Description

Technical Field

[0001] This utility model relates to the technical field of cement material conveying and distribution equipment, and in particular to a cement chute material distribution device with a buffer mechanism. Background Technology

[0002] In the cement production and transportation process, cement materials need to be distributed to different processing or storage stations according to process requirements. Currently, traditional cement chute material distribution devices generally have the following drawbacks: Severe impact damage: The material directly and rigidly collides with the first distribution mechanism, and the resulting impact force can easily cause deformation of the first distribution mechanism and breakage of the cylinder piston rod, resulting in high equipment maintenance frequency and short service life. Insufficient distribution accuracy: The hinge structure design of the first distribution mechanism and the connecting rod is unreasonable. It is easy to get stuck when swinging, making it impossible to accurately control the material flow direction and making it difficult to meet the material distribution needs of multiple workstations. Lack of buffer protection: Without a dedicated buffer mechanism, the vibration caused by the impact of materials will be transmitted to the entire device, leading to a chain of failures such as loose frame and worn bearings, affecting the overall stability of the equipment.

[0003] To solve the above-mentioned technical problems, this utility model proposes a cement chute material distribution device with a buffer mechanism to achieve the goals of accurate distribution, buffering and vibration reduction, and extending equipment life. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cement chute material distribution device with a buffer mechanism, which solves the technical problems of traditional cement chute material distribution devices, such as equipment damage caused by rigid impact of materials, insufficient distribution accuracy due to swinging and jamming of the first distribution mechanism, and the impact of lack of buffer protection on equipment stability and service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cement chute material distribution device with a buffer mechanism includes a conveying mechanism and multiple collection boxes disposed below the conveying mechanism; The first and second distribution mechanisms are sequentially arranged above the conveying mechanism; Both the first and second distribution mechanisms include cylinders, the piston rod of the cylinder is connected to a connecting rod, and the connecting rod is hinged to the first distribution mechanism via a pin. The cylinder is equipped with a buffer mechanism, which includes a buffer plate. The buffer plate is connected to the cylinder's connecting block via a buffer connecting component, and the connecting block is connected to the connecting rod via a rotary joint.

[0006] Preferably, the conveying mechanism is a belt conveyor with baffles fixed on both sides and multiple material leakage holes on the conveyor belt.

[0007] Preferably, the number of collection boxes is three, and the three collection boxes are respectively set below different workstations of the conveying mechanism.

[0008] Preferably, a fixing block is fixed on the first distribution mechanism, the fixing block is hinged to the connecting rod by a pin, and a limit component is provided at the hinge.

[0009] Preferably, the cylinder is mounted on a bracket, and the bracket is fixed to the frame of the conveying mechanism.

[0010] Preferably, the buffer plate is an arc-shaped plate, and the buffer plate is fixedly connected to the connecting block through a buffer connecting component. The rotary joint is a ball joint structure, with one end connected to the connecting block and the other end connected to the connecting rod, so that the connecting rod can rotate within a certain angle. The first distribution mechanism and the second distribution mechanism have the same structure and are arranged sequentially above the conveying mechanism along the conveying direction of the conveying mechanism.

[0011] Compared with the prior art, the present invention has the following beneficial effects: High distribution accuracy: Through the coordinated action of the first and second distribution mechanisms, combined with the material leakage hole design of the conveyor belt of the conveyor mechanism, cement materials can be accurately guided to the collection boxes of different workstations, meeting the process requirements of multi-path material distribution. Significant buffering and vibration reduction effect: The buffer plate of the buffer mechanism works in conjunction with the buffer connection component to effectively absorb the impact energy of the material on the first distribution mechanism, avoid damage to the first distribution mechanism, cylinder and other components due to rigid impact, and greatly reduce the probability of equipment failure. Strong structural stability: The ball joint structure of the rotary joint allows the connecting rod to rotate flexibly, and the limiting component restricts the hinge angle, ensuring that the first distribution mechanism swings smoothly without jamming; the stable connection between the bracket and the conveyor frame, and the precise docking between the collection box and the lower surface of the conveyor belt, further enhance the overall structural stability of the device. Extended equipment lifespan: The wear-resistant design of the conveyor belt, the first distribution mechanism, and the buffer plate, combined with the impact absorption effect of the buffer mechanism, significantly reduces the wear and fatigue damage of the components, thus extending the overall service life of the equipment. Wide adaptability to various scenarios: The inclined belt conveyor structure, multi-station collection box layout and adjustable distribution mechanism of the device can adapt to material distribution scenarios of cement chute with an inclination angle of 15°-20° and different flow rates, making it highly practical and versatile.

[0015] This application provides a cement chute material distribution device with a buffer mechanism, which effectively solves the technical problems of traditional cement chute material distribution devices, such as equipment damage caused by rigid impact of materials, insufficient distribution accuracy due to swinging and jamming of the first distribution mechanism, and the impact of lack of buffer protection on equipment stability and service life. Example

[0016] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the overall technical solution in this application embodiment is as follows: To address the problems existing in the prior art, this utility model discloses a cement chute material distribution device with a buffer mechanism. The device aims to achieve precise distribution and impact buffering of cement materials through the cooperation of multiple distribution mechanisms and buffer structures. Its specific structure is as follows: The device includes, in sequence along the material conveying direction, a conveying mechanism 1, a first distribution mechanism 3 and a second distribution mechanism 4 located above the conveying mechanism 1, and a collection box 2 located below the conveying mechanism 1. The first distribution mechanism 3 and the second distribution mechanism 4 are arranged at intervals along the conveying direction of the conveying mechanism 1, and their structures are completely identical. Three collection boxes 2 are provided, corresponding to the inlet, middle, and outlet positions of the conveying mechanism 1, respectively. The upper opening of each collection box 2 is aligned with the lower surface of the corresponding conveying section of the conveying mechanism 1, and the lower opening is connected to a conveying pipe via a flange.

[0017] The conveying mechanism 1 is an inclined belt conveyor (inclination angle 15°-20°), and its main body includes a frame, a drive roller, a driven roller and a conveyor belt wrapped between the two rollers.

[0018] The conveyor belt is made of wear-resistant rubber and has multiple material leakage holes evenly distributed on its surface. The material leakage holes are arranged in rows along the width of the conveyor belt to achieve initial dispersion of materials during the conveying process. Baffles are vertically fixed to both sides of the conveyor belt. The baffles are made of Q235 steel plate and are fixed to the sides of the conveyor belt with bolts to prevent materials from spilling from both sides of the conveyor belt. The frame is made of channel steel welded together, and the bottom is fixed to the ground with expansion bolts. The shaft ends of the drive roller and the driven roller are mounted on the upright plates on both sides of the frame through bearing seats.

[0019] The collection box 2 is a cuboid structure with an opening at the top, and its length is the same as the width of the conveyor belt of the conveying mechanism 1.

[0020] The upper edge of the collection box 2 is folded outward to form a flange edge, which is fixed to the bottom crossbeam of the conveyor mechanism 1 frame by bolts to ensure that the gap between the collection box 2 and the lower surface of the conveyor belt does not exceed 5cm. The bottom center of the collection box 2 has a discharge port, and an external threaded connector is welded to the discharge port for connection with the internal threaded connector of the external conveying pipe.

[0021] Taking the first distribution mechanism 3 as an example, it includes a bracket 5, a cylinder 6, a connecting rod 10, the first distribution mechanism 3, a buffer mechanism, and auxiliary connecting parts.

[0022] Support 5: It is made of angle steel welded into a "door" shape. Its two legs are fixed to the upright plates on both sides of the frame of conveyor mechanism 1 by bolts. The crossbeam is located directly above the conveyor belt. Cylinder 6: It is horizontally mounted on the crossbeam of the bracket 5. The tail of the cylinder body of cylinder 6 is hinged to the crossbeam through the lug (the lug is welded to the crossbeam). The middle part of the cylinder body is connected to the buffer mechanism through the connecting block 9. One side of the connecting block 9 is fixed to the cylinder body of cylinder 6 by bolts, and the other side is provided with a spherical groove. Connecting rod 10: Made of round steel, one end of which is connected to the piston rod end of cylinder 6 by thread (the piston rod end is provided with external thread, and the corresponding end of connecting rod 10 is provided with internal thread hole), and the other end is connected to connecting block 9 through rotary joint 8; rotary joint 8 is a ball joint structure, the ball part of which is welded and fixed to the end of connecting rod 10, and the ball socket part is embedded in the spherical groove of connecting block 9, and the edge of the groove is provided with a retaining ring (to prevent the ball from falling off), so that connecting rod 10 can rotate around rotary joint 8 within a range of ±30°; First distribution mechanism 3: It is made of wear-resistant steel plate bent into an "L" shape, and the length of its horizontal section is consistent with the width of the conveyor belt; two fixing blocks 14 are welded to the lower surface of the horizontal section of the first distribution mechanism 3 near the end, and coaxial pin holes are opened on the fixing blocks 14. The end of the connecting rod 10 away from the cylinder 6 is inserted between two fixed blocks 14, and is hinged to the corresponding hole of the connecting rod 10 by a pin 13 passing through the pin hole of the fixed block 14; both ends of the pin 13 are provided with shoulders, and the outer side of the shoulders is fixed by a cotter pin (to prevent the pin 13 from moving axially). A limiting component 15 is provided at the hinge: the limiting component 15 consists of two arc-shaped limiting plates, which are welded to the outside of the two fixed blocks 14 respectively. The arc radius of the limiting plate matches the rotation trajectory of the connecting rod 10, and is used to limit the hinge angle (maximum swing angle 45°) between the connecting rod 10 and the first distribution mechanism 3.

[0023] The buffer mechanism is located on the side of the cylinder 6 near the first distribution mechanism 3, and includes a buffer plate 11 and a buffer connecting component 12.

[0024] Buffer plate 11: It is an arc-shaped steel plate (the arc matches the vertical section of the first distribution mechanism 3), with an arc radius of 20-30cm, a thickness of 3-5mm, and a 5-8mm thick rubber buffer layer pasted on the surface. Buffer connection component 12: includes four buffer springs and two connecting plates; one connecting plate is welded to the back (non-arc surface) of the buffer plate 11, and the other connecting plate is fixed to the side of the connecting block 9 away from the cylinder 6 by bolts; the four buffer springs are evenly distributed between the two connecting plates, and their ends are welded and fixed to the connecting plates respectively, so that the buffer plate 11 and the connecting block 9 form an elastic connection.

[0025] Work process: Cement material enters the conveyor belt through the feed end of conveying mechanism 1 and is conveyed towards the discharge end by the conveyor belt: In the initial state, the first distribution mechanism 3 and the second distribution mechanism 4 are both in a horizontal position (parallel to the conveyor belt), and the material is directly transported along the conveyor belt to the collection box 2 corresponding to the discharge end; When materials need to be distributed to the collection box 2 in the middle workstation, the cylinder 6 of the first distribution mechanism 3 is activated: the piston rod extends and pushes the connecting rod 10 to rotate around the rotary joint 8. The connecting rod 10 drives the first distribution mechanism 3 to swing upward (to form a 30° angle with the conveyor belt) through the pin 13. At this time, the material is blocked by the vertical section of the first distribution mechanism 3, and some of the material falls into the middle collection box 2 through the leakage hole of the conveyor belt. The remaining material continues to be transported with the conveyor belt. When it is necessary to distribute materials to the collection box 2 at the feeding end station, the cylinder 6 of the second distribution mechanism 4 is activated (the activation mode is the same as that of the first distribution mechanism 3). After the first distribution mechanism 3 swings, it blocks the subsequent materials, causing them to fall into the collection box 2 at the feeding end through the leakage hole at the corresponding position. When the material comes into contact with the first distribution mechanism 3, the impact force is transmitted in sequence to the buffer plate 11 and the buffer spring of the buffer connecting component 12. The spring is compressed and deformed to absorb the impact energy, so as to avoid damage to the first distribution mechanism 3 and the cylinder 6 due to rigid impact. At the same time, the ball joint structure of the rotary joint 8 and the rotational cooperation of the connecting rod 10 ensure that the first distribution mechanism 3 swings smoothly without jamming.

[0026] With the above structure, this device can achieve precise material distribution at multiple workstations, and the buffer mechanism effectively reduces the damage to the equipment caused by material impact, thus extending the service life of the device.

[0027] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
