Description

Technical Field

[0001] This utility model relates to the technical field of solid asphalt conveying equipment, and in particular to a solid asphalt lifting and conveying device. Background Technology

[0002] Asphalt is a complex, dark brown mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form. Currently, bucket elevators are commonly used for lifting and conveying solid asphalt. Their lifting principle involves an electric motor driving a transmission device, causing the buckets to move up and down along traction components (such as chains or belts), thus achieving continuous material lifting and conveying. However, in actual bucket elevator operation, some of the solid asphalt entering and exiting the elevator casing through the inlet and outlet falls outside the buckets due to angle and time constraints, accumulating at the bottom of the casing. This accumulated asphalt not only collides with the buckets, affecting their movement, but also, after cooling at the bottom of the casing, easily adheres tightly to the bottom wall, making manual cleaning extremely difficult. Utility Model Content

[0003] The purpose of this invention is to provide a solid asphalt lifting and conveying device that has the effect of automatically cleaning and recycling asphalt at the bottom of the machine casing.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A solid asphalt lifting and conveying device includes a housing, an inlet and an outlet respectively disposed on both sides of the housing, a pair of upper and lower conveyor belt rollers parallel to each other and rotatably disposed inside the housing, a drive mechanism for driving the upper conveyor belt rollers to rotate, a conveyor belt sleeved on the upper and lower conveyor belt rollers, a plurality of buckets uniformly fixed on the outer side of the conveyor belt, a rotating shaft rotatably disposed inside the housing and parallel to the lower conveyor belt roller, a drive mechanism for driving the rotating shaft to rotate, a spiral blade fixed on the outer contour surface of the rotating shaft, a groove disposed at the top of the housing for the spiral blades to rotate, a discharge port opened on one side of the housing and penetrating one end of the groove, and a collection box for receiving the asphalt discharged from the discharge port.

[0005] The feed inlet and discharge outlet are located on both sides of the conveyor belt, between the upper conveyor belt roller and the lower conveyor belt roller, and the height of the discharge outlet is higher than the height of the feed inlet. The bucket opening on the side of the conveyor belt near the feed inlet faces upward, and the bucket opening on the side of the conveyor belt near the discharge outlet faces downward. The bottom of the groove is semi-circular, and the rotating shaft and the semi-circular bottom of the groove are coaxial. The outer contour surface of the spiral blade and the semi-circular bottom of the groove are in contact and rub against each other.

[0006] A further feature of this invention is that the drive mechanism includes a motor fixed to the top of the housing, a sprocket fixed to the output end of the motor, a sprocket fixed to one end of the upper conveyor belt roller, and a chain sleeved and installed on the sprocket and the sprocket. The sprocket and the chain are located outside the housing, and one end of the upper conveyor belt roller rotates through the side wall of the housing to connect to the sprocket.

[0007] A further feature of this invention is that a protective cover is fixedly provided on the side wall of the housing to cover the first sprocket, the second sprocket, and the first chain.

[0008] A further configuration of this utility model is as follows: the second drive mechanism includes a third sprocket fixed to one end of the lower conveyor belt roller, a fourth sprocket fixed to one end of the rotating shaft, and a second chain sleeved and installed on the third and fourth sprockets. The third sprocket, the fourth sprocket, and the second chain are located outside the machine housing. One end of the lower conveyor belt roller and the rotating shaft rotates through the side wall of the machine housing and is respectively connected to the third sprocket and the fourth sprocket.

[0009] A further feature of this invention is that a protective cover 2 is fixedly provided on the side wall of the housing to cover the sprocket 3, sprocket 4 and chain 2.

[0010] A further feature of this invention is that the collection box is located below the inlet, and a lifting mechanism is provided on one side of the casing to lift and transfer the asphalt discharged from the discharge port into the collection box. The lifting mechanism includes a triangular box fixed to the side wall of the casing with its opening facing upward, a roller 1 rotatably mounted on the top of the triangular box, a pair of rollers 2 and 3 respectively fixed to the lower conveyor belt roller and one end of the rotating shaft, a conveyor belt 2 sleeved on rollers 1, 2, and 3, and multiple pusher plates uniformly and vertically fixed to the outer contour surface of the conveyor belt 2. The discharge port communicates with the interior of the triangular box, and the rollers 2 are located... At the top of the triangular box, roller three is located inside the triangular box, and one end of the lower conveyor belt roller and the rotating shaft rotates out through the side wall of the machine casing to connect roller two and roller three. The conveyor belt two is triangular in shape and partially moves inside the triangular box. The triangular box is a right triangle, with the end near roller two being a right angle and the end near roller three having an arc-shaped rounded corner. The end of the triangular box away from roller two and roller three is located above the collection box, and roller one is close to this end. The side of the pusher plate away from conveyor belt two is in contact with the inner contour surface of the triangular box and moves along the trajectory of the inner contour surface of the triangular box.

[0011] A further feature of this invention is that a U-shaped feeding trough is fixedly provided at one end of the triangular box located above the collection box, and the outlet of the U-shaped feeding trough is inclined towards the inside of the collection box.

[0012] A further feature of this invention is that the discharge port is semi-circular in shape and located below the roller three.

[0013] A further feature of this invention is that multiple circular holes are uniformly formed on the two surfaces of the conveyor belt, the circular holes being located between adjacent pusher plates and allowing asphalt solid particles to pass through.

[0014] A further feature of this invention is that: four omnidirectional casters are fixedly installed at the bottom of the collection box, and the four omnidirectional casters are respectively close to the four corners of the collection box; and handrails are fixedly installed on both sides of the collection box.

[0015] The beneficial effects of this utility model are as follows: By employing the above-mentioned lifting and conveying device, when solid asphalt needs to fall out of the hopper, it will slide along the inner wall of the machine casing into the groove. Then, the rotating shaft drives the spiral blades to rotate. Due to the contact and friction between the outer contour surface of the spiral blades and the semi-circular bottom of the groove, the solid asphalt that has fallen into the groove will be continuously pushed by the spiral blades under the rotation of the rotating shaft until it leaves from the discharge port at one end of the groove, thereby achieving the effect of automatically cleaning the solid asphalt at the bottom of the machine casing. Then, the solid asphalt coming out of the discharge port will enter the triangular box, and because of the rollers... Two rollers and three rollers are respectively connected to one end of the lower conveyor belt roller and the rotating shaft, and rotate together with both. Therefore, the second conveyor belt will move relative to the triangular box, and drive the pusher plate on its outer wheel surface to move along the inner contour trajectory of the triangular box. At the same time, the solid asphalt entering the triangular box will be pushed by the pusher plate and move upward along the inner slope of the triangular box. Finally, when the pusher plate pushing the solid asphalt reaches the height of the U-shaped discharge chute, the solid asphalt will leave the triangular box along the inclined posture of the U-shaped discharge chute and slide into the collection box, thus completing the automatic recycling effect of solid asphalt.

[0016] The above-mentioned automatic cleaning and recycling process for solid asphalt is continuous and efficient. It not only avoids the accumulation of solid asphalt at the bottom of the machine casing, which would affect the operation of the bucket, but also eliminates concerns about solid asphalt naturally cooling and adhering to the inner wall of the machine casing due to the fast cleaning and recycling speed and short time.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: A solid asphalt lifting and conveying device, such as Figure 1-4As shown, the system includes a housing 1, an inlet 11 and an outlet 12 respectively located on both sides of the housing 1, a pair of upper conveyor belt rollers 2 and lower conveyor belt rollers 3 that are parallel to each other and rotatably disposed inside the housing 1, a drive mechanism 4 for driving the upper conveyor belt rollers 2 to rotate, a conveyor belt 5 sleeved on the upper conveyor belt rollers 2 and lower conveyor belt rollers 3, multiple buckets 6 evenly fixed on the outer surface of the conveyor belt 5, a rotating shaft 7 rotatably disposed inside the housing 1 and parallel to the lower conveyor belt rollers 3, a drive mechanism 8 for driving the rotating shaft 7 to rotate, a spiral blade 9 fixed on the outer contour surface of the rotating shaft 7, and a spiral blade 9 disposed at the top inside the housing 1 for rotating and moving. The groove 13, the discharge port 14 opened on one side of the housing 1 and passing through one end of the groove 13, the collection box 10 for receiving the asphalt discharged from the discharge port 14, the inlet 11 and the outlet 12 are located on both sides of the conveyor belt 5, between the upper conveyor belt roller 2 and the lower conveyor belt roller 3, and the height of the outlet 12 is higher than the height of the inlet 11. The bucket 6 on the side of the conveyor belt 5 near the inlet 11 has its opening facing upward, and the bucket 6 on the side of the conveyor belt 5 near the outlet 12 has its opening facing downward. The bottom of the groove 13 is semi-circular, and the rotating shaft 7 and the semi-circular bottom of the groove 13 are coaxial. The outer contour surface of the spiral blade 9 and the semi-circular bottom of the groove 13 are in contact and rub against each other.

[0025] Furthermore, the drive mechanism 4 includes a motor 41 fixed to the top of the housing 1, a sprocket 42 fixed to the output end of the motor 41, a sprocket 43 fixed to one end of the upper conveyor belt roller 2, and a chain 44 sleeved and installed on the sprocket 42 and the sprocket 43. The sprocket 43 and the chain 44 are located outside the housing 1, and one end of the upper conveyor belt roller 2 rotates through the side wall of the housing 1 and connects to the sprocket 43. The drive mechanism 8 includes a sprocket 81 fixed to one end of the lower conveyor belt roller 3, a sprocket 82 fixed to one end of the rotating shaft 7, and a chain 83 sleeved and installed on the sprocket 81 and the sprocket 82. The sprocket 81, the sprocket 82 and the chain 83 are located outside the housing 1. One end of the lower conveyor belt roller 3 and the rotating shaft 7 rotates through the side wall of the housing 1 and connects to the sprocket 81 and the sprocket 82 respectively. By adopting a chain drive structure, not only is the transmission stable and efficient, but it is also easy to maintain and has low operating costs.

[0026] Furthermore, a protective cover 45 is fixedly installed on the side wall of the housing 1 to cover sprocket 42, sprocket 43, and chain 44, and a protective cover 84 is fixedly installed on the side wall of the housing 1 to cover sprocket 81, sprocket 82, and chain 83. By using the above-mentioned protective covers 45 and 84, not only can the chain drive structure be simply protected, but it can also effectively prevent workers from being accidentally injured by the moving chain and sprockets.

[0027] Furthermore, the collection box 10 is located below the inlet 11. A lifting mechanism 1a is provided on one side of the casing 1 to lift and transfer the asphalt discharged from the discharge port 14 into the collection box 10. The lifting mechanism 1a includes a triangular box 1a1 fixed to the side wall of the casing 1 with its opening facing upwards, a roller 1a2 rotatably mounted on the top of the triangular box 1a1, a pair of rollers 1a3 and 1a4 respectively fixed to one end of the lower conveyor belt roller 3 and the rotating shaft 7, a second conveyor belt 1a5 sleeved on the rollers 1a2, 1a3, and 1a4, and multiple pusher plates 1a6 uniformly and vertically fixed to the outer contour surface of the second conveyor belt 1a5. The discharge port 14 connects to the interior of the triangular box 1a1, and the roller 1a3 is located within the triangular box. The top of body 1a1 and roller 3 1a4 are located inside the triangular box 1a1. One end of the lower conveyor belt roller 3 and the rotating shaft 7 rotates out of the side wall of the housing 1 and connects to roller 2 1a3 and roller 3 1a4. The second conveyor belt 2 1a5 is triangular in shape and partially moves inside the triangular box 1a1. The triangular box 1a1 is a right triangle, with the end near roller 2 1a3 being a right angle and the end near roller 3 1a4 having an arc-shaped rounded corner. The end of the triangular box 1a1 away from roller 2 1a3 and roller 3 1a4 is located above the collection box 10, and roller 1 1a2 is close to this end. The side of the pusher plate 1a6 away from the second conveyor belt 2 is in contact with the inner contour surface of the triangular box 1a1 and moves along the trajectory of the inner contour surface of the triangular box 1a1.

[0028] By adopting the above-mentioned lifting mechanism 1a, not only can the solid asphalt discharged from the discharge port 14 be lifted and transported into the collection box 10, but the rotation of the roller and the movement of the conveyor belt 1a5 are driven by the rotation of the rotating shaft 7 and the lower conveyor belt roller 3. Therefore, this mechanism does not require an additional power supply and has low manufacturing and usage costs.

[0029] Furthermore, a U-shaped discharge chute 1a7 is fixedly installed at one end of the triangular box 1a1 located above the collection box 10, with the outlet of the U-shaped discharge chute 1a7 inclined towards the interior of the collection box 10. By adopting the aforementioned U-shaped discharge chute 1a7, it is possible to ensure that solid asphalt smoothly enters the collection box 10.

[0030] Furthermore, the discharge port 14 is semi-circular in shape and located below the roller 1a4. By adopting the above-described shape of the discharge port 14, it is possible to effectively prevent solid asphalt from entering the inner space of the conveyor belt 1a5.

[0031] Furthermore, multiple circular holes are evenly distributed on the surface of conveyor belt 1a5, located between adjacent pusher plates 1a6, allowing asphalt solid particles to pass through. By using these circular holes, solid asphalt can be prevented from getting stuck on conveyor belt 1a5.

[0032] Furthermore, four swivel casters 101 are fixedly installed at the bottom of the collection box 10, and the four swivel casters 101 are respectively located near the four corners of the collection box 10. Handrails 102 are fixedly installed on both sides of the collection box 10. By using the aforementioned swivel casters 101 and handrails 102, it is convenient for staff to move and lift the collection box 10.

[0033] The working principle of this embodiment:

[0034] When solid asphalt needs to fall out of the hopper 6, it will slide along the inner wall of the casing 1 into the groove 13. Then, the rotating shaft 7 drives the spiral blades 9 to rotate. Because the outer contour surface of the spiral blades 9 and the semi-circular bottom of the groove 13 come into contact and rub against each other, the solid asphalt that has slid into the groove 13 will be continuously pushed by the spiral blades 9 under the rotation of the rotating shaft 7 until it leaves from the discharge port 14 at one end of the groove 13, thus achieving the effect of automatically cleaning the solid asphalt at the bottom of the casing 1. Then, the solid asphalt coming out of the discharge port 14 will enter the triangular box 1a1. Since rollers 2 1a3 and rollers 3 1a4 are respectively connected to the lower conveyor belt rollers 3 and 4a1, the solid asphalt will be discharged into the triangular box 1a1. One end of the rotating shaft 7 rotates together with the other two, so the conveyor belt 1a5 moves relative to the triangular box 1a1 and drives the pusher plate 1a6 on its outer wheel surface to move along the internal contour of the triangular box 1a1. At the same time, the solid asphalt entering the triangular box 1a1 is pushed by the pusher plate 1a6 and moves upward along the internal slope of the triangular box 1a1. Finally, when the pusher plate 1a6 pushing the solid asphalt reaches the height of the U-shaped discharge chute 1a7, the solid asphalt will leave the triangular box 1a1 along the inclined posture of the U-shaped discharge chute 1a7 and slide into the collection box 10, thus completing the automatic recycling effect of solid asphalt.
