Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying and spraying technology, and more specifically, to a mobile crusher material conveying and spraying device. Background Technology
[0002] Mobile crushers are widely used in agriculture, mining, construction and other fields for on-site material crushing and processing. Existing mobile crushers typically consist of a power system, crushing device, conveyor belt and frame. During operation, materials enter the crushing device, are crushed, and then transported by the conveyor belt to a designated location for stockpiling.
[0003] However, in actual operations, the crushed materials often require humidification, chemical spraying, or dust removal to meet subsequent processing, transportation, or environmental protection requirements. Existing technologies often employ the following methods for spray humidification or chemical spraying: secondary treatment is performed manually or with independent spraying equipment after material stockpiling, which not only increases operational steps and labor costs but also results in uneven spraying and low efficiency; some equipment installs the spraying device inside the crusher or at the discharge port, but due to the limited space within the crushing chamber and the high-speed movement of the material, the spraying effect is poor, the equipment is prone to clogging, and maintenance is difficult; fixed pipelines are used to arrange the spraying device above the conveyor belt, but the pipelines and nozzles lack effective protective structures, making them susceptible to external wind forces causing spraying direction deviation, and they cannot adapt to the frequent movement requirements of mobile equipment.
[0004] Furthermore, existing spraying systems lack effective linkage control with the crusher, failing to automatically adjust the spray flow rate based on material throughput, resulting in waste of water or chemicals. Simultaneously, in high-dust working environments, the unprotected spraying devices are susceptible to dust contamination, affecting spraying effectiveness and equipment lifespan. Therefore, there is an urgent need for a spraying system that can be integrated with a mobile crusher, simultaneously completing spraying operations during material transport, possessing a stable structure, and providing excellent spraying results, to address the aforementioned problems in existing technologies. Utility Model Content
[0005] In view of this, this utility model addresses the shortcomings of the existing technology by proposing a mobile crusher for materials. The conveying spray equipment aims to solve the problems of existing mobile crushers in material processing, such as the need for secondary spraying, uneven spraying due to external interference, weak adaptability to mobile operations, and frequent maintenance and short lifespan due to corrosion and blockage.
[0006] This utility model provides a mobile crusher material conveying and spraying device, including: crusher body, protective cover, spray head, explosion-proof water pipe, fixing plate, pressure pump, water tank and conveyor belt; The protective cover is fixedly welded to the support frame on both sides of the conveyor belt and is used to install the nozzle and the fixing plate; The nozzle is fixed based on the fixing plate and is used to spray materials with an adjustable spray flow rate. The explosion-proof water pipe is connected to the nozzle with a threaded end and to the pressurization pump with a threaded end for the transmission of spray fluid. The fixing plate is connected to the inner wall of the protective cover by bolts, and is used to reinforce the protective cover; The pressure pump and the water tank are both located on the outer side of the main body of the crusher. The water outlet of the water tank is connected to the water inlet of the pressure pump, and the material outlet of the crusher is connected to the material inlet of the conveyor belt. This allows the crushed material to be directly transported to the conveyor belt below the protective cover and sprayed synchronously by the nozzles. The conveyor belt is connected to the main body of the crusher by bolts and is used to transport the crushed material.
[0007] Furthermore, the end of the protective cover away from the main body of the crusher is provided with an outwardly inclined guide side, the angle between the guide side and the conveyor belt is 120-150°, which is used to guide the material to be output smoothly after spraying.
[0008] Furthermore, the explosion-proof water pipe is provided with a first explosion-proof water pipe, a second explosion-proof water pipe, and a third explosion-proof water pipe connected in series to form a conveying channel from the outlet of the booster pump to the nozzle; a fourth explosion-proof water pipe is also provided, one end of which is connected to the inlet of the booster pump by a thread, and the other end extends into the water tank to independently complete the fluid supply from the water tank to the booster pump.
[0009] Furthermore, one end of the first explosion-proof water pipe is connected to the water inlet of the nozzle via a thread, and the other end is connected to one end of the second explosion-proof water pipe via a quick connector with a sealing gasket. The other end of the second explosion-proof water pipe extends along the conveyor belt support bracket and is connected to one end of the third explosion-proof water pipe via the quick connector. The other end of the third explosion-proof water pipe is welded to the water outlet of the pressure pump.
[0010] Furthermore, the explosion-proof water pipe is provided with an insulation layer, which is located on the outer surface of the explosion-proof water pipe to prevent the fluid inside the pipe from freezing in low-temperature environments.
[0011] Furthermore, an L-shaped mounting bracket is provided on the outer side of the main body of the crusher, and the pressure pump and the water tank are connected to the L-shaped mounting bracket by bolts.
[0012] Furthermore, a reinforcing rib extending along its length is provided in the middle of the fixing plate, and the reinforcing rib is integrally formed with the fixing plate.
[0013] Furthermore, the protective cover is provided with a high-temperature resistant and corrosion-resistant coating, which is disposed on the inner side of the protective cover to prevent the spray fluid and material residue from corroding the protective cover.
[0014] Furthermore, the support frames on both sides of the conveyor belt are provided with positioning bosses that are adapted to the welding position of the protective cover, and the positioning bosses are integrally formed with the support frames.
[0015] Furthermore, the inlet end of the nozzle is provided with a flow regulating valve core, which is controlled by an adjusting knob. A sealing sleeve is provided between the adjusting knob and the protective cover to maintain the sealing of the protective cover when adjusting the flow rate.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: By integrating and modularizing components such as the protective cover, nozzles, explosion-proof water pipes, pressurized pumps, and water tanks with the conveyor belt and crusher body, an integrated "crushing-conveying-spraying" operation is achieved, effectively solving the problems of cumbersome procedures and low efficiency in existing technologies that require secondary spraying after material stacking. Specifically, the protective cover is fixedly welded to the support frames on both sides of the conveyor belt, forming a relatively enclosed space. Combined with the fixing plates bolted to its inner wall, this not only provides a stable installation foundation for the nozzles, ensuring uniform distribution along the width of the conveyor belt for precise and uniform spraying of materials, but also effectively blocks external wind interference, improving the spraying effect. Simultaneously, the reinforcing ribs in the middle of the fixing plates and the positioning bosses on the conveyor belt support frames further enhance the stability and installation accuracy of the overall equipment structure. The multi-section explosion-proof water pipe design, especially the combination of quick couplings and threaded connections, allows for flexible pipe layout, adapting to the space requirements and transfer characteristics of mobile equipment, and its outer insulation layer prevents the fluid inside the pipe from freezing in low-temperature environments. The L-shaped mounting bracket on the outer side of the crusher body provides a compact and stable mounting platform for the pressure pump and water tank, integrating the power and supply units. The 120-150° guide edge of the protective cover away from the crusher guides the sprayed material smoothly out, preventing jamming and accumulation at the end of the conveyor. The high-temperature resistant and corrosion-resistant coating on the inner side of the protective cover and the external adjustment knob with a sealing sleeve at the nozzle inlet not only reduce the difficulty of equipment maintenance and extend its service life, but also maintain the sealing of the cover's interior when adjusting the flow rate, reducing dust leakage. In summary, this utility model has a compact structure, reasonable layout, convenient installation and maintenance, and strong adaptability. It can significantly improve operating efficiency and material processing quality, while also being energy-saving and safe, possessing outstanding practical value and promising prospects for promotion.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0022] Please see Figure 1-5 In some embodiments of this application, this embodiment provides a mobile crusher material conveying spraying device, including: crusher body 100, protective cover 300, spray head 110, explosion-proof water pipe 120, spray head 110 fixing plate, pressure pump 180, water tank 190 and conveyor belt 310.
[0023] In this technical solution, the protective cover 300 is fixedly welded to the support frame 320 on both sides of the conveyor belt 310, and is used to install the nozzle 110 and the nozzle 110 fixing plate; The nozzle 110 is fixed based on the nozzle 110 fixing plate and is used to spray materials with an adjustable spray flow rate. The explosion-proof water pipe 120 is sealed to the nozzle 110 at one end based on a thread, and sealed to the pressure pump 180 at the other end, for the transmission of spray fluid; The nozzle 110 fixing plate is connected to the inner wall of the protective cover 300 by bolts, and is used to reinforce the protective cover 300; The pressure pump 180 and the water tank 190 are both located on the outer side of the main body of the crusher. The water outlet of the water tank 190 is connected to the water inlet of the pressure pump 180. The discharge end of the crusher is connected to the feed end of the conveyor belt 310, so that the crushed material can be directly transported to the conveyor belt 310 below the protective cover 300 and sprayed synchronously by the nozzle 110. The conveyor belt 310 is connected to the crusher body 100 by bolts and is used to transport the crushed material.
[0024] In a preferred embodiment, such as Figure 4 As shown, the protective cover 300 is provided with an outwardly inclined guide edge 400 at one end away from the main body 100 of the crusher. The angle between the guide edge 400 and the conveyor belt 310 is 120-150°, which is used to guide the material to be output smoothly after spraying.
[0025] It is understood that the guide edge 400 is a plate-like structure extending outward from the end of the protective cover 300. It is integrally formed with the main body of the protective cover 300 or fixed by welding, and the edges are rounded to avoid scratching materials and operators. The angle between the guide edge 400 and the conveying plane of the conveyor belt 310 is set to 120-150°. This angle range is optimized and determined based on full consideration of the material's angle of repose, the running speed of the conveyor belt 310, and the change in material humidity after spraying. Material conveying tests have verified that when the material particle size is ≤5mm and the conveyor belt speed is 0.8-1.2m / s, a 130° inclination angle can reduce the accumulation rate to <5%, a 140° inclination angle is suitable for materials with humidity >15%, and a 120° inclination angle is suitable for high-flow spraying conditions. It can provide sufficient guiding space for materials with different particle sizes and humidity, and effectively avoid material retention caused by too small an angle or a decrease in protective performance caused by too large an angle. The guide edge 400 firstly receives and guides the sprayed material through its smooth, inclined surface, eliminating the obstruction effect of the traditional vertical shield 300 edge on the material. This significantly reduces the risk of jamming, accumulation, and overload of the conveyor belt 310 at the end of the conveyor, ensuring the continuity and stability of the entire "crushing-spraying-conveying" process. Secondly, the outward-inclined structure forms a controllable airflow outlet without compromising the windproof and airtight seal of the shield 300. This helps balance the air pressure inside and outside the shield 300, promptly expelling water vapor and dust generated by spraying, reducing corrosion and clogging of the nozzle 110 and the inner wall of the shield 300, extending the equipment's service life, and reducing maintenance frequency. Simultaneously, this design broadens the operator's field of vision for observing the material status at the end of the conveyor, facilitating real-time monitoring of the spraying effect and flow rate adjustment. Furthermore, the inclined edge and rounded corners enhance operational safety, avoiding the scratching hazards caused by sharp structures. In addition, for mobile operation scenarios, the smooth contour of the guide edge 400 reduces the probability of collisions with external obstacles during equipment relocation, improving the overall structural spatial adaptability.
[0026] In a preferred embodiment, such as Figure 3 As shown, the explosion-proof water pipe 120 is provided with a first explosion-proof water pipe 130, a second explosion-proof water pipe 140, and a third explosion-proof water pipe 150 connected in series to form a conveying channel from the water outlet of the booster pump 180 to the nozzle 110; a fourth explosion-proof water pipe 240 is also provided, one end of which is connected to the water inlet of the booster pump 120 by a thread, and the other end extends into the water tank 190 to independently complete the fluid supply from the water tank 190 to the booster pump 120.
[0027] In a preferred embodiment, one end of the first explosion-proof water pipe 130 is connected to the water inlet of the nozzle 110 via a thread, and the other end is connected to one end of the second explosion-proof water pipe 140 via a quick connector with a sealing gasket. The other end of the second explosion-proof water pipe 140 extends along the support bracket of the conveyor belt 310 and is connected to one end of the third explosion-proof water pipe 150 via the quick connector. The other end of the third explosion-proof water pipe 150 is welded to the water outlet of the pressure pump 120.
[0028] In a preferred embodiment, such as Figure 4 As shown, the explosion-proof water pipe 120 is provided with a heat insulation layer 210, which is disposed on the outer side of the explosion-proof water pipe 120 to prevent the fluid inside the pipe from freezing in low-temperature environments.
[0029] It is understood that in this embodiment, the explosion-proof water pipe 120 is subdivided into four independent units: one end of the fourth explosion-proof water pipe 240 is sealed to the water inlet of the booster pump 180 by a thread, and the other end extends into the water tank 190 to form an independent fluid supply branch; the water outlet of the booster pump 180 is welded to the third explosion-proof water pipe 150, which is connected in sequence to the second explosion-proof water pipe 140 extending along the conveyor belt support bracket and the first explosion-proof water pipe 130 directly connected to the water inlet of the nozzle by a quick connector with a sealing gasket. The outer surfaces of the four explosion-proof water pipes 120 are all wrapped with an insulation layer 210, forming a complete, segmented, sealed fluid transport system with insulation function from the water tank 190 to the nozzle 110. The four-section design separates the supply and delivery functions, facilitating independent maintenance and replacement. Quick couplings, combined with sealing gaskets, enable rapid disassembly and reliable sealing of pipelines. Welded connections ensure the structural strength and leak-proof performance of critical high-pressure components. The layout extending along the support optimizes equipment space, reduces pipeline clutter and interference, and is suitable for mobile operation scenarios. The 210mm insulation layer fully covers the entire area, effectively preventing the fluid inside the pipes from freezing in low-temperature environments, ensuring the stability of equipment startup and continuous operation under severe cold conditions, while reducing energy consumption and maintenance frequency.
[0030] In a preferred embodiment, such as Figure 1 As shown, an L-shaped mounting bracket 200 is provided on the outer side of the main body 100 of the crusher, and the pressure pump 180 and the water tank 190 are connected to the L-shaped mounting bracket 200 by bolts.
[0031] Understandably, the L-shaped mounting bracket 200 is made of 3-5mm thick galvanized steel plate. Its vertical section is firmly connected to the outer side of the crusher body 100 by welding or bolts, and its horizontal section extends towards the conveyor belt 310. The pressure pump 180 is fixed to the horizontal section with bolts with anti-slip washers (to meet load-bearing requirements), and the water tank 190 is fixed to the vertical section with bolts of the same specification (to make efficient use of vertical space). The L-shaped structure can make full use of the three-dimensional space on the side of the crusher, without occupying the working area of the conveyor belt 310, making the equipment layout more compact. The bolt connection facilitates the disassembly and maintenance of the pressure pump 180 and the water tank 190. The anti-slip washers and thickened steel plate can resist operating vibration and prevent component displacement, adapting to the relocation and dynamic operation requirements of mobile crushers.
[0032] In a preferred embodiment, such as Figure 1 As shown, a reinforcing rib 160 extending along its length is provided in the middle of the nozzle 110 fixing plate, and the reinforcing rib 160 is integrally formed with the nozzle 110 fixing plate.
[0033] It is understood that the nozzle 110 fixing plate is made of 3-5mm thick stainless steel plate, with a V-shaped (or U-shaped) reinforcing rib 160 integrally formed along its length. The reinforcing rib 160 has a height of 3-5mm and a thickness consistent with the fixing plate (2-3mm), and runs through the entire length of the nozzle 110 fixing plate, forming an integrated "plate-rib" load-bearing structure. Simultaneously, the two sides of the reinforcing rib 160 smoothly transition to the surface of the fixing plate, preventing the accumulation of dust or material residue. The integrally formed reinforcing rib 160 requires no additional welding or splicing, thus eliminating... In addition to reducing the risk of cracking due to stress concentration at welding points, the fixed plate also significantly improves its resistance to bending and vibration. It can effectively resist the vibration and impact of the conveyor belt 310 during operation and the downward force generated by the nozzle 110 and fluid pressure, preventing the fixed plate from deforming and shifting. This ensures that the nozzle 110 always maintains a precise spray angle and position, guaranteeing spray uniformity. Furthermore, the presence of the reinforcing rib 160 allows for a suitable reduction in the thickness of the fixed plate while ensuring structural strength, reducing material usage and overall weight. The smooth transition structure facilitates cleaning and maintenance, extending the service life of the components.
[0034] In a preferred embodiment, such as Figure 3 As shown, the protective cover 300 is provided with a high-temperature resistant and corrosion-resistant coating 500, which is disposed on the inner side of the protective cover 300 to prevent the spray fluid and material residue from corroding the protective cover 300.
[0035] It is understood that the high-temperature resistant and corrosion-resistant coating 500 on the inner side of the protective cover 300 is a ceramic-based composite coating or a polytetrafluoroethylene modified coating. It is uniformly applied to the inner wall of the protective cover 300 using an electrostatic spraying process, with the coating thickness controlled at 0.1-0.2 mm. After spraying, it undergoes a curing treatment at 120-150℃ to ensure a tight bond between the coating and the metal substrate (stainless steel) of the protective cover 300, eliminating the risk of peeling. Simultaneously, the coating surface maintains a certain smoothness to reduce material residue adhesion. This coating can withstand the potential corrosion during the crushing operation. The instantaneous high temperature of 60-120℃ avoids the scorching damage to the inner wall of the protective cover 300 caused by hot materials. At the same time, it can resist the chemical erosion of spray water and insect / corrosion agents, prevent the inner wall of the protective cover 300 from rusting or being corroded and perforated, and extend the service life of the protective cover 300. In addition, the smooth coating surface makes it easy to clean residual material debris, reduce the pollution of the inner wall of the protective cover 300 caused by residue accumulation, indirectly ensure the cleanliness of the environment around the nozzle 110, prevent the nozzle 110 from being blocked by impurities, and further maintain the stability of the spraying operation.
[0036] In a preferred embodiment, such as Figure 4 As shown, the support frames 320 on both sides of the conveyor belt 310 are provided with positioning bosses 330 that are adapted to the welding position of the protective cover 300. The positioning bosses 330 are integrally formed with the support frames 320.
[0037] It is understood that the positioning boss 330 is a rectangular or trapezoidal protrusion integrally formed with the support frames 320 on both sides of the conveyor belt 310. Its height is slightly higher than the top surface of the support frame 320, its width matches the bottom welding edge of the cover 300, and it is evenly distributed along the length of the support frame 320, providing a precise assembly reference and support surface for welding the cover 300. During welding, the bottom edge of the cover 300 is placed on the positioning boss 330 and aligned with it to achieve rapid positioning and stable support, ensuring consistent welding gaps and continuous and uniform welds. Firstly, it significantly improves the assembly accuracy and coaxiality of the protective cover 300 and the conveyor belt 310, effectively avoiding the skewness of the protective cover 300 caused by manual alignment errors, thus ensuring that the spray path of the nozzle 110 is always perpendicular to the material conveying direction, ensuring uniform spraying. Secondly, the one-piece molded positioning boss 330 enhances the local structural strength at the weld between the support frame 320 and the protective cover 300, forming a "point-line-surface" combined load-bearing system, which can better resist vibration and impact during equipment operation, prevent cracking of the welded parts, and extend the service life of the equipment. At the same time, the positioning boss 330 simplifies the production process, reduces the reliance on complex tooling fixtures, reduces the difficulty and labor intensity of welding operations, and improves production efficiency and yield. In addition, the neat welding datum can also reduce welding deformation and subsequent grinding and finishing work, improving the appearance quality of the equipment.
[0038] In a preferred embodiment, such as Figure 4As shown, the inlet end of the nozzle 110 is provided with a flow regulating valve core 220, which is controlled by an adjusting knob 230. A sealing sleeve is provided between the adjusting knob 230 and the protective cover 300 to maintain the sealing of the protective cover 300 when adjusting the flow.
[0039] It is understood that the flow regulating valve core 220 adopts a needle-type structure. One end of its valve stem is coaxially fixed with the regulating knob 230. The outer surface of the knob is provided with anti-slip texture for easy gripping and operation. The other end is rigidly connected to the valve core body. During adjustment, rotating the knob clockwise moves the valve core downward to narrow the water inlet channel, and rotating it counterclockwise moves the valve core upward to widen the channel, which can achieve precise control of the spray flow rate of 0.5-5L / min. The sealing sleeve is made of oil-resistant and aging-resistant nitrile rubber and is fitted in a stepped manner between the valve stem and the through hole of the cover 300. One end is tightly attached to the inner wall of the cover 300, and the other end is in contact with the inner side of the regulating knob 230, forming a double sealing structure. The adjusting knob 230 extends into the interior based on the mounting hole on the cover 300. Its end is provided with an external thread, which meshes with the internal threaded sleeve on the top of the flow regulating valve core 220 to form a threaded transmission mechanism. When the knob is rotated, the valve core moves up and down along the axis to adjust the channel opening. The needle valve core, combined with the visual adjustment of the knob, can flexibly adapt the flow rate according to the material processing volume and humidity requirements, avoiding waste of water resources or chemicals. The stepped nitrile rubber sealing sleeve can effectively prevent dust from overflowing from the cover 300 and external impurities from entering. It not only maintains the sealing of the cover 300 to maintain a stable spraying environment, but also prevents the valve core from being stuck by dust, extending the service life of the valve assembly. At the same time, the external adjustment design can be operated without disassembling the cover 300, greatly improving the convenience of maintenance.
[0040] In a specific embodiment of this application, the above steps are implemented in the following ways: In the operation of a mobile crusher, after the equipment is started, the crusher body 100 first crushes the material. The crushed material then directly enters the conveyor belt 310, which is bolted to the main body, and is conveyed by the conveyor belt 310 towards the protective cover 300. The protective cover 300 is precisely welded and fixed by the positioning boss 330 on the support frame 320 of the conveyor belt 310. The high-temperature resistant and corrosion-resistant coating 500 on its inner wall can resist the corrosion of the sprayed fluid and material residue. The nozzle 110 is securely installed in the middle by a nozzle 110 fixing plate with reinforcing ribs 160. The pressure pump 180 and the water tank 190 are fixed to the outside of the crusher body 100 by an L-shaped mounting bracket 200. The water tank 190 supplies water to the crusher. After being pressurized by the booster pump 180, the water is transported to the inlet end of the nozzle 110 through four explosion-proof water pipes 120 with insulation layers 210. The operator can control the needle-type flow regulating valve core 220 at the inlet end of the nozzle 110 through the adjusting knob 230 with a sealing sleeve on the outside of the protective cover 300 to precisely adjust the spray flow rate of 0.5-5L / min according to the material requirements, so as to achieve synchronous spraying during material transportation. After spraying, the material is smoothly discharged through the 120-150° guide edge 400 at the end of the protective cover 300. No secondary treatment is required throughout the process, which is suitable for the continuous and efficient needs of mobile operations. At the same time, the various sealing and protective structures ensure the stable operation of the equipment in dusty and low-temperature environments.
[0041] The working principle of each embodiment above is as follows: After the equipment is started, the raw material is first crushed by the crusher body 100. The crushed material falls directly onto the conveyor surface of the conveyor belt 310 through the connection structure between the crusher discharge end and the conveyor belt inlet end. The conveyor belt 310 then rotates, stably conveying the material to the spray area covered by the protective cover 300. At the same time, the water tank 190 fixed on the L-shaped mounting bracket 200 on the outside of the crusher body 100 delivers the fluid to be sprayed to the pressure pump 180. After the pressure pump 180 is started, it pressurizes the fluid. The pressurized fluid is stably conveyed to the nozzle 110 through the closed channel formed by the four-section explosion-proof water pipe 120. Operators can precisely control the spray flow rate of 0.5-5 L / min by adjusting the knob 230 with a sealing sleeve on the outside of the protective cover 300 and controlling the needle-type flow regulating valve core 220 at the water inlet of the nozzle 110, according to the material's moisture requirements. This ensures that the material conveyed downwards by the nozzle 110 is sprayed evenly. The high-temperature resistant and corrosion-resistant coating 500 on the inner wall of the protective cover 300 prevents the spray fluid and material residues from corroding the protective cover 300, and its closed structure also blocks external wind from interfering with the spray path. Finally, the sprayed material is continuously conveyed by the conveyor belt 310 and smoothly discharged through the 120-150° guide edge 400 at the end of the protective cover 300, realizing integrated continuous operation of "crushing-conveying-spraying".
