Description

Technical Field

[0001] This utility model relates to the field of unloading equipment technology, and in particular to a concrete anti-segregation unloading device. Background Technology

[0002] Segregation is a critical issue affecting the quality of concrete during unloading. Segregation leads to uneven distribution of concrete components, with coarse aggregates settling and cement paste rising, resulting in reduced concrete strength and durability, and in severe cases, even posing safety hazards to engineering structures.

[0003] Currently, during the concrete unloading process, the difference in movement speed between aggregates and slurry due to gravity can easily cause segregation when concrete is discharged from the unloading chute. Furthermore, existing unloading equipment often employs near-vertical unloading or simple horizontal receiving methods, making it difficult to control component separation during concrete flow and effectively buffering the impact of falling concrete. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention proposes a concrete anti-segregation dumping device.

[0005] The technical solution to the technical problem solved by this utility model is as follows:

[0006] This utility model proposes a concrete anti-segregation dumping device, including a base frame; a discharge trough, which is inclinedly arranged above the base frame, a motor is detachably installed at the bottom of the discharge trough, and at least one set of mixing discs is arranged inside the discharge trough, with the mixing discs being drivenly connected to the motor.

[0007] Preferably, the mixing plate is detachably connected to several sets of mixing rollers.

[0008] Preferably, the mixing plate has several sets of first threaded holes, and double-ended bolts are connected in the first threaded holes. The mixing roller is inserted above the double-ended bolts and fixed to the double-ended bolts by nuts.

[0009] Preferably, the stirring plate has several sets of turbulence grooves.

[0010] Preferably, the motor output is connected to a rotating shaft, which passes through the bottom of the unloading trough through a sealed bearing and is placed inside the unloading trough. Both the rotating shaft and the mixing plate have horizontal through holes. A fixing bolt passes through the two through holes and is connected to a nut to fix the turntable to the rotating shaft.

[0011] Preferably, the unloading trough includes a bottom plate, with the motor and the mixing plate respectively installed on the upper and lower sides of the bottom plate, and the left and right sides of the bottom plate are respectively connected to the enclosures, which are arc-shaped.

[0012] Preferably, the base frame includes two sets of symmetrical protective side frames, and several sets of support beams are connected inside the protective side frames and between the two sets of protective side frames.

[0013] Preferably, a support plate is provided on one side of the base frame, and a lifting component is connected to the support plate. The top of the lifting component is hinged to the bottom of the unloading chute. A tray is detachably connected to the other side of the base frame, and the top of the tray abuts against the other side of the unloading chute.

[0014] Preferably, the protective side frame has several sets of vertically arranged through holes on one side, and the support plate has second threaded holes on both sides. The two sets of positioning bolts pass through the through holes on both sides and are threaded into the corresponding second threaded holes to position the support plate at the designed height.

[0015] Preferably, the bottom of the pallet is connected to an auxiliary chute, which is arranged at an angle to receive concrete discharged from the buffer unloading chute.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] 1. In this utility model, a rotatable mixing disc is provided in the unloading trough. The mixing disc disturbs the concrete being unloaded in the unloading trough, continuously remixing the coarse aggregate, fine aggregate and cement paste evenly, breaking the possible stratification trend, and maintaining good uniformity of the concrete during the unloading process, thus avoiding segregation to a certain extent.

[0018] 2. In this utility model, a detachable stirring roller is provided on the baffle plate. The stirring roller can agitate the concrete additionally when it is poured out, which helps to break up any agglomerates or blocky structures that may form inside the concrete.

[0019] 3. In this utility model, the two sides of the unloading chute are connected by lifting components and a support plate to form an adjustable structure, which can adjust the inclination of the unloading chute according to different construction needs or unloading positions, and ensure that the unloading chute remains balanced during the unloading process, thereby improving overall safety.

[0020] 4. In this utility model, an auxiliary chute is provided at the output end of the unloading chute. The auxiliary chute constitutes a receiving and buffering channel for concrete unloading. It can receive the falling concrete at a gentle angle, effectively reduce the impact force of the concrete, and avoid segregation caused by the separation of coarse aggregate and mortar due to the excessive tilt angle of the unloading chute.

[0032] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0034] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figures 1 to 6 As shown in the figure, this embodiment proposes a concrete anti-segregation dumping device, which includes a base frame 1, a discharge trough 2 on the base frame 1, the discharge trough 2 being inclinedly arranged above the base frame 1, a detachable motor 3 being arranged at the bottom of the discharge trough 2, and at least one set of mixing discs 4 being arranged inside the discharge trough 2, the mixing discs 4 being drivenly connected to the motor 3, driving the mixing discs 4 to rotate inside the discharge trough 2, thereby disturbing the concrete in the discharge trough 2 and keeping the various components in the concrete in a uniformly mixed state.

[0036] During the tilting process, the concrete is subjected to gravity, impact, and other forces. Coarse aggregate tends to sink while fine aggregate and cement paste tend to float, leading to segregation. By agitating the concrete in the unloading trough 2 with the mixing pan 4, the coarse aggregate, fine aggregate, and cement paste can be continuously and evenly remixed, breaking the potential segregation trend and ensuring that the concrete maintains good uniformity during unloading, thus avoiding segregation to a certain extent.

[0037] In some embodiments, in order to further improve the uniformity of concrete in the unloading trough 2 and prevent segregation, a number of sets of mixing rollers 5 are detachably provided on the mixing pan 4. The mixing rollers 5 can perform additional agitation on the concrete when it is dumped and discharged, which helps to break up any agglomerates or blocky structures that may form inside the concrete.

[0038] Furthermore, several sets of first threaded holes 6 are provided on the mixing plate 4. Double-headed bolts are connected in the first threaded holes 6. The aforementioned mixing roller 5 is inserted above the double-headed bolt 7 and is threaded to the other end of the double-headed bolt 7 through a nut, thereby fixing the mixing roller 5 to the double-headed bolt 7. Preferably, two sets of nuts are provided so that the two nuts generate a continuous and interactive pressure, thereby achieving the purpose of preventing loosening.

[0039] Compared to the conventional method of directly screwing the threaded post at the bottom of the mixing roller 5 into the first threaded hole 6, the above design has significant advantages. For example, when the mixing roller 5 is disassembled and replaced, the double-ended bolt 7 remains inside the first threaded hole 6, effectively preventing the direct exposure of the first threaded hole 6. Concrete entering the threaded hole makes it difficult to clean, and residual concrete can cause blockage or damage to the first threaded hole 6. This design avoids damage to the first threaded hole 6 that could render the entire mixing disc 4 unusable, thus extending its overall service life.

[0040] In some embodiments, the mixing disc 4 has a frustum-shaped structure and several sets of turbulence-inducing grooves 8 are formed on it. The design of the turbulence-inducing grooves 8 creates a protrusion above the mixing disc 4, similar to a blade, which propels the concrete flow in a unique way. During the rotation of the mixing disc 4, the turbulence generated by the turbulence-inducing grooves 8 continuously disrupts the distribution of particles within the concrete. When the concrete flows under the propulsion of the turbulence-inducing grooves 8, larger-diameter sand and gravel particles do not easily sink due to gravity, and smaller-diameter cement particles do not float to the surface. All components remain in a dynamic mixing state, effectively suppressing segregation.

[0041] In some embodiments, the output of the motor 3 is connected to a rotating shaft 9. The rotating shaft 9 passes through the bottom of the unloading trough 2 via a sealed bearing 19, with its upper part positioned inside the unloading trough 2. Waterproof sealing is applied to the contact points between the sealed bearing 19, the bottom of the unloading trough 2, and the rotating shaft 9 to prevent concrete seepage from the unloading trough 2. Both the rotating shaft 9 and the mixing disc 4 have horizontally arranged through holes 10. Specifically, the through holes 10 are located between two opposing turbulence channels. Fixing bolts 11 pass through both through holes 10 and are connected to nuts to fix the disc to the rotating shaft 9. Preferably, to prevent the nuts from loosening, two nuts are provided on the fixing bolts 11, thereby preventing loosening and ensuring that the mixing disc 4 remains fixedly connected to the rotating shaft 9 during rotation. This ensures the continuous and stable operation of the unloading process and effectively improves the safety and reliability of the equipment.

[0042] In some embodiments, the unloading chute 2 includes a bottom plate 21, with the aforementioned motor 3 and mixing disc 4 respectively installed on the upper and lower sides of the bottom plate 21. Enclosures 22 are connected to the left and right sides of the bottom plate 21, and the enclosures 22 have an arc-shaped structure. The special structure of the enclosures 22 can form a buffer effect with the arc surface, guiding the flow direction of the concrete, dispersing the impact force generated by the concrete, and greatly preventing concrete from splashing out during mixing, thus protecting the surrounding environment. Simultaneously, an observation port can be formed at the top, providing operators with a convenient observation channel to monitor the concrete unloading status inside the unloading chute 2 in real time.

[0043] In some embodiments, the base frame 1 includes two sets of symmetrical protective side frames 101, and several sets of support beams 102 are connected between the protective side frames 101 and the two protective side frames 101; on one side (left side) of the base frame 1, a support plate 12 is provided between the two protective side frames 101, and a lifting assembly 13 is connected to the support plate 12. The lifting assembly 13 preferably adopts a hydraulic telescopic rod, and the top of the lifting assembly 13 is hinged to the bottom of the unloading chute 2; a pallet 14 is detachably connected to the other side (right side) of the base frame 1, and the top of the pallet 14 abuts against the other side (right side) of the unloading chute 2.

[0044] In this design, the height of one side of the unloading trough 2 can be adjusted by the lifting component 13 on the left side, which can maintain stability during the lifting process and facilitate quick adjustment of the height of the unloading trough 2 according to different construction needs or unloading positions. The right side is equipped with a detachable support plate 14, and a rubber pad 18 is set on the top of the support plate 14, which abuts against the bottom of the unloading trough 2. The lifting component 13 and the support plate 14 form a two-point support structure for the unloading trough 2, ensuring that the unloading trough 2 always maintains balance during the mixing and unloading process, and improving the overall safety.

[0045] Furthermore, several sets of vertically arranged through holes 15 are provided on one side (right side) of the protective frame, and second threaded holes 16 are provided on both sides of the support plate 14. Two sets of positioning bolts pass through the through holes 15 on both sides and are threaded into the corresponding second threaded holes 16 to position the support plate 14 at the designed height. This design provides flexibility in adjusting the height of the support plate 14. According to the actual construction scenario requirements, the support plate 14 can be adjusted to a suitable height and then re-fixed by quickly removing the positioning bolts, thereby achieving the purpose of adjusting the height of the output part of the unloading chute 2 and reducing problems such as inconvenience in unloading and concrete spillage caused by unsuitable height.

[0046] In some embodiments, an auxiliary chute 17 is fixedly connected to the bottom of the pallet 14. The auxiliary chute 17 is arranged at an incline to receive and buffer the concrete discharged from the unloading chute 2. When the incline angle of the unloading chute 2 is too high, the concrete will be subjected to a large impact force during its fall, causing the coarse aggregate and mortar to separate. To avoid this situation, the auxiliary chute 17 is set up to form a receiving and buffering channel for concrete unloading. It can receive the falling concrete at a gentle angle, effectively reducing the impact force of the concrete and avoiding the collision and segregation phenomenon caused by the direct fall of materials.

[0047] In some construction scenarios, concrete pouring needs to be continuous, and the pouring location may dynamically change due to project requirements. This necessitates that the concrete anti-segregation dumping device possess flexible mobility to evenly deliver concrete to designated areas. To meet this practical need, lockable casters are installed at the bottom of the base frame 1, enabling 360-degree free turning, smooth movement, and self-locking. Since this is existing technology, it will not be elaborated upon further. By manipulating the casters, operators can quickly and accurately adjust the base frame position, allowing the device to adapt to the changing needs of different pouring points. This ensures uniform concrete pouring even in complex working environments, significantly improving construction efficiency and pouring quality.

[0048] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
