Description

Technical Field

[0001] This utility model relates to a feeding device, specifically a feeding device for concrete blocks. Background Technology

[0002] Hexagonal concrete blocks are generally produced through concrete pouring. The production process includes applying oil to the mold, pouring, molding, demolding, and curing. The pouring and molding processes involve unloading the prepared concrete into a hexagonal mold, where the mold shapes the concrete into blocks. Patent application CN220244550U discloses a feeding device for aerated concrete blocks, which includes a screw feeder. The screw feeder includes a screw conveyor cylinder and a drive motor that rotates the screw conveyor cylinder. A receiving box is installed at the bottom of the screw conveyor cylinder, and the discharge port of the screw conveyor is connected to a discharge cylinder via a connecting sleeve. A sliding block is installed at the bottom of the discharge cylinder, and an adjusting mechanism is installed at the bottom of the sliding block. This invention has high raw material conveying efficiency. By setting up the adjusting mechanism, the discharge position can be easily adjusted during conveying, making feeding more convenient and the discharge more uniform during aerated concrete production, effectively reducing labor intensity.

[0003] The aforementioned feeding equipment can feed concrete, but it is not easy to feed it quantitatively. If too much concrete is fed, it easily overflows from the mold, causing waste and increasing production costs; if too little concrete is fed, the formed concrete blocks may lack strength, resulting in substandard products. Therefore, it is necessary to design a concrete block feeding device to solve these problems. Summary of the Invention

[0024] The concrete block feeding device consists of a mixing mechanism, a quantitative feeding mechanism, and a conveyor belt 1 arranged sequentially from top to bottom. The mixing mechanism mixes sand, stone, and cement evenly to form concrete; the quantitative feeding mechanism feeds a fixed amount of concrete into the mold; the conveyor belt 1 conveys a pallet 21, which in turn conveys the mold 22 fixed on the pallet 21, and then conveys the mold to the area below the quantitative feeding mechanism so that the concrete can be fed into the mold.

[0025] The quantitative feeding mechanism consists of a weighing support 2, a weighing sensor 3, a weighing hopper 4, a discharge auger 5, and a discharge hopper 6. The weighing sensor 3 is located at the bottom of the weighing support 2, and the weighing hopper 4 is located at the top of the weighing support 2 to store a certain amount of concrete, which is then fed into the mold. The discharge auger 5 is arranged parallel to the bottom outlet of the weighing hopper 4 to convey viscous concrete from the weighing hopper 4, thus discharging the concrete. The conveying volume of the discharge auger 5 is the concrete discharge volume. The discharge hopper 6 is located at the end of the discharge auger 5 to guide the concrete, ensuring that the concrete is discharged into the mold. The function of the weighing sensor 3 is to detect the weight of the entire quantitative feeding mechanism, and then calculate the amount of concrete to be fed into the weighing hopper 4 by the weight change of the quantitative feeding mechanism, thereby controlling the amount of concrete to be fed into the mold so that the amount of concrete to be fed into the mold will not overflow and be wasted, and the strength of the concrete blocks after molding will be guaranteed.

[0026] A switch bracket 7 is mounted on the discharge auger 5 above the discharge hopper 6 via a pin. A baffle 8 is fixedly mounted at the bottom of the switch bracket 7, and the baffle 8 is sealed to the port of the discharge auger 5. A switch cylinder 9 is installed on the discharge auger 5 between the switch bracket 7 and the weighing hopper 4. The piston rod end of the switch cylinder 9 is movably connected to the switch bracket 7 via a pin. The function of the switch cylinder 9 is to drive the switch bracket 7 to swing around the pin between the switch bracket 7 and the discharge auger 5, thereby driving the baffle 8 to move around the pin between the switch bracket 7 and the discharge auger 5. This allows the baffle 8 to close or open the port of the discharge auger 5, thus ensuring that concrete in the discharge auger 5 does not easily flow out of the discharge auger 5 when not in a discharge state. This avoids concrete waste and contamination of the support plate or conveyor belt 1 supporting the mold.

[0027] A vibration mechanism is installed between the conveyor belts 1 below the discharge auger 5. The vibration generated by the vibration mechanism drives the mold to vibrate, thereby vibrating, leveling, and venting the concrete in the mold, ensuring that the concrete blocks are uniform, flat, and have good strength, thus improving the quality of the formed concrete blocks.

[0028] The vibration mechanism consists of a vibrating plate 10, a polarizing motor 11, a polarizing rotor 12, and anti-friction rollers 13. The polarizing motor 11 is fixedly mounted on the bottom of the vibrating plate 10 via a clamp, and the polarizing rotor 12 is mounted on the output shaft of the polarizing motor 11. Anti-friction rollers 13 are evenly distributed on the top of the vibrating plate 10 and are slidably connected to the conveyor belt 1. The vibrating plate 10 is fixedly connected to the support of the conveyor belt 1. The function of the polarizing motor 11 is to drive the polarizing rotor 12 to rotate. Due to the eccentricity of the polarizing rotor 12, vibration is generated by the rotating rotor 12, which in turn drives the vibrating plate 10 and the anti-friction rollers 13 to vibrate, thereby driving the conveyor belt 1, which is slidably connected to the anti-friction rollers 13, to vibrate. This, in turn, causes the pallet and mold on the conveyor belt 1 to vibrate, applying the vibration to the concrete in the mold. The function of the anti-friction rollers 13 is to reduce the friction between the vibration mechanism and the conveyor belt 1, extending the service life of the conveyor belt 1.

[0029] Guide plates 14 are respectively installed on the weighing supports 2 on both sides of the conveyor belt 1 to guide the pallet and then guide the mold. On the one hand, this prevents the pallet from shifting and thus prevents the pallet from separating from the conveyor belt 1; on the other hand, it ensures that the mold can move to the bottom of the hopper 6, thus ensuring that the concrete can be accurately discharged into the mold.

[0030] The mixing mechanism consists of a mixing support 15, a mixer 16, a feed hopper 17, and a discharge hopper 18. The mixer 16 (horizontal mixer) is mounted on the mixing support 15. The feed hopper 17 is located at the top of the mixer 16, and the discharge hopper 18 is located at the bottom of the mixer 16, with its bottom port extending into the weighing hopper 4. The function of the mixer 16 is to mix the sand, gravel, and cement entering from the feed hopper 17 to form concrete, which is then supplied to the weighing hopper 4. A gate valve 19 is installed between the discharge hopper 18 and the mixer 16 to control the discharge of concrete from the mixer 16 into the weighing hopper 4. A water inlet 20 is connected to the mixer 16 to allow water to enter the mixer 16.

[0031] When the concrete block feeding device is working, it feeds concrete into the mixer 16 through the feed hopper 17 of the mixing mechanism to form concrete. After mixing, the gate valve 19 is opened to release the concrete from the mixer 16 and the discharge hopper 18, storing it in the weighing hopper 4. The conveyor belt 1 drives the pallet and mold placed on the conveyor belt 1 to move below the quantitative feeding mechanism. When the mold moves below the discharge hopper 6 of the quantitative feeding mechanism, the conveyor belt 1 stops. After the conveyor belt 1 stops, the polarization motor 11 of the vibration mechanism is started. The polarization motor 11 drives the mold to vibrate in sequence through the polarization rotor 12, the vibrating plate 10, the anti-friction roller 13, the conveyor belt 1, and the pallet. The switching cylinder 9 opens the baffle 8 at the port of the discharge auger 5 through the switching bracket 7, starting the discharge auger 5. The discharge auger 5 transports the concrete in the weighing hopper 4 outward. The concrete is discharged into the mold in sequence through the discharge auger 5 and the discharge hopper 6. During the feeding process, the weight of the quantitative feeding mechanism is detected by the weighing sensor 3, and the amount of concrete to be fed is calculated by the weight difference, thereby controlling the concrete feeding. During the feeding process, the concrete in the mold is vibrated to homogenize, level, and vent air. After feeding is completed, the discharge auger 5 is stopped, the baffle 8 is closed, and the conveyor belt 1 is started to transport the mold to the bottom of the feeding hopper 6, and the feeding process is repeated.

[0032] This concrete block feeding device weighs the concrete using a weighing mechanism and calculates the feeding quantity based on the weight difference of the discharged concrete. This ensures precise quantitative feeding, meeting the strength requirements after molding while minimizing waste and reducing production costs. Parallel discharge augers allow for simultaneous feeding, effectively improving feeding efficiency and thus production efficiency. Vibration energy homogenizes, levels, and vents the discharged concrete, resulting in flat, uniform, and dense molded concrete blocks, significantly improving their quality. This solves the problem of existing feeding equipment's inability to quantitatively feed concrete.
