Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of concrete mixing devices, and in particular to a concrete mixing device. Background Technology
[0002] Concrete is the most widely used man-made civil engineering material in the world. The production process of concrete requires mixing and stirring various substances. A concrete mixer is a machine that mixes and stirs cement, sand and gravel aggregates and water to make concrete mixture.
[0003] Under current technological conditions, during concrete mixing, materials are typically added to the mixing drum in sequence with water. As the mixing blades rotate, some materials adhere to the inner wall of the drum, preventing them from being fully mixed. When the concrete is discharged, the material adhering to the drum wall cannot be easily removed, thus reducing production efficiency and increasing the difficulty for workers to clean the mixing drum. Utility Model Content
[0004] The main purpose of this invention is to provide a concrete mixing device that improves the mixing effect of concrete materials and reduces residues on the inner wall of the mixing drum, thereby reducing the difficulty of subsequent cleaning.
[0005] To achieve the above objectives, this utility model proposes a concrete mixing device, comprising:
[0006] A mixing tank, on which a cover is snapped, and a servo motor is fixedly connected to the cover;
[0007] A stirring column, which is rotatably connected to the cover, and a stirring blade is fixedly connected to the lower end of the stirring column;
[0008] A discharge plate, which is slidably connected to the lower side of the mixing tank;
[0009] A scraping assembly, used to scrape material from the inner wall of the mixing tank as the stirring blades rotate, the scraping assembly being disposed inside the mixing tank, and comprising:
[0010] A transmission plate, which is fixedly connected to a stirring column, and a transmission column is rotatably connected to the transmission plate;
[0011] A receiving plate, which is rotatably connected to the transmission column;
[0012] A positioning plate, which is fixedly connected to a receiving plate;
[0013] The material ejector bar is engaged with the positioning plate and abuts tightly against the wall of the mixing tank.
[0014] In one possible implementation, the positioning plate has a first positioning groove, and the ejector bar has a second positioning groove.
[0015] In one possible implementation, a scraper is fixedly connected to the lower end of the positioning plate, and the scraper is in close contact with the wall of the mixing tank.
[0016] In one possible implementation, a transmission gear is fixedly connected to the upper end of the transmission column, and a transmission gear ring is fixedly connected to the lower side of the cover, wherein the transmission gear meshes with the transmission gear ring.
[0017] In one possible implementation, a sealing plate is fixedly connected to the lower side of the cover.
[0018] In one possible implementation, a plurality of stirring hammers are fixedly connected to the stirring blade.
[0019] This utility model's technical solution utilizes the cooperation between the scraping component and the transmission plate. The transmission plate's driving action enables the scraping bar to perform scraping operations synchronously with the rotation of the mixing column. The scraping bar continuously compresses the material adhering to the inner wall of the mixing drum, effectively reducing material adhesion to the drum wall and allowing for more uniform mixing. This continuous scraping action significantly improves the mixing effect. Furthermore, when the material mixing is complete and discharge is required, after most of the concrete material has been poured out, the scraping bar will press downwards on the remaining material adhering to the inner wall, allowing the material in the mixing drum to be fully discharged, reducing the adhesion of concrete material to the drum wall, and minimizing residue on the inner wall of the mixing drum, thus reducing the difficulty of subsequent cleaning.

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Example
[0029] Reference Figures 1 to 4 This utility model proposes a concrete mixing device, comprising:
[0030] A mixing tank 11, a cover 12 is snapped onto the mixing tank 11, and a servo motor 13 is fixedly connected to the cover 12;
[0031] A stirring column 14 is rotatably connected to a cover 12, and a stirring blade 15 is fixedly connected to the lower end of the stirring column 14.
[0032] Discharge plate 16 is slidably connected to the lower side of mixing tank 11;
[0033] Users can control the amount of concrete discharged from the mixing drum 11 by opening and closing the discharge plate 16 and adjusting its sliding distance, which makes it convenient for workers to operate.
[0034] The scraping assembly is used to scrape the material from the inner wall of the mixing tank 11 as the mixing blade 15 rotates. The scraping assembly is installed inside the mixing tank 11.
[0035] Through the cooperation of the scraping component and the transmission plate 21, the scraping bar 25 can perform scraping operations synchronously with the rotation of the mixing column 14 by the driving action of the transmission plate 21. The function of the scraping bar 25 is to continuously squeeze the material adhering to the inner wall of the mixing drum 11, thereby effectively reducing the material adhering to the drum wall and making the material more uniformly mixed. Through this continuous scraping action, the mixing effect is significantly improved. In addition, when the material is mixed and needs to be discharged, when most of the concrete material has been poured out, the scraping bar 25 will squeeze the remaining material adhering to the inner wall downwards, so that the material in the mixing drum 11 can be fully poured out, reducing the adhesion of concrete material to the drum wall of the mixing drum 11, reducing the residue on the inner wall of the mixing drum 11, and thus reducing the difficulty of subsequent cleaning.
[0036] Reference Figures 2 to 3 The rejection assembly includes:
[0037] Transmission plate 21 is fixedly connected to stirring column 14, and transmission column 22 is rotatably connected to transmission plate 21.
[0038] The receiving plate 23 is rotatably connected to the transmission column 22;
[0039] Positioning plate 24, which is fixedly connected to receiving plate 23;
[0040] The material ejector bar 25 is engaged with the positioning plate 24 and is in close contact with the wall of the mixing tank 11.
[0041] The scraping assembly, driven by the transmission plate 21, carries the scraping strip 25 to perform a synchronous scraping operation on the inner wall of the mixing tank 11 as the mixing column 14 rotates. This causes the material adhering to the inner wall of the mixing tank 11 to be continuously squeezed, allowing the material to mix better and improving the mixing effect. At the same time, when the mixed material needs to be transported out, the scraping strip 25 can also squeeze the material adhering to the inner wall of the mixing tank 11 downwards after most of the material in the mixing tank 11 has been poured out, reducing the adhesion between the material and the inner wall of the mixing tank 11, improving the output effect of the material, and reducing the difficulty of cleaning the inner wall of the mixing tank 11 for subsequent maintenance personnel.
[0042] Reference Figures 3 to 4 The carding plate 24 has a first carding groove 241, and the ejector bar 25 has a second carding groove 251.
[0043] Users can adjust the angle between the locking plate 24 and the ejector bar 25 by adjusting the angle of their interlocking. When the ejector bar 25 is inclined, as the transmission plate 21 rotates around the mixing tank 11, it can squeeze the material adhering to the inner wall of the mixing tank 11 downward, thereby improving the squeezing effect between materials and improving the mixing effect of materials.
[0044] Reference Figures 2 to 3 A scraper 242 is fixedly connected to the lower end of the positioning plate 24, and the scraper 242 is in close contact with the wall of the mixing tank 11.
[0045] With the cooperation of the scraper 242, the material adhering to the bottom wall of the mixing tank 11 is turned up by the scraper 242, which improves the mixing effect of the material. At the same time, after the discharge plate 16 is opened, the material can be discharged from the discharge plate 16 by the extrusion of the scraper 242.
[0046] Reference Figures 2 to 3 A transmission gear 31 is fixedly connected to the upper end of the transmission column 22, and a transmission gear ring 32 is fixedly connected to the lower side of the cover 12. The transmission gear 31 meshes with the transmission gear ring 32.
[0047] Through the meshing relationship between the transmission gear 31 and the transmission gear ring 32, the transmission plate 21 rotates with the stirring column 14. At this time, the transmission plate 21 and the cover 12 rotate relative to each other, so that the transmission column 22 can stir the material close to the inner wall of the mixing tank 11 during the rotation of the transmission plate 21, thereby improving the stirring effect of the material and enabling the material to be stirred more quickly and thoroughly after being put into the mixing tank 11, thus improving the stirring efficiency.
[0048] Reference Figures 2 to 3 A sealing plate 33 is fixedly connected to the lower side of the cover 12;
[0049] By setting the sealing plate 33, the mud and sand are blocked during the concrete mixing process, preventing the concrete materials from interfering with the transmission gear 31 and transmission gear ring 32, ensuring the working environment of the transmission gear 31 and transmission gear ring 32, and enabling them to work stably.
[0050] Reference Figures 2 to 3 Several stirring hammers 151 are fixedly connected to the stirring blade 15;
[0051] By adding a mixing hammer 151 to the mixing blade 15, the contact area between the mixing blade 15 and the concrete material is increased when the mixing blade 15 rotates with the mixing column 14, thereby improving the mixing effect and increasing the mixing efficiency.
