Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, specifically to an energy-saving scraper conveyor. Background Technology

[0002] Scraper conveyors, as important continuous conveying equipment for bulk materials, are widely used in industries such as mining, metallurgy, chemical industry, and food processing due to their advantages such as simple structure, reliable operation, and ability to convey horizontally or at small angles. Their basic working principle involves a motor driving a chain, which in turn drives scrapers fixed to the chain to push materials forward within a closed trough. In traditional scraper conveyors, the scrapers typically slide directly against the bottom plate of the trough while pushing materials. This continuous sliding friction is one of the main sources of energy loss and leads to rapid wear on both the scrapers and the bottom plate, especially when conveying materials with high hardness and large size. Existing designs often have a fixed distance between the scrapers and the bottom plate. This fixed structure has poor adaptability to different working conditions. For example, when conveying large pieces of material, the material itself can form an effective conveying layer, and the scrapers do not need to contact the bottom plate; the fixed contact causes unnecessary energy waste and wear. Conversely, when conveying fine powder materials, if a large gap is reserved to reduce wear, it will cause serious material leakage and reduce conveying efficiency.

[0003] Furthermore, in the initial stage when materials enter the hopper from the feed inlet, some materials with poor flowability or high moisture content, such as wet coal, fly ash, or clay, may arch or bridge within the hopper, leading to poor material discharge or even complete blockage. This seriously affects the continuous and stable operation and overall working efficiency of the scraper conveyor. Most existing scraper conveyors lack an effective device for actively breaking arches and agitating and dispersing materials at the feed inlet. Therefore, how to design a scraper conveyor that can intelligently adjust its operating status according to the characteristics of the material to reduce energy consumption, reduce wear, and simultaneously solve the problem of feed blockage has become a technical challenge that urgently needs to be solved in this field.

[0004] Therefore, this utility model proposes an energy-saving scraper machine to overcome the shortcomings of the prior art. Summary of the Invention

[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide an energy-saving scraper conveyor, which solves the technical problems of high energy consumption, severe wear or material leakage when conveying different materials due to the fixed gap of the bottom plate in related technologies / existing technologies, as well as easy blockage of the feed inlet and single function.

[0006] This utility model provides an energy-saving scraper conveyor, comprising: a housing, a rotating shaft, a sprocket, a chain, a scraper, and a motor; as well as an anti-friction mechanism.

[0007] The anti-friction mechanism has an adjustable structure, including a liftable base plate, a base for supporting the base plate, a sliding plate that can slide within the base, and wedges one and two respectively disposed on the sliding plate and the base plate.

[0008] Furthermore, the anti-friction mechanism also includes a threaded rod rotatably located at the bottom left side of the housing, a threaded sleeve fixedly connected to the front side of the slide plate, and a throttle connected to the threaded rod. The threaded rod and the threaded sleeve are combined by a threaded connection so that the slide plate can be driven to slide horizontally by rotating the throttle, and the horizontal movement is converted into the vertical lifting and lowering movement of the base plate by the inclined surface cooperation of wedge one and wedge two.

[0009] For example, at least one embodiment of this disclosure provides an energy-saving scraper conveyor, which further includes an anti-blocking mechanism disposed in a chute communicating with the top of the housing, and includes a rotating rod and a lever for agitating the material. For example, at least one embodiment of this disclosure provides an energy-saving scraper conveyor in which the rotating rod is connected to the rotating shaft via a first transmission wheel, a second transmission wheel, and a first transmission belt, thereby achieving synchronous anti-blocking with the main conveying system.

[0010] For example, at least one embodiment of this disclosure provides an energy-saving scraper conveyor in which two rotating rods are provided in the chute. The two rotating rods are connected by a transmission wheel three and a transmission belt two at their respective front ends to achieve synchronous rotation and enhance the stirring effect.

[0011] For example, in at least one embodiment of this disclosure, an energy-saving scraper machine is provided, wherein wedges are fixed on the top left and right sides of the slide plate and wedges are fixed on the bottom left and right sides of the base plate to ensure the smoothness of the lifting process.

[0012] For example, at least one embodiment of this disclosure provides an energy-saving scraper machine in which a plurality of bases are fixedly connected to the bottom of the housing, and the same sliding plate is slidably connected to the top of the plurality of bases to enhance support stability.

[0013] For example, in at least one embodiment of this disclosure, an energy-saving scraper machine is provided, wherein the first wedge and the second wedge further include a plane that can contact each other. When the slide plate slides to a preset position, the planes contact each other, providing a stable highest position support for the base plate.

[0014] For example, at least one embodiment of this disclosure provides an energy-saving scraper conveyor in which the chute is disposed on the left side of the top of the housing to make the transmission structure more compact.

[0015] For example, at least one embodiment of this disclosure provides an energy-saving scraper conveyor in which the rotating shaft on the right side is connected to the output end of the motor, and the rotating shaft on the left side is fixedly connected to the transmission wheel to achieve clear power distribution.

[0016] For example, at least one embodiment of this disclosure provides an energy-saving scraper conveyor in which the length of the base plate is shorter than the length of the shell, the left end of the base plate is attached to the inner left end of the shell, and the gap between the left side of the base plate and the inner right end of the shell is used for discharging materials.

[0017] The beneficial effects of this utility model are as follows: 1. This utility model, by setting an anti-friction mechanism composed of a threaded rod, a sliding plate, and a wedge block assembly, realizes dynamic adjustment of the bottom plate height, which solves the problems of fixed bottom plate gap in the prior art of scraper conveyors, which leads to high frictional energy consumption and severe wear when conveying large materials, and easy leakage when conveying small materials. It achieves the technical effect of flexibly adjusting the operating gap according to the material characteristics, significantly reducing ineffective energy consumption, extending the service life of the equipment, and improving the adaptability of conveying.

[0018] 2. This utility model solves the problem of material accumulation and blockage at the feed inlet due to poor flowability or easy agglomeration when entering the scraper conveyor by setting an agitator rod in the feed chute that is synchronously linked with the main drive system. It achieves the technical effect of actively breaking up material bridging, ensuring continuous and smooth feeding, and thus improving the working efficiency and stability of the whole machine.

[0028] Please refer to Figures 1 to 4 As shown, an energy-saving scraper conveyor includes a housing 1 as the main frame and a motor 201 mounted on the housing 1, an anti-blocking mechanism 2, and an anti-friction mechanism 3. Two rotating shafts 202 are rotatably connected inside the housing 1. Sprockets 4 are fixedly connected to the front and rear sides of the outer walls of the two rotating shafts 202. The sprockets 4 on the same side are connected by a chain 5. Multiple scrapers 6 are fixedly connected between the chains 5 on both sides, forming a conveying system for transporting materials. The front end of the rotating shaft 202 on the right side passes through the housing 1 and is connected to the output end of the motor 201. The motor 201 provides power to the conveying system. The anti-blocking mechanism 2 is located at the feed end at the top of the housing 1 and is used to agitate the material. The anti-blocking mechanism 2 includes a chute 204 communicating with the top of the housing 1, a rotating rod 205 rotatably disposed within the chute 204, and a lever 210 fixed to the rotating rod 205. The anti-friction mechanism 3 is located within the housing. At the bottom of 1, the running gap between the scraper 6 and the bottom plate of the housing 1 is adjusted. The anti-friction mechanism 3 includes a base 301 fixedly connected to the bottom of the housing 1, a slide plate 302 slidably connected to the base 301, a wedge 303 fixed to the top of the slide plate 302, a bottom plate 304 slidably connected to the bottom of the inner side of the housing 1, a wedge 305 fixed to the bottom of the bottom plate 304, a threaded sleeve 306 fixedly connected to the front side of the slide plate 302, a threaded rod 307 rotatably connected to the side wall of the housing 1, and a handle 308 connected to the outer end of the threaded rod 307. The front end of the rotating shaft 202 on the left side passes through the housing 1 and is fixedly connected to the transmission wheel 203, which is used to provide power to the anti-blocking mechanism 2. The transmission wheel 203, the transmission wheel 206, the transmission belt 207, the transmission wheel 208, and the transmission belt 209 together constitute the transmission component of the anti-blocking mechanism 2.

[0029] Please refer to Figure 2 and Figure 3The anti-friction mechanism 3 includes multiple bases 301 fixedly connected to the bottom of the housing 1. A sliding plate 302 is slidably connected to the inner top of each base 301. Wedge blocks 303 are fixedly connected to the left and right sides of the top of the sliding plate 302. A base plate 304 is slidably connected to the bottom inner side of the housing 1. Wedge blocks 305 are fixedly connected to the left and right sides of the bottom of the base plate 304. The inclined surfaces of wedge blocks 303 and 305 slide in contact with each other. A threaded sleeve 306 is fixedly connected to the front of the sliding plate 302. A threaded rod 307 is rotatably connected to the bottom left side of the housing 1. The outer wall of the threaded rod 307 and the inner wall of the threaded sleeve 306 form a threaded connection. A handle 308 is connected to the threaded rod 307. Rotating the handle 308 drives the threaded rod 307 to rotate. Since the threaded sleeve 306 moves with the sliding plate... 302 can only move in a straight line and cannot rotate. The rotation of the threaded rod 307 drives the threaded sleeve 306 through the threaded engagement, and causes the slide plate 302 to slide back and forth horizontally inside the base 301. The horizontal sliding of the slide plate 302 causes the inclined surfaces of wedge 1 303 and wedge 2 305 to be relatively displaced. By utilizing the force-saving principle of the wedge structure, the horizontal movement is converted into vertical movement, thereby lifting or lowering the base plate 304. This linkage structure of the screw and the double wedge block group ensures the stability and accuracy of the lifting and lowering adjustment of the base plate 304. Wedge 1 303 and wedge 2 305 also include planes that can contact each other. When the slide plate 302 moves to the preset limit position, the plane of wedge 1 303 contacts the plane of wedge 2 305, which can provide a stable highest position support for the base plate 304.

[0030] As a preferred embodiment, to achieve active anti-blocking during material entry, an energy-saving scraper conveyor also includes an anti-blocking mechanism 2, please refer to... Figure 1 and Figure 4 The anti-blocking mechanism 2 includes a chute 204 fixedly connected to the top of the housing 1. A rotating rod 205 is rotatably connected inside the chute 204. Multiple levers 210 for stirring the material are fixedly connected to the outer wall of the rotating rod 205. To achieve linkage, the front end of the rotating shaft 202 on the left is fixedly connected to the first transmission wheel 203, and the front end of the rotating rod 205 is fixedly connected to the second transmission wheel 206. The first transmission wheel 203 and the second transmission wheel 206 are connected by a transmission belt 207, so that the anti-blocking mechanism 2 works synchronously with the main conveying system.

[0031] As a further optimization of the anti-blocking mechanism 2, in order to enhance the agitation effect on the materials, please refer to... Figure 4 The chute 204 has two rotating rods 205 that can be rotatably connected inside. The front ends of the two rotating rods 205 are fixedly connected to the transmission wheel 208. The two transmission wheels 208 are connected by the transmission belt 209, which ensures that the two rotating rods 205 can rotate synchronously and disperse the incoming material more evenly and fully.

[0032] As a preferred arrangement of the power transmission path, the front end of the right-side rotating shaft 202 passes through the housing 1 and is connected to the output end of the motor 201 to drive the operation of the entire conveying system. The front end of the left-side rotating shaft 202 passes through the housing 1 and is fixedly connected to the transmission wheel 203, which is specifically responsible for transmitting power from the main conveying system to the anti-blocking mechanism 2, making the overall structural layout clear and reasonable.

[0033] As an optimization of the stability of the anti-friction mechanism 3, wedges 303 are fixed on the top left and right sides of the slide plate 302, and wedges 305 are fixed on the bottom left and right sides of the base plate 304. In addition, multiple bases 301 are fixedly connected to the bottom of the housing 1. The same slide plate 302 is slidably installed on the top of all the bases 301. Through the structure of multi-point support and double wedge block group, the base plate 304 is more stable during the lifting process and when bearing heavy material pressure, and is less prone to tilting.

[0034] As a preferred design for the feeding position, the chute 204 is located on the top left side of the housing 1. This position is close to the transmission wheel 203 that provides power to the anti-blocking mechanism 2, which can shorten the length of the transmission belt 207, making the transmission structure more compact and reducing space occupation.

[0035] Working principle: When motor 201 starts, it drives the right-side rotating shaft 202 to rotate, which in turn drives multiple scrapers 6 connected between the chains 5 on both sides to circulate along the inner wall of the housing 1 through the transmission of sprocket 4 and chain 5, thus realizing the basic conveying function of materials. At the same time, the left-side rotating shaft 202 rotates synchronously, and through the transmission wheel 203 fixedly connected to its front end, drives the transmission wheel 206 on the rotating rod 205 set in the chute 204 to rotate via the transmission belt 207. If there are two The rotating rod 205 is connected to the transmission belt 209 via the transmission wheel 3 208 at its front end, so as to achieve synchronous or same-direction rotation. The rotation of the rotating rod 205 drives multiple levers 210 on the outer wall to continuously agitate and disperse the material entering the shell 1 from the chute 204. This anti-blocking mechanism 2, which is linked with the main transmission system, can effectively prevent the accumulation, bridging or blockage of powdery, lumpy or sticky materials at the feed inlet, and ensure that the material can enter the main conveying area smoothly and evenly. The anti-friction mechanism 3 is designed to precisely adjust the height of the base plate 304 according to the volume of the transported material. The adjustment process involves two working conditions. When transporting fine powder or granular materials, the operator rotates the handle 308 clockwise or counterclockwise. The handle 308 drives the threaded rod 307 to rotate. Because the threaded sleeve 306, which is fixedly connected to the front end of the sliding plate 302, cannot rotate due to the limitation imposed by the base 301, the threaded sleeve 306, under the action of the threaded engagement, pushes the sliding plate 302 to the right along the axis of the threaded rod 307. During the sliding process of the sliding plate 302, its… The inclined surfaces of the first wedge 303 on the top left and right sides slide along the inclined surfaces of the second wedge 305 on the bottom left and right sides of the base plate 304. Utilizing the force amplification and conversion principle of the wedge structure, the horizontal movement of the slide plate 302 is converted into the vertical upward movement of the base plate 304, thereby smoothly lifting the base plate 304 until the top of the base plate 304 is in complete contact with the bottom of the scraper 6 or maintains a very small gap. At this point, the planes that may be provided on the first wedge 303 and the second wedge 305 can also contact each other to provide stable end support. In this state, small materials can be prevented from leaking under the scraper 6 to the greatest extent possible. This significantly improves conveying efficiency and material cleaning rate. When transporting large block materials, the operator reverses the rotation of the handle 308, causing the threaded rod 307 to rotate in the opposite direction, which in turn drives the threaded sleeve 306 and the sliding plate 302 to retract to the left. As the inclined support surfaces of wedge 1 303 and wedge 2 305 gradually shift apart, the bottom plate 304 descends smoothly under its own weight, thus forming a pre-set, large operating gap between the bottom of the scraper 6 and the top of the bottom plate 304. In this state, the scraper 6 no longer rubs against the bottom plate 304 during its cyclical movement, but merely pushes the material accumulated on the bottom plate 304. The material layer above 04 advances, which greatly reduces the sliding friction resistance between the two large-area components, scraper 6 and base plate 304, directly reducing the operating load of motor 201 and ineffective energy consumption, resulting in significant energy saving. At the same time, by avoiding direct hard scraping between scraper 6 and base plate 304, the wear of the two key components is also greatly reduced, effectively extending the service life of the equipment and reducing operating and maintenance costs. Through the ingenious adjustment function of anti-friction mechanism 3, this utility model solves the problem of energy waste and component wear caused by the inability to take into account different working conditions due to the fixed structure in the prior art.
