Description

Technical Field

[0001] This utility model relates to the field of material storage facilities technology, and in particular to a premixed building material storage silo and storage device. Background Technology

[0002] In construction engineering, premixed building materials typically include premixed concrete and premixed mortar, which are an indispensable pre-mixed mixture in construction.

[0003] To ensure project quality, promote technological progress and industrialization in the construction industry, conserve resources and protect the environment, in accordance with the "Regulations on the Administration of Construction Project Quality" and other relevant requirements, all construction sites currently use pre-mixed concrete and pre-mixed mortar for construction (these pre-mixed materials are proportioned and mixed at the mixing plant to form a usable state, and then transported to the usage location by transport vehicles and used within the specified time). At the construction site, after the concrete and mortar used in construction arrive at the site, one method is to put them into the on-site brick masonry material pool, and according to the needs of use, manually use tools such as shovels to shovel them into handcarts, mortar basins, buckets, etc. and transport them to the usage location.

[0004] The above-mentioned method of manually transferring premixed materials from brick-built material pits suffers from high labor intensity. Furthermore, brick-built material pits incur material and labor costs, cannot be reused, and will incur demolition costs and construction debris later. Additionally, premixed materials adhere to the surface of the brick-built material pits during their use and are difficult to clean, leading to waste and increased cleaning costs. For these reasons, some construction sites now use steel plates to construct material pits (storage tanks). One specific implementation method includes a tank body and a support frame. The support frame provides high-level support for the tank body to facilitate bottom or side material receiving. The tank body is typically designed as a cylindrical or rectangular structure. Cylindrical tanks are equipped with scraper devices, while rectangular tanks are equipped with gravity-fed self-draining funnels at the bottom. This method effectively avoids manual shoveling of premixed materials and allows for the reuse of the material pit.

[0005] According to the applicant's search, in the existing publicly available patent documents, the design of storage devices for premixed materials such as ready-mixed concrete and ready-mixed mortar used in construction often employs a discharge port or discharge pipe located at the bottom of the storage device to discharge materials. Specifically, the solution provided in patent document CN208118128U involves a discharge port at the lower end of the mixing drum, a gate valve installed at the discharge port, and a chute provided at the discharge port, allowing for material discharge by adjusting the direction of the chute. The technical solutions for the combination of the inlet and the concrete conveying pump; in the technical solution with the publication (announcement) number CN218114387U, the relevant discharge mechanism includes a discharge port opened at the bottom of the rear side of the insulation box and a valve adapted to the discharge port; in the technical solution with the publication (announcement) number CN209618006U, the relevant discharge mechanism includes a discharge port at the bottom of the storage tank and a discharge pipe; in the technical solution with the publication (announcement) number CN220884454U, the relevant discharge mechanism includes a discharge assembly set on the bottom plate.

[0006] To facilitate the use of ready-mixed materials such as ready-mixed concrete and ready-mixed mortar at construction sites, it is necessary to optimize the relevant material storage devices. Utility Model Content

[0007] In response to the aforementioned problem of optimizing storage devices for premixed materials such as ready-mixed concrete and ready-mixed mortar, this utility model provides a storage silo and storage device for premixed building materials. This solution optimizes the discharge port on the storage silo, which not only facilitates the discharge of premixed materials but also prevents the premixed materials from affecting the construction quality due to excessive storage time.

[0008] To address the aforementioned problems, this utility model provides a premixed building material storage silo and storage device that solves the problems through the following technical points: A premixed building material storage silo includes a silo body, on which a discharge port for discharging materials from the silo body is provided, and also includes a discharge plate located on the side of the silo body. The height of the discharge plate on the silo body is adjustable, and the discharge plate is configured such that: by raising and lowering the discharge plate, a discharge channel is formed that is synchronous with the raising and lowering of the discharge plate and located above the discharge plate, and the discharge channel serves as the discharge port.

[0009] In use, the silo body provides space for storing materials. For construction projects, these materials include, but are not limited to, premixed materials such as ready-mixed concrete and ready-mixed mortar. The discharge port is used to discharge the materials from the silo body. Specifically, ready-mixed materials such as ready-mixed concrete and ready-mixed mortar are transported from the mixing plant to the construction site by dedicated tank trucks. The tank trucks unload the premixed materials and store them in the silo body. When the premixed materials are needed at the construction site, workers use handcarts, mortar basins, or buckets to collect the materials through the discharge port and transport them to the location of use.

[0010] Unlike existing technologies, this solution adopts a different outlet configuration, providing a technical solution with a different outlet configuration from existing material storage silos. This is to adapt to the characteristics of these premixed materials during storage, which involve continuous solidification and deterioration of fluidity. The solution aims to facilitate material discharge from the silo while avoiding the impact of premixed material solidification on construction quality.

[0011] Specifically, in this solution, a discharge channel is formed by setting a discharge plate on the side of the silo body with an adjustable height relative to the silo body. The discharge plate rises and falls synchronously with the discharge plate and is located above the discharge plate. The discharge channel is used as the discharge outlet. This provides a technical solution in which the discharge plate serves as a partial side wall of the silo body. When the discharge plate descends, a gap is formed in the original position of the discharge plate. The position of the gap changes with the position of the discharge plate. This gap serves as the discharge channel and is used as the discharge outlet to discharge the material in the silo body.

[0012] Unlike existing technologies, in this material storage silo, the discharge port is located on the side wall of the silo body, and its position changes with the notch of the discharge plate. This allows for the discharge of materials from the silo body through the discharge port. For premixed materials such as ready-mixed concrete and mortar, which solidify and deteriorate in fluidity during storage, the discharge plate configuration ensures the material discharge position is always at the top layer. When the material cannot flow naturally under gravity due to its fluidity, a pushing mechanism that changes position synchronously with the discharge plate can be used. This mechanism acts only on the upper layer of material, reducing the need for a separate discharge point at the bottom of the silo body. For mixing materials, since this solution only requires pushing the surface of the material, it not only requires less power from the configured pushing mechanism to achieve the same material discharge purpose, but also does not require the use of traditional pushing mechanisms with complex structures and configurations fixed to the bottom of the silo body to achieve light-load pushing. This facilitates cleaning of the silo body after use. For example, a rotating shaft is set in the silo body, and blades are installed on the rotating shaft at the bottom of the silo body. The motor drives the blades to rotate through the rotating shaft to push the material to the discharge port at the bottom of the silo body. Since the blades, rotating shaft, and steel bracket supporting the rotating shaft are located inside the pool, and the blades are generally staggered with push plates to reduce the area of ​​the pushing area, the complex internal structure of this implementation method has problems such as difficulty in cleaning the premixed material and incomplete cleaning.

[0013] In summary, this solution features convenient premixed material discharge and easy cleaning of used storage silos.

[0014] On the other hand, for ready-mixed concrete and mortar, when stored in the silo under conventional open-top conditions, the surface layer of ready-mixed material, especially under high temperature and low humidity environments, undergoes significant deterioration in a short period compared to the inner layer, due to carbonation, moisture evaporation, and bleeding. For example, without surface protection, significant deterioration of the surface layer of ready-mixed material is highly likely to occur within 1 hour, while the inner layer is usually only affected by hydration reactions. With the current use of retarders, the storage time without affecting construction quality is longer, typically greater than 4 hours. The discharge port is configured to be formed by the discharge plate and its height changes synchronously with the position of the discharge plate. When material is taken from the silo body, the height of the discharge port changes with the position of the material surface. That is, by discharging through the discharge port, material can be easily taken from the surface of the current material. In this way, for materials with no top cover in the silo body, the surface of these materials can be discharged through the discharge port during each material taking process, reducing the time that the top material is directly exposed to the environment during the storage process, thereby avoiding the impact of the premixed material on the construction quality due to excessive storage time.

[0015] In one specific embodiment, when the material in the silo body has good flowability, a notch is created on the side of the silo body by lowering the discharge plate. This notch serves as a discharge channel / outlet, and the material is naturally discharged through the notch under gravity, thus achieving material retrieval from the silo body. When the flowability deteriorates due to solidification or other reasons, a pushing mechanism can be used. This pushing mechanism, under the action of a drive device or manual intervention, pushes the material to the discharge outlet position to complete the material discharge. A preferred application is to use a pushing mechanism that is synchronized with the lifting and lowering of the discharge plate. The specific synchronization scheme can be mechanical or electronic. For example, a mechanical mechanism can be used to synchronize the movement of the pushing mechanism and the discharge plate. A sensor is used to detect the position of either the pushing mechanism or the discharge plate. The position detection result serves as the input signal for the processor, which then outputs a position synchronization control signal for the other. The pushing mechanism is preferably a pushing plate, which performs the pushing action under the action of a drive device.

[0016] As a further technical solution for the aforementioned storage silo:

[0017] The discharge plate is slidably connected to the side of the silo body via a track plate set on the side wall of the silo body: the track plate is provided with a track adapted to the discharge plate, and the side of the discharge plate is slidably connected to the track plate via the track.

[0018] Both sides of the feeding plate are equipped with track plates, and both sides of the feeding plate are slidably connected to the track plates on the corresponding sides.

[0019] The above solution provides a technical solution in which the height of the discharge port on the side of the silo body can be linearly adjusted. The bottom position of the discharge port can be adjusted to any position within the sliding range of the discharge plate. Specifically, the track plate slides along the track to form the bottom position located at the upper end of the discharge plate.

[0020] The hopper body is a strip-shaped box structure, and discharge ports are provided at both ends of the hopper body along its length.

[0021] The above scheme provides a specific implementation method for the silo body and the configuration method of the discharge port on the silo body. Specifically, the strip-shaped box structure, while meeting the volume requirements for accommodating the materials of a single tanker truck, has the characteristics of being compatible with the cargo boxes of traditional transport vehicles and facilitating vehicle transportation. Under this concept, in order to achieve wide coverage of materials by the pushing mechanism to improve pushing efficiency, reduce the width of the pushing mechanism to reduce the design requirements of the walking mechanism that drives the pushing mechanism, reduce the rigidity requirements of the pushing mechanism, and enable materials to gather at the ends of the silo body to achieve fixed-point discharge from the silo body, the silo body is configured with discharge ports at both ends in the length direction, that is, each width of the strip-shaped silo body is provided with a discharge port.

[0022] The hopper body is a strip-shaped box structure, and the discharge plate is the side wall on the width side of the hopper body.

[0023] The above solution provides a specific implementation method for the silo body and the configuration method of the discharge port on the silo body. Specifically, the strip-shaped box structure is used to adapt to the shape of the cargo box of traditional transport vehicles. The discharge plate is the side wall on the width side of the silo body. That is, the entire side wall on the width side of the silo body is used as the discharge plate. When used for ready-mixed concrete, the discharge width of the discharge port is large. Pushing the material along the length direction of the silo body can allow the material to be discharged smoothly from the discharge port. This is to avoid coarse aggregates in ready-mixed concrete being stuck between the pushing mechanism and the side wall of the silo body, which would hinder the pushing or increase the pushing process along the width direction of the silo body.

[0024] It also includes a material gathering device installed at the discharge port to collect the material at the discharge port;

[0025] The material gathering device is a material gathering hopper arranged on the outside of the discharge plate. One end of the material gathering hopper is wider and connects to the discharge plate, serving as the material inlet of the material gathering hopper. The other end of the material gathering hopper is narrower and serves as the outlet of the material gathering hopper.

[0026] This solution aims to aggregate materials at a wide discharge port using a material aggregating device, facilitating final material collection. Specifically, the "wider" and "narrower" refer to the width characteristics of the two ends of the aggregating hopper. The wider end connects to the outer side of the discharge plate, serving as the material inlet of the aggregating hopper to receive materials from the discharge port, ensuring that all materials discharged from above the discharge plate fall into the aggregating hopper. The other end of the aggregating hopper is narrower and serves as the outlet. The aggregating hopper is installed with the wider end higher than the narrower end. After the material falls onto the aggregating hopper, it flows under its own weight towards the outlet and converges, where the user can collect the material.

[0027] The material gathering device includes an auxiliary pushing mechanism located inside the silo body and on the side of the discharge port. The auxiliary pushing mechanism is used to push the material located inside the silo body and on the side of the discharge port toward the discharge port.

[0028] The above provides another material gathering device implementation scheme, which is designed for discharge ports that are relatively narrow. Specifically, it can be configured with a plate-shaped auxiliary pushing mechanism. The auxiliary pushing mechanism is used to push the material located inside the silo body and on the side of the discharge port toward the discharge port. In this way, under the dual action of the auxiliary pushing mechanism and the pushing mechanism, the relatively narrow discharge port can still have reliable discharge characteristics. Compared with the material gathering hopper scheme, this implementation method can effectively reduce the surface area of ​​the storage silo where material adheres during the material discharge process by avoiding the use of the material gathering hopper.

[0029] As another option for the material gathering device, the material gathering device is a material gathering plate disposed outside the discharge port. The material gathering plate is a strip structure with a concave middle section in the width direction. The material gathering plate is arranged parallel to the width direction of the discharge port and located below the discharge port. The relative position of the material gathering plate and the discharge port satisfies the following conditions: the material gathering plate receives materials falling from various positions of the discharge port, one end of the material gathering plate is higher than the other end, and the lower end of the material gathering plate serves as the discharge end of the material gathering plate. In this solution, the height of the material gathering plate is lower than the height of the discharge port. Under the action of natural flow and / or the pusher plate mechanism, the material in the hopper falls from the discharge port onto the material gathering plate and gathers in the concave section. Then, it flows from the high end to the low end of the material gathering plate along the groove formed by the concave section. The material user can receive the material from the discharge end. This solution also effectively solves the problem of how to use tools to receive materials at a concentrated position when the discharge port is set to facilitate the pusher mechanism to push the material.

[0030] As another embodiment of the material gathering device, the device includes a spiral conveyor belt positioned outside the discharge port. The spiral conveyor belt is parallel to the width direction of the discharge port and located below it. The relative position of the spiral conveyor belt to the discharge port satisfies the following condition: the spiral conveyor belt receives materials falling from various positions at the discharge port and transports the materials on it to the roller position via rotation. The spiral conveyor belt is stretched through the roller. In this embodiment, the spiral conveyor belt is stretched below the discharge port via the roller. Materials in the hopper fall from the discharge port onto the spiral conveyor belt under the action of natural flow and / or the pusher plate mechanism. Then, these materials move with the spiral conveyor belt. Because the spiral conveyor belt has a reversing characteristic at the roller position, the materials fall from the spiral conveyor belt under the action of gravity after reaching the roller position. The material user can then receive the materials from this position. This embodiment also effectively solves the problem of how to use tools to receive materials at a centralized location when the discharge port has a wide outlet, in order to facilitate the pushing mechanism.

[0031] Each side of the feeding plate is hooked onto the track plate on that side. The hooking is as follows: for each side of the track plate, the feeding plate provides a force to the track plate to prevent the track plate from moving outward to the side of the feeding plate through the hook connection formed between the track and the track plate.

[0032] The above solution provides a specific connection method between the discharge plate and the track plate. Since the discharge plate is a partial side plate of the silo body, it needs to withstand the compressive force from the material. To optimize the deformation resistance of the silo body, the track plate is fixed to the side wall of the silo body, and each side of the discharge plate is hooked onto the track plate on that side. The hooking is as follows: for each side of the track plate, the discharge plate provides a tensile force towards the track plate in the direction of the discharge plate, preventing the track plate from moving outward relative to the discharge plate. In this application, through the hook connection, the discharge plate, by being tensile on both sides, constrains the deformation of the silo body at the discharge port position, allowing the silo body to still form a complete annular tensile structure in the circumferential direction. Therefore, the hook connection between the discharge plate and the track plate reduces the requirements for the silo body's lateral force resistance design.

[0033] In the mating pair formed by the feeding plate and the track plate, one of the feeding plate and the track plate is provided with a track edge with a side edge, and the other is provided with a track groove with a side groove. The hook is provided as follows: the track edge slides into the track groove, and the side edge slides into the side groove.

[0034] The above provides a specific connection method between the feeding plate and the track plate. The mating pair is the mating structure formed by the end of the feeding plate and the track plate. Specifically, the mating relationship between the side edge and the side groove is used to prevent the track edge from sliding out relative to the track groove along the groove depth direction, thereby constraining the track plate at the end position of the feeding plate. For those skilled in the art, a solution with essentially the same implementation method, purpose, and principle can be implemented, such as a track edge with an enlarged portion and a track groove with an enlarged section. The enlarged portion fits into the enlarged section, and the enlarged section constrains the position of the enlarged portion in the groove depth direction of the track groove, still having the function of constraining the relative position of the feeding plate and the track plate. Such a solution should be understood as an equivalent solution to the above side edge and side groove mating solution.

[0035] This solution also relates to a premixed building material storage device, including a device frame and a storage silo supported on the device frame. The storage silo is any of the storage silos described above, and the silo body is supported on the top of the device frame. The storage device includes the storage silo, which is a specific application of the storage silo.

[0036] As a further technical solution for the aforementioned premixed building material storage device:

[0037] The silo body is an open container with an open top, and also includes a pushing mechanism that can be embedded in the silo body to push the material in the silo body to the discharge port.

[0038] In the above scheme, the open upper part of the silo body facilitates the addition of materials to the storage silo, and the pushing mechanism is used to push the materials in the silo body to the discharge port.

[0039] In one specific embodiment, due to the material density and viscosity, the pushing mechanism experiences significant resistance during its pushing motion. Therefore, the traveling mechanism that drives the pushing mechanism to perform the pushing action is configured to include a traveling trolley and a horizontal plate. The pushing mechanism is mounted on the horizontal plate, with traveling trolleys at both ends. Each traveling trolley is equipped with a traveling track, which is fixed to the side of the hopper body or, for example, on a track frame independent of the hopper body. The traveling track includes a support plate and a toothed plate. The top of the support plate has an upward-facing support surface, and the toothed plate is parallel to the support plate and fixed to its side. The traveling trolley is equipped with a mechanism for... The system includes support wheels for vertical support of the trolley and traveling wheels for traction. The trolley is vertically supported on the support surface of the support plate via the support wheels. The trolley's traveling wheels mesh with the toothed plates. The traveling wheels are driven by a motor or other means. The meshing relationship between the traveling wheels and the toothed plates effectively prevents slippage during the process of the traveling mechanism driving the material pushing mechanism. At the same time, compared to setting the toothed plates on the support surface, the toothed plates located on the side of the support plate are less likely to adhere to the precast mixture splashed onto them on site. Therefore, it can effectively prevent concrete and mortar that have hardened on the toothed plates from affecting the traveling performance of the traveling mechanism.

[0040] In some specific embodiments, the position adjustment of the pushing mechanism in the height direction of the hopper body can be achieved by using an electric mechanism, a pneumatic mechanism, or a hydraulic mechanism.

[0041] One implementation method is to install a lifting mechanism on the horizontal plate. When the lifting mechanism is an electric mechanism, a drive motor can be connected to a reducer, which in turn connects to a transmission mechanism. The transmission mechanism meshes with the gears of the transmission rack on the pushing mechanism. The transmission rack is vertically mounted on the pushing mechanism. When the drive motor rotates, the gears on the transmission mechanism rotate clockwise or counterclockwise. These gears mesh with the gears of the transmission rack, causing the transmission rack to rise or fall synchronously. This allows the pushing mechanism to rise and fall synchronously with the transmission rack. A key feature of this implementation is that the height of the pushing mechanism can be higher than the maximum storage height of the hopper body, and the pushing mechanism... The two ends of the feeding mechanism are respectively attached to the opposite sides of the hopper body. When the feeding mechanism descends to the bottom of the hopper body, it can scrape the entire inner surface of the hopper body. In this way, the feeding mechanism has a large area. To ensure its stability on the horizontal plate, multiple parallel and spaced transmission racks are set on one side of the feeding mechanism. Each transmission rack is equipped with a gear located on the transmission mechanism. A back plate is set on the opposite side of the feeding mechanism. The back plate is set in the slot of the horizontal plate. The slot supports the back plate on the side away from the feeding mechanism, so as to use the back plate to stably constrain the feeding mechanism between the slot and the transmission mechanism.

[0042] One implementation method is to set a pneumatic or hydraulic mechanism on the horizontal plate, with the piston rod of the pneumatic or hydraulic mechanism facing downwards. The pushing mechanism is fixed on the piston rod, and the pushing mechanism is driven to produce synchronous lifting and lowering motion by the lifting and lowering of the piston rod. In this implementation method, if the pushing effect on the material at the bottom of the silo body is to be considered, it is only necessary to ensure that the stroke of the piston rod is sufficient to release the pushing mechanism to the bottom position of the silo body. The advantage of this solution is that the height of the pushing mechanism can be set to be small, and the mechanism for adjusting the position of the pushing mechanism in the height direction of the silo body is simple.

[0043] As a specific implementation, regarding the adjustable design of the pushing mechanism in the height direction of the hopper body, when the discharge port of the hopper body is formed by the following discharge plate and the discharge port is located above the discharge plate, the traveling track can be rigidly connected to the discharge plate. That is, when the discharge plate descends, the traveling track descends synchronously, and the pushing mechanism rigidly connected to the traveling trolley also descends synchronously. This method allows the effective discharge height formed by the discharge plate and the effective pushing height of the pushing mechanism to change synchronously and maintain height adaptability. A single set of lifting drive structure can simultaneously realize the position adjustment of the discharge plate and the pushing mechanism, which is beneficial to the simplification of the structure and control of this device.

[0044] In one specific embodiment, the hopper body serves as the mounting base for the pushing mechanism, that is, the walking mechanism is set on the hopper body, and the pushing mechanism has an indirect connection with the hopper body through the walking mechanism. This implementation method is a preferred embodiment, so as to form a complete set of products with simple structure and convenient installation.

[0045] In one specific embodiment, a spring plate is provided on the side and / or bottom surface of the pushing mechanism, and the spring plate serves as a partial pushing plate body of the pushing mechanism.

[0046] The above implementation aims to utilize elastic plates set on the sides and / or bottom of the pushing mechanism, with the spring plates serving as the pushing plates at these locations, to adapt to the deformation of the silo body and maintain a certain contact force between the pushing mechanism and the inner surface of the silo body. Specifically, when the material is premixed concrete, premixed mortar, or other precast mixtures, due to the high density of the precast mixtures, the silo body will undergo certain compression deformation under the static pressure of the precast mixtures. For example, when the silo body is a rectangular box structure, the material inside may cause the sides of the silo body along its length to be squeezed outwards. If the silo body is empty, the pushing mechanism is adapted to the silo body in a manner that spans the width of the silo body, with both ends of the pushing mechanism and the two inner sides of the silo body. When the pre-mixed material is stored in the silo body, the increase in the width of the silo body will cause a leakage gap between the rigid pushing mechanism and the inner side of the silo body. When the pushing mechanism is equipped with an elastic plate on its side, when the silo is empty, the spring plate can be configured to elastically deform under the compression of the inner side of the silo body. In this way, even if the width of the silo increases under the compression of the pre-mixed material, the spring plate can compensate for the deformation of the silo body through elastic deformation, avoiding the material leakage gap between the pushing mechanism and the silo body. At the same time, the ability of the spring plate to recover deformation can be used to maintain the contact force between the edge of the pushing mechanism and the inner wall of the silo body, thereby reducing the amount of material adhering to the inner wall of the silo after pushing.

[0047] This utility model has the following beneficial effects:

[0048] This solution adopts a discharge port setting that differs from existing technologies, providing a technical solution with a different discharge method from existing storage silos. This is to adapt to the characteristics of these premixed materials during storage, which involve continuous solidification and deterioration of fluidity. The goal is to facilitate material discharge from the silo body while avoiding the impact of premixed materials solidification on construction quality. Attached Figure Description

Detailed Implementation

[0060] The present invention will be further described in detail below with reference to the embodiments, but the present invention is not limited to the following embodiments: Example

[0061] like Figures 1 to 10As shown, a premixed building material storage silo includes a silo body 5, on which a discharge port for discharging materials is provided, and a discharge plate 2 located on the side of the silo body 5. The height of the discharge plate 2 on the silo body 5 is adjustable. The discharge plate 2 is configured such that by raising and lowering the discharge plate 2, a discharge channel is formed that rises and falls synchronously with the discharge plate 2 and is located above the discharge plate 2. The discharge channel serves as the discharge port.

[0062] In use, the silo body 5 provides space for storing materials. For construction projects, these materials include, but are not limited to, premixed materials such as ready-mixed concrete and ready-mixed mortar. The discharge port is used to discharge the materials from the silo body 5. Specifically, ready-mixed materials such as ready-mixed concrete and ready-mixed mortar are transported from the mixing plant to the construction site by dedicated tank trucks. The tank trucks unload the premixed materials and store them in the silo body 5. When the premixed materials are needed at the construction site, workers use handcarts, mortar basins, or buckets to collect the materials through the discharge port and transport them to the location of use.

[0063] Unlike existing technologies, this solution adopts a different outlet setting, providing a technical solution with a different outlet form from existing material storage silos. This is to adapt to the characteristics of these premixed materials during storage, which are continuously solidified and have continuously deteriorated fluidity. This achieves the purpose of facilitating material discharge from the silo body 5, while avoiding the impact of premixed materials solidification on construction quality.

[0064] Specifically, in this solution, a discharge channel is formed by setting a discharge plate 2 on the side of the silo body 5 and having an adjustable height relative to the silo body 5. The discharge plate 2 rises and falls synchronously with the discharge plate 2 and is located above the discharge plate 2. The discharge channel is used as the discharge outlet. This provides a technical solution in which the discharge plate 2 serves as a partial side wall of the silo body 5. When the discharge plate 2 descends, a gap is formed in the original position of the discharge plate 2. The position of the gap changes with the position of the discharge plate 2. This gap serves as the discharge channel and is used as the discharge outlet to discharge the material in the silo body 5.

[0065] Unlike existing technologies, in this material storage silo, the discharge port is located on the side wall of the silo body 5, and the position of the discharge port changes with the notch of the discharge plate 2. Thus, when premixed materials such as premixed concrete and premixed mortar are discharged through the discharge port from the silo body 5, these materials exhibit characteristics such as continuous solidification and decreasing fluidity during temporary storage. The above configuration of the discharge plate 2 ensures that the material discharge position in the silo body 5 is always at the top layer of the material. Therefore, when the material cannot flow naturally under gravity to complete the discharge due to its fluidity, a pushing mechanism 11, whose height changes synchronously with the position of the discharge plate 2, can be used to push the material only onto the upper layer. Under this application, compared to the material discharge required at the bottom of the silo body 5, the material discharge from the silo body 5... Bottom-stirred material: Since this solution only requires pushing the surface of the material, it achieves the same material discharge purpose with the low power required by the configured pushing mechanism 11. Furthermore, it avoids the need for a traditional, complex pushing mechanism 11 fixed to the bottom of the silo body 5 to achieve light-load pushing, thus facilitating cleaning of the silo body 5 after use. For example, a rotating shaft can be installed in the silo body 5, with blades mounted on the bottom side. A motor drives the blades through the rotating shaft to move the material to the discharge port at the bottom of the silo body 5. However, since the blades, rotating shaft, and supporting steel brackets are located inside the tank, and the blades are typically staggered with push plates to reduce the transport area, this complex internal structure presents challenges such as difficulty in cleaning the premixed material and incomplete cleaning.

[0066] In summary, this solution features convenient premixed material discharge and easy cleaning of used storage silos.

[0067] On the other hand, for ready-mixed concrete and mortar, when stored in the silo body 5 under conventional open-top conditions, the surface layer of ready-mixed material, due to carbonation, moisture evaporation, and bleeding, especially under high temperature and low humidity environments, can experience significant deterioration in a short period compared to the inner layer, affecting construction quality. For example, without surface protection, significant deterioration of the surface layer of ready-mixed material is highly likely to occur within 1 hour, while the inner layer of ready-mixed material is usually only affected by hydration reactions. Under current conditions using retarders, the storage time without affecting construction quality is longer, typically greater than 4 hours. The discharge port is configured to be formed by the discharge plate 2 and its height changes synchronously with the position of the discharge plate 2. When material is taken from the silo body 5, the height of the discharge port changes with the position of the material surface. That is, by discharging through the discharge port, material can be easily taken from the surface of the current material. In this way, for materials in the silo body 5 that are not covered at the top, the surface of these materials can be discharged through the discharge port during each material taking process, reducing the time that the top layer of material is directly exposed to the environment during the storage process, thereby avoiding the impact of the premixed material on the construction quality due to excessive storage time.

[0068] In one specific embodiment, when the material in the hopper body 5 has good flowability, a gap is created on the side of the hopper body 5 by lowering the discharge plate 2. This gap serves as a discharge channel / outlet, and the material is naturally discharged through the gap under gravity, thus achieving material retrieval from the hopper body 5. When the flowability deteriorates due to solidification or other reasons, a pushing mechanism 11 can be used. The pushing mechanism 11, under the action of a drive device or manual intervention, pushes the material to the outlet position to complete the material discharge. A preferred application is to use a pushing mechanism 11 that rises and falls synchronously with the discharge plate 2. The specific synchronization scheme can be mechanical or electronic. For example, a mechanical mechanism can be used to synchronize the movement of the pushing mechanism 11 and the discharge plate 2. A sensor is used to detect the position of either the pushing mechanism 11 or the discharge plate 2. The position detection result serves as the input signal for the processor, and the processor outputs a position synchronization control signal for the other. The pushing mechanism 11 is preferably a pushing plate, which performs the pushing action under the action of a drive device. Example

[0069] This embodiment is a further refinement of embodiment 1:

[0070] The discharge plate 2 is slidably connected to the side of the hopper body 5 via a track plate 3 set on the side wall of the hopper body 5: the track plate 3 is provided with a track adapted to the discharge plate 2, and the side of the discharge plate 2 is slidably connected to the track plate 3 via the track.

[0071] Both sides of the feeding plate 2 are equipped with track plates 3, and both sides of the feeding plate 2 are slidably connected to the track plates 3 on the corresponding sides.

[0072] The above solution provides a technical solution in which the height of the discharge port on the side of the hopper body 5 can be linearly adjusted. The bottom position of the discharge port can be adjusted to any position within the sliding range of the discharge plate 2. Specifically, the track plate 3 slides along the track to form a bottom position at the upper end of the discharge plate 2. Example

[0073] This embodiment is a further refinement of embodiment 1:

[0074] The hopper body 5 is a strip-shaped box structure, and discharge ports are provided at both ends of the hopper body 5 along its length.

[0075] The above scheme provides a specific implementation method of the silo body 5 and the configuration method of the discharge port on the silo body 5. Specifically, the strip-shaped box structure, while meeting the volume requirements for accommodating the materials of a single tanker truck, has the characteristics of being compatible with the cargo box of traditional transport vehicles and facilitating vehicle transportation. Under this concept, in order to achieve wide coverage of materials by the pushing mechanism 11, improve pushing efficiency, reduce the width of the pushing mechanism 11, reduce the design requirements of the walking mechanism 7 that drives the pushing mechanism 11, reduce the rigidity requirements of the pushing mechanism 11, and enable materials to gather at the end of the silo body 5, so as to achieve fixed-point discharge of the silo body 5, the silo body 5 is configured with discharge ports at both ends in the length direction, that is: discharge ports are provided on each width side wall of the strip-shaped silo body 5. Example

[0076] This embodiment is a further refinement of embodiment 1:

[0077] The hopper body 5 is a strip-shaped box structure, and the material discharge plate 2 is the side wall of the width side of the hopper body 5.

[0078] The above scheme provides a specific implementation method of the silo body 5 and the configuration method of the discharge port on the silo body 5. Specifically, the strip-shaped box structure is used to adapt to the shape of the cargo box of traditional transport vehicles. The discharge plate 2 is the side wall of the width side of the silo body 5. That is, the entire side wall of the width side of the silo body 5 is used as the discharge plate 2. When used for ready-mixed concrete, the discharge width of the discharge port is large. Pushing the material along the length direction of the silo body 5 can result in smooth discharge from the discharge port. This is used to avoid coarse aggregates in ready-mixed concrete being stuck between the pushing mechanism 11 and the side wall of the silo body 5, which would hinder the pushing or increase the pushing process along the width direction of the silo body 5. Example

[0079] This embodiment is a further refinement of embodiment 1:

[0080] It also includes a material gathering device installed at the discharge port to collect the material at the discharge port;

[0081] The material gathering device is a material gathering hopper 1 arranged on the outside of the discharge plate 2. One end of the material gathering hopper 1 is wider and is connected to the discharge plate 2. This end serves as the material inlet of the material gathering hopper 1. The other end of the material gathering hopper 1 is narrower and serves as the outlet of the material gathering hopper 1.

[0082] This solution aims to aggregate materials at a wide discharge port using a material aggregating device, facilitating final material collection. Specifically, the "wider" and "narrower" refer to the width characteristics of the two ends of the aggregating hopper 1. The wider end connects to the outer side of the discharge plate 2, serving as the material inlet of the aggregating hopper 1 to receive materials from the discharge port, ensuring that all materials discharged from above the discharge plate 2 fall into the aggregating hopper 1. The other end of the aggregating hopper 1 is narrower and serves as its outlet. The aggregating hopper 1 is installed with the wider end higher than the narrower end. When materials fall onto the aggregating hopper 1, they flow under their own weight towards the outlet and converge, where the user can collect the materials. Example

[0083] This embodiment is a further refinement of embodiment 1:

[0084] It also includes a material gathering device installed at the discharge port to collect the material at the discharge port;

[0085] The material gathering device includes an auxiliary pushing mechanism 11 located inside the hopper body 5 and on the side of the discharge port. The auxiliary pushing mechanism 11 is used to push the material located inside the hopper body 5 and on the side of the discharge port toward the discharge port.

[0086] The above provides another material gathering device implementation scheme, which is designed for discharge ports that are relatively narrow. Specifically, it is configured to use a plate-shaped auxiliary pushing mechanism 11. The auxiliary pushing mechanism 11 is used to push the material located inside the hopper body 5 and on the side of the discharge port toward the discharge port. In this way, under the dual action of the auxiliary pushing mechanism 11 and the pushing mechanism 11, the relatively narrow discharge port can still have reliable discharge characteristics. Compared with the material gathering hopper 1 scheme, this implementation method can effectively reduce the surface area of ​​the storage hopper where material adheres during the material discharge process by avoiding the use of the material gathering hopper 1.

[0087] Specifically, such as Figure 7 As shown, the discharge port is only located on a portion of the side wall of the hopper 5 and is formed above the discharge plate 2 (the discharge port is formed above the discharge plate 2). In this configuration, the pushing mechanism 11 cannot effectively cover the material on the side of the discharge port. Therefore, in this configuration, the following measures are required: Figure 8The technical solution shown has an auxiliary pushing mechanism. In this solution, the position of the pushing plate in the auxiliary pushing mechanism in the width direction of the hopper 5 is adjusted by the track, and the position of the pushing plate in the height direction of the hopper 5 is adjusted by the lifting device. In this way, when the lifting device adjusts the height of the pushing plate to match the height of the material pushed by the pushing mechanism 11 in the hopper 5, the pushing plate can push the material located in the hopper 5 and located on the side of the discharge port towards the discharge port when it moves along the track towards the discharge port. Example

[0088] This embodiment is a further refinement of embodiment 2:

[0089] Each side of the feeding plate 2 is hooked onto the track plate 3 on that side. The hooking is as follows: for each side of the track plate 3, the feeding plate 2 provides a force to the track plate 3 to prevent the track plate 3 from moving outward to the side of the feeding plate 2 through the hook connection formed between the track and the track plate 3.

[0090] The above solution provides a specific connection method between the discharge plate 2 and the track plate 3. Since the discharge plate 2 is a partial side plate of the silo body 5, it needs to withstand the extrusion pressure from the material. To optimize the deformation resistance of the silo body 5, the track plate 3 is fixed to the side wall of the silo body 5. Each side of the discharge plate 2 is hooked onto the track plate 3 on that side. The hooking is as follows: for each side of the track plate 3 of the discharge plate 2, the discharge plate 2 provides a pulling force to the track plate 3 in the direction of the discharge plate 2 to prevent the track plate 3 from moving outward relative to the side of the discharge plate 2. Under this application, through the hook connection, the discharge plate 2 is constrained by the tension on both sides of the silo body 5 at the discharge port position. The silo body 5 can still form a complete ring-shaped tensile structure in the circumferential direction. Therefore, the hook connection relationship formed by the discharge plate 2 and the track plate 3 can reduce the requirements for the lateral force resistance design of the silo body 5. Example

[0091] This embodiment is a further refinement of embodiment 7:

[0092] On the mating pair formed by the feeding plate 2 and the track plate 3, one of the feeding plate 2 and the track plate 3 is provided with a track edge with a side edge, and the other is provided with a track groove with a side groove. The hook is provided as follows: the track edge slides into the track groove, and the side edge slides into the side groove.

[0093] The above provides a specific connection method between the feeding plate 2 and the track plate 3. The mating pair is the mating structure formed between the end of the feeding plate 2 and the track plate 3. Specifically, the mating relationship between the side edge and the side groove is used to prevent the track edge from sliding out relative to the track groove along the groove depth direction, thereby constraining the track plate 3 at the end position of the feeding plate 2. As those skilled in the art, a solution with basically the same implementation method, purpose, and principle can be implemented, such as having an enlarged part on the track edge and an enlarged section on the track groove, with the enlarged part fitting into the enlarged section. The enlarged section constrains the position of the enlarged part in the groove depth direction on the track groove, still having the function of constraining the relative position of the feeding plate 2 and the track plate 3. Such a solution should be understood as an equivalent solution to the above-mentioned side edge and side groove mating solution. Example

[0094] This embodiment, based on Embodiment 1, provides a premixed building material storage device, including a device frame 13 and a storage silo supported on the device frame 13. The storage silo is the same as that described in Embodiment 1, and the silo body 5 is supported on the top of the device frame 13. The storage device includes the storage silo, which is a specific application of the storage silo.

[0095] Example 10:

[0096] This embodiment is a further refinement of embodiment 9:

[0097] The hopper body 5 is an open container with an open top, and also includes a pushing mechanism 11 that can be embedded in the hopper body 5 to push the material in the hopper body 5 to the discharge port.

[0098] In the above scheme, the open upper part of the hopper body 5 facilitates the addition of materials to the storage hopper, and the pushing mechanism 11 is used to push the materials in the hopper body 5 to the discharge port.

[0099] In one specific implementation, due to the material density and viscosity, the pushing mechanism 11 experiences significant resistance during its pushing motion. Therefore, the traveling mechanism 7, which drives the pushing mechanism 11 to perform the pushing action, is configured to include a traveling trolley and a horizontal plate 8. The pushing mechanism 11 is mounted on the horizontal plate 8, with traveling trolleys at both ends of the horizontal plate 8. Each traveling trolley is equipped with a traveling track, which is fixed to the side of the hopper body 5 or, for example, to a track frame independent of the hopper body 5. The traveling track includes a support plate 4 and a toothed plate 6. The top of the support plate 4 has an upward-facing support surface, and the toothed plate 6 is parallel to the support plate 4 and fixed to its side. The traveling trolley is equipped with... The trolley is equipped with support wheels for vertical support and traveling wheels for traction. The trolley is vertically supported on the support surface of the support plate 4 via the support wheels. The trolley is driven by a motor or other means through toothed engagement with the toothed plate 6. The toothed engagement between the traveling wheels and the toothed plate 6 can effectively prevent slippage during the process of the traveling mechanism 7 driving the pushing mechanism 11. At the same time, compared with the toothed plate 6 on the support surface, the toothed plate 6 located on the side of the support plate 4 is less likely to adhere to the precast mixture splashed onto it on site. Therefore, it can effectively prevent the walking performance of the traveling mechanism 7 from being affected by the solidified concrete and mortar on the toothed plate 6.

[0100] In one specific implementation, the position of the control walking mechanism 7 on the walking track is configured such that both ends of the support plate 4 are provided with stop devices 14. The stop devices 14 are used to limit the walking range of the walking trolley on the walking track. In one specific implementation, the stop devices 14 are configured to allow the walking trolley to drive the pushing mechanism 11 to the discharge position of the hopper body 5. When the walking trolley reaches the end position of the reciprocating motion, it is still stably constrained on the walking track.

[0101] In one specific implementation, the position adjustment of the pushing mechanism 11 in the height direction of the hopper body 5 can be achieved by using an electric mechanism, a pneumatic mechanism, or a hydraulic mechanism.

[0102] One implementation method is to set a lifting mechanism 9 on the horizontal plate 8. When the lifting mechanism 9 is an electric mechanism, a drive motor can be connected to a reducer, and the reducer can be connected to a transmission mechanism 10. The transmission mechanism 10 meshes with the transmission rack plate 16 on the pushing mechanism 11. The transmission rack plate 16 is vertically arranged on the pushing mechanism 11. When the drive motor rotates, the gear on the transmission mechanism 10 rotates forward or backward. This gear, through meshing with the gear on the transmission rack plate 16, pushes the transmission rack plate 16 up or down, thereby making the pushing mechanism 11 rise and fall synchronously with the transmission rack plate 16. The characteristic of this implementation method is that the height of the pushing mechanism 11 can be set higher than the maximum storage height of the hopper body 5, and the pushing mechanism 11... Both ends of 1 are respectively attached to the opposite sides of the hopper body 5. When the pushing mechanism 11 descends to the bottom of the hopper body 5, it can scrape the entire inner surface of the hopper body 5. In this way, the pushing mechanism 11 has a large area. In order to ensure its stability on the horizontal plate 8, multiple parallel and spaced transmission rack plates 16 are set on one side of the pushing mechanism 11. Each transmission rack plate 16 is equipped with a gear located on the transmission mechanism 10. A back plate 12 is set on the opposite side of the pushing mechanism 11. The back plate 12 is set in the slot of the horizontal plate 8. The slot supports the back plate 12 on the side away from the pushing mechanism 11, so as to use the back plate 12 to stably constrain the pushing mechanism 11 between the slot and the transmission mechanism 10.

[0103] One implementation method is to set a pneumatic or hydraulic mechanism on the horizontal plate 8, with the piston rod of the pneumatic or hydraulic mechanism facing downwards, and the pushing mechanism 11 fixed on the piston rod. By raising and lowering the piston rod, the pushing mechanism 11 is driven to produce synchronous raising and lowering movements. In this implementation method, if the pushing effect on the material at the bottom of the hopper body 5 is to be considered, it is only necessary to ensure that the stroke of the piston rod is sufficient to release the pushing mechanism 11 to the bottom position of the hopper body 5. The advantage of this solution is that the height of the pushing mechanism 11 can be set to be relatively small, and the mechanism for adjusting the position of the pushing mechanism 11 in the height direction of the hopper body 5 is simple.

[0104] As a specific implementation, the position of the pushing mechanism 11 in the height direction of the hopper body 5 is adjustable. When the discharge plate 2 is used to form the discharge port of the hopper body 5 and the discharge port is located above the discharge plate 2, the walking track can be rigidly connected to the discharge plate 2. That is, when the discharge plate 2 descends, the walking track descends synchronously, and the pushing mechanism 11 rigidly connected to the walking trolley also descends synchronously. This method allows the effective discharge height formed by the discharge plate 2 and the effective pushing height of the pushing mechanism 11 to change synchronously and maintain height adaptability. The position adjustment of the discharge plate 2 and the pushing mechanism 11 can be realized simultaneously by using a single set of lifting drive structure, which is beneficial to the simplification of the structure and control of this device.

[0105] In one specific implementation, the hopper body 5 serves as the mounting base for the pushing mechanism 11, that is, the walking mechanism 7 is set on the hopper body 5, and the pushing mechanism 11 has an indirect connection with the hopper body 5 through the walking mechanism 7. This implementation is a preferred embodiment to form a complete set of products with a simple structure and convenient installation.

[0106] In one specific implementation, a spring plate 15 is provided on the side and / or bottom surface of the pushing mechanism 11, and the spring plate 15 serves as a partial pushing plate body of the pushing mechanism 11.

[0107] The above implementation aims to utilize elastic plates set on the sides and / or bottom of the pushing mechanism 11, and to use the spring plate 15 as the pushing plate body at these positions, to adapt to the deformation of the silo body 5 and maintain a certain contact force between the pushing mechanism 11 and the inner surface of the silo body 5. Specifically, when the material is premixed concrete, premixed mortar, or other precast mixtures, due to the high density of the precast mixtures, the static pressure of the precast mixtures will cause the silo body 5 to undergo a certain amount of extrusion deformation. For example, when the silo body 5 is a rectangular box structure, the material inside may cause the sides of the silo body 5 in the length direction to be squeezed outward. If the silo body 5 is empty, the pushing mechanism 11 is adapted to the silo body 5 in a way that spans the width direction of the silo body 5, with both ends of the pushing mechanism 11 contacting the two inner surfaces of the silo body 5. When the pre-mixed material is stored in the silo body 5, the increase in the width of the silo body 5 will cause a leakage gap between the rigid pushing mechanism 11 and the inner side of the silo body 5. When the side of the pushing mechanism 11 is provided with an elastic plate, when the silo is empty, the spring plate 15 can be configured to undergo elastic deformation under the compression of the inner side of the silo body 5. In this way, even if the width of the silo increases under the compression of the pre-mixed material, the spring plate 15 can compensate for the deformation of the silo body 5 through elastic deformation, avoiding the material leakage gap between the pushing mechanism 11 and the silo body 5. At the same time, the ability of the spring plate 15 to recover deformation can be used to maintain the contact force between the edge of the pushing mechanism 11 and the inner wall of the silo body 5, thereby reducing the amount of material adhering to the inner wall of the silo after pushing.

[0110] It also includes a material gathering device installed at the discharge port to collect the material at the discharge port;

[0111] above Figure 9A technical solution with other material gathering devices is provided. Specifically, the strip structure 18 located outside the discharge port of the hopper 5 is the material gathering plate or spiral conveyor belt. In specific implementation, to avoid material waste caused by the material flowing along the outer wall of the discharge plate 2, or to avoid material waste caused by the material falling into the gap between the strip structure 18 and the hopper 5, in this embodiment, a guide plate 17 is fixed to the upper end of the outer wall of the discharge plate 2. After the material falls from the discharge port, the material close to the outer wall of the discharge plate 2 falls onto the guide plate 17, and further falls into the strip structure 18 under the guidance of the guide plate 17. The specific principle diagram is as follows. Figure 10 As stated above.
