Description

Technical Field

[0001] This utility model relates to the field of hopper arch breaking technology, specifically a hopper arch breaking device for bulk cargo operations. Background Technology

[0002] In modern industry, hoppers are widely used as key equipment for storing and transferring bulk materials in bulk cargo operations such as mining, port loading and unloading, and grain storage and transportation. During the unloading process, due to factors such as the friction and cohesion between the bulk materials themselves, as well as the adhesion to the inner wall of the hopper, bulk materials are prone to forming an arched structure above the hopper outlet, a phenomenon known as "material arching." Once formed, material arching severely hinders the smooth discharge of materials, leading to poor or even interrupted discharge, greatly reducing the efficiency of bulk cargo operations and increasing operating costs.

[0003] Most existing arch-breaking devices adopt a single arch-breaking method, such as vibration, stirring, or simple pushing to break the material arch. A single arch-breaking method often has many limitations in practical applications. When relying solely on pushing to break the arch, it may not be able to penetrate deep into the internal structure of the material arch, resulting in poor arch-breaking effect and easy reformation of the material arch. On the other hand, simply using stirring and crushing to break the arch may not be able to quickly and effectively break the already formed stable material arch, and may not be able to transport the crushed material out in time during the crushing process, causing the material to accumulate again in the hopper. Therefore, this utility model provides an arch-breaking device for bulk cargo hoppers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bulk cargo handling hopper arch-breaking device. This solves the problem that most existing arch-breaking devices use a single arch-breaking method, such as vibration, stirring, or simple pushing, to break the material arch. A single arch-breaking method often has many limitations in practical applications. When relying solely on pushing to break the arch, it may not be able to penetrate deep into the internal structure of the material arch, resulting in poor arch-breaking effect and easy reformation of the material arch. On the other hand, simply using stirring and crushing methods to break the arch may not be able to quickly and effectively break the already formed stable material arch, and may not be able to transport the crushed material out in time during the crushing process, causing the material to accumulate again in the hopper.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bulk cargo handling hopper arch-breaking device, comprising a hopper body, wherein the hopper body is provided with an arch-breaking mechanism for discharging bulk cargo from the hopper, the arch-breaking mechanism comprising:

[0006] The jacking assembly includes a chute extending through the lower side wall of the hopper body. A fixed rod connected to the inner wall of the chute via a lifting assembly is provided. A jacking rod is fixed to the upper end of the fixed rod. An arch-breaking cone block is fixed to the top of the jacking rod. An arch-breaking cone rod is fixed to the outer wall of the arch-breaking cone block.

[0007] The conveying assembly includes a connecting shaft connected to the inner wall of the upper end of the hopper body via a drive assembly. A crushing rod is fixed to the lower end of the connecting shaft, a connecting ring is fixed to the lower end of the crushing rod, and a spiral shaft that fits against the inner wall of the hopper body is fixed to the lower end of the connecting ring. Push plates for pushing materials are uniformly fixed to the surface of the spiral shaft.

[0008] Preferably, the lifting assembly includes a pair of fixed brackets fixed to the lower outer wall of the hopper body, a hydraulic rod fixed inside the fixed brackets, a sliding frame fixed to the output end of the hydraulic rod, and the fixed rod extending to the outside of the chute and fixedly connected to the sliding frame.

[0012] Preferably, four sets of crushing rods are provided along the lower outer wall of the connecting shaft, and the four sets of crushing rods are in an L-shaped structure.

[0013] Beneficial effects

[0014] This utility model provides a device for breaking up arches in bulk cargo hoppers. Compared with the prior art, it has the following advantages:

[0015] Firstly, this utility model uses a top-pushing component to insert the arch-breaking cone block and arch-breaking cone rod into the material arch from below the hopper body. In conjunction with the crushing rod in the conveying component, it mixes and crushes from above, achieving coordinated arch breaking from both above and below. Compared with a single arch-breaking method, it can destroy the material arch structure more quickly and effectively, greatly improving the arch-breaking efficiency, ensuring the continuity of bulk cargo operations, effectively breaking the bridging phenomenon between bulk cargo, solving the problem of difficulty in unloading bulk cargo in the hopper, and improving unloading efficiency.

[0016] Secondly, this utility model has four sets of L-shaped crushing rods fixed at the lower end of the connecting shaft. The crushing rods rotate with the rotation of the connecting shaft to crush the bulk materials in the hopper body, preventing large pieces of bulk materials from clogging the discharge port. When the screw shaft and push plate in the conveying component rotate, they can not only further crush the material arch, but also push the material downward to convey the material and prevent the material from clogging in the hopper. This allows the material to be discharged evenly and stably from the discharge port of the hopper body, improving the efficiency and quality of bulk material handling. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a bulk cargo handling hopper arch-breaking device, including a hopper body 1, and an arch-breaking mechanism for discharging bulk cargo from the hopper body 1, the arch-breaking mechanism including:

[0024] The push assembly includes a chute 2 through the lower side wall of the hopper body 1. A fixed rod 201 connected by a lifting assembly is provided on the inner wall of the chute 2. A push rod 3 is fixed at the upper end of the fixed rod 201. An arch-breaking cone block 301 is fixed at the top of the push rod 3. An arch-breaking cone rod 302 is fixed on the outer wall of the arch-breaking cone block 301.

[0025] The conveying assembly includes a connecting shaft 403 connected to the inner wall of the upper end of the hopper body 1 via a drive assembly. A crushing rod 5 is fixed to the lower end of the connecting shaft 403. A connecting ring 501 is fixed to the lower end of the crushing rod 5. A spiral shaft 502 that fits against the inner wall of the hopper body 1 is fixed to the lower end of the connecting ring 501. A pusher plate 503 for pushing materials is uniformly fixed to the surface of the spiral shaft 502.

[0026] In a preferred embodiment, the lifting assembly includes a pair of fixed brackets 202 fixed to the lower outer wall of the hopper body 1. A hydraulic rod 203 is fixed inside the fixed bracket 202. A sliding frame 204 is fixed to the output end of the hydraulic rod 203. The fixed rod 201 extends to the outside of the slide groove 2 and is fixedly connected to the sliding frame 204. Positioning rods 205 are fixed to the upper and lower four ends of the fixed bracket 202. The sliding frame 204 is slidably connected to the positioning rods 205. The arch-breaking cone rods 302 are set in four groups. The four groups of arch-breaking cone rods 302 are evenly inclined downward along the outer wall of the arch-breaking cone block 301.

[0027] When material accumulates and forms an arch within the hopper body 1, obstructing the discharge of bulk materials, the arch-breaking device is activated. This activates the hydraulic rod 203 on the fixed support 202. The output end of the hydraulic rod 203 pushes the sliding frame 204 to slide upward along the positioning rod 205. Since the fixed rod 201 extends to the outside of the chute 2 and is fixedly connected to the sliding frame 204, the upward movement of the sliding frame 204 causes the fixed rod 201 to rise, which in turn causes the push rod 3 to push the arch-breaking cone block 301 and the arch-breaking cone rod 302 upward. The arch-breaking cone block 301 and the downward-sloping arch-breaking cone rod 302 insert into the material arch, breaking the arch from below, loosening the material, breaking the bridging phenomenon between bulk materials, and allowing the bulk materials to fall smoothly.

[0028] In the lifting assembly, the sliding frame 204 is slidably connected to the positioning rod 205, providing a stable guide for the lifting of the jacking assembly.

[0029] The jacking assembly inserts the arch-breaking cone block 301 and the arch-breaking cone rod 302 into the material arch from below the hopper body 1. Together with the crushing rod 5 in the conveying assembly, they are stirred and crushed from above, achieving coordinated arch breaking from both above and below. Compared with a single arch breaking method, this method can destroy the material arch structure more quickly and effectively, greatly improving the arch breaking efficiency, ensuring the continuity of bulk cargo operations, effectively breaking the bridging phenomenon between bulk cargo, solving the problem of difficulty in unloading bulk cargo in the hopper, and improving unloading efficiency.

[0030] In a preferred embodiment, the drive assembly includes a mounting housing 4 fixed to the upper end of the hopper body 1. A drive rod 401 is rotatably connected through the mounting housing 4 in the horizontal direction. A first bevel gear 402 is fixed to one end of the drive rod 401. A connecting shaft 403 is rotatably connected through the mounting housing 4 in the vertical direction. A second bevel gear 404 is fixed to one end of the connecting shaft 403 near the first bevel gear 402 inside the mounting housing 4. The first bevel gear 402 and the second bevel gear 404 are meshed together. Four sets of crushing rods 5 are arranged along the lower outer wall of the connecting shaft 403, and the four sets of crushing rods 5 are in an L-shaped structure.

[0031] The drive rod 401 inside the housing 4 is driven by an external motor to rotate. The drive rod 401 drives the first bevel gear 402 to rotate. Since the first bevel gear 402 is meshed with the second bevel gear 404, the rotation of the first bevel gear 402 drives the second bevel gear 404 to rotate through the meshing relationship, which in turn causes the connecting shaft 403 to rotate. The rotation of the connecting shaft 403 drives the lower crushing rod 5, connecting ring 501, spiral shaft 502 and push plate 503 to rotate together. During the rotation, the four sets of L-shaped crushing rods 5 stir and crush the material in the upper part of the hopper body 1. The spiral shaft 502 is in contact with the inner wall of the hopper body 1. The push plate 503 on the surface pushes the material downward when it rotates, helping the material to pass smoothly through the discharge port, and at the same time further destroying any remaining material arch structure.

[0032] Four sets of L-shaped crushing rods 5 are fixed to the lower end of the connecting shaft 403. The crushing rods 5 rotate with the rotation of the connecting shaft 403 to crush the bulk materials in the hopper body 1, preventing large pieces of bulk materials from clogging the discharge port. When the screw shaft 502 and push plate 503 in the conveying assembly rotate, they can not only further crush the material arch, but also push the material downward to convey the material, prevent the material from clogging in the hopper, and enable the material to be discharged evenly and stably from the discharge port of the hopper body 1, thereby improving the efficiency and quality of bulk material handling.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, when material accumulates in the main body 1 of the hopper and forms an arch that obstructs the discharge of bulk materials, the arch-breaking device is activated. First, the hydraulic rod 203 on the fixed support 202 is activated, and its output end pushes the sliding frame 204 to slide upward along the positioning rod 205. Since the fixed rod 201 is fixedly connected to the sliding frame 204, the upward movement of the sliding frame 204 causes the fixed rod 201 to rise, which in turn causes the push rod 3 to push the arch-breaking cone block 301 and the arch-breaking cone rod 302 to move upward. The arch-breaking cone block 301 and the downwardly tilted arch-breaking cone rod 302 insert into the material arch and break the material arch from below, loosening the material and breaking the bridging phenomenon between bulk materials.

[0035] Meanwhile, the drive rod 401 inside the housing 4 is driven by an external motor to rotate. The drive rod 401 drives the first bevel gear 402 to rotate. The meshing relationship between the first bevel gear 402 and the second bevel gear 404 causes the second bevel gear 404 to rotate, which in turn drives the connecting shaft 403 to rotate. The connecting shaft 403 then drives the lower crushing rod 5, connecting ring 501, spiral shaft 502 and push plate 503 to rotate together. The four sets of L-shaped crushing rods 5 stir and crush the material in the upper part of the hopper body 1. When the push plate 503 on the surface of the spiral shaft 502 rotates, it pushes the material downward, assisting the material to pass smoothly through the discharge port, further destroying the residual material arch structure, preventing large pieces of loose material from blocking the discharge port, and enabling the material to be discharged evenly and stably from the discharge port of the hopper body 1. When the material arch is completely destroyed and the material is discharged smoothly, the hydraulic rod 203 retracts and drives the push assembly to descend and reset, stopping the drive rod 401 from rotating and stopping the conveying assembly from working.
