[0052] The suspension conveying system, cement silo and its application method of the present invention have the following beneficial effects compared with the prior art:

[0053] (1) By setting the elevator and the material pipe, the material can be conveyed to the thrower. In this way, the material can be dispersed by driving the thrower to rotate by the driving member, and the material can completely fill the material silo, so as to make full use of the internal space of the material silo; at the same time, the thrower is provided with a baffle plate. By changing the angle of the baffle plate through the adjusting member, the dispersion force of the material can be adjusted, so that the dispersion range of the material can be adjusted when the rotation speed of the thrower remains unchanged. It is not only convenient to apply, but also conducive to ensuring the stability of the system operation;

[0054] (2) In the structure of the thrower, the baffle plate is rotatably arranged on the material tray through the connecting shaft.

[0056] (4) The bearing seat is composed of a base and a top cover. In this way, the top cover can be integrally arranged with the housing. After installing the housing, on the one hand, it can realize the positioning of the connecting shaft, on the other hand, it can realize the covering and protection of the adjusting member, and on the third hand, it realizes the connection with the transmission shaft, which has the advantages of simple structure and convenient assembly;

[0058] (6) By setting the tank body into three parts: an upper tank body, a variable-diameter tank body, and a lower tank body, and arranging an airbag in the variable-diameter tank body, the caked materials on the tank wall can be cracked by inflating the airbag, thereby further improving the convenience of discharging the materials. At the same time, during the material discharging process, the airbag can continuously apply pressure to push the materials on the tank wall towards the center, enabling the discharge of this part of the materials, thus solving the problem that the materials at the discharge port of the existing material storage are discharged quickly, while the materials at the tank wall are not easily discharged.

Detailed implementation manners

[0076] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0077] As Figures 1 to 15 shown, the suspension conveying system of the present invention includes an elevator 1, a material pipe 2, a throwing device 3 and a driving member 4.

[0078] As Figures 1 to 5 shown, the throwing device 3 includes a material tray 31, a baffle 32 and an adjusting member 33. Among them, the discharge port of the elevator 1 corresponds to the material pipe 2; a part of the material tray 31 corresponds to the discharge port of the material pipe 2; a plurality of baffles 32 are arranged on the material tray 31; the adjusting member 33 is used to drive the baffle 32 to swing to adjust the inclination angle of the baffle 32; the driving member 4 is used to drive the throwing device 3 to rotate;

[0079] In the above structure, the elevator 1 is used to lift materials and feed them into the material pipe 2. Subsequently, the materials fall through the material pipe 2 onto the tray 31 of the throwing device 3. Then, driven by the driving member 4, the tray 31 rotates to achieve the throwing operation.

[0080] In this way, the materials can be evenly dispersed, so as to achieve uniform filling of the materials in the container and avoid wasting the internal space of the container.

[0081] Specifically, the tray 31 is provided with a deflector 32. In this way, when the throwing device 3 rotates, the materials will be thrown out along the deflector 32, thus achieving uniform spreading of the materials.

[0082] In order to adjust the throwing range, an adjusting member 33 is provided to adjust the angle of the deflector 32 so that the deflector 32 forms an angular structure with the surface of the tray 31.

[0083] Specifically, taking the deflector 32 as a rectangular plate as an example, in the normal state, a narrow side of the deflector 32 corresponds to the surface of the tray 31. After adjustment, the deflector 32 is inclined relative to the surface of the tray 31. At this time, if the rotation direction of the tray 31 is set to be opposite to the inclination direction of the deflector 32, the force applied to the materials will become smaller, and then the throwing radius of the materials will become smaller, so as to achieve the control of the throwing range.

[0084] In this way, when the rotation speed of the throwing device 3 remains unchanged, the adjustment of the dispersion range of the materials can be achieved, which effectively realizes the dispersion of the materials, is beneficial to ensuring the stability of the system operation, and makes full use of the internal space of the container.

[0085] As Figures 6 to 10 shown, the throwing device 3 further includes a positioning ring 34, a connecting shaft 35 and a bearing seat 36. Among them, the tray 31 is in a frustum shape structure, and the positioning ring 34 is arranged corresponding to the small-diameter end of the tray 31; the middle section of the connecting shaft 35 is connected to the deflector 32, and one end of the connecting shaft 35 is rotatably connected to the positioning ring 34; the bearing seat 36 is rotatably connected to the connecting shaft 35, and the bearing seat 36 is fixedly connected to the tray 31.

[0086] In the above structure, the deflector 32 of the throwing device 3 is rotatably arranged on the tray 31 through the connecting shaft 35, and the connecting shaft 35 and the tray 31 are connected through the bearing seat 36; in this way, when the adjusting member 33 drives the connecting shaft 35 to rotate, the angle adjustment of the deflector 32 can be achieved.

[0087] Among them, one end of each of the multiple connecting shafts 35 is rotatably connected to the positioning ring 34, so as to ensure the relative position stability of the overall structure and thus ensure the stability of the application of this structure.

[0088] Among them, the tray 31 is set in a frustum shape structure, so as to facilitate the throwing of the materials.

[0089] AsFigure 5 , Figure 6 and Figure 11 As shown in ,

[0090] , the adjusting member 33 includes a bevel gear disk 331, a bevel gear 332, and a first motor 333. Among them, the bevel gear disk 331 is rotatably connected to the material disk 31 and the positioning ring 34; the bevel gear 332 is arranged at the end of the connecting shaft 35, and the bevel gear 332 meshes with the bevel gear disk 331; the first motor 333 is arranged in the material disk 31, and the main shaft of the first motor 333 is connected to the bevel gear disk 331.

[0090] In the above structure, when adjusting the angle of the baffle 32 through the adjusting member 33, the first motor 333 drives the bevel gear disk 331 to rotate. Then, through the meshing of the bevel gear disk 331 and the bevel gear 332, all the connecting shafts 35 and the baffle 32 can be driven to rotate, so as to achieve adjustment at a certain angle. It has the advantages of simple structure and convenient adjustment.

[0091] Among them, in order to ensure the structural stability, a part of the bevel gear 332 extends into the positioning ring 34 to realize the rotational cooperation between the two, which can further ensure the stability of the overall structure.

[0092] Specifically, both sides of the bevel gear 332 are set as cylindrical structures, and a circular ring is arranged at the small-diameter end of the material disk 31. In this way, the bevel gear 332 relies on the cylindrical structures on both sides to perform rotational cooperation with the circular ring on the positioning ring 34 and the material disk 31 to ensure the stability of the movement, and at the same time, the force on the main shaft of the first motor 333 can be reduced.

[0093] As Figure 4 and Figure 6 shown, the throwing device 3 further includes a housing 37 and a transmission shaft 38, and the driving member 4 includes a second motor 41 and a transmission gear 42. Among them, the housing 37 is buckled on the small-diameter end of the material disk 31; the transmission shaft 38 is connected to the housing 37; the second motor 41 is arranged on one side of the transmission shaft 38, and transmission gears 42 are arranged on both the transmission shaft 38 and the main shaft of the second motor 41, and the two transmission gears 42 mesh with each other.

[0094] In the above structure, in order to prevent the input of materials from affecting the structural stability of the adjusting member 33, a housing 37 is provided for buckling protection, and a transmission shaft 38 is connected through the housing 37. Then, the throwing device 3 can be driven to rotate by relying on the transmission shaft 38.

[0095] During operation, the second motor 41 drives the transmission gear 42 on the transmission shaft 38 to rotate through the transmission gear 42 on the main shaft, and the transmission of the throwing device 3 can be realized.

[0096] In some embodiments, the transmission shaft 38 serves as the feed pipe.

[0097] Specifically, the drive shaft 38 has a hollow structure with a sealed bottom end and an open structure at the end away from the housing 37. At the end of the drive shaft 38 near the housing 37, openings are made on the side, so that the material can be input from above the drive shaft 38 and output through the side openings at the lower part, thus enabling the material to fall onto the tray 31; this structure further realizes integration and simplification, which is beneficial to cost reduction.

[0098] Specifically, in this embodiment, the top end of the drive shaft 38 is connected to the elevator through a rotary joint for feeding, and the throwing device 3 can be arranged on the traveling crane to achieve a larger range of cloth laying.

[0099] Specifically, in this example, a conical material distribution column is built inside the drive shaft 38 to facilitate the output of the material through the side openings of the drive shaft 38. Combining with the centrifugal force generated by the drive shaft 38 is more conducive to the discharge of the material.

[0100] As Figure 12 shown, the housing 37 includes a ring plate 371, a convex portion 372, and a connecting portion 373. Among them, the ring plate 371 fits against the positioning ring 34, and the ring plate 371 is in sliding fit with the positioning ring 34; a plurality of convex portions 372 and connecting portions 373 are provided, and the plurality of convex portions 372 and connecting portions 373 surround the ring plate 371, and the convex portions 372 and the connecting portions 373 are spaced apart; the convex portion 372 corresponds to the connecting shaft 35; the connecting portion 373 is connected to the tray 31.

[0101] As described above, the housing 37 is provided with a ring plate 371, so that the ring plate 371 can be used to abut against the positioning ring 34 to achieve sliding fit between the two, which can further ensure the relative positions of the components are stable; at the same time, the ring plate 371 is used to connect the drive shaft 38.

[0102] Among them, the housing 37 is also provided with a convex portion 372 and a connecting portion 373. By buckling the convex portion 372 to the connecting shaft 35 and the bevel gear 332, a good protection effect can be ensured.

[0103] Among them, the connecting portion 373 is used to connect to the tray 31, and further realizes the suspension and hoisting structure of the present suspension conveying system through the drive shaft 38.

[0104] Among them, the housing 37 is composed of a ring plate 371, a convex portion 372, and a connecting portion 373, forming a special-shaped structure. This special-shaped structure enables the housing 37 to have good structural strength. Thus, by connecting the drive shaft 38 through the ring plate 371, the stability during application can be ensured.

[0105] As Figure 8As shown in the figure, the bearing housing 36 includes a base 361 and a top cover 362. Among them, the base 361 is arranged on the tray 31; the top cover 362 is located within the convex portion 372, and the top cover 362 and the housing 37 are provided as an integral structure and are connected to the base 361; the connecting shaft 35 is rotatably arranged between the base 361 and the top cover 362.

[0106] In the above structure, the bearing housing 36 is provided as a split structure. In this way, the base 361 of the bearing housing 36 can be integrated on the tray 31, and the top cover 362 can be directly integrated on the housing 37. Thus, when assembling the housing 37, the cooperation between the top cover 362 and the base 361 can be realized, and then the connecting shaft 35 can be limited. This is beneficial to simplifying the overall structure and improving the convenience of integration.

[0107] Specifically, bearing housings 36 are arranged at both ends of the connecting shaft 35. For the bearing housing 36 near the positioning ring 34, its top cover 362 can be integrated with the housing 37.

[0108] In some embodiments, the connecting shaft 35 is rotationally and axially positioned with the positioning ring 34. This axial positioning has a certain axial displacement stroke. In this way, the connecting shaft 35 can be first pushed into the positioning ring 34 by a part, which is convenient for the other end of the connecting shaft 35 to be inserted and matched with the bearing housing 36 away from the positioning ring 34; specifically, the bearing housing 36 here is simplified to be a circular ring structure.

[0109] The cement silo of the present invention includes the above-mentioned suspension conveying system, and also includes a tank body 5, a bridge 6 and a wall scraping assembly 7.

[0110] As Figure 1 shown in the figure, the bridge 6 is arranged on the tank body 5; the material pipe 2, the throwing device 3 and the driving member 4 are suspended on the bridge 6, and the material pipe 2 and the throwing device 3 extend into the tank body 5; the elevator 1 is arranged on one side of the tank body 5.

[0111] In the above structure, the bridge 6 is used for personnel to pass through, so as to facilitate the operation and maintenance of the tank body 5 of the cement silo.

[0112] Among them, the material pipe 2, the throwing device 3 and the driving member 4 are directly suspended on the bridge 6, and the material pipe 2 and the throwing device 3 extend into the tank body 5, so as to realize the conveying and dispersion of cement. At the same time, this structure is also convenient for the carrying out of maintenance work.

[0113] Among them, the elevator 1 is used to lift cement to send the cement into the material pipe 2.

[0114] As Figure 3As shown in the figure, the scraping wall assembly 7 includes a top frame 71, a bottom frame 72, a winding motor 73 and a cable 74. Among them, the top frame 71 and the bottom frame 72 are oppositely arranged in the tank body 5, and the bottom frame 72 is rotatably connected to the tank body 5; a plurality of winding motors 73 are arranged on the top frame 71; one end of the cable 74 is connected to the main shaft of the winding motor 73, and the other end is connected to the bottom frame 72;

[0115] With the above structure, the scraping wall assembly 7 is used to clean the cement near the inner wall of the tank body 5, and can realize the dispersion of the caked cement;

[0116] Specifically, in the cement silo, the cement near the inner wall is prone to caking problems. At this time, the bottom frame 72 is driven to rotate by the driving member, the bottom frame 72 will pull the cable 74, and the winding motor 73 will synchronously release the cable 74 to avoid breaking the cable 74. In this way, with the rotation of the bottom frame 72, the cable 74 will cut and disperse the cement, thus solving the caking problem;

[0117] In the actual application process, when there is a certain amount of cement in the tank body 5, the scraping wall assembly 7 is started regularly, and the cable 74 is relied on to stir the cement, which can effectively reduce the occurrence of caking problems;

[0118] Specifically, the bottom frame 72 is set as a toothed ring structure, and it can be driven by a motor and a gear; further, circular rings with larger diameters are arranged on both sides of the toothed ring structure, and the two circular rings are slidably matched with the inner wall of the tank body 5 and realize sliding sealing. At the same time, a groove is opened on the tank wall of the tank body 5 corresponding to the toothed ring structure, and a motor and a gear are arranged outside the tank body 5 so that the gear meshes with the toothed ring structure, and the rotation of the bottom frame 72 can be realized through the motor and the gear.

[0119] As Figures 13 to 15 shown, when the bottom frame 72 rotates, the cable 74 not only rotates along the circumference of the tank body 5, but also moves closer to the center of the tank body 5, so as to ensure a good cutting effect and thus reduce the problem that the caked cement cannot be discharged;

[0120] In some embodiments, the top frame 71 is also set as a rotatable structure and is driven to rotate by a motor and a gear. In this way, the top frame 71 and the bottom frame 72 can rotate synchronously, and the cable 74 can scrape the cement near the tank wall. Or the top frame 71 or the bottom frame 72 can be rotated by a certain angle first, and then the top frame 71 and the bottom frame rotate synchronously. Since the cable is misaligned and contracts inward, this can further stir a larger range of cement.

[0121] Specifically, the cable 74 is not limited to a linear structure and can be adjusted according to specific requirements.

[0122] As Figure 2As shown in the figure, the tank body 5 includes an upper tank body 51, a variable-diameter tank body 52, a lower tank body 53 and an airbag 54. Among them, the upper tank body 51, the variable-diameter tank body 52 and the lower tank body 53 are connected in sequence. The diameter of the variable-diameter tank body 52 is larger than that of the upper tank body 51, and the lower tank body 53 is arranged in a conical cylinder structure; the airbag 54 is arranged on the inner wall of the variable-diameter tank body 52;

[0123] In the above structure, the tank body 5 is divided into three main parts: an upper tank body 51, a variable-diameter tank body 52 and a lower tank body 53, which improves the convenience of assembling the tank body 5;

[0124] Among them, the diameter of the variable-diameter tank body 52 is larger, so that the airbag 54 can be accommodated. In this way, when the cement shows a caking problem, the airbag 54 can be inflated to crack the caked cement on the tank wall, thereby further improving the convenience of discharging the cement;

[0125] At the same time, during the cement discharging process, the airbag 54 can be continuously pressurized to push the cement on the tank wall towards the center, so as to solve the problem that the cement discharges quickly at the discharge port of the existing cement silo, while the cement at the tank wall discharges slowly and is not easy to discharge.

[0126] The application method of the cement silo of the present invention includes the following steps:

[0127] S1. When feeding, the elevator 1 is used to lift the cement and convey it into the material pipe 2,

[0128] S2. The cement falls from the material pipe 2 onto the throwing device 3,

[0129] S3. The driving member 4 drives the throwing device 3 to rotate, so as to evenly sprinkle the cement into the tank body 5,

[0130] S4. When discharging, the cement is output from the bottom of the tank body 5;

[0131] Among them, during the throwing process, the adjusting member 33 adjusts the inclination angle of the deflector 32 to change the throwing range;

[0132] Among them, when discharging, if a caking problem occurs, the driving member drives the chassis 72 to rotate, and at the same time the winding motor 73 continuously releases the cable 74 to disperse the caked cement with the cable 74.

[0133] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
