[0002] Grain dryer is a general term for various grain drying equipment, and can also be called grain dryer, such as corn dryer, rice dryer, rice dryer, wine dregs dryer, etc. We can all call them grain dryers. According to the different drying methods, they can be divided into high-temperature grain dryers or low-temperature grain dryers. Among them, low-temperature grain dryers dry grains through simple wind power, which will not heat the grains. Then, there is no need to cool the grains after drying, and they can be directly stored. Traditional low-temperature grain dryers are larger in size, so the matching feeders are also larger.

[0003] In the prior art, the feeders used with grain dryers are mostly bucket elevators, which lift the grains to the top of the dryer through multiple hoppers that move in a circular motion. However, the existing feeders are connected to the dryer through a fixed feed cylinder. The fixed feed cylinder has a fixed feed position and lacks flexibility. This results in the grains falling into a fixed area during drying if the dryer does not have a bulk material mechanism, and the accumulated grains affect the drying effect. Utility Model Content

[0022] Please refer to Figure 1 and Figure 4As shown, a crossbeam frame 3 is arranged above the outer side of the bucket loading elevator 1, and an electric-controlled coupling 5 is installed above one side of the bucket loading elevator 1 to control the opening and closing of the internal coupling. The electric-controlled coupling 5 is placed above the crossbeam frame 3, and a driving pulley 6 is arranged at one end of the outer side of the electric-controlled coupling 5. The end of the electric-controlled coupling 5 away from the driving pulley 6 is coaxially installed with the upper sprocket inside the bucket loading elevator 1. When the bucket loading elevator 1 is started, the electric-controlled coupling 5 can be used to control whether it drives the driving pulley 6 to rotate.

[0023] Please refer to Figure 1-Figure 4 As shown, a support seat 14 is provided on one side of the upper surface of the beam frame 3, and the support seat 14 is suspended above the dryer, and the support seat 14 is placed on the outside of the discharge barrel 4. A rotating shaft 15 rotates through the surface of the support seat 14, and a driven pulley 16 is provided at one end of the rotating shaft 15. A belt 17 is sleeved on the surface of the driven pulley 16 and the driving pulley 6, and a turntable 18 is provided at the end of the rotating shaft 15 away from the driven pulley 16. When the movable barrel 12 needs to swing, the turntable 18 can be controlled to rotate synchronously by the electric control coupling 5.

[0024] The turntable 18 is placed inside the crossbeam frame 3, and a slide groove 19 is provided on the surface of the turntable 18 on the side away from the rotating shaft 15. An adjusting threaded rod 20 is rotatably installed inside the slide groove 19. An inner hexagonal head 21 is provided at the end of the adjusting threaded rod 20.

[0027] The working principle of the utility model is as follows: the grains are placed inside the feed hopper 2, and the chain inside the bucket-type feeding elevator 1 is driven to rotate by the motor, so that the grains are lifted by the circular movement of the bucket on the chain surface, and the grains flow into the discharge barrel 4, and flow into the dryer through the movable barrel 12 to achieve the drying of the grains. When the movable barrel 12 needs to be kept fixed, it can be separated by controlling the electric control coupling 5 so that the rotation of the internal sprocket wheel will not drive the active pulley 6 to rotate. When the angle of the movable barrel 12 is adjusted, it can be fixed by the cooperation of the fixing bolt 9 and the positioning internal threaded hole 11 to keep the discharge angle of the movable barrel 12 stable. On the contrary, when the movable barrel 12 needs to swing When the fixing bolt 9 is pulled out, the movable barrel 12 can rotate around the center of the docking bucket 10. At this time, the electronically controlled coupling 5 is controlled to be closed, the driving pulley 6 will rotate, and the turntable 18 is driven to rotate through the cooperation of the belt 17 and the driven pulley 16. Then, the pull rope 23 can be adjusted to move up and down through the moving block 22 eccentric to the rotating shaft 15, and then the movable barrel 12 is driven to swing within a certain range through the cooperation of the hook 24 and the docking cross bolt 13 to expand the feeding range. The swing amplitude of the movable barrel 12 can also be controlled according to the usage situation, and the hexagonal head 21 is rotated to control the rotation of the adjustment threaded rod 20, and then the distance between the moving block 22 and the center of the turntable 18 is controlled to achieve adjustment.
