Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, in particular to a concrete production device for water conservancy engineering. Background Art

[0002] In water conservancy projects, concrete is an extremely important building material with wide and critical applications. Hydraulic concrete is widely used in various types of dam construction, hydropower station construction, waterways, ship locks, docks and other engineering construction. These buildings need to withstand huge water pressure and geological stress, so concrete is required to have high strength, high impermeability, high freeze-thaw resistance and other properties.

[0003] The particle size of concrete used in water conservancy projects is relatively large. Since many water conservancy projects are large-scale projects, the requirements for aggregates are different from those of ordinary concrete. The particle size of aggregates is relatively large, and the maximum aggregate particle size can reach 15 cm. It also accounts for a very high proportion. Basically, aggregates with a particle size of 8 to 15 cm can account for about 1 / 3 of the total aggregate. The particle size of general concrete is smaller. The aggregate particle size of ordinary concrete is relatively small, generally below 4 cm, and the aggregate particle size of some cement products is even smaller, basically below 2 cm.

[0004] After searching, a concrete mixing device for water conservancy engineering construction bridges with application number 202022825639.7 is found. The bottom of the support plate is connected to a first motor, the top of the first motor is connected to a first stirring rod, and the surface of the first stirring rod is connected to a spiral stirring blade, which rotates to stir the concrete raw materials.

[0005] In the existing technical solutions, cement, aggregate, water and other materials are mostly mixed and stirred by a mixing main machine. During the mixing process, the mixing blades in the mixing main machine continuously turn over and stir the materials to make them fully mixed and uniform. However, the particle size of concrete aggregate for water conservancy projects is larger than that of general concrete aggregate. Therefore, during the concrete mixing process, large particles of concrete aggregate will be crushed due to mutual extrusion, and then large particles of concrete aggregate will be transformed into small particles of aggregate. Therefore, the density and compressive strength of concrete for water conservancy projects will be reduced, and the construction requirements of water conservancy projects cannot be met. Summary of the invention

[0006] The purpose of the present invention is to provide a concrete production device for water conservancy projects, in which the vibrating assembly makes the aggregates and cement slurry in the concrete more evenly distributed through vibration, thereby reducing the gaps and accumulation between the aggregates; this uniform distribution helps the aggregates to remain stable in the concrete, reduces the crushing caused by mutual squeezing, thereby improving the bearing capacity of the overall structure, and further ensuring the density, compressive resistance and impermeability of the concrete, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a concrete production device for water conservancy engineering, comprising a mixing tank, a raw material filling port is provided at the top of the mixing tank, a discharge valve pipe is connected to the middle position of the bottom end surface of the mixing tank, a servo motor is fixedly installed at the top of the mixing tank, a transmission shaft is fixedly installed at the output end of the servo motor, a driving assembly is provided at the upper end of the outer wall of the transmission shaft, and a vibrating assembly is provided at the power output end of the driving assembly;

[0008] The vibration assembly includes a vibration assembly seat fixedly mounted on the side wall of the mixing tank, a vibration rod is slidably mounted inside the vibration assembly seat, two limit grooves are provided inside the vibration assembly seat, a connecting plate and a reset spring are installed inside the limit groove, the upper end of the reset spring is fixed on the inner upper wall of the limit groove, the lower end of the reset spring is fixedly connected to the upper end surface of the connecting plate, and the end of the connecting plate away from the limit groove is fixedly connected to the side wall of the vibration rod.

[0009] Preferably, the driving assembly comprises a one-way driving seat fixedly mounted on the upper end of the outer wall of the transmission shaft, and an assembly groove is provided inside the one-way driving seat.

[0010] Preferably, a driving lever is rotatably mounted inside the assembly groove, and a rotating shaft is mounted at the connection between the driving lever and the one-way driving seat.

[0011] Preferably, the driving assembly further comprises a transmission rod fixedly mounted on the side wall of the vibrating rod, and two embedded balls are embedded on the wedge-shaped surface of one end of the transmission rod away from the vibrating rod.

[0012] Preferably, two symmetrically distributed vibration screen bearing assemblies are installed on both sides of the upper end of the stirring tank, and the vibration screen bearing assembly includes a bearing arc seat fixedly installed on the upper edge end surface of the stirring tank.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The vibrating assembly of the present invention makes the aggregates and cement paste in the concrete more evenly distributed through vibration, reducing the gaps and accumulation between the aggregates. This even distribution helps the aggregates to remain stable in the concrete and reduces the crushing caused by mutual squeezing. This can reduce the problem of large-particle concrete aggregate particles used in water conservancy projects being crushed due to mutual squeezing, thereby causing large-particle concrete aggregate particles to transform into small-particle aggregate particles, thereby ensuring the content of large-particle aggregates in concrete used in water conservancy projects. The coarse aggregates act as a skeleton in the concrete and can bear greater pressure, thereby improving the bearing capacity of the overall structure, thereby ensuring the density, compression resistance and impermeability of the concrete.

[0018] 2. Through the stirring action of the spiral blades, the present invention can more evenly distribute the moisture and cement paste in the concrete among the aggregates, thereby improving the fluidity of the concrete and making it easier to pump and construct; through the synergistic action of the screening vibration and the spiral blades, the cement and additives can be screened and vibrated to fall into the concrete raw materials circulating in the upper and lower layers, so that the concrete raw materials between the upper and lower layers are fully mixed; at the same time, the synergistic action of the screening vibration and the spiral blades can accelerate the mixing process of the concrete, shorten the mixing time, help improve production efficiency, and speed up the construction progress.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The present invention provides a technical solution:

[0031] See also Figures 1 to 4 and Figure 7 A concrete production device for water conservancy engineering, comprising a mixing tank 1, a raw material filling port 9 is provided at the top of the mixing tank 1, a discharge valve pipe 3 is connected to the middle position of the bottom end surface of the mixing tank 1, a servo motor 2 is fixedly installed at the top of the mixing tank 1, a transmission shaft 10 is fixedly installed at the output end of the servo motor 2, a driving component 6 is provided at the upper end of the outer wall of the transmission shaft 10, and a vibrating component 7 is provided at the power output end of the driving component 6;

[0032] The vibration component 7 includes a vibration assembly seat 701 fixedly installed on the side wall of the mixing tank 1, a vibration rod 702 is slidably installed inside the vibration assembly seat 701, two limiting grooves 705 are provided inside the vibration assembly seat 701, a connecting plate 703 and a reset spring 704 are installed inside the limiting groove 705, the upper end of the reset spring 704 is fixed on the inner upper wall of the limiting groove 705, the lower end of the reset spring 704 is fixedly connected to the upper end surface of the connecting plate 703, and the end of the connecting plate 703 away from the limiting groove 705 is fixedly connected to the side wall of the vibration rod 702.

[0033] By adopting the above technical solution, when in use, part of the concrete raw materials are added into the mixing tank 1 through the raw material filling port 9, and the servo motor 2 is started. The servo motor 2 can drive the transmission shaft 10 to rotate when it works, and the rotation of the transmission shaft 10 can drive the driving assembly 6, and the driving assembly 6 can drive the vibrating assembly 7 to work. When the vibrating rod 702 moves upward in the vibrating assembly seat 701, the vibrating rod 702 can drive the fixedly connected connecting plate 703 to move upward in the limiting groove 705. At the same time, the connecting plate 703 moving upward will compress the reset spring 704 in the limiting groove 705. When the vibrating rod 702 is unable to move upward, the vibrating rod 702 can be moved downward again under the elastic reset action of the reset spring 704, so that the concrete raw materials in the mixing tank 1 can be vibrated by the cyclic up and down movement of the vibrating rod 702. The vibrating assembly 7 makes the aggregates and cement slurry in the concrete more evenly distributed through the vibration action, and reduces the gaps and accumulation between the aggregates. This uniform distribution helps the aggregates to remain stable in the concrete and reduce the crushing caused by mutual squeezing. Vibration can also improve the density of concrete and better combine the aggregates with cement paste. The dense concrete structure can reduce the movement and mutual collision of aggregates during the force process, thereby reducing the risk of crushing. This can reduce the problem of large-particle concrete aggregate particles used in water conservancy projects being crushed due to mutual squeezing, and then causing large-particle concrete aggregate particles to transform into small-particle aggregate particles, thereby ensuring the content of large-particle aggregates in concrete used in water conservancy projects. Coarse aggregates play a skeleton role in concrete and can bear greater pressure, thereby improving the bearing capacity of the overall structure, thereby ensuring the density, compression resistance and impermeability of concrete.

[0034] Specifically, Figures 1 to 6 As shown, the driving assembly 6 includes a one-way driving seat 601 fixedly mounted on the upper end of the outer wall of the transmission shaft 10, an assembly groove 602 is opened inside the one-way driving seat 601, a driving lever 603 is rotatably mounted inside the assembly groove 602, a rotating shaft 604 is installed at the connection between the driving lever 603 and the one-way driving seat 601, and the driving assembly 6 also includes a transmission rod 605 fixedly mounted on the side wall of the vibrating rod 702, and two embedded balls 606 are embedded on the wedge-shaped surface of the end of the transmission rod 605 away from the vibrating rod 702. Two symmetrically distributed vibration screen bearing assemblies 8 are installed on both sides of the upper end of the mixing tank 1, and the vibration screen bearing assembly 8 includes a bearing arc seat 803 fixedly installed on the edge end surface of the mixing tank 1, and three spring assembly grooves 805 are opened on the upper end surface of the bearing arc seat 803. The inner bottom end of the spring assembly groove 805 is fixedly connected with a bearing spring 804, and the upper end of the bearing spring 804 is fixedly installed with a vibration screen plate 801, and a transmission bottom plate 802 corresponding to the vibrating rod 702 is fixedly installed in the middle position of the bottom end surface of the vibration screen plate 801. A spiral blade 4 is fixedly installed on the outer wall of the transmission shaft 10, and an L-shaped scraper rod 5 is fixedly installed at the bottom end of the outer wall of the transmission shaft 10.

[0035] By adopting the above technical solution, when in use, the servo motor 2 rotates forward, which can drive the transmission shaft 10 to rotate. The servo motor 2 can drive the spiral blade 4 to rotate forward through the transmission shaft 10. The forward rotation of the spiral blade 4 can transport and flip the concrete raw materials on the bottom layer of the mixing tank 1 to the upper layer inside the mixing tank 1. The rotation of the spiral blade 4 not only promotes the axial flow of the material, but also promotes the radial mixing of the material. This all-round mixing method helps to eliminate mixing dead angles and ensure that the various components of the concrete are fully contacted and mixed in the mixing tank 1; through the stirring action of the spiral blade 4, the moisture and cement slurry in the concrete can be more evenly distributed between the aggregates, improving the fluidity of the concrete, making it easier to pump and construct; in large-scale water conservancy projects, the demand for concrete is often very large, and the continuous mixing ability of the spiral blade 4 can ensure that the concrete in the mixing tank 1 always remains in a flowing state to meet the needs of continuous construction. The transmission shaft 10 can drive the fixedly connected one-way driving seat 601 to rotate forward, and the forward rotation of the one-way driving seat 601 can drive the driving lever 603 in the assembly groove 602 to rotate forward. When the driving lever 603 rotates forward, the end of the driving lever 603 close to the transmission rod 605 is provided with a wedge surface that matches the wedge surface at the end of the transmission rod 605. When the wedge surface of the driving lever 603 pushes the transmission rod 605 to move horizontally in the opposite direction, the transmission rod 605 and the vibrating rod 702 cannot move horizontally under the limitation of the vibrating assembly seat 701. Under the rolling cooperation of the embedded ball 606, the transmission rod 605 can drive the vibrating rod 702 to move upward in the vertical direction. The distance that the transmission rod 605 drives the vibrating rod 702 to move upward is greater than the distance between the top end of the vibrating rod 702 and the transmission bottom plate 802. In this way, the upward moving vibrating rod 702 can push the vibrating sieve plate 801 to move upward, and the force of the vibrating rod 702 moving upward is greater than The gravity of the vibrating sieve plate 801 and the material inside it, and the upward movement of the vibrating sieve plate 801 can drive the bearing spring 804 to stretch upward. When the vibrating rod 702 moves downward, the vibrating sieve plate 801 and the material inside it will move downward under the gravity of the vibrating sieve plate 801 and the pulling force of the bearing spring 804. In this way, through the cyclic up and down movement, the vibrating sieve plate 801 itself can vibrate, and the cement and additives in the vibrating sieve plate 801 can be vibrated and dropped into the concrete raw materials inside the mixing tank 1. When the vibrating sieve plate 801 is vibrating, the forward rotation of the spiral blade 4 can transport and flip the concrete raw materials at the bottom layer of the mixing tank 1 to the upper layer inside the mixing tank 1. In this way, through the synergistic effect of the sieving vibration and the spiral blade 4, the cement and additives can be sifted and vibrated and dropped into the circulating concrete raw materials in the upper and lower layers, so that the concrete raw materials between the upper and lower layers are fully mixed; at the same time, the synergistic effect of the sieving vibration and the spiral blade 4 can accelerate the mixing process of the concrete, shorten the mixing time, help to improve production efficiency, and speed up construction progress.After the concrete raw materials are mixed and stirred, the servo motor 2 is started, the servo motor 2 is reversed, and the discharge valve pipe 3 is opened at the same time. At this time, the servo motor 2 can drive the spiral blade 4 to reverse through the transmission shaft 10. The reverse rotation of the spiral blade 4 can transport the concrete inside the mixing tank 1 to the discharge valve pipe 3. The design of the spiral blade 4 can effectively prevent the concrete from being blocked during the transportation process. The thrust and stirring effect generated by its rotation can maintain the fluidity of the concrete and reduce the blockage problem caused by agglomeration or increased viscosity. During the transportation process, the rotation and stirring effect of the spiral blade 4 help to maintain the uniformity of the concrete. This helps to ensure the uniform distribution of various components in the concrete, such as cement, aggregates, additives, etc., and avoid performance differences caused by stratification or segregation. At the same time, the transmission shaft 10 can drive the scraper 5 to rotate when rotating, and the scraper 5 and the inner wall of the mixing tank 1 are in contact with each other, so that when rotating forward, it can play an effect of assisting the mixing of concrete raw materials. When conveying concrete in reverse, the inner wall of the mixing tank 1 can be scraped and cleaned, so that the concrete in the mixing tank 1 can be discharged more cleanly.

[0036] Working principle: When in use, part of the concrete raw materials are added into the mixing tank 1 through the raw material filling port 9, and the servo motor 2 is started. The servo motor 2 rotates forward, which can drive the transmission shaft 10 to rotate. The servo motor 2 can drive the spiral blade 4 to rotate forward through the transmission shaft 10. The forward rotation of the spiral blade 4 can transport and flip the concrete raw materials at the bottom layer of the mixing tank 1 to the upper layer inside the mixing tank 1. The rotation of the spiral blade 4 not only promotes the axial flow of the material, but also promotes the radial mixing of the material. The servo motor 2 can drive the transmission shaft 10 to rotate. The rotation of the transmission shaft 10 can drive the fixedly connected one-way drive seat 601 to rotate forward. The forward rotation of the one-way drive seat 601 can drive the drive lever 603 in the assembly slot 602 to rotate forward. The drive lever 603 rotates forward. When rotating, the end of the driving lever 603 close to the transmission rod 605 is provided with a wedge-shaped surface that matches the wedge-shaped surface at the end of the transmission rod 605. When the wedge-shaped surface of the driving lever 603 pushes the transmission rod 605 to move horizontally in the opposite direction, the transmission rod 605 and the vibrating rod 702 cannot move in the horizontal direction under the limitation of the vibrating assembly seat 701. Under the rolling cooperation of the embedded ball 606, the transmission rod 605 can drive the vibrating rod 702 to move upward in the vertical direction. When the vibrating rod 702 moves upward in the vibrating assembly seat 701, the vibrating rod 702 can drive the fixedly connected connecting plate 703 to move upward in the limiting groove 705. At the same time, the upwardly moving connecting plate 703 will compress the return spring 704 in the limiting groove 705. When the vibrating rod 7 02 is unable to move upward, under the elastic restoring action of the restoring spring 704, the vibrating rod 702 can be moved downward again, so that the concrete raw materials in the mixing tank 1 can be vibrated through the cyclic up and down movement of the vibrating rod 702, and the transmission rod 605 drives the vibrating rod 702 to move upward The distance is greater than the distance between the top of the vibrating rod 702 and the transmission bottom plate 802, so that the upward moving vibrating rod 702 can push the vibrating sieve plate 801 to move upward, and the upward moving force of the vibrating rod 702 is greater than the gravity of the vibrating sieve plate 801 and the material inside it. The upward movement of the vibrating sieve plate 801 can drive the load-bearing spring 804 to stretch upward. When the vibrating rod 702 moves downward, the gravity of the vibrating sieve plate 801 and the material inside it and the load-bearing spring 804 The sieve plate 801 itself can vibrate by moving up and down in a cycle, and the cement and additives in the sieve plate 801 can be vibrated and dropped into the concrete raw materials inside the mixing tank 1. When the sieve plate 801 is vibrating, the spiral blade 4 can rotate forward to transport the concrete raw materials at the bottom of the mixing tank 1 to the upper layer inside the mixing tank 1. In this way, the cement and additives can be vibrated and dropped into the concrete raw materials circulating in the upper and lower layers through the synergistic effect of the sieve vibration and the spiral blade 4, so that the concrete raw materials between the upper and lower layers are fully mixed. When the concrete raw materials are mixed and stirred, the servo motor 2 is started, the servo motor 2 is reversed, and the discharge valve pipe 3 is opened at the same time. At this time, the servo motor 2 can drive the spiral blade 4 to reverse through the transmission shaft 10.The reverse rotation of the spiral blade 4 can transport the concrete inside the mixing tank 1 to the discharge valve pipe 3, so that the concrete can be discharged from the discharge valve pipe 3. At the same time, the transmission shaft 10 can drive the scraper rod 5 to rotate when rotating. The scraper rod 5 fits with the inner wall of the mixing tank 1, so that it can assist in the mixing of concrete raw materials when rotating forward. When transporting concrete in the reverse rotation, the inner wall of the mixing tank 1 can be scraped and cleaned, so that the concrete in the mixing tank 1 can be discharged more cleanly. When the transmission shaft 10 rotates in the reverse direction, it can drive the fixedly connected one-way drive The seat 601 rotates in the opposite direction. The one-way drive seat 601 rotates in the opposite direction to drive the driving lever 603 in the assembly groove 602 to rotate in the opposite direction. At this time, the vertical back of the driving lever 603 rotating in the opposite direction will abut against the vertical back of the transmission rod 605. By squeezing and pushing, the driving lever 603 can be rotated in the assembly groove 602 through the rotating shaft 604, so that the driving lever 603 and the transmission rod 605 that are abutting and squeezing each other can be separated. In this way, it can be prevented that the driving assembly 6 drives the vibrating assembly 7 to operate when the transmission shaft 10 rotates in the opposite direction.
