Description

[0002] Rubber asphalt is a modified asphalt material, usually prepared by grinding waste tires into powder and mixing it into ordinary asphalt; this material combines the elastic properties of rubber and the viscous characteristics of asphalt, giving it better performance than traditional asphalt, such as higher high-temperature stability, better low-temperature flexibility, stronger resistance to aging and fatigue, and improved resistance to water damage.

DETAILED DESCRIPTION

[0039] 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.

[0040] like Figure 1-8 As shown, a feeding mechanism, such as Figure 1-2 and Figure 5As shown, it includes a collecting hopper 1; the collecting hopper 1 is provided with a material guiding mechanism 2; the material guiding mechanism 2 includes: a first mounting frame 21, the first mounting frame 21 is installed on the collecting hopper 1; a lower hopper 22, the lower hopper 22 is installed on the first mounting frame 21; a material guiding cylinder 23, the material guiding cylinder 23 is arranged on the first mounting frame 21, one end of the material guiding cylinder 23 is tilted downward and extends into the collecting hopper 1; a connecting hose 24, the connecting hose 24 is arranged between the lower hopper 22 and the material guiding cylinder 23, and the bottom of the lower hopper 22 is connected to the connecting hose 24 through the connecting hose The inside of the material guide barrel 23 is connected; it can be understood that the connecting hose 24 is a bellows structure, so that when the connecting hose 24 is bent under force, its inner diameter can remain unchanged, allowing the material to pass through; the control mechanism 25, the control mechanism 25 is arranged on the material guide barrel 23; the material guide barrel 23 is used to control the discharge speed of the material in the material guide barrel 23; and the adjustment mechanism 26, the adjustment mechanism 26 is arranged between the first mounting frame 21 and the material guide barrel 23; the adjustment mechanism 26 is used to control the relative position of the discharge end of the material guide barrel 23 in the collecting bucket 1.

[0041] It should be noted that when in use, the material is introduced into the downward hopper 22, so that the material is introduced into the material guide barrel 23 through the connecting hose 24. Since the material guide barrel 23 is inserted into the collecting bucket 1 in a downward tilted state, under the action of gravity, the material is introduced into the collecting bucket 1 along the material guide barrel 23. The inclined setting of the material guide barrel 23 can reduce the initial speed of the material when it is introduced into the collecting bucket 1, thereby reducing the impact force when the material is discharged, reducing the problem of material fragmentation caused by the drop during the feeding process, and thus reducing the impact on the next step of material mixing.

[0042] In the process of introducing the material into the collecting hopper 1 through the material guide cylinder 23, the conveying speed of the material in the material guide cylinder 23 is controlled by the control mechanism 25, thereby controlling the initial feeding speed, further reducing the problem of material fragmentation caused by the drop during the feeding process, and ensuring the feeding efficiency of the material;

[0043] In the process of introducing the material into the collecting bucket 1 through the material guide cylinder 23, as the material accumulates in the collecting bucket 1, the material guide cylinder 23 is driven to rotate through the adjustment mechanism 26 to drive the outlet end of the material guide cylinder 23 to move upward, so as not to affect the material feeding speed while ensuring that the accumulation of the material in the collecting bucket 1 does not affect the outlet of the material in the material guide cylinder 23, that is, to control the distance between the outlet end of the material guide cylinder 23 and the material accumulation height.

[0044] like Figure 1-2 and Figure 5 As shown, the control mechanism 25 includes a spiral blade 251 coaxially rotatably connected to the material guide barrel 23 and a motor 252 mounted on the material guide barrel 23 ; the output end of the motor 252 is coaxially connected to the spiral blade 251 .

[0045] It should be noted that the purpose of controlling the material conveying speed in the material guide barrel 23 is achieved by driving the spiral blade 251 to rotate through the motor 252; specifically, when the material guide barrel 23 is tilted downward at a large angle, that is, in the initial feeding stage, the spiral blade 251 can be driven by the motor 252 to rotate in the opposite direction, so that the spiral blade 251 forms an upward thrust on the material; at this time, since the material guide barrel 23 is tilted downward at a large angle, the component force of the material gravity on the axis of the material guide barrel 23 is large, so the material will be driven to be conveyed in the material guide barrel 23 at a faster speed. Therefore, by driving the spiral blade 251 to rotate in the opposite direction, a thrust is formed on the material toward the inlet end of the material guide barrel 23 to offset a part of the component force of the material gravity on the axis of the material guide barrel 23, thereby achieving the purpose of slowing down the material conveying speed in the material guide barrel 23;

[0046] As the adjusting mechanism 26 controls the outlet end of the material guide barrel 23 to rotate upward continuously, the downward inclination angle of the material guide barrel 23 is continuously reduced. At this time, the rotation speed of the spiral blade 251 can be slowed down by the motor 252 to ensure that the material has a suitable conveying speed in the material guide barrel 23, prevent the material from being discharged too quickly, and ensure the feeding efficiency; as the adjusting mechanism 26 drives the material guide barrel 23 to rotate further upward, the component of the material gravity on the axis of the material guide barrel 23 is too small, that is, the material conveying speed in the material guide barrel 23 is too slow. At this time, the spiral blade 251 can be driven by the motor 252 to rotate forward, forming a thrust to the outlet end of the material guide barrel 23, providing assistance for the material to be discharged from the material guide barrel 23, thereby accelerating the material discharge efficiency.

[0047] like Figure 1-3 and Figure 6 As shown, the adjustment mechanism 26 includes a rotating shaft 261 and a cylinder 263; the rotating shaft 261 is arranged on the material guide barrel 23, and the axis of the rotating shaft 261 is perpendicular to the axis of the material guide barrel 23; the cylinder 263 is arranged between the collecting bucket 1 and the rotating shaft 261, and a slide groove 262 is provided on the first mounting frame 21; the cylinder 263 is an arc structure; the rotating shaft 261 is slidably connected to the slide groove 262, and one end of the rotating shaft 261 passes through the slide groove 262 and is rotatably connected to the output end of the cylinder 263; the cylinder 263 is used to push the rotating shaft 261 to slide along the cylinder 263; the adjustment mechanism 26 also includes a gear 264 and a rack 265; the gear 264 is coaxially arranged on the rotating shaft 261, and the rack 265 is arranged on the first mounting frame 21; when the rotating shaft 261 slides in the slide groove 262, it can drive the gear 264 to engage with the rack 265.

[0048] It should be noted that as the material accumulates in the collecting hopper 1, as the material accumulation height approaches the outlet end of the guide barrel 23, the adjusting mechanism 26 is used to control the guide barrel 23 to rotate, so that a certain distance is always maintained between the outlet end of the guide barrel 23 and the material accumulation height, and this distance will not cause the material to break due to a large drop, nor will the short distance affect the outlet of the material; specifically, the cylinder 263 pushes the rotating shaft 261 to move, so that the rotating shaft 261 slides in the slide groove 262, thereby driving the guide barrel 23 to move along the arc trajectory of the slide groove 262, so that the outlet end of the guide barrel 23 moves obliquely upward from the center position of the collecting hopper 1 to the outside of the collecting hopper 1, while driving the outlet end of the guide barrel 23 to maintain a certain distance from the material accumulation height in the collecting hopper 1, so that the outlet end of the guide barrel 23 moves from the center position of the collecting hopper 1 to the outside, so that the accumulated materials in the collecting hopper 1 are relatively flat;

[0049] As the cylinder 263 continues to push the rotating shaft 261 to move, the gear 264 is driven to engage with the rack 265. At this time, as the rotating shaft 261 continues to move, under the restriction of the rack 265, the gear 264 is driven to rotate, and then the material guide barrel 23 is driven to rotate upward. That is, in this process, the material guide barrel 23 moves upward and the lead-out end of the material guide barrel 23 rotates upward. At this time, the lead-out end of the material guide barrel 23 moves from a position close to the inner wall of the collecting bucket 1 to the center of the collecting bucket 1. In this way, during the process of feeding the material into the collecting bucket 1, the top of the material can be ensured to be in a relatively flat state, so as to improve the space utilization and reduce the influence of the material accumulated in the collecting bucket 1 on the lead-out of the material in the material guide barrel 23.

[0050] like Figure 1-4 As shown, an isolation cover 3 is provided on the collecting bucket 1, and an offset hole 266 is opened on the isolation cover 3. One end of the material guide tube 23 passes through the offset hole 266 and is inserted into the collecting bucket 1; an elastic cloth 267 is provided on the offset hole 266, and the elastic cloth 267 is connected to the material guide tube 23; the elastic cloth 267 is used to block the offset hole 266 to isolate the inside and outside of the collecting bucket 1.

[0051] It should be noted that during the feeding process, dust pollution is easily caused as the material is discharged. Therefore, an isolation cover 3 and an elastic cloth 267 structure are provided to achieve a relative isolation state between the collecting bucket 1 and the outside world without affecting the normal movement of the material guide cylinder 23, thereby reducing dust flying.

[0052] like Figure 2-4 and Figure 7-8As shown, the material guiding mechanism 2 also includes a cooling mechanism 27, which is arranged on the material guiding cylinder 23; the cooling mechanism 27 is used to reduce the working temperature of the control mechanism 25; the cooling mechanism 27 includes a cooling pipe 271, a second mounting bracket 272, a water inlet pipe 273 and a water outlet pipe 274; the cooling pipe 271 is sleeved on the material guiding cylinder 23, a through hole is opened on the top of the isolation cover 3, the second mounting bracket 272 is installed on the through hole, the water inlet pipe 273 and the water outlet pipe 274 are both arranged on the second mounting bracket 272, one end of the cooling pipe 271 is connected to the water inlet pipe 273, and the other end of the cooling pipe 271 is connected to the water outlet pipe 274; the water inlet pipe 273 includes a straight pipe and a first spring hose; the straight pipe is arranged on the second mounting bracket 272, and the straight pipe is used to connect with the outside world; the first spring hose is arranged between the cooling pipe 271 and the second mounting bracket 272; the water outlet pipe 274 is a second spring hose structure.

[0053] It should be noted that, during the process of the spiral blade 251 rotating to transport the material, friction will occur between the spiral blade 251 and the material guide barrel 23, causing the temperature to rise, and some materials will be affected by the temperature, causing the viscosity of the materials to increase, thereby affecting the material transportation. Therefore, a cooling mechanism 27 is provided to achieve cooling and reduce the impact of the temperature increase during material transportation; specifically, by surrounding a cooling pipe 271 on the outside of the material guide barrel 23, the cooling pipe 271 is an S-shaped curved structure surrounding the outer wall of the material guide barrel 23. When cold water is introduced into the cooling pipe 271 through the water inlet pipe 273, the S-shaped structure of the cooling pipe 271 slows down the flow rate of the cold water in the cooling pipe 271, and at the same time increases the cooling area between the cooling pipe 271 and the material guide barrel 23, thereby improving the cooling effect; it can be understood that by providing the spring hose structure of the water inlet pipe 273 and the water outlet pipe 274, the material guide barrel 23 can be continuously cooled when the material guide barrel 23 is in motion, thereby ensuring the cooling effect.

[0054] like Figure 2-4 and Figure 7-8 As shown, the cooling mechanism 27 also includes a dust reduction mechanism 275; the dust reduction mechanism 275 includes a nozzle 2751 and a guide cover 2752; the nozzle 2751 is arranged on the second mounting frame 272, and one end of the water outlet pipe 274 is connected to the second mounting frame 272; the guide cover 2752 is arranged at the through hole position on the isolation cover 3; the guide cover 2752 is used to collect the water flow sprayed by the nozzle 2751.

[0055] It should be noted that, in the process of feeding materials into the collecting bucket 1, it is necessary to set an air outlet at the top of the collecting bucket 1 to reduce the influence of air pressure on the introduction of materials. However, the setting of the air outlet will cause dust to fly from the air outlet to the outside, causing dust pollution. Therefore, a dust reduction mechanism 275 is set to be used in conjunction with the cooling mechanism 27 to spray the cooled water to the air outlet position to achieve the purpose of dust reduction; specifically, the cooling water discharged through the water outlet pipe 274 is sprayed out through the nozzle 2751, and the inverted umbrella-shaped structure of the sprayed cooling water forms a conical water curtain that blocks the air outlet position and is collected by the guide cover 2752; when dust flies from the air outlet, the cooling water sprayed from the nozzle 2751 contacts the dust, and is collected by the guide cover 2752 carrying the dust. In this way, the purpose of using the water after cooling to reduce dust is achieved.

[0056] like Figure 4 As shown, the guide cover 2752 is a top opening structure; the guide cover 2752 includes a guide section 27521 and an isolation section 27522; the guide section 27521 and the isolation section 27522 are both arranged on the isolation cover 3, and the guide section 27521 is sleeved on the outside of the guide cover 2752; the guide section 27521, the isolation section 27522 and the isolation cover 3 form a collecting chamber, and the collecting chamber is used to collect the water flow sprayed from the nozzle 2751; the bottom of the guide section 27521 is provided with an outlet pipe 2753, and the outlet pipe 2753 is connected to the collecting chamber.

[0057] It should be noted that when the nozzle 2751 sprays cooling water, the cooling water carries the dust and impacts the guide cover 2752, so that the cooling water is stored in the collection chamber under the guidance of the guide section 27521 and the isolation section 27522, and then discharged through the outlet pipe 2753; in this way, the purpose of dust reduction during the feeding process is achieved, and at the same time, the sewage formed by the mixture of cooling water and dust is collected and treated to prevent secondary pollution.

[0058] like Figure 1-8 As shown, a rubber asphalt mixture feeding device includes a feeding mechanism.

[0059] It should be noted that asphalt is generally in the form of small pieces of gravel when used as a raw material. In order to facilitate transportation and mixing, it is generally a hard structure when used as a raw material. During the feeding process of the asphalt raw material, when the feeding height is large, the asphalt is easily broken by force, which affects the mixing work in the next step. Therefore, the control mechanism 25 and the adjustment mechanism 26 are set to control the feeding speed and height of the asphalt raw material, reduce the problem of breaking due to excessive impact force, reduce the generation of dust, and facilitate the mixing work in the next step.

[0060] At the same time, since the asphalt raw material will soften and its viscosity will increase sharply when the temperature rises, when the asphalt raw material feeding speed is controlled by the control mechanism 25, the conveying temperature will increase due to friction. Therefore, a cooling mechanism 27 is provided to achieve the cooling purpose and prevent the asphalt raw material from softening and increasing viscosity.
