Description

Technical Field

[0001] The utility model relates to the field of double-shaft mixers, and more specifically, to a clay brick mixer. Background Art

[0002] The main component of clay bricks is clay. Before production, the clay must be poured into a mixer and stirred with water to make it have good viscosity, and then pressed into a brick mold to form a brick body structure.

[0003] In the existing twin-shaft mixers for clay mixing, the mixing shafts are usually directly connected to the inner walls of the mixing box on both sides through bearings. Although sealing rings are provided at the connection between the mixing shaft and the mixing box wall inside the mixing box, the sealing rings will inevitably wear out over time, and muddy water mixed with sand will inevitably enter the gaps inside the bearings, increasing the probability of bearing wear and damage, and improving the maintenance rate. At the same time, it also increases the difficulty of maintenance and the cost of bearing replacement. Therefore, we propose a clay brick mixer to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a clay brick mixer, which does not use bearings to connect the two ends of the stirring shaft to the wall of the mixing box, but instead extends the two ends of the stirring shaft and connects them to the shaft seat and the output shaft of the reduction box respectively, and then directly welds a mud guard on the stirring shaft at the connection between the stirring shaft and the through hole, and finally seals the redundant gap with a sealing ring, so that the connection between the stirring shaft and the through hole can complete normal rotation, and can also prevent the mixing box from leaking material along the through hole. When the sealing ring is worn and damaged for a long time, there is no need to worry about the leaked muddy water mixed with sand damaging the bearing. The structural form of the upper and lower rings of the sealing ring is also convenient for disassembly and replacement, which improves the convenience of replacement while reducing the maintenance cost.

[0006] 2. Technical solution

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the specification of the present invention; obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without making creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 4 A clay brick mixer comprises a mixing box 1, a bracket 2 is fixedly welded at the bottom of the mixing box 1, two groups of through holes 101 are opened inside the mixing box 1, a stirring shaft 3 is arranged between the two corresponding through holes 101 in the horizontal direction, a reduction box 4, a coupling protection box 5 and a mounting seat 6 are fixedly installed on the top of one end of the bracket 2 in sequence, and a driving motor 7 is fixedly installed on one side of the mounting seat 6, a lifting frame 201 is fixedly welded on the top of the other end of the bracket 2, and two shaft seats 8 are fixedly installed on the lifting frame 201;

[0026] Mud guards 301 are fixedly welded on the two stirring shafts 3 located inside the through hole 101, and a redundant gap is formed between the outer edge of the mud guard 301 and the inner wall of the through hole 101, and a sealing ring 9 is arranged inside the redundant gap. The sealing ring 9 includes an upper ring 901 and a lower ring 902 with the same structure, and the upper ring 901 includes an installation ring segment 9011 and a filling ring segment 9012. The installation ring segment 9011 is fixedly installed on the mixing box 1 by screws, and the filling ring segment 9012 is filled inside the redundant gap.

[0027] The working principle of this kind of clay brick mixer is:

[0028] First, add a proper amount of dry clay into the mixing box 1, and then add a proper amount of water into the mixing box 1. At this time, the drive motor 7 can be started. The drive motor 7 transmits the driving force to the inside of the coupling protection box 5 through the drive shaft, and transmits the driving force to the input shaft of the reduction box 4 through the connection of the second coupling. Then, after the gear group is decelerated inside the reduction box 4, the two output shafts transmit the driving force to the two stirring shafts 3, driving the two stirring shafts 3 to rotate and stir. After stirring for a certain period of time, the drive motor 7 can be stopped, and the stirred clay can be discharged through the discharge opening;

[0029] When the sealing ring 9 is worn out and leaks occur over time, it is only necessary to remove the upper ring 901 and the lower ring 902 of the sealing ring 9 separately, and then install the new sealing ring 9 back to its original position. During installation, the filling ring segment 9012 is inserted into the redundant gap, and the installation ring segment 9011 is installed with screws. It is simple to replace.

[0030] Embodiment 2:

[0031] In view of the above embodiment 1, for further description, refer to Figure 1 The two output shafts on one side of the reduction box 4 are connected to one end of the corresponding two stirring shafts 3 through coupling 1, and the other ends of the two stirring shafts 3 are rotatably connected to the corresponding shaft seats 8. The driving shaft on one side of the driving motor 7 passes through the other side of the mounting seat 6 and extends to the inside of the coupling protection box 5. The input shaft on the other side of the reduction box 4 extends to the inside of the coupling protection box 5. The input shaft on the other side of the reduction box 4 is connected to the driving shaft on one side of the driving motor 7 through coupling 2. A discharge opening is provided on one side of the bottom of the mixing box 1, and a sealing plate is fixedly installed at the bottom of the discharge opening by bolts. Spiral stirring blades 302 are fixedly welded on the outer walls of the two stirring shafts 3, and a number of stirring piles 303 are also fixedly welded on the outer walls of the two stirring shafts 3 at equal distances.

[0032] By means of the spiral stirring blades 302 and stirring piles 303 fixedly welded on the outer wall of the stirring shaft 3, the contact area with the clay can be increased and the stirring effect can be improved. The mudguard 301 has the effect of preventing the clay from leaking out, and a redundant gap is formed between the outer edge of the mudguard 301 and the inner wall of the through hole 101, which facilitates the outer edge of the mudguard 301 to rotate inside the through hole 101 and prevents rotation jamming due to assembly accuracy. The sealing ring 9 includes an upper ring 901 and a lower ring 902 with the same structure, which can realize the split disassembly and assembly of the sealing ring 9 and improve the convenience of replacement.

[0033] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
