Description

Technical Field

[0001] The invention relates to the technical field of concrete processing, and in particular to automatic filling equipment for forming concrete test blocks. Background Art

[0002] Concrete test blocks, also known as cubic test blocks, are used to demonstrate the overall construction quality of concrete structures. Concrete test blocks are mainly used to test the compressive strength of concrete. Concrete test blocks produced in my country are generally made of cubic test blocks. Due to the large volume of 20 cubic centimeters of test blocks, it is easy to waste a lot of materials. Usually, 15 cubic centimeters of test blocks are used to make concrete test blocks.

[0003] In the prior art, there are two main forms of making concrete test blocks at home and abroad. One is manual manufacturing. This method is basically manual operation. Use a shovel to take out the concrete from the tanker and put it into a test mold little by little. Each test mold is filled with 1 / 3 of the entire space, and then use an iron rod to properly knock it down to make the material flat. Repeat this cycle until completion. This production method has high labor intensity and low production efficiency. At present, some problems often occur during the construction process. For example, due to the limitations of on-site conditions, it is impossible to transport all test blocks back to the construction site intact and safely. In addition, the production process is not standardized, resulting in concrete test blocks with missing edges and corners, rough surfaces, and serious bulging. In addition, defects such as poor verticality, diamonds, and pores may occur during transportation. In addition, there is no unified test block number, and some are even white test blocks without any identification. These have seriously affected the quality of concrete and reduced the quality of concrete. The other is automatic production and filling of large equipment. This form has huge cost investment and is not suitable for small and medium-sized enterprises. These directly affect the pouring construction and the development of later maintenance work. In addition, safety accidents are prone to occur on site. Based on the above problems, a new concrete test block filling equipment is needed to deal with them. Summary of the invention

[0035] In the present embodiment, an automatic filling device for forming concrete test blocks is disclosed. When working, firstly, the mixed concrete is prepared, and then the concrete is poured into the receiving cavity 10. Under the restriction of the first scraper 7, the second scraper 8 and the side wall of the receiving platform 5, the concrete is accumulated in the receiving cavity 10, and leaks into each forming cavity 3 of the filling mold 2 from the filling opening 9 of the receiving platform 5. Since the concrete is poured directly, only part of the concrete material enters the forming cavity 3. At this time, the driving unit 6 drives the first scraper 7 to move, and scrapes the concrete on the receiving platform 5 that has not fallen into the forming cavity 3 into the forming cavity 3 to fill the scraping material. When the first scraper 7 completes the one-way scraping, the driving unit 6 drives the first scraper 7 to move. The unit 6 drives the first scraper 7 and the second scraper 8 to move in the opposite direction to fill and scrape the material again. The first scraper 7 and the second scraper 8 move in the same direction. When the scraping is completed, the lifting unit 4 drives the material receiving platform 5 to rise.

[0037] In this embodiment, the driving unit 6 that drives the first scraper 7 and the second scraper 8 is specifically a rotating driving member 11 installed on the material receiving platform 5. The rotating driving member 11 can be a rotating driving unit such as a servo motor. The output end of the rotating driving member 11 is connected to the driving wheel 12 to drive the driving wheel 12 to rotate. A driven wheel 13 is also provided corresponding to the driving wheel 12. The driven wheel 13 is rotatably arranged on the material receiving platform 5. The driving chain 14 is sleeved on the driving wheel 12 and the driven wheel 13. The driving chain 14 is used to drive the slider rocker assembly 15 to move, wherein the slider rocker assembly 15 is arranged on the first scraper 7, so the rotation of the driving chain 14 can drive the first scraper 7 to move. At the same time, the slider rocker mechanism will change the positional relationship of the internal components of the slider rocker mechanism during the process of following the rotation of the driving chain 14. When the driving chain 14 drives the first scraper 7 to complete the scraping stroke, the slider rocker mechanism also changes the positional relationship of the internal components and cooperates with the second scraper 8. The driving chain 14 continues to run, which will drive the first scraper 7 and the second scraper 8 to move and scrape at the same time.

[0038] The slider rocker assembly 15 includes a slide 16, a sliding block 17, a first connecting rod 18 and a second connecting rod 19. The slide 16 is detachably arranged on the first scraper 7.

The second connecting rod 19 is provided with a first abutting end 20 and a second abutting end 21. The sliding block 17 moves along the slide 16 to drive the second connecting rod 19 to swing around its hinge point. The first abutting end 20 and the second abutting end 21 selectively abut against the second scraper 8.

[0039] In this embodiment, the slider rocker assembly 15 specifically comprises a slideway 16 on the first scraper 7, and a sliding block 17 is fixedly arranged on the driving chain 14. The sliding block 17 can move along the length direction of the slideway 16 in the slideway 16. When the sliding block 17 moves, it will drive the first connecting rod 18 to swing. When the first connecting rod 18 swings, it will drive the second connecting rod 19 to move. The second connecting rod 19 is hinged to the slideway 16. Under the action of the first connecting rod 18, the second connecting rod 19 swings around its hinge point on the slideway 16 to achieve position adjustment. The second connecting rod 19 is provided with a first abutting end 20 and a second abutting end 21. The movement of the sliding block 17 can selectively make the first abutting end 20 abut against the second scraper 8 or the second abutting end 21 abut against the second scraper 8, thereby achieving selective movement of the second scraper 8.

[0040] In a conceivable embodiment, the second connecting rod 19 can be designed as a combination of two L-shaped parts, one of the L-shaped parts serves as the main body, one end of which is hinged to the second connecting rod 19, and the other end is hinged to the slide 16, and the other L-shaped part is installed on the L-shaped part serving as the main body. The two L-shaped parts are installed at a certain angle. When the drive chain 14 moves to the initial position of the second scraper 8, the sliding block 17 moves in the slide 16, driving the first connecting rod 18 to swing, and pushing the L-shaped part serving as the main body to a horizontal state, and the L-shaped part serving as the main body hangs the second scraper 8 on the inside, and as the drive chain 14 runs, the second scraper 8 follows it; when the drive chain 14 reaches the extreme position at the other end, the sliding block 17 adjusts its position again. At this time, the L-shaped part installed as an accessory adjusts its position, the drive chain 14 continues to run, and the L-shaped part serving as an accessory pushes the second scraper 8 to move to achieve scraping.

[0041] It should be noted that the specific structure of the second connecting rod 19 is only one of the possible embodiments, and other structures can also be designed to enable the driving unit 6 to selectively drive the second scraper 8, thereby achieving automatic scraping of concrete and improving production efficiency.

[0042] The first scraper boss 22 and the second scraper boss 23 are arranged on the opposite sides of the first scraper 7 and the second scraper 8, wherein the first scraper boss 22 is arranged below the second scraper boss 23 and the first scraper boss 22 is located at the bottom side of the first scraper 7 and the second scraper 8, and the second scraper boss 23 is provided with an inclined surface 24 on the side close to the first scraper boss 22, and the inclined surface 24 is inclined upward along the forward direction.

At the same time, the first scraper boss 22 can improve the scraping rate and scrape the concrete as cleanly as possible. As the scraping increases, the concrete begins to accumulate under the second scraper boss 23. The side of the second scraper boss 23 close to the first scraper boss 22 is an inclined surface 24, and the inclined direction extends upward along the direction of the scraping prospect. Therefore, in the process of pushing the scraper During the process, the second scraper boss 23 has a downward pressing force on the accumulated concrete material. When the first scraper 7 scrapes over the top of the molding cavity 3, the second scraper boss 23 presses the concrete so that it can enter the molding cavity 3 more tightly, avoiding the formed test block from having defects such as air holes and bulges. The first scraper boss 22 flattens the surface of the test block to improve the surface quality and ensure the size, verticality and flatness of the test block. After the first scraper 7 completes the scraping, the second scraper 8 scrapes again in the opposite direction. The first scraper boss 22 and the second scraper boss 23 on the second scraper 8 scrape, compact and flatten the concrete again, thereby improving the molding quality of the test block.

[0056] S200: Filling and scraping, the first scraper 7 moves to perform the first filling and scraping, and then the second scraper 8 and the first scraper 7 simultaneously perform the second filling and scraping;

[0057] S300: Vibration exhaust, the lifting unit 4 rises to separate the filling mold 2 from the material receiving platform 5, and the vibrating base 1 drives the filling mold 2 to vibrate to exhaust the concrete in the filling mold 2. After a certain period of vibration, the lifting unit 4 is lowered, and the material receiving platform 5 abuts against the filling mold 2;

[0058] S400: The receiving chamber 10 is restored, the second scraper 8 and the first scraper 7 move simultaneously, the second scraper 8 moves to the initial position, and then the first scraper 7 moves alone, and the first scraper 7 moves to the initial position;

[0060] S600: Refilling and scraping, the first scraper 7 moves to perform the first refilling and scraping, and then the second scraper 8 and the first scraper 7 simultaneously perform the second refilling and scraping;

[0061] S700: Unloading, first restore the receiving cavity 10, then raise the lifting unit 4 to separate the filling mold 2 from the receiving platform 5, unload the filling mold 2, and obtain the test block after the test block in the filling mold 2 is cured.

[0062] In this embodiment, based on the automatic filling equipment for forming concrete test blocks in the above embodiment, a method for automatic filling of concrete test blocks is proposed. First, the concrete is evenly mixed by a mixer, and then the automatic filling equipment is in a state of preparing to receive materials. At this time, the receiving platform 5 of the automatic filling equipment is in contact with the upper end of the filling mold 2, and the filling opening 9 of the receiving platform 5 corresponds to the forming cavity 3. The first scraper 7 and the second scraper 8 on the receiving platform 5 are separated on both sides to form a receiving cavity 10 with the side wall of the receiving platform 5, and then filling is performed. Concrete is poured into the receiving cavity 10, and part of the concrete will pass through the loading The filling opening 9 falls into the molding cavity 3, and then the filling and scraping are carried out. The driving unit 6 drives the first scraper 7 to perform the first filling and scraping, and at the same time, the concrete in the receiving cavity 10 is scraped into the molding cavity 3, and the concrete is compacted and the surface is smoothed. After the first scraper 7 finishes scraping, the driving unit 6 drives the second scraper 8 and the first scraper 7 to move the scraper in the opposite direction at the same time, so as to further fill, compact and smooth the surface; then the lifting unit 4 raises the receiving platform 5, and the receiving platform 5 is separated from the filling mold 2, and the vibration base 1 drives the filling mold 2 to vibrate, so that the concrete in the molding cavity 3 is uniform and exhausted. To avoid the generation of internal air holes, after the vibration ends, the lifting unit 4 is lowered again, and the receiving platform 5 is in contact with the filling mold 2 again, and the driving unit 6 drives the first scraper 7 and the second scraper 8 to move to the initial position. Specifically, the driving unit 6 drives the first scraper 7 and the second scraper 8 to move from the side of the driving wheel 12 to the side of the driven wheel 13. When the second scraper 8 returns to the initial position on the side of the driven wheel 13, the second connecting rod 19 is disengaged from the second scraper 8. At this time, the driving unit 6 is reversed, and the first scraper 7 alone is driven to return to the initial position on the side of the driving wheel 12, thereby restoring the receiving cavity 10. Then the concrete in the mixer is fed to the receiving chamber 10. The amount of the feed can be relatively small and can be adaptively controlled according to the actual amount. Then the driving unit 6 drives the first scraper 7 and the second scraper 8 again to feed and scrape the material to supplement the part of the concrete material missing in the molding chamber 3 after vibration. The first scraper 7 and the second hanging plate further compact and trim the test block after the feed to improve the molding quality of the test block. After the second scraping, the receiving chamber 10 is returned, the lifting unit 4 is raised, the filling mold 2 is separated from the receiving platform 5, and after the filling mold 2 is removed, the test block is obtained after curing according to the curing requirements.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
