[0017] 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.

[0018] This utility model provides, for example Figures 1-5 The weighing conveying mechanism shown includes a support frame 1 and a conveying mechanism 2 mounted on the support frame 1. The conveying mechanism 2 includes a feeding conveyor 21, a weighing conveyor 22, and a discharging conveyor 23, which are installed sequentially from left to right on the support frame 1. A support plate 3 is installed at the bottom of the weighing conveyor 22. A weighing sensor 4 for weighing materials is installed on the support frame 1 at a position corresponding to the support plate 3. The surface of the weighing sensor 4 is connected to the lower surface of the support plate 3. Adjustable feeding and receiving devices are installed at both ends of the support frame 1. The section mechanism 5 has a support rod 6 fixedly connected to the center of one side of the support frame 1. One end of the support rod 6 is fixedly connected to a controller 7. The designed conveying mechanism 2 can provide material conveying function. A support plate 3 is installed at the position of the weighing conveyor 22 in the conveying mechanism 2. The support plate 3 is connected to the weighing sensor 4 on the support frame 1. Therefore, the material can be weighed when it passes the position of the weighing conveyor 22, which further enhances the accuracy of material weight weighing. The adjustment mechanism 5 can realize the effect of automatic material receiving and feeding, which improves the working efficiency of the weighing conveying mechanism of the weighing machine.

[0019] Material baffles 8 are installed at symmetrical positions on the top of the feeding conveyor 21, weighing conveyor 22, and discharging conveyor 23. A pusher assembly 9 is installed on one side of the material baffle 8 at the position of the discharging conveyor 23, and a guide port is opened on the other side of the material baffle 8. The guide port is fixedly connected to the discharge chute 10. The material baffles 8 can block the materials conveyed on the feeding conveyor 21, weighing conveyor 22, and discharging conveyor 23. Then, the pusher assembly 9 can remove unqualified materials from the guide port, avoiding the mixing of unqualified materials with qualified materials and saving the time of the staff in sorting.

[0020] The adjustment mechanism 5 includes a fixed frame 51, which is installed at both ends of the support frame 1. The upper ends of the two fixed frames 51 are flush with the feeding conveyor 21 and the discharging conveyor 23, respectively. A hydraulic cylinder 52 is fixedly connected to the bottom of the inner cavity of the fixed frame 51. The piston rod of the hydraulic cylinder 52 is fixedly connected to a placement plate 53. Sliding components 54 are provided between the two sides of the placement plate 53 and the fixed frame 51. By setting the fixed frame 51, the hydraulic cylinder 52 can be easily installed, thereby driving the placement plate 53 to be raised and lowered inside the fixed frame 51. This allows for the receiving and feeding of materials, as well as the stacking of materials, ensuring the neatness of the materials and facilitating the organization by the staff.

[0021] The sliding assembly 54 includes a slide groove 541, which is formed on two symmetrical sides of the fixed frame 51. A positioning rod 542 is fixedly connected in the slide groove 541. A limit block 543 is slidably connected to the positioning rod 542 through a sliding sleeve. One side of the limit block 543 is fixedly connected to both ends of the placement plate 53. Through the cooperation of the slide groove 541, the positioning rod 542 and the limit block 543, the position of the placement plate 53 is limited, thereby enhancing the stability of the lifting and moving of the placement plate 53.

[0022] The pushing assembly 9 includes a pushing cylinder 91, which is installed on a baffle plate 8 at a position symmetrical to the guide chute. The piston rod of the pushing cylinder 91 passes through the baffle plate 8 and is fixedly connected to a push plate 92. The length of the push plate 92 is equal to the diameter of the guide opening. The pushing cylinder 91 provides driving force to drive the push plate 92 to push the material that does not meet the weight requirements on the discharge conveyor 23. Subsequently, the material that does not meet the weight requirements is discharged through the discharge chute 10.

[0023] Limiting rods 93 are movably connected to the baffle plates 8 located on both sides of the pusher cylinder 91. One end of the limiting rod 93 is fixedly connected to one side of the pusher plate 92, and the other end of the limiting rod 93 is fixedly connected to a locking block 94. The cooperation between the limiting rod 93 and the locking block 94 enhances the stability of the pusher plate 92 when it moves.

[0024] The controller 7 is electrically connected to the weighing sensor 4 and the conveying mechanism 2. The controller 7 can conveniently control the operation of the weighing sensor 4 and the conveying mechanism 2, thereby enabling the weighing and conveying of materials.

[0025] In practical use, the material is fed through the adjustment mechanism 5 at one end of the feeding conveyor 21, and then conveyed to the position of the weighing conveyor 22 by the feeding conveyor 21. Subsequently, the material is weighed by the weighing sensor 4, and then the material is output through the discharge conveyor 23. During the discharge process, materials that do not meet the weight requirements can be removed from the guide port by the pushing component 9, which avoids the mixing of materials with qualified materials and saves the time of the staff. Then the discharged material is received by the adjustment mechanism 5 at one end of the discharge conveyor 23. During the receiving process, the hydraulic cylinder 52 drives the placement plate 53 to descend, and then the materials can be stacked, which is convenient for the staff to handle the materials.
