Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, specifically to a high-efficiency friction-reducing mechanism for the transition section between the head and tail of a scraper conveyor. Background Technology

[0002] Scraper conveyors are material conveying equipment commonly used in heavy industry, mainly for conveying cement, ore, coal and other bulk materials. They consist of a body, transmission device, scraper conveyor chain, tensioning device, guide rollers, and cleaning device.

[0003] According to the utility model disclosed in patent authorization announcement number CN211686924U, the scraper conveyor includes a housing, an internal sprocket, a scraper mechanism, and a baffle plate. The internal sprocket is rotatably disposed in the housing. The scraper mechanism is supported on two internal sprockets located at both ends. One end of the baffle plate is disposed on the inner surface of the housing and extends toward the internal sprocket.

[0004] The transition section between the head and tail of a scraper conveyor is an important part for load and thrust transmission. Because the material changes direction of linear movement in this area, the friction and wear are relatively large, and it is prone to damage after long-term use. Utility Model Content

[0005] The purpose of this utility model is to provide an efficient friction reduction mechanism for the transition section between the head and tail of a scraper conveyor, which solves the problem that the friction and wear of the transition section between the head and tail of the scraper conveyor are relatively large, and that it is easy to be damaged during long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency friction-reducing mechanism for the transition section between the head and tail of a scraper conveyor, comprising a mounting frame, a roller rotatably connected inside the mounting frame, a mounting block slidably connected inside the mounting frame, a rotating shaft fixedly connected to the side of the mounting block away from the mounting frame, the rotating shaft being connected to the roller via a bearing, a sliding rod fixedly connected to the lower end of the mounting block, the sliding rod being slidably connected to the mounting frame, a damping block fixedly connected to the lower end of the sliding rod, the damping block being slidably connected to the mounting frame, a spring being provided inside the mounting frame, air holes being provided on the mounting frame, and a limit mechanism being provided on the mounting frame.

[0007] Preferably, a limiting ring is fixedly connected inside the mounting bracket, and a sliding rod is slidably connected inside the limiting ring. The limiting ring is designed to limit the movement of the sliding rod.

[0008] Preferably, one end of the spring contacts the mounting bracket, and the other end of the spring contacts the damping block. Through the design of the spring, the damping block can be driven to reset.

[0009] Preferably, the limiting mechanism includes a limiting plate. The outer side of the mounting frame contacts the limiting plate. A plug is fixedly connected to the side of the limiting plate near the mounting frame. The plug is slidably connected to the air hole. A threaded rod is rotatably connected inside the limiting plate. The threaded rod is threadedly connected to the mounting frame. A retaining ring is fixedly connected to the outer side of the threaded rod. The retaining ring is rotatably connected to the limiting plate and contacts the mounting frame. By rotating a knob, the knob drives the threaded rod to rotate, causing the threaded rod to move threadedly with the mounting frame. This causes the threaded rod to move the limiting plate, which in turn moves the plug, allowing the plug to slide out of the air hole and activate the roller's buffer function.

[0010] Preferably, a guide rod is fixedly connected to the side of the limiting plate near the mounting frame. The guide rod is slidably connected to the mounting frame. The design of the guide rod can limit the position of the limiting plate.

[0011] Preferably, a knob is fixedly connected to the end of the threaded rod away from the mounting bracket. The knob contacts the limiting plate, and the design of the knob allows the threaded rod to be rotated easily.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by incorporating rollers, enables the scraper to rotate smoothly, thereby reducing the friction and wear of the scraper conveyor. Furthermore, by incorporating damping blocks, springs, and other components, the rollers can provide a buffering effect, making the scraper rotation smoother. This solves the problem of high friction and wear in the transition section between the head and tail of the scraper conveyor, which can easily lead to damage during long-term use.

[0014] 2. This utility model, by setting up components such as a limiting plate, a plug, and a threaded rod, allows the threaded rod to rotate, causing it to move in a threaded motion with the mounting bracket. This, in turn, causes the plug on the limiting plate to slide into the air hole, thereby turning off the roller's shock absorption function. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 A high-efficiency friction-reducing mechanism for the transition section between the head and tail of a scraper conveyor includes a mounting frame 1. A roller 2 is rotatably connected inside the mounting frame 1. A mounting block 3 is slidably connected inside the mounting frame 1. A rotating shaft 31 is fixedly connected to the side of the mounting block 3 away from the mounting frame 1. The rotating shaft 31 is connected to the roller 2 through a bearing. A sliding rod 32 is fixedly connected to the lower end of the mounting block 3. The sliding rod 32 is slidably connected to the mounting frame 1. A limit ring 33 is fixedly connected inside the mounting frame 1. The sliding rod 32 is slidably connected inside the limit ring 33. Through the design of the limit ring 33, the sliding rod 32 can be limited.

[0024] Please see Figure 2-6 A damping block 34 is fixedly connected to the lower end of the slide rod 32. The damping block 34 is slidably connected to the mounting frame 1. A spring 35 is provided inside the mounting frame 1. One end of the spring 35 contacts the mounting frame 1, and the other end of the spring 35 contacts the damping block 34. Through the design of the spring 35, the damping block 34 can be driven to reset. An air hole 36 is provided on the mounting frame 1, and a limit mechanism 4 is provided on the mounting frame 1.

[0025] Please see Figure 2-6The limiting mechanism 4 includes a limiting plate 41. The outer side of the mounting bracket 1 contacts the limiting plate 41. A plug 42 is fixedly connected to the side of the limiting plate 41 near the mounting bracket 1. The plug 42 is slidably connected to the air hole 36. A guide rod 43 is fixedly connected to the side of the limiting plate 41 near the mounting bracket 1. The guide rod 43 is slidably connected to the mounting bracket 1. The guide rod 43 can limit the limiting plate 41 through its design. A threaded rod 44 is rotatably connected inside the limiting plate 41. The threaded rod 44 is threadedly connected to the mounting bracket 1. A retaining ring 45 is fixedly connected to the outer side of the threaded rod 44. Ring 45 is rotatably connected to limiting plate 41, retaining ring 45 is in contact with mounting bracket 1, and a knob 46 is fixedly connected to the end of threaded rod 44 away from mounting bracket 1. Knob 46 is in contact with limiting plate 41. Through the design of knob 46, threaded rod 44 can be easily rotated. By rotating knob 46, the knob 46 drives threaded rod 44 to rotate, causing threaded movement between threaded rod 44 and mounting bracket 1. This causes threaded rod 44 to drive limiting plate 41 to move, which in turn causes limiting plate 41 to drive plug 42 to move, allowing plug 42 to slide out of air hole 36, thus activating the buffer function of roller 2.

[0026] The specific implementation process of this utility model is as follows: When in use, by rotating the knob 46, the knob 46 drives the threaded rod 44 to rotate, causing the threaded rod 44 to move with the mounting bracket 1, thereby causing the threaded rod 44 to move the limiting plate 41, which in turn causes the limiting plate 41 to move the plug 42, allowing the plug 42 to slide out of the air hole 36, thus opening the buffer function of the roller 2.

[0027] When the scraper plate flips, the roller 2 rotates to assist the scraper plate in flipping, causing the scraper plate to drive the roller 2 to move. The roller 2 then drives the mounting block 3 to move via the rotating shaft 31. The mounting block 3 drives the slide rod 32 to slide within the limiting ring 33. The slide rod 32 drives the damping block 34 to move, causing the damping block 34 to compress the spring 35 and squeeze the gas in the mounting frame 1 out of the air hole 36. This provides a buffering effect on the roller 2, making the scraper plate more stable when flipping and reducing the wear of the scraper conveyor.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
