Description

Technical Field

[0001] The utility model relates to the technical field of brick making equipment, in particular to a cylinder automatic scraping device when a material cart is retreated. Background Art

[0002] Brick making is the process of using stone powder, sand, slag, furnace slag and other materials as brick making materials and adding cement to make bricks. Brick making molds are needed to shape the bricks and complete the production of bricks.

[0003] When making bricks, the existing brick making machine needs to use a material cart to distribute the aggregate in the lower mold. When the material cart is distributing the aggregate, some of the aggregate will remain on the surface of the lower mold frame after being distributed. When the material cart comes in to distribute the aggregate, some of the aggregate will cross over the aggregate, affecting the appearance of the surface layer of the brick, thereby affecting the quality of the brick.

[0004] In order to solve this problem, the utility model is produced. Utility Model Content

[0005] Therefore, in view of the above problems, the utility model proposes a cylinder automatic scraping device which has a simple structure and is convenient for scraping off the excess material on the mold when the material cart returns.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is to provide a cylinder automatic scraping device when the material cart is retreated, including a material cart and a scraper that can interfere with the upper mold, and swing plates are provided at both ends of the scraper. The swing plates are rotatably arranged at both ends of the material cart, and a lifting device is provided on the material cart to drive the scraper to rise and fall.

[0007] A further improvement is that the lifting device comprises a cylinder, one end of the cylinder is hinged on the material cart, and the other end of the cylinder is hinged on the scraper.

[0008] A further improvement is that a plastic plate is provided on the scraper, and the plastic plate contacts the surface of the upper mold after descending.

[0009] A further improvement is that: a plurality of adjustment channels are provided on the plastic plate, and an adjustment bolt is locked between the plastic plate and the scraper, and the adjustment bolt is located in the adjustment channel.

[0010] A further improvement is that it also includes two limit plates, which are symmetrically arranged at the front end of the material car, and limit bolts are threadedly penetrated on the limit plates. When the scraper is lifted upward, it resists the limit bolts.

[0011] A further improvement is that: a plurality of L-shaped positioning rods are provided on the scraper at the other side of the plastic plate, and positioning bolts are provided on the positioning rods, and the positioning bolts resist the plastic plate.

[0012] Further improvement is that: a first connecting ear is provided on the material cart, a second connecting ear is provided on the scraper, and two ends of the air cylinder are respectively hinged to the first connecting ear and the second connecting ear.

[0013] Further improvement is that: a connecting plate is provided on the swing plate, and the connecting plate is connected to the scraper by bolts.

[0014] The advantages and beneficial effects of the present utility model are as follows:

[0015] The structure is simple and it is convenient to clean and recycle the remaining materials. When in use, when the material cart returns to its position, the plastic plate can scrape the remaining materials on the surface of the mold, so that the remaining materials fall into the lower mold or return with the material cart, ensuring the cleanliness of the surface of the lower mold, which is beneficial to brick making, ensuring the quality of the bricks produced, preventing the mixing of thick and differently colored aggregates, making the surface of the bricks beautiful, and not wasting materials, which is beneficial to green production. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a schematic structural diagram of the automatic scraping device of the air cylinder when the material cart returns in the embodiment of the present utility model.

[0017] Figure 2 It is a schematic enlarged structural diagram at position A in the embodiment of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following combines the drawings and embodiments to further describe the specific implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0019] As Figure 1 - Figure 2 shown, the automatic scraping device of the air cylinder when the material cart returns includes a material cart 1, a scraper 3 that can abut against the upper mold, and an air cylinder 5. Swing plates 2 are provided at both ends of the scraper 3. The swing plates 2 are rotatably provided at both ends of the material cart 1. One end of the air cylinder 5 is hinged to the material cart 1, and the other end of the air cylinder 5 is hinged to the scraper 3.

[0020] In order to prevent abrasion of the surface of the upper mold, a plastic plate 4 is provided on the scraper 3, and after the plastic plate 4 descends, it abuts against the surface of the upper mold.

[0021] When in use, when the material cart 1 is to spread the material, the cylinder 5 returns to its position, lifts the scraper 3, and then the material cart 1 spreads the material. When the spreading is completed, the cylinder 5 works, and the extension rod of the cylinder 5 extends, so that the plastic plate 4 is downwardly opposed to the surface of the upper mold, and then as the material cart 1 returns to its position, the plastic plate 4 scrapes off the remaining material on the surface of the mold, so that the remaining material falls into the lower mold, or as the material cart 1 returns to its position, the surface of the lower mold is ensured to be clean, which is conducive to the brick making process and the quality of the bricks, and there will be no forked and coarse aggregates of different colors, so that the surface of the bricks is beautiful, and there will be no waste of materials, which is conducive to green production.

[0022] In order to facilitate the adjustment of the plastic plate 4 so that the plastic plate 4 can match materials of different sizes for scraping, three adjustment channels 8 are opened on the plastic plate 4, and an adjustment bolt is locked between the plastic plate 4 and the scraper 3, and the adjustment bolt is located in the adjustment channel 8. Among them, when the material particles are large or the leakage is more, the plastic plate 4 extends downward from the scraper 3 more, so that the material can be scraped better. When the material particles are small or the leakage is less, the plastic plate 4 extends downward from the scraper 3 less, so that different materials can be scraped and cleaned better.

[0023] In order to facilitate the lifting of the scraper 3, two limit plates 6 are also included. The limit plates 6 are symmetrically arranged at the front end of the material car 1. The limit plates 6 are threaded with limit bolts 7. When the scraper 3 is lifted upward, it resists the limit bolts 7.

[0024] In order to keep the scraper 3 in a horizontal state when adjusting and prevent the plastic plate 4 from having a height difference, a plurality of L-shaped positioning rods 9 are provided on the scraper 3 on the other side of the plastic plate 4. The positioning rods 9 are provided with positioning bolts 10, and the positioning bolts 10 resist the plastic plate 4.

[0025] In order to facilitate the installation and connection of the cylinder 5, a first connecting ear 11 is provided on the material cart 1, a second connecting ear is provided on the scraper 3, the cylinder 5 is hinged on the first connecting ear 11, and the extension rod of the cylinder 5 is hinged on the second connecting ear.

[0026] In order to facilitate the connection between the swing plate 2 and the scraper plate 3, a connecting plate is provided on the swing plate 2, and the connecting plate is connected to the scraper plate 3 by bolts.

[0027] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments.
