Description

Technical Field

[0001] The utility model relates to the technical field of trough idlers, in particular to a trough idler with adjustable inclination angle. Background Art

[0002] The function of the idler is to support the weight of the conveyor belt and the materials. The idler must run flexibly and reliably. Reducing the friction between the conveyor belt and the idler plays a key role in the service life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the idler is a small part in the belt conveyor and its structure is not complex, it is not easy to manufacture high-quality idlers.

[0003] The currently widely used trough idler generally includes two side idlers and an intermediate idler. The side idlers and the intermediate idler are tilted upward at a certain angle to form a groove. In the prior art, the side idler frame, the intermediate idler frame and the base are fixed structures, and the angle between the side idlers and the intermediate idler is fixed. However, different belt conveyors have different requirements for the angle of the trough idler. Therefore, this structure can only be used for fixed belt conveyors, with poor versatility and inconvenient use.

[0004] Chinese Patent 202321943675.0 discloses "A Trough Idler Frame", with the publication number CN221092515U. The device includes a base, an intermediate idler, and side idlers. Opposite vertical plates are provided at the top of the base. The intermediate idler is rotatably placed between the two vertical plates. Opposite limit blocks are provided on the side walls of the vertical plates to form a rotating groove. A rotating plate is rotatably connected in the rotating groove.

A clamping plate is provided on the inclined plate, and an adjusting component is provided between the clamping plate and the inclined plate. The side idler is rotatably placed between the clamping plate and the rotating plate. The adjusting component includes a lead screw, an adjusting nut, and a rotating sleeve. The lead screw is threadedly connected to the inclined plate, and nuts threadedly connected to the lead screw are rotatably connected to both the top and bottom of the inclined plate. However, this device has some defects: when adjusting the inclination angle of the inclined plate, it is necessary to adjust the inclination angles of the two inclined plates separately, which is troublesome to operate and may not be able to make the inclination angles of the two side inclined plates the same.

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 The present utility model provides a technical solution: a trough idler with adjustable inclination angle, including a base plate 1 and wing plates 2 symmetrically arranged on both sides of the base plate 1. Idlers 3 are arranged on both the base plate 1 and the wing plates 2. The wing plates 2 are hinged at the ends of the base plate 1. The base plate 1 is fixedly connected to a support plate 4. Symmetrically arranged sliders 41 are slidably connected to the support plate 4. A support column 42 is hinged to the slider 41, and the upper end of the support column 42 is hinged to the wing plate 2. A driving component for driving the relative movement of the sliders 41 is arranged on the support plate 4.

[0026] The driving component includes a bidirectional lead screw 43 threaded through the slider 41, and a shaft seat 44 sleeved on the bidirectional lead screw 43. An installation groove matching the bidirectional lead screw 43 is opened on the support plate 4. The shaft seat 44 is fixedly connected to the support plate 4. A hand wheel 45 is fixedly connected to the end of the bidirectional lead screw 43.

[0027] When the idler 3 is worn or damaged, in order to facilitate the replacement of the idler 3, the idler 3 includes a rotating shaft 31 passing through its interior. Both ends of the rotating shaft 31 are inserted into the limit plates 51. The upper end of the limit plate 51 is a U-shaped structure matching the rotating shaft 31. Oppositely arranged clamping plates 52 are fixedly connected to the ends of the rotating shaft 31. The upper end of the limit plate 51 is inserted into the gap between the clamping plates 52. The limit plates 51 are fixedly connected to both the base plate 1 and the wing plate 2.

[0028] A positioning pin 6 passes through the upper end of the limit plate 51, and a positioning hole matching the positioning pin 6 is opened on the rotating shaft 31.

[0029] A clamping plate 71 is fixedly connected to the positioning pin 6. A return spring 72 is arranged between the clamping plate 71 and the outer side wall of the limit plate 51. The head end of the return spring 72 is fixedly connected to the clamping plate 71, and the tail end of the return spring 72 is fixedly connected to the outer side wall of the limit plate 51. When the return spring 72 is not deformed, the positioning pin is in a state of being inserted into the rotating shaft 31. A protective shell 73 is sleeved on the positioning pin 6, and the protective shell 73 is fixedly connected to the limit plate 51.

[0030] Scale lines are arranged on the outer side wall of the support plate 4, which is convenient for the staff to record the moving distance of the slider according to the scale lines, and thus facilitate the adjustment of the wing plates of adjacent devices to the same inclination angle.

[0031] When the device is in use, first, the staff adjusts the inclination angle of the wing plate 2. The staff rotates the handwheel 45, and the bidirectional lead screw 43 rotates accordingly. Under the action of the thread, the sliders 41 approach or move away from each other, thereby making the inclination angle of the wing plate 2 larger or smaller. After the inclination angle of the wing plate 2 is adjusted, the staff installs the idler 3. The staff places the rotating shaft 31 of the idler 3 into the U-shaped structure at the upper end of the limit plate 51. The upper end of the limit plate 51 is inserted into the gap between the clamping plates 52. The staff pulls the positioning pin 6 to make the positioning pin 6 contract. After the rotating shaft 31 is placed into the U-shaped structure at the upper end of the limit plate 51, the staff releases the positioning pin 6. Under the action of the return spring 72, the positioning pin 6 is inserted into the positioning hole in the rotating shaft 31, and the installation of the idler 3 is completed. Then the staff installs the device into the conveyor.
