Description

Technical Field

[0001] The invention belongs to the technical field of screening equipment, in particular to a multifunctional vibrating screen. Background Art

[0002] In modern industrial production, vibrating screens are used as efficient screening equipment in many fields such as ore, coal, grain, medicine, and chemical industry. However, traditional vibrating screens have the following significant problems during use.

[0003] The surface of the existing screen is flat. During screening, the material moves upward horizontally, causing the material on the edge of the screen to be collided and separated from the screen surface and mixed with the screened material, resulting in the need to frequently stop the machine to clean the material that has separated from the screen. In addition, during the screening process of materials, the existing vibrating screen equipment will get stuck in the mesh holes of the screen, resulting in a reduction in the effective screening area of ​​the screen. Therefore, it is necessary to frequently stop the machine to clean the material stuck in the screen, which not only reduces production efficiency, but also increases the complexity of operation and production costs. In addition, screens of different diameters have different screening requirements for different materials. Existing equipment often needs to frequently replace screens with different mesh diameters, which is not only time-consuming and labor-intensive, but also leads to low screening efficiency and increased production costs. Summary of the invention

[0005] In order to achieve the above-mentioned objectives, the present invention provides the following technical solutions: a multifunctional vibrating screen comprises a mounting plate, the lower surface of the mounting plate is symmetrically fixedly mounted with four supporting feet, the upper surface of the mounting plate is symmetrically fixedly mounted with four guide rails, the middle portion of the guide rail is provided with a trapezoidal groove, the middle portion of the trapezoidal groove is slidably sleeved with a plurality of mounting frames, the middle portion of the mounting frame is provided with a rectangular groove, the middle portion of the rectangular groove is slidably sleeved with a wire clamping mechanism, a push block is slidably sleeved between two adjacent mounting frames, both sides of the guide rail are fixedly sleeved with fixed columns, a sleeve is fixedly mounted on a side of the fixing column close to the mounting frame, a second elastic member is fixedly mounted on a side of the inner cavity of the sleeve close to the fixing column, a clamping rod is fixedly mounted on an end of the second elastic member away from the fixing column, the clamping rod is slidably sleeved with the sleeve, the clamping rod slides against adjacent mounting frames, and a driving mechanism is provided between the plurality of supporting feet, the wire clamping mechanism and the push blocks.

[0006] Preferably, the wire clamping mechanism includes a mounting block, which is slidably connected to the rectangular groove, a mounting hole is opened on the upper portion of the mounting block, a guide column is fixedly connected to the side of the mounting hole close to the center of the mounting plate, a first elastic member is fixedly installed on one side of the guide column, a wire plug is fixedly installed on one side of the first elastic member, the wire plug is slidably connected to the mounting hole, a mesh is fixedly installed on the middle part of the wire plug, and the mesh is slidably connected to the guide column.

[0007] Preferably, the driving mechanism includes a telescopic rod, which is fixedly mounted on the bottom of the supporting foot and fixedly sleeved with the mounting plate. A connecting block is fixedly mounted on the telescopic end of the telescopic rod, a connecting rail is fixedly mounted between the inner sides of two adjacent connecting blocks, and a ladder groove is provided in the middle of the connecting rail.

[0008] Preferably, the mounting block and the pushing block are slidably sleeved with the ladder groove.

[0009] Preferably, a discharge port is provided in the middle of the mounting plate, and the contact surface between the mounting frame and the guide rail is a smooth surface.

[0010] Preferably, the shape of the mounting frame is trapezoidal, the shape of the push block is trapezoidal, and the contact surface between the push block and the mounting frame is a smooth surface.

[0011] Preferably, the contact surface between the mounting block and the rectangular groove is a smooth surface.

[0012] Preferably, the mounting block and the rectangular groove adopt a high-precision transition fit.

[0013] Preferably, the guide column is made of a high-hardness material, and the contact surfaces of the mounting block and the push block with the ladder groove are all smooth surfaces.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention starts the telescopic rod, so that the driving mechanism drives the wire clamping mechanism and the push block to move downward. At this time, since the shape of the mounting frame is an inverted trapezoid and the shape of the push block is a trapezoid, the push block moves downward and separates from the mounting frame. The second elastic member pushes the clamping rod to squeeze the mounting frame to move in the direction of the push block and fit the push block, so that the distance between multiple mounting frames is constantly approached. The multiple mounting frames drive multiple meshes to approach each other through the wire clamping mechanism slidably sleeved therewith. When the telescopic end of the telescopic rod moves to the bottom, the diameter of the screen formed by the multiple meshes reaches the minimum. Then, the material to be screened is placed above the screen. The material squeezes the mesh wires that constitute the screen to become concave downward, and the mesh wires pull the wire plug fixedly connected thereto to squeeze the first elastic member to move in the direction of the guide column, thereby making the middle part of the screen composed of multiple mesh wires concave downward, and causing the material to move toward the middle part of the middle part of the screen. As a result, when the screen pushes the material to move upward and away from the screen, the curved surface formed by the screen pushes the material on its surface to move upward, and the material moves toward the middle above the screen, thereby preventing the material from falling off the screen surface when it falls downward due to gravity.

[0016] 2. In the present invention, when the material is placed on the screen surface where the screen diameter is the smallest, the telescopic rod is started again, the telescopic end of the telescopic rod accelerates to move upward, the driving mechanism drives the wire clamping mechanism and the push block to move upward, the mounting frame squeezes the push block to move to both sides thereof, so that the multiple mounting frames drive the multiple wire clamping mechanisms to move away from each other, and the multiple wire clamping mechanisms drive the multiple mesh wires to move away from each other, so that the diameter of the screen formed by the multiple mesh wires is continuously increased, the mounting frame squeezes the second elastic member through the clamping rod to contract, and at this time the screen accelerates to push the material above it to accelerate to move upward, and when the telescopic end of the telescopic rod accelerates to move upward to When the screen reaches the diameter required for screening the material, the telescopic end of the telescopic rod begins to decelerate sharply and move upward. At this time, the material on the upper surface of the screen maintains the original speed and moves upward to separate from the screen under the action of inertia. At this time, the diameter of the screen slowly increases, so that the material blocked in the mesh of the screen is separated from the mesh of the screen and moves upward, thereby achieving timely and rapid removal of the material stuck in the mesh of the screen without affecting the normal screening of the material by the screen, overcoming the problem of the prior art that the material stuck in the screen needs to be removed by a brush or the like, and the efficiency of material screening is improved.

[0017] 3. In the present invention, when the material blocked in the mesh is separated from the screen, the telescopic end of the telescopic rod rapidly moves downward to the diameter of the material required for screening, and the telescopic rod stops moving, so that the screen is fixed to the screening position. At this time, the material moving upward due to inertia moves downward due to gravity and collides with the screen. At this time, the material smaller than the mesh diameter falls under the screen, and the telescopic end of the telescopic rod then moves downward to reset, thereby realizing efficient screening of the material. In addition, when the present invention is used, according to the requirements of the material screening size, by controlling the position when the telescopic end of the telescopic rod starts to decelerate sharply and move upward and the stop position when the telescopic end of the telescopic rod rapidly moves downward to the diameter required for screening of the material, the diameter of the screen can be quickly adjusted when the screen is screening the material, thereby realizing indirect replacement of the screen, solving the problems that the existing equipment needs to be shut down to replace the screen and needs to provide a large number of screens with different diameters, resulting in low screening efficiency and increased production costs.

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 6 As shown, an embodiment of the present invention provides a multifunctional vibrating screen, including a mounting plate 1, a discharge port is provided in the middle of the mounting plate 1, so as to facilitate the subsequent collection of screened materials, four supporting feet 2 are symmetrically fixedly installed on the lower surface of the mounting plate 1, and four guide rails 3 are symmetrically fixedly installed on the upper surface of the mounting plate 1, a trapezoidal groove is provided in the middle of the guide rail 3, and a plurality of mounting brackets 4 are slidably sleeved in the middle of the trapezoidal groove. By setting the trapezoidal groove, the guide rail 3 limits the up and down displacement of the mounting bracket 4 while preventing the mounting bracket 4 from shaking up and down, thereby improving the stability of the mounting bracket 4, and the contact surface between the mounting bracket 4 and the guide rail 3 is a smooth surface, thereby reducing the friction resistance when the mounting bracket 4 moves along the trapezoidal groove of the guide rail 3, and reducing the load of the telescopic rod 1101 when the driving mechanism 11 pushes the mounting bracket 4 to move through the push block 6, a rectangular groove 401 is provided in the middle of the mounting bracket 4, a wire clamping mechanism 5 is slidably sleeved in the middle of the rectangular groove 401, and a push block 6 is slidably sleeved between two adjacent mounting brackets 4. The contact surface between the push block 6 and the mounting frame 4 is a smooth surface, thereby reducing the friction resistance when the push block 6 moves upward and pushes the mounting frame 4 to move away from it, reducing the load of the telescopic rod 1101 when the driving mechanism 11 pushes the mounting frame 4 to move through the push block 6, the shape of the mounting frame 4 is a trapezoid, and the shape of the push block 6 is a trapezoid, so that when the push block 6 moves upward, it can push the mounting frame 4 slidably sleeved with it to move to both sides thereof, thereby allowing the mounting frame 4 to increase the diameter of the screen formed by the mesh through the wire clamping mechanism 5, and both sides of the guide rail 3 are fixedly sleeved with fixed columns 7, and the fixed column 7 is fixedly installed with a sleeve 8 on one side of the fixed column 7 close to the mounting frame 4, and a second elastic member 9 is fixedly installed on the side of the inner cavity of the sleeve 8 close to the fixed column 7, and a clamping rod 10 is fixedly installed on the end of the second elastic member 9 away from the fixed column 7, and the clamping rod 10 is slidably sleeved with the sleeve 8, and the clamping rod 10 slides against the adjacent mounting frame 4, and a driving mechanism 11 is provided between the multiple supporting feet 2, the wire clamping mechanism 5 and the push block 6.

[0028] like Figures 1 to 6As shown, the wire clamping mechanism 5 includes a mounting block 501, and the mounting block 501 is slidably sleeved with the rectangular groove 401. The contact surface between the mounting block 501 and the rectangular groove 401 is a smooth surface. The mounting block 501 and the rectangular groove 401 adopt a high-precision transition fit, thereby reducing the friction resistance when the mounting block 501 slides up and down along the rectangular groove 401, and at the same time preventing the wire clamping mechanism 5 from shaking left and right, causing the diameter of the screen formed by the mesh wire clamped therein to increase uncontrollably, resulting in reduced screening accuracy. A mounting hole is opened on the upper part of the mounting block 501, and a guide column 502 is fixedly sleeved on one side of the mounting hole close to the center of the mounting plate 1, and the guide column 502 adopts The guide column 502 is made of high-hardness material and is made of tungsten alloy, thereby reducing the loss caused by the friction between the guide column 502 and the mesh wire when the mesh wire slides along the hole in the middle of the guide column 502, thereby increasing the service life of the guide column 502 and avoiding the increase in the diameter of the hole in the guide column 502, which causes the guiding effect of the guide column 502 on the mesh wire to be weakened. A first elastic member 503 is fixedly installed on one side of the guide column 502, and a wire plug 504 is fixedly installed on one side of the first elastic member 503. The wire plug 504 is slidably sleeved with the mounting hole, and a mesh wire is fixedly installed in the middle of the wire plug 504, and the mesh wire is slidably sleeved with the guide column 502.

[0029] like Figures 1 to 4 As shown, the driving mechanism 11 includes a telescopic rod 1101, which is fixedly mounted on the bottom of the supporting foot 2, and the telescopic rod 1101 is fixedly sleeved with the mounting plate 1, and a connecting block 1102 is fixedly mounted on the telescopic end of the telescopic rod 1101, and a connecting rail 1103 is fixedly mounted between the inner sides of two adjacent connecting blocks 1102, and a ladder groove is opened in the middle of the connecting rail 1103, and the mounting block 501 and the push block 6 are slidably sleeved with the ladder groove. By setting the ladder groove, the connecting rail 1103 can move up and down. 1103 can drive the wire clamping mechanism 5 and the push block 6 to move up and down, while the wire clamping mechanism 5 and the push block 6 can slide to both sides along the ladder groove opened on the connecting rail 1103, so that the diameter of the screen formed by the clamping wire on the wire clamping mechanism 5 can be freely changed, and the contact surfaces of the mounting block 501 and the push block 6 with the ladder groove are both smooth surfaces, thereby reducing the thrust of the driving mechanism 11 pushing the push block 6 to move upward when the push block 6 pushes the mounting frame 4 to move to both sides thereof, thereby reducing the load on the telescopic rod 1101.

[0030] Working principle:

[0031] When the present invention is used, the telescopic rod 1101 is started, and the telescopic end of the telescopic rod 1101 drives the connecting block 1102 to move downward, and the connecting block 1102 drives the connecting rail 1103 to move downward, and the connecting rail 1103 drives the wire clamping mechanism 5 and the push block 6 to move downward. At this time, since the shape of the mounting frame 4 is an inverted trapezoid and the shape of the push block 6 is a trapezoid, the push block 6 moves downward and separates from the mounting frame 4, and the second elastic member 9 drives the clamping rod 10 to squeeze the mounting frame 4 to move in the direction of the push block 6 and fit the push block 6, so that the distance between the multiple mounting frames 4 is continuously approached, and the multiple mounting frames 4 drive the multiple wire clamping mechanisms 5 to continuously approach each other, and the multiple wire clamping mechanisms 5 drive the multiple meshes to approach each other until the telescopic end of the telescopic rod 1101 moves After reaching the lowest part, the diameter of the screen formed by the multiple mesh wires reaches the minimum. Then, the material to be screened is placed above the screen. The material squeezes the mesh wires forming the screen and makes them concave downward. The mesh wires pull the fixed wire plug 504 fixedly connected thereto to squeeze the first elastic member 503 to move in the direction of the guide column 502, so that the middle part of the screen formed by the multiple mesh wires concave downward, and the material moves toward the middle part of the middle part of the screen, so as to prevent the material on the surface of the screen from separating from the screen on both sides of the screen. Then, when the screen pushes the material to move upward and separate from the screen, the curved surface formed by the screen pushes the material on its surface to move upward, so that the material moves toward the middle above the screen, so as to prevent the material from falling off the screen surface when it falls downward due to gravity.

[0032] Then, the telescopic rod 1101 is started again, and the telescopic end of the telescopic rod 1101 accelerates to move upward, and the telescopic end of the telescopic rod 1101 drives the connecting rail 1103 to move upward through the connecting block 1102, and the connecting rail 1103 drives the wire clamping mechanism 5 and the push block 6 to move upward, and the mounting frame 4 squeezes the push block 6 to move to both sides thereof, so that the multiple mounting frames 4 drive the multiple wire clamping mechanisms 5 to move away from each other, and the multiple wire clamping mechanisms 5 drive the multiple meshes to move away from each other, so that the diameter of the screen composed of the multiple meshes continues to increase, and the mounting frame 4 squeezes the second elastic member 9 to contract through the clamping rod 10. At this time, the screen accelerates to push the material above it to accelerate upward. When the telescopic end of the rod 1101 accelerates and moves upward until the screen reaches the diameter required for screening the material, the telescopic end of the telescopic rod 1101 begins to decelerate and move upward sharply. At this time, the material on the upper surface of the screen moves upward at the original speed under the action of inertia and separates from the screen. At this time, the diameter of the screen increases slowly, so that the material blocked in the mesh of the screen is separated from the mesh of the screen and moves upward, thereby achieving timely and rapid removal of the material stuck in the mesh of the screen without affecting the normal screening of the material by the screen, overcoming the problem in the prior art that the material stuck in the screen needs to be stopped for cleaning by using a brush, etc., thereby improving the efficiency of material screening;

[0033] When the material blocked in the mesh is separated from the screen, the telescopic end of the telescopic rod 1101 moves downward rapidly to the diameter of the material required for screening, and the telescopic rod 1101 stops moving, so that the screen is fixed to the screening position. At this time, the material moving upward due to inertia moves downward due to gravity and collides with the screen. At this time, the material smaller than the mesh diameter falls under the screen, and the telescopic end of the telescopic rod 1101 then moves downward to reset, thereby realizing efficient screening of the material. In addition, when the present invention is used, according to the requirements of the material screening size, the position when the telescopic end of the telescopic rod 1101 starts to decelerate sharply and move upward and the stop position when the telescopic end of the telescopic rod 1101 moves downward rapidly to the diameter of the material required for screening can be controlled to quickly adjust the diameter of the screen when the screen is screening the material, thereby realizing indirect replacement of the screen, solving the problems that the existing equipment needs to be shut down to replace the screen and needs to provide a large number of screens with different diameters, resulting in low screening efficiency and increased production costs.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
