Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of coal mine operations, and more specifically, to a uniform distribution device for material buffering in mine transfer machines. Background Technology

[0002] In coal mining operations, transfer conveyors, as key equipment in the coal transportation system, bear the important task of transferring coal mined by the coal mining machine from the face scraper conveyor to subsequent transportation equipment. With the continuous expansion of coal mining scale and the continuous improvement of mining efficiency, the material transportation problems faced by transfer conveyors during operation have become increasingly prominent, especially in terms of material falling impact and discharge control, which have adversely affected production efficiency, equipment life and safe production.

[0003] In actual production, after the coal is cut by the coal mining machine, it is conveyed at high speed to the transfer conveyor via a scraper conveyor. Due to the significant height the coal falls from and its considerable speed and mass, a strong impact is generated when it comes into contact with the receiving components of the transfer conveyor. This impact not only causes severe wear on the chutes, scrapers, and other parts of the transfer conveyor, shortening equipment lifespan and increasing maintenance costs and downtime, but also results in unstable material flow when the transfer conveyor receives coal, as coal production varies in different mining areas and the cutting speed of the coal mining machine is not constant. If the discharge rate cannot be effectively controlled, it will place significant operational pressure on subsequent transportation equipment. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a uniform distribution device for material buffering of a mining transfer machine, which solves the technical problem in the prior art that, due to the large falling height of coal and its certain speed and mass, a strong impact will be generated when it comes into contact with the receiving parts of the transfer machine. This impact will not only cause serious wear on the chute, scraper and other parts of the transfer machine, shorten the service life of the equipment, but also increase the equipment maintenance cost and downtime.

[0005] According to one aspect, at least one embodiment of this disclosure provides a uniform distribution device for material buffering in a mining transfer machine, comprising:

[0032] like Figures 1-4 As shown, it illustrates a uniform distribution device for material buffering in a mining transfer machine according to an embodiment of the present disclosure, comprising:

[0033] The outer frame 1 and the drive motor 2 are disposed on the side surface of the outer frame 1;

[0034] Buffer receiving assembly 4, which is disposed inside the outer frame 1;

[0035] The inner baffle 3 and the material feeding control component 5 are provided. The inner baffle 3 is fixed inside the outer frame 1, and the material feeding control component 5 is disposed inside the outer frame 1.

[0036] The buffer receiving assembly 4 includes a pair of rotating frames 4-1, which are rotatably connected to the inner sides of the outer frame 1. The drive motor 2 is connected to one of the rotating frames 4-1. A plurality of buffer springs 4-2 are arranged around the surface of the rotating frame 4-1. A pusher roller 4-3 is arranged outside the rotating frame 4-1. The rotating frame 4-1 is located at both ends inside the pusher roller 4-3. The inner surface of the pusher roller 4-3 is connected to the buffer springs 4-2. A vibration motor 4-4 is fixedly connected inside the pusher roller 4-3.

[0037] In some examples, to effectively buffer and push materials, prevent material damage during receiving, and improve receiving and feeding efficiency, a buffer receiving assembly 4 is designed. The buffer receiving assembly 4 proposed in this embodiment mainly consists of a pair of rotating frames 4-1, which are rotatably connected to both sides inside the outer frame 1. A drive motor 2 is connected to one of the rotating frames 4-1, providing power for the rotation of the rotating frame 4-1, allowing it to rotate around its axis. Several buffer springs 4-2 are arranged around the surface of the rotating frame 4-1. These buffer springs 4-2 are key components for achieving the buffering function. When material contacts the pusher roller 4-3, the buffer springs 4-2 absorb the impact force of the material, playing a buffering and shock-absorbing role, reducing damage caused by impact, and protecting the material. To ensure the integrity of the material, a pusher roller 4-3 is installed on the outside of the rotating frame 4-1. The rotating frame 4-1 is located at both ends inside the pusher roller 4-3, and the inner surface of the pusher roller 4-3 is connected to the buffer spring 4-2. This structural design allows the pusher roller 4-3 to rotate with the rotating frame 4-1. At the same time, the elastic force of the buffer spring 4-2 allows the pusher roller 4-3 to better contact the material and push the material. In addition, a vibration motor 4-4 is fixedly connected inside the pusher roller 4-3. When the vibration motor 4-4 is working, it will cause the pusher roller 4-3 to vibrate. This vibration can make the material more evenly distributed on the pusher roller 4-3, avoid material accumulation, and help the material conveying, thus improving the feeding efficiency. Through the combined action of the vibration motor 4-4 and the buffer spring 4-2, both the buffer protection of the material during the receiving process and the material conveying effect are ensured.

[0038] like Figures 1-4 As shown in the figure, the material feeding control component 5 in this embodiment includes a pair of telescopic cylinders 5-1. The telescopic cylinders 5-1 are fixed at both ends of the surface of the inner baffle 3. The output end of the telescopic cylinders 5-1 is connected to a baffle plate 5-2. The baffle plate 5-2 is slidably connected to the inner sides of the outer frame 1. One end of the bottom of the outer frame 1 is an open structure. A guide frame 5-3 is provided at the bottom of the outer frame 1. A pair of movable frames 5-4 are slidably connected to the guide frame 5-3. One end of the movable frame 5-4 is connected to a blocking plate 5-5. Several discharge ports 5-6 are opened on the surface of the blocking plate 5-5. A second cylinder 5-7 is fixedly connected to the bottom of the outer frame 1. The output end of the second cylinder 5-7 is connected to the movable frame 5-4.

[0039] In some examples, to achieve precise control of the material feeding process and ensure that the feeding quantity and speed meet production requirements, a feeding control component 5 is designed. The feeding control component 5 proposed in this embodiment includes a pair of telescopic cylinders 5-1. These telescopic cylinders 5-1 are fixed at both ends of the inner baffle 3 surface. The output end of the telescopic cylinders 5-1 is connected to a baffle plate 5-2, and the baffle plate 5-2 can be slidably connected to both sides of the outer frame 1. When the telescopic cylinders 5-1 are working, the telescopic movement of their output ends will cause the baffle plate 5-2 to slide on both sides of the outer frame 1. By controlling the position of the baffle plate 5-2, the opening and closing degree of the material channel inside the outer frame 1 can be adjusted, thereby providing preliminary control over the material feeding. When the baffle plate 5-2 is closed, it can prevent the material from falling; when the baffle plate 5-2 is opened to a certain extent, the material can fall at a corresponding speed and quantity according to the opening size. One end of the bottom of the outer frame 1 has an open structure, facilitating... Material flows out from the outer frame 1. A guide frame 5-3 is set at the bottom of the outer frame 1. A pair of movable frames 5-4 are slidably connected to the guide frame 5-3. One end of the movable frame 5-4 is connected to a baffle plate 5-5. Several discharge ports 5-6 are opened on the surface of the baffle plate 5-5. The size and number of discharge ports 5-6 determine the final discharge amount and discharge speed of the material. A second cylinder 5-7 is also fixedly connected to the bottom of the outer frame 1. The output end of the second cylinder 5-7 is connected to the movable frame 5-4. When the second cylinder 5-7 works, it will drive the movable frame 5-4 to slide on the guide frame 5-3, thereby moving the baffle plate 5-5. By controlling the second cylinder 5-7, the position of the baffle plate 5-5 can be adjusted, changing the relative position and overlapping area of ​​the discharge port 5-6 and the bottom opening of the outer frame 1. When the discharge port 5-6 and the bottom opening of the outer frame 1 are completely overlapped, the discharge amount is the maximum. When they partially overlap or do not overlap, the discharge amount can be precisely controlled according to the degree of overlap.

[0040] For example, such as Figure 1 As shown, a pair of height-increasing frames 6 are provided at the bottom of the outer frame 1.

[0041] In some examples, the height of the outer frame 1 is increased by setting up an extension frame 6 to facilitate docking with the transfer machine.

[0042] For example, such as Figure 3 As shown, the inner bottom surface of the outer frame 1 is an arc-shaped transition structure surface, and the inner part of the outer frame 1 is an inclined structure surface.

[0043] In some examples, the combination of curved and inclined structural surfaces prevents material from entering the interior and allows it to slide out.

[0044] For example, such as Figure 3 As shown, the lower end face of the barrier plate 5-2 is slidably attached to the surface of the barrier plate 5-5.

[0045] In some examples, sliding bonding reduces gaps and prevents material from entering and causing wear.

[0046] When operation is required, drive motor 2 starts, providing power to the rotating frame 4-1 connected to it, causing it to rotate around its axis. When the coal mined by the coal mining machine is conveyed to the device at high speed by the scraper conveyor, the coal comes into contact with the pusher roller 4-3. At this time, the buffer spring 4-2 on the surface of the rotating frame 4-1 plays its role, absorbing the impact force of the coal and reducing damage caused by the impact. Since the rotating frame 4-1 is located at both ends inside the pusher roller 4-3 and the inner surface of the pusher roller 4-3 is connected to the buffer spring 4-2, the pusher roller 4-3 will rotate with the rotating frame 4-1, thereby pushing the coal to move within the device. At the same time, the vibration motor 4-4 inside the pusher roller 4-3 works, causing the pusher roller 4-3 to vibrate, making the coal more evenly distributed on the pusher roller 4-3, avoiding accumulation, and improving feeding efficiency.

[0047] Initial adjustment of material feeding: Telescopic cylinder 5-1 is fixed at both ends of the inner baffle 3 surface, and its output end is connected to the baffle plate 5-2, which is slidably connected to both sides of the outer frame 1. According to actual production needs, the telescopic cylinder 5-1 is controlled to extend and retract, causing the baffle plate 5-2 to slide on both sides of the outer frame 1. When it is necessary to reduce the feeding amount or stop feeding, the baffle plate 5-2 can be moved towards the center to reduce the opening and closing degree of the material channel in the outer frame 1, or even completely close the channel to prevent the material from falling; when it is necessary to increase the feeding amount, the baffle plate 5-2 is moved to both sides to increase the channel opening, so that the material can fall at the corresponding speed and amount.

[0048] Precise control of material feeding: The bottom of the outer frame 1 is open at one end. A pair of movable frames 5-4 are slidably connected to a guide frame 5-3 at the bottom. One end of each movable frame 5-4 is connected to a baffle plate 5-5. The surface of the baffle plate 5-5 has several discharge ports 5-6. The output end of the second cylinder 5-7 at the bottom of the outer frame 1 is connected to the movable frame 5-4. By controlling the second cylinder 5-7, the movable frame 5-4 slides on the guide frame 5-3, thereby moving the baffle plate 5-5. By adjusting the position of the baffle plate 5-5, the relative position and overlapping area between the discharge ports 5-6 and the bottom opening of the outer frame 1 are changed. For example, when the discharge ports 5-6 completely overlap with the bottom opening of the outer frame 1, the material feeding reaches its maximum; when partially overlapping, the material feeding can be precisely controlled according to the degree of overlap.
