Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering, and particularly relates to an assembly building block manufacturing device based on the recycling of construction waste. Background Art

[0002] With the continuous development of society, the construction industry has developed vigorously. Concrete is an essential material in house construction. For the conservation and recycling of resources, it is necessary to recycle waste concrete when houses are demolished and rebuilt, so as to facilitate subsequent processing.

[0003] Currently, the following problems still exist in the process of treating waste concrete by existing equipment. When waste concrete is crushed, ground, filtered, and screened, due to the high humidity of some waste concrete, the crushed and ground concrete often contains a large amount of water and fine particles, making the crushed and ground concrete material sticky and viscous. As a result, it is easy to cause blockage during the filtration and screening process, thereby reducing the screening efficiency. In severe cases, it may even lead to equipment failure, seriously affecting the resource utilization process of waste concrete. Therefore, there are deficiencies and it cannot meet the user's needs. Thus, it is necessary to further improve.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies to provide an assembly building block manufacturing device based on the recycling of construction waste, in order to achieve a more practical value purpose. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an assembly building block manufacturing device based on the recycling of construction waste, which is achieved by the following specific technical means:

[0006] An assembly building block manufacturing device based on the recycling of construction waste includes a fixed frame, and a movable frame movably arranged on the fixed frame. It also includes a mixing tank assembly arranged on the movable frame for mixing concrete materials, a crushing assembly arranged on the mixing tank assembly for crushing concrete waste, a screening assembly arranged in the crushing assembly for filtering and screening the materials after crushing the concrete waste, and a drying assembly for drying the materials containing moisture.

[0007] The screening assembly includes a screening component with an inner cavity opened inside. A number of sieve pipes are fixedly assembled in the screening component for filtering and screening the materials after crushing the concrete waste and arranged at equal intervals.

[0008] Inside the screening component, several striking components are arranged longitudinally and equidistantly, and the striking components are located between the screening pipes. On the inner wall of the screening component on the side facing the drying component, several uniform impellers are provided. The drying air flow produced by the operation of the drying component is conveyed into the inner cavity of the screening component, while drying the moisture-containing material in the flowing screening pipes. At the same time, the drying air flow blows the striking components to make the striking components generate vibration frequencies by themselves, and the striking components are used to knock on the screening pipes to make the screening pipes generate vibration effects.

[0009] As a further description of the above technical solution: Through the setting of the screening component and the drying component, the screening speed of the concrete material can be accelerated through the screening pipes, the screening efficiency of the concrete material can be improved, and at the same time, the drying treatment of the moisture-containing concrete material is realized. The uniform impellers drive the hot air flow to blow to each corner of the inner cavity of the screening component, effectively heating the screening pipes in all directions, without heating dead angles, avoiding the possibility that the material adheres to the inner wall of the screening pipes due to moisture and causing material blockage, and further improving the screening efficiency of the concrete material.

[0010] Further, the drying component includes a dryer fixedly assembled on the side of the crushing component. One side of the dryer close to the crushing component is fixedly connected to the transmission part through an air inlet pipe. An air vent groove for the circulation of the hot air flow is opened inside the transmission part. The side of the transmission part away from the air inlet pipe is fixedly connected to and communicated with the screening component.

[0011] As a further description of the above technical solution: The uniform impellers drive the hot air flow to blow to each corner of the inner cavity of the screening component, effectively heating the screening pipes in all directions, thereby drying the moisture-containing concrete material, without heating dead angles, and effectively strengthening the drying effect of the material.

[0012] Further, the screening pipe includes a drying section and an acceleration section, and the inner diameter of the drying section is larger than that of the acceleration section.

[0013] As a further description of the above technical solution: Since the inner diameter of the drying section is larger than that of the acceleration section, when the material passes through the smaller inner diameter in the middle of the acceleration section, the cross-sectional area of the acceleration section becomes smaller, and the flow rate of the material will increase, thereby improving the screening speed of the concrete material and effectively improving the screening efficiency of the concrete material.

[0014] Further, the striking component includes an elastic rope. The front and rear ends of the elastic rope are fixedly connected to the inner cavity wall of the screening component. A plurality of vibration plates and striking balls are arranged equidistantly on the elastic rope, and the vibration plates and the striking balls are arranged in sequence;

[0015] Among them, the striking balls are located between the screening pipes.

[0016] As a further description of the above technical solution: The hot air flow drives the striking assembly to generate a vibration frequency, and the elastic rope driven by the vibration drives the striking ball to strike the outer wall of the sieve pipe, so that the sieve pipe and even the screening component synchronously generate a vibration frequency, and the concrete material is separated from the sieve pipe by the acting force during vibration, further accelerating the screening effect of the concrete material flow.

[0017] Further, the mixing tank assembly includes an upper tank body and a lower tank body. The movable frame is rotatably connected to the bottom of the lower tank body through a movable shaft, and the movable frame is fixedly connected to the outer side wall of the upper tank body through a fixed shaft;

An inner ring sleeve is fixedly assembled on the inner wall of the lower tank body, and a slider corresponding to the chute is fixedly provided on the outer wall of the inner ring sleeve. The slider is located in the chute, and the upper tank body and the lower tank body are rotatably installed through the outer ring sleeve and the inner ring sleeve.

[0019] As a further description of the above technical solution: When the lower tank body rotates, it drives the inner ring sleeve to rotate synchronously, and drives the slider to slide synchronously in the chute of the outer ring sleeve, so that the lower tank body can rotate and stir, and the upper tank body remains stationary, further improving the applicability of the device.

[0020] Further, the crushing assembly includes a crushing seat fixedly assembled on the upper tank body. A crushing shell is fixedly assembled on the upper side of the crushing seat. A second feed hopper for feeding concrete waste is fixedly installed on the upper side of the crushing shell. A first driving mechanism is provided on the front side of the crushing seat. A gear set is provided on the front side of the crushing shell, and the gear set includes two meshing gears. Two crushing teeth are arranged inside the crushing shell. The output end of the first driving mechanism drives the two gears of the gear set to mesh and drive each other, and the two crushing teeth rotate relatively to crush the concrete waste;

[0021] A plurality of auxiliary plates are arranged at equal intervals on the inner wall of the crushing shell, and the auxiliary plates are installed in cooperation with the crushing teeth. A filter plate for filtering the material after crushing the concrete waste is arranged inside the crushing shell and directly below the crushing teeth.

[0022] As a further description of the above technical solution: The first driving mechanism is driven to drive the crushing teeth to crush the concrete waste. When the concrete material is not fully crushed, the rotating crushing teeth can be used to crush its particles again, so as to achieve repeated crushing of the inadequately crushed concrete waste, thereby ensuring the uniformity of the discharged concrete material, improving the crushing effect of the concrete waste, and facilitating the secondary utilization of the concrete waste.

[0023] Further, a stirring assembly for driving the lower tank body is provided on the outer side of the fixing frame. The stirring assembly includes a housing fixedly assembled on the fixing frame, and a second driving mechanism is fixedly arranged inside the housing. The output end of the second driving mechanism is fixedly connected with a driving gear;

[0024] The stirring assembly further includes a fixed gear ring fixedly assembled on the outer periphery of the lower tank body, and the driving gear is connected with the fixed gear ring through meshing.

[0025] As a further description of the above technical solution: The second driving mechanism drives the driving gear to rotate, and the meshing action between the driving gear and the fixed gear ring drives the lower tank body to rotate self - rotatably, and the rotation of the lower tank body stirs the raw materials.

[0026] Further, a regulating assembly for adjusting the steering of the stirring tank assembly and a limiting assembly for limiting the steering angle of the stirring tank assembly are provided on one side of the fixing frame away from the stirring assembly;

[0027] The regulating assembly includes a regulating shaft assembled on the fixing frame. One end of the regulating shaft is fixedly connected with the movable frame. A regulating handle and a limiting plate are fixedly installed on the regulating shaft, and limiting grooves are formed on the limiting plate and are distributed at equal intervals in a ring shape.

[0028] As a further description of the above technical solution: Through the arrangement of the regulating assembly and the limiting assembly, the discharging angle of the discharging port at the bottom of the lower tank body is adjusted, which is convenient for angle adjustment according to requirements, and thus its applicability is improved.

[0029] Further, the limiting assembly includes a fixing plate fixedly assembled on the fixing frame. A movable rod is slidably installed on the fixing plate, and the upper end of the movable rod is located in the limiting groove of the limiting plate. The lower end of the movable rod is fixedly installed with a movable bottom plate convenient for stepping on with the foot, and a support spring is sleeved on the outer periphery of the movable rod and above the fixing plate.

[0030] As a further description of the above technical solution: The elastic force of the support spring pushes the movable rod upward, and the upper end of the movable rod just engages in the limiting groove of the limiting plate, realizing the angle locking of the limiting plate and the lower tank body.

[0031] Further, a plurality of stirring impellers are fixedly assembled on the inner wall of the lower tank body and are evenly distributed in a ring shape. A first feed hopper for feeding construction raw materials is fixedly assembled on one side of the upper tank body. A water inlet pump is fixedly assembled on the side of the upper tank body away from the first feed hopper. A discharging port for discharging materials is fixedly arranged at the bottom of the lower tank body;

[0032] Wherein, a block mold for manufacturing building blocks is provided below the lower tank body, and the stirred material is poured into the block mold along the discharge port through the lower tank body and formed.

[0033] As a further description of the above technical solution: while the lower tank body rotates, it drives the stirring impeller to perform stirring operations on the raw materials. Finally, the mixed material is discharged along the discharge port, and the material is poured into the block mold. After completion, the block mold is moved to a designated area and waits for molding, so that building blocks for construction can be obtained.

[0034] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0035] 1. For the prefabricated building block manufacturing device based on building waste recycling, through the setting of the screening component and the drying component, the screening speed of the concrete material can be accelerated through the screening pipe, the screening efficiency of the concrete material can be improved, and at the same time, the drying treatment of the concrete material containing moisture is realized. The uniform impeller drives the hot air flow to blow to each corner of the inner cavity of the screening component, effectively heating the screening pipe in all directions without heating dead corners, avoiding the possibility that the material adheres to the inner wall of the screening pipe due to moisture and causing material blockage, and further improving the screening efficiency of the concrete material.

[0036] 2. For the prefabricated building block manufacturing device based on building waste recycling, through the setting of the screening component, the drying component and the hitting component, the hot air flow drives the hitting component to generate a vibration frequency, and the elastic rope driven by the vibration drives the hitting ball to hit the outer wall of the screening pipe, so that the screening pipe and even the screening component synchronously generate a vibration frequency, and the concrete material and the screening pipe are separated from each other by the acting force during vibration, further accelerating the screening effect of the concrete material flow.

[0037] 3. For the prefabricated building block manufacturing device based on building waste recycling, through the setting of the crushing component, the first driving mechanism is driven to drive the crushing teeth to crush the concrete waste. And when the concrete material is crushed sufficiently, the smaller concrete material particles will pass through the filtering holes on the filter plate and continue to fall downward and enter the next screening process. And when the concrete material is not crushed sufficiently, the rotating crushing teeth can be used to crush its particles again, so as to achieve repeated crushing of the insufficiently crushed concrete waste, thereby ensuring the uniformity of the discharged concrete material, improving the crushing effect of the concrete waste, and being beneficial to the secondary utilization of the concrete waste.

[0038] 4. The assembled building block manufacturing device based on the recycling of construction waste can pour materials into the block mold through the setting of the mixing tank assembly and the block mold. After completion, the block mold is moved to a designated area to wait for molding, thereby obtaining building blocks for construction. Through this setting, concrete waste can be reused, and the technology of using construction waste to provide materials for building blocks is realized, thereby reducing the production cost of the manufacturer.

[0039] 5. The prefabricated building block manufacturing device based on the recycling of construction waste realizes the adjustment of the discharge angle of the discharge port at the bottom of the lower tank body by setting the adjustment component and the limit component, which facilitates the angle adjustment according to the needs, thereby improving its applicability.

[0066] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0067] Please refer to Figure 1 、 Figures 10 to 14, An assembly building block manufacturing device based on the reuse of construction waste, including a fixed frame 10, and a movable frame 11 movably arranged on the fixed frame 10. It also includes a mixing tank assembly 12 arranged on the movable frame 11 for mixing concrete materials, a crushing assembly 20 arranged on the mixing tank assembly 12 for crushing concrete waste, a screening assembly 30 arranged in the crushing assembly 20 for filtering and screening the materials after crushing the concrete waste, and a drying assembly 40 for drying the materials containing moisture; The screening assembly 30 includes a screening component 31 with an inner cavity opened inside. A number of sieve pipes 32 that are fixedly assembled in the screening component 31 and are arranged at equal intervals for filtering and screening the materials after crushing the concrete waste; A number of longitudinally equally spaced striking components 60 are arranged inside the screening component 31, and the striking components 60 are located between the sieve pipes 32. A number of uniform impellers 50 are arranged on the inner wall of the screening component 31 on the side facing the drying assembly 40. The drying air flow produced by the operation of the drying assembly 40 is transported into the inner cavity of the screening component 31, while drying the materials containing moisture flowing through the sieve pipes 32, and the drying air flow blows the striking components 60 to make the striking components 60 generate their own vibration frequency. At the same time, the striking components 60 are used to knock on the sieve pipes 32 to make the sieve pipes 32 generate a vibration effect. Through the setting of the screening assembly 30 and the drying assembly 40, the screening speed of the concrete materials can be accelerated through the sieve pipes 32, the screening efficiency of the concrete materials can be improved, and at the same time, the drying treatment of the concrete materials containing moisture is realized. The uniform impellers 50 drive the hot air flow to blow to every corner of the inner cavity of the screening component 31, effectively heating the sieve pipes 32 in all directions, without heating dead corners, avoiding the possibility that the materials adsorb on the inner wall of the sieve pipes 32 due to containing moisture and causing material blockage, and further improving the screening efficiency of the concrete materials.

[0068] Please refer to Figures 6 to 9, the crushing assembly 20 includes a crushing base 21 fixedly assembled on the upper tank body 121. A crushing shell 22 is fixedly assembled on the upper side of the crushing base 21. A second feed hopper 23 for feeding concrete waste is fixedly installed on the upper side of the crushing shell 22. A first driving mechanism 24 is provided on the front side of the crushing base 21. A gear set 25 is provided on the front side of the crushing shell 22, and the gear set 25 includes two meshing gears. Two crushing teeth 26 are arranged inside the crushing shell 22. The output end of the first driving mechanism 24 drives the two gears of the gear set 25 to mesh and drive each other, and makes the two crushing teeth 26 rotate relatively to crush the concrete waste; a plurality of auxiliary plates 27 are arranged at equal intervals on the inner wall of the crushing shell 22, and the auxiliary plates 27 are installed in cooperation with the crushing teeth 26. A filter plate 28 for filtering the materials after crushing the concrete waste is arranged inside the crushing shell 22 and directly below the crushing teeth 26. By driving the first driving mechanism 24 to drive the crushing teeth 26 to crush the concrete waste, when the concrete material is crushed sufficiently, the smaller concrete material particles will pass through the filter holes on the filter plate 28 and continue to fall downward and enter the next sieving process. When the concrete material is not crushed sufficiently, the rotating crushing teeth 26 can be used to crush its particles again, so as to achieve repeated crushing of the insufficiently crushed concrete waste, thereby ensuring the uniformity of the discharged concrete material, improving the crushing effect of the concrete waste, and being beneficial to the secondary utilization of the concrete waste.

[0069] Please refer to Figures 10 to 12 , the drying assembly 40 includes a dryer 41 fixedly assembled on the side of the crushing assembly 20. One side of the dryer 41 close to the crushing assembly 20 is fixedly connected to the transmission part 42 through an air inlet pipe 411. An air vent groove 421 for the flow of hot air is opened inside the transmission part 42. The side of the transmission part 42 away from the air inlet pipe 411 is fixedly connected and communicated with the screening component 31. The hot air generated by the dryer 41 is transmitted along the air vent groove 421 of the transmission part 42 into the inner cavity of the screening component 31, and the uniform impeller 50 is used to drive the hot air to blow to all corners of the inner cavity of the screening component 31, effectively heating the sieve tube 32 in all directions, so as to dry the concrete material containing moisture.

[0070] Please refer to Figures 11 to 14 , the sieve tube 32 includes a drying section 321 and an accelerating section 322. The inner diameter of the drying section 321 is larger than that of the accelerating section 322. Since the inner diameter of the drying section 321 is larger than that of the accelerating section 322, when the material passes through the smaller inner diameter in the middle of the accelerating section 322, the cross-sectional area of the accelerating section 322 becomes smaller, and the flow rate of the material will increase, thereby improving the screening speed of the concrete material.

[0071] Please refer to Figures 12 to 14, the striking assembly 60 includes an elastic cord 61. The front and rear ends of the elastic cord 61 are fixedly connected to the inner cavity wall of the screening component 31. A number of vibration plates 62 and striking balls 63 are arranged at equal intervals on the elastic cord 61, and the vibration plates 62 and the striking balls 63 are arranged in sequence. Among them, the striking balls 63 are located between the screening pipes 32. The hot air flow drives the striking assembly 60 to generate a vibration frequency, and the vibrating elastic cord 61 drives the striking balls 63 to strike the outer wall of the screening pipes 32, so that the screening pipes 32 and even the screening component 31 generate a vibration frequency synchronously, and the concrete material is separated from the screening pipes 32 by the acting force during vibration, accelerating the screening effect of the concrete material flow.

[0072] Please refer to Figures 3 to 5 , the mixing tank assembly 12 includes an upper tank body 121 and a lower tank body 122. The movable frame 11 is rotatably connected to the bottom of the lower tank body 122 through a movable shaft 111, and the movable frame 11 is fixedly connected to the outer side wall of the upper tank body 121 through a fixed shaft 112. An outer ring sleeve 13 is fixedly assembled on the inner wall of the upper tank body 121, and a chute 131 is opened on the inner wall of the outer ring sleeve 13. An inner ring sleeve 14 is fixedly assembled on the inner wall of the lower tank body 122, and a slider 141 corresponding to the chute 131 is fixedly arranged on the outer wall of the inner ring sleeve 14. The slider 141 is located in the chute 131. The upper tank body 121 and the lower tank body 122 are rotationally installed through the outer ring sleeve 13 and the inner ring sleeve 14. When the lower tank body 122 rotates, the inner ring sleeve 14 is driven to rotate synchronously, and the slider 141 is driven to slide synchronously in the chute 131 of the outer ring sleeve 13, so as to achieve the effect that the lower tank body 122 rotates and stirs itself while the upper tank body 121 remains stationary.

[0073] Please refer to Figures 1 to 3 , a mixing assembly 70 for driving the lower tank body 122 is provided on the outer side of the fixed frame 10. The mixing assembly 70 includes a housing fixedly assembled on the fixed frame 10, and a second driving mechanism 71 is fixedly arranged inside the housing. The output end of the second driving mechanism 71 is fixedly connected to a driving gear 72. The mixing assembly 70 further includes a fixed gear ring 73 fixedly assembled on the outer periphery of the lower tank body 122. The driving gear 72 is meshed with the fixed gear ring 73. The second driving mechanism 71 drives the driving gear 72 to rotate, and the meshing action between the driving gear 72 and the fixed gear ring 73 drives the lower tank body 122 to rotate itself, and the lower tank body 122 rotates to stir the raw materials.

[0074] Please refer to Figure 1 , Figure 15An adjusting component 80 for adjusting the steering of the stirring tank component 12 and a limiting component 90 for limiting the steering angle of the stirring tank component 12 are provided on the side of the fixed frame 10 away from the stirring component 70; the adjusting component 80 includes an adjusting shaft 81 assembled on the fixed frame 10, one end of the adjusting shaft 81 is fixedly connected to the movable frame 11, an adjusting handle 82 and a limiting plate 83 are fixedly mounted on the adjusting shaft 81, and the limiting plate 83 is provided with limiting grooves 831 equidistantly distributed in an annular shape. By setting the adjusting component 80 and the limiting component 90, the discharge angle of the discharge port 18 at the bottom of the lower tank body 122 is adjusted, so that it is convenient to adjust the angle according to needs.

[0075] Please refer to Figure 15 The limit assembly 90 includes a fixed plate 91 fixedly assembled on the fixed frame 10, and a movable rod 92 is slidably installed on the fixed plate 91, and the upper end of the movable rod 92 is located in the limiting groove 831 of the limiting plate 83, and the lower end of the movable rod 92 is fixedly installed with a movable bottom plate 93 convenient for stepping on. The outer periphery of the movable rod 92 and the upper side of the fixed plate 91 are sleeved with a supporting spring 94. By pressing the movable bottom plate 93 with the foot, the movable rod 92 is driven to move downward, and the movable rod 92 and the limiting groove 831 of the limiting plate 83 are separated from each other, so that the clamping relationship between the movable rod 92 and the limiting plate 83 is released, and when it is rotated to a suitable angle, the staff releases the foot again, and the movable rod 92 is pushed upward based on the elastic force of the supporting spring 94, and the upper end of the movable rod 92 is just clamped in the limiting groove 831 of the limiting plate 83, so as to realize the angle locking of the limiting plate 83 and the lower tank body 122.

[0076] Please refer to Figures 1 to 4 The inner wall of the lower tank body 122 is fixedly equipped with a plurality of stirring impellers 15 evenly distributed in an annular shape, a first feed hopper 16 for feeding building raw materials is fixedly equipped on one side of the upper tank body 121, a water inlet pump 17 is fixedly equipped on the side of the upper tank body 121 away from the first feed hopper 16, and a discharge port 18 for material discharge is fixedly provided at the bottom of the lower tank body 122; wherein, a block mold 19 for manufacturing building blocks is provided below the lower tank body 122, and the stirred materials are poured into the lower tank body 122 along the discharge port 18. The raw materials are mixed and formed in the block mold 19, and the stirring impeller 15 is driven to stir the raw materials by rotating the lower tank body 122. The driving force when the stirring impeller 15 contacts the raw materials promotes the raw materials to move and mix, which can effectively prevent the raw materials from piling up separately, thereby greatly improving the mixing efficiency. Finally, the mixed materials are discharged from the discharge port 18 and poured into the block mold 19. After completion, the block mold 19 is moved to the designated area to wait for molding, thereby obtaining building blocks for construction.

[0077] The specific usage and function of this embodiment are as follows:

[0078] Working principle: When in use, the concrete waste is poured along the second feed hopper 23 and slides down along the inner wall of the second feed hopper 23. The first driving mechanism 24 is started through the control switch. The first driving mechanism 24 drives the gear set 25 to rotate, causing the two gears in the gear set 25 to mesh and rotate with each other. While the gear set 25 is rotating, it drives the crushing teeth 26 to rotate relatively synchronously, causing the two crushing teeth 26 to mesh with each other and crush the concrete waste. The crushed concrete material falls downward above the filter plate 28. When the concrete material is crushed sufficiently, the smaller concrete material particles will pass through the filter holes on the filter plate 28 and continue to fall downward and enter the next screening process, while the larger particles above the filter plate 28 remain above it. At the same time, the rotating crushing teeth 26 crush their particles again, so that the larger concrete material particles above can be secondarily crushed, thereby achieving repeated crushing of the inadequately crushed concrete waste, ensuring the uniformity of the discharged concrete material, improving the crushing effect of the concrete waste, and being beneficial to the secondary utilization of the concrete waste;

[0079] After the concrete waste is crushed by the crushing teeth 26, the material falls downward onto the screening component 31. At the same time, the material falls downward along the screening pipe 32 into the lower tank body 122. Since a drying section 321 is provided in the screening pipe 32 and the inner diameter of the drying section 321 is larger than that of the acceleration section 322, when the material passes through the smaller inner diameter of the middle of the acceleration section 322, the cross-sectional area of the acceleration section 322 becomes smaller, and the flow rate of the material will increase, thereby improving the screening speed of the concrete material and effectively improving the screening efficiency of the concrete material. And while the concrete material passes through the screening pipe 32, through the control of the control switch, the dryer 41 is driven to generate kinetic energy and operate synchronously. The dryer 41 transmits the generated hot air flow along the ventilation slots 421 of the transmission part 42 into the inner cavity of the screening component 31, and uses the acting force when the hot air flow flows to drive the uniform impeller 50 to rotate. The uniform impeller 50 drives the hot air flow to blow to all corners of the inner cavity of the screening component 31, effectively heating the screening pipe 32 in all directions, and conducting the heat on the screening pipe 32 to the inner wall of the screening pipe 32, thereby drying the concrete material containing moisture. There will be no heating dead angle, effectively strengthening the drying effect on the material, and avoiding the possibility of the material being adsorbed on the inner wall of the screening pipe 32 due to moisture content and causing material blockage, further improving the screening efficiency of the concrete material;

[0080] In addition, while the uniform impeller 50 drives the hot air flow, the hot air flow is synchronously blown onto the vibration plate 62, and the elastic rope 61 generates a vibration frequency, and the vibrating elastic rope 61 drives the striking ball 63 to strike the outer wall of the screening tube 32, so that the screening tube 32 and even the screening component 31 synchronously generate a vibration frequency, and the force during vibration is used to separate the concrete material from the screening tube 32, further accelerating the screening effect of the concrete logistics, and effectively avoiding the possibility of material blockage;

[0081] After that, the screened concrete material falls downward into the lower tank body 122, and then the cement raw material is poured into the lower tank body 122 through the first feed hopper 16, and water is added thereto by the water inlet pump 17, and the second drive mechanism 71 is driven to drive the driving gear 72 to rotate by the control switch, and the meshing action between the driving gear 72 and the fixed gear ring 73 is used to drive the lower tank body 122 to rotate, and the lower tank body 122 is driven to drive the stirring impeller 15 to stir the raw material while the lower tank body 122 rotates. Based on the driving force when the stirring impeller 15 contacts the raw material, the raw material is pushed to move and mix, and is evenly distributed and spread. Through multiple dispersions and remixing, the raw material can be effectively prevented from being accumulated separately, thereby greatly improving the mixing efficiency;

[0082] Finally, when the material mixing is completed, the mixed material is discharged from the discharge port 18, and the material is poured into the block mold 19. After completion, the block mold 19 is moved to a designated area to wait for molding, thereby obtaining a building block for construction. This arrangement enables the concrete waste to be reused, and realizes the technology of providing materials for building blocks with construction waste, thereby reducing the production cost of the manufacturer.

[0083] In addition, when it is necessary to adjust the angle position of the mixing tank, the staff member drives the movable bottom plate 93 by stepping on the movable bottom plate 93 with his foot to drive the movable rod 92 to move downward, and separate the movable rod 92 from the limiting groove 831 of the limiting plate 83, so that the clamping relationship between the movable rod 92 and the limiting plate 83 is released, and then the adjusting handle 82 is rotated to drive the limiting plate 83 and the mixing tube assembly to move at the same time. When it is rotated to a suitable angle, the staff member releases his foot again, and the movable rod 92 is pushed upward based on the elastic force of the support spring 94, and the upper end of the movable rod 92 is just clamped in the limiting groove 831 of the limiting plate 83, thereby realizing the angle locking of the limiting plate 83 and the lower tank body 122. The discharging angle of the discharge port 18 at the bottom of the lower tank body 122 is synchronously changed through this setting, which is convenient for it to adjust the angle according to needs, thereby improving its applicability.
