Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a feeding equipment for crushing and screening non-metallic minerals. Background Technology

[0002] In the non-metallic mineral processing industry, efficient crushing, screening, and feeding processes are crucial. Traditional feeding equipment has several shortcomings. Firstly, most equipment has a fixed feeding height, failing to flexibly adapt to the material height requirements of different processing steps, leading to cumbersome material transfer processes and impacting production efficiency. Secondly, its screening and crushing functions are often independent, lacking synergy, making it prone to problems such as uneven particle size and incomplete impurity separation when materials flow between different devices. Furthermore, some existing equipment has complex structures, is difficult to operate and maintain, increasing labor costs and easily causing production stoppages due to malfunctions. Moreover, it lacks versatility when dealing with different types and properties of non-metallic minerals, making it difficult to meet diverse production needs. Therefore, the development of a new type of feeding equipment for non-metallic mineral crushing and screening is urgently needed. It must possess flexible height adjustment capabilities to achieve efficient coordinated screening and crushing operations, and have a simple structure that is easy to operate and maintain, thereby improving production efficiency, reducing production costs, and meeting the industry's increasingly diverse production demands.

[0003] Traditional feeding equipment for non-metallic mineral crushing and screening has not solved the problem of easily screening and crushing metal ore materials with a simple structure. Therefore, we propose a feeding device for non-metallic mineral crushing and screening. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that facilitate the screening, crushing, feeding, and transport of metal ore materials using simple structures, and to propose a feeding device for crushing and screening non-metallic minerals.

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

[0006] A feeding device for crushing and screening non-metallic minerals includes a fixed base and a fixing component. The fixing component is fixedly connected to the top of the fixed base. The fixing component includes a device mounting shell. A feeding funnel is fixedly connected to one side of the upper surface of the device mounting shell. Two discharge ports are opened on the side surface of the device mounting shell near the feeding funnel. Two V-shaped frames are fixedly connected to the lower end of the two discharge ports on opposite sides. Two filter screens are fixedly connected to the middle of the two V-shaped frames by a group of fixing bolts. An L-shaped support frame is fixedly connected to the lower surface of the inner wall of the device mounting shell at the bottom of the two V-shaped frames.

[0007] As a further embodiment of this utility model: a controller is fixedly connected to the surface of the device mounting shell on one side of the two discharge ports; two cylindrical hollow sleeves are fixedly connected to the inner wall of the mounting shell on the side of the L-shaped support frame away from the inner wall of the device mounting shell; and two fixed sleeve columns are fixedly connected to the upper surface of the inner wall of the device mounting shell on the side of the two cylindrical hollow sleeves away from the L-shaped support frame.

[0008] By fixing the controller to the surface of the device's mounting housing, a convenient centralized control area is provided for operators, enabling flexible adjustment of the operating status of various equipment functions and accurately meeting different work requirements.

[0009] A hollow cylindrical sleeve is connected at a specific position on the L-shaped support frame to provide reliable support and rotation space for the support column, thereby ensuring the smooth rotation of the support column. A fixed sleeve is connected above the hollow cylindrical sleeve to provide a stable installation base for the vertically mounted hydraulic cylinder, thereby providing precise guidance for the vertical movement of the movable sleeve and ensuring stable lifting and precise positioning of the movable sleeve.

[0010] As a further embodiment of this utility model: two vertically mounted hydraulic cylinders are fixedly installed inside the two fixed sleeves, and two movable sleeves are fixedly connected to the upper ends of the two vertically mounted hydraulic cylinders, and a U-shaped frame is fixedly connected to the top of the two movable sleeves.

[0011] The vertically mounted hydraulic cylinder is fixed inside the fixed sleeve. Through the extension and retraction of the hydraulic cylinder, the movable sleeve is driven to rise and fall vertically within the fixed sleeve, achieving the purpose of flexibly and accurately adjusting the height of the U-shaped frame. The movable sleeve is fixedly connected to the U-shaped frame, effectively transmitting the power of the hydraulic cylinder to the U-shaped frame and connected components, so as to adjust the height of the transport and installation frame according to actual working needs and adapt to different material loading height requirements.

[0012] As a further embodiment of this utility model: two supporting rotating columns are rotatably connected inside the two cylindrical hollow sleeves and the U-shaped frame, two sets of mounting rings are rotatably connected to the top of the two supporting rotating columns, and two sets of support rods are fixedly connected to the top of the two sets of mounting rings.

[0013] The rotating support column is rotatably connected within the cylindrical hollow sleeve and U-shaped frame, providing a stable rotation axis for adjusting the angle of the transport and installation frame, thus enabling the transport and installation frame to flexibly change its tilt angle. The rotating support column is connected to the support rod through the mounting ring, which converts the rotation of the rotating support column into precise adjustment power for the angle of the transport and installation frame, thereby meeting the requirements of different loading positions and angles and improving the accuracy of loading.

[0014] As a further embodiment of this utility model: a transport mounting frame is fixedly connected to the top of the two sets of support rods, and a trapezoidal crushing shell is fixedly connected to the top of the L-shaped support frame. A discharge port is opened at the lower end of the trapezoidal crushing shell near the transport mounting frame. Two motors are evenly fixedly connected inside the transport mounting frame and on one side of the trapezoidal crushing shell. Two sets of drive pulleys are rotatably connected to the output ends of the two motors.

[0015] The support rod is fixed to the transport and installation frame, providing stable support and transmitting angle adjustment power to ensure the stability and adjustability of the transport and installation frame during operation. The L-shaped support frame connects to the trapezoidal crushing shell, providing a solid load-bearing structure for crushing operations and ensuring a stable and reliable crushing process. A discharge port is opened at a specific location on the trapezoidal crushing shell to allow the crushed material to flow smoothly to the transport and installation frame, optimizing the material transfer path and improving work efficiency. A motor is installed on one side of the transport and installation frame and the trapezoidal crushing shell and connected to a drive pulley. The motor drives the drive pulley to rotate, providing power for material crushing and transfer, enabling related components to work together to complete material handling and feeding tasks.

[0016] As a further embodiment of this utility model: the two sets of driving pulleys are rotatably connected to multiple sets of driven pulleys on one side via two sets of transmission belts, and multiple rotating columns are rotatably connected to the middle of the two sets of driving pulleys and the multiple sets of driven pulleys.

[0017] The driving pulley is connected to the driven pulley via a transmission belt, which efficiently transmits the power of the driving pulley to the driven pulley, enabling multiple driven pulleys to rotate synchronously and ensuring stable power transmission. The driving pulley and driven pulley are rotatably connected to the rotating column, which converts the rotation of the pulleys into the rotation of the rotating column, providing a power transmission channel for the operation of the crushing wheel and the transmission track, and ensuring the normal operation of all functions of the equipment.

[0018] As a further embodiment of this utility model: a plurality of crushing wheels are fixedly connected to the surface of the rotating column installed inside the trapezoidal crushing shell, and a transmission track is rotatably connected to the surface of the rotating column installed inside the transport mounting frame.

[0019] A crushing wheel is fixed on a rotating column inside a trapezoidal crushing shell. The rotation of the column drives the crushing wheel to rotate at high speed, effectively crushing the ore falling into the trapezoidal crushing shell and reducing the ore particle size to meet the feeding requirements, thereby improving the applicability of the material. A transmission track is rotatably connected to the rotating column inside the transport installation frame. The rotation of the column drives the transmission track to operate, thereby smoothly transporting the crushed material to the designated location for feeding, completing the material feeding work and ensuring the continuity of the production process.

[0020] Compared with the prior art, this utility model provides a feeding device for crushing and screening non-metallic minerals, which has the following beneficial effects:

[0021] 1. In this utility model, when using the equipment, the operator feeds the non-metallic mineral material to be processed into the feeding funnel. Under the influence of gravity, the material falls vertically to the top of the filter screen, at which point two roof-shaped filter screens installed inside the V-shaped frame begin to function. This roof-shaped filter screen design prevents larger ore materials from passing through the mesh, thus intercepting them on the filter screen surface and achieving the purpose of preliminary screening of the ore. Subsequently, the larger ore materials slide down the filter screen and are discharged from the two discharge ports.

[0022] Smaller ore particles slide across the top of the filter screen and fall directly into the trapezoidal crushing shell through the mesh. A motor on one side of the crushing shell starts, driving the drive pulley to rotate. The drive pulley is connected to the driven pulley via a transmission belt, transmitting power to the driven pulley and causing it to rotate as well. Since both the drive and driven pulleys are rotatably connected to a rotating column, the rotation of the driven pulley further drives the rotating column. The crushing wheel, fixed to the surface of the rotating column inside the trapezoidal crushing shell, rotates along with the column. Through the high-speed rotation of the crushing wheel and its contact and compression with the ore, the ore falling into the crushing shell is crushed, reducing its particle size to meet the particle size requirements for subsequent feeding.

[0023] After the ore is crushed within the trapezoidal crushing shell, guided by the shape of the shell, it falls freely onto the drive belt from the discharge port near the lower end of the transport mounting frame. The motor inside the transport mounting frame starts, and its output drives the drive pulley to rotate. The drive pulley, through a drive belt, drives the driven pulley to rotate, which in turn drives the rotating column inside the transport mounting frame. Since the drive belt is rotatably connected to the surface of the rotating column, the rotation of the rotating column drives the drive belt, thus conveying the crushed material to the output end of the drive belt for loading.

[0024] In summary, by using a filter screen to screen the ore, the trapezoidal crushing shell structure to crush the ore, and the transmission belt to transport the crushed material, this device achieves the purpose of screening metal ore materials and crushing, feeding, and transporting them with a simple structure.

[0025] 2. In this utility model, when the equipment is ready to run, the user operates the controller and issues a command to start the vertically mounted hydraulic cylinder inside the fixed sleeve. The pressure change of the hydraulic oil inside the cylinder pushes the piston rod upward, thereby raising the movable sleeve that is fixedly connected to it. Since the top of the movable sleeve is fixedly connected to the U-shaped frame, the rise of the movable sleeve then drives the U-shaped frame to rise synchronously. Furthermore, because the U-shaped frame is rotatably connected to the supporting rotating column, and the supporting rotating column is connected to the support rod through a mounting ring, with the top of the support rod fixedly connected to the transport mounting frame, the rise of the U-shaped frame, through this series of connecting structures, ultimately drives the transport mounting frame to rise, achieving the purpose of adjusting the transport mounting frame to the required loading height, meeting the height requirements of different working scenarios.

[0026] Two hollow cylindrical sleeves are fixed to the inner wall of the mounting housing on the side of the L-shaped support frame away from the inner wall of the device mounting housing, and a support column is rotatably connected inside them. Through this design, the hollow cylindrical sleeves provide stable support and rotation space for the support column, ensuring that the support column can rotate flexibly inside them, thus providing a stable rotation axis for adjusting the angle of the transport mounting frame.

[0027] Meanwhile, the U-shaped frame also features rotatable support columns, further enhancing their stability and rotational flexibility. Both sets of support columns have mounting rings rotatably connected to their tops, which in turn connect to the support rods. This combined design allows the user to precisely adjust the tilt angle of the transport mounting frame when needed, by rotating the support rods and causing the support columns to rotate within the hollow cylindrical sleeve and U-shaped frame. This enables the transport mounting frame to better adapt to different loading positions and angle requirements.

[0028] This combination of cylindrical hollow sleeve and supporting rotating column, along with the function of hydraulic cylinder driving the transport and installation frame to rise, allows the transport and installation frame to not only rise and fall vertically, but also adjust its angle horizontally, fully meeting the loading needs of different heights and angles.

[0029] In summary, by using hydraulic cylinders to lift the transport and installation frame and combining the design of a cylindrical hollow sleeve and a supporting rotating column, the device achieves its purpose of easily adapting to material loading at different heights.

[0030] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0038] Example: Reference Figures 1 to 4A feeding device for crushing and screening non-metallic minerals includes a fixed base 1 and a fixed component 2. The fixed base 1 is fixedly connected to the top of the fixed component 2. The fixed component 2 includes a device mounting shell 201. A feeding funnel 202 is fixedly connected to one side of the upper surface of the device mounting shell 201. Two discharge ports 203 are opened on the side surface of the device mounting shell 201 near the feeding funnel 202. Two V-shaped frames 204 are fixedly connected to the lower end of the opposite side of the two discharge ports 203. Two filter screens 206 are fixedly connected to the middle of the two V-shaped frames 204 by a group of fixing bolts 205. An L-shaped support frame 207 is fixedly connected to the lower surface of the inner wall of the device mounting shell 201 at the bottom of the two V-shaped frames 204.

[0039] A controller 3 is fixedly connected to the surface of the device mounting shell 201 located on one side of the two discharge ports 203. Two cylindrical hollow sleeves 208 are fixedly connected to the inner wall of the mounting shell on the side of the L-shaped support frame 207 away from the inner wall of the device mounting shell 201. Two fixed sleeve posts 209 are fixedly connected to the upper surface of the inner wall of the device mounting shell 201 away from the L-shaped support frame 207.

[0040] Two vertically mounted hydraulic cylinders 210 are fixedly installed inside the two fixed sleeves 209. Two movable sleeves 211 are fixedly connected to the upper ends of the two vertically mounted hydraulic cylinders 210. A U-shaped frame 212 is fixedly connected to the top of the two movable sleeves 211.

[0041] Two supporting rotating columns 213 are rotatably connected inside the two cylindrical hollow sleeves 208 and the U-shaped frame 212. Two sets of mounting rings 214 are rotatably connected to the top of each of the two supporting rotating columns 213. Two sets of support rods 215 are fixedly connected to the top of each of the two sets of mounting rings 214.

[0042] The top of the two sets of support rods 215 is fixedly connected to a transport mounting frame 216, and the top of the L-shaped support frame 207 is fixedly connected to a trapezoidal crushing shell 217. The lower end of the trapezoidal crushing shell 217 near the transport mounting frame 216 has a discharge port 218. Two motors 219 are evenly fixedly connected inside the transport mounting frame 216 and on one side of the trapezoidal crushing shell 217. The output ends of the two motors 219 are rotatably connected to two sets of drive pulleys 220.

[0043] Both sets of driving pulleys 220 are rotatably connected to multiple sets of driven pulleys 222 on one side via two sets of transmission belts 221, and multiple rotating columns 223 are rotatably connected to the middle of both sets of driving pulleys 220 and multiple sets of driven pulleys 222.

[0044] Multiple crushing wheels 224 are fixedly connected to the surface of the rotating column 223 installed inside the trapezoidal crushing shell 217, and a transmission track 225 is rotatably connected to the surface of the rotating column 223 installed inside the transport mounting frame 216.

[0045] In this embodiment, in the fixing component 2, the controller 3 is fixedly connected to the surface of the device mounting housing 201 on one side of the two discharge ports 203. This arrangement provides operators with a centralized control center for the equipment, facilitating unified control of various functional modules and meeting the precise control requirements of different working scenarios.

[0046] Two cylindrical hollow sleeves 208 are fixedly connected to the inner wall of the mounting housing 201 on the side of the L-shaped support frame 207 away from the inner wall of the mounting housing 201. Simultaneously, two fixed sleeve columns 209 are fixedly connected to the upper surface of the inner wall of the mounting housing 201 on the side of the two cylindrical hollow sleeves 208 away from the L-shaped support frame 207. Through this arrangement, the cylindrical hollow sleeves 208 provide stable support and rotation space for the supporting rotating column 213, ensuring that the supporting rotating column 213 can rotate smoothly. The fixed sleeve columns 209 provide a reliable installation position for the vertically mounted hydraulic cylinder 210, achieving precise guidance for the vertical movement of the movable sleeve column 211, ensuring the stability and precise positioning of the movable sleeve column 211 during its lifting process.

[0047] Two vertically mounted hydraulic cylinders 210 are fixedly installed inside two fixed sleeves 209. The upper ends of the hydraulic cylinders are fixedly connected to two movable sleeves 211, and the tops of the movable sleeves 211 are connected to the U-shaped frame 212. By changing the hydraulic oil pressure inside the hydraulic cylinders, the piston rods are pushed to extend and retract, thereby driving the movable sleeves 211 to rise and fall vertically within the fixed sleeves 209, and thus driving the U-shaped frame 212 to rise and fall synchronously. Through this height adjustment mechanism, the height of the U-shaped frame 212 and the connected transport and mounting frame 216 can be flexibly and precisely adjusted according to actual working needs to adapt to different loading height requirements.

[0048] Two supporting columns 213 are rotatably connected inside both the two cylindrical hollow sleeves 208 and the U-shaped frame 212. Two sets of mounting rings 214 are rotatably connected to the top of each supporting column 213, and two sets of support rods 215 are connected to the top of each mounting ring 214. Through this connection, the cylindrical hollow sleeves 208 and the U-shaped frame 212 provide a fulcrum for the supporting columns 213, allowing them to rotate flexibly. The supporting columns 213 are connected to the support rods 215 via the mounting rings 214, thus converting the rotation of the supporting columns 213 into power to adjust the angle of the transport mounting frame 216. This allows for precise adjustment of the tilt angle of the transport mounting frame 216, meeting the requirements of different loading positions and angles.

[0049] Two sets of support rods 215 are fixedly connected to the top of the transport mounting frame 216, and the L-shaped support frame 207 is fixedly connected to the top of the trapezoidal crushing shell 217. Through this connection, the support rods 215 provide stable support for the transport mounting frame 216 and transmit angle adjustment power, ensuring the stability and adjustability of the transport mounting frame 216 during operation; the L-shaped support frame 207 provides a solid load-bearing structure for the trapezoidal crushing shell 217, ensuring stable crushing operations. Simultaneously, a discharge port 218 is opened at the lower end of the trapezoidal crushing shell 217 near the transport mounting frame 216, allowing the crushed material to flow smoothly to the transport mounting frame 216, optimizing the material transport path, improving the overall equipment efficiency, and achieving the purpose of the fixed component 2 supporting and functionally coordinating the key components of the equipment.

[0050] Working principle: When using this non-metallic mineral crushing and screening feeding equipment, the user first moves the entire equipment to the relevant work site using the fixed base 1. This method of movement places the equipment in a suitable work location, thus preparing the space for subsequent feeding operations.

[0051] Subsequently, the user operates the controller 3, which, through commands issued by the controller 3, controls the vertically mounted hydraulic cylinder 210 inside the fixed sleeve 209. Upon receiving the command, the vertically mounted hydraulic cylinder 210 begins operation, extending its piston rod to raise the movable sleeve 211, which in turn raises the transport mounting frame 216, which is fixedly connected to the top of the movable sleeve 211. Through this series of actions, the transport mounting frame 216 is raised to the required loading height, achieving the initial positioning of the loading height.

[0052] After initial positioning, the user manually rotates and pushes the support rod 215. Since the support rod 215 is connected to the mounting ring 214 and the support rotating column 213, this operation causes the support rotating column 213 to rotate inside the cylindrical hollow sleeve 208 and the U-shaped frame 212. Simultaneously, the cylindrical hollow sleeve 208 and the U-shaped frame 212 fix and guide the support rotating column 213, allowing it to rotate stably. The rotation of the support rotating column 213 enables a more precise adjustment of the angle of the transport mounting frame 216, ensuring that the loading angle of the transport mounting frame 216 meets the actual working requirements.

[0053] After adjusting the transport frame 216, workers feed the non-metallic mineral materials to be screened from the top of the feeding funnel 202. After feeding, the materials fall vertically under gravity onto the top of the filter screen 206. Because the two filter screens 206 are installed inside the two V-shaped frames 204 in a roof-like design, larger ore materials cannot pass through the filter screens 206 and fall from the two discharge ports 203; smaller materials slide directly into the trapezoidal crushing shell 217 as they slide on top of the filter screens 206. This design achieves preliminary screening of the materials, separating materials of different particle sizes.

[0054] After smaller materials fall into the trapezoidal crushing shell 217, the user operates the controller 3 again to open the entire device. At this time, the motor 219 on one side of the trapezoidal crushing shell 217 starts, and the output shaft of the motor 219 rotates, driving the drive pulley 220 to rotate. The drive pulley 220 is connected to the driven pulley 222 via the transmission belt 221, thus driving the driven pulley 222 to rotate together. Since both the drive pulley 220 and the driven pulley 222 are rotatably connected to the middle of the rotating column 223, the rotation of the driven pulley 222 in turn drives the rotating column 223 to rotate, and the crushing wheel 224 fixed on the surface of the rotating column 223 also rotates accordingly. Through this series of transmissions, the crushing wheel 224 is used to crush the ore falling into the trapezoidal crushing shell 217, thereby reducing the ore particle size and meeting the particle size requirements for subsequent feeding.

[0055] After the ore is crushed, guided by the trapezoidal crushing shell 217, it falls freely onto the transmission track 225, whose feeding angle has been adjusted beforehand. The motor 219 inside the transport mounting frame 216 starts, and its output drives the drive pulley 220 to rotate. The drive pulley 220, through the transmission belt 221, drives the driven pulley 222 to rotate. The driven pulley 222 then drives the rotating column 223 inside the transport mounting frame 216 to rotate, thereby driving the transmission track 225. Through the operation of the transmission track 225, the crushed metal ore is transported to its output end, completing the feeding process and providing suitable material for subsequent processing.

[0056] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
