[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] As Figures 1 to 7 shown, the present invention discloses a feeding system. The feeding system includes a base (not shown in the figure). A first storage bin 1 and a second storage bin 2 are provided on the base. A weighing assembly is provided on the first storage bin 1 and / or the second storage bin 2; the switch assembly is at least provided at the second discharge port among the first discharge port of the first storage bin 1 and the second discharge port of the second storage bin 2, and the switch assembly can at least control the opening and closing of the second discharge port; a conveying assembly 3 is further provided on the base. The conveying assembly 3 is respectively communicated with the first discharge port and the second feed port 24 of the second storage bin 2, and is used to convey the materials in the first storage bin 1 into the second storage bin 2.

[0048] When adding materials such as concrete admixtures to equipment such as a concrete mixer, an operator or a corresponding feeding structure can add materials to the first storage bin 1 (if there is enough material in the first storage bin 1, there is no need to add materials), and start the conveying assembly 3 to gradually convey the materials in the first storage bin 1 into the second storage bin 2. The materials in the second storage bin 2 are added to corresponding equipment such as a concrete mixer through a feeding device such as a conveyor belt. And according to the feedback of the weighing assembly, the operator or a controller signal-connected to the switch assembly can control the opening of the switch assembly, and then at least control the opening time and opening degree of the second discharge port to realize the control of the discharge amount of the second storage bin 2, that is, quantitative discharge. This enables the feeding system in the present invention to meet the addition of materials in various dosages;

[0049] At the same time, compared with the way that the materials directly enter the second storage bin 2, the first storage bin 1 serves as a buffer bin for the second storage bin 2, plays a certain role in dispersing the materials, slows down the speed of the materials entering the second storage bin 2, and reduces the problem that due to only setting the second storage bin 2, the feeding speed of the materials is too fast, resulting in the materials violently impacting the weighing assembly, and some materials are not weighed by the weighing assembly, causing deviation in the weighing of the weighing assembly;

[0050] Moreover, structures such as the first storage bin 1, the second storage bin 2, the switching assembly, and the conveying assembly 3, etc., except for the base in the feeding system, are integrated on the base, which realizes the integration of the feeding system. And the base can be moved to the set location, which enables the feeding system in the present invention to be moved to the required location according to user needs to feed the equipment at the corresponding location. In summary, the feeding system in the present invention 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 realizes quantitative feeding.

[0051] An operator or a controller that is signal-connected to the conveying assembly 3 and can control the conveying assembly 3 can adjust the conveying rate of the conveying assembly 3 to further reduce the speed of the material entering the second storage bin 2, so that the material can gradually enter the second storage bin 2 and be accurately weighed by the weighing assembly successively, further improving the accuracy of the discharge amount. However, it should be noted that the conveying rate of the conveying assembly 3 should not be too slow to ensure that the feeding system can meet the feeding requirements of the concrete mixing plant. Compared with the separate second storage bin 2, the first storage bin 1 and the second storage bin 2 can receive more materials. In this way, even if the external material supply is interrupted, the material in the first storage bin 1 can still supply the second storage bin 2 for a period of time until the material supply is restored. Moreover, if the working conditions require, the first storage bin 1 and the second storage bin 2 can also store different types of materials respectively, and realize the proportionate supply of composite materials through the cooperation of the switching assembly and the weighing assembly.

[0052] Among them, the switching assembly is at least provided at the second discharge port of the first discharge port and the second discharge port. This means that the switching assembly has the following two setting methods: the switching assembly includes a first switching unit provided at the first discharge port of the first storage bin 1 and a second switching unit provided at the second discharge port of the second storage bin 2. The first switching unit is used to control the opening and closing of the first discharge port, and the second switching unit is used to control the opening and closing of the second discharge port; or, the switching assembly includes a third switching unit provided at the second discharge port of the second storage bin 2, and the third switching unit is used to control the opening and closing of the second discharge port.

[0053] The set location refers to the location required by the working conditions, that is, the location where the feeding system in the present invention is needed for feeding. For example, a construction site or a mixing plant. The material can be specifically added to a concrete mixer in the construction site or the mixing plant. A pipeline can be arranged between the second discharge port of the second storage bin 2 and equipment such as a concrete mixer that needs to be fed, and equipment for conveying materials such as a pump is arranged on the pipeline, so as to convey the materials in the second storage bin 2 into equipment such as a mixer that needs to be fed. The feeding system in the present invention can be used to add powdered admixtures (powdered admixtures refer to powdered chemical materials added during concrete mixing to improve the performance of concrete) or other types of materials. The conveying assembly 3 specifically includes a pipeline 26 provided with an auger 25 inside, or a conveyor belt, or a conveying pipeline provided with a conveying pump and other equipment that can convey the materials in the first storage bin 1 into the second storage bin 2. As Figure 5 shown, when the conveying assembly 3 includes a pipeline 26, and an auger 25 arranged inside the pipeline 26, axially arranged along the pipeline 26 and rotatably connected to the pipeline 26, the pipeline 26 is provided with a driving member that can drive the auger 25 to rotate. One end of the pipeline 26 away from the driving member is communicated with the first discharge port, and one end of the pipeline 26 close to the driving member is communicated with the second feed port 24.

[0054] The movement of the base can be achieved in various ways. For example, the chassis is arranged on the chassis of the first transport vehicle. When the feeding system needs to be moved to other locations, the driver moves the feeding system to the required set location through the first transport vehicle. Or, alternatively, the chassis may not be arranged on the first transport vehicle. A plurality of casters capable of moving on the ground are arranged at the bottom of the chassis, and the chassis and the second transport vehicle are connected together through a connecting member such as a rope. By the advancement of the second transport vehicle, the chassis is driven to move, and then the feeding system is moved to the set location; or, alternatively, the chassis may not be connected to the second transport vehicle. A first driving member capable of driving the casters to rotate and then driving the base to move forward to the set location is arranged on the casters. The first driving member can specifically be a rotary motor. Or, alternatively, the casters may not be arranged. A crawler is arranged at the bottom of the chassis, and a driving wheel meshing with the crawler is arranged. The driving wheel is driven to rotate by an engine or a motor, and then the crawler is driven to roll, and the feeding system is moved to the set location. The above-mentioned first transport vehicle and the second transport vehicle can be of the same or different types, as long as the transfer of the chassis and other structures of the feeding system on the chassis can be realized.

[0055] According to the working condition requirements and cost considerations, the weighing assembly is arranged on the first storage bin 1 and / or the second storage bin 2. This means that during the process from the material entering the first storage bin 1 to the material being discharged from the second storage bin 2, the material can be weighed at least once by the weighing assembly, thus ensuring the accuracy of the quantitative discharge of the material from the second storage bin 2. The weighing assembly includes a plurality of weighing sensors arranged on the first storage bin 1. Specifically, a plurality of weighing sensors can be set at the first feed inlet and the first discharge outlet of the first storage bin 1 (for example, a plurality of weighing sensors are arranged along the circumference of the first feed inlet, and a plurality of weighing sensors are arranged along the circumference of the first discharge outlet), and a plurality of weighing sensors are also arranged in the area of the first storage bin 1 located between the first feed inlet and the first discharge outlet.

[0056] By arranging a plurality of weighing sensors in different areas of the first storage bin 1, the operator or the controller signal-connected to the weighing assembly can comprehensively judge the amount of material entering the first storage bin 1, the amount of material remaining in the first storage bin 1, and the amount of material discharged from the first storage bin 1 based on the feedback of the plurality of weighing sensors (the controller refers to a structure that can receive the weighing signals fed back by the plurality of weighing sensors, and can process the plurality of weighing signals, such as calculating the average or the mode, and output the final weighing signal, such as a microcontroller MCU). This reduces the problem of weighing deviation of the weighing assembly caused by the too fast speed of the material entering the first storage bin 1, or the failure of some weighing sensors, or the local arrangement of the weighing sensors and the eccentric setting of the center of gravity of the first storage bin 1, and more comprehensively and accurately judges the change of the material in the first storage bin 1.

[0057] Similarly, the weighing assembly arranged on the second storage bin 2 can also be arranged with reference to the setting form of the weighing assembly on the first storage bin 1. For example, a plurality of weighing sensors 4 are arranged at the second feed inlet 24 and the second discharge outlet, and in the area of the second storage bin 2 located between the second feed inlet 24 and the second discharge outlet.

[0058] The setting of the switch assembly enables the operator or the controller signal-connected to the switch assembly and capable of controlling the switch assembly to close the first discharge outlet and / or the second discharge outlet to timely close and open the first discharge outlet and / or the second discharge outlet according to the feedback of the weighing assembly, thus accurately controlling the amount of material conveyed from the first storage bin 1 to the second storage bin 2, and / or the amount of material conveyed from the second storage bin 2 to corresponding equipment such as a concrete mixer.

[0059] The first switch unit and the second switch unit have multiple settings. Taking the first switch unit as an example, the first switch unit includes a first valve, such as a solenoid valve, disposed at the first discharge port for controlling the opening and closing of the first discharge port; or the first switch unit includes a first cover plate disposed at the first discharge port, and the area of the first cover plate needs to be larger than the first discharge port to ensure that when the first cover plate covers the first discharge port, the first cover plate can effectively block the first discharge port. The first switch unit also includes a second driving member that is transmission-connected to the first cover plate and can drive the first cover plate to move or rotate in a direction away from and close to 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 driven by the second driving member to rotate in the direction away from and close to the first discharge port, thereby realizing the closing and opening of the first discharge port, and realizing the control of 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 member can be a linear driving device such as a hydraulic cylinder or a cylinder; or, the second driving member drives the first cover plate to move in the direction away from and close to the first discharge port. At this time, the second driving member can be a linear driving device such as a hydraulic cylinder or a cylinder, and at this time, the first cover plate can be slidably matched with the first storage bin 1, or not be arranged on the first storage bin 1, but it is necessary to ensure that the first discharge port is located on the moving trajectory of the first cover plate, so that the first cover plate can block the first discharge port.

[0060] The second switch unit can be arranged with reference to the arrangement of the first switch unit above, for example, the second switch unit includes a second valve arranged at the second discharge port, and the second valve can be a solenoid valve; or the second switch unit includes a second cover plate arranged at the second discharge port, and a driving device such as a hydraulic cylinder that can drive the second cover plate to move toward and away from the second discharge port to open and close the second discharge port. Figure 4 As shown, the third switch unit includes a third valve 5 arranged at the second discharge port, and a driving 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. At this time, the third valve 5 can be specifically a gate valve (also called a gate valve), and the driving structure 15 can be specifically a structure such as a cylinder or a hydraulic cylinder.

[0061] The first storage bin 1 has a first feed port which is in communication with the first storage bin 1 and is used to fill materials into the first storage bin 1. The feeding system includes a loading assembly for filling materials into the first feed port. External materials can be transported into the first storage bin 1 through the loading assembly to timely replenish the materials in the first storage bin 1. The loading assembly has various forms. For example, the loading assembly can be a conveyor belt, and the bagged or canned materials can be directly poured onto the conveyor belt, and the conveyor belt transports the materials into the first feed port. Alternatively, the loading assembly can be a pipeline connected to the first feed port, and a delivery pump for pumping materials is provided on the pipeline. By pouring the materials into the pipeline, the delivery pump transports the materials into the first storage bin 1.

[0062] Alternatively, the feeding component may not adopt the above structure. The feeding component includes a material gripping member for gripping and releasing materials, and a driving unit for driving the material gripping member to move to the first feeding port. For example, the feeding component may be a manipulator with multiple degrees of freedom. A container capable of holding materials, such as a receiving cylinder with an opening, is provided at the end of the manipulator. At this time, the manipulator can drive the receiving cylinder to rotate, making the opening of the receiving cylinder face upward or downward, and can drive the receiving cylinder to move in multiple directions in space, so that the receiving cylinder can collect materials from an external material storage tank and fill the materials into the first storage bin 1. At this time, the driving unit is a manipulator with multiple degrees of freedom, and the material gripping member is the receiving cylinder. The manipulator can refer to the handling robot in the prior art, and the specific structure will not be elaborated here.

[0063] Alternatively, the material gripping member includes a support 6, and the following are provided on the support 6: several jaws 7 that cooperate with each other to grip and release packaged materials and are rotatably connected to the support 6. A driver 8 is provided on the support 6 and is connected to the jaws 7 to drive the jaws 7 to perform the actions of gripping and releasing materials of the material gripping member, which enables the material gripping member to smoothly grip and release the packaged materials; and a cutting member for cutting the outer package of the material is provided at the first feeding port. Specifically, the cutting member can be provided directly above the first feeding port or in the same plane as the first feeding port. In this way, when the material gripping member grips the packaged material and moves it to the cutting member, and the outer package of the material contacts the cutting member, the outer package of the material is cut by the cutting member, and the material leaks out of the outer package and enters the first storage bin 1. And as the material in the outer package continuously flows out, the driver 8 can control the material gripping member to gradually increase the clamping force on the packaged material, that is, the outer package, thereby reducing the problem that the outer packaging bag enters the first storage bin 1 along with the material due to the too fast material outflow speed and insufficient clamping force, interfering with the feeding and discharging of the first storage bin 1; a pushing plate 9 is also provided on the support 6 and is arranged in an avoiding manner with the jaws 7, and a vibrator 20 is connected to the pushing plate 9 to drive the pushing plate 9 to vibrate. When the material gripping member clamps the packaged material, the outer package of the material abuts against the pushing plate 9. This enables the outer package of the packaged material to be continuously in contact with the pushing plate 9 after being cut by the cutting member because the driving unit gradually increases the clamping force on the packaged material through the material gripping member, that is, the vibrator 20 can drive the material in the outer package to vibrate continuously through the pushing plate 9, ensuring that the material in the outer package can all enter the first storage bin 1 and avoiding waste of materials.

[0064] Among them, the driver 8 can specifically be a rotating motor or a hydraulic cylinder, etc., which can drive the gripper 7 to perform clamping and opening actions. The cutting member can specifically be a cutter 19 provided at the first feed inlet. The cutter 19 can be a fixed cutter, or a cutter 19 that can be rotated by a driving device 22 such as a rotating motor; the vibrator 20 can specifically be a driving device 22 such as a cylinder or a hydraulic cylinder, etc., which can drive the pusher plate 9 to move in the direction close to and away from the outer package. In this way, when the vibrator 20 drives the packaging materials to vibrate through the pusher plate 9, it can be realized by driving the vibrating plate to reciprocate in the direction close to and away from the outer package by the vibrator 20, and the amplitude of the reciprocating movement of the pusher plate 9 needs to be controlled within a small range to avoid the problem that the pusher plate 9 moves too large a distance and pushes the packaging materials that have not been completely discharged off the material gripping member; and when the materials in the outer package are emptied, the vibrator 20 can drive the pusher plate 9 to move in the direction close to the outer package, and then push the outer package off the material gripping member, thus avoiding the problem that the outer package with emptied materials adheres to the gripper 7 and cannot fall off due to the material gripping member clamping the outer package too tightly, so as to facilitate the material gripping member to load the next packaging material. Packaging materials refer to materials with outer packages such as bags or cans.

[0065] The avoidance setting of the gripper 7 and the pusher plate 9 means that the respective functions of the pusher plate 9 and the gripper 7 do not interfere with each other and can be smoothly realized respectively. The gripper 7 also has various setting forms. For example, one end of the gripper 7 for contacting the outer package of the packaging material has sufficient strength to cut through the outer package (at this time, the end of the gripper 7 for contacting the outer package can be a tip so that the gripper 7 can break through the outer package). At this time, before the material gripping member moves to the first feed inlet, the driving unit needs to control the movement of the gripper 7 so that the gripper 7 clamps the packaging material without cutting through the outer package of the material. After the packaging material moves to the first feed inlet and contacts the cutting member, the driving unit can make the material gripping member gradually increase the clamping force on the packaging material, and then make the gripper 7 penetrate into the outer package, thereby increasing the rate at which the material flows from the outer package into the first storage bin 1; or, one end of the gripper 7 for contacting the outer package is not sufficient to cut through the outer package, and in this case, the outer package is only cut through by the cutting member.

[0066] Moreover, a filter screen 10 is provided at the first feed inlet. The diameter of the filter holes of the filter screen 10 is larger than the particle size of the material and smaller than the size of the outer packaging of the material. This enables only the material to pass through the filter screen 10 and enter the first storage bin 1 after the outer packaging is cut. Due to the clamping of the clamping claws 7 and the interception of the filter screen 10, the outer packaging will not enter the first storage bin 1, thereby preventing the outer packaging from entering the first storage bin 1 and reducing the problem of the discharge rate of the first storage bin 1. Specifically, the cutting member can be arranged side by side with the filter screen 10 in the horizontal direction. With the volume of the first storage bin 1 remaining unchanged, this reduces the occupied space of the first storage bin 1 in the vertical direction. Alternatively, the cutting member can be arranged above the filter screen 10 to prevent the fragments of the outer packaging from entering the first storage bin 1 through the gap between the cutting member and the first storage bin 1.

[0067] The base is provided with a feeding area 11 for placing packaging materials and a collection area 12 for placing empty packages of emptied materials. The feeding area 11 can be just a blank area on the base; or, as Figure 1 、 Figure 2 shown, the top of the bracket 17 is the feeding area 11. A number of sleeves with internal threads are provided below the bottom of the bracket 17. The sleeves are internally threaded with legs, and the number of legs corresponds to the number of sleeves. The legs are provided with external threads. When the height of the bracket 17 needs to be adjusted, the legs can be rotated. Similarly, the collection area 12 can be a blank area on the base, or a bracket 17 can also be set to place the outer packaging of the emptied materials. The base is also provided with a frame. A slide rail 21 is provided at the top of the frame along the horizontal direction (i.e., the direction from the feeding area 11 to the collection area 12), a slide plate 23 (or called a trolley) that is slidably matched with the slide rail 21, and a third driving member 13 for driving the slide plate 23 to move bidirectionally between the feeding area 11 and the collection area 12. A fourth driving member 14 is provided at the bottom of the slide plate 23. The fourth driving member 14 is connected with a scissor expansion frame 18, and one end of the scissor expansion frame 18 far from the fourth driving member 14 is connected with a support 6. Among them, when the third driving member 13 is connected to the bracket 17 of the slide plate 23, the third driving member 13 can be a linear driving device such as a cylinder; or, a rack can also be arranged on the slide plate 23 along the direction from the feeding area 11 to the collection area 12. At this time, the third driving member 13 can be a rotary motor, and the rotary motor is connected with a gear that meshes with the rack. And within the stroke of the slide plate 23, the rack can maintain meshing with the gear. In this way, the rotary motor drives the gear to rotate, and the gear drives the rack to move towards or away from the collection area 12. The fourth driving member 14 can be a linear driving device such as a cylinder. Driving the scissor expansion frame 18 to stretch and contract by a linear driving device is an existing technology, and the specific connection relationship between the fourth driving member 14 and the scissor expansion frame 18 will not be elaborated.

[0068] As Figure 1 、 Figure 2 、 Figure 3As shown, this is the specific structure under an embodiment of the present invention. At this time, only the second storage bin 2 is provided with a weighing component, and a third switching unit is provided at the second discharge port. 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 conveying device such as a pumping pipeline or a conveyor belt. Then, the conveying component 3, the switching component, and the rotary cutter are started. After an operator or a handling machine such as a forklift places the outer packaging material on the top of the bracket 17, the third driving member 13 drives the sliding plate 23 to move directly above the bracket 17. The fourth driving member 14 drives the clamping jaw 7 to move towards the outer packaging material above the bracket 17 by stretching the scissor-type telescopic frame 18. The driver 8 drives the clamping jaw 7 to clamp the outer packaging material. The fourth driving member 14 contracts the scissor-type telescopic frame 18 to lift the outer packaging material above the first storage bin 1. Subsequently, the third driving member 13 drives the sliding plate 23 and the outer packaging material to move directly above the first feeding port. The fourth driving member 14 stretches the scissor-type telescopic frame 18 to make the outer packaging material gradually approach the rotary cutter at the first feeding port. After the rotary cutter cuts through the outer packaging, the material gradually falls into the first storage bin 1 from the outer packaging. At the same time, the driver 8 controls the clamping jaw 7 to gradually tighten, increasing the clamping force on the outer packaging to ensure that the outer packaging does not enter the first storage bin 1 along with the outer packaging. At this time, the conveying component 3 can be a screw conveyor 25, and the material in the first storage bin 1 is gradually conveyed into the second storage bin 2 through the screw conveyor 25. The controller or the operator judges whether the material conveyed by the second storage bin 2 to the equipment to be fed reaches the required value according to the feedback of the weighing sensor. When it is about to reach the required value, the second discharge port is timely closed through the third switching unit to ensure the accuracy of the material quantity conveyed by the second storage bin 2 to the equipment to be fed. After all the material in the outer packaging has fallen into the first storage bin 1, the third driving member 13 drives the sliding plate 23 and the outer packaging to move above the collection area 12. The fourth driving member 14 stretches the scissor-type telescopic frame 18 to place the empty packaging with the emptied material in the collection area 12. Subsequently, the fourth driving member 14 contracts the scissor-type telescopic frame 18 upward, and the third driving member 13 drives the sliding plate 23 to move towards the feeding area 11 for subsequent feeding of packaging materials.

[0069] As Figure 6 、 Figure 7As shown, two oppositely arranged mounting seats are provided at the bottom of the support 6, and a rotating rod is rotatably connected in the mounting seat, and two clamping claws 7 are respectively fixed at both ends of the rotating rod, and 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 relatively arranged; when the two drivers 8 respectively drive the two crank arms 16 to rotate in opposite directions, they then drive the two rotating rods and the clamping claws 7 on both sides to rotate in opposite directions, thereby achieving the clamping of the grasping piece; 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 clamping claws 7 to rotate in opposite directions, thereby achieving the release of the grasping piece; wherein the driver 8 can specifically be a linear driving device such as a cylinder or a hydraulic cylinder; if the crank arm 16 is not provided, the driver 8 can also be connected to the end of the rotating rod, and the rotating rod is directly driven to rotate by the driver 8. At this time, the driver 8 can be a rotating driving device such as a rotating motor.

[0070] The support 6 and the push plate 9 are provided with a plurality of hollow holes to reduce the weight of the material grabbing member and reduce energy consumption; the shape of the hollow holes is not limited, and can be circular, triangular, etc., but it should be noted that the setting of the hollow holes shall not significantly reduce the strength of the support 6 and the push plate 9 to ensure the smooth operation of the two. Figure 2 As shown, the second storage bin 2 is arranged at one side of the first storage bin 1 and is adjacent to the first storage bin 1, which makes the first storage bin 1 and the second storage bin 2 more compact and reduces the occupied space of the feeding system.

[0071] Furthermore, the feeding system in the present invention also includes a discharging component, which includes a material discharging member 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 the second storage bin 2, and a fifth driving member transmission-connected to the material discharging member and used to drive the material discharging member to rotate. The material discharging member is driven to rotate by the third driving member 13, which can reduce the accumulation of materials in the first storage bin 1 and / or the second storage bin 2 and ensure the smooth flow of materials in the first storage bin 1 and / or the second storage bin 2; the material discharging member can specifically be a material discharging roller, a material discharging plate, a material discharging rod or other structures, and the fifth driving member can specifically be a rotating driving device such as a rotating motor that can drive the material discharging member to rotate.

[0072] And / or, the discharging assembly includes a vibrator 20 disposed outside the first storage bin 1 and connected to the first storage bin 1. When it is found that the first storage bin 1 or the second storage bin 2 does not discharge or the discharging speed is slow, the vibrator 20 is started. The vibrator 20 can drive the corresponding storage bin in the first storage bin 1 and the second storage bin 2 to vibrate, reducing the adhesion and accumulation of materials in the first storage bin 1 or the second storage bin 2, and ensuring the accuracy of the discharging amount; specifically, the vibrator 20 may include a vibration motor connected to the first storage bin 1. And / or, the discharging assembly includes a conveying pipeline connecting the second discharging port to the equipment to which the material to be added is to be added. A plurality of air inlets are provided at intervals along the conveying direction of the material on the conveying pipeline, and a medium source communicating with the air inlets and used for supplying a conveying medium; under the push of the subsequent material, the material in the second storage bin 2 is gradually pushed out. Or, a stirring shaft driven by a motor may be provided in the second storage bin 2 to accelerate the discharging speed of the material. After the material in the second storage bin 2 enters the conveying pipeline, it is conveyed to the equipment to which the material to be added is to be added by the conveying medium. The spaced air inlets form a plug flow conveying, that is, a section of conveying medium and a section of material, which effectively reduces the abrasion during the material conveying process; specifically, the medium source may be a gas source such as a nitrogen storage tank that can supply an inert gas that does not react with the material to the conveying pipeline, and a conveying pump provided at the air outlet of the nitrogen storage tank.

[0073] An anti-adhesion coating provided on the inner wall of the first storage bin 1 and / or the inner wall of the second storage bin 2 reduces the material adhering to the first storage bin 1 and / or the second storage bin 2. Specifically, the anti-adhesion coating may be a polytetrafluoroethylene coating. And / or, the first feeding port is higher than the first discharging port, and the side inclination angle of the first storage bin 1 is greater than the angle of repose of the material in the first storage bin 1, which enables the material in the first storage bin 1 to have a tendency to move automatically in the direction of the first discharging port under the action of the component of its own gravity along the direction of the bin wall of the first storage bin 1, reducing the accumulation of materials in the first storage bin 1.

[0074] In the present invention, the weighing assembly, the switch assembly, the conveying assembly 3, the feeding assembly, and the discharging assembly are all signal-connected to a controller. The controller is used to receive an external feeding signal and control the weighing assembly, the switch assembly, the conveying assembly 3, the feeding assembly, and the discharging assembly to perform corresponding actions, and then accurately add the required amount of material into corresponding equipment such as a concrete mixer.
