Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, specifically to a feeding and conveying device for metal calcium rod raw materials. Background Technology

[0002] Calcium metal rods are an important industrial raw material, widely used in calcium alloy smelting, metal thermal reduction, and steel deoxidation and desulfurization. During the production and processing of calcium metal rods, the rod-shaped raw materials need to be transported one by one from the storage area to the next processing station, such as extrusion, cutting, or packaging. Because the raw material is cylindrical, dust and impurities easily adhere to its surface, and the rods are prone to collision damage, high requirements are placed on the conveying device's conveying method, surface cleaning ability, and rod-by-rod distribution capability. Currently, most existing rod-shaped raw material feeding and conveying devices use inclined slides combined with a baffle mechanism to achieve automatic material conveying. However, in actual use, the following shortcomings still exist: First, dust and impurities adhering to the surface of the raw materials during the conveying process cannot be effectively cleaned. These impurities, after entering subsequent processing steps, will affect product quality and even cause additional wear to the processing equipment. Second, in the existing rod-by-rod feeding mechanism, there is frictional contact between the lifting components and the raw materials in the waiting area during the lifting process, which can easily cause scratches on the surface of the raw materials to be conveyed. At the same time, the frictional resistance will also affect the stability of the lifting components. Third, when the raw materials are lifted to the end of the conveying process, there is a lack of effective auxiliary pushing means. When the raw materials are close to the top, they are prone to jamming due to insufficient gravity or excessive friction, resulting in conveying interruption and affecting production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a feeding and conveying device for calcium metal rods to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a raw material feeding and conveying device for calcium metal rods, comprising a raw material conveying bed, the raw material conveying bed being inclined in the feeding direction, an elevated frame being provided at the output end of the raw material conveying bed, cabinets being provided on both sides of the elevated frame, the top of the elevated frame being inclined in the same direction as the inclined direction of the raw material conveying bed, and two baffles being provided on both sides of the top of the elevated frame, characterized in that it further comprises an automatic conveying mechanism, a surface cleaning mechanism, and an interval feeding mechanism; The automatic conveying mechanism includes a lifting frame, a lifting cylinder, and a pushing assembly. The lifting frame is vertically and flexibly mounted on the side of the elevated frame near the raw material conveying bed. The lifting cylinder is used to drive the lifting frame to rise and fall. The pushing assembly is mounted on the side of the elevated frame away from the raw material conveying bed and is used to push the raw material that has reached the top of the elevated frame to the next work station. The surface cleaning mechanism includes a cleaning brush assembly disposed at the top of the lifting frame, which rotates and cleans the surface of the raw material during the lifting and lowering process of the lifting frame; The interval feeding mechanism includes a blocking component and a linkage component. The blocking component is located at one end of the raw material conveying bed near the elevated frame. It is used to block and release the raw material on the raw material conveying bed and to straighten the raw material before it enters the top of the lifting frame. One end of the linkage component is connected to the lifting frame, and the other end is connected to the blocking component for transmission, so that the blocking component switches between blocking and releasing states as the lifting frame rises and falls.

[0005] Preferably, the automatic conveying mechanism further includes limiting grooves and guide frames. There are two limiting grooves, which are fixedly installed at both ends of the elevated frame near the raw material conveying bed and located on both sides of the raw material conveying bed. The lifting frame is slidably installed between the two limiting grooves. The guide frame is fixedly installed inside the lifting frame. The lifting cylinder is located between the two limiting grooves and at the middle of the bottom end. The output shaft of the lifting cylinder extends into the lifting frame and is fixedly connected to the guide frame.

[0006] Preferably, the pushing assembly includes a bracket, an arc-shaped groove, and a pushing cylinder. The bracket is fixedly installed at the top of the two cabinets and is located on the side of the overhead frame away from the raw material conveying bed. The arc-shaped groove is fixedly installed at the top of the bracket. The pushing cylinder is fixedly installed at the top of the bracket, and its output shaft is close to the overhead frame. The end of the arc-shaped groove near the pushing cylinder extends beyond the side of the overhead frame away from the raw material conveying bed. The output shaft of the pushing cylinder can extend beyond the distance between the two sides of the top of the overhead frame.

[0007] Preferably, the cleaning brush assembly includes a lifting roller brush, a lifting groove, a lifting gear, a fixed rack, and a synchronous belt. There are two lifting roller brushes, both rotatably mounted inside the top of the lifting frame. A groove for receiving raw materials is formed between the two lifting roller brushes. There are two lifting grooves, both opened on a limiting groove on the right side. The right ends of the two lifting roller brushes pass through the lifting frame and extend out of the two lifting grooves respectively. The lifting gear is fixedly sleeved on the right end of the lifting roller brush near the raw material conveying bed. The fixed rack is fixedly mounted on the right side of the limiting groove on the right side. The lifting gear and the fixed rack are meshed and connected. The two ends of the synchronous belt are respectively sleeved on the right ends of the two lifting roller brushes, so that the two lifting roller brushes rotate synchronously.

[0008] Preferably, the cleaning brush assembly further includes an inclined groove, a connecting seat, an inclined roller brush, connecting rods, and springs. The inclined groove is formed at the top of the side wall of the two limiting grooves. The lower end of the inclined groove is close to the raw material conveying bed, and the upper end is located at the middle of the top of the side wall of the limiting groove, close to the raw material conveying bed. There are two connecting seats, which are slidably installed in the two inclined grooves respectively. The inclined roller brush is rotatably installed between the two connecting seats. There are two connecting rods, which are fixedly installed at the top of the outer side wall of the two limiting grooves respectively. The two connecting rods are located on the outside of the two inclined grooves and are in the same direction as the inclined grooves. The two connecting seats are slidably sleeved on the connecting rods on the corresponding sides respectively. There are two springs, which are sleeved on the two connecting rods respectively. One end of the spring abuts against the connecting seat, and the other end abuts against the end of the connecting rod, for providing a restoring thrust after the inclined roller brush is squeezed open by the raw material.

[0009] Preferably, the linkage component of the interval feeding mechanism includes a connecting arm and a movable rack, and the blocking component includes a rotating shaft, a rotating arm, and an incomplete gear. The rotating shaft is rotatably mounted on one end of the raw material conveying bed near the elevated frame. The middle part of the rotating arm is fixedly sleeved on the rotating shaft, and the incomplete gear is fixedly sleeved on the rotating shaft. The connecting arm is located on the side of the raw material conveying bed, and the lower end of the connecting arm is movably sleeved on a lifting roller brush near the raw material conveying bed and fixedly connected to the top of the side wall of the lifting frame. The movable rack is fixedly mounted on the upper end of the connecting arm and located on the side near the raw material conveying bed. The movable rack engages with or disengages from the incomplete gear when the lifting frame rises and falls.

[0010] Preferably, the blocking assembly further includes a rotating groove, a lower blocking cylinder, and an upper blocking cylinder. The rotating groove is located at one end of the raw material conveying bed near the overhead frame. The lower blocking cylinder is movably disposed within the rotating groove, and its right end is movably connected to the lower end of the rotating arm. The right end of the upper blocking cylinder is movably connected to the upper end of the rotating arm. The lower blocking cylinder is a hollow cylinder structure, and the upper blocking cylinder is a solid cylinder structure. The mass of the upper blocking cylinder is greater than that of the lower blocking cylinder, so that after the movable rack disengages from the incomplete gear, the rotating arm automatically resets under the gravity of the upper blocking cylinder. Both the lower and upper blocking cylinders are arranged parallel to the two lifting rollers, so that the raw material entering between the lower and upper blocking cylinders is aligned parallel to the lifting rollers.

[0011] Preferably, the interval feeding mechanism further includes an L-plate and a spring sheet. The L-plate is fixedly installed on the side wall of the raw material conveying bed and located above the rotating shaft. The spring sheet is fixedly installed on the side of the L-plate near the rotating arm. The spring sheet is compressed when the rotating arm rotates to a near-vertical state, and the rotating arm is reset by elastic force.

[0012] Preferably, the groove formed between the two lifting rollers is used to accommodate the raw material when it reaches the top of the lifting frame, thus preventing the raw material from directly colliding with the side wall of the elevated structure.

[0013] Preferably, the guide frame is inclined to guide the impurities swept down by the lifting roller brush to be discharged from the lifting frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes the meshing of the lifting gear and the fixed rack during the lifting of the material frame to drive the lifting roller brush to rotate. This allows the surface dust and impurities of the raw material to be cleaned during the lifting process, eliminating the need for a separate cleaning process or power source. This achieves synchronous surface cleaning during the conveying process. Furthermore, the angled roller brush allows for secondary cleaning of the raw material as it approaches the top of the overhead frame, further enhancing the cleaning effect and ensuring that the surface of the raw material is clean before entering the next processing step. This is beneficial for improving the quality of the final product and reducing wear on subsequent equipment.

[0015] 2. This invention utilizes the intermittent meshing of a movable rack and an incomplete gear, combined with the alternating movements of the upper and lower blocking cylinders, to ensure that during the lifting and unloading process of the lifting frame, the next piece of material to be conveyed is always limited and isolated by the lower blocking cylinder, preventing contact with the rising lifting frame. This avoids frictional scratches on the surface of the material to be conveyed during the lifting frame's ascent, ensuring the integrity of the material surface. Simultaneously, the lower blocking cylinder effectively separates the second and third pieces of material, preventing multiple pieces of material from entering the conveying channel simultaneously and causing jamming. Furthermore, both the lower and upper blocking cylinders are arranged parallel to the two lifting rollers, automatically aligning the material entering between the two blocking cylinders to be parallel to the lifting rollers. This ensures that both ends of the material enter the groove between the lifting rollers synchronously, preventing collisions with the elevated sidewalls due to material deviation during the lifting process.

[0016] 3. This invention has an anti-jamming function and high conveying reliability. By setting an inclined roller brush, after the raw material is squeezed out at the top of the overhead conveyor, it relies on the spring force to reset. During the reset process, a pushing force is applied to the raw material towards the top of the overhead conveyor, which helps the raw material to smoothly transition to the top of the overhead conveyor. This effectively solves the problem of material jamming at the end of the conveyor due to insufficient gravity or excessive friction, and improves the continuity and reliability of the conveying.

[0017] 4. In this invention, the lifting and lowering movement of the lifting frame is driven synchronously by the transmission of the connecting arm, the movable rack and the incomplete gear, which drives the intermittent feeding mechanism. At the same time, the surface cleaning mechanism is driven synchronously by the meshing of the lifting gear and the fixed rack. The three major functions of the entire device—lifting and conveying, surface cleaning and intermittent feeding—are all driven by the lifting cylinder as a single driving source. There is no need to configure a separate power source for each functional module. The transmission chain is simple, the structure is compact, and the synchronization is good.

[0018] 5. In this invention, the upper blocking cylinder has a greater mass than the lower blocking cylinder. After the incomplete gear disengagement restriction, the upper blocking cylinder can drive the rotating arm to reset by its own weight, so that the lower blocking cylinder automatically returns to the blocking position. There is no need to set up an additional reset spring or drive device. The structure is simple and the operation is reliable. At the same time, the setting of the spring plate provides an auxiliary reset force for the rotating arm, which further ensures the stability of the reset action. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This embodiment provides a feeding and conveying device for raw materials of calcium metal rods, such as... Figures 1 to 8 As shown, it includes a raw material conveying bed 1, which is inclined in the feeding direction. A high frame 2 is provided at the output end of the raw material conveying bed 1. Cabinets 3 are provided on both sides of the high frame 2. The top of the high frame 2 is inclined in the same direction as the inclination of the raw material conveying bed 1. There are two baffles 4, which are respectively provided on both sides of the top of the high frame 2 to prevent the raw materials from rolling off the sides of the high frame 2.

[0023] By tilting the raw material conveying bed 1 in the feeding direction, the material is automatically conveyed using its own gravity, allowing the columnar calcium metal rod material to automatically roll towards the elevated frame 2. The elevated frame 2 is used to receive the lifted material and uses its top inclined surface to allow the material to continue rolling naturally towards the next work station, achieving a smooth connection of the conveying path. The cabinet 3 provides a stable structural support foundation for the entire device. The baffle 4 laterally limits the material that rolls to the top of the elevated frame 2, preventing the material from rolling off the sides during the tilting and rolling process, playing a dual role of guidance and protection, ensuring that the material is always safely and orderly conveyed to the next work station along the predetermined path.

[0024] At other levels, this embodiment also provides an automatic conveying mechanism 5, such as... Figures 1 to 7 As shown, the automatic conveying mechanism 5 includes a limiting groove 501, a lifting frame 502, a guide frame 503, a lifting cylinder 504, and a pushing assembly.

[0025] In this embodiment, as Figures 1 to 5 As shown, there are two limiting grooves 501, which are fixedly installed at both ends of the elevated frame 2 near the raw material conveying bed 1, and are located on both sides of the raw material conveying bed 1. The lifting frame 502 is slidably installed between the two limiting grooves 501 and can slide up and down along the limiting grooves 501. The guide frame 503 is fixedly installed inside the lifting frame 502 and is inclined to guide the impurities swept down by the lifting roller brush 601 to be discharged from the lifting frame 502. The lifting cylinder 504 is located between the two limiting grooves 501 and at the middle of the bottom end. The output shaft of the lifting cylinder 504 extends into the lifting frame 502 and is fixedly connected to the guide frame 503.

[0026] By extending and retracting the output shaft of the lifting cylinder 504, the lifting frame 502 is driven up and down along the limiting groove 501 via the guide frame 503, thereby lifting the raw material located at the top of the lifting frame 502 from the lower end of the raw material conveying bed 1 to the top of the elevated frame 2.

[0027] In this embodiment, as Figures 1 to 3 As shown, the feeding assembly includes a bracket 505, an arc-shaped groove 506, and a feeding cylinder 507. The bracket 505 is fixedly installed on the top of the two cabinets 3 and is located on the side of the elevated frame 2 away from the raw material conveying bed 1. The arc-shaped groove 506 is fixedly installed on the top of the bracket 505 and is used to receive raw materials rolling down from the top of the elevated frame 2. The feeding cylinder 507 is fixedly installed on the top of the bracket 505, and its output shaft is close to the elevated frame 2. The end of the arc-shaped groove 506 near the feeding cylinder 507 extends beyond the side of the elevated frame 2 away from the raw material conveying bed 1, and the output shaft of the feeding cylinder 507 can extend beyond the distance between the two sides of the top of the elevated frame 2.

[0028] By extending the output shaft of the pusher cylinder 507, the raw material in the arc-shaped groove 506 is pushed to the next processing area, thereby realizing the automatic discharge of the raw material.

[0029] At other levels, this embodiment also provides a surface cleaning mechanism 6, such as... Figures 4 to 7 As shown, the surface cleaning mechanism 6 includes a cleaning brush assembly, which includes a lifting roller brush 601, a lifting groove 602, a lifting gear 603, a fixed rack 604, and a timing belt 605.

[0030] In this embodiment, as Figures 4 to 7 As shown, there are two lifting roller brushes 601, both rotatably mounted inside the top of the lifting frame 502. A groove for accommodating raw materials is formed between the two lifting roller brushes 601, used to accommodate the raw materials when they reach the top of the lifting frame 502, preventing direct collision with the side wall of the elevated frame 2. There are two lifting slots 602, both located on a limiting slot 501 on the right side. The right ends of the two lifting roller brushes 601 pass through the lifting frame 502 and extend out of the two lifting slots 602 respectively. A lifting gear 603 is fixedly sleeved on the right end of one of the lifting roller brushes 601 near the raw material conveying bed 1. A fixed rack 604 is fixedly mounted on the right side of the limiting slot 501 on the right side, and the lifting gear 603 meshes with the fixed rack 604. The two ends of a synchronous belt 605 are respectively sleeved on the right ends of the two lifting roller brushes 601, causing the two lifting roller brushes 601 to rotate synchronously.

[0031] When the material is lifted by the lifting frame 502, the lifting gear 603 rolls on the fixed rack 604, thereby driving the connected lifting roller brush 601 to rotate. At the same time, the synchronous belt 605 drives another lifting roller brush 601 to rotate synchronously. The two lifting roller brushes 601 together drive the raw material in the groove above them to rotate, thereby achieving rotational cleaning of the raw material surface.

[0032] In this embodiment, as Figure 4 and Figure 5 As shown, the cleaning brush assembly also includes an inclined groove 606, a connecting seat 607, an inclined roller brush 608, a connecting rod 609, and a spring 610. The inclined groove 606 is formed at the top of the side wall of the two limiting grooves 501. The lower end of the inclined groove 606 is close to the raw material conveying bed 1, and the upper end is located at the middle of the top of the side wall of the limiting groove 501, close to the raw material conveying bed 1. There are two connecting seats 607, which are slidably installed in the two inclined grooves 606 respectively. The inclined roller brush 608 is rotatably installed between the two connecting seats 607. There are two connecting rods 609, which are fixedly installed at the top of the outer side wall of the two limiting grooves 501 respectively. The two connecting rods 609 are located outside the two inclined grooves 606 and in the same direction as the inclined grooves 606. The two connecting seats 607 are slidably sleeved on the corresponding connecting rods 609. There are two springs 610, which are respectively sleeved on the two connecting rods 609. One end of the spring 610 abuts against the connecting seat 607, and the other end abuts against the end of the connecting rod 609.

[0033] When the material approaches the top of the overhead frame 2, the inclined roller brush 608 performs a secondary cleaning. After the material rises and pushes the inclined roller brush 608 away, the connecting seat 607 slides along the inclined groove 606 and the connecting rod 609 and compresses the spring 610. After the material is removed, the spring 610 pushes the inclined roller brush 608 to reset. During the reset process, a pushing force is applied to the material towards the top of the overhead frame 2 to help the material smoothly transition to the top of the overhead frame 2 and prevent jamming.

[0034] At other levels, this embodiment also provides an interval feeding mechanism 7, such as... Figures 5 to 8 As shown, the interval feeding mechanism 7 includes a blocking component and a linkage component. The blocking component is located at one end of the raw material conveying bed 1 near the elevated frame 2 and is used to block and release the raw materials on the raw material conveying bed 1. One end of the linkage component is connected to the lifting frame 502, and the other end is connected to the blocking component for transmission.

[0035] In this embodiment, as Figures 5 to 8 As shown, the linkage assembly includes a connecting arm 704 and a movable rack 705, and the blocking assembly includes a rotating shaft 701, a rotating arm 702, and an incomplete gear 703. The rotating shaft 701 is rotatably mounted on one end of the raw material conveying bed 1 near the overhead frame 2. The middle part of the rotating arm 702 is fixedly sleeved on the rotating shaft 701, and the incomplete gear 703 is fixedly sleeved on the rotating shaft 701. The connecting arm 704 is located on the side of the raw material conveying bed 1. The lower end of the connecting arm 704 is movably sleeved on a lifting roller brush 601 near the raw material conveying bed 1 and is fixedly connected to the top of the side wall of the lifting frame 502. The movable rack 705 is fixedly mounted on the upper end of the connecting arm 704 and is located on the side near the raw material conveying bed 1.

[0036] The lifting motion of the lifting frame 502 drives the connecting arm 704 and the movable rack 705 to lift synchronously. During the lifting process, the movable rack 705 intermittently meshes with the incomplete gear 703, thereby driving the rotating shaft 701 and the rotating arm 702 to rotate, so that the blocking component automatically switches between the blocking state and the releasing state as the lifting frame 502 lifts.

[0037] In this embodiment, as Figures 5 to 8 As shown, the blocking assembly also includes a rotating groove 706, a lower blocking cylinder 707, and an upper blocking cylinder 708. The rotating groove 706 is located at one end of the raw material conveying bed 1 near the overhead frame 2. The lower blocking cylinder 707 is movably disposed within the rotating groove 706, and its right end is movably connected to the lower end of the rotating arm 702. The right end of the upper blocking cylinder 708 is movably connected to the upper end of the rotating arm 702. The lower blocking cylinder 707 is a hollow cylinder, while the upper blocking cylinder 708 is a solid cylinder. The upper blocking cylinder 708 has a greater mass than the lower blocking cylinder 707. The lower blocking cylinder 707, the upper blocking cylinder 708, and the two lifting roller brushes 601 are parallel to each other.

[0038] The rotation of the rotating arm 702 causes the upper blocking cylinder 708 and the lower blocking cylinder 707 to move alternately: when the lifting frame 502 rises, the lower blocking cylinder 707 descends to release the first raw material, and the upper blocking cylinder 708 rises to block subsequent raw materials. After the first raw material enters the lifting frame 502, the lower blocking cylinder 707 resets to isolate the second raw material, preventing it from contacting and rubbing against the rising lifting frame 502. When the lifting frame 502 descends, the movable rack 705 meshes with the incomplete gear 703 again, causing the lower blocking cylinder 707 to descend and release the second raw material, thus achieving intermittent feeding.

[0039] As the raw material enters between the lower blocking cylinder 707 and the upper blocking cylinder 708, the upper blocking cylinder 708 rotates and resets due to its own weight. In addition, since the lower blocking cylinder 707, the upper blocking cylinder 708 and the two lifting rollers 601 are parallel, the raw material entering between the lower blocking cylinder 707 and the upper blocking cylinder 708 is aligned and parallel to the two lifting rollers 601. This prevents the two ends of the raw material from entering between the two lifting rollers 601 at different times, and avoids collision between the raw material and the overhead frame 2 due to the rotation of the lifting rollers 601 during the ascent.

[0040] In this embodiment, as Figures 5 to 8As shown, the interval feeding mechanism 7 also includes an L-plate 709 and a spring plate 710. The L-plate 709 is fixedly installed on the side wall of the raw material conveying bed 1 and is located above the rotating shaft 701. The spring plate 710 is fixedly installed on the side of the L-plate 709 near the rotating arm 702. The spring plate 710 is compressed when the rotating arm 702 rotates to a near-vertical state, and the elastic force assists the rotating arm 702 in resetting, ensuring the stability of the upper blocking cylinder 708 when resetting by gravity, and avoiding incomplete resetting due to friction or other factors.

[0041] Working principle: When using this invention, the raw material of metal calcium rod is placed on the raw material conveying bed 1. Since the raw material conveying bed 1 is inclined, the columnar raw material automatically rolls towards the elevated frame 2. Since the mass of the upper blocking cylinder 708 is greater than that of the lower blocking cylinder 707, the lower blocking cylinder 707 is located at the end of the rotating groove 706 away from the elevated frame 2, that is, inside the raw material conveying bed 1. Therefore, the first raw material is blocked by the lower blocking cylinder 707. When the lifting cylinder 504 is activated, its output shaft rises, which in turn drives the lifting frame 502 to rise via the guide frame 503. This causes the connecting arm 704 to rise simultaneously, and the connecting arm 704 drives the movable rack 705 to rise. As the movable rack 705 rises, it drives the rotating shaft 701 to rotate via the incomplete gear 703, causing the rotating arm 702 to rotate. This causes the upper blocking cylinder 708 to rotate away from the elevated frame 2, and the lower blocking cylinder 707 to rotate closer to the elevated frame 2. At this time, the lower blocking cylinder 707 descends towards the bottom of the raw material conveying bed 1, allowing the first raw material blocked by the lower blocking cylinder 707 to pass between the lower blocking cylinder 707 and the upper blocking cylinder 708 and enter between the two limiting grooves 501, landing on the top of the lifting frame 502. Because there is a groove between the two lifting rollers 601 at the top of the lifting frame 502, the raw material stays there, preventing it from directly colliding with the side wall of the elevated frame 2. The raw material entering between the lower blocking cylinder 707 and the upper blocking cylinder 708 is straightened. As the first raw material falls into the rising lifting frame 502, the second raw material enters between the lower blocking cylinder 707 and the upper blocking cylinder 708. When the movable rack 705 leaves the incomplete gear 703, the incomplete gear 703 is released from its meshing restriction. Under the gravity of the upper blocking cylinder 708, the lower blocking cylinder 707 re-enters the raw material conveying bed 1, thus limiting the second raw material. The lower blocking cylinder 707 separates the second raw material from the third raw material, preventing the second raw material from contacting the rising lifting frame 502 and avoiding friction from the rising lifting frame 502. When the first raw material rises, the lifting frame 502 drives the lifting gear 603 to rise. At this time, the fixed rack 604 causes the rising lifting gear 603 to rotate, and the synchronous belt 605 causes the two lifting rollers 601 to rotate in the same direction at the same time, which in turn drives the raw material above to rotate, so as to clean the dust and other impurities on the surface of the raw material. The swept impurities enter the lifting frame 502 and fall down through the guide frame 503. When the raw material rises to near the top of the overhead frame 2, the top of the raw material first contacts the inclined roller brush 608, while the lifting frame 502 continues to move upward. At this time, the raw material pushes the inclined roller brush 608 away, so that the inclined roller brush 608 moves downward along the direction of the inclined groove 606 and the connecting rod 609 through the connecting seat 607. During the movement, it rotates due to the compression, further cleaning the surface of the raw material. When the connecting seat 607 moves downward, it compresses the spring 610. When the top of the lifting frame 502 rises to the top of the elevated frame 2, the inclined roller brush 608 is reset by the elastic force of the spring 610. During the reset process, a pushing force is applied to the raw material located at the top of the lifting frame 502, pushing it to the top of the elevated frame 2 to avoid material jamming. The top of the elevated structure 2 is inclined, allowing the raw material to roll naturally into the arc-shaped groove 506. At this time, the pusher cylinder 507 can be activated to transport the raw material to the next processing area. After the first raw material leaves the lifting frame 502, the lifting cylinder 504 drives the lifting frame 502 to descend, which in turn drives the connecting arm 704 to descend. When the movable rack 705 contacts the incomplete gear 703, the meshing of the incomplete gear 703 and the movable rack 705 drives the rotating arm 702 to rotate, causing the lower blocking cylinder 707 to rotate again to the bottom of the rotating groove 706, that is, below the raw material conveying bed 1. This releases the lower blocking cylinder 707 and the upper blocking cylinder 708 from limiting the second raw material. At this time, the second raw material automatically falls to the top of the lifting frame 502 after the lifting frame 502 has completely descended, and the third raw material automatically enters between the lower blocking cylinder 707 and the upper blocking cylinder 708, realizing automatic filling. The next raw material to be conveyed is not affected by the friction when the lifting frame 502 rises. To prevent the rotating shaft 701 from rotating without the gravity of the upper blocking cylinder 708, the spring plate 710 is compressed when the rotating arm 702 rotates to a near-vertical state. The spring force of the spring plate 710 allows the rotating arm 702 to return to its normal position.
