Description

Technical Field

[0001] This invention relates to the technical field of concrete preparation, and in particular to a rapid concrete preparation machine for use in subsidence mining areas. Background Technology

[0002] A concrete preparation machine is a device used to prepare concrete. Its main function is to thoroughly mix a certain proportion of gravel, sand, cement powder, and water. It has wide applications in building construction and bridge construction. Especially in some subsidence mining areas, it is necessary to quickly prepare concrete to pour into the collapsed areas to prevent further subsidence.

[0003] In the prior art, patent application number 202220465111.X discloses a high-performance concrete preparation device, patent application number 202222107833.0 discloses a concrete preparation equipment, and patent application number 202210490669.8 discloses a high-efficiency concrete preparation system. The main structure of the above-mentioned concrete preparation devices consists of a box, a filtration mechanism, and a mixing and discharging mechanism. The filtration mechanism and the mixing and discharging mechanism are both installed in the box. In use, the stones are first put into the filtration mechanism to filter out the large stones, so that the stones of appropriate particle size and cement powder and other raw materials enter the mixing and discharging mechanism to be mixed with water. After the various raw materials are fully mixed into concrete in the filtration mechanism, the concrete is discharged and used. During its use, it was found that when preparing concrete, the stones need to be filtered before they can be mixed with other raw materials. The stones cannot be mixed with other concrete raw materials while being filtered, resulting in low preparation efficiency and the inability to quickly prepare large quantities of concrete. This can easily affect the construction progress when pouring concrete into collapsed mining areas. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a rapid concrete preparation machine for subsidence mining areas, which has high concrete preparation efficiency and can ensure the demand for rapid concrete pouring in subsidence mining areas.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows.

[0006] A rapid concrete preparation machine for subsidence mining areas includes a base plate and a housing. The housing is fixedly installed on the upper part of the base plate. The housing has a chamber inside, with an opening at the top. It also includes a filtering and initial mixing mechanism, a conveying mechanism, and a mixing and discharging mechanism. The filtering and initial mixing mechanism is installed in the upper part of the housing chamber and has both mixing and filtering functions. The conveying mechanism is installed in the middle of the housing chamber and has a conveying function. The mixing and discharging mechanism is installed in the lower part of the housing chamber and has both mixing and discharging functions. A transparent observation window is provided on the housing. When preparing concrete in subsided mining areas, the solid materials required for concrete preparation, such as gravel, cement powder, sand, and additives, are first added to a filtering and initial mixing mechanism. This mechanism filters the gravel and simultaneously pre-mixes it with other materials. Gravel of appropriate particle size and other raw materials are then discharged through the filtering and initial mixing mechanism into a conveying mechanism. The conveying mechanism then transports these pre-mixed materials to a mixing and discharging mechanism. A certain amount of water is then added to the mixing and discharging mechanism to fully mix the solid materials and water into concrete. The prepared concrete is then discharged through the mixing and discharging mechanism, collected, and transported to the subsided mining area for pouring. This method, by filtering and screening the gravel while pre-mixing the solid materials, and then further mixing them in the mixing and discharging mechanism, achieves high mixing efficiency and high concrete preparation efficiency, ensuring the need for rapid concrete pouring in subsided mining areas and demonstrating high practicality.

[0007] Preferably, the primary mixing filter includes a crushing mechanism, a support plate, a motor A, a rotating shaft, a filter cylinder, two sets of spiral blades, and a cover plate. Motor A is fixedly installed on the left end of the housing via the support plate. The rotating shaft is tilted and rotatably installed on the housing, with its left end connected to the output end of motor A. The filter cylinder is fixedly installed on the right end of the rotating shaft, coaxial with it, and installed at an angle. The filter cylinder has an internal cavity. A crushing mechanism with a crushing function is located on the right side of the filter cylinder. Two sets of equidistant spiral blades are arranged on the inner wall of the filter cylinder. Multiple sets of filter holes communicating with the cavity are located between the two sets of spiral blades. An inlet communicating with the cavity is located at the top of the filter cylinder, and the cover plate is installed outside the inlet. When preparing concrete, the cover plate is first opened, and then stones and other solid raw materials for concrete preparation are added into the cavity of the filter cylinder. Then, motor A is turned on, driving the rotating shaft to rotate, which in turn drives the filter cylinder to rotate. The filter cartridge rotates, driving two sets of spiral blades to rotate. During this rotation, the spiral blades transport the stones and other materials inside the filter cartridge cavity from right to left. Because the filter cartridge is installed at an angle, the stones and materials, after being transported to the left end of the filter cartridge, will fall back to the right end due to gravity, and then continue to be transported in a cyclical manner. During this cyclical transport, the stones and other solid materials undergo initial mixing, and the stones collide and compress with each other, crushing large particles. At the same time, stones of appropriate particle size and other solid materials are gradually discharged through multiple filter holes on the filter cartridge onto the conveying mechanism. Afterward, the stones and other solid materials are transported by the conveying mechanism to the mixing and discharge mechanism to be mixed with water to form concrete for use. This method not only filters stones but also allows them to be compressed against each other, crushing large particles, and also allows for initial mixing of solid materials, improving mixing efficiency and making it convenient to use.

[0008] Preferably, the crushing mechanism includes a motor B, a rotating shaft, a disc, a bearing, and a connecting block. Motor B is fixedly mounted on the right end of the housing. The rotating shaft is rotatably mounted on the housing, with its right end connected to the output end of motor B. The disc is fixedly mounted on the left end of the rotating shaft and rotatably mounted on the bearing, which is fixedly mounted on the inner wall of the right side of the filter cartridge. The connecting block is fixedly mounted on the left end of the disc, and multiple sets of crushing blades are arranged on the outer wall of the connecting block. The rotating shaft, disc, and filter cartridge are coaxial. When it is necessary to crush large particles of stone remaining in the filter cartridge cavity, the mechanism is opened... Motor A drives the filter cylinder to rotate via a shaft, causing the spiral blades to convey the stones from left to right until they reach the vicinity of the crushing blades. Then, motor B is activated, causing a disc to rotate via a shaft. The connecting block, in turn, rotates the crushing blades, which break up large stones during rotation. The shaft is then reversed, allowing the crushed stones to be conveyed through the filter cylinder to the left side. Stones of appropriate particle size are then discharged through multiple filter holes for continued use. This method facilitates the crushing of large stones and improves convenience.

[0009] Preferably, the mixing and discharging mechanism includes a mixing cylinder, a conveying cylinder, a sealing door, a bushing, a connecting frame, a water conveying mechanism, a driving mechanism, and a reinforcing plate. The mixing cylinder is tilted and rotatably installed on the lower part of the support plate, with its left end located on the left side of the support plate. A mixing chamber is provided inside the mixing cylinder, with both ends of the mixing chamber being open. The conveying cylinder is rotatably connected to the right side of the mixing cylinder, and a conveying chamber is provided inside the conveying cylinder, communicating with the mixing chamber of the mixing cylinder. The sealing door is installed on the left side of the mixing cylinder and has a handle. The output end of the conveying mechanism communicates with the conveying chamber of the conveying cylinder, which is located on the right side of the mixing cylinder and is coaxial with it. Spiral conveying blades are provided on the inner wall of the mixing cylinder. The mixing cylinder is rotatably installed on the bushing, which is fixedly installed on the inner wall of the housing via the connecting frame. A reinforcing plate is provided on the connecting frame. The conveying cylinder is coaxial with the mixing cylinder, and the output end of the water conveying mechanism communicates with the conveying chamber of the conveying cylinder. The mechanism is installed on the mixing drum and the housing. The drive mechanism drives the mixing drum to rotate. When stones and other solid materials of appropriate particle size are conveyed into the conveying chamber of the conveying drum by the conveying mechanism, the stones and other materials will slide into the mixing chamber of the mixing drum due to gravity. Then, a certain amount of water is conveyed into the conveying chamber of the conveying drum by the water conveying mechanism. Then, the water, stones and other solid materials are mixed in the mixing chamber of the mixing drum. At the same time, the drive mechanism is turned on to make the mixing drum rotate. The mixing drum drives the spiral conveying blades to rotate. The spiral conveying blades convey the various materials in the mixing chamber of the mixing drum to the right. Then, due to gravity, they slide to the left side of the mixing chamber of the mixing drum, so that the various materials and water are fully mixed into concrete in the mixing chamber of the mixing drum. Then, the sealing door is opened to allow the mixed concrete in the mixing chamber of the mixing drum to be discharged through the left end of the mixing drum for collection. This facilitates the mixing of various materials and improves convenience.

[0010] Preferably, the water conveying mechanism includes a water pump, a water delivery pipe, and a water inlet pipe. The water pump is fixedly installed on the housing, and the output end of the water pump is connected to the conveying chamber of the conveying cylinder through the water delivery pipe. The input end of the water pump is provided with a water inlet pipe. When conveying water into the conveying chamber of the conveying cylinder, the input end of the water inlet pipe is connected to an external water source, and then the water pump is turned on, so that the water is conveyed into the conveying chamber of the conveying cylinder in sequence through the water inlet pipe, the water pump, and the water delivery pipe. This facilitates the conveying of water into the conveying cylinder and improves convenience.

[0011] Preferably, the driving mechanism includes a gear ring, a gear, a drive shaft, and a drive motor. The gear ring is fixedly installed on the outer wall of the mixing cylinder and meshes with the gear. The gear is fixedly installed on the drive shaft, which is rotatably installed on a support plate. The input end of the drive shaft is connected to the drive motor, which is fixedly installed on the housing. When the mixing cylinder is rotated, the drive motor is turned on, and the drive motor rotates the gear through the drive shaft. The gear rotates the mixing cylinder through the gear ring, promoting the mixing of materials and water in the mixing chamber of the mixing cylinder and improving the efficiency of concrete preparation.

[0012] Preferably, the conveying mechanism includes a connecting plate, a conveying plate, a conveying pipe, a power motor, a rotating shaft, spiral blades, and a support frame. The conveying plate is obliquely fixedly installed on the inner wall of the housing via the connecting plate. The conveying plate is located between the filter cylinder and the mixing cylinder. A discharge hole is provided on the right side of the conveying plate, which communicates with the upper part of the conveying pipe. A support plate communicating with the conveying cavity is provided on the conveying cylinder. The lower part of the conveying pipe communicates with the conveying cavity of the conveying cylinder via the support plate. The power motor is fixedly installed on the housing via the support frame. The rotating shaft is rotatably installed on the housing. The spiral blades are fixedly installed on the rotating shaft, with the lower end of the spiral blades close to the upper end of the conveying plate. The left end of the rotating shaft is connected to the output end of the power motor. When the stones and solid materials in the filter cylinder cavity fall onto the conveying plate through multiple sets of filter holes, the power motor is turned on. The power motor drives the rotating shaft to rotate, and the rotating shaft drives the spiral blades to rotate. The rotating spiral blades push the solid materials and stones on the upper part of the conveying plate to the discharge hole on the right side of the conveying plate. Then, the solid materials fall into the conveying cavity of the conveying cylinder via the conveying pipe, which facilitates the conveying of materials.

[0013] Preferably, it also includes a sealing plate and bolts. The lower part of the box body is provided with a cleaning port communicating with the chamber. The sealing plate is installed on the outside of the cleaning port by bolts. With the above configuration, when it is necessary to clean some solid impurities that have fallen into the chamber of the box body, the sealing plate can be opened to clean the solid impurities inside the chamber of the box body, which improves convenience.

[0014] Preferably, the connecting block is cone-shaped, with multiple sets of crushing blades evenly distributed on the outer side wall of the connecting block; with the above arrangement, large stones are initially crushed by the crushing blades on the left side of the connecting block before entering the right side of the connecting block for further crushing, which facilitates the crushing of stones.

[0015] Due to the adoption of the above technical solutions, the technical progress achieved by this invention is as follows.

[0016] This invention has high efficiency in preparing concrete, which can meet the demand for rapid concrete pouring in collapsed mining areas, and is highly practical. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figures 1 to 10 A rapid concrete preparation machine for subsidence mining areas includes a base plate 1, a box body 2, a filtering and initial mixing mechanism, a conveying mechanism, and a mixing and discharging mechanism. The box body 2 is equipped with a transparent observation window and is fixedly installed on the upper part of the base plate 1. The box body 2 has an internal chamber with an opening at the top. The filtering and initial mixing mechanism is installed in the upper part of the chamber and has both mixing and filtering functions. The conveying mechanism is installed in the middle of the chamber and has a conveying function. The mixing and discharging mechanism is installed in the lower part of the chamber and has both mixing and discharging functions. When preparing concrete in subsidence mining areas, the machine first adds the solid materials required for concrete preparation, such as gravel, cement powder, sand, and additives, to the filtering and initial mixing mechanism. The system filters gravel and simultaneously mixes it with other materials. Gravel of appropriate particle size and other raw materials are discharged through the initial mixing mechanism into a conveying mechanism. The conveying mechanism then transports this initially mixed material to a mixing and discharging mechanism. A certain amount of water is added to the mixing and discharging mechanism to fully mix the solid materials and water into concrete. The prepared concrete is then discharged through the mixing and discharging mechanism, collected, and transported to the subsidence mining area for pouring. This system, by filtering and screening gravel while initially mixing solid materials, and then further mixing them in the mixing and discharging mechanism, achieves high mixing efficiency and high concrete preparation efficiency, ensuring the need for rapid concrete pouring in subsidence mining areas and demonstrating high practicality.

[0031] like Figure 3 and Figure 2The primary mixing filtration mechanism includes a crushing mechanism, a support plate 3, a motor A4, a rotating shaft 5, a filter cartridge 6, two sets of spiral blades 7, and a cover plate 9. The motor A4 is fixedly mounted on the left end of the housing 2 via the support plate 3. The rotating shaft 5 is tilted and rotatably mounted on the housing 2, with its left end connected to the output end of the motor A4. The filter cartridge 6 is fixedly mounted on the right end of the rotating shaft 5, coaxial with it, and installed at an angle. The filter cartridge 6 has an internal cavity, and a crushing mechanism is located on the right side of the filter cartridge 6. The crushing mechanism has… The filter cylinder 6 has a crushing function. Two sets of equidistant spiral blades 7 are arranged on the inner wall of the filter cylinder 6. Multiple sets of filter holes 8 communicating with the cavity are provided on the filter cylinder 6, and all sets of filter holes 8 are located between the two sets of spiral blades 7. A feed inlet communicating with the cavity is provided at the top of the filter cylinder 6, and a cover plate 9 is installed outside the feed inlet. When preparing concrete, first open the cover plate 9, then add the aggregate and other solid raw materials for concrete preparation into the cavity of the filter cylinder 6. Then, turn on the motor A4, which drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the filter cylinder 6 to rotate, which in turn drives two sets of spiral blades 7 to rotate. During the rotation, the two sets of spiral blades 7 transport the stones and other raw materials in the cavity of the filter cylinder 6 from right to left. Since the filter cylinder 6 is installed at an angle, the stones and raw materials will fall back to the right end of the filter cylinder 6 due to gravity after being transported to the left end. This process is repeated. During the repeated transport of the stones and other solid raw materials in the cavity of the filter cylinder 6, the stones are initially mixed. The stones collide and squeeze with each other, crushing large stones. At the same time, stones of appropriate particle size and other solid raw materials are gradually discharged to the conveying mechanism through multiple sets of filter holes 8 on the filter cylinder 6. After that, the stones and other solid raw materials are transported to the mixing and discharge mechanism to be mixed with water to form concrete for use. This method can filter stones while squeezing them together, crushing large stones, and initially mixing solid materials, improving mixing efficiency and making it convenient to use.

[0032] like Figure 3 and Figure 4The crushing mechanism includes a motor B10, a rotating shaft 11, a disc 12, a bearing 13, and a connecting block 14. The motor B10 is fixedly mounted on the right end of the housing 2. The rotating shaft 11 is rotatably mounted on the housing 2, and its right end is connected to the output end of the motor B10. The disc 12 is fixedly mounted on the left end of the rotating shaft 11 and rotatably mounted on the bearing 13, which is fixedly mounted on the inner wall of the right side of the filter cartridge 6. The connecting block 14 is fixedly mounted on the left end of the disc 12, and multiple sets of crushing blades are arranged on the outer wall of the connecting block 14. The rotating shaft 11, the disc 12, and the filter cartridge 6 are coaxial. When it is necessary to crush large stones remaining in the cavity of the filter cartridge 6... During crushing, motor A4 is turned on. Motor A4 drives the filter cylinder 6 to rotate via rotating shaft 5, causing the spiral blades 7 to rotate. The spiral blades 7 convey the stones from left to right until the stones are near the crushing blades. Then, motor B10 is turned on. Motor B10 drives the disc 12 to rotate via rotating shaft 11, causing the connecting block 14 to rotate. The connecting block 14 drives the crushing blades to rotate. During the rotation, the crushing blades crush large stones. Then, rotating shaft 5 is reversed, so that the crushed stones are conveyed through the filter cylinder 6 to the left side of the filter cylinder 6. Stones of appropriate particle size are discharged through multiple sets of filter holes 8 and can be used again. This facilitates the crushing of large stones and improves convenience.

[0033] like Figure 1 and Figure 6The mixing and discharging mechanism includes a mixing cylinder 15, a conveying cylinder 16, a sealing door 17, a bushing 18, a connecting frame 19, a water conveying mechanism, a drive mechanism, and a reinforcing plate 36.

A handle 39 is provided on the sealing door 17. The output end of the conveying mechanism communicates with the conveying chamber of the conveying drum 16. The conveying drum 16 is located on the right side of the mixing drum 15 and is coaxial with the mixing drum 15. Spiral conveying blades are provided on the inner wall of the mixing drum 15. The mixing drum 15 is rotatably mounted on the bushing 18. The bushing 18 is fixedly mounted on the inner wall of the housing 2 via a connecting frame 19. A reinforcing plate 36 is provided on the connecting frame 19. The conveying drum 16 is coaxial with the mixing drum 15. The water conveying mechanism... The output end is connected to the conveying chamber of the conveying cylinder 16. The drive mechanism is installed on the mixing cylinder 15 and the housing 2. The drive mechanism is used to drive the mixing cylinder 15 to rotate. When stones and other solid materials of a reasonable particle size are conveyed into the conveying chamber of the conveying cylinder 16 through the conveying mechanism, the stones and other materials will slide into the mixing chamber of the mixing cylinder 15 due to gravity. Then, a certain amount of water is conveyed into the conveying chamber of the conveying cylinder 16 through the water conveying mechanism. Then, the water, stones and other solid materials are mixed in the mixing chamber of the mixing cylinder 15. At the same time, the drive mechanism is turned on to make the mixing cylinder 15 rotate. The mixing cylinder 15 drives the spiral conveying blades to rotate. The spiral conveying blades convey the various materials in the mixing chamber of the mixing cylinder 15 to the right. Then, due to gravity, they slide into the left side of the mixing chamber of the mixing cylinder 15, so that the various materials and water are fully mixed into concrete in the mixing chamber of the mixing cylinder 15. Then, the sealing door 17 is opened to allow the mixed concrete in the mixing chamber of the mixing cylinder 15 to be discharged and collected through the left end of the mixing cylinder 15. This facilitates the mixing of various materials and improves convenience.

[0034] like Figure 6 The water conveying mechanism includes a water pump 21, a water conveying pipe 22, and a water inlet pipe 35. The water pump 21 is fixedly installed on the housing 2. The output end of the water pump 21 is connected to the conveying chamber of the conveying cylinder 16 through the water conveying pipe 22. The input end of the water pump 21 is provided with a water inlet pipe 35. When conveying water into the conveying chamber of the conveying cylinder 16, the input end of the water inlet pipe 35 is connected to an external water source. Then, the water pump 21 is turned on, so that the water is conveyed into the conveying chamber of the conveying cylinder 16 in sequence through the water inlet pipe 35, the water pump 21, and the water conveying pipe 22. This facilitates the conveying of water into the conveying cylinder 16 and improves convenience.

[0035] like Figure 5 and Figure 6The drive mechanism includes a gear ring 23, a gear 24, a drive shaft 25, and a drive motor 26. The gear ring 23 is fixedly installed on the outer wall of the mixing cylinder 15 and meshes with the gear 24. The gear 24 is fixedly installed on the drive shaft 25, which is rotatably installed on the support plate 3. The input end of the drive shaft 25 is connected to the drive motor 26, which is fixedly installed on the housing 2. When the mixing cylinder 15 is rotated, the drive motor 26 is turned on. The drive motor 26 rotates the gear 24 through the drive shaft 25, and the gear 24 rotates the mixing cylinder 15 through the gear ring 23, promoting the mixing of materials and water in the mixing chamber of the mixing cylinder 15 and improving the concrete preparation efficiency.

[0036] like Figure 7 The conveying mechanism includes a connecting plate 27, a conveying plate 28, a conveying pipe 29, a power motor 31, a rotating shaft 32, a spiral blade 33, and a support frame 34. The conveying plate 28 is obliquely fixedly installed on the inner wall of the housing 2 via the connecting plate 27. The conveying plate 28 is located between the filter cylinder 6 and the mixing cylinder 15. A discharge hole is provided on the right side of the conveying plate 28, which communicates with the upper part of the conveying pipe 29. A support plate 30 communicating with the conveying cavity is provided on the conveying cylinder 16. The lower part of the conveying pipe 29 communicates with the conveying cavity of the conveying cylinder 16 via the support plate 30. The power motor 31 is fixedly installed on the housing 2 via the support frame 34, and the rotating shaft 32 is rotatably installed on the housing. 2. The spiral blade 33 is fixedly installed on the rotating shaft 32. The lower end of the spiral blade 33 is close to the upper end of the conveying plate 28. The left end of the rotating shaft 32 is connected to the output end of the power motor 31. When the stones and solid materials in the cavity of the filter cylinder 6 fall onto the conveying plate 28 through multiple sets of filter holes 8, the power motor 31 is turned on. The power motor 31 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the spiral blade 33 to rotate. The rotating spiral blade 33 pushes the solid materials and stones on the upper end of the conveying plate 28 to the discharge hole on the right side of the conveying plate 28.

[0039] Example 2

[0040] Based on Example 1, the toothed ring 23 and gear 24 can be replaced with two sets of sprockets, which are then installed on the mixing cylinder 15 and the drive shaft 25 respectively. The two sets of sprockets are connected by a chain, which can also drive the mixing cylinder 15 to rotate. At the same time, the spiral conveying blades inside the mixing cylinder 15 can be replaced with stirring blades, which can also achieve the effect of stirring and mixing.

[0041] In summary, the main beneficial effects of this invention are as follows:
