At the same time, ultra-high performance concrete has excellent wear resistance and explosion resistance.

[0015] It also includes multiple torsion shafts, and corresponding through holes are opened on the power input disk and the power output disk.

[0022] Compared with the prior art, the present invention has the following beneficial effects: The horizontal shaft mixer for ultra-high performance concrete materials is provided with a buffer seal assembly. When the vibration motor applies vibration force to the mixing shaft, the vibration force will be transmitted to the connecting shaft first. When the connecting shaft vibrates, since one of the bearings is not directly connected to the concrete mixing barrel, the vibration force of the connecting shaft will not be transmitted to the concrete mixing barrel through the bearing. The vibration of the connecting shaft will be transmitted to the spiral spring sheet, and the deformation sleeve will vibrate at this time. Therefore, the bearing between the connecting shaft and the concrete mixing barrel is not easy to be damaged, and there will be no leakage problem. In addition, the high-performance concrete will not contaminate the bearing. In addition, the vibration of the mixing shaft and the spiral blade during mixing makes the material mixing state more intense, and the fine powder mass is opened more quickly and thoroughly.

Since the mixing time of the main mixing motor is reduced overall, the mixing efficiency is improved and the purpose of energy saving and consumption reduction is achieved.

[0023] The horizontal shaft mixer for ultra-high performance concrete materials is provided with a buffer power component, so that the rotational force of the rotating motor does not directly act on the connecting shaft and the stirring shaft, but first drives the power input disk and then transmits it to the power output disk. A thick spring is provided to reduce axial vibration, and a damping rod is provided to reduce vibration in other directions. When power is transmitted, the torsion shaft can connect the power input disk and the power output disk, but cannot transmit vibration. Therefore, when the stirring shaft is mixing high-performance concrete, its rotational force can be transmitted freely, but the vibration force cannot be transmitted to the rotating motor, thereby avoiding damage to the rotating motor and achieving the effect of extending the service life of the rotating motor.

[0024] The horizontal-shaft mixer for ultra-high performance concrete materials is provided with two horizontal-shaft mixing assemblies. Under the action of the rotation of the two cross-mixing assemblies, the materials are not only quickly pushed from both sides to the middle, but the cross-spiral blades also cause the materials to shear each other, so that the materials form a large-scale three-dimensional reciprocating motion in the mixing drum, which can achieve the effect of energy-saving processing.

[0033] The support frame 1 is made of welded metal beams and can be fixed on the ground according to actual conditions to stably support the concrete mixing barrel 2. The rotating motor 6 and the vibration motor 7 are both commonly used components in the field of ultra-high concrete mixing in the prior art. The vibration motor 7 in this embodiment is in the form of shaft vibration, and different power specifications can be selected according to the actual production volume. The concrete mixing barrel 2 is a common shape of a twin-shaft mixer in the prior art.

[0034] The spiral spring sheet 502 is made of alloy, and the whole is formed by winding thin sheets in the shape of a mosquito coil. A circular ring is provided on the inner ring, which can be fixed to the outer ring of the bearing. The external connecting sleeve 503 is fixed to the spiral spring sheet 502 by spot welding. The spiral spring sheet 502 can support the entire cross-stirring assembly 3 when the specifications are selected, has a certain strength, and can buffer vibrations that are sufficient to damage the bearing. In the scheme, the shaft seal 504 is a circular structure, which can connect the bearing and the deformation sleeve 505, and prevent concrete from entering between the connecting shaft 501 and the bearing.

[0035] The connecting sleeve 503 is made of a variable material, preferably synthetic rubber, and needs to be kept away from temperature as much as possible. After the concrete is mixed, it needs to be rinsed in time to prevent the concrete from corroding the connecting sleeve 503.

[0036] The buffer power assembly 4 includes a power input disc 401, a power output disc 402, a power input shaft 403, a damping rod 404 and a spring assembly 405. One end of the power input shaft 403 is fixedly connected to the main shaft of the rotating motor 6, and the other end is fixedly connected to the power input disc 401. The power input shaft 403 is rotatably supported by the concrete mixing barrel 2. The power output disc 402 is located on the side of the power input disc 401 away from the rotating motor 6.

The spring assembly 405 is provided with a plurality of equidistantly distributed spring assemblies, and both ends of the spring assembly 405 are respectively connected to the power input disk 401 and the power output disk 402; It also includes multiple torsion shafts 407. Corresponding through holes 408 are opened on the power input disk 401 and the power output disk 402. The two ends of the torsion shaft 407 pass through the two through holes 408 and are movably connected thereto. The outer ends of the torsion shaft 407 are located on both sides of the through holes 408 and are fixedly installed with limit rings 409 to prevent the torsion shaft 407 from escaping from the through holes 408.

[0037] A T-type coupling is installed at the connection between the power input shaft 403 and the power input disk 401, and a similar coupling is also used to connect the connecting shaft 501 and the power output disk 402. The damping rod 404 is a hydraulic damping rod with a vibration buffering effect, and the torsion shaft 407 is a hollow metal rod that has been reinforced. The diameter of the perforation 408 is larger than the torsion shaft 407. The torsion shaft 407 may not contact the inner wall of the perforation 408 in daily life, and the limit ring 409 can prevent the torsion shaft 407 from moving relative to the power input disk 401 or the power output disk 402. When torsion occurs between the power input disk 401 and the power output disk 402, the torsion shaft 407 can intervene to transmit power.

[0038] The spring assemblies 405 are arranged parallel to each other. The spring assemblies 405 include a high-strength rod 4051 and a thick spring 4052. Two high-strength rods 4051 are provided and are coaxially arranged. The thick spring 4052 is located between the two high-strength rods 4051. Both ends of the thick spring 4052 are respectively fixed to the ends of the two high-strength rods 4051 that are close to each other, and the ends of the two high-strength rods 4051 that are far away from each other are respectively fixed to the power output disk 402 and the side of the power output disk 402 that is close to each other.

[0039] The elastic coefficient of the thick spring 4052 needs to meet the support requirements, and the thick spring 4052 is in a tensile state when not subjected to force, and can produce both tensile deformation and compressive deformation after being subjected to force.

[0040] The diameter of the power input disk 401 is larger than that of the power output disk 402, and the two are coaxially arranged. The ends of the multiple damping rods 404 close to the power output disk 402 are gathered together, and the ends close to the power input disk 401 are dispersed. The power input disk 401 and the power output disk 402 are fixed with an inclined shaft 410 on one side close to the universal joint 406. The inclined shafts 410 of the two correspond to each other, and the other end of the inclined shaft 410 is fixed to the universal joint 406. The multiple damping rods 404 form a conical structure. The torsion shaft 407 and the damping rod 404 have the same angle, and a plurality of torsion shafts 407 form a conical structure. The damping rod 404 and the torsion shaft 407 are distributed around the central axis of the power input disc 401 and the power output disc 402, and the two are cross-arranged.

[0041] The cross stirring assembly 3 includes a stirring shaft 301 and a spiral blade 302 . The spiral blade 302 surrounds the stirring shaft 301 and is fixed to the stirring shaft 301 . Both ends of the stirring shaft 301 are fixedly connected to two connecting shafts 501 .

[0042] The spiral blades 302 of the two cross stirring assemblies 3 are staggered, which increases the contact area between the blades and the material compared with a single-blade mixer. During stirring, the material is not only quickly pushed from both sides to the middle, but the cross spiral blades 302 also cause the material to shear each other, so that the material forms a large-scale three-dimensional reciprocating motion in the mixing drum.

[0043] Two V-shaped frames 8 are fixedly installed outside the concrete mixing barrel 2 , the power input shaft 403 penetrates the V-shaped frames 8 and is rotatably connected thereto, and the rotary motor 6 is fixedly connected to the V-shaped frames 8 .

[0044] A bearing is installed at the center of the V-frame 8 for supporting the power input shaft 403 .

[0045] The deformation sleeve 505 is a trumpet-shaped structure, with a large diameter end connected to the connecting sleeve 503 and a small diameter end connected to the shaft seal 504 .

[0046] Concrete inlet and outlet ports 9 are installed at the top and bottom of the concrete mixing barrel 2.

[0047] A concrete inlet and outlet 9 is provided for adding and discharging concrete.

[0048] like Fig.10 As shown, as another embodiment of the present application, if an integral vibration type vibration motor 7 is used, the vibration motor 7 is connected to the stirring shaft 301 in the form of a shaft direct connection, which requires a shock absorbing device to be used to connect the vibration motor 7 and the concrete mixing barrel 2. Preferably, a spring is installed at the connection to reduce the vibration force of the vibration motor 7 on the concrete mixing barrel 2 and extend the service life of the equipment. Since the two embodiments both adopt the form of direct connection of the vibration shaft, the mixing time of the main mixer is reduced overall, so that the mixing efficiency is improved and the purpose of energy saving and consumption reduction is achieved.

[0049] When in use, when the rotary motor 6 rotates, the power input disc 401 is first driven to rotate through the power input shaft 403. When the power input disc 401 and the power output disc 402 are twisted, the torsion shaft 407 starts to connect the two to achieve power transmission, thereby the stirring shaft 301 starts to rotate. When the stirring shaft 301 rotates, it can stir the ultra-high performance concrete through the spiral blades 302. When the rotational force is transmitted, the vibration motor 7 starts to work. When the vibration motor 7 is working, the vibration force will be first transmitted to the connecting shaft 501. When the connecting shaft 501 vibrates, since one of the bearings is not directly connected to the concrete mixing barrel 2, the connecting shaft 50 1 will not be transmitted to the concrete mixing barrel 2 through the bearing, the vibration of the connecting shaft 501 will be transmitted to the spiral spring sheet 502, and the deformable sleeve 505 will vibrate at this time, so the bearing between the connecting shaft 501 and the concrete mixing barrel 2 is not easily damaged, and the connecting shaft 501 at the other end of the stirring shaft 301 is the same, so the stirring shaft 301 can vibrate freely inside the concrete mixing barrel 2 and is not affected by the outer shell of the concrete mixing barrel 2, so the rotation connection between the two will not be damaged, which can not only vibrate and stir the concrete, but also avoid leakage, bearing failure and other problems. When the stirring is completed, the deformable sleeve 505 needs to be cleaned immediately to avoid the concrete from corroding the deformable sleeve 505.

[0050] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0051] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
