Detailed implementation manners

[0031] 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.

[0032] Please refer to Figures 1 - 11, the present invention provides a technical solution: a cement precast pouring and forming device, comprising: a horizontal conveyor 1, the horizontal conveyor 1 is a belt conveyor, and a vibration motor is installed corresponding to the lower part of the storage hopper 3 in the middle of the horizontal conveyor 1 for vibrating the forming die 28 below the storage hopper 3. A plurality of extrusion blocks 24 with inclined surface structures are fixedly connected at equal intervals on the conveyor belt of the horizontal conveyor 1. The middle of the top of the extrusion block 24 is a flat structure, and both ends are inclined surface structures; the storage hopper 3 is fixedly connected to the top of the horizontal conveyor 1, and a blanking hole 6 is provided at the bottom of the storage hopper 3. A blanking part is arranged in the middle of the blanking hole 6 for controlling the blanking speed and preventing blockage; the extrusion blocks 24 are fixedly connected at equal intervals on the conveyor belt of the horizontal conveyor 1, and a limiting frame 27 is fixedly connected to the top of the horizontal conveyor 1. The forming die 28 is stacked inside the limiting frame 27. The forming die 28 is a cavity with an opening at the top. The front view of the forming die 28 is a T-shaped structure. A lower baffle 30 and an upper baffle 31 for limiting the two layers of forming dies 28 at the bottom are arranged on one side of the limiting frame 27; the blanking component includes a bracket 8 fixedly connected above the horizontal conveyor 1. A steel bar frame 35 is stacked on the top of the bracket 8. A rotating shaft 13 is rotatably connected to the middle of the bracket 8. Upper limiting plate 14 and lower limiting plate 15 perpendicular to each other are fixedly connected to the outside of the rotating shaft 13. The top of the bracket 8 includes a driving part for driving the rotating shaft 13 to rotate. The driving part includes an extrusion inclined block 16 that is extrusion-fitted with the extrusion block 24. Two racks 10 for driving the rotating shaft 13 to rotate are arranged on the inclined surface side of the extrusion inclined block 16. The top of the two racks 10 are respectively connected with a sliding bottom plate 25 for controlling the opening and closing of the blanking hole 6 and an extrusion plate 34 for driving the position switching of the lower baffle 30 and the upper baffle 31; when the extrusion block 24 cooperates with the extrusion inclined block 16, the forming die 28 and the steel bar frame 35 at the second layer from the bottom are limited, the forming die 28 and the steel bar frame 35 at the bottom layer fall, and the sliding of the sliding bottom plate 25 opens the bottom of the blanking hole 6.

[0033] It should be noted that, when the equipment is initially started, the two forming dies 28 are placed below the storage hopper 3 and the bracket 8, respectively. In the process of the horizontal conveyor 1 conveying forward, the extrusion block 24 cooperates with the extrusion bevel 16, and the extrusion bevel 16 moves upward to extrusion drive the rack 10, and the rack 10 drives the extrusion plate 34 to drive the upper baffle 31 to slide. Under the action of the lever principle, the upper baffle 31 is inserted into the limit frame 27 to block the forming die 28 of the second layer at the bottom, and the lower baffle 30 is separated from the forming die 28 of the lowest layer at the bottom, so that the forming die 28 falls onto the horizontal conveyor 1. At the same time, the rack 10 drives the rotating shaft 13 rotates, so that the upper limit plate 14 is rotated and inserted between the two lowest steel frames 35, the lower limit plate 15 is separated from the lowest steel frame 35, and the lowest steel frame 35 falls into the forming mold 28 below. The rack 10 drives the sliding bottom plate 25 to move when driving, so that the bottom of the discharge hole 6 is in an open state, and the cement concrete falls into the forming mold 28 through the discharge hole 6. When the extrusion block 24 is separated from the extrusion oblique block 16, the rack 10 is reset under the action of elastic force, the upper limit plate 14 and the upper baffle 31 are reset, and the forming mold 28 and the steel frame 35 both fall downward, and the lower baffle 30 and the lower limit plate 15 respectively limit and block them.

[0034] like Figure 1 、 2 As shown in Figures 4, 6 and 8, a feeding conveyor 2 is provided above the horizontal conveyor 1. The feeding conveyor 2 is tilted. The storage hopper 3 is located below the discharge port of the feeding conveyor 2. A feeding port is provided on the top of the storage hopper 3. A discharge part is provided in the middle of the storage hopper 3. The discharge part includes two stirring rods 5 rotatably connected to the inside of the storage hopper 3. The two stirring rods 5 are connected by a spur gear set. A shaftless hollow screw 7 is fixed to the bottom of the stirring rod 5 for controlling the discharge speed and preventing blocking. The shaftless hollow screw 7 is rotatably installed inside the discharge hole 6. A motor 4 is installed on the top of the storage funnel 3, and the output end of the motor 4 is fixedly connected to one of the stirring rods 5. The sliding bottom plate 25 is slidably connected to the bottom of the storage funnel 3. The bottom of the sliding bottom plate 25 is provided with a discharge hole 26 that cooperates with the discharge hole 6. When the discharge hole 26 is misaligned with the discharge hole 6, the discharge hole 6 is blocked. The sliding bottom plate 25 is fixed to the rack 10 through a metal rod. The top of the metal rod is fixedly connected to a magnetic switch 36. The magnetic switch 36 is electrically connected to the motor 4. The outer side of the storage funnel 3 is fixed with a magnetic strip 37 that cooperates with the magnetic switch 36.

[0035] It should be noted that, in the present invention, the mixed concrete is transported into the paper storage funnel 3 through the feeding conveyor 2. When the extrusion block 24 cooperates with the extrusion bevel block 16, the rack 10 moves toward one end, and the rack 10 drives the sliding bottom plate 25 to slide at the bottom of the storage funnel 3 through the metal rod. When the extrusion bevel 16 contacts the plane at the top of the extrusion block 24, the discharge hole 26 is concentric with the feed hole 6, and the material can be transported downward through the feed hole 6 and the discharge hole 26. During the sliding process, the magnetic switch 36 corresponds to the magnetic strip 37, and the magnetic switch 36 controls the motor 4 to be energized. The motor 4 drives the stirring rod 5 to rotate through two meshing spur gears, and the stirring rod 5 drives the shaftless hollow screw 7 to rotate inside the feed hole 6. The shaftless hollow screw 7 transports the concrete downward. When the extrusion bevel 16 is staggered with the extrusion block 24, under the action of elastic force, the sliding bottom plate 25 resets to one end. At this time, the discharge hole 26 is misaligned with the feed hole 6, the sliding bottom plate 25 blocks the feed hole 6, and the motor 4 stops rotating.

[0036] like Figure 5 、 7 As shown in 8, the bracket 8 includes a support plate 20 fixedly connected to the outside of the horizontal conveyor 1, and a limiting hole 23 is provided in the middle of the support plate 20. The limiting hole 23 is slidably connected to the extrusion oblique block 16, and a roller 17 corresponding to the extrusion block 24 is installed at the bottom of the limiting hole 23. A sliding rod 19 slidably connected to the support plate 20 is fixed to one side of the extrusion oblique block 16. A spring 18 is sleeved on the outside of the sliding rod 19 and located below the support plate 20. The top of the support plate 20 is slidably connected to a push rod 21 through a metal plate, one end of the push rod 21 is fixed to a U-shaped rod 9, and the U-shaped rod 9 is fixed to the rack 10. The other end of the push rod 21 is slidably connected to the inclined surface of the extrusion oblique block 16. A limiting ring is installed at one end of the push rod 21 close to the extrusion oblique block 16, and a spring 22 is installed between the limiting ring and the metal plate.

[0037] It should be noted that during the forward conveying process of the horizontal conveyor 1 of the present invention, the position of the extrusion block 24 corresponds to that of the roller 17. One end of the extrusion block 24 is in contact with the roller 17 through an inclined surface. Under the extrusion effect, the extrusion block 24 drives the roller 17 to move upward slowly. The roller 17 drives the extrusion inclined block 16 to move upward. The extrusion inclined block 16 moves upward along the limiting hole 23, and the extrusion inclined block 16 drives the sliding rod 19 to compress the first spring 18 upward. Moreover, one side of the extrusion inclined block 16 away from the sliding rod 19 is of an inclined surface structure. When the extrusion inclined block 16 moves upward, the extrusion inclined block 16 extrudes the ejector rod 21, causing the ejector rod 21 to move towards one end. During the movement of the ejector rod 21, the second spring 22 is compressed. When the ejector rod 21 moves towards one end, it pushes the rack 10 through the U-shaped rod 9. Thus, the extrusion plate 34 and the sliding bottom plate 25 are driven to move through the rack 10. When the extrusion block 24 and the roller 17 are misaligned, the first spring 18 drives the extrusion inclined block 16 to reset through the sliding rod 19, and the second spring 22 drives the ejector rod 21 to reset. The ejector rod 21 drives the rack 10 to reset through the U-shaped rod 9.

[0038] As Figure 7 、 8 Shown in FIGS. 10, 11, the rack 10 is slidably connected to the bracket 8. A gear 12 is meshed and connected to the outside of the rack 10. The gear 12 is fixedly connected to the outside of the rotating shaft 13. The heights of the lower limiting plate 15 and the upper limiting plate 14 are adapted to the height of the steel bar frame 35.

[0039] It should be noted that when the rack 10 of the present invention moves towards one side, the rack 10 drives the rotating shaft 13 to rotate counterclockwise in the middle of the bracket 8 through the gear 12. The rotating shaft 13 drives the lower limiting plate 15 and the upper limiting plate 14 to rotate. The upper limiting plate 14 rotates into the space between the two bottom steel bar frames 35, and the lower limiting plate 15 is separated from the bottommost steel bar frame 35. Thus, the second-layer steel bar frame 35 at the bottom is limited and blocked. After the bottommost steel bar frame 35 loses the limitation of the lower limiting plate 15, it automatically drops. When the rack 10 resets, the lower limiting plate 15 is located below the steel bar frame 35, and the upper limiting plate 14 rotates out from the middle of the steel bar frame 35. Under the action of gravity, the steel bar frame 35 falls onto the top of the lower limiting plate 15. By cycling in this way, successive discharging is achieved, and the automatic placement of the steel bar frame 35 is realized.

[0040] As Figure 3 、 4As shown in FIGS. 10, 11, one side of the limit frame 27 is rotatably connected with a driving rod 29. Both the lower baffle 30 and the upper baffle 31 are provided with rectangular holes that cooperate with the driving rod 29. The driving rod 29 is slidably connected with the rectangular holes. The limit frame 27 is provided with sliding holes for the upper baffle 31 and the lower baffle 30 to slide. One side of the limit frame 27 is fixedly connected with a guide rod 33 that is slidably connected with the upper baffle 31. A third spring 32 is sleeved outside the guide rod 33. One side of the pressing plate 34 is provided with a bevel structure, and the height of the bevel structure corresponds to that of the upper baffle 31. When the lower baffle 30 limits the bottommost forming die 28, the upper baffle 31 is located in the sliding hole of the limit frame 27. When the upper baffle 31 limits the forming die 28 at the second layer from the bottom, the lower baffle 30 is located in the sliding hole.

[0041] It should be noted that the length of the upper baffle 31 of the present invention is greater than that of the lower baffle 30. In the natural state, one end of the upper baffle 31 is flush with the inner wall of the limit frame 27. When the rack 10 moves forward, the rack 10 drives the pressing plate 34 to contact the upper baffle 31. Due to the bevel structure on one side of the pressing plate 34, the pressing plate 34 slowly presses the upper baffle 31 into the limit frame 27. The upper baffle 31 first blocks the forming die 28 at the second layer from the bottom. While compressing the third spring 32, the upper baffle 31 drives the driving rod 29 to rotate. The bottom of the driving rod 29 pulls the lower baffle 30 out of the limit frame 27, so that the lower baffle 30 is separated from the bottommost forming die 28. Under the action of gravity, the forming die 28 falls onto the lower horizontal conveyor 1. When the rack 10 drives the pressing plate 34 to reset, the third spring 32 drives the upper baffle 31 to reset. The upper baffle 31 drives the lower baffle 30 to insert into the limit frame 27 through the driving rod 29. When the upper baffle 31 enters the sliding hole, the forming die 28 falls onto the top of the lower baffle 30 under the action of gravity, and the lower baffle 30 limits it. By circulating in this way, the automatic feeding of the forming die 28 is realized.
