Description

Technical Field

[0001] The utility model relates to the field of concrete compaction equipment, and particularly relates to a concrete vibration device. Background Art

[0002] A concrete vibration device is a vibration equipment used in the processes of concrete mixing and forming. Its main function is to improve the fluidity, uniformity and strength of concrete through vibration, so as to improve the quality of concrete products. A concrete vibration device generally consists of a motor, a vibration mechanism, a control system and a bracket, etc. The motor provides the vibration force, the vibration mechanism transmits the vibration force to the concrete, the control system controls the vibration frequency and amplitude, and the bracket fixes the vibration device.

[0003] Due to different requirements for concrete strength and different ratios of aggregates, concrete with higher strength requirements often has a higher proportion of stones. Therefore, a vibration device with a higher frequency and deeper penetration is needed, so that the sand and cement between the stones can be better filled. For the compaction of concrete with a high proportion of stones, a vibrating rod is generally used for vibration, while a flat vibration device is more suitable for scenarios with a high proportion of sand or cement. The vibrating rod has a better vibration effect but a small vibration area. And because the coverage range of the storage hopper of the mixer is limited, before vibration, the concrete needs to be roughly leveled to facilitate vibration, which requires manual or special machines for leveling, consuming time and effort.

[0004] The Chinese invention patent with the application number CN201510156120.5 discloses a concrete vibration device, which includes a feeding hopper arranged at the upper end of a concrete trolley, a concrete discharge port arranged at the lower right end of the concrete trolley, a discharge control valve inserted inside the concrete discharge port, a concrete paving plate arranged at the left bottom of the concrete trolley, and a leveling vibration plate connected to the lower end of the concrete paving plate. The purpose of laying and vibrating at the same time is achieved. However, due to the small space of the concrete trolley and limited loaded concrete, the concrete trolley needs to be loaded with concrete multiple times when laying concrete over a large area, resulting in low efficiency. At the same time, the vibration effect of this solution is limited in the case of a large amount of stones. Content of the Utility Model

By providing a vibrating plate with a special-shaped cone and inserting the special-shaped cone into the concrete for vibration, the compaction effect of the concrete is effectively improved; by providing a leveling mechanism to level the concrete in the moving direction of the vibrating plate, the flatness of the concrete is effectively improved, thereby improving the efficiency and effect of concrete vibration; by providing a supporting mechanism to support the vibrating plate, the depth of the vibrating plate sinking into the concrete is reduced, so that more force is required to push forward, and at the same time, the concrete beside the vibrating plate can be leveled to a certain extent.

Detailed Embodiments

[0021] To better understand the structure of the present utility model and the functional features and advantages that can be achieved, the following will describe the preferred embodiments of the present utility model in detail in conjunction with the drawings as follows:

[0022] Embodiment:

[0023] As shown in Figures 1 to 3 As shown, the present utility model provides a concrete vibrating device, which includes a vibrating plate 1, a fixed seat 2 and a support column 21. The vibrating plate 1 is usually square or circular and contacts the concrete surface. The high-frequency vibration of the vibrating plate 1 compacts the concrete. One end of the support column 21 is fixedly connected to the vibrating plate 1, and the other end of the support column 21 passes through the bottom wall of the fixed seat 2 and abuts against a vibration mechanism 3 for vibrating the vibrating plate 1. The vibration mechanism 3 is placed inside the fixed seat 2.

[0024] The vibration mechanism 3 includes an eccentric motor 31, a limiting plate 32 and a spring 33. The eccentric motor 31 is fixedly connected inside the fixed seat 2, and the output end of the eccentric motor 31 abuts against the support column 21. The limiting plates 32 are respectively placed on both sides of the bottom wall of the fixed seat 2 and are fixedly connected to the support column 21. The spring 33 is sleeved outside the support column 21 and is located between the bottom wall of the fixed seat 2 and the upper limiting plate 32. During the rotation of the eccentric motor 31, the protruding part abuts against the support column 21 to press down the support column 21, and the spring 33 resets the support column 21, so as to achieve high-frequency vibration reciprocally. The support column 21 is fixedly connected with a plurality of support rods 211. One end of the support rod 211 is fixedly connected to the support column 21, and the other end of the support rod 211 is fixedly connected to the vibrating plate 1. A plurality of support rods 211 can be evenly arranged to keep the vibrating plate 1 horizontal and improve durability. In addition, the vibration can be better conducted to the edge of the vibrating plate 1.

[0025] As another embodiment, as shown in Figure 1 and Figure 4 As shown, a special-shaped cone 4 for penetrating into the concrete is fixedly connected to the bottom wall of the vibrating plate 1 of the present application. The special-shaped cone 4 is inserted into the concrete, and when the vibrating plate 1 vibrates, the vibration is conducted into the deep concrete, so that the bottom of the concrete with more stones is fully vibrated to reduce the gap between the stones. The special-shaped cone 4 is fixedly connected to the bottom wall of the vibrating plate 1 through a connecting rod 41. The side of the special-shaped cone 4 facing the advancing direction of the vibrating plate 1 and the side in contact with the concrete protrude or extend. Each tip of the special-shaped cone 4 has a certain arc surface to reduce the probability of damage to the tip when the special-shaped cone 4 collides with the stones. The opposite side of the special-shaped cone 4 in the advancing direction of the vibrating plate 1 is also in the shape of a sharp cone, so that when the special-shaped cone 4 advances, the surrounding concrete can be immediately supplemented to the tail, which can effectively improve the compaction effect.

[0026] As another embodiment, as shown in Figure 2 and Figure 5As shown, a leveling mechanism 5 for leveling concrete is provided in the forward side gap of the vibrating plate 1 of the present application. The leveling mechanism 5 is rotatably connected to the fixed seat 2. Since the concrete needs to be discharged from the mixer first when laying the concrete, the concrete will be scattered and piled up, and workers need to level the concrete first and then vibrate it solid. Therefore, the leveling mechanism 5 can level the concrete before vibrating it solid, effectively reducing the labor intensity and difficulty of the workers.

[0027] The leveling mechanism 5 includes a scraping plate 51, a rotating rod 52, a swinging plate 53, two baffle plates 54, a DC motor 55 and a cam 56. The rotating rod 52 passes through the bottom wall of the fixed seat 2. One side of the rotating rod 52 is fixedly connected to the scraping plate 51, and the other side of the rotating rod 52 is fixedly connected to the swinging plate 53. The swinging plate 53 is placed inside the fixed seat 2. The DC motor 55 is fixedly connected inside the fixed seat 2, and the output end of the DC motor 55 is fixedly connected to the cam 56. The two baffle plates 54 are located on both sides of the cam 56, and the baffle plates 54 are in contact with the cam 56. The distance from the baffle plate 54 to the output end of the DC motor 55 is less than the distance from the end of the cam 56 to the output end of the DC motor 55. The baffle plate 54 is fixedly connected to the swinging plate 53. When the cam 56 is rotated by the DC motor 55 and driven to rotate, the relatively pointed side of the cam 56 presses the baffle plate 54, and the baffle plate 54 drives the swinging plate 53 to deflect to one side along the rotating rod 52. As the cam 56 continues to rotate, when the cam 56 presses against the other baffle plate 54, the baffle plate 54 drives the swinging plate 53 to offset to the other side along the rotating rod 52. A torsion spring can be connected between the rotating rod 52 and the fixed seat 2 to help the swinging plate 53 reset. Since both the scraping plate 51 and the swinging plate 53 are fixedly connected to the rotating rod 52, the scraping plate 51 can also swing reciprocally. When the swinging scraping plate 51 advances compared to the non-moving scraping plate 51, it can more smoothly scrape the concrete in front, reducing the probability that the scraping plate 51 cannot be pushed or is laborious to advance due to excessive accumulation of concrete.

[0028] A snap ring 521 is fixedly connected to the side of the rotating rod 52 close to the baffle plate 54. The snap ring 521 is located inside the fixed seat 2 and is in contact with the fixed seat 2. The snap ring 521 can limit the up and down position of the rotating rod 52 and improve the running stability.

[0029] As another embodiment, as Figure 1 and Figure 2As shown in the figure, a supporting mechanism 6 for supporting the vibrating plate 1 is detachably connected to the side of the vibrating plate 1 of the present application, so that the vibrating plate 1 moves on the concrete surface. The supporting mechanism 6 includes a supporting plate 61 and a folding rod 62. One end of the folding rod 62 is fixedly connected to the side wall of the vibrating plate 1, and the other end of the folding rod 62 is fixedly connected to the supporting plate 61. The supporting plate 61 is located on both sides of the vibrating plate 1 and on both sides of the scraping plate 51. The distance between the supporting plate 61 and the concrete is greater than the distance between the vibrating plate 1 and the concrete. The main function of the supporting plate 61 is to reduce the probability that the vibrating plate 1 may extend into the concrete due to the installation of the special-shaped cone 4 during vibration, thereby increasing the resistance when the vibrating plate 1 advances. In addition, the supporting plate 61 of the vibrating plate 1 can be made arc-shaped to reduce the probability of increasing the resistance when the supporting plate 61 is inserted into the concrete.

[0030] The working principle of a concrete vibrating device of the present application: During use, first, the concrete is discharged to the position to be laid by a mixer. The concrete with a large accumulation volume can be preliminarily leveled by manual or professional equipment in advance. If the accumulation volume is small, the device of the present application can be directly used. When the DC motor 55 and the eccentric motor 31 are turned on and advancing forward, the DC motor 55 drives the cam 56 to rotate. During the rotation of the cam 56, it squeezes the baffle plates 54 on both sides, so that the swing plate 53 swings. Since both the scraping plate 51 and the swing plate 53 are fixedly connected to the rotating rod 52, when the swing plate 53 swings, the scraping plate 51 can also swing to scrape the concrete in front. At the same time, during the rotation of the eccentric motor 31, its eccentric part abuts against the support column 21 and presses down the support column 21. The spring 33 plays a role in supporting and resetting the support column 21. In this way, the support column 21 realizes vibration, and the vibration is transmitted to the vibrating plate 1 through the support rod 211 and the support column 21 itself. The special-shaped cone 4 on the vibrating plate 1 is inserted into the concrete. Therefore, when the vibrating plate 1 vibrates, the special-shaped cone 4 will also vibrate, and the gaps between the stones inside the concrete can be vibrated and compacted. During the forward movement, the supporting plate 61 effectively keeps the vibrating plate 1 on the surface of the concrete, reducing the probability that the vibrating plate 1 increases the resistance due to sinking into the concrete surface layer.

[0031] The above is only a preferred embodiment of the present utility model, and does not impose any form of limitation on the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the above technical content without departing from the scope of the technical solution of the present utility model, or modify it into an equivalent embodiment with equivalent changes. Therefore, all changes, modifications, equivalent changes and modifications made to the above embodiments based on the technical solution of the present utility model without departing from the content of the technical solution of the present utility model belong to the protection scope of this technical solution.
