Description

Technical Field

[0001] The invention relates to the technical field related to concrete processing and molding, and in particular to a concrete molding device for processing iron tailings sand. Background Art

[0002] A large amount of tailings will be generated during the mining and beneficiation of ore. Iron ore, which is the most widely used and consumed in my country, produces a huge amount of iron tailings every year. As a waste resource, the utilization rate of iron tailings sand in my country is still relatively low, especially in the efficient and high value-added utilization of iron tailings resources. Applying iron tailings powder as an admixture to concrete can not only achieve the purpose of absorbing a large amount of iron tailings, but also reduce the amount of cement in concrete, which is conducive to energy conservation and emission reduction and carbon emissions, and can also alleviate the current shortage of high-quality admixtures such as fly ash and slag in many areas. Concrete components are a common building structural component, made of concrete and mostly used in the structure and decoration of buildings. Common ones include beam components, wall components and frame components, etc., which are used to support buildings to ensure stability. During production, molds or templates are often used to form cavities to accommodate raw materials for molding, and demolding is performed after molding. When performing concrete molding operations, the staff first needs to place the iron tailings and concrete raw materials in the concrete mixing and extruding device. After the mixing and stirring is completed, the staff first needs to brush the release agent into the concrete molding molds one by one, and then the concrete molding molds that have been brushed with the release agent need to be placed one by one at the bottom of the concrete mud outlet of the equipment to receive the concrete mud. The operation is cumbersome, time-consuming and labor-intensive. Simultaneously, after the concrete molding mold receives the concrete mud, the staff needs to repeatedly knock or stir the mold to reduce the bubbles therein, which is time-consuming, labor-intensive and labor-intensive.

[0024] The following is a further description of the method and principle of using the technical solution in this specific implementation method in conjunction with the accompanying drawings: When performing the concrete forming operation, the staff will first place the box body 35 on the plate chain conveyor belt 11, and make the two clamping limit plates 13 and the clamping grooves 38 complete the clamping; then the staff will start the motor 21, and the power output shaft of the motor 21 rotates to drive the second transmission shaft 20 connected to it to rotate, and the second transmission shaft 20 rotates to drive the first bevel gear 22 concentric with it to rotate, and the first bevel gear 22 rotates to drive the second bevel gear 23 meshing with it to rotate, and the second bevel gear 23 rotates to drive the third transmission shaft 24 and the first pulley 25 concentric with it to rotate, and the first pulley 25 rotates to drive the second pulley 46 to rotate through the transmission belt, and the second pulley 46 rotates to drive the fifth transmission shaft 45 and the incomplete gear 47 concentric with it to rotate, and the incomplete gear 47 rotates to drive the second gear 48 meshing with it to rotate, and the second gear 48 rotates to drive a third transmission shaft 24 and a first pulley 25 concentric with it to rotate. A transmission shaft 9 rotates, and then the intermittent movement of the placement box 35 can be completed through the plate chain conveyor belt 11; the synchronous rotation of the second transmission shaft 20 drives the second transmission roller 26 to rotate, and the rotation of the second transmission roller 26 causes the shaft protrusion 31 on the driving ring 30 in the sliding cavity 27 to slide back and forth along the horizontal slide groove 28 and the V-shaped slide groove 29, thereby causing the driving ring 30 to reciprocate up and down in the sliding cavity 27, and then the driving ring 30 drives the release agent brush plate 33 to reciprocate up and down through the driving rod 32; wherein when the shaft protrusion 31 is located in the horizontal slide groove 28, the incomplete gear 47 is meshed with the second gear 48 for transmission, and when the shaft protrusion 31 is located in the V-shaped slide groove 298, the incomplete gear 47 is idle and does not mesh with the second gear 48; and then when the placement box 35 is stationary, the release agent brush plate 33 reciprocates up and down to apply the release agent to the concrete forming groove 40; When the release agent brush plate 33 moves upward, the four diagonal support guide plates 34 on the driving rod 32 can open the sealing ring 19. At this time, the release agent can flow along the driving rod 32 from the gaps opened by the four diagonal support guide plates 34 to the release agent brush plate 33 to replenish the release agent. Synchronously, when the placement box 35 moves to the bottom of the concrete slurry stirring and extruding device 4, the concrete slurry stirring and extruding device 4 can pour concrete slurry into the concrete forming groove 40. Then, during the movement of the placement box 35, the first gear 44 meshes with the rack plate 8, and the first gear 44 rotates to drive the fourth transmission shaft 42 to rotate, and the fourth transmission shaft 42 rotates to drive the cam 43 to rotate, so that the concrete forming box 39 above it can be knocked and lifted. Synchronously, during the falling process of the concrete forming box 39, the bottom wall of the concrete forming box 39 first contacts the shock column 37, and at this time, the bottom wall of the concrete forming box 39 is out of contact with the cam 43, and then the falling of the concrete forming box 39 and the counter-vibration of the shock column 37 can further accelerate the discharge of concrete bubbles in the concrete forming groove 40. Synchronously, when the placement box 35 moves to be close to the receiving platform 5, first during the movement of the placement box 35, the first gear 44 transitions from the rack plate 8 to the guide plate 7 for horizontal sliding, and then when the placement box 35 moves to the end of the horizontal section of the plate chain conveyor belt 11, the engaging limit plate 13 moves downward along with the plate chain, thereby disengaging the placement box 35 from the plate chain conveyor belt 11, and the bottom wall of the placement box 35 contacts the guide plate 6. At this time, the staff can move the placement box 35 to the receiving platform 5 and place it in a selected place.
