[0002] A scraper conveyor is a continuous conveying device that uses a scraper chain to scrape materials in a closed or open trough. It mainly consists of a head, transition trough, middle trough, chain, scrapers, and tail. The head is equipped with a drive unit. The casing is usually a closed rectangular cross-section, welded from steel plates, which has good sealing performance and can prevent dust from flying and material from leaking. The scrapers are evenly fixed on the chain, and the chain is wound around the sprockets at the head and tail to form a closed circulation system. The shape and material of the scrapers are determined according to the characteristics of the conveyed material. Common scrapers include metal scrapers and high-polymer wear-resistant scrapers.

[0003] In the existing technology, the grain scraper conveyor is large in size, making it inconvenient to flexibly adjust the conveying angle of the machine according to the usage requirements. This makes it difficult to meet the usage requirements in different environments and affects the adaptability during use. Utility Model Content

[0011] Compared with the prior art, this utility model provides a grain scraper conveyor with the following advantages: 1. This grain scraper conveyor has a connecting plate fixedly connected to the end of the machine casing away from the discharge port. A cylinder fixed on the upper surface of the bottom plate provides power for adjusting the angle of the machine casing. The inner wall of the connecting plate has a slotted opening. An adjusting rod sliding inside the slotted opening is movably connected to the sleeve at the end of the piston rod of the cylinder. When the piston rod of the cylinder extends or retracts, the connecting plate is pushed through the cooperation of the sleeve and the adjusting rod, which drives the machine casing to rotate around the shaft, thereby adjusting the tilt angle of the machine casing to adapt to different feeding and discharging requirements and improve the versatility of the device.

[0012] 2. This grain scraper conveyor uses a motor as its power source. After starting, its output shaft drives the fixedly mounted first gear to rotate. The first gear meshes with the second gear fixedly mounted at the end of one of the rotating rollers, transmitting power to the rotating roller. The two rotating rollers are rotatably connected to the inner wall of the machine casing. Two sprockets are fixedly mounted on the roller walls respectively. Chains are mounted on the side walls of two adjacent sprockets. When one of the rotating rollers rotates, the other rotating roller rotates synchronously through the cooperation of the sprocket and the chain, realizing the cyclic transmission of the chain.

[0013] 3. This grain scraper conveyor has multiple scrapers fixedly connected to the side walls of two chains. The scrapers move synchronously with the chains, and the side of the scraper facing away from the chain has a rounded corner to avoid scratching the inner wall of the machine casing. At the same time, the side wall of the scraper is slidably set on the inner wall of the machine casing to ensure that the scraper can move closely against the inner wall of the machine casing and push the grain in the machine casing forward. During conveying, the grain falls into the machine casing from the feed port and is guided by the guide table to the movement path of the scraper. The rotating scraper continuously scrapes the grain forward until it is discharged from the discharge port, completing the grain conveying operation. Attached Figure Description

The housing 5 is fixedly connected to the top of the swing seat 4. An end cover 6 is fixedly connected to the top of the housing 5. A feed inlet is opened on the inner wall of the top of the end cover 6. A discharge outlet is provided at the end of the housing 5. Two rotating rollers 7 are rotatably connected to the inner wall of the housing 5. Each of the two rotating rollers 7 has a fixed sleeve on its roller wall. The machine is equipped with two sprockets 8, and chains 9 are fitted on the side walls of two adjacent sprockets 8. Multiple scrapers 10 are fixedly connected to the side walls of the two chains 9. A support frame 11 is fixedly connected to the side wall of the machine housing 5. A motor 12 is fixedly connected to the side wall of the support frame 11. A first gear 13 is fixedly fitted on the output shaft of the motor 12. The end of one of the rollers 7 extends to the outside of the machine housing 5 and is fixedly fitted with a second gear 14. The first gear 13 and the second gear 14 are meshed with each other.

[0018] Multiple scrapers 10 have rounded corners on the side opposite to the chain 9. The sidewalls of the scrapers 10 are slidably mounted on the inner wall of the housing 5. The fixing seat 2 is a semi-circular plate. The bottom of the housing 5 is pressed against the surface of the fixing seat 2.

[0019] A connecting plate 15 is fixedly connected to one end of the housing 5 away from the discharge port. A cylinder 16 is fixedly connected to the upper surface of the base plate 1. A strip-shaped opening is opened on the inner wall of the connecting plate 15. An adjusting rod 17 is slidably connected to the inner wall of the strip-shaped opening. A sleeve 18 is fixedly connected to the end of the piston rod of the cylinder 16. The sleeve 18 is movably sleeved on the rod wall of the adjusting rod 17.

[0020] The base plate 1 serves as the basic load-bearing component of the entire device, providing a stable mounting reference surface for structures such as the fixed seat 2 and cylinder 16. The fixed seat 2 is fixedly connected to the upper surface of the base plate 1 and is set as a semi-circular plate. The rotating shaft 3 rotatably connected inside provides rotational support for the swing seat 4. The top of the swing seat 4 is fixedly connected to the housing 5, and the bottom of the housing 5 is pressed against the surface of the fixed seat 2 to ensure the stability of the housing 5 in the non-adjusted state.

[0021] A connecting plate 15 is fixedly connected to the end of the housing 5 away from the discharge port. A cylinder 16 fixed on the upper surface of the base plate 1 provides power for the angle adjustment of the housing 5. A strip-shaped opening is opened on the inner wall of the connecting plate 15. An adjusting rod 17 sliding in the strip-shaped opening is movably connected to the sleeve 18 at the end of the piston rod of the cylinder 16. The inner wall of the strip-shaped opening has a groove that fits the adjusting rod 17. The end of the adjusting rod 17 is embedded in the groove to ensure the stability of the adjusting rod 17 when sliding. When the piston rod of the cylinder 16 extends or retracts, the connecting plate 15 is pushed through the cooperation of the sleeve 18 and the adjusting rod 17, which drives the housing 5 to rotate around the rotating shaft 3, thereby realizing the adjustment of the tilt angle of the housing 5 to adapt to the feeding and discharging requirements of different heights and improve the versatility of the device.

[0022] The housing 5 is the core channel for grain conveying. The end cap 6, which is fixedly connected to the top of the housing, serves as a protective measure to prevent grain from splashing during the conveying process. The inlet on the inner wall of the top of the end cap 6 is used to introduce the grain to be conveyed. The end of the housing 5 is provided with an outlet for discharging the conveyed grain.

[0023] The support frame 11 is fixedly connected to the side wall of the housing 5, providing a stable installation support for the motor 12 and ensuring the stability of the motor 12 during operation. The motor 12 serves as a power source. After starting, its output shaft drives the fixedly sleeved first gear 13 to rotate. The first gear 13 meshes with the second gear 14 fixedly sleeved at the end of one of the rollers 7, transmitting power to the roller 7. The two rollers 7 are rotatably connected to the inner wall of the housing 5. Two sprockets 8 are fixedly sleeved on their roller walls respectively. Chains 9 are sleeved on the side walls of two adjacent sprockets 8. When one of the rollers 7 rotates, the other roller 7 is driven to rotate synchronously through the cooperation of the sprocket 8 and the chain 9, realizing the cyclic transmission of the chain 9.

[0024] Multiple scrapers 10 are fixedly connected to the side walls of the two chains 9. The scrapers 10 move synchronously with the chains 9. The side of the scraper 10 facing away from the chains 9 has a rounded corner to avoid scratching the inner wall of the housing 5. At the same time, the side wall of the scraper 10 is slidably set on the inner wall of the housing 5 to ensure that the scraper 10 can move closely against the inner wall of the housing 5 and push the grain in the housing 5 forward. During the conveying process, the grain falls into the housing 5 from the feed port and is guided by the guide table 19 to the movement path of the scraper 10. The rotating scraper 10 continuously scrapes the grain forward until it is discharged from the discharge port, thus completing the grain conveying operation.

[0025] The entire device uses a gear, sprocket and chain transmission structure driven by motor 12 to achieve stable cyclic movement of scraper 10, which, together with guide table 19, ensures smooth grain conveying; the angle adjustment structure driven by cylinder 16 adapts to different working conditions; the coordinated operation of various structures ensures the efficiency and stability of grain conveying, while also improving the versatility and structural reliability of the device, making it suitable for various grain conveying scenarios.

[0026] To enhance the structural strength of casing 5, such as Figure 1-4 As shown, a guide platform 19 is fixedly connected to the inner wall of the housing 5 below the feed inlet. The side wall of the guide platform 19 is set as an arc surface. The scraper 10 is slidably disposed on the side wall of the guide platform 19.
