Description

Technical Field

[0001] The utility model belongs to the technical field of mixing devices, and particularly relates to a mixing device for mortar production. Background Art

[0002] Dry-mixed mortar generally refers to a granular or powdery material obtained by physically mixing aggregates, inorganic binders, additives, etc. that have been dried and screened at a certain ratio, and is transported to the construction site in bags or bulk form. After adding water and mixing, it can be directly used, which greatly facilitates the use of mortar production during construction at the construction site.

[0003] However, at present, the mortar mixing devices on the market lack a screening structure for raw materials. It is easy for some large lumps to enter the mixing barrel in the raw materials. If not cleaned out in time, it is likely to cause uneven mixing of the mortar, resulting in a decline in the quality of the mortar. It will also cause damage to the inside of the mixing barrel due to the overly large dry mortar. At the same time, the overall structure of the existing mixing device is too large. When it is necessary to move its position, it is necessary to disassemble it or use other transportation equipment for auxiliary handling, which is very time-consuming and laborious, and the movement is not convenient enough.

[0027] Bottom plate 1, with support feet 11 fixedly installed at the four corners of the bottom of the bottom plate 1. A mixing barrel 12 is fixedly installed at the top of the bottom plate 1. A feeding cylinder 13 is fixedly installed on one side of the top of the bottom plate 1 close to the mixing barrel 12 through a bracket. A pipeline is provided for communication between the feeding cylinder 13 and the mixing barrel 12.

[0028] Screening assembly 2, the screening assembly 2 is arranged inside the feeding cylinder 13. The screening assembly 2 includes a sieve plate 21 movably installed inside the feeding cylinder 13. A rotating shaft 25 is movably installed on one side of the sieve plate 21. A number of cams 26 are fixedly installed on the outer side of the rotating shaft 25.

[0029] Moving assembly 3, the moving assembly 3 is arranged on both sides of the bottom plate 1. The moving assembly 3 includes adjusting frames 31 symmetrically installed on both sides of the bottom plate 1. Two threaded blocks 33 are movably installed inside the adjusting frames 31. A moving plate 35 is movably installed on one side of the adjusting frame 31. Two universal wheels 36 are movably installed on one side of the moving plate 35. A push rod 37 is hinged between the two threaded blocks 33 and the moving plate 35.

[0030] Specifically, a sieve plate 21 is movably installed inside the feeding cylinder 13. The sieve plate 21 is in sliding fit with the inner wall of the feeding cylinder 13. Two support plates 22 are fixedly installed inside the feeding cylinder 13. The two support plates 22 are arranged below the sieve plate 21. The two support plates 22 are symmetrically arranged on both sides of the sieve plate 21. Limit rods 23 are fixedly installed at the tops of the two support plates 22. The limit rods 23 penetrate to the top of the sieve plate 21. A return spring 24 is connected between each of the two support plates 22 and the sieve plate 21. The return spring 24 is arranged outside the limit rod 23. A rotating shaft 25 is movably installed inside the feeding cylinder 13. The rotating shaft 25 is arranged below the sieve plate 21. A number of cams 26 are fixedly installed on the outer side of the rotating shaft 25. A servo motor 27 is installed on the outer side of the feeding cylinder 13 close to the rotating shaft 25 through a fixed seat.

[0031] As can be seen from the above, by arranging the sieve plate 21 inside the feeding cylinder 13, the raw materials are screened. Only the sieved raw materials can enter the mixing barrel 12, while some large lumps will be screened out and will not enter the mixing barrel 12, avoiding problems such as damage inside the mixing barrel 12 caused by over-large mortar dry materials.

[0032] During specific use, pour the mortar raw materials into the feeding cylinder 13, and then start the servo motor 27 to drive the rotating shaft 25 to rotate. During the rotation of the rotating shaft 25, the sieve plate 21 will be repeatedly pushed upward by the cams 26, and under the action of the return spring 24, the sieve plate 21 will complete the reset, thus realizing the up-and-down jitter screening of the sieve plate 21 and having a higher screening efficiency.

[0033] Embodiment 2:

[0034] Please refer toFigure 1 and Figure 5 As shown in Figure 5 and , adjusting frames 31 are symmetrically installed on both sides of the bottom plate 1.

Push rods 37 are hinged between the two threaded blocks 33 and the moving plate 35.

[0036] As can be seen from the above, by arranging the movable moving plate 35 on both sides of the bottom plate 1 and arranging the universal wheels 36 on one side of the moving plate 35, the moving function of the device is realized. When the device is working normally, the feet 11 contact the ground to stably support the weight of the device. When the device needs to be moved, the moving plate 35 can be moved downward, and the universal wheels 36 contact the ground and lift the bottom plate 1 by a certain distance, so that the device can be pushed to move, making it easier to handle during transportation.

[0037] During specific use, first start the second motor 34. The second motor 34 drives the threaded rod 32 to rotate. Then the two threaded blocks 33 approach each other and push the moving plate 35 downward through the push rod 37 until the universal wheels 36 lift the device.
