Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction engineering technology, specifically to a discharge port device for a concrete mixer truck used in construction engineering. Background Technology
[0002] In construction engineering, concrete mixer trucks are important equipment for concrete transportation and on-site pouring. The performance of their discharge port devices directly affects construction efficiency, concrete quality, and construction safety.
[0003] Traditional concrete mixer truck discharge ports have relatively simple structures and are usually manually or semi-automatically controlled. They lack the ability to monitor and dynamically adjust the discharge speed in real time. In actual construction, due to factors such as concrete mix ratio, ambient temperature, and transportation distance, the discharge speed and discharge volume are often unstable. This can easily lead to problems such as excessively fast discharge resulting in concrete waste and untimely pumping, or excessively slow discharge affecting the construction rhythm. To address these issues, we propose a discharge port device for concrete mixer trucks used in construction projects. Utility Model Content
[0004] The purpose of this utility model is to provide a discharge port device for concrete mixer trucks used in construction projects, in order to solve the problems mentioned in the background art. The traditional discharge port structure of mixer trucks is relatively simple, usually controlled manually or semi-automatically, and lacks the ability to monitor and dynamically adjust the discharge speed in real time. In actual construction, due to the influence of factors such as concrete mix ratio, ambient temperature, and transportation distance, the discharge speed and discharge volume are often unstable, which can easily lead to problems such as excessively fast discharge resulting in concrete waste and untimely pumping, or excessively slow discharge affecting the construction rhythm.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a discharge port device for a concrete mixer truck in construction engineering, comprising: a mixer truck; It also includes: a monitoring device, which is set on one side of the mixer truck's discharge port and is used to detect the speed at which the mixer truck discharges concrete; The regulating mechanism is located on one side of the mixer truck's discharge port. The regulating mechanism works in conjunction with the monitoring mechanism to adaptively adjust the concrete discharge speed at the discharge port based on the concrete discharge speed of the mixer truck fed back by the monitoring mechanism. The monitoring mechanism includes a first fixed box fixedly connected to one side of the mixer truck, a first rotating rod rotatably connected inside the mixer truck, and a baffle fixedly connected to the outside of the first rotating rod; The adjustment mechanism includes two second fixed boxes fixedly connected to one side of the mixer truck. Gears are rotatably connected to the inner sides of the two second fixed boxes. A first rack is meshed with the bottom of the gears, and a second rack is meshed with the top of the gears.
[0006] The first fixed box has two rotatably connected second rotating rods on both sides. The outer sides of the two second rotating rods and the outer side of the first rotating rod are fixedly connected to pulleys. The outer sides of the two pulleys are provided with belts. One end of the second rotating rod is fixedly connected to a disc. The two discs are fixedly connected to a driving rod.
[0007] A torsion spring is fixedly connected between one side of the pulley and one side inside the first fixed box.
[0008] The first fixed box has a second conductive block fixedly connected to one side of its inner side. The first fixed box has a first sliding groove inside. A hollow plate is slidably connected to the inner side of the first sliding groove. The driving rod is located inside the hollow plate. A first conductive block is fixedly connected to one side of the hollow plate. The bottom of the hollow plate is located in the first sliding groove and is fixedly connected to a first spring. The bottom of the first spring is fixedly connected to the first fixed box.
[0009] A second spring is fixedly connected between one side of the first rack and one side inside the second fixed box. A magnet is fixedly connected to the side of the first rack away from the second spring. A first electromagnet is fixedly connected to one side inside the second fixed box. A blocking cover is fixedly connected to one side of the second rack.
[0010] In this case, the magnetic poles of the first electromagnet and the magnet facing each other are opposite.
[0011] The second fixed box has a second sliding groove inside that cooperates with the first rack, and a third sliding groove inside that cooperates with the second rack.
[0012] This utility model has at least the following beneficial effects: By setting up a monitoring mechanism, the discharge speed and quantity of concrete at the mixer truck's discharge port can be monitored in real time via mechanical transmission. When the discharge speed and quantity are excessive, the contact area between the first and second conductive blocks is increased, thereby increasing the conductive power. The discharge speed and quantity of concrete are then fed back based on the magnitude of the conductive power. By setting up an adjustment mechanism, the information fed back by the monitoring mechanism can be received. Driven by the magnetic repulsion between the first electromagnet and the magnet, combined with the linkage structure of gears, the first rack and the second rack, the opening of the discharge port can be automatically adjusted according to the change in discharge speed, realizing dynamic closed-loop control. The information is fed back to the mixer truck through the monitoring mechanism, so that the mixer truck and the adjustment mechanism can work together to adjust the discharge speed and quantity of concrete, ultimately preventing concrete waste or untimely delivery.

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example 1
[0017] Please see Figures 1 to 6 This utility model provides a technical solution: a discharge port device for a concrete mixer truck in construction engineering, comprising: a mixer truck 1; It also includes: monitoring mechanism 2, which is set on one side of the discharge port of the mixer truck 1 and is used to detect the speed at which the mixer truck 1 discharges concrete; Adjustment mechanism 3 is located on one side of the discharge port of mixer truck 1. Adjustment mechanism 3 works in conjunction with monitoring mechanism 2 to adjust the concrete discharge speed at the discharge port of mixer truck 1 based on the concrete discharge speed fed back by monitoring mechanism 2.
[0018] By setting up monitoring mechanism 2, the discharge speed and quantity of concrete at the discharge port of mixer truck 1 can be monitored in real time through mechanical transmission. When the discharge speed and quantity are excessive, the contact area between the first conductive block 211 and the second conductive block 212 is increased, thus increasing the conductive power. The discharge speed and quantity of concrete are fed back by the magnitude of the conductive power. By setting up adjustment mechanism 3, the information fed back by monitoring mechanism 2 can be received. Driven by the magnetic repulsion between the first electromagnet 37 and the magnet 38, combined with the linkage structure of gear 310, first rack 33 and second rack 34, the opening of the discharge port can be automatically adjusted according to the change of discharge speed, realizing dynamic closed-loop control. The information is fed back to mixer truck 1 through monitoring mechanism 2, so that mixer truck 1 and adjustment mechanism 3 cooperate to adjust the discharge speed and quantity of concrete, ultimately preventing concrete waste or untimely delivery.
[0019] The monitoring mechanism 2 includes a first fixed box 21 fixedly connected to one side of the mixer truck 1. A first rotating rod 23 is rotatably connected inside the mixer truck 1. A baffle 24 is fixedly connected to the outside of the first rotating rod 23. Second rotating rods 26 are rotatably connected to both sides inside the first fixed box 21. Pulleys 25 are fixedly connected to the outside of both the second rotating rods 26 and the outside of the first rotating rod 23. A belt is provided on the outside of the two pulleys 25. A disc 27 is fixedly connected to one end of the second rotating rod 26. A driving rod 28 is fixedly connected between the two discs 27. During use, concrete is discharged from the discharge port of the mixer truck 1. The discharged concrete drives the first rotating rod 23 to rotate through the baffle 24. The rotating first rotating rod 23 drives two pulleys 25. The pulleys 25 on the outer side of the two first rotating rods 23 drive the pulleys 25 on the outer side of the second rotating rod 26 through the belt. The rotating second rotating rod 26 drives the disc 27, which in turn drives the rod 28 to a position corresponding to the concrete discharge speed and discharge amount.
[0020] A torsion spring 213 is fixedly connected between one side of the pulley 25 and one side inside the first fixed box 21; When in use, when the pulley 25 on the outer side of the second rotating rod 26 rotates, the torsion spring 213 can be torn. When the material discharge stops, the torsion spring 213 can drive the baffle 24 to reset.
[0021] A second conductive block 212 is fixedly connected to one side of the inner side of the first fixed box 21. A first sliding groove 22 is opened inside the first fixed box 21. A hollow plate 29 is slidably connected to the inner side of the first sliding groove 22. A driving rod 28 is located inside the hollow plate 29. A first conductive block 211 is fixedly connected to one side of the hollow plate 29. The bottom of the hollow plate 29 is located in the first sliding groove 22 and is fixedly connected to a first spring 210. The bottom of the first spring 210 is fixedly connected to the first fixed box 21. In use, when the drive rod 28 moves, it slides inside the hollow plate 29, causing the drive rod 28 to move the hollow plate 29 upward. The upward-moving hollow plate 29 slides and is limited in the first slide groove 22, and stretches the first spring 210. When the hollow plate 29 moves upward, it can drive the second conductive block 212. When the concrete discharge speed and discharge volume are faster and more abundant, the contact area between the second conductive block 212 and the first conductive block 211 is larger, so that information can be fed back to the mixer truck 1 and the first electromagnet 37.
[0022] The adjusting mechanism 3 includes two second fixed boxes 31 fixedly connected to one side of the mixer truck 1. Gears 310 are rotatably connected to the inner sides of the two second fixed boxes 31. A first rack 33 is meshed with the bottom of the gear 310, and a second rack 34 is meshed with the top of the gear 310. A second spring 36 is fixedly connected between one side of the first rack 33 and one side inside the second fixed box 31. A magnet 38 is fixedly connected to the side of the first rack 33 away from the second spring 36. A first electromagnet 37 is fixedly connected to one side inside the second fixed box 31. A blocking cover 39 is fixedly connected to one side of the second rack 34. In use, the concrete discharged by the mixer truck 1 can push out the blocking cover 39, causing the moving blocking cover 39 to drive the second rack 34. The moving second rack 34 can drive the first rack 33 through the gear 310. The first rack 33 drives the magnet 38 to approach the first electromagnet 37 and stretches the second spring 36. According to the information fed back from the contact surface of the first conductive block 211 and the second conductive block 212, the larger the contact surface, the greater the discharge speed and discharge volume, which in turn makes the electromagnetic strength of the first electromagnet 37 greater and cooperates with the mixer truck 1 to reduce the discharge. Conversely, the feedback is fed back to the mixer truck 1 to control the increase of the discharge volume. The moving first rack 33 can drive the second rack 34 to move through the gear 310, thus allowing the concrete to pass through.
[0023] Example 2
[0024] like Figures 5 to 6 In this second embodiment, the other structures remain unchanged, but the difference from the first embodiment is: The magnetic poles of the first electromagnet 37 and the magnet 38 facing each other are opposite. When in use, when the first electromagnet 37 is energized, the energized first electromagnet 37 can attract the magnet 38 to come closer, thereby adjusting the discharge speed and discharge amount.
[0025] The interior of the second fixed box 31 is provided with a second sliding groove 32 that cooperates with the first rack 33, and the interior of the second fixed box 31 is provided with a third sliding groove 35 that cooperates with the second rack 34. When in use, the first electromagnet 37 attracts the magnet 38 to a close position, thereby enabling the first rack 33 to move and slide within the second groove 32, while the moving second rack 34 can slide within the third groove 35.
