Description

Technical Field

[0001] This application relates to the technical field of building construction, and particularly to a concrete pouring device for building construction. Background Art

[0002] With the rapid development of the country and the continuous progress of society, the urbanization process in China is accelerating, and various infrastructure facilities are being continuously improved. Concrete is an essential material for infrastructure construction. During the concrete pouring process, due to the frictional resistance between the aggregates of concrete and the adhesive force of the cement slurry, it cannot fill and compact itself. Its interior is loose, with cavities and bubbles of a certain volume, and it cannot reach the required density, thus affecting its strength, frost resistance, impermeability, and durability, and vibration treatment is required.

[0003] A concrete vibrator is a machine for mechanically compacting concrete. During operation, construction workers hold a flexible hose and insert the vibrating rod of the device into the concrete. After turning on the drive mechanism, the drive mechanism drives the eccentric rotor inside the vibrating rod to rotate, thereby generating periodic vibrations, and transmitting the vibrations to the concrete through the housing of the vibrating rod, causing the bubbles in the concrete to float under the action of vibration, so as to be able to remove the bubbles in the concrete, make the concrete compactly combined, eliminate phenomena such as honeycombing and pitting on the concrete surface, thereby improving the strength of the concrete and ensuring the quality of concrete components.

[0004] However, there are still some problems in the use of existing concrete pouring equipment: First, when the vibrating rod is inserted into the concrete, the concrete fluid will adhere to the surface of the vibrating rod. When the vibrating rod is working, the eccentric rotor rotates and continuously generates and accumulates heat. Therefore, after the vibrating rod is pulled out, if it is not cleaned in time, the concrete fluid adhering to the surface of the vibrating rod will be heated and condensed on the surface of the vibrating rod, increasing the labor intensity of later cleaning by workers; Second, after vibration, pits are likely to appear at the position where the vibrating rod is pulled out, affecting the later leveling of the concrete. Summary of the Invention

[0005] This application proposes a concrete pouring device for building construction, which has the advantages of timely and sufficient cleaning of the concrete fluid adhering to the surface of the vibrating rod and the fixing component, reducing the later cleaning difficulty and improving the later leveling effect, so as to solve the problem that after the vibrating rod is pulled out, the concrete fluid is heated and condensed on the surface of the vibrating rod due to untimely cleaning, increasing the labor intensity of later cleaning by workers, and solving the problem that after vibration, pits are likely to appear at the position where the vibrating rod is pulled out, affecting the later leveling of the concrete.

[0006] To achieve the above object, this application adopts the following technical solution: A concrete pouring device for building construction, comprising: A vibrating rod, the vibrating rod includes a vibrating housing; Fixing component, a fixing component is fixedly sleeved on the outer wall of the vibrating housing; Moving component, a moving component is movably clamped on the fixing component, and the inner ring of the moving component is movably sleeved on the outer wall of the vibrating housing; When the vibrating rod is pulled out of the concrete, the moving component will move downward relative to the vibrating rod and the fixing component, timely and fully cleaning the concrete fluid attached to the surfaces of the vibrating rod and the fixing component, and replenishing the concrete at the pulling-out positions of the vibrating rod and the fixing component.

[0007] Furthermore, the vibrating rod, the fixing component and the moving component form a vibration mechanism.

[0008] Furthermore, the vibrating rod further includes: Bearing, the upper end inside the vibrating housing is fixedly connected to the outer ring of the bearing; Eccentric rotor, the inner ring of the bearing is fixedly connected to the upper end of the eccentric rotor.

[0009] Furthermore, the eccentric rotor includes: Rotating shaft, the rotating shaft is concentric with the vibrating housing, and the bottom end of the rotating shaft abuts against the bottom end inside the vibrating housing; Counterweight plate, one side of the outer wall of the rotating shaft is fixedly connected with a counterweight plate, and the counterweight plate is located below the bearing; Counterweight block, a vertical groove is formed in the middle of the counterweight plate, and the counterweight plate is fixedly connected with the counterweight block through the vertical groove. The counterweight block is a through electromagnet, and whether the counterweight block is energized is related to whether the rotating shaft rotates. When energized, one end of the counterweight block close to the inner wall of the vibrating housing has an S-shaped magnetism, and the end of the counterweight block far from the inner wall of the vibrating housing has an N-shaped magnetism.

[0010] Furthermore, a plurality of transverse holes are formed in the counterweight plate, and the transverse holes are arranged in a vertical array. The shape of the transverse holes is S-shaped, and when the eccentric rotor rotates, the port of the transverse hole facing away from the inner wall of the vibrating housing is the air flow incoming port, and the port of the transverse hole facing the inner wall of the vibrating housing is the air flow outgoing port.

[0011] By forming S-shaped transverse holes in the counterweight plate, when the eccentric rotor rotates at a high speed, the air flow will pass through the S-shaped transverse holes, not only effectively dissipating heat from the eccentric rotor to fully cool the eccentric rotor in cooperation with the cooling system, but also enabling the outgoing air flow to impact the inner wall of the vibrating housing, further enhancing the vibration effect of the vibrating housing and improving the vibrating efficiency of the concrete.

[0012] Furthermore, the fixing component includes: Fixing rings, the number of the fixing rings is two, and one fixing ring is threadedly sleeved on the outer wall of the upper half of the vibrating housing, and the other fixing ring is threadedly sleeved on the outer wall of the lower half of the vibrating housing; Fixed rod, a fixed rod is fixedly connected between the two fixing rings. The number of the fixed rods is several, and several fixed rods are uniformly arranged around the vibrating housing. A fixing cavity is formed inside the fixed rod; Sealing ball, several fixing holes are formed on one side of the fixing ring away from the vibrating housing. The several fixing holes are arranged in a vertical array, and the fixing holes communicate with the fixing cavity. The fixing holes are composed of a frustum-shaped hole and a cylindrical hole. A sealing ball is arranged in the frustum-shaped hole. One outer wall of the sealing ball is adapted to the opening end of the frustum-shaped hole. A fixing spring is arranged between the other outer wall of the sealing ball and the inner wall of the frustum-shaped hole. A waterproof and breathable film is fixedly sleeved in the cylindrical hole.

[0013] Further, the movable assembly includes: Movable plate, the inner circle of the movable plate is movably sleeved on the vibrating housing surrounded by the fixed rods, and the moving range of the movable plate is the distance between the two fixing rings. Several micro air holes are vertically formed on the movable plate; Movable film, a movable groove is formed on the outer circle of the movable plate. One end of the movable film is fixedly sleeved on one side of the movable groove close to the vibrating housing, and the other end of the movable film is movably sleeved on one side of the movable groove away from the vibrating housing. The movable films correspond to the fixed rods one by one; Movable block, a movable block is fixedly connected to the inner wall surface of the movable film away from the fixed rod, and the movable block is connected to the movable plate through a return spring. The movable block is a permanent magnet, and one side of the movable block close to the vibrating housing has an S-shaped magnetism, and the side of the movable block away from the vibrating housing has an N-shaped magnetism; Air inlet member, one end of the air inlet member passes through the movable plate and is fixedly communicated with the inside of the movable film, and the other end of the air inlet member is fixedly communicated with the top end inside the fixed rod; Air outlet member, one end of the air outlet member passes through the movable plate and is fixedly communicated with the inside of the movable film, and the other end of the air outlet member communicates with the outside. A one-way air valve is arranged inside the air outlet member; Cleaning strip, a cleaning strip is fixedly connected to the bottom end of the movable film below the movable block. The cleaning strip is arc-shaped and fits the bottom surface of the movable plate. Adjacent two cleaning strips are stagger-designed.

[0014] By setting the movable assembly, and the movable assembly is composed of a movable plate, a movable film, a movable block, an air inlet member, an air outlet member and a cleaning strip. When the eccentric rotor changes from working to non-working, the movable film contracts under the pulling force of the return spring and drives the cleaning strip to move inwards, so as to effectively clean the concrete attached to the bottom surface of the movable assembly, further prevent the concrete from condensing on the surface of the vibrating rod, and effectively reduce the labor intensity of the later-stage staff cleaning.

[0015] By setting a fixed component, which consists of a fixed ring, a fixed rod and a sealing ball, and at the same time setting an eccentric rotor, which consists of a rotating shaft, a counterweight plate and counterweight blocks. When the eccentric rotor works, since several movable blocks are arranged around the counterweight blocks, the movable blocks will approach the counterweight blocks one by one. Also, due to the magnetic repulsive force between the movable blocks and the counterweight blocks, the movable blocks will expand. Moreover, because the eccentric rotor rotates at a high speed and the return spring has mechanical inertia, the movable membrane is always in an expanded state under the action of the magnetic repulsive force. Additionally, since the fixed cavity of the fixed rod is connected to the movable groove of the movable membrane through an air inlet component, when the movable membrane expands, a negative pressure environment will be generated inside the fixed rod, effectively enhancing the effect of the fixed component in absorbing the gas in the concrete, thereby improving the effect of removing bubbles in the concrete. When the eccentric rotor does not work, the movable membrane shrinks and the excess gas inside the movable membrane is discharged in time through an air outlet component, so as to improve the working effect of the movable component and the fixed component on the concrete next time.

The transmission part is a flexible core shaft tightly wound by multiple layers of steel wires; A hose housing, the outside of the transmission part is wrapped with a hose housing, and grease is filled between the hose housing and the transmission part.

[0018] The beneficial effects of the present invention are as follows: A concrete pouring device for building construction provided by the present application, by fixedly sleeving a fixed component on the outside of the vibrating rod and movably sleeving a movable component on the outside of the vibrating rod and the fixed component. When the vibrating rod is inserted into the concrete, the movable component is above the top surface of the concrete under the action of the surface buoyancy of the concrete. When the vibrating rod is pulled out of the concrete, the vibrating rod and the fixed component move upward while the movable component remains stationary. Thus, the movable component moves downward relative to the vibrating rod and the fixed component, which can not only effectively and timely clean the concrete fluid attached to the surfaces of the vibrating rod and the fixed component, prevent the concrete from coagulating on the surface of the vibrating rod, effectively reducing the labor intensity of the later staff for cleaning, but also supplement the concrete at the pulling-out position of the vibrating mechanism, effectively reducing the difficulty of the later staff in leveling the concrete.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1, a concrete pouring device for building construction, including a driving mechanism 1, such as Figure 1 , the types of the driving mechanism 1 include motors, engines, etc., which are used to provide a power source to drive the rotation of the hose housing 21 in the transmission mechanism 2 and the eccentric rotor 7 in the vibration rod 4. The driving mechanism 1 is placed in the working frame to facilitate the handling of the driving mechanism 1.

[0023] Such as Figures 1 - 3 , one end of the transmission mechanism 2 is connected to the driving mechanism 1, and the other end of the transmission mechanism 2 is connected to the vibration rod 4, which is used to connect the driving mechanism 1 and the vibration rod 4. The transmission mechanism 2 is flexible, which is convenient for the operator to move flexibly and insert the vibration rod 4. The transmission mechanism 2 includes a hose housing 21 and a transmission part 22, such as Figure 3 And Figure 10 , the output shaft of the driving mechanism 1 is connected to one end of the transmission part 22 through a connector (such as a coupling or a chuck). The other end of the transmission part 22 passes through the vibration housing 41 and is connected to the top end of the rotating shaft 71. The transmission part 22 is a flexible core shaft tightly wound by multiple layers of steel wires. The core shaft has excellent torsional stiffness (able to transmit torque) and flexibility (able to bend). When the driving mechanism 1 rotates, its torque is directly transmitted to the transmission part 22 inside the hose housing 21, causing the transmission part 22 to rotate at a high speed, and then driving the eccentric rotor 7 to rotate at a high speed together. The outside of the transmission part 22 is wrapped with a hose housing 21. The hose housing 21 is made of rubber or plastic, and grease is filled between the hose housing 21 and the transmission part 22. The design of the hose housing 21 can protect the transmission part 22, prevent concrete, mortar, water or other sundries from invading and damaging the transmission part 22, can also reduce the frictional resistance when the transmission part 22 rotates, help with heat dissipation and prevent rust, and can prevent the operator from contacting the transmission part 22 rotating at a high speed.

[0024] As shown in Figures 2 - 3 , the vibrating rod 4 includes a vibrating housing 41, a bearing 42 and an eccentric rotor 7. As shown in Figures 9 - 12 , the bottom end of the vibrating housing 41 is a smooth hemisphere, which is convenient for inserting into the concrete. The vibrating housing 41 is usually made of wear-resistant and impact-resistant steel, effectively protecting its internal components. The upper end inside the vibrating housing 41 is fixedly connected to the outer ring of the bearing 42, and the inner ring of the bearing 42 is fixedly connected to the upper end of the eccentric rotor 7. The bearing 42 is used to effectively and stably set the eccentric rotor 7 inside the vibrating housing 41, thereby supporting the high-speed rotation of the eccentric rotor 7. The vibrating housing 41 vibrates under the action of the centrifugal force of the eccentric rotor 7, making the concrete inserted by the vibrating rod 4 more compact and firm. It should be noted that a cooling system is provided inside the vibrating housing 41, which can introduce cold air according to the temperature inside the vibrating housing 41 to reduce its internal temperature and prevent the vibrating rod 4 from being damaged due to overheating.

[0025] As shown in Figures 7 - 8 、 Figure 13 , a fixing component 5 is fixedly sleeved on the outer wall of the vibrating housing 41, which can guide the gas in the concrete to be fully discharged.

[0026] As shown in Figures 2 - 6 、 Figures 14 - 15 , a movable component 6 is movably clamped on the fixing component 5, and the inner ring of the movable component 6 is movably sleeved on the outer wall of the vibrating housing 41, which can clean the concrete fluid adhered to the vibrating rod 4 and the fixing component 5.

[0027] As shown in Figures 1 - 2 , in summary, the vibrating rod 4, the fixing component 5 and the movable component 6 constitute a vibrating mechanism 3, which is used to vibrate the concrete to eliminate the air bubbles in the concrete, make the concrete densely combined, thereby eliminating phenomena such as honeycombing and pitting on the concrete surface, improving the strength of the concrete, and ensuring the quality of concrete components.

[0028] When the vibrating rod 4 is pulled out of the concrete, the movable component 6 will move downward relative to the vibrating rod 4 and the fixing component 5. It can not only clean the concrete fluid attached to the surface of the vibrating rod 4 and the fixing component 5 in a timely and sufficient manner, prevent the concrete from coagulating on the surface of the vibrating rod, effectively reducing the labor intensity of the later staff for cleaning, but also supplement the concrete at the position where the vibrating rod 4 is pulled out, effectively reducing the difficulty of later staff for leveling the concrete.

[0029] Embodiment 2: On the basis of Embodiment 1, the eccentric rotor 7 includes a rotating shaft 71, a counterweight plate 72 and a counterweight block 73. As shown in Figures 10 - 12, the rotating shaft 71 and the vibrating housing 41 are concentrically arranged, and the bottom end of the rotating shaft 71 abuts against the inner bottom end of the vibrating housing 41, effectively ensuring the stability of the rotating shaft 71 working in the vibrating housing 41. One side of the outer wall of the rotating shaft 71 is fixedly connected with a counterweight plate 72, and the counterweight plate 72 is located below the bearing 42. A vertical groove is formed in the middle of the counterweight plate 72, and the counterweight plate 72 is fixedly connected with a counterweight block 73 through the vertical groove. By using the shape design of the rotating shaft 71, the counterweight plate 72 and the counterweight block 73, the eccentric rotor 7 is effectively made into a component with uneven mass distribution (eccentric). When this component rotates at a high speed, it generates a centrifugal force whose direction changes rapidly. This centrifugal force drives the vibrating rod 4 to generate high-frequency and small-amplitude circular vibration or elliptical vibration along its radial direction.

[0030] As Figure 12 , a plurality of transverse holes are formed in the counterweight plate 72, and the transverse holes are arranged in a vertical array. The shape of the transverse holes is S-shaped. When the eccentric rotor 7 rotates, the port of the transverse hole facing away from the inner wall of the vibrating housing 41 is the air flow incoming port, and the port of the transverse hole facing the inner wall of the vibrating housing 41 is the air flow outgoing port. When the eccentric rotor 7 rotates at a high speed, the air flow will pass through the transverse holes, not only dissipating heat from the eccentric rotor 7 to cooperate with the cooling system to fully cool the eccentric rotor 7, but also enabling the outgoing air flow to impact the inner wall of the vibrating housing 41, further enhancing the vibration effect of the vibrating housing 41 and improving the vibrating efficiency of the concrete.

[0031] Embodiment 3, on the basis of Embodiment 2, the fixing assembly 5 includes a fixing ring 51, a fixing rod 52 and a sealing ball 53, as Figures 7 - 8 , Figure 13 , the number of the fixing rings 51 is two. One fixing ring 51 is threadedly sleeved on the outer wall of the upper half of the vibrating housing 41, and the other fixing ring 51 is threadedly sleeved on the outer wall of the lower half of the vibrating housing 41, which is convenient for disassembling and replacing the fixing assembly 5. A fixing rod 52 is fixedly connected between the two fixing rings 51. The number of the fixing rods 52 is several, and several fixing rods 52 are uniformly arranged around the vibrating housing 41. A fixing cavity is formed inside the fixing rod 52, which helps to fully discharge the gas in the concrete around the vibrating housing 41. A plurality of fixing holes are formed on one side of the fixing ring 51 far from the vibrating housing 41. The plurality of fixing holes are arranged in a vertical array, and the fixing holes are communicated with the fixing cavity, so that the external gas can be absorbed into the fixing holes and then enter the fixing cavity, as Figures 3 - 5, the fixing hole is composed of a frustum-shaped hole and a cylindrical hole, and the cylindrical hole is arranged between the fixing cavity and the frustum-shaped hole. A sealing ball 53 is arranged in the frustum-shaped hole. The outer wall of one side of the sealing ball 53 is adapted to the open end of the frustum-shaped hole. That is, when the vibrating work is not carried out, the sealing ball 53 can effectively seal the frustum-shaped hole of the fixing ring 51. A fixing spring is arranged between the outer wall of the other side of the sealing ball 53 and the inner wall of the frustum-shaped hole. That is, when the vibrating work is carried out, due to the magnetic repulsive force generated by the eccentric rotor 7 on the movable component 6, the air pressure in the fixing cavity of the fixing rod 52 decreases, thereby generating an air pressure difference pointing from the outside of the fixing ring 51 to the inside of the fixing ring 51. Under the action of this air pressure difference, the sealing ball 53 will move towards the fixing cavity direction, so that a very small gap is generated between the outer wall of the sealing ball 53 and the open end of the frustum-shaped hole, so that the gas in the concrete can enter the fixing ring 51 under the action of this negative pressure, and because the formed gap is small, large particle building materials such as concrete cannot enter, so that the air bubbles in the concrete can be better eliminated and the compactness of the concrete can be improved. A waterproof and breathable membrane is fixedly sleeved in the cylindrical hole, so that the water in the concrete can be blocked outside the fixing cavity of the fixing rod 52, and the gas in the concrete can pass through to prevent the water from affecting the negative pressure environment in the fixing rod 52.

[0032] Embodiment 4, on the basis of Embodiment 3, as Figures 11 - 12 , the counterweight 73 is a through electromagnet, and whether the counterweight 73 is energized is associated with whether the rotating shaft 71 rotates. When the rotating shaft 71 rotates, the counterweight 73 is energized. When the rotating shaft 71 does not rotate, the counterweight 73 is de-energized. As Figure 3 、 Figure 6 , when energized, one end of the counterweight 73 close to the inner wall of the vibrating housing 41 has an S-shaped magnetism, and the end of the counterweight 73 far from the inner wall of the vibrating housing 41 has an N-shaped magnetism. The magnetic pole direction design of the counterweight 73 is used to magnetically control the movable component 6 so as to better eliminate air bubbles during work.

[0033] As Figure 2 、 Figures 14 - 15 , the movable component 6 includes a movable plate 61, a movable membrane 62, a movable block 63, an air inlet member 64, an air outlet member 65 and a cleaning strip 66. As Figures 5 - 6, the inner ring of the movable plate 61 is movably sleeved with the vibrating housing 41 surrounding the fixed rod 52, and the moving range of the movable plate 61 is the distance between the two fixed rings 51, so as to effectively clean the concrete adhered to the vibrating rod 4 and the fixing assembly 5. A number of tiny air holes are vertically formed on the movable plate 61, which can not only reduce the mass of the movable plate 61, making the movable plate 61 always float on the surface of the concrete, but also not prevent the effective discharge of the gas in the concrete. An activity groove is formed on the outer ring of the movable plate 61. The movable membrane 62 is press-fitted and sleeved in the activity groove of the movable plate 61, and one end of the movable membrane 62 is fixedly sleeved with one side of the activity groove close to the vibrating housing 41, and the other end of the movable membrane 62 is movably sleeved with one side of the activity groove far from the vibrating housing 41. The movable membranes 62 correspond to the fixed rods 52 one by one. By using the deformation generated by the transformation of the movable membrane 62 between the contracted state and the extended state, the concrete fluid adhered to the bottom end of the movable membrane 62 is vibrated and cleaned. An activity block 63 is fixedly connected to the inner wall surface of the movable membrane 62 far from the fixed rod 52, and the activity block 63 is connected to the movable plate 61 through a return spring. When the eccentric rotor 7 does not work, under the pulling force of the return spring, the activity block 63 is pulled to move towards the vibrating housing 41, thereby realizing the contraction of the movable membrane 62. The activity block 63 is a permanent magnet, and one side of the activity block 63 close to the vibrating housing 41 has an S-shaped magnetism, and the side of the activity block 63 far from the vibrating housing 41 has an N-shaped magnetism. When the eccentric rotor 7 works, since a number of activity blocks 63 are arranged around the counterweight 73, the counterweight 73 will approach each activity block 63 one by one, so that the counterweight 73 will generate a magnetic repulsive force on each activity block 63, thereby realizing the unfolding of the movable membrane 62. Also, because the counterweight 73 rotates at a high speed, the return spring cannot contract in time due to mechanical inertia, so that the activity block 63 is always in the unfolded state, as Figures 4 - 5, one end of the air inlet member 64 passes through the movable plate 61 and is fixedly connected to the inside of the movable membrane 62, and the other end of the air inlet member 64 is fixedly connected to the inner top end of the fixed rod 52. By using the air inlet member 64, the inside of the movable membrane 62 is communicated with the inside of the fixed rod 52, so that the air pressure in the movable membrane 62 affects the air pressure in the fixed rod 52. When the movable membrane 62 extends, its volume increases and the air pressure decreases, effectively causing the air pressure in the fixed rod 52 to decrease. That is, when the movable membrane 62 unfolds, a negative pressure environment will be generated in the fixed rod 52, effectively enhancing the effect of the fixed assembly 5 in absorbing the gas in the concrete, thereby improving the efficiency of removing bubbles in the concrete. One end of the air outlet member 65 passes through the movable plate 61 and is fixedly connected to the inside of the movable membrane 62, and the other end of the air outlet member 65 is communicated with the outside. A one-way air valve is provided in the air outlet member 65. If the air pressure in the movable membrane 62 increases and reaches the critical value, the one-way air valve of the air outlet member 65 will be opened. In particular, when the movable membrane 62 contracts, its volume decreases and the air pressure increases, effectively discharging the excess gas to improve the effect of removing bubbles in the concrete next time. A cleaning strip 66 is fixedly connected to the bottom end of the movable membrane 62 below the movable block 63. The cleaning strip 66 is arc-shaped and fits the bottom surface of the movable plate 61. Adjacent two cleaning strips 66 are stagger-designed. When the movable membrane 62 drives the cleaning strip 66 to move, the concrete fluid adhered to the bottom end of the movable plate 61 can be effectively cleaned.

[0034] The working principle of the usage method of the present invention is as follows: First, the staff holds the transmission mechanism 2 to insert the vibrating rod 4 into the concrete, and the fixed assembly 5 enters synchronously with the vibrating rod 4. During this process, the movable assembly 6 is above the top surface of the concrete due to the buoyancy of the concrete surface. After that, the eccentric rotor 7 is driven by the driving mechanism 1 to rotate at a high speed to drive the vibrating housing 41 to vibrate, thereby vibrating the concrete. After that, the staff pulls out the vibrating rod 4, and the fixed assembly 5 is pulled out synchronously with the vibrating rod 4. During this process, the movable assembly 6 still floats above the top surface of the concrete, so that the movable assembly 6 moves downward relative to the vibrating rod 4 and the fixed assembly 5, effectively and timely cleaning the concrete fluid attached to the surfaces of the vibrating rod 4 and the fixed assembly 5. It can not only prevent the concrete from condensing on the surface of the vibrating rod, effectively reducing the labor intensity of the staff's later cleaning, but also supplement the concrete at the pulling-out position of the vibrating mechanism 3, effectively reducing the difficulty of the staff's later leveling of the concrete.

[0035] During the high-speed rotation of the eccentric rotor 7, since the S-shaped transverse hole is provided on the counterweight plate 72, at this time, the air flow will pass through the S-shaped transverse hole, not only effectively dissipating heat from the eccentric rotor 7 to cooperate with the cooling system to fully and quickly cool down the eccentric rotor 7, but also enabling the air flow in the going direction to impact the inner wall of the vibrating housing 41, further enhancing the vibration effect of the vibrating housing 41 and improving the vibrating efficiency of the concrete.

[0036] During the high-speed rotation of the eccentric rotor 7, the rotating shaft 71 and the counterweight block 73 are linked together, so that the counterweight block 73 is energized and has magnetism, so that the counterweight block 73 can generate a magnetic repulsive force on the movable block 63, so that the movable block 63 pushes the movable membrane 62 to stretch. Since the return spring has mechanical inertia, the return spring cannot respond in time and the movable membrane 62 is always in the expanded state. At this time, the fixed cavity of the fixed rod 52 is connected with the movable groove of the movable membrane 62 through the air inlet member 64, so that the air pressure in the movable membrane 62 affects the air pressure in the fixed rod 52. The extension of the movable membrane 62 increases its volume and reduces the air pressure, which effectively reduces the air pressure in the fixed rod 52, thereby generating a negative pressure environment in the fixed rod 52. , that is, an air pressure difference is generated from the outside of the fixing ring 51 to the inside of the fixing ring 51. Under the action of the air pressure difference, the sealing ball 53 will move toward the fixed cavity, so that a very small gap is generated between the outer wall of the sealing ball 53 and the open end of the frustum hole of the fixing rod 52, so that large particles of building materials such as concrete cannot enter. Then, due to the design of the waterproof and breathable membrane in the cylindrical hole, water in the concrete cannot enter, so that only the gas in the concrete can enter the fixed cavity of the fixing ring 51 under the action of the negative pressure until it is discharged into the movable groove of the movable membrane 62, thereby better eliminating bubbles in the concrete, improving the density of the concrete, and then cooperating with the vibration of the vibrating rod 4 to improve the overall vibration efficiency of the vibration mechanism 3.

[0037] When the eccentric rotor 7 is no longer rotating at high speed, the counterweight block 73 is powered off and does not generate magnetic repulsion on the movable block 63, so that the reset spring pulls the movable membrane 62 to contract, thereby vibrating and cleaning the concrete adhered to the bottom end of the movable membrane 62, and at the same time drives the cleaning strip 66 to move inward synchronously to scrape and clean the concrete adhered to the bottom end of the movable plate 61. In summary, the concrete adhered to the bottom surface of the movable component 6 is effectively cleaned, further preventing the concrete from solidifying on the surface of the vibrating rod, and effectively reducing the labor intensity of the subsequent cleaning staff.
