A support plate is provided, and the support plate is used to support the top of the inner wall of the conveyor belt. A through hole is opened in the middle of the conveyor frame, which is compatible with the middle protrusion of the mountain-shaped plate. A single roller is driven to rotate by a motor. Under the transmission action of the two rollers, the two rollers drive the conveyor belt to rotate, and the conveyor belt will transport the goods to the position above the weighing equipment body. Then, the hydraulic cylinder is started, and the telescopic end of the hydraulic cylinder drives the conveyor frame to move downward. The conveyor frame drives the two conveyor belts to move downward through the rollers, and the conveyor belts move into the two recesses of the mountain-shaped plate. At the same time, the conveyor belt will place the goods on the top of the weighing equipment body. At this time, the weighing equipment body can weigh the goods. A re-weighing device is provided in the middle of the bottom plate, and the re-weighing device includes two groove plates. The two grooves The groove plates are respectively fixed on both sides of the top of the bottom plate, and a bidirectional screw is rotatably installed inside the front groove plate, and the bidirectional screw is driven by a motor, and a sliding column is fixed inside the rear groove plate, and both sides of the outside of the bidirectional screw are threadedly connected with U-shaped plates, and one end of the two U-shaped plates away from the bidirectional screws is slidably installed on the outside of the sliding column, and elastic telescopic rods are fixed on both sides of the two U-shaped plates away from each other, and the telescopic ends of the two adjacent elastic telescopic rods are horizontally penetrated and slidably installed on the side, and a spring is provided between the plug rod and the telescopic end of the elastic telescopic rod, and a center plate is fixed at the bottom of the plug rod, and a hinged rod is hinged at the bottom of the center plate, and the end of the hinged rod away from the center plate is hinged to the U-shaped plate The outer wall of the weighing device is driven by a motor to rotate the bidirectional screw, which drives the two U-shaped plates to move along the outside of the sliding column toward the center of the weighing device body. The two U-shaped plates drive the center plate to move along through the elastic telescopic rod 1 and the plug rod. The center plate will push the goods on the weighing device body to the center position of the weighing device body. When the center plate contacts the outer wall of the goods, the U-shaped plate continues to push the center plate to move through the elastic telescopic rod 1 and the plug rod. At this time, the U-shaped plate pushes the center plate upward through the hinged rod, and the center plate drives the telescopic end of the elastic telescopic rod 1 to move upward through the plug rod. In this process, the two center plates will lift the goods, and the bottom surface of the goods will not contact the top of the weighing device body. Then, the motor drives the bidirectional screw to rotate in the same direction.The bidirectional screw drives the two U-shaped plates to move along the outside of the slide column away from the center of the weighing device body, and the U-shaped plates drive the centering plate to reset, and the centering plate will place the goods in the center of the weighing device body.

[0007] According to the above technical solution, a through groove is opened in the middle of the centering plate, a connecting column is fixed at the middle inner wall of the through groove of the centering plate, and an elastic arc plate is fixed on the side of the connecting column close to the center of the bottom plate. At the same time, when the centering plate moves toward the center of the main body of the weighing equipment, the centering plate drives the elastic arc plate to approach the goods through the connecting column first, and under the guidance of the arc surface of the elastic arc plate, the arc surface of the elastic arc plate helps push the goods in the front and rear directions.

[0008] According to the above technical scheme, a spacing device is arranged above the groove plate on the front side, and the spacing device includes a telescopic arc top plate and two bidirectional telescopic rods. The fixed end of the telescopic arc top plate is fixed to the middle of the top surface of the groove plate on the front side, and the telescopic arc top plate is located below the through-opening of the transmission frame. One end of the two bidirectional telescopic rods are respectively hinged on both sides of the telescopic end of the telescopic arc top plate, and the other ends of the two bidirectional telescopic rods are respectively hinged on one side of the two U-shaped plates close to each other. In the process of the two U-shaped plates moving along the outside of the sliding column toward the center of the main body of the weighing equipment, the two U-shaped plates respectively push one end of the bidirectional telescopic rod to move along, and the other end of the bidirectional telescopic rod pushes the telescopic end of the telescopic arc top plate to move upward, and the arc surface of the telescopic end of the telescopic arc top plate will push the goods on the front side of the goods to be weighed to move in the direction away from the main body of the weighing equipment.

One end of the one-way telescopic rod is hinged to the bottom front side of the push plate, and the other end of the one-way telescopic rod is hinged to the top of the bottom plate. At the same time, when the telescopic end of the telescopic arc top plate moves upward, the telescopic end of the telescopic arc top plate drives the push plate to move upward through the positioning rod.

At the same time, when the U-shaped plate is driven to move by the bidirectional screw driven by the motor, the U-shaped plate drives the L-shaped column to move with it, and the cylindrical shape of the L-shaped column pushes the semi-arc blocks of the arc block plate to drive the L-shaped pull rod to move downward, and the L-shaped pull rod drives the pressure column to move downward, and the pressure column squeezes the bottom of the inner wall of the conveyor belt, so that the bottom of the inner wall of the conveyor belt bulges downward and deforms.

[0028] A spacing device 4 is arranged above the front groove plate 31, and the spacing device 4 includes a telescopic arc top plate 42 and two bidirectional telescopic rods 41. The fixed end of the telescopic arc top plate 42 is fixed to the middle of the top surface of the front groove plate 31, and the telescopic arc top plate 42 is located below the through opening of the transmission frame 7. One end of the two bidirectional telescopic rods 41 is respectively hinged on both sides of the telescopic end of the telescopic arc top plate 42, and the other ends of the two bidirectional telescopic rods 41 are respectively hinged on the side where the two U-shaped plates 33 are close to each other. Through the arrangement of the above structure, the arc surface of the telescopic end of the telescopic arc top plate 42 will push the goods on the front side of the goods to be weighed to move away from the weighing equipment body 6, thereby avoiding the problem that the conveyor belt 9 carries the goods on the front side and the goods to be weighed and falls on the weighing equipment body 6 at the same time, affecting the weighing of the goods by the weighing equipment body 6.

[0029] The spacing device 4 also includes a push plate 43, two positioning rods 44, and a one-way telescopic rod 45. The two positioning rods 44 are fixed on the front side of the telescopic end of the telescopic arc top plate 42. The push plate 43 is slidably installed on the outside of the two positioning rods 44, and a spring is provided between the front side of the push plate 43 and the positioning rods 44. One end of the one-way telescopic rod 45 is hinged to the bottom of the front side of the push plate 43, and the other end of the one-way telescopic rod 45 is hinged to the top of the bottom plate 1. Through the setting of the above structure, the one-way telescopic rod 45 will pull the push plate 43 along the outer wall of the positioning rod 44 to move away from the telescopic arc top plate 42, so that the push plate 43 further pushes the goods on the front side, ensuring that there is enough transmission spacing between the two adjacent goods, and then after the previous goods are weighed and transmitted, the next goods can be moved just to the upper position of the weighing equipment body 6, thereby avoiding interference between goods and ensuring that each goods can be smoothly moved to the upper position of the weighing equipment body 6.

[0030] When in use, when the goods need to be weighed, the goods are placed on the conveyor belt 9, and the single roller 8 is driven to rotate by the motor. Under the transmission action of the two rollers 8, the two rollers 8 drive the conveyor belt 9 to rotate, and the conveyor belt 9 will transport the goods to the position above the weighing device body 6. Then, the hydraulic cylinder 2 is started, and the telescopic end of the hydraulic cylinder 2 drives the conveyor frame 7 to move downward. The conveyor frame 7 drives the two conveyor belts 9 to move downward through the rollers 8, and the conveyor belts 9 move into the two recesses of the mountain-shaped plate 11. At the same time, the conveyor belt 9 will place the goods on the top of the weighing device body 6. At this time, the weighing device body 6 can weigh the goods, and at the same time, when the goods are placed After reaching the top of the weighing device body 6, the bidirectional screw 32 is driven by a motor to rotate, and the bidirectional screw 32 drives the two U-shaped plates 33 to move along the outside of the sliding column 34 toward the center of the weighing device body 6. The two U-shaped plates 33 drive the center plate 39 to move along through the elastic telescopic rod 1 35 and the insertion rod 36. The center plate 39 will push the goods on the weighing device body 6 to the center position of the weighing device body 6. When the center plate 39 contacts the outer wall of the goods, the U-shaped plate 33 continues to push the center plate 39 to move through the elastic telescopic rod 1 35 and the insertion rod 36. At this time, the U-shaped plate 33 pushes the center plate 39 to move upward through the hinged rod 310, and The centering plate 39 drives the telescopic end of the elastic telescopic rod 35 to move upward through the insertion rod 36. During this process, the two centering plates 39 will lift the goods, and the bottom surface of the goods will not contact the top of the weighing device body 6. Then, the motor drives the bidirectional screw 32 to rotate, and the bidirectional screw 32 drives the two U-shaped plates 33 to move along the outside of the sliding column 34 in the direction away from the center of the weighing device body 6. The U-shaped plate 33 drives the centering plate 39 to reset, and the centering plate 39 will place the goods in the center of the weighing device body 6, thereby ensuring that after the goods are weighed once, they are placed again in the center of the weighing device body 6 for re-weighing, which can help Confirm the accuracy of the first weighing. At the same time, compared with the method of directly pushing the goods to move to the center on the weighing device body 6, the method of lifting the goods and placing them in the center position of the weighing device body 6 can more accurately reflect the weight of the goods after re-weighing; at the same time, when the centering plate 39 moves toward the center of the weighing device body 6, the centering plate 39 drives the elastic arc plate 37 to approach the goods through the connecting column 38. Under the guidance of the arc surface of the elastic arc plate 37, the arc surface of the elastic arc plate 37 helps push the goods in the front and rear directions, thereby helping the goods to be accurately aligned with the center position of the weighing device body 6 in the front and rear directions, thereby improving the accuracy of cargo weighing.

[0031] In the process of the two U-shaped plates 33 moving along the outside of the sliding column 34 toward the center of the weighing device body 6, the two U-shaped plates 33 respectively push one end of the two-way telescopic rod 41 to move along, and the other end of the two-way telescopic rod 41 pushes the telescopic end of the telescopic arc top plate 42 to move upward, and the arc surface of the telescopic end of the telescopic arc top plate 42 will push the goods in front of the goods to be weighed to move away from the weighing device body 6, thereby avoiding the problem that the conveyor belt 9 carries the goods in front and the goods to be weighed and falls on the weighing device body 6 at the same time, affecting the weighing of the goods by the weighing device body 6; at the same time, when the telescopic end of the telescopic arc top plate 42 moves upward, the telescopic end of the telescopic arc top plate 42 The push plate 43 is driven upward by the positioning rod 44. Since the position of the push plate 43 is restricted by the one-way telescopic rod 45, during the upward movement of the push plate 43, the one-way telescopic rod 45 will pull the push plate 43 along the outer wall of the positioning rod 44 to move away from the telescopic arc top plate 42, so that the push plate 43 can further push the goods on the front side, ensuring that there is enough transmission distance between the two adjacent goods, and then after the previous goods are weighed and transmitted, the next goods can be moved to the upper position of the weighing device main body 6, thereby avoiding interference between the goods and ensuring that each goods can be smoothly moved to the upper position of the weighing device main body 6.

The movable rod is slidably installed inside the fixed sleeve, and the spring is fixed between the movable rod and the inner wall of the fixed sleeve. Through the setting of the above structure, the scraper 52 scrapes impurities on the surface of the conveyor belt 9, thereby preventing impurities from falling onto the weighing device body 6, thereby reducing the possibility of contamination of the weighing device body 6, which helps to maintain the normal operation of the weighing device body 6.

The pressure column 53 is fixed between the tops of the two L-shaped pull rods 55, and the pressure column 53 contacts the bottom of the inner wall of the two conveyor belts 9. The arc block plate 56 is fixed on one end of the two L-shaped pull rods 55 away from the horizontal plate 54, and the two L-shaped columns 57 are respectively fixed on the side of the two U-shaped plates 33 close to each other. The L-shaped column 57 is located on the rear side of the U-shaped plate 33, and a number of semi-arc blocks are evenly and equidistantly fixed on the top of the arc block plate 56. The end of the L-shaped column 57 away from the U-shaped plate 33 is cylindrically arranged, and the semi-arc blocks of the arc block plate 56 are located on the cylindrical movement trajectory of the L-shaped column 57. Through the arrangement of the above structure, the L-shaped pull rod 55 drives the pressure column 53 to move downward, and the pressure column 53 squeezes the bottom of the inner wall of the conveyor belt 9, so that the bottom of the inner wall of the conveyor belt 9 bulges and deforms downward, which is beneficial for the scraper 52 to clean foreign matter embedded in the surface of the conveyor belt 9, thereby reducing the wear and damage of the conveyor belt 9 by foreign matter, thereby extending the service life of the conveyor belt 9.

[0035] When in use, during the rotation of the conveyor belt 9, under the elastic force of the elastic telescopic rod 2 51, the telescopic end of the elastic telescopic rod 2 51 drives the scraper 52 to be close to the bottom outer wall of the conveyor belt 9, so that the scraper 52 scrapes off the impurities on the surface of the conveyor belt 9, thereby preventing the impurities from falling onto the weighing device body 6, thereby reducing the possibility of the weighing device body 6 being contaminated, which helps to maintain the normal operation of the weighing device body 6; at the same time, when the U-shaped plate 33 is driven to move by the motor-driven bidirectional screw 32, the U-shaped plate 33 drives the L-shaped column 57 to move along, and the cylindrical shape of the L-shaped column 57 pushes the semi-arc block of the arc block plate 56 to drive the L-shaped pull rod 55 to move downward, and the L-shaped pull rod 55 drives the pressure column 53 to move downward, and the pressure column 53 presses the bottom of the inner wall of the conveyor belt 9 The conveyor belt 9 is extruded, so that the bottom of the inner wall of the conveyor belt 9 bulges and deforms downward, which is beneficial for the scraper 52 to clean foreign objects embedded in the surface of the conveyor belt 9, thereby reducing the wear and damage of the conveyor belt 9 by foreign objects, thereby extending the service life of the conveyor belt 9. It is worth noting that when the conveyor frame 7 drives the two conveyor belts 9 to move downward through the roller 8, the conveyor belt 9 will exert pressure on the top surface of the scraper 52, so that the scraper 52 squeezes the telescopic end of the elastic telescopic rod 2 51, and the telescopic end of the elastic telescopic rod 2 51 is compressed. At the same time, the cross plate 54 drives the L-shaped pull rod 55 to move downward through the spring. Although the L-shaped pull rod 55 here will drive the arc block plate 56 to move downward, the semi-arc block of the arc block plate 56 is still on the cylindrical motion trajectory of the L-shaped column 57.
