Description

Technical Field

[0001] This invention belongs to the field of material conveying technology, and in particular relates to a conveying equipment for mining machinery. Background Technology

[0002] Mining machinery conveying equipment is a type of equipment specifically designed for industries such as mining, ore extraction and processing. It is mainly used for conveying, handling and transporting materials. These devices are widely used in fields such as mining, stone processing and coal transportation to reduce the amount of manual handling work and improve transportation efficiency and production capacity.

[0003] Currently, traditional mining machinery conveying equipment often relies on manual handheld water guns or offline tumbling and scraping to clean attached impurities after material transport. However, high-pressure water washing increases the load on wastewater tanks and becomes ineffective when the equipment freezes in winter. Offline tumbling and scraping, on the other hand, wears down the anti-slip grooves on the conveyor. Once these grooves are smoothed out by hard objects, the coefficient of friction of the conveyor drops sharply, making it prone to material slippage and accumulation accidents. Therefore, we propose a new type of mining machinery conveying equipment. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a mining machinery conveying device.

[0005] To achieve the above objectives, the present invention proposes a mining machinery conveying device, including protective plates, two protective plates, and multiple transmission wheels rotatably arranged between the two protective plates.

A second limiting slider is provided inside the second limiting groove, and both ends of the drive shaft pass through the second limiting slider inside the second limiting groove.

[0010] Preferably, the auxiliary vibration assembly includes a connecting belt sleeved on both ends of the outer wall of the conveyor belt and a fixing block disposed on the upper end face of the second limiting slider. Multiple protrusions are evenly spaced on the side wall of the connecting belt away from the conveyor belt, and a chamfer is provided at the corner of the protrusion away from the connecting belt.

[0011] Preferably, the upper end face of the fixing block is provided with a groove, a helical spring is provided at the bottom of the inner side of the groove, a top block is inserted into the inner side of the groove, and an inclined angle is provided at one corner of the upper end face of the top block, the inclined angle is in the opposite direction to the direction of travel of the protrusion on the connecting belt.

The tension of the conveyor belt can be compensated by finely adjusting the driven roller in the vertical direction through the setting of the tensioning component. Attached Figure Description

[0024] like Figures 1-6As shown, an embodiment of the present invention proposes a mining machinery conveying device, including a protective plate 1. Two protective plates 1 are provided, and multiple transmission wheels 21 are rotatably arranged between the two protective plates 1. The multiple transmission wheels 21 are arranged in a straight line, and a conveyor belt 2 is sleeved on the multiple transmission wheels 21. Multiple baffles 5 are arranged at equal intervals on the conveyor belt 2. A bending and impurity removal component 6 is provided between the two protective plates 1. The bending and impurity removal component 6 includes a bending and cleaning component 61 and an auxiliary vibration component 62. A tensioning component 7 is connected above the bending and cleaning component 61.

[0025] It should be noted that a drive motor is installed on a protective plate 1, and the output end of the drive motor is connected to a transmission wheel 21 to drive the conveyor belt 2 to rotate. Since the drive motor driving the conveyor belt 2 is not the technical solution improved in this application, the specific principle can be referred to the prior art. The conveyor belt 2 is made of rubber.

[0026] The bending and cleaning assembly 61 includes a driven roller 611 rotatably disposed between two protective plates 1. The driven roller 611 is located below a plurality of transmission wheels 21. The conveyor belt 2 is sleeved on the driven roller 611. A first limiting groove 612 is provided on the protective plate 1. A first limiting slider 613 is slidably disposed inside the first limiting groove 612. The tensioning assembly 7 is connected to the first limiting slider 613.

[0027] The driven roller 611 supports the conveyor belt 2, so that the trajectory conveyed by the conveyor belt 2 is triangular.

[0028] Two first transmission gears 614 are rotatably mounted on the first limiting slider 613. The two first transmission gears 614 are connected by a first toothed belt 615. The protective plate 1 has an opening. The two ends of the driven roller 611 are respectively connected to the first limiting sliders 613 on the two protective plates 1 through connecting shafts. The two connecting shafts on the driven roller 611 pass through the openings on the two protective plates 1. The connecting shafts at both ends of the driven roller 611 are respectively connected to one of the first transmission gears 614 on the first limiting sliders 613 on the two protective plates 1.

[0029] The first limiting groove 612 on the protective plate 1 corresponds to the position of the through-hole. A drive shaft is provided between the two protective plates 1. A first cleaning brush 616 is provided on the drive shaft. The two ends of the drive shaft pass through the through-holes on the two protective plates 1 respectively and are rotatably connected to the first limiting sliders 613 inside the two first limiting grooves 612. A first transmission gear 614 on the first limiting slider 613 is connected to the drive shaft connected to the first limiting slider 613.

[0030] The two protective plates 1 are provided with a second limiting groove 617 on one side wall, and the second limiting groove 617 corresponds to the opening position of the protective plate 1. A second limiting slider 618 is provided inside the second limiting groove 617, and the two ends of the drive shaft pass through the second limiting slider 618 inside the second limiting groove 617.

[0031] The first limiting groove 612 and the second limiting groove 617 both have an I-shaped cross section. The first limiting slider 613 and the second limiting slider 618 are adapted to the shape and size of the first limiting groove 612 and the second limiting groove 617, respectively. The limiting grooves with I-shaped cross sections play a role in limiting and guiding the movement of the limiting sliders.

[0032] In this embodiment, the mined ore is first placed onto the conveyor belt 2, which then transports the material to the target location. During the material transport process, the driven roller 611 rotates along with the conveyor belt 2. The rotation of the driven roller 611 drives the first transmission gear 614 connected to it to rotate, which in turn drives another first transmission gear 614 to rotate via the first toothed belt 615. The rotation of the first transmission gear 614 drives the drive shaft connected to it to rotate, which in turn drives the first cleaning brush 616 to rotate. When the conveyor belt 2, after transporting the material, rotates to the driven roller 611, the lower end face of the conveyor belt 2 located below the driven roller 611 is stretched, thereby enlarging the gaps and anti-slip patterns on the conveyor belt 2. The rotating first cleaning brush 616 cleans the impurities inside the enlarged gaps and anti-slip patterns on the conveyor belt 2.

[0033] By setting the bending cleaning component 61, the conveyor belt 2 is made to transport materials in a triangular trajectory. This not only cleans the impurities attached to the conveyor belt 2 and keeps it clean, but also prevents the accumulation of impurities with strong adhesion, thereby reducing the operating load of the device caused by the increase in conveying weight. In addition, it can also clean impurities embedded in the anti-slip texture, so that the anti-slip texture on the conveyor belt 2 can be kept intact, thereby making the conveying of materials on the conveyor belt 2 stable.

[0034] The auxiliary vibration assembly 62 includes a connecting belt 621 sleeved on the front and rear ends of the outer wall of the conveyor belt 2 and a fixing block 623 set on the upper end of the second limiting slider 618. Multiple protrusions 622 are evenly spaced on the side wall of the connecting belt 621 away from the conveyor belt 2, and a chamfer is provided at the corner of the protrusion 622 away from the connecting belt 621.

[0035] It should be noted that the connecting belt 621 is a metal belt, and metal belts can vibrate when subjected to force.

[0036] The upper end face of the fixing block 623 is provided with a groove 624, the bottom of the inner side of the groove 624 is provided with a spiral spring 625, the inner side of the groove 624 is provided with a top block 626, and the upper end face of the top block 626 is provided with an inclined angle at one corner, the inclined angle is in the opposite direction to the direction of travel of the protrusion 622 on the connecting belt 621.

[0037] It should be noted that the chamfer on the protrusion 622 and the tilt angle on the top block 626 allow the top block 626 to slide smoothly to the top of the protrusion 622, avoiding motion conflict between the protrusion 622 and the top block 626.

[0038] In this embodiment, during the rotation of the conveyor belt 2, the connecting belt 621 and the protrusion 622 disposed on the conveyor belt 2 will rotate along the conveying trajectory of the conveyor belt 2. When the protrusion 622 on the connecting belt 621 rotates to the top block 626 on the second limiting slider 618, the top block 626 will slide along the chamfer on the protrusion 622 towards the top of the protrusion 622. At this time, the top block 626 retracts into the groove 624 on the fixing block 623. During the retraction process, the top block 626 will squeeze the spiral spring 625 inside the groove 624 until the top block 626 slides along the chamfer of the protrusion 622 to the top of the protrusion 622. When the top block 626 and the protrusion 622 are misaligned, the spiral spring 625 pushes the top block 626 to strike the connecting belt 621 through its elastic characteristics. At this time, the connecting belt 621 is subjected to force, causing the area of ​​the conveyor belt 2 located below the driven roller 611 to vibrate. The vibration of the conveyor belt 2 will loosen the relatively firmly attached impurities.

[0039] By setting the auxiliary vibration component 62, micro-vibration is generated in the area of ​​the conveyor belt 2 located below the driven roller 611. This can loosen the firmly attached impurities in advance, thereby improving the cleaning effect of the first cleaning brush 616 on the impurities on the conveyor belt 2.

[0040] The tensioning assembly 7 includes a connecting seat 71 disposed on the protective plate 1 and a connecting horizontal plate 73 disposed on the first limit slider 613. The connecting seat 71 is provided with a telescopic device 72, the output end of which is connected to the connecting horizontal plate 73.

[0041] In this embodiment, if the tension of the conveyor belt 2 becomes loose after long-term use, the telescopic device 72 is activated. The telescopic device 72 drives the first limiting slider 613 to move through the connecting horizontal plate 73. The first limiting slider 613 drives the driven roller 611 to move down along the first limiting groove 612. The downward movement of the driven roller 611 will tighten the loose conveyor belt 2.

[0042] The tension of the conveyor belt 2 can be compensated by finely adjusting the driven roller 611 in the vertical direction through the setting of the tensioning component 7; the tensioning process of the conveyor belt 2 does not require manual adjustment with a wrench and can be completed with one click, reducing the time from the original 15 minutes to 1 minute, the offset of the conveyor belt 2 is always ≤2mm, and the triangular conveying trajectory remains constant.

[0043] A support leg 3 and a telescopic leg 4 are rotatably connected to one side wall of the protective plate 1. The support leg 3 and the telescopic leg 4 together support the protective plate 1. The two ends of the transmission wheel 21 are provided with second transmission gears 22. The two sides of the multiple transmission wheels 21 are provided with second toothed belts 23. The two second toothed belts 23 are respectively connected to the second transmission gears 22 at both ends of the multiple transmission wheels 21.

[0044] It should be noted that the telescopic leg 4 can be a pneumatic cylinder, hydraulic cylinder, etc.

[0045] In this embodiment, when it is necessary to transport the material to a height higher than or lower than the horizontal plane of the conveyor belt 2, the telescopic leg 4 is activated. After the telescopic leg 4 is activated, it raises or lowers one end of the conveyor belt 2 to a suitable height through telescopic movement, and then the material is placed on the conveyor belt 2 for transport.

[0046] By using support legs 3 and telescopic legs 4, the conveyor belt 2 can transport materials to different heights. When the conveyor belt 2 is used in conjunction with the baffle 5, it reduces the amount of material on the conveyor belt 2 from sliding down the inclined surface towards the material delivery point when the conveyor belt 2 is in an inclined state.

[0047] Two protective plates 1 are provided with a second cleaning brush 8 on one side of the wall. The two second cleaning brushes 8 correspond to the positions of the two connecting strips 621 respectively, and the brushes of the two second cleaning brushes 8 press against the two connecting strips 621 respectively.

[0048] In this embodiment, when the protrusion 622 on the connecting belt 621 passes the second cleaning brush 8, the second cleaning brush 8 cleans the impurities attached to the connecting belt 621 and the protrusion 622 on the connecting belt 621, so as to avoid the accumulation of impurities on the connecting belt 621 and the protrusion 622 from affecting the use of the auxiliary vibration component 62.

[0049] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0050] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
