[0036] Please refer to Figures 1-8 , the raw material block conveying all-in-one machine for cement foam board production is mainly composed of a frame 1, a charge bin 2, a breaking device 4 and a feeding device 5. The frame 1 serves as the supporting framework of the entire device and provides a stable mounting foundation for other components to ensure the overall stability of the device during operation. The charge bin 2 is placed on the frame 1 and is designed with two different shapes, an upper part and a lower part. The upper part is funnel-shaped, which facilitates the smooth entry of cement raw materials from different angles and directions, reducing the accumulation and jamming of raw materials. The lower part is a hollow rectangular shape, and a charge port 3 is provided at the lower part, which can smoothly guide the broken cement raw materials into the feeding device 5.

[0037] The breaking device 4 is composed of a breaking motor 401, a first speed reducer 402, a rotating shaft 403, a hollow square tube 404, a connecting sleeve 405, a breaking blade assembly 406 and a material separating frame 407. The rotating shaft 403 is tightly connected with the lower part of the material falling bin 2 through a bearing with a seat, which can ensure the stability of the rotating shaft 403 during high-speed rotation and effectively bear various forces generated during breaking. The connecting sleeve 405 is provided with two connecting sleeves which are fixedly arranged at the two ends of the rotating shaft 403, and the hollow square tube 404 is fixedly connected with the two connecting sleeves 405, so that the hollow square tube 404 can rotate stably synchronously with the rotating shaft 403. The breaking blade assembly 406 is provided with multiple groups, which are uniformly and fixedly connected with the outer wall of the hollow square tube 404 to form a full-range and multi-angle breaking working area. The breaking blade assembly 406 includes a specially designed first breaking blade 406a and three carefully laid second breaking blades 406b, and one first breaking blade 406a and three second breaking blades 406b are fixedly arranged on the four faces of the hollow square tube 404, respectively. This layout can efficiently break the cement blocks under the driving of the rotating shaft 403, and improve the breaking efficiency and the uniformity of the breaking effect. The material separating frame 407 is provided with multiple partitions 408, and a rectangular hollow 409 is formed between two adjacent partitions 408. The material separating frame 407 is arranged in the material falling bin 2 in an inclined manner, and one end thereof is fixedly connected with the inside of the material falling bin 2, and the other end is connected with the inner wall of the material falling bin 2 through a reinforcing rib 410. The first speed reducer 402 and the breaking motor 401 are fixedly arranged on the material falling bin 2, and the rotating shaft of the first speed reducer 402 is connected with one end of the rotating shaft 403 through a high-precision coupling. When the breaking motor 401 is started, power is transmitted to the rotating shaft 403 after accurate speed reduction by the first speed reducer 402, and then the hollow square tube 404 and the breaking blade assembly 406 thereon are driven to rotate at high speed to break the cement blocks. Each rectangular hollow 409 is provided with a breaking blade assembly 406, so that the cement blocks can be fully broken when passing through the material separating frame 407. During operation, the material separating frame 407 and the breaking blade assembly 406 form a close linkage structure. The inclination angle of the material separating frame 407 and the spacing of the partitions 408 are designed so that the cement blocks are first dispersed and guided by the material separating frame 407 during falling, and the larger cement blocks are broken in the main working area of the breaking blade assembly 406 below. At the same time, the reinforcing rib 410 not only stabilizes the material separating frame 407, but also affects the flow path and speed of the material to some extent, and cooperates with the material separating frame 407 to make the material more orderly enter the action range of the breaking blade assembly 406, thereby improving the breaking efficiency and uniformity.

[0038] The feeding device 5 is located at the bottom of the material falling bin 2, which functions to transport the broken cement raw materials to the subsequent mixing and stirring device, ensuring the continuity and stability of the entire production process. The feeding device 5 is composed of a machine shell 501, a rotating shaft 502, a spiral blade 503, a conveying motor 504 and a second speed reducer 505. The machine shell 501 serves as the external protection and material channel of the feeding device 5, and is provided with a feeding port 506 and a discharging port 507. The feeding port 506 is precisely connected with the material falling port 3 on the material falling bin 2, ensuring that the broken cement raw materials can enter the feeding device 5 without any obstruction. The two ends of the rotating shaft 502 are connected with the machine shell 501 through bearings, which can ensure the stability of the rotating shaft 502 during rotation, effectively reduce the friction resistance and reduce energy loss. The spiral blade 503 is fixedly arranged on the outer wall of the rotating shaft 502. When the conveying motor 504 is started, the power is transmitted to the rotating shaft 502 after being reasonably reduced by the second speed reducer 505, and the rotating shaft 502 drives the spiral blade 503 to rotate synchronously. The spiral blade 503 pushes the cement raw materials entering from the feeding port 506 along the channel inside the machine shell 501 to the discharging port 507 through its unique spiral structure, thereby realizing the stable conveying of the cement raw materials. The conveying motor 504 and the second speed reducer 505 are connected in a scientific manner, and the conveying motor 504 is fixedly arranged at the end of the machine shell 501 away from the material falling bin 2 through the second speed reducer 505. This ensures the uniformity and stability of the materials during conveying, preventing problems such as material blockage or incomplete conveying caused by excessive conveying speed.

[0039] The material falling bin 2 is also provided with a bag breaking partition plate 6 for conveniently breaking the cement packaging bags, and a plurality of material falling holes 7 are arranged on the bag breaking partition plate 6. In actual production process, the cement raw materials are often packaged and transported in packaging bags. When the cement with packaging bags is poured into the material falling bin 2, the bag breaking partition plate 6 can automatically cut the packaging bags during the falling process of the cement, so that the cement falls into the material falling bin 2 through the material falling holes 7, avoiding the cumbersome process of manual bag breaking, and greatly improving the production efficiency and automation degree.

[0040] The material falling bin 2 is also provided with a dust cover 8 connected with the material falling bin 2 through a hinge. During the loading, unloading and processing of the cement raw materials, a large amount of dust is inevitably generated. The dust cover 8 can be tightly covered above the material falling bin 2 through the flexible rotation of the hinge during the non-operation of the equipment or the interval of material loading and unloading, effectively blocking the dust from flying out, reducing the pollution to the production environment, protecting the health of the operating personnel, and also being conducive to keeping the production workshop clean and sanitary.

[0041] The middle part of the shell 501 is also connected with the rack 1 through the connecting piece. This connection further enhances the stability of the feeding device 5 during operation, especially when facing large conveying capacity or high conveying pressure, effectively preventing the feeding device 5 from shaking or shifting due to uneven force, ensuring that the cement raw materials can be stably conveyed from the inlet 506 to the discharge port 507 according to the predetermined conveying trajectory and speed, and improving the reliability and service life of the feeding device 5.

[0042] A sieve 9 is also provided in the material falling bin 2, which is arranged obliquely above the crushing device 4 and is fixedly connected to one side of the upper end of the material falling bin 2 and the end of the material separating frame 407 close to the reinforcing rib 410. After the cement raw materials enter the material falling bin 2, they will first be preliminarily screened by the sieve 9. The cement that is not cemented or is slightly cemented can directly pass through the mesh of the sieve 9, and then according to the particle size and gravity, part of it will directly fall into the feeding device 5, and the other part will finally fall into the feeding device 5 through the rectangular hollows 409 between the separating strips 408 of the material separating frame 407 and the material falling channels between the reinforcing ribs 410; while the cement that is severely cemented will be blocked by the sieve 9 and fall from the surface of the sieve 9 into the crushing device 4 for crushing. The arrangement of the sieve 9 can preliminarily classify the cement raw materials, so that cement raw materials in different states can take the most suitable processing path, further optimizing the working process of the entire equipment and improving the production efficiency.

[0043] The reinforcing rib 410 is provided with a plurality of reinforcing ribs 410, and a material falling channel is provided between two adjacent reinforcing ribs 410. The cement that is not cemented or is slightly cemented can fall into the feeding device 5 from the material falling channel. The reinforcing rib 410 not only plays a role in stabilizing the material separating frame 407 and ensuring that it will not deform or be damaged in a long-term and high-intensity working environment, but also, by reasonably arranging the material falling channel, allows the cement that is not cemented or is slightly cemented to directly fall into the feeding device 5 without passing through the crushing device 4, avoiding unnecessary crushing procedures, reducing equipment wear and energy consumption, and improving the processing efficiency and material throughput of the entire equipment.

[0044] Working principle:

[0045] The cement raw materials with cement packaging bags are placed above the material falling bin 2 and are subjected to bag breaking treatment. Since the upper part of the material falling bin 2 is funnel-shaped, it is beneficial for the raw materials to converge and enter. When the cement falls, the bag breaking partition plate 6 on the material falling bin 2 plays a role, and the cement smoothly falls into the inside of the material falling bin 2 through the material falling hole 7 of the bag breaking partition plate 6, realizing material falling. At the same time, the dust cover 8 can block dust from being blown out to a certain extent, reducing the pollution of the production environment.

[0046] The cement raw material entering the material falling bin 2 firstly reaches the screen 9. The cement which is not cemented or is slightly cemented can directly pass through the screen 9. A part of the cement directly falls into the feeding device 5 under the action of gravity, and the other part of the cement can be temporarily stayed in the material falling bin 2 or pushed by the subsequent cement raw material, pass through the rectangular hollow 409 between the partition strips 408 of the material separating frame 407 and the falling channel between the adjacent reinforcing ribs 410 and finally fall into the feeding device 5. The cement which is seriously cemented is blocked by the screen 9 and falls on the surface of the screen 9 into the breaking device 4 for processing.

[0047] The power generated by the breaking motor 401 is accurately decelerated by the first speed reducer 402 and then transmitted to the rotating shaft 403, so as to drive the hollow square tube 404 and the breaking blade assembly 406 on the hollow square tube 404 to rotate at high speed, which are fixedly connected with the rotating shaft 403 through the connecting sleeve 405. The first breaking blade 406a and the three second breaking blades 406b in the breaking blade assembly 406 are respectively fixed on the four faces of the hollow square tube 404, so as to impact and cut the cement block from different directions and gradually break the cement block into smaller particles.

[0048] The conveying motor 504 of the feeding device 5 is started, the power is transmitted to the rotating shaft 502 through the second speed reducer 505, so as to drive the spiral blade 503 to rotate. The cement raw material falling into the feeding device 5 from the material falling port 3 of the material falling bin 2 is pushed along the internal channel of the casing 501 to the material discharging port 507 by the spiral blade 503, so as to realize stable conveying.
