Description

Technical Field

[0001] This application relates to the technical field of concrete equipment, and in particular to an anti-adhesion concrete raw material feed hopper. Background Technology

[0002] Concrete is a general term for materials that bind together to form a cohesive whole. Generally speaking, concrete refers to concrete made by mixing sand and gravel as aggregates with water in a specific ratio, using sand and gravel as the binder.

[0003] Currently, during concrete production, various raw materials are added to a mixer in proportion through a feed hopper. The mixer then mixes the cementitious materials, aggregates, and water to form concrete mortar, which facilitates subsequent concrete pouring.

[0004] However, as the feed hopper sequentially adds various raw materials into the mixer, these materials tend to adhere to the feed hopper. The interaction between the raw materials and the feed hopper, as well as between the various raw materials themselves, eventually forms a sticky block on the feed hopper, thus preventing the addition of subsequent raw materials. Utility Model Content

[0005] In order to reduce the probability of the formation of adhesive blocks on the concrete raw material feed hopper, this application provides an anti-adhesion concrete raw material feed hopper.

[0006] This application provides an anti-adhesion concrete raw material feed hopper, which adopts the following technical solution:

[0007] A non-adhesive concrete raw material feed hopper includes a frame, on which a feed hopper for concrete raw materials to enter a mixer is mounted. The frame also includes a cleaning mechanism for cleaning the feed hopper, the cleaning mechanism comprising:

[0008] A scraper is rotatably mounted on the inner side of the feed hopper via an installation assembly. When the scraper rotates, it scrapes the material from the inner side of the feed hopper.

[0009] A drive assembly, which is mounted on the frame and is used to drive the scraper to rotate.

[0010] By adopting the above technical solution, after the feed hopper guides the concrete raw materials, the drive component drives the scraper to rotate through the installation component, so that the scraper rotates and scrapes the material on the inner wall of the feed hopper, thereby scraping off the concrete raw materials on the inner wall of the feed hopper in a timely manner and reducing the probability of the formation of adhesive blocks on the concrete raw material feed hopper.

[0011] Furthermore, the installation components include:

[0012] A rotating ring is rotatably mounted on the feed hopper and connected to the drive assembly. An annular opening is provided on the inner side wall of the feed hopper.

[0013] The mounting block is disposed on the side of the rotating ring near the feed hopper, passing through the annular opening, and the scraper is disposed on the mounting block.

[0014] By adopting the above technical solution, the drive component drives the rotating ring to rotate, thereby driving the scraper installed on the mounting block to rotate, and finally achieving scraping treatment of the inner wall of the feed hopper.

[0015] Furthermore, the scraper includes:

[0016] The mounting bracket is bolted to the mounting block, and the mounting bracket has a mounting groove on the side near the inner wall of the feed hopper.

[0017] The scraper is snapped into the mounting groove, with one end away from the mounting groove abutting against the side wall of the feed hopper.

[0018] By adopting the above technical solution, the scraper is snapped into the mounting groove, and then the mounting bracket is fixed to the mounting block with bolts, so that the scraper is pressed against the inner wall of the feed hopper. When the scraper is damaged, it can be replaced, which reduces the replacement cost of the scraper.

[0019] Furthermore, the mounting frame is equipped with a buffer assembly for improving the contact effect between the scraper and the inner wall of the feed hopper, the buffer assembly comprising:

[0020] A retaining plate is slidably disposed at the bottom of the mounting groove along the sliding direction of the scraper, and the mounting groove is provided with a limiting groove to limit the maximum sliding distance of the retaining plate;

[0021] A compression spring is disposed at the bottom of the mounting groove and is used to push the abutment plate to slide away from the bottom of the mounting groove.

[0022] By adopting the above technical solution, the compression spring pushes the clamping plate to slide closer to the scraper. Through the cooperation of the compression spring and the clamping plate, the scraper is finally pressed against the inner wall of the feed hopper. At the same time, the scraper can still press against the inner wall of the feed hopper after it is worn, thus reducing the replacement frequency of the scraper.

[0023] Furthermore, the mounting bracket is provided with a mounting plate at the end away from the scraper to form the bottom of the mounting groove. The mounting plate is detachably mounted on the mounting bracket by bolts and facilitates the installation and removal of the clamping plate and the compression spring.

[0024] By adopting the above technical solution, when it is necessary to install the clamping plate and the compression spring, the mounting plate is taken out, then the clamping plate is slidably installed in the limiting groove, the compression spring is clamped and installed on the clamping plate, and finally the mounting plate is clamped on the end of the compression spring away from the clamping plate and locked with bolts.

[0025] Furthermore, a positioning post is provided at the end of the abutment plate near the compression spring, and the end of the compression spring near the abutment plate is sleeved on the positioning post. A positioning groove for positioning the compression spring is provided on the mounting plate.

[0026] By adopting the above technical solution, one end of the compression spring near the abutment plate is sleeved on the positioning post, and the other end of the compression spring is set in the positioning groove, thereby fixing both ends of the compression spring.

[0027] Furthermore, a baffle is provided on the rotating ring, and the baffle cooperates with the mounting block to rotate and seal the annular opening.

[0028] By adopting the above technical solution, the baffle rotates and seals the annular opening, reducing the probability of raw materials entering the annular opening. At the same time, when the rotating ring drives the scraper to scrape the material from the feed hopper, the baffle rotates and connects with the feed hopper, thus ensuring the sealing of the annular opening.

[0029] Furthermore, the frame is equipped with a nozzle for rinsing the scraper blades.

[0030] By adopting the above technical solution, since the raw material tends to adhere to the scraper after the scraper scrapes the inner wall of the feed hopper, the surface of the scraper is rinsed by the nozzle after the scraper finishes scraping the inner wall of the feed hopper. This reduces the probability of raw material adhering to the scraper and facilitates subsequent scraping of the inner wall of the feed hopper by the scraper.

[0031] Furthermore, the driving component includes:

[0032] A drive motor, which is mounted on the frame;

[0033] A conveyor belt is rotatably mounted on the frame and used to connect a drive motor and a rotating ring. The drive motor drives the rotating ring to rotate via the conveyor belt.

[0034] By adopting the above technical solution, the drive motor drives the conveyor belt to rotate, and the conveyor belt drives the rotating ring to rotate, so that the rotating ring rotates when the drive motor starts, and finally drives the scraper to rotate and scrape the material on the inner wall of the feed hopper.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. After the concrete raw materials are guided through the feeding hopper, the drive motor drives the rotating ring to rotate, which in turn drives the mounting frame to rotate. This causes the scraper on the mounting frame to rotate and scrape the material from the inner wall of the feeding hopper, thereby removing the concrete raw materials from the inner wall of the feeding hopper in a timely manner and reducing the probability of the formation of adhesive blocks on the concrete raw material feeding hopper.

[0037] 2. By compressing the spring, the clamping plate is pushed against the scraper, ultimately pressing the scraper against the inner wall of the feed hopper, thus improving the scraping effect of the scraper on the feed hopper. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0044] This application discloses an anti-adhesion concrete raw material feed hopper.

[0045] Reference Figure 1 A type of anti-adhesion concrete raw material feed hopper 2 includes a frame 1, on which a feed hopper 2 for concrete raw materials to enter a mixer is provided, and on which a cleaning mechanism 3 for cleaning the feed hopper 2 is provided.

[0046] Reference Figure 1The feed hopper 2 is fixedly installed on the frame 1. A discharge pipe connected to the inside of the mixer is fixedly installed on the bottom of the feed hopper 2. The top of the feed hopper 2 is conical and the diameter near the discharge pipe is smaller, so as to facilitate the collection of concrete raw materials. Then, the concrete is discharged directly into the mixer through the discharge pipe at the bottom of the feed hopper 2. The discharge pipe is usually a vertically installed straight pipe, which reduces the probability of adhesion inside the discharge pipe. However, the conical structure of the feed hopper 2 has a certain inclination angle on its inner side wall. When multiple concrete raw materials move on the feed hopper 2, some of the concrete raw materials mix with each other. After a long period of time, they eventually adhere to the inside of the feed hopper 2, thereby reducing the collection effect of the feed hopper 2 on the concrete raw materials.

[0047] Reference Figure 1 The cleaning mechanism 3 includes a scraper 4 and a drive assembly 6. The scraper 4 is mounted on the inner side of the feed hopper 2 via the mounting assembly 5. When the scraper 4 rotates, it scrapes the inner wall of the feed hopper 2 to remove the concrete material from the feed hopper 2 in a timely manner. The drive assembly 6 is mounted on the frame 1 and is used to drive the scraper 4 to rotate.

[0048] Reference Figure 1 and Figure 2 The mounting assembly 5 includes a rotating ring 51 and a mounting block 52. The rotating ring 51 is rotatably mounted on the outer wall of the feed hopper 2, and an annular opening 21 is provided on the inner wall of the feed hopper 2. The mounting block 52 passes through the annular opening 21 and is fixedly mounted on the side of the rotating ring 51 near the feed hopper 2. A scraper 4 is disposed on the mounting block 52. At the same time, a baffle 53 is fixedly mounted on the rotating ring 51. The baffle 53 is rotatably connected to the feed hopper 2. The baffle 53 and the mounting block 52 cooperate with each other to finally rotate and seal the annular opening 21. In this embodiment, a smooth layer is sprayed on the baffle 53. The smooth layer reduces the probability of raw materials accumulating on the baffle 53. At the same time, the baffle 53 rotates with the rotating ring 51, and it is also convenient to shake off the raw materials adhering to the baffle 53 during the rotation process.

[0049] Reference Figure 1 The drive assembly 6 includes a drive motor 61 and a transmission belt 62. The drive motor 61 is fixedly mounted on the frame 1. A drive wheel is fixedly mounted on the output shaft of the drive motor 61, and a driven wheel is fixedly mounted on the rotating ring 51. The transmission belt 62 is rotatably mounted on the frame 1. Both ends of the transmission belt 62 are connected to the drive wheel and the driven wheel respectively to realize the transmission between the drive wheel and the driven wheel, and finally realize that the drive motor 61 drives the rotating ring 51 to rotate.

[0050] Reference Figure 3 and Figure 4The scraper 4 includes a mounting frame 41 and a scraper blade 42. The mounting frame 41 is fixedly mounted on the mounting block 52 by bolts. The mounting frame 41 has a mounting groove 411 on the side of the mounting frame 41 closest to the inner wall of the feed hopper 2. The scraper blade 42 has a strip-shaped structure and is snapped into the mounting groove 411. The end of the scraper blade 42 away from the mounting groove 411 is pressed against the side wall of the feed hopper 2, so that the scraper blade 42 scrapes against the inner wall of the feed hopper 2, reducing the probability of the feed hopper 2 sticking. At the same time, when the scraper blade 42 is damaged, the scraping effect on the inner wall of the feed hopper 2 can be restored by replacing the scraper blade 42.

[0051] Reference Figure 3 and Figure 4 To improve the contact effect between the scraper 42 and the inner wall of the feed hopper 2, a buffer assembly 7 is provided on the mounting frame 41. The buffer assembly 7 is used to improve the contact effect between the scraper 42 and the inner wall of the feed hopper 2. The buffer assembly 7 includes a pressing plate 71 and a compression spring 72. The pressing plate 71 is slidably installed on the bottom of the mounting groove 411 along the sliding direction of the scraper 42. The mounting groove 411 is provided with a limiting groove 412 to limit the maximum sliding distance of the pressing plate 71. The compression spring 72 is provided on the bottom of the mounting groove 411. The compression spring 72 is used to push the pressing plate 71 to slide away from the bottom of the mounting groove 411, thereby improving the contact effect between the scraper 42 and the inner wall of the feed hopper 2. At the same time, when the scraper 42 is worn, the compression spring 72 ensures that the worn scraper 42 can still be pressed against the inner wall of the feed hopper 2.

[0052] Reference Figure 3 and Figure 4 The mounting bracket 41 has a mounting plate 8 at the end away from the scraper 42, which forms the bottom of the mounting groove 411. The mounting plate 8 is detachably mounted on the side of the mounting bracket 41 away from the scraper 42 by bolts. By removing the mounting plate 8, the clamping plate 71 and the compression spring 72 can be installed and removed. Multiple sets of positioning posts 711 are fixedly installed on the end of the clamping plate 71 near the compression spring 72. The multiple sets of positioning posts 711 are parallel to each other. The end of the compression spring 72 near the clamping plate 71 is sleeved on the positioning post 711. The positioning post 711 positions the compression spring 72, thereby reducing the probability of the compression spring 72 bending and deforming. The bottom of the mounting plate 8 has a positioning groove 81 for positioning the compression spring 72. The positioning groove 81 and the positioning post 711 fix both ends of the compression spring 72, thereby reducing the probability of the compression spring 72 failing.

[0053] Reference Figure 1 and Figure 2The frame 1 is fixedly equipped with a nozzle 9 for rinsing the scraper 42. After the scraper 42 scrapes the material on the inner wall of the feed hopper 2, the mounting block 52 moves the scraper 42 to the rinsing area and rinses the side wall of the scraper 42 through the nozzle 9, thereby reducing the probability of concrete material sticking to the scraper 42.

[0054] Reference Figures 1-4 Specifically, when the feeding hopper 2 completes the feeding of a type of concrete material or stops midway, the drive motor 61 starts, which drives the rotating ring 51 to rotate, thereby causing the scraper 42 to slide against the inner wall of the feeding hopper 2 to scrape the material off the inner wall of the feeding hopper 2. When the scraper 42 stops scraping, the nozzle 9 is started to wash the side of the scraper 42 near the inner wall of the feeding hopper 2. After the scraper 42 is cleaned, the feeding hopper 2 can be scraped repeatedly. The scraper 42 needs to be washed after each scraping.

[0055] The working principle of this application embodiment is as follows:

[0056] After the concrete raw materials are guided through the feed hopper 2, the drive motor 61 drives the rotating ring 51 to rotate. The rotating ring 51 drives the mounting frame 41 to rotate, which in turn causes the scraper 42 on the mounting frame 41 to rotate and scrape the material on the inner wall of the feed hopper 2. This removes the concrete raw materials on the inner wall of the feed hopper 2 in a timely manner, reducing the probability of the formation of adhesive blocks on the concrete raw material feed hopper 2.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
