[0001] The present invention relates to the technical field of ore raw material transportation, in particular to an ore raw material transportation device. Background Art

[0002] In the field of ore mining and processing, ore raw material conveying equipment plays a vital role. After the ore is excavated from the mining site, it needs to be transported by conveying equipment to various processing links, such as crushing, screening, and smelting. The stable operation of ore raw material conveying equipment is directly related to the efficiency and cost of the entire ore processing process. With the continuous development of the ore industry, the demand for ore raw material conveying equipment is also increasing. The requirements for conveying capacity, conveying distance, and adaptability to different ore characteristics are also constantly improving. Various conveying devices, such as belt conveyors and scraper conveyors, are widely used in ore raw material transportation, providing strong support for the normal operation of the ore industry.

[0003] However, most of the current ore raw material conveying devices lack an effective dust-blocking structure. During the ore conveying process, friction and collision between the ore and the conveying equipment, as well as wind and other factors, will generate a large amount of dust. This dust not only spreads wantonly in the working environment, seriously affecting the health of the operators. Operators who are in such an environment for a long time are very likely to suffer from respiratory diseases, pneumoconiosis and other occupational diseases; it will also cause damage to surrounding equipment. For this reason, the present invention provides an ore raw material conveying device. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides an ore raw material conveying device, which solves the problem that most current ore raw material conveying devices lack an effective dust-blocking structure, and a large amount of dust is generated during the ore conveying process. This dust not only spreads wantonly in the working environment, seriously affecting the health of the operators, but also causes damage to surrounding equipment.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an ore raw material conveying device, including a conveying platform, and also including: A mounting frame and a water injection unit, wherein the mounting frame can be detachably mounted on the upper portion of the conveying platform, and the water injection unit is connected to the lower portion of the top of the mounting frame and is used to introduce an external water source; A dust barrier unit, which is connected to the water injection unit and is deployed to cover the upper end space of the conveying platform after water is injected into the dust barrier unit through the water injection unit; The dust reduction unit is connected to the lower part of the water injection unit, and water is injected into the dust reduction unit through the water injection unit to spray the ore raw materials on the conveying platform to reduce dust.

[0006] Preferably, the mounting frame includes a cross bar and a cavity block, the cavity block is fixed to the upper end of the cross bar, and a rotary rod is rotatably mounted on the upper end of the cavity block, and a first bevel gear is fixed to the bottom of the rotary rod.

[0007] Preferably, screws are rotatably mounted on both sides of the cavity block, the screws extend to the inner end of the cavity block where a second bevel gear meshing with the first bevel gear is fixed, and the other end of the screws is threadedly connected to a threaded sleeve.

[0008] Preferably, a T-shaped slider is integrally formed at the lower end of the threaded sleeve rod, and the T-shaped slider slides horizontally along the T-shaped groove provided on the upper surface of the cross bar. A clamping rod is fixed to the end of the threaded sleeve rod for clamping with the conveying platform.

[0009] Preferably, the water injection unit includes a filling cylinder fixed to the lower end of the cross bar, and the two ends of the filling cylinder are interconnected with a water inlet pipe and a drain pipe. The outlet of the drain pipe is closed by a pipe cover, and a pump and a control valve are installed on the water inlet pipe.

[0010] Preferably, the two sides of the lower part of the drainage pipe are interconnected with guide tubes, a piston is slidably installed on the inner wall of the filling cylinder, a spring is connected between the piston and the bottom wall inside the filling cylinder, and the spring is squeezed by the water pressure inside the filling cylinder to cause the piston to drop, and then the water source inside the filling cylinder flows into the dust reduction unit through the guide tube.

[0011] Preferably, the dust shielding unit includes a filling frame, which is interconnected with the upper portion of the filling cylinder. The filling frame is specifically made of synthetic rubber material, and a dust shielding cloth is bonded to the filling frame.

[0012] Preferably, the dust reduction unit includes a water distribution plate, the water distribution plate is connected to the guide tube, and a plurality of groups of sprinkler heads are installed on the bottom of the water distribution plate.

[0013] The present invention provides an ore raw material conveying device. Compared with the prior art, it has the following beneficial effects: 1. This ore raw material conveying device is designed with a dust shield unit. The filling frame is made of a flexible and expandable synthetic rubber material. When the water injection unit injects water into the filling frame, the filling frame expands and drives the dust shield adhered to it to unfold, which can completely cover the upper space of the conveying platform and form an effective dust barrier. The special material and structure of the dust shield can greatly prevent the dust generated during the conveying process of ore raw materials from spreading to the surrounding environment, effectively improving the working environment and reducing the harm of dust to the health of operators and pollution to surrounding equipment and the environment. 2. This ore raw material conveying device is designed with a dust suppression unit that cooperates with the water injection unit. As the water level in the filling cylinder rises, the water pressure squeezes the piston to overcome the spring force and descend, allowing water to accurately flow into the water distribution plate of the dust suppression unit through the guide tube. The water distribution plate can evenly distribute the water flow to each sprinkler head. The sprinkler head sprays water on the ore raw material in the form of a fine mist, fully covering the ore surface, effectively reducing the dust generated during the ore transportation process. The entire dust reduction process is automatically controlled by water pressure, without the need for an additional complex power system. The operation is stable and reliable, and the dust reduction effect is good, which improves the environmental performance of the ore transportation process. 3. The ore raw material conveying device features a mounting frame that can be quickly installed and removed from the conveyor platform through a unique clamping structure. The rotating rod is manually rotated, and the bevel gear transmission drives the screw to rotate, causing the threaded sleeve to slide horizontally along the crossbar and finally be firmly clamped on the conveyor platform through the clamping rod. This installation method does not require complex tools and tedious operations, greatly saving installation time and labor costs, while ensuring the stability of the installation and providing reliable protection for the subsequent stable operation of the device.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-7 The present invention provides a technical solution: an ore raw material conveying device, specifically including the following embodiments: Embodiment 1: An ore raw material conveying device includes a conveying platform 1, and also includes: a mounting frame 2 and a water injection unit 3. The mounting frame 2 can be detachably mounted on the upper part of the conveying platform 1. The water injection unit 3 is connected to the lower part of the top of the mounting frame 2 and is used to introduce an external water source; a dust shield unit 4, which is connected to the water injection unit 3 and is expanded to cover the upper end space of the conveying platform 1 after water is injected into the dust shield unit 4 through the water injection unit 3. Specifically, when the water injection unit 3 injects water into the dust shield unit 4, the structure of the dust shield unit 4 The structure will deform and expand due to the injection of water. Its material is soft and has a certain elasticity, which can effectively prevent the dust generated during the ore transportation process from spreading to the surrounding environment; the dust reduction unit 5, the dust reduction unit 5 is connected to the lower part of the water injection unit 3, and water is injected into the dust reduction unit 5 through the water injection unit 3, and then the ore raw materials on the conveying platform 1 are sprayed to reduce dust. A special water flow dispersion structure is provided in the dust reduction unit 5, which can make the water flowing in from the water injection unit 3 evenly sprinkled on the ore raw materials through the spray head, thereby improving the dust reduction effect.

[0018] Embodiment 2: The main difference between this embodiment and the first technical solution is that: an ore raw material conveying device, the mounting frame 2 includes a cross bar 21 and a cavity block 22, the cavity block 22 is fixed to the upper end of the cross bar 21, and the upper end of the cavity block 22 is rotatably mounted with a rotary rod 23, the bottom of the rotary rod 23 is fixed with a first bevel gear 24, screws 26 are rotatably mounted on both sides of the cavity block 22, the screws 26 extend to the inner end of the cavity block 22 and are fixed with a second bevel gear 25 meshing with the first bevel gear 24, and the other end of the screw 26 is threadedly screwed with a threaded sleeve 27, the threaded sleeve 27 A T-shaped slider 28 is integrally formed at the lower end, and the T-shaped slider 28 slides horizontally along the T-shaped groove provided on the upper surface of the cross bar 21. A clamping rod 29 is fixed to the end of the threaded sleeve 27 for clamping the conveyor platform 1. By rotating the rotating rod 23, the first bevel gear 24 is driven to rotate, and then the second bevel gear 25 engaged with it drives the screw 26 to rotate. The threaded sleeve 27 will make a linear motion along the screw 26. The sliding guide of the T-shaped slider 28 in the T-shaped groove allows the two clamping rods 29 to approach or move away from the conveyor platform 1 at the same time, thereby achieving stable clamping of the conveyor platform 1.

[0019] The water injection unit 3 includes a filling cylinder 31 fixed to the lower end of the cross bar 21, and the two ends of the filling cylinder 31 are interconnected with a water inlet pipe 32 and a drain pipe 34. The outlet of the drain pipe 34 is closed by a pipe cover. A pump 33 and a control valve are installed on the water inlet pipe 32, and the two sides of the lower part of the drain pipe 34 are interconnected with a guide pipe 35. A piston 35 is slidably installed on the inner wall of the filling cylinder 31, and a spring 37 is connected between the piston 35 and the bottom wall of the filling cylinder 31. The water pressure inside the filling cylinder 31 squeezes the spring 37 to make the piston 35 move down, and then the water source inside the filling cylinder 31 flows into the dust suppression unit 5 through the guide pipe 35. When the pump 33 works to fill water into the filling cylinder 31 through the water inlet pipe 32, as the water level rises, the water pressure increases, the piston 35 overcomes the elastic force of the spring 37 and moves down, so that the water can flow out stably through the guide pipe 35, and the elastic coefficient of the spring 37 is carefully designed to ensure the stable output of the water flow.

[0020] The dust shield unit 4 includes a filling frame 41, which is interconnected with the upper part of the filling cylinder 31. The filling frame 41 is made of synthetic rubber material, and a dust shield cloth 42 is bonded to the filling frame 41. The filling frame 41 made of synthetic rubber material has good flexibility and sealing properties. After being injected with water, it can expand rapidly, driving the dust shield cloth 42 to unfold. The dust shield cloth 42 adopts a special textile process, and its fibers are fine and can effectively absorb and block fine dust.

[0021] The dust reduction unit 5 includes a water distribution plate 51, which is connected to the guide tube 35, and a plurality of groups of spray heads 51 are installed at the bottom of the water distribution plate 51. The water distribution plate 51 is provided with criss-cross flow channels inside, which can evenly distribute the water flowing in from the guide tube 35 to each spray head 51. The spraying range of the spray head 51 can fully cover the ore raw materials on the conveying platform 1.

[0022] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0023] During operation, the mounting frame 2 is first moved to the predetermined mounting position on the upper part of the conveyor platform 1. The cross bar 21 of the mounting frame 2 needs to be accurately placed in the position adapted to the conveyor platform 1 to provide basic support for subsequent clamping operations. By manually rotating the rotary rod 23, the first bevel gear 24 fixed at the bottom of the rotary rod 23 rotates synchronously. Since the first bevel gear 24 is in meshing state with the second bevel gear 25 at the end of the screw 26 rotatably installed on both sides of the cavity block 22, the rotation of the first bevel gear 24 will drive the second bevel gear 25 and the screw 26 connected to it to rotate together. When the screw 26 rotates, the threaded sleeve 27 threadedly connected to it can only slide linearly in the horizontal direction because the T-shaped slider 28 cooperates with the T-shaped groove set on the upper surface of the cross bar 21. The T-shaped slider 28 slides in the T-shaped slot, which not only ensures the stability of the movement of the threaded sleeve 27, but also limits its movement direction so that it can only move horizontally along the cross bar 21. As the screw 26 continues to rotate, the threaded sleeve 27 continues to approach the conveyor platform 1. When the clamping rod 29 at the end of the threaded sleeve 27 is in close contact with the conveyor platform 1 and provides sufficient clamping force, the mounting frame 2 is firmly installed on the conveyor platform 1, and disassembly and assembly are convenient. Then, reliably connect the water inlet pipe 32 of the water injection unit 3 to the external water source, and ensure that the connection parts are well sealed to prevent water leakage. The water inlet pipe 32 provides a channel for the water source to enter the device. Open the control valve installed on the water inlet pipe 32. The control valve is used to adjust and control the on-off and flow rate of the water flow. Start the pump 33. The pump 33 serves as a power source and provides sufficient pressure for the transportation of the water source, so that the external water source flows into the filling cylinder 31 through the water inlet pipe 32. As the pump 33 continues to work, the water level in the filling cylinder 31 gradually rises. When the water level reaches a certain height, the water source flows into the dust barrier through the filling frame 41 interconnected with the upper part of the filling cylinder 31. Unit 4, the structural design of the filling frame 41 enables it to effectively guide the flow of water. The filling frame 41 is made of a synthetic rubber material with good flexibility and expandability. When water flows into the filling frame 41, the filling frame 41 expands and deforms due to the internal filling of water. Since the dust cover 42 is firmly bonded to the filling frame 41, the expansion of the filling frame 41 drives the dust cover 42 to unfold synchronously. After the dust cover 42 is unfolded, it can completely cover the space above the conveyor platform 1, forming a barrier to prevent the spread of dust. The material and structural design of the dust cover 42 give it excellent dustproof performance, which can effectively prevent the dust generated during the transportation of ore raw materials from spreading to the surrounding environment. As the water level in the filling cylinder 31 rises further, the water pressure in the cylinder gradually increases. The increased water pressure acts on the piston 35, squeezing the spring 37 connected between the piston 35 and the bottom wall of the filling cylinder 31. The spring 37 is elastically deformed when subjected to the water pressure. The piston 35 overcomes the elastic force of the spring 37 under the continuous action of the water pressure and gradually descends. During the descending process of the piston 35, the water source in the filling cylinder 31 flows into the dust suppression unit 5 through the guide tubes 35 interconnected on both sides of the lower part of the filling cylinder 31. The setting of the guide tubes 35 ensures that the water source can be accurately and smoothly The water is guided from the filling cylinder 31 to the dust reduction unit 5. The water distribution plate 51 of the dust reduction unit 5 is connected with the guide pipe 35. The water flowing into the guide pipe 35 smoothly enters the water distribution plate 51. The water distribution plate 51 plays a role in evenly distributing the water flow, so that the water source can reach all parts evenly. Several groups of spray heads 52 interconnectedly installed at the bottom of the water distribution plate 51 spray the water source in the water distribution plate 51 onto the ore raw materials on the conveying platform 1 in the form of spraying, forming a fine water mist, thereby achieving spray dust reduction on the ore raw materials and effectively reducing the dust generated during the ore transportation process; Finally, when the device needs to be maintained, stored or drained in other situations, open the pipe cover at the mouth of the drain pipe 34. Since there is a certain water pressure in the filling cylinder 31 and the drain pipe 34 is interconnected at both ends of the filling cylinder 31, the water in the filling cylinder 31 is discharged from the device through the drain pipe 34 under the action of its own gravity and residual water pressure, completing the drainage operation.
