Description

Technical Field

[0001] This application relates to the field of concrete mixing technology, and more particularly to a mobile forced concrete mixing device. Background Technology

[0002] Forced mixers are a common type of equipment in the construction industry. They consist of a mixing drum and rotating mixing blades installed inside the drum. The mixing blades are connected to a mixing motor via a mixing shaft, which drives the mixing motor to rotate the mixing blades at high speed. This causes the materials to be sheared, squeezed, tumbled, and convectioned, resulting in more intense, uniform, and efficient mixing.

[0003] Existing forced mixers operate in two modes: continuous mixing and intermittent mixing. The advantage of intermittent mixing is that it can precisely control the proportions of water, mortar raw materials, and aggregates, ensuring that the mixed concrete has good molding quality. In the specific construction process, water of a pre-mixed ratio is injected into the mixing drum through a water injection pipe. Then, a hopper containing mortar raw materials of a pre-mixed ratio is installed at the inlet of the mixing drum. The mortar raw materials are added to the water through the inlet and mixed to form cement mortar. Finally, a hopper containing aggregates and other materials of a pre-mixed ratio is installed at the inlet of the mixing drum. The aggregates and other materials are added to the cement mortar through the inlet and mixed to obtain the desired concrete paste.

[0004] For outdoor road construction and other similar work scenarios, forced mixers can be installed on mobile flatbed trucks or other movable carriers, allowing for easy repositioning of the mixer. However, during concrete mixing, the silos containing mortar raw materials and aggregate silos need to be hoisted sequentially to the top inlet of the mixing drum using lifting equipment and connected accordingly before the materials can be added to the inside of the mixing drum for thorough mixing. The overall process is cumbersome, time-consuming, and labor-intensive, and needs improvement. Summary of the Invention

[0005] Based on this, this application provides a mobile forced concrete mixing device that can place mortar raw materials and aggregates in the same silo according to the mixing ratio. After the subsequent silo is installed after the mixing drum, the mortar raw materials and aggregates can be fed in sequence, simplifying the operation process and improving the overall efficiency of concrete mixing.

[0006] The mobile forced concrete mixing device provided in this application adopts the following technical solution: A mobile forced concrete mixing device, comprising: Hanger assembly; The mixer body is fixed to the hanger assembly; the mixer body includes a mixing drum and a cover covering the top of the mixing drum, the cover having a feed inlet and a first control mechanism for controlling the opening and closing of the feed inlet; The hopper is detachably mounted on top of the cover. A plug-in structure is provided between the hopper and the cover to achieve alignment and plug-in between the hopper and the cover. The hopper contains a mechanism chamber, a first storage chamber, and a second storage chamber arranged sequentially from bottom to top. The bottom of the mechanism chamber is provided with a docking interface for connecting with the feed inlet. The bottom of the first storage chamber is provided with a discharge port and a second control mechanism for controlling the opening and closing of the discharge port. The bottom of the second storage chamber is provided with a discharge port and a third control mechanism for controlling the opening and closing of the discharge port.

[0007] By adopting the above technical solution, this application sets up a first storage chamber and a second storage chamber inside the silo. The first storage chamber is used to store mortar raw materials, and the second storage chamber is used to store sand, gravel, and auxiliary materials, thus enabling the materials to be mixed to be stored together in one silo. In specific operations, an appropriate amount of water is first injected into the mixing drum. Then, the silo is lifted using hoisting equipment, and the inlet of the silo is aligned with the inlet of the cover. By controlling the first control mechanism to open the inlet and the second control mechanism to open the outlet, the mortar raw materials inside the first storage chamber gradually enter the mixing drum and are mixed with water to form cement mortar. After initial mixing, the third control mechanism is then controlled to open the outlet, allowing the sand, gravel, and auxiliary materials inside the second storage chamber to gradually enter the mixing drum and be mixed with the materials, thereby producing concrete slurry. The entire operation process is efficient and convenient, requiring no secondary hoisting operations, and improving the overall efficiency of concrete mixing.

[0008] Optionally, the first control mechanism includes two first flaps, which together block the feed inlet in the initial state. Each of the two opposite sides of the first flaps is fixed with a connecting shaft, and each connecting shaft is rotatably connected to a movable support column at its end away from the first flap. Each movable support column is vertically slidably mounted on the inner top wall of the cover. A first spring is provided between each connecting shaft and the movable support column, and the first spring is used to force the connecting shaft to reset and rotate, keeping the two first flaps horizontally facing each other. The top surface of the first flap is provided with a limiting groove, and the inner top wall of the cover is provided with a limiting protrusion protruding downward; each movable support is provided with a magnetic attraction component between it and the cover. The magnetic attraction component is used to force the movable support to rest against the inner top wall of the cover in a normal state. At this time, the limiting protrusion is matched and inserted into the limiting groove. The first control mechanism also includes a rotating shaft rotatably disposed inside the cover and a rotary motor for driving the rotating shaft to rotate. A drive gear is fixedly sleeved on the outside of the rotating shaft, and a driven gear is fixedly sleeved on the outside of the connecting shaft. When the hopper is aligned and inserted into the cover, the insertion structure can force each movable support to move downward. At this time, the limiting protrusion disengages from the limiting groove, and the driven gear can mesh with the drive gear for transmission.

[0009] By adopting the above technical solution, the first flap of this application is rotatably connected to the movable support column via a connecting shaft. The first spring enables the two first flaps to reset and rotate to maintain a horizontal alignment. Under the magnetic attraction of the magnetic component, the movable support column can normally abut against the inner top wall of the cover. At this time, the limiting groove of the first flap can match and insert with the limiting protrusion of the cover, thereby restricting the rotation of the first flap and enabling the two first flaps to jointly cover the feed inlet, thus playing a dustproof role.

[0010] Due to the limited space inside the mixing drum, if the first flap tilts downwards, it may interfere with or collide with the mixing shaft inside the drum. Therefore, this application addresses this issue by vertically sliding the movable support column onto the cover. After the hopper is hoisted and connected to the cover, the plug-in structure forces the movable support column, connecting shaft, and first flap to move downwards together. This allows the limiting groove of the first flap to disengage smoothly from the limiting protrusion, releasing the limiting lock on the first flap. At this time, the driven gear on the connecting shaft meshes with the driving gear on the lower rotating shaft, and by controlling the rotation of the rotary motor, the first flap can be rotated upwards, thus smoothly opening the feed inlet.

[0011] Optionally, the plug-in structure includes multiple plug-in posts fixedly installed at the bottom of the hopper and multiple plug-in slots extending through the top surface of the cover. The number of plug-in slots matches the number of movable support columns, and each plug-in slot is directly opposite to each movable support column. The plug-in posts and plug-in slots are plugged into each other. In the working state, the plug-in posts can pass through the plug-in slots, abut against the movable support columns, and force the movable support columns to move downward.

[0012] By adopting the above technical solution, after the hopper is hoisted to the top of the cover by the hoisting equipment, the docking interface of the hopper is connected to the feed inlet of the cover, and each plug-in post is inserted into the corresponding plug-in slot. Each plug-in post can abut against the corresponding movable support, so that each movable support, each connecting shaft and the two first flaps move downward together, which can smoothly release the limit lock of the first flaps, so that the first flaps can cooperate with the rotating shaft for transmission.

[0013] Optionally, the second control mechanism includes two second flaps rotatably mounted on the discharge port and a support unit for controlling the rotation of the two second flaps respectively; wherein, the support unit includes a support plate frame slidably mounted on the top wall of the mechanism chamber and a swing rod rotatably mounted on the support plate frame, a frame plate is fixed on the bottom surface of the second flap, the frame plate is provided with a sliding waist hole, and the end of the swing rod away from the support plate frame is slidably mounted in the sliding waist hole; A second spring is provided between the support plate frame and the hopper. In the initial state, the second spring is used to force the two support plates frame to approach each other normally, at which time the support plates frame abuts against the bottom surface of the second flap. In the working state, the first flap rotates under the drive of the rotary motor, which can abut against the support plate frame and force the two support plates frame to move away from each other. The swing lever can force the second flap to rotate downward to open the discharge port.

[0014] By adopting the above technical solution, the support plate frame of this application is normally located below the second flap under the elastic force of the second spring, which can provide stable support for the corresponding second flap, thereby allowing the two second flaps to jointly block the discharge port. After the hopper is connected to the feed port of the cover, the first flap is rotated upward by controlling the operation of the rotary motor. During the rotation of the first flap, it can gradually abut against the support plate frame and force the support plate frame to move horizontally, so that the support plate frame is away from directly below the second flap, thereby releasing the limiting support on the second flap. After the support plate frame is away from below the second flap, the swing rod finally abuts against one side end wall of the sliding waist hole. As the support plate frame continues to move, the swing rod can pull the second flap to gradually rotate downward, thereby opening the discharge port so that the mortar raw material inside the second storage chamber can smoothly enter the mixing drum through the discharge port.

[0015] Optionally, the support unit also includes a side plate frame that is slidably disposed on the outside of the hopper and a threaded rod that is rotatably connected to the side of the hopper. The threaded rod passes through the side plate frame and is threadedly connected to the side plate frame. A hollow sleeve is provided on the side of the side plate frame near the hopper. The hollow sleeve is movably disposed through the side wall of the mechanism chamber. The support plate frame has a movable insert on the side away from the hopper, which is movably inserted into the hollow sleeve; a second spring is set between the movable insert and the hollow sleeve to force the movable insert to move normally away from the inner end wall of the hollow sleeve.

[0016] By adopting the above technical solution, this application controls the operation of the rotary motor and opens the feed inlet simultaneously. Through the cooperation of the first flap and the support plate frame, the discharge port can be opened synchronously. In this state, the opening range of the discharge port is small, which is conducive to the slow addition of mortar raw materials into the mixing drum for mixing, avoiding the situation where the material solidifies and seizes up due to the addition of a large amount of material at one time. Afterwards, the construction personnel manually rotate the threaded rod with the help of auxiliary tools, or use an external drive component to drive the threaded rod to rotate. The threaded engagement between the threaded rod and the side plate frame allows the side plate frame to gradually move away from the hopper, which in turn can further pull the support plate frame to move away from the discharge port. During this process, the support plate frame forces the second flap to rotate through the swing rod, which can further open the discharge port to facilitate the rapid feeding and mixing of mortar raw materials.

[0017] Optionally, the third control mechanism includes a third flap that is rotatably installed at the discharge port and a control unit for controlling the rotation of the third flap; wherein, the control unit includes a lifting plate seat that is vertically slidably installed on the inner wall of the mechanism, a push plate seat that is horizontally slidably installed on the inner wall of the mechanism, and a linkage rod that is hinged between the lifting plate seat and the push plate seat, and the linkage rod is always inclined. A third spring is provided between the lifting plate seat and the bottom wall of the mechanism chamber. In the initial state, the third spring is used to force the lifting plate seat to move upward normally. At this time, the push plate seat moves laterally to the extreme position away from the lifting plate seat. The outer fixed frame of the hollow insert is equipped with a push rod. The push rod is located on the moving path of the push plate seat along the moving direction of the hollow insert. When the side plate frame moves outward, the push rod can abut against the push plate seat and force the push plate seat to move horizontally. Several vertical sliding rods are fixed to the top of the lifting plate seat. The vertical sliding rods pass through the inside of the first storage chamber, and a pull rod is rotatably installed at the top of the vertical sliding rod. The end of the pull rod away from the vertical sliding rod is rotatably connected to the third flap. In the initial state, the pull rod can force the third flap to normally block the discharge port.

[0018] By adopting the above technical solution, the lifting plate seat of this application can move upward to the limit position under the elastic force of the third spring. At this time, the push plate seat can be in the limit position away from the lifting plate seat under the push of the linkage rod. When the construction personnel force the side plate frame to move away from the silo, the hollow sleeve moves with the side plate frame. During the movement, the push rod component mounted on the hollow sleeve can abut against the push plate seat and drive the push plate seat to move inward. During the movement of the push plate seat, the lifting plate seat can be forced to move downward through the linkage rod, thereby driving the vertical slide rod to move downward. Based on this, after the vertical slide rod moves vertically, the third flip plate can be driven to flip downward through the pull rod component, thereby smoothly opening the discharge port. This allows the sand and gravel auxiliary materials in the second storage chamber to enter the first storage chamber through the discharge port and be added to the mixing drum through the discharge port at the bottom of the first storage chamber, and fully mixed to obtain concrete slurry.

[0019] Optionally, multiple vertical slide bars are provided, and multiple baffle bars are fixed between adjacent vertical slide bars. The baffle bars are arranged at equal intervals along the vertical direction, and all the baffle bars together form a screen structure for intercepting large volumes of sand and gravel auxiliary materials.

[0020] By adopting the above technical solution, when the vertical slide bar moves downward and drives the third flap to rotate to open the discharge port, the screen structure formed by the multiple baffle bars can intercept large-volume sand and gravel auxiliary materials, reducing the occurrence of large-volume sand and gravel auxiliary materials falling into the mixing drum and causing the mixing motor of the mixing mechanism to seize or malfunction, which is conducive to the normal operation of the mixing operation.

[0021] Optionally, a loading port is provided between the second storage chamber and the first storage chamber, and the loading port and the unloading port are staggered; an isolation cover plate is detachably installed on the inner side of the second storage chamber, and in the operation state, the isolation cover plate is matched and covered on the loading port.

[0022] By adopting the above technical solution, after the mixing operation is completed, the silo is lifted by hoisting equipment to detach it from the mixing drum. After removing the large volume of sand and gravel materials trapped inside the silo, the construction personnel force the side plate frame to return to its initial position, which allows the discharge port and the feed port to be closed again. At this time, the construction personnel can remove the isolation cover from the second storage chamber by hoisting, and new mortar raw materials can be loaded into the first storage chamber through the loading port. Then, the isolation cover is reinstalled in the second storage chamber to cover the loading port, and new sand and gravel materials can be loaded into the second storage chamber to facilitate the smooth progress of the next mixing operation.

[0023] Optionally, the hanger assembly includes a base frame and a structural box fixed to the base frame. The top of the structural box is equipped with a hook for lifting with hoisting equipment. The interior of the structural box is divided by partitions to form a water supply room, a power distribution room, and a counterweight room. The counterweight room is used to store various supporting construction tools.

[0024] By adopting the above-mentioned technical solution, the hooks installed on the top of the structural box can be used for hoisting equipment, thereby lifting the entire forced concrete mixing unit and placing it on a vehicle for use, which has the advantages of being mobile and convenient for construction. In addition, the water supply chamber can be used to store water, which can be used to supply water to the mixing drum, or to supply water to the equipped high-pressure cleaning device for vehicle washing and road cleaning; the power supply chamber is equipped with a mobile power supply to power various functional components; the counterweight chamber is used to place construction tools to increase the overall weight of the structural box, thereby balancing the weight of the entire mobile forced concrete mixing unit and ensuring the stability of the equipment.

[0025] Optionally, the base frame is rotatably equipped with multiple sets of guard plate mechanisms; wherein, the guard plate mechanism includes a main guard plate and two side wing plates rotatably connected to the two sides of the main guard plate. In the working state, the main guard plate and the side wing plates of each set of guard plate mechanisms together surround the side of the base frame.

[0026] By adopting the above technical solution, when construction workers are working in windy conditions, they can park the vehicle equipped with the mobile concrete forced mixing device on the windward side, and then unfold the various protective plate mechanisms so that each main protective plate and each side wing plate are placed side by side to block the wind, thereby creating a good working environment for construction workers.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a first storage chamber for storing mortar raw materials and a second storage chamber for storing aggregates inside the silo, the materials that need to be mixed can be stored together in one silo. After the subsequent silo is installed in the mixing drum, the mortar raw materials and aggregates can be fed in sequence, simplifying the operation process and improving the overall efficiency of concrete mixing. 2. The water supply chamber can be used to store water, which can be used to supply water to the mixing drum, or to supply water to the equipped high-pressure cleaning device for vehicle washing and road cleaning; the power supply chamber is equipped with a mobile power supply to power various functional components; the counterweight chamber is used to place construction tools to increase the overall weight of the structural box, and to balance the weight of the entire mobile concrete forced mixing device to ensure the stability of the equipment. 3. By setting up multiple sets of protective plate mechanisms, when construction workers are working in windy conditions, they can park the vehicle equipped with the mobile concrete forced mixing device on the windward side, and then unfold each set of protective plate mechanisms so that each main protective plate and each side wing plate are placed side by side to block the wind, thereby creating a good working environment for construction workers.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 15 This application will be described in further detail. Example 1

[0031] This application discloses a mobile forced concrete mixing device.

[0032] Reference Figure 1 A mobile forced concrete mixing device includes a hanger assembly 1, a mixer body, and a hopper 5. The hanger assembly 1 includes a base frame 11 and a structural box 12. In this embodiment, the base frame 11 is a basic frame constructed of steel sections, which mainly serves as the mounting carrier for the structural box 12 and the mixer body. It can be hoisted onto a large vehicle for transport during use. It should be noted that, according to actual needs, in another feasible embodiment, the base frame 11 can also be equipped with wheels and a driving system for standalone use.

[0033] The structural box 12 is fixed to the top of the base frame 11. Hooks 124 are fixed at the four corners of the top of the structural box 12. The hooks 124 can be hooked by external hoisting equipment to move the hoist assembly 1. The interior of the structural box 12 is divided by partitions to form a water supply chamber 121, an electrical distribution chamber 122 and a counterweight chamber 123. The water supply chamber 121 contains a water storage tank and a high-pressure cleaning system. The water storage tank has a water storage function and can supply water to the mixer body and the high-pressure cleaning system. It can also be equipped with a constant temperature system to maintain the water temperature. The high-pressure cleaning system is a combination of high-pressure pipelines and high-pressure spray guns. It can clean the road surface during construction or wash vehicles after construction to reduce the occurrence of dirt adhesion.

[0034] The power distribution room 122 is equipped with a power supply system to power various electrical systems and components. The counterweight room 123 contains multiple sets of supporting construction tools, which not only facilitate the storage and retrieval of the tools but also balance the overall weight of the mobile forced concrete mixing device, preventing it from tipping over due to weight imbalance. It should be noted that the positions of the water supply room 121, power distribution room 122, and counterweight room 123 in this embodiment can be freely arranged without special restrictions, as long as they effectively balance the overall weight of the device and prevent accidental tipping. Furthermore, depending on actual usage needs, the top of the enclosure 12 can also be equipped with a lighting system and a windproof and rainproof canopy to adapt to various scenarios such as nighttime construction and outdoor construction.

[0035] Reference Figure 2 , Figure 3 The mixer body includes a mixing drum 2 and a cover 3. The mixing drum 2 is fixedly mounted on the base frame 11 and located outside the structural housing 12. A stirring mechanism 21 is rotatably installed inside the mixing drum 2. The stirring mechanism 21 is driven to rotate by a stirring motor 22, thereby forcibly stirring the materials inside the mixing drum 2 to achieve mixing. It should be noted that the mixing drum 2 and the stirring mechanism 21 are conventional designs in the art and are not the focus of this case protection, so they will not be described in detail here.

[0036] Reference Figure 3 The top of the mixing drum 2 is open, and the cover 3 is fixedly installed on the top of the mixing drum 2. The top surface of the cover 3 is provided with a feed inlet 31 that communicates with the inside of the mixing drum 2, and the cover 3 is also provided with a first control mechanism 4 for controlling the opening and closing of the feed inlet 31. In this embodiment, the first control mechanism 4 includes a baffle plate rotatably installed on the side edge of the feed inlet 31. The baffle plate is driven by a motor to achieve opening and closing. Its specific structure is a conventional design in the art and will not be described in detail here.

[0037] Reference Figure 2 , Figure 3The hopper 5 is detachably mounted on top of the cover 3. In this embodiment, multiple hoppers 5 can be equipped, which is beneficial for the continuous mixing operation. After the hopper 5 is fixed on top of the cover 3, it can be supported by other support structures (not shown in the figure). The support structure is a conventional design in the field and is not the focus of this case. It will not be elaborated here.

[0038] The hopper 5 is internally divided into a mechanism chamber 51, a first storage chamber 52, and a second storage chamber 53, arranged sequentially from bottom to top. The mechanism chamber 51 has a docking interface 511 at its bottom, allowing the hopper 5 to connect with the inlet 31 of the cover 3 for material delivery into the mixing drum 2. The first storage chamber 52 has a discharge port 521 at its bottom and a second control mechanism 6 for controlling the opening and closing of the discharge port 521. The second storage chamber 53 has a discharge port 531 at its bottom and a third control mechanism 7 for controlling the opening and closing of the discharge port 531. It is understood that the specific structures of the second control mechanism 6 and the third control mechanism 7 are conventional designs in the field and will not be elaborated further here; their sole purpose is to enable independent opening and closing of the discharge port 521 and the discharge port 531.

[0039] Reference Figure 4 A plug-in structure is provided between the hopper 5 and the cover 3 to achieve alignment and plug-in connection between the hopper 5 and the cover 3. Specifically, the plug-in structure includes plug-in posts 54 and plug-in slots 32 that are adapted to plug in. There are four plug-in posts 54, each of which is fixed to the bottom of the hopper 5, and all plug-in posts 54 are located on the outer periphery of the interface 511. The number of plug-in slots 32 is equal to the number of plug-in posts 54. Each plug-in slot 32 is provided through the top surface of the cover 3. When the interface 511 is aligned with the feed inlet 31, each plug-in slot 32 can be directly aligned with each plug-in post 54, so that the plug-in post 54 can be smoothly inserted into the plug-in slot 32 to limit the lateral movement of the hopper 5.

[0040] Reference Figure 3 , Figure 4In the specific operation, an appropriate amount of water is first injected into the mixing drum 2. Then, the hoisting equipment is used to lift the hopper 5 so that the interface 511 is connected to the feed inlet 31 of the cover 3. By controlling the first control mechanism 4 to open the feed inlet 31 and the second control mechanism 6 to open the discharge port 521, the mortar raw materials inside the first storage chamber 52 can gradually enter the mixing drum 2 and be mixed with water to form cement mortar. After the initial mixing, the third control mechanism 7 is controlled to open the discharge port 531 so that the sand and gravel auxiliary materials inside the second storage chamber 53 can gradually enter the mixing drum 2 and be mixed with the materials to obtain concrete slurry. The whole operation process is relatively convenient, without the need for secondary hoisting operations, which can improve the overall operation efficiency of concrete mixing.

[0041] Back Figure 1 Multiple sets of guard plate mechanisms 8 are rotatably provided on both sides of the base frame 11 in the width direction; wherein, referring to Figure 5 The protective plate mechanism 8 includes a main protective plate 81 and side wing plates 82. The main protective plate 81 is slidably mounted and rotatably installed on the base frame 11. There are two side wing plates 82, which are rotatably connected to the two sides of the main protective plate 81. In the initial state, the main protective plate 81 and the two side wing plates 82 can be folded together and stored inside the base frame 11. In the working state, the construction personnel park the device or the vehicle equipped with the device on the windward side, and then unfold the main protective plate 81 and the side wing plates 82 of each set of protective plate mechanisms 8 and abut or insert them into the ground foundation. Each main protective plate 81 and each side wing plate 82 can jointly surround the side of the base frame 11, thereby successfully blocking the wind and creating a good working environment for the construction personnel. Example 2

[0042] This application discloses a mobile forced concrete mixing device.

[0043] Reference Figure 6 , Figure 7 The present application discloses a mobile concrete forced mixing device. The remaining components are the same as those in embodiment 1, and will not be described in detail here. The difference from embodiment 1 is that the first control mechanism 4 in this embodiment includes two first flaps 41. The two opposite sides of the first flaps 41 are respectively fixed with connecting shafts 42. Each connecting shaft 42 is rotatably connected to a movable support column 43 at the end away from the first flaps 41. The inner top wall of the cover 3 is fixedly provided with guide columns 33. Multiple guide columns 33 are provided and are evenly distributed on the outer periphery of the insertion slot 32. The movable support column 43 slides vertically through the guide column 33, so that each movable support column 43 can slide in the vertical direction.

[0044] In addition, a first spring (not shown in the figure) is provided between each connecting shaft 42 and the movable support 43. In this embodiment, the first spring is a torsion spring. One end of the first spring is connected to the end of the connecting shaft 42, and the other end is connected to the movable support 43. Based on this, the setting of the first spring can force the connecting shaft 42 to reset and rotate, so that the two first flaps 41 are normally kept horizontal and facing each other.

[0045] Reference Figure 8 The top surface of the first flap 41 is provided with a limiting groove 411, and the inner top wall of the cover 3 is provided with a limiting rib 34 protruding downwards. The shape of the limiting rib 34 is adapted to the shape of the limiting groove 411, and the two can be inserted into each other; at the same time, refer to Figure 7 Each movable support column 43 is equipped with a magnetic attraction component (not shown in the figure) between itself and the cover 3. The magnetic attraction component is a magnetic conductor fixedly embedded in the top surface of the movable support column 43, and the cover 3 is made of magnetic metal. This allows the movable support column 43 to normally abut against the inner top wall of the cover 3 under the action of magnetic attraction. At this time, the limiting protrusion 34 can be matched and inserted into the limiting groove 411, thereby realizing the limiting and locking of the first flap 41. It can be understood that in the initial state, that is, when the hopper 5 is not installed on the top of the mixing drum 2, the two first flaps 41 can jointly block the feed inlet 31, which can prevent the dust in the mixing drum 2 from escaping to the outside, achieving a good dust prevention effect.

[0046] It should be noted that in this embodiment, the insertion slot 32 extends from the top surface of the cover 3 to the inner side of the cover 3, and the number of movable support columns 43 is equal to the number of insertion slots 32. Each movable support column 43 is positioned opposite to each insertion slot 32. Under the magnetic attraction of the magnetic component, the movable support column 43 normally abuts against the inner top wall of the cover 3. In the working state, after the hopper 5 is installed on the top of the cover 3 and each insertion column 54 is inserted into each insertion slot 32, the insertion column 54 can pass through the insertion slot 32, abut against the movable support column 43, and force the movable support column 43 to move downward, thereby driving the connecting shaft 42 and the first flap 41 to move downward, so that the limiting groove 411 of the first flap 41 can smoothly disengage from the limiting protrusion 34, thereby releasing the limiting lock on the first flap 41.

[0047] Back Figure 6 The first control mechanism 4 also includes a rotating shaft 44 mounted inside the cover 3 and a rotary motor (not shown in the figure) for driving the rotating shaft 44 to rotate. Two rotating shafts 44 are provided, used to drive the two first flaps 41 to rotate respectively. (See also...) Figure 7Two drive gears 441 are fixedly sleeved on the outer side of the rotating shaft 44, while driven gears 421 are fixedly sleeved on the two connecting shafts 42 on both sides of the first flap 41. When the hopper 5 is aligned and inserted into the cover 3, the insertion post 54 forces the first flap 41 to move downward. Each driven gear 421 can mesh with each drive gear 441. Under the drive of the rotary motor, the rotating shaft 44 can rotate, thereby driving the first flap 41 to flip upward around the central axis of the connecting shaft 42, so as to open the feed port 31 smoothly.

[0048] It should be noted that the above structural design enables the first flap 41 to flip upward around the central axis of the connecting shaft 42. After the first flap 41 is flipped, most of it is exposed above the cover 3, making it less likely to interfere with or collide with the stirring mechanism 21 below. In addition, after the two first flaps 41 are flipped, they can also act as inclined guide plates to guide the material downward into the feed inlet 31, which helps to reduce the occurrence of the material accidentally scattering into the external environment when it is fed.

[0049] Reference Figure 9 The second control mechanism 6 includes two second flaps 61 rotatably mounted on the discharge port 521 and a support unit for controlling the rotation of the two second flaps 61 respectively. The second flaps 61 are hinged to the discharge port 521, and the rotational connecting shafts of the two second flaps 61 are in the same direction as the rotational connecting shafts of the two first flaps 41, meaning the flipping direction of the first flaps 41 is the same as the flipping direction of the second flaps 61. It should also be noted that the discharge port 521 has a stepped surface, so that after the second flaps 61 flip upwards to a horizontal position, they reach their limit position and cannot rotate further.

[0050] Reference Figure 10 The support unit includes a support plate frame 62, a swing rod 63, a side plate frame 64, and a threaded rod 65. The side plate frame 64 is located outside the hopper 5. A hollow sleeve 641 is fixed to one side of the side plate frame 64 near the hopper 5. The hollow sleeve 641 is movably inserted through the side wall of the mechanism chamber 51 and partially located inside the mechanism chamber 51, allowing the side plate frame 64 to slide outside the hopper 5. In addition, two limiting stops 642 are protruding from the outer side of the hollow sleeve 641. One limiting stop 642 is located inside the mechanism chamber 51 to limit the extreme position of the side plate frame 64 moving outward; the other limiting stop 642 is located outside the hopper 5 to limit the extreme position of the side plate frame 64 moving inward.

[0051] One end of the threaded rod 65 is rotatably connected to the side wall of the hopper 5. The threaded rod 65 passes through the side plate frame 64 and is threadedly connected to the side plate frame 64. The end of the threaded rod 65 away from the hopper 5 is provided with an integrally formed swivel handle 651. Based on this, the construction personnel can use auxiliary tools to act on the swivel handle 651 or use an external drive component to act on the swivel handle 651 to drive the threaded rod 65 to rotate. The threaded engagement between the threaded rod 65 and the side plate frame 64 can make the side plate frame 64 gradually move away from / closer to the hopper 5. In the initial state, the side plate frame 64 is in the extreme position of inward movement.

[0052] Reference Figure 11 The bottom surface of the second flap 61 is fixed with several frame plates 611. Each frame plate 611 is provided with a sliding waist hole 612. The length direction of the sliding waist hole 612 is the same as the length direction of the frame plate 611. The support plate frame 62 is slidably set on the top wall of the mechanism chamber 51 through the cooperation of the slide rail slider. One end of the swing rod 63 is rotatably connected to the support plate frame 62. The other end of the swing rod 63 has a pull rod part 631. The pull rod part 631 passes through the sliding waist hole 612 of each frame plate 611 and can move freely in the sliding waist hole 612. A movable insert 621 is fixed on the side of the support plate frame 62 away from the hopper 5. The movable insert 621 is movably inserted into the hollow sleeve 641. A second spring 66 is provided between the hollow sleeve 641 and the movable insert 621. One end of the second spring 66 abuts against the inner end wall of the hollow sleeve 641, and the other end of the second spring 66 abuts against the movable insert 621. The second spring 66 can always generate an elastic force acting on the movable insert 621, thereby forcing the movable insert 621 to move away from the inner end wall of the hollow sleeve 641 in the normal state, so that the two support plates 62 are close to each other in the normal state.

[0053] Reference Figure 10 , Figure 11 In the specific operation process, in the initial state, the side plate frame 64 is in the extreme position of inward movement. At this time, the two support plate frames 62 approach each other under the elastic force of the second spring 66. The two support plate frames 62 can jointly abut against the bottom surface of the second flap 61 to support the second flap 61 and keep the unloading port 521 closed. In addition, in this state, the pull rod part 631 of the swing rod 63 can abut against the side end wall of the sliding waist hole 612 away from the hinge, which can also play an auxiliary support role.

[0054] Reference Figures 10-12After the construction workers hoist the hopper 5 to the top of the cover 3, they control the rotary motor to rotate the first flap 41 upwards. During the rotation of the first flap 41, it gradually comes into contact with the support frame 62 and forces the two support frames 62 to move away from each other, thus gradually moving the support frame 62 away from the bottom of the second flap 61. After the support frame 62 moves away from the bottom of the second flap 61, the tie rod 631 comes into contact with the side wall of the sliding waist hole 612 near the hinge. As the support frame 62 continues to move, the swing tie rod 63 pulls the second flap 61 and gradually rotates it downwards, thereby opening the discharge port 521, so that the mortar raw materials inside the first storage chamber 52 can smoothly enter the mixing drum 2 through the discharge port 521.

[0055] Based on this, this application achieves simultaneous opening of the discharge port 521 by controlling the operation of the rotary motor and opening the feed inlet 31. In this state, the opening range of the discharge port 521 is small, which is conducive to slowly adding mortar raw materials into the mixing drum 2 for mixing, avoiding the situation where the material solidifies and seizes up due to the addition of a large amount of material at one time. Afterwards, the construction personnel can control the threaded rod 65 to rotate, thereby driving the side plate frame 64 to move outward, which in turn pulls the support plate frame 62 to move it away from the discharge port 521, thereby further opening the discharge port 521, so as to facilitate the rapid feeding and mixing of mortar raw materials.

[0056] Back Figure 9 In this embodiment, there are two discharge ports 531, which are located on the two sides of the bottom of the second storage chamber 53. Each discharge port 531 is provided with a set of third control mechanisms 7. In this embodiment, the third control mechanism 7 includes a third flap 71 rotatably mounted on the discharge port 531 and a control unit for controlling the rotation of the third flap 71. The third flap 71 is hinged to the discharge port 531 by a hinge, and the rotatable connection between the third flap 71 and the discharge port 531 is located on the side edge of the discharge port 531 near the other discharge port 531.

[0057] Reference Figure 13 The control unit includes a lifting plate seat 72, a push plate seat 73, and a linkage rod 74. The lifting plate seat 72 is vertically slidably mounted on the inner wall of the mechanism chamber 51 via a sliding rail slider. A third spring 77 is provided between the lifting plate seat 72 and the bottom wall of the mechanism chamber 51, forcing the lifting plate seat 72 to move upwards normally. Several vertical sliding rods 75 are fixed to the top of the lifting plate seat 72. In this embodiment, there are two vertical sliding rods 75, spaced apart. Each vertical sliding rod 75 passes through the top wall of the mechanism chamber 51 and extends into the first storage chamber 52, while referring to… Figure 14A pull rod 76 is rotatably provided at the top of the vertical slide rod 75, and the end of the pull rod 76 away from the vertical slide rod 75 is rotatably connected to the third flap 71.

[0058] In the initial state, the top of the vertical slide bar 75 abuts against the third flap 71, and the pull rod 76 also supports the third flap 71, thus securing the third flap 71 firmly against the discharge port 531. When the lifting plate seat 72 moves downward, the vertical slide bar 75 moves downward with the lifting plate seat 72, and the pull rod 76 pulls the third flap 71 downward, thus smoothly opening the discharge port 531, allowing the sand and gravel auxiliary materials inside the second storage chamber 53 to smoothly enter the first storage chamber 52 through the discharge port 531. In addition, multiple baffle rods 751 are fixedly connected between the two vertical slide bars 75. The baffle rods 751 are equidistantly arranged in the vertical direction, and all the baffle rods 751 together form a screen structure 752. The screen structure 752 can be used to intercept large-volume sand and gravel auxiliary materials, reducing the possibility of large-volume sand and gravel auxiliary materials entering the mixing drum 2 and causing the mixing motor 22 to malfunction, which is conducive to the normal operation of the mixing.

[0059] Reference Figure 15 A sliding guide post 512 is fixedly connected to the inner wall of the mechanism chamber 51. The axis of the sliding guide post 512 is in the same direction as the horizontal direction. The push plate seat 73 is slidably inserted into the sliding guide post 512. The linkage rod 74 is set between the push plate seat 73 and the lifting plate seat 72. One end of the linkage rod 74 is hinged to the push plate seat 73 and the other end is hinged to the lifting plate seat 72. In this embodiment, the linkage rod 74 is always inclined. When the lifting plate seat 72 moves upward to the limit position under the elastic force of the third spring 77, the push plate seat 73 can move laterally to the limit position away from the lifting plate seat 72 under the push of the linkage rod 74.

[0060] Reference Figure 13 The hollow sleeve 641 has a limiting stop 642 fixed frame inside the mechanism chamber 51, which is equipped with a push rod 643. The push rod 643 can be located on the moving path of the push plate seat 73 along the moving direction of the hollow sleeve 641. Based on this, referring to Figures 13-15 When the construction personnel control the threaded rod 65 to rotate and force the side plate frame 64 to move away from the silo 5, after the mortar raw material in the first storage chamber 52 has been discharged, the side plate frame 64 is forced to move outward. Finally, the push rod 643 can abut against the push plate seat 73 and force the push plate seat 73 to move horizontally outward. At this time, the linkage rod 74 can drive the lifting plate seat 72 to move downward gradually, and then the pull rod 76 can force the third flap 71 to rotate downward gradually, so as to open the discharge port 531, so that the mortar raw material and sand and gravel auxiliary materials can be discharged in sequence and mixed smoothly to obtain concrete slurry.

[0061] Additionally, returning Figure 9In this embodiment, a loading port 532 is provided between the second storage chamber 53 and the first storage chamber 52. The loading port 532 is staggered with the unloading port 531, specifically, the loading port 532 is located between the two unloading ports 531. An isolation cover plate 9 is detachably installed on the inner side of the second storage chamber 53. The isolation cover plate 9 is placed in the second storage chamber 53 by means of sliding and limiting the movement of the rail and groove. The isolation cover plate 9 can cover the loading port 532 so that the sand and gravel auxiliary materials can be stored normally in the second storage chamber 53.

[0062] Reference Figure 12 After the mixing operation is completed and the silo 5 is removed from the cover 3, the construction personnel remove the large volume of sand and gravel materials intercepted by the screen structure 752, and then control the threaded rod 65 to rotate to force the side plate frame 64 to return to its initial position, so that the discharge port 521 and the discharge port 531 can be closed again. Then, the construction personnel can remove the isolation cover plate 9 from the second storage chamber 53 by hoisting, and new mortar raw materials can be loaded into the first storage chamber 52 through the loading port 532. Then, the isolation cover plate 9 is reinstalled in the second storage chamber 53 to cover the loading port 532, so that new sand and gravel materials can be loaded into the second storage chamber 53 smoothly, so as to facilitate the smooth progress of the next mixing operation.

[0063] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
