Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rapid-hardening concrete processing, and particularly relates to a rapid-hardening concrete blanking and sorting device. Background Art
[0002] Rapid-hardening concrete is a kind of concrete, which is different from traditional concrete. Rapid-hardening concrete has a fast setting speed and a short formation time of the concrete structure strength. Since rapid-hardening concrete can form the concrete structure strength in a short time, it is widely used in industry. Rapid-hardening concrete is mostly used in the construction of large buildings. By using its advantage of rapid setting to form concrete strength, it can not only speed up the construction progress, but also quickly form the structure strength.
[0003] Therefore, rapid-hardening concrete is mostly high-standard concrete with high consistency. During the production of rapid-hardening concrete, the prepared concrete needs to be discharged quickly to avoid coagulation due to too slow discharging time. However, during the discharging process, due to the high viscosity of rapid-hardening concrete itself, the fluidity of the concrete is very poor during discharging. For example, after the concrete is discharged into the hopper, the concrete with very poor fluidity passes through the material pipe at the bottom of the hopper too slowly, resulting in easy coagulation and blockage of the concrete at the bottom of the hopper, and then leading to a serious reduction in the discharging speed. The concrete is exposed to the air for a long time, resulting in coagulation of a large amount of concrete.
[0004] Therefore, during the actual working process, when the discharging equipment pours the concrete into the hopper, the operator repeatedly knocks on the bottom of the hopper to promote the rapid passage of the concrete with very poor fluidity, facilitating the rapid progress of discharging and avoiding speed retardation.
[0005] However, during the actual working process, due to the large production volume of production enterprises and the large discharging volume of the discharging process, the construction personnel need to control the discharging machinery while assisting in knocking for discharging, resulting in a very large discharging workload. And once the auxiliary knocking for discharging fails to be carried out in time, the concrete quickly retards.
[0006] Therefore, how to assist the discharging of high-standard concrete with poor fluidity in a fast, effective and non-manual operation manner during the production process is crucial for improving the discharging efficiency. Summary of the Utility Model
[0007] Based on the above background, the purpose of the utility model is to provide a rapid-hardening concrete blanking and sorting device.
[0008] To achieve the above purpose, the utility model adopts the following technical solutions:
[0009] A rapid-hardening concrete blanking and sorting device includes a blanking and sorting hopper, and a sorting screen rod is fixedly connected inside the blanking and sorting hopper;
[0010] The quick-setting concrete feeding and sorting device further includes a vibrating feeding mechanism for vibrating at the bottom of the feeding and sorting hopper;
[0011] The vibrating feeding mechanism includes a number of vibrating units. Each vibrating unit includes a rotating motor, the output shaft of the rotating motor is fixedly connected with a rotating seat, an elastic vibrating rod is fixedly connected to the inner side wall of the rotating seat, and an elastic vibrating ball is fixedly connected to the inner end of the elastic vibrating rod;
[0012] During the feeding process, thick concrete slurry is fed into the feeding and sorting hopper. The reciprocally rotating elastic vibrating rod and elastic vibrating ball impact the bottom of the feeding and sorting hopper, assisting the thick concrete slurry to be discharged downward from the bottom discharge port of the feeding and sorting hopper.
[0013] Preferably, the feeding and sorting hopper includes a cylindrical part, and a conical part is integrally formed at the bottom of the cylindrical part;
[0014] The elastic vibrating rod and elastic vibrating ball impact the bottom of the conical part.
[0015] Preferably, the vibrating feeding mechanism further includes an annular frame fixedly connected at a position below the cylindrical part. A number of connecting plates are respectively installed at the top and bottom of the annular frame, and the rotating motor is fixedly assembled between the connecting plates.
[0016] Preferably, a number of L-shaped hanging plates are fixedly connected to the top of the annular frame, and the L-shaped hanging plates are fastened to the lower end position of the outer side wall of the cylindrical part by bolts.
[0017] Preferably, a connecting shaft is fixedly connected to the rotating seat, and an internal convex seat for rotatably connecting the connecting shaft is welded to the inner side wall of the annular frame;
[0018] The output shaft of the rotating motor is installed on the connecting shaft.
[0019] Preferably, a reinforcing spring is sleeved on the elastic vibrating rod, and the inner and outer ends of the reinforcing spring are respectively fixedly connected to the rotating seat and the elastic vibrating ball.
[0020] Preferably, the elastic vibrating rod and elastic vibrating ball are made of rubber material.
[0021] Preferably, a discharge pipe is integrally formed at the bottom of the conical part, and the discharge pipe is communicated with a long discharge pipe.
[0022] Preferably, the discharge pipe and the long discharge pipe are communicated through a spring pipe assembly. The spring pipe assembly includes a spring pipe, and the two ends of the spring pipe are respectively communicated to the discharge pipe and the long discharge pipe through flanges.
[0023] Preferably, a plurality of upper hanging ear plates are fixedly connected to the lower end of the outer side wall of the blanking and sorting hopper.
[0024] The utility model has the following beneficial effects:
[0025] 1. An elastic vibrating rod is fixedly connected to the inner side wall of the rotating seat, and an elastic vibrating ball is fixedly connected to the inner end of the elastic vibrating rod; the elastic vibrating rod and the elastic vibrating ball are made of rubber. By using the excellent elastic performance of the rubber material, during the working process, driven by the rotating motor, the elastic vibrating rod - elastic vibrating ball rotates clockwise and counterclockwise repeatedly and strikes at the bottom position of the blanking and sorting hopper, so as to vibrate and strike the bottom of the blanking and sorting hopper to increase the vibration of the high-consistency concrete at the bottom of the blanking and sorting hopper and assist its blanking.
[0026] In this way, since the rotating motor drives the elastic vibrating rod - elastic vibrating ball to vibrate and strike repeatedly without interruption during the blanking process, no matter how high the consistency of the concrete is, it can be blanked quickly in this way, maintaining the uninterrupted blanking and discharging smoothly at a very high fluidity. Furthermore, the blanking efficiency is improved.
[0027] 2. By sleeving a reinforcing spring on the elastic vibrating rod, the elastic impact force of the elastic vibrating rod and the elastic vibrating ball is improved. Specifically, when the elastic vibrating rod and the elastic vibrating ball strike the bottom of the conical part, at this time, the elastic vibrating rod deforms and bends, and the sleeved reinforcing spring deforms and bends synchronously. In this way, the elastic force is increased, and under the elastic restoring force of the reinforcing spring and the elastic vibrating rod made of elastic material, after resetting, the reinforcing spring and the elastic vibrating rod carry the elastic vibrating ball and strike the bottom of the conical part forcefully, so as to improve the effect of discharging the concrete downward.

[0038] Embodiment 1
[0039] As Figures 1-5 shown, a quick-setting concrete feeding and sorting device includes a feeding and sorting hopper 1 (the shape of the feeding and sorting hopper 1 is: the feeding and sorting hopper 1 includes a cylindrical part, and a conical part is integrally formed at the bottom of the cylindrical part). At the same time, according to the fixed installation method of the existing feeding and sorting hopper 1, a plurality of upper hanging ear plates 12 are fixedly connected to the lower end of the outer side wall of the feeding and sorting hopper 1. The feeding and sorting hopper 1 is installed on a hopper rack through the hanging ear plates 12.
[0040] A sorting sieve rod 11 is fixedly connected inside the blanking and sorting hopper 1 (the sorting sieve rod 11 is formed by welding a number of steel bars. Adjacent steel bars form a sorting gap. A large amount of mortar passes through the gap, while large stones are intercepted on the sorting sieve rod). By means of the sorting sieve rod 11, during the process of blanking rapid hardening concrete, large stones in the concrete (the large stones are large stones in the aggregate that have not been effectively removed and sorted) are intercepted to prevent them from mixing into the concrete. In this way, it is further ensured that the directly used concrete does not contain large stones.
[0041] In order to address the difficulties in blanking high-strength concrete with poor fluidity, such as easy stagnation, blockage, and slow blanking speed during the blanking process, the following improvements are made:
[0042] The rapid hardening concrete blanking and sorting device further includes a vibrating blanking mechanism 3 for vibrating at the bottom of the blanking and sorting hopper 1.
[0043] Specifically, the vibrating blanking mechanism 3 includes a number of vibrating units. During the working process, each vibrating unit vibrates and knocks at the bottom of the conical part to assist the blanking of concrete with poor fluidity.
[0044] Specifically, the vibrating unit includes a rotating motor 31, and the output shaft of the rotating motor 31 is fixedly connected with a rotating seat 33.
[0045] Specifically, a connecting shaft 32 is fixedly connected to the rotating seat 33, and the output shaft of the rotating motor 31 is installed on the connecting shaft 32. The specific method is the same as the existing method: the output shaft of the rotating motor 31 is connected to the connecting shaft 32 through a coupling.
[0046] At the same time, an elastic vibrating rod 351 is fixedly connected to the inner side wall of the rotating seat 33, and an elastic vibrating ball 35 is fixedly connected to the inner end of the elastic vibrating rod 351; the elastic vibrating rod 351 and the elastic vibrating ball 35 are made of rubber material. Utilizing the excellent elastic properties of the rubber material, during the working process, driven by the rotating motor 31, the elastic vibrating rod 351 - elastic vibrating ball 35 rotates clockwise and counterclockwise repeatedly and knocks on the bottom position of the blanking and sorting hopper 1, so as to vibrate the highly viscous concrete from the bottom of the blanking and sorting hopper 1 under the auxiliary knocking vibration to assist its blanking.
[0047] In this way, since the rotating motor 31 drives the elastic vibrating rod 351 - elastic vibrating ball 35 to vibrate and knock repeatedly without interruption during the blanking process, no matter how viscous the concrete is, it can be quickly blanked in this way, maintaining continuous blanking and discharging with very high smoothness. Thus, the blanking efficiency is improved.
[0048] The above-mentioned vibrating and feeding mechanism 3 further includes an annular frame 2 fixedly connected to the lower position of the cylindrical part. A plurality of connecting plates 311 are respectively installed on the top and bottom of the annular frame 2, and the rotating motor 31 is fixedly assembled between the connecting plates 311.
[0049] To improve the flexibility and stability of the rotation of the connecting shaft 32, a connecting shaft 32 is fixedly connected to the above-mentioned rotating seat 33 (the connecting shaft 32 penetrates through the rotating seat 33), and an internal convex seat 321 for rotatably connecting the connecting shaft 32 is welded on the inner side wall of the annular frame 2 (the outer end part of the connecting shaft 32 is rotatably connected in the same way as the existing method, and a suitable bearing is installed on the internal convex seat 321).
[0050] During the rotation process, the connecting shaft 32 is rotatably connected to the internal convex seat 321 in a supported manner.
[0051] At the same time, a plurality of L-shaped hanging plates 21 are fixedly connected to the top of the annular frame 2, and the L-shaped hanging plates 21 are fastened to the lower end position of the outer side wall of the cylindrical part by bolts. In this way, the annular frame 2 is fixed.
[0052] Embodiment 2
[0053] As Figures 1-5 shown, on the basis of the structure of Embodiment 1 in this embodiment, a reinforcing spring 34 is sleeved on the above-mentioned elastic vibrating rod 351, and the inner and outer ends of the reinforcing spring 34 are respectively fixedly connected to the rotating seat 33 and the elastic vibrating ball 35.
[0054] By sleeving the reinforcing spring 34, the elastic impact force of the elastic vibrating rod 351 and the elastic vibrating ball 35 is improved. Specifically, when the elastic vibrating rod 351 and the elastic vibrating ball 35 hit the bottom of the conical part, at this time, the elastic vibrating rod 351 deforms and bends, and the sleeved reinforcing spring 34 deforms and bends synchronously. In this way, the elastic force is increased. Under the elastic restoring force of the reinforcing spring 34 and the elastic vibrating rod 351 made of elastic material, the reset reinforcing spring 34 and the elastic vibrating rod 351 carry the elastic vibrating ball 35 and hit the bottom of the conical part forcefully, realizing the improvement of the effect of discharging concrete downward.
[0055] Embodiment 3
[0056] As Figures 1-5 shown, on the basis of the structure of Embodiment 2 in this embodiment, a discharge pipe 13 is integrally formed at the bottom of the above-mentioned conical part, and the discharge pipe 13 is communicated with a long discharge pipe 4. The discharge pipe 13 and the long discharge pipe 4 are communicated through a spring pipe assembly. The spring pipe assembly includes a spring pipe 41, and both ends of the spring pipe 41 are respectively communicated with the discharge pipe 13 and the long discharge pipe 4 through flanges.
[0057] Specifically, the bourdon tube 41 is a conventional bourdon tube 41 disclosed in the prior art, aiming to facilitate the adjustment of the angle, so that the long discharge pipe 4 for facilitating the blanking can discharge concrete at any angle.
[0058] Since the concrete obtains a certain kinetic energy after being impacted during the process of passing through the hopper, it can maintain smooth flow during the process of passing through the long discharge pipe 4.
[0059] Certainly, the above description is not a limitation to the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present invention should also fall within the protection scope of the present invention.
