[0001] The utility model belongs to the technical field of grain storage and logistics equipment, and particularly relates to a pneumatic chute turning mechanism. Background Art
[0002] As the cornerstone of the national economy and people's lives, the storage of grain is not only related to food safety, but also directly affects the stability of the market and the healthy development of the agricultural economy. In this context, building an efficient and safe grain storage system has become a vital task. Advanced storage technology and facilities can not only effectively maintain the freshness and nutritional value of grain, but also significantly increase the storage capacity, providing a solid material foundation for coping with market fluctuations.
[0003] At present, many grain storage companies have gradually adopted the chute loading system, which is a method of feeding at multiple points at the same time to optimize storage efficiency, reduce operation time, and reduce the accumulation of impurities caused by centralized loading, thereby ensuring the overall quality of the grain entering the warehouse. The system realizes the loading of grain at a fixed point by opening and closing multiple grain discharge ports dispersedly arranged on the chute.
[0004] However, in the process of using chutes to load grain into warehouses, the technical structures of fixed-point grain drop are uneven. There are also cases where manual gates, slides or simple mechanical devices are used to open and close the grain outlets. The above methods have problems such as slow response, complicated operation and low efficiency, and are difficult to adapt to the needs of fast and stable switching of fixed-point grain drop in chute loading systems. Utility Model Content

The sealing plate is located on the upper side of the transmission shaft, and the guide plate is located on the lower side of the transmission shaft. The sealing plate and the guide plate are fixed together at the ends facing the grain inlet, and the other ends of the two are open. The size of the sealing plate is the same as the size of the lower grain outlet. Through the rotation of the transmission shaft, the sealing plate can be flush with the bottom surface of the chute shell, thereby blocking the lower grain outlet.
[0008] Furthermore, the guide plate is a bent plate, the rear section of the guide plate is bent downward, and the bending angle of the guide plate is an obtuse angle.

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below.
[0017] Embodiment 1: The utility model provides a Figure 1The pneumatic chute flipping mechanism shown is used to quickly change the flow direction of grain in the chute, so that the grain in the chute can be dropped or moved forward at a fixed point. Specifically, the flipping mechanism includes a chute shell 4, a cylinder 1, and a flap device 2. The chute shell 4 is a part of the entire chute. A corresponding grain outlet is set at the bottom of the chute shell 4. The lower part of the grain outlet corresponds to a granary, etc. The flap device 2 is installed at the lower grain outlet. The flap device 2 is driven by the cylinder 1 to close or open the corresponding lower grain outlet, thereby controlling whether the grain continues to flow in the chute or flows out of the lower grain outlet here.
[0018] The flap device 2 includes a flap 5, a rotating rod 6, a flap device fixing seat 7 and a transmission shaft 8. The flap device fixing seats 7 are symmetrically fixed on both sides of the bottom of the chute shell 4. The flap device fixing seats 7 can adopt the existing shaft seat structure, or according to the structure of the chute shell 4, corresponding mounting plates can be fixed on both sides under the chute, and a through hole is set in the middle of the mounting plate, and a bearing is installed in the through hole.
[0019] A transmission shaft 8 is mounted in the flap device fixing seat 7, and a flap 5 is fixed on the transmission shaft 8. The flap 5 is located between the two flap device fixing seats 7. The size of the flap 5 is the same as the size of the lower grain opening on the bottom surface of the chute shell 4. The flap 5 is fixedly installed with the transmission shaft 8 by welding or clamping. When the transmission shaft 8 rotates, the end of the flap 5 facing the grain feeding side is tilted upward, thereby cutting off the grain flow and allowing the grain to flow out of the chute 4 from the opened lower grain opening.
[0020] like Figure 2 and 3 As shown, the end of one side of the transmission shaft 8 extends outward and is fixedly installed with the rotating rod 6. The end of the rotating rod 6 is hinged to the end of the telescopic rod of the cylinder 1 through a pin, and a cylinder seat is fixed on the outer side wall of the chute shell 4 on the same side. The tail end of the cylinder 1 is hinged on the cylinder seat. By controlling the extension and contraction of the cylinder 1, the cylinder 1 pushes the rotating rod 6 to rotate, thereby driving the transmission shaft 8 and the flap 5 to rotate.
[0021] When the cylinder 1 extends, the rotating rod 6 is pushed to make the flap 5 tilt upward, opening the lower grain port to divert the grain; when the cylinder 1 contracts, the rotating rod 6 is pulled to make the flap 5 downward, flattening the bottom surface of the chute, so that the grain can flow continuously in the chute 4.
[0022] The utility model drives the flap 5 to open and close by the cylinder 1, so as to quickly change the flow direction of the material in the chute 4 without interrupting the flow of the material, thereby achieving the purpose of fixed-point unloading or continuous transmission.
[0023] Embodiment 2: Based on embodiment 1, Figure 2 and Figure 3As shown, the flap 5 in the utility model includes a sealing plate 51 and a guide plate 52, and the sealing plate 51 and the guide plate 52 are respectively fixed on the upper and lower sides of the transmission shaft 8, wherein the sealing plate 51 is fixed on the upper side of the transmission shaft 8, and the guide plate 52 is fixed on the lower side of the transmission shaft 8, and the sealing plate 51 and the guide plate 52 are combined together at the ends facing the grain inlet, and the other ends of the two are opened, so that the sealing plate 51 and the guide plate 52 form a triangular structure with the tip facing the grain feeding side.
[0024] The size of the sealing plate 51 is the same as that of the lower grain outlet. The sealing plate 51 and the guide plate 52 are driven to rotate simultaneously by the rotation of the transmission shaft 8. When the cylinder 1 contracts, the transmission shaft 8 drives the sealing plate 51 to flip toward the grain feeding side, so that the sealing plate 51 can be laid flat on the bottom of the chute shell 4. The sealing plate 51 is flush with the bottom surface of the chute shell 4, and the lower grain outlet is completely blocked; when the cylinder 1 extends, it pushes the transmission shaft 8 to rotate, and the sealing plate 51 is tilted upward at the end toward the grain feeding side, so that the lower grain outlet is opened, and the tilted sealing plate 51 forms a baffle to block the grain running in the chute 4, so that the grain is diverted from the lower grain outlet. At this time, the guide plate 52 can block the transmission shaft 8 to form a flat guide surface to prevent grain from falling into the corners formed by the transmission shaft 8, thereby avoiding grain loss.
[0025] The guide plate 52 is a bent plate, the front section of which is fitted with the sealing plate 51 to form a triangular structure, and the rear section of which is further bent downward, and the deflection angle becomes larger. After the flap 5 is lifted by the transmission shaft 8, the front section of the guide plate 52 is tilted upward to form an inclined surface, and the rear section is nearly vertical after flipping. During the flow of grain, the rear section blocks the grain to prevent splashing.
[0026] Furthermore, a flap positioning block 3 is installed on the inner side of the chute 4, and the flap positioning block 3 is fixed on the inside of the chute 4 at the front end of the flap 5. When the flap 5 rotates, the front end of the flap 5 can touch the flap positioning block 3 to prevent the flap 5 from rotating excessively.
[0027] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
