Description

Technical Field

[0001] The present invention relates to the technical field of blanking devices, and more particularly to a blanking device for asphalt mixture production. Background Art

[0002] Asphalt mixture is the general term for mixtures formed by mixing mineral materials and asphalt mixtures. According to the material composition and structure, it is divided into continuous gradation and discontinuous gradation mixtures. According to the mineral aggregate gradation composition and void ratio, it is divided into dense gradation, semi-open gradation, and open gradation mixtures. According to the size of the nominal maximum particle size, it can be divided into extra-coarse, coarse, medium, fine, and sand-sized asphalt mixtures. According to the manufacturing process, it is divided into hot mix asphalt mixture, cold mix asphalt mixture, recycled asphalt mixture, etc.

[0015] 1. In the present invention, materials are input into the tank body, and after being mixed and stirred by the mixing component, asphalt mixture is formed. When it is necessary to discharge, the feed port of the discharge cylinder is aligned with the discharge port of the tank body. At this time, the asphalt mixture in the tank body will fall into the discharge cylinder.

The scraped asphalt will be discharged together with the asphalt mixture, or part of the asphalt that enters the sewage tank can be pushed out of the discharge by the movement of the scraping rod.

[0016] 2. Under the action of the knocking chain, when the amount of asphalt mixture in the tank body is discharged to a relatively small amount, the rotation motor can be controlled to increase the power, so that the rotation speed of the rotating column is increased. Subsequently, under the action of centrifugal force, the knocking chain will be driven to collide with the inner wall of the tank body, cleaning the residual asphalt mixture on the inner wall of the tank body. At the same time, while the rotating column rotates in the tank body, it slides back and forth, which can change the position of the knocking chain, and the knocking chain will swing, covering and knocking the inner wall area of the tank body. When the knocking chain contacts the residual asphalt mixture, it can take it away, and at the same time, the tank body will vibrate, causing the residual asphalt mixture to fall downward and be discharged, preventing the inner wall of the tank body from having residual asphalt mixture, realizing the cleaning of the asphalt mixture in the tank body, and enabling it to be completely discharged and fed.

Detailed implementation manners

[0032] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples, and a blanking device for asphalt mixture production according to the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0033] As Figure 1-14 shown, in one embodiment, a blanking device for asphalt mixture production is proposed, which includes a machine base 1. A support frame 101 is installed at the upper end of the machine base 1. A tank body 2 is installed at the upper end of the support frame 101. An input port 201 is installed on the tank body 2. A discharge port 202 is installed at the lower end of the tank body 2. A mixing assembly 3 is arranged inside the tank body 2. The mixing assembly 3 includes a stirring mechanism 31 and a knocking mechanism 32. The stirring mechanism 31 is used for stirring the asphalt mixture inside the tank body 2, and the knocking mechanism 32 is used for knocking the inner wall of the tank body 2. A support seat 203 is installed on the circumferential surface of the tank body 2. A blanking assembly 4 is arranged inside the support seat 203. The blanking assembly 4 includes a discharging mechanism 41 and a cleaning mechanism 42. The discharging mechanism 41 includes a discharge cylinder 411, a connecting rod 412, a screw blade 413 and a driving motor 415. The discharge cylinder 411 is rotatably connected inside the support seat 203. The discharge cylinder 411 is slidably connected to the tank body 2. The connecting rod 412 is rotatably connected inside the discharge cylinder 411. The screw blade 413 is installed on the circumferential surface of the connecting rod 412. An installation seat 414 is installed at the upper end of the machine base 1. The output end of the driving motor 415 installed inside the installation seat 414 is connected to the connecting rod 412;

[0034] The cleaning mechanism 42 includes a connecting roller 421, a belt 422 and a scraping rod 423. A pair of connecting rollers 421 are rotatably connected inside the discharge cylinder 411 through a rotating shaft. The belt 422 is connected between the connecting rollers 421. A plurality of scraping rods 423 are equidistantly installed on the surface of the belt 422. A sewage discharge groove 424 is formed on the inner wall of the discharge cylinder 411. The scraping rod 423 is slidably connected to the sewage discharge groove 424 and the screw blade 413.

[0035] In practical applications of the embodiments of the present invention, materials are input into the tank body 2, and then mixed and stirred by the mixing assembly 3 to form asphalt mixture. When discharging is required, the discharge cylinder 411 is rotated 180 degrees to make the feed port of the discharge cylinder 411 correspond to the discharge port 202 of the tank body 2. At this time, the asphalt mixture in the tank body 2 will fall into the discharge cylinder 411. Subsequently, by controlling the operation of the driving motor 415, the connecting rod 412 is driven to rotate, and then the auger blade 413 rotates. At the same time, under the action of the agitating mechanism 31, the asphalt mixture in the tank body 2 is agitated to assist the asphalt mixture to fall into the discharge cylinder 411. Subsequently, the asphalt mixture will be conveyed outward by the auger blade 413 to complete the feeding of the asphalt mixture. By the feeding method of the auger blade 413, the feeding amount can be controlled. For example, Figures 11-14 As shown, due to the feeding characteristics of the auger blade 413, there is a certain limiting effect on the amount of discharged materials during the transportation and discharge of materials. The amount of the mixture pushed per revolution is basically the same, and there will be no situation of excessive discharge at one time. And the auger blade 413 is driven by the driving motor 415. By setting an encoder, the feeding amount can be controlled according to the rotation speed and rotation time of the driving motor 415, so that the discharge amount can be controlled. At the same time, during the process of pushing and feeding by the auger blade 413, part of the asphalt in the asphalt mixture will adhere to the inner wall of the discharge cylinder 411, and the auger blade 413 will scrape off the residual asphalt on the inner wall of the discharge cylinder 411 and accumulate on the auger blade 413. If not cleaned in time, it will affect the normal operation of the auger blade 413. At this time, under the action of the scraping rod 423, the connecting roller 421 and the belt 422, since the scraping rod 423 moves linearly and the auger blade 413 moves in a circular helix, the scraping rod 423 will be pushed forward during the rotation of the auger blade 413. After the scraping rod 423 moves forward, it will drive the belt 423 to rotate, driving the scraping rod 423 to move in a cycle, so that a sliding occurs between the scraping rod 423 and the auger blade 413. When a sliding occurs between the scraping rod 423 and the auger blade 413, the asphalt mixture adhered to the surface of the auger blade 413 can be scraped off, avoiding the accumulation of the asphalt mixture on the surface of the auger blade 413, thus achieving the effect of preventing the asphalt mixture from adhering to the auger blade 413. And the scraped asphalt will be discharged together with the asphalt mixture, or part of the asphalt that enters the sewage tank 424 can be pushed out of the discharge by the movement of the scraping rod 423.

[0036] In one case of the embodiment of the present invention, although the auger blade 413 has a good control effect on the material feeding amount, if the asphalt adhered to the auger blade 413 is not cleaned in time, after excessive accumulation and cooling, the friction between the auger blade 413 and the discharge cylinder 411 will increase, thereby increasing the resistance when the auger blade 413 rotates, increasing the working burden of the driving motor 415, and being unfavorable for the normal use of the equipment.

[0037] As Figure 3 and 11 shown, as a preferred embodiment of the present invention, a gear 5 is installed on the circumferential surface at the rear end of the discharge cylinder 411, a hydraulic cylinder 501 is installed in the machine base 1, and a rack 502 engaged with the gear 5 is installed at the output end of the hydraulic cylinder 501.

[0038] In the actual application of the embodiment of the present invention, by controlling the operation of the hydraulic cylinder 501, the rack 502 can be driven to move up and down, and then the gear 5 can be driven to rotate, so as to control the rotation direction of the discharge cylinder 411, and make the discharge cylinder 411 show the state of blocking the tank body 2 and the state of opening the discharge.

[0039] In one case of the embodiment of the present invention, when the feed port of the discharge cylinder 411 faces downward, it is in the state of blocking the tank body 2 at this time. When the feed port of the discharge cylinder 411 faces upward, it is in the state of opening the discharge at this time. Since the discharge cylinder can block a large area of the tank body 2, the opening area of the discharge port 202 of the tank body 2 can be increased to the maximum, making the discharge during material feeding smoother.

[0040] As Figure 3 and 11 shown, as another preferred embodiment of the present invention, a mounting bracket 503 is installed at the upper end of the machine base 1, a limiting bracket 504 is installed at the front end of the mounting bracket 503, and the limiting bracket 504 is slidably connected to the rack 502.

[0041] In the actual application of the embodiment of the present invention, under the action of the limiting bracket 504, the limiting bracket 504 slides with the rack 502, which plays a role in limiting the movement of the rack 502 and improves the stability of the movement of the rack 502.

[0042] As Figure 8 and 10As shown, as another preferred embodiment of the present invention, the stirring mechanism 31 includes a rotating column 311, stirring rods 312, a rotating motor 313, and a driving rod 314. The rotating column 311 is rotatably connected inside the tank body 2. A plurality of stirring rods 312 are all installed inside the rotating column 311. The rotating motor 313 is installed on the mounting seat 414. The driving rod 314 is connected to the output end of the rotating motor 313. The driving rod 314 is slidably connected to the rotating column 311. A limiting block 315 is installed on the circumferential surface of the driving rod 314. A limiting groove 316 is formed on the inner wall of the rotating column 311. The limiting block 315 and the limiting groove 316 cooperate with each other.

[0043] In the actual application of the embodiment of the present invention, by controlling the operation of the rotating motor 313, the driving rod 314 is driven to rotate. Through the cooperation of the limiting block 315 and the limiting groove 316, the rotating column 311 can be driven to rotate, and then the stirring rods 312 are driven to rotate, so as to realize the stirring and mixing of the materials in the tank body 2. At the same time, when discharging materials, it can also play the role of stirring the materials to facilitate their falling. During the stirring process, by controlling the sliding of the rotating column 311 on the circumferential surface of the driving shaft, the stirring rods 312 are driven to slide back and forth. While the stirring rods 312 stir the materials, they move back and forth, increasing the stirring coverage area and making the material stirring more uniform.

[0044] As Figure 8 and 10 shown, as another preferred embodiment of the present invention, a sliding rod 317 is fixedly connected between the mounting seat 414 and the tank body 2. A reciprocating lead screw 318 is rotatably connected between the mounting seat 414 and the tank body 2. A driving block 319 is slidably connected to the circumferential surface of the sliding rod 317. The driving block 319 is threadedly connected to the reciprocating lead screw 318. A driving disk 3110 is installed at the rear end of the rotating column 311. The driving disk 3110 is located inside the driving block 319 and is rotatably connected to the driving disk 3110.

[0045] In the actual application of the embodiment of the present invention, by controlling the rotation of the reciprocating lead screw 318 and under the guiding action of the sliding rod 317 on the driving block 319, the driving block 319 can be driven to move back and forth, and then the driving disk 3110 is driven to move back and forth, so as to achieve the effect of controlling the rotation of the rotating column 311 in the tank body 2 while performing back and forth sliding.

[0046] In one case of the embodiment of the present invention, as Figure 10As shown in the figure, the limiting block 315 in the figure plays a role in driving the rotation of the rotating column 311 when the driving rod 314 rotates. Without the cooperation of the limiting block 315 and the limiting groove 316, the rotating column 311 will not rotate when the driving rod 314 rotates. When the driving rod 314 rotates, the rotating column 311 can be driven to rotate under the action of the limiting block 315. At the same time, when the driving block 319 moves back and forth, it can drive the rotating column 311 to move back and forth in cooperation with the driving disc 3110, so as to realize the effect of moving back and forth during the rotation of the rotating column 311; when the rotating column 311 rotates and moves back and forth at the same time, as Figure 8 shown, it can drive the stirring rod 312 and the knocking chain 322 to move back and forth at the same time during the rotation. In this case, not only can the stirring effect of the mixture in the tank body be improved, but when the mixture in the tank body is emptied, due to the back-and-forth movement of the knocking chain during rotation, the inner wall of the tank body can be knocked without dead ends, so that the mixture adhering to the inner wall of the tank body can be knocked off and dropped, making the discharge of the mixture complete and avoiding part of the mixture adhering to the inner wall of the tank body and causing it to be unable to be discharged.

[0047] As Figure 10 shown, as another preferred embodiment of the present invention, a first sprocket 3111 is installed on the circumferential surface of the driving rod 314, and a second sprocket 3112 is installed on the circumferential surface of the reciprocating lead screw 318. The first sprocket 3111 and the second sprocket 3112 are connected by a chain.

[0048] In the actual application of the embodiment of the present invention, when the rotating motor 313 drives the driving rod 314 to rotate, the rotating motor 313 will drive the first sprocket 3111 to rotate. Subsequently, under the action of the chain and the second sprocket 3112, the reciprocating lead screw 318 will be driven to rotate, so as to achieve the effect of controlling the reciprocating sliding of the rotating column 311 in the tank body 2.

[0049] As Figure 8 and 9 shown, as another preferred embodiment of the present invention, the knocking mechanism 32 includes a connecting buckle 321 and a knocking chain 322. The connecting buckle 321 is installed on the surface of the stirring rod 312, and the knocking chain 322 is installed in the connecting buckle 321. The knocking chain 322 is connected by a plurality of loop buckles.

[0050] In practical application of the embodiment of the present invention, when the amount of asphalt mixture in the tank body 2 is discharged to a relatively small amount, the rotation motor 313 can be controlled to increase the power, so that the rotation speed of the rotating column 311 is increased. Subsequently, under the action of centrifugal force, the knocking chain 322 will be driven to collide with the inner wall of the tank body 2, and the residual asphalt mixture on the inner wall of the tank body 2 will be cleaned. At the same time, while the rotating column 311 rotates in the tank body 2, it slides back and forth, which can change the position of the knocking chain 322, and the knocking chain 322 will swing, so as to cover and knock the inner wall area of the tank body 2. When the knocking chain 322 contacts the residual asphalt mixture, it can take it away, and at the same time, the tank body 2 can be vibrated, so that the residual asphalt mixture falls downward and is discharged, avoiding the residual asphalt mixture on the inner wall of the tank body 2, realizing the cleaning of the asphalt mixture in the tank body 2, and enabling it to be completely discharged for feeding.

[0051] As Figures 4-6 shown, as another preferred embodiment of the present invention, a plurality of heating tubes 6 are installed in the tank body 2, and a heat insulation cover 601 is installed on the outer surface of the tank body 2.

[0052] In practical application of the embodiment of the present invention, when loading the asphalt mixture in the tank body 2, under the action of the heating tube 6, the tank body 2 can be maintained at a certain temperature to avoid asphalt solidification, so that the asphalt mixture can maintain a good mixing state.
