Description

Technical Field

[0001] The utility model relates to the technical field of floor paving, and particularly relates to a reinforced paving and blanking device. Background Technique

[0002] During the floor construction process, the blanking of the slurry is a key technology. For example, since the slurry has a setting time and a certain viscosity, it is often necessary to level the slurry while blanking to quickly complete the blanking of the slurry and prevent the slurry from coagulating and solidifying. Of course, for slurries with low viscosity that can self-level, the leveling process can be reduced or even omitted. However, the problem of uneven slurry blanking still plagues the development of the technology. If manual pouring is carried out by workers, although the blanking position and blanking volume can be flexibly configured, it is difficult to make the blanking volume at each position uniform manually, which will lead to uneven floor paving. Moreover, the manual blanking method depends on the experience of workers, which not only has a large labor intensity but also is not conducive to large-area and long-time operations.

[0003] The Chinese utility model patent discloses CN220080675U, a floor paving device with the patent number 202321549241.2. The technical solution adopted is as follows: The lower part of a storage frame is fixedly connected with a blanking hopper. The front and rear side walls of the blanking hopper incline towards the middle to form a cone. A rectangular discharge port is opened at the lower end of the blanking hopper. Rectangular openings are symmetrically opened on the front and rear inclined side walls of the upper part of the rectangular discharge port. Baffles are movably inserted into the front and rear rectangular openings. The left and right side walls of the storage frame are respectively threadedly connected with support plates. The outer side walls of the lower ends of the support plates are rotatably installed with runners. The middle part of the rear side wall of the baffle is fixedly connected with the output shaft of an electric telescopic rod. The rear part of the body of the electric telescopic rod is fixedly connected with the middle side wall of a U-shaped fixing frame. The front end parts of the left and right side walls of the U-shaped fixing frame are respectively threadedly connected with the lower ends of the left and right side walls of the blanking hopper. A paving mechanism is fixedly installed at the lower part of the opposite sides of the left and right support plates.

[0004] However, it can be seen from the above-mentioned prior art patent that the moving direction of the baffle is basically perpendicular to the flowing direction of the slurry, which will cause the slurry to accumulate on the baffle and its driving mechanism, affecting the blanking accuracy. Moreover, when the baffle closes the discharge port, due to the accumulation of the slurry, there is still some slurry leaking out, making it difficult to accurately control the blanking volume, and the uniformity is also relatively ordinary. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a reinforced paving and blanking device that can accurately control the blanking volume and prevent material accumulation.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] An enhanced paving and blanking device, comprising a blanking bin, a blanking blocking plate and a pressing plate mechanism. The blanking bin has two mutually inclined first side plates and second side plates. The bottom of the first side plate extends beyond the bottom of the second side plate to form an extension part. A narrow and long discharge port is formed at an interval between the extension part and the bottom of the second side plate. The blanking blocking plate is slidably matched with the second side plate and switches between a position where it abuts against the extension part to block the discharge port and a position where it is away from the extension part to open the discharge port. The pressing plate mechanism is used to drive the blanking blocking plate to keep closely attached to the second side plate as a whole.

[0008] Preferably, the blanking blocking plate includes a plate body and reinforcing ribs distributed on the plate body. One side of the plate body is slidably matched with the outer side of the second side plate, and the reinforcing ribs are arranged on the other side of the plate body.

[0009] Preferably, the pressing plate mechanism includes a pressing wheel and a bracket. The bracket is fixed to the blanking bin, the pressing wheel is rotatably installed on the bracket, and the pressing wheel is in rolling cooperation with the blanking blocking plate and provides a pressing force for pressing the blanking blocking plate against the second side plate.

[0010] Preferably, the bracket includes two legs and a connecting plate. The two legs are fixedly connected to both sides of the connecting plate. Avoidance grooves for avoiding the legs are formed on the blanking blocking plate, and the two legs pass through the avoidance grooves and are fixed to the second side plate.

[0011] Preferably, an installation space is formed by enclosing the two legs and the connecting plate. The pressing wheel is located in the installation space and is connected to the two legs through a pivot shaft.

[0012] Preferably, adjustment grooves for the pivot shaft to pass through are provided on the two legs. The adjustment grooves are slidably matched with the pivot shaft, and the extending direction of the adjustment grooves is perpendicular to the blanking blocking plate.

[0013] Preferably, there are multiple pressing plate mechanisms, which are distributed at intervals along the length direction of the discharge port on the blanking blocking plate.

[0014] Preferably, both ends of the blanking bin have end plates, and the two ends are respectively sealed at the two ends of the first side plate and the second side plate. Buckle plates parallel to the blanking blocking plate extend from the end plates. An insertion opening is formed at an interval between the buckle plates and the first side plate. The two ends of the blanking blocking plate are respectively slidably inserted into the insertion openings.

[0015] Preferably, the enhanced paving and blanking device further includes a power mechanism. The power mechanism is fixedly installed on the second side plate, and the output end of the power mechanism has a linear motion and is fixedly connected to the blanking blocking plate.

[0016] Preferably, scraping plates are also vertically slidably installed on both side parts of the blanking bin. The bottom edge of the scraping plate is lower than the discharge port, and a diversion plate is obliquely arranged at the front end of the scraping plate. The two diversion plates at least partially block the front end of the blanking bin.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The enhanced paving and blanking device of the present utility model presses the blanking plate tightly against the second side plate through the pressing plate mechanism. At the same time, the blanking plate is slidably matched with the second side plate, so the moving direction of the blanking plate will be parallel to the second side plate. In this way, since the second side plate and the first side plate are inclined to each other, the blanking plate will cut into and out of the discharge port at an angle other than 90°, which is conducive to the smooth cutting into and out of the discharge port by the blanking plate, preventing the slurry from accumulating in the gap between the blanking plate and the second side plate during the blanking process at the discharge port. After blocking the discharge port, the slurry can be cut off in time without leakage. Moreover, when the blanking plate is opened, due to little or no accumulated material, the slurry can also fall and spread more evenly at various parts of the discharge port synchronously. It is especially applicable to slurries with high viscosity. The slurry can fall synchronously more slowly, and the blanking amount can be controlled uniformly at a constant speed, making the paving accuracy higher and the paving effect of the floor more uniform and flat.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.

[0025] As Figures 1-4An enhanced paving and blanking device shown in the figure includes a blanking bin 1, a blanking blocking plate 2 and a pressing plate mechanism 3. The blanking bin 1 has two mutually inclined first side plates 11 and second side plates 12. The bottom of the first side plate 11 extends beyond the bottom of the second side plate 12 to form an extension 13. A narrow and long material outlet 14 is formed at an interval between the extension 13 and the bottom of the second side plate 12. The blanking blocking plate 2 is slidably matched with the second side plate 12 and slides between a position where it abuts against the extension 13 to block the material outlet 14 and a position where it is away from the extension 13 to open the material outlet 14. The pressing plate mechanism 3 is used to drive the blanking blocking plate 2 to keep closely attached to the second side plate 12 as a whole.

[0026] By pressing the blanking blocking plate 2 tightly against the second side plate 12 through the pressing plate mechanism 3, and at the same time, the blanking blocking plate 2 is slidably matched with the second side plate 12, the moving direction of the blanking blocking plate 2 will be parallel to the second side plate 12. Thus, since the second side plate 12 and the first side plate 11 are mutually inclined, the blanking blocking plate 2 will cut into and out of the material outlet 14 at a non-90° angle, which is beneficial for the blanking blocking plate 2 to smoothly cut into and out of the material outlet 14, block the slurry during the blanking process at the material outlet 14, prevent the slurry from accumulating in the blanking blocking plate 2 and the gap between the blanking blocking plate 2 and the second side plate 12. After blocking the material outlet 14, the slurry can be cut off in time without leakage. And when the blanking blocking plate 2 is opened, since there is little or no accumulated material, the slurry can also fall and be paved more evenly and synchronously at each part of the material outlet 14, especially applicable to slurries with higher viscosity. The slurry can fall synchronously more slowly, the blanking amount can be controlled at a constant speed, the paving accuracy is higher, and the paving effect of the floor is more uniform and flat.

[0027] Among them, the slurry prepared for paving after stirring is stored in the blanking bin 1. It can be directly stirred in the blanking bin 1 or sent to the blanking bin 1 after stirring at other positions. In this embodiment, the first side plate 11 and the second side plate 12 are arranged mutually inclined, so that the blanking bin 1 forms a funnel shape. Combined with the narrow and long material outlet 14, the slurry can automatically fall at each place of the material outlet 14. Preferably, the included angle between the first side plate 11 and the second side plate 12 is an acute angle. Thus, the sliding direction of the blanking blocking plate 2 will be closer to the vertical, that is, closer to parallel to the slurry discharging direction of the material outlet 14, so as to reduce the impact on the slurry when blocking the material outlet 14 and avoid slurry splashing.

[0028] As Figure 1 、 Figure 2 、 Figure 4 As shown in the figure, the enhanced paving and blanking device of this embodiment further includes a power mechanism 4. The power mechanism 4 is fixedly installed on the second side plate 12. The power mechanism has an output end with linear motion, and this output end is fixedly connected to the blanking blocking plate 2. In this example, the power mechanism 4 is a hydraulic cylinder, and the output end is the output push rod of the hydraulic cylinder. Other power sources such as air cylinders and linear motors can also be used.

[0029] As Figure 2 、3 As shown, in one embodiment, the material blocking plate 2 includes a plate body 21 and reinforcing ribs 22 distributed on the plate body 21. One side of the plate body 21 is in sliding fit with the outer side of the second side plate 12, and the reinforcing ribs 22 are arranged on the other side of the plate body 21. In this way, the material blocking plate 2 can not only be kept in contact with the second side plate 12 to avoid the entry of slurry through the gap and maintain the smoothness of opening and closing the discharge port 14, but also have its strength enhanced by the reinforcing ribs 22 to prevent deformation and generate a gap with the second side plate 12, further improving the effect of preventing material accumulation. The arrangement of the reinforcing ribs 22 is arranged according to the needs of the plate material, thickness, etc. In this embodiment, the reinforcing ribs 22 are distributed at intervals in a rectangular shape.

[0030] As Figure 2 、 3 As shown, in a preferred embodiment, the pressing plate mechanism 3 includes a pressing wheel 31 and a bracket 32. The bracket 32 is fixed to the blanking bin 1, the pressing wheel 31 is rotatably installed on the bracket 32, and the pressing wheel 31 is in rolling fit with the material blocking plate 2 and provides a pressing force for pressing the material blocking plate 2 against the second side plate 12. By the way of pressing the material blocking plate 2 with the pressing wheel 31, on the basis of being able to adapt to the movement of the material blocking plate 2, the pressing pre-tightening force on the material blocking plate 2 can be maintained at the same time to enhance the blocking ability, and it can further prevent a gap from being generated between the material blocking plate 2 and the second side plate 12 to cause material accumulation.

[0031] Specifically, in this example, as Figure 3 shown, to enable the pressing plate mechanism 3 to press the material blocking plate 2 more stably, the bracket 32 includes two legs 321 and a connecting plate 322. The two legs 321 are fixedly connected to both sides of the connecting plate 322. An avoidance groove 23 for avoiding the legs 321 is formed on the material blocking plate 2. The two legs 321 pass through the avoidance groove 23 and are fixed to the second side plate 12. In this way, the avoidance groove 23 avoids the legs 321, the legs 321 can be fixed to the second side plate 12, and the avoidance groove 23 can be used as a positioning groove to limit the movement stroke of the material blocking plate 2. In this embodiment, an installation space is formed by enclosing the two legs 321 and the connecting plate 322, and the pressing wheel 31 is located in the installation space and is connected to the two legs 321 through a pivot 323 to minimize the volume and increase the strength.

[0032] Furthermore, to enhance the adjustment ability, adapt to different thicknesses of the material blocking plate 2, and be able to adjust the pressing pre-tightening force after long-term use, as Figure 3 shown, adjustment grooves 324 for the pivot 323 to pass through are provided on the two legs 321 of this embodiment. The adjustment grooves 324 are in sliding fit with the pivot 323, and the extending direction of the adjustment grooves 324 is perpendicular to the material blocking plate 2. In this way, a spring can be added and arranged between the bracket 32 and the pressing wheel 31, so that the pressing wheel 31 can always keep pressing the material blocking plate 2 and can adapt to the undulation of the material blocking plate 2 to facilitate the stable and smooth sliding of the material blocking plate 2.

[0033] AsFigure 2 As shown in the figure, in order to make the acting force of the blanking plate 2 on the second side plate 12 more uniform, there are multiple pressing plate mechanisms 3 in this embodiment, which are distributed at intervals along the length direction of the discharge port 14 on the blanking plate 2. On the one hand, it is beneficial to apply force evenly, and on the other hand, it can also press the blanking plate 2 at a larger part, reducing the probability of partial deformation of the blanking plate 2.

[0034] To further increase the stability and smoothness of the blanking plate 2 for opening and closing the discharge port 14, as Figure 1 、 3 shown, both ends of the blanking bin 1 in this embodiment have end plates 15, and the two ends are respectively sealed at the two ends of the first side plate 11 and the second side plate 12. A clamping plate 16 parallel to the blanking plate 2 extends from the end plate 15. An insertion slot 17 is formed between the clamping plate 16 and the first side plate 11. Both ends of the blanking plate 2 are respectively slidably inserted into the insertion slot 17. By restricting the blanking plate 2 in the normal direction through the clamping plate 16 and limiting it at the end of the blanking plate 2, the blanking plate 2 can maintain a smooth and precise sliding fit relative to the second side plate 12, which is more conducive to preventing material accumulation.

[0035] As Figure 1 、 2 shown in Fig. 4, in order to improve the uniformity effect after floor construction, scraping plates 5 are also vertically slidably installed on both sides of the blanking bin 1, so that the height of the scraping plates 5 in the vertical direction is adjustable to adapt to different scraping requirements. The bottom edge of the scraping plate 5 is lower than the discharge port 14, and an inclined diversion plate 51 extends from the front end of the scraping plate 5. The two diversion plates 51 at least partially block the front end of the blanking bin 1. The diversion plate 51 can partially guide the slurry scraped by the scraping plate 5 back to the front end of the blanking bin 1, so as to achieve a dynamic balance between the un-scraped side and the scraped side on the floor, and achieve a smoother and more efficient scraping effect.

[0036] The implementation manners of the present utility model are not limited thereto. According to the above-mentioned embodiment content of the present utility model, using the conventional technical knowledge and customary means in the art, without departing from the above basic technical idea of the present utility model and without conflict, the above preferred embodiments can also be modified, replaced or combined in other various forms. All other obtained embodiments fall within the scope of the protection of the rights of the present utility model.
