Description

Technical Field

[0001] The invention belongs to the technical field of underground mine mining system equipment, and in particular relates to an automatic cleaning engineering vehicle for underground mine water tanks. Background Art

[0002] During underground mining, water from each production section is collected at the lowest level through ditches and drainage wells and flows into the main water tank. Water brings mud and sand in the process of collection. After entering the water tank, the mud and sand gradually settle and accumulate as the flow rate decreases. Finally, the clean water is discharged from the pump room at the end of the water tank. The precipitated mud and sand have their specific characteristics, mainly small particles, but because the water is mixed with cementing materials filtered out of the underground filling body, such as cement, some of the mud and sand will condense into a certain amount of compacted materials, but the hardness of the compacted materials is relatively small. If the mud and sand are not cleaned up in time, it will affect the work of the subsequent drainage pump. Due to the characteristics of the sediment, it is difficult to use a specific pump or other machinery to clean it all at once. So far, there is no equipment on the market that is specifically suitable for this type of sediment characteristics.

[0003] When the silt in the water tank accumulates to 1 / 2 to 3 / 4 of the cross-section of the water tank tunnel, it must be cleaned. At present, there are two ways to clean most mines: one is mainly manual, where the mud and sand are manually loaded into woven bags or transported out by mine cars, sometimes assisted by small scrapers. The working environment is poor, the intensity is high, and the cleaning cost is very high; the other method is to dilute the mud and make a simple pontoon. A small vertical long-axis slurry pump is installed on the pontoon to discharge the mud to the subsequent sedimentation tank for further treatment. It also requires manual traction of the pontoon and manual dilution of the mud and sand on the working face. The degree of automation is low and the above problems of manual cleaning also exist. Both methods have no good way to deal with large blocks of compaction. After cleaning, secondary operations are often required. The manual secondary operation removes large blocks. Each operation takes a very long time, which delays the precious production time of the mine.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0009] The scrapping mechanism is located at the front end of the vehicle body, and the scrapping mechanism scrapes the mud and sand in front of the vehicle body in the water sump level tunnel into the chain bucket conveying mechanism;

[0010] The chain bucket conveying mechanism connects the slag removing mechanism and the vibration screening mechanism;

[0011] The vibrating screening mechanism has a belt transfer mechanism under the screen, and the vibrating screening mechanism has an outlet on the screen connected to a crushing mechanism;

[0029] The working principle of an automatic cleaning vehicle for underground mine water tanks provided by the embodiment of the present invention is described as follows:

[0030] The clean water in the water tank is discharged in advance by a small pump, so the water tank is basically filled with silt sediment. The engineering vehicle enters the water tank lane through the walking mechanism. The slag removal mechanism is installed at the front end of the vehicle body, which can form a 30° swing angle to the left and right along the travel direction, and can basically cover all the sediments in the water tank section. The slag removal mechanism removes the silt (including large pieces) accumulated in front of the vehicle body into the chain bucket conveying mechanism at the lower front end of the vehicle. The chain bucket conveying mechanism operates to transport the removed silt to the vibrating screen installed in the middle of the vehicle body.

[0031] The vibrating screen has both screening and vibration functions. While vibrating, small pieces of sand and mud can fall directly from the mesh of the vibrating screen to the belt transfer mechanism at the bottom, and large pieces of material can be shaken to the crushing mechanism at the rear through the vibrating screen. A guide trough can be added between the vibrating screen and the crushing mechanism according to the situation to prevent large pieces of material from spilling. Since there are not many large pieces and the hardness is not high, a small crusher can meet the crushing requirements. The mesh diameter of the vibrating screen and the crushing size of the crushing mechanism are controlled according to the conveying particle size allowed by the subsequent slurry conveying mechanism.

[0032] After the large pieces of compacted materials are broken, they also fall to the belt conveyor at the bottom. The belt conveyor transports and unloads the mud and sand mixture that meets the subsequent discharge particle size requirements to the rear stirring and shaking barrel. A dilution water supply device is installed on the top of the mixing barrel. After the mud and sand are mixed with water in the barrel, they are stirred by the stirring device to ensure that the mass concentration of the slurry in the barrel is about 50% (it can be adjusted according to the mass concentration required by the slurry conveying mechanism) and then discharged by the slurry conveying mechanism.

[0033] The embodiment of the present invention provides an integrated design of an underground mine water tank automatic cleaning engineering vehicle, which integrates multiple functions in one, and can realize mechanical automatic scrapping, conveying, vibration, screening, crushing, dilution mixing and conveying functions, with strong pertinence and applicability, and especially considers the bulk processing link. In addition, the front and rear connection and coordination relationship of various mechanisms in the engineering vehicle can process small particles and compacted bulk materials at one time.

[0034] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0035] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0036] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
