Its core function is to continuously measure, accumulate, and manage the weight of materials in real time and accurately during the material transmission process. It is widely used in industries such as grain, mining, ports, and chemicals that require continuous conveying and weight monitoring of bulk materials.

[0003] The prior art discloses a dynamic weighing device for belt conveyors (CN202420130109.6). The main module includes symmetrically arranged side plates, multiple weighing sensors installed on the inner walls of the side plates, a conveyor component movably installed between opposite side plates and extending into the side plates, a push-out assembly installed on one side of the top of the conveyor component, a discharge plate installed on the other side of the top of the conveyor component, U-shaped frames symmetrically fixed at both ends of the side plates, a second electric push rod installed at the bottom of one side of the U-shaped frame and extending through the U-shaped frame, a rectangular plate movably fitted into one side of the U-shaped frame and fixedly connected to the second electric push rod, and a photoelectric sensor installed at the top of the U-shaped frame. The side plates are used to install the weighing sensors to ensure the stability of the weighing sensors. Grooves are symmetrically opened on the inner side of the side plates, and the weighing sensors are installed on the inner bottom wall of the grooves.

[0004] In existing technology, items are moved from the conveyor system onto the main body of the conveyor belt. The weight of the items on the main body of the conveyor belt is transmitted to the weighing sensor, which weighs the items. However, the conveyor belt may deviate from the center of the conveyor belt. If the items deviate from the center of the conveyor belt, the weight detected by the weighing sensor will be unstable, resulting in inaccurate weighing data.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the aforementioned technical problem of inaccurate weighing data, the basic concept of the technical solution adopted by this utility model is as follows: a conveyor belt body, the conveyor belt body is set above the ground, a push plate is set on one side of the conveyor belt body, a rectangular plate is set on the other side of the conveyor belt body, and a discharge plate is set opposite the push plate. The centering measuring structure is located above the main body of the conveyor belt, and four retracting rods are installed above the main body of the conveyor belt to keep the fertilizer barrels centered.

[0007] In a preferred embodiment of the present invention, a circular plate is provided above the conveyor belt body, and four grooves are provided on the top surface of the circular plate. A movable block is provided inside each groove. The movable block is H-shaped and its middle part is slidably connected to the groove.

[0008] In a preferred embodiment of this utility model, the centering measurement structure further includes a central block, a transmission rod, and a circular block. A circular block is provided on the top surface of each moving block, and each circular block is rotatably connected to the moving block. The transmission rod is L-shaped and there are four of them. One end of each transmission rod is fixedly connected to one side of the circular block, and the other end of each transmission rod is rotatably connected to one corner of the central block. An infrared sensor is provided below the central block.

[0009] In a preferred embodiment of this utility model, the bottom surface of the central block is rotatably connected to the top surface of the circular plate.

[0010] In a preferred embodiment of the present invention, a bracket is fixedly mounted on the top surface of the circular plate. The bracket is N-shaped, and a first servo motor is fixedly mounted on the top surface of the bracket. The output shaft of the first servo motor is fixedly connected to the top surface of the center block through a coupling.

[0011] In a preferred embodiment of this utility model, the centering measuring structure further includes a retracting rod, with the bottom surface of each moving block fixedly connected to the top surface of a retracting rod, and each retracting rod being L-shaped.

[0012] In a preferred embodiment of this utility model, a U-shaped frame is provided below the conveyor belt body, and a support rod is fixed at each end of the U-shaped frame, with the two support rods fixedly connected to the circular plate.

[0013] Compared with the prior art, the present invention has the following advantages: 1.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0019] A combined weighing belt conveyor, such as Figure 1 and Figure 5As shown, a conveyor belt body 1 is positioned above the ground. A push plate 2 is located on one side of the conveyor belt body 1, and a rectangular plate 3 is located on the other side. A discharge plate 4 is located opposite the push plate 2. A U-shaped frame is located below the conveyor belt body 1, with a support rod 14 fixed at each end of the U-shaped frame. The two support rods 14 are fixedly connected to a circular plate 5. A combined weighing belt conveyor also includes a main module, side plates, grooves, weighing sensors, conveying components, protrusions, ejection components, baffles, a first electric push rod, a chute, a second electric push rod, a photoelectric sensor, a transmitter, and a receiver. The above structure, along with the conveyor belt body 1, push plate 2, rectangular plate 3, discharge plate 4, and U-shaped frame, are all prior art and have been disclosed in a dynamic weighing device for belt conveyors (CN202420130109.6). Specific embodiments are not described here. In use, items are moved from the conveying system onto the conveyor belt body 1. When an item enters the conveyor belt body 1, the photoelectric sensor on the side near the rectangular plate 3 detects the item's passage. After the item passes, the second electric push rod is activated, causing the rectangular plate 3 to rise and block adjacent items outside the conveyor belt body, preventing interference from adjacent items during weighing and ensuring weighing accuracy. At this time, the weight of the item on the conveyor belt body 1 is transmitted to the weighing sensor, which weighs the item and outputs the weight data. Then, the conveyor belt body 1 sends the item back to the transportation system. Simultaneously, when the photoelectric sensor on the other side detects that an item has been sent off the conveyor belt body 1, the second electric push rod causes the rectangular plate 3 to retract, facilitating the weighing of the next item. In addition, after weighing the item, if the weight of the item is detected to be greater than a predetermined value, the first electric push rod is activated, causing the push plate 2 to extend and push the item on the conveyor belt body 1 out of the discharge plate 4, preventing damage caused by overloading of the subsequent belt conveyor.

[0020] A combined weighing belt conveyor, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a centering measuring structure is positioned above the conveyor belt body 1. Four converging rods 7 are positioned above the conveyor belt body 1 to keep the fertilizer buckets centered. A circular plate 5 is positioned above the conveyor belt body 1, with four grooves 11 on its top surface. Each groove 11 contains a movable block 10, which is H-shaped and slidably connected to the groove 11. The centering measuring structure also includes a center block 8, a transmission rod 9, and circular blocks 12. Each movable block 10 has a circular block 12 on its top surface, and each circular block 12 is rotatably connected to the movable block 10. The transmission rod 9 is L-shaped and has four... Each transmission rod 9 has one end fixedly connected to one side of the circular block 12, and the other end of each transmission rod 9 rotatably connected to one corner of the central block 8. An infrared sensor is installed below the central block 8. The bottom surface of the central block 8 is rotatably connected to the top surface of the circular plate 5. A bracket 13 is fixedly installed on the top surface of the circular plate 5. The bracket 13 is N-shaped. A first servo motor 6 is fixedly installed on the top surface of the bracket 13. The output shaft of the first servo motor 6 is fixedly connected to the top surface of the central block 8 through a coupling. The central measuring structure also includes a retracting rod 7. The bottom surface of each moving block 10 is fixedly connected to the top surface of a retracting rod 7. Each retracting rod 7 is L-shaped.

[0021] When the rectangular plate 3 rises, the first servo motor 6 is activated. The first servo motor 6 drives the central block 8 to rotate, which in turn drives the four transmission rods 9 to rotate. The four transmission rods 9 pull the four circular blocks 12, which in turn drive the four moving blocks 10 to move within the slide 11. The four moving blocks 10 then drive the four gathering rods 7 to move towards the center. The fertilizer box is gathered to the center of the conveyor belt body 1. When the infrared sensor below the central block 8 detects that the object is in the center, the controller drives the first servo motor 6 to reverse. The first servo motor 6 drives all the gathering rods 7 to reset. The object is in the conveyor belt body 1, and the weight can be evenly distributed. The weight detected by the central weighing sensor is more stable and balanced, and the central weighing sensor can weigh the object more accurately. The four gathering rods 7 can reset when the object is gathered to the center. This design is suitable for fertilizer boxes of different sizes and facilitates the use of fertilizer boxes of various specifications.

[0022] The working principle of this utility model is as follows: When the rectangular plate 3 is raised, the first servo motor 6 is started. The first servo motor 6 drives the central block 8 to rotate. The central block 8 drives the four transmission rods 9 to rotate. The four transmission rods 9 pull the four circular blocks 12. The four circular blocks 12 drive the four moving blocks 10 to move in the slide 11. The four moving blocks 10 drive the four gathering rods 7 to move towards the center. The fertilizer box is gathered to the center of the conveyor belt body 1. When the infrared sensor below the central block 8 detects that the object is in the center, the controller drives the first servo motor 6 to reverse. The first servo motor 6 drives all the gathering rods 7 to reset. The object is in the conveyor belt body 1, and the weight can be evenly distributed. The weight detected by the central weighing sensor is more stable and balanced. The central weighing sensor can weigh the object more accurately. The four gathering rods 7 can reset when the object is gathered to the center. It is suitable for fertilizer boxes of different sizes and is convenient for use in fertilizer boxes of various specifications.
