Description

Technical Field

[0001] The invention belongs to the technical field of asphalt conveying, in particular to an asphalt raw material conveying belt and a leakage-proof component used for the conveying belt. Background Art

[0002] Asphalt raw material conveyor belt is one of the important conveying equipment in asphalt mixing plant. Its main function is to transport asphalt raw material from one place to another. According to the material properties and conveying methods, conveyor belts are divided into rubber conveyor belts, wire rope core conveyor belts, cotton cloth core conveyor belts and other types. Asphalt raw material conveyor belts usually choose wear-resistant, high temperature resistant, oil-resistant and corrosion-resistant materials to adapt to the characteristics of asphalt raw materials and the conveying environment; among them, the leak-proof component of the asphalt raw material conveyor belt is crucial to ensure the smooth progress of the conveying process and reduce material waste. Its main function is to prevent material leakage from both sides of the belt.

[0003] Chinese invention patent CN116750443B relates to the technical field of cargo transportation, and specifically to an asphalt preparation conveying aggregate belt machine, comprising a base, two conveying rollers are arranged above the base, the two conveying rollers are connected by a conveying belt, first side plates are respectively arranged on both sides of the conveying belt, the two ends of the conveying rollers are respectively fixedly connected with a first rotating shaft, the first rotating shaft and the first side plate are connected by a bearing, and a first motor is fixedly connected to one of the first side plates; the asphalt raw material conveying belt has low conveying efficiency and poor conveying effect.

[0004] Chinese invention patent CN118125067B provides a modified asphalt production material conveying device, which relates to the field of asphalt production. The modified asphalt production material conveying device comprises: a guide rail and a transport box; the guide rail is slidably connected to a slide seat, and the slide seat is equipped with a driving member for driving the slide seat to slide along the guide rail; the transport box is arranged at the lower part of the slide seat, and an adjustment frame is connected between the transport box and the slide seat; the asphalt raw material conveying device has low operation difficulty and low conveying accuracy.

[0005] After the asphalt raw material is mixed, it needs to be transported. However, due to the different feeding rates and amounts of the asphalt raw material, it is easy to cause the asphalt raw material to be unevenly distributed above the conveyor belt, which in turn causes the conveyor belt to bend and deform, and ultimately affects the normal transmission efficiency of the asphalt raw material.

[0006] And when the asphalt raw materials accumulate on one side of the conveyor belt, the conveyor belt will tilt to one side accordingly, and eventually cause the asphalt raw materials to leak sideways.

[0007] At the same time, when the asphalt raw materials above the conveyor belt are transported to the end and unloaded, unloading by relying solely on the asphalt raw materials' own gravity will cause the asphalt raw materials to accumulate and affect the subsequent transportation of the asphalt raw materials.

[0008] During the transportation process, the asphalt raw materials will adhere to the outer surface of the conveyor belt. If the asphalt raw materials cannot be cleaned, it will not only affect the normal recovery effect of the asphalt raw materials, but also affect the subsequent transportation of the asphalt raw materials.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0041] like Figure 1-9 As shown, the asphalt raw material conveying belt includes a fixed structure 1, a conveying structure 2 is arranged inside the fixed structure 1, the fixed structure 1 supports and installs the conveying structure 2, and the height of the fixed structure 1 can be adjusted, so as to further improve the safety and stability of the conveying structure 2. At the same time, when the conveying structure 2 is working, it drives the asphalt raw material to be transmitted, so as to further improve the processing efficiency and processing quality of the asphalt raw material.

[0042] The fixed structure 1 includes a base 101, and a plurality of pneumatic height push rods 103 are evenly arranged on the top of the base 101. A top frame 107 is hinged on the top of the pneumatic height push rod 103, and a mounting plate 105 is arranged on the top of the top frame 107. When the pneumatic height push rod 103 is started and the output end is extended, the top frame 107 and the mounting plate 105 are driven to rise to different heights, thereby facilitating the transportation of asphalt raw materials at different heights.

[0043] A plurality of elastic pads 102 are evenly arranged at the bottom of the base 101. The elastic pads 102 are elastic. The setting of the elastic pads 102 improves the safety and stability of the support. A reinforcing rod 104 is arranged between adjacent bases 101. The reinforcing rod 104 further strengthens the strength between the plurality of bases 101. A controller 106 is arranged on one side of the mounting plate 105. The controller 106 electrically controls each electrical component. A plurality of pneumatic height push rods 103 are evenly distributed and match the inclination angles of 107. When the elongation lengths of the output ends of the plurality of pneumatic height push rods 103 are different, the plurality of top frames 107 and the mounting plate 105 are correspondingly driven to tilt, thereby realizing the upward transportation of the asphalt raw materials. The actual use status of the top frame 107 and the mounting plate 105 is adjusted according to different usage scenarios to further improve the transportation stability of the asphalt raw materials.

[0044] The conveying structure 2 includes a conveyor belt 205, which rotates continuously and realizes the conveyance of asphalt raw materials. A coupling 202 is provided on one side of the mounting plate 105, and a driving motor 201 is provided at the bottom input end of the coupling 202. An output end on one side of the coupling 202 passes through the mounting plate 105 and is provided with a driving shaft 203. The other end of the driving shaft 203 is rotatably connected to the side wall of the mounting plate 105 through a connecting bearing. The driving motor 201 is started and drives the driving shaft 203 to rotate through the coupling 202. A driven shaft 204 is provided on one side of the driving shaft 203. Both sides of the driven shaft 204 are rotatably connected to the facing end faces of the mounting plate 105 through connecting bearings. The conveyor belt 205 is transmission-connected to the outer surfaces of the driving shaft 203 and the driven shaft 204. The rotation of the driving shaft 203 drives the conveyor belt 205 to rotate, and the conveyor belt 205 synchronously drives the driven shaft 204 on the other side to rotate, thereby realizing the conveying effect of the conveyor belt 205.

[0045] A plurality of ventilation holes 206 are evenly arranged inside the conveyor belt 205. The arrangement of the ventilation holes 206 facilitates the wind flow inside the conveyor belt 205, thereby achieving wind cleaning of the conveyor belt 205 and avoiding contamination of subsequent asphalt raw material transmission.

[0046] The outer surface of the conveyor belt 205 is covered with a plurality of shielding sheets 207 which are stacked end to end. One side of the shielding sheet 207 is fixedly connected to the outer surface of the conveyor belt 205. Adjacent shielding sheets 207 are in contact with each other and match the outer surface of the conveyor belt 205. The shielding sheets 207 not only shield the ventilation holes 206 during transportation, but also when the shielding sheets 207 rotate to the end of the driving shaft 203, the shielding sheets 207 are subjected to the action of centrifugal force to throw out the asphalt raw materials above, thereby increasing the discharge speed of the asphalt raw materials.

[0047] A plurality of bearing seats 208 are evenly arranged on the top of the top frame 107, and two fastening bolts 210 are symmetrically arranged inside the bearing seats 208. The bottom of the fastening bolts 210 passes through the bearing seats 208 and is fixedly connected to the top of the top frame 107. The setting of the fastening bolts 210 further improves the stability and fixity of the bearing seats 208. A tensioning roller 209 is transmission-connected between adjacent bearing seats 208. The tensioning roller 209 is squeezed and transmitted with the outer surface of the conveyor belt 205. Therefore, the tensioning roller 209 not only performs a tensioning process on the conveyor belt 205 to ensure the stability and efficiency of the conveyor belt 205, but also can continuously squeeze and scrape with multiple shielding sheets 207 to improve the cleaning effect of the shielding sheets 207.

[0048] The leak-proof component is used for the above-mentioned asphalt raw material conveying belt, including multiple support structures 3, and an adjustment structure 4 is provided above the support structure 3. The support structure 3 provides lateral support to both sides of the bottom of the conveyor belt 205, and the adjustment structure 4 provides horizontal support to the bottom center direction of the conveyor belt 205. The support structure 3 and the adjustment structure 4 cooperate with each other and jointly realize the oblique support and transmission effect of the asphalt raw material above the conveyor belt 205.

[0049] The support structure 3 includes two rotating shafts 309, and the outer surface of the rotating shaft 309 is provided with side rollers 301, and the rotating shaft 309 supports and fixes the side rollers 301, and the outer surface of the side rollers 301 and the inner wall of the conveyor belt 205 are squeezed and contacted with each other to achieve the supporting transmission effect, and the side rollers 301 are provided with a splicing plate 304 below, and the splicing plate 304 is supported and fixed by the rotating shaft 309, and a bottom plate 305 is provided between two adjacent splicing plates 304, and two connecting seats 306 are symmetrically provided above the bottom plate 305, and the connecting seats 306 support the rotating shaft 309. One side of the moving shaft 309 is clamped and fixed, and a distance sensor 307 is provided on the top of the connecting seat 306. The distance sensor 307 is used to detect the distance value between the top of the connecting seat 306 and the bottom of the conveyor belt 205, so as to quickly obtain the amount of asphalt raw material above the conveyor belt 205. The height value of the distance sensor 307 is less than the height value above the air supply cylinder 401, and the distance sensor 307 is located at the corner of the air supply cylinder 401 and the side seat 301. This position can correspond to the accumulation of asphalt raw materials above the conveyor belt 205.

[0050] A side seat 302 is provided on the top of the two splicing plates 304 away from the connecting seat 306. The outer surfaces of the two sides of the rotating shaft 309 are respectively engaged with the inside of the side seat 302 and the connecting seat 306. The rotating shaft 309 will not rotate between the side seat 302 and the connecting seat 306. The outer surface of the side roller 301 is in contact with the inner wall of the conveyor belt 205 and is transmission-connected. The transmission stability and safety of the conveyor belt 205 are further improved by means of the transmission of the side roller 301. The two splicing plates 304 are inclined and have the same angle with the bottom plate 305. Multiple bottom plates 305 are horizontally arranged. Therefore, the conveyor belt 205 is an inverted isosceles trapezoidal structure during actual transmission. This transmission method avoids side leakage of asphalt raw materials above the conveyor belt 205, thereby improving the stability and integrity of the transmission.

[0051] A pad 303 is provided on the side of the two splicing plates 304 facing away from each other. A threaded hole 310 is provided inside the pad 303. The internal thread of the threaded hole 310 is connected with a fixing bolt 308. The bottom of the fixing bolt 308 passes through the threaded hole 310 and is fixedly connected with the top thread of the mounting plate 105. The setting of the fixing bolt 308 further improves the installation stability of the pad 303 and the mounting plate 105, and at the same time ensures the transmission support of the side roller 301 to the conveyor belt 205.

[0052] The adjusting structure 4 includes an air supply cylinder 401, the outer surface of which is in contact with the inner wall of the conveyor belt 205 and is transmission-connected, and the air supply cylinder 401 cooperates with the side rollers 301 to realize stable support and transmission of the conveyor belt 205, and a plurality of connecting holes 402 are evenly arranged inside the air supply cylinder 401, and the connecting holes 402 are used for the circulation of wind. The air supply cylinder 401 is symmetrically and slidingly connected with two sliding cylinders 405 inside, and the sliding cylinders 405 slide inside the air supply cylinder 401, and a plurality of docking holes 406 are evenly arranged inside the sliding cylinder 405, and the connecting holes 402 match the docking holes 406, so when the overlapping area of ​​the connecting holes 402 and the docking holes 406 increases, the wind flow rate inside the air supply cylinder 401 increases accordingly, and an air pump 408 is arranged at the axis of the air supply cylinder 401, and the air pump 408 is used for the circulation of gas.

[0053] Sealed bearings 403 are provided on the inner walls of both sides of the air supply tube 401, and a central axis rod 407 is provided inside the sealed bearings 403. The outer surfaces of the two central axis rods 407 on the opposite sides are mutually engaged with the inside of the connecting seat 306. The setting of the sealed bearings 403 ensures that the air supply tube 401 can stably rotate around the central axis rod 407, further improving the stability and sealing of the rotation of the air supply tube 401. The facing sides of the two central axis rods 407 are fixedly connected to the side walls of the air pump 408, and the central axis rod 407 supports and fixes the air pump 408. An exhaust pipe 409 is provided on the top of the air pump 408, and an exhaust pipe 410 is provided on the bottom of the air pump 408. When the air pump 408 is started and suction force is applied to the top along the exhaust pipe 409, the sucked gas is completely discharged along the exhaust pipe 410 at the bottom, thereby achieving gas flowability and cleanliness.

[0054] The outer surface of the sliding cylinder 405 is sealed and slidably connected to the inner wall of the air supply cylinder 401, so the sliding cylinder 405 can offset and block the air supply cylinder 401, thereby realizing the discharge of internal gas from the air supply cylinder 401. The side wall of the air supply cylinder 401 is evenly provided with multiple pneumatic adjustment push rods 404, and the output ends on the other sides of the pneumatic adjustment push rods 404 are fixedly connected to the side wall of the sliding cylinder 405. When the pneumatic adjustment push rods 404 are started and the output ends are extended, the output ends of the pneumatic adjustment push rods 404 drive the sliding cylinder 405 to move toward each other along the inner wall of the air supply cylinder 401, and the overlapping area between the connecting hole 402 and the docking hole 406 is increased, and the flow rate of internal gas in the air supply cylinder 401 is increased along this point, thereby further improving the adsorption and fixing effect on the bottom of the conveyor belt 205 and the wind cleaning effect on the outer surface of the shielding piece 207.

[0055] After the asphalt raw material is mixed, it needs to be subsequently conveyed. Due to the different feeding rates and amounts of the asphalt raw material, it is easy to cause the asphalt raw material to be unevenly distributed above the conveyor belt 205, which in turn causes the conveyor belt 205 to bend and deform, and ultimately affects the normal transmission efficiency of the asphalt raw material; and when the asphalt raw material accumulates on one side of the conveyor belt 205, the conveyor belt 205 will tilt to one side accordingly, and ultimately cause the asphalt raw material to leak sideways; at the same time, when the asphalt raw material above the conveyor belt 205 is transported to the end and unloaded, the unloading relying solely on the asphalt raw material's own gravity will cause the asphalt raw material to accumulate and affect the subsequent transportation of the asphalt raw material; and the asphalt raw material will adhere to the outer surface of the conveyor belt 205 during the transportation process. If the asphalt raw material cannot be cleaned, it will not only affect the normal recovery effect of the asphalt raw material, but also affect the subsequent transportation of the asphalt raw material.

[0056] In order to solve the above problems, when the asphalt raw material conveying belt and the leak-proof component used for the conveying belt are actually used, the controller 106 controls multiple pneumatic height push rods 103 to start and the output end extends, and the output end of the pneumatic height push rod 103 drives the top frame 107 and the mounting plate 105 to move upward to a suitable height, and the mounting plate 105 correspondingly drives the conveyor belt 205 between them to move upward to a corresponding height, thereby facilitating the subsequent transportation of the asphalt raw materials.

[0057] Then the controller 106 controls the driving motor 201 to start and drives the driving shaft 203 to rotate through the coupling 202. The driving shaft 203 cooperates with the driven shaft 204 to drive the conveyor belt 205 to rotate. At the same time, the conveyor belt 205 drives multiple shielding sheets 207 on the outer surface to transmit. At the same time, when the multiple shielding sheets 207 are located above the conveyor belt 205, the shielding sheets 207 are driven to fit together with the top of the conveyor belt 205 under the action of their own gravity, and the adjacent shielding sheets 207 contact each other, shielding The sheet 207 blocks the multiple ventilation holes 206 inside the conveyor belt 205. The top of the conveyor belt 205 is a flat surface. The stirring device stirs and mixes the asphalt raw materials and pours them onto the shielding sheet 207 close to the end of the driven shaft 204. The asphalt raw materials drive the conveyor belt 205 to tilt under the action of their own gravity. The two sides of the bottom of the conveyor belt 205 are respectively squeezed and contacted with the outer surfaces of the side rollers 301 and the air supply cylinder 401, thereby realizing the oblique transmission of the asphalt raw materials and avoiding the asphalt raw materials from tilting and causing side leakage.

[0058] The controller 106 controls the plurality of air pumps 408 to start, and the exhaust pipe 409 at the top of the air pump 408 applies suction force. Then, under the action of the suction force of the exhaust pipe 409, suction force is applied to the top of the air supply cylinder 401. At this time, the sliding cylinder 405 is in the initial position, and the connecting hole 402 and the docking hole 406 partially overlap. Under the action of the suction force of the exhaust pipe 409, suction force is applied to the conveyor belt 205 at the top of the air supply cylinder 401, and the inner wall of the conveyor belt 205 and the top of the air supply cylinder 401 are connected. The distance values ​​detected by the two distance sensors 307 both reach the preset distance values. At the same time, since the shielding sheet 207 blocks the multiple ventilation holes 206 inside the conveyor belt 205, the suction force ensures that the shielding sheet 207 and the outer surface of the conveyor belt 205 fit each other, avoiding the shielding sheet 207 from deviating due to the friction of the asphalt raw material, thereby causing the asphalt raw material to contaminate the conveyor belt 205, thereby effectively improving the transmission stability and efficiency of the asphalt raw material.

[0059] When the distance values ​​detected by the two distance sensors 307 at the corresponding positions decrease, it indicates that the amount of asphalt raw materials above the conveyor belt 205 at this position increases. Therefore, the distance value imposed by the asphalt raw materials on the conveyor belt 205 at this position decreases, thereby causing the conveyor belt 205 to bend downward and directly affecting the conveying stability of the conveyor belt 205. Therefore, the controller 106 controls the pneumatic adjustment push rod 404 at the corresponding position to start and shorten the output end. The output end of the pneumatic adjustment push rod 404 synchronously drives the sliding cylinder 405 to move in the reverse direction along the inside of the air supply cylinder 401. The sliding cylinder 405 synchronously drives the multiple docking holes 406 to move, and the overlapping area between the docking holes 406 and the connecting holes 402 is reduced. The air pump 408 is started and under the suction force applied by the top exhaust pipe 409, the suction force applied by the multiple connecting holes 402 to the bottom of the conveyor belt 205 is reduced. The conveyor belt 205 is bent downward under the suction force, and the amount of deformation is reduced, thereby ensuring that the conveyor belt 205 is in a horizontal position, thereby improving the conveying stability and efficiency of the conveyor belt 205 for the asphalt raw materials.

[0060] Similarly, when the distance values ​​detected by the two distance sensors 307 at the corresponding positions increase and are greater than the preset distance values, it indicates that the amount of asphalt raw materials at this position decreases, and the corresponding controller 106 controls the pneumatic adjustment push rod 404 to start and the output end to extend, and the output end of the pneumatic adjustment push rod 404 drives the sliding cylinder 405 to move toward each other along the inside of the air supply cylinder 401, and the overlapping area of ​​the connecting hole 402 and the docking hole 406 increases. Then, under the suction force of the exhaust pipe 409 at the top of the air pump 408, the suction force applied by the connecting hole 402 to the bottom of the conveyor belt 205 increases, and the conveyor belt 205 bends downward, further ensuring the stability and smoothness of the conveyor belt 205.

[0061] As the air pump 408 continues to work, the multiple connecting holes 402 inside the air supply cylinder 401 can filter and remove impurities from the gas circulating from the outside, further preventing impurities from affecting the transmission of the conveyor belt 205. At the same time, when the sliding cylinder 405 moves inside the air supply cylinder 401, the outer surface of the sliding cylinder 405 can scrape and clean the impurities blocked inside the connecting holes 402 inside the air supply cylinder 401, further improving the fluidity of the gas inside the connecting holes 402. At the same time, with the continuous rotation of the air supply cylinder 401, the wind direction and wind force applied to the multiple connecting holes 402 by the gas inside the air pump 408 after passing through the docking hole 406 inside the sliding cylinder 405 will change accordingly, thereby further improving the wind clearing effect.

[0062] At the same time, when the distance values ​​detected by the two distance sensors 307 at the same position are not equal, it means that the asphalt raw materials above the conveyor belt 205 are unevenly distributed at this time, and the conveyor belt 205 is prone to tilt and eventually leak under the gravity of the asphalt raw materials. Therefore, when the distance value detected by the distance sensor 307 on one side decreases, while the distance value detected by the distance sensor 307 on the other side increases, it means that the asphalt raw materials above the conveyor belt 205 are tilted toward the side where the distance value detected by the distance sensor 307 decreases. Then, the controller 106 controls the pneumatic adjustment push rod 404 on the side where the distance value detected by the distance sensor 307 decreases, and the output end is shortened. The output end of the pneumatic adjustment push rod 404 drives the sliding cylinder 405 on this side to move backward, and the sliding cylinder 405 drives the multiple docking holes 406 to move, and the overlapping area of ​​the docking holes 406 and the connecting holes 402 is reduced. The exhaust pipe 409 above the air pump 408 reduces the suction force on this side of the conveyor belt 205 through the connecting holes 402.

[0063] The controller 106 controls the pneumatic adjustment push rod 404 on the side where the distance value detected by the distance sensor 307 increases to start and extend the output end, and the output end of the pneumatic adjustment push rod 404 drives the sliding cylinder 405 on this side to move toward each other, and the sliding cylinder 405 drives the multiple docking holes 406 to move, and the overlapping area of ​​the docking holes 406 and the connecting holes 402 increases. The exhaust pipe 409 above the air pump 408 increases the suction force on this side of the conveyor belt 205 through the connecting holes 402. Then, the conveyor belt 205 tilts toward the side where the distance value detected by the distance sensor 307 increases under the action of different suction forces at the bottom, and the asphalt raw material above the conveyor belt 205 slides synchronously toward the side where the distance value detected by the distance sensor 307 increases under the action of its own gravity, thereby ensuring that the asphalt raw material above the conveyor belt 205 is evenly and flatly distributed, thereby improving the stability and efficiency of the asphalt raw material transmission by the conveyor belt 205.

[0064] As the conveyor belt 205 continuously drives the asphalt raw material to be conveyed and reaches the end of the driving shaft 203, the asphalt raw material needs to undergo a subsequent unloading process. The conveyor belt 205 drives the shielding plate 207 to rotate to the side of the driving shaft 203 away from the driven shaft 204. At this time, since the conveyor belt 205 is separated from the suction effect of the multiple air supply tubes 401 and the centrifugal force exerted on the shielding plate 207, the shielding plate 207 throws the asphalt raw material above away from the driven shaft 204. The asphalt raw material flies out under the combined action of its own gravity and the throwing force of the shielding plate 207, further increasing the unloading range of the asphalt raw material above the shielding plate 207, avoiding accumulation of the asphalt raw material during unloading and affecting the subsequent unloading efficiency, thereby ensuring the unloading quality and unloading effect.

[0065] Afterwards, as the conveyor belt 205 continues to rotate, the conveyor belt 205 drives multiple shielding plates 207 to be transmitted downward. Under the action of its own gravity, the shielding plates 207 are separated from the outer surface of the conveyor belt 205 and are in a vertical state. At this time, the air pump 408 is started and the exhaust pipe 410 below continuously discharges gas. The gas goes down along the overlapping area of ​​the connecting hole 402 and the docking hole 406 to the bottom of the conveyor belt 205. At this time, since the shielding plates 207 are in the initial vertical state and are free from the blockage of the ventilation holes 206, the gas passes through multiple ventilation holes 206 and flows to the outer surface of the shielding plates 207. With the help of the wind force, the wind cleaning effect of the outer surface of the shielding plates 207 is further improved, thereby avoiding impurities attached to the outer surface of the shielding plates 207 and affecting the subsequent transmission of asphalt raw materials.

[0066] At the same time, when the distance value detected by the distance sensor 307 changes, the multiple pneumatic adjustment push rods 404 drive the sliding cylinder 405 to move inside the air supply cylinder 401, and the sliding cylinder 405 drives the multiple docking holes 406 to move synchronously, and the overlapping area of ​​the docking holes 406 and the connecting holes 402 changes. The gas discharged from the exhaust pipe 410 below the air pump 408 passes through the overlapping area of ​​the docking holes 406 and the connecting holes 402 and reaches the bottom of the conveyor belt 205, and the wind force applied to the outer surface of the shielding piece 207 along the multiple ventilation holes 206 is constantly changing, further realizing the pulse wind cleaning effect on the outer surface of the shielding piece 207, and the shielding piece 207 will synchronously vibrate at high frequency under the action of the pulse wind, thereby improving the wind vibration cleaning of impurities attached to the outer surface of the shielding piece 207, with stronger adaptability and higher impurity removal efficiency.

[0067] As the conveyor belt 205 is continuously conveyed and passes through multiple pulse cleaning of the air supply cylinders 401, the shielding sheet 207 reaches the end of the driven shaft 204. At this time, the shielding sheet 207 is continuously attached to the outer surface of the conveyor belt 205 under the action of its own weight and blocks multiple ventilation holes 206. At the same time, adjacent shielding sheets 207 are connected end to end and continuously move to the top of the conveyor belt 205. At this time, the above process is repeated to convey and prevent leakage of subsequent asphalt raw materials, thereby improving the transmission efficiency and transmission stability of the asphalt raw materials.

[0068] The asphalt raw material conveying belt and the leak-proof component have high transmission efficiency and good transmission effect, meet the actual demand for stable transmission of asphalt raw materials, are simple to operate, safe and stable, highly adaptable and controllable; and can also detect the amount and position of asphalt raw materials above the conveyor belt 205 in real time, and adjust the adsorption force on the inner wall of the conveyor belt 205 accordingly, so as to ensure the smooth and safe transmission of the conveyor belt 205, with higher levelness, better uniformity and stronger operability; and when the conveyor belt 205 drives the asphalt raw materials to the end and unloads, the asphalt raw materials are thrown out with the help of the centrifugal force exerted on the shielding sheet 207, so as to effectively ensure the uniformity of the unloading of the asphalt raw materials, avoid the accumulation of asphalt raw materials and affect the normal transmission of subsequent asphalt raw materials; at the same time, after the unloading of the asphalt raw materials is completed, the shielding sheet 207 in the vertical state is subjected to the action of pulse wind force to vibrate at high frequency, thereby realizing the wind vibration cleaning of impurities attached to the outer surface of the shielding sheet 207, with higher cleaning efficiency and better cleaning effect, ensuring the stability of the subsequent shielding sheet 207 in supporting the transmission of the asphalt raw materials.
