Description

Technical Field

[0001] The invention relates to the technical field of concrete block manufacturing, in particular to recycled concrete block manufacturing equipment. Background Art

[0002] With the rapid development of the construction industry, the demand for building materials continues to increase, especially concrete blocks, as a common building material. Because of their good strength, durability and ease of construction, they are widely used in various construction projects.

[0003] During the production of concrete blocks, bubbles are easily generated within the concrete. These bubbles not only reduce the density of the concrete but also reduce the strength and durability of the blocks. While traditional mixing equipment can remove some bubbles by stirring the concrete to a certain extent, it is difficult to completely remove the bubbles within the concrete. This is especially true for the tiny bubbles generated during the mixing process, which are even more difficult to remove with simple stirring. Therefore, a recycled concrete block manufacturing equipment is proposed to address this problem. Summary of the Invention

[0052] 1.

The multi-stage push rod in the forming mechanism pushes the upper push plate to apply pressure to the concrete, and at the same time cooperates with the vibration of the degassing mechanism to fully compact the concrete in the forming box, ensuring the dimensional accuracy and shape regularity of the concrete block and improving the appearance quality of the product.

[0053] 2. This recycled concrete block manufacturing equipment features a demolding mechanism that, through the coordination of a fixed frame, reciprocating rod, striking rod, and U-shaped limit rod, allows for smooth demolding of the concrete blocks after forming through vibration and the forward and backward movement of the bottom template. This prevents damage to the blocks caused by demolding difficulties and improves product qualification rates. The demolding process is largely automated, reducing the time and labor required for manual demolding and improving production efficiency.

[0054] 3. When demoulding, the defoaming mechanism of the recycled concrete block manufacturing equipment works in the reverse direction and resets, and uses the swing rod to impact, causing it to swing and generate vibration. The vibration is transmitted through the outer wall of the molding cylinder, promoting the separation of the concrete block from the molding cylinder and the molding box. At the same time, the vibration block and the U-shaped connecting rod move up and down, thereby pushing the concrete block downward, further promoting the separation of the concrete block from the molding box and the molding cylinder, thereby further improving the demoulding effect.

[0072] The debubble mechanism 7 is provided inside the forming box 4 and is used to remove bubbles from the concrete;

[0073] Wherein, the defoaming mechanism 7 comprises:

[0074] A plurality of molding cylinders 71 are movably connected to the top of the bottom template 8 and are used for molding concrete blocks;

[0075] The rack 72 is provided on the molding mechanism 5, and the bottom portion thereof movably passes through the molding cylinder 71 and extends into the interior thereof;

[0076] A plurality of rotating rods 73 are rotatably connected to the inner wall of the molding cylinder 71 at equal intervals, and a gear 74 is fixedly sleeved on the outer wall of each rotating rod 73 and meshes with the rack 72;

[0077] Elliptical discs 75 are fixedly mounted on both sides of the outer wall of each rotating rod 73 and are located on both sides of the gear 74;

[0078] The swing rod 76 is provided on the inner wall of the molding cylinder 71 and fits with the oval disk 75, and the swing rod 76 is connected to the inner wall of the molding cylinder 71 through the spring 2 77;

[0079] The vibration assembly 78 is disposed above the molding cylinder 71 and is used to vibrate the concrete.

[0080] The forming mechanism 5 comprises:

[0081] The upper push plate 51 is connected to the bottom of the top fixed plate 3 through two multi-stage push rods 52, and the two multi-stage push rods 52 are symmetrically arranged on the left and right;

[0082] The mixing drum 53 is fixedly connected to the upper push plate 51 and is used to store concrete;

[0083] The lower barrel 54 is fixedly connected to the top of the mixing barrel 53 and movably passes through the top fixed plate 3. The mixing barrel 53 and the lower barrel 54 are connected to each other and are used to add concrete into the mixing barrel 53.

[0084] A stirring rod 56 is rotatably connected to the top of the inner wall of the mixing barrel 53;

[0085] The motor 55 is installed above the mixing drum 53, and the output end of the motor 55 is connected to the stirring rod 56 for driving the stirring rod 56 to rotate;

[0086] The outer wall of the stirring rod 56 is fixedly connected with a plurality of shifting rods for shifting the concrete.

[0087] Working principle:

[0088] During the concrete block manufacturing process, concrete is first added to the mixing drum 53 via the discharge drum 54. Subsequently, the motor 55 is started, and the output end of the motor 55 rotates the stirring rod 56, which in turn rotates the lever on the stirring rod, thoroughly stirring the concrete in the mixing drum 53 to remove any bubbles. As the concrete is stirred, it flows through the discharge hole between the mixing drum 53 and the upper push plate 51 into the forming box 4. Simultaneously, the stirring rod 56 and the lever continue to operate, ensuring that the concrete falls smoothly into the forming box 4.

[0089] Once the concrete is unloaded, the two multi-stage push rods 52 are activated, pushing the upper push plate 51 downward, applying pressure to the concrete within the molding box 4 and securing it in place. Simultaneously, the upper push plate 51 drives the rack 72 downward, which engages with the gear 74, rotating the gear 74 and, in turn, driving the rotating rod 73. The elliptical disk 75 on the rotating rod 73 rotates accordingly, continuously moving the swing rod 76. Driven by spring 2 77, the swing rod 76 vibrates in an upward and downward deflection. This vibration is transmitted to the concrete through the molding cylinder 71, helping to eliminate bubbles within the concrete and promoting concrete formation.

[0090] See also Figure 1-8 Based on the above embodiment, in another embodiment of the present invention, the vibration component 78 includes:

[0091] The mounting base 781 is fixedly connected to the top of the molding cylinder 71;

[0092] A U-shaped connecting rod 782 is hinged to the mounting base 781 and deflects around the hinge point;

[0093] The vibrating block 783 is hinged to the other side of the U-shaped connecting rod 782 and is used to contact the concrete surface from top to bottom to eliminate bubbles;

[0094] The shift block 784 is fixedly connected to the hinge of the U-shaped connecting rod 782;

[0095] The contact plate 785 is fixedly connected to one side of the shift block 784 , and the contact plate 785 contacts the tooth groove of the rack 72 .

[0096] Two swing rods 76 are respectively provided on both sides of each oval disk 75 , and the swing rods 76 generate up and down deflection vibrations through springs 77 .

[0097] Working Principle: As rack 72 moves downward, it presses down and contacts plate 785, causing it to deflect downward. Once rack 72 is freed from contact, the contact plate 785, thanks to a return spring at the hinge, drives shift block 784 and U-shaped connecting rod 782 upward around the hinge. This process repeats, deflecting U-shaped connecting rod 782 and causing vibrating block 783 to contact the concrete surface, eliminating air bubbles and further improving the concrete's forming quality.

[0098] See also Figure 1-8 On the basis of the above embodiment, in another embodiment of the present invention, the demoulding mechanism 6 includes:

[0099] The fixing frame 61 is provided on the outer wall of the bottom template 8;

[0100] A plurality of fixing columns 62 are fixedly connected to the top of the support 1;

[0101] The outer wall of the fixed frame 61 is movably mounted on the outer wall of the fixed column 62 through a movable block;

[0102] Two reciprocating rods 63 are provided on the front and rear sides of the fixed frame 61, and the reciprocating rods 63 are movably connected to the inner walls of the movable blocks on the front and rear sides;

[0103] a plurality of striking rods 64, one side of which is fixedly connected to the outer wall of the reciprocating rod 63, and the other side of the striking rod 64 is in contact with the fixed frame 61;

[0104] A U-shaped limiting rod 67 is rotatably connected to the outer walls of the two fixed rods 2, and a rotating shaft 68 is provided at the rotating position, and the rotating shaft 68 is rotatably arranged with the fixed rod 2;

[0105] The bottom of the movable block is placed on the outer wall of the U-shaped limiting rod 67.

[0106] The demoulding mechanism 6 also includes:

[0107] The interference groove is formed on the outer wall of the fixing column 62;

[0108] A slide rod 65 is slidably connected to the inner wall of the movable block, and one side of the slide rod 65 abuts against the outer wall of the abutment groove;

[0109] Spring 1 66 is provided on the other side of the slide bar 65 and is used to push the slide bar 65 to move.

[0110] The demoulding mechanism 6 also includes:

[0111] A plurality of fixed slide bars 610 are fixedly connected between the fixed frames 61, and the left and right sides of the fixed frames 61 are opened;

[0112] Two bottom templates 8 are provided and are slidably connected to the outer wall of the fixed slide rod 610;

[0113] The connecting rod 69 has two ends hinged between the bottom template 8 and the reciprocating rod 63, and is used to push the two bottom templates 8 to move.

[0114] A conical bucket is fixedly connected to the upper portion of the outer wall of the forming box 4 , and the conical bucket is fixedly connected to the outer walls of the four fixing rods 2 .

[0115] Working Principle: After the molding process is completed, the U-shaped limit rod 67 is synchronously deflected by rotating the rotating shaft 68, breaking away from the interference with the movable block, which then drives the fixed frame 61 downward. At the same time, the reciprocating rod 63 and the sliding rod 65 move relative to the interference groove on the fixed column 62. Under the action of spring 1 66, the sliding rod 65 is continuously reset, driving the reciprocating rod 63 and the striking rod 64 to hit the outer wall of the fixed frame 61, generating vibration, and promoting the separation of the concrete from the bottom template 8. During the movement of the reciprocating rod 63, the connecting rod 69 pushes the bottom template 8 back and forth on the outer wall of the fixed slide rod 610, causing the bottom template 8 to move relative to the concrete block, thereby smoothly demolding the concrete block;

[0116] Furthermore, the multi-stage push rod 52 is pushed upward, driving the upper push plate 51 upward, which in turn drives the rack 72 upward. As the rack 72 moves upward, the drive gear 74 rotates, driving the rotating rod 73 and the elliptical plate 75 to rotate, striking the swing rod 76, causing it to swing and vibrate. This vibration is transmitted through the outer wall of the molding barrel 71, promoting the separation of the concrete block from the molding barrel 71 and the forming box 4. Simultaneously, the shifting contact plate 785 and the shifting block 784 are deflected, causing the vibrating block 783 and the U-shaped connecting rod 782 to move up and down, thereby pushing the concrete block downward, further promoting the separation of the concrete block from the forming box 4 and the molding barrel 71.

[0117] The present invention provides a recycled concrete block manufacturing apparatus. There are numerous methods and approaches for implementing this technical solution. The foregoing description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Components not specified in this embodiment may be implemented using existing technologies.
