[0024] Embodiment ①:

[0025] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, An adjustable trough angle idler bracket, comprising an idler bracket 1. At the top of the idler bracket 1, two side struts 2 and two middle brackets 3 are fixedly connected. At the top of the idler bracket 1, there are side idlers 4 and two middle idlers 5. The surface of the middle idler 5 is rotatably sleeved with the two middle brackets 3. The surfaces of the two side idlers 4 are both rotatably sleeved with adjusting seats 6. Inside the adjusting seat 6, two guide grooves 7 are opened. Inside the guide grooves 7, two threaded rods 8 fixedly connected to the side struts 2 are slidably connected. A positioning nut 9 is threadedly connected to the surface of the threaded rod 8. One end of the side idler 4 close to the middle bracket 3 is hinged to the middle bracket 3; at the bottom of the idler bracket 1, there is a base 10. At the top of the base 10, a support frame 11 is fixedly connected. Inside the support frame 11, an adjusting screw 12 is sleeved. A threaded block 13 is threadedly connected to the surface of the adjusting screw 12. On the surface of the threaded block 13, two connecting plates 14 fixedly connected to the idler bracket 1 are fixedly connected. A first bevel gear 15 is fixedly sleeved on the surface of the adjusting screw 12. The first bevel gear 15 meshes with a second bevel gear 16. Inside the second bevel gear 16, a rotating rod 17 is fixedly sleeved; by setting that the two adjusting seats 6 are rotatably sleeved with the two side idlers 4, by hinging the two side idlers 4 to the two middle brackets 3 respectively, by adjusting the position of the adjusting seat 6, and by threadedly connecting the positioning nut 9 and the threaded rod 8 to lock the position of the adjusting seat 6, the inclination angle of the side idler 4 can be adjusted, thereby realizing the adjustment of the trough angle, and further ensuring that the belt will not be flattened. By setting that the rotating rod 17 drives the second bevel gear 16 and the first bevel gear 15 to rotate, by the first bevel gear 15 driving the adjusting screw 12 to rotate, by rotating the adjusting screw 12 clockwise or counterclockwise, the threaded block 13 can be driven to drive the two connecting plates 14 up or down. By the connecting plates 14 moving up, the support frame 11 and the side idler 4 and the middle idler 5 on its top can be pushed up and down, and the fine adjustment of the belt tightness can be realized. Moreover, adjusting the heights of the side idler 4 and the middle idler 5 can also enable the idler bracket to perform conveying work at different heights.

[0026] Further, a through groove 18 is opened inside the support frame 11. The side of the connecting plate 14 away from the adjusting screw 12 does not contact the idler bracket 1. Through the setting of the through groove 18, it is convenient for the connecting plate 14 to move up and down.

[0027] Further, the adjusting screw 12 is rotatably connected to the base 10 through a bearing, and the rotating rod 17 is rotatably connected to the base 10 through a bearing. Through the setting of the bearings, the bearings used by the adjusting screw 12 and the rotating rod 17 both play a role in restricting their rotation at specific positions.

[0028] Further, the bottom of the idler bracket 1 contacts the top of the base 10. One end of the rotating rod 17 penetrates to the outside of the base 10 and is fixedly connected with a turning handle. Through the setting of the rotating rod 17 and the turning handle, it is convenient for the user to rotate the second bevel gear 16 mechanically, so as to enable the second bevel gear 16 to drive the first bevel gear 15 and the adjusting screw 12 to rotate.

[0029] Further, sliding grooves 21 are formed on both sides of the support frame 11, and sliders 19 fixedly connected to the idler bracket 1 are slidably connected inside the sliding grooves 21. Through the arrangement of the sliding grooves 21 and the sliders 19, the up-and-down movement of the support frame 11 is guided.

[0030] Further, an installation groove 20 is formed inside the idler bracket 1, and the first bevel gear 15 and the second bevel gear 16 are both located inside the installation groove 20. Through the arrangement of the installation groove 20, the rotation of the second bevel gear 16 and the first bevel gear 15 is facilitated.

[0031] Brief description of the usage process: During use, take the left side idler 4 as an example;

[0032] First, separate the four positioning nuts 9 and the four threaded rods 8 on one side of the adjusting seat 6 connected to the left side idler 4, then lift one end of the left side idler 4 upward, so that the adjusting seat 6 slides on one side of the side support column 2. At the same time, the guide groove 7 formed inside the adjusting seat 6 will slide on the surface of the threaded rod 8. After adjusting the inclination angle of the side idler 4, connect the removed four positioning nuts 9 to the four threaded rods 8 respectively and rotate and lock them to limit the adjusting seat 6. Then, operate the right side idler 4 as needed to adjust the angle of the right side idler 4.

[0033] If the belt is slightly loose or too tight, the rotating rod 17 can be rotated clockwise to drive the second bevel gear 16 to rotate clockwise, drive the first bevel gear 15 to rotate counterclockwise through the second bevel gear 16, drive the adjusting screw 12 to rotate counterclockwise through the first bevel gear 15, and drive the threaded block 13 to drive the connecting plate 14 and the idler bracket 1 and the side idler 4 and the middle idler 5 on the top of the connecting plate 14 upward, or rotate the rotating rod 17 counterclockwise to drive the second bevel gear 16 to rotate counterclockwise, drive the first bevel gear 15 through the second bevel gear 16 to drive the adjusting screw 12 to rotate clockwise, and drive the threaded block 13 to drive the connecting plate 14, the idler bracket 1, the side idler 4 and the middle idler 5 to move downward.

[0034] By rotating the rotating rod 17 in different reverse directions as described above, the slight looseness and tightness of the belt can be adjusted.

[0035] And by adjusting the height of the idler bracket 1 as described above, the idler bracket can also be used in cooperation with the belt at different heights.

[0036] In summary, the bracket has a simple structure and strong practicability. The bracket has good adjustable performance and is convenient for installation and adjustment. Multiple sets of idler groups at different angles can be used to gradually form the conveyor belt from a flat shape to a trough shape or gradually flatten it from a trough shape with a small-angle transition. The bracket is simple to manufacture and has a low cost. It is suitable for various specifications of belt conveyors and has good adaptability.

[0037] This specific embodiment is only an explanation of the present invention and does not limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
