Description

Technical Field

[0001] This utility model relates to the field of anti-clogging technology for receiving hoppers, and in particular to an anti-clogging receiving hopper. Background Technology

[0002] With industrial development, the demand for transporting bulk materials such as coal and ore has increased significantly, leading to increasingly prominent material blockage problems in receiving hoppers during frequent unloading. Bulk materials from different sources and for different purposes exhibit vastly different characteristics. In modern industry, the moisture content, viscosity, and particle size distribution of bulk materials have become more complex. Some ores acquire large amounts of moisture and sticky substances during mining, and coal may become damp and deteriorate during storage and transportation. These complex material characteristics increase the difficulty of unloading from receiving hoppers, making material blockage problems more common.

[0003] When handling high-humidity, high-viscosity materials, the material easily adheres to the inner wall of the receiving hopper, forming accumulations. During the unloading process, the receiving hopper is frequently subjected to the impact of large amounts of material, increasing the risk of blockage. Frequent blockages not only lead to material leakage and environmental pollution but may also cause safety accidents during cleanup. To meet environmental and safety standards, companies need to address the problem of receiving hopper blockages to reduce material leakage and safety hazards.

[0004] Conventional measures to prevent material blockage in receiving hoppers involve installing air cannons or electric vibration devices, or both, at appropriate locations on the hopper body, along with manual hammering. This method is labor-intensive and ineffective at clearing blockages. Furthermore, it is susceptible to seasonality and material moisture content, making conventional methods inconvenient for cleaning and preventing hopper blockages, leading to uneven material discharge, impeded material transport, and frequent equipment downtime, thus impacting work efficiency. Additionally, the high impact of air cannons and electric vibration devices on the receiving hopper causes material vibration and friction, shortening the lifespan of the hopper and related equipment, increasing maintenance and replacement costs, and extending downtime. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides an anti-clogging receiving hopper. A cutting disc and a cutting shaft are set at the bottom of the receiving hopper. The cutting disc and the cutting shaft cut and rotate to disperse the material at the bottom of the receiving hopper, preventing the material from clogging at the bottom of the receiving hopper, extending the service life of the receiving hopper and related equipment, reducing equipment maintenance and replacement costs, reducing production downtime caused by equipment failure, and improving the reliability and stability of equipment operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clog-resistant receiving hopper includes a receiving hopper, a discharging hopper, and a transmission cutting mechanism. The receiving hopper has a discharging hopper at its bottom, and the discharging hopper has a transmission cutting mechanism inside. The transmission cutting mechanism includes cutting discs and cutting shafts. The cutting shafts pass through the discharging hopper, and at least two cutting shafts are provided. Several cutting discs are obliquely arranged on the cutting shafts inside the discharging hopper. The cutting discs and the cutting shafts form a cutting angle. The cutting discs are evenly distributed at equal intervals on the cutting shafts inside the discharging hopper, and the cutting discs between two adjacent cutting shafts are arranged in a cross-interval manner.

[0008] Furthermore, the transmission cutting mechanism also includes a coupling, a short shaft, a bearing housing, and a motor reducer. Each cutting shaft is equipped with a coupling at both ends, with one end coupling connected to the output shaft of the motor reducer and the other end coupling connected to the bearing housing via the short shaft.

[0009] Furthermore, the bearing housing and the motor reducer are based on the base of the conveyor belt roller assembly located at the bottom of the hopper.

[0010] Furthermore, the motor reducers on each cutting shaft rotate synchronously.

[0011] Furthermore, the feeding hopper is a cylindrical hopper with vertical walls.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) Improve production efficiency: The bottom of the receiving hopper is equipped with a transmission cutting mechanism to break up the material at the bottom of the receiving hopper, prevent the material from blocking the receiving hopper, improve unloading efficiency, reduce unloading time, reduce the interruption of the tipper's work, improve the working efficiency of the tipper, reduce the number of production interruptions, increase the amount of material processed per unit time, and ensure the smooth progress of the enterprise's production plan.

[0014] 2) Reduce equipment wear: Use a bottom-drive cutting mechanism to prevent blockage, avoid using air cannons and electric shock hoppers to reduce impact and friction on the equipment, extend the service life of the receiving hopper and related equipment, reduce equipment maintenance and replacement costs, reduce production downtime caused by equipment failure, and improve the reliability and stability of the equipment.

[0015] 3) Ensure personnel safety: Reducing the occurrence of material blockage can decrease the frequency of dangerous cleaning operations by operators and improve their safety. Attached Figure Description

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0025] In the description of this patent, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0026] For ease of description, spatial relative terms such as "above," "over," "on the upper surface," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly. Unless otherwise stated, the above terms have no special meaning and should not be construed as limiting the scope of protection of this utility model.

[0027] like Figure 1-7 As shown, the working principle of an anti-clogging receiving hopper is as follows: A columnar discharge hopper 2 is set at the bottom of the receiving hopper 1. The discharge hopper 2 is equipped with a transmission cutting mechanism 3. The cutting shaft 302 of the transmission cutting mechanism 3 passes through the discharge hopper 2. A chip disc 301 is set inside the discharge hopper 2. The rotation of the cutting shaft 302 and the cutting disc 301 agitates and cuts the material in the discharge hopper 2 into small pieces, preventing the material from clogging at the bottom of the receiving hopper 1. The cutting disc 301 and the cutting shaft 302 are at a certain angle. During the rotation of the cutting shaft 302, the material is compressed and discharged from the discharge port, avoiding the accumulation of material and blockage. At the same time, the angled cutting disc 301 can also scrape the material off and send it out of the discharge port, further preventing clogging.

[0028] like Figure 1-7As shown, an anti-clogging receiving hopper includes a receiving hopper 1, a discharging hopper 2, and a transmission cutting mechanism 3. The top of the receiving hopper 1 is located under a concrete frame 8, which is constructed simultaneously with the factory foundation. A pre-embedded steel plate 7 is embedded in the concrete frame 8 so that it can be used to weld the receiving hopper 1 after the concrete has cured and formed. The bottom of the receiving hopper 1 is provided with the discharging hopper 2, and the transmission cutting mechanism 3 is installed inside the discharging hopper 2. The transmission cutting mechanism 3 is the main structure. When the receiving hopper 1 is blocked, the discharging hopper 2 cannot discharge material. By activating the transmission cutting mechanism 3, the blockage can be effectively eliminated. The transmission cutting mechanism 3 includes a cutting disc 301 and a cutting shaft 302. The cutting shaft 302 passes through the feeding hopper 2. Two cutting shafts 302 are provided, and the number of cutting shafts 302 is determined according to the volume of the receiving hopper 1 and the cross-sectional dimensions of the feeding hopper 2, ensuring that the entire bottom of the receiving hopper 1 can be cut and agitated to prevent blockage. Four cutting discs 301 are obliquely arranged on the cutting shafts 302 inside the feeding hopper 2. The number of cutting discs 301 is determined according to the size of the feeding port 2, satisfying the requirement of agitation during feeding when the feeding hopper 2 is blocked. The cutting discs 301 and the cutting... The cutting shafts 302 form a chip angle θ, which allows the cutting shafts 302 to not only cut the accumulated and stuck materials during rotation, but also scrape the accumulated materials off and send them to the lower conveyor belt 4. The several cutting discs 301 are evenly distributed at intervals on the cutting shafts 302 in the hopper 2. The cutting discs 301 between two adjacent cutting shafts 302 are arranged in a cross-interval Δ. The cross-interval Δ between two adjacent cutting discs 301 between two cutting shafts 302 can ensure that large pieces of material accumulated in the material enter the cross-interval Δ area and are cut into smaller pieces.

[0029] Furthermore, the transmission cutting mechanism also includes a coupling 303, a short shaft 304, a bearing housing 305, and a motor reducer 306. Each cutting shaft 302 is provided with a coupling 303 at both ends, with one end of the coupling 303 connected to the output shaft of the motor reducer 306, and the other end of the coupling 303 connected to the bearing housing 305 via the short shaft 304. In order to avoid the cutting shaft 302 in the transmission cutting mechanism 3 from being designed too long, which would reduce the strength and rigidity of the cutting shaft 302 and cause frequent damage to the cutting shaft 302, a short shaft 304 is added to the cutting shaft 302 via the coupling 303.

[0030] Furthermore, the bearing housing 305 and the motor reducer 306 are based on the base 6 of the conveyor belt 4 and the idler roller group 5 at the bottom of the hopper 2. The conveyor belt 4 is the main component that transports the material from the outlet to the next process. The main function of the idler roller group 5 and the base 6 is to support the conveyor belt. The bearing housing 305 and the motor reducer 306 in the transmission cutting mechanism 3 are based on the base 6, which transmits the load and vibration to the foundation through the base 6, preventing the transmission cutting mechanism 3 from deforming.

[0031] Furthermore, the motor reducer 306 on each cutting shaft 302 rotates synchronously.

[0032] Furthermore, the feeding hopper 2 is a cylindrical hopper with vertical walls, and the four sides of the feeding hopper 2 are perpendicular to the bottom conveyor belt 4, which improves the smoothness of material feeding.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
