[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 inclined block 16, and the extrusion inclined block 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 second layer of the forming die 28 at the bottom, and the lower baffle 30 is separated from the forming die 28 at the bottom layer, 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 bars 35, the lower limit plate 15 is separated from the lowest steel bar frame 35, and the lowest steel bar 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 feed hole 6 is in an open state, and the cement concrete falls into the forming mold 28 through the feed hole 6. When the extrusion block 24 is separated from the extrusion inclined block 16, the rack 10 is reset under the action of elastic force, the upper limit plate 14 and the upper baffle plate 31 are reset, and the forming mold 28 and the steel bar frame 35 both fall downward, and the lower baffle plate 30 and the lower limit plate 15 limit and block them respectively.

[0034] like Figure 1 , 2 As shown in , 4, 6, and 8, a feeding conveyor 2 is arranged above the horizontal conveyor 1, and the feeding conveyor 2 is arranged at an angle. The storage hopper 3 is located below the discharge port of the feeding conveyor 2, and a feeding port is arranged on the top of the storage hopper 3. A discharge part is arranged in the middle of the storage hopper 3, and 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 blockage; the shaftless hollow screw 7 is rotatably installed in 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. A discharge hole 26 cooperating with the discharge hole 6 is provided at the bottom of the sliding bottom plate 25. When the discharge hole 26 is misaligned with the discharge hole 6, the discharge hole 6 is blocked. The sliding bottom plate 25 is fixedly connected to the rack 10 through a metal rod, and a magnetic switch 36 is fixedly connected to the top of the metal rod. The magnetic switch 36 is electrically connected to the motor 4, and a magnetic strip 37 cooperating with the magnetic switch 36 is fixedly connected to the outer side of the storage funnel 3.

[0035] It should be noted that, in the present invention, the mixed concrete is conveyed into the paper storage funnel 3 through the feeding conveyor 2. When the extrusion block 24 cooperates with the extrusion inclined block 16, the rack 10 moves to 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, the sliding bottom plate 25 is reset to one end under the action of elastic force. At this time, the discharge hole 26 is staggered 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, a limiting hole 23 is provided in the middle of the support plate 20, the limiting hole 23 is slidably connected to the extrusion inclined block 16, 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 fixedly connected to one side of the extrusion inclined block 16, a spring 18 is sleeved on the outside of the sliding rod 19 and located below the support plate 20, a push rod 21 is slidably connected to the top of the support plate 20 through a metal plate, one end of the push rod 21 is fixedly connected to a U-shaped rod 9, the U-shaped rod 9 is fixedly connected to the rack 10, the other end of the push rod 21 is slidably connected to the inclined surface of the extrusion inclined block 16, a limiting ring is installed at one end of the push rod 21 close to the extrusion inclined block 16, and a spring 22 is installed between the limiting ring and the metal plate.

[0037] It should be noted that, in the process of the horizontal conveyor 1 conveying forward, the positions of the extrusion block 24 and the roller 17 correspond, and the inclined surface of one end of the extrusion block 24 contacts the roller 17. Under the action of extrusion, the extrusion block 24 drives the roller 17 to move upward slowly, and 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 slide bar 19 to compress the spring 18 upward, and the side of the extrusion inclined block 16 away from the slide bar 19 is a slope structure. When moving upward, the extrusion bevel block 16 squeezes the push rod 21 to make the push rod 21 move toward one end. During the movement of the push rod 21, the spring 22 is compressed. When the push rod 21 moves toward one end, the rack 10 is pushed through the U-shaped rod 9, thereby driving the extrusion plate 34 and the sliding bottom plate 25 to move through the rack 10. When the extrusion block 24 is misaligned with the roller 17, the spring 18 drives the extrusion bevel block 16 to reset through the sliding rod 19, the spring 22 drives the push rod 21 to reset, and the push rod 21 drives the rack 10 to reset through the U-shaped rod 9.

[0038] like Figure 7 , 8 As shown in 10 and 11, the rack 10 is slidably connected to the bracket 8, and the outer side of the rack 10 is meshed with a gear 12, which is fixed to the outer side of the rotating shaft 13. The height of the lower limit plate 15 and the upper limit plate 14 is adapted to the height of the steel frame 35.

[0039] It should be noted that when the rack 10 of the present invention moves to one side, the rack 10 drives the rotating shaft 13 to rotate counterclockwise in the middle of the bracket 8 through the gear 12, and the rotating shaft 13 drives the lower limit plate 15 and the upper limit plate 14 to rotate, and the upper limit plate 14 rotates to enter between the two bottom steel frames 35, and the lower limit plate 15 is separated from the bottom steel frame 35, so that the steel frame 35 of the second layer at the bottom is limited and blocked, and the bottom steel frame 35 automatically falls down after there is no limit of the lower limit plate 15. When the rack 10 is reset, the lower limit plate 15 is located below the steel frame 35, and the upper limit plate 14 rotates out from the middle of the steel frame 35. Under the action of gravity, the steel frame 35 falls on the top of the lower limit plate 15, and this cycle is repeated to realize material unloading one by one and automatic placement of the steel frame 35.

[0040] like Figure 3 , 4As shown in , 10 and 11, a driving rod 29 is rotatably connected to one side of the limit frame 27, and the lower baffle 30 and the upper baffle 31 are both provided with rectangular holes that cooperate with the driving rod 29, and the driving rod 29 is slidably connected to the rectangular hole, and the limit frame 27 is provided with a sliding hole for the upper baffle 31 and the lower baffle 30 to slide, and a guide rod 33 slidably connected to the upper baffle 31 is fixedly connected to one side of the limit frame 27, and a spring 32 is sleeved on the outer side of the guide rod 33, and a bevel structure is provided on one side of the extrusion plate 34, and the height of the bevel structure corresponds to that of the upper baffle 31. When the lower baffle 30 limits the bottommost molding mold 28, the upper baffle 31 is located in the sliding hole of the limit frame 27, and when the upper baffle 31 limits the second layer molding mold 28 located at 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 extrusion plate 34 to contact the upper baffle 31. Because one side of the extrusion plate 34 is a slope structure, the extrusion plate 34 slowly squeezes the upper baffle 31 into the limit frame 27. The upper baffle 31 first blocks the molding die 28 located at the second layer at the bottom. The upper baffle 31 drives the driving rod 29 to rotate while compressing the spring 32. The bottom of the driving rod 29 pushes the lower baffle 30 is pulled outward from the inside of the limit frame 27, so that the lower baffle 30 is separated from the molding die 28 at the bottom. Under the action of gravity, the molding die 28 falls onto the horizontal conveyor 1 below. When the rack 10 drives the extrusion plate 34 to reset, the spring three 32 drives the upper baffle 31 to reset. The upper baffle 31 drives the lower baffle 30 to be inserted into the limit frame 27 through the driving rod 29. When the upper baffle 31 enters the sliding hole, the molding die 28 falls to the top of the lower baffle 30 under the action of gravity, and the lower baffle 30 limits it. In this cycle, the automatic discharge of the molding die 28 is realized.
