Description

Technical Field

[0001] The present invention relates to the technical field of block manufacturing, and in particular to a manufacturing device for recycled concrete blocks. Background Art

[0002] In the construction industry, concrete blocks are widely used as important building materials. Among them, recycled concrete blocks are mainly made from waste concrete blocks, broken bricks and stones and other construction waste through a series of processes such as crushing, screening, and mixing. The recycling of these waste materials effectively reduces the environmental pollution caused by construction waste, and at the same time reduces the demand for natural aggregates, greatly saving natural resources.

[0003] A manufacturing device for recycled concrete blocks disclosed in the patent publication number "CN112536888B" drives a pressing box to move onto a baffle through a translation mechanism, so as to transfer the raw materials located above the mold box onto the baffle. At this time, the size specification of the raw materials in the mold box is the same as the volume of the mold core. Although the size of the blocks is ensured to be uniform, in actual use, when the raw materials enter the mold box, the raw materials may not be able to spread smoothly and be evenly distributed due to insufficient fluidity, resulting in a situation where the raw materials in the mold box are locally too thick or too thin. As a result, the too-thin area cannot reach the specified density during the compaction process, thereby reducing the strength and durability of the block at this part.

[0016] The present invention has the following beneficial effects: Through the mixing assembly, after the recycled concrete raw materials are put into the mixing barrel, while the rotating roller and the mixing blades are driven to rotate by the first transmission wheel, the second bevel gear can drive the third bevel gear to rotate in the opposite direction under the action of the first bevel gear, so that the bricklaying raw materials in the mixing barrel are more fully mixed, thus ensuring that the strength and performance of each part of the building block are consistent, and reducing quality defects such as cracks and insufficient strength caused by uneven composition.

[0017] Through the uniform distribution assembly, when the second transmission wheel drives the half gear to rotate, the gear can be intermittently rotated. The gear drives the guide plate to rotate. When the saw teeth on the half gear leave the gear, the gear and the guide plate will reset under the action of the torsion spring. In this way, the guide plate swings back and forth continuously.

The worm transmits the power to the third transmission wheel, the second transmission wheel, and the first transmission wheel through the worm gear. At the same time, with the rotation of the two reciprocating lead screws, the two sliding plates can drive the rubber hammers to reciprocate respectively, so that the rubber hammers continuously hammer the mold frame, making it easier for the air bubbles originally existing in the concrete to be discharged, and the arrangement of concrete particles will also be more compact, thereby improving the density of the concrete, reducing the pores and defects inside the building block, and enhancing the strength and durability of the recycled concrete building block.

[0019] Through the oil injection component, drive the lead screw to rotate by the second motor, so that the brick transporting plate and the mold frame slide under the pressing plate. When the electric telescopic rod drives the compaction block on the pressing plate to press down the concrete in the mold frame, the piston rod can drive the piston to move downward. Under the action of the one-way valve, the mold release agent in the fuel tank enters the piston cylinder. After compaction, the electric telescopic rod drives the pressing plate and the piston rod upward. Under the action of the one-way valve, the mold release agent in the piston cylinder is sprayed into the mixing barrel through the oil inlet pipe and the nozzle. Subsequently, when the mold frame and the brick transporting plate are reset, open the solenoid valve, and under the swing of the guide plate, the mold release agent widely covers the inner walls of the mold frame and the grid plate, avoiding damage to the surface of the brick blank due to excessive friction during the demolding process.

A grid plate 27 is fixedly connected inside the mold frame 20. The grid plate 27 can make the formed brick blank have a specific structure and shape. Two sliders 34 are fixedly connected below the brick transporting plate 33. The two sliders 34 are respectively slidably connected to the lead screw 11 and the slide bar 12. When the lead screw 11 rotates, the slider 34 drives the brick transporting plate 33 and the mold frame 20 to move along the slide bar 12. A second motor 25 is fixedly installed outside the mounting plate 2. The transmission shaft of the second motor 25 is fixedly connected to the lead screw 11. Starting the second motor 25 can drive the lead screw 11 to rotate. The mixing assembly is used for fully mixing the concrete; The uniform distribution assembly is used for uniformly distributing the concrete inside the mold frame 20; The vibrating assembly is used for vibrating the concrete inside the mold frame 20; The oil spraying assembly is used for facilitating the demolding of the brick blank, The mixing assembly is composed of a mixing barrel 3, a rotating roller 37, several mixing blades 38 and mixing wings 36. The mixing barrel 3 is fixedly installed on the inner wall of the mounting plate 2, which is the place for mixing concrete. The mixing wings 36 are rotatably connected inside the mixing barrel 3. The rotating roller 37 penetrates through the mixing wings 36 and is rotatably connected to the mixing barrel 3. Several mixing blades 38 are respectively fixedly connected to the rotating roller 37. The blades on the mixing blades 38 and the mixing wings 36 are staggered. This structure makes the mixing more sufficient. A first transmission wheel 8 is rotatably connected to one side of the mounting plate 2. The first transmission wheel 8 is fixedly connected to the rotating roller 37. When the first transmission wheel 8 rotates to drive the rotating roller 37 to rotate, the mixing process will be started.

[0024] A frame plate 22 is fixedly connected to the outside of the mixing barrel 3. A first bevel gear 43 is rotatably connected to the frame plate 22.

When the first bevel gear 43 rotates, it can drive the third bevel gear 35 to rotate in the opposite direction through the second bevel gear 42.

[0025] In this embodiment, after the recycled concrete raw materials are put into the mixing barrel 3, the first transmission wheel 8 drives the roller 37 and the stirring blade 38 to rotate, and the second bevel gear 42 can be driven by the first bevel gear 43 to drive the third bevel gear 35 to drive the stirring wing 36 to rotate in the opposite direction, so that the bricklaying materials in the mixing barrel 3 can be more fully stirred, thereby ensuring that the strength and performance of each part of the block are consistent, and reducing quality defects such as cracks and insufficient strength caused by uneven components. Embodiment 2:

[0026] Different from the first embodiment, Figure 1 - Figure 5 as well as Figure 8 and Figure 9 , this embodiment also has the following further contents: A groove 29 is provided on the mounting plate 2, and a worm wheel 30 is rotatably connected in the groove 29. The groove 29 provides a rotation space for the worm wheel 30, and the worm wheel 30 can rotate in the groove 29. A half gear 39 is rotatably connected to one side of the mounting plate 2. The half gear 39 meshes with the gear 40 through its saw teeth, so that intermittent power transmission can be achieved, driving the gear 40 to rotate periodically. A second transmission wheel 7 is fixedly connected to the half gear 39, and a first belt 10 is wound around the outer side of the second transmission wheel 7. The second transmission wheel 7 is transmission-connected to the first transmission wheel 8 through the first belt 10. When the half gear 39 rotates, the second transmission wheel 7 can rotate the first transmission wheel 8 through the first belt 10. A third transmission wheel 6 is rotatably connected to the mounting plate 2, and a second belt 9 is wound around the outer side of the third transmission wheel 6. The third transmission wheel 6 is transmission-connected to the second transmission wheel 7 through the second belt 9. The third transmission wheel 6 is fixedly connected to the worm wheel 30. When the worm wheel 30 rotates, the third transmission wheel 6 can rotate the second transmission wheel 7 through the second belt 9. A first motor 5 is fixedly installed on the outer side of the mounting plate 2.

[0027] The uniform distribution component consists of a feeding frame 21, two mounting blocks 24, a guide plate 23 and a gear 40. The feeding frame 21 is arranged below the mixing barrel 3 and is a channel for concrete to flow from the mixing barrel 3 to the mold frame 20. A solenoid valve is provided at the connection between the feeding frame 21 and the mixing barrel 3. The solenoid valve can control the timing and flow rate of concrete feeding. The two mounting blocks 24 are respectively fixedly connected to both sides of the feeding frame 21 to provide rotation support for the guide plate 23. The guide plate 23 is rotatably connected between the two mounting blocks 24. A torsion spring is provided at the connection between the guide plate 23 and the mounting block 24. The torsion spring can reset the guide plate 23 after losing the external force. The gear 40 is rotatably connected to the outer wall of the mounting plate 2 and is fixedly connected to the guide plate 23. When the gear 40 rotates, it will drive the guide plate 23 to rotate, and cooperate with the torsion spring to realize the reciprocating swing of the guide plate 23, so that the concrete is evenly distributed. The vibrating assembly consists of two reciprocating lead screws 47, a worm 31, two slide plates 13 and several rubber hammers 28. The two reciprocating lead screws 47 are respectively rotatably connected in the groove 29. The transmission shaft of the first motor 5 is fixedly connected to the reciprocating lead screw 47. The first motor 5 provides power for the rotation of the reciprocating lead screw 47. The worm 31 is fixedly connected between the two reciprocating lead screws 47 and can rotate synchronously with the two reciprocating lead screws 47. The two slide plates 13 are respectively threadedly connected to the two reciprocating lead screws 47. When the reciprocating lead screw 47 rotates, the slide plate 13 will perform a reciprocating linear motion along the reciprocating lead screw 47. Several rubber hammers 28 are respectively fixedly connected to the two slide plates 13. The reciprocating motion of the slide plate 13 drives the rubber hammers 28 to continuously hammer the mold frame 20, realizing the vibrating function. The two slide plates 13 are respectively slidably connected in the groove 29. The groove 29 plays a guiding and limiting role in the movement of the slide plate 13. At the same time, the worm 31 is meshed with the worm gear 30 to transmit the power from the reciprocating lead screw 47 to the worm gear 30 to drive other related components to operate.

[0028] In this embodiment, when the first motor 5 is started, the reciprocating lead screw 32 drives the worm 31 to rotate. The worm 31 transmits the power to the third transmission wheel 6, the second transmission wheel 7, and the first transmission wheel 8 through the worm gear 30 in sequence, so as to make the stirring assembly work. At the same time, when the second transmission wheel 7 drives the half gear 39 to rotate, the gear 40 can be intermittently rotated. The gear 40 drives the guide plate 23 to rotate. When the saw teeth on the half gear 39 leave the gear 40, the gear 40 and the guide plate 23 will reset under the action of the torsion spring. In this way, the guide plate 23 continuously reciprocates. Therefore, when the solenoid valve is opened, affected by the swing, the stirred concrete changes the falling direction and path and evenly falls into the mold frame 20, widely covering the internal space of the mold frame 20, avoiding concentrated accumulation, reducing the vacant space inside the grid plate 27, and realizing the uniform distribution of the concrete in the mold frame 20. At the same time, under the rotation of the two reciprocating lead screws 32, the two slide plates 13 can respectively drive the rubber hammers 28 to perform reciprocating motions, so that the rubber hammers 28 continuously hammer the mold frame 20, making the air bubbles originally existing inside the concrete easier to discharge, and the arrangement between the concrete particles will be closer, thereby improving the density of the concrete, reducing the pores and defects inside the building block, and enhancing the strength and durability of the recycled concrete building block. Embodiment Three:

[0029] Refer to Figure 1 、 Figure 8 、 Figure 9 and Figure 11 Compared with Embodiment One and Embodiment Two, in this embodiment: There are two electric telescopic rods 15 fixedly installed below the support plate 41. The output ends of the two electric telescopic rods 15 are fixedly connected with a pressing plate 14. A plurality of compaction blocks 19 are fixedly connected below the pressing plate 14. The plurality of compaction blocks 19 are attached to the concave parts of the grid plate 27. When the electric telescopic rod 15 drives the pressing plate 14 to descend, the compaction blocks 19 can compact the concrete in the mold frame 20, making the brick blank formed tightly. A piston cylinder 17 is fixedly connected to the support plate 41.

[0030] The oil injection assembly consists of a piston rod 45, a piston 46, an oil outlet pipe 16 and a nozzle 44. The piston rod 45 is slidably connected to the piston cylinder 17. The piston 46 is slidably connected inside the piston cylinder 17. The piston 46 is fixedly connected to one end of the piston rod 45. The piston 46 can be driven to slide inside the piston cylinder 17 by the piston rod 45. The oil outlet pipe 16 is connected to the piston cylinder 17. The nozzle 44 is connected to the end of the oil outlet pipe 16 far from the piston cylinder 17.

[0031] A fuel tank 4 is fixedly installed on the support plate 41. An oily mold release agent is contained in the fuel tank 4, which can effectively reduce the friction between the brick blank and the mold frame, facilitating the smooth demolding of the brick blank. The piston rod 45 is fixedly connected to the pressing plate 14. An oil inlet pipe 18 is connected to the piston cylinder 17. Check valves are provided at the connection points of the piston cylinder 17 with the oil inlet pipe 18 and the oil outlet pipe 16. The end of the oil inlet pipe 18 far from the piston cylinder 17 is connected to the fuel tank 4. When the electric telescopic rod 15 drives the pressing plate 14 downward, the piston rod 45 can drive the piston 46 to move downward inside the piston cylinder 17, generating negative pressure inside the piston cylinder 17. Under the action of the check valve, the mold release agent in the fuel tank 4 will be sucked into the piston cylinder 17 through the oil inlet pipe 18; when the pressing plate 14 drives the piston rod 45 upward, the piston rod 45 drives the piston 46 to move upward, the space inside the piston cylinder 17 decreases, and the pressure increases. At this time, the mold release agent will be sprayed into the mixing barrel 3 through the oil outlet pipe 16 and the nozzle 44 under the action of the pressure.

[0032] In this embodiment, the second motor 25 drives the lead screw 11 to rotate, so that the brick transporting plate 33 and the mold frame 20 slide below the pressing plate 14. When the electric telescopic rod 15 drives the compaction blocks 19 on the pressing plate 14 to press the concrete in the mold frame 20 downward, the piston rod 45 can drive the piston 46 to move downward. Under the action of the check valve, the mold release agent in the fuel tank 4 enters the piston cylinder 17. After compaction, the electric telescopic rod 15 drives the pressing plate 14 and the piston rod 45 upward. Under the action of the check valve, the mold release agent in the piston cylinder 17 is sprayed into the mixing barrel 3 through the oil inlet pipe and the nozzle 44. Subsequently, when the mold frame 20 and the brick transporting plate 33 are reset, the solenoid valve is opened, and under the swinging of the guide plate 23, the mold release agent widely covers the inner walls of the mold frame 20 and the grid plate 27, avoiding damage to the surface of the brick blank due to excessive friction during the demolding process.
