Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor, specifically to a feeding hopper suitable for conveying cohesive loess by belt. Background Technology

[0002] Existing belt conveyor systems are mostly used in industrial fields such as mining and metallurgical smelting. As a key piece of equipment connecting material storage and belt conveying systems, the belt feed hopper plays an important role in buffering material flow and stabilizing the feeding rhythm. The materials used in mining and metallurgical smelting are mostly ores, sand, gravel, coal powder, etc., which have low viscosity and good flowability, allowing the materials to slide smoothly down the inner wall of the feed hopper to the discharge port.

[0003] In practical applications, the existing technology for feeding hoppers has a relatively complete structure and function, which can basically meet daily usage needs. However, the following problems still exist:

[0004] When using a belt conveyor to transport highly viscous loess, the loess is sticky and absorbent. As the moisture content increases, its viscosity and angle of repose also increase. The material tends to accumulate and adhere to the inner wall of the feeding hopper, causing the belt conveyor to malfunction and not operate continuously. Furthermore, cleaning the material that has accumulated and adhered to the inner wall of the feeding hopper is difficult and poses a high risk.

[0005] Therefore, this utility model provides a feeding hopper suitable for conveying cohesive loess by belt. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a feeding hopper suitable for conveying cohesive loess by belt.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a feeding hopper suitable for conveyor belt transport of cohesive loess, comprising a hopper body,

[0008] The chamber is lined with polytetrafluoroethylene (PTFE) sheets.

[0009] A support frame is installed on the chamber body, and a vibration motor is installed on the support frame;

[0010] The support is equipped with a feeding and stirring structure;

[0011] The feeding agitation structure includes a feeding screen cylinder, a support block installed on the top of the silo, and a drive motor installed on the bracket. A slip ring is welded to the outside of the feeding screen cylinder, and the support block is slidably connected to the slip ring. A toothed ring is welded to the outside of the feeding screen cylinder. A shaft is installed at the output end of the drive motor, and a gear is installed at the top of the shaft. The gear and the toothed ring are meshed. A T-shaped rod is installed inside the feeding screen cylinder, and an agitator is installed on the T-shaped rod. The agitator is located inside the silo.

[0012] By utilizing the excellent self-lubricating properties of PTFE sheets, the ability of sticky loess to adhere to the walls is reduced. In addition, by starting the vibration motor and driving the motor, the T-shaped rod rotates, which in turn drives multiple agitator rods to rotate, thereby achieving the effect of agitating the sticky loess inside the silo and helping to prevent the sticky loess from clogging inside the silo.

[0013] In a preferred embodiment, a screen is installed inside the feed screen cylinder, and the T-shaped rod is located below the screen.

[0014] The technical effect of adopting the above-mentioned further solution is that, through the presence of the screen and in conjunction with the vibrating motor, the screen vibrates, and the cohesive loess falls onto the vibrating screen for vibration treatment in advance, which can pre-disperse the cohesive loess and help reduce the subsequent accumulation and blockage of the cohesive loess.

[0015] In a preferred embodiment, the feed inlet of the feed screen cylinder is equipped with a feed hopper.

[0016] The technical effect of adopting the above-mentioned further solution is that the presence of the feed hopper increases the feed opening, making it easier for the excavator to load materials.

[0017] In a preferred embodiment, the support includes a force-bearing plate, and a vibration spring is installed at the bottom of the force-bearing plate.

[0018] The technical effect of adopting the above-mentioned further solution is that the presence of the vibration spring enhances the amplitude brought about by the vibration motor.

[0019] In a preferred embodiment, a support leg is mounted on the bottom end of the vibration spring, and a connecting plate is mounted on the support leg;

[0020] The connecting plate is equipped with a fixing component.

[0021] The technical effect of adopting the above-mentioned further solution is that by setting out legs and connecting plates, the device can be supported as a whole.

[0022] In a preferred embodiment, the fixing assembly includes a base block mounted on a connecting plate, a hydraulic rod mounted on the base block, a pressing plate mounted on the telescopic end of the hydraulic rod, and the pressing plate being located above the force-bearing plate.

[0023] The technical effect of adopting the above-mentioned further solution is that by setting a fixed component and activating the hydraulic rod, its telescopic end drives the extrusion plate to move down and extrude the force plate, thereby compressing the vibration spring and achieving the effect of stabilizing the silo.

[0024] This invention provides a feeding hopper suitable for conveyor belt transport of viscous loess. It has the following beneficial effects:

[0025] By utilizing the good self-lubricating properties of polytetrafluoroethylene (PTFE) sheets, the ability of sticky loess to adhere to the walls is reduced. In addition, by setting up a feeding agitation structure and starting the drive motor, the T-shaped rod is rotated. The rotation of the T-shaped rod causes the stirring rod to agitate the inside of the silo, which helps to prevent sticky loess from accumulating and clogging inside the silo.

[0026] By setting a fixed component and activating the hydraulic rod, its telescopic end drives the extrusion plate to move downward. The downward movement of the extrusion plate compresses the force plate, thereby compressing the vibration spring and achieving the effect of stabilizing the silo. Attached Figure Description

[0038] 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.

[0039] like Figures 1-3 As shown, this embodiment provides a technical solution: a feeding hopper suitable for conveying cohesive loess by belt, comprising a hopper body 1, with a polytetrafluoroethylene (PTFE) plate 9 laid inside the hopper body 1. The PTFE plate 9 is a polymer material product made of PTFE resin through molding, turning and other processes, and has good self-lubricating properties and low wear. A bracket 2 is installed on the hopper body 1, and a vibrating motor 6 is installed on the bracket 2. A feeding agitation structure 7 is provided on the bracket 2. The feeding agitation structure 7 includes a feeding screen cylinder 701, a support block 702 installed on the top of the hopper body 1, and a drive motor 705 installed on the bracket 2. A slip ring 703 is welded to the outside of the feeding screen cylinder 701, and the support block 702 is slidably connected to the slip ring 703. A toothed ring 704 is welded to the outside of the feeding screen cylinder 701. A shaft is installed at the output end of the drive motor 705. A gear 707 is installed at the top of the shaft 706, and the gear 707 meshes with the gear ring 704. A T-shaped rod 709 is installed inside the feed screen cylinder 701, and an agitator 710 is installed on the T-shaped rod 709. The agitator 710 is located inside the silo body 1. According to the above technical solution, specifically, by utilizing the good self-lubricating properties of the polytetrafluoroethylene plate 9, the ability of sticky loess to stick to the wall is reduced. In addition, by starting the drive motor 705, it drives the shaft 706 to rotate. The rotation of the shaft 706 drives the rotation of the gear 707, the rotation of the gear 707 drives the rotation of the gear ring 704, and the rotation of the gear ring 704 drives the rotation of the T-shaped rod 709. The rotation of the T-shaped rod 709 causes the agitator 710 to stir the inside of the silo body 1, which helps to prevent sticky loess from clogging inside the silo body 1.

[0040] Going a step further, such as Figure 2As shown: A screen 708 is installed inside the feed screen cylinder 701. A T-shaped rod 709 is located below the screen 708. By setting the screen 708 and cooperating with the vibration motor 6, the screen 708 vibrates. The cohesive loess falls onto the vibrating screen 708 in advance for vibration treatment. This can pre-disperse the cohesive loess and avoid it from agglomerating into clumps, which helps to reduce the accumulation of cohesive loess in the later stage.

[0041] Going a step further, such as Figure 1 As shown: The feed inlet of the feed screen cylinder 701 is equipped with a feed hopper 711. This design is used to increase the feed inlet and facilitate the loading of materials by the excavator.

[0042] Going a step further, such as Figure 1 As shown: The support 2 includes a force plate 201, a vibration spring 3 is installed at the bottom of the force plate 201, a support leg 4 is installed at the bottom end of the vibration spring 3, and a connecting plate 5 is installed on the support leg 4. The vibration spring 3 helps to improve the vibration capability of the vibration motor 6.

[0043] The above solutions also have the problem that when the entire device is not in use, chamber 1 can still shake significantly, such as... Figure 1 and Figure 3 As shown: In this solution, a fixing component 8 is provided on the connecting plate 5. The fixing component 8 includes a base block 801 installed on the connecting plate 5. A hydraulic rod 802 is installed on the base block 801. A pressing plate 803 is installed on the telescopic end of the hydraulic rod 802. The pressing plate 803 is located above the force plate 201. According to the above technical solution, by activating the hydraulic rod 802, its telescopic end drives the pressing plate 803 to move downward. The downward movement of the pressing plate 803 presses the force plate 201, thereby compressing the vibration spring 3, thus achieving the effect of stabilizing the chamber 1.

[0044] Working principle:

[0045] like Figure 1-3 As shown:

[0046] In use: The good self-lubricating properties of PTFE plate 9 reduce the ability of sticky loess to stick to the wall. In addition, by starting the drive motor 705, it drives the shaft 706 to rotate. The rotation of shaft 706 drives the gear 707 to rotate. The rotation of gear 707 drives the gear ring 704 to rotate. The rotation of gear ring 704 drives the T-shaped rod 709 to rotate. The rotation of T-shaped rod 709 causes the stirring rod 710 to stir the inside of the silo 1, which helps to prevent sticky loess from clogging inside the silo 1.

[0047] By activating the hydraulic rod 802, its telescopic end drives the extrusion plate 803 to move downward. The downward movement of the extrusion plate 803 extrudes the force plate 201, thereby compressing the vibration spring 3, thus achieving the effect of stabilizing the silo body 1.
