Description

Technical Field

[0001] The invention relates to the field of coal mining, and in particular to a belt conveyor for conveying ore in coal mining. Background Art

[0002] During coal mining, in order to transport the mined ore to the processing site, a belt conveyor is needed to transport the ore. Using a belt conveyor to transport the ore can quickly transport the ore to the designated location, effectively saving manpower and improving production efficiency.

[0003] At present, there are various types of belt conveyors for ore transportation, but the following problems are common: first, the individual ores are of different sizes. During transportation, the large individual ores at the top have a small contact area with the small individual ores, which are easy to roll down and lack crushing measures. In addition, when transporting the ore, the belt conveyor has a simple unloading structure and lacks a transition buffer structure. On the one hand, it cannot ensure that the ore is evenly distributed in the middle of the conveyor belt after falling, and will not be distributed on both sides. In addition, the direct fall of the ore has too much impact on the conveyor belt, which can easily cause damage to the conveyor belt and seriously affect the service life of the conveyor belt. During the ore transportation process, the ores collide with each other to generate dust. There is a lack of better treatment measures, which can easily affect the transportation environment and sanitation and bring health hazards. Summary of the invention

[0010] Optionally, the adjustment assembly includes a threaded sleeve, and both ends of the threaded sleeve are meshedly connected with screws, and the ends of the two screws that are away from each other are connected with sliders, and a connecting bearing is installed on the inner side of the slider.

[0011] Optionally, the slider is slidably connected in the slide groove, and the thread directions of the two screw surfaces are opposite.

[0012] Optionally, a movable groove is provided on the top of the receiving plate, and two receiving slide plates are installed on the inner side of the movable groove. A U-shaped support seat is installed on the top of the receiving slide plate, and a driving motor is installed on the inner side of the U-shaped support seat.

[0013] Optionally, the power shaft of the driving motor passes through a connecting bearing on the inner side of the slider and is connected to one end of the squeezing roller, and a plurality of cones are arranged on the outer side of the squeezing roller.

[0014] Optionally, an adjustment slot plate is also installed inside the discharge box at the other end of the two squeezing rollers, and an adjustment component is also provided inside the adjustment slot plate, and the other end of the squeezing roller is connected to the connecting bearing on the inner side of the slider in the adjustment component.

[0015] Optionally, the opposite ends of the two movable plates are both arranged in an arc shape, and the opposite ends of the two movable plates are located directly below the center line between the two squeezing rollers.

[0016] Beneficial effects of the present invention:

[0017] 1. The present invention sets a squeezing roller. After the ore enters the discharge box, it first passes through the squeezing roller. The larger ore can be squeezed by the squeezing roller to reduce the size of the large individual ore, thereby avoiding the situation in which the ore is too large and the contact area with the small individual ore is small, which can easily cause the ore to roll and fall during transportation.

[0018] 2. By setting an adjustment slot plate and installing an adjustment component in the adjustment slot plate, in conjunction with a receiving plate, the two screws are driven to move relative to each other by rotating the threaded sleeve, thereby adjusting the spacing between the two sliders. Since the bearing in the slider is connected to the power shaft of the drive motor, the drive motor can be driven to move. The drive motor uses a U-shaped support seat to move in a moving slot opened on the receiving plate using a receiving slide, so that adaptive adjustments can be made according to the movement of the drive motor. The power shaft of the drive motor is connected to the extrusion roller, and the other end of the extrusion roller is also connected to the slide slot through a slider, so that the spacing between the two extrusion rollers can be adjusted, which is suitable for the use of ores of different sizes.

[0019] 3. By setting up the unloading assembly, after the ore passes through the squeezing roller, it falls onto the two movable plates. The movable plates are subjected to pressure and turn down under the rotation of the rotating shaft seat. At the same time, the spring rod is squeezed, and the two movable plates open to discharge the ore downward, so that the ore can be concentrated and discharged downward from the middle position inside the unloading box, ensuring that the ore can be discharged downward from the unloading cavity. On the one hand, it can ensure that the ore will not fall to the edge of the conveyor belt during discharge, further preventing the ore from rolling down. On the other hand, the movable plates are used for transition buffering to prevent the ore from falling directly onto the conveyor belt and causing damage to it, effectively protecting the conveyor belt and increasing its service life.

[0020] 4. By setting up an exhaust fan in conjunction with the installation frame, after the ore falls from between the movable plates and collides with each other to generate dust, the exhaust fan will suck in the dusty air and discharge it from the air guide cavity, and install a cloth bag in the circular groove opened on the inner side of the installation frame. Then, the four bolts are screwed until the arc plate fits the outer side of the cloth bag to fix the cloth bag, and the cloth bag is used to filter the dust. On the one hand, it facilitates the installation of the cloth bag, and on the other hand, it effectively reduces the impact of dust generated by collision during the transportation of ore on the air environment, reduces the amount of dust in the ore transportation environment, improves the hygiene of the ore transportation environment, and reduces dust pollution.

[0041] As a technical optimization solution of the present invention, the opposite ends of the two movable plates 21 are both arranged in an arc shape, and the opposite ends of the two movable plates 21 are located directly below the center line between the two squeezing rollers 11.

[0042] When the present invention is in use, firstly, the ore to be transported is put into the middle of the unloading frame 7, and the ore enters the interior of the unloading box 6 from the unloading frame 7, and first passes between the two squeezing rollers 11, and the small individual ore passes between the two squeezing rollers 11. The two squeezing rollers 11 rotate relatively under the drive of the two driving motors 25, and the large individual ore is squeezed by the two squeezing rollers 11 to become smaller, and then falls from the two squeezing roller 11 brackets, and the ore falls onto the two unloading components 12, and the ore falls onto the two movable plates 21. The movable plates 21 are subjected to pressure and turn down under the rotation of the rotating shaft seat 22. At the same time, the spring rod 23 is squeezed, and the space between the two movable plates 21 is opened to discharge the ore downward, and then the exhaust fan 14 in the installation groove 13 is used to suck in the air with dust in the unloading box 6 and introduce it into the air guide cavity 15, and the circular groove 17 opened on the inner side of the installation frame 16 A cloth bag is installed inside, and then four bolts 19 are screwed until the arc plate 20 fits with the outer side of the cloth bag to fix the cloth bag.
