Description

Technical Field

[0001] The invention belongs to the technical field of concrete production, and in particular relates to a vibrating mixer for producing lightweight concrete. Background Art

[0002] In the concrete production process, mixing (or stirring) refers to the process of mixing cement, aggregate (sand, gravel), water and possible admixtures (such as water reducers, retarders, etc.) in a specific proportion and uniformly mixing them through mechanical stirring.

[0003] In the mixing production process, when the aggregates (sand, gravel) are transported to the hopper, they often enter the hopper by falling from a high altitude. Since the aggregates (sand, gravel) themselves have a certain weight, they will have a certain impact force when falling. Under the action of these impact forces, the connection points of the hopper will often produce mechanical fatigue, and the aggregates (sand, gravel) will also rebound when impacting in the hopper, causing the aggregates (sand, gravel) to gather at a certain point, which is not conducive to the homogenization of the cement slurry.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0029] like Figures 1 to 6 As shown, the present invention proposes a vibrating mixer for lightweight concrete production, comprising a hopper 16, a connecting frame 18, a lifting base 25, a lower spring 22 and an upper spring 28. An even number of lifting bases 25 are provided at the lower portion of the hopper 16. Each set of lifting bases 25 is provided with a set of upper springs 28 and lower springs 22 at the upper and lower parts respectively. Each set of lifting bases 25 cooperates with the lower springs 22 and upper springs 28 to feedback the vibration transmitted by the hopper 16. Multiple sets of lifting bases 25 are evenly distributed on both sides of the hopper 16. A set of connecting frames 18 is provided at the rear of the lifting bases 25 on both sides. The connecting frames 18 are used to provide rotation support points for the lifting base 25 , and a set of bases 19 are respectively provided on the upper and lower parts of each set of the connecting frames 18 .

[0030] In this embodiment, first, the hopper 16 is the main container for holding concrete raw materials and performing vibration mixing, and the lifting bases 25 are arranged in even groups and symmetrically distributed on both sides of the hopper. Their main function is to receive and transmit vibration energy, and the connecting frame 18 at the rear of the lifting base 25 can provide a rotation support point for the lifting base 25 and coordinate the vibration direction.

[0031] First, after the concrete raw materials enter the hopper 16, the concrete raw materials will inevitably impact the hopper 16 under the influence of gravity during the falling process. Under the influence of this impact force, the hopper 16 will vibrate. Secondly, due to the operation of other vibration-generating parts, the hopper 16 will inevitably continue to vibrate.

[0032] The supporting bases 25 located on both sides of the hopper 16 can transmit the vibration generated by the hopper to other parts to prevent the hopper 16 from mechanical fatigue during the continuous vibration process. In addition, the even-arrayed supporting bases 25 cooperate with the three-dimensional vibration mode to achieve rapid homogenization of concrete aggregate and cement paste, which improves the mixing efficiency compared with the traditional vibration mode.

[0033] Furthermore, it also includes a lower bracket 1, an upper frame 2, a moving wheel 3, a transverse frame 4 and a suspension bracket 5; Among them, the lower bracket 1 includes four groups of column feet, and a group of upper frames 2 are fixedly connected to the upper part of the lower bracket 1. The lower part of the four groups of column feet in the lower bracket 1 is respectively provided with a group of moving wheels 3, and the middle part of the upper frame 2 is provided with a group of transverse frames 4. The front part of the upper frame 2 is provided with two groups of suspension brackets 5, and the two groups of suspension brackets 5 are respectively located directly above the two groups of connecting frames 18.

[0034] Furthermore, it also includes four sets of external hanging frames 6, lower hanging plates 7, elastic dampers 8, hooks 9 and feeding channels 10; Among them, the two rear groups of external hanging frames 6 are symmetrically distributed directly below the transverse frame 4, and a group of lower hanging plates 7 are fixedly connected to the bottom of each group of external hanging frames 6. A group of elastic dampers 8 are provided at the bottom of each group of lower hanging plates 7, and a group of hooks 9 are fixed to the inside of each group of elastic dampers 8.

[0035] Furthermore, it also includes a storage area 11 and a flash 12; Among them, four groups of burrs 12 are provided on the outside of the feed channel 10, two groups of burrs 12 are located at the rear of the feed channel 10, and two groups of burrs 12 are located at the front of the feed channel 10. Each group of burrs 12 is connected to the outside of a group of hooks 9, and a group of storage areas 11 is provided in the middle of the feed channel 10.

[0036] Furthermore, it also includes a support base 13, an eccentric motor 14 and an insertion port 15; Among them, the support base 13 is arranged at the bottom of the feed channel 10, the eccentric motor 14 is located at the tail of the support base 13, the hopper 16 is arranged at the front of the suspension bracket 5, and the hopper 16 is fixedly connected to multiple groups of lifting bases 25. An insertion port 15 is opened in the middle of the hopper 16, and the front of the feed channel 10 is located inside the insertion port 15.

[0037] Furthermore, a stripper plate 17 is also included.

[0038] The discharge plate 17 is movably connected to the bottom of the hopper 16 , and the two sets of connecting frames 18 are fixed to the front of the lower bracket 1 . The upper and lower parts of the two sets of connecting frames 18 are each provided with a base 19 .

[0039] In this embodiment, first, the lower bracket 1 includes four groups of column feet to form a stable foundation, and because its bottom is equipped with moving wheels 3, the equipment can be switched between mobile and fixed modes. The upper frame 2 is welded to the top of the lower bracket 1 to form the main load-bearing platform of the equipment, and a suspension bracket 5 is provided at the front, and a transverse frame 4 is integrated in the middle to enhance torsional rigidity.

[0040] The suspension bracket 5 can be made of two sets of high-strength steel brackets located directly above the connecting frame 18, and the dynamic decoupling of the vibration mechanism and the main frame is achieved through a pin connection.

[0041] The external hanging frame 6 consists of two groups and is symmetrically distributed below the transverse frame 4. It serves as the top load-bearing structure of the suspension system and is cast with high-strength alloy steel. The lower hanging plate 7 is rigidly connected to the external hanging frame 6 to form a first-level buffer interface for vibration energy transmission, and a group of elastic dampers 8 are provided at the bottom of each group of lower hanging plates 7, so that the elastic dampers 8 form a secondary buffer interface.

[0042] Subsequently, since four groups of burrs 12 are provided on the outside of the feed channel 10, a group of hooks 9 are connected to the outside of each group of burrs 12, and a group of hooks 9 are fixed to the inside of each group of elastic dampers 8, the feed channel 10 is actually suspended at the lower part of the upper frame 2.

[0043] In addition, the support base 13 is arranged directly below the feed channel 10, and the eccentric motor 14 is located at the tail of the support base 13, so that when the eccentric motor 14 located at the tail of the support base 13 starts working, the eccentric motor 14 will drive the support base 13 to vibrate, and the support base 13 will drive the feed channel 10 to vibrate.

[0044] At this time, the vibration of the conveying channel 10 will be offset by the elastic damper 8 connected to it to prevent the conveying channel 10 from generating mechanical fatigue, and a group of storage areas 11 are provided in the middle of the conveying channel 10. At this time, the concrete raw materials can be placed in the storage areas 11. As the conveying channel 10 starts to vibrate under the action of the outside world, the raw materials in the storage areas 11 will be continuously transported forward due to the vibration.

[0045] Furthermore, it also includes a lower rotating base 20, a lower connecting column 21, a lower circular base 23 and a lower connecting base 24; Among them, the upper parts of the two groups of the bases 19 located below are movably connected to a group of lower rotating bases 20, and the front part of each group of lower rotating bases 20 is provided with a group of lower connecting columns 21. The outside of each group of the lower connecting columns 21 is fixed with a group of lower springs 22, and the front part of each group of the lower springs 22 is provided with a group of lower circular bases 23. The lower connecting columns 21 can move inside the lower circular base 23, and the front part of each group of the lower circular bases 23 is provided with a group of lower connecting bases 24. The lifting base 25 is rotatably connected to the lower connecting base 24.

[0046] Furthermore, it also includes an upper rotating base 26, an upper connecting column 27, an upper circular base 29 and an upper connecting base 30; Among them, the front part of the two groups of the bases 19 located above is provided with a group of upper rotating bases 26, the front part of each group of the upper rotating bases 26 is provided with a group of upper connecting columns 27, the outside of each group of the upper connecting columns 27 is fixed with a group of upper springs 28, the front part of each group of the upper springs 28 is provided with a group of upper circular bases 29, the upper connecting columns 27 can move inside the upper circular bases 29, and the front part of each group of the upper circular bases 29 is provided with a group of upper connecting bases 30.

[0047] Furthermore, the upper connecting base 30 is rotatably connected to the lower connecting base 24 .

[0048] In this embodiment, first, an insertion port 15 is opened in the middle of the hopper 16, and the front part of the feed channel 10 is located inside the insertion port 15, so that the vibration of the feed channel 10 will inevitably be transmitted to the hopper 16, and the lifting base 25 is evenly distributed on both sides of the hopper 16. At this time, the vibration of the hopper 16 will inevitably be transmitted to the lifting base 25.

[0049] The lifting base 25 is rotatably connected to the lower connecting base 24. At this time, the vibration is gradually transmitted from the lifting base 25 to the lower connecting base 24. A group of lower connecting bases 24 is provided at the front of each group of lower circular bases 23. At this time, the vibration is transmitted to the lower circular base 23 through the lower connecting base 24.

[0050] A group of lower circular bases 23 are provided at the front of each group of lower springs 22. At this time, the vibration is transmitted through the lower circular bases 23 and finally sent to the lower springs 22, and is offset by the elastic damping of the lower springs 22. A group of lower springs 22 are fixed to the outside of each group of lower connecting columns 21. The lower connecting columns 21 can move inside the lower circular bases 23. When the elastic damping of the lower springs 22 offsets the vibration of the hopper 16, the lower springs 22 will inevitably drive the lower connecting columns 21 to move.

[0051] The movement of the lower connecting column 21 will further offset the vibration of the hopper 16, and the guide sleeve of the lower circular base 23 will constrain the lateral deviation of the lower connecting column 21, ensuring that the lower spring 22 only bears axial load.

[0052] The upper connecting base 30 is rotatably connected to the lower connecting base 24, and the lifting base 25 is rotatably connected to the lower connecting base 24. At this time, the vibration transmitted by the lifting base 25 will inevitably be transmitted to the upper connecting base 30, and each group of upper circular bases 29 is provided with a group of upper connecting bases 30 in front. At this time, the vibration is gradually transmitted, and the vibration is transmitted to the upper circular base 29 through the upper connecting base 30.

[0053] Because each set of upper springs 28 is provided with a set of upper circular bases 29 in front, the vibration transmitted to the upper circular bases 29 will be offset by the elastic damping of the upper springs 28, and each set of upper connecting columns 27 is fixed with a set of upper springs 28 on the outside, and the upper connecting columns 27 can move inside the upper circular bases 29.

[0054] When the elastic damping of the upper spring 28 offsets the vibration of the hopper 16, the upper spring 28 will inevitably drive the upper connecting column 27 to move, and the movement of the upper connecting column 27 will further offset the vibration of the hopper 16, and the guide sleeve of the upper circular base 29 will constrain the lateral deviation of the upper connecting column 27, ensuring that the upper spring 28 only bears axial load.

[0055] In summary, a multi-stage shock absorption design is formed by utilizing the elastic damping of the upper spring 28 and the lower spring 22. Moreover, the system ensures the conveying efficiency while also ensuring the conveying segregation rate of commercial concrete through the multi-stage shock absorption design of rigid-flexible coupling, making this embodiment suitable for scenarios with strict requirements on concrete homogeneity, such as high-rise pumping and prefabricated component production.
