Description

Technical Field

[0001] This utility model relates to the field of chemical mining and conveying equipment technology, specifically to an integrated milling and conveying machine for potash ore. Background Technology

[0002] Potash is an important chemical raw material with an irreplaceable role in agricultural production. Traditional potash mining, especially the mining of shallow, soft potash deposits, typically employs a multi-machine, step-by-step operation. First, milling machines, excavators, or specialized mining machines are used to remove the ore from the ore body. Then, loaders and trucks transport the crushed ore to a designated mixing tank or processing point. At the mixing point, water or other solvents are added to the ore, and through stirring and crushing processes, a pumpable slurry is created. Finally, pumps and pipelines are used to transport the slurry to the next processing stage.

[0003] The aforementioned traditional step-by-step mining process has significant drawbacks: First, it relies on various equipment and a large amount of manpower for coordination and transfer between different processes, resulting in a discontinuous production flow, low automation, and overall low mining efficiency. Second, the large variety and quantity of equipment required not only increases initial purchase costs but also enhances the complexity of operation, management, and maintenance. Third, material spillage and dust are easily generated during loading, unloading, and transfer, polluting the mining area and causing material loss. Finally, the decentralized operation requires a large work area, which is not conducive to flexible deployment in narrow or geologically complex mining areas.

[0004] Therefore, there is an urgent need in this field for an integrated equipment that can combine milling, slurry preparation and conveying functions to simplify the process, improve mining efficiency, reduce overall costs and improve the working environment. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing an integrated milling and conveying machine for potassium salt mines.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: an integrated milling and conveying machine for potassium salt mines, including a traveling chassis, on which a milling mechanism, a slurry preparation mechanism and a conveying pump are integrated. The discharge port of the milling mechanism corresponds to the inlet of the slurry preparation mechanism, and the discharge port of the slurry preparation mechanism is connected to the input end of the conveying pump.

[0007] Preferably, a first flexible pipe is installed at the output end of the delivery pump, a positioning vehicle is hinged to the rear of the walking chassis, a plurality of pipe brackets are hinged sequentially to the rear of the positioning vehicle, a moving wheel assembly is installed at the bottom of the pipe brackets, the first flexible pipe is supported on the positioning vehicle and the plurality of pipe brackets, and a second flexible pipe is connected to the slurry adjustment mechanism, the second flexible pipe being supported on the positioning vehicle and the pipe brackets.

[0008] Preferably, the discharge port of the milling mechanism is a throwing port, the inlet of the slurry preparation mechanism is a receiving hopper, and the throwing port and the receiving hopper are connected by a belt conveyor or a chute.

[0009] Preferably, the milling mechanism includes a milling machine body and a milling head, with the milling head disposed in front of or at the bottom of the milling machine body.

[0010] Preferably, the chassis is a tracked chassis or a wheeled chassis.

[0011] Preferably, both the pipe bracket and the positioning vehicle are equipped with clamping components, and the first flexible pipe and the second flexible pipe are clamped by the clamping components.

[0012] Preferably, the first flexible pipe fitting and the second flexible pipe fitting are both HDPE100 steel-plastic composite pipe, PC1000 ultra-high molecular weight pipe, neoprene rubber reinforced hose or nitrile rubber steel wire reinforced hose.

[0013] Preferably, both the first flexible pipe fitting and the second flexible pipe fitting include a second pipe that connects the first pipe to the first pipe. The first pipe is an HDPE100 steel-plastic composite pipe and / or a PC1000 ultra-high molecular weight pipe, and the second pipe is a neoprene rubber reinforced hose and / or a nitrile rubber steel wire reinforced hose.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This integrated milling and conveying machine for potash ore integrates three major functional modules—milling mechanism, slurry preparation mechanism, and conveying pump—on the same chassis, forming a compact and mobile integrated working unit. After being crushed by the milling mechanism, the potash ore can enter the slurry preparation mechanism through the discharge port, eliminating the intermediate connection links such as truck transfer, intermediate storage, and secondary loading and unloading in the traditional process. It realizes the connection of the three core processes of milling, slurry preparation, and pumping, greatly reducing non-operating time and increasing output per unit time.

[0016] 2. This integrated milling and conveying machine for potash mines simplifies the equipment system and effectively reduces overall costs. One integrated machine replaces the functions of a system that originally required multiple independent pieces of equipment, such as milling machines, transfer vehicles, fixed slurry preparation equipment, and conveying pump stations. This not only reduces initial equipment investment but also lowers subsequent operation and maintenance costs, manpower requirements, and equipment management complexity.

[0017] 3. This integrated milling and conveying machine for potash ore allows materials to flow within a relatively closed integrated system, reducing problems such as material spillage and dust pollution caused by traditional transfer methods. This not only reduces the loss of valuable potash ore but also meets the requirements of green and environmentally friendly mining. At the same time, the integrated design enhances the overall mobility of the equipment, enabling it to more flexibly adapt to the needs of advancing and relocating the working face in the mining area.

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please refer to Figures 1 to 3 The integrated milling and conveying machine for potash ore in this solution includes a traveling chassis 1, on which a milling mechanism 2, a slurry preparation mechanism 3 and a conveying pump 4 are integrated. The discharge port of the milling mechanism 2 corresponds to the inlet of the slurry preparation mechanism 3, and the discharge port of the slurry preparation mechanism 3 is connected to the input end of the conveying pump 4 through a discharge pipe 32.

[0024] By integrating the three major functional modules of milling mechanism 2, slurry preparation mechanism 3 and conveying pump 4 onto the same traveling chassis 1, a compact and mobile integrated operation unit is formed. After being crushed by milling mechanism 2, potash ore can enter slurry preparation mechanism 3 through the discharge port, eliminating the intermediate connection links such as truck transfer, intermediate storage and secondary loading and unloading in the traditional process. This realizes the connection of the three core processes of milling-slurry preparation-pumping, which greatly reduces non-operation time and increases the output per unit time.

[0025] Meanwhile, the integrated machine design effectively reduces overall costs. One integrated machine replaces the system functions that originally required multiple independent pieces of equipment, such as a milling machine, a transfer vehicle, a fixed slurry preparation device, and four delivery pump stations. This not only reduces initial equipment investment but also lowers subsequent operation and maintenance costs, manpower requirements, and equipment management complexity.

[0026] Because materials flow within a relatively closed integrated system, problems such as material spillage and dust pollution caused by traditional transfer methods are reduced. This not only minimizes the loss of valuable potash ore but also meets the requirements of green and environmentally friendly mining. At the same time, the integrated design enhances the overall mobility of the equipment, enabling it to adapt more flexibly to the needs of advancing and relocating the mining face.

[0027] Preferably, a first flexible pipe 5 is installed at the output end of the delivery pump 4, a positioning vehicle 6 is hinged to the rear of the walking chassis 1, a plurality of pipe brackets 7 are sequentially hinged to the rear of the positioning vehicle 6, a moving wheel assembly 8 is installed at the bottom of the pipe brackets 7, the first flexible pipe 5 is supported on the positioning vehicle 6 and the plurality of pipe brackets 7, and a second flexible pipe 11 is connected to the slurry adjustment mechanism 3, the second flexible pipe 11 is supported on the positioning vehicle 6 and the pipe brackets 7.

[0028] The first flexible pipe fitting 5 is used to transport the mixed solid-liquid mixture out of the slurry preparation mechanism 3, and the second flexible pipe fitting 11 is used to transport the liquid required for slurry preparation from an external water source or storage equipment to the slurry preparation mechanism 3. Inside the slurry preparation mechanism 3, the liquid is mixed with the solid potassium salt ore input from the milling mechanism 2 to form a pumpable slurry.

[0029] By installing a first flexible pipe fitting 5 at the output end of the conveying pump 4, and hinged a positioning vehicle 6 and multiple pipe brackets 7 with moving wheel assemblies 8 at the rear of the traveling chassis 1, the technical effect is to achieve synchronous movement and orderly support of the conveying pipeline. This design allows the conveying pipeline behind the integrated machine to move along with the main unit when the machine is moving forward, avoiding the problems of pipe twisting, pulling, or even damage caused by the pipeline remaining stationary while the main unit moves forward. The hinged positioning vehicle 6 and pipe brackets 7 can adapt to uneven ground, maintain the smoothness of pipeline laying, and reduce the resistance to pipeline movement. The design of the moving wheel assembly 8 facilitates the flexible turning and movement of the entire pipeline system with the main unit, ensuring the stable operation of long-distance, continuous conveying operations.

[0030] It should be noted that the positioning vehicle 6 is equipped with a controller 12 and a positioner. The controller 12 is used to control the positioning vehicle 6 to turn. The pipe bracket 7 is equipped with a positioner to display the position of the pipe bracket 7 in real time. The moving wheel assembly 8 of the positioning vehicle 6 can have four moving wheels, and the moving wheel assembly 8 of the pipe bracket 7 can have two moving wheels. The pipe bracket 7 and the positioning vehicle 6, as well as the pipe brackets 7, are all connected by ball joints. An additional delivery pump can be installed on the traveling chassis 1, or an additional delivery pump can be installed at the end of the second flexible pipe 11 away from the slurry adjustment mechanism 3 to deliver the liquid in the second flexible pipe 11, thereby providing power for the liquid delivery.

[0031] Preferably, the discharge port of the milling mechanism 2 is a throwing port 21, and the feed port of the slurry preparation mechanism 3 is a receiving hopper 31. The throwing port 21 and the receiving hopper 31 are connected by a belt conveyor mechanism 92 or a chute 91.

[0032] When the discharge port 21 is above the receiving hopper 31, a chute 91 can be used to guide and transport the material, utilizing the material's gravitational potential energy to achieve natural material drop. This structure is simple and reliable, and can complete the material transfer from milling to slurry preparation without an additional power conveying mechanism, reducing the complexity and energy consumption of the equipment. When the discharge port 21 is below the receiving hopper 31, a belt conveyor mechanism 92 connects the discharge port 21 and the receiving hopper 31, enabling the lower material to overcome gravity and be transported to a higher position. At the same time, the belt conveyor mechanism 92 can provide a more controllable conveying speed.

[0033] The slurry preparation mechanism 3 is equipped with a crushing device (not shown in the figure). The crushing device can be a stirring blade or a crushing cutter head. This application has not made any improvements to it.

[0034] The crushing unit can further crush and disperse potash ore with uneven dimensions after milling, preventing large pieces of material from clogging subsequent pumping pipelines and ensuring that the produced slurry has uniform particle size to meet pumping requirements. The feed pipe allows the slurry preparation process to be completed directly on this equipment, enabling precise control of water addition based on ore characteristics and conveying requirements, and timely preparation of slurry with appropriate concentration to provide a qualified fluid medium for subsequent pipeline transportation.

[0035] Please refer to Figure 1 and Figure 3 Preferably, the milling mechanism 2 includes a milling machine body 22 and a milling head 23. The milling head 23 is located in front of or at the bottom of the milling machine body 22. Specifically, the milling mechanism 2 can be one of a road milling machine, a combined coal mining machine, a tunneling machine, a milling machine, a loader, or a milling and polishing machine.

[0036] In the above technical solution, when the milling head 23 is installed in front of the milling machine body 22, the milling machine can easily mill and mine the ore in front of the device. When the milling head 23 is installed at the bottom of the milling machine body 22, the milling head 23 can mine the ore located below the device. Users can flexibly select the most suitable milling mechanism 2 according to the specific hardness, milling thickness and other working conditions of the potash ore layer, so that the integrated machine can adapt to the operation requirements under different mining conditions, and improve the versatility of the equipment and the feasibility of the technical solution.

[0037] Preferably, the chassis 1 is a tracked chassis or a wheeled chassis.

[0038] Tracked chassis have low ground pressure, providing excellent off-road and passability, making them suitable for soft, muddy, or uneven mining surfaces. Wheeled chassis, on the other hand, offer advantages such as high mobility, flexible steering, and minimal damage to the road surface, making them suitable for mining areas with better ground conditions and requiring frequent and rapid relocation. This design allows users to choose the most suitable mode of transport based on actual working conditions, optimizing equipment efficiency and mobility.

[0039] Please refer to Figure 2 Preferably, both the pipe bracket 7 and the positioning vehicle 6 are provided with clamping components 10, and the first flexible pipe 5 and the second flexible pipe 11 are clamped by the clamping components 10.

[0040] In the above scheme, the clamping component 10 can clamp the first flexible tube 5 and the second flexible tube 11, thereby preventing the first flexible tube and the second flexible tube from being fixed and preventing them from swinging or vibrating randomly under the action of external force.

[0041] Preferably, the first flexible pipe fitting 5 and the second flexible pipe fitting 11 are both HDPE100 steel-plastic composite pipe, PC1000 ultra-high molecular weight pipe, neoprene rubber reinforced hose or nitrile rubber steel wire reinforced hose.

[0042] Among the above options, chloroprene rubber has good chemical corrosion resistance, can withstand the slight chemical erosion of potash slurry, and has strong aging resistance and tear resistance. When combined with steel wire or fiber skeleton, it can withstand high pumping pressure while maintaining good flexibility and is not prone to cracking due to equipment relocation or ground bumps. Nitrile rubber has good oil resistance and weak chemical corrosion resistance, and excellent elasticity. It easily returns to its original shape after bending. When combined with steel wire skeleton, it has strong pressure bearing capacity and can withstand long-term friction from solid particles in slurry.

[0043] Preferably, both the first flexible pipe fitting 5 and the second flexible pipe fitting 11 include a second pipe that connects the first pipe to the first pipe. The first pipe is an HDPE100 steel-plastic composite pipe and / or a PC1000 ultra-high molecular weight pipe, and the second pipe is a neoprene rubber reinforced hose and / or a nitrile rubber steel wire reinforced hose.

[0044] In the above solution, wear-resistant materials can effectively reduce frictional loss between the outer wall of the pipe and the support groove, and extend the service life of the pipe. HDPE100 steel-plastic composite pipe and PC1000 ultra-high molecular weight pipe have a large radius of curvature when bent, while neoprene rubber reinforced hose and nitrile rubber steel wire reinforced hose have a small radius of curvature when bent. Therefore, the main body of the flexible pipe fitting can be made of HDPE100 steel-plastic composite pipe and / or PC1000 ultra-high molecular weight pipe, while neoprene rubber reinforced hose and / or nitrile rubber steel wire reinforced hose can be used where large bending is required.

[0045] Work style:

[0046] At the start of operation, the integrated machine, powered by the traveling chassis 1, travels to the front of the potash mine work area. Depending on the geological conditions of the mining area, a tracked or wheeled chassis can provide appropriate mobility and passability. At this time, the milling mechanism 2 located on the traveling chassis 1 starts working, and the milling head 23 on the milling mechanism 2 cuts and crushes the ore layer, stripping the solid potash ore from the ore body.

[0047] The potash ore fragments that have been planed off are ejected from the discharge port by the throwing device of the milling mechanism 2. Under the action of gravity, the ejected material falls into the receiving hopper 31 of the slurry preparation mechanism 3 located below it. To achieve a smoother conveying, the material can also be transferred through an intermediate belt conveyor mechanism 92 or chute 91 before entering the receiving hopper 31. This effectively prevents material splashing and ensures the accuracy of feeding.

[0048] After the material enters the slurry preparation mechanism 3, the second flexible pipe 11 inputs the liquid into the slurry preparation mechanism 3 through the delivery pump 4. At the same time, the crushing device inside the slurry preparation mechanism 3 operates to further crush, stir and homogenize the mixture, and fully mix the solid potassium salt ore with water to prepare a slurry with appropriate concentration and good fluidity.

[0049] Finally, the prepared slurry enters the conveying pump 4 through the discharge pipe 32. The conveying pump 4 provides the conveying power for the slurry, pumping it into the first flexible pipe 5 connected to the output end. As the integrated machine continues to move forward, the positioning vehicle 6, hinged to the rear of the chassis 1, and multiple subsequent pipe supports 7, supported by the moving wheel assembly 8, move in coordination with the main machine, thereby orderly supporting and guiding the first flexible pipe 5 and the second flexible pipe 11, allowing them to extend with the main machine and achieve long-distance, uninterrupted slurry transportation until the slurry is delivered to the designated collection point or processing station.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
