Technical Field

[0001] This utility model relates to a buffer, and more particularly to an adjustable angle buffer for raw grain. Background Technology

[0002] Buffers are a common device used in grain transfer. The feed inlet of the buffer is usually connected to the feed chute or feeding equipment. However, during installation, due to installation errors of the buffer and the feeding equipment, there is an angle difference between the feed chute and the feed inlet of the buffer, which makes the installation of the feed chute and the feed inlet of the buffer extremely inconvenient. Utility Model Content

[0021] like Figure 1 and Figure 2As shown, an adjustable-angle buffer for raw grain includes a transfer tank 1. The transfer tank 1 is equipped with an inlet pipe 2 and an outlet pipe 3. The inlet pipe 2 is connected to an inlet chute or to a grain feeding device. A fan-shaped notch 7 is formed on the outer wall of the transfer tank 1, facing the inlet pipe 2. A fan-shaped cover 8 is provided at the outlet end of the inlet pipe 2 to cover the fan-shaped notch 7, and the arc length of the fan-shaped cover 8 is greater than the arc length of the fan-shaped notch 7. When the fan-shaped cover 8 is installed on the transfer tank 1, the transfer tank 1 forms a cylindrical body, allowing grain to enter the tank body only through the inlet pipe 2 and then exit through the outlet pipe 3. In this embodiment, rotating shafts 6 are provided at both ends of the transfer tank 1. Preferably, an arc-shaped plate is provided at the included angle of the fan-shaped notch 7, and the arc-shaped plate is integral with the side wall of the transfer tank 1. That is, in rear view projection... On the surface, the fan-shaped notch 7 is "W" shaped, thus providing a mounting component for the installation of the rotating shaft 6. Moreover, the rotating shaft 6 can be installed in the center. The front and rear side walls of the fan-shaped cover 8 are hinged to the corresponding rotating shaft 6. Therefore, when the buffer is installed, when a circumferential thrust is applied to the fan-shaped cover 8, the fan-shaped cover 8 can rotate relative to the transfer tank 1, which facilitates the alignment of the feed pipe 2 and the feed chute. In this embodiment, the included angle between the feed pipe 2 and the discharge pipe 3 is an obtuse angle, and the included angle between the feed pipe 2 and the discharge pipe 3 is also kept stable by the pre-locking mechanism 5. Since there is an obtuse angle between the feed pipe 2 and the discharge pipe 3, the feed pipe 2 will rotate relative to the transfer tank 1 under the action of gravity. In this embodiment, the included angle between the feed pipe 2 and the discharge pipe 3 can be kept stable by the pre-locking mechanism 5, which makes the installation of the buffer convenient.

[0022] In this embodiment, as Figure 3As shown, the pre-locking mechanism 5 includes a hinge shaft 53 and a pair of hinge seats 51. Both ends of the hinge shaft 53 are hinged to the hinge seats 51, and torsion springs 52 are installed at both ends of the hinge shaft 53. A bushing is fitted in the middle of the hinge shaft 53, and a connecting rod 55 is provided on the bushing. A protruding hook 56 is provided on the end face of the connecting rod 55 near the transfer tank 1. Multiple barbs 57 matching the hooks 56 are provided on the outer wall of the transfer tank 1, and the barbs 57 are distributed circumferentially. Preferably, the back of the barb 57 is a wedge-shaped surface. When adjusting the angle between the inlet pipe and the outlet pipe, applying a pushing force to the inlet pipe causes it to rotate clockwise, while applying a pulling force causes it to rotate counterclockwise. During angle adjustment, the hook 56 can be disengaged from the barb 57, facilitating the adjustment of the inlet pipe's position. After the position is adjusted, the hook 56 is released. Under the action of the torsion spring 52, the groove 58 between the barbs 57 moves, causing the hook 56 to enter the groove 58. Then, the external force on the inlet pipe is removed, and the inlet pipe rotates away from the barb 57 under the action of gravity. At this time, the hook 56 hooks onto the barb 57, preventing the angle between the inlet pipe and the outlet pipe from changing under the action of gravity. During installation, the angle between the inlet pipe and the outlet pipe is first adjusted to a suitable angle for connection with the feed chute, and then the inlet pipe is loosened. At this time, there may still be a certain gap between the hook 56 and the barb 57. Under the action of gravity, the inlet pipe will rotate at a certain angle, and then the hook 56 hooks onto the barb 57. Although the inlet pipe will rotate at a certain angle, the angle of deflection is small. When installing with the feed chute, it is easy to align the inlet pipe opening with the feed chute opening, which facilitates the installation of the buffer and the feed chute.

[0023] In this embodiment, as Figure 4 As shown, the barbs 57 are evenly distributed in the circumferential direction. Therefore, the gap between adjacent barbs 57 is fixed. In other words, the angle between the outlet pipe and the inlet pipe can be determined by which barb 57 the hook 56 is hooked with. This allows for better adjustment of the angle between the outlet pipe and the inlet pipe, preparing for the installation of the feed chute.

[0024] In this embodiment, as Figure 2 As shown, the inner cavity of the transfer tank 1 is equipped with a buffer plate 4. The buffer surface of the buffer plate 4 faces the feed pipe 2. After the grain enters the transfer tank 1 from the inlet pipe, the impact of the grain on the transfer tank 1 can be reduced by the buffer plate 4, thereby extending the service life of the buffer.

[0025] In this embodiment, the central angle of the barb 57 is 30 degrees, and the central angle of the sector cover 8 is 30 degrees larger than the central angle of the sector gap 7. Therefore, after installation, the sector cover 8 can completely cover the sector gap 7. Moreover, the sector cover 8 can cover the sector gap 7 even when the hook 56 is hooked by any barb 57, thus ensuring the reliability of the buffer.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
