Technical Field

[0001] This utility model belongs to the technical field of conveying mechanisms, specifically relating to a conveying mechanism for a mobile grain unloader. Background Technology

[0002] Grain unloaders are mostly agricultural machinery and equipment, mainly used for the collection, loading, unloading, and storage of bulk grain in grain warehouses. They can unload bulk grain within a 180-degree range, have high working efficiency, are flexible in use, and are easy to operate. They use a screw rod to transport the material at the bottom to a conveyor belt and move it through the vehicle body, saving manpower and material resources.

[0003] Existing grain loader machines are not convenient for extracting materials on thin ground, requiring manual shoveling, which is inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a mobile grain unloader conveying mechanism with a simple structure, which facilitates the collection and transportation of materials from the ground to higher points. It also has a baffle mechanism, which can effectively collect materials even when there are few materials. It is highly practical and suitable for widespread application.

[0005] This utility model provides the following technical solution: a mobile grain unloader conveying mechanism, including an unloader hopper, a feed inlet provided at the lower front of the unloader hopper, a circular array of blades installed inside the unloader hopper via a rotating shaft, a feed outlet provided at the lower rear of the unloader hopper, an inclined plate fixedly provided at the feed outlet of the unloader hopper, the inclined plate being inclined towards the center and fixedly provided with a feeding column, and a threaded push rod provided inside the feeding column;

[0006] The hopper has symmetrical rotating frames on both sides via a rotating shaft. A drive motor is provided on one side of the rotating frame. The rotating frame extends to the outside of the hopper and is connected by a connecting shaft. A sleeve plate is fitted on the connecting shaft. A baffle strip of the same length as the feed inlet is fixed below the sleeve plate.

[0007] The rotating frame is provided with a through sliding rail, which is penetrated by a limiting block of the rotating shaft. A support spring is fixedly provided at the end of the sliding rail facing the connecting shaft, and the support spring rests on the limiting block.

[0008] Preferably, the bottom of the feed inlet is provided with a scraper that fits against the ground, the front end of the baffle is provided with a chamfer corresponding to the scraper, the upper end of the baffle is provided with a sloping arc surface, and when the scraper extends into the chamfer, the center of the sloping arc surface coincides with the rotation axis.

[0009] Preferably, the sleeve plate is fixedly provided with an extension foot on the other side of the stop bar, and the lower surface of the extension foot is provided with a friction surface.

[0010] Preferably, the top of the blade is in contact with the inner wall of the feed hopper, and the flat threaded plate on the threaded push rod is in contact with the inner wall of the feed column.

[0011] The beneficial effects of this utility model are as follows: It has a simple structure, making it easy to collect and transport materials from the ground to a higher point. It also features a baffle mechanism, allowing for effective collection even with small amounts of material. It is highly practical, as detailed below:

[0012] This utility model features a hopper. When collecting materials from the ground, the hopper is positioned at the material location. The rotating shaft rotates, scooping the material entering the feed inlet to the conveying inlet. From the conveying inlet, the material enters the inclined plate and slides from the inclined plate to the bottom of the feeding column in the chamber. The rotating threaded push rod drives the material upward. When there is little material on the ground, the hopper is close to the ground, and the scraper scoops the material into the feed inlet. When the material is pushed to the edge, the rotating frame rotates, pressing one end of the connecting shaft against the ground. The drive mechanism on it continuously applies downward pressure, causing the planes of the extension foot and the stop bar to be in contact with the ground. As the hopper continues to advance and scoop material, the extension foot of the rotating frame presses against the ground, and its friction surface engages with the ground, preventing one end of the rotating frame from moving. The rotating frame slides relative to the hopper, and the limiting block slides on the sliding rail. The scraper moves closer to the stop bar, which blocks the material pushed up by the scraper, pushing the material into the feed inlet, making the hopper collect material more efficiently.

A stop bar 17 of the same length as the feed inlet 3 is fixed below the sleeve plate 9. The stop bar 17 can rotate through the sleeve plate 9. When the stop bar 17 rotates with the rotating frame 6 and contacts the ground, it deflects and adheres to the ground under the action of the sleeve plate 9. A through sliding rail 7 is provided on the rotating frame 6. The sliding rail 7 is penetrated by the limiting block 14 of the rotating shaft. A support spring is fixed at the end of the sliding rail 7 facing the connecting shaft 8. Spring 13 supports the limit block 14, which slides along the sliding rail 7. When the baffle 17 is in contact with the ground, if the hopper 1 continues to move forward to scoop material, the rotating frame 6 slides relative to the hopper 1. The bottom of the feed inlet 3 is provided with a scraper 15 that is in contact with the ground. The front end of the baffle 17 is provided with a chamfer corresponding to the scraper 15. The upper end of the baffle 17 is provided with a sloping arc surface 18. When the scraper 15 extends into the chamfer, the center of the sloping arc surface 18 coincides with the rotating shaft 11. The baffle 17 blocks the material pushed up by the scraper. The sleeve 9 is fixedly provided with an extension foot 16 on the other side of the baffle 17.

Figure 1-4 When collecting materials from the ground, the hopper 1 is positioned at the material location, and the rotating shaft 11 rotates, scooping the material entering the feed inlet 3 to the conveying inlet 12. From the conveying inlet 12, the material enters the inclined plate 5 and slides from the inclined plate 5 to the bottom of the feeding column 2 in the chamber. The threaded push rod 10 rotates, causing the material to rise. When there is little material on the ground, the hopper 1 is close to the ground, and the scraper 15 shovels the material from the ground into the feed inlet 3. When the material is pushed to the edge, the rotating frame 6 rotates, causing the connecting shaft 8 to... When the end of the rotating frame 6 is pressed against the ground, the driving mechanism on it continuously applies downward pressure, causing the planes of the extension foot 16 and the baffle 17 to be in contact with the ground. As the hopper 1 continues to move forward to scoop material, the extension foot 16 of the rotating frame 6 is pressed against the ground, and its friction surface is pressed against the ground, making one end of the rotating frame 6 unable to move. The rotating frame 6 slides relative to the hopper 1, the limiting block 14 slides on the sliding rail 7, the scraper 15 moves closer to the baffle 17, and the baffle 17 blocks the material pushed up by the scraper, pushing the material into the feed inlet 3.
