Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a port material conveying device with anti-slipping function. Background Technology

[0002] The technical and economic indicators of blast furnace ironmaking are closely related to the stability of raw material composition. Practice shows that a 0.1% reduction in ore grade fluctuations leads to a 0.6%–1.2% decrease in fuel consumption for sintering, a 0.28% increase in sinter production, a 0.3%–0.6% increase in pig iron production, a 0.2%–0.46% decrease in coke ratio, a 0.46% decrease in slag, and a 0.8% decrease in furnace dust. However, currently, steel plants often use diverse and varied ore raw materials, resulting in inconsistent composition, large fluctuations in particle size, and poor overall raw material stability. Improving the stability of raw material composition by blending iron ore received at ports before smelting can effectively improve the technical and economic indicators of blast furnace ironmaking.

[0003] Chinese patent CN118341322A discloses a mobile, high-efficiency mixing and batching vehicle that can move freely and integrates weighing and mixing. Although this batching vehicle can achieve the mixing function of iron ore raw materials in ports, there is still room for improvement. Typically, in the above-mentioned device, because the ore needs to be fed into the mixing equipment through a conveying device, the conveyor belt needs to climb high. Furthermore, due to the limitation of the length of the batching vehicle (the length of the batching vehicle should not be too long, as it is not only inconvenient to move around and has poor flexibility, but also expensive), the existing device has a relatively large conveyor belt angle (approximately 20°). When the material on the belt moves to the head unloading point, because the belt needs to be redirected at the head roller, the material on the head belt is prone to rolling and slipping.

[0004] In summary, there is an urgent need for a port material conveying device with anti-slip function to solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this utility model is to provide a port material conveying device with anti-slip function, aiming to solve the problem that materials are prone to rolling and slipping due to the large inclination angle of the conveyor belt. The specific technical solution is as follows:

[0006] A port material conveying device with anti-slip function includes a feeding assembly, wherein the unloading end of the feeding assembly is higher than its receiving end, and the feeding assembly includes:

[0009] A baffle plate is floatingly disposed in the slot, and the portion of the baffle plate protruding from the back of the conveyor belt is connected to the back of the conveyor belt by an elastic element; when the baffle plate contacts the lifting element, the baffle plate is pushed to protrude from the working surface of the conveyor belt.

[0010] An anti-collision cavity is provided on the roller and is used to accommodate the elastic element and the portion of the baffle plate protruding from the back of the conveyor belt.

[0011] Preferably, the portion of the baffle plate protruding from the back of the conveyor belt includes a connector and a contact member.

[0012] Preferably, a slot is provided on one side of the mounting frame, and the lifting member is inserted between the two rollers through the slot and located below the material conveying section of the conveyor belt.

[0013] Preferably, the surface in contact between the lifting member and the contacting member is an inclined surface, or a combination of a plane and an inclined surface;

[0014] The lifting component is used to lift up a portion of the baffle plate near the unloading end, or to lift up all the baffle plates in the entire material conveying section.

[0015] Preferably, a first belt assembly is provided between the two rollers, and one of the rollers is connected to the drive unit.

[0016] Preferably, it also includes a mixing component, which includes a mixing frame and a mixing wheel rotatably disposed in the mixing frame, wherein the inlet of the mixing frame is disposed at the discharge end of the feeding component.

[0019] Preferably, the first support member is hinged to the mounting frame and the base plate, and the first support member can extend and retract along its own length; the second support member is hinged to the mounting frame.

[0020] Preferably, a guide plate is provided between the inlet of the mixing frame and the unloading end of the feeding component, and the guide plate is connected to the mixing frame.

[0021] The application of the technical solution of this utility model has the following beneficial effects:

[0022] The feeding assembly of this invention, with its lifting component, contact component, elastic component, and baffle plate working together, enables the baffle plate to be lifted to block the material and solve the problem of material slippage.

[0031] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] Example:

[0034] See Figures 1-4 This embodiment provides a port material conveying device with anti-slip function, including a feeding assembly with the unloading end of the feeding assembly higher than its receiving end. The feeding assembly includes:

[0035] The mounting frame 2 has rollers 3 rotatably mounted at both the unloading end and the receiving end. The two rollers 3 are equipped with conveyor belts 5, and the conveyor belts 5 are provided with multiple slots 6 spaced apart along their circumference.

[0036] The lifting component 12 is located between the two rollers 3 and below the material conveying section of the conveyor belt 5;

[0037] The baffle plate 7 is floating (i.e. sliding) in the slot 6, and the portion of the baffle plate protruding from the back of the conveyor belt 5 is connected to the back of the conveyor belt 5 by an elastic member 9; when the baffle plate 7 contacts the lifting member 12, the baffle plate 7 is pushed to protrude from the working surface of the conveyor belt 5.

[0038] Anti-collision cavity 4 is provided on the roller 3 and is used to accommodate the elastic element 9 and the portion of the baffle plate 7 protruding from the back of the conveyor belt 5.

[0039] Preferably, the anti-collision recess 4 is positioned corresponding to the portions of the elastic element 9 and the baffle plate 7 that protrude from the back of the conveyor belt 5, that is, during the movement, the portions of the elastic element 9 and the baffle plate 7 that protrude from the back of the conveyor belt 5 can just pass through the anti-collision recess 4, thereby preventing interference between the roller 3 and the portions of the elastic element 9 and the baffle plate 7 that protrude from the back of the conveyor belt 5; furthermore, the anti-collision recess 4 is a concave notch arranged circumferentially along the roller.

[0040] Specifically, the material conveying section refers to the section on the conveyor belt 5 that carries and transports the material. The working surface of the conveyor belt 5 refers to the side that carries the material, and the back surface of the conveyor belt 5 refers to the side that contacts the roller 3. In this embodiment, by pushing the baffle 7 to protrude from the working surface of the conveyor belt 5, the material is blocked, thereby preventing material from slipping on the inclined conveyor belt.

[0041] See Figure 1 and Figure 2 The portion of the baffle plate 7 protruding from the back of the conveyor belt 5 includes a connector 8 and a contact member 10. One end of the contact member 10 is connected to the baffle plate 7, and the other end is used to contact the lifting member 12. Connectors 8 are evenly distributed around the contact member 10. The connectors 8 are connected to the back of the conveyor belt 5 through elastic members 9.

[0042] Furthermore, the thickness of the baffle plate is the same as the thickness of the conveyor belt. In its natural state, the upper surface of the baffle plate 7 is flush with the working surface of the conveyor belt, and its lower surface is flush with the back surface of the conveyor belt, thereby ensuring the flatness of the working surface of the conveyor belt. In this embodiment, the portion of the baffle plate 7 that protrudes from the back surface of the conveyor belt 5 refers to the portion of the elastic element that protrudes from the back surface of the conveyor belt in its natural state.

[0043] Furthermore, in this embodiment, the two sides of the contact member 10 are symmetrically provided with connecting members 8, and the straight line formed by the two connecting members is parallel to the direction of movement of the conveyor belt. This arrangement can reduce the size of the anti-collision cavity and minimize the impact of the reduced contact area between the roller and the conveyor belt and the decrease in the structural strength of the roller caused by the anti-collision cavity.

[0044] Preferably, in some embodiments, the elastic element may be arranged in other structural forms. For example, the elastic element is sleeved on the contact element 10, the contact element has a shoulder at its lower end, one end of the elastic element is connected to the back of the conveyor belt, and the other end is connected to the shoulder. This arrangement can also meet the requirement of floating baffle 7.

[0045] Preferably, the elastic element is a spring, and the contact element 10 and the lifting element 12 are in sliding contact. The contact element 10 is spherical to reduce the contact area between the contact element and the lifting element and reduce the movement resistance. Of course, in some embodiments, the contact element 10 and the lifting element 12 may be in rolling contact, such as the end of the contact element 10 being a roller, which can also achieve the effect of reducing the movement resistance between the contact element and the lifting element.

[0046] Preferably, the groove 6 can be in the shape of a straight line or a V-shape, and the shape of the baffle plate is consistent with the shape of the groove; the length direction of the baffle plate 7 is parallel to the width direction of the conveyor belt, thereby achieving the effect of blocking the material on the conveyor belt.

[0047] See Figure 3 The mounting frame 2 has a slot 11 on one side, through which the lifting member 12 is inserted between the two rollers 3 and located below the material conveying section of the conveyor belt 5. Furthermore, the surface of the lifting member 12 that contacts the contact member 10 is an inclined surface; in this embodiment, the lifting member 12 is positioned near the unloading end. Because the surface of the lifting member 12 that contacts the contact member 10 is an inclined surface, the distance between the inclined surface and the back of the conveyor belt decreases along the direction of conveyor belt movement. Therefore, the baffle plate can be gradually lifted as the conveyor belt moves, ensuring the smoothness of the baffle plate lifting process.

[0048] Preferably, in some embodiments, the lifting member 12 may be configured to lift all the baffles of the entire material conveying section, that is, the working surface of the entire material conveying section is divided into multiple sections by multiple baffles. In this structural form, the material conveying section is divided into several sections, and each section has a baffle to block the material to prevent material from slipping (i.e., to prevent the material from slipping into other sections). In this arrangement, the surface in contact with the lifting member and the contact member can be composed of an inclined surface and a plane. The inclined surface is used to gradually lift the baffle, and the plane is used to keep the baffle in the lifted state.

[0049] Preferably, in some embodiments, an inclined surface may also be provided at the end of the lifting member (the end position where the contact member is about to leave the lifting member) so that the baffle plate can be gradually reset.

[0050] Preferably, in some embodiments, the lifting member may be directly fixedly connected to the mounting frame 2.

[0051] See Figure 3A first belt assembly 14 is provided between the two rollers 3, and one of the rollers 3 is connected to the drive component. The first belt assembly 14 enables the two rollers 3 to move synchronously, minimizing slippage between the conveyor belt and the rollers. The drive component refers to an external drive component used to drive the rollers to rotate. The drive component is preferably a combination of a motor and a reducer.

[0052] See Figure 1 , Figure 3 and Figure 4 The material conveying device further includes a mixing component, which includes a mixing frame 15 and a mixing wheel 16 rotatably disposed in the mixing frame 15. The inlet of the mixing frame 15 is located at the discharge end of the feeding component. After the material conveyed by the feeding component enters the mixing frame 15, it is uniformly mixed by the mixing wheel 16.

[0053] See Figure 1 The mixing wheel 16 includes a rotating shaft 16.2 and a plurality of mixing blades 16.1 arranged circumferentially along the rotating shaft 16.2. The rotating shaft 16.2 is rotatably mounted on the mixing frame 15, and the rotating shaft 16.2 is connected to one of the rollers 3 via a second belt assembly 18. The second belt assembly 18 enables the mixing wheel 16 and the rollers 3 to rotate synchronously, eliminating the need for a separate drive device for the mixing wheel 16. Preferably, the mixing blades 16.1 are made of elastic material to prevent damage to the mixing blades due to collisions when in contact with the material, and also to prevent the material from splashing out during mixing.

[0054] Furthermore, the material conveying device also includes a base plate 1. The mixing component is disposed on the base plate 1, and the base plate 1 has a receiving port 21 below the discharge port of the mixing frame 15. The receiving port 21 is for the convenience of receiving equipment to take away the material from under the mixing frame. In production, the commonly used receiving equipment is a stacker. The tail of the stacker can extend into the receiving port 21 to take away the mixed material and pile it up. The unloading end of the mounting frame 2 is disposed on the base plate 1 through the first support member 13, and its receiving end is disposed on the base plate 1 through the second support member 20. The first support member 13 and the second support member 20 support the feeding component, so that the unloading end of the feeding component is higher than its receiving end. In this embodiment, the lengths of the first support member and the second support member are both fixed values.

[0055] Preferably, in some embodiments, the first support member 13 may be able to extend and retract along its own length. The first support member 13 is hinged to the mounting frame 2 and the base plate 1, and the second support member 20 is hinged to the mounting frame 2, thereby achieving the purpose of adjusting the tilt angle of the feeding assembly. Since the static angle of repose varies among different batches and types of materials, the movement of the first support member 13 can adjust the tilt angle of the feeding assembly according to different batches and types of materials, further preventing materials from rolling on the conveyor belt. Preferably, the first support member 13 is one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0056] See Figure 1 , Figure 3 and Figure 4 A guide plate 17 is provided between the inlet of the mixing frame 15 and the unloading end of the feeding assembly. The guide plate 17 is connected to the mixing frame 15. Furthermore, the guide plate 17 overlaps the conveyor belt. The guide plate is preferably made of elastic material. The guide plate allows the material on the conveyor belt to enter the mixing frame 15 stably, which serves to receive the material and effectively prevent spillage.

[0057] Preferably, when the first support member 13 can extend and retract along its own length, the guide plate and the mixing frame 15 are hinged together, so that the guide plate can be adjusted according to the tilt angle of the feeding assembly; when the first support member 13 cannot extend and retract along its own length, the guide plate and the mixing frame 15 can be hinged or fixed together.

[0058] Preferably, in some embodiments, the guide plate 17 may not be provided. When the guide plate 17 is not provided, the material on the conveyor belt falls directly into the mixing frame 15 by inertia.

[0059] Preferably, the lower part of the base plate 1 is provided with a walking mechanism 19, so that the material conveying device in this embodiment can be flexibly adjusted in position; the walking mechanism 19 can be a walking wheel or a universal wheel, etc. Please refer to the prior art for details, which will not be described in detail in this embodiment.

[0060] In use, the lifting member 12 is inserted into the slot 11, and the driving member drives the roller 3 to rotate, transporting materials via the conveyor belt. During transportation, when the contact member 10 contacts the lifting member 12, the baffle plate 7 is slowly lifted, blocking the material and preventing it from rolling on the conveyor belt 5 and causing slippage. This ensures that the material on the conveyor belt 5 can be stably transported to the mixing frame 15, improving the stability of material transportation. The material entering the mixing frame 15 is mixed evenly due to the rotation of the mixing wheel 16. The mixing blades 16.1 are made of elastic material to prevent them from colliding with the material and causing damage, while also preventing the material from splashing out during mixing. The walking mechanism 19 facilitates the movement of the base plate 1 and supports the entire material conveying device.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
