Description

Technical Field

[0001] The invention relates to a concrete mixer, in particular to an anti-blocking material concrete mixer for concrete production. Background Art

[0002] In the concrete production process, it is necessary to place a variety of materials for concrete production in a mixer for mixing, so that the materials are fully mixed and finally discharged; however, there are many disadvantages in the concrete mixing and unloading process. For example, when the concrete mixer is mixing the materials, the materials will accumulate on the outer periphery of the inner wall of the mixer due to the centrifugal effect of mixing, and some materials are also prone to accumulation and wall hanging on the outer periphery due to their high viscosity, which makes it difficult for these materials to participate in the mixing operation. It takes a long time to fully mix the concrete materials, resulting in a long operating time of the mixer and excessive energy consumption. In the unloading process, the materials will also accumulate in the mixer due to the repose angle due to the conical discharge port, making it difficult to unload and causing blockage. The current solution to the blockage and material accumulation during mixing is very simple, which is to hammer the mixer tank vigorously to destroy the stability of the materials in the mixer to cause collapse for unloading and help full mixing. However, the current hammering method easily destroys the tank structure and causes damage to the mixer.

[0035] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position. Example 1

[0036] like Figure 1-Figure 3 As shown, a concrete mixer for preventing blocking of concrete production includes a mounting frame 1, a vertical frame 2, an annular frame 3, a pillar 4, a mixing tank 5, a guiding device 6, a blocking device 7, a displacement device 8 and an air supply device 9. The mounting frame 1 is an annular structure frame with a central opening. The vertical frames 2 are fixedly connected to the left and right sides of the mounting frame 1. The annular frame 3 is fixedly connected between the upper sides of the vertical frames 2. The pillar 4 is fixedly connected to the annular structure in the middle of the mounting frame 1. The mixing tank 5 is fixedly installed on the upper side of the pillar 4. The mixing tank 5 is an existing vertical mixing station. The mixing tank 5 is used for mixing concrete materials. Four sets of guiding devices are arranged on the outside of the mixing tank 5. Device 6, the guiding devices 6 are interconnected with the space in the stirring tank 5, the guiding devices 6 are used to guide the airflow in the stirring tank 5, and the guiding devices 6 are provided with blocking devices 7, the blocking devices 7 are used to control the interconnection between the guiding devices 6 and the outside, so that the stirring tank 5 can keep the guiding devices 6 closed when no airflow is needed, the upper side of the annular frame 3 is provided with a displacement device 8, the displacement device 8 is used to perform a surrounding motion, and an air supply device 9 is provided at the displacement device 8, the air supply device 9 is driven by the displacement device 8 to perform a surrounding motion, and the air supply device 9 is used for the guiding device 6 to perform air supply work.

[0037] When producing concrete for mixing operations, in order to avoid the pile-up of concrete materials when releasing materials after mixing, the material repose angle maintains the stability of the material accumulation and is difficult to collapse and unload, etc., which causes the material to be blocked due to other reasons, or when the concrete materials are mixed in the mixing tank 5, due to the viscosity and other characteristics of the materials, the material fluidity is poor, so that part of the materials are in the inner and outer layers of the mixing tank 5 during the mixing process, which is difficult to be fully mixed, resulting in a long mixing time, and then the mixer operation time is long and there is a waste of energy. The anti-blocking concrete mixer for concrete production can be used; the anti-blocking concrete mixer for concrete production can be installed above the collection bin rack of the concrete mixing station through the mounting frame 1; when mixing the concrete materials in the mixing tank 5, the operator can control the air supply device 9 to perform a circumferential operation by controlling the displacement device 8, so that the air supply device 9 runs to one of the guide devices 6, and then controls the air supply device 9 to dock with the guide device 6. At this time, the operator The blocking device 7 connected to the guide device 6 can be operated so that the blocking device 7 no longer blocks the communication between the guide device 6 and the mixing tank 5, and then the air supply device 9 is controlled to carry out a single high-pressure airflow into the guide device 6, so that the high-pressure airflow enters the mixing tank 5 in the form of an air cannon, so that the high-pressure airflow destroys the accumulation of materials with poor fluidity in the mixing tank 5, increases the fluidity of the materials in the mixing tank 5, and then improves the degree of sufficient mixing of concrete, so that concrete production is accelerated, the operating time of the mixer is reduced, and the waste of energy is reduced, which achieves the purpose of energy saving and environmental protection, and at the same time, the accumulation of materials can be avoided during the unloading process of the mixing tank 5; after the high-pressure airflow is sent into the guide device 6, the blocking device 7 at this position can be operated to block it, and then the air supply device 9 can be operated to disengage from the guide device 6; and the displacement device 8 can be controlled again to drive the air supply device 9 to operate in a circular manner to supply air to other guide devices 6. Example 2

[0038] like Figure 8 , Fig.10 and Fig.11 As shown, the guiding device 6 includes a first mounting plate 61 and a Y-shaped joint 62. The number of the first mounting plates 61 is four. The first mounting plates 61 are evenly mounted on the outer periphery of the stirring tank 5. The first mounting plates 61 are fixedly connected with Y-shaped joints 62. The Y-shaped joints 62 all have an upwardly inclined pipe structure and a straight pipe structure. The straight pipe structure of the Y-shaped joint 62 extends into the stirring tank 5. The Y-shaped joint 62 is interconnected with the stirring tank 5. The side of the straight pipe structure of the Y-shaped joint 62 that is not interconnected with the stirring tank 5 is connected to the blocking device 7.

[0039] When it is necessary to bombard the accumulated materials in the mixing tank 5 with an air cannon, the air supply device 9 can be controlled to dock with the oblique upward tube structure of one of the Y-shaped joints 62, and the blocking device 7 at this position can be operated so that the blocking device 7 no longer blocks the communication between the oblique upward tube structure of the Y-shaped joint 62 and the straight tube structure to the mixing tank 5, and the straight tube structure of the Y-shaped joint 62 is kept blocked from the outside world. At this time, the air supply device 9 is controlled to deliver high-pressure airflow, so that the airflow is delivered into the mixing tank 5 through the oblique upward tube structure and the straight tube structure of the Y-shaped joint 62, so that the high-pressure airflow bombards the accumulated concrete materials in the form of an air cannon, causing the materials to collapse in the mixing tank 5, thereby improving the fluidity of the materials so that they can actively participate in the mixing.

[0040] like Figure 10-12 As shown, the blocking device 7 includes a fixed seat 71, a first movable pair 72 and a plug 73. The fixed seats 71 are respectively fixedly connected to the outer sides of the first mounting plate 61. The fixed seats 71 are all fixedly connected with the first movable pair 72. The first movable pair 72 is a horizontal guide rail and guide sleeve movable pair. The movable part of the first movable pair 72 is a guide sleeve structure. The movable part of the first movable pair 72 is all fixedly connected with a plug 73. The head of the plug 73 is a rubber ball head structure. The plug 73 is respectively sealed and nested in the side of the straight tube structure of the Y-shaped joint 62 that is not interconnected with the stirring tank 5 at the corresponding position. The head of the plug 73 is located at the center of the Y-shaped joint 62. When the rubber ball head structure of the plug 73 extends into the middle of the Y-shaped joint 62, i.e., the three-way junction, the three openings of the Y-shaped joint 62 are not interconnected, and the plug 73 maintains its position through the friction between its rubber head structure and the inner wall of the Y-shaped structure.

[0041] After the air supply device 9 is docked with one of the oblique upward tube structures of the Y-shaped joint 62, the operator can push the moving part of the first moving pair 72 at this position to move outward, so that the moving part of the first moving pair 72 drives the plug 73 to move outward, so that the plug 73 is separated from the central part of the Y-shaped joint 62 at this position, so that the oblique upward tube structure of the Y-shaped joint 62 and the straight tube structure are interconnected with the stirring tank 5, so that the high-pressure airflow can pass smoothly; after completing the high-pressure airflow delivery, the moving part of the first moving pair 72 can be pushed to move inward, so that the plug 73 is re-displaced to the middle position of the Y-shaped joint 62, so that the three openings of the Y-shaped joint 62 are not interconnected, thereby preventing the mixture of material and water in the stirring tank 5 from overflowing.

[0042] like Figure 3As shown, the displacement device 8 includes an electric circular track 81, a displacement frame 82 and a connecting frame 83. The electric circular track 81 is installed on the upper side of the circular frame 3. The electric circular track 81 is servo-controlled. The moving part of the electric circular track 81 is fixedly connected to the displacement frame 82. The lower side of the displacement frame 82 is fixedly connected to the connecting frame 83. The connecting frame 83 is used to install the air supply device 9.

[0043] The electric circular track 81 is started and controlled, and the electric circular track 81 can drive the displacement frame 82 and the connecting frame 83 to perform a circular operation, thereby driving the air supply device 9 to perform a circular operation.

[0044] like Figure 4-Figure 7 As shown, the air supply device 9 includes an electric slide rail 91, a second moving pair 92, a pneumatic gun head 93 and a sealing ring layer 94, the electric slide rail 91 is fixedly connected to the connecting frame 83, the electric slide rail 91 is servo-controlled, the electric slide rail 91 is vertically installed and displaced, the moving part of the electric slide rail 91 is a double-head structure, the moving part of the electric slide rail 91 is fixedly connected with the second moving pair 92 on the side facing the mixing tank 5, the second moving pair 92 is vertically installed, the second moving pair 92 is used for smooth guiding, the moving parts of the second moving pair 92 are fixedly connected with the pneumatic gun head 93, the pneumatic gun head 93 is vertically installed, and the output structure on the lower side of the pneumatic gun head 93 is fixedly connected with a sealing ring layer 94, and the sealing ring layer 94 is used to seal the oblique upward pipe structure of the Y-shaped joint 62.

[0045] When the air cannon head 93 moves to above one of the Y-shaped joints 62, the electric slide rail 91 can be controlled to operate, so that the electric slide rail 91 drives its moving part and the air cannon head 93 to move downward, so that the air cannon head 93 is sealed and docked with the oblique upward tube structure of the Y-shaped joint 62 at this position through the sealing ring layer 94, and then the air cannon head 93 is controlled to start and output high-pressure airflow into the Y-shaped joint 62, so as to bombard the accumulated materials in the mixing tank 5 in the form of an air cannon; after completing the above work, the electric slide rail 91 can be controlled to run upward for reset, so that the air cannon head 93 drives the sealing ring layer 94 to separate from the docking with the Y-shaped joint 62 at this position. Example 3

[0046] like Figure 6 , Fig.11 and Fig.12As shown, a linkage device 10 is also included, and the linkage device 10 includes a connecting seat 101, a guide rail 102 and a driving component 11. The linkage device 10 is respectively arranged at the moving parts of the first moving pair 72. The linkage device 10 is used to control the independent and automatic operation of the plug 73. The moving parts of the first moving pair 72 are fixedly connected with the connecting seat 101, and the connecting seat 101 is fixedly connected with the guide rail 102. The guide rail 102 is used for guiding work. A driving component 11 is provided at the moving part of the electric slide rail 91. The driving component 11 is connected to the guide rail 102 and enables the guide rail 102 to run automatically, thereby controlling the moving parts of the first moving pair 72 and the plug 73 to run automatically.

[0047] When the electric slide rail 91 drives its moving part and the blast head 93 to move up and down, the driving assembly 11 will also move up and down. When the blast head 93 moves downward to dock with one of the Y-shaped joints 62, the driving assembly 11 will also contact the guide rail 102 at that position and keep matching. As the blast head 93 moves downward, the driving assembly 11 will also drive the guide rail 102 at that position to move outward, so that the plug 73 at that position also moves outward, so that the plug 73 is separated from the center position of the Y-shaped joint 62. The Y-shaped joint 62 is placed so that the upward oblique tube structure and the straight tube structure of the Y-shaped joint 62 are interconnected with the stirring tank 5; when the high-pressure airflow is delivered, the air cannon head 93 is controlled to move upward, and the driving assembly 11 will also move upward, so that the driving assembly 11 drives the guide track 102 to move inward, thereby causing the plug 73 to move inward and re-enter the center position of the Y-shaped joint 62. In this way, the plug 73 can be automatically and independently operated without manual operation, thereby improving the degree of automation and the speed and efficiency of bombarding the accumulated materials.

[0048] like Figure 6 As shown, the driving assembly 11 includes an extension rod 111 and a guide wheel 112. The extension rod 111 is fixedly connected to the other side of the double-headed moving part structure of the electric slide rail 91. The lower side of the extension rod 111 is fixedly connected to the guide wheel 112, and the guide wheel 112 can cooperate with the guide rail 102 respectively.

[0049] When the electric slide rail 91 drives its moving parts to move up and down, the extension rod 111 and the guide wheel 112 will also move up and down. When the guide wheel 112 enters into one of the guide rails 102, the guide wheel 112 keeps running vertically downward and will drive the guide rail 102 to move outward, thereby causing the plug 73 to move outward; when the guide wheel 112 runs upward for reset, the guide wheel 112 will move vertically upward and drive the guide rail 102 to move inward, thereby causing the plug 73 to move inward.

[0050] like Figure 13-Figure 16 As shown, it also includes a vibration device 12, which includes a sealing frame 121, a pressure relief pipe 122, a connecting plate 123, a third moving pair 124, a vibration wall plate 125 and a drainage component 13. There are four groups of vibration devices 12, and the vibration devices 12 are evenly arranged on the inner wall of the mixing tank 5. The vibration device 12 is used to prevent the high-viscosity material in the mixing tank 5 from hanging on the wall due to the centrifugal effect of stirring. If the material hangs on the wall, it will be difficult for the hanging material to participate in the stirring, resulting in a longer stirring time before it can be stirred evenly. The vibration device 12 can shake off the material when it is piled up and hanging on the wall, so that the material actively participates in the stirring, further improves the stirring efficiency, reduces the operating time of the mixer, and further makes the mixer energy-saving. Four groups of sealing frames 121 are evenly installed on the inner wall of the mixing tank 5. The sealing frames 121 are staggered with the first mounting plate 61. The outer wall of the mixing tank 5 is evenly installed with a pressure relief pipe 122, and the installation position of the pressure relief pipe 122 is located between each of the sealing frames 121. The outer wall of the stirring tank 5 is evenly installed with four connecting plates 123, and the position of the connecting plates 123 corresponds to the sealing frame 121. The connecting plates 123 are fixedly connected with the third moving pair 124, and the third moving pair 124 is horizontally installed. The third moving pairs 124 are all guide rail and guide sleeve moving pairs. The moving parts of the third moving pair 124 are all guide rails. The guide rails of the third moving pair 124 extend into the stirring tank 5. The moving parts of the third moving pair 124 are located in the stirring tank 5. The positions of the moving parts are fixedly connected with vibration wall plates 125, and the vibration wall plates 125 are respectively sleeved in the sealing frame 121 corresponding to the position to keep the edge sealed. Four groups of drainage components 13 are evenly installed on the outer periphery of the stirring tank 5. The position of the drainage components 13 corresponds to the vibration wall plates 125. The drainage components 13 are used to guide the airflow into the space between the sealing frame 121 and the vibration wall plates 125. The drainage components 13 and the guiding device 6 are on the same horizontal plane.

[0051] The air cannon head 93 is docked with one of the drainage components 13, and the air cannon head 93 is controlled to output a high-frequency, slightly high-pressure airflow, so that the high-frequency, slightly high-pressure airflow enters the space between the sealing frame 121 and the vibrating wall plate 125, so that the high-frequency, slightly high-pressure airflow pushes the vibrating wall plate 125 to make a small movement in the sealing frame 121, and the pressure relief pipe 122 will also balance the air pressure in the space between the sealing frame 121 and the vibrating wall plate 125, thereby causing the vibrating wall plate 125 to vibrate, so that the materials piled on the surface of the vibrating wall plate 125 are vibrated and out of contact, thereby avoiding the phenomenon of concrete materials hanging on the wall and improving the degree of mixing participation of the materials.

[0052] like Figure 13-Figure 16 As shown, the drainage assembly 13 includes a second mounting plate 131 and a gas supply connector 132. The number of the second mounting plates 131 is four. The second mounting plates 131 are evenly mounted on the outer periphery of the mixing tank 5. The position of the second mounting plate 131 corresponds to the vibration wall plate 125. The second mounting plate 131 is fixedly connected with a gas supply connector 132. The gas supply connector 132 is a 90-degree elbow. The gas supply connector 132 is interconnected with the space between the sealing frame 121 and the vibration wall plate 125. The upper end surface of the gas supply connector 132 is in the same horizontal plane as the upper end surface of the Y-shaped connector 62.

[0053] The pneumatic cannon head 93 is controlled to dock with the gas supply connector 132 , and the pneumatic cannon head 93 is controlled to output a high-frequency and slightly high-pressure airflow into the gas supply connector 132 , thereby causing the vibration wall panel 125 to vibrate.

[0054] like Figure 1 As shown, a dust cover 14 is also included. The dust cover 14 is installed on the upper side of the mixing tank 5, and the dust cover 14 covers the lower side space of the mixing tank 5.
