Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0020] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Reference Figure 1~Figure 5 , which is the first embodiment of the present invention, proposes a storage bin rotary unloading device, including a hopper 1; a rotating shaft 2 is horizontally rotatably arranged in the hopper 1; a cross tool holder 3 is arranged on the rotating shaft 2, and the cross tool holder 3 is used to cut the material bag; one end of the connecting rod 4 is arranged on the rotating shaft 2; a material baffle plate 5 is arranged on the other end of the rotating shaft 2; a material unloading pipe 6 is arranged at the bottom of the hopper 1, and after the rotating shaft 2 rotates, the material baffle plate 5 blocks or cancels the blocking of the material unloading pipe 6.

[0023] In the above scheme, the hopper 1 is in an inverted cone shape, which is convenient for the materials to gather at the bottom. The rotating shaft 2 runs through the two side walls of the hopper 1. The cross knife holder 3 has a sharp edge and is used to quickly cut the bundles of bundled materials. The connecting rod 4 is a round steel bar, one end of which is vertically welded to the rotating shaft 2, and the baffle plate 5 at the other end can accurately correspond to the discharge pipe 6. The baffle plate 5 is an arc-shaped steel plate with a diameter slightly larger than the diameter of the discharge pipe 6. The baffle plate 5 can be rotated with the rotating shaft 2 to achieve the blocking and opening of the discharge pipe 6. The discharge pipe 6 is a steel pipe, which is vertically welded at the bottom center of the hopper 1. The pipe wall has a certain thickness to ensure that the material passes smoothly while having sufficient strength. The rotating shaft 2 rotates flexibly in the hopper 1, and the cross knife holder 3 can efficiently break the bag to prevent the material from agglomerating and affecting the discharge accuracy; the connecting rod 4 connects the rotating shaft 2 and the baffle plate 5 to achieve accurate control of the discharge pipe 6 on and off; the baffle plate 5 and the discharge pipe 6 cooperate closely to accurately control the discharge timing.

[0024] Working process: Put the material bag on the cross knife frame 3, the material bag is cut, and then the material quickly enters the hopper 1 and accumulates. Start the device, the rotating shaft 2 starts to rotate at a constant speed, and the cross knife frame 3 cuts and breaks up the possible packaged materials during the rotation of the rotating shaft 2, so that the materials are loosely distributed. When the cross knife frame 3 rotates, the feeding pipe 6 is opened. Whenever the cross knife frame 3 rotates to the top of the feeding pipe 6, the feeding pipe 6 is blocked. By intermittently controlling the on and off of the feeding pipe 6, the blocking phenomenon caused by excessive feeding can be prevented.

[0025] Compared with manual shovel batching, this device has a high degree of automation, which greatly improves the efficiency of material unloading and reduces labor costs; it accurately controls the timing and amount of material unloading, and greatly improves the measurement accuracy compared with manual batching, reducing product quality fluctuations caused by batching errors.

[0026] Furthermore, it also includes a mounting cylinder 12: the mounting cylinder 12 is arranged in the discharge pipe 6, the mounting cylinder 12 and the discharge pipe 6 are coaxially arranged, and the outer wall of the mounting cylinder 12 and the inner wall of the discharge pipe 6 are the discharge channel 602; the sleeve 13 rotates and is slidably sleeved on the outer wall of the mounting cylinder 12; the top seat 10 is arranged on the top of the sleeve 13; there are a plurality of paddle blades 11, and the plurality of paddle blades 11 are arranged at intervals on the outer wall of the sleeve 13. After the sleeve 13 rotates, the paddle blades 11 are used to stir the material in the discharge channel 602.

[0027] In the above scheme, a stable material discharge channel 602 is formed between the installation cylinder 12 and the material discharge pipe 6, the sleeve 13 rotates and slides flexibly, the top seat 10 is fixed in position, and the paddle blades 11 are designed and arranged according to the principles of fluid mechanics to enhance the material flow control ability. It should be noted that the blades can be adjusted to a deflection angle as needed, and can be adjusted manually before placing the material bag.

[0028] Working process: When the material is discharged from the hopper 1 through the discharge pipe 6, the driver 14 drives the sleeve 13 to rotate, and the paddle blade 11 rotates accordingly, using the friction between the blade and the material and its own inclination angle to stir the material in the discharge channel 602 to prevent material blockage and make the discharge more uniform and continuous. Further optimize the discharge fluidity, avoid material accumulation and blockage in the pipe, ensure the continuity of ingredients, reduce production stagnation caused by interruption of discharge, and improve overall production efficiency; uniform discharge helps to more accurately control the material ratio per unit time, improve product quality stability; reduce equipment loss and maintenance costs caused by material blockage and cleaning.

[0029] Furthermore, it also includes a driver 14, which is arranged at the bottom of the mounting tube 12; one end of the connecting shaft 21 is arranged on the output end of the driver 14; the first bite disk 19 is arranged on the bottom surface of the top seat 10, and the first bite disk 19 is located in the mounting tube 12, and the first bite disk 19 has a first tooth body 1901; the second bite disk 20 is arranged on the other end of the connecting shaft 21, and the second bite disk 20 is located in the mounting tube 12, the first bite disk 19 and the second bite disk 20 are coaxially arranged, and the second bite disk 20 has a second tooth body 2001, the structure of the first tooth body 1901 is the same as the structure of the second tooth body 2001, and the first tooth body 1901 and the second tooth body 2001 are meshed with each other.

[0030] In the above scheme, the driver 14 is a motor, which is installed on a steel frame or base at the bottom of the mounting tube 12. One end of the connecting shaft 21 is firmly connected to the output end of the driver 14 through a coupling to ensure stable power transmission. The first bite plate 19 and the second bite plate 20 are consistent in shape and specification. The first bite plate 19 is fixed to the center of the bottom surface of the top seat 10 by bolts or welding, and the second bite plate 20 is set at the other end of the connecting shaft 21. The two are coaxially arranged and well meshed.

[0031] Working process: The driver 14 starts to run, and the output torque drives the second bite plate 20 to rotate through the connecting shaft 21. Since the first tooth body 1901 and the second tooth body 2001 are meshed with each other, when the first tooth body 1901 and the second tooth body 2001 rotate in the forward direction (from the attached Figure 5 When the second bite disk 20 rotates, it drives the first bite disk 19 to rotate synchronously, thereby driving the sleeve 13 and the paddle blade 11 to rotate, and the rotation speed can be precisely controlled by adjusting the frequency of the driver 14 to match the mixing requirements of different materials. When rotating in the opposite direction, the second bite disk 20 will lift up the first bite disk 19 when rotating, and achieve up and down reciprocating movement. At this time, the material will be subjected to an effect different from the original rotation mixing of the paddle blade 11, and up and down movement mixing will be achieved. At the same time, the first bite disk 19 falls by itself when falling, and can also apply a vibration effect to the installation cylinder 12 and the discharge pipe 6, effectively preventing material blockage.

[0032] Furthermore, the longitudinal sections of the first tooth body 1901 and the second tooth body 2001 are both right-angled trapezoids, and the first tooth body 1901 and the second tooth body 2001 both have inclined surfaces. After the inclined surface of the first tooth body 1901 contacts the inclined surface of the second tooth body 2001, the second bite disk 20 pushes the first bite disk 19 upward; the first tooth body 1901 and the second tooth body 2001 also have straight surfaces. After the straight surface of the first tooth body 1901 and the straight surface of the second tooth body 2001 abut against each other, the second bite disk 20 drives the first bite disk 19 to rotate.

[0033] In the above solution, the longitudinal sections of the first tooth body 1901 and the second tooth body 2001 are in the shape of a right-angled trapezoid, and the inclined surfaces of the right-angled trapezoidal tooth bodies are used to achieve an upward lifting action.

[0034] Working process: In the initial state, the first tooth body 1901 and the second tooth body 2001 are in direct contact with each other to stably transmit the rotational power. When the material is blocked, the driver 14 reverses, and the inclined surface of the first tooth body 1901 contacts the inclined surface of the second tooth body 2001. Using the principle of inclined surface mechanics, the second bite plate 20 pushes up the first bite plate 19 to achieve the lifting and lowering of the first bite plate 19.

[0035] Furthermore, the top of the first tooth body 1901 and the top of the second tooth body 2001 are both arc transition surfaces.

[0036] In the above scheme, the arc transition surface at the top of the first tooth body 1901 and the top of the second tooth body 2001 has a high surface finish and no defects, ensuring a smooth transition during the tooth body meshing and separation process to avoid stress concentration. The arc transition surface optimizes the top structure of the tooth body, and compared with the right-angle edge, it reduces the instantaneous impact force of the tooth body contact, enhances the durability of the structure, and is conducive to maintaining good dynamic performance and reducing noise and vibration during high-speed rotation and clutch action.

[0037] Working process: When the bevels are butted, the arc transition surface can guide the gear body to butt smoothly, avoid rigid collision, make the first bite plate 19 and the second bite plate 20 move smoothly, and ensure the smoothness of transmission throughout the operation of the equipment. Effectively reduce the noise of equipment operation, improve the acoustic environment of the workplace; reduce the wear of the gear body, extend the service life of the bite plate, reduce the downtime caused by component replacement, and improve production continuity; smooth transition helps to improve transmission efficiency, reduce energy loss, and reduce equipment energy consumption costs.

[0038] Furthermore, it also includes a rotating body 16, the rotating body 16 has a socket part 15, the socket part 15 is slidably set on the connecting shaft 21, the second engaging disk 20 is connected to the driver 14 through the rotating body 16, and the outer wall of the rotating body 16 has a serpentine guide groove 1601; the telescopic rod 17 is arranged on the inner wall of the mounting tube 12; one end of the abutment rod 18 is arranged on the piston rod of the telescopic rod 17, and the other end is used to abut against the serpentine guide groove 1601. After the abutment rod 18 abuts against the serpentine guide groove 1601, the rotating body 16 rotates and moves back and forth up and down.

[0039] In the above scheme, the rotating body 16 is a cylinder, and the sleeve part 15 is a cylindrical structure. The sleeve part 15 moves up and down reciprocatingly with the connecting shaft 21 without relative rotation, and is loosely matched with the connecting shaft 21 to ensure smooth sliding. The serpentine guide groove 1601 ensures that the rotating body 16 can move up and down while rotating. The telescopic rod 17 uses a hydraulic telescopic rod 17, the cylinder body is welded and fixed to the inner wall of the mounting cylinder 12, and the end of the piston rod is connected to the abutment rod 18. The shape of the head of the abutment rod 18 is adapted to the curved surface of the serpentine guide groove 1601, and the material is wear-resistant and has good contact.

[0040] It is understandable that when a large amount of material is accumulated on the top of the top seat 10, the piston rod of the telescopic rod 17 can be controlled to extend to push the abutment rod 18 to abut against the serpentine guide groove 1601. At this time, even when the first bite disk 19 and the second bite disk 20 are directly abutted, a vibration effect can still be applied to the top seat 10 to increase the material discharge speed and prevent blockage.

[0041] Furthermore, the top of the feed pipe 6 is located above the bottom surface of the hopper 1, and the feed pipe 6 has a discharge trough 601, and also includes an inner lining tube 9, which is slidably sleeved on the inner wall of the feed pipe 6. After the inner lining tube 9 moves, it blocks or unblocks the discharge trough 601.

[0042] In the above scheme, the length of the inner liner 9 is half of the discharge pipe 6. After the inner liner 9 moves to the position of the discharge trough 601, the discharge trough 601 can be completely covered. The inner liner 9 and the discharge trough 601 of the discharge pipe 6 constitute a variable discharge structure, and the inner liner 9 slides flexibly to realize the selective blocking and opening of the discharge trough 601. It should be noted that since the top of the discharge pipe 6 extends out of the top of the bottom surface of the hopper 1 for a distance. Therefore, there will still be a certain amount of material around the outer wall of the discharge pipe 6 and between the bottom of the hopper 1, and the baffle plate 5 blocks the discharge pipe 6. At this time, most of the material has been discharged. By opening the discharge trough 601, the temporarily stored material can enter the discharge pipe 6 through the discharge trough 601, so as to realize the discharge of a small part of the material. Since the flow rate of the material is small at this time, the discharge amount can be accurately controlled. The material discharging speed can be increased by first discharging a large amount of materials quickly, and then the final material discharging amount can be controlled by discharging materials slowly through the discharge chute 601, so as to realize a combination of fast and slow material discharging speeds and finally realize accurate material discharging.

[0043] Furthermore, it also includes a spiral conveying pipe 8, which is arranged at the bottom of the hopper 1, and the inlet of the spiral conveying pipe 8 is connected to the bottom of the feeding pipe 6.

[0044] In the above scheme, the inlet of the spiral conveying pipe 8 is connected to the bottom of the feeding pipe 6 through a welded reducer section to ensure smooth material transition without jamming. The length of the spiral conveying pipe 8 is set according to the layout of the plant and the location of the subsequent process. The inclination angle is suitable for installation, which is conducive to the material moving forward by gravity and the propulsion force of the spiral. The spiral conveying pipe 8 is integrated into the rear end of the feeding device to build a continuous material conveying link. The spiral structure characteristics are used to stably transmit the output material of the feeding pipe 6, expand the flexibility of material conveying distance and direction, and adapt to the complex production process space layout of the steel plant.

[0045] Working process: The material falls from the hopper 1 into the spiral conveying pipe 8 through the discharge pipe 6. As the spiral blades rotate, the material is continuously conveyed forward along the axial direction of the spiral pipe under the action of the rotating friction force and its own gravity component until it reaches the feed port of the designated production link. The conveying speed can be controlled by adjusting the speed of the spiral pipe drive motor.

[0046] Seamlessly connect unloading and subsequent production processes to avoid dust and loss in the material transfer process; long-distance, directional and stable transportation ensures timely and sufficient supply of materials, improves the continuity of the production process, and reduces production delays caused by poor material transfer; closed spiral transportation reduces dust pollution, which is in line with the concept of environmentally friendly and efficient production.

[0047] Furthermore, it also includes a plurality of cross bars 7, which are arranged on the connecting rod 4 at intervals. After the connecting rod 4 moves, the cross bars 7 are used to stir the materials.

[0048] In the above scheme, a plurality of cross bars 7 are provided, which are welded to the connecting rod 4 at a certain interval. The two ends of the cross bars 7 are polished into a suitable shape to reduce the residual material hanging, and the surface is passivated to enhance the corrosion resistance and adapt to the complex chemical environment in the silo. The cross bars 7 serve as auxiliary stirring parts of the connecting rod 4. The reasonable distribution increases the stirring range and effect. The structure is simple and practical, easy to install and maintain, and works with the rotating shaft 2 and the cross tool holder 3 to optimize the material state in the hopper 1 in all directions.

[0049] Working process: When the rotating shaft 2 rotates, the connecting rod 4 drives the cross bar 7 to move synchronously in a circular motion. The cross bar 7 shuttles between the materials, stirs the materials, promotes the uniform mixing of materials with different components, strengthens the stirring effect, and ensures the uniformity of the materials entering the discharge pipe 6. Improve the uniformity of material mixing, avoid affecting the accuracy of batching due to uneven local material concentration, and thus improve the consistency of steel product quality; reduce material agglomeration and precipitation, prevent the hidden danger of clogging the discharge pipe 6, ensure smooth and stable material discharge, and reduce the equipment failure rate; optimize the stirring function while not significantly increasing the complexity and cost of the equipment.

[0050] Furthermore, the vertical distance from the connecting rod 4 to the inclined surface of the hopper 1 is not less than the distance from the connecting rod 4 to the top of the discharge pipe 6 .

[0051] In the above solution, it is possible to prevent the connecting rod 4 and the material blocking plate 5 from being blocked by the inner wall of the hopper 1. It should be noted that the rotation speed of the rotating shaft 2 of the device is relatively slow.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
