Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, and in particular to a stable feeding structure for a casting feeder. Background Technology

[0002] The casting charging machine, also known as the electric furnace charging car, is used in the modern sand casting field to pour a large amount of metallurgy into the sand mold. The casting charging car is a device that transports raw materials into the electric furnace cavity during the electric furnace metallurgical process. Existing charging cars use a vibrating motor as the excitation source when unloading, so that the raw materials slide from the front end of the discharge chute into the electric furnace cavity with the vibration of the discharge chute.

[0003] CN 210619356 U discloses a charging car for an electric furnace, including a feeding trolley and a vibrating conveyor mounted on the feeding trolley. Rollers are arranged on opposite sides of the bottom surface of the feeding trolley, and a drive component is provided on the feeding trolley to drive the rollers. The vibrating conveyor is connected inside the feeding trolley via a vibrating spring. A discharge hopper is connected to the discharge end of the vibrating conveyor. The feeding trolley is equipped with a conveying track, and a limiting mechanism for stopping the trolley is provided on the top surface of the end of the conveying track away from the feeding trolley. When the limiting mechanism is in the retracted position, the discharge hopper is close to the furnace inlet. This charging car effectively reduces the feeding deviation of the feeding trolley when stopping at the furnace inlet, thus improving the feeding efficiency into the furnace.

[0004] However, when the aforementioned feeding vehicle is transporting materials, if the material in the hopper is too full, the materials are prone to jamming each other, resulting in uneven material transport. Furthermore, during the process of pouring the material into the electric furnace, the material lacks guidance after leaving the hopper and falls freely under the influence of gravity, causing some material to be poured out of the furnace opening. This requires manual pushing of the material outside the furnace opening into the furnace, which brings inconvenience to the feeding operation. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the prior art, this utility model provides a stable feeding structure for a casting feeder.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a stable feeding structure for a casting feeder, including a vibrating conveyor, a storage box at the rear end of the vibrating conveyor, a discharge hopper connected to the front end of the storage box, a baffle assembly at the connection between the storage box and the discharge hopper, the baffle assembly including a baffle plate, the baffle plate being liftably mounted on the vibrating conveyor, a fixed frame fixedly mounted at the discharge end of the discharge hopper, a dropping box movably mounted on the fixed frame, a guide cylinder fixedly mounted inside the dropping box, and a first hydraulic cylinder mounted on the fixed frame for driving the dropping box to move.

[0007] Furthermore, the fixing frame has a C-shaped structure, and two sets of sliding blocks are fixedly installed on the inner front wall of the fixing frame. Guide rails are slidably installed on the sliding blocks, and the guide rails are fixedly installed on the material drop box. The guide rails extend along the height direction of the material drop box. The first hydraulic cylinder is fixedly installed on the outer front wall of the fixing frame, and a connecting plate is fixedly installed on the power output end of the first hydraulic cylinder. The connecting plate is fixedly installed on the material drop box.

[0008] Furthermore, the material discharge box has a rectangular cylindrical structure, and a material inlet is provided at the top of the side wall of the material discharge box near the discharge hopper. The material guide cylinder is fixedly installed on the inner wall of the material discharge box, and the material guide cylinder has a top-to-bottom structure.

[0009] Furthermore, the baffle assembly also includes two sets of guide rods, which are vertically arranged on the left and right sides of the vibrating conveyor. A fixed seat is fixedly installed at the bottom end of each guide rod, and the fixed seat is fixedly installed on the side wall of the vibrating conveyor. A connecting seat is slidably installed on each set of guide rods, and the two sets of connecting seats are fixedly installed on the left and right sides of the baffle plate. A fixed plate is fixedly installed at the top end of each set of guide rods, and a second hydraulic cylinder is fixedly installed on the fixed plate. The power output end of the second hydraulic cylinder is fixedly connected to the baffle plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. The design of this utility model is to install a baffle plate at the connection between the storage box and the discharge hopper. By adjusting the size of the opening between the baffle plate and the bottom plate of the storage box, the discharge amount can be controlled, thereby avoiding the situation where the material in the discharge hopper is too full, and thus preventing the material from getting stuck in the discharge hopper, so as to ensure the stability of feeding.

[0012] 2. The design of this utility model features a fixed frame installed at the discharge end of the hopper, with a movable dropping box mounted on the frame. When the vibrating conveyor moves toward the electric furnace, the dropping box blocks the material in the hopper. After the vibrating conveyor reaches its position, the first hydraulic cylinder drives the dropping box to descend, causing the bottom of the guide cylinder to insert into the furnace opening. At this time, the material in the hopper enters the dropping box and, guided by the guide cylinder, enters the electric furnace, thus preventing the material from being dumped outside the furnace opening and improving the convenience of the feeding operation.

[0018] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0019] according to Figure 1-3 As shown, a stable feeding structure for a casting feeder includes a vibrating conveyor 1. A storage box 101 is provided at the rear end of the vibrating conveyor 1, and a discharge hopper 102 is connected to the front end of the storage box 101. A baffle assembly is provided at the connection between the storage box 101 and the discharge hopper 102. The baffle assembly includes a baffle plate 2, which is movably mounted on the vibrating conveyor 1. A fixed frame 3 is fixedly installed at the discharge end of the discharge hopper 102. A drop box 4 is movably mounted on the fixed frame 3. A guide cylinder 5 is fixedly installed on the inner side of the drop box 4. A first hydraulic cylinder 6 is installed on the fixed frame 3. The first hydraulic cylinder 6 is used to drive the drop box 4 to move.

[0020] In this embodiment, the fixing frame 3 has a C-shaped structure. Two sets of sliding blocks 7 are fixedly installed on the inner front wall of the fixing frame 3. Guide rails 8 are slidably installed on the sliding blocks 7. The guide rails 8 are fixedly installed on the material drop box 4 and extend along the height direction of the material drop box 4. The first hydraulic cylinder 6 is fixedly installed on the outer front wall of the fixing frame 3. A connecting plate 9 is fixedly installed on the power output end of the first hydraulic cylinder 6. The connecting plate 9 is fixedly installed on the material drop box 4. Preferably, the first hydraulic cylinder 6 is a multi-stage hydraulic cylinder. The material drop box 4 has a rectangular cylindrical structure. A feed inlet 401 is opened at the top of the side wall of the material drop box 4 near the discharge hopper 102. The guide cylinder 5 is welded to the inner wall of the discharge box 4. The guide cylinder 5 has a top-to-bottom structure and is located below the feed inlet 401. When the vibrating conveyor 1 moves toward the electric furnace, the first hydraulic cylinder 6 drives the discharge box 4 to rise to the limit position, blocking the material in the dump hopper 102 through the side wall of the discharge box 4. After the vibrating conveyor 1 moves into position, the first hydraulic cylinder 6 drives the discharge box 4 to fall to the limit position, so that the guide cylinder 5 is inserted into the furnace opening. At this time, the feed inlet 401 is flush with the bottom wall of the dump hopper 102, and the material in the dump hopper 102 enters the guide cylinder 5 through the feed inlet 401.

[0021] In this embodiment, the baffle assembly also includes two sets of guide rods 10, which are vertically arranged on the left and right sides of the vibrating conveyor 1. A fixed seat 11 is fixedly installed at the bottom end of the guide rod 10, and the fixed seat 11 is fixedly installed on the side wall of the vibrating conveyor 1 by bolts. A connecting seat 12 is slidably installed on each set of guide rods 10, and the two sets of connecting seats 12 are fixedly installed on the left and right sides of the baffle plate 2. A fixed plate 13 is fixedly installed at the top end of the two sets of guide rods 10, and a second hydraulic cylinder 14 is fixedly installed on the fixed plate 13. The power output end of the second hydraulic cylinder 14 is fixedly connected to the baffle plate 2. The second hydraulic cylinder 14 drives the baffle plate 2 to rise or fall along the guide rods 10, thereby adjusting the opening size between the baffle plate 2 and the bottom plate of the storage box 101, thereby controlling the discharge amount and avoiding the situation where the material in the dump hopper 102 is too full.

[0022] In use, the vibrating conveyor 1 is mounted on a railcar (not shown in the figure). Material is piled in the storage bin 101. The railcar transports the vibrating conveyor 1 to the electric furnace. As the vibrating conveyor 1 moves towards the furnace, the first hydraulic cylinder 6 drives the discharge bin 4 to rise to its limit position. The side wall of the discharge bin 4 blocks the material in the discharge hopper 102. After the vibrating conveyor 1 reaches its position, the first hydraulic cylinder 6 drives the discharge bin 4 to descend to its limit position, allowing the guide cylinder 5 to insert into the furnace opening. This prevents material from being spilled outside the furnace opening, improving the convenience of the feeding process. Then, the second hydraulic cylinder 14 drives the baffle plate 2 to rise, and at the same time, the vibrating conveyor 1 vibrates under the action of the vibrating motor, so that the material enters the discharge hopper 102 from the storage box 101, enters the dropping box 4 through the discharge hopper 102, and enters the electric furnace under the guidance of the guide cylinder 6. During the process of adding material into the furnace, the operator adjusts the size of the opening between the baffle plate 2 and the bottom plate of the storage box 101 according to the amount of material in the discharge hopper 102, so as to control the discharge amount, thereby avoiding the situation that the material in the discharge hopper 102 is too full, and thus preventing the material from getting stuck in the discharge hopper 102, so as to ensure the stability of feeding.

[0023] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
