A cover is provided on the top wall of the mixing tank, and a motor is fixedly connected to the top of the cover. The output end of the motor is located inside the mixing tank, and a connecting block is fixedly connected to the output end of the motor. A first gear ring is fixedly connected to the inner wall of the mixing tank, and several mixing units are arranged on the connecting block.

Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, and in particular relates to a water conservancy engineering construction device. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering projects. Water conservancy projects require the construction of different types of hydraulic structures such as dams, spillways, sluice gates, water intakes, canals, ferries, rafts, and fishways to achieve their goals.

[0003] Concrete is required when constructing dams, dikes, and other structures in water conservancy projects. Concrete is a major component of real buildings, and its performance directly affects the safety of the building. Most concrete mixers on the market have a fixed mixing shaft, which is driven to rotate by a motor. This causes the mixing rod connected to the mixing shaft to move axially, mixing the materials in the mixing tank. Existing concrete mixers generally suffer from low mixing efficiency and uneven mixing. Summary of the Invention

[0004] In view of this, the present invention aims to provide a hydraulic engineering construction device to solve the problems of low mixing efficiency and uneven mixing in existing concrete mixers.

Several stirring groups are provided on the support rod, and the several stirring groups are arranged at equal distances along the support rod in the vertical direction.

[0008] Furthermore, the mixing assembly includes a second gear, which is rotatably connected inside the support rod. Both ends of the rotating shaft of the second gear are fixedly connected to U-shaped rods. A number of teeth are provided on one side of the second gear, and the teeth are fixedly connected to the drive rod. The teeth can mesh with the second gear. The U-shaped rods are rotatably connected to stirring blades.

[0009] Furthermore, the transmission assembly is used to drive several of the stirring blades to rotate and stir.

[0010] Furthermore, as a further embodiment of the present invention, the transmission assembly includes a plurality of annular components corresponding one-to-one with the number of second gears. Each annular component is fixedly connected to two U-shaped rods. The interior of each annular component is hollow. Two fourth gears are rotatably connected to the inner wall of each annular component. The two fourth gears are located above the two stirring blades. The rotation shaft of each pair of fourth gears passes through the annular component outside and is fixedly connected to the two stirring blades located below them. Each pair of fourth gears meshes with a second gear ring. Each second gear ring is slidably connected to the annular component and is an incomplete gear. Each second gear ring is rotatably connected to a sliding plate. A plurality of sliding plates are slidably connected to a first support rod. Each sliding plate can slide along the first support rod in the vertical direction.

[0011] Furthermore, the transmission assembly also includes a rotation assembly, which is used to drive the first support rod to rotate at a certain angle.

[0012] As a further embodiment of the present invention, the rotating assembly includes a second push rod and a limiting disk. The second push rod is fixedly connected to the rotation shaft of the first gear. The limiting disk is fixedly connected to the outer wall of the support rod. The limiting disk has a limiting groove, and a slider is slidably connected inside the limiting groove.

[0016] As a further embodiment of the present invention, a support base is fixedly connected to the bottom of the mixing tank.

[0017] A construction method for a water conservancy project, comprising the following steps:

[0018] Step 1: When the motor rotates, the connecting parts drive the support rod to move, which in turn mixes the concrete through the mixing blades;

[0019] Step 2: When the connector moves, the first push rod rotates, which then indirectly drives the drive rod to rise and fall, causing the stirring blades to tilt.

[0020] Step 3: Drive the mixing unit through the transmission unit to accelerate the mixing efficiency;

[0021] Step 4: When the second push rod rotates, it can drive the first support rod to rotate, thereby changing the rotation direction of the stirring blade.

[0022] Compared with the prior art, the water conservancy engineering construction device of the present invention has the following beneficial effects:

[0023] 1. After the concrete and water have been mixed for a certain period of time, the concrete is subjected to mixing force in different directions by the back-and-forth movement of the connector. Furthermore, the up-and-down and left-and-right tilting directions of the mixing blades are opposite as the connector moves from the inside to the outside and from the outside to the inside, thus avoiding layering differences and improving mixing efficiency.

[0024] 2. During the mixing process of concrete and water, the continuous up-and-down and left-and-right tilting of the mixing blades can effectively break down the concrete. This not only accelerates the mixing of water and concrete materials but also improves mixing efficiency and prevents the concrete from clumping during axial mixing.

[0025] 3. Because the rotation direction of the first gear is opposite during the process of the connector sliding from the inside to the outside and the process of the connector sliding from the outside to the inside, the direction of the tilt of the stirring blade is opposite during the process of the connector sliding from the inside to the outside and the process of the connector sliding from the outside to the inside. The direction of the inclination of the transmission group driving the mixing group also changes accordingly, thereby making the mixing efficiency higher. Attached Figure Description

[0047] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] Please see Figure 1-15 The present invention provides a technical solution: a water conservancy engineering construction device, including a mixing tank 1, a cover is provided on the top wall of the mixing tank 1, a motor 2 is fixedly connected to the top of the cover, the output end of the motor 2 is located inside the mixing tank 1, a connecting block 3 is fixedly connected to the output end of the motor 2, a first gear ring 4 is fixedly connected to the inner wall of the mixing tank 1, and a plurality of mixing groups are provided on the connecting block 3.

[0049] The stirring assembly includes a transmission assembly and a limiting rod 5. The limiting rod 5 is fixedly connected to the connecting block 3. The limiting rod 5 is slidably connected to a connecting piece 6. The connecting piece 6 is threadedly connected to a reciprocating screw 21. One end of the reciprocating screw 21 is rotatably connected to the connecting block 3, and the other end of the reciprocating screw 21 is fixedly connected to a third gear 22, which can mesh with a first gear ring 4. The connecting piece 6 is rotatably connected to a first gear 7, which meshes with a first rack rod 8. The first gear 7 is fixedly connected to a U-shaped first push rod 23. The first rack rod 8 is fixedly connected to the side wall of the limiting rod 5. The bottom end of the connecting piece 6 is fixedly connected to a support rod 9. The rod 9 has a notch, and a drive rod 10 is slidably connected inside the support rod 9; the drive rod 10 is fixedly connected to a first spring 11 for its reset, and a drive frame 12 is fixedly connected to the drive rod 10. A first lifting plate 13 and a second lifting plate 14 are rotatably connected to the left and right side walls of the drive frame 12, respectively. A torsion spring 15 is sleeved on the rotation shaft of the first lifting plate 13 and the second lifting plate 14. A card 16 is provided above the first lifting plate 13 and the second lifting plate 14. Both cards 16 are fixedly connected to the drive frame 12. Several stirring groups are provided on the support rod 9, and the several stirring groups are arranged at equal distances in the vertical direction along the support rod 9.

[0050] The mixing assembly includes a second gear 17, which is rotatably connected inside the support rod 9. Both ends of the rotating shaft of the second gear 17 are fixedly connected to U-shaped rods 18. A plurality of teeth 19 are provided on one side of the second gear 17. The plurality of teeth 19 are fixedly connected to the drive rod 10 and can mesh with the second gear 17. The U-shaped rods 18 are rotatably connected to stirring blades 20.

[0051] The transmission assembly is used to drive several of the stirring blades 20 to rotate and stir.

[0052] In the above scheme, concrete and water are put into the mixing tank 1, and then the motor 2 is started. When the motor 2 is working, it drives the connecting block 3 to rotate. When the connecting block 3 rotates, it drives the limiting rod 5 to rotate. When the limiting rod 5 rotates, the third gear 22 will mesh with the first gear ring 4. The third gear 22 drives the reciprocating screw 21 to rotate, so that the connecting piece 6 slides from the inside to the outside along the limiting rod 5.

[0053] When the connector 6 slides from the inside out, it drives the first gear 7 to move. When the first gear 7 meshes with the first rack 8, it drives the first push rod 23 to rotate counterclockwise. The first push rod 23 is U-shaped. When the first push rod 23 rotates, one end of it continues to rotate after reaching the top and contacts the top surface of the first lifting plate 13, pressing down on the first lifting plate 13. Since the first lifting plate 13 is rotatably connected to the drive frame 12, when the first push rod 23 presses down on the first lifting plate 13, the first lifting plate 13 will directly rotate around the rotating shaft and compress the torsion spring 15, thereby allowing the first lifting plate 13 to make way for the first push rod 23. When the other end of the first push rod 23 contacts the bottom of the second lifting plate 14, it will lift the second lifting plate 14 from the bottom. When the first push rod 23 lifts the second lifting plate 14, the second lifting plate 14 will move towards... The second lifting plate 14 is unable to rotate under the action of the torsion spring 15 and the card 16. Therefore, after the first push rod 23 pushes the second lifting plate 14 upward, the second lifting plate 14 will drive the drive frame 12 and the drive rod 10 to rise until the end of the first push rod 23 passes over the bottom wall of the second lifting plate 14 and then the second lifting plate 14 will return to its original position. When the drive rod 10 rises, it will slide along the support rod 9 and compress the first spring 11. When the drive rod 10 rises, it will drive several teeth 19 to mesh with the second gear 17. When the second gear 17 rotates, it will drive the two U-shaped rods 18 and the stirring blade 20 to rotate at a certain angle, so that the U-shaped rods 18 drive the stirring blade 20 to tilt in the up and down direction. The transmission group drives the stirring blade 20 to tilt in the left and right direction based on the tilt of the U-shaped rods 18.

[0054] During the process of the connector 6 sliding from the inside to the outside, the reciprocating screw 21 drives the connector 6 to move from the inside to the outside. During this process, the first gear 7 will rotate continuously, and the first push rod 23 will continuously push the second lifting plate 14 upward, so that several U-shaped rods 18 and mixing blades 20 will rotate intermittently from the vertical state to the vertical direction. The transmission group drives the mixing blades 20 to tilt left and right based on the tilt of the U-shaped rods 18. This makes the mixing blades 20 more efficient when initially mixing concrete and water, and can perform multi-directional alternating mixing of concrete, so that water and concrete raw materials can be mixed faster.

[0055] When the connector 6 slides from the outside to the inside, the first gear 7 will still mesh with the first rack 8. However, the rotation direction of the first gear 7 is opposite to that of the connector 6 sliding from the inside to the outside. During the process of the connector 6 sliding from the inside to the outside, the first push rod 23 presses down on the first lifting plate 13 and lifts up the second lifting plate 14. The drive rod 10 and the drive frame 12 descend. During the process of the connector 6 sliding from the outside to the inside, the first push rod 23 will contact the first lifting plate 13 from below. At this time, the first lifting plate 13 is blocked by the card 16 and cannot rotate, thereby driving the drive frame 12 and the drive rod 10 to rise. After the first push rod 23 passes the first lifting plate 13, The first spring 11 drives the drive frame 12 and drive rod 10 to reset. At this time, the first lifting plate 13 and the second lifting plate 14 are reset. Then the first push rod 23 will contact the second lifting plate 14 from the top. At this time, the second lifting plate 14 will rotate around the rotating shaft, so that the first push rod 23 passes over the second lifting plate 14. Since the rotation direction of the first gear 7 is opposite to that of the connecting piece 6 sliding from the inside to the outside, the tilting direction of the stirring blade 20 is opposite to that of the connecting piece 6 sliding from the inside to the outside. The tilting direction of the transmission group driving the stirring group also changes accordingly, thus making the stirring efficiency higher.

[0056] After the concrete and water have been mixed for a certain period of time, the concrete is subjected to mixing force in different directions by the back-and-forth movement of the connector 6. Furthermore, the up-and-down and left-and-right tilting directions of the mixing blades 20 are opposite as the connector 6 moves from the inside to the outside and from the outside to the inside, thus avoiding layering differences and improving mixing efficiency.

[0057] During the mixing process of concrete and water, the constant up-and-down and left-and-right tilting of the mixing blades 20 can effectively break down the concrete. This not only accelerates the mixing of water and concrete materials but also improves the mixing efficiency and prevents the concrete from clumping during axial mixing.

[0058] When the connector 6 slides from the inside to the outside to its limit position, the reciprocating screw 21 will drive the connector 6 to slide from the outside to the inside. During the process of the connector 6 sliding from the inside to the outside, the reciprocating screw 21 drives the connector 6 to move from the inside to the outside. During this process, the first gear 7 will rotate continuously, and the first push rod 23 will continuously push the second lifting plate 14 upward, so that several U-shaped rods 18 and mixing blades 20 will rotate intermittently from a vertical state to an upward and downward tilting state. The transmission group drives the mixing blades 20 to tilt left and right based on the tilting of the U-shaped rods 18, so that the mixing blades 20 are more efficient when initially mixing concrete and water, and can perform multi-directional alternating mixing of concrete, so that water and concrete raw materials can be mixed faster.

[0059] As a further embodiment of the present invention, the transmission assembly includes a plurality of annular components 34 corresponding one-to-one with the number of second gears 17. Each annular component 34 is fixedly connected to two U-shaped rods 18. The interior of each annular component 34 is hollow. Two fourth gears 35 are rotatably connected to the inner wall of each annular component 34. The two fourth gears 35 are located above the two stirring blades 20. The rotation shaft of each pair of fourth gears 35 passes through the annular component 34 and is fixedly connected to the two stirring blades 20 located below them. Each pair of fourth gears 35 meshes with a second gear ring 36. Each second gear ring 36 is slidably connected to the annular component 34 and is an incomplete gear. Each second gear ring 36 is rotatably connected to a sliding piece 37. A plurality of sliding pieces 37 are slidably connected to a first support rod 32. Each sliding piece 37 can slide along the first support rod 32 in the vertical direction.

[0060] The transmission assembly also includes a rotation assembly, which is used to drive the first support rod 32 to rotate at a certain angle.

[0061] When the above-mentioned transmission assembly is working, when the connecting piece 6 slides along the limiting rod 5, the rotating assembly will drive the first support rod 32 to rotate intermittently to the left and right around the support rod 9. When the first support rod 32 rotates to the left or right, it will drive several sliding pieces 37 to rotate accordingly. When the sliding pieces 37 rotate, they will drive the second gear ring 36 to rotate. When the second gear ring 36 rotates, it will mesh with two fourth gears 35 respectively. When the fourth gears 35 rotate, they will drive the stirring blade 20 to rotate in the left and right directions. Since the sliding pieces 37 can slide along the first support rod 32 in the up and down directions, when the drive rod 10 rises or falls and causes the U-shaped rod 18 to tilt, the U-shaped rod 18 will drive the ring piece 34 to rotate. When the ring piece 34 rotates, it will drive the second gear ring 36 to rotate. When the second gear ring 36 rotates, the sliding pieces 37 will slide up or down along the first support rod 32, so as not to hinder the rotation driven by the first support rod 32.

[0062] During the process of the connector 6 sliding from the inside to the outside, the reciprocating screw 21 drives the connector 6 to move from the inside to the outside. During this process, the first gear 7 will rotate continuously, and the first push rod 23 will continuously push the second lifting plate 14 upward, so that several U-shaped rods 18 and mixing blades 20 will rotate intermittently from the vertical state to the vertical direction. The transmission group drives the mixing blades 20 to tilt left and right based on the tilt of the U-shaped rods 18. This makes the mixing blades 20 more efficient when initially mixing concrete and water, and can perform multi-directional alternating mixing of concrete, so that water and concrete raw materials can be mixed faster.

[0063] The annular component 34 can protect the second toothed ring 36 and prevent cement from entering the annular component 34. The slot opened inside the first support rod 32 can meet the sliding of the sliding piece 37 and also prevent cement from entering the slot.

[0064] As a further embodiment of the present invention, the rotating assembly includes a second push rod 24 and a limiting disk 25. The second push rod 24 is fixedly connected to the rotation shaft of the first gear 7. The limiting disk 25 is fixedly connected to the outer wall of the support rod 9. The limiting disk 25 has a limiting groove 26. A slider 27 is slidably connected inside the limiting groove 26. A second spring 28 is provided on both sides of the slider 27. Both second springs 28 are fixedly connected to the inner wall of the limiting groove 26. An arc-shaped plate 29 is fixedly connected to the bottom end of the slider 27. A contact plate 30 is fixedly connected to the arc-shaped plate 29. The second push rod 24 can push the contact plate 30 to rotate. A crossbar 31 is fixedly connected to the bottom of the contact plate 30. A second support rod 38 is slidably connected to the crossbar 31. A third spring 33 for resetting is fixedly connected to both sides of the second support rod 38. The second support rod 38 is slidably connected to the outside of the first support rod 32.

[0065] In operation, the first gear 7 rotates its shaft, causing the second push rod 24 to rotate. When one end of the second push rod 24 rotates to a position where it contacts the contact plate 30, it will contact the contact plate 30 and push it. The contact plate 30, after being pushed, will cause the arc plate 29 and the crossbar 31 to rotate. When the arc plate 29 rotates, the slider 27 slides along the limiting groove 26 opened in the limiting plate 25, and compresses the second spring 28 during sliding. When the second push rod 24 pushes the contact plate 30 to rotate to a certain extent, the contact plate 30 will disengage from the second push rod 24. At this time, Under the action of the second spring 28, the contact plate 30 can be reset. When the crossbar 31 slides, it drives the second support rod 38 to move. The second support rod 38 is slidably connected to the first support rod 32. Therefore, when the second push rod 24 pushes the contact plate 30 to rotate left and right, the second support rod 38 can drive the first support rod 32 to rotate left and right, thereby causing the second gear ring 36 to rotate left and right, and thus causing the stirring blade 20 to tilt left and right. Since the second push rod 24 is fixedly connected to the rotating shaft of the first gear 7, when the first gear 7 rotates forward or backward, the second push rod 24 will also rotate, thereby causing the contact plate 30 to rotate back and forth.

[0066] When the second gear 17 drives the U-shaped rod 18 to rotate, the ring part 34 will also rotate upward or downward. The second gear ring 36 drives the sliding plate 37 to slide up and down, and also pulls the first support rod 32 to slide along the crossbar 31. The second spring 28 is used to drive the first support rod 32 to reset.

[0067] As a further embodiment of the present invention, a sealing disc 39 is fixedly connected to the outside of the slider 27.

[0068] When the above solution is in operation, the sealing disc 39 can prevent concrete from entering the limiting groove 26.

[0069] As a further embodiment of the present invention, the mixing tank 1 has a discharge port 40 on its side wall.

[0070] As a further embodiment of the present invention, a feeding frame 41 is fixedly connected to the side wall of the mixing tank 1.

[0071] As a further embodiment of the present invention, a support base 42 is fixedly connected to the bottom of the mixing tank 1.

[0072] The above scheme does not support the mixing tank 1 through the support base 42 during operation, but feeds through the feeding frame 41 and discharges through the discharge port 40.

[0073] A construction method for a water conservancy project, comprising the following steps:

[0074] Step 1: When the motor 2 rotates, the connecting piece 6 drives the support rod 9 to move, which in turn mixes the concrete through the mixing blades 20;

[0075] Step 2: When the connector 6 moves, the first push rod 23 rotates, and then indirectly drives the drive rod 10 to rise and fall, causing the stirring blade 20 to tilt.

[0076] Step 3: Drive the mixing unit through the transmission unit to accelerate the mixing efficiency;

[0077] Step 4: When the second push rod 24 rotates, it can drive the first support rod 32 to rotate, thereby changing the rotation direction of the stirring blade 20.

[0078] Working principle: Concrete and water are put into the mixing tank 1, and then the motor 2 is started. When the motor 2 is working, it drives the connecting block 3 to rotate. When the connecting block 3 rotates, it drives the limiting rod 5 to rotate. When the limiting rod 5 rotates, the third gear 22 will mesh with the first gear ring 4. The third gear 22 drives the reciprocating screw 21 to rotate, so that the connecting piece 6 slides from the inside to the outside along the limiting rod 5.

[0079] When the connector 6 slides from the inside out, it drives the first gear 7 to move. When the first gear 7 meshes with the first rack 8, it drives the first push rod 23 to rotate counterclockwise. The first push rod 23 is U-shaped. When the first push rod 23 rotates, one end of it continues to rotate after reaching the top and contacts the top surface of the first lifting plate 13, pressing down on the first lifting plate 13. Since the first lifting plate 13 is rotatably connected to the drive frame 12, when the first push rod 23 presses down on the first lifting plate 13, the first lifting plate 13 will directly rotate around the rotating shaft and compress the torsion spring 15, thereby allowing the first lifting plate 13 to make way for the first push rod 23. When the other end of the first push rod 23 contacts the bottom of the second lifting plate 14, it will lift the second lifting plate 14 from the bottom. When the first push rod 23 lifts the second lifting plate 14, the second lifting plate 14 will move towards... The second lifting plate 14 is unable to rotate under the action of the torsion spring 15 and the card 16. Therefore, after the first push rod 23 pushes the second lifting plate 14 upward, the second lifting plate 14 will drive the drive frame 12 and the drive rod 10 to rise until the end of the first push rod 23 passes over the bottom wall of the second lifting plate 14 and then the second lifting plate 14 will return to its original position. When the drive rod 10 rises, it will slide along the support rod 9 and compress the first spring 11. When the drive rod 10 rises, it will drive several teeth 19 to mesh with the second gear 17. When the second gear 17 rotates, it will drive the two U-shaped rods 18 and the stirring blade 20 to rotate at a certain angle, so that the U-shaped rods 18 drive the stirring blade 20 to tilt in the up and down direction. The transmission group drives the stirring blade 20 to tilt in the left and right direction based on the tilt of the U-shaped rods 18.

[0080] During the process of the connector 6 sliding from the inside to the outside, the reciprocating screw 21 drives the connector 6 to move from the inside to the outside. During this process, the first gear 7 will rotate continuously, and the first push rod 23 will continuously push the second lifting plate 14 upward, so that several U-shaped rods 18 and mixing blades 20 will rotate intermittently from the vertical state to the vertical direction. The transmission group drives the mixing blades 20 to tilt left and right based on the tilt of the U-shaped rods 18. This makes the mixing blades 20 more efficient when initially mixing concrete and water, and can perform multi-directional alternating mixing of concrete, so that water and concrete raw materials can be mixed faster.

[0081] When the connector 6 slides from the outside to the inside, the first gear 7 will still mesh with the first rack 8. However, the rotation direction of the first gear 7 is opposite to that of the connector 6 sliding from the inside to the outside. During the process of the connector 6 sliding from the inside to the outside, the first push rod 23 presses down on the first lifting plate 13 and lifts up the second lifting plate 14. The drive rod 10 and the drive frame 12 descend. During the process of the connector 6 sliding from the outside to the inside, the first push rod 23 will contact the first lifting plate 13 from below. At this time, the first lifting plate 13 is blocked by the card 16 and cannot rotate, thereby driving the drive frame 12 and the drive rod 10 to rise. After the first push rod 23 passes the first lifting plate 13, The first spring 11 drives the drive frame 12 and drive rod 10 to reset. At this time, the first lifting plate 13 and the second lifting plate 14 are reset. Then the first push rod 23 will contact the second lifting plate 14 from the top. At this time, the second lifting plate 14 will rotate around the rotating shaft, so that the first push rod 23 passes over the second lifting plate 14. Since the rotation direction of the first gear 7 is opposite to that of the connecting piece 6 sliding from the inside to the outside, the tilting direction of the stirring blade 20 is opposite to that of the connecting piece 6 sliding from the inside to the outside. The tilting direction of the transmission group driving the stirring group also changes accordingly, thus making the stirring efficiency higher.

[0082] After the concrete and water have been mixed for a certain period of time, the concrete is subjected to mixing force in different directions by the back-and-forth movement of the connector 6. Furthermore, the up-and-down and left-and-right tilting directions of the mixing blades 20 are opposite as the connector 6 moves from the inside to the outside and from the outside to the inside, thus avoiding layering differences and improving mixing efficiency.

[0083] During the mixing process of concrete and water, the constant up-and-down and left-and-right tilting of the mixing blades 20 can effectively break down the concrete. This not only accelerates the mixing of water and concrete materials but also improves the mixing efficiency and prevents the concrete from clumping during axial mixing.

[0084] When the connector 6 slides from the inside to the outside to its limit position, the reciprocating screw 21 will drive the connector 6 to slide from the outside to the inside. During the process of the connector 6 sliding from the inside to the outside, the reciprocating screw 21 drives the connector 6 to move from the inside to the outside. During this process, the first gear 7 will rotate continuously, and the first push rod 23 will continuously push the second lifting plate 14 upward, so that several U-shaped rods 18 and mixing blades 20 will rotate intermittently from a vertical state to an upward and downward tilting state. The transmission group drives the mixing blades 20 to tilt left and right based on the tilting of the U-shaped rods 18, so that the mixing blades 20 are more efficient when initially mixing concrete and water, and can perform multi-directional alternating mixing of concrete, so that water and concrete raw materials can be mixed faster.
