Description

Technical Field

[0001] The invention relates to the field of sand and gravel preparation machinery, and specifically to an efficiency-enhancing roller sand making machine. Background Art

[0002] Roller sand making machine is mainly used for grinding and processing raw materials such as rock, soil, stone, etc. Roller sand making machine crushes and grinds the raw materials in the middle through two rollers rotating against each other. Roller sand making machine can effectively crush them into particles of required size, providing suitable materials for road construction, building aggregates, etc. Kaolin has good adhesion and plasticity, which can effectively increase the adhesion and plasticity of sand particles, and improve the strength and stability of sand particles. When the roller sand making machine grinds and crushes the raw materials, kaolin is usually used as an abrasive in the roller sand making machine, and then sent to the double-roll sand making machine for crushing. During the crushing process, the addition of kaolin can be fully mixed with other raw materials to form a uniform sand mixture.

[0003] However, kaolin abrasive is fed to the grinding position in a certain amount when added. When the raw materials increase or decrease, the amount of kaolin added will not change. Therefore, it is easy to cause too much or too little kaolin to be mixed with the raw materials during roller sand making. Too much kaolin abrasive will lead to a decrease in processing effect, while too little kaolin abrasive cannot complete the processing task, resulting in the problem that the inflow of kaolin cannot be adjusted according to the amount of raw materials. In addition, kaolin is added to the center position of the roller sand making during feeding, and the grinding position of the roller sand making is linear. The kaolin and the raw materials are not mixed evenly at the grinding position, and the raw materials at some grinding positions are not mixed with kaolin, which affects the mixing of the raw materials and the abrasive. Summary of the invention

[0004] The present invention provides an efficiency-enhanced roller sand making machine, which overcomes the shortcomings described in the background technology.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] An efficiency-enhancing roller sand making machine comprises a feed port, a feed mechanism, a movable roller shaft, a spring device, a fixed roller shaft, a hydraulic device, and a machine platform, wherein the feed port is arranged at the upper end of the feed mechanism, the feed mechanism is arranged at the upper end of the machine platform, the fixed roller shaft and the movable roller shaft are arranged horizontally inside the machine platform, when the raw material enters the feed mechanism from the feed port, it falls between the movable roller shaft and the fixed roller shaft in the machine platform, and the movable roller shaft and the fixed roller shaft rotate in opposite directions to crush the fallen raw material, the spring device is arranged outside the machine platform, and the hydraulic device is supported at the outer end of the spring device, when the movable roller shaft crushes the raw material in the machine platform, the movable roller shaft is elastically supported by the spring device in the machine platform;

[0007] The feeding mechanism is provided with a mixer, a guide plate, a support plate, a storage box, a frame, and a connecting frame. The storage box is arranged inside the frame, and the inner surface of the storage box is arranged to be inclined toward the support plate. The support plate is vertically arranged at the bottom of the frame. The connecting frame is arranged at the upper end of the frame, and the connecting frame is connected to the lower end of the feed port. The guide plate is arranged obliquely on the inner side of the frame. When the raw material slides off the guide plate, the raw material slides to the side of the mixer and falls from the middle of the mixer to the inside of the machine below the frame. The mixer is arranged at the bottom of the frame for support. When raw materials fall on the mixer, the mixer bears the load and moves elastically downward, and slides and cooperates on the inner side of the support plate.

[0008] A preferred technical solution: the mixer is provided with a feed trough, a dispersion plate, a plane plate, a spring rod, and a trapezoidal groove. The plane plate and the dispersion plate are integrally connected and are inclined outward in an open shape. The feed trough is located in the middle of the connection between the plane plate and the dispersion plate. The spring rod is arranged at the lower ends of the dispersion plate and the plane plate and fixed on the surface of the frame. The trapezoidal groove is arranged inside the support plate and is located at the lower left position of the storage box. When the dispersion plate is stationary, the dispersion plate is positioned inside the support plate and blocks the left outlet end of the trapezoidal groove. When the plane plate is pressed by the gravity of the raw material, the dispersion plate is driven to be compressed and moved toward the spring rod, and the outer side of the dispersion plate slides inside the support plate and slides out of the left outlet end of the trapezoidal groove.

[0009] A preferred technical solution: The movable roller and the fixed roller inside the machine are hollow below, and a transmission belt is provided at the hollow position to convey and discharge the raw materials after sand making and grinding.

[0010] A preferred technical solution: the surface of the guide plate is provided with square-arranged grooves, and the raw materials slide evenly from the surface of the guide plate into the mixer.

[0011] A better technical solution: the flat plate guides the raw materials to the feed trough from the left side, the dispersion plate guides the kaolin to the feed trough from the right side, and the raw materials and kaolin are mixed and dropped at the feed trough. The flat plate presses the spring rod downward and slides under the gravity of the raw materials. When the gravity is greater, the downward movement length is greater, and the dispersion plate has less obstruction to the trapezoidal trough, and more kaolin slides out of the storage box from the trapezoidal trough.

[0012] A preferred technical solution: the dispersion plate is provided with a filling strip, a connecting block, a rubber shaft, a sliding plate, and a guide plate. The connecting block is arranged on the outside of the guide plate, and the rubber shaft bearing is arranged on the side of the connecting block. When the guide plate moves downward, the sliding plate on the connecting block slides with the inner side of the support plate, and the rubber shaft slides with the inner side of the support plate to rotate counterclockwise. The filling strip is attached to the upper end of the connecting block. When the rubber shaft rotates counterclockwise, the outer side of the rubber shaft rubs against the filling strip, driving the filling strip to press and slide toward the inner side of the support plate.

[0013] A better technical solution: the sliding plate is provided with equidistantly arranged circular rolling bars, the sliding plate is made of rubber, when the connecting block moves downward, the sliding plate is compressed by the supporting plate, and the circular rolling bars on the sliding plate slide inside the supporting plate.

[0014] A better technical solution: the filling strip is provided with a rubber block, a bending plate, and a fixed shaft, the fixed shaft limiter is set inside the connecting block, the rubber block is fitted to the upper end of the connecting block, the side of the bending plate is fitted by the rubber block, and the bending plate and the outer side of the rubber shaft rotate counterclockwise and rub, so that the bending plate rotates clockwise with the fixed shaft as the center, and pulls the rubber block to move and stretch toward the support plate, so that the bending plate is pressed and slides on the inner side of the support plate.

[0015] A preferred technical solution: The structures of the left side of the plane plate and the right side of the dispersion plate sliding on the side of the support plate are different. Compared with the dispersion plate, the side of the plane plate lacks the rubber shaft and the filling strip.

[0016] A better technical solution: the inclination angle between the plane plate and the dispersion plate is between 40° and 30°, and the inclination angle is just enough to guide the raw materials and kaolin at a uniform speed.

[0017] A better technical solution: A soft rubber strip is provided at the lower end of the bending plate. When the rubber shaft rotates counterclockwise, it deforms and rubs against the rubber strip, and causes the rubber strip to pull the bending plate in the opposite direction to rotate.

[0018] A better technical solution: the guide plate is provided with an inclined plate, a diamond block, and a pendulum block. The diamond blocks are equidistantly arranged on the surface of the inclined plate, the pendulum blocks are equidistantly arranged on the surface of the inclined plate, and the pendulum blocks are located at the upper position of the inclined inclined plate. When kaolin flows out from the outlet end of the trapezoidal trough, it flows evenly to the position of the pendulum block and slides to the diamond block on the surface of the inclined inclined plate to be evenly dispersed.

[0019] A better technical solution: the pendulum block is provided with a triangular block, a plastic strip, and a protruding rod. The protruding rod is arranged inside the inclined plate and limits the movement of the triangular block. The two plastic strips are symmetrically arranged on the left and right sides of the triangular block. When kaolin flows through the triangular block, the triangular block swings 5° left and right with the protruding rod as the center, and the kaolin is elastically guided downward by the plastic strip on the adjacent pendulum block.

[0020] Compared with the prior art, this technical solution has the following advantages:

[0021] In the present invention, the weight of the raw materials sliding from the guide plate to the flat plate drives the dispersion plate to press the spring rod to sink, and makes the dispersion plate and the support plate slide to expose the outlet end of the trapezoidal groove in the support plate. At this time, the kaolin in the storage box freely slides through the trapezoidal groove to the dispersion plate, and the kaolin slides from the right side to the middle of the feed trough, and meets and mixes with the raw materials sliding into the flat plate. The guide plate is used to guide the raw materials to enter the mixer evenly, and the amount of kaolin released from the support plate is controlled through the load-bearing sinking length of the mixer, so that the entry of the raw materials and the feeding of the kaolin are in a certain proportion to prevent the situation of too much or too little kaolin feeding.

[0022] In the present invention, when the inclined plate sinks, the kaolin flowing from the trapezoidal groove flows to the swing block position and is blocked and dispersed by the triangular block. Under the impact of the kaolin flow force, the triangular block swings left and right with the protruding rod as the center, and the triangular block drives the plastic strip to swing as a whole. Therefore, when the kaolin flows, the inclined surface of the triangular block is guided to the side by the left and right swing of the plastic strip, and the kaolin is swung and dispersed in the equidistantly arranged swing blocks, and is evenly dispersed again at the intervals of the diamond blocks below, so that the kaolin is dispersed to the surface of the inclined plate, and is linearly introduced into the feed trough position to be evenly mixed with the raw materials, thereby preventing uneven dispersion of kaolin from affecting the mixing and grinding of the raw materials.

[0035] like Figures 1 to 7 As shown, the present invention proposes an efficiency-enhancing roller sand making machine, including a feed port 1, a feed mechanism 2, a movable roller shaft 3, a spring device 4, a fixed roller shaft 5, a hydraulic press 6, and a machine platform 7. The feed port 1 is arranged at the upper end of the feed mechanism 2, and the feed mechanism 2 is arranged at the upper end of the machine platform 7. The fixed roller shaft 5 and the movable roller shaft 3 are arranged horizontally inside the machine platform 7. When the raw material enters the feed mechanism 2 from the feed port 1, it falls between the movable roller shaft 3 and the fixed roller shaft 5 in the machine platform 7, and the movable roller shaft 3 and the fixed roller shaft 5 rotate in opposite directions to crush the fallen raw material. The spring device 4 is arranged on the outside of the machine platform 7, and the hydraulic press 6 is supported at the outer end of the spring device 4. When the movable roller shaft 3 crushes the raw material in the machine platform 7, the movable roller shaft 3 is elastically supported by the spring device 4 in the machine platform 7;

[0036] The feeding mechanism 2 is provided with a mixer 21, a guide plate 22, a support plate 23, a storage box 24, a frame 25, and a connecting frame 26. The storage box 24 is arranged inside the frame 25, and the inner surface of the storage box 24 is inclined toward the support plate 23. The support plate 23 is vertically arranged at the bottom of the frame 25. The connecting frame 26 is arranged at the upper end of the frame 25, and the connecting frame 26 is connected to the lower end of the feed port 1. The guide plate 22 is inclined at the inner side of the frame 25. When the raw material slides off the guide plate 22, the raw material slides to the side of the mixer 21 and falls from the middle of the mixer 21 to the inside of the machine table 7 below the frame 25. The mixer 21 is arranged at the bottom of the frame 25 for support. When raw materials fall on the mixer 21, the mixer 21 bears the load and moves elastically downward, and slides and cooperates on the inner side of the support plate 23.

[0037] Among them, the mixer 21 is provided with a feed trough 211, a dispersion plate 212, a plane plate 213, a spring rod 214, and a trapezoidal groove 215. The plane plate 213 and the dispersion plate 212 are integrally connected and are inclined outward in an open shape. The feed trough 211 is located in the middle of the connection between the plane plate 213 and the dispersion plate 212. The spring rod 214 is arranged at the lower end of the dispersion plate 212 and the plane plate 213, and is fixed on the surface of the frame 25. The trapezoidal groove 215 is arranged inside the support plate 23 and is located at the lower left position of the storage box 24. When the dispersion plate 212 is stationary, the dispersion plate 212 is located in the support plate 23 and blocks the left outlet end of the trapezoidal groove 215. When the plane plate 213 is pressed by the gravity of the raw material, the dispersion plate 212 is driven to be compressed and moved toward the spring rod 214, and the outer side of the dispersion plate 212 slides in the support plate 23 and slides out of the left outlet end of the trapezoidal groove 215.

[0038] The movable roller shaft 3 and the fixed roller shaft 5 inside the machine platform 7 are hollow, and a transmission belt is provided at the hollow position to convey and discharge the raw materials after sand making and grinding.

[0039] The surface of the guide plate 22 is provided with square-arranged grooves, and the raw materials slide evenly from the surface of the guide plate 22 into the mixer 21 .

[0040] Among them, the flat plate 213 guides the raw material to the feed trough 211 from the left side, and the dispersion plate 212 guides kaolin to the feed trough 211 from the right side, and makes the raw material and kaolin mix and fall at the feed trough 211. The flat plate 213 presses the spring rod 214 downward and slides under the gravity of the raw material. When the gravity is greater, the downward movement length is greater, and the dispersion plate 212 has less obstruction to the trapezoidal groove 215, and more kaolin slides out of the storage box 24 from the trapezoidal groove 215.

[0041] In the present invention, the sand making raw material enters the frame 25 from the feed port 1, and the raw material is guided by the guide plate 22 to the position of the flat plate 213 on the left side of the mixer 21, and slides to the middle feed trough 211 at the position of the flat plate 213. At the same time, the weight of the raw material on the flat plate 213 drives the dispersion plate 212 to press the spring rod 214 to sink, and makes the dispersion plate 212 and the support plate 23 slide to expose the outlet end of the trapezoidal groove 215 in the support plate 23. At this time, the kaolin in the storage box 24 slides freely through the trapezoidal groove 215 to the dispersion plate 212, and the kaolin slides from the right side to the middle of the feed trough 211 and The raw materials sliding into the plane plate 213 meet and mix, and fall to the grinding position between the movable roller shaft 3 and the fixed roller shaft 5 in the middle position of the feed trough 211, and the movable roller shaft 3 is elastically moved by the spring device 4 under the elastic adjustment of the hydraulic press 6 to the spring device 4, and the grinding between the movable roller shaft 3 and the fixed roller shaft 5 is uniformly sanded under a certain grinding force, wherein the guide plate 22 is used to guide the raw materials to evenly enter the mixer 21, and the amount of kaolin released from the support plate 23 is controlled through the load-bearing sinking length of the mixer 21, so that the entry of the raw materials and the feeding of kaolin are in a certain proportion to prevent the situation of excessive or insufficient feeding of kaolin.

[0042] Among them, the dispersion plate 212 is provided with a filling strip 2121, a connecting block 2122, a rubber shaft 2123, a sliding plate 2124, and a guide plate 2125. The connecting block 2122 is arranged on the outside of the guide plate 2125, and the bearing of the rubber shaft 2123 is arranged on the side of the connecting block 2122. When the guide plate 2125 moves downward, the sliding plate 2124 on the connecting block 2122 slides with the inner side of the support plate 23, and the rubber shaft 2123 slides with the inner side of the support plate 23 to rotate counterclockwise, and the filling strip 2121 is attached to the upper end of the connecting block 2122. When the rubber shaft 2123 rotates counterclockwise, the outer side of the rubber shaft 2123 rubs against the filling strip 2121, driving the filling strip 2121 to press and slide toward the inner side of the support plate 23.

[0043] In addition, the sliding plate 2124 is provided with equidistantly arranged circular rolling bars, and the sliding plate 2124 is made of rubber. When the connecting block 2122 moves downward, the sliding plate 2124 is compressed by the supporting plate 23, and the circular rolling bars on the sliding plate 2124 slide inside the supporting plate 23.

[0044] Among them, the filling strip 2121 is provided with a rubber block 1211, a bending plate 1212, and a fixed shaft 1213. The fixed shaft 1213 is limitedly set inside the connecting block 2122. The rubber block 1211 is fitted on the upper end of the connecting block 2122. The side of the bending plate 1212 is fitted by the rubber block 1211, and the bending plate 1212 and the outer side of the rubber shaft 2123 rotate counterclockwise and rub, so that the bending plate 1212 rotates clockwise with the fixed shaft 1213 as the center, and pulls the rubber block 1211 to stretch toward the support plate 23, so that the bending plate 1212 presses and slides on the inner side of the support plate 23.

[0045] In addition, the structures of the left side of the plane plate 213 and the right side of the dispersion plate 212 sliding on the side of the support plate 23 are different. Compared with the dispersion plate 212, the side of the plane plate 213 lacks the rubber shaft 2123 and the filling strip 2121.

[0046] Furthermore, the plane plate 213 and the dispersion plate 212 have an inclination angle between 40° and 30°, which is just the right angle to guide the raw materials and kaolin at a uniform speed.

[0047] In addition, a soft rubber strip is provided at the lower end of the bending plate 1212. When the rubber shaft 2123 rotates counterclockwise, it deforms and rubs against the rubber strip, and causes the rubber strip to pull the bending plate 1212 in the opposite direction to rotate.

[0048] In the present invention, when the dispersion plate 212 sinks and slides with the side of the support plate 23, the sliding plate 2124 is compressed and guided to move by the circular rolling bar, and the outer side of the rubber shaft 2123 is blocked by the friction of the inner side of the support plate 23. After the connecting block 2122 moves down, the rubber shaft 2123 rotates counterclockwise and rubs the filling strip 2121 counterclockwise against the soft rubber strip of the bending plate 1212, so that the bending plate 1212 rotates clockwise around the fixed shaft 1213 as the center, and pulls the rubber block 1211 to approach the side of the support plate 23. At this time, the bending plate 1212 is pressed against the The rubber block 1211 is driven to approach the side of the support plate 23 and prevents the generation of a gap under the sliding of the bending plate 1212 without affecting the downward movement of the connecting block 2122, thereby preventing the kaolin sliding down the trapezoidal groove 215 from falling from the gap between the dispersion plate 212 and the support plate 23. The sliding plate 2124 on the side of the connecting block 2122 gradually exposes the position of the trapezoidal groove 215 when moving, and exposes a larger position of the trapezoidal groove 215 under the gravity sinking of the guide plate 2125.

[0049] Among them, the guide plate 2125 is provided with an inclined plate 31, a diamond block 32, and a pendulum block 33. The diamond blocks 32 are equidistantly arranged on the surface of the inclined plate 31, and the pendulum blocks 33 are equidistantly arranged on the surface of the inclined plate 31. The pendulum blocks 33 are located at the upper position of the inclined inclined plate 31. When kaolin flows out from the outlet end of the trapezoidal groove 215, it flows evenly to the position of the pendulum block 33, and slides to the diamond block 32 on the surface of the inclined inclined plate 31 and is evenly dispersed.

[0050] In addition, the swing block 33 is provided with a triangular block 331, a plastic strip 332, and a protruding rod 333. The protruding rod 333 is arranged inside the inclined plate 31 and limits the movement of the triangular block 331. The two plastic strips 332 are symmetrically arranged on the left and right sides of the triangular block 331. When kaolin flows through the triangular block 331, the triangular block 331 swings 5° left and right with the protruding rod 333 as the center, and the kaolin is elastically guided downward by the plastic strip 332 on the adjacent swing block 33.

[0051] In the present invention, when the inclined plate 31 sinks, the kaolin flowing from the trapezoidal groove 215 flows to the swing block 33, and is blocked and dispersed by the triangular block 331. Under the impact of the kaolin flow force, the triangular block 331 swings left and right with the protruding rod 333 as the center, and the triangular block 331 drives the plastic strip 332 to swing as a whole. Therefore, when the kaolin flows, the inclined surface of the triangular block 331 is guided to the side by the left and right swing of the plastic strip 332, and the kaolin is swung and dispersed in the equidistantly arranged swing blocks 33, and is evenly dispersed again at the intervals of the diamond blocks 32 below, so that the kaolin is dispersed to the surface of the inclined plate 31, and is linearly introduced into the position of the feed trough 211 to be evenly mixed with the raw materials, thereby preventing the uneven dispersion of kaolin from affecting the mixing and grinding of the raw materials.

[0052] It is necessary to explain that kaolin is a non-metallic mineral, a clay and clay rock mainly composed of kaolinite clay minerals. The particle size of kaolin as a grinding medium should be 0.8-3mm. When the raw materials and kaolin are mixed and ground in the present invention, the ratio of the raw materials (rock, stone) to kaolin is usually 500 grams of kaolin per cubic meter of raw materials. In the present invention, each cubic meter of raw material is uniformly introduced at a certain speed and time, and 500 grams of kaolin is also uniformly introduced at this speed and time. In the present invention, the ratio of kaolin introduction and mixing is automatically adjusted according to the weight of the raw materials. When too much raw material is introduced, the amount of kaolin introduced is increased according to the ratio of 500 grams of kaolin mixed into each cubic meter of raw material. In addition, in the case of changes in the humidity and dryness of the raw materials, the proportion of kaolin in the raw material grinding and the specific application need to be adjusted according to the actual situation to achieve the best grinding effect and product quality.

[0053] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
