[0076] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0077] like Figures 1-15 As shown, the suspended conveying system of the present invention includes a hoist 1, a material pipe 2, a material thrower 3, and a drive component 4.

[0078] like Figures 1-5 As shown, the feeder 3 includes a material tray 31, a deflector plate 32, and an adjusting component 33. The discharge port of the elevator 1 corresponds to the material pipe 2; the material tray 31 partially corresponds to the discharge port of the material pipe 2; multiple deflector plates 32 are provided on the material tray 31; the adjusting component 33 is used to drive the deflector plate 32 to swing, so as to adjust the tilt angle of the deflector plate 32; the driving component 4 is used to drive the feeder 3 to rotate.

[0079] As the above structure, the elevator 1 is used for lifting materials, so as to send the materials into the pipe 2, and then the materials fall to the tray 31 of the thrower 3 through the pipe 2, and then the tray 31 rotates under the driving of the driving member 4, so as to realize the throwing work;

[0080] In this way, the materials can be uniformly dispersed, so as to realize the 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 the paddle 32, so that when the thrower 3 rotates, the materials will be thrown outward along the paddle 32, so as to realize uniform material scattering;

[0082] In order to adjust the throwing range, the adjusting member 33 is arranged to adjust the angle of the paddle 32, so that the paddle 32 and the surface of the tray 31 form an angle structure;

[0083] Specifically, taking the paddle 32 as a rectangular plate as an example, in the normal state, one narrow edge of the paddle 32 corresponds to the surface of the tray 31, and after adjustment, the paddle 32 is inclined relative to the surface of the tray 31. At this time, the rotation direction of the tray 31 is set to be opposite to the inclination direction of the paddle 32, so that the force applied to the materials will be smaller, and then the throwing radius of the materials will be smaller, so as to realize the control of the throwing range;

[0084] In this way, the throwing range of the materials can be adjusted when the rotation speed of the thrower 3 is unchanged, which effectively realizes the dispersion of the materials, is conducive to ensuring the stability of the system operation, and fully utilizes the internal space of the container.

[0085] As shown in the figure, Figures 6-10 The thrower 3 further comprises a positioning ring 34, a connecting shaft 35 and a bearing seat 36. The tray 31 is in a circular truncated cone structure, and the positioning ring 34 is arranged corresponding to the small diameter end of the tray 31. The middle segment of the connecting shaft 35 is connected with the paddle 32, and one end of the connecting shaft 35 is rotationally connected with the positioning ring 34. The bearing seat 36 is rotationally connected with the connecting shaft 35, and the bearing seat 36 is fixedly connected with the tray 31.

[0086] As the above structure, the paddle 32 of the thrower 3 is rotationally arranged on the tray 31 through the connecting shaft 35, and the connecting shaft 35 is connected with the tray 31 through the bearing seat 36. In this way, the adjusting member 33 drives the connecting shaft 35 to rotate, so as to realize the angle adjustment of the paddle 32.

[0087] Among them, the plurality of connecting shafts 35 are rotationally connected with the positioning ring 34 at one end, so as to ensure the stability of the relative position of the overall structure, thereby ensuring the stability of the application of this structure;

[0088] Among them, the tray 31 is arranged in a circular truncated cone structure, so as to facilitate the throwing of the materials.

[0089] AsFigure 5 , Figure 6 and Figure 11 As shown, the adjusting component 33 includes a bevel gear disk 331, a bevel gear 332, and a first motor 333. The bevel gear disk 331 is rotatably connected to the material tray 31 and the positioning ring 34. The bevel gear 332 is disposed at the end of the connecting shaft 35 and meshes with the bevel gear disk 331. The first motor 333 is disposed inside the material tray 31, and the main shaft of the first motor 333 is connected to the bevel gear disk 331.

[0090] As described above, when the angle of the dial plate 32 is adjusted by 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 dial plate 32 can be driven to rotate, thereby achieving an adjustment at a certain angle. It has the advantages of simple structure and convenient adjustment.

[0091] In order to ensure structural stability, the bevel gear 332 extends locally into the positioning ring 34 to achieve rotational engagement between the two, which can further ensure the stability of the overall structure.

[0092] Specifically, the bevel gear 332 has cylindrical structures on both sides and a ring on the small diameter end of the material tray 31. In this way, the bevel gear 332 can rotate and cooperate with the positioning ring 34 and the ring on the material tray 31 by relying on the cylindrical structures on both sides to ensure the stability of the operation and reduce the force on the main shaft of the first motor 333.

[0093] like Figure 4 and Figure 6 As shown, the feeder 3 also includes a cover 37 and a drive shaft 38. The drive component 4 includes a second motor 41 and a drive gear 42. The cover 37 is fastened to the small diameter end of the material tray 31. The drive shaft 38 is connected to the cover 37. The second motor 41 is located on one side of the drive shaft 38. Both the drive shaft 38 and the main shaft of the second motor 41 are equipped with drive gears 42, and the two drive gears 42 mesh with each other.

[0094] As described above, in order to prevent the input of materials from affecting the structural stability of the adjusting component 33, a cover 37 is provided for fastening and protection, and a drive shaft 38 is connected through the cover 37, so that the feeder 3 can be driven to rotate by the drive 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, thereby driving the material thrower 3.

[0096] In some embodiments, the drive shaft 38 serves as a feed pipe;

[0097] Specifically, the drive shaft 38 has a hollow structure with a sealed bottom and an open structure at the end away from the cover 37. The end of the drive shaft 38 closest to the cover 37 has an opening on the side, so that materials can be input from above the drive shaft 38 and output from below through the side opening, thus allowing the materials to fall onto the material tray 31. This structure further achieves integration and simplification, which is conducive to reducing costs.

[0098] Specifically, in this embodiment, the top end of the drive shaft 38 is connected to the elevator for feeding through a rotary joint, and the feeder 3 can be installed on the trolley to achieve a wider range of material distribution.

[0099] Specifically, in this example, the drive shaft 38 has a built-in conical feed column to facilitate the output of materials through the side opening of the drive shaft 38. Combined with the centrifugal force generated by the drive shaft 38, this is more conducive to the discharge of materials.

[0100] like Figure 12 As shown, the cover 37 includes an annular plate 371, a protrusion 372, and a connecting portion 373. The annular plate 371 fits against the positioning ring 34, and the annular plate 371 and the positioning ring 34 are slidably engaged. Multiple protrusions 372 and connecting portions 373 are provided, and multiple protrusions 372 and connecting portions 373 surround the annular plate 371, with the protrusions 372 and connecting portions 373 spaced apart. The protrusions 372 correspond to the connecting shaft 35. The connecting portions 373 are connected to the material tray 31.

[0101] As described above, the housing 37 is provided with an annular plate 371, which can hold the positioning ring 34 and achieve a sliding fit between the two, thus further ensuring the relative position stability of each component; at the same time, the annular plate 371 is used to connect the drive shaft 38.

[0102] The cover 37 is also provided with a protrusion 372 and a connecting part 373. The protrusion 372 engages with the connecting shaft 35 and the bevel gear 332 to ensure good protection.

[0103] The connecting part 373 is used to connect with the material tray 31, and then realizes the suspension and hoisting structure of this suspension conveying system through the drive shaft 38;

[0104] The cover 37 is composed of a ring plate 371, a protrusion 372 and a connecting part 373, forming an irregular structure. This irregular structure gives the cover 37 good structural strength. Thus, the connection of the drive shaft 38 through the ring plate 371 can ensure stability during application.

[0105] like Figure 8As shown, the bearing housing 36 includes a base 361 and a top cover 362. The base 361 is disposed on the material tray 31. The top cover 362 is located inside the protrusion 372, and the top cover 362 and the cover 37 are configured as an integral structure and are connected to the base 361. The connecting shaft 35 is rotatably disposed between the base 361 and the top cover 362.

[0106] As described above, the bearing housing 36 is designed as a split structure, which allows the base 361 of the bearing housing 36 to be integrated onto the tray 31, and the top cover 362 to be directly integrated onto the housing 37. This enables the top cover 362 to cooperate with the base 361 when assembling the housing 37, thereby limiting the connection shaft 35. This simplifies the overall structure and improves the convenience of integration.

[0107] Specifically, bearing seats 36 are provided at both ends of the connecting shaft 35. The top cover 362 of the bearing seat 36 near the positioning ring 34 can be integrated with the cover 37.

[0108] In some embodiments, the connecting shaft 35 is rotatably engaged with the positioning ring 34 and is axially positioned. This axial positioning has a certain axial displacement stroke, so that the connecting shaft 35 can be pushed into the positioning ring 34 a portion first. This facilitates the other end of the connecting shaft 35 to be inserted into the bearing seat 36 away from the positioning ring 34. Specifically, the bearing seat 36 here is simplified as a ring structure.

[0109] The cement silo of the present invention includes the above-described suspended conveying system, and also includes a tank body 5, a bridge frame 6, and a scraper assembly 7.

[0110] like Figure 1 As shown, the cable tray 6 is installed on the tank body 5; the material pipe 2, the ejector 3 and the drive unit 4 are suspended on the cable tray 6, and the material pipe 2 and the ejector 3 extend into the tank body 5; the elevator 1 is installed on one side of the tank body 5.

[0111] As described above, the cable tray 6 is used for personnel passage to facilitate the operation and maintenance of the cement silo tank 5;

[0112] Among them, the material pipe 2, the ejector 3 and the drive unit 4 are directly suspended on the bridge frame 6, and the material pipe 2 and the ejector 3 extend into the tank 5, thereby realizing the conveying and dispersion of cement. At the same time, this structure also facilitates maintenance work.

[0113] The elevator 1 is used to lift the cement so that it can be fed into the material pipe 2.

[0114] like Figure 3As shown, the scraping assembly 7 includes a top frame 71, a bottom frame 72, a winding motor 73, and a cable 74. The top frame 71 and the bottom frame 72 are arranged opposite to each other inside the tank body 5, and the bottom frame 72 is rotatably connected to the tank body 5. Multiple winding motors 73 are provided 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] As described above, the wall scraping component 7 is used to clean the cement near the inner wall of the tank 5, which can disperse the hardened cement.

[0116] Specifically, in the cement silo, the cement near the inner wall is prone to caking. At this time, the drive unit drives the base frame 72 to rotate, and the base frame 72 pulls the cable 74. The winding motor 73 releases the cable 74 at the same time to prevent the cable 74 from breaking. In this way, with the rotation of the base frame 72, the cable 74 will cut and disperse the cement, thereby solving the caking problem.

[0117] In practical applications, when there is a certain amount of cement in the tank 5, the scraping component 7 is activated periodically, and the cement is stirred by the cable 74, which can effectively reduce the occurrence of caking problems.

[0118] Specifically, the base frame 72 is configured as a gear ring structure and driven by a motor and gears. Furthermore, larger diameter rings are provided on both sides of the gear ring structure. The two rings slide and fit with the inner wall of the tank 5 to achieve a sliding seal. At the same time, grooves are cut on the tank wall of the tank 5 corresponding to the gear ring structure, and a motor and gears are provided on the outer side of the tank 5 so that the gears mesh with the gear ring structure. The rotation drive of the base frame 72 can be achieved by the motor and gears.

[0119] like Figures 13-15 As shown, when the base frame 72 rotates, the cable 74 not only rotates around the circumference of the tank body 5, but also moves towards the center of the tank body 5, which can ensure a good cutting effect and reduce the problem of cement slabs not being discharged.

[0120] In some embodiments, the top frame 71 is also configured as a rotatable structure and is driven to rotate by a motor and gears, so that the top frame 71 and the bottom frame 72 can rotate synchronously, so that the cable 74 scrapes the cement near the tank wall. Alternatively, the top frame 71 or the bottom frame 72 can be rotated at a certain angle first, and then the top frame 71 and the bottom frame can rotate synchronously. As the cable is misaligned and contracts inward, this can further stir a larger area of ​​cement.

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

[0122] like Figure 2As shown, the tank 5 includes an upper tank 51, a variable diameter tank 52, a lower tank 53, and an airbag 54. The upper tank 51, the variable diameter tank 52, and the lower tank 53 are connected in sequence. The diameter of the variable diameter tank 52 is larger than that of the upper tank 51, and the lower tank 53 is configured as a conical structure. The airbag 54 is disposed on the inner wall of the variable diameter tank 52.

[0123] As described above, the tank body 5 is divided into three main parts: the upper tank body 51, the variable diameter tank body 52, and the lower tank body 53, which improves the ease of assembly of the tank body 5.

[0124] Among them, the diameter of the variable-diameter tank 52 is larger, so that it can accommodate the air bladder 54. When cement caking occurs, air can be injected into the air bladder 54 to crack the cement caking on the tank wall, thereby further improving the convenience of cement discharge.

[0125] Meanwhile, during the cement discharge process, the airbag 54 can be continuously pressurized to push the cement on the tank wall toward the center, thereby solving the problem that the cement discharge at the outlet of the existing cement silo is fast, while the cement discharge at the tank wall is slow and difficult to discharge.

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