Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a heavy-duty safety belt conveyor for mining. Background Art

[0002] A belt conveyor is a transportation device whose conveying belt carries and transports materials. It is widely used in industries such as cement, coking, metallurgy, chemical industry, and steel. A mining belt conveyor refers to a belt conveyor used in the mining, production, transportation, and processing of minerals such as coal. A mining belt conveyor has the characteristics of large transportation volume, complex working environment, strong carrying capacity, and long transportation distance. During its transportation operation, due to the different sizes, dimensions, and weights of mineral raw materials, the use of existing trough roller belt conveyors for transportation is very likely to cause equipment damage and safety hazards. Continuous falling of materials will cause the mineral raw materials to fall on the conveyor belt and then bounce back, creating a safety hazard. In addition, the materials adhered and accumulated on the conveyor belt are not easy to clean. During operation, the materials will fall on the return section of the conveyor belt, polluting the workplace and are not easy to collect and recycle. Utility Model Content

[0019] like Figures 1 to 5 As shown, this embodiment provides a heavy-duty safety belt conveyor for mining, including a belt conveying mechanism 1, the belt conveying mechanism 1 includes a frame 108 and a conveying belt 104 movably mounted on the frame 108 and running along the longitudinal direction of the frame 108, a support frame 105 is provided below the conveying surface of the conveying belt 104, the support frame 105 includes a plurality of small platforms 1051 arranged along the longitudinal direction of the frame 108, a protective cover 3 is provided above the conveying surface of the conveying belt 104, a cleaning mechanism and a buffer plate 112 are provided at the unloading end of the belt conveying mechanism 1, the cleaning mechanism includes a connecting frame 109 mounted on the frame 108, and a rotatable connecting frame 109 mounted on the connecting frame 109. A cleaning roller 110 is provided on the connecting frame 109, and a cleaning motor 111 for driving the cleaning roller 110 to rotate is installed on the connecting frame 109. The connecting frame 109 is arranged below the conveying belt 104, and the cleaning roller 110 abuts against the lower part of the conveying belt 104. The upper end of the buffer plate 112 is hinged on the connecting frame 109, and the lower end of the buffer plate 112 is connected to the connecting frame 109 through a rubber column 113. A feed protection cover 2 is installed at the feeding end of the belt conveying mechanism 1, and a feed port 2011 is provided on the feed protection cover 2, and a buffer inclined plate 203 is provided below the feed port 2011. The heavy-duty belt conveyor for mining in this embodiment is not easy to be damaged and has a high safety factor.

[0020] In this embodiment, the conveying mechanism includes an active roller 101 and a driven roller 102 rotatably mounted at both ends of a frame 108, the conveying belt 104 is sleeved on the active roller 101 and the driven roller 102, the frame 108 is equipped with a motor 103 for driving the active roller 101 to rotate, the support frame 105 is arranged above the frame 108 and abuts against the conveying belt 104, and the support frame 105 with multiple small platforms 1051 evenly distributes the weight of the conveying belt 104 to prevent the conveying belt 104 from being damaged due to excessive weight of the material. Preferably, a plurality of lower rollers 106 are installed at the lower part of the frame 108, the lower rollers 106 abut against the lower part of the conveying belt 104, the lower rollers 106 and the conveying belt 104 are rollingly matched, and the plurality of lower rollers 106 support the conveying belt 104 to prevent the conveying belt 104 from falling and ensure that the force on the conveying belt 104 is uniform.

[0021] In this embodiment, there are multiple protective covers 3, and the multiple protective covers 3 are arranged longitudinally along the frame 108 and abutted together. Each protective cover 3 is provided with a handle 301. The frame 108 is provided with two rows of symmetrically arranged support frames 107. The protective covers 3 are placed on the support frames 107 at corresponding positions. Multiple protective covers 3 can cover the conveyor belt 104 and play a good dust-proof role. A single protective cover 3 can be opened separately to check the material condition.

[0022] The feed protection cover 2 of this embodiment includes a limit plate 201 and three baffles 202 arranged in a concave shape. The limit plate 201 is provided with a feed port 2011. The buffer inclined plate 203 is connected to two parallel baffles 202 and its high end points to the feed port 2011. The limit plate 201 can be installed on the upper-level conveying unit. When the material is thrown onto the conveying belt 104 from the feed port 2011, it will first contact the buffer inclined plate 203. The buffer inclined plate 203 will guide the movement direction of the material and slow down the speed of the material, so that the material will not directly hit the conveying belt 104, effectively protecting the conveying belt 104. The baffle 202 can prevent the material from rebounding and splashing out of the conveying belt 104.

[0023] The support frame 105 of the mining heavy-duty safety belt conveyor of this embodiment has multiple small platforms 1051 arranged along the longitudinal direction of the frame 108. The multiple small platforms 1051 evenly support the conveyor belt 104 and the materials thereon, which can prevent the conveyor belt 104 from being damaged. The feed protection cover 2 can prevent the materials from falling on the conveyor belt 104 and bouncing back to cause safety hazards. The protection cover 3 plays a role in dust prevention and preventing the materials from detaching from the conveyor belt 104. The cleaning roller 110 of this embodiment will sweep the materials on the conveyor belt 104, and the swept materials will fall on the buffer plate 112. When the conveyor belt is unloading, the materials will fall on the buffer plate 112 and then fall into the unloading area. The buffer plate 112 plays a buffering role. At the same time, the buffer plate 112 vibrates, so that the swept fine materials can fall along the buffer plate 112 to the unloading area, avoiding the materials from being scattered everywhere and realizing the recovery of the fine materials.
