Quantitative batching equipment for concrete mixing

Abstract

This utility model discloses a quantitative batching device for concrete mixing, belonging to the field of concrete processing technology. It includes a support frame with a connecting frame fixedly connected to it. Four hoppers are fitted inside the connecting frame, and solenoid valves are installed at the outlets of the hoppers. A moving device is fixedly connected to the outside of the support frame. In this utility model, when quantitative addition is required for concrete mixing, each material is loaded into its independent hopper. The operator activates the solenoid valve linked to the electronic scale via the control panel, causing the material to fall from the corresponding hopper into the weighing pan. When the electronic scale detects that the material weight has reached a preset value, it sends real-time data feedback to the control panel, triggering an electric push rod. The electric push rod drives a rotating shaft via an extension rod, causing symmetrically arranged push blocks to move linearly, pushing the pan to tilt along the pivot point of the rotating plate, thereby introducing precisely measured material into the mixing tank, completing the automated feeding process.

Description

Technical Field

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

[0002] Concrete is a composite material made by mixing cement, aggregates (such as sand and stone) and water in a certain proportion and hardening it. It has the characteristics of high compressive strength and good durability and is widely used in engineering fields such as construction, bridges, and roads. During the preparation process, it is necessary to ensure that the components are mixed evenly to achieve the strength and performance required by the design. Insufficient mixing may lead to uneven concrete quality, affecting the load-bearing capacity and durability of the final structure.

[0003] In the traditional concrete batching process, manual quantitative feeding is usually required. This method not only increases the complexity of operation but also reduces production efficiency, leading to a longer processing cycle. Manual intervention is not only prone to introducing errors but may also affect the accuracy of batching and the uniformity of mixing, thus adversely affecting the final performance of the concrete.

[0004] Based on this, the present invention designs a quantitative batching device for concrete mixing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the traditional concrete batching process, manual quantitative feeding is usually required. This method not only increases the complexity of operation and reduces production efficiency, but also prolongs the entire processing cycle. Manual intervention is not only prone to introducing errors, but may also affect the accuracy of batching and the uniformity of mixing, thus adversely affecting the final performance of concrete. Therefore, a quantitative batching device for concrete mixing is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quantitative batching device for concrete mixing includes a support frame, a connecting frame fixedly connected to the support frame, four hoppers being fitted inside the connecting frame, a solenoid valve being installed at the discharge port of each hopper, a moving device fixedly connected to the outside of the support frame, a weighing device fixedly connected to the moving device, and a control panel fixedly connected to one side of the moving device.

[0008] The weighing device includes an electronic scale with a support plate installed on it, and a material tray for easy pouring of materials is provided on the support plate.

[0009] As a further description of the above technical solution:

[0010] The weighing device also includes a pin connector, which is fixedly connected to the electronic scale. An electric push rod is fixedly connected to the outside of the pin connector. An extension rod is fixedly connected to the output end of the electric push rod. A rotating shaft is connected through the extension rod. Push blocks are fixedly connected to both ends of the rotating shaft. The push blocks are fixedly connected to the lower surface of the material tray. Rotating rods are fixedly connected to both sides of the support plate. A rotating plate is sleeved on the rotating rod. The rotating plate is fixedly connected to the lower surface of the material tray.

[0011] As a further description of the above technical solution:

[0012] The support plate has a long groove, and the electric push rod is movably connected in the long groove.

[0013] As a further description of the above technical solution:

[0014] The lower surface of the electronic scale is fixedly connected to a movable block, and the movable block has symmetrically opened grooves.

[0015] As a further description of the above technical solution:

[0016] The mobile device includes two mounting plates. The control panel is mounted on one side of one of the mounting plates. The two mounting plates are symmetrically mounted outside the support frame. A frame is fixedly connected to one side of one of the mounting plates. A drive motor is fixedly connected to one side of the frame. The drive motor is fixedly connected to one of the mounting plates. A reciprocating screw is fixedly connected to the output end of the drive motor. The reciprocating screw is rotatably connected inside the frame. A threaded cap is fitted onto the reciprocating screw.

[0017] As a further description of the above technical solution:

[0018] The movable block is fixedly connected to the upper surface of the threaded cap, the cross-section of which is rectangular, and one side of the rectangle overlaps the frame.

[0019] As a further description of the above technical solution:

[0020] Two sliding rods are fixedly connected inside the two mounting plates, and the grooves are slidably connected to the outside of the sliding rods.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, when it is necessary to add a quantitative amount of material during concrete mixing, each material is loaded into an independent hopper. The operator activates the solenoid valve linked to the electronic scale through the control panel, so that the material falls from the corresponding hopper into the weighing pan. When the electronic scale detects that the weight of the material has reached the preset value, it feeds the data back to the control panel in real time, triggering the electric push rod to move. The electric push rod drives the rotating shaft through the extension rod, which drives the symmetrically arranged push blocks to move linearly, pushing the pan to tilt along the pivot point of the rotating plate, thereby introducing the precisely measured material into the mixing tank and completing the automated feeding.

[0023] 2. In this utility model, after the drive motor starts, it drives the reciprocating lead screw to rotate, causing the moving block equipped with the threaded cap to move axially. The moving block is rigidly connected to the electronic scale. The displacement of the electronic scale is used to accurately position it under the hoppers of different materials, so as to realize the sequential weighing and feeding of different materials by the system. This modular design ensures the precise control of the proportion of various materials and the process-oriented operation. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 ,

[0032] First embodiment:

[0033] This utility model provides a technical solution: a quantitative batching device for concrete mixing, including a support frame 1, a connecting frame 2 fixedly connected to the support frame 1, four hoppers 3 clamped inside the connecting frame 2, a solenoid valve 4 installed at the discharge port of the hoppers 3, a moving device 5 fixedly connected to the outside of the support frame 1, a weighing device 6 fixedly connected to the moving device 5, and a control panel 7 fixedly connected to one side of the moving device 5.

[0034] The weighing device 6 includes an electronic scale 601, on which a support plate 602 is mounted, and on which a material tray 603 is provided for easy pouring of materials.

[0035] Specifically, such as Figure 2-4 As shown, the weighing device 6 also includes a pin connector 604, which is fixedly connected to the electronic scale 601. An electric push rod 605 is fixedly connected to the outside of the pin connector 604. An extension rod 606 is fixedly connected to the output end of the electric push rod 605. A rotating shaft 607 is connected through the extension rod 606. Push blocks 608 are fixedly connected to both ends of the rotating shaft 607. The push blocks 608 are fixedly connected to the lower surface of the material tray 603. The symmetrically arranged push blocks 608 are rigidly fixed to the lower surface of the material tray 603, forming a dual-point synchronous drive structure. When the rotating shaft 607 drives the push blocks 608 to make linear movements, the balanced thrust generated by the two push blocks 608 enables the material tray 603 to achieve tilting around the rotating rod 609 without deflection, effectively preventing material spillage. This design not only improves the stability of the tilting action, but also reduces the local wear between the rotating plate 610 and the rotating rod 609 through the action of the couple.

[0036] Rotating rods 609 are fixedly connected to both sides of the support plate 602. A rotating plate 610 is sleeved on the rotating rods 609. The material tray 603 forms a rotational hinge with the rotating rods 609 on the support plate 602 through the rotating plate 610. The sleeve structure achieves self-centering function by utilizing the gap fit between the rods while ensuring free rotation. This design enables the material tray 603 to maintain the stability of the rotation axis when subjected to asymmetrical material loads, avoiding wear or jamming of the sealing surface due to eccentric force.

[0037] The rotating plate 610 is fixedly connected to the lower surface of the material tray 603. The support plate 602 has a long groove, and the electric push rod 605 is movably connected in the long groove. The lower surface of the electronic scale 601 is fixedly connected to the moving block 611, and the moving block 611 has symmetrical grooves.

[0038] During operation, when quantitative addition is required for concrete mixing, each material is loaded into an independent hopper 3. The operator then activates the solenoid valve 4, which is linked to the electronic scale 601, via the control panel 7. This causes the material to fall from the corresponding hopper 3 into the weighing pan 603. When the electronic scale 601 detects that the material weight has reached the preset value, it sends the data back to the control panel 7 in real time, triggering the electric push rod 605. The electric push rod 605 drives the rotating shaft 607 via the extension rod 606, causing the symmetrically arranged push blocks 608 to move linearly. This pushes the pan 603 to tilt along the pivot point of the rotating plate 610, thereby introducing the precisely measured material into the mixing tank and completing the automated feeding process.

[0039] Second embodiment:

[0040] Specifically, such as Figure 2 As shown, the moving device 5 includes two mounting plates 51. The control panel 7 is installed on one side of one of the mounting plates 51. The two mounting plates 51 are symmetrically installed outside the support frame 1. A frame 52 is fixedly connected to one side of one of the mounting plates 51. A drive motor 53 is fixedly connected to one side of the frame 52. The drive motor 53 is fixedly connected to one of the mounting plates 51. A reciprocating screw 54 is fixedly connected to the output end of the drive motor 53. The reciprocating screw 54 is rotatably connected inside the frame 52. A threaded cap 55 is sleeved on the reciprocating screw 54. The threaded cap 55 with a rectangular cross section and the reciprocating screw 54 form a sliding-rotation composite motion pair. Its contact surface overlaps with the frame 52 to form a guiding constraint, which not only ensures the straightness of the axial movement, but also disperses the radial load in the transmission process through surface contact. This kind of cooperation has higher torsional stiffness than the traditional threaded transmission, which can avoid the positioning drift problem caused by inertia during the displacement of the electronic scale 601.

[0041] The movable block 611 is fixedly connected to the upper surface of the threaded cap 55. The cross-section of the threaded cap 55 is set as a rectangle, and one side of the rectangle overlaps the frame 52. Two slide rods 612 are fixedly connected inside the two mounting plates 51, and the groove is slidably connected to the outside of the slide rods 612.

[0042] During operation, after the drive motor 53 starts, it drives the reciprocating screw 54 to rotate, causing the moving block 611 equipped with the threaded cap 55 to move axially. The moving block 611 is rigidly connected to the electronic scale 601. Through the displacement of the electronic scale 601, it is accurately positioned below the material hoppers 3 of different materials, realizing the sequential weighing and feeding of different materials by the system. This modular design ensures the precise control of the proportion of various materials and the streamlined operation.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
