Abstract

This application belongs to the field of expansive concrete technology and discloses a batching device for expansive concrete, including a base plate, a mounting frame, a hopper, a mounting plate, a support plate, a vertical plate, and a sliding plate. A circular opening is provided on one side of the sliding plate, and a receiving tube is provided on the bottom surface of the sliding plate corresponding to the circular opening. A bottom cover that fits with the lower end of the receiving tube is hinged to the receiving tube. A support frame is provided on the mounting plate, and a storage box is provided on the support frame. A discharge pipe is connected to the bottom of the storage box, and the lower end of the discharge pipe slides in contact with the top surface of the sliding plate. The expansive agent in the circular opening is flush with the top surface of the sliding plate.

Description

Technical Field

[0001] This utility model relates to the field of expansive concrete technology, and in particular to a batching device for expansive concrete. Background Technology

[0002] Micro-expansion concrete refers to ordinary concrete with the addition of a certain amount of expansion agent, which allows the concrete to expand during hydration due to the action of the expansion agent, thereby compensating for the shrinkage of the concrete, preventing concrete cracks, and improving the performance of the concrete.

[0003] However, during the batching process, construction workers usually add concrete expansion agents manually to the dry concrete before mixing or to the mixed concrete slurry based on their own experience. This method of addition not only makes it difficult to ensure the accuracy of the dosage and affects the final performance of the concrete, but also significantly increases the labor intensity of the workers. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a batching device for expansive concrete.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a batching device for expansive concrete, comprising a base plate, an mounting frame on the base plate, a hopper on one side of the mounting frame, a mounting plate horizontally mounted on the top of the mounting frame, a support plate horizontally mounted on the top surface of the mounting plate, upright plates on both sides of the support plate on the top surface of the mounting plate, a sliding plate horizontally slidably mounted on the two upright plates, a circular opening on one side of the sliding plate, a receiving tube corresponding to the circular opening on the bottom surface of the sliding plate, a bottom cover hinged to the receiving tube and engaging with the lower end of the receiving tube, a support frame on the mounting plate, a storage box on the support frame, a discharge pipe connected to the bottom of the storage box, and the lower end of the discharge pipe slidingly contacting the top surface of the sliding plate.

[0006] By adopting the above technical solution, an installation frame, a hopper, an installation plate, a support plate, and a receiving pipe are set up. When the receiving pipe is located directly above the support plate, the bottom cover mates with the lower end of the receiving pipe. A sliding plate slides, aligning the circular opening with the discharge pipe. The expanding agent in the storage box flows through the circular opening into the receiving pipe and the circular opening itself. The sliding plate slides downwards towards the hopper, sealing the lower end of the discharge pipe to prevent the expanding agent from falling out. The expanding agent in the circular opening is flush with the top surface of the sliding plate. When the receiving pipe is completely away from the area directly above the support plate, the bottom cover loses its restraint and rotates downwards under gravity, causing the lower end of the receiving pipe to lose its restraint, allowing the expanding agent inside to fall into the hopper and subsequently into the concrete mixer. This ensures that each movement of the sliding plate delivers a fixed amount of expanding agent to the hopper, guaranteeing a consistent dosage of expanding agent added to the concrete mixer each time, ensuring the performance of the expanding concrete, and automatically adding the agent, reducing the labor intensity of workers.

[0007] Furthermore, both of the upright plates are horizontally provided with sliding grooves at their tops, with the openings of the two sliding grooves facing each other. One end of each sliding groove extends directly above the hopper, and the two sides of the sliding plate slide in cooperation with the corresponding sliding grooves.

[0008] By adopting the above technical solution and setting a sliding groove, the stability of the sliding plate is ensured.

[0009] Furthermore, the top surface of the pallet is provided with several mounting grooves arranged at intervals along its length. A rotating column is horizontally rotatably installed in the mounting groove. The axis of the rotating column is perpendicular to the length direction of the pallet. A rubber tube is sleeved on the rotating column, and the upper side of the rubber tube is higher than the top surface of the pallet.

[0010] By adopting the above technical solution, an installation groove, a rotating column, and a rubber tube are set up. When the receiving tube is completely above the support plate, the rubber tube supports the bottom cover to ensure the stability of the fit between the bottom cover and the lower end of the receiving tube. Furthermore, when the sliding plate slides and drives the receiving tube and the bottom cover to move, the rotating column and the rubber tube can rotate to ensure the smooth movement of the receiving tube and the bottom cover.

[0011] Furthermore, a cylinder is horizontally arranged on the top surface of the mounting plate away from the hopper, and a connecting block is provided on the bottom surface of the sliding plate. The piston rod end of the cylinder is connected to the connecting block.

[0012] By adopting the above technical solution, a cylinder and a connecting block are set up. The cylinder drives the connecting block to move, thereby driving the sliding plate and the receiving tube to move.

[0013] Furthermore, two fixed plates are spaced apart on the side of the support plate away from the cylinder, and a rotating column is rotatably arranged between the two fixed plates. The axis of the rotating column is parallel to the axis of the rotating column, and the upper side of the rotating column is flush with the upper side of the rubber tube.

[0014] By adopting the above technical solution, a fixed plate and a rotating column are set up. When the material discharge of the receiving tube is completed and it needs to return to the bottom of the feeding tube to receive material, the sliding plate slides, which drives the receiving tube and the bottom cover to move. The side of the bottom cover contacts the rotating column. The receiving tube continues to move and the bottom cover continues to rotate. When the receiving tube is completely above the support plate, the bottom cover and the lower end of the receiving tube are engaged.

[0015] Furthermore, an installation block is provided on the outer wall of the receiving tube near the cylinder side, and a hinge shaft is horizontally rotatably provided on the installation block. Both ends of the hinge shaft are provided with connecting plates, and the bottom cover is connected to both connecting plates.

[0016] By adopting the above technical solution, and setting up mounting blocks, hinge shafts, and connecting plates, the stability of the bottom cover rotation is ensured.

[0017] Furthermore, the diameter of the circular opening is the same as the inner diameter of the receiving tube, and the inner diameter of the discharge tube is larger than the diameter of the circular opening.

[0018] In summary, this utility model has the following beneficial effects: In this application, an installation frame, a hopper, an installation plate, a support plate, and a receiving tube are provided. When the receiving tube is located directly above the support plate, the bottom cover engages with the lower end of the receiving tube. A sliding plate is slidable, aligning the circular opening with the discharge pipe. The expanding agent in the storage box reaches the receiving tube and the circular opening through this opening. The sliding plate slides downwards towards the hopper, sealing the lower end of the discharge pipe to prevent the expanding agent from falling out. The expanding agent in the circular opening is flush with the top surface of the sliding plate. When the receiving tube is completely away from the area directly above the support plate, the bottom cover loses its restraint and rotates downwards under gravity, causing the lower end of the receiving tube to lose its restraint, allowing the expanding agent inside to fall into the hopper and subsequently into the concrete mixer. This ensures that each movement of the sliding plate delivers a fixed amount of expanding agent to the hopper, guaranteeing a consistent dosage of expanding agent added to the concrete mixer each time, ensuring the performance of the expanding concrete, and automatically adding the agent, reducing the labor intensity of workers.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-6As shown in the embodiment of this application, a batching device for expansive concrete is disclosed, including a base plate 10, a mounting frame 11, a hopper 12, a mounting plate 20, and a receiving pipe 23. The base plate 10 has four mounting ears with mounting holes for connecting it to a concrete mixer. The volume of concrete mixed in the concrete mixer is consistent each time, and the dosage of the expansive agent added is also consistent. The mounting frame 11 is mounted on the base plate 10, and the hopper 12 is mounted on one side of the mounting frame 11, with its lower end corresponding to the feed inlet of the concrete mixer. The mounting plate 20 is horizontally mounted on top of the mounting frame 11. A support plate 30 is horizontally mounted on the top surface of the mounting plate 20. Vertical plates 21 are mounted on both sides of the support plate 30 on the top surface of the mounting plate 20. A sliding plate 22 is horizontally slidably mounted on both vertical plates 21. A circular opening 221 is opened on one side of the sliding plate 22, and a receiving pipe 23 is mounted on the bottom surface of the sliding plate 22 corresponding to the circular opening 221. The receiving pipe 23 and the sliding plate 22 can move synchronously. A bottom cover 24, hinged to the receiving tube 23 and engaging with its lower end, is mounted on the mounting plate 20. A support frame 40 is mounted on the support frame 40, and a storage box 41 is mounted on the support frame 40. A discharge pipe 42 is connected to the bottom of the storage box 41, and the lower end of the discharge pipe 42 slides in contact with the top surface of the sliding plate 22. When the receiving tube 23 is located directly above the support plate 30, the bottom cover 24 engages with the lower end of the receiving tube 23, and the sliding plate 22 slides, aligning the circular opening 221 with the discharge pipe 42. The expanding agent in the storage box 41 passes through the circular opening 221 into the receiving tube 23 and into the circular opening 221. The sliding plate 22 slides downward toward the hopper 12, sealing the lower end of the discharge pipe 42 to prevent the expanding agent in the discharge pipe 42 from falling out. The expanding agent in the circular opening 221 is flush with the top surface of the sliding plate 22. When the receiving tube 23 is completely away from the area directly above the support plate 30, the bottom cover 24 is unrestricted and rotates downwards under gravity, causing the lower end of the receiving tube 23 to be unrestricted, and the expanding agent inside falls into the hopper 12, and then into the concrete mixer. This ensures that the sliding plate 22 delivers a fixed amount of expanding agent to the hopper 12 with each movement, guaranteeing a consistent dosage of expanding agent added to the concrete mixer each time, ensuring the performance of the expanding concrete, and automatically adding the agent, reducing the labor intensity of the workers.

[0028] Specifically, each of the two upright plates 21 has a horizontally arranged groove 25 on its top. The length of the groove 25 is consistent with the length of the support plate 30, and the openings of the two grooves 25 face each other. One end of the groove 25 extends directly above the hopper 12. The two sides of the sliding plate 22 slide in cooperation with the corresponding grooves 25 to ensure the stability of the sliding plate 22. A cylinder 26 is horizontally arranged on the top surface of the mounting plate 20 away from the hopper 12. A connecting block 261 is arranged on the bottom surface of the sliding plate 22. The piston rod end of the cylinder 26 is connected to the connecting block 261. The cylinder 26 drives the connecting block 261 to move, thereby driving the sliding plate 22 and the receiving tube 23 to move. The diameter of the circular opening 221 is the same as the inner diameter of the receiving tube 23, and the inner diameter of the discharge tube 42 is larger than the diameter of the circular opening 221 to ensure the smooth entry of the expanding agent into the circular opening 221 and the receiving tube 23. An installation block 27 is provided on the outer wall of the receiving tube 23 near the cylinder 26. A hinge shaft 28 is horizontally rotatably mounted on the installation block 27. A connecting plate 29 is provided at both ends of the hinge shaft 28. The bottom cover 24 is connected to both connecting plates 29 to ensure the stability of the rotation of the bottom cover 24.

[0029] During installation, several mounting slots 34 are spaced apart along the length of the top surface of the support plate 30. A rotating column is horizontally rotatably mounted within each mounting slot 34, with its axis perpendicular to the length of the support plate 30. A rubber tube 31 is fitted over the rotating column, with its upper side higher than the top surface of the support plate 30. When the receiving tube 23 is completely above the support plate 30, the rubber tube 31 supports the bottom cover 24 to ensure stable engagement between the bottom cover 24 and the lower end of the receiving tube 23. Furthermore, when the sliding plate 22 slides, causing the receiving tube 23 and the bottom cover 24 to move, the rotating column and the rubber tube 31 can rotate, ensuring smooth movement of the receiving tube 23 and the bottom cover 24.

[0030] In the specific configuration, two fixed plates 32 are spaced apart on the side of the pallet 30 away from the cylinder 26. A rotating column 33 is rotatably arranged between the two fixed plates 32. The axis of the rotating column 33 is parallel to the axis of the rotating column. The upper side of the rotating column 33 is flush with the upper side of the rubber tube 31. When the receiving tube 23 finishes discharging material and needs to return to the bottom of the discharge tube to receive material, the sliding plate 22 slides, driving the receiving tube 23 and the bottom cover 24 to move. The side of the bottom cover 24 contacts the rotating column 33. The receiving tube 23 continues to move, and the bottom cover 24 continues to rotate. When the receiving tube 23 is completely above the pallet 30, the bottom cover 24 engages with the lower end of the receiving tube 23.

[0031] The operating principle of the batching device for expansive concrete in this embodiment is as follows: When the receiving pipe 23 is located in the area directly above the pallet 30, it engages with the lower end of the receiving pipe 23, and the bottom surface of the bottom cover 24 contacts the rubber tube 31. The cylinder 26 drives the sliding plate 22 to slide, aligning the circular opening 221 with the discharge pipe 42. The expansive agent in the storage box 41 reaches the receiving pipe 23 and the circular opening 221 through the circular opening 221. Subsequently, the cylinder 26 drives the sliding plate 22 to slide towards the lower hopper 12, sealing the lower end of the discharge pipe 42. When the receiving pipe 23 completely leaves the area directly above the pallet 30, the bottom cover 24 loses its restraint and rotates downwards under gravity, causing the lower end of the receiving pipe 23 to lose its restraint, and the expansive agent inside falls into the lower hopper 12, subsequently reaching the concrete mixer. This ensures that each movement of the sliding plate 22 delivers a fixed amount of expansive agent to the lower hopper 12.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
