected to the left and right sides of the support shell 2, respectively. The reciprocating screw is a type of screw that enables the slider 43 to reciprocate without changing the direction of rotation of the main shaft. It is an existing device, and its specific structure will not be described in detail. The two ends of the limiting guide rod 42 are fixedly installed on the left and right sides inside the support shell 2, and the limiting guide rod 42... The guide rod 42 is located below the reciprocating screw 41. The guide rod 42 limits the movement trajectory of the slider 43, ensuring that the slider 43 does not deviate laterally during linear reciprocating motion. The slider 43 has a helical cam inside that engages with the helical groove of the reciprocating screw 41. The slider 43 is movably connected to the reciprocating screw 41 and also slidably connected to the guide rod 42. Through the engagement of the helical cam and the helical groove, the slider 43 and the reciprocating screw 41 are movably connected. Furthermore, because the guide rod 42... The slider 43 has a limiting function. When the reciprocating screw 41 rotates in one direction, the slider 43 can move laterally in a straight line. The water guide pipe 44 is fixedly installed at the bottom of the slider 43, and the spray head 45 is fixedly installed on the water guide pipe 44. The water guide pipe 44 and the spray head 45 move synchronously with the slider 43. The fixed water pipe 46 is fixedly installed through the top of the support shell 2. A water supply pipe 47 is provided between one end of the fixed water pipe 46 and the water guide pipe 44. The other end of the fixed water pipe 46 is connected to an external water supply device. Generally, it includes components such as a water pump, water tank, and water pipes. The water supply equipment is a common piece of equipment in existing systems and will not be described in detail here. The linkage unit 5 is connected to the stirring shaft 11 and the reciprocating screw 41 respectively. As the key part connecting the stirring shaft 11 and the reciprocating screw 41, the linkage unit 5 transmits the power of the stirring shaft 11 to the reciprocating screw 41, so that the moving spray unit 4 can work synchronously with the stirring shaft 11, thereby achieving uniform spraying of materials during the mixing process and improving mixing efficiency and mixing quality.

[0028] Specifically, the linkage unit 5 includes a drive shaft 51, two first bevel gears 52 and two second bevel gears 53. The two ends of the drive shaft 51 are rotatably connected to the top and bottom of the protective shell 3, respectively. The two first bevel gears 52 are fixedly mounted on one end of the reciprocating screw 41 and one end of the stirring shaft 11, respectively. The two second bevel gears 53 are fixedly mounted on the drive shaft 51, and the two first bevel gears 52 mesh with the two second bevel gears 53, respectively. The first bevel gears 52 and the second bevel gears 53 are used to transmit the power of the stirring shaft 11 when it rotates to the drive shaft 51.

[0029] Specifically, the uniform spraying structure also includes a humidity detector 6, which is fixedly installed on the right side of the mixer body 1, and the probe of the humidity detector 6 is located inside the mixer body 1. The humidity detector 6 is used to detect the humidity of the material inside the mixer body 1 in real time. When the specified mixing humidity is reached, it will control the external water supply equipment to stop supplying water.

[0030] Specifically, there are two spray heads 45, which are arranged one on the left and one on the right, improving the comprehensiveness and efficiency of the spraying.

[0031] Specifically, the water supply pipe 47 is a flexible hose, and the length of the water supply pipe 47 is greater than the maximum displacement distance of the slider 43 from the center position of the reciprocating screw 41 to the leftmost or rightmost end, so as to ensure that the water supply pipe 47 adapts to the reciprocating motion of the mobile spray unit 4 during the spraying process.

[0032] Specifically, the length of the support shell 2 is the same as the length of the mixer body 1 to ensure comprehensive spraying.

[0033] Specifically, the reciprocating screw 41 is connected to the support shell 2 through a sealed bearing. The outer ring of the sealed bearing is fixedly connected to the support shell 2, and the inner ring of the sealed bearing is interference-fitted with the reciprocating screw 41, which improves the stability of the reciprocating screw 41 during rotation.

[0034] Working principle: After the stirring shaft 11 is started, its rotational power is transmitted to the reciprocating screw 41 through the linkage unit 5. The transmission shaft 51 in the linkage unit 5 is connected to two first bevel gears 52 and two second bevel gears 53. The power of the stirring shaft 11 is converted into the rotation of the reciprocating screw 41 through gear meshing.

[0035] When the reciprocating screw 41 rotates, the spiral groove on its surface engages with the spiral cam inside the slider 43, causing the slider 43 to perform linear reciprocating motion under the constraint of the limiting guide rod 42. The limiting guide rod 42 ensures the linearity of the slider 43's movement trajectory and prevents lateral deviation. A water guide pipe 44 and a spray head 45 are fixed at the bottom of the slider 43. As the slider 43 reciprocates, the spray head 45 moves left and right inside the mixer to spray the material evenly. Water is supplied to the spray head 45 through external water supply equipment, a fixed water pipe 46, a water delivery pipe 47, and the water guide pipe 44.

[0036] The humidity detector 6 plays a crucial role in the material mixing process inside the mixer, monitoring changes in material humidity in real time. As the mixing process progresses, when the humidity detector 6 detects that the material humidity is close to the preset humidity threshold, the system automatically adjusts the water pump in the external water supply equipment to supply water at a slower rate. This slow water supply control strategy helps to accurately control humidity and prevent the material humidity from exceeding the specified standard.

[0037] Once the humidity detector 6 detects that the material humidity has reached the set target value, it immediately sends a control signal to the external water supply equipment. Upon receiving this signal, the water pump in the water supply equipment will respond quickly and stop supplying water. This automated control mechanism ensures that the humidity of the mixture can be precisely controlled within the predetermined range, thereby guaranteeing the stability and consistency of the final product's quality.

[0038] This humidity control system not only prevents material quality degradation due to improper humidity, but also saves water resources, reduces energy consumption, improves production efficiency, and reduces the labor intensity of operators.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
