Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a concrete pouring device used in building construction. Background Art

[0002] With the rapid development of the country and the continuous progress of society, my country's urbanization process is accelerating, and various infrastructures are constantly being improved. Concrete is an indispensable material for infrastructure construction. During the concrete pouring process, due to the friction between the aggregates and the cohesive force of the cement paste, the concrete cannot fill and compact on its own. The concrete is loose and has a certain amount of voids and bubbles. It cannot achieve the required density, thus affecting its strength, frost resistance, impermeability, and durability. Therefore, it needs to be vibrated.

[0003] A concrete vibrator is a mechanized tool for compacting concrete. During operation, the construction worker holds a hose and inserts the vibrating rod of the equipment into the concrete. The driving mechanism will drive the eccentric rotor in the vibrating rod to rotate, thereby generating periodic vibrations. The vibrations are transmitted to the concrete through the shell of the vibrating rod, causing the bubbles in the concrete to float up under the action of the vibration, thereby eliminating the bubbles in the concrete, making the concrete densely combined, and eliminating the honeycombed surface of the concrete, thereby improving the strength of the concrete and ensuring the quality of the concrete components.

[0004] However, there are still some problems with the existing concrete pouring equipment during use: 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 the subsequent cleaning staff; secondly, after vibration, potholes are likely to appear at the position where the vibrating rod is pulled out, affecting the subsequent leveling of the concrete. Summary of the Invention

[0005] The present application proposes a concrete pouring equipment for construction, which has the advantages of timely and sufficient cleaning of concrete fluid adhered to the surface of the vibrating rod and the fixed component, which not only reduces the difficulty of cleaning in the later stage, but also improves the leveling effect in the later stage. It is used 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, thereby increasing the labor intensity of the later cleaning staff, and solves the problem that after vibration, the position where the vibrating rod is pulled out is prone to potholes, which affects the leveling of the concrete in the later stage.

[0006] To achieve the above objectives, the present application adopts the following technical solution: a concrete pouring device for building construction, comprising:

[0007] A vibrating rod, comprising a vibrating shell;

[0008] A fixing component, wherein the outer wall of the vibration shell is fixedly sleeved with the fixing component;

[0009] A movable component is movably connected to the fixed component, and the inner ring of the movable component is movably sleeved with the outer wall of the vibration shell;

[0010] When the vibrating rod is pulled out of the concrete, the movable component will move downward relative to the vibrating rod and the fixed component, promptly and fully cleaning the concrete fluid attached to the surface of the vibrating rod and the fixed component, and replenishing concrete at the pull-out position of the vibrating rod and the fixed component.

[0011] Furthermore, the vibration rod, the fixed component and the movable component constitute a vibration mechanism.

[0012] Furthermore, the vibrating rod further comprises:

[0013] A bearing, wherein the inner upper end of the vibration shell is fixedly connected to the outer ring of the bearing;

[0014] The eccentric rotor has an inner ring of the bearing fixedly connected to the upper end of the eccentric rotor.

[0015] Furthermore, the eccentric rotor includes:

[0016] A rotating shaft, wherein the rotating shaft and the vibration shell are concentrically arranged, and the bottom end of the rotating shaft abuts against the inner bottom end of the vibration shell;

[0017] A counterweight plate is fixedly connected to one side of the outer wall of the rotating shaft, and the counterweight plate is located below the bearing;

[0018] The counterweight block has a vertical slot in the middle of the counterweight plate, and the counterweight plate is fixedly connected to the counterweight block through the vertical slot. The counterweight block is an electromagnet, and whether the counterweight block is energized is related to whether the rotating shaft rotates. When energized, the end of the counterweight block close to the inner wall of the vibration shell has S-type magnetism, and the end of the counterweight block away from the inner wall of the vibration shell has N-type magnetism.

[0019] Furthermore, a plurality of transverse holes are provided on 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 vibration shell is the airflow inlet, and the port of the transverse hole facing the inner wall of the vibration shell is the airflow outlet.

[0020] By opening an S-shaped horizontal hole on the counterweight plate, when the eccentric rotor rotates at high speed, the air flow will pass through the S-shaped horizontal hole, which not only effectively dissipates the heat of the eccentric rotor to cooperate with the cooling system to achieve sufficient cooling of the eccentric rotor, but also enables the outgoing air flow to impact the inner wall of the vibration shell, further enhancing the vibration effect of the vibration shell and improving the vibration efficiency of the concrete.

[0021] Furthermore, the fixing assembly includes:

[0022] Two fixing rings are provided, one of which is threadedly sleeved on the upper outer wall of the vibration shell, and the other is threadedly sleeved on the lower outer wall of the vibration shell;

[0023] A fixing rod, wherein the two fixing rings are fixedly connected with a fixing rod, the fixing rods are multiple in number, and the multiple fixing rods are evenly arranged around the vibration shell, and a fixing cavity is opened inside the fixing rod;

[0024] A sealing ball is provided with a plurality of fixing holes on the side of the fixing ring away from the vibration shell. The plurality of fixing holes are arranged in a vertical array and are connected to the fixing cavity. The fixing holes are composed of a conical hole and a cylindrical hole. A sealing ball is provided in the conical hole. One side outer wall of the sealing ball is adapted to the open end of the conical hole. A fixing spring is provided between the other side outer wall of the sealing ball and the inner wall of the conical hole. A waterproof and breathable membrane is fixedly sleeved in the cylindrical hole.

[0025] Furthermore, the active components include:

[0026] A movable plate, the inner ring of which is movably connected to the vibration shell surrounded by the fixed rod, and the movable plate has a range of movement equal to the distance between the two fixed rings, and a plurality of tiny air holes are vertically opened on the movable plate;

[0027] A movable membrane, wherein the outer ring of the movable plate is provided with a movable groove, and one end of the movable membrane is fixedly sleeved with a side of the movable groove close to the vibration shell, and the other end of the movable membrane is movably sleeved with a side of the movable groove away from the vibration shell, and the movable membrane corresponds to the fixed rod one by one;

[0028] A movable block is fixedly connected to the inner wall of the movable membrane away from the fixed rod, and the movable block is connected to the movable plate via a return spring. The movable block is a permanent magnet, and the side of the movable block close to the vibration shell has S-type magnetism, and the side of the movable block away from the vibration shell has N-type magnetism;

[0029] an air inlet member, one end of which passes through the movable plate and is fixedly connected to the interior of the movable membrane, and the other end of which is fixedly connected to the inner top end of the fixed rod;

[0030] an air outlet member, one end of which passes through the movable plate and is fixedly connected to the interior of the movable membrane, the other end of which is connected to the outside, and a one-way air valve is provided in the air outlet member;

[0031] A cleaning strip is fixedly connected to the bottom end of the movable membrane below the movable block. The cleaning strip is arc-shaped and fits the bottom surface of the movable plate. Two adjacent cleaning strips are staggered.

[0032] By setting up a movable component, which consists of a movable plate, a movable membrane, a movable block, an air inlet piece, an air outlet piece and a cleaning strip, when the eccentric rotor changes from working to non-working, the movable membrane contracts under the tension of the reset spring, and drives the cleaning strip to move inward, thereby effectively cleaning the concrete attached to the bottom surface of the movable component, further preventing the concrete from condensing on the surface of the vibrating rod, and effectively reducing the labor intensity of the subsequent cleaning staff.

[0033] By setting a fixed component, which consists of a fixed ring, a fixed rod and a sealing ball, and setting an eccentric rotor, which consists of a rotating shaft, a counterweight plate and a counterweight block, when the eccentric rotor is working, since several movable blocks are arranged around the counterweight block, the movable blocks will approach the counterweight block one by one, and since there is a magnetic repulsion between the movable blocks and the counterweight block, the movable blocks are expanded. Moreover, since the eccentric rotor rotates at a high speed and the reset spring has mechanical inertia, the movable membrane is always in an expanded state due to the magnetic repulsion force. Moreover, since the fixed cavity of the fixed rod is connected with the movable groove of the movable membrane through the air inlet piece, the expansion of the movable membrane will generate a negative pressure environment in the fixed rod, effectively enhancing the effect of the fixed component in absorbing gas in concrete, thereby improving the effect of removing bubbles in concrete. When the eccentric rotor is not working, the movable membrane contracts and the excess gas in the movable membrane is discharged in time through the air outlet piece, so as to improve the working effect of the movable component and the fixed component on the concrete next time.

[0034] Furthermore, it also includes a driving mechanism and a transmission mechanism, one end of the transmission mechanism is connected to the driving mechanism, and the other end of the transmission mechanism is connected to the vibration rod.

[0035] Furthermore, the transmission mechanism includes:

[0036] A transmission member, wherein the output shaft of the driving mechanism is connected to one end of the transmission member, and the other end of the transmission member passes through the vibration shell and is connected to the top end of the rotating shaft. The transmission member is a flexible core shaft formed by tightly winding multiple layers of steel wire;

[0037] The transmission component is wrapped with a hose shell, and grease is filled between the hose shell and the transmission component.

[0038] The beneficial effects of the present invention are as follows:

[0039] The present application provides a concrete pouring equipment for construction construction, which comprises a fixed assembly fixedly sleeved on the outside of a vibrating rod and a movable assembly movably sleeved on the outside of the vibrating rod and the fixed assembly. When the vibrating rod is inserted into the concrete, the movable assembly is above the top surface of the concrete due to the surface buoyancy of the concrete. When the vibrating rod is pulled out of the concrete, the vibrating rod and the fixed assembly move upward while the movable assembly remains stationary, so that the movable assembly moves downward relative to the vibrating rod and the fixed assembly. This can not only effectively and timely clean the concrete fluid attached to the surface of the vibrating rod and the fixed assembly, prevent the concrete from condensing on the surface of the vibrating rod, and effectively reduce the labor intensity of cleaning for later workers, but also can replenish concrete at the pull-out position of the vibration mechanism, effectively reducing the difficulty of concrete leveling for later workers.

DETAILED DESCRIPTION

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0058] Example 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 hose housing 21 in the transmission mechanism 2 and the eccentric rotor 7 in the vibrating rod 4 to rotate. The driving mechanism 1 is placed in a working frame to facilitate the transportation of the driving mechanism 1.

[0059] like Figure 1-3One 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 vibrating rod 4, which is used to connect the driving mechanism 1 and the vibrating rod 4. The transmission mechanism 2 is flexible, which is convenient for the operator to flexibly move and insert the vibrating rod 4. The transmission mechanism 2 includes a hose housing 21 and a transmission member 22, such as Figure 3 and Figure 10 The output shaft of the driving mechanism 1 is connected to one end of the transmission member 22 through a connector (such as a coupling or a chuck), and the other end of the transmission member 22 passes through the vibration shell 41 and is connected to the top of the rotating shaft 71. The transmission member 22 is a flexible core shaft made of multiple layers of steel wire tightly wound. The core shaft has excellent torsional stiffness (can transmit torque) and flexibility (can bend). When the driving mechanism 1 rotates, its torque is directly transmitted to the transmission member 22 inside the hose housing 21, causing the transmission member 22 to rotate at high speed, thereby driving the eccentric rotor 7 to rotate at high speed. The outside of the transmission member 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 member 22. The design of the hose housing 21 can protect the transmission member 22 and prevent concrete, mortar, water or other debris from invading and damaging the transmission member 22. It can also reduce the friction resistance of the transmission member 22 during rotation, help dissipate heat and prevent rust, and prevent operators from contacting the high-speed rotating transmission member 22.

[0060] like Figure 2-Figure 3 The vibrating rod 4 includes a vibrating housing 41, a bearing 42 and an eccentric rotor 7, as shown in FIG. Figures 9-12 The bottom end of the vibration shell 41 is a smooth hemisphere, which is convenient for inserting into concrete. The vibration shell 41 is usually made of wear-resistant and impact-resistant steel to effectively protect its internal components. The inner upper end of the vibration shell 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 stably set the eccentric rotor 7 inside the vibration shell 41, thereby supporting the high-speed rotation of the eccentric rotor 7, and the vibration shell 41 vibrates under the centrifugal force of the eccentric rotor 7, so that the concrete inserted into the vibration rod 4 is tighter and stronger. It should be noted that a cooling system is provided inside the vibration shell 41, which can introduce cold air according to the temperature inside the vibration shell 41 to reduce the temperature inside it and prevent the vibration rod 4 from overheating and damage.

[0061] like Figure 7-Figure 8 、 Figure 13 The outer wall of the vibration shell 41 is fixedly sleeved with a fixing component 5, which can guide the gas in the concrete to be fully discharged.

[0062] like Figure 2-Figure 6 、 Figure 14-15 The fixed component 5 is movably connected to the movable component 6, and the inner ring of the movable component 6 is movably connected to the outer wall of the vibration shell 41, which can clean the concrete fluid adhering to the vibration rod 4 and the fixed component 5.

[0063] like Figure 1-Figure 2 In summary, the vibrating rod 4, the fixed component 5 and the movable component 6 constitute the vibrating mechanism 3, which is used to vibrate the concrete to eliminate bubbles in the concrete, make the concrete densely combined, and thus eliminate the honeycomb surface and other phenomena of the concrete, thereby improving the strength of the concrete and ensuring the quality of the concrete components.

[0064] When the vibrating rod 4 is pulled out from the concrete, the movable component 6 will move downward relative to the vibrating rod 4 and the fixed component 5, which can not only timely and fully clean the concrete fluid attached to the surface of the vibrating rod 4 and the fixed component 5, prevent the concrete from condensing on the surface of the vibrating rod, and effectively reduce the labor intensity of cleaning for later staff, but also can replenish concrete at the position where the vibrating rod 4 is pulled out, effectively reducing the difficulty of concrete leveling for later staff.

[0065] Example 2: Based on Example 1, the eccentric rotor 7 includes a rotating shaft 71, a counterweight plate 72 and a counterweight block 73, as shown in FIG. Figure 10-12 The rotating shaft 71 and the vibration shell 41 are concentrically arranged, and the bottom end of the rotating shaft 71 conflicts with the inner bottom end of the vibration shell 41, which effectively ensures the stability of the rotating shaft 71 working in the vibration shell 41. A counterweight plate 72 is fixedly connected to one side of the outer wall of the rotating shaft 71, and the counterweight plate 72 is located below the bearing 42. A vertical groove is opened in the middle of the counterweight plate 72, and the counterweight plate 72 is fixedly connected to the counterweight block 73 through the vertical groove. The shape design of the rotating shaft 71, the counterweight plate 72 and the counterweight block 73 effectively causes the eccentric rotor 7 to constitute a component with uneven mass distribution (eccentricity). When the component rotates at high speed, it generates a centrifugal force with a continuously and rapidly changing direction. This centrifugal force drives the vibrating rod 4 to generate high-frequency, small-amplitude circular vibration or elliptical vibration along its radial direction.

[0066] like Figure 12 A number of transverse holes are provided on 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 vibration shell 41 is the airflow inlet, and the port of the transverse hole facing the inner wall of the vibration shell 41 is the airflow outlet. When the eccentric rotor 7 rotates at high speed, the airflow will pass through the transverse holes, which not only dissipates the heat of the eccentric rotor 7 to cooperate with the cooling system to achieve sufficient cooling of the eccentric rotor 7, but also enables the outgoing airflow to impact the inner wall of the vibration shell 41, further enhancing the vibration effect of the vibration shell 41 and improving the vibration efficiency of the concrete.

[0067] Example 3: Based on Example 2, the fixing assembly 5 includes a fixing ring 51, a fixing rod 52 and a sealing ball 53. Figure 7-Figure 8 、 Figure 13, the number of fixing rings 51 is two, and one fixing ring 51 is threadedly sleeved on the outer wall of the upper half of the vibration shell 41, and the other fixing ring 51 is threadedly sleeved on the outer wall of the lower half of the vibration shell 41, which is convenient for disassembling and replacing the fixing component 5, and a fixing rod 52 is fixedly connected between the two fixing rings 51. The number of fixing rods 52 is several, and several fixing rods 52 are evenly arranged around the vibration shell 41. A fixing cavity is opened inside the fixing rod 52, which helps to fully discharge the gas in the concrete around the vibration shell 41. A plurality of fixing holes are opened on the side of the fixing ring 51 away from the vibration shell 41. The plurality of fixing holes are arranged in a vertical array, and the fixing holes are connected to the fixing cavity, so that the external gas can be absorbed into the fixing holes and then enter the fixing cavity. Figure 3-Figure 5 The fixing hole is composed of a truncated cone hole and a cylindrical hole, and the cylindrical hole is arranged between the fixing cavity and the truncated cone hole. A sealing ball 53 is arranged in the truncated cone hole. The outer wall of one side of the sealing ball 53 is adapted to the open end of the truncated cone hole, that is, when no vibration is performed, the sealing ball 53 can effectively close the truncated cone 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 truncated cone hole, that is, when vibration is performed, the eccentric rotor 7 generates a magnetic repulsive force on the movable component 6, which reduces the air pressure in the fixing cavity of the fixing rod 52, thereby generating an air pressure difference from the outside of the fixing ring 51 to the inside of the fixing ring 51. Under the action of the 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 conical hole, so that the gas in the concrete can enter the fixed ring 51 under the action of the negative pressure. Moreover, since the gap formed is small, large particles of building materials such as concrete cannot enter, thereby better eliminating bubbles in the concrete and improving the density of the concrete. A waterproof and breathable membrane is fixedly sleeved in the cylindrical hole, so that the water in the concrete can be blocked outside the fixed cavity of the fixing rod 52, while the gas in the concrete can pass through to prevent water from affecting the negative pressure environment inside the fixing rod 52.

[0068] Example 4, based on Example 3, Figure 11-12 The counterweight 73 is an electromagnet, and whether the counterweight 73 is energized is related to whether the shaft 71 rotates. When the shaft 71 rotates, the counterweight 73 is energized, and when the shaft 71 does not rotate, the counterweight 73 is de-energized. Figure 3 、 Figure 6 When power is turned on, the end of the counterweight block 73 close to the inner wall of the vibration shell 41 has S-type magnetism, and the end of the counterweight block 73 away from the inner wall of the vibration shell 41 has N-type magnetism. The magnetic pole direction design of the counterweight block 73 is used to magnetically control the movable component 6 to better eliminate bubbles during operation.

[0069] like Figure 2 、 Figure 14-15The movable assembly 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 shown in FIG. Figure 5-Figure 6 The inner ring of the movable plate 61 is movably connected to the vibration shell 41 surrounded by 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 vibration rod 4 and the fixed component 5. A number of tiny air holes are vertically opened on the movable plate 61, which can not only reduce the mass of the movable plate 61 and make the movable plate 61 always float on the surface of the concrete, but also can not hinder the effective discharge of gas in the concrete. The outer ring of the movable plate 61 is provided with a movable groove, and the movable membrane 62 is interference-fitted in the movable groove of the movable plate 61, and one end of the movable membrane 62 is fixedly connected to the side of the movable groove close to the vibration shell 41, and the other end of the movable membrane 62 is movably connected to the side of the movable groove away from the vibration shell 41. The movable membrane 62 corresponds to the fixed rod 52 one by one, and the deformation of the movable membrane 62 caused by the transition between the contracted state and the extended state is used to move the concrete adhered to the bottom end of the movable membrane 62. The movable block 63 is fixedly connected to the inner wall surface of the movable membrane 62 away from the fixed rod 52, and the movable block 63 is connected to the movable plate 61 by a return spring. When the eccentric rotor 7 is not working, the movable block 63 is pulled toward the vibration shell 41 under the pulling force of the return spring, thereby realizing the contraction of the movable membrane 62. The movable block 63 is a permanent magnet, and the side of the movable block 63 close to the vibration shell 41 has S-type magnetism, and the side of the movable block 63 away from the vibration shell 41 has N-type magnetism. When the eccentric rotor 7 is working, since several movable blocks 63 are arranged around the counterweight block 73, the counterweight block 73 will be close to each movable block 63, so that the counterweight block 73 will generate a magnetic repulsion force on each movable block 63, thereby realizing the expansion of the movable membrane 62. Because the counterweight block 73 rotates at a high speed, the return spring cannot be contracted in time due to mechanical inertia, so that the movable block 63 is always in the expanded state. Figure 4-Figure 5One 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. The other end of the air inlet member 64 is fixedly connected to the internal top of the fixed rod 52. The air inlet member 64 is used to connect the movable membrane 62 with the internal top 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 stretches, its volume increases and the air pressure decreases, which effectively reduces the air pressure in the fixed rod 52. That is, the expansion of the movable membrane 62 will generate a negative pressure environment in the fixed rod 52, effectively enhancing the effect of the fixed component 5 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 internal top of the movable membrane 62. The other end of the air outlet member 65 is connected to the outside world. 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 a 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 exhausting excess gas, so as to improve the effect of eliminating bubbles in the concrete next time. The bottom end of the movable membrane 62 located below the movable block 63 is fixedly connected to a cleaning strip 66. The cleaning strip 66 is arc-shaped and fits the bottom surface of the movable plate 61. The two adjacent cleaning strips 66 are staggered. When the movable membrane 62 drives the cleaning strip 66 to move, the concrete fluid adhering to the bottom end of the movable plate 61 can be effectively cleaned.

[0070] The working principle of the method of use of the present invention is as follows:

[0071] First, the staff holds the transmission mechanism 2 to insert the vibrating rod 4 into the concrete, and the fixed component 5 follows the vibrating rod 4 to enter synchronously. During this process, the movable component 6 is above the top surface of the concrete due to the surface buoyancy of the concrete. Afterwards, the eccentric rotor 7 is driven by the driving mechanism 1 to rotate at high speed to drive the vibration shell 41 to vibrate, thereby vibrating the concrete. Afterwards, the staff pulls out the vibrating rod 4, and the fixed component 5 follows the vibrating rod 4 to be pulled out synchronously. During this process, the movable component 6 still floats above the top surface of the concrete, so that the movable component 6 moves downward relative to the vibrating rod 4 and the fixed component 5, so that the movable component 6 can effectively and timely clean the concrete fluid attached to the surface of the vibrating rod 4 and the fixed component 5, which can not only prevent the concrete from condensing on the surface of the vibrating rod, effectively reducing the labor intensity of the later cleaning staff, but also can replenish concrete at the pull-out position of the vibration mechanism 3, effectively reducing the difficulty of the later staff in leveling the concrete.

[0072] During the high-speed rotation of the eccentric rotor 7, since the counterweight plate 72 is provided with an S-shaped horizontal hole, the air flow will pass through the S-shaped horizontal hole, which not only effectively dissipates the heat of the eccentric rotor 7 to cooperate with the cooling system to achieve sufficient and rapid cooling of the eccentric rotor 7, but also enables the outgoing air flow to impact the inner wall of the vibration shell 41, further enhancing the vibration effect of the vibration shell 41 and improving the vibration efficiency of the concrete.

[0073] 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.

[0074] 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.
