Description

Technical Field

[0001] This utility model relates to the field of rice production and processing technology, specifically to a rice leveling device for rice production. Background Technology

[0002] In the actual rice production process, many stages require the rice to be evenly spread. Taking rice quality inspection as an example, accurately determining key indicators such as rice quality and impurity content requires the rice to be evenly spread on a conveyor belt for inspection using advanced image recognition technology or manual methods. Uneven rice accumulation leads to inaccurate test results, affecting the assessment of rice quality. In the rice drying stage, evenly spreading the rice allows hot air to penetrate the rice layer evenly, avoiding over- or under-drying in certain areas, thereby improving drying efficiency and quality, and ensuring the rice's taste and storage performance. In the weighing stage before packaging, evenly spreading the rice helps to accurately measure its volume and weight, ensuring accurate and consistent packaging.

[0003] However, current rice production largely relies on manual leveling using simple tools (such as scrapers). This method has many drawbacks: it is not only inefficient and unable to meet the needs of large-scale production, but also labor-intensive, with prolonged operation easily causing worker fatigue and making it difficult to guarantee uniform leveling results. Furthermore, manual operation is greatly affected by human factors; differences in the skills and experience of different operators can lead to inconsistent leveling quality, thus impacting rice production efficiency and quality. Utility Model Content

[0004] The purpose of this invention is to provide a rice leveling device for rice production, addressing the problem that current rice production largely relies on manual leveling using simple tools (such as scrapers). This method has many drawbacks: it is inefficient, failing to meet the needs of large-scale production, and involves high labor intensity, easily causing worker fatigue and resulting in inconsistent leveling quality. Furthermore, manual operation is significantly affected by human factors; differences in skill and experience among operators lead to inconsistent leveling quality, thus impacting rice production efficiency and quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a belt conveyor line, wherein an installation side plate is fixedly installed on the rear side of the upper end of the belt conveyor line, a feed hopper is fixedly installed on the rear side of the upper end of the installation side plate, a conveying trough is fixedly connected to the bottom of the feed hopper, a conveying motor is fixedly installed at the rear end of the conveying trough, a conveying shaft is fixedly installed on the front drive shaft of the conveying motor, a spiral conveying blade is fixedly installed on the outer curved surface of the conveying shaft, and a discharge port is fixedly connected to the bottom of the front end of the conveying trough;

[0006] A U-shaped support frame is fixedly installed on the front upper side of the mounting side plate. An electric telescopic rod is fixedly installed through the middle of the upper end of the U-shaped support frame. A lifting frame is fixedly installed on the telescopic part at the bottom of the electric telescopic rod. An adjusting shaft is rotatably connected to the inner side of the lifting frame via a rotating shaft. A scraper for leveling the rice at the upper end of the belt conveyor is fixedly installed on the outer curved surface of the middle of the adjusting shaft. A control motor is fixedly installed on the outer side of the upper end of the lifting frame. A first synchronous pulley is fixedly installed on the transmission shaft part of the control motor. A second synchronous pulley is connected to the outer end of the first synchronous pulley via a synchronous belt drive.

[0007] Preferably, there are two mounting side plates, which are symmetrically distributed on the rear side of the upper end of the belt conveyor.

[0008] Preferably, the conveying shaft is rotatably connected to the middle of the conveying trough via a rotating shaft.

[0009] Preferably, vertical slide bars are fixedly installed on both sides of the upper end of the lifting frame.

[0010] Preferably, there are two vertical slide rods, which are symmetrically distributed on both sides of the upper end of the lifting frame, and the upper end of the vertical slide rod is movably connected to the upper end of the U-shaped support frame.

[0011] Preferably, the second synchronous pulley is fixedly installed on the outer curved surface of the side end of the adjusting shaft, and a through opening is provided on the upper end of the lifting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When the conveyor motor is turned on, it drives the conveyor shaft to rotate. When the conveyor shaft rotates, it drives the spiral conveyor blades to rotate. When the spiral conveyor blades rotate, they push the rice flowing into the conveyor trough forward. As the rice is pushed forward, it is continuously discharged downward through the discharge port to the conveyor belt at the top of the belt conveyor line. When the rice is discharged to the conveyor belt at the top of the belt conveyor line, the belt conveyor line is turned on by control. When the belt conveyor line is turned on, it will transport the rice forward. As the rice is transported forward, the scraper will scrape and flatten the rice, thereby facilitating continuous flattening of the rice.

[0014] This invention also features a lifting frame that moves vertically when the electric telescopic rod extends or retracts. This vertical movement of the lifting frame, in turn, causes the adjusting shaft to move vertically, which in turn moves the scraper vertically to adjust the leveling position. Simultaneously, a control motor is activated, which in turn rotates the adjusting shaft. This rotation of the adjusting shaft, in turn, causes the scraper to swing, adjusting the leveling angle. This allows for continuous leveling of the rice while facilitating vertical and horizontal movement and swing adjustment of the scraper's leveling position and angle. Attached Figure Description

[0021] Please see Figure 1-4This utility model provides a technical solution for a rice leveling device for rice production: it includes a belt conveyor line 1, and two mounting side plates 2 are fixedly installed on the rear side of the upper end of the belt conveyor line 1, which are symmetrically distributed on the rear side of the upper end of the belt conveyor line 1. A feeding hopper 3 is fixedly installed on the rear side of the upper end of the mounting side plate 2. A conveying trough 4 is fixedly connected to the bottom of the feeding hopper 3. A conveying motor 5 is fixedly installed at the rear end of the conveying trough 4. A conveying shaft 6 is fixedly installed on the front drive shaft of the conveying motor 5. The conveying shaft 6 is rotatably connected to the middle of the conveying trough 4 through a rotating shaft. Spiral conveying blades 7 are fixedly installed on the outer curved surface of the conveying shaft 6. A discharge port 8 is fixedly connected to the bottom of the front end of the conveying trough 4.

[0022] A U-shaped support frame 9 is fixedly installed on the upper front side of the mounting side plate 2. An electric telescopic rod 10 is fixedly installed through the middle of the upper end of the U-shaped support frame 9. A lifting frame 11 is fixedly installed on the bottom telescopic part of the electric telescopic rod 10. Two vertical slide rods 18 are fixedly installed on both sides of the upper end of the lifting frame 11, symmetrically distributed on both sides of the upper end of the lifting frame 11. The upper end of the vertical slide rods 18 is movably connected to the upper end of the U-shaped support frame 9, so that the vertical movement limit of the lifting frame 11 is achieved through the vertical slide rods 18. An adjusting shaft 12 is rotatably connected to the inner side of the lifting frame 11 via a rotating shaft. A scraper 13 for leveling the rice at the upper end of the belt conveyor 1 is fixedly installed on the outer curved surface of the middle part of the adjusting shaft 12. A control motor 14 is fixedly installed on the outer side of the upper end of the lifting frame 11. A first synchronous pulley 15 is fixedly installed on the outer drive shaft of the control motor 14. A second synchronous pulley 16 is connected to the outer end of the first synchronous pulley 15 via a synchronous belt. The second synchronous pulley 16 is fixedly installed on the outer curved surface of the side end of the adjusting shaft 12. A through opening 17 is provided on the upper end of the lifting frame 11.

[0023] Working principle: In use, this utility model feeds the rice to be leveled into the hopper 3. When the rice is fed into the hopper 3, the rice at the bottom of the hopper 3 flows into the conveying trough 4. The conveying motor 5 is turned on, which drives the conveying shaft 6 to rotate. When the conveying shaft 6 rotates, it drives the spiral conveying blades 7 to rotate. When the spiral conveying blades 7 rotate, they push the rice flowing into the conveying trough 4 forward. When the rice is pushed forward, it is continuously discharged downward through the discharge port 8 to the conveyor belt section at the upper end of the belt conveyor line 1. When the rice is discharged to the conveyor belt section at the upper end of the belt conveyor line 1, the belt conveyor line 1 is turned on. When the belt conveyor line 1 is turned on, it conveys the rice forward. When the rice is conveyed forward, the scraper 13 scrapes and flattens the rice, thus achieving the effect of continuous leveling of the rice.

[0024] The electric telescopic rod 10 is extended and retracted by controlling its operation. When the electric telescopic rod 10 extends and retracts, it drives the lifting frame 11 to move up and down linearly. When the lifting frame 11 moves up and down linearly, it drives the adjusting shaft 12 to move up and down linearly. When the adjusting shaft 12 moves up and down linearly, it drives the scraper 13 to move up and down linearly to adjust the leveling position. At the same time, the control motor 14 is turned on and rotated. When the control motor 14 rotates, it drives the first synchronous pulley 15 to rotate. When the first synchronous pulley 15 rotates, it drives the second synchronous pulley 16 to rotate via the synchronous belt drive. When the second synchronous pulley 16 rotates, it drives the adjusting shaft 12 to rotate. When the adjusting shaft 12 rotates, it drives the scraper 13 to swing and adjust the leveling angle. This allows for continuous leveling of the rice while facilitating the vertical and horizontal linear movement and swing adjustment of the scraper 13's leveling position and angle.
