DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0040] As shown in Figures 1-8 , a feeding mechanism, as shown in Figures 1-2 , and Figure 5As shown, the device comprises a collecting hopper 1; a material guiding mechanism 2 is arranged on the collecting hopper 1; the material guiding mechanism 2 comprises a first mounting frame 21, which is mounted on the collecting hopper 1; a lower hopper 22, which is mounted on the first mounting frame 21; a material guiding cylinder 23, which is arranged on the first mounting frame 21, and one end of the material guiding cylinder 23 is inclined downward and extends into the collecting hopper 1; a connecting hose 24, which is arranged between the lower hopper 22 and the material guiding cylinder 23, and the bottom of the lower hopper 22 is communicated with the inside of the material guiding cylinder 23 through the connecting hose 24; it can be understood that the connecting hose 24 is a bellows structure, so that when the connecting hose 24 is bent under stress, the inner diameter thereof can remain unchanged to allow the material to pass through; a control mechanism 25, which is arranged on the material guiding cylinder 23; the material guiding cylinder 23 is used to control the discharging speed of the material in the material guiding cylinder 23; and an adjusting mechanism 26, which is arranged between the first mounting frame 21 and the material guiding cylinder 23; the adjusting mechanism 26 is used to control the relative position of the discharging end of the material guiding cylinder 23 in the collecting hopper 1.

[0041] It should be noted that when in use, the material is introduced into the lower hopper 22, so that the material is introduced into the material guiding cylinder 23 through the connecting hose 24; since the material guiding cylinder 23 is inclined downward and inserted into the collecting hopper 1, under the action of gravity, the material is introduced into the collecting hopper 1 along the material guiding cylinder 23; by arranging the material guiding cylinder 23 to be inclined, the initial speed of the material introduced into the collecting hopper 1 can be reduced, 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 further reducing the influence on the next material mixing work;

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

[0043] During the process of introducing the material into the collecting hopper 1 through the material guiding cylinder 23, as the material accumulates in the collecting hopper 1, the adjusting mechanism 26 is used to drive the material guiding cylinder 23 to rotate, so as to drive the discharging end of the material guiding cylinder 23 to move upward, so that the material feeding speed is not affected, and the accumulation of the material in the collecting hopper 1 does not affect the discharging of the material in the material guiding cylinder 23, that is, the distance between the discharging end of the material guiding cylinder 23 and the height of the material accumulation is controlled.

[0044] As shown in Figures 1-2 and Figure 5 the control mechanism 25 comprises a spiral blade 251 coaxially connected in the material guiding cylinder 23 and a motor 252 mounted on the material guiding cylinder 23; the output end of the motor 252 is coaxially connected with the spiral blade 251.

[0045] It should be noted that the purpose of controlling the conveying speed of the material in the guide cylinder 23 is achieved by driving the helical blade 251 to rotate by the motor 252; specifically, when the downward inclination angle of the guide cylinder 23 is large, i.e. in the initial feeding stage, the helical blade 251 can be driven to rotate reversely by the motor 252, so that the helical blade 251 forms an upward thrust on the material; at this time, since the downward inclination angle of the guide cylinder 23 is large, the component of the gravity of the material on the axis of the guide cylinder 23 is large, so that the material is conveyed in the guide cylinder 23 at a relatively fast speed, and therefore, by driving the helical blade 251 to rotate reversely, a thrust on the material towards the inlet end of the guide cylinder 23 is formed to offset a part of the component of the gravity of the material on the axis of the guide cylinder 23, so as to achieve the purpose of slowing down the conveying speed of the material in the guide cylinder 23;

[0046] With the outlet end of the guide cylinder 23 being continuously rotated upwards by the adjusting mechanism 26, the downward inclination angle of the guide cylinder 23 is continuously reduced, and at this time, the rotation speed of the helical blade 251 can be slowed down by the motor 252 to ensure that the material has a suitable conveying speed in the guide cylinder 23, so as to prevent the material from being discharged too fast while ensuring the feeding efficiency; with the guide cylinder 23 being further rotated upwards by the adjusting mechanism 26, the component of the gravity of the material on the axis of the guide cylinder 23 is too small, i.e. the conveying speed of the material in the guide cylinder 23 is too slow, and at this time, the helical blade 251 can be driven to rotate forward by the motor 252 to form a thrust on the material towards the outlet end of the guide cylinder 23, so as to provide assistance for the material to be discharged from the guide cylinder 23, and thus the discharging efficiency of the material is increased.

[0047] As shown in Figures 1-3 and Figure 6 , the adjusting mechanism 26 comprises a rotating shaft 261 and a cylinder 263; the rotating shaft 261 is arranged on the guide cylinder 23, and the axis of the rotating shaft 261 is perpendicular to the axis of the guide cylinder 23; the cylinder 263 is arranged between the collecting hopper 1 and the rotating shaft 261, and a sliding groove 262 is formed on the first mounting frame 21; the cylinder 263 has an arc-shaped structure; the rotating shaft 261 is slidingly connected to the sliding groove 262, and one end of the rotating shaft 261 penetrates through the sliding groove 262 and is rotationally 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 adjusting mechanism 26 further comprises 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 sliding groove 262, the gear 264 can drive the rack 265 to engage.

[0048] It should be noted that the material is accumulated in the collecting hopper 1, and as the material accumulation height approaches the discharge end of the guide chute 23, the rotation of the guide chute 23 is controlled by the adjusting mechanism 26, so that the discharge end of the guide chute 23 always maintains a certain distance from the material accumulation height, which will not cause the material to collapse due to a large drop, and will not affect the material discharge due to a too close distance. Specifically, the rotating shaft 261 is moved by the cylinder 263 to slide in the sliding groove 262, thereby driving the guide chute 23 to move along the arc-shaped track of the sliding groove 262, so that the discharge end of the guide chute 23 moves obliquely upward from the center position of the collecting hopper 1 to the outside of the collecting hopper 1, thereby maintaining a certain distance between the discharge end of the guide chute 23 and the material accumulation height in the collecting hopper 1, while moving the discharge end of the guide chute 23 from the center position of the collecting hopper 1 to the outside, so that the material accumulated in the collecting hopper 1 is relatively flat;

[0049] As the cylinder 263 continues to move the rotating shaft 261, the gear 264 engages with the rack 265, and at this time, as the rotating shaft 261 continues to move, the gear 264 is driven to rotate under the limitation of the rack 265, thereby driving the guide chute 23 to rotate upward. That is, in this process, the guide chute 23 moves upward while the discharge end of the guide chute 23 rotates upward, and at this time, the discharge end of the guide chute 23 moves from the position close to the inner wall of the collecting hopper 1 to the center position of the collecting hopper 1, so that during the feeding process in the collecting hopper 1, the top of the material can be ensured to be relatively flat, thereby improving the space utilization and reducing the influence of the material accumulated in the collecting hopper 1 on the material discharge in the guide chute 23.

[0050] As shown in Figures 1-4 The collecting hopper 1 is provided with a isolation cover 3, and the isolation cover 3 is provided with a staggered hole 266, and one end of the guide chute 23 is inserted into the collecting hopper 1 through the staggered hole 266; the staggered hole 266 is covered with an elastic cloth 267, and the elastic cloth 267 is connected with the guide chute 23; the elastic cloth 267 is used to block the staggered hole 266 to isolate the inside and outside of the collecting hopper 1.

[0051] It should be noted that during the feeding process, as the material is discharged, dust pollution is easy to occur, therefore, the isolation cover 3 and the elastic cloth 267 structure are provided to realize the normal movement of the guide chute 23 while forming a relative isolation state between the collecting hopper 1 and the outside environment, thereby reducing dust flying.

[0052] As shown in Figures 2-4 and Figures 7-8As shown, the material guiding mechanism 2 further comprises a temperature reducing mechanism 27, which is arranged on the material guiding cylinder 23. The temperature reducing mechanism 27 is used to reduce the working temperature of the control mechanism 25. The temperature reducing mechanism 27 comprises a cooling pipe 271, a second mounting frame 272, a water inlet pipe 273 and a water outlet pipe 274. The cooling pipe 271 is sleeved on the material guiding cylinder 23. The top of the isolation cover 3 is provided with a through hole. The second mounting frame 272 is mounted on the through hole. The water inlet pipe 273 and the water outlet pipe 274 are arranged on the second mounting frame 272. One end of the cooling pipe 271 is connected with the water inlet pipe 273. The other end of the cooling pipe 271 is connected with the water outlet pipe 274. The water inlet pipe 273 comprises a straight pipe and a first spring hose. The straight pipe is arranged on the second mounting frame 272 and is used to be connected with the outside. The first spring hose is arranged between the cooling pipe 271 and the second mounting frame 272. The water outlet pipe 274 is a second spring hose structure.

[0053] It should be noted that, in the process of conveying the material by rotating the spiral blade 251, the spiral blade 251 and the material guiding cylinder 23 will rub against each other, which will increase the temperature. Some materials will be affected by the temperature, which will increase the viscosity of the materials, and thus affect the conveying of the materials. Therefore, the temperature reducing mechanism 27 is arranged to reduce the temperature and reduce the influence caused by the increase of the temperature during the conveying of the materials. Specifically, the cooling pipe 271 is arranged around the outside of the material guiding cylinder 23. The cooling pipe 271 is an S-shaped curved structure around the outer wall of the material guiding cylinder 23. When the 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 guiding cylinder 23, and improves the temperature reducing effect. It can be understood that, by arranging the spring hose structures of the water inlet pipe 273 and the water outlet pipe 274, the temperature reducing effect on the material guiding cylinder 23 can be ensured under the movement state of the material guiding cylinder 23.

[0054] As shown in Figs. Figures 2-4 and Figures 7-8 The temperature reducing mechanism 27 further comprises a dust reducing mechanism 275. The dust reducing mechanism 275 comprises a spray head 2751 and a flow guide cover 2752. The spray head 2751 is arranged on the second mounting frame 272. One end of the water outlet pipe 274 is connected with the second mounting frame 272. The flow guide cover 2752 is arranged on the through hole of the isolation cover 3. The flow guide cover 2752 is used to collect the water flow sprayed by the spray head 2751.

[0055] It should be noted that, due to the need to set the air outlet at the top of the collecting hopper 1 during the feeding process, in order to reduce the influence of air pressure on the material introduction, but the setting of the air outlet will cause the dust to fly from the air outlet to the outside, causing dust pollution, so the dust falling mechanism 275 is used in combination with the cooling mechanism 27, and the cooling water is sprayed to the air outlet position, realizing the purpose of dust falling; Specifically, the cooling water discharged through the water outlet pipe 274 is sprayed through the spray head 2751, the sprayed cooling water is inverted in the umbrella-shaped structure, forming a conical water curtain shielding the air outlet position, and is collected by the flow guide cover 2752; When the dust flies from the air outlet, the cooling water sprayed by the spray head 2751 contacts the dust and is collected by the flow guide cover 2752, so that the dust falling purpose is realized by using the water after cooling.

[0056] As shown in Figure 4 The flow guide cover 2752 is an open-top structure; the flow guide cover 2752 includes a flow guide section 27521 and an isolation section 27522; the flow guide section 27521 and the isolation section 27522 are arranged in the isolation cover 3, and the flow guide section 27521 is arranged outside the flow guide cover 2752; The flow guide section 27521, the isolation section 27522 and the isolation cover 3 form a collection cavity, which is used to collect the water flow sprayed by the spray head 2751; The bottom of the flow guide section 27521 is provided with a discharge pipe 2753, which is in communication with the collection cavity.

[0057] It should be noted that when the spray head 2751 sprays cooling water, the cooling water carries dust to impact the flow guide cover 2752, so that the cooling water is stored in the collection cavity under the guidance of the flow guide section 27521 and the isolation section 27522, and then is discharged through the discharge pipe 2753; Thus, the dust falling purpose during the feeding process is realized, and the sewage formed by the mixture of cooling water and dust is collected and treated to prevent secondary pollution.

[0058] As shown in Figures 1-8 A rubber asphalt mixture feeding device, comprising a feeding mechanism.

[0059] It should be noted that the asphalt as raw material is generally in the form of small stones, and is generally in a hard structure as raw material to facilitate conveying and mixing. During the feeding process of the asphalt raw material, when the feeding drop is large, the asphalt is easy to be broken under stress, which affects the next mixing work. Therefore, the control mechanism 25 and the adjusting mechanism 26 are arranged to control the feeding speed and drop of the asphalt raw material, reduce the problem of excessive impact force and breakage, reduce the generation of dust, and facilitate the next mixing work.

[0060] At the same time, since the asphalt raw material will soften and the viscosity will increase sharply when the temperature increases, when the asphalt raw material feeding speed is controlled by the control mechanism 25, the conveying temperature will increase due to friction, so the cooling mechanism 27 is arranged to achieve the purpose of cooling, preventing the problem of softening and viscosity increase of the asphalt raw material.
