Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and specifically to a large-angle variable tilt trough type idler group. Background Technology

[0002] Idler assemblies on belt conveyors are components used to support the conveyor belt and the materials carried on it, ensuring the stable operation of the conveyor belt. Depending on their function, idler assemblies can be divided into various types such as trough idler assemblies, trough forward-inclined idler assemblies, and adjustable trough angle idler assemblies. They are installed on belt conveyors and play different roles.

[0003] The side roller inclination angle of traditional trough roller sets is fixed, usually a fixed angle between 10° and 35°. It cannot be dynamically adjusted according to material characteristics (such as flowability and angle of repose), which leads to easy material spillage, belt wear, or increased energy consumption. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a large-angle variable tilt trough type idler roller group.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a large-angle variable tilt trough-type idler roller assembly, including a base frame, a central idler roller, and side idler roller assemblies. The central idler roller is horizontally installed in the middle of the base frame via a support plate, and the side idler roller assemblies are arranged symmetrically on both sides of the base frame. The side idler roller assembly includes a side idler roller and an adjustable support arm. The side idler roller is rotatably mounted on the adjustable support arm, and the lower part of the adjustable support arm is bolted to the base frame. The side of the base frame and the lower part of the adjustable support arm are provided with multiple bolt holes. By using bolts to install the adjustable support arm through different bolt holes, the side idler roller can form different tilt angles relative to the base frame.

[0006] In the above technical solution, by providing multiple bolt holes on the side of the base frame and the lower part of the adjustable support arm, and installing the adjustable support arm by passing bolts through different bolt holes, the side roller can form different inclination angles relative to the base frame, and the stability of the side roller at different inclination angles can also be ensured.

[0007] Furthermore, the base frame has one elongated through-hole for bolts, while the remaining bolt holes are arranged at linear intervals. The adjustable support arm has one separate bolt hole, and the remaining bolt holes are spaced apart and form at least one arc array. This design makes the tilt angle adjustment of the side rollers orderly and predictable.

[0008] Preferably, the multiple bolt holes on the adjustable support arm are spaced apart and form two parallel arc arrays.

[0009] Preferably, the center idler roller and the two side idler roller assemblies are arranged in a triangular pattern. This prevents the side idler rollers from interfering with the center idler roller when adjusting their angle, thereby increasing the tilt angle adjustment range of the side idler rollers.

[0010] Furthermore, height adjustment mechanisms are installed at both ends of the base frame, and the height adjustment mechanisms include adjustment support plates and adjustment screws. As the inclination angle of the side idlers changes, the theoretical center line of the conveyor belt surface will also change. In order to keep the center line of the conveyor belt surface consistent with other types of idler groups, the height of the base frame can be adjusted by the height adjustment mechanisms.

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] It should be noted in advance that, in this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] like Figures 1 to 6 As shown, a large-angle variable tilt trough-type idler assembly includes a base frame 1, a central idler 2, and side idler assemblies. The central idler 2 is horizontally mounted in the middle of the base frame 1 via a support plate and a bracket. The side idler assemblies are arranged symmetrically on both sides of the base frame 1. The side idler assemblies include side idlers 3 and adjustable support arms 4. The side idlers 3 are rotatably mounted on the adjustable support arms 4 via a bracket. The lower part of the adjustable support arms 4 is bolted to the base frame 1. The side of the base frame 1 and the lower part of the adjustable support arms 4 are provided with multiple bolt holes. By using bolts to install the adjustable support arms 4 through different bolt holes, the side idlers 3 can form different tilt angles relative to the base frame 1, and the stability of the side idlers 3 at different tilt angles can be ensured.

[0027] like Figure 1 , 3 As shown in Figure 4, the base frame 1 has one elongated bolt through hole, and the remaining bolt through holes are arranged in a straight line at intervals. The adjustable support arm 4 has one bolt through hole set separately, and the remaining bolt through holes are spaced apart and form two parallel arc arrays. This design makes the tilt angle adjustment of the side roller 3 orderly and predictable.

[0028] like Figure 2 As shown, the center idler roller 2 and the two side idler roller assemblies are arranged in a triangular pattern. This ensures that the side idler rollers 3 will not interfere with the center idler roller 2 when adjusting their angle, thus allowing for a wider range of tilt angle adjustment for the side idler rollers 3. Figures 7 to 11 As shown, multiple angles can be selected and set between 10.5° and 75.5°.

[0029] like Figure 1 , 6As shown, height adjustment mechanisms 5 are installed at both ends of the base frame 1. The height adjustment mechanism 5 includes an adjustment support plate 5a and an adjustment screw 5b. As the inclination angle of the side idler rollers 3 varies, the theoretical center line of the conveyor belt surface will also change. In order to keep the center of the conveyor belt surface consistent with other types of idler roller groups, the height of the base frame 1 can be adjusted by adjusting the height of the base frame 1 through the height adjustment mechanism 5.

[0030] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.

[0031] To facilitate understanding by those skilled in the art of the improvements of this invention over the prior art, some of the accompanying drawings and descriptions have been simplified, and for clarity, some other elements have been omitted from this application. Those skilled in the art should realize that these omitted elements may also constitute the content of this invention.
