[0049] Furthermore, this invention, through the setting of a weighing and extraction mechanism, uses a hydraulic cylinder to drive the extraction connecting plate to rotate.

After extraction is completed, the hydraulic cylinder drives the bagged cement to be lifted, which facilitates the sampling and inspection operation of the bagged cement.

[0050] Furthermore, this invention, through the setting of a weighing transfer mechanism, uses a hydraulic cylinder to drive a gripper mechanism to clamp the bagged cement, and then transports the bagged cement to a weighing and testing scale via a weighing conveyor. This achieves automatic sampling and inspection of bagged cement, avoiding manual operation, reducing the labor burden on workers, improving the efficiency of bagged cement production, ensuring the production quality of bagged cement, and allowing bagged cement to be directly sampled and weighed on the production line, which is convenient for operation.

[0051] Furthermore, by incorporating a weighing dust fan, this invention effectively absorbs dust from the bagged cement during the grasping process, ensuring the environmental friendliness of the entire weighing device during operation and maintaining a clean working environment.

[0052] Furthermore, by setting up a weighing extrusion plate, the piston rod of the weighing drive hydraulic cylinder moves upward, which in turn moves the weighing protection connecting rod upward. This upward movement of the weighing protection connecting rod then moves the weighing drive rack upward, which in turn rotates the weighing drive gear. The rotation of the weighing drive gear then moves the weighing extrusion rack downward, which in turn moves the weighing extrusion plate downward. This downward movement of the weighing extrusion plate extrudes the bagged cement, facilitating the subsequent stacking of the bagged cement.

[0053] This invention facilitates the conveying of bagged cement, avoids manual handling, and enables the lifting of bagged cement. It also facilitates the sampling and inspection of bagged cement, achieving automatic sampling and inspection, eliminating manual operation, reducing the labor burden on workers, improving the efficiency of bagged cement production, and allowing bagged cement to be directly sampled and weighed on the production line. This simplifies operation, ensures the production quality of bagged cement, guarantees the environmental friendliness of the entire sampling and weighing device during operation, and ensures a clean working environment.

[0078] The extraction and moving hydraulic cylinder 401 is fixedly connected to the upper rear end of the extraction and conveying vehicle 4, and the piston rod of the extraction and moving hydraulic cylinder 401 is fixedly connected to the cement conveying support 1.

[0079] Two sets of extraction rotating hydraulic cylinders 402 are provided, and the two sets of extraction rotating hydraulic cylinders 402 are respectively hinged to the left and right ends above the extraction conveyor 4.

[0080] Two sets of extraction support seats 403 are provided. The two sets of extraction support seats 403 are fixedly connected to the upper left and right ends of the extraction conveyor 4, respectively. Both sets of extraction support seats 403 are hinged to the extraction connecting plate 5.

[0081] Two sets of first connecting rods 404 are provided. The front ends of the two sets of first connecting rods 404 are hinged to the piston rod of the extraction rotating hydraulic cylinder 402, and the rear ends of the two sets of first connecting rods 404 are hinged to the extraction connecting plate 5.

[0082] Two sets of second connecting rods 405 are provided.

[0091] The weighing transfer hydraulic cylinder 601 is fixedly connected to the upper rear end of the cement conveying support 1, and the piston rod of the weighing transfer hydraulic cylinder 601 is fixedly connected to the rear end of the weighing conveying vehicle 6.

[0092] Two sets of weighing grippers 604 are provided, and the two sets of weighing grippers 604 are respectively hinged to the left and right sides below the weighing conveyor 6.

[0093] Two sets of weighing gripping connecting rods 605 are provided, and the two sets of weighing gripping connecting rods 605 are welded to the bottom of the weighing gripping component 604 respectively;

[0094] Two sets of weighing and grasping claws 606 are provided. Both sets of weighing and grasping claws 606 are equipped with a slanted claw structure. The two sets of weighing and grasping claws 606 are fixedly connected to the lower end of the weighing and grasping connecting rod 605.

[0095] Two sets of weighing gripping trigger rods 607 are provided. One end of each set of weighing gripping trigger rods 607 is hinged to the piston rod of the weighing drive hydraulic cylinder 603, and the outer side of each set of weighing gripping trigger rods 607 is hinged to the weighing gripping connecting rod 605.

[0096] The weighing protection connecting rod 608 is fixedly connected to the outer periphery of the piston rod of the weighing drive hydraulic cylinder 603;

[0097] The weighing drive rack 609 is fixedly connected to the upper left side of the weighing protection connecting rod 608;

[0098] The weighing dustproof fan 610 is fixedly connected to the left side of the weighing protection connecting rod 608. The weighing dustproof fan 610 has a negative pressure fan structure. The upper end of the weighing dustproof fan 610 is connected to a connecting pipe, which is connected to the outside air system.

[0099] The weighing drive gear 611 is rotatably connected inside the dustproof limit box 602, and the weighing drive gear 611 meshes with the weighing drive rack 609.

[0100] The weighing compression rack 612 is slidably connected to the right side of the weighing protection connecting rod 608, and the weighing compression rack 612 meshes with the weighing drive gear 611;

[0101] The weighing and pressing fixing plate 613 is fixedly connected to the bottom of the weighing and pressing rack 612;

[0104] In use, when it is necessary to weigh the bagged cement component 3 on the extraction connecting plate 5, the weighing drive hydraulic cylinder 603 is activated. The piston rod of the weighing drive hydraulic cylinder 603 moves downward, causing the two sets of weighing gripping trigger rods 607 to rotate. The two sets of weighing gripping trigger rods 607 rotate inward, causing the weighing gripping connecting rod 605 to rotate in opposite directions. The rotation of the weighing gripping connecting rod 605 in opposite directions causes the weighing grasping claw 606 to rotate in opposite directions. The rotation of the weighing grasping claw 606 in opposite directions achieves the gripping of the bagged cement component 3. After the bagged cement component 3 is gripped, the weighing transfer hydraulic cylinder 601 is activated. The piston rod of the weighing transfer hydraulic cylinder 601 moves to the right, which in turn moves the weighing conveyor 6 to the right. The weighing conveyor 6 transports the bagged cement component 3 to the top of the electronic weighing device. At this point, the weighing gripper 606 is opened to place the bagged cement component 3. Simultaneously, as the piston rod of the weighing drive hydraulic cylinder 603 moves downward, the weighing dust fan 610 is activated. The weighing dust fan 610 effectively adsorbs dust from the bagged cement during the gripping process, ensuring the environmental friendliness of the entire weighing device during operation and maintaining a clean working environment. When the bagged cement is weighed and needs to be returned to the cement conveyor belt 2, the weighing conveyor 6 is moved above the cement conveyor belt 2. At this time, the weighing gripper 606 is opened. During the opening of the weighing gripper 606, the piston rod of the weighing drive hydraulic cylinder 603 moves upward. The movement of the weighing protective connecting rod 608 causes the weighing protective connecting rod 608 to move upward, which in turn causes the weighing drive rack 609 to move upward, which in turn causes the weighing drive gear 611 to rotate, which in turn causes the weighing extrusion rack 612 to move downward, which in turn causes the weighing extrusion plate 615 to move downward, which in turn causes the weighing extrusion plate 615 to move downward, thus extruding the bagged cement and facilitating the subsequent stacking of the bagged cement.
