[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] First Embodiment

[0035] Please refer to the following: Figure 1 and Figure 2A hoist package for use in a grain dryer includes: a support component 1, the support component 1 including a base 11, a housing 12, a feed hopper 13 and a discharge pipe 14, the housing 12 being mounted above the base 11, the feed hopper 13 being mounted on one side of the housing 12 and the discharge pipe 14 being mounted on the other side of the housing 12;

[0036] Lifting device 2, which is installed inside the outer casing 12, is used to lift the grain;

[0037] A pushing device 4 is mounted on the housing 12 and located below the discharge pipe 14. The pushing device 4 is rotatably connected to the lifting device 2 via a transmission component 3.

[0038] The discharge structure 5 is installed at one end of the discharge pipe 14 and is rotatably connected to the pushing device 4, and is used to adjust the discharge direction of the grain;

[0039] When performing grain lifting operations, the lifting device 2 is activated to guide the grain from the feed hopper 13 into the outer shell 12. The grain falls into the lifting device 2 and is lifted upwards to be discharged from the discharge pipe 14 and the discharge structure 5 into the dryer. At the same time, the lifting device 2 drives the pushing device 4 through the transmission component 3 to adjust the direction of the grain discharge from the discharge structure 5, thereby expanding the area where the grain falls into the dryer, avoiding the accumulation of grain in a fixed area inside the dryer, and improving the drying effect.

[0040] Please refer to the reference again. Figure 1 and Figure 2 The lifting device 2 includes a first roller 21, a second roller 22, a conveyor belt 23, and a plurality of hoppers 24. The first roller 21 and the second roller 22 are mounted on the inner wall of the outer casing 12 and rotate up and down. The first roller 21 and the second roller 22 are connected by the conveyor belt 23, and the conveyor belt 23 is provided with a plurality of hoppers 24 at equal intervals.

[0041] During the grain lifting operation, the motor drives the first roller 21 and the second roller 22 to rotate, thereby driving the loading hopper 24 set on the conveyor belt 23 to rotate in a cycle. At the same time, the grain is guided from the feed hopper 13 into the outer shell 12 and falls into the loading hopper 24. The loading hopper 24 lifts the grain upward and discharges it into the dryer through the discharge pipe 14 and the discharge structure 5, thus completing the grain lifting operation.

[0042] Please refer to the following: Figure 1 , Figure 2 and Figure 3The transmission component 3 includes a drive wheel 31, a transmission belt 32, and a driven wheel 33. The drive wheel 31 passes through the outer shell 12 and is mounted on the first roller 21. The driven wheel 33 is rotatably mounted on the pushing device 4. The drive wheel 31 and the driven wheel 33 are connected by the transmission belt 32.

[0043] When the motor drives the first drum 21 and the second drum 22 to rotate, the first drum 21 drives the drive wheel 31 to rotate, and the drive wheel 31 drives the driven wheel 33 to rotate through the transmission belt 32. The driven wheel 33 drives the push device 4 to work, adjusting the direction of the grain discharged from the discharge structure 5, so that the area where the grain falls into the dryer is expanded.

[0044] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 5 The pushing device 4 includes a mounting box 41, a cam 42 and a sliding groove 421. The mounting box 41 is mounted on the outer shell 12. One end of the cam 42 is rotatably mounted in the mounting box 41, and the other end of the cam 42 passes through the mounting box 41 and is connected to the driven wheel 33. The sliding groove 421 is formed on the surface of the cam 42.

[0045] When lifting operations are performed, the first roller 21 drives the drive wheel 31 to rotate, and the drive wheel 31 drives the driven wheel 33 to rotate through the transmission belt 32. The driven wheel 33 drives the cam 42 and the sliding groove 421 on the surface to rotate within the mounting box 41.

[0046] Please refer to the reference again. Figure 2 , Figure 3 , Figure 4 and Figure 5 The pushing device 4 also includes a limiting rod 43, a transmission rod 44 and a connecting rod 45. The limiting rod 43 is fixedly installed in the mounting box 41. One end of the transmission rod 44 is slidably connected to the limiting rod 43, and the other end of the transmission rod 44 is slidably connected to the sliding groove 421. The connecting rod 45 is rotatably installed on the transmission rod 44.

[0047] When the driven wheel 33 drives the cam 42 and the sliding groove 421 to rotate, the drive transmission rod 44 slides in the sliding groove 421. At the same time, the transmission rod 44 drives the connecting rod 45 to move on the limit rod 43. The sliding groove 421 causes the transmission rod 44 to drive the connecting rod 45 to reciprocate.

[0048] Please refer to the following: Figure 2 and Figure 4The discharge structure 5 includes a discharge cylinder 51 and a guide plate 52. The discharge cylinder 51 is installed on the discharge pipe 14, and the guide plate 52 is rotatably installed inside the discharge cylinder 51 and rotatably connected to the connecting rod 45.

[0049] When the transmission rod 44 drives the connecting rod 45 to reciprocate, an arc-shaped groove is provided on the discharge cylinder 51. The connecting rod 45 passes through the arc-shaped groove and drives the guide plate 52 to reciprocate within the discharge cylinder 51. At the same time, the connecting rod 45 also rotates on the transmission rod 44. The direction of the grain discharge from the discharge cylinder 51 is continuously adjusted by the guide plate 52, expanding the area where the grain falls into the dryer and preventing it from accumulating in a fixed area inside the dryer.

[0050] Second Embodiment

[0051] Please refer to the following: Figure 6 and Figure 7 The elevator for the grain dryer also includes a collection structure 6, which is installed inside the base 11 and located below the second roller 22;

[0052] During grain lifting operations, grain is fed from the feed hopper 13 into the outer shell 12 and falls into the loading hopper 24. Inevitably, some grain will spill into the base 11. Furthermore, when the loading hopper 24 is discharging, some undischarged grain may remain inside. As the loading hopper 24 moves downward, it will fall into the base 11. When a large amount of grain accumulates in the base 11, it can easily obstruct the movement of the loading hopper 24, affecting the grain lifting efficiency.

[0053] In this embodiment, when a large amount of grain accumulates in the base 11, the falling grain is collected and discharged by the collection structure 6 to prevent excessive accumulation in the base 11 and thus avoid affecting the operation of the hopper 24.

[0054] Please refer to the reference again. Figure 6 and Figure 7 The collection structure 6 includes a conveying device 61 and a guide plate 62. The conveying device 61 is installed inside the base 11, and the guide plate 62 is installed inside the outer shell 12.

[0055] When grain is introduced from the feed hopper 13, the grain that does not fall into the loading hopper 24 will fall onto the surface of the conveying device 61. At the same time, when the loading hopper 24 finishes discharging and moves downward, the grain remaining inside falls down onto the guide plate 62. The grain slides down onto the conveying device 61 through the guide plate 62. At the same time, the conveying device 61 is started to discharge the grain accumulated on the surface from the base 11, so as to avoid accumulation in the base 11 and affect the efficiency.

[0056] The working principle of the elevator in the grain dryer provided by this utility model is as follows:

[0057] During grain lifting operations, the motor drives the first roller 21 and the second roller 22 to rotate, which in turn drives the loading hopper 24 on the conveyor belt 23 to rotate cyclically, guiding the grain from the feed hopper 13 into the outer casing 12 and into the loading hopper 24. The loading hopper 24 lifts the grain upwards. At the same time, the first roller 21 drives the drive wheel 31 to rotate, which in turn drives the driven wheel 33 to rotate via the transmission belt 32. The driven wheel 33 then drives the cam 42 to rotate, which in turn drives the transmission rod 44 to slide in the sliding groove 42. The feed cylinder 51 slides back and forth within the feed hopper 13, while the transmission rod 44 drives the connecting rod 45 to reciprocate on the limiting rod 43. An arc-shaped groove is provided on the discharge cylinder 51. The connecting rod 45 passes through the arc-shaped groove, driving the guide plate 52 to reciprocate within the discharge cylinder 51. Simultaneously, the connecting rod 45 also rotates on the transmission rod 44. The direction of grain discharge from the discharge cylinder 51 is continuously adjusted by the guide plate 52, expanding the area where grain falls into the dryer and preventing grain from accumulating in a fixed area inside the dryer, thus improving the drying effect. A conveying device 61 is provided. When grain is introduced from the feed hopper 13, grain that does not fall into the loading hopper 24 will fall onto the surface of the conveying device 61. Simultaneously, when the loading hopper 24 finishes discharging and moves downwards, the remaining grain inside falls down onto the guide plate 62, sliding onto the conveying device 61. The conveying device 61 is then activated to discharge the accumulated grain from the base 11, preventing accumulation within the base 11 and thus improving efficiency.

[0058] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
