[0003] The existing screen vibration mechanism is single vibrator and circular vibration, and when the concrete screen vibrates around the shaft, additional radial force is applied to the rotating shaft of the concrete screen, which reduces the service life of the concrete screen, and the noise is large when the concrete screen vibrates, and the construction environment is poor. SUMMARY

[0004] The utility model discloses to solve the problem of additional radial force and large noise of the concrete screen in the prior art, and provides a concrete screen vibration device, which can make the concrete screen obtain linear vibration, so that the concrete screen vibrates around the rotating shaft in a single linear vibration form, solves the problem of additional radial force and large noise when the concrete screen vibrates around the shaft, and prolongs the service life of the concrete screen.

[0005] In order to achieve the above purpose, the technical scheme of the utility model is as follows: a concrete screen vibration device, comprising a hopper, further comprising a concrete screen movably arranged in the hopper, the hopper is provided with a rotating seat symmetrically, and a lap plate is fixedly arranged on one side of the hopper. The hopper plays the role of containing concrete and supporting the concrete screen, the rotating seat plays the role of supporting the rotating assembly, so that the concrete screen can be rotated and vibrated through the action of the rotating assembly, and the lap plate plays the role of supporting the concrete screen.

[0006] One end of the concrete screen overlaps the top of the overlapping plate, and the other end of the concrete screen has symmetrically arranged rotating components at its top, which are rotatably connected to the rotating base. A vibration component is also provided on the top of the concrete screen, comprising a support and a vibrator. The support is located on top of the concrete screen, and the vibrators are symmetrically arranged on top of the support. The support supports the vibrators, which provide power for the vibration of the concrete screen, causing the concrete screen and the vibrator to vibrate together around the rotating component, thus screening out large-diameter stones and impurities from the concrete. The symmetrical installation of the vibrators, with their excitation forces coplanar and opposite in direction, eliminates forces in other directions, achieving the effect of the concrete screen vibrating around the rotating component in a single vibration mode.

[0007] Furthermore, a baffle plate with a "U"-shaped structure is provided at the top edge of the hopper, and through holes are opened at both ends of the baffle plate. The baffle plate serves to stop the material from falling outside the hopper during the process of conveying concrete into the hopper.

[0008] Furthermore, the rotating assembly includes a fixed plate and a rotating shaft. The fixed plate is vertically disposed on the top of the concrete screen. One end of the rotating shaft is connected to the fixed plate, and the other end passes through the through hole and is rotatably connected to the rotating seat. Through the cooperation of the rotating shaft, the fixed plate, and the rotating seat, the concrete screen is driven to vibrate around the rotating shaft when the vibrator vibrates, so that the concrete screen obtains the linear vibration of the vibrator.

[0009] Furthermore, the rotating seat is located outside the baffle plate. The rotating seat includes a nylon bushing and two clamping blocks. The nylon bushing is fixedly disposed between the two clamping blocks. One end of the rotating shaft is sleeved inside the nylon bushing and rotatably connected to the nylon bushing. The two clamping blocks clamp and fix the nylon bushing, so that the rotating shaft and the nylon bushing cooperate to make the concrete screen vibrate linearly around the rotating shaft.

[0010] Furthermore, both clamping blocks are provided with arc-shaped grooves that match the nylon bushing. The two clamping blocks are bolted together and arranged opposite each other. The arc-shaped grooves on the clamping blocks facilitate the clamping and fixing of the nylon bushing.

[0011] Furthermore, the top of the concrete screen is symmetrically equipped with handles, which are in the shape of an inverted "U". The handles allow workers to manually rotate the concrete screen to remove large-diameter stones and debris screened out by the screen.

[0012] Furthermore, the support includes a horizontal part and an inclined part, with the inclined part provided on both sides of the horizontal part. The inclined part is fixedly connected to the concrete screen, and the included angle between the inclined part and the horizontal part is an obtuse angle, the purpose of which is to provide overall stability of the support.

[0013] Furthermore, there are two vibrators arranged side by side on the top of the support. The vibrators are detachably bolted to the support. The purpose is to make the excitation forces of the two vibrators coplanar and opposite in direction, eliminate forces in excess direction, and adjust the resultant excitation force of the two vibrators to be perpendicular to the support.

[0014] The beneficial effects of this utility model through the above technical solution are as follows:

[0015] This utility model has a reasonable structure and good performance. It enables the concrete screen to obtain linear vibration from the vibrator, and allows the concrete screen to vibrate around the rotation axis in a single linear vibration form based on the obtained linear vibration. This eliminates the additional radial force when the concrete screen vibrates around the axis, thus avoiding the application of additional radial force to the rotation axis of the concrete screen and extending the service life of the concrete screen. At the same time, it also reduces the noise of the concrete screen vibration, improves the construction environment, and solves the problems of additional radial force and high noise when the concrete screen vibrates around the axis.

[0016] The rotating shaft of this utility model's rotating assembly cooperates with a fixed plate and a nylon bushing of a rotating seat. By overlapping the concrete screen onto the overlapping plate, the vibrator can drive the concrete screen to vibrate around the rotating shaft when it vibrates. The vibrator provides power for the vibration of the concrete screen, and the support of the vibrator enables the concrete screen to obtain the power for vibration.

[0017] This invention involves symmetrically installing two vibrators side-by-side on the top of a support, so that the excitation forces of the two vibrators are coplanar and rotate in opposite directions, eliminating forces in unnecessary directions, and adjusting the resultant excitation forces of the two vibrators to be perpendicular to the support. This achieves the purpose of obtaining linear vibration of the concrete screen by the combination of two vibrators and reducing noise, thus realizing the effect of the concrete screen vibrating around the rotation axis in a single linear vibration form.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] like Figures 1 to 5 As shown, a concrete screen vibration device includes a hopper 1 and a concrete screen 4 movably disposed inside the hopper 1. Rotating seats 10 are symmetrically arranged on the hopper 1, and overlapping plates 3 are fixedly disposed on one side of the inside of the hopper 1. In this embodiment, the hopper 1 is a concrete wet spraying trolley hopper, which serves to hold concrete and support the concrete screen 4. When concrete is conveyed into the hopper 1, it can screen out large-diameter stones and impurities in the concrete. There are two rotating seats 10, which cooperate with a rotating assembly to allow the concrete screen 4 to rotate and vibrate under the action of a vibrator. There are two overlapping plates 3, which are symmetrically welded and fixed to one side of the inside of the hopper 1. The overlapping plates 3 support one end of the concrete screen 4 to facilitate vibration of the concrete screen 4 around the rotating assembly.

[0026] One end of the concrete screen 4 overlaps the top of the overlapping plate 3, and the other end of the concrete screen 4 is symmetrically provided with a rotating component, which is rotatably connected to the rotating seat 10; the top of the concrete screen 4 is also provided with a vibration component, which includes a support 6 and a vibrator 7. The support 6 is provided on the top of the concrete screen 4, and the vibrator 7 is symmetrically provided on the top of the support 6. In this embodiment, the purpose of overlapping one end of the concrete screen 4 with the top of the overlapping plate 3 is to facilitate the vibration of the concrete screen 4 around the rotating assembly.

Through the cooperation of the rotating assembly and the rotating seat, and by overlapping the concrete screen 4 with the overlapping plate 3, the vibrator 7 can drive the concrete screen 4 to vibrate around the rotating assembly when it vibrates. The support 6 is welded and fixed to the concrete screen 4. There are two vibrators 7 on the top of the support 6. When the vibrator 7 vibrates, it transmits the vibration to the concrete screen 4 through the support 6. The two vibrators 7 are symmetrically installed on the top of the support 6 so that the excitation forces of the two vibrators 7 are coplanar and rotate in opposite directions, eliminating the force in the extra direction and adjusting the resultant force of the excitation forces of the two vibrators 7 to be perpendicular to the support 6.

[0027] A baffle plate 2 with a "U" - shaped structure is provided at the top edge of the hopper 1, and through - holes are opened at both ends of the baffle plate 2. In this embodiment, when conveying concrete to the hopper 1, under the action of the baffle plate 2, it can prevent the concrete from falling outside the hopper 1. The baffle plate 2 plays a role in blocking the concrete, and the baffle plate 2 is made of rubber material.

[0028] The rotating component includes a fixing plate 8 and a rotating shaft 9. The fixing plate 8 is vertically arranged at the top of the concrete sieve 4. One end of the rotating shaft 9 is connected to the fixing plate 8, and the other end passes through the through - hole and is rotatably connected to the rotating seat 10. In this embodiment, the fixing plate 8 is welded and fixed on the concrete sieve 4. The number of fixing plates 8 for each rotating component is two. The rotating shaft 9 is fixedly sleeved on the fixing plate 8, and the rotating shaft 9 is also rotatably connected to the baffle plate 2 through the through - hole. Through the through - hole, it is convenient for the rotating shaft 9 to pass through the baffle plate 2 and be connected to the rotating seat 10.

[0029] The rotating seat 10 is located outside the baffle plate 2. The rotating seat 10 includes a nylon bushing 12 and two clamping blocks 11. The nylon bushing 12 is fixedly arranged between the two clamping blocks 11. One end of the rotating shaft 9 is sleeved in the nylon bushing 12 and is rotatably connected to the nylon bushing 12. In this embodiment, through the mutual cooperation of the two clamping blocks 11, the nylon bushing 12 is clamped and fixed. When the vibrator 7 vibrates, it is convenient for the concrete sieve 4 to rotate and vibrate through the cooperation of the rotating shaft 9 and the nylon bushing 12, so as to achieve the purpose of screening large - sized stones and sundries in the concrete.

[0030] Arc - shaped grooves matching the nylon bushing 12 are opened on both of the two clamping blocks 11, and the two clamping blocks 11 are bolt - connected and arranged oppositely. In this embodiment, through the action of the arc - shaped grooves on the two clamping blocks 11, it is convenient for the two clamping blocks 11 to clamp and fix the nylon bushing 12 through bolts.

[0031] Lifting handles 5 are symmetrically arranged at the top of the concrete sieve 4, and the lifting handles 5 have an inverted "U" - shaped structure. In this embodiment, the number of lifting handles 5 is two, and both ends of the vertical part of the lifting handle 5 are welded and fixed on the concrete sieve 4. When there are more large - sized stones and sundries on the concrete sieve 4, the staff can manually rotate the concrete sieve 4 through the lifting handles 5 to lift the concrete sieve 4 and clean the large - sized stones and sundries.

[0032] The support 6 includes a horizontal part and an inclined part. The inclined parts are arranged on both sides of the horizontal part, and the inclined part is fixedly connected to the concrete sieve 4. The included angle between the inclined part and the horizontal part is an obtuse angle. In this embodiment, the lower ends of the two inclined parts of the support 6 are both welded and fixed to the concrete sieve 4. The purpose of the included angle between the inclined part and the horizontal part being an obtuse angle is to improve the overall stability of the support 6.

[0033] The number of vibrators 7 is two, and the two vibrators 7 are arranged side by side on the top of the support 6. The vibrators 7 are detachably bolted to the support 6. In this embodiment, the two vibrators 7 are symmetrically installed side by side on the top of the support 6 so that the excitation forces of the two vibrators 7 are coplanar and rotate in opposite directions, eliminating forces in unnecessary directions, and adjusting the resultant force of the excitation forces of the two vibrators 7 to be perpendicular to the support 6, so as to achieve the effect of the concrete screen 4 vibrating around the rotation axis 9 in a single linear vibration form.

[0034] The working principle of this utility model is as follows: When concrete is conveyed to the hopper 1, two vibrators 7 are turned on. The two vibrators 7 transmit vibration to the concrete screen 4 through the support 6. Since the two vibrators 7 are installed symmetrically side by side on the top of the support 6, the excitation forces of the two vibrators 7 are coplanar and rotate in opposite directions, which can eliminate the force in the extra direction. Thus, the resultant force of the excitation forces of the two vibrators 7 is perpendicular to the support 6, and the linear vibration is transmitted to the concrete screen 4. In this way, the concrete screen 4 can obtain the linear vibration of the two vibrators 7. The concrete screen 4 vibrates up and down in a cycle and drives the rotating shaft 9 of the two rotating components to rotate in the nylon bushing 12. This achieves the effect of the concrete screen 4 vibrating around the rotating shaft 9 in a single linear vibration form, eliminating the extra radial force when the concrete screen 4 vibrates around the rotating shaft 9 and reducing the noise generated when the concrete screen 4 vibrates.
