Description

Technical Field

[0001] This invention relates to the field of concrete building material preparation technology, specifically to a method and apparatus for preparing a water-reducing agent for concrete with reduced adhesive content. Background Technology

[0002] Concrete is an artificial stone material made by mixing cementitious materials, granular aggregates, water, and, if necessary, admixtures and additives in a certain proportion, and then uniformly mixing, compacting, and curing it. Concrete water-reducing agents are currently the most commonly used concrete admixtures.

[0003] However, the preparation equipment currently used for the processing of water-reducing concrete adhesives still has certain shortcomings: most of the existing preparation equipment suffers from low mixing efficiency and poor mixing uniformity, and the existing preparation equipment is prone to the phenomenon of raw materials adhering to the inner wall of the mixing tank during use.

[0004] To address the aforementioned problems, the inventors have proposed a method and apparatus for preparing a water-reducing agent for concrete that reduces adhesive content. Summary of the Invention

[0005] To address the shortcomings of existing preparation devices, such as low mixing efficiency, poor mixing uniformity, and the tendency for raw materials to adhere to the inner wall of the mixing tank, the present invention aims to provide a method and apparatus for preparing a binder-reducing concrete water-reducing agent.

A symmetrically distributed L-shaped bracket is fixedly connected to the end of the supporting base plate away from the shaking mechanism. A transverse carrier plate is fixedly connected to the end of the L-shaped bracket away from the supporting base plate.

A second rotating rod is rotatably inserted on a fixed support, and a connecting bevel gear is fixedly sleeved at the end of the second rotating rod. The connecting bevel gear meshes with a first side gear. A rotating sleeve is rotatably sleeved on the first rotating rod, and the rotating sleeve is rotatably inserted at the top of the mixing tank.

An array of second stirring blades is fixedly installed on the inner wall of the cleaning scraper, and the second stirring blades are staggered with the first stirring blades.

[0008] Preferably, the swaying mechanism includes an L-shaped side rod, a U-shaped support, and a mounting bracket. The L-shaped side rod is fixedly installed on the opposite side of the guide slider, and a movable slider is fixedly connected to the end of the L-shaped side rod. A first spring is fixedly installed on the side of the movable slider away from the L-shaped support, and a connecting side block is fixedly connected to the end of the first spring away from the movable slider.

A guide push plate is integrally formed on the outer wall of the fixed collar. An installation collar is fixedly fitted on the third rotating rod, and a second spring is fixedly connected to the outer wall of the installation collar. The second spring is movably fitted on the third rotating rod, and an installation rotating ring is fixedly connected at the end of the second spring away from the installation collar. The installation rotating ring is movably fitted on the third rotating rod and is rotatably connected to the U-shaped support. A rotating sleeve is rotatably inserted into the U-shaped support, and the rotating sleeve... A winding wheel is fixedly connected to the end of the cylinder away from the second servo motor.

The U-shaped connecting rod is fixedly connected to the guide slider. A wedge-shaped protrusion is fixedly installed on one side of the top of the mounting bracket, and the guide push plate can move in contact with the wedge-shaped protrusion.

[0009] Preferably, the striking mechanism includes a connecting gear, which is rotatably mounted on a transverse carrier plate and is symmetrically distributed. A double-sided rack and a single-sided rack are meshed on the outer side of the connecting gear, and both racks are slidably mounted on the transverse carrier plate. The double-sided rack is fixedly connected to the mixing tank. A symmetrically arranged fourth rotating rod is rotatably inserted into the transverse carrier plate, and the connecting gear is rotatably sleeved on the fourth rotating rod. One end of the double-sided rack is fixedly connected to a side connecting rod, which is fixedly connected to the mixing tank. An L-shaped sliding plate is fixedly connected to the end of the single-sided rack away from the mixing tank. A transverse sliding rod is slidably inserted into the L-shaped sliding plate, and a rubber ball is fixedly connected to one end of the transverse sliding rod, allowing the rubber ball to contact the mixing tank.

The third spring is movably sleeved on the transverse sliding rod, and the end of the third spring away from the limiting ring is fixedly connected to the L-shaped sliding plate.

[0010] A method for preparing a binder-reducing concrete water-reducing agent preparation device includes the following steps: Step 1: Remove the sealing barrel cover, then introduce the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent into the mixing barrel through the feeding pipe, then reset the sealing barrel cover and turn on the first servo motor and the second servo motor; Step two: The first servo motor drives the first rotating rod to rotate, which in turn drives the first side gear and the first mixing blade to rotate. This, in turn, works with the second rotating rod to drive the connecting bevel gear to rotate, which in turn drives the second side gear to rotate in the opposite direction. Simultaneously, the second side gear rotates in the opposite direction, which in turn drives the rotating sleeve to rotate in the opposite direction, thereby driving the cleaning scraper and the second mixing blade to rotate in the opposite direction. This allows the first and second mixing blades to rotate in opposite directions on the same axis, thus enabling the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent to be fully and quickly mixed. Step three, simultaneously, the second servo motor drives the rotating column to rotate, which in turn drives the third rotating rod to rotate. This, in turn, drives the guide push plate to rotate via the fixed collar. When the guide push plate contacts the limiting protrusion, it drives the winding wheel to rotate via the limiting protrusion, thus gradually winding up the traction wire rope. The traction wire rope then drives the U-shaped connecting rod to move away from the L-shaped bracket. Furthermore, the guide slider drives the mixing tank and the L-shaped side rod to move away from the L-shaped bracket. Simultaneously, the L-shaped side rod moves, driving the moving slider to move, thus compressing the corresponding first spring. When the guide push plate contacts the wedge-shaped protrusion, it moves away from the winding wheel under the action of the wedge-shaped protrusion, thereby driving the third rotating rod to move via the fixed collar. The movement of the guide plate, which in turn moves the mounting collar and squeezes the second spring, causes the guide plate to separate from the limiting protrusion when it contacts the side of the wedge-shaped protrusion. At this time, the first spring pushes the moving slider to reset, thereby driving the mixing drum to reset through the cooperation of the L-shaped side rod and the guide slider. Then, the winding wheel can be reset and rotated through the traction wire rope. When the guide plate separates from the wedge-shaped protrusion, the second spring drives the third rotating rod to reset through the mounting collar, thereby driving the fixed collar and the guide plate to reset. The above steps are repeated, thereby driving the mixing drum to perform intermittent reciprocating motion, thereby shaking the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent in the mixing drum, thereby further improving the mixing efficiency and uniformity of the raw materials. Step four: When the mixing tank moves away from the L-shaped support, the side connecting rod drives the racks on both sides to move, which in turn drives the rack on one side to move away from the mixing tank via the connecting gear. This, in turn, drives the corresponding transverse sliding rod via the L-shaped sliding plate. During this process, the third spring drives the transverse sliding rod to move closer to the mixing tank via the limiting ring, which in turn drives the rubber ball to move and impact the mixing tank. Later, when the limiting disc contacts the L-shaped sliding plate, the rubber ball will stop moving and will separate from the mixing tank. When the mixing tank returns to its original position, it will contact and impact the rubber ball. The mixing tank will then drive the transverse sliding rod via the rubber ball to move, which will compress the corresponding third spring. This process is repeated, allowing the rubber ball to intermittently impact the mixing tank and cause it to vibrate intermittently. Combined with the use of the cleaning scraper, the raw materials adhering to the inner wall of the mixing tank can be effectively scraped off, thus preventing the raw materials from sticking to the inner wall of the mixing tank. Step 5: After the raw materials are fully mixed, the first servo motor and the second servo motor can be turned off and the control valve can be opened, so that the mixed raw materials can be discharged from the mixing tank through the discharge pipe for subsequent processing.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting and using the mixing mechanism, the first mixing blade and the second mixing blade can rotate in opposite directions on the same axis, thereby enabling the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent to be fully and quickly mixed. 2. Under the coordinated action of the shaking mechanism, guide rail and guide slider, the mixing drum can be driven to perform intermittent reciprocating motion, thereby shaking the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent in the mixing drum, and further improving the mixing efficiency and mixing uniformity of the raw materials. 3. The striking mechanism allows the rubber ball to intermittently strike the mixing tank, causing it to vibrate intermittently. Combined with the cleaning scraper, it effectively removes the raw materials adhering to the inner wall of the mixing tank, thus preventing the raw materials from sticking to the inner wall.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1: As Figure 1-10As shown, this invention provides a device for preparing a water-reducing concrete agent with reduced adhesive content, including a supporting base plate 1. Symmetrically arranged U-shaped brackets 2 are fixedly installed on the top of the supporting base plate 1, and a mixing tank 3 is slidably installed on the side of the two U-shaped brackets away from the supporting base plate 1. A feed pipe 31 is connected to the upper end of the mixing tank 3, and a sealing cap 32 is detachably fitted onto the feed pipe 31. An array of anti-slip grooves is formed on the outer wall of the sealing cap 32, which increases friction and facilitates operation. A discharge pipe 33 is connected to the middle of the bottom of the mixing tank 3, and a control valve 34 is fixedly installed on the discharge pipe 33. A mixing mechanism 4 is fixedly installed at the end of the mixing tank 3 away from the supporting base plate 1, and a device for cooperating with the mixing tank 3 is fixedly installed on the top side of the supporting base plate 1. The shaking mechanism 5 has a supporting base plate 1 with a symmetrically distributed L-shaped bracket 6 fixedly connected to the end away from the shaking mechanism 5. The L-shaped bracket 6 is also fixedly connected to a transverse carrier plate 7 at the end away from the supporting base plate 1. A guide slide rail 21 is fixedly installed on the side of the U-shaped bracket 2 away from the supporting base plate 1. A guide slider 22 is slidably sleeved on the guide slide rail 21. The guide slider 22 is fixedly connected to the bottom end of the mixing tank 3. A limit baffle 23 is fixedly connected to the end of the guide slide rail 21 near the L-shaped bracket 6. The limit baffle 23 is fixedly connected to the U-shaped bracket 2, and the guide slider 22 can contact the limit baffle 23. Through the coordinated action of the guide slide rail 21 and the guide slider 22, the movement adjustment of the mixing tank 3 is limited and guided. The top of the transverse carrier plate 7 is provided with a striking mechanism 8 that works with the mixing tank 3.

[0026] The stirring mechanism 4 includes a first servo motor 41 and a fixed support 42. Both the first servo motor 41 and the fixed support 42 are fixedly installed at the top of the stirring tank 3. Symmetrically arranged first support rods 412 are fixedly installed at the top of the stirring tank 3, and the tops of the two first support rods 412 are fixedly connected to first fixed seats 413. The first servo motor 41 is fixedly inserted into the first fixed seats 413. The cooperation between the first support rods 412 and the first fixed seats 413 effectively improves the installation stability of the first servo motor 41. A first rotating rod 43 is fixedly connected to the output end of the first servo motor 41. The first rotating rod 43 is rotatably inserted into the stirring tank 3, and symmetrically arranged first stirring blades 44 are fixedly installed on the outer wall of the first rotating rod 43. The first rotating rod 43 is close to the first servo motor 41. One end of the mixing tank 3 is fixedly fitted with a first side gear 45. A second rotating rod 46 is rotatably inserted into the fixed support 42, and a connecting bevel gear 47 is fixedly fitted at the end of the second rotating rod 46. The connecting bevel gear 47 meshes with the first side gear 45. A rotating sleeve 48 is rotatably fitted onto the first rotating rod 43, and the rotating sleeve 48 is rotatably inserted into the top of the mixing tank 3. A second side gear 49 is fixedly fitted at the top of the rotating sleeve 48, and the second side gear 49 meshes with the connecting bevel gear 47. A symmetrically distributed cleaning scraper 410 is fixedly installed at the bottom of the rotating sleeve 48, and the outer wall of the cleaning scraper 410 is in contact with the inner wall of the mixing tank 3. An array of second stirring blades 411 is fixedly installed on the inner wall of the cleaning scraper 410, and the second stirring blades 411 and the first stirring blades 44 are staggered.

[0027] By adopting the above technical solution, during use, the first servo motor 41 will drive the first rotating rod 43 to rotate, thereby driving the first side gear 45 and the first stirring blade 44 to rotate. This, in turn, can cooperate with the use of the second rotating rod 46 to drive the connecting bevel gear 47 to rotate, and further drive the second side gear 49 to rotate in the opposite direction. At the same time as the second side gear 49 rotates in the opposite direction, it will drive the rotating sleeve 48 to rotate in the opposite direction, thereby driving the cleaning scraper 410 and the second stirring blade 411 to rotate in the opposite direction. This will enable the first stirring blade 44 and the second stirring blade 411 to rotate coaxially in opposite directions, thereby enabling the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent to be fully and quickly stirred.

[0028] The swaying mechanism 5 includes an L-shaped side rod 51, a U-shaped support 52, and a mounting bracket 53. The L-shaped side rod 51 is fixedly installed on the opposite side of the guide slider 22, and a movable slider 54 is fixedly connected to the end of the L-shaped side rod 51. A first spring 55 is fixedly installed on the side of the movable slider 54 away from the L-shaped bracket 6, and a connecting side block 56 is fixedly connected to the end of the first spring 55 away from the movable slider 54. The connecting side block 56 is fixedly connected to the U-shaped bracket 2. The U-shaped support 52 and the mounting bracket 53 are both fixedly connected to the support base plate 1, and the U-shaped support 53 is fixedly connected to the guide slider 2. A second servo motor 57 is fixedly installed on one side of the support 52. A rotating column 58 is fixedly connected to the output end of the second servo motor 57, and a third rotating rod 59 is slidably inserted into the inner cavity of the rotating column 58. The third rotating rod 59 movably passes through the U-shaped support 52, and a fixing collar 510 is fixedly sleeved on the end of the third rotating rod 59 away from the second servo motor 57. A guide push plate 511 is integrally formed on the outer wall of the fixing collar 510. An installation collar 512 is fixedly sleeved on the third rotating rod 59, and a fixing plate 511 is fixed on the outer wall of the installation collar 512. A second spring 513 is connected and movably sleeved on the third rotating rod 59. A mounting rotating ring 514 is fixedly connected to the end of the second spring 513 away from the mounting collar 512. The mounting rotating ring 514 is movably sleeved on the third rotating rod 59 and rotatably connected to the U-shaped support 52. A rotating sleeve 515 is rotatably inserted into the U-shaped support 52, and a take-up reel 516 is fixedly connected to the end of the rotating sleeve 515 away from the second servo motor 57. The third rotating rod 59 movably passes through the take-up reel 516. A limiting protrusion 517 is fixedly installed on the outer wall of the winding reel 516, and the guide push plate 511 can contact the limiting protrusion 517. A traction steel wire rope 518 is fixedly connected to the winding reel 516, and a U-shaped connecting rod 519 is fixedly connected to the end of the traction steel wire rope 518 that is wound around the lead-out end of the winding reel 516. The U-shaped connecting rod 519 is fixedly connected to the guide slider 22. A wedge-shaped protrusion 520 is fixedly installed on one side of the top of the mounting bracket 53, and the guide push plate 511 can make movable contact with the wedge-shaped protrusion 520.

[0029] By adopting the above technical solution, during use, the second servo motor 57 will drive the rotating column 58 to rotate, thereby driving the third rotating rod 59 to rotate, which in turn drives the guide push plate 511 to rotate through the fixed collar 510. When the guide push plate 511 contacts the limiting protrusion 517, it will drive the winding wheel 516 to rotate through the limiting protrusion 517, thereby gradually winding up the traction steel wire rope 518. Then, the traction steel wire rope 518 will drive the U-shaped connecting rod 519 to move away from the L-shaped bracket 6. Furthermore, the guide slider 22 will drive the mixing tank 3 and the L-shaped side rod 51 to move away from the L-shaped bracket 6. At the same time as the L-shaped side rod 51 moves, it will drive the moving slider 54 to move, thereby squeezing the corresponding first spring 55. When the guide push plate 511 contacts the wedge-shaped protrusion 520, it will move away from the winding wheel 516 under the action of the wedge-shaped protrusion 520, thereby driving the third rotating rod 516 through the fixed collar 510. The rotating rod 59 moves, which in turn moves the mounting collar 512 and squeezes the second spring 513. When the guide push plate 511 contacts the side of the wedge-shaped protrusion 520, the guide push plate 511 will separate from the limiting protrusion 517. At this time, the first spring 55 will push the moving slider 54 to reset, so that the mixing tank 3 can be reset through the cooperation of the L-shaped side rod 51 and the guide slider 22. Then, the winding wheel 516 can be reset and rotated through the traction wire rope 518. When the guide push plate 511 separates from the wedge-shaped protrusion 520, the second spring 513 will drive the third rotating rod 59 to reset through the mounting collar 512, so that the fixed collar 510 and the guide push plate 511 can be reset. Then, the above steps will be repeated, so that the mixing tank 3 can perform intermittent reciprocating motion, which can shake the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent in the mixing tank 3, thereby further improving the mixing efficiency and mixing uniformity of the raw materials.

[0030] The striking mechanism 8 includes a connecting gear 81, which is rotatably mounted on the transverse carrier plate 7 and is symmetrically distributed. A double-sided rack 82 and a single-sided rack 83 are meshed on the outer side of the connecting gear 81, and both the double-sided rack 82 and the single-sided rack 83 are slidably mounted on the transverse carrier plate 7. The double-sided rack 82 is fixedly connected to the mixing tank 3. A symmetrically arranged fourth rotating rod 810 is rotatably inserted into the transverse carrier plate 7, and the connecting gear 81 is rotatably sleeved on the fourth rotating rod 810. One end of the double-sided rack 82 is fixedly connected to a side connecting rod 811, and the side connecting rod 811 is fixedly connected to the mixing tank 3. The connection is made such that an L-shaped slide plate 84 is fixedly connected to one end of the rack 83 away from the mixing tank 3, a transverse slide rod 85 is slidably inserted on the L-shaped slide plate 84, and a rubber ball 86 is fixedly connected to one end of the transverse slide rod 85. The rubber ball 86 can contact the mixing tank 3, and a limiting disc 87 is fixedly installed on the other end of the transverse slide rod 85. A limiting ring 88 is fixedly sleeved on the transverse slide rod 85, and a third spring 89 is fixedly installed on the limiting ring 88. The third spring 89 is movably sleeved on the transverse slide rod 85, and the end of the third spring 89 away from the limiting ring 88 is fixedly connected to the L-shaped slide plate 84.

[0031] By adopting the above technical solution, when the mixing tank 3 moves away from the L-shaped support 6, the side connecting rod 811 will drive the double-sided rack 82 to move, thereby driving the single-sided rack 83 to move away from the mixing tank 3 via the connecting gear 81. This, in turn, will drive the corresponding transverse slide bar 85 to move via the L-shaped sliding plate 84. During this period, the third spring 89 will drive the transverse slide bar 85 to move closer to the mixing tank 3 via the limiting ring 88, thereby driving the rubber ball 86 to move. This will cause the rubber ball 86 to impact the mixing tank 3. Furthermore, during the later movement, when the limiting disc 87 and the L-shaped sliding plate 84... Upon contact, the rubber ball 86 will no longer move, and at this time, the rubber ball 86 will separate from the mixing tank 3. When the mixing tank 3 makes a reset movement, the mixing tank 3 will contact and impact the rubber ball 86. Then, the mixing tank 3 will move through the rubber ball 86 to drive the transverse slide bar 85 to squeeze the corresponding third spring 89. The above steps will be repeated, so that the rubber ball 86 will intermittently impact the mixing tank 3, thereby causing the mixing tank 3 to vibrate intermittently. In conjunction with the use of the cleaning scraper 410, the raw materials adhering to the inner wall of the mixing tank 3 can be effectively scraped off, thereby avoiding the phenomenon of raw materials adhering to the inner wall of the mixing tank 3.

[0032] Example 2: Figure 4 and Figure 7As shown, a symmetrically distributed second support rod 521 is fixedly installed on the U-shaped support 52, and a second fixed seat 522 is fixedly connected to the end of the second support rod 521. The second servo motor 57 is fixedly inserted into the second fixed seat 522. A transverse guide rod 523 is fixedly connected to the movable slider 54, and a connecting hole 524 is opened through the connecting side block 56. The transverse guide rod 523 is movably inserted into the inner side of the first spring 55, and the transverse guide rod 523 slides through the connecting hole 524.

[0033] By adopting the above technical solution, the installation stability of the second servo motor 57 is effectively improved under the coordinated action of the second support rod 521 and the second fixed seat 522, and the stable deformation of the first spring 55 is guaranteed by the cooperation of the transverse guide rod 523 and the connecting hole 524.

[0034] A method for preparing a binder-reducing concrete water-reducing agent preparation device includes the following steps: Step 1: Remove the sealing barrel cover 32, and then introduce the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent into the mixing barrel 3 through the feeding pipe 31. Then, reset the sealing barrel cover 32 and turn on the first servo motor 41 and the second servo motor 57. Step two: The first servo motor 41 drives the first rotating rod 43 to rotate, which in turn drives the first side gear 45 and the first stirring blade 44 to rotate. This, in turn, works with the second rotating rod 46 to drive the connecting bevel gear 47 to rotate, which in turn drives the second side gear 49 to rotate in the opposite direction. At the same time as the second side gear 49 rotates in the opposite direction, it drives the rotating sleeve 48 to rotate in the opposite direction, which in turn drives the cleaning scraper 410 and the second stirring blade 411 to rotate in the opposite direction. This allows the first stirring blade 44 and the second stirring blade 411 to rotate coaxially in opposite directions, thereby enabling the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent to be fully and quickly stirred. Step three, simultaneously, the second servo motor 57 drives the rotating column 58 to rotate, which in turn drives the third rotating rod 59 to rotate. This, in turn, drives the guide push plate 511 to rotate via the fixed collar 510. When the guide push plate 511 contacts the limiting protrusion 517, it drives the winding wheel 516 to rotate via the limiting protrusion 517, thus gradually winding up the traction wire rope 518. This, in turn, drives the U-shaped connecting rod 519 to move away from the L-shaped bracket 6 via the traction wire rope 518. Furthermore, the guide slider 22 drives the mixing tank 3 and the L-shaped side rod 51 to move away from the L-shaped bracket 6. Simultaneously, the L-shaped side rod 51 moves, driving the moving slider 54 to move, thus compressing the corresponding first spring 55. When the guide push plate 511 contacts the wedge-shaped protrusion 520, it moves away from the winding wheel 516 under the action of the wedge-shaped protrusion 520, thereby driving the third rotating rod 511 via the fixed collar 510. 9. The movement of the guide push plate 511 causes the mounting collar 512 to move and compress the second spring 513. When the guide push plate 511 contacts the side of the wedge-shaped protrusion 520, the guide push plate 511 will separate from the limiting protrusion 517. At this time, the first spring 55 will push the moving slider 54 to reset, thereby driving the mixing tank 3 to reset through the cooperation of the L-shaped side rod 51 and the guide slider 22. Then, the winding wheel 516 can be reset and rotated through the traction wire rope 518. When the guide push plate 511 separates from the wedge-shaped protrusion 520, the second spring 513 will drive the third rotating rod 59 to reset through the mounting collar 512, thereby driving the fixed collar 510 and the guide push plate 511 to reset. The above steps will be repeated, thereby driving the mixing tank 3 to perform intermittent reciprocating motion, thereby shaking the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent in the mixing tank 3, thereby further improving the mixing efficiency and mixing uniformity of the raw materials. Step four: When the mixing tank 3 moves away from the L-shaped support 6, the side connecting rod 811 drives the double-sided rack 82 to move, which in turn drives the single-sided rack 83 to move away from the mixing tank 3 via the connecting gear 81. This, in turn, drives the corresponding transverse slide bar 85 to move via the L-shaped sliding plate 84. During this process, the third spring 89 drives the transverse slide bar 85 to move closer to the mixing tank 3 via the limiting ring 88, which in turn drives the rubber ball 86 to move. This causes the rubber ball 86 to impact the mixing tank 3. Later, when the limiting disc 87 contacts the L-shaped sliding plate 84, the rubber ball... The rubber ball 86 will no longer move. At this time, the rubber ball 86 will separate from the mixing tank 3. When the mixing tank 3 makes a reset movement, the mixing tank 3 will come into contact with the rubber ball 86. Then the mixing tank 3 will move through the rubber ball 86 to drive the transverse slide bar 85 to squeeze the corresponding third spring 89. The above steps will be repeated so that the rubber ball 86 will intermittently hit the mixing tank 3, thereby causing the mixing tank 3 to vibrate intermittently. In conjunction with the use of the cleaning scraper 410, the raw materials attached to the inner wall of the mixing tank 3 can be effectively scraped off, thereby avoiding the phenomenon of raw materials adhering to the inner wall of the mixing tank 3. Step 5: After the raw materials are fully mixed, the first servo motor 41 and the second servo motor 57 can be turned off and the control valve 34 can be opened, so that the mixed raw materials can be discharged from the mixing tank 3 through the discharge pipe 33 and carried out subsequent processing operations.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.

8. A method for preparing a binder-reducing concrete water-reducing agent preparation device, characterized in that, Includes the following steps: Step 1: Remove the sealing barrel cover (32), and then introduce the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent into the mixing barrel (3) through the feeding pipe (31). Then, reset the sealing barrel cover (32) and turn on the first servo motor (41) and the second servo motor (57). Step 2: The first servo motor (41) will drive the first rotating rod (43) to rotate, thereby driving the first side gear (45) and the first stirring blade (44) to rotate. In turn, it can cooperate with the use of the second rotating rod (46) to drive the connecting bevel gear (47) to rotate, and further drive the second side gear (49) to rotate in the opposite direction. At the same time as the second side gear (49) rotates in the opposite direction, it will drive the rotating sleeve (48) to rotate in the opposite direction, thereby driving the cleaning scraper (410) and the second stirring blade (411) to rotate in the opposite direction. This will enable the first stirring blade (44) and the second stirring blade (411) to rotate in the opposite direction on the same axis, thereby enabling the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent to be fully and quickly stirred. Step three, simultaneously, the second servo motor (57) will drive the rotating column (58) to rotate, thereby driving the third rotating rod (59) to rotate, which in turn drives the guide push plate (511) to rotate through the fixed collar (510). When the guide push plate (511) contacts the limiting protrusion (517), it will drive the winding wheel (516) to rotate through the limiting protrusion (517), thereby gradually winding up the traction wire rope (518), and then driving the U-shaped connecting rod (519) away from L through the traction wire rope (518). The movement of one side of the L-shaped support (6) can further drive the mixing tank (3) and the L-shaped side rod (51) to move away from the L-shaped support (6) via the guide slider (22). At the same time as the L-shaped side rod (51) moves, it will drive the moving slider (54) to move, thereby squeezing the corresponding first spring (55). When the guide push plate (511) contacts the wedge-shaped protrusion (520), it will move away from the winding wheel (516) under the action of the wedge-shaped protrusion (520), thereby driving the third rotation via the fixed collar (510). The rod (59) moves, which in turn moves the mounting collar (512) and squeezes the second spring (513). When the guide push plate (511) contacts the side of the wedge-shaped protrusion (520), the guide push plate (511) will separate from the limiting protrusion (517). At this time, the first spring (55) will push the moving slider (54) to reset. Thus, the mixing tank (3) can be reset by the cooperation of the L-shaped side rod (51) and the guide slider (22). Then, the winding wheel (516) can be driven to move by the traction wire rope (518). When the guide push plate (511) separates from the wedge-shaped protrusion (520), the second spring (513) will drive the third rotating rod (59) to reset through the mounting collar (512), thereby driving the fixed collar (510) and the guide push plate (511) to reset. Then the above steps will be repeated, thereby driving the mixing tank (3) to perform intermittent reciprocating motion, thereby shaking the raw materials required for the preparation of the adhesive-reducing concrete water-reducing agent in the mixing tank (3), thereby further improving the mixing efficiency and mixing uniformity of the raw materials. Step four: When the mixing tank (3) moves away from the L-shaped support (6), the side connecting rod (811) will drive the double racks (82) to move, thereby driving the single rack (83) away from the mixing tank (3) through the connecting gear (81). In turn, the L-shaped slide plate (84) will drive the corresponding transverse slide bar (85) to move. During this period, the third spring (89) will drive the transverse slide bar (85) to move closer to the mixing tank (3) through the limiting ring (88), thereby driving the rubber ball (86) to move, and thus causing the rubber ball (86) to hit the mixing tank (3). In the later movement, when the limiting disc (87) contacts the L-shaped slide plate (84) When the rubber ball (86) stops moving, it will separate from the mixing tank (3). When the mixing tank (3) makes a reset movement, it will contact and impact the rubber ball (86). Then the mixing tank (3) will move through the rubber ball (86) and drive the transverse slide bar (85) to squeeze the corresponding third spring (89). The above steps will be repeated so that the rubber ball (86) can intermittently impact the mixing tank (3), which will cause the mixing tank (3) to vibrate intermittently. With the use of the cleaning scraper (410), the raw materials attached to the inner wall of the mixing tank (3) can be effectively scraped off, thus avoiding the phenomenon of raw materials adhering to the inner wall of the mixing tank (3). Step 5: After the raw materials are fully mixed, the first servo motor (41) and the second servo motor (57) can be turned off and the control valve (34) can be opened, so that the mixed raw materials can be discharged from the mixing tank (3) through the discharge pipe (33) and carried out subsequent processing operations.
