Description

Technical Field

[0001] This utility model relates to the field of material feeding structure technology, specifically to a multi-channel material feeding bin structure for preventing clumping. Background Technology

[0002] A hopper is a device used to store and transport powdery or granular materials, widely used in industrial production and logistics. Its main function is to convey materials to the production line or other processes through the discharge port at the bottom of the hopper. However, many materials are inherently moist, sticky, and prone to caking, easily forming clumps during storage due to environmental humidity, static electricity, or their own weight. This caking problem can cause blockages during the discharge process, leading to poor or even complete interruption of the discharge flow, thus affecting the continuity and efficiency of the production process.

[0003] Patent CN214326002U discloses a powder ore bin feeding structure, including a connector and a discharge head. The connector is connected to the discharge port of the powder ore bin. A motor is mounted on the outer circumference of the connector, and a rotating shaft is mounted on the output end of the motor, extending into the interior of the connector. Several stirring paddles are mounted on the rotating shaft. The connector also has a vertical guide groove I with an open lower end and a second guide groove II communicating with it at its upper end. The discharge head has a discharge hole that mates with the lower end of the connector, and a retaining connector that mates with the first guide groove is mounted on the inner circumference of the discharge hole. This invention prevents material blockage in the discharge head and allows for easy disassembly and cleaning of both the connector and the discharge head. The connector and discharge head are easy to assemble and disassemble.

[0004] The aforementioned existing technology uses a motor to drive a rotating shaft within the connector. When the material comes into contact with the agitator on the rotating shaft, the agitator can break up any adhering mineral powder, preventing blockage. However, this technical solution still has certain shortcomings. First, the discharge head only has one discharge hole. When the amount of material to be discharged is large, an "arching effect" can easily occur, leading to blockage of the single channel. Second, although the agitator can break up the mineral powder inside the connector, the agitator is limited to the inside of the connector and cannot completely cover the entire discharge channel structure. Some agglomerated material may not be effectively broken up, still posing a risk of blocking the discharge hole. Therefore, to address these shortcomings of the existing technology, we propose an anti-caking multi-channel discharge hopper structure, aiming to ensure smooth material discharge through multi-channel diversion and a more efficient anti-caking design. Utility Model Content

[0005] The purpose of this invention is to provide an anti-caking multi-channel feeding hopper structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-channel feeding hopper structure for preventing caking includes a rectangular feeding hopper for receiving powdery or granular materials and avoiding blockage of a single channel through multiple feeding channels at the bottom. The rear side of the rectangular feeding hopper is provided with a feeding channel for connecting to an external feeding device and conveying materials into the rectangular feeding hopper. The bottom of the rectangular feeding hopper is provided with multiple feeding channels, which reduce material accumulation and arching effect through multi-channel diversion. The output end of the feeding channel is provided with a discharge component for concentrating and guiding materials to subsequent processes.

[0008] The rectangular feeding hopper is equipped with an anti-caking component. The anti-caking component prevents material from caking or clogging through mechanical knocking and rotary conveying. The anti-caking component includes a U-shaped fixing plate that is bolted to the top cover of the rectangular feeding hopper. Multiple rotating rods are rotatably connected to the top of the inner wall of the U-shaped fixing plate. The number of rotating rods is the same as the number of feeding channels and they correspond one-to-one. The top of the rotating rod is rotatably connected to the top of the inner wall of the U-shaped fixing plate through a bearing. The rotating rod drives the knocking component and the auger to work by rotating. A double grooved wheel is provided on the outer wall of the rotating rod near the top. Two adjacent double grooved wheels are connected by a transmission belt. The double grooved wheels and the transmission belt cooperate to realize the synchronous driving of multiple rotating rods.

[0009] The top of the U-shaped fixing plate is equipped with a motor for driving one of the rotating rods to rotate. It is connected to an external power supply and controller. The motor provides rotational power for the anti-caking component. The outer wall of the rotating rod is equipped with multiple first striking elements arranged at equal intervals. The first striking elements strike the caking material in the crushing chamber by rotating. A second striking element is provided between two adjacent first striking elements. The second striking elements are staggered with the first striking elements to expand the striking coverage area.

[0010] Preferably, the discharge assembly includes a circular pipe connected to the discharge channel. The circular pipe guides the material from the discharge channel into the conical collection bin. The bottom end of the circular pipe is provided with a conical collection bin. The conical collection bin accelerates material aggregation and reduces residue through its conical structure. The bottom end of the conical collection bin is provided with a discharge pipe, which is the final output channel and the material is forcibly conveyed by an auger.

[0011] Preferably, the bottom end of the rotating rod passes through the top cover of the rectangular feeding hopper and extends into the conical collecting hopper. The rotating rod penetrates the hopper body to simultaneously drive the striking parts inside the hopper and the auger inside the discharge pipe. A sealed bearing is provided at the connection between the rotating rod and the top cover of the rectangular feeding hopper.

[0012] Preferably, the bottom end of the rotating rod is coaxially connected to an auger, the auger is located inside the discharge pipe, and the outer wall of the auger is in contact with the inner wall of the discharge pipe. The auger pushes the material to flow along the discharge pipe by rotating.

[0013] Preferably, the first striking element includes a first fixing ring bolted to the outer wall of the rotating rod. The outer wall of the first fixing ring is provided with a plurality of first round rods arranged in a ring array. The first round rods strike and crush the inner wall of the bin and the material by rotating.

[0014] Preferably, the second striking element includes a second fixing ring bolted to the outer wall of the rotating rod. The outer wall of the second fixing ring is provided with a plurality of second round rods arranged in a circular array. The second round rods are staggered from the first round rods to cover more striking areas.

[0015] Preferred, such as Figure 4 As shown, the first round rod of the first striking member and the second round rod of the second striking member are arranged in a staggered manner. The staggered arrangement design reduces the blind zone for preventing agglomeration and improves the crushing efficiency.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This anti-caking multi-channel feeding hopper structure disperses material flow pressure by setting multiple independent feeding channels, significantly reducing single-channel blockage caused by the "arch bridge effect" and ensuring continuous feeding.

[0018] 2. This anti-caking multi-channel feeding hopper structure uses a rotating rod to drive the first and second striking parts to rotate and strike the material in the hopper. Combined with the staggered arrangement of round rods, it covers a larger striking range and breaks up caking materials. At the same time, the auger and the discharge pipe are designed to be in close contact to force the material to be conveyed, avoiding residue or blockage at the discharge port.

[0027] Please see Figures 1-5 This utility model provides a technical solution:

[0028] A multi-channel feeding hopper structure for preventing caking includes a rectangular feeding hopper 100, which is used to receive powdery or granular materials and avoids blockage of a single channel through multiple feeding channels 110 at the bottom. A feeding channel 200 is provided on the rear side of the rectangular feeding hopper 100, which is used to connect to external feeding equipment and transport materials into the rectangular feeding hopper 100. Multiple feeding channels 110 are provided at the bottom of the rectangular feeding hopper 100. The feeding channels 110 reduce material accumulation and arching effect through multi-channel diversion. A discharge component 300 is provided at the output end of the feeding channel 110, which is used to concentrate and guide materials to subsequent processes.

[0029] A rectangular feeding hopper 100 is equipped with an anti-caking component 400. The anti-caking component 400 prevents materials from caking or clogging through mechanical knocking and rotary conveying. The anti-caking component 400 includes a U-shaped fixing plate 410 that is bolted to the top cover of the rectangular feeding hopper 100. Multiple rotating rods 420 are rotatably connected to the top of the inner wall of the U-shaped fixing plate 410. The number of rotating rods 420 is the same as the number of feeding channels 110 and they correspond one-to-one. The top of the rotating rod 420 is rotatably connected to the top of the inner wall of the U-shaped fixing plate 410 through a bearing. The rotating rod 420 drives the knocking component and the auger 480 to work through rotation. A double grooved wheel 430 is provided on the outer wall of the rotating rod 420 near the top. Two adjacent double grooved wheels 430 are connected by a transmission belt 440. The double grooved wheels 430 and the transmission belt 440 cooperate to realize the synchronous drive of multiple rotating rods 420.

[0030] The top of the U-shaped fixing plate 410 is equipped with a motor 450 for driving one of the rotating rods 420 to rotate. It is connected to an external power supply and controller. The motor 450 provides rotational power for the anti-caking assembly 400. The outer wall of the rotating rod 420 is provided with a plurality of first striking elements 460 arranged vertically at equal intervals. The first striking elements 460 strike the agglomerated material in the crushing chamber by rotating. A second striking element 470 is provided between two adjacent first striking elements 460. The second striking elements 470 are staggered with the first striking elements 460 to expand the striking coverage area.

[0031] In this embodiment, the discharge assembly 300 includes a circular pipe 310 connected to the discharge channel 110. The circular pipe 310 is used to guide the material from the discharge channel 110 into the conical collection bin 320. The bottom end of the circular pipe 310 is provided with the conical collection bin 320. The conical collection bin 320 accelerates material aggregation and reduces residue through its conical structure. The bottom end of the conical collection bin 320 is provided with a discharge pipe 330, which is the final output channel and is forcibly conveyed by the auger 480.

[0032] Specifically, the bottom end of the rotating rod 420 passes through the top cover of the rectangular feeding hopper 100 and extends into the conical collecting hopper 320. The rotating rod 420 passes through the hopper body to simultaneously drive the striking parts inside the hopper and the auger 480 inside the discharge pipe 330. A sealed bearing 490 is provided at the connection between the rotating rod 420 and the top cover of the rectangular feeding hopper 100.

[0033] Furthermore, the bottom end of the rotating rod 420 is coaxially connected to an auger 480, which is located inside the discharge pipe 330. The outer wall of the auger 480 is in contact with the inner wall of the discharge pipe 330. The auger 480 pushes the material to flow along the discharge pipe 330 by rotating.

[0034] Furthermore, the first striking element 460 includes a first fixing ring 461 bolted to the outer wall of the rotating rod 420.

[0036] Furthermore, such as Figure 4 As shown, the first round rod 462 of the first striking member 460 and the second round rod 472 of the second striking member 470 are arranged in a staggered manner. The staggered arrangement design reduces the blind zone for preventing agglomeration and improves the crushing efficiency.

[0037] In this embodiment, the anti-caking multi-channel feeding hopper structure allows material to enter the rectangular feeding hopper 100 through the feeding channel 200 and be stored inside. Multiple feeding channels 110 at the bottom of the rectangular feeding hopper 100 reduce material accumulation through multi-channel diversion. Material then enters the circular pipe 310 of the discharge assembly 300 through the feeding channels 110. The circular pipe 310 transports the material to the conical collecting hopper 320. The conical collecting hopper 320 accelerates material aggregation and reduces residue through its conical structure. Finally, the material is output through the discharge pipe 330. During this process, the motor 45 of the anti-caking assembly 400... Upon startup, one of the rotating rods 420 is driven to rotate. The rotating rod 420 drives the other rotating rods 420 to rotate synchronously via a double grooved wheel 430 and a transmission belt 440. The first striking element 460 and the second striking element 470 on the rotating rod 420 strike the material in the bin as it rotates. The first round rod 462 of the first striking element 460 and the second round rod 472 of the second striking element 470 are staggered to cover a larger striking range and break up agglomerated materials. At the same time, the auger 480 at the bottom of the rotating rod 420 rotates in the discharge pipe 330, pushing the material to flow along the discharge pipe 330 and avoiding blockage.
