Description

Technical Field

[0001] This invention relates to the technical field of concrete screening, and more particularly to a quantitative screening concrete batching machine and its batching control method. Background Technology

[0002] Concrete is a building material made of binder, coarse and fine aggregates and water in a certain proportion. It is widely used in construction projects. In the production process of concrete, concrete batching machines are needed to proportion and mix various raw materials. Before batching, concrete raw materials usually need to be screened to remove impurities and particles that do not meet the size requirements.

[0003] In practical use, larger particles in the raw materials gradually accumulate on the screen, causing blockage and obstruction of the screen holes, resulting in a significant decrease in screening efficiency. Furthermore, it is difficult for users to handle these large particles in a timely and effective manner, affecting the continuity and accuracy of subsequent batching. Only coarse screening can be performed, and effective grading of coarse and fine aggregates cannot be achieved. The screened materials often require additional conveying and mixing devices for mixing, resulting in a fragmented structure of the entire batching system. This not only occupies a large amount of space but also increases equipment costs and the complexity of material flow. Summary of the Invention

[0017] The beneficial effects of this invention are as follows: the concrete raw materials are screened in two stages by a coarse screening mechanism and a fine screening mechanism, and a stirring mechanism and a mixing mechanism are set at the bottom of the feeding hopper, thereby reducing the material flow links. The bending rod is driven by a pneumatic rod, which drives the cleaning plate to reciprocate on the top of the screen plate, automatically sweeping the large particles remaining on the screen plate to the collection plate for discharge. The periodic movement of the eccentric plate drives the sliding plate, which causes the vibrating rod to drive the screen plate to generate high-frequency vibration, thereby enhancing the screening efficiency of the screen plate.

[0018] In view of the problems existing in the above-mentioned quantitative screening concrete batching control methods, the present invention is proposed.

[0019] Therefore, the purpose of this invention is to provide a quantitative screening method for controlling concrete batching, the purpose of which is to: transport and screen raw materials, prevent screening blockage, collect waste materials, and mix and stir the raw materials.

[0020] To solve the above-mentioned technical problems, the present invention provides the following technical solution: It includes a two-stage screening of concrete raw materials through a coarse screening mechanism and a fine screening mechanism; a stirring mechanism and a mixing mechanism are set at the bottom of the feeding hopper to reduce material flow links; a pneumatic rod drives a bending rod to move a cleaning plate back and forth on the top of the screen plate, automatically sweeping large particles remaining on the screen plate to the collection plate for discharge; the periodic movement of the eccentric plate drives a sliding plate to cause a vibrating rod to drive the screen plate to generate high-frequency vibration, thereby enhancing the screening efficiency of the screen plate.

[0021] As a preferred embodiment of the quantitative screening concrete batching control method of the present invention, the method includes: setting up a coarse screening mechanism and a fine screening mechanism to realize two-stage screening of concrete raw materials, and performing preliminary screening of raw materials to separate larger particles. Subsequently, the material enters the screen barrel and is finely screened through the fine screen holes, which effectively improves the screening and grading effect; the pneumatic rod drives the bending rod to drive the cleaning plate to reciprocate on the top of the screen plate, sweeping away the large particles remaining on the screen plate and preventing blockage; the periodic movement of the eccentric plate drives the sliding plate to generate high-frequency vibration of the screen plate, which enhances the screening efficiency of the screen plate and prevents the material from sticking to the screen mesh.

[0022] Another beneficial effect of this invention is that by setting up a coarse screening mechanism and a fine screening mechanism, two-stage screening of concrete raw materials is achieved. The screen plate in the feed bucket first performs preliminary screening of the raw materials, separating larger particles. Then, the material enters the screen bucket and is finely screened through the fine screen holes, which effectively improves the screening quality and grading effect of aggregates and ensures the accuracy of subsequent concrete batching. The pneumatic rod drives the bending rod to move the cleaning plate back and forth on the top of the screen plate, automatically sweeping the large particles remaining on the screen plate to the collection plate for discharge, effectively preventing screen hole blockage. The addition of a top-out block, activated by a small cylinder, moves the top-out block upward to clean the holes in the screen. Particles continue to fall through the holes, further preventing screen plate blockage. The servo motor drives the eccentric plate to rotate, and the periodic movement of the eccentric plate pushes the sliding plate and spring assembly, causing the vibrating rod to drive the screen plate to generate high-frequency vibration, which enhances the screening efficiency of the screen plate, helps fine particles pass through the screen holes, and prevents materials from sticking to the screen.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the present invention is described in detail with reference to the schematic diagrams.

[0039] Example 1

[0040] Reference Figures 1-11This is the first embodiment of the present invention, which provides a quantitative screening concrete batching control method. Through the quantitative screening concrete batching machine and its batching control method, the effects of effective screening, raw material conveying, mixing and stirring, stone blockage prevention and waste collection are achieved.

[0041] By setting up a coarse screening mechanism 200 and a fine screening mechanism 300, two-stage screening of concrete raw materials is achieved. The coarse screening mechanism 200 performs preliminary screening of the raw materials, separating out larger particles. The material after coarse screening then enters the screen barrel 302 of the fine screening mechanism 300, where it undergoes fine screening through the fine screen holes 304, thereby significantly improving the screening and grading effect. At the same time, the pneumatic rod 203a drives the bending rod 203b, which in turn drives the cleaning plate 203c to reciprocate on the top of the screen plate 202, automatically sweeping the large particles remaining on the screen plate 202 to the collection point. The material is discharged at plate 203d, effectively preventing screen hole clogging. In addition, the periodic movement of eccentric plate 204c drives sliding plate 204d, causing vibrating rod 204j to drive screen plate 202 to generate high-frequency vibration. With the help of ejector block 205b, which is activated by small cylinder 205c, ejector block 205b moves upward to clean the holes in the screen. The particles continue to fall through the holes, further preventing screen plate 202 from clogging. This not only enhances the screening efficiency of screen plate 202, but also effectively prevents material from sticking to the screen, ensuring a continuous and stable screening process.

The right side of the vibration rod 204j passes through to the left side of the inner wall of the feeding bucket 201 and is fixedly connected to the left side of the screen plate 202.

[0049] A shaft 101a is movably connected to the back end of the inner wall of the metal frame plate 101 and the top of the output rod 204b via a rotating shaft. The shaft 101a and the output rod 204b are connected by a transmission belt, and the shaft 101a and the conveyor belt 104 are connected by a transmission belt.

[0050] A collection chamber 404a is fixedly connected to the top of the first limiting sleeve 404 and the bottom of the corresponding rockfall outlet 305. The collection chamber 404a is used in conjunction with the fixed bucket 301 and the sieve bucket 302.

[0051] A plate opening 101b is provided on the back end of the metal frame plate 101, corresponding to the position of the servo motor 204a and the output rod 204b. A motor plate 101c is fixedly connected to the back end of the inner wall of the metal frame plate 101, corresponding to the position of the plate opening 101b. The back end of the rectangular block 204f is fixedly connected to the front end of the motor plate 101c.

[0052] Specifically, the conveying mechanism 100 achieves stable material transport. The guard plates 102 and inclined plates 103 on both sides of the metal frame plate 101 form a guiding structure to ensure that the material does not spill when transported on the conveyor belt 104, providing a continuous and stable material flow for the subsequent screening process. Through the cooperation of the coarse screening mechanism 200 and the fine screening mechanism 300, efficient two-stage screening is achieved. The material first undergoes preliminary screening through the screen plate 202 in the feed bucket 201 to separate larger particles. Then, it enters the screen bucket 302 and undergoes secondary fine screening through the fine screen holes 304, and is discharged through the stone drop outlet 305, which significantly improves the screening accuracy and grading effect. The cleaning component 203 achieves automatic cleaning of the screen plate.

[0053] Specifically, the pneumatic rod 203a drives the bending rod 203b, which in turn drives the cleaning plate 203c to reciprocate at the top of the screen plate 202. This automatically pushes the remaining large particles to the collection plate 203d for discharge, preventing the screen plate 202 from clogging and ensuring the continuous smoothness of the coarse screening process. The vibration component 204 enhances the screening efficiency of the screen plate. The servo motor 204a drives the output rod 204b to rotate the eccentric plate 204c, which in turn pushes the sliding plate 204d. With the cooperation of the spring assembly 204g and the rebound plate 204h, the vibration connecting plate 204i drives the vibration rod 204j to impact the screen plate 202 at high frequency, accelerating the material screening speed. The addition of the ejector block 205b, which is activated by the small cylinder 205c, moves the ejector block 205b upward to clean the holes in the screen. The particles continue to fall through the holes, further preventing the screen plate 202 from clogging and preventing the material from sticking to the screen.

[0054] Specifically, the power of the output rod 204b is synchronously transmitted to the conveyor belt 104 using the shaft 101a, realizing that the power of the vibration component and the conveying link are from the same source, reducing additional power components, and making the whole machine move more coordinated. The collection bin 404a, which is fixedly connected to the top of the first limit sleeve 404, is located at the bottom of the rock drop outlet 305, ensuring that larger stones or tailings discharged from the screen barrel 302 can be accurately received and prevented from scattering. The internal structural layout is optimized by setting the motor plate 101c and the plate opening 101b. The servo motor 204a is fixed to the motor plate 101c through the plate opening 101b, and the rectangular block 204f is also connected to the motor plate 101c, making the installation structure of the vibration component 204 more stable and easier to maintain, thus improving the stability of the equipment operation.

[0055] Furthermore, the concrete raw material to be screened is placed on the conveyor belt 104 of the conveying mechanism 100. The conveyor belt 104 operates under power drive, transporting the raw material to the right. The guard plate 102 prevents the raw material from spilling from both sides during the transport process, and the inclined plate 103 acts as a guide to ensure that the raw material smoothly enters the next station. The raw material first falls into the feed hopper 201 of the coarse screening mechanism 200 and lands on top of the screen plate 202. The servo motor 204a drives the output rod 204b to rotate, and the output rod 204b drives the eccentric plate 204c to rotate. During rotation, the eccentric plate 204c periodically contacts and pushes the sliding plate 204d. The sliding plate 204d slides to the right along the sliding rod 204e, while compressing the spring assembly 204g. When the eccentric plate 204c rotates away, the spring assembly 204g releases its elastic force, which pushes the vibrating connecting plate 204i and the vibrating rod 204j to rebound quickly to the left through the rebound plate 204h. The vibrating rod 204j is fixedly connected to the screen plate 202, thereby driving the screen plate 202 to generate continuous high-frequency left and right reciprocating vibration, which efficiently screens the raw materials on the screen plate 202.

[0056] Furthermore, during the vibration of the screen plate 202, small fine particles pass through the screen plate 202 and fall into the bottom of the feed hopper 201, while large coarse particles are trapped at the top of the screen plate 202. The cleaning component 203 is activated, and the air rod 203a drives the bending rod 203b to move to the right, which drives the cleaning plate 203c to clean from left to right on the top of the screen plate 202, pushing the accumulated coarse particles to the right and collecting them through the collection plate 203d to prevent the screen plate 202 from clogging.

[0057] Furthermore, after the fine material passing through the sieve plate 202 falls into the bottom of the feeding bucket 201, it enters the sieve bucket 302 of the fine sieve mechanism 300 through the opening on the right side of the feeding bucket 201. The sieve bucket 302 continues to rotate under the drive of the third rotating rod 412. Fine material with a particle size smaller than the fine sieve hole 304 falls through the fine sieve hole 304 into the bottom of the fixed bucket 301 during the rotation of the sieve bucket 302, and then falls into the feeding bucket 401 of the stirring mechanism 400. Larger particles or stones roll with the bucket wall in the sieve bucket 302 and are finally discharged from the stone drop outlet 305 on the right side and fall into the collection bin 404a below for collection.

[0059] Reference Figures 8-11 In the third embodiment of the present invention, a stirring mechanism 400 is provided, which achieves the effect of stirring and mixing.

[0060] The mixing mechanism 400 includes a discharge bucket 401, which is located at the bottom of a fixed bucket 301. The front and back ends of the discharge bucket 401 are fixedly connected to the front and back ends of a metal frame plate 101. A mixing bucket 402 is movably connected to the right side of the discharge bucket 401 via a rotating shaft. The inner cavity of the mixing bucket 402 is provided with an internal thread 403. A first limiting sleeve 404 and a second limiting sleeve 405 are movably sleeved on the surface of the mixing bucket 402 via a rotating shaft. The first limiting sleeve 404 is located to the left of the second limiting sleeve 405. A support frame 406 is fixedly connected to the bottom of the first limiting sleeve 404 and the second limiting sleeve 405. The bottom of the support frame 406 is fixedly connected to the bottom of the inner wall of the metal frame plate 101. A long rod 407 is provided in the inner cavity of the mixing bucket 402. The left side of the long rod 407 extends through to the left side of the discharge bucket 401. The left side of the long rod 407 is fixed. A first rotating rod 408 is connected, and the left side of the first rotating rod 408 is movably connected to the left side of the inner wall of the metal frame plate 101 via a rotating shaft. The right side of the long rod 407 passes through the right side of the mixing tank 402 and is fixedly connected to the first gear 409. The right side of the first gear 409 is fixedly connected to the second rotating rod 410, and the right side of the second rotating rod 410 is movably connected to the right side of the inner wall of the metal frame plate 101 via a rotating shaft. A rod sleeve 411 is fixedly fitted on the surface of the long rod 407 and corresponding to the right side of the mixing tank 402. The left side of the rod sleeve 411 is fixedly connected to the right side of the mixing tank 402. A third rotating rod 412 is fixedly connected to the inner cavity of the rotating sleeve 303. The left side of the third rotating rod 412 passes through the left side of the feeding tank 201 and is movably connected to the left side of the inner wall of the metal frame plate 101 via a rotating shaft. The first rotating rod 408 and the third rotating rod 412 are connected by a transmission belt.

[0061] The mixing mechanism 500 includes a mixing tank 501, which is located on the right side of the stirring tank 402. The bottom of the mixing tank 501 is fixedly connected to the bottom of the inner wall of the metal frame plate 101. A tank connecting plate 502 is fixedly connected to the left side of the mixing tank 501. The left side of the tank connecting plate 502 is fixedly connected to the right side of the support frame 406. A mixing blade 503 is provided at the bottom of the inner wall of the mixing tank 501 via a motor. A transmission rod 504 is fixedly connected to the top of the mixing blade 503. A second gear 505 is fixedly connected to the top of the transmission rod 504. The right side of the second gear 505 is meshed with the bottom of the first gear 409.

[0062] Specifically, during rotation, the long rod 407 conveys the material in the discharge bucket 401 to the right, and drives the mixing bucket 402 to rotate slowly through the rod sleeve 411. The internal thread 403 in the inner cavity of the mixing bucket 402 causes the material to be tumbled while moving forward, achieving uniform preliminary mixing and reducing material flow links. The mixing bucket 402 is movably sleeved in the first limiting sleeve 404 and the second limiting sleeve 405 through the rotating shaft, and the bottom is fixedly supported by the support frame 406, ensuring the coaxiality and operational stability of the mixing bucket 402 during rotation and avoiding swaying caused by the long rod 407.

[0063] Specifically, the mixing blade 503 is independently driven by a motor at the bottom of the inner wall of the mixing drum 501. Combined with the transmission from the first gear 409, this ensures that the mixing blade 503 has sufficient speed and torque. The transmission rod 504 connects the mixing blade 503 and the second gear 505, so that the material that has been initially stirred is fully and evenly mixed in the mixing drum 501, thereby improving the quality of the ingredients.

[0064] Furthermore, the mixing drum 402 continues to rotate under the drive of the long rod 407 and the rod sleeve 411. The internal thread 403 set on the inner wall of the mixing drum 402 plays the role of spiral conveying when the drum rotates, pushing the material to the right. At the same time, the thread structure performs preliminary tumbling and stirring of the material, so that materials of different particle sizes are initially mixed. The material after preliminary stirring is discharged from the right outlet of the mixing drum 402 and enters the mixing drum 501 of the mixing mechanism 500. The motor at the bottom of the mixing drum 501 drives the mixing blade 503 to rotate at high speed, performing final fine mixing of the material to ensure the uniformity of the concrete batch.

[0065] The remaining structure is the same as that in Example 2.

[0066] Example 4

[0067] Reference Figures 1-11 This is the fourth embodiment of the present invention, which differs from the third embodiment in that: this embodiment provides a quantitative screening concrete batching machine.

[0068] Concrete raw materials are fed onto the conveyor belt 104 of the conveying mechanism 100 via external feeding equipment. Guard plates 102 and inclined plates 103 prevent material from spilling from both sides during transport. A servo motor 204a, fixed to a motor plate 101c, is started. Its output end passes through the plate opening 101b, driving the output rod 204b to rotate. The output rod 204b drives the shaft 101a to rotate synchronously via a transmission belt. The shaft 101a then drives the conveyor belt 104 to rotate via another set of transmission belts. This allows one motor to simultaneously drive the screen plate vibration and material conveying.

[0069] The output rod 204b rotates, causing the two eccentric plates 204c, which are fixedly sleeved on its surface, to perform circular motion. The eccentric plates 204c periodically strike the sliding plate 204d, pushing it to slide to the right on the sliding rod 204e. When the eccentric plates 204c rotate away, the spring assembly 204g releases its elastic force, pushing the return plate 204h to reset, thereby driving the vibrating connecting plate 204i and the vibrating rod 204j to perform high-frequency reciprocating motion. The vibrating rod 204j directly strikes the screen plate 202, causing the screen plate 202 to generate high-frequency vibration. Fine particles in the material fall through the holes 205d on the surface of the screen plate 202 and the sliding plate 205a to the bottom of the feed hopper 201, while large particles are trapped on the screen plate 202. The cleaning component 203 is independent of the mechanical transmission. The cleaning plate 202 is driven by a pneumatic rod 203a, which pushes a bending rod 203b to move a sweeping plate 203c back and forth from left to right on top of the sieve plate 202. The sweeping plate 203c pushes large particles that cannot pass through the sieve plate 202 to the right side of the sieve plate 202, and finally discharges them through the collection plate 203d, preventing the sieve holes from clogging. After the pneumatic rod 203a completes one operation, the small cylinder 205c is activated. At this time, the ejector block 205b moves upward with the movement of the sliding plate 205a. The tip of the ejector block 205b pushes out the particles stuck in the holes of the sieve plate 202. The particles fall out of the drain hole 205d, enhancing the cleaning effect of the sieve plate 202 and preventing a small number of particles from getting stuck in the holes of the sieve plate 202.

[0070] The material that has passed through the coarse screen enters the fine screen mechanism 300 from the bottom of the feeding hopper 201. The power of the servo motor 204a is transmitted to the first rotating rod 408 through the output rod 204b. The first rotating rod 408 is connected to the third rotating rod 412 through the transmission belt. The third rotating rod 412 rotates, which drives the screen hopper 302 to rotate at a low speed inside the fixed hopper 301 through the rotating sleeve 303. The material enters the rotating screen hopper 302. Fine materials with a diameter smaller than the fine screen hole 304 pass through the screen hole and fall into the stirring mechanism 400 below. Large materials such as stones and impurities that cannot pass through the fine screen hole 304 move to the right under the action of the rotation of the screen hopper 302. When the large materials move to the point where the stone drop outlet 305 on the right side of the screen hopper 302 is aligned with the stone drop outlet 305 of the fixed hopper 301, the material is discharged. The discharged waste falls into the collection bin 404a fixedly connected below for collection. The fine materials screened by the fine screen mechanism 300 fall into the feeding hopper 401.

[0071] The motor at the bottom of the inner wall of the mixing tank 501 starts, driving the mixing blade 503 to rotate. The mixing blade 503 drives the second gear 505 at the top to rotate through the transmission rod 504. The second gear 505 meshes with the first gear 409. Since the first gear 409 is fixed to the end of the long rod 407, the rotation of the first rotating rod 408 drives the long rod 407 to rotate. The long rod 407 rotates inside the mixing tank 402, pushing the material to the right. The long rod 407 drives the mixing tank 402 to rotate under the support of the first limiting sleeve 404 and the second limiting sleeve 405 through the rod sleeve 411. The internal thread 403 on the inner wall of the mixing tank 402 cooperates with the rotating long rod 407 to perform preliminary mixing of the material. The material enters the mixing tank 501 from the right side of the mixing tank 402, ensuring that the rotation of the mixing tank 402 and the mixing action of the mixing tank 501 are coordinated.

[0072] By opening a plate opening 101b at the back end of the metal frame plate 101 and fixing the motor plate 101c, a stable mounting base is provided for the servo motor 204a and the rectangular block 204f, which also facilitates the maintenance and repair of the equipment and enhances the stability and reliability of the overall structure.

[0073] In summary, the servo motor 204a and the motor at the bottom of the mixing blade 503 provide power. The servo motor 204a directly drives the output rod 204b and the eccentric plate 204c to realize the vibration function of the vibration component 204. The output rod 204b transmits power to the upper shaft 101a through the transmission belt. The shaft 101a then drives the conveyor belt 104 to rotate through the transmission belt, realizing the matching of the feeding speed and the screening speed. The motor drives the mixing blade 503 inside the mixing tank 501 to rotate, transmitting power to the transmission rod 504. At the same time, the first gear 409 meshes with the second gear 505, driving the first rotating rod 408 to rotate synchronously with the rod sleeve 411 and the first gear 409 through the long rod 407. The rod sleeve 411 rotates with the mixing tank 402. The third rotating rod 412 is connected to the first rotating rod 408 through the transmission belt and rotates with the first rotating rod 408, realizing the synchronous operation of the mixing function and the screening function.
