Description

Technical Field

[0001] This application belongs to the field of coal mine production technology, specifically relating to a mine vertical and horizontal material conveying system. Background Technology

[0002] With the continuous development of coal mining technology, the depth of coal seam mining is constantly increasing, and the scope of underground construction is gradually expanding, leading to a significant extension of underground auxiliary transportation lines. In the construction processes such as underground roadway support and equipment foundation pouring, concrete, as a core building material, directly determines the project progress and structural safety through its transportation efficiency and quality. However, current deep-well mining scenarios still rely on the traditional long-distance vehicle transfer mode from surface mixing to underground. This mode suffers from the limitations of the underground environment, such as confined space, limited lighting, and complex conditions like roof water seepage and undulating roadways. Long-distance concrete transportation requires multiple tanker trucks to relay the load, and the transportation route involves multiple turning and intersection points, with frequent vehicle starts, stops, and intersections easily causing collisions. Concrete is a homogeneous material composed of cement, sand, gravel, water, and other components mixed in a specific ratio, and its performance depends on the stable proportions of each component. During traditional long-distance vehicle transport, the bumpy ride of the tanker truck can cause the aggregate and mortar inside the concrete to separate into layers. The aggregate, due to its higher density, sinks to the bottom of the tank, while the mortar floats to the surface. The uniformity of the separated concrete is severely reduced, which can lead to quality problems such as insufficient strength and cracks after construction. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] See also Figure 1-3 As shown, an embodiment of this application provides a mine vertical conveying system, comprising: A feeding hopper 1 is located on the ground, and a mine shaft is formed in the ground. Material conveying hole 2, which is drilled vertically from the material discharge hopper 1 located on the ground to the mine shaft; Storage hopper 3, which is set inside the mine, is used to store the material fed into the conveying hole 2; Feeding unit 4, the feeding unit 4 is used to feed materials into the discharge funnel 1; Transfer unit 5: The material in the storage funnel 3 is fed into the transfer unit 5, and the transfer unit 5 is used to transfer the material to the target location.

[0022] In this technical solution, the mine vertical material conveying system provided in this application includes a discharge hopper 1, a conveying orifice 2, a storage hopper 3, a feeding unit 4, and a transfer unit 5. When materials such as concrete need to be conveyed underground in a coal mine, the material can be conveyed to the discharge hopper 1 on the ground through the feeding unit 4. The discharge hopper 1 will feed the material into the conveying orifice 2, and then the material will fall directly into the storage hopper 3 in the mine along the vertically set conveying orifice 2. Compared with the traditional method of mixing the material through ground devices and then transporting the material from the ground to the mine by vehicles over long distances, this application significantly shortens the material transportation path by vertically conveying the material through the conveying orifice 2, reducing the safety hazards caused by frequent vehicle intersections and bumps underground. The storage hopper 3 can temporarily store the falling material, and then feed the stored material into the transfer unit 5, which will finally transfer the material to the underground construction target location. It can effectively solve the problems of material segregation, low efficiency and high safety risks in traditional long-distance transportation. Vertical material conveying reduces the bumps of materials during transportation, reduces the probability of concrete aggregate and mortar segregation, ensures material performance, and eliminates the need for relay transportation of multiple underground transfer vehicles, reducing vehicle and human resource consumption and improving conveying efficiency.

[0023] It is understandable that a conveying pipe can be installed inside the conveying hole 2 to improve the material conveying efficiency.

[0024] Understandably, the specific form of the feeding unit 4 can be selected according to the ground construction conditions. It can be a concrete storage tank with automatic unloading function or a ground transport tanker, as long as it can stably feed material to the downward material funnel 1. The transfer unit 5 is usually selected from underground special transport tankers.

[0025] It is understandable that the diameter of the feed hole 2 is sufficient to allow the material to enter smoothly.

[0026] In some feasible embodiments, a buffer 6 is also included, the buffer 6 comprising: The material discharge pipe 61 has an internal discharge channel. The material discharge pipe 61 is detachably installed at the top of the mine shaft. The discharge channel is connected to the material conveying hole 2. A first baffle 62 is disposed within the discharge channel; The second baffle 63 is disposed in the discharge channel and is angled to the first baffle 62.

[0027] In this technical solution, the buffer 6 includes a discharge pipe 61, a first baffle 62, and a second baffle 63. The first baffle 62 and the second baffle 63 are angled within the discharge pipe 61. When material is conveyed into the mine from the conveying hole 2, it enters the discharge pipe 61 of the buffer 6. Since the conveying hole 2 is vertical, the material falling from the ground experiences a significant impact due to gravity. If it falls directly into the storage hopper 3 below, it can easily cause wear and deformation of the inner wall of the storage hopper 3. Furthermore, the intense impact may cause segregation of aggregates and mortar in the concrete, affecting material quality. Installing the first baffle 62 and the second baffle 63 within the discharge pipe 61 slows down the material's descent, allowing it to exit the discharge pipe 61 at a gentler speed and fall into the storage hopper 3. This avoids impact damage to the storage hopper 3, reduces the probability of material segregation, and ensures the stability of the materials used in subsequent construction.

[0028] In some feasible embodiments, the buffer 6 further includes: The third baffle 64 is disposed on the inner wall of the feed pipe 61 between the first baffle 62 and the second baffle 63.

[0029] In this technical solution, the buffer 6 also includes a third baffle 64. The third baffle 64 is disposed on the inner wall of the feed pipe 61 between the first baffle 62 and the second baffle 63. When the material enters the space enclosed by the first baffle 62, the second baffle 63 and the feed pipe 61, the third baffle 64 can further buffer the material, slow down the falling speed of the material, and prevent the material from directly impacting and entering the storage funnel 3.

[0030] It is understandable that the cross-sectional length of the third baffle 64 is smaller than the inner radius of the feed pipe 61. Therefore, one end of the third baffle 64 is connected to the inner wall of the feed pipe 61, and the other end is located in the space enclosed by the first baffle 62, the second baffle 63 and the feed pipe 61. While further buffering the material, it can also enhance the mixing of the material entering the storage funnel 3 by resisting it.

[0031] In some feasible embodiments, the first baffle 62 and the second baffle 63 are arranged perpendicularly.

[0032] In this technical solution, by limiting the first baffle 62 and the second baffle 63 to be set perpendicularly, the impact force of the material from the feed hole 2 can be dispersed more evenly, so that the material falling into the storage funnel 3 is more uniform.

[0033] In some feasible embodiments, a plurality of fixing ears are provided at intervals on the outer circumference of the feed pipe 61, and a connecting rope is provided between the fixing ears and the top of the mine.

[0034] In this technical solution, multiple fixing ears are installed at intervals on the outer circumference of the feed pipe 61. The fixing ears are provided with through holes 72, through which the connecting rope can be passed. Then, the other end of the connecting rope is fixed to the top of the mine by bolts to fix the feed pipe 61. At the same time, it is also easy to disassemble and replace the buffer 6.

[0035] It is understandable that there are four fixing ears, which are symmetrically installed in pairs on the outer circumference of the feed tube 61 to achieve stable fixing of the buffer 6.

[0036] In some feasible embodiments, an anti-blocking device 7 is also included, which is disposed on the inlet of the feeding funnel 1 and the storage funnel 3. The anti-blocking device 7 includes an anti-blocking plate 71 and through holes 72, and a plurality of through holes 72 are spaced apart on the anti-blocking plate 71.

[0037] In this technical solution, anti-blocking devices 7 are installed at the inlets of the feeding hopper 1 and the storage hopper 3, respectively. At the ground end, when the feeding unit 4 conveys material to the feeding hopper 1, the material must first pass through the anti-blocking device 7 before entering the feeding hopper 1. The through holes 72 on the anti-blocking plate 71 can filter out large impurities mixed in the material, allowing only materials that meet the particle size requirements to enter the feeding hopper 1 through the through holes 72, thus preventing large impurities from clogging the outlet of the feeding hopper 1 or the subsequent vertical conveying hole 2, ensuring smooth material conveying at the ground end. At the underground end, before the material falling through the conveying hole 2 enters the storage hopper 3, it must pass through the anti-blocking device 7 at the inlet of the storage hopper 3. At this time, the anti-blocking device 7 can filter out large particles of impurities in the material a second time, preventing large particles of impurities from clogging the outlet of the storage hopper 3, ensuring that the storage hopper 3 can stably supply material to the transfer unit 5, and avoiding material interruption during underground construction due to blockage.

[0038] In some feasible embodiments, the inlets of the feeding funnel 1 and the storage funnel 3 are provided with a fixing frame, and the anti-blocking device 7 is detachably mounted on the fixing frame.

[0039] In this technical solution, a fixing frame is installed on the inlet of both the feeding hopper 1 and the storage hopper 3. The fixing frame is used to install the anti-blocking device 7. The anti-blocking device 7 can be detachably installed on the fixing frame, which makes it easy to replace the anti-blocking device 7.

[0040] In some feasible embodiments, a fixed platform 8 is also included, which is disposed within the mine, and the storage hopper 3 is disposed on the fixed platform 8.

[0041] In this technical solution, the fixed platform 8 is installed inside the mine. The fixed platform 8 is used to fix the storage hopper 3. The fixed platform 8 can lift the storage hopper 3 to a certain height. A discharge valve is provided at the bottom of the storage hopper 3, which facilitates the transfer unit 5 to move to the bottom of the storage hopper 3 to carry the material, making it convenient to transfer the material and improve the unloading efficiency.

[0042] The feeding unit 4 is a storage tank or a transport tanker truck.

[0043] The transfer unit 5 is a transport tanker truck.

The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
