Description

Technical Field

[0001] The invention relates to the technical field of permeable brick production, in particular to a blank molding device for producing permeable bricks. Background Art

[0002] Permeable bricks: also called permeable bricks, Dutch bricks, etc., are new green and environmentally friendly building materials. Permeable bricks have good water permeability and strong anti-slip function; natural color and long service life; smooth appearance, clear corners, neat lines; high anti-freeze and salt-alkali resistance; not easy to break, higher compression and flexural strength than similar products, safe driving; low maintenance cost, easy to replace, convenient for underground pipeline burial; various colors and shapes, set off with the surrounding environment, natural and beautiful.

[0003] The existing Chinese patent with publication number CN118024381B discloses a permeable brick production device, but the patent and the prior art also have the following defects: First, the permeable brick is made by mixing and pressing various mineral materials. During the pressing process, the mineral materials are located in the mold cavity. After the pressing process, the mineral materials directly become blocks. Therefore, in the production process of the permeable brick, there is no need to cut the permeable brick. The problem of the mixture cracking easily caused by the splitting and molding of the raw materials proposed in the above patent does not exist; Secondly, when the permeable bricks are pressed traditionally, the mineral materials injected into the mold cavity will spill onto the brick pressing platform. As the production continues, a large amount of loose materials will accumulate on the brick pressing platform, which will not only cause a waste of raw materials, but also the loose materials that are not cleaned in time will affect the normal pressing, resulting in an irregular appearance of the final extruded permeable bricks.

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The permeable brick is made of a mixture of various mineral materials. During the manufacturing process, the mineral materials are pressed twice, first the bottom layer and then the surface layer. The final permeable brick has a layered effect, and the bottom layer of the permeable brick is thicker than the surface layer of the permeable brick, that is, the amount of material used in the surface layer is less than that of the bottom layer. The two feed bins 8 of the device are respectively used to accommodate the bottom layer mineral materials and the surface layer mineral materials. Before production, the No. 1 lifting platform 4 drives a number of pressing blocks 5 to rise, and the No. 2 lifting platform drives a number of supporting blocks 6 to rise. Each supporting block 6 will be inserted upward into the corresponding mold cavity 3. The supporting block 6 is used to support the mineral materials entering the mold cavity 3, and the volume of the injected mold cavity 3 can be changed by controlling the height of the supporting block 6. During production, the translation mechanism 7 drives the two feeding bins 8 to move along the length direction of the brick pressing platform 1 , when the feeding bin 8 containing the bottom layer of mineral material moves to the top of several mold shells 2, the two groups of feeding bins 8 stop moving, and the feeding valve opens several feeding hoppers 9 in the current feeding bin 8, so that the bottom layer of mineral material will be injected into each mold cavity 3. When each mold cavity 3 is filled, the feeding valve closes several feeding hoppers 9 synchronously, and then the translation mechanism 7 continues to drive the two groups of feeding bins 8 to translate. When the two groups of feeding bins 8 pass several mold cavities 3, the No. 1 scraper 10 arranged between the two groups of feeding bins 8 will scrape the bottom layer of mineral material in each mold cavity 3 flat. At the same time, as the feeding bin 8 translates, the No. 1 scraper 10 will also scrape the excess bottom layer of mineral material to the corresponding return mechanism. In the process of the No. 1 scraper 10 driving towards the return mechanism, the horizontal scraping mechanism will be carried by the No. 1 scraper 10 The bottom mineral materials are concentratedly scraped to one side, and finally when the No. 1 scraper 10 drives out of the brick pressing platform 1, the No. 1 scraper 10 will scrape the concentrated bottom mineral materials into the collecting hopper 11, and then the vertical spiral feeding mechanism 12 will inject the bottom mineral materials into the corresponding feeding bin 8 again. When the bottom mineral materials are returned through the return mechanism, the No. 1 lifting platform 4 drives a number of pressing blocks 5 to descend. During this process, each pressing block 5 will be pressed into the corresponding mold cavity 3, so that the bottom mineral materials will be squeezed into the bottom mineral blocks by the pressing blocks 5 and the supporting blocks 6 in the mold cavity 3. When the bottom mineral blocks are formed, the No. 2 lifting platform drives a number of supporting blocks 6 to descend a certain distance, so that the top of the bottom mineral blocks is not flush with the top of the brick pressing platform 1, thereby forming a bottom mineral block with a In the cavity for accommodating the surface mineral material, the translation mechanism 7 will then drive the two groups of feeding bins 8 to translate in the opposite direction. During this process, the feeding bin 8 containing the surface mineral material will translate toward the plurality of mold cavities 3. When the feeding bin 8 containing the surface mineral material is moved to the top of the plurality of mold cavities 3, the feeding valve will open the corresponding plurality of feeding hoppers 9. At this time, the surface mineral material will be injected downward into the plurality of mold cavities 3. When the mold cavities 3 are filled, the feeding valve will close the corresponding plurality of feeding hoppers 9. The translation mechanism 7 will drive the two groups of feeding bins 8 to continue to translate. During this process, the No. 1 scraper 10 will scrape the surface mineral material in the mold cavity 3 flat. At the same time, as the two groups of feeding bins 8 translate, the No. 1 scraper 10 will also scrape the excess surface mineral material to the corresponding return mechanism. When the surface mineral material is scraped away by the No. 1 scraper 10,The horizontal scraping mechanism will scrape the surface mineral materials to one side, and finally the surface mineral materials will be scraped into the corresponding collecting hopper 11. When the surface mineral materials fall into the collecting hopper 11, the corresponding spiral feeding mechanism 12 will re-inject the surface mineral materials in the collecting hopper 11 into the corresponding feeding bin 8. When the surface mineral materials are returned, the No. 1 lifting platform 4 will drive several pressing blocks 5 to press the surface mineral materials in several mold cavities 3 downward to form, and finally obtain a layered permeable brick. When the permeable brick is formed, the No. 2 lifting platform will drive several supporting blocks 6 to rise, so that each permeable brick is lifted out of the corresponding mold cavity 3, and then the formed permeable brick can be taken away by an external mechanical transfer arm (not shown in the figure).

[0022] In order to show the specific structure of the No. 2 lifting platform, the following features are set: The No. 2 lifting platform includes a pressing plate 13, a lifting plate 14 and an elastic buffer. The lifting plate 14 is horizontal. The pressing plate 13 is horizontally arranged directly above the lifting plate 14. The elastic buffer includes a number of No. 1 springs 15 arranged between the pressing plate 13 and the lifting plate 14. Each No. 1 spring 15 is vertical. The two ends of each No. 1 spring 15 are respectively connected to the bottom of the pressing plate 13 and the top of the lifting plate 14. A number of vertically upward limit pins 16 are formed on the top of the lifting plate 14. A number of No. 1 limit sleeves 17 are formed on the pressing plate 13. Each limit pin 16 passes upward through the corresponding No. 1 limit sleeve 17. A number of support blocks 6 are fixed to the top of the pressing plate 13.

[0023] The lifting plate 14 is used to drive the several supporting blocks 6 on the pressure plate 13 to rise and fall. When the pressure block 5 squeezes the mineral material in the mold cavity 3 downward, the punching force of the pressure block 5 is buffered by the No. 1 spring 15 arranged between the pressure plate 13 and the lifting plate 14. During this process, the pressure plate 13 will drop slightly and squeeze the No. 1 spring 15, so that the No. 1 spring 15 generates elastic force. When the pressure block 5 rises, the No. 1 spring 15 will drive the pressure plate 13 to rise and reset through the elastic force. The limit pin 16 passing through the No. 1 limit sleeve 17 is used to limit the displacement of the pressure plate 13 to prevent the pressure plate 13 from deviating left and right.

[0024] In order to show how the lifting plate 14 is raised and lowered, the following features are provided: A fixed base 18 is provided below the lifting plate 14, and a plurality of groups of vertical hydraulic cylinders 19 are provided on the fixed base 18. The piston rods of each group of hydraulic cylinders 19 are fixedly connected upward to the bottom of the lifting plate 14. A plurality of groups of vertical fixed rods 20 are also provided on the fixed base 18. A plurality of No. 2 limiting sleeves 21 are provided on the lifting plate 14, and each fixed rod 20 passes through the corresponding No. 2 limiting sleeve 21 upward.

[0025] Several groups of hydraulic cylinders 19 work synchronously, and the lifting plate 14 is driven to rise and fall by the hydraulic cylinders 19. When the pressing block 5 descends to squeeze the mineral material in the mold cavity 3, the hydraulic cylinders 19 are used to give the lifting plate 14 an upward hydraulic pressure to prevent the lifting plate 14 from descending due to the pressure of the pressing block 5. The fixing rod 20 passing through the No. 2 limit sleeve 21 is used to improve the stability of the displacement of the lifting plate 14. In actual use, a gantry (not shown in the figure) is provided above the brick pressing platform 1, and a lifting system (not shown in the figure) is provided on the gantry for driving the No. 1 lifting platform 4 to rise and fall.

[0026] In order to show the specific structure of each group of feeding bins 8, the following features are set: Each group of feeding bins 8 includes a strip-shaped housing 22 and a spiral feeding mechanism 23. The strip-shaped housing 22 is horizontal (eg Fig.13 As shown in the figure, the top of the strip housing 22 is an open structure, the spiral feeding mechanism 23 includes a No. 1 columnar tube 24, a No. 1 rotating shaft 25 and a No. 1 spiral blade 26, the strip housing 22 is arranged on the translation mechanism 7, the No. 1 columnar tube 24 is horizontally fixed in the strip housing 22, both ends of the No. 1 columnar tube 24 are closed structures, the No. 1 rotating shaft 25 is horizontally rotated in the No. 1 columnar tube 24, the No. 1 spiral blade 26 is fixedly connected to the No. 1 rotating shaft 25, and the No. 1 spiral blade 26 is rotated along the axial direction of the No. 1 rotating shaft 25. The strip-shaped outer shell 22 is extended in rotation, and one end of the strip-shaped outer shell 22 is fixedly provided with a No. 1 motor 27 connected with a No. 1 rotating shaft 25; a vertically upward feeding pipe 28 is fixedly provided on the outer wall of one end of the No. 1 columnar tube 24; a plurality of feeding hoppers 9 are equidistantly distributed below the No. 1 columnar tube 24 along the axial direction of the No. 1 columnar tube 24; each feeding hopper 9 is connected with the No. 1 columnar tube 24; a plurality of leakage holes 29 corresponding to the feeding hoppers 9 are provided at the bottom of the strip-shaped outer shell 22; and each feeding valve is provided at the bottom of the strip-shaped outer shell 22.

[0027] Mineral material is injected into the No. 1 columnar tube 24 through the feed pipe 28. The two No. 1 columnar tubes 24 are used to accommodate the bottom layer of mineral material and the surface layer of mineral material respectively. Before the mineral material is injected into the No. 1 columnar tube 24, the feed valve synchronously blocks several feed hoppers 9. When the mineral material is injected into the No. 1 columnar tube 24, the No. 1 motor 27 is started, and the No. 1 motor 27 will drive the No. 1 rotating shaft 25 to rotate, so that the No. 1 spiral blade 26 will drive the mineral material in the No. 1 columnar tube 24 to move along the axial direction of the No. 1 columnar tube 24. During this process, the mineral material will fall into several feed hoppers 9 in turn. The No. 1 spiral blade 26 can ensure that each feed hopper 9 can be filled with mineral material, thereby preventing the occurrence of inconsistent amounts of mineral material in each mold cavity 3 when the mineral material is subsequently injected into the mold cavity 3.

[0028] In order to show the specific structure of the translation mechanism 7, the following features are set: Support frames 30 are fixed on both sides of the brick pressing platform 1, and the translation mechanism 7 includes two groups of symmetrical electrically driven displacement parts, each group of electrically driven displacement parts includes a slide rail 31 and a plurality of electric sliders 32, the slide rail 31 is horizontally fixed on the corresponding support frame 30, each electric slider 32 slides on the corresponding slide rail 31, and a bracket 33 is provided between the two slide rails 31 and is horizontally mounted on the two groups of electric sliders 32, and each group of strip-shaped housings 22 is fixed on the bracket 33.

[0029] The two groups of electric sliders 32 are displaced synchronously, and the displacement of the electric sliders 32 drives the entire bracket 33 to translate. When the bracket 33 is displaced, the two groups of strip shells 22 arranged on the bracket 33 will translate synchronously, and finally the synchronous translation of the two groups of feed bins 8 is realized.

[0030] In order to show the specific structure of the feed valve, the following features are set: Each material passing valve includes a strip valve plate 34 and an elastic member. A strip slide groove 35 is formed at the bottom of each strip shell 22. The length direction of the strip slide groove 35 is parallel to the axial direction of the No. 1 columnar tube 24. The strip valve plate 34 slides in the strip slide groove 35. The strip valve plate 34 is provided with through holes 36 whose number is consistent with the leakage holes 29. The elastic member is arranged at one end of the strip valve plate 34. The elastic member is used to drive the strip valve plate 34 to translate so that several through holes 36 are misaligned with the leakage holes 29. The end of the strip valve plate 34 away from the elastic member is formed with a vertical downward standing plate 37. One of the support frames 30 is fixed with several horizontal cylinders 38.

[0031] When processing the mold cavities 3 on the brick pressing platform 1, the plurality of mold cavities 3 are evenly divided into two groups along the length direction of the brick pressing platform 1 (eg Figure 4 As shown in the figure, the number of cylinders 38 on the support frame 30 is consistent with the number of groups of mold cavities 3. Taking the present device as an example, since the mold cavities 3 on the brick pressing platform 1 are divided into two groups, the number of cylinders 38 on the support frame 30 is also two. When the strip housing 22 translates to the top of a corresponding group of mold cavities 3, the output end of one of the cylinders 38 extends out and drives the strip valve plate 34 to translate toward the elastic member by contacting the vertical plate 37. During this process, a plurality of through holes 36 will gradually correspond to a plurality of leakage holes 29. At the same time, the elastic member will generate a reset elastic force. When the through hole 36 corresponds to the leakage hole 29, the mineral material in the feed hopper 9 will be discharged downward through the leakage hole 29 and the through hole 36 in turn, and finally the mineral material will be injected into the corresponding mold cavity 3. When the mold cavity 3 is filled with the mineral material, the output end of the cylinder 38 retracts. At this time, the elastic member will drive the strip valve plate 34 to move in the opposite direction until it is reset. After the strip valve plate 34 is reset, several through holes 36 and several leakage holes 29 are misaligned again. When one group of mold cavities 3 is injected with mineral material, the strip shell 22 is translated to the next group of mold cavities 3 for injection.

[0032] In order to show the specific structure of the elastic part, the following features are set: The elastic member includes a guide pin 39, a No. 2 spring 40 and a fixed plate 41. A baffle 42 is formed vertically downward at one end of the strip valve plate 34 away from the vertical plate 37. The fixed plate 41 is vertically arranged at the bottom of the strip shell 22, and the fixed plate 41 is located next to the baffle 42. The guide pin 39 is horizontally fixed to the baffle 42, and the guide pin 39 passes through the fixed plate 41. The No. 2 spring 40 is sleeved on the guide pin 39, and the two ends of the No. 2 spring 40 are respectively in conflict with the fixed plate 41 and the baffle 42.

[0033] In the initial state, the second spring 40 releases its elastic force to drive the strip valve plate 34 to move. When the strip valve plate 34 moves, a plurality of leakage holes 29 will be misaligned with a plurality of through holes 36. Thereafter, the baffle plate 42 will conflict with the strip slide groove 35 to limit the displacement stroke of the strip valve plate 34, so that the strip valve plate 34 stops in the current state. At this time, the strip valve plate 34 will block a plurality of leakage holes 29. When the strip housing 22 is translated to the top of one group of mold cavities 3, the output end of the cylinder 38 will extend. After that, the strip valve plate 34 is driven by the cylinder 38 to translate toward the fixed plate 41. During this process, the baffle 42 will compress the No. 2 spring 40, so that the No. 2 spring 40 generates elastic force. At the same time, a number of leakage holes 29 will correspond to a number of through holes 36, and finally the mineral material in the feed hopper 9 will be discharged downward. When the mineral material in the mold cavity 3 is filled, the output end of the cylinder 38 retracts. At this time, the No. 2 spring 40 drives the strip valve plate 34 to reset through the elastic force until the baffle 42 conflicts with the strip slide groove 35 again.

[0034] In order to show the specific structure of the transverse scraping mechanism, the following features are set: A horizontal connecting plate 43 is fixed between the two strip-shaped housings 22, and the first scraper 10 is fixed to the bottom of the connecting plate 43 (such as Fig.10 As shown), the lower end of the No. 1 scraper 10 is fitted with the top of the brick pressing platform 1, and each horizontal scraping mechanism includes a No. 2 scraper 44, a threaded rod 45, a limit rod 46 and a driving member. The limit rod 46 is horizontally fixed on the side wall of the No. 1 scraper 10, the threaded rod 45 is parallel to the limit rod 46, and the threaded rod 45 rotates on the side wall of the No. 1 scraper 10. The No. 2 scraper 44 is vertically arranged beside the No. 1 scraper 10. A guide sleeve 47 and a threaded sleeve 48 are fixed on the No. 2 scraper 44. The guide sleeve 47 is sleeved on the limit rod 46, and the threaded sleeve 48 is sleeved on the threaded rod 45. The threaded sleeve 48 is threadedly matched with the threaded rod 45, and the driving member is arranged on the threaded rod 45.

[0035] When the scraper No. 1 10 is scraping away the excess mineral material on the brick pressing platform 1, the driving part will drive the threaded rod 45 to rotate. Through the cooperation of the threaded sleeve 48 and the threaded rod 45, the scraper No. 2 44 will translate along the axial direction of the limiting rod 46. At this time, the scraper No. 2 44 will concentrate the mineral material next to the scraper No. 1 10 to one side, and finally ensure that the scraper No. 2 44 can scrape the concentrated distributed mineral material into the collecting hopper 11.

[0036] In order to show the specific structure of the drive, the following features are set: The driving member includes two driving wheels 49, each of which is provided with a rubber ring 50 on its peripheral wall, and wheel tracks for the driving wheels 49 to run on are provided on both sides of the brick pressing platform 1, and each set of wheel tracks includes two sets of symmetrical strip plates 51, and each set of strip plates 51 is horizontally fixed to the brick pressing platform 1, and the two sets of strip plates 51 are spaced apart along the length direction of the brick pressing platform 1.

[0037] The two groups of strip plates 51 are symmetrical about the position where the mold cavity 3 is provided on the brick pressing platform 1 (eg Figure 4 As shown in the figure), when the first scraper 10 is in the part where the mold cavity 3 is provided on the brick pressing platform 1, the driving wheel 49 will not contact the strip plate 51. When the strip housing 22 drives the first scraper 10 away from the mold cavity 3, the two driving wheels 49 will move to the two strip plates 51 respectively. When the driving wheels 49 walk on the strip plates 51, the driving wheels 49 will rotate, so that the driving wheels 49 will drive the threaded rod 45 to rotate, and finally the second scraper 44 will translate to move the side of the first scraper 10 The mineral materials are scraped to one side. When the strip shell 22 is displaced in the reverse direction, the driving wheel 49 will move in the reverse direction on the strip plate 51. At this time, the driving wheel 49 will drive the threaded rod 45 to rotate in the reverse direction. Finally, the No. 2 scraper 44 will be displaced in the reverse direction to reset. In summary, when the No. 1 scraper 10 is close to the mold cavity 3, the No. 2 scraper 44 will not be displaced. When the No. 1 scraper 10 is away from the mold cavity 3, the No. 2 scraper 44 will move horizontally, and the mineral materials beside the No. 1 scraper 10 will always be scraped to the same side by the No. 2 scraper 44.

[0038] In order to show the specific structure of the screw feeding mechanism 12, the following features are set: Each collecting hopper 11 is fixed to the end of the brick pressing platform 1 through a No. 1 mounting frame 52, and each spiral feeding mechanism 12 includes a No. 2 columnar tube 53, a No. 2 rotating shaft 54 ​​and a No. 2 spiral blade 55. The No. 2 columnar tube 53 is vertical and fixed to the side of the collecting hopper 11 through a No. 2 mounting frame 56. Both ends of the No. 2 columnar tube 53 are closed structures. The No. 2 rotating shaft 54 ​​rotates vertically in the No. 2 columnar tube 53. The No. 2 spiral blade 55 is fixedly connected to the No. 2 rotating shaft 54, and the No. 2 spiral blade 55 extends in an axial spiral direction of the No. 2 rotating shaft 54. A No. 2 motor 57 connected to the No. 2 rotating shaft 54 ​​is fixedly provided below the No. 2 columnar tube 53. A filling pipe 58 connected to the collecting hopper 11 is provided on the outer wall of the lower end of the No. 2 columnar tube 53, and a discharge pipe 59 inclined downward is provided on the outer wall of the upper end of the No. 2 columnar tube 53.

[0039] When the strip shell 22 translates to the top of the collecting hopper 11, the scraper No. 1 10 will scrape the mineral material on the brick pressing platform 1 into the collecting hopper 11, and the mineral material falling into the collecting hopper 11 will enter the lower end of the No. 2 columnar tube 53 through the injection pipe 58. At this time, the No. 2 motor 57 is started, and the No. 2 motor 57 will drive the No. 2 spiral blade 55 to rotate through the No. 2 rotating shaft 54, so that the No. 2 spiral blade 55 will drive the mineral material in the No. 2 columnar tube 53 to move upward, and finally the mineral material in the No. 2 columnar tube 53 will be discharged downward into the corresponding feed pipe 28 through the discharge pipe 59, wherein the two collecting hoppers 11 respectively contain the bottom layer of mineral material and the surface layer of mineral material, so that the excess bottom layer of mineral material and surface layer of mineral material on the brick pressing platform 1 will return to the two groups of No. 1 columnar tubes 24 respectively.

[0040] Working principle: The permeable brick is made of a mixture of various mineral materials. During the manufacturing process, the mineral materials are pressed twice, first the bottom layer and then the surface layer. The final permeable brick has a layered effect, and the bottom layer of the permeable brick is thicker than the surface layer of the permeable brick, that is, the amount of material used in the surface layer is less than that of the bottom layer. The two feed bins 8 of the device are respectively used to accommodate the bottom layer mineral materials and the surface layer mineral materials. Before production, the No. 1 lifting platform 4 drives a number of pressing blocks 5 to rise, and the No. 2 lifting platform drives a number of supporting blocks 6 to rise. Each supporting block 6 will be inserted upward into the corresponding mold cavity 3. The supporting block 6 is used to support the mineral materials entering the mold cavity 3, and the volume of the injected mold cavity 3 can be changed by controlling the height of the supporting block 6. During production, the translation mechanism 7 drives the two feeding bins 8 to move along the length direction of the brick pressing platform 1 , when the feeding bin 8 containing the bottom layer of mineral material moves to the top of several mold shells 2, the two groups of feeding bins 8 stop moving, and the feeding valve opens several feeding hoppers 9 in the current feeding bin 8, so that the bottom layer of mineral material will be injected into each mold cavity 3. When each mold cavity 3 is filled, the feeding valve closes several feeding hoppers 9 synchronously, and then the translation mechanism 7 continues to drive the two groups of feeding bins 8 to translate. When the two groups of feeding bins 8 pass several mold cavities 3, the No. 1 scraper 10 arranged between the two groups of feeding bins 8 will scrape the bottom layer of mineral material in each mold cavity 3 flat. At the same time, as the feeding bin 8 translates, the No. 1 scraper 10 will also scrape the excess bottom layer of mineral material to the corresponding return mechanism. In the process of the No. 1 scraper 10 driving towards the return mechanism, the horizontal scraping mechanism will be carried by the No. 1 scraper 10 The bottom mineral materials are concentratedly scraped to one side, and finally when the No. 1 scraper 10 drives out of the brick pressing platform 1, the No. 1 scraper 10 will scrape the concentrated bottom mineral materials into the collecting hopper 11, and then the vertical spiral feeding mechanism 12 will inject the bottom mineral materials into the corresponding feeding bin 8 again. When the bottom mineral materials are returned through the return mechanism, the No. 1 lifting platform 4 drives a number of pressing blocks 5 to descend. During this process, each pressing block 5 will be pressed into the corresponding mold cavity 3, so that the bottom mineral materials will be squeezed into the bottom mineral blocks by the pressing blocks 5 and the supporting blocks 6 in the mold cavity 3. When the bottom mineral blocks are formed, the No. 2 lifting platform drives a number of supporting blocks 6 to descend a certain distance, so that the top of the bottom mineral blocks is not flush with the top of the brick pressing platform 1, thereby forming a bottom mineral block with a In the cavity for accommodating the surface mineral material, the translation mechanism 7 will then drive the two groups of feeding bins 8 to translate in the opposite direction. During this process, the feeding bin 8 containing the surface mineral material will translate toward the plurality of mold cavities 3. When the feeding bin 8 containing the surface mineral material is moved to the top of the plurality of mold cavities 3, the feeding valve will open the corresponding plurality of feeding hoppers 9. At this time, the surface mineral material will be injected downward into the plurality of mold cavities 3. When the mold cavities 3 are filled, the feeding valve will close the corresponding plurality of feeding hoppers 9. The translation mechanism 7 will drive the two groups of feeding bins 8 to continue to translate. During this process, the No. 1 scraper 10 will scrape the surface mineral material in the mold cavity 3 flat. At the same time, as the two groups of feeding bins 8 translate, the No. 1 scraper 10 will also scrape the excess surface mineral material to the corresponding return mechanism. When the surface mineral material is scraped away by the No. 1 scraper 10,The horizontal scraping mechanism will scrape the surface mineral materials to one side, and finally the surface mineral materials will be scraped into the corresponding collecting hopper 11. When the surface mineral materials fall into the collecting hopper 11, the corresponding spiral feeding mechanism 12 will re-inject the surface mineral materials in the collecting hopper 11 into the corresponding feeding bin 8. When the surface mineral materials are returned, the No. 1 lifting platform 4 will drive several pressing blocks 5 to press the surface mineral materials in several mold cavities 3 downward to form, and finally obtain a layered permeable brick. When the permeable brick is formed, the No. 2 lifting platform will drive several supporting blocks 6 to rise, so that each permeable brick is lifted out of the corresponding mold cavity 3, and then the formed permeable brick can be taken away by an external mechanical transfer arm (not shown in the figure).
