Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor equipment, specifically a belt tail sweeper for conveyor belts in a conveyor belt chute. Background Technology

[0002] In the process of coal mining and transportation, belt conveyors are the main transportation equipment. Due to factors such as the stickiness of coal and the conveying angle, some material often remains at the tail of the belt. If it is not cleaned in time, it will not only cause waste of resources, but may also cause belt deviation, increased wear, or even equipment failure due to the accumulation of residual coal, affecting production efficiency and safety.

[0003] Existing belt tail sweeping devices mostly use a fixed-angle scraper structure, which has the following shortcomings: the sweeping angle is fixed and cannot be flexibly adjusted according to the wear of the belt, the amount of coal residue, and other working conditions, which easily leads to incomplete sweeping or excessive wear of the scraper; the scrapers are mostly unidirectional fixed structures, and after long-term use, they are prone to coal accumulation, requiring regular manual cleaning, which increases maintenance costs, and the adjustment mechanism lacks a buffer design, which easily generates impact during operation, leading to increased equipment vibration and shortening service life. In view of this, we propose a belt tail sweeper in the belt conveyor to solve the existing problems. Utility Model Content

[0004] The purpose of this utility model is to provide a belt conveyor tail sweeper to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a belt conveyor tail sweeper, comprising a fixed plate, a belt, an adjusting mechanism, a sweeping mechanism, a belt shaft, and a baffle. Two sets of fixed plates are symmetrically arranged, and a belt shaft is provided on one side of the fixed plate, with a belt mounted on the belt shaft. Gear-driven adjusting mechanisms are provided on both sides of the fixed plate. The adjusting mechanism includes a rotating shaft, a threaded guide mechanism is provided on the rotating shaft, and a baffle is provided on one side of the rotating shaft and the guide mechanism.

[0006] Preferably, the adjustment mechanism includes a rotating shaft, a swing frame, a transmission wheel, a telescopic cylinder, a mounting plate, a guide member, a transmission rack, a movable member, a fixed rod, a guide block, a return spring, and a fixed seat. Each fixed plate is provided with a swing frame, and the swing frames are movably connected to each other by a rotating shaft. A transmission wheel is provided inside the swing frame, and a mounting plate is fixedly connected to one side of the fixed plate. A telescopic cylinder is fixedly connected to one side of the mounting plate. The output end of the telescopic cylinder passes through the mounting plate and is fixedly connected to a transmission rack. The transmission rack and the transmission wheel mesh with each other.

[0007] Preferably, a guide member is fixedly connected to the swing frame, and a movable member is movably connected to one side of the fixed plate. A fixed rod is fixedly connected to the movable member, and a fixed seat is fixedly connected to the side of the fixed rod away from the movable member. The fixed rod is located on the guide member, and a guide block is fixedly connected to one side of the guide member. A return spring is sleeved on the fixed rod between the guide block and the fixed seat.

[0008] Preferably, the coal sweeping mechanism includes a mounting base, a drive motor, a coal sweeping block, a threaded rod, and a guide rod. Mounting bases are symmetrically arranged on the rotating shaft, and guide rods are arranged between the mounting bases. A threaded rod is movably connected to one side of the guide rod, and a drive motor is embedded in the mounting base. The output end of the drive motor is fixedly connected to the threaded rod, and a coal sweeping block is movably connected to the threaded rod and the guide rod.

[0009] Preferably, the coal sweeping block and the baffle cooperate with each other, the drive motor is electrically connected to an external power source, and the baffle and the belt cooperate with each other.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. When the telescopic cylinder is supplied with air, the transmission rack will move synchronously with the cylinder's movement. The transmission rack and the transmission wheel inside the swing frame will form a gear meshing relationship. The linear motion of the rack is converted into the rotational motion of the transmission wheel, which will drive the entire swing frame to rotate on the fixed plate, thereby changing the tilt angle of the swing frame. During the rotation of the swing frame, the guide component fixed on it will move synchronously. The guide component is sleeved on the fixed rod. When the angle of the swing frame changes, the guide component will squeeze or stretch the return spring to avoid the adjustment action being too violent and enhance the stability of the mechanism.

[0012] 2. After the drive motor is connected to the external power supply, it starts and its output directly drives the threaded rod to rotate. The coal sweeping block is connected to both the threaded rod and the guide rod. When the threaded rod rotates, the threaded transmission is converted into the linear motion of the coal sweeping block, ensuring that it moves smoothly along a fixed trajectory. Through the forward and reverse control of the drive motor, the coal sweeping block can achieve reciprocating motion. The baffle is close to the surface of the belt and can scrape off residual coal that has not been completely cleaned from the edge of the belt. At the same time, by starting the drive motor, the coal sweeping block is guided to clean the baffle, and the cleaned coal falls in the designated direction. Attached Figure Description

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

The fixed plate 1 is symmetrically arranged in two sets, and a belt shaft 5 is arranged on one side of the fixed plate 1. The belt shaft 5 is equipped with a belt 2. Gear-driven adjusting mechanisms 3 are arranged on both sides of the fixed plate 1. The adjusting mechanism includes a rotating shaft 301, a threaded guide mechanism is arranged on the rotating shaft 301, and a baffle 6 is arranged on one side of the rotating shaft 301 and the guide mechanism.

Each fixed plate 1 is provided with a swing frame 302, and the rotating shaft 301 is movably connected between the swing frames 302. The transmission wheel 303 is provided inside the swing frame 302. The mounting plate 305 is fixedly connected to one side of the fixed plate 1, and the telescopic cylinder 304 is fixedly connected to one side of the mounting plate 305. The output end of the telescopic cylinder 304 passes through the mounting plate 305 and is fixedly connected to the transmission rack 307. The transmission rack 307 and the transmission wheel 303 mesh with each other.

[0021] In an optional embodiment, a guide member 306 is fixedly connected to the swing frame 302, and a movable member 308 is movably connected to one side of the fixed plate 1. A fixed rod 309 is fixedly connected to the movable member 308, and a fixed seat 312 is fixedly connected to the side of the fixed rod 309 away from the movable member 308. The fixed rod 309 is located on the guide member 306, and a guide block 310 is fixedly connected to one side of the guide member 306. A return spring 311 is sleeved on the fixed rod 309 between the guide block 310 and the fixed seat 312.

[0022] When the telescopic cylinder 304 is supplied with air, the transmission rack 307 will move synchronously with the cylinder's movement. The transmission rack 307 and the transmission wheel 303 inside the swing frame 302 form a gear meshing relationship. The linear motion of the rack is converted into the rotational motion of the transmission wheel 303, which will drive the entire swing frame 302 to rotate on the fixed plate 1, thereby changing the tilt angle of the swing frame 302. During the rotation of the swing frame 302, the guide member 306 fixed on it will move synchronously. The guide member 306 is sleeved on the fixed rod 309. When the angle of the swing frame 302 changes, the guide member 306 will squeeze or stretch the return spring 311 to avoid the adjustment action being too violent and enhance the stability of the mechanism.

[0023] In an optional embodiment, the coal sweeping mechanism 4 includes a mounting base 401, a drive motor 402, a coal sweeping block 403, a threaded rod 404, and a guide rod 405. The mounting bases 401 are symmetrically arranged on the rotating shaft 301, and the guide rods 405 are arranged between the mounting bases 401. The threaded rod 404 is movably connected to one side of the guide rod 405, and the drive motor 402 is embedded in the mounting base 401. The output end of the drive motor 402 is fixedly connected to the threaded rod 404, and the coal sweeping block 403 is movably connected to the threaded rod 404 and the guide rod 405.

[0024] In an optional embodiment, the coal sweeping block 403 and the baffle 6 cooperate with each other, the drive motor 402 is electrically connected to an external power source, and the baffle 6 and the belt 2 cooperate with each other.

[0025] After the drive motor 402 is connected to the external power supply, it starts and its output directly drives the threaded rod 404 to rotate. The coal sweeping block 403 is connected to both the threaded rod 404 and the guide rod 405. When the threaded rod 404 rotates, the threaded transmission is converted into linear motion of the coal sweeping block 403, ensuring that it moves smoothly along a fixed trajectory. Through the forward and reverse control of the drive motor 402, the coal sweeping block 403 can achieve reciprocating motion. The baffle 6 is close to the surface of the belt 2 and can scrape off residual coal that has not been completely cleaned from the edge of the belt 2. At the same time, by starting the drive motor 402, the coal sweeping block 403 is guided to clean the baffle 6, and the cleaned coal falls in the designated direction.

[0026] The working principle of this utility model is as follows: When the telescopic cylinder 304 is supplied with air, the transmission rack 307 will move synchronously with the cylinder. The transmission rack 307 and the transmission wheel 303 inside the swing frame 302 form a gear meshing relationship. The linear motion of the rack is converted into the rotational motion of the transmission wheel 303, which will drive the entire swing frame 302 to rotate on the fixed plate 1, thereby changing the tilt angle of the swing frame 302. During the rotation of the swing frame 302, the guide member 306 fixed on it will move synchronously. The guide member 306 is sleeved on the fixed rod 309. When the angle of the swing frame 302 changes, the guide member 306 will squeeze or stretch the return spring 311 to avoid the adjustment action being too violent and enhance the stability of the mechanism.

[0027] After the drive motor 402 is connected to the external power supply, it starts and its output directly drives the threaded rod 404 to rotate. The coal sweeping block 403 is connected to both the threaded rod 404 and the guide rod 405. When the threaded rod 404 rotates, the threaded transmission is converted into linear motion of the coal sweeping block 403, ensuring that it moves smoothly along a fixed trajectory. Through the forward and reverse control of the drive motor 402, the coal sweeping block 403 can achieve reciprocating motion. The baffle 6 is close to the surface of the belt 2 and can scrape off residual coal that has not been completely cleaned from the edge of the belt 2. At the same time, by starting the drive motor 402, the coal sweeping block 403 is guided to clean the baffle 6, and the cleaned coal falls in the designated direction.
