DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1As shown, this embodiment provides a material conveying channel selection mechanism, which is applied between the upper and lower conveying lines. The channel selection mechanism includes a connecting conveying platform 1, a support seat 2, a swing arm 3, a connecting rod 4, and a driving device 5. The two connecting conveying platforms 1 are adjacently arranged in the upper conveying line 6, and the opposite ends of the two connecting conveying platforms 1 are respectively rotatably connected to the upper conveying line 6, the middle part of the swing arm 3 is rotatably connected to the support seat 2, and the two ends of the swing arm 3 are respectively rotatably connected to the adjacent parts of the two connecting conveying platforms 1 through the connecting rod 4, and the driving device 5 is transmission-connected to the swing arm 3. Among them, since the middle part of the swing arm 3 is rotatably connected with the support seat 2, when the swing arm 3 rotates, its two ends will be raised and lowered respectively, thereby driving the two connecting conveying platforms 1 to rotate upward and downward respectively, and the connecting conveying platform rotating downward is connected with the lower conveying line (not drawn in the figure), so as to realize the transportation of materials on the upper conveying line 6 to the lower conveying line, and the connecting conveying platform rotating upward synchronously makes enough space for the materials. When the connecting conveying platform 1 rotates at a small angle, the materials can be transported to the lower conveying line, thereby improving the overall work efficiency. An application scenario of this mechanism is: the materials with the state meeting the requirements are normally transported along the upper conveying line 6, for example, they are correct upward, and at this time, the two connecting conveying platforms 1 are part of the entire upper conveying line 6 and are responsible for the horizontal transportation of the materials; when it is detected that the materials with abnormal state are about to reach the connecting conveying platform 1, for example, they are wrong upward, at this time, the two connecting conveying platforms 1 rotate synchronously, and the materials enter the lower conveying line along the connecting conveying platform rotating downward to receive subsequent processing; then the two connecting conveying platforms are reset to continue the material transportation work.

[0024] like Figure 2 As shown, the swing arm 3 is rotatably connected to the support seat 2 through a rotating shaft 31, and the driving device 5 is a cylinder, and a driving arm 7 is provided between the output end of the cylinder and the rotating shaft 31. Since the two connected conveying platforms rotate up and down synchronously, the rotation amplitude does not need to be too large to form a channel for conveying materials downward. Correspondingly, the rotation amplitude of the swing arm 3 is small, and the use of a cylinder can meet the requirements, and the cylinder action is more efficient. In order to adapt to the position change of the driving arm 7 when it rotates, the cylinder is arranged on a cylinder seat 8, the main body of the cylinder is rotatably connected to the cylinder seat 8, and the output end of the cylinder is rotatably connected to the driving arm 7.

[0025] In order to ensure the stability of the swing arm movement, an expansion sleeve 32 is provided between the swing arm 3 and the rotating shaft 31 to avoid slipping between the swing arm and the rotating shaft. In order to ensure the stability of the transmission between the swing arm and the connecting conveying platform, connecting shafts 33 are provided at both ends of the swing arm 3, and the connecting rods 4 are rotatably connected at both ends of the connecting shaft 33. The two connecting rods 4 at both ends of the connecting shaft 33 are rotatably connected to the two sides of the connecting conveying platform 1, that is, each connecting conveying platform 1 is pulled and supported by two connecting rods 4. In addition, the vertical width of the swing arm 3 gradually decreases from the middle to the two ends and along the upper and lower sides, that is, the middle part of the swing arm is wider to improve the structural strength, and the width of the two ends gradually decreases to avoid collision with the bottom surface of the support seat 2 during rotation.

[0026] like Figure 3 As shown, in order to save costs, the connecting conveying platform 1 is synchronously connected with the upper conveying line 6, so that the connecting conveying platform is driven by the power of the upper conveying line, thereby saving the driving device and related transmission parts. Specifically, the connecting conveying platform 1 includes a connecting conveying roller 11 and a connecting conveying belt 12, and the upper conveying line 6 includes an upper conveying roller 61 and an upper conveying belt 62. The connecting conveying platform 1 is rotationally connected with the adjacent upper conveying roller 61, and the adjacent connecting conveying rollers 11 and upper conveying rollers 61 are connected by synchronous pulleys 81 and synchronous belts 82. When the connecting conveying platform rotates, the distance between the connecting conveying roller 11 and the upper conveying roller 61 remains unchanged, and a stable transmission relationship can be maintained between the two. Among them, the upper conveying line is a belt conveyor, and its detailed structure is not repeated here.

[0027] The above is only a preferred specific implementation of the utility model, which is a realization method based on the overall concept of the utility model, and the protection scope of the utility model is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
