[0031] The feeding system of this utility model includes a base, on which a first storage bin and a second storage bin are provided. A weighing component is provided on the first storage bin and / or the second storage bin.

[0032] When concrete mixers and other equipment need to add materials such as concrete admixtures, the operator or the corresponding feeding structure can add materials to the first storage bin (if there is enough material in the first storage bin, no additional material is needed), and start the conveying component to gradually transport the material in the first storage bin to the second storage bin. The material in the second storage bin is added to the concrete mixer and other corresponding equipment through conveying equipment such as conveyor belts. According to the feedback of the weighing component, the operator or the controller connected to the switch component signal can control the opening of the switch component, thereby controlling at least the opening time and opening size of the second discharge port, and thus realizing the control of the discharge amount of the second storage bin, that is, quantitative discharge. This allows the feeding system in this utility model to meet the addition of materials of various dosages.

[0033] Meanwhile, compared with the method of materials directly entering the second storage silo, the first storage silo serves as a buffer silo for the second storage silo, which plays a certain role in dispersing the materials and slowing down the speed at which the materials enter the second storage silo. This reduces the problems caused by the material feeding speed being too fast due to the second storage silo being set up, resulting in the materials violently impacting the weighing components, and the fact that some materials are not weighed by the weighing components, causing the weighing components to deviate.

[0035] In summary, the feeding system of this utility model can not only be moved to the corresponding location according to the working conditions, realizing the integration and mobility of the feeding system, but also realize quantitative feeding. Attached Figure Description

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 7 As shown, this utility model discloses a feeding system, which includes a base (not shown in the figure), a first storage bin 1 and a second storage bin 2 on the base, and a weighing component on the first storage bin 1 and / or the second storage bin 2; a switch component is provided at least at the second discharge port of the first discharge port of the first storage bin 1 and the second discharge port of the second storage bin 2, and the switch component can at least control the opening and closing of the second discharge port; a conveying component 3 is also provided on the base, which is connected to the first discharge port and the second inlet port 24 of the second storage bin 2 respectively, and is used to convey the material in the first storage bin 1 to the second storage bin 2.

[0048] When concrete mixers and other equipment need to add materials such as concrete admixtures, the operator or the corresponding feeding structure can add materials to the first storage bin 1 (if there is enough material in the first storage bin 1, no additional material is needed), and start the conveying component 3 to gradually transport the material in the first storage bin 1 to the second storage bin 2. The material in the second storage bin 2 is added to the concrete mixer and other corresponding equipment through the conveying equipment such as the conveyor belt. According to the feedback of the weighing component, the operator or the controller connected to the switch component signal can control the opening of the switch component, thereby controlling at least the opening time and opening size of the second discharge port, realizing the control of the discharge amount of the second storage bin 2, that is, quantitative discharge. This allows the feeding system in this utility model to meet the addition of materials of various dosages.

[0049] Meanwhile, compared with the method of materials directly entering the second storage bin 2, the first storage bin 1 serves as a buffer bin for the second storage bin 2, which plays a certain role in dispersing the materials and slowing down the speed at which the materials enter the second storage bin 2. This reduces the problems caused by the material feeding speed being too fast due to the second storage bin 2 being set up, resulting in the materials violently impacting the weighing components, and some materials not being weighed by the weighing components, causing the weighing components to deviate.

[0050] Furthermore, since the first storage bin 1, the second storage bin 2, the switch assembly, the conveying assembly 3, and other structures except for the base in the feeding system are all integrated on the base, the feeding system is integrated. The base can be moved to a set location, allowing the feeding system in this invention to be moved to the required location according to user needs and feed materials to the equipment at that location. In summary, the feeding system in this invention not only moves to the corresponding location according to working conditions, achieving integration and mobility of the feeding system, but also achieves quantitative feeding.

[0051] The operator can connect to the conveying component 3 via a signal, and the controller of the conveying component 3 can adjust the conveying speed of the conveying component 3 to further reduce the speed at which material enters the second storage silo 2. This allows the material to gradually enter the second storage silo 2 and be accurately weighed by the weighing component, further improving the accuracy of the output. However, it should be noted that the conveying speed of the conveying component 3 should not be too slow to ensure that the feeding system can meet the feeding needs of the concrete mixing plant. Compared with the second storage silo 2 alone, the first storage silo 1 and the second storage silo 2 can receive more material. Thus, even if the external material supply is interrupted, the material in the first storage silo 1 can still supply the second storage silo 2 for a period of time until the material supply is restored. Moreover, if the working conditions require, the first storage silo 1 and the second storage silo 2 can also store different types of materials respectively, and the proportioning and supply of compound materials can be achieved through the cooperation of the switching component and the weighing component.

[0052] The switch assembly is located at least at the second discharge port of the first discharge port and the second discharge port. This means that the switch assembly has the following two configuration methods: the switch assembly includes a first switch unit located at the first discharge port of the first storage silo 1 and a second switch unit located at the second discharge port of the second storage silo 2, wherein the first switch unit is used to control the opening and closing of the first discharge port and the second switch unit is used to control the opening and closing of the second discharge port; or, the switch assembly includes a third switch unit located at the second discharge port of the second storage silo 2, wherein the third switch unit is used to control the opening and closing of the second discharge port.

[0053] The designated location refers to the location required by the working conditions, i.e., the location where the feeding system of this utility model needs to be used for feeding, such as a construction site or a mixing plant. Specifically, the material can be added to the concrete mixer within the construction site or mixing plant. A pipeline can be installed between the second discharge port of the second storage silo 2 and the concrete mixer or other equipment requiring feeding, and a pump or other material conveying equipment can be installed on the pipeline to transport the material in the second storage silo 2 to the mixer or other equipment requiring feeding. The feeding system of this utility model can be used to add powdered admixtures (powdered admixtures refer to powdered chemical materials added during concrete mixing to improve concrete performance) or other types of materials. The conveying component 3 specifically includes a pipe 26 with an auger 25 inside, or a conveyor belt, or a conveying pipe with a conveying pump, etc., capable of conveying the material in the first storage silo 1 to the second storage silo 2. Figure 5 As shown, when the conveying assembly 3 includes a pipe 26 and an auger 25 disposed in the pipe 26, arranged along the axial direction of the pipe 26, and rotatably connected to the pipe 26, the pipe 26 is provided with a drive member that can drive the auger 25 to rotate. The end of the pipe 26 away from the drive member is connected to the first discharge port, and the end of the pipe 26 near the drive member is connected to the second feed port 24.

[0054] The base can be moved in several ways. For example, the chassis can be mounted on the chassis of a first transport vehicle. When the feeding system needs to be moved to another location, the driver can use the first transport vehicle to move the feeding system to the desired location. Alternatively, the chassis can be mounted on the first transport vehicle but not on the first. Multiple casters that can move on the ground can be installed on the bottom of the chassis, and the chassis can be connected to a second transport vehicle via ropes or other connecting parts. The second transport vehicle can then move the chassis, thereby moving the feeding system to the designated location. Alternatively, the chassis can be mounted on the casters but not connected to the second transport vehicle. A first drive unit can be installed on the casters to rotate, thereby moving the base to the designated location. The first drive unit can be a rotary motor. Alternatively, the casters can be omitted, and tracks can be installed on the bottom of the chassis with drive wheels that mesh with the tracks. An engine or electric motor can drive the drive wheels to rotate, thereby rotating the tracks and moving the feeding system to the designated location. The first and second transport vehicles mentioned above can be the same or different types of vehicles, as long as they can realize the transfer of the chassis and other structures of the feeding system on the chassis.

[0055] Based on operational requirements and cost considerations, the weighing components are installed on the first storage silo 1 and / or the second storage silo 2. This means that from the time the material enters the first storage silo 1 until it is discharged from the second storage silo 2, the material will be weighed at least once by the weighing components, thus ensuring the accuracy of the quantitative discharge of material from the second storage silo 2. The weighing components include several weighing sensors installed on the first storage silo 1. Specifically, multiple weighing sensors can be installed at the first inlet and the first outlet of the first storage silo 1 (for example, multiple weighing sensors can be installed along the circumference of the first inlet and the first outlet), as well as multiple weighing sensors can be installed in the areas of the first inlet and the first outlet of the first storage silo 1.

[0056] Multiple weighing sensors are installed in different areas of the first storage silo 1. This allows the operator or the controller connected to the weighing component to comprehensively judge the amount of material entering the first storage silo 1, the amount of material remaining in the first storage silo 1, and the amount of material discharged from the first storage silo 1 based on the feedback from multiple weighing sensors (the controller refers to a structure that can receive weighing signals from multiple weighing sensors, process multiple weighing signals such as calculating the average or mode, and output the final weighing signal, such as a microcontroller MCU). This reduces the problem of weighing deviation caused by the material entering the first storage silo 1 too quickly, the failure of some weighing sensors, or the fact that weighing sensors are only installed in a localized area and the center of gravity of the first storage silo 1 is set off-center, thus enabling a more comprehensive and accurate judgment of material changes in the first storage silo 1.

[0057] Similarly, the weighing components installed on the second storage silo 2 can be arranged in the same manner as the weighing components on the first storage silo 1. For example, several weighing sensors 4 can be installed on the second inlet 24 and the second outlet, as well as in the area between the second inlet 24 and the second outlet on the second storage silo 2.

[0058] The switch assembly is configured such that an operator, or a controller connected to the switch assembly signal, can control the switch assembly to close the first discharge port and / or the second discharge port. Based on feedback from the weighing assembly, the first discharge port and / or the second discharge port can be closed and opened in a timely manner, thereby accurately controlling the amount of material conveyed from the first storage silo 1 to the second storage silo 2, and / or the amount of material conveyed from the second storage silo 2 to the concrete mixer and other corresponding equipment.

[0059] The first and second switching units can have various configurations. Taking the first switching unit as an example, the first switching unit includes a first valve, such as a solenoid valve, located at the first discharge port for controlling the opening and closing of the first discharge port; or, the first switching unit includes a first cover plate located at the first discharge port, the area of ​​which must be larger than the first discharge port to ensure that the first cover plate can effectively block the first discharge port when it covers it. The first switching unit also includes a second driving member that is drivenly connected to the first cover plate and can drive the first cover plate to move or rotate in a direction away from or towards the first discharge port; for example, one end of the first cover plate is hinged to the first storage bin 1, and the other end is connected to the second driving member. The first cover plate is rotated in the direction away from and towards the first discharge port by the second driving component, thereby achieving the closing and opening of the first discharge port and controlling the opening time of the first discharge port and the effective flow area of ​​the material through the first discharge port. At this time, the second driving component can be a linear drive device such as a hydraulic cylinder or a pneumatic cylinder. Alternatively, the second driving component drives the first cover plate to move in the direction away from and towards the first discharge port. At this time, the second driving component can be a linear drive device such as a hydraulic cylinder or a pneumatic cylinder. In this case, the first cover plate can slide with the first storage bin 1 or not be set on the first storage bin 1, but it is necessary to ensure that the first discharge port is located on the movement trajectory of the first cover plate so that the first cover plate can block the first discharge port.

[0060] The second switching unit can be arranged with reference to the configuration of the first switching unit described above. For example, the second switching unit includes a second valve located at the second discharge port, which can be a solenoid valve; or, the second switching unit includes a second cover plate located at the second discharge port, and a drive device, such as a hydraulic cylinder, that can move the second cover plate towards and away from the second discharge port to realize the opening and closing of the second discharge port. Figure 4 As shown, the third switching unit includes a third valve 5 located at the second discharge port, and a drive structure 15 for controlling the opening and closing of the third valve 5, and then controlling the opening and closing of the second discharge port. In this case, the third valve 5 can be a slide gate valve (also known as a gate valve), and the drive structure 15 can be a cylinder or hydraulic cylinder, etc.

[0061] The first storage silo 1 has a first inlet connected to the first storage silo 1 and used for filling the first storage silo 1 with materials. The feeding system includes a feeding assembly for adding materials into the first inlet. External materials can be transported into the first storage silo 1 through the feeding assembly to replenish the materials in the first storage silo 1 in a timely manner. The feeding assembly can take various forms. For example, the feeding assembly can be a conveyor belt, which can directly pour bagged or canned materials onto the conveyor belt, and the conveyor belt will transport the materials to the first inlet. Alternatively, the feeding assembly can be a pipe connected to the first inlet, and the pipe is equipped with a conveying pump for pumping materials. By pouring materials into the pipe, the conveying pump will transport the materials to the first storage silo 1.

[0062] Alternatively, the feeding assembly may not employ the aforementioned structure. The feeding assembly includes a gripper for grasping and releasing materials, and a drive unit for moving the gripper to the first feed inlet. For example, the feeding assembly can be a robotic arm with multiple degrees of freedom. The end of the robotic arm is equipped with a container for holding materials, such as an open receiving cylinder. In this case, the robotic arm can rotate the receiving cylinder, causing the opening of the receiving cylinder to face upwards and downwards, and can move the receiving cylinder in multiple directions in space, allowing the receiving cylinder to collect materials from an external material storage tank and add materials to the first storage bin 1. In this case, the drive unit is a robotic arm with multiple degrees of freedom, and the gripper is the receiving cylinder. The robotic arm can refer to existing handling robots; the specific structure will not be elaborated further.

[0063] Alternatively, the gripper includes a support 6, on which are provided several cooperating grippers 7 capable of clamping and releasing packaged materials, and rotatably connected to the support 6. The support 6 also has a driver 8 connected to the grippers 7, which drives the grippers 7 to perform the clamping and releasing actions of the gripper. This allows the gripper to smoothly clamp and release packaged materials. Furthermore, a cutting element for tearing the outer packaging of materials is provided at the first inlet. Specifically, the cutting element can be located directly above the first inlet or on the same plane as the first inlet. Thus, when the gripper, holding packaged materials, moves to the cutting element and the outer packaging of the materials comes into contact with it, the outer packaging is torn by the cutting element, and the materials leak out into the first storage bin 1. As the materials continuously flow out of the outer packaging, the driver 8 can control the gripper... The clamping force on the packaging material, i.e., the outer packaging, is gradually increased, thereby reducing the problem of the outer packaging bag entering the first storage bin 1 with the material due to excessive material outflow speed and insufficient clamping force, which would interfere with the feeding and discharging of the first storage bin 1. The support 6 is also equipped with a pusher plate 9 that is arranged to avoid the gripper 7, and a vibrator 20 connected to the pusher plate 9 that can drive the pusher plate 9 to vibrate. When the gripper clamps the packaging material, the outer packaging of the material comes into contact with the pusher plate 9. This allows the pusher plate 9 to maintain continuous contact with the outer packaging because the drive unit gradually increases the clamping force on the packaging material through the gripper after the outer packaging of the packaging material is cut by the cutting part. That is, the vibrator 20 can drive the material inside the outer packaging to vibrate continuously through the pusher plate 9, ensuring that the material inside the outer packaging can enter the first storage bin 1 evenly and avoid material waste.

[0064] Specifically, the driver 8 can be a rotary motor or hydraulic cylinder, or other device that can drive the gripper 7 to perform clamping and opening actions. The cutting component can be a cutter 19 located at the first feed inlet. The cutter 19 can be a fixed cutter or a rotatable cutter 19 driven by a drive device 22 such as a rotary motor. The vibrator 20 can be a drive device 22 such as a cylinder or hydraulic cylinder that can drive the pusher plate 9 to move towards and away from the outer packaging. Thus, when the vibrator 20 drives the packaged material to vibrate through the pusher plate 9, it can be achieved by the vibrator 20 driving the vibrating plate to reciprocate towards and away from the outer packaging. The amplitude of the reciprocating motion of the pusher plate 9 needs to be controlled within a small range to avoid the problem of the pusher plate 9 moving too far and pushing the unfinished packaged material off the gripper. When the material inside the outer packaging is emptied, the vibrator 20 can drive the pusher plate 9 to move towards the outer packaging, thereby pushing the outer packaging off the gripper. This avoids the problem of the outer packaging of the emptied material being attached to the gripper 7 and unable to fall off due to the gripper holding the outer packaging too tightly, so that the gripper can feed the next packaged material. Packaging materials refer to materials that have outer packaging, such as bags or cans.

[0065] The avoidance arrangement between the gripper 7 and the pusher plate 9 means that the functions of the pusher plate 9 and the gripper 7 do not interfere with each other and can be implemented smoothly on their own. The gripper 7 can also have various configurations. For example, the end of the gripper 7 that contacts the outer packaging of the packaged material has sufficient strength to cut through the outer packaging (in this case, the end of the gripper 7 that contacts the outer packaging can be a pointed tip so that the gripper 7 can break through the outer packaging). In this case, before the gripper moves to the first feed inlet, the drive unit needs to control the movement of the gripper 7 so that the gripper 7 clamps the packaged material but does not cut through the outer packaging. After the packaged material moves to the first feed inlet and contacts the cutting element, the drive unit can make the gripper gradually increase the clamping force on the packaged material, and then make the gripper 7 penetrate into the outer packaging, thereby increasing the rate at which the material flows from the outer packaging into the first storage bin 1; or, the end of the gripper 7 that contacts the outer packaging is insufficient to cut through the outer packaging. In this case, the outer packaging is only cut through by the cutting element.

[0066] Furthermore, a filter screen 10 is provided at the first feed inlet. The diameter of the filter screen 10 is larger than the particle size of the material but smaller than the size of the outer packaging. This ensures that even if the outer packaging is torn, only the material will pass through the filter screen 10 and enter the first storage hopper 1. Because of the gripper 7, the filter screen 10 intercepts the material, preventing the outer packaging from entering the first storage hopper 1 and thus preventing a reduction in the discharge rate of the first storage hopper 1. Specifically, the cutting component can be arranged horizontally alongside the filter screen 10. With the volume of the first storage hopper 1 remaining constant, this reduces the vertical space occupied by the first storage hopper 1. Alternatively, the cutting component can be positioned above the filter screen 10, thereby preventing fragments of the outer packaging from entering the first storage hopper 1 through the gap between the cutting component and the first storage hopper 1.

[0067] The base has a feeding area 11 for placing packaged materials and a collection area 12 for placing empty packages containing emptied materials. The feeding area 11 can be simply a blank area on the base; or, as... Figure 1 , Figure 2 As shown, the top of the support 17 is the feeding area 11. Several internally threaded sleeves are installed below the bottom of the support 17, with legs connected to the internal threads of each sleeve. The number of legs corresponds to the number of sleeves. The legs have external threads; to adjust the height of the support 17, simply rotate the legs. Similarly, the collection area 12 can be a blank area on the base, or a support 17 can be installed to hold the outer packaging of the emptied material. The base also has a frame, with a horizontally oriented slide rail 21 on the top (i.e., from the feeding area 11 towards the collection area 12), a sliding plate 23 (or trolley) that slides with the slide rail 21, and a third drive component 13 for driving the sliding plate 23 to move bidirectionally between the feeding area 11 and the collection area 12. A fourth drive component 14 is located at the bottom of the sliding plate 23, connected to a scissor-type telescopic frame 18. A support 6 is connected to the end of the scissor-type telescopic frame 18 furthest from the fourth drive component 14. When the third drive component 13 is connected to the support 17 of the slide plate 23, the third drive component 13 can be a linear drive device such as a cylinder; alternatively, a rack can be arranged on the slide plate 23 along the direction from the feeding area 11 toward the collection area 12. In this case, the third drive component 13 can be a rotary motor connected to a gear that meshes with the rack. Within the stroke of the slide plate 23, the rack can maintain meshing with the gear. Thus, the rotary motor drives the gear to rotate, and the gear drives the rack to move toward or away from the collection area 12. The fourth drive component 14 can be a linear drive device such as a cylinder. Using a linear drive device to extend and retract the scissor telescopic frame 18 is existing technology. The specific connection relationship between the fourth drive component 14 and the scissor telescopic frame 18 will not be described further.

[0068] like Figure 1 , Figure 2 , Figure 3The diagram shows a specific structure under one embodiment of this utility model. In this case, only the second storage bin 2 is equipped with a weighing component, and the second discharge port is equipped with a third switch unit. When the base moves to the corresponding location and receives a feeding signal, the second discharge port is connected to the equipment to be fed through a pumping pipe or conveyor belt, etc. The conveying component 3, switch component, and rotating cutter are activated. After the operator or forklift or other handling machinery places the outer packaging material on the top of the support 17, the third drive component 13 drives the slide plate 23 to move directly above the support 17. The fourth drive unit 14, through the stretching scissor-type telescopic frame 18, causes the gripper 7 to move towards the outer packaging material above the support 17. The driver 8 drives the gripper 7 to clamp the outer packaging material. The fourth drive unit 14 retracts the scissor-type telescopic frame 18, lifting the outer packaging material above the first storage bin 1. Subsequently, the third drive unit 13 drives the slide plate 23 and the outer packaging material to move directly above the first feed inlet. The fourth drive unit 14 stretches the scissor-type telescopic frame 18, causing the outer packaging material to gradually approach the rotating blade at the first feed inlet. Once the rotating blade cuts through the outer packaging material... After packaging, the material gradually falls from the outer packaging into the first storage bin 1. Simultaneously, the driver 8 controls the gripper 7 to gradually tighten, increasing the clamping force on the outer packaging to ensure it does not enter the first storage bin 1. At this time, the conveying component 3 can be an auger 25, which gradually feeds the material from the first storage bin 1 into the second storage bin 2. The controller or operator, based on feedback from the weighing sensor, determines whether the material being conveyed from the second storage bin 2 to the feeding equipment has reached the required value. When the required value is about to be reached, the material is promptly transferred via the third... The unit closes the second discharge port to ensure the accuracy of the amount of material delivered from the second storage bin 2 to the feeding equipment. After all the material inside the outer packaging has fallen into the first storage bin 1, the third drive component 13 moves the slide plate 23 and the outer packaging to the top of the collection area 12. The fourth drive component 14 stretches the scissor-type telescopic frame 18 to place the empty packaging with the emptied material into the collection area 12. Then, the fourth drive component 14 retracts the scissor-type telescopic frame 18 upwards, and the third drive component 13 moves the slide plate 23 toward the feeding area 11 to prepare for the feeding of subsequent packaging materials.

[0069] like Figure 6 , Figure 7As shown, the support 6 has two opposing mounting seats at its bottom. A rotating rod is rotatably connected inside the mounting seat. Two grippers 7 are fixed at both ends of the rotating rod. A crank arm 16 connected to the driver 8 is sleeved on the rotating rod, and the extension directions of the driving rods of the two drivers 8 are opposite. When the two drivers 8 drive the two crank arms 16 to rotate in opposite directions, they in turn drive the two rotating rods and the grippers 7 on both sides to rotate in opposite directions, thereby clamping the material. Conversely, when the two drivers 8 drive their respective crank arms 16 to rotate in opposite directions, the crank arms 16 drive their respective rotating rods and grippers 7 to rotate in opposite directions, thereby releasing the material. The driver 8 can be a linear drive device such as a cylinder or hydraulic cylinder. If the crank arms 16 are not provided, the driver 8 can also be connected to the end of the rotating rod, and the rotating rod can be directly driven to rotate by the driver 8. In this case, the driver 8 can be a rotary drive device such as a rotary motor.

[0070] Both the support 6 and the pusher plate 9 have several perforated holes to reduce the weight of the gripping component and decrease energy consumption. The shape of the perforated holes is not limited; they can be circular, triangular, etc. However, it is important to ensure that the perforated holes do not significantly reduce the strength of the support 6 and the pusher plate 9 to guarantee their smooth operation. Figure 2 As shown, the second storage bin 2 is located on one side of the first storage bin 1 and is adjacent to the first storage bin 1. This makes the first storage bin 1 and the second storage bin 2 more compact and reduces the space occupied by the feeding system.

[0071] Furthermore, the feeding system of this utility model also includes a discharging component, which includes a feeding element disposed in the first storage bin 1 and / or the second storage bin 2 and rotatably connected to the corresponding first storage bin 1 and / or second storage bin 2, and a fifth driving element connected to the feeding element for driving the feeding element to rotate. By driving the feeding element to rotate through the third driving element 13, the accumulation of material in the first storage bin 1 and / or the second storage bin 2 can be reduced, ensuring the smooth flow of material in the first storage bin 1 and / or the second storage bin 2. The feeding element can specifically be a feeding roller, feeding plate, feeding rod, etc., and the fifth driving element can specifically be a rotary drive device such as a rotary motor that can drive the feeding element to rotate.

[0072] And / or, the discharge assembly includes a vibrator 20 located outside the first storage silo 1 and connected to the first storage silo 1. When it is found that the first storage silo 1 or the second storage silo 2 is not discharging or the discharge speed is slow, the vibrator 20 is activated. The vibrator 20 can drive the corresponding storage silos in the first storage silo 1 and the second storage silo 2 to vibrate, reducing the adhesion and accumulation of materials in the first storage silo 1 or the second storage silo 2, and ensuring the accuracy of the discharge quantity. The vibrator 20 may specifically include a vibration motor connected to the first storage silo 1. And / or, the discharge assembly includes a conveying pipe connecting the second discharge port to the equipment to which the material is to be added. The conveying pipe is provided with a number of air inlets spaced apart along the material conveying direction, and a medium source connected to the air inlets for supplying the conveying medium. Under the push of the subsequent material, the material in the second storage bin 2 is gradually pushed out. Alternatively, a stirring shaft driven by a motor can be installed in the second storage bin 2 to accelerate the material discharge speed. After the material in the second storage bin 2 enters the conveying pipe, it is conveyed by the conveying medium to the equipment to which the material is to be added. The spaced air inlets form a throttle flow conveying, that is, a section of conveying medium and a section of material, which effectively reduces wear during the material conveying process. The medium source can specifically be a gas source that can supply inert gas that does not react with the material into the conveying pipe, such as a nitrogen storage tank, and a conveying pump installed at the outlet of the nitrogen storage tank.

[0073] An anti-stick coating is provided on the inner wall of the first storage silo 1 and / or the inner wall of the second storage silo 2. This anti-stick coating reduces the amount of material adhering to the first storage silo 1 and / or the second storage silo 2. Specifically, the anti-stick coating may be a polytetrafluoroethylene (PTFE) coating. Alternatively, the first inlet is higher than the first outlet, and the side inclination angle of the first storage silo 1 is greater than the angle of repose of the material inside the first storage silo 1. This causes the material inside the first storage silo 1 to tend to move towards the first outlet under the influence of its own weight along the wall of the first storage silo 1, thus reducing material accumulation within the first storage silo 1.

[0074] In this invention, the weighing component, the switching component, the conveying component 3, the feeding component, and the discharging component are all connected to a controller. The controller is used to receive external feeding signals and control the weighing component, the switching component, the conveying component 3, the feeding component, and the discharging component to perform corresponding actions, thereby accurately adding the required amount of material to the concrete mixer and other corresponding equipment.
