Technical Field

[0001] The utility model relates to the technical field of concrete mixing devices, in particular to a mixing device for high-flow-resistance concrete. Background Art

[0002] High flow-resistant concrete usually refers to high impact and abrasion-resistant concrete, which is specially designed to resist the scouring and abrasion of high-speed water flow, water flow carrying mud, sand or ice, and the mixing device is a device for stirring and mixing its raw materials.

[0003] The existing Chinese patent publication number is CN218365659U, which is a high-efficiency planetary concrete mixer. It can be seen from the contents recorded in its specification that when the device is in use, the material is mainly discharged through the discharge port. Since the inner bottom of the device is a flat structure, a relatively large amount of residue will appear at the bottom when discharging the material, requiring additional manual cleaning by the staff, thereby increasing the staff's workload in the later stage.

[0004] Therefore, it is necessary to provide a new high flow-resistant concrete mixing device to solve the above technical problems. Utility Model Content

A scraper is fixedly mounted on the top of the scraper, and the outer wall of the scraper abuts against and is slidably connected to the inner wall of the mixing drum.

[0008] A fixedly connected conical platform is installed on the inner bottom of the mixing cylinder. The center height of the conical platform is greater than the edge height, and the outer wall of the conical platform abuts against and is slidably connected to the bottom of the scraper.

[0009] Preferably, a feed trough is provided on one side of the interior of the conical table close to the edge, an installation groove is provided at the bottom of the mixing barrel opposite to the feed trough, the top of the installation groove is connected to the bottom of the feed trough, and a sealing component for sealing the feed trough is mounted inside the installation groove.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] See also Figures 1 to 6 The embodiment of the present invention provides a mixing device for high-flow-resistant concrete, which includes: a mixing drum 1.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 6 The top of the mixing drum 1 is provided with a top cover 2, and a mixing assembly 3 for mixing concrete is arranged between the top cover 2 and the mixing drum 1; the mixing assembly 3 includes a mixing rod 31, which is rotatably mounted inside the mixing drum 1, and a fixedly connected mixing blade 311 and a scraper 33 are mounted on the outer wall of the mixing rod 31, and a fixedly connected scraper bar 331 is mounted on the top of the scraper 33, and the outer wall of the scraper bar 331 is abutted against and slidably connected to the inner wall of the mixing drum 1; a fixedly connected conical platform 11 is mounted on the inner bottom of the mixing drum 1, the center height of the conical platform 11 is greater than the edge height, and the outer wall of the conical platform 11 is abutted against and slidably connected to the bottom of the scraper 33.

[0028] It should be noted that: through the setting of the conical platform 11, since the edge height of the conical platform 11 is lower than its center height, when unloading, the scraper 33 rotates and scrapes the gathered concrete to gather toward the edge of the mixing drum 1, so that the gathered concrete can be discharged downward from the unloading trough 12 more smoothly, and when unloading, the rotating scraper 33 and scraping bar 331 can scrape the inner bottom and inner side wall of the mixing drum 1, so that the unloading of concrete can be smoother, reducing the residual concrete on the mixing drum 1 and reducing the manual workload of the staff, thereby improving the user experience of the device.

[0029] In the embodiments of the present invention, please refer to Figures 1 to 6 A feeding trough 12 is provided on one side of the conical platform 11 near the edge, and a mounting groove 13 is provided at the bottom of the mixing drum 1 opposite to the feeding trough 12. The top of the mounting groove 13 is connected to the bottom of the feeding trough 12, and a sealing component 4 is mounted inside the mounting groove 13 to seal the feeding trough 12. The sealing component 4 includes a sealing piece 41, which is inserted into the feeding trough 12, and the side wall of the sealing piece 41 is abutted against and slidably connected to the inner wall of the mounting groove 13. The top of the sealing piece 41 is a sloped structure, and the sloped structure of the sealing piece 41 is adapted to the sloped structure of the top of the conical platform 11. The sealing component 4 also includes a support plate 43, which is fixedly mounted on the inner top of the mounting groove 13, and a fixedly connected cylinder 42 is mounted on the outer wall of the support plate 43, and the end of the cylinder 42 away from the support plate 43 is fixedly connected to the side wall of the sealing piece 41.

[0030] It should be noted that: by installing a conical platform 11 at the inner bottom of the mixing barrel 1 and opening a feed trough 12 inside it, the top of the feed trough 12 can be formed into an inclined structure, and then after the sealing piece 41 is inserted laterally into the feed trough 12, the feed trough 12 can be completely blocked so that the top of the conical platform 11 can still be in a flat surface structure, thereby reducing the phenomenon of raw materials getting stuck in the feed trough 12 during the mixing process, thereby improving the mixing comprehensiveness of the device.

[0031] In the embodiments of the present invention, please refer to Figures 1 to 6 An upper hopper 21 connected to the interior of the mixing barrel 1 is fixedly installed inside the top cover 2, a mixing motor 22 is fixedly installed on the top of the top cover 2, and the output end of the mixing motor 22 extends into the top cover 2 and is fixedly connected to the top end of the mixing rod 31.

[0032] It should be noted that: by installing the mixing motor 22, when in use, the working mixing motor 22 can drive the mixing rod 31 in the mixing assembly 3, so that the mixing assembly 3 can smoothly perform the rotation and mixing operation.

[0033] In the embodiments of the present invention, please refer to Figures 1 to 6 A fixed linkage frame 32 is mounted on the outer wall of the mixing rod 31, and a plurality of rotatably connected and annularly distributed linkage paddles 321 are inserted into the linkage frame 32.

[0034] It should be noted that: by setting up the linkage frame 32, during the rotation of the mixing rod 31, the linkage frame 32 can be driven to rotate synchronously. At this time, the linkage frame 32 can drive the linkage paddle 321 to rotate with the mixing rod 31 as the center point. At this time, the linkage paddle 321 is offset against the raw material, and its force can drive the linkage paddle 321 to rotate, thereby achieving auxiliary stirring and mixing of the raw materials, thereby improving the mixing effect of the device.

[0035] The working principle of the mixing device for high flow resistance concrete provided by the utility model is as follows:

[0036] When using the device, raw materials can be added to the interior of the mixing drum 1 through the upper hopper 21. After the raw materials are added, the mixing motor 22 can be controlled to drive the mixing rod 31 to rotate. The rotating mixing rod 31 can drive the mixing blades 311 on the outer wall to rotate, thereby achieving stirring and mixing of the raw materials.

[0037] During this process, the rotating mixing rod 31 can also drive the linkage paddle 321 to rotate through the linkage frame 32. At this time, the linkage paddle 321 can rotate by the force when it contacts the raw material, thereby achieving secondary mixing of the raw material. The combined mixing of the linkage paddle 321 and the mixing blade 311 can further improve the mixing effect of the device.

[0038] During this process, since the top of the blocking piece 41 and the surface of the conical platform 11 can form an integrated structure, the phenomenon of raw materials remaining in the discharge chute 12 during the mixing process can be reduced, thereby improving the overall stirring and mixing effect of the device;

[0039] After the mixing of the concrete is completed, the cylinder 42 can be controlled to retract, and the retracted cylinder 42 will drive the sealing piece 41 to slide inside the installation groove 13 until it is moved out from the bottom of the discharge chute 12, thereby releasing the blockage of the discharge chute 12, so that the mixed concrete can be discharged smoothly through the discharge chute 12. During this process, the rotating mixing rod 31 can drive the scraper 33 and the scraping strip 331 to scrape the inner bottom and inner side wall of the mixing drum 1, so that the concrete discharge can be cleaner, thereby reducing the workload of manual cleaning by the staff, and thus improving the user experience of the device.

[0040] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0041] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
