Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and in particular relates to a stone loading device for mines. Background Art

[0002] The stone loading device for mining is a mechanical equipment specially used for loading mined stone in a mining environment. Belt conveyor is a common type of stone loading equipment.

[0003] Belt conveyors can achieve tilted conveying at a certain angle to accommodate loading requirements at varying heights. The tilt angle can be adjusted based on actual conditions to improve loading flexibility. The conveyor belt operates continuously, enabling continuous material transport and improving loading efficiency. Conveyor belts are typically equipped with several barrier strips that shield the stone from the loop, reducing the risk of stone rolling off during upward tilt and improving loading efficiency. However, some barrier strips are prone to wear and tear, and are typically installed in a removable manner. However, when the conveyor belt reaches a bend, the curve can create gaps between the barrier strip and the belt, allowing material to accumulate or become stuck near these gaps. This results in greater friction in these areas, exacerbating localized wear. Hard ore particles become lodged in these gaps, and as the conveyor belt moves, they continuously scrape the belt like sandpaper, roughening its surface and reducing its service life.

[0018] See also Figure 1-Figure 4 The utility model provides the following technical solutions: it includes a transfer conveyor 1, the transfer conveyor 1 includes a support frame 11, two driving rollers 12 and a conveyor belt 13, and a plurality of feeding baffles 2 are installed on the conveyor belt 13. The bottom ends of the plurality of feeding baffles 2 are provided with two accommodating grooves 21, and the inner wall of the accommodating groove 21 is slidably connected with a baffle plate 22. The baffle plate 22 contacts one end of the conveyor belt 13, and a plurality of sliding blocks 23 are fixedly connected to one side of the baffle plate 22. A plurality of inner sliding grooves 24 are provided in the feeding baffle 2, and the sliding blocks 23 are slidably connected to the inner walls of the corresponding inner sliding grooves 24. The inner walls of the inner sliding grooves 24 are fixedly connected with compression springs 241, and one end of the compression spring 241 is fixedly connected to one side of the corresponding sliding block 23.

[0019] In this embodiment, the support frame 11 supports each component of the device, and the two driving rollers 12 drive the conveyor belt 13 so that the conveyor belt 13 can rotate. The conveyor belt 13 transports the stone from the bottom to the top. One end of the device is tilted. When the stone reaches the tilted end of the device, the ore then falls down into the transport vehicle to realize the loading of the stone. The device can operate continuously, which improves the loading efficiency. The feeding baffle 2 is installed on the conveyor belt 13, and the feeding baffle 2 is placed horizontally on the conveyor belt 13 so that the conveyor When the belt 13 is used to transport and load stones, several feeding baffles 2 can block the stones on the inclined conveyor belt 13, reduce the situation that stones on the conveyor belt 13 fall off, and further improve the loading efficiency. The feeding baffle 2 and the conveyor belt 13 are detachably connected. The feeding baffle 2 accommodates the baffle plate 22 through the accommodating groove 21. The baffle plate 22 slides telescopically in the inner wall of the accommodating groove 21. The baffle plate 22 can extend out of the accommodating groove 21. The inner slide groove 24 makes way for the sliding block 23. The inner slide groove 24 slides The moving block 23 limits the baffle plate 22 to prevent the baffle plate 22 from escaping from the accommodating groove 21. The compression spring 241 pushes the sliding block 23 so that the sliding block 23 can push the baffle plate 22 out, thereby making the baffle plate 22 stably contact with the conveyor belt 13. The baffle plate 22 blocks the gap between the feeding baffle plate 2 and the conveyor belt 13. When the conveyor belt 13 moves to the position of the driving roller 12, the conveyor belt 13 is affected by the driving roller 12 and becomes bent, and the feeding baffle plate 2 is in the feeding position. When the conveyor belt 13 is connected to the driving roller 12, a gap will be generated between the feed baffle 2 and the conveyor belt 13. At this time, the compression spring 241 pushes the sliding block 23, and the sliding block 23 drives the baffle plate 22 to continue to extend toward the conveyor belt 13, so that the sliding block 23 can prevent the fine particles in the mineral material from entering the enlarged gap between the feed baffle 2 and the conveyor belt 13 and gathering or getting stuck, thereby reducing the local friction force on the conveyor belt 13, thereby reducing local wear, improving the service life of the device, and ensuring stability in use.

[0020] The inner wall of the inner slide groove 24 is fixedly connected with a guide slide rod 242, which passes through one end of the sliding block 23, and the sliding block 23 is slidably connected to the side wall of the corresponding guide slide rod 242; the feed baffle 2 supports the guide slide rod 242, and the guide slide rod 242 guides the sliding block 23 for sliding. When the compression spring 241 pushes the sliding block 23 to slide inside the inner slide groove 24, the sliding block 23 slides along the guide slide rod 242 to prevent the sliding block 23 from causing the feed baffle 2 to slide, deflect or tilt.

[0021] When the cam 31 is in the working state, the cam 31 is in the working state, and the cam 31 is in the working state, so that the cam 31 is in the working state and the cam 31 is in the working state, the cam 31 is in the working state, and the cam 31 is in the working state, so that the cam 31 is in the working state and the cam 31 is in the working state.

[0022] Several protrusions 132 are fixedly connected to the outside of the conveyor belt 13, and two docking slots 25 are provided at the bottom end of the feed baffle 2. The protrusions 132 are engaged and connected to the inner walls of the corresponding docking slots 25, and the connecting bolts 3 pass through one end of the corresponding protrusions 132; the conveyor belt 13 is engaged with the docking slots 25 through the protrusions 132, so that the feed baffle 2 is limited by the protrusions 132 on the conveyor belt 13, preventing the feed baffle 2 and the conveyor belt 13 from sliding sideways, and the connecting bolts 3 pass through the protrusions 132 to be connected to the connecting disk 32, so that the connecting bolts 3 can increase the limiting strength and stability of the protrusions 132.

[0023] Two annular grooves 121 are provided on the driving roller 12, and the driving roller 12 makes way for the connecting disk 32 through the annular grooves 121; when the feeding baffle 2 and the connecting bolt 3 follow the conveyor belt 13 to reach the position of the driving roller 12, the connecting disk 32 is engaged into the annular groove 121, so that the driving roller 12 will not contact the connecting disk 32, thereby preventing the connecting disk 32 from being affected by the interference of the driving roller 12, thereby improving the stability of the connecting disk 32 during use.

[0024] Two pressure sensors 33 are installed on the end of the connecting disk 32 close to the feeding baffle 2. The pressure sensor 33 contacts the inner wall of the give way slot 131 through the sphere 331. The end of the connecting disk 32 away from the conveyor belt 13 is hinged with an arc plate 34; the pressure sensor 33 is in the clamping space between the connecting disk 32 and the conveyor belt 13, and the sphere 331 reduces the sliding friction between the pressure sensor 33 and the give way slot 131. When the connection between the feeding baffle 2 and the conveyor belt 13 is loose, the tightness between the connecting disk 32 and the conveyor belt 13 is reduced, so that the pressure sensor 33 can detect the looseness between the connecting disk 32 and the conveyor belt 13, and promptly transmit data to the staff, and promptly repair and tighten it to avoid damage to the device or loss of parts.

[0025] The working principle and usage process of the utility model are as follows: when the vehicle is loaded with stone, the two driving rollers 12 rotate, and the driving rollers 12 drive the conveyor belt 13 to transport the stone. The conveyor belt 13 transports the stone from the bottom to the top. When the stone reaches the raised end of the device, the ore then falls down into the transport vehicle to realize the loading of the stone. The device can operate continuously, which improves the loading efficiency. When the conveyor belt 13 drives the feeding baffle 2 to reach the position of the driving roller 12, the conveyor belt 13 becomes bent by the influence of the driving roller 12, and a gap will be generated between the feeding baffle 2 and the conveyor belt 13. At this time, the compression spring 241 pushes the sliding block 23, and the sliding block 23 drives the baffle plate 22 to continue to extend toward the conveyor belt 13, so that the sliding block 23 can prevent the fine particles in the ore from entering the enlarged gap between the feeding baffle 2 and the conveyor belt 13 and gathering or getting stuck.
