Description

Technical Field

[0001] This invention belongs to the field of sand and gravel conveying technology, specifically a sand and gravel belt conveyor device. Background Technology

[0002] Sand and gravel refers to a loose mixture of sand and gravel. Due to its good hardness and stable chemical properties, sand and gravel are often used as high-quality building materials. Generally, sand and gravel are transported using belt conveyors during processing.

[0003] Belt conveyors, also known as belt conveyors, are generally driven by drive rollers and idler rollers, which in turn drive the belt to transport materials. They rely on the principle of friction transmission to move the belt and are suitable for conveying powdery, granular, and small lump materials.

[0004] When using a belt conveyor to transport sand and gravel, since most of the sand and gravel are piled up in the open, they will get damp due to rain. During the transportation process, some of the sand and gravel will easily stick to the idler rollers of the belt conveyor, causing the idler rollers to become uneven, which will make the belt prone to deviation.

[0005] Therefore, the present invention provides a sand and gravel conveyor belt device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a sand and gravel conveyor belt, including a base; a fixed frame is symmetrically fixed to the top of the base in pairs, and multiple fixed frames are provided; a fixed rod is fixedly fixed to the outside of the multiple fixed frames, and a fixed rod is fixed between two symmetrical fixed frames; a first idler roller is rotatably connected to the middle of the fixed rod; a second idler roller is rotatably connected to the outside of both sides of the fixed rod; a conveyor belt is installed on the first and second idlers, and the two ends of the conveyor belt are assembled through a drive roller and a redirecting roller; a support plate is fixedly fixed to the outside of the fixed frame; a scraper is fixedly fixed to the outside of the support plate, and the scraper is in contact with the outside of the first and second idlers; reducing the adhesion of sand and gravel on the surface of the first and second idlers, and reducing the occurrence of belt deviation due to unevenness of the surface of the first and second idlers.

[0008] Preferably, a collection plate is fixedly connected to the outside of the fixed frame, and the collection plate is located above the machine base; a filter screen is fixedly connected to the outside of the collection plate; this serves to collect materials, and the filter screen can filter out large particles of sand and gravel, thus separating and collecting sand and gravel of different sizes.

[0009] Preferably, a water tank is fixedly connected to the top of the collecting plate; a water pump is installed inside the water tank; a conveying pipe is fixedly connected to the output end of the water pump, and one end of the conveying pipe is connected to the inside of the support plate; a solenoid valve is installed on the conveying pipe; multiple sets of nozzles are fixedly connected to the outside of the support plate, and the multiple sets of nozzles are connected to the conveying pipe through the support plate; this has the effect of rinsing the scraper area, thereby reducing the adhesion of sand and gravel on the surface of the first and second idlers, and the rinsed water will fall to the collecting plate for collection, which is convenient for subsequent recycling. At the same time, rinsing the scraper area can have a cleaning effect, reducing the material adhesion on the scraper and maintaining the scraping effect of the scraper.

[0010] Preferably, a sensor is installed inside the second idler roller, and the sensor is electrically connected to the water pump; a squeezing rod is slidably connected inside the second idler roller; an elastic element is fixed to the bottom end of the squeezing rod, and the elastic element is located above the sensor; this reminds the workers that the conveyor belt is misaligned and needs to be corrected, and at the same time the sensor will also send a signal to the water pump to pump water to wash the surfaces of the first and second idler rollers, thereby controlling and washing away any attached substances.

[0011] Preferably, the second idler roller has an oil storage chamber and a flow groove inside; a second solenoid valve is installed inside the second idler roller, and the second solenoid valve is located between the oil storage chamber and the flow groove; the second solenoid valve is electrically connected to the sensor; it serves to lubricate the inner wall of the second idler roller, reducing the possibility of the second idler roller being difficult to rotate due to jamming, thereby affecting the normal conveying of the conveyor belt and causing deviation.

[0012] Preferably, a first sealing ring and a second sealing ring are fixedly connected inside the second idler roller; both the first sealing ring and the second sealing ring are made of rubber; they serve to seal the lubricating oil, and as the second idler roller rotates, more lubricating oil can be applied to the surface of the fixed rod and the second idler roller, improving the lubrication effect on the inner wall of the second idler roller.

[0013] Preferably, multiple sets of sponge blocks are fixedly connected inside the second idler roller, and the multiple sets of sponge blocks are located at the flow groove; brushes are fixedly connected to the outside of the multiple sets of sponge blocks; after the multiple sets of sponge blocks are saturated, a small amount of lubricating oil will overflow, but most of the lubricating oil will be sealed at the multiple sets of sponge blocks, thereby sealing the lubricating oil and improving the lubricating oil coating effect.

[0014] Preferably, a support frame is fixedly connected to the top of the fixed frame at the front end of the sand and gravel conveyor belt; a rotating shaft is rotatably connected to the middle of the support frame via a torsion spring; a pressure plate is fixedly connected to the outside of the rotating shaft; when excessive sand and gravel passes through the pressure plate, the pressure plate can guide and spread the sand and gravel, thereby reducing the situation of excessive accumulation of sand and gravel on one side.

[0015] Preferably, a guide block is fixed to the side of the support frame away from the pressure plate; the cross-sectional shape of the guide block is triangular; it spreads the sand and gravel to both sides, thereby diverting the accumulated sand and gravel.

[0016] Preferably, a collection pool is provided on the outside of the collection plate; a water pump is fixedly connected to the outside of the water pump, and one end of the water pump is located at the collection pool; a filter element is installed at the end of the water pump near the collection pool; the collection pool is used to store the collected water, which is convenient for the water pump to draw water from. At the same time, the filter screen can filter out large particles of sand and gravel, and the filter element at the end of the water pump can filter out fine sand and gravel, thereby reducing the possibility of blockage when the water pump draws water.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The sand and gravel conveyor belt device of the present invention uses scrapers attached to the surfaces of the first and second idlers. As the first and second idlers rotate, the scrapers are scraped, thereby reducing the adhesion of sand and gravel to the surfaces of the first and second idlers and reducing belt deviation. The scraped sand and gravel is collected by a collection plate and separated by a filter screen. Multiple sets of nozzles spray the scraper area to maintain the scraping effect. When the belt deviates, a sensor is triggered to alert the workers and control the pumping of water to spray the scraper area. The lubricating oil overflowing from the flow channel moistens the inner wall of the second idler, which lubricates the fixing rod and the second idler.

[0019] 2. The sand and gravel conveyor belt device of the present invention reduces the overflow of lubricating oil and improves the lubrication effect on the surface of the fixed rod by setting a first sealing ring and a second sealing ring to adhere to the surface of the fixed rod. The lubricating oil is absorbed by a sponge block and applied to the fixed rod and the second idler roller by multiple sets of brushes to improve the application effect of the lubricating oil. The material accumulated in the middle of the conveyor belt is diverted by the guide block and the material is spread out by the pressure plate, which reduces the situation of the conveyor belt running off-center due to excessive material on one side.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1

[0032] like Figures 1 to 4 , Figure 6 , Figure 7As shown in the embodiment of the present invention, a sand and gravel conveyor belt includes a base 1; a plurality of fixing frames 11 are symmetrically fixed to the top of the base 1; fixing rods 12 are fixed to the outside of the plurality of fixing frames 11, and a fixing rod 12 is fixed between two symmetrical fixing frames 11; a first idler roller 13 is rotatably connected to the middle of the fixing rod 12; second idler rollers 14 are rotatably connected to the outside of both sides of the fixing rod 12; the first idler roller 13 and the second idler roller 14 are mounted on... A conveyor belt 15 is installed, and both ends of the conveyor belt 15 are assembled via drive rollers and redirecting rollers; a support plate 16 is fixedly connected to the outside of the fixed frame 11; a scraper 17 is fixedly connected to the outside of the support plate 16, and the scraper 17 is in contact with the outside of the first idler roller 13 and the second idler roller 14; when using a belt conveyor to transport sand and gravel, since most of the sand and gravel is piled up in the open air, the sand and gravel will become damp due to rain. During the transportation process, some sand and gravel easily adheres to the idler rollers of the belt conveyor, causing the idler roller surface to become uneven. This can easily lead to belt misalignment. Therefore, in this embodiment of the invention, when conveying sand and gravel, the base 1 serves as the main structure of the sand and gravel belt conveyor. Multiple fixing frames 11 are assembled on both sides of the top of the base 1. Fixing rods 12 are connected between two fixing frames 11, serving as support points for the first idler roller 13 and two second idler rollers 14. The belt 15 is mounted on the conveyor via drive rollers and redirecting rollers at both ends, and the belt 15 adheres to the first idler roller 13 and the second idler roller 14. On the surface, when the drive drum rotates, it drives the conveyor belt 15 to move to transport sand and gravel. The conveyor belt 15 drives multiple first rollers 13 and second rollers 14 to rotate synchronously. When some of the damp sand and gravel adheres to the first rollers 13 and second rollers 14, the scraper 17 on the support plate 16 will scrape against the surface of the first rollers 13 and second rollers 14, thereby reducing the adhesion of sand and gravel on the surface of the first rollers 13 and second rollers 14 and reducing the possibility of the conveyor belt 15 running off-center due to the uneven surface of the first rollers 13 and second rollers 14.

[0033] like Figures 1 to 3 As shown, a collection plate 2 is fixedly connected to the outside of the fixed frame 11, and the collection plate 2 is located above the machine base 1; a filter screen 21 is fixedly connected to the outside of the collection plate 2; after the sand and gravel adhering to the surface of the first roller 13 and the second roller 14 are scraped off, the collection plate 2 is fixed below the first roller 13 and the second roller 14 to collect the scraped sand and gravel, which achieves the effect of collecting materials, and the filter screen 21 can filter large particles of sand and gravel, which plays the role of separating and collecting sand and gravel of different sizes.

[0034] like Figures 1 to 4As shown, a water tank 3 is fixedly connected to the top of the collecting plate 2; a water pump is installed inside the water tank 3; a conveying pipe is fixedly connected to the output end of the water pump, and one end of the conveying pipe is connected to the inside of the support plate 16; a solenoid valve 31 is installed on the conveying pipe; multiple sets of nozzles 32 are fixedly connected to the outside of the support plate 16, and the multiple sets of nozzles 32 are connected to the conveying pipe through the support plate 16; when the sand and gravel adhere tightly to the first idler roller 13 and the second idler roller 14, the water pump inside the water tank 3 is used to pump out the water from inside the water tank 3. The stored water, after the first solenoid valve 31 is opened, is transported from the conveying pipe to the inside of the support plate 16, and sprayed onto the scraper 17 through multiple sets of nozzles 32, which has the effect of rinsing the scraper 17, thereby reducing the adhesion of sand and gravel on the surface of the first idler roller 13 and the second idler roller 14. The rinsed water will fall into the collection plate 2 for collection, which is convenient for subsequent recycling. At the same time, the rinsing of the scraper 17 can have a cleaning effect, reducing the material adhesion on the scraper 17 and maintaining the scraping effect of the scraper 17.

[0035] like Figures 1 to 3 , Figure 6 , Figure 7 As shown, a sensor 4 is installed inside the second idler roller 14, and the sensor 4 is electrically connected to the water pump; a squeezing rod 41 is slidably connected inside the second idler roller 14; an elastic element 42 is fixedly connected to the bottom end of the squeezing rod 41, and the elastic element 42 is located above the sensor 4; when the conveyor belt 15 deviates during transport, the conveyor belt 15 will press against the protruding arc-shaped surface of the squeezing rod 41, thereby causing the squeezing rod 41 to slide into the interior of the second idler roller 14. The squeezing rod 41 squeezes and contracts the elastic element 42, and the squeezing rod 41 also triggers the sensor 4. The sensor 4 then sends a signal to the operator to warn them that the conveyor belt 15 needs to be corrected due to deviation. At the same time, the sensor 4 also sends a signal to the water pump to pump water to wash the surfaces of the first idler roller 13 and the second idler roller 14, thereby controlling and washing away any adhering substances.

[0036] The second idler roller 14 has an oil storage chamber 5 and a flow channel 51 inside; a second solenoid valve 52 is installed inside the second idler roller 14, and the second solenoid valve 52 is located between the oil storage chamber 5 and the flow channel 51; the second solenoid valve 52 is electrically connected to the sensor 4; when the conveyor belt 15 is conveying sand and gravel, one side of the second idler roller 14 may become stuck, and the speed of the stuck second idler roller 14 will be lower than the speed of the normal second idler roller 14 on the other side, thus causing the conveyor belt 15 to become stuck on one side. When the second idler roller 14 deviates and the conveyor belt 15 runs off-track, the sensor 4 is triggered by the pressure of the conveyor belt 15. The sensor 4 sends a signal to the second solenoid valve 52 to open. Because the second idler roller 14 is installed at an angle, the lubricating oil inside the oil storage chamber 5 will flow from the second solenoid valve 52 to the flow groove 51, and overflow from multiple outlets of the flow groove 51 to the inner wall of the second idler roller 14, which will lubricate the inner wall of the second idler roller 14 and reduce the situation where the second idler roller 14 is difficult to rotate due to jamming, thus affecting the normal conveying of the conveyor belt 15 and causing it to run off-track.

[0037] The second idler roller 14 is internally fixed with a first sealing ring 6 and a second sealing ring 61. Both the first sealing ring 6 and the second sealing ring 61 are made of rubber. When the lubricating oil flows out from the flow groove 51, the first sealing ring 6 and the second sealing ring 61 are fixed to both ends of the second idler roller 14 respectively. The rubber material of the first sealing ring 6 and the second sealing ring 61 adheres to the surface of the fixing rod 12, which has the effect of sealing the lubricating oil. As the second idler roller 14 rotates, more lubricating oil can be applied to the surface of the fixing rod 12 and the second idler roller 14, improving the lubrication effect on the inner wall of the second idler roller 14.

[0038] Multiple sets of sponge blocks 7 are fixedly connected inside the second idler roller 14, and the multiple sets of sponge blocks 7 are located at the flow groove 51; brushes are fixedly connected to the outside of the multiple sets of sponge blocks 7; when the lubricating oil flows out from the oil storage chamber 5, the multiple sets of sponge blocks 7 absorb the lubricating oil. When the fixed rod 12 rotates, it will come into contact with the multiple sets of sponge blocks 7, so that the brushes on the multiple sets of sponge blocks 7 will apply the lubricating oil to the fixed rod 12 and the second idler roller 14. After the multiple sets of sponge blocks 7 are saturated, a small amount of lubricating oil will overflow, but most of the lubricating oil will be sealed at the multiple sets of sponge blocks 7, thereby sealing the lubricating oil and improving the effect of lubricating oil application.

[0039] like Figures 1 to 3 , Figure 5As shown, a support frame 8 is fixedly connected to the top of the fixed frame 11 at the front end of the sand and gravel conveyor belt; a rotating shaft 81 is rotatably connected to the middle of the support frame 8 via a torsion spring; a pressure plate 82 is fixedly connected to the outside of the rotating shaft 81; when a large amount of sand and gravel is fed onto the conveyor belt 15, excessive material may accumulate on one side of the conveyor belt 15 during feeding, causing the conveyor belt 15 to easily deviate. By using the pressure plate 82 in conjunction with the torsion spring on the rotating shaft 81, the pressure plate 82 is pressed and covered over the conveyor belt 15, leaving a gap between the conveyor belt 15 and the pressure plate 82. When excessive sand and gravel passes over the pressure plate 82, the pressure plate 82 can guide and spread the sand and gravel, thereby reducing the situation of excessive accumulation of sand and gravel on one side.

[0040] A guide block 9 is fixed to the side of the support frame 8 away from the pressure plate 82; the cross-sectional shape of the guide block 9 is triangular; when too much sand and gravel accumulates in the middle of the tape 15, the guide block 9 is fixed to the front end of the support frame 8, and after the sand and gravel reaches the guide block 9, it will be guided by the triangular side of the guide block 9, spreading the sand and gravel to both sides, thus diverting the accumulated sand and gravel.

[0041] Example 2

[0042] like Figure 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a collection pool 91 is provided on the outside of the collection plate 2; a water pump is fixedly connected to the outside of the water pump, and one end of the water pump 92 is located at the collection pool 91; a filter element is installed at the end of the water pump 92 near the collection pool 91; when multiple sets of nozzles 32 spray water to the scraper 17, the falling water will be collected by the collection plate 2, and the water pump will draw it into the water tank 3 for internal circulation through the water pump 92. The collection pool 91 is used to store the collected water, which is convenient for the water pump to draw. At the same time, the filter screen 21 can filter large particles of sand and gravel first, and the filter element at the end of the water pump 92 can filter fine sand and gravel, thereby reducing the blockage caused by the water pump 92 when drawing water.

[0043] During operation, when conveying sand and gravel, the base 1 serves as the main structure of the sand and gravel belt conveyor. Multiple fixed frames 11 are mounted on both sides of the top of the base 1. Fixed rods 12 connect between two fixed frames 11, serving as support points for the first idler roller 13 and two second idler rollers 14. The belt 15 is mounted on the conveyor via drive rollers and redirecting rollers at both ends, and the belt 15 adheres to the surfaces of the first idler roller 13 and the second idler roller 14. When the drive rollers rotate, they drive the belt 15 to move and convey the sand and gravel. The belt 15, in turn, drives multiple idler rollers... The first idler roller 13 and the second idler roller 14 rotate synchronously. When some damp sand and gravel adhere to the first idler roller 13 and the second idler roller 14, the scraper 17 on the support plate 16 will scrape against the surfaces of the first idler roller 13 and the second idler roller 14, thereby reducing the adhesion of sand and gravel to the surfaces of the first idler roller 13 and the second idler roller 14 and reducing the possibility of the conveyor belt 15 running off-center due to the uneven surfaces of the first idler roller 13 and the second idler roller 14. The collecting plate 2 is fixed below the first idler roller 13 and the second idler roller 14 to collect the scraped sand and gravel, thus achieving the effect of material collection. Furthermore, the filter screen 21 can filter large particles of sand and gravel, effectively separating and collecting sand and gravel of different sizes. The water pump inside the water tank 3 draws water from the tank, and after opening the first solenoid valve 31, water is transported through the delivery pipe to the inside of the support plate 16. Multiple nozzles 32 spray the water onto the scraper 17, effectively rinsing the scraped area and reducing the adhesion of sand and gravel to the surfaces of the first and second idler rollers 13 and 14. The rinsed water falls onto the collection plate 2 for collection and subsequent reuse. Meanwhile, the scraper... The 17 points being rinsed can achieve a cleaning effect, reduce the material adhesion on the scraper 17, and maintain the scraping effect of the scraper 17. When multiple sets of nozzles 32 spray water to the scraper 17, the falling water will be collected by the collection plate 2 and pumped by the water pump through the water pumping pipe 92 to the water tank 3 for internal circulation. The collection pool 91 is used to store the collected water for easy pumping. At the same time, the filter screen 21 can filter large particles of sand and gravel first, and the filter element at the end of the water pumping pipe 92 can filter fine sand and gravel, thereby reducing the possibility of blockage when the water pumping pipe 92 draws water.

[0044] When the conveyor belt 15 deviates from its designated path during transport, it presses against the protruding arc-shaped surface of the extrusion rod 41, causing the extrusion rod 41 to slide into the interior of the second idler roller 14. The extrusion rod 41 compresses the elastic element 42 and triggers the sensor 4, which then sends a signal to the operator to warn them that the conveyor belt 15 is deviating and needs correction. Simultaneously, the sensor 4 also sends a signal to the water pump to flush the surfaces of the first idler roller 13 and the second idler roller 14, thus controlling and washing away any adhering materials. Simultaneously, when the conveyor belt 15 is conveying sand and gravel, one side of the No. 2 idler roller 14 may become stuck. The speed of the stuck No. 2 idler roller 14 will be lower than the speed of the normal No. 2 idler roller 14 on the other side, causing the conveyor belt 15 to deviate towards the stuck No. 2 idler roller 14. When the conveyor belt 15 deviates, the sensor 4 is triggered by the pressure of the conveyor belt 15. The sensor 4 sends a signal to the No. 2 solenoid valve 52 to open. Because the No. 2 idler roller 14 is installed at an angle, the lubricating oil inside the oil storage chamber 5 will flow from the No. 2 solenoid valve 52 to the flow... At channel 51, lubricating oil overflows from multiple outlets at channel 51 onto the inner wall of the second idler roller 14, thus reducing the risk of the second idler roller 14 becoming stuck and unable to rotate, which could affect the normal conveying of the conveyor belt 15 and cause deviation. Sealing rings 6 and 61 are fixed to both ends of the second idler roller 14, respectively. The rubber material of sealing rings 6 and 61 adheres to the surface of the fixing rod 12, effectively sealing the lubricating oil. As the second idler roller 14 rotates, the lubricating oil can... This allows more lubricating oil to be applied to the surfaces of the fixed rod 12 and the second idler roller 14, improving the lubrication effect on the inner wall of the second idler roller 14. Multiple sets of sponge blocks 7 are used to absorb the lubricating oil. When the fixed rod 12 rotates, it will come into contact with the multiple sets of sponge blocks 7, and the brushes on the multiple sets of sponge blocks 7 will apply the lubricating oil to the fixed rod 12 and the second idler roller 14. After the multiple sets of sponge blocks 7 are saturated, a small amount of lubricating oil will overflow, but most of the lubricating oil will be sealed at the multiple sets of sponge blocks 7, thereby sealing the lubricating oil and improving the lubricating oil application effect.

[0045] When a large amount of sand and gravel is fed onto the conveyor belt 15, excessive material may accumulate on one side of the belt, causing it to easily deviate from its designated path. The pressure plate 82, in conjunction with the torsion spring on the rotating shaft 81, covers and presses down on the conveyor belt 15, leaving a gap between the belt 15 and the pressure plate 82. When excessive sand and gravel passes over the pressure plate 82, the pressure plate 82 guides and spreads the sand and gravel, reducing excessive accumulation on one side. The guide block 9, fixed to the front end of the support frame 8, guides the sand and gravel to both sides after it reaches the guide block 9, thus diverting the accumulated sand and gravel.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
