Description

Technical Field

[0001] This utility model relates to the field of ore screening equipment, specifically to an inclined vibrating screen. Background Technology

[0002] The process of separating loose materials into different particle sizes through a sieve is called ore screening. In mineral processing plants, screening is often combined with crushing operations. Before the ore enters a certain crusher, a screening machine is needed to pre-separate the ore into those that already meet the particle size requirements and those that still need to be crushed. This can prevent the ore from being over-crushed and improve the production efficiency of the crusher.

[0003] In the existing technology, there are many types of screening machinery used in mineral processing plants, and vibrating screens are among the more commonly used equipment, such as eccentric vibrating screens. Specifically, in the design of eccentric vibrating screens, the screen surface is usually inclined so that the ore can move along the screen surface and be output outward. However, in actual use, the ore discharged from the screen surface of existing eccentric vibrating screens is usually directly discharged to the ground and then collected manually. This method of ore discharge is not only inconvenient to collect and difficult to continuously screen the ore, but also the discharged ore is easy to mix together again. Utility Model Content

[0004] The purpose of this utility model is to provide an inclined vibrating screen to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides an inclined vibrating screen, including a vibrating screen body. The screening and sliding direction of the vibrating screen body is inclined downward from back to front along the longitudinal direction. A single layer of screen is provided on the vibrating screen body along its own screening and sliding direction. The screen is unfolded and arranged in the inner middle of the vibrating screen body to divide the interior of the vibrating screen body into two screening spaces through the screen.

[0007] The front part of the vibrating screen body is provided with two layers of material guiding and conveying components, and the two layers of material guiding and conveying components are respectively flush with the front end of the screen and the front end of the bottom of the vibrating screen body, so as to gather and collect the mineral material and convey it outward with the help of the two layers of material guiding and conveying components and avoid discharge congestion.

[0008] On both sides of the front part of the vibrating screen body, a disassembly assembly is provided at the position corresponding to the material conveying component. The disassembly assembly is partially fixed to the side of the material conveying component, and the material conveying component is detachably fixed to the front part of the vibrating screen body through the disassembly assembly.

[0009] Preferably, the vibrating screen body is an eccentric vibrating screener.

[0010] Preferably, each of the material conveying components includes a guide plate and a material gathering plate. The guide plates are respectively located at the front end of the screen and the bottom end of the vibrating screen body. The guide plates extend outward at an angle along the screening and sliding direction of the vibrating screen body. Material gathering plates are vertically extended and fixed on the top of both sides of the guide plates. The material gathering plates on both sides of the same layer are distributed in a figure-eight shape with the small opening at the front. At the same time, the disassembly and assembly components are respectively fixed to the rear outer side of the material gathering plates.

[0011] Preferably, the outer front part of the polymer plate is fitted with a handle for easy gripping.

[0012] Preferably, the front lower part of the guide plate is provided with a belt conveyor body that conveys longitudinally from back to front.

[0013] Preferably, the vibratory motor body is vertically fixedly installed on the rear bottom surface of the guide plate, and the vibratory motor body and the belt conveyor body do not interfere with each other in space.

[0014] Preferably, each of the disassembly and assembly components includes an L-shaped connecting plate and a U-shaped bracket. The L-shaped connecting plate is fixed to the rear outer side of the material gathering plate, and the rear of the L-shaped connecting plate extends longitudinally backward. Simultaneously, the rear of the L-shaped connecting plates on both sides has lateral limiting holes on their far-away outer end faces. The front of both sides of the vibrating screen body has U-shaped brackets fixed at positions corresponding to the material conveying assembly. The U-shaped brackets on both sides are longitudinally arranged, and their tops are open. The rear of each L-shaped connecting plate is vertically slidably engaged between the corresponding sides of the U-shaped bracket. The far-away outer end faces of the U-shaped brackets on both sides have lateral mounting holes. These mounting holes are through holes, and they are laterally coaxially aligned with the limiting holes on the corresponding sides. Limiting rods are coaxially inserted through these mounting holes in a lateral sliding engagement, and the ends of the limiting rods on both sides are laterally slidably engaged with the corresponding limiting holes.

[0015] Preferably, the outer ends of the limiting rods on both sides, which are far apart from each other, are coaxially fixed with handles. The portion of the limiting rod located between the corresponding handle and the outer side of the U-shaped card seat is coaxially fitted with a spring, and the two ends of the spring are respectively fixedly connected to the corresponding handle and the outer side of the U-shaped card seat.

[0016] Preferably, the mounting holes are all located at half the longitudinal length of the corresponding U-shaped card holder, and the rear bottom surface of the L-shaped connecting plate is in contact with the inner bottom surface of the corresponding U-shaped card holder.

[0017] Preferably, the rear end of each U-shaped card holder is sealed and fixed with a sealing plate, and the rear end face of the L-shaped connecting plate is in close contact with the front end face of the sealing plate.

[0018] In the actual use of the aforementioned inclined vibrating screen, the screen body is equipped with a screen mesh, which divides the interior of the screen body into two screening spaces. This facilitates the separation of ore into ore that meets the particle size requirements and ore that still needs further crushing. The screening operation before crushing is simple and easy to implement. Furthermore, the two layers of material guiding and conveying components are located at the front end of the screen body. Both layers of material guiding and conveying components can gather and collect the ore for outward conveying and prevent discharge congestion. The material guiding and conveying components are flush with the front end of the screen and the bottom end of the vibrating screen body, respectively. The material is gathered and collected by the material-gathering plates on both sides of the material guiding and conveying components, allowing the ore to be smoothly discharged along the guide plates and onto the belt conveyor body for output. This achieves continuous screening of the ore, improving screening efficiency. Simultaneously, the vibration of the vibrating motor body mounted on the bottom surface of the guide plates prevents material accumulation and blockage, further ensuring the ore can be discharged along the guide plates and onto the belt conveyor body. The conveyor body outputs material outwards from the rear. Since the disassembly and assembly components are combined on both sides of the material conveying assembly, the guide plate and the material gathering plate of the material conveying assembly can be detachably fixed to the front of the vibrating screen body through the vertical sliding engagement of the L-shaped connecting plate and the U-shaped bracket, and the horizontal sliding engagement of the limiting rod and the limiting hole. The combination of the guide plate and the material gathering plate of the material conveying assembly at the front of the vibrating screen body is simple and easy to implement, facilitating rapid assembly of the guide plate and the material gathering plate. The material is conveyed outward from the front of the vibrating screen body. Simultaneously, by simply pulling the limiting rod outward from the limiting hole using the handles on both sides, the L-shaped connecting plate can slide vertically out of the U-shaped bracket. This allows the guide plate and the material gathering plate of the material conveying assembly to be detached from the front of the vibrating screen body. The method of separating the guide plate and the material gathering plate from the front of the vibrating screen body is simple and easy to implement, facilitating cleaning, maintenance, and inspection and repair of the vibrating motor body after the guide plate and the material gathering plate are removed.

[0019] The beneficial effects are as follows: 1. The vibrating screen body of this utility model is equipped with a screen, which can divide the interior of the vibrating screen body into two screening spaces. It is convenient to use the two screening spaces to screen out the ore material that meets the particle size requirements and the ore material that still needs to be crushed. The screening operation before crushing the ore material is simple and easy to implement.

[0020] 2. Two layers of material guiding and conveying components are installed at the front end of the vibrating screen body. Both layers of material guiding and conveying components can gather and collect the ore and convey it outward, avoiding discharge congestion. At the same time, the two layers of material guiding and conveying components are flush with the front end of the screen and the front end of the bottom of the vibrating screen body, respectively. Then, by the material gathering plates on both sides of the material guiding and conveying components, the ore can be smoothly discharged outward along the guide plate and fall onto the belt conveyor body for output. This realizes continuous screening of ore and helps to improve the screening efficiency of ore. At the same time, by the vibration of the vibrating motor body installed on the bottom surface of the guide plate, the ore can be prevented from accumulating and congesting on the guide plate, which would lead to discharge blockage. This further ensures that the ore can be discharged outward along the guide plate and fall onto the belt conveyor body for output.

[0021] 3. The material conveying component is equipped with detachable assembly components on both sides. Through the vertical sliding engagement of the L-shaped connecting plate and the U-shaped bracket of the detachable assembly components and the horizontal sliding engagement of the limiting rod and the limiting hole, the guide plate and the material gathering plate of the material conveying component can be detachably fixed to the front of the vibrating screen body. The assembly method of the guide plate and the material gathering plate of the material conveying component at the front of the vibrating screen body is simple and easy to implement, which facilitates the quick assembly of the guide plate and the material gathering plate of the material conveying component at the front of the vibrating screen body for conveying mineral materials outward.

[0022] 4. The L-shaped connecting plate can be vertically slid out of the U-shaped bracket after the limiting rod is pulled out of the limiting hole. This allows the guide plate and the material gathering plate of the material conveying component to be removed from the front of the vibrating screen body. The method of separating the guide plate and the material gathering plate of the material conveying component from the front of the vibrating screen body is simple and easy to achieve. It is convenient to clean and maintain the guide plate and the material gathering plate of the material conveying component after removal, and to inspect and repair the vibrating motor body.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] See Figures 1-9As shown, this utility model provides an inclined vibrating screen, including a vibrating screen body 2. The screening and sliding direction of the vibrating screen body 2 is inclined downward from back to front along the longitudinal direction. A single layer of screen 201 is provided on the vibrating screen body 2 along its own screening and sliding direction. The screen 201 is unfolded and arranged in the inner middle of the vibrating screen body 2, so as to divide the interior of the vibrating screen body 2 into two screening spaces through the screen 201. The advantage of this arrangement is that the mineral material can be screened into mineral material that meets the particle size requirements and mineral material that still needs to be crushed by means of the two screening spaces. The screening operation before crushing the mineral material is simple and easy to implement.

[0037] See Figures 1-6 As shown, the front of the vibrating screen body 2 is provided with two layers of material guiding and conveying components 1, which are flush with the front end of the screen 201 and the bottom end of the vibrating screen body 2, respectively. These components are used to gather and convey the aggregated ore outwards, preventing discharge congestion. Specifically, each material guiding and conveying component 1 includes a guide plate 103 and a gathering plate 101. The guide plates 103 are respectively located at the front end of the screen 201 and the bottom end of the vibrating screen body 2. The guide plates 103 extend outwards at an angle along the screening and sliding direction of the vibrating screen body 2. Gathering plates 101 are vertically extended and fixed to the top of both sides of the guide plates 103. The gathering plates 101 on both sides of the same layer are arranged in a V-shape with the smaller opening at the front. The disassembly and assembly components 3 are fixed to the outer rear of the gathering plates 101. The lower front part of the guide plates 103 is flush with the outer rear part of the material guiding components 101. A belt conveyor body 104 is arranged horizontally in the longitudinal direction, conveying materials from back to front. A vibrating motor body 105 is vertically fixed on the rear bottom surface of the guide plate 103, and the vibrating motor body 105 and the belt conveyor body 104 do not interfere with each other in space. The purpose of this arrangement is that by gathering and aggregating materials on both sides of the material conveying component 1, the ore can be smoothly discharged outward along the guide plate 103 and fall onto the belt conveyor body 104 for output. This realizes continuous screening of ore and helps to improve the screening efficiency of ore. At the same time, by vibrating the vibrating motor body 105 installed on the bottom surface of the guide plate 103, the ore can be prevented from accumulating and clogging on the guide plate 103, which would lead to discharge blockage. This further ensures that the ore can be discharged outward along the guide plate 103 and fall onto the belt conveyor body 104 for output.

[0038] See Figures 1-9As shown, on both sides of the front of the vibrating screen body 2, at positions corresponding to the material conveying components 1, disassembly and assembly components 3 are assembled. The disassembly and assembly components 3 are partially fixed to the side of the material conveying components 1, and the material conveying components 1 are detachably fixed to the front of the vibrating screen body 2 via the disassembly and assembly components 3. Specifically, each disassembly and assembly component 3 includes an L-shaped connecting plate 303 and a U-shaped bracket 302. An L-shaped connecting plate 303 is fixed to the rear outer side of the material gathering plate 101, and the rear of the L-shaped connecting plate 303 extends longitudinally backward. Simultaneously, the rear of the L-shaped connecting plates 303 on both sides are at their outer ends that are far apart from each other. Each side of the vibrating screen body 2 has a limiting hole 308 opened laterally. U-shaped brackets 302 are fixed at the front of both sides of the vibrating screen body 2 at positions corresponding to the material conveying component 1. The U-shaped brackets 302 on both sides are longitudinally arranged, and their tops are open. Simultaneously, the rear of the L-shaped connecting plate 303 is vertically slidably engaged between the two sides of the corresponding U-shaped bracket 302. The outer end faces of the U-shaped brackets 302 on both sides, which are far apart from each other, have mounting holes 306 opened laterally. All mounting holes 306 are through holes, and they are all horizontally coaxially aligned with the limiting holes 308 on the corresponding sides. 06. Limiting rods 307 are coaxially inserted in a lateral sliding fit. The ends of the limiting rods 307 on both sides that are close to each other are coaxially slidingly fitted with the corresponding limiting holes 308. The outer ends of the limiting rods 307 on both sides that are far apart from each other are coaxially fixed with handles 304. The portion of the limiting rod 307 located between the corresponding handle 304 and the outer side of the U-shaped card seat 302 is coaxially fitted with springs 305 with clearance. The two ends of the springs 305 are respectively fixedly connected to the outer side of the corresponding handle 304 and the U-shaped card seat 302. The purpose of this arrangement is to allow for easy connection between the L-shaped connecting plate 303 and the U-shaped card seat 302 through disassembly and assembly. The vertical sliding engagement of the seat 302 and the horizontal sliding engagement of the limiting rod 307 and the limiting hole 308 allow the guide plate 103 and the material gathering plate 101 of the material conveying component 1 to be detachably fixed to the front of the vibrating screen body 2. At the same time, by simply pulling the limiting rod 307 out of the limiting hole 308, the L-shaped connecting plate 303 can be vertically slid out of the U-shaped seat 302. This allows the guide plate 103 and the material gathering plate 101 of the material conveying component 1 to be detached from the front of the vibrating screen body 2. The combination and disassembly of the guide plate 103 and the material gathering plate 101 of the material conveying component 1 at the front of the vibrating screen body 2 is simple and easy to implement.

[0039] See Figures 1-9As shown, the vibrating screen body 2, the material conveying assembly 1, and the disassembly and assembly assembly 3 have been optimized as follows. Specifically, the vibrating screen body 2 is an eccentric vibrating screener, so that the vibrating screen body 2 itself has efficient and stable mineral screening capabilities. Optionally, handles 102 are fixed to the front outer side of the material gathering plate 101 for easy gripping, so that the material gathering plate 101, the material guide plate 103, and the vibrating motor body 105 can be lifted and moved together by applying force through the handles 102. Alternatively, the mounting holes 306 are all located at half the longitudinal length of the corresponding U-shaped bracket 302, and the rear bottom surface of the L-shaped connecting plate 303 is in contact with the inner bottom surface of the corresponding U-shaped bracket 302. With this arrangement, after the L-shaped connecting plate 303 and the U-shaped bracket 302 are engaged, the contact between the rear bottom surface of the L-shaped connecting plate 303 and the inner bottom surface of the corresponding U-shaped bracket 302 can prevent the L-shaped connecting plate 303 from shifting or moving. Furthermore, the rear end of the U-shaped card holder 302 is sealed and fixed with a sealing plate 301, and the rear end face of the L-shaped connecting plate 303 is in close contact with the front end face of the sealing plate 301. This arrangement firstly facilitates a clear indication when the L-shaped connecting plate 303 and the U-shaped card holder 302 are properly engaged, as the rear end face of the L-shaped connecting plate 303 is in close contact with the front end face of the sealing plate 301. At the same time, by having the rear end of the L-shaped connecting plate 303 abut against the front of the sealing plate 301, it can further prevent the L-shaped connecting plate 303 from shifting or moving.

[0040] With the above structure, specifically in the actual use of the vibrating screen body 2, since the vibrating screen body 2 is equipped with a screen 201, the interior of the vibrating screen body 2 can be divided into two screening spaces through the screen 201. This facilitates the separation of ore into ore that meets the particle size requirements and ore that still needs further crushing using the two screening spaces. The screening operation before ore crushing is simple and easy to implement. Furthermore, since two layers of material guiding and conveying components 1 are set at the front end of the vibrating screen body 2, and both layers of material guiding and conveying components 1 can gather and collect the ore and convey it outwards while avoiding discharge congestion, the two layers of material guiding and conveying components 1 are respectively connected to the screen. The front end of the screen 201 is flush with the front end of the bottom of the vibrating screen body 2. The material is then gathered and collected by the material-gathering plates 101 on both sides of the material-guiding and conveying assembly 1, allowing the ore to be smoothly discharged outwards along the guide plate 103 and onto the belt conveyor body 104 for further output. This achieves continuous screening of the ore, improving screening efficiency. Simultaneously, the vibration of the vibrating motor body 105 mounted on the bottom surface of the guide plate 103 prevents ore from accumulating and clogging on the guide plate 103, further ensuring that the ore can be discharged outwards along the guide plate 103 and onto the belt conveyor body 104. The material is output outwards. Since both sides of the material conveying component 1 are equipped with detachable assembly components 3, the L-shaped connecting plate 303 of the detachable assembly component 3 slides vertically with the U-shaped bracket 302, and the limiting rod 307 slides laterally with the limiting hole 308. This allows the guide plate 103 and the material gathering plate 101 of the material conveying component 1 to be detachably fixed to the front of the vibrating screen body 2. The assembly method of the guide plate 103 and the material gathering plate 101 at the front of the vibrating screen body 2 is simple and easy to implement, facilitating the quick assembly of the guide plate 103 and the material gathering plate 101 onto the vibrating screen body 2. The front part of the screen body 2 is used to convey mineral materials outward. At the same time, by simply holding the handles 304 on both sides and pulling the limiting rods 307 out of the limiting holes 308, the L-shaped connecting plate 303 can be vertically slid out of the U-shaped bracket 302. This allows the guide plate 103 and the material gathering plate 101 of the material conveying component 1 to be removed from the front part of the vibrating screen body 2. The method of separating the guide plate 103 and the material gathering plate 101 of the material conveying component 1 from the front part of the vibrating screen body 2 is simple and easy to achieve. It is convenient to clean and maintain the guide plate 103 and the material gathering plate 101 of the material conveying component 1 after removal, and to inspect and repair the vibrating motor body 105.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
