Description

Technical Field

[0001] The utility model patent belongs to the technical field of material distribution equipment, and specifically relates to a material distribution bin for loading materials into a truck using a mining conveyor. Background Art

[0002] At present, two methods are generally adopted to ensure the continuous operation of mining and stripping production. These two methods are as follows: one is to use the rear end belt of the conveyor as a shifting belt, and cooperate with the rock discharger to discharge materials at a fixed point. The discharged materials do not need to be transported secondary, and new material stacking space is created by the movement of the soil discharger's carriage and the shifting belt; the second is that the rear end of the conveyor is not equipped with a shifting belt and a rock discharger, or when the movement of the soil discharger's carriage and the shifting belt cannot create an economically feasible material stacking space, it is necessary to use shoveling equipment to shovel and transport the materials to a specific area for stacking after the conveyor is used.

[0003] Normally, in the mining process, due to insufficient material stacking space, the second method is often used to free up material stacking space through secondary shoveling and transportation. However, this secondary shoveling and transportation method consumes a lot of manpower and material resources, and increases production costs. Therefore, the inventors have found that if the materials can be divided and transported when the mining conveyor conveys them, it will save a lot of manpower and material resources. However, in medium and large open-pit mines, due to the large amount of waste rock or ore required for transport, it is often necessary to use conveyors with large transportation capacity and fast running speed. Therefore, the impact force of the materials transmitted from the conveyor port will be very large and the force surface of the material impact point is wide, so it is impossible to load and transport directly.

[0004] Therefore, this paper proposes a sub-bin for loading materials into a mine conveyor. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a material loading and unloading sub-bin for a mining conveyor, which buffers and unloads the material transported by the conveyor and diverts it, so as to achieve the purpose of directly loading and reversing the material transported by the conveyor.

[0006] In order to achieve the above-mentioned technical effect, the utility model is realized through the following technical scheme: a distribution bin for loading materials onto trucks using a mining conveyor, comprising a conveyor, a bin, and a distribution structure. The discharge end of the conveyor is installed on the front upper part of the bin, and the bottom of the bin is equipped with a distribution structure. The bin also includes a bin body, a pedestrian inspection partition, a buffer cone, and an air cannon. Pedestrian inspection partitions are arranged on the front and rear sides of the bin body, and a buffer cone is installed on the front and rear center axis of the bottom of the bin body. The front and rear ends of the buffer cone are connected to the pedestrian inspection partition, and an air cannon that can prevent material blockage is installed at the bottom of the inner side of the buffer cone opposite to the entrance of the distribution structure; the distribution structure also includes a material chute and a discharge valve. A plurality of material chutes are installed at the bottom of the bin body on the left and right sides of the buffer cone, and the discharge valve is installed on the outlet of the material chute.

[0007] Preferably, a buffer pedestal or a wear-resistant strip A is provided on the silo wall of the silo that is susceptible to impact by materials.

[0008] Preferably, the cone height of the buffer cone is set to 2 / 3 of the depth of the warehouse body, and a plurality of wear-resistant strips B are welded on the cone surface of the buffer cone.

[0009] Preferably, the material chute extends to the left and right sides of the warehouse body at an overall inclination angle of 45°, the upper inlet of the material chute is larger than the lower outlet, and the side plates and bottom plates of the material chute are installed with wear-resistant liners.

[0010] Preferably, an air cannon is installed at the upper middle position of the bottom plate of the material chute.

[0011] Preferably, the discharge valve also includes a central shaft, a hanging door, gears, and a hydraulic cylinder. The central shaft is divided into two groups on the left and right, which are rotatably installed on the front and rear side walls of the material chute respectively. The hanging door is divided into two groups on the left and right, which are rotatably installed on the corresponding central shafts respectively. Meshing gears are arranged on the left and right groups of central shafts. The hydraulic cylinder is installed on the side wall of the material chute on the side of the warehouse body and the driving end is connected to the hanging door on the side of the warehouse body.

[0012] The beneficial effects of the utility model are:

[0013] When the material impacts the bottom of the silo, the device can unload the force through the buffer cone and divert it to various material chutes. Generally, 2-5 material chutes can be set. After the material flows to the bottom through the material chute, the discharge valve can be controlled to open and close to release the material for loading. In this process, according to the size of the conveyor material flow, the various material chutes can be discharged in rotation or at the same time to achieve continuous loading operations of the transport vehicle. In order to avoid material accumulation and blockage in the material chute during production and use, it is necessary to release the air cannon in time to impact and clean the accumulated material. As mentioned above, the device can be used to buffer and divert the conveyor conveying materials to achieve the purpose of directly loading the conveyor conveyed materials.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. Example 1

[0024] like Figures 1 to 6 As shown, the prior art in this embodiment has the following problems: The inventors found that if the materials can be divided and transported when the mining conveyor transports them, it will save a lot of manpower and material resources. However, in medium and large open-pit mines, due to the large amount of waste rock or ore required for stripping, conveyors with large transportation capacity and fast running speed are often required. Therefore, the impact force of the materials transmitted from the conveyor port will be very large, and the force surface of the material impact point is wide, so it is impossible to directly load and transport them;

[0026] The effect and principle are as follows: when the material transported by the conveyor 15 is thrown by the conveyor 15, the material impacts the buffer cone 3 at the bottom of the silo body 1 to unload the force, and is diverted by the buffer cone 3 to each material chute 6. Generally, 2-5 material chutes 6 can be set. After the material slides to the bottom through the material chute 6, the discharge valve 10 can be controlled to open and close to release the material for loading. In this process, according to the size of the material flow conveyed by the conveyor 15, each material chute 6 can be discharged in turn or at the same time to realize continuous loading operation of the transport vehicle. In order to avoid material accumulation and blockage in the material chute 6 during production and use, it is necessary to release the air cannon 4 in time to impact and clean the accumulated material; as mentioned above, the device can be used to buffer and divert the material transported by the conveyor 15, so as to achieve the purpose of directly loading the material transported by the conveyor 15.
