Description

Technical Field

[0001] This utility model relates to the technical field of air chute conveyors, and in particular to an air chute conveyor that facilitates material unloading. Background Technology

[0002] In industrial production, the conveying of powdery and granular materials is a core production process in many industries, such as cement manufacturing, chemical raw material processing, and grain storage and transportation. As a widely used and efficient conveying equipment, the air chute conveyor, with its simple structure, low energy consumption, and excellent sealing performance, fluidizes materials by compressing air and uses the combined effect of gravity and airflow to propel the materials along the chute, achieving stable and reliable continuous conveying.

[0003] However, in practical applications, the complexity and diversity of material properties pose significant challenges to the conveying process. Powdered and granular materials from different industries exhibit significant differences in their physicochemical properties: for highly viscous materials, strong intermolecular forces easily lead to particle adhesion and agglomeration, disrupting the uniformity of fluidized bed conveying; when handling high-humidity materials, the water film formed on the particle surface not only enhances inter-particle adhesion but may also trigger changes in the material's composition and properties. Furthermore, when conveying materials with uneven particle size distribution, the effect of airflow on particles of different sizes varies significantly—small particles are easily carried by the airflow, while large particles settle rapidly due to gravity. This dynamic difference causes material stratification within the chute, ultimately leading to localized accumulation at the discharge port, thereby reducing material discharge efficiency and affecting normal production.

[0004] In summary, existing air chute conveyors suffer from the problem of material accumulation at the discharge port. Utility Model Content

[0007] The impact vibration mechanism includes a fixed frame, a rotating shaft, a U-shaped crankshaft, a motor, a crank, a hinge frame, and a moving bar. The fixed frame includes a first support plate and second support plates located at the left and right ends of the first support plate. Two rotating shafts are arranged opposite each other and are respectively located on the two second support plates. The two ends of the U-shaped crankshaft are located between the two rotating shafts. One end of the crank is rotatably mounted on the U-shaped crankshaft, and the other end of the crank is rotatably mounted on the hinge frame. The end of the hinge frame away from the crank is connected to the moving bar.

[0011] The motor is mounted on a second mounting plate, which has an output hole. The motor output end is provided with a drive shaft, which is located inside the output hole.

[0012] The end of the drive shaft furthest from the motor output is connected to one of the rotating shafts.

[0013] Furthermore, the second support plate has a rotating hole that mates with the rotating shaft, and the rotating shaft is located in the rotating hole.

[0014] Furthermore, the zigzag crankshaft includes a first connecting shaft, a second connecting shaft, and a third connecting shaft. There are two second connecting shafts, which are respectively located at both ends of the first connecting shaft. There are two third connecting shafts, which are perpendicular to the two second connecting shafts.

[0015] The two rotating shafts are respectively connected to the two connecting shafts;

[0016] The front end of the crank is rotatably mounted on the connecting shaft.

[0017] Furthermore, the crank includes a crank body and a connecting ring, the front end of the crank body is fixedly connected to the connecting ring, and the connecting ring is fitted onto the outside of the connecting shaft.

[0018] Furthermore, a connecting block is provided at the end of the moving bar away from the hinge frame.

[0019] Furthermore, a striking block is provided at the end of the connecting block away from the moving strip.

[0020] Furthermore, the connecting block is made of an elastic material.

[0021] Furthermore, the impact vibration mechanism is also equipped with a rebound mechanism;

[0022] The rebound mechanism includes a first fixed plate, a second fixed plate, and a guide rod;

[0023] There are two second fixing plates, which are respectively located at the left and right ends of the moving bar. There are two guide rods, which are respectively located on the front side of the two second fixing plates.

A motor drives a rotating shaft, which in turn rotates a U-shaped crankshaft. A crank connected to the U-shaped crankshaft drives a hinged frame and a moving bar in reciprocating motion. During operation, the moving bar periodically strikes the outer wall of the air chute, and the resulting vibration effectively prevents material from accumulating and clogging near the outlet. For some highly viscous or less fluid powdery or granular materials, this vibration can break down the agglomeration structure, promoting faster discharge from the outlet, greatly improving discharge efficiency and ensuring smooth production processes.

[0039] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0040] like Figures 1 to 5 As shown, this utility model provides an air chute conveyor that facilitates material unloading, including a conveyor body 1, an air chute 2 connected to the bottom of the material unloading port of the conveyor body 1, a striking vibration mechanism 3 provided at one end of the air chute 2 away from the material unloading port of the conveyor body 1, and a striking vibration mechanism 3 provided at one end of the air chute 2 near the material unloading port of the air chute 2.

[0041] The impact vibration mechanism 3 includes a fixed frame 31, a rotating shaft 32, a U-shaped crankshaft 33, a motor 35, a crank 36, a hinge frame 37, and a moving bar 38. The fixed frame 31 includes a first support plate 6 and second support plates 7 located at the left and right ends of the first support plate 6. Two rotating shafts 32 are arranged opposite each other and are respectively located on the two second support plates 7. The two ends of the U-shaped crankshaft 33 are located between the two rotating shafts 32. One end of the crank 36 is rotatably located on the U-shaped crankshaft 33, and the other end of the crank 36 is rotatably located on the hinge frame 37. The end of the hinge frame 37 away from the crank 36 is connected to the moving bar 38.

[0042] Motor 35 is used to drive one of the rotating shafts 32 to rotate;

[0043] This easy-to-discharge air chute conveyor is made by setting an air chute 2 at the bottom of the discharge port of the conveyor body 1. The air chute 2 is connected to the discharge port of the conveyor body 1, so that the material can fall into the air chute 2 through the discharge port of the conveyor body 1.

[0044] A striking vibration mechanism 3 is provided at one end of the air chute 2 near the outlet of the air chute 2. Specifically, the striking vibration mechanism 3 is used to strike the outlet of the air chute 2 by striking vibration, which can break the agglomeration structure between materials and make the materials discharge from the outlet more quickly.

[0045] The fixing frame 31 is U-shaped. Specifically, the fixing frame 31 includes a first support plate 6 and two second support plates 7. The two second support plates 7 are respectively installed at the left and right ends of the first support plate 6, and both second support plates 7 are perpendicular to the first support plate 6, forming a U-shape. The rear ends of both second support plates 7 are fixedly installed on the air inclined groove 2.

[0046] Two rotating shafts 32 are arranged opposite to each other, and the two rotating shafts 32 rotate on two second support plates 7 respectively; while the zig-shaped crankshaft 33 is zig-shaped in general, and the two ends of the zig-shaped crankshaft 33 are respectively installed on the two rotating shafts 32.

[0047] One end of the crank 36 is rotatably mounted on the U-shaped crankshaft 33. Specifically, one end of the crank 36 is rotatably mounted on the side of the U-shaped crankshaft 33 away from the rotating shaft 32, and the other end of the crank 36 is rotatably mounted on the hinge frame 37. The end of the hinge frame 37 away from the crank 36 is connected to the moving bar 38.

[0048] Motor 35 is used to drive one of the rotating shafts 32 to rotate;

[0049] The operation procedure of the impact vibration mechanism 3 is as follows:

[0050] When the motor 35 is started, its output drives one of the rotating shafts 32 to rotate. Since the two rotating shafts 32 are fixedly connected to a U-shaped crankshaft 33 at one end within the fixed frame 31, the rotation of the rotating shaft 32 will synchronously drive the crankshaft 33 to rotate around the central axis of the rotating shaft 32. Since the rear end of the crank 36 is rotatably provided with a hinge frame 37, the circular motion of the front end of the crank 36 is converted into the linear motion of the hinge frame 37. The moving bar 38 fixedly connected to the rear end of the hinge frame 37 will follow the hinge frame 37 to make a linear motion. The moving bar 38 rotates periodically, and thus periodically hits the outer wall of the air chute 2. The resulting vibration can effectively prevent the material from accumulating and clogging near the outlet of the air chute 2.

[0051] In the operation of the impact vibration mechanism 3, the rotational power output by the motor 35 is transmitted to the U-shaped crankshaft 33 through the rotating shaft 32, completing the initial power transmission. The crank 36, which is rotatably connected to the surface of the U-shaped crankshaft 33, will make circular motion with the rotation of the crankshaft 33 when the U-shaped crankshaft 33 rotates.

[0052] Based on this easy-to-discharge air chute conveyor, the impact vibration mechanism 3 enables periodic impact at the outlet of the air chute 2, actively disrupting the initial accumulation of materials at the outlet and effectively preventing blockages caused by material adhesion, moisture absorption, or particle size differences. This mechanism significantly reduces the frequency of manual cleaning, avoids downtime for maintenance due to blockages, and thus improves the continuous operation efficiency and stability of the production line.

[0053] For materials with high viscosity, high humidity, or uneven particle size, the physical impact of this impact vibration mechanism 3 can directly overcome the adhesion between particles or the tension of the water film, forcibly separating the adhering material clumps. Compared with traditional methods that rely solely on airflow control, this impact vibration mechanism 3 is more adaptable to the physicochemical properties of materials, and can significantly broaden the application scenarios of air chute conveyors.

[0054] The impact vibration mechanism 3 does not require complex modifications to the existing conveyor body 1, and it is easy to maintain, with controllable energy consumption, achieving efficient anti-blocking under low energy consumption.

[0055] Furthermore, blockages can cause localized pressure or moisture in the material retention area, potentially leading to hardening, caking, or even chemical reactions (such as cement caking or grain mold). The immediate unblocking function of the impact vibration mechanism 3 can avoid such risks, while also reducing the potential for dust exposure or mechanical damage during manual cleaning, thus meeting safety and environmental protection requirements.

[0056] like Figures 1 to 5As shown, in some embodiments of this utility model, a rotary level switch 5 is also provided at one end of the air chute 2 near the outlet of the air chute 2, and the impact vibration mechanism 3 is located above the rotary level switch 5.

[0057] Because the material may not be able to be observed in time if it reaches the discharge port of the air chute 2 during the material feeding process, a rotary level switch 5 is installed. The rotary level switch 5 includes a mounting plate, a sensor and an alarm. The mounting plate is located on top of the sensor and both the mounting plate and the sensor are located inside the air chute 2. The alarm is located outside the air chute 2.

[0058] Specifically, the working process of the rotary paddle level switch 5 is as follows:

[0059] When the material is at the unloading position, the rotary level switch 5 starts normally and the sensor does not detect that there is material accumulation below. When the material reaches the loading position, the material contacts the sensor under the mounting plate, the alarm sounds, and then the impact vibration mechanism 3 can be started to knock and clean it. At the same time, it can promptly prompt the operator to intervene.

[0060] The rotary paddle level switch 5 can monitor the material height in real time, ensuring normal equipment startup during the unloading stage and avoiding idling or unnecessary energy consumption. When the material reaches the loading stage, an alarm is triggered to promptly alert the operator and prevent material overflow or excessive accumulation. Combined with the anti-blocking function of the impact vibration mechanism 3, a dual protection mechanism of "material level warning + active unblocking" is formed, significantly improving the stability and safety of the conveying system.

[0061] like Figures 1 to 5 As shown, in some embodiments of this utility model, the fixing frame 31 is provided with an L plate 34, which includes a mounting plate 341 and a mounting plate 342.

[0062] One end of mounting plate 341 is mounted on the fixing frame 31, and the other end of mounting plate 341 is perpendicular to mounting plate 342.

[0063] The mounting end of the motor 35 is located on the mounting plate 342. The mounting plate 342 has an output hole. The output end of the motor 35 is provided with a drive shaft 351, which is located inside the output hole.

[0064] One end of the drive shaft 351 away from the output end of the motor 35 is connected to one of the rotating shafts 32;

[0065] Specifically, the mounting plate 341 is fixedly mounted on the second support plate 7 located at the right end of the first support plate 6; the second support plate 7 has a rotating hole 71 that mates with the rotating shaft 32, and the rotating shaft 32 is located in the rotating hole 71.

[0066] Mark the second support plate 7 located at the right end of the first support plate 6 as support plate #1, mark the second support plate 7 located at the left end of the first support plate 6 as support plate #2, mark the rotating shaft 32 installed on support plate #1 as rotating shaft #1, and mark the rotating shaft 32 installed on support plate #2 as rotating shaft #2.

[0067] The output end of motor 35 is connected to drive shaft 351. Drive shaft 351 is located inside the output hole, and one end of drive shaft 351 that passes through the output hole is connected to shaft #1.

[0068] Based on the above settings, the main operating process in actual operation is as follows:

[0069] When the motor 35 starts, it drives the drive shaft 351 to rotate, which in turn drives the 1# rotating shaft connected to the drive shaft 351 to rotate. Since there is a U-shaped crankshaft 33 between the 1# and 2# rotating shafts, that is, the two ends of the U-shaped crankshaft 33 are respectively installed to the 1# and 2# rotating shafts, the rotation of the 1# rotating shaft will drive the rotation of the U-shaped crankshaft 33.

[0070] like Figures 1 to 5 As shown, in some embodiments of this utility model, the U-shaped crankshaft 33 includes a first connecting shaft 331, a second connecting shaft 332, and a third connecting shaft 333. There are two second connecting shafts 332, which are respectively located at both ends of the first connecting shaft 331. There are two third connecting shafts 333, which are perpendicular to the two second connecting shafts 332.

[0071] The two rotating shafts 32 are respectively connected to the two connecting shafts 333;

[0072] Specifically, the zigzag crankshaft 33 includes a first connecting shaft 331, a second connecting shaft 332, and a third connecting shaft 333. There are two second connecting shafts 332, which are respectively located at both ends of the first connecting shaft 331. There are two third connecting shafts 333, which are perpendicular to the two second connecting shafts 332. The first connecting shaft 331, the two second connecting shafts 332, and the two third connecting shafts 333 form a zigzag structure. The two ends of the zigzag crankshaft 33 are respectively fixedly connected to two rotating shafts 32.

[0073] The front end of the crank 36 is rotatably mounted on the connecting shaft 331. Specifically, the crank 36 includes a crank body 361 and a connecting ring 362. The front end of the crank body 361 is fixedly connected to the connecting ring 362. The connecting ring 362 is fitted onto the outside of the connecting shaft 331, that is, the connecting shaft 331 is rotatably mounted inside the connecting ring 362.

[0074] With this configuration, when the motor 35 starts, it drives the drive shaft 351 to rotate, which in turn drives the rotating shaft 32 connected to the drive shaft 351 to rotate. The rotating shaft 32 drives the U-shaped crankshaft 33 to rotate, that is, the connecting shaft 331 on the U-shaped crankshaft 33 can rotate around the axis of the rotating shaft 32. Since the connecting ring 362 is fitted outside the connecting shaft 331, the U-shaped crankshaft 33 rotates, driving the front end of the crank body 361 to rotate.

[0075] like Figures 1 to 5 As shown, in some embodiments of this utility model, a connecting block 39 is fixedly installed on the end of the movable bar 38 away from the hinge frame 37; the connecting block 39 is made of an elastic material.

[0076] A striking block 311 is fixedly installed on the end of the connecting block 39 away from the moving bar 38;

[0077] The connecting block 39 and the striking block 311 are fixedly connected sequentially at the rear end of the moving bar 38. When the moving bar 38 moves back and forth in a straight line, the striking block 311 will periodically impact the outer wall of the front of the air chute 2 near the discharge port. The presence of the connecting block 39 plays a buffering and protective role, preventing the striking block 311 from directly impacting the air chute 2 and causing damage, while also allowing the impact force to be transmitted to the air chute 2 more gently.

[0078] like Figures 1 to 5 As shown, in some embodiments of this utility model, a protective pad is provided at one end of the striking block 311 away from the connecting block 39; the protective pad is detachably disposed on the striking block 311, specifically, the detachable connection method can be an adhesive connection method or a screw connection method.

[0079] like Figures 1 to 5 As shown, in some embodiments of this utility model, the striking vibration mechanism 3 is further provided with a rebound mechanism 4.

[0080] The springback mechanism 4 includes a first fixed plate 312, a second fixed plate 41, and a guide rod 42;

[0081] Two second fixing plates 41 are provided, and the two second fixing plates 41 are respectively provided at the left end and the right end of the moving bar 38. Two guide rods 42 are provided, and the two guide rods 42 are respectively provided on the front side of the two second fixing plates 41.

[0082] The first fixing plate 312 is disposed between the two second support plates 7, and the first fixing plate 312 is located in front of the second fixing plate 41;

[0083] The first fixing plate 312 has a through hole that matches the guide rod 42. The end of the guide rod 42 that passes through the through hole is provided with a limiting plate 43, that is, the front end of the guide rod 42 passes through the through hole and is fixedly provided with the limiting plate 43.

[0084] A spring 44 is fitted on the outside of the guide rod 42, and the two ends of the spring 44 are respectively connected to the limiting plate 43 and the first fixing plate 312;

[0085] The front side of the first fixed plate 312 is provided with a sliding groove 313 that cooperates with the moving strip 38;

[0086] Specifically, the groove 313 on the front of the first fixed plate 312 that matches the moving bar 38 plays a limiting role for the moving bar 38, ensuring that it can only move in the front and back direction, thereby ensuring the stability and accuracy of the entire movement.

[0087] As the motor 35 continues to operate, the striking block 311 repeatedly strikes, causing vibration on the outer wall of the air chute 2. When the striking block 311 impacts the outer wall of the air chute 2, the moving bar 38 and the connected second fixed plate 41 are subjected to an impact force. At this time, the guide rod 42 fixed to the front of the second fixed plate 41 will slide backward along the through holes matching the guide rod 42 opened at the left and right ends of the front side of the first fixed plate 312 under the action of this impact force.

[0088] As the guide rod 42 slides backward, the spring 44, which is fitted between the first fixed plate 312 and the limiting plate 43 on the surface of the guide rod 42, is compressed. The spring 44 stores elastic potential energy. After the striking block 311 completes one striking action, the spring 44 begins to release the stored elastic potential energy. The front end of the spring 44 is fixedly connected to the rear end of the limiting plate 43, and the rear end of the spring 44 is fixedly connected to the front end of the first fixed plate 312. Under the action of elastic potential energy, the spring 44 pushes the guide rod 42 to slide forward, thereby causing the second fixed plate 41, the moving bar 38, and the striking block 311 to quickly rebound and reset, returning to their initial positions, preparing for the next striking action. The existence of the rebound mechanism 4 not only enables the striking vibration mechanism 3 to quickly reset and increase the striking frequency, but also buffers the impact force during the striking process, protecting the equipment components from damage.

[0089] In this invention, the vibration generated by the impact vibration mechanism 3 works synergistically with the flow of material within the air chute 2. The vibration continuously alters the contact state between material particles, further enhancing the fluidization effect. For materials with high viscosity or poor flowability, the vibration can disrupt the agglomeration structure, making the material flow more easily. Under the combined action of gravity, airflow, and vibration, the material slides along the inclined direction of the air chute 2 towards the discharge port, ultimately being discharged from the discharge port, achieving a highly efficient material feeding and conveying process.

[0090] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
