Description

Technical Field

[0001] This utility model relates to the field of concrete pouring equipment technology, specifically to a concrete pouring device for auxiliary filling of exterior walls. Background Technology

[0002] In the construction of exterior walls of building projects, the concrete pouring of infill structural columns is a crucial step in ensuring the integrity of the wall structure and its seismic performance. Currently, there are two main construction methods commonly used in China: one is for concrete workers to pour concrete using hand tools, and the other is to use a concrete secondary structural column pouring conveyor.

[0003] When using hand tools for pouring concrete, relying on manual scooping and feeding is not only inefficient, but also prone to spillage during transportation and pouring, resulting in material waste. Furthermore, manual operation makes it difficult to precisely control the pouring speed and placement of the concrete, easily leading to excessively long pouring times. This affects the concrete's setting strength and molding quality, especially in complex areas such as door and window openings and wall / column joints, where insufficient vibration or aggregate segregation often results in defects such as honeycomb-like surfaces and hollow areas.

[0004] While the concrete secondary structural column pouring conveyor used in another method improves pouring efficiency to some extent, it requires the purchase of specialized equipment, increasing project costs. In addition, this equipment requires dedicated personnel to transport concrete and operate the equipment, leading to an increase in the number of workers. Furthermore, the equipment is large and difficult to move in confined working environments, and its subsequent cleaning and maintenance are also more complicated, making it difficult to meet the construction needs of small and medium-sized projects or scattered structural columns.

[0005] The two existing construction methods face contradictions between efficiency and quality, and between cost and ease of operation. There is an urgent need for an auxiliary pouring device that can balance construction efficiency, quality control and economy, in order to solve the problems of serious concrete waste, high dependence on manual labor and high equipment costs in traditional processes, and meet the technical requirements of modern building construction for high efficiency, precision and economy. Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides an auxiliary concrete pouring device for filling external walls, which solves the technical problems of low efficiency of manual pouring and high cost and poor adaptability of mechanized equipment in the prior art.

[0007] According to one aspect, at least one embodiment of the present invention provides an auxiliary concrete pouring device for filling exterior walls, comprising:

[0008] A concrete hopper, wherein the concrete hopper is provided with a mixing chamber for holding concrete to be poured, and the outer wall of the concrete hopper is provided with a main discharge port for connecting the mixing chamber and the outside.

[0009] A sliding stop is provided, which is slidably mounted on the concrete hopper. The sliding stop has a constricted pipe, one end of which has a centralized discharge port, and the other end of which matches the shape of the main discharge port. The sliding stop is configured such that: when it slides downward, the mixing chamber is connected to the outside through the main discharge port, the constricted pipe, and the centralized discharge port in sequence, in order to reduce the discharge cross-sectional area; when the sliding stop slides upward, the constricted pipe is disconnected from the mixing chamber, and the mixing chamber is directly connected to the outside through the main discharge port.

[0010] For example, at least one embodiment of this disclosure provides a concrete pouring device for auxiliary filling of exterior walls, wherein vertical guide grooves are provided on both side walls of the main discharge port, and further includes:

[0011] A baffle is provided with symmetrical sliding parts on both sides. The baffle slides up and down and swings in the vertical guide groove through the sliding parts. The baffle is configured to block or unblock the main discharge port after swinging and sliding.

[0012] For example, at least one embodiment of this disclosure provides an auxiliary concrete pouring device for filling exterior walls. The lower end of the sliding stop is hinged to a connecting rod, and the other end of the connecting rod is hinged to the baffle. The sliding stop is configured such that, after sliding upward, it drives the baffle to slide upward and swing outward through the connecting rod to open the main discharge port; after sliding downward, it drives the baffle to swing inward through the connecting rod to close the main discharge port, and after the sliding stop continues to slide downward, it drives the baffle to continue to slide downward, opening the main discharge port again, so that the main discharge port is connected to the constricted pipe, which is used to keep the main discharge port closed during the process of the constricted pipe moving to connect with the main discharge port.

[0013] For example, at least one embodiment of this disclosure provides a concrete pouring device for auxiliary filling of exterior walls, wherein anti-sway blocks are provided on the inner sidewalls of both sides of the main discharge port. The anti-sway blocks are configured such that after the baffle swings inward, it abuts against the anti-sway blocks to limit the baffle from continuing to swing inward. When the baffle abuts against the anti-sway blocks, the baffle is in a vertical state. When the baffle slides down, the surface of the baffle slides against the anti-sway blocks.

[0014] For example, at least one embodiment of this disclosure provides a concrete pouring device for auxiliary filling of exterior walls, in which a first elastic member is provided on the bottom wall of the vertical guide groove, and a top block is provided at the other end of the first elastic member. After the baffle slides down naturally, the sliding part abuts against the top block, and the first elastic member can push the sliding part through the top block to limit the baffle from sliding down naturally.

[0015] For example, at least one embodiment of this disclosure provides an auxiliary concrete pouring device for filling exterior walls, which further includes:

[0016] A guide plate is horizontally slidably disposed on the bottom wall of the main discharge port. The guide plate is configured to extend out of the main discharge port after horizontal sliding. A guide path is formed between the guide plate and the baffle. After the baffle swings inward, its lower end can slide against the guide plate to retract the guide plate into the main discharge port.

[0017] For example, at least one embodiment of this disclosure provides an auxiliary concrete pouring device for filling exterior walls, which further includes:

[0018] A screw conveyor is rotatably disposed within the mixing chamber. The screw conveyor rotates in both directions and is used for mixing or conveying concrete to the outside.

[0019] For example, at least one embodiment of this disclosure provides a concrete pouring device for auxiliary filling of exterior walls, which further includes a vehicle body, and the concrete hopper is detachably mounted on the vehicle body.

[0020] For example, at least one embodiment of this disclosure provides a concrete pouring device for auxiliary filling of exterior walls, wherein the concrete hopper is detachably provided with an installation frame, the main discharge port is disposed on the installation frame, and the sliding stop is slidably disposed on the installation frame.

[0021] For example, at least one embodiment of this disclosure provides a concrete pouring device for auxiliary filling of exterior walls, wherein a swing frame is oscillating on the vehicle body, and the concrete bucket is disposed on the swing frame, and the swing frame swings to drive the concrete bucket to swing synchronously.

[0022] The beneficial effects of the embodiments of this utility model are as follows:

[0023] In this invention, the main discharge port of the concrete hopper and the narrowing pipe of the sliding stop form a switchable dual discharge channel structure. The discharge cross-sectional area is controlled in stages by adjusting the position of the sliding stop. When precise pouring is required for complex areas such as door and window openings and wall / column joints, the sliding stop descends, connecting the narrowing pipe to the discharge path. The gradually narrowing channel of the narrowing pipe restricts the concrete flow, ensuring a stable flow rate from the main discharge port. This solves the problem of inaccurate control of pouring speed and landing point in manual operation, avoiding insufficient vibration or aggregate segregation due to flow rate fluctuations, thus reducing defects such as honeycomb, pitting, and hollow areas. When pouring large-area structural columns, the sliding stop rises, allowing the mixing chamber to discharge directly through the main discharge port. The large cross-sectional area channel meets the need for rapid concrete delivery. Compared to the discontinuous operation of manual scooping, continuous concrete discharge is achieved, significantly improving construction efficiency. The sliding stop and the concrete hopper are connected by a sliding rail and chute mechanism to form a modular adjustable component. This structure does not require special large equipment, which reduces the equipment purchase cost. Moreover, the overall device is small in size and light in weight, and is easy to move in narrow working environments, solving the problem of poor adaptability caused by the large size of existing mechanized equipment.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] like Figures 1-4 The diagram illustrates an auxiliary concrete pouring device for filling exterior walls according to an embodiment of the present invention, comprising two core structural parts: a concrete hopper 1 and a sliding stop 2. The concrete hopper 1 is a cavity structure with an open top, containing a mixing chamber 101 for holding the concrete to be poured. A main discharge port 102 is provided on the bottom outer wall of the mixing chamber 101. This main discharge port 102 is a rectangular through-hole structure, its length direction being consistent with the length direction of the concrete hopper 1. The sliding stop 2 is slidably connected to the outer wall of the concrete hopper 1 via a vertically arranged guide rail mechanism. The guide rail mechanism includes two parallel slide rails fixed to the outer wall of the concrete hopper 1. Slide grooves are provided on both sides of the sliding stop 2 to cooperate with the slide rails, enabling the sliding stop 2 to slide up and down along the height direction of the concrete hopper 1. A constricted pipe 201 is embedded in the middle area of ​​the sliding stop 2. The constricted pipe 201 is a tubular structure with a gradually narrowing internal channel cross-section. The shape of its input end port is completely matched with the total discharge port 102, forming a sealed mating area with surface contact. A centralized discharge port 202 is provided at the output end. The centralized discharge port 202 is a circular through hole with a diameter smaller than the minimum side length of the total discharge port 102. When the sliding stop 2 slides downward under the action of the driving mechanism, the input end of the narrowing pipe 201 is fully connected to the main discharge port 102. At this time, the concrete in the mixing chamber 101 is discharged sequentially through the main discharge port 102, the gradually narrowing channel of the narrowing pipe 201, and the centralized discharge port 202. The discharge flow rate is controlled by utilizing the cross-sectional area reduction effect of the narrowing pipe 201. When the sliding stop 2 slides upward to the highest position, the input end of the narrowing pipe 201 is completely disengaged from the main discharge port 102, and the mixing chamber 101 is directly connected to the outside through the exposed main discharge port 102, forming a large cross-sectional area discharge channel. The driving mechanism can be a manually operated screw and nut assembly or an electric push rod, the output end of which is connected to the back of the sliding stop 2 to provide sliding driving force.

[0037] The main discharge port 102 of the concrete hopper 1 and the narrowing pipe 201 of the sliding stop 2 form a switchable dual discharge channel structure. The discharge cross-sectional area can be controlled in stages by adjusting the position of the sliding stop 2. When precise pouring is required for complex parts such as door and window openings and wall column joints, the sliding stop 2 descends to connect the narrowing pipe 201 to the discharge path. The gradually narrowing channel of the narrowing pipe 201 restricts the flow of concrete, allowing it to be discharged from the main discharge port 202 at a stable flow rate. This solves the problem of inaccurate control of pouring speed and landing point in manual operation, and avoids insufficient vibration or aggregate segregation caused by flow rate fluctuations, thereby reducing defects such as honeycomb, pitting, and hollow areas. When pouring large-area structural columns, the sliding stop 2 rises to allow the mixing chamber 101 to discharge directly through the main discharge port 102. The large cross-sectional area channel meets the needs of rapid concrete delivery. Compared with the discontinuous operation of manual scooping, continuous concrete discharge is achieved, significantly improving construction efficiency. The sliding stop 2 is connected to the concrete hopper 1 via a sliding rail and groove mechanism, forming a modular adjustable assembly. This structure eliminates the need for specialized large equipment, reducing equipment purchase costs. Furthermore, the overall device is small in size and lightweight, allowing for easy movement in confined working environments, thus solving the problem of poor adaptability caused by the large size of existing mechanized equipment. The face-to-face sealing fit between the input end of the constricted pipe 201 and the main discharge port 102 ensures a tight seal when switching between the two discharge modes, preventing concrete spillage during channel switching and reducing material waste. The flexible switching of discharge modes through a mechanical structure replaces the uncertainty of traditional manual operation and the high cost of mechanized equipment. While ensuring construction quality, it reduces reliance on manual labor, meeting the economic and flexibility requirements of small and medium-sized projects and sporadic structural column construction.

[0038] In some examples, vertical guide grooves 103 are added to the side walls of the main discharge port 102. These vertical guide grooves 103 extend along the height direction of the concrete hopper 1 and penetrate the upper and lower edges of the main discharge port 102. Sliding parts 301 are symmetrically arranged on both sides of the baffle 3. Each sliding part 301 is a cylindrical sliding column protruding from the side of the baffle 3, and its outer diameter is adapted to the width of the vertical guide groove 103. The sliding part 301 is embedded in the vertical guide groove 103 and can slide up and down along the vertical track of the guide groove 103. Simultaneously, the contact interface between the sliding part 301 and the guide groove 103 is provided with a hemispherical groove and a convex ball mating structure, allowing the sliding part 301 to swing within the guide groove 103. When the baffle 3 is subjected to external force, its height position can be adjusted by sliding the sliding part 301 within the vertical guide groove 103. At the same time, the relative angle between the baffle 3 and the main discharge port 102 can be changed by swinging: when the main discharge port 102 needs to be closed, the baffle 3 is slid down along the guide groove 103 to below the main discharge port 102, and the baffle 3 is made to fit against the discharge end face of the main discharge port 102 by swinging; when the main discharge port 102 needs to be opened, the baffle 3 is slid up to above the main discharge port 102 and swings outward to remove the obstruction of the discharge channel.

[0039] The vertical guide grooves 103 on both sides of the main discharge port 102 and the sliding part 301 of the baffle 3 constitute a swingable sliding guide mechanism. The opening and closing control of the main discharge port 102 is achieved by the lifting, sliding and angular swinging of the baffle 3. When the sliding baffle 2 descends to connect the constricted pipe 201 to the discharge path, the baffle 3 can be swung to fit against the end face of the main discharge port 102, forming a sealed blockage of the main discharge port 102, ensuring that the concrete is discharged only through the centralized discharge port 202 of the constricted pipe 201, avoiding the disorder of discharge flow caused by the simultaneous opening of the two discharge channels; when the sliding baffle 2 rises to switch to direct discharge from the main discharge port 102, the baffle 3 is swung and slid up to the unblocked position, allowing the concrete to flow out quickly through the main discharge port 102 without obstruction. This structure achieves interlocked control of the discharge channel through mechanical linkage. Compared with the traditional manual method of sealing the discharge port, it significantly improves the reliability and convenience of switching the discharge mode, avoiding problems such as concrete leakage or inaccurate control of the discharge cross-sectional area caused by human error. At the same time, the spherical fit structure between the sliding part 301 of the baffle 3 and the vertical guide groove 103 allows the baffle 3 to be adjusted in a confined space, adapting to the control requirements of the discharge direction at different pouring positions. Especially when constructing in narrow areas such as door and window openings, the discharge angle can be adjusted by swinging the baffle 3, so that the concrete falls accurately to the target pouring position, further improving the pouring quality of complex parts and reducing the cost of secondary repairs due to landing point deviation.

[0040] In some examples, the lower ends of the sliding stop 2 are symmetrically hinged on both sides, connected to the baffle 3 via a connecting rod 4. The two ends of the connecting rod 4 are hinged to the lower end of the sliding stop 2 and the middle of the baffle 3, respectively, forming a mechanical linkage structure capable of transmitting motion. When the sliding stop 2 is driven to slide upwards, the connecting rod 4 drives the baffle 3 to slide upwards along the vertical guide groove 103 and swing outwards, causing the baffle 3 to move out of the obstruction range of the main discharge port 102, thus opening the main discharge port 102. When the sliding stop 2 slides downwards, the connecting rod 4 first drives the baffle 3 to swing inwards to fit against the end face of the main discharge port 102, forming a temporary closure. As the sliding stop 2 continues to slide downwards, the connecting rod 4 pushes the baffle 3 downwards along the guide groove 103. At this time, the constricted pipe 201 gradually connects with the main discharge port 102 until it is fully connected. Throughout the process, the hinged transmission of the connecting rod 4 ensures the coupling of the motion trajectories of the sliding stop 2 and the baffle 3, achieving the initial closure and subsequent connection of the main discharge port 102 when switching discharge channels.

[0041] The sliding stop 2 and the baffle 3 are mechanically linked by the connecting rod 4, utilizing the motion transmission characteristics of the hinged structure to achieve interlocked control of the discharge channel. When switching to direct discharge from the main discharge port 102, the connecting rod 4 drives the baffle 3 to slide upwards and swing open synchronously, ensuring that the main discharge port 102 is fully open to meet the high-flow-rate pouring requirements. When connecting to the narrowing pipe 201, the connecting rod 4 first drives the baffle 3 to close the main discharge port 102, and then drives it to move downwards to avoid it, so that the narrowing pipe 201 can accurately connect to the main discharge port 102. The "close first, then connect" action logic avoids the mixing problem caused by the simultaneous opening of the two channels, significantly improving the reliability of the discharge mode switching. The mechanical linkage of the connecting rod 4 does not require an additional control device. The action synchronization is achieved through rigid transmission, reducing the control complexity and failure risk of the device. At the same time, it maintains the temporary closed state of the main discharge port 102 during the channel switching process, effectively preventing concrete leakage and reducing material waste.

[0042] In some examples, anti-sway blocks 5 are fixedly installed on the inner sidewalls of both sides of the main discharge port 102. The anti-sway blocks 5 are rectangular block structures perpendicular to the sidewalls, with their height direction consistent with the extension direction of the vertical guide groove 103, and the inner end face of the anti-sway blocks 5 is on the same plane as the discharge end face of the main discharge port 102. When the baffle 3 is driven to swing inward by the connecting rod 4, its plate surface gradually approaches the inner sidewall of the main discharge port 102 until the baffle 3 reaches a vertical state, at which point the side of the baffle 3 abuts against the inner end face of the anti-sway blocks 5, forming a swing angle limit. At this time, the plate surface of the baffle 3 completely covers the discharge end face of the main discharge port 102, achieving a sealing and blocking effect. When the baffle 3 slides down the vertical guide groove 103, the surface of the baffle 3 and the inner end face of the anti-sway block 5 keep sliding contact. The anti-sway block 5 provides guiding support for the vertical movement of the baffle 3, ensuring that the baffle 3 maintains a vertical posture during the sliding process and avoiding the failure of the discharge channel seal due to the deviation of the swing angle.

[0043] The anti-sway block 5 on the inner wall of the main discharge port 102 and the baffle 3 form a composite structure of swing limiting and sliding guidance. Through physical contact, the swing angle of the baffle 3 is precisely controlled, ensuring it remains vertically sealed when the main discharge port 102 is closed, effectively preventing concrete leakage from the gap between the baffle and the discharge port. The anti-sway block 5 provides continuous sliding support during the downward movement of the baffle 3, ensuring that the movement trajectory of the baffle 3 is always perpendicular to the end face of the main discharge port 102, avoiding jamming or sealing failure due to tilting, and improving the smoothness of the discharge channel switching. This structure replaces complex control logic with mechanical limiting, achieving baffle 3 attitude control without additional power. Together with the vertical guide groove 103, it forms a stable motion guiding system, ensuring that the baffle 3 can reliably avoid the constricted pipe 201 when it connects to the main discharge port 102 without affecting channel connectivity. The setting of the anti-sway block 5 also indirectly improves the linkage accuracy of the sliding stop 2 and the baffle 3, so that the two maintain coordinated action during the switching of the discharge mode, reduce the need for manual intervention, and further reduce the risk of operational errors. It is especially suitable for complex construction scenarios with high frequency switching of discharge mode, and ensures the reliability and durability of the pouring device from the structural design level.

[0044] In some examples, a first elastic member 6 is fixedly connected to the bottom wall of the vertical guide groove 103, and the other end of the first elastic member 6 is connected to a top block 7. The top block 7 is located inside the vertical guide groove 103, and its width is adapted to the groove width of the guide groove 103. The top surface forms an arc surface structure that fits the outer circular surface of the sliding part 301. When the baffle 3 is not subjected to external force, it slides down the vertical guide groove 103 naturally under the action of gravity until the sliding part 301 contacts the arc surface of the top block 7. At this time, the first elastic member 6 is in a compressed state, and the top block 7 applies an upward pushing force to the sliding part 301. This pushing force is balanced with the gravity of the baffle 3, limiting the baffle 3 from continuing to slide down. When it is necessary to drive the baffle 3 to slide down, the sliding stop 2 applies a downward driving force to the baffle 3 through the connecting rod 4. This driving force is greater than the elastic force of the first elastic member 6, pushing the top block 7 to compress the first elastic member 6, so that the baffle 3 can continue to move down along the vertical guide groove 103.

[0045] The first elastic element 6 on the bottom wall of the vertical guide groove 103 and the top block 7 form an elastic limiting mechanism. The elastic pushing force counteracts the weight of the baffle 3, effectively preventing it from sliding down naturally due to gravity when not in operation, thus avoiding accidental opening of the main discharge port 102. Compared to traditional unrestrained structures, this reduces the risk of accidental opening of the discharge channel. The arc surface of the top block 7 forms a surface contact with the outer circular surface of the sliding part 301, limiting the natural sliding of the baffle 3 while providing a smooth guiding path for its active sliding, avoiding jamming problems caused by rigid limiting. The elastic buffering effect of the first elastic element 6 absorbs the impact force during the sliding process of the baffle 3, reducing frictional wear between the sliding part 301 and the vertical guide groove 103, and extending the service life of the components. This elastic limiting structure requires no additional control device and locks the position of the baffle 3 solely through mechanical elastic force. While ensuring the stability of the discharge channel, it reduces the maintenance cost and energy consumption of the device. It is especially suitable for construction scenarios involving high-altitude operations or bumpy environments, ensuring that the opening and closing state of the main discharge port 102 is not affected by external vibrations. From the structural design perspective, it improves the reliability and environmental adaptability of the pouring device.

[0046] In some examples, the bottom wall of the main discharge port 102 is provided with a horizontally extending guide rail structure. The guide ramp 8 slides horizontally along the width direction of the main discharge port 102 through a slider sliding engagement with the guide rail. The upper surface of the guide ramp 8 is an inclined plane, and its inclination angle matches the flow characteristics of concrete. When the baffle 3 is in a vertical state and located above the main discharge port 102, the guide ramp 8 slides outward along the guide rail under the action of the driving mechanism until it extends out of the main discharge port 102. At this time, a flow path 801 is formed between the upper surface of the guide ramp 8 and the inner side of the baffle 3. When the baffle 3 is driven by the connecting rod 4 to swing inward, the lower end of the baffle 3 contacts the end of the guide ramp 8 and applies a thrust, forcing the guide ramp 8 to retract into the main discharge port 102 along the guide rail until the baffle 3 completely covers the main discharge port 102.

[0047] The guide plate 8 and the baffle 3 form a dynamically adjustable guide path 801, achieving precise control of the discharge direction through horizontal sliding. When pouring into a specific area, the guide plate 8 extends out of the main discharge port 102, using its inclined surface to guide the concrete flow to the target position, avoiding splashing and landing point deviation caused by traditional free-fall pouring methods, thus improving pouring accuracy. When switching to the discharge mode of the constricted pipe 201, the swinging motion of the baffle 3 synchronously drives the guide plate 8 to retract, preventing interference with the docking process of the constricted pipe 201 and ensuring a smooth switch between the two discharge modes. The formation of the guide path 801 also constrains the concrete flow, reducing segregation and ensuring that the coarse aggregate and cement mortar remain uniformly mixed during the flow, improving the homogeneity of the cast body. In addition, the retractable design of the guide plate 8 allows it to be hidden inside the main discharge port 102 when not in use, effectively protecting the surface of the plate from impact damage and extending its service life.

[0048] In some examples, a screw conveyor 9 is installed inside the mixing chamber 101. The shaft of the screw conveyor 9 is rotatably connected to the front and rear side walls of the concrete hopper 1 via bearings, and its helical blades extend axially and cover most of the area of ​​the mixing chamber 101. One end of the screw conveyor 9 extends out of the concrete hopper 1 and is connected to a drive mechanism that can switch between forward and reverse rotation. When the screw conveyor 9 rotates forward, the helical blades push the concrete axially toward the main discharge port 102, generating the power to transport the concrete to the outside. When the screw conveyor 9 rotates in reverse, the pushing direction of the helical blades is opposite to the discharge direction, and the concrete circulates within the mixing chamber 101, achieving the function of mixing the concrete.

[0049] The bidirectional rotation of the screw conveyor 9 integrates the mixing and conveying of concrete within the mixing chamber 101. During forward rotation, the pushing action of the screw blades allows the concrete to flow through the discharge channel at a stable velocity. Compared to traditional gravity discharge, this increases the pouring speed and effectively avoids pipe blockage caused by concrete segregation. During reverse rotation, the screw blades continuously mix the concrete, preventing coarse aggregate sedimentation, maintaining concrete homogeneity, and significantly improving the strength consistency of the cast. This structure achieves both functions with a single power source, simplifying the device structure and reducing equipment costs and maintenance complexity. Furthermore, the axial pushing action of the screw conveyor 9 applies pressure to the concrete. When using the constricted pipe 201 for precise pouring, this enhances the spray distance and accuracy of the concrete, making it particularly suitable for pouring deep beams, high columns, and other special locations.

[0050] In some examples, the vehicle body 10 has a set of wheels at the bottom and a horizontal mounting platform at the top. The bottom of the concrete hopper 1 has a positioning protrusion adapted to the mounting platform of the vehicle body 10, and a corresponding positioning groove is formed on the mounting platform of the vehicle body 10. The two are positioned horizontally using a mortise and tenon joint. A retaining plate is provided on the outer wall of the concrete hopper 1, and a corresponding slot is provided on the edge of the mounting platform of the vehicle body 10. The retaining plate and slot are fastened together with bolts, allowing for detachable fixing of the concrete hopper 1 to the vehicle body 10. When the pouring device needs to be moved, the concrete hopper 1 is securely mounted on the vehicle body 10 using the above structure. When working in confined spaces, the connecting bolts can be removed, allowing the concrete hopper 1 to be detached from the vehicle body 10 and transported separately to the work area.

[0051] The detachable structure of the vehicle body 10 and the concrete hopper 1 significantly improves the mobility and operational adaptability of the device. The vehicle body 10 is not limited to any particular model; it can be a self-propelled vehicle or a trailer-mounted vehicle. The power for the screw conveyor 9 is provided by the self-propelled vehicle body 10 or by an additional external rotating drive structure. In large-scale construction scenarios, the concrete hopper 1 is mounted on the vehicle body 10 and can be quickly moved to the work location via its wheel set, improving equipment relocation efficiency by more than 100% compared to traditional manual handling. In narrow spaces or stairwells where vehicles cannot pass, the concrete hopper 1 can be removed and transported separately, solving the problem of blind spots caused by the large size of existing mechanized equipment. The detachable design also facilitates equipment maintenance and upkeep. When the interior of the concrete hopper 1 needs cleaning or repair, it can be quickly separated for operation, reducing equipment downtime. Furthermore, the vehicle body 10 provides modular expansion capabilities for the device. Storage tanks, power sources, and other auxiliary equipment can be added to the vehicle body 10 according to construction needs, increasing the integration level of the device.

[0052] In some examples, a mounting frame 11 is provided at the bottom of the concrete hopper 1. The mounting frame 11 is a rectangular frame structure, and its outer wall is detachably connected to the bottom edge of the concrete hopper 1 by bolts. A sealing strip is provided at the connection interface between the two to prevent concrete leakage. The main discharge port 102 is located in the central area of ​​the bottom plate of the mounting frame 11. Vertical guide rails are provided on both inner walls of the mounting frame 11. The sliding stop 2 slides along the guide rails through a slider to achieve lifting and sliding along the height direction of the mounting frame 11. When it is necessary to replace or repair the discharge component, the mounting frame 11 and the sliding stop 2 can be separated from the concrete hopper 1 by removing the connecting bolts for independent operation.

[0053] The detachable design of the mounting frame 11 significantly improves the ease of maintenance and component versatility of the device. When the main discharge port 102 or the sliding stop 2 becomes worn or clogged, the mounting frame 11 can be quickly removed for cleaning or replacement without disassembling the entire concrete hopper 1, thus shortening maintenance time. This structure also supports modular replacement of different specifications of discharge components. By replacing the mounting frame 11 with different sizes of main discharge port 102 or constricted pipe 201, it can quickly adapt to different pouring scenarios.

[0054] In some examples, horizontal hinge shafts are provided on both sides of the top of the vehicle body 10, and the swing frame 12 is rotatably connected to these hinge shafts via bearings, forming a swing pair around a horizontal axis. The swing frame 12 has a U-shaped frame structure, with the middle of its two side arms fixed to the horizontal hinge shafts, and the concrete bucket 1 is fixed to the top platform of the swing frame 12 by bolts. A swing drive mechanism is provided on the vehicle body 10, which includes a hydraulic push rod hinged at both ends, one end of which is hinged to the bottom of the vehicle body 10, and the other end of which is hinged to the bottom arm of the swing frame 12. When the hydraulic push rod extends or retracts, it pushes the swing frame 12 to swing up and down around the horizontal hinge shaft, thereby driving the concrete bucket 1 to simultaneously achieve a tilt angle adjustment of 0-60°.

[0055] The swing design of the swing frame 12 around a horizontal hinge axis enables the concrete hopper 1 to have a pitch adjustment function, effectively solving the problem of fixed discharge angle in traditional devices. Driven by a hydraulic pusher, the concrete hopper 1 tilts up and down, precisely adjusting the orientation of the main discharge port 102, allowing concrete to flow by gravity along the inclined direction to the target pouring position. This is particularly suitable for non-vertical pouring scenarios such as window sills and sloping walls. The horizontal hinge axis ensures that the center of gravity of the concrete hopper 1 remains stable during the swing, avoiding the risk of equipment tipping over due to excessive tilting and improving safety during high-altitude operations or slope construction. This structure eliminates the need for manual lifting of the concrete hopper to adjust the angle, achieving precise control of the discharge direction through mechanical drive, shortening the pouring time for complex sections, and reducing the physical exertion of operators.
