Description

Technical Field

[0001] The present invention relates to the technical field of coal mines, and particularly to a feeding device for a coal mine conveyor. Background Art

[0002] For a belt conveyor used in coal mine transportation, when large pieces of coal with sharp edges are directly dumped onto the receiving section, the sharp edges of the coal pierce into the belt, and the belt will be torn due to driving tension.

[0003] In the prior art, the feeding method of the belt conveyor mostly uses a fixed feeding hopper. Large pieces of coal and powdered coal are sent into the feeding hopper together, and then directly hit the belt from the feeding hopper. Moreover, the feeding hoppers in the prior art are all fixed. The higher the height of the feeding hopper, the greater the gravity hitting the belt, and the easier it is to cause damage to the belt. Summary of the Invention

[0011] Further, the belt transmission assembly includes a pulley A which is fixedly connected to the worm gear. The pulley A is arranged on the rotating shaft A and outside the worm gear. A pulley B is arranged on the rotating shaft B, and a synchronous belt is arranged between the pulley B and the pulley A.

[0012] Further, the feeding mechanism includes a feeding hopper with an inclined bottom. A limiting component is arranged at the discharging end of the feeding hopper. When coal enters the feeding hopper, it slides obliquely towards the limiting component.

[0013] Further, the feeding hopper includes side plates A, B and a side plate C arranged between the left sides of the side plates A and B. The side plates A and B have the same structure. A pedestal is provided at the upper end of the side plate A and sinks downward. The bottom of the side plate A is inclined.

[0014] Further, the limiting component includes a cover plate. A hanging plate is arranged between the pedestals of the side plates A and B. A fixed seat is arranged on the hanging plate.

[0016] Advantages of the present invention:

[0017] 1. The swing mechanism in the present invention can adjust the height of the feeding hopper. After the coal enters the feeding hopper, it slides obliquely down from the bottom plate onto the belt conveying mechanism, effectively solving the problem that the coal hitting the belt conveying mechanism damages the belt and causes the belt conveying mechanism to stop running.

[0018] 2. The main function of the belt conveying mechanism is to transport coal. The feeding mechanism mainly places the coal in the coal mine onto the belt conveying mechanism. The feeding mechanism can prevent the pulverized coal in the coal from splashing everywhere and also plays a role in dust prevention. The swing mechanism can adjust the height of the feeding mechanism, effectively reducing the impact force of the weight of the coal on the belt in the belt conveying mechanism. The driving mechanism provides a constant power source for the swing of the swing mechanism.

[0019] 3. By setting the swing assembly A and the swing assembly B, it can ensure that the feeding mechanism swings smoothly. After the feeding mechanism is adjusted to the appropriate height, the worm and worm gear transmission assembly has a self-locking function, and the belt transmission assembly can ensure that the swing assembly A and the swing assembly B swing synchronously and in the same direction.

[0020] 4. The swing rod A and the swing rod B rotate with the rotation of the rotating shaft A, and the swing rod C and the swing rod D rotate with the rotation of the rotating shaft B.

[0021] 5. Start the motor. The output shaft of the motor rotates, driving the worm to rotate. The worm meshes with the worm gear, so the worm gear rotates. Since the worm gear is arranged on the rotating shaft A, the rotating shaft A rotates, and then drives the swing rod A and the swing rod B to rotate synchronously around the axis of the rotating shaft A. Among them, the worm and worm gear transmission assembly is adopted, and the worm has a self-locking function, which can prevent the feeding hopper from swinging left and right when feeding materials into the feeding hopper.

[0022] 6. Since the pulley A is fixedly arranged on the front side of the worm gear, the rotation of the worm gear drives the pulley A to rotate synchronously. Through the synchronous belt, the pulley B is driven to rotate. Since the pulley B is arranged on the rotating shaft B, the swing rod C and the swing rod D on the rotating shaft B rotate synchronously.

[0023] 7. When coal and pulverized coal are simultaneously placed into the feeding hopper, since the bottoms of side plate A and side plate B are both inclined, the bottom plate is also inclined. The coal and pulverized coal slide on the inclined bottom plate. When they slide to the limiting component, they are blocked by the cover plate, reducing the impact force of the coal and pulverized coal sliding down and being able to reduce the impact force of the coal and pulverized coal on the belt.

[0032] To clearly illustrate the technical features of this solution, the following elaborates on this solution through specific embodiments.

[0033] See Figure 1, A feeding device for a coal mine conveyor, including a feeding mechanism 2 arranged at the receiving section of the belt conveying mechanism 1. The main function of the belt conveying mechanism is to transport coal, and the feeding mechanism is mainly to place the coal in the coal mine on the belt conveying mechanism. The feeding mechanism can prevent the coal powder in the coal from splashing everywhere and also play a role in dust prevention. A swinging mechanism 3 is arranged at the bottom of the feeding mechanism 2. One end of the swinging mechanism 3 is pivotally connected to the feeding mechanism 2, and the other end is pivotally connected to the frame 11 of the belt conveying mechanism 1. The swinging mechanism can adjust the height of the feeding mechanism and effectively reduce the impact force of the weight of the coal on the belt in the belt conveying mechanism. A driving mechanism 4 is arranged on the swinging mechanism 3, and the driving mechanism 4 swings left and right to adjust the distance between the feeding mechanism 2 and the belt conveying mechanism 1. The driving mechanism provides a constant power source for the swinging of the swinging mechanism.

[0034] See Figure 2 and Figure 4 , The swinging mechanism 3 includes a swinging component A31 and a swinging component B32. The driving mechanism 4 includes a worm and worm gear transmission component 41 and a belt transmission component 42. The worm and worm gear transmission component 41 is arranged on the swinging component A31, and the belt transmission component 42 is arranged between the swinging component A31 and the swinging component B32.

[0035] Setting the swinging component A and the swinging component B can ensure that the feeding mechanism can swing smoothly. When the feeding mechanism is adjusted to the appropriate height, the worm and worm gear transmission component has a self-locking function, and the belt transmission component can ensure that the swinging component A and the swinging component B swing synchronously and in the same direction.

[0036] See Figure 3 , The swinging component A31 includes a rotating shaft A311. The rotating shaft A311 penetrates through the frames 11 on the front and rear sides of the belt conveying mechanism 1. One end of the rotating shaft A311 is provided with a swinging rod A312, and the swinging rod A312 is arranged outside the frame 11 on the front side of the belt conveying mechanism 1. The other end of the rotating shaft A311 is provided with a swinging rod B313, and the swinging rod B313 is arranged outside the frame 11 on the rear side of the belt conveying mechanism 1.

[0037] See Figure 3 , The swinging component B32 includes a rotating shaft B321. The rotating shaft B321 penetrates through the frames 11 on the front and rear sides of the belt conveying mechanism 1. One end of the rotating shaft B321 is provided with a swinging rod C322, and the swinging rod C322 is arranged outside the frame 11 on the front side of the belt conveying mechanism 1. The other end of the rotating shaft B321 is provided with a swinging rod D323, and the swinging rod D323 is arranged outside the frame 11 on the rear side of the belt conveying mechanism 1.

[0038] The swinging rod A and the swinging rod B rotate with the rotation of the rotating shaft A, and the swinging rod C and the swinging rod D rotate with the rotation of the rotating shaft B.

[0039] See Figure 5 As shown in Figure 5 , the worm and worm gear transmission assembly 41 includes a worm gear 411. The worm gear 411 is arranged on the rotating shaft A311 and on the outer side of the swing rod A312. Two bases C412 are symmetrically arranged on the frame 11. A worm 413 is arranged on the base C412. The worm 413 meshes with the worm gear 411. One end of the worm 413 is provided with a motor 414. The motor 414 is arranged on the outer side of one of the bases C412 and fixedly connected to the frame 11.

[0040] Start the motor. The output shaft of the motor rotates, driving the worm to rotate. The worm meshes with the worm gear, so the worm gear rotates. And because the worm gear is arranged on the rotating shaft A, the rotating shaft A rotates, further driving the swing rod A and the swing rod B to rotate synchronously around the axis of the rotating shaft A. Among them, the worm and worm gear transmission assembly is adopted. The worm has a self-locking function, which can prevent the hopper from swinging left and right when feeding the hopper.

[0041] See Figure 5 As shown in Figure 5 , the belt transmission assembly 42 includes a pulley A421. The pulley A421 is fixedly connected to the worm gear 411. The pulley A421 is arranged on the rotating shaft A311 and on the outer side of the worm gear 411. A pulley B422 is arranged on the rotating shaft B321. A synchronous belt 423 is arranged between the pulley B422 and the pulley A421.

[0042] Because the pulley A is fixedly arranged on the front side of the worm gear, the rotation of the worm gear drives the pulley A to rotate synchronously. Through the synchronous belt, the pulley B is driven to rotate. And because the pulley B is arranged on the rotating shaft B, the swing rod C and the swing rod D on the rotating shaft B rotate synchronously.

[0043] See Figure 6 As shown in Figure 6 , the feeding mechanism 2 includes a hopper 21. The bottom of the hopper 21 is inclined. A limiting component 22 is arranged at the discharging end of the hopper 21. When the coal enters the hopper 21, it slides obliquely towards the limiting component 22.

[0044] See Figure 7 As shown in Figure 7 , the hopper 21 includes a side plate A211, a side plate B212, and a side plate C213 arranged between the left sides of the side plate A211 and the side plate B212. The side plate A211 and the side plate B212 have the same structure. A pedestal 2111 is arranged at the upper end of the side plate A211 and sinks downward. The bottom of the side plate A211 is inclined. A bottom plate 214 is arranged between the side plate A, the side plate B, and the side plate C. The limiting component 22 is arranged at the pedestal of the side plate A211 and the pedestal of the side plate B.

[0045] See Figure 7, the limiting component 22 includes a cover plate 221. A hanging plate 222 is arranged between the pedestals of the side plate A and the side plate B. A fixing seat 223 is arranged on the hanging plate 222. A fixing rod 224 is arranged on the left side of the cover plate 221. The fixing rod is pivotally connected to the fixing seat. A base A 225 is arranged on the right side of the cover plate 221. A cross bar 226 is arranged between the right ends of the side plate A and the side plate B. A base B 227 is arranged on the cross bar 226. A limiting rod 228 is pivotally arranged on the base A 225. Limiting holes 2281 are arranged in an array on the limiting rod 228. The limiting holes 2281 correspond to the base B 227.

[0046] When coal and pulverized coal are simultaneously put into the feeding hopper, since the bottoms of both the side plate A and the side plate B are inclined, the bottom plate is also inclined. The coal and pulverized coal slide on the inclined bottom plate. When they slide to the limiting component, they are blocked by the cover plate, reducing the impact force of the coal and pulverized coal sliding down and being able to reduce the impact force of the coal and pulverized coal on the belt.

[0047] See Figure 7 , two pin A are arranged on the side plate A. One end of the swing rod A is pivotally connected to one of the pin A, and the other end is pivotally connected to one end of the rotating shaft A. One end of the swing rod C is pivotally connected to the other pin A, and the other end is pivotally connected to one end of the rotating shaft B. Two pin B are arranged on the side plate B. One end of the swing rod B is pivotally connected to one of the pin B, and the other end is pivotally connected to the other end of the rotating shaft A. One end of the swing rod D is pivotally connected to the other pin B, and the other end is pivotally connected to the other end of the rotating shaft B.

[0048] The using process of the present invention includes the following steps:

[0049] Step 1: Start the motor. The rotation of the output shaft of the motor drives the worm to rotate. The rotation of the worm drives the worm wheel to rotate. The rotation of the worm wheel drives the rotating shaft A to rotate. At the same time, the rotating shaft B is driven to rotate synchronously through the synchronous belt. The rotation of the rotating shaft A drives the swing rod A and the swing rod B to rotate. At the same time, the rotation of the rotating shaft B drives the swing rod C and the swing rod D to rotate;

[0050] Step 2: While the swing rod A and the swing rod B are rotating, the swing rod C and the swing rod D are also rotating synchronously. At this time, the feeding hopper swings accordingly. When the feeding hopper is rotated to a certain angle, that is, when the right side of the feeding hopper is close to the belt, turn off the motor;

[0051] Step 3: Pull the limiting rod to ensure that there is a certain gap between the bottom of the cover plate and the upper end surface of the bottom plate. Fix the limiting rod on the base B through the limiting hole;

[0052] Step 4: Put coal and pulverized coal into the feeding hopper. The coal and pulverized coal slowly fall on the belt, effectively preventing damage to the belt by the coal and pulverized coal.

[0053] The technical features not described in the present invention can be realized by or adopted from the prior art, and will not be elaborated here. Of course, the above description is not a limitation on the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present invention shall also fall within the protection scope of the present invention.
