Description

Technical Field

[0001] The utility model relates to the technical field of bucket elevators, and particularly relates to a quantitative discharging structure of a rubber granule elevator. Background Art

[0002] Modified asphalt is an asphalt binder made by doping modifiers such as rubber, resin, polymer, or other fillers to improve the performance of asphalt or asphalt mixture. Among them, solid modifiers are put into the mixing tank in the form of rubber granules for mixing. In the prior art, a bucket elevator is used to transport rubber granules from the ground to the top of the mixing tank through a through groove.

[0003] The bucket elevator mainly scoops up rubber granules from the following storage by the cyclic rotation of a number of hoppers fixedly connected to the traction chain or belt, lifts them to the top along with the traction chain or belt, and then turns downward after bypassing the top wheel, so that the rubber granules are thrown into the discharge pipe, thereby realizing the transportation of rubber granules in a vertical or nearly vertical direction. However, the bucket elevator does not have the function of quantitative discharging. Therefore, the rubber granules output from the discharge pipe need to be weighed before being put into the mixing tank; and in order to avoid long-distance transfer of the weighed rubber granules, a bucket elevator is correspondingly arranged for each mixing tank, resulting in low utilization rate of the elevator.

[0004] It can be seen that the prior art still needs to be improved. Summary of the Utility Model

[0005] In view of the deficiencies of the above prior art, the purpose of the present utility model is to provide a quantitative discharging structure of a rubber granule elevator, aiming to solve the technical problems of the elevator in the prior art being unable to quantitatively discharge and having low utilization rate.

[0006] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

A number of receiving bins are arranged on the peripheral wall of the rotating cylinder in a circumferential array; a recovery pipe and a number of feeding pipes are arranged below the distributing pipe, the recovery pipe and all the feeding pipes are arranged in a circumferential array, and the second rotating mechanism drives the distributing pipe to rotate so that the lower end of the distributing pipe corresponds to the upper end of the recovery pipe or any one of the feeding pipes.

[0008] Further, a flow dividing cover is arranged above the rotating cylinder, and the middle part of the flow dividing cover bulges upward.

[0009] Further, it further includes a stirring mechanism, the stirring mechanism includes a vertically slidable bracket, and a spring provided between the bracket and the shunt cover.

[0010] Further, a sliding sleeve is provided in the shunt cover. The upper end of the bracket is slidably connected to the sliding sleeve, and the spring is provided between the upper end of the bracket and the sliding sleeve.

[0011] Further, the blanking pipe includes a first blanking section, a material distribution section, and a second blanking section arranged in sequence from top to bottom. The inner wall of the material distribution section is matched with the outer wall of the rotating cylinder.

[0012] Further, the first rotating mechanism includes a first motor provided on the wall of the material distribution section, and a rotating shaft rotatably connected to the material distribution section.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 4 , the present utility model provides a quantitative discharging structure of a rubber particle elevator, including an elevator body 10, a discharging port 1 is provided on the elevator body 10, and the elevator body 10 can vertically lift rubber particles located at a low place to a high place. Among them, it also includes a blanking pipe 2 connected to the discharging port 1, a rotating drum 3 provided in the middle of the blanking pipe 2, a first rotating mechanism 4 for driving the rotating drum 3 to rotate, a material distribution pipe 5 rotatably connected to the lower end of the blanking pipe 2, and a second rotating mechanism 6 for driving the material distribution pipe 5 to rotate. A plurality of material receiving bins 31 arranged in a circumferential array are provided on the peripheral wall of the rotating drum 3; a recovery pipe 7 and a plurality of material conveying pipes 8 are provided below the material distribution pipe 5, and the recovery pipe 7 and all the material conveying pipes 8 are arranged in a circumferential array. The second rotating mechanism 6 drives the material distribution pipe 5 to rotate so that the lower end of the material distribution pipe 5 corresponds to the upper end of the recovery pipe 7 or any one of the material conveying pipes 8.

[0023] In actual use, the recovery pipe 7 is connected to a collection bucket to receive surplus materials; one material conveying pipe 8 corresponds to be connected to a mixing tank, so that the elevator body 10 can convey rubber particles to a plurality of mixing tanks, thereby improving the utilization rate of the elevator body 10.

[0024] When it is necessary to transport the rubber particles to the designated mixing tank, the second rotating mechanism 6 drives the material distribution pipe 5 to rotate, so that the lower end of the material distribution pipe 5 corresponds to the upper end of the material conveying pipe 8 connected to the mixing tank. The elevator body 10 is started to lift the rubber particles to the discharge port 1, and the rubber particles fall into the receiving bin 31 in the rotating cylinder 3 through the discharge port 1 and the blanking pipe 2. The first rotating mechanism 4 drives the rotating cylinder 3 to rotate. After the receiving bin 31 containing the rubber particles rotates 180°, the rubber particles automatically fall downward and fall into the mixing tank along the material distribution pipe 5 and the material conveying pipe 8. Since the rotating cylinder 3 rotates, the empty receiving bin 31 receives materials from the upper end of the blanking pipe 2 and then rotates 180°. The rubber particles in the receiving bin 31 automatically fall to the lower end of the blanking pipe 2. By making the weight of the rubber particles contained in each receiving bin 31 consistent and controlling the number of rotations of the rotating cylinder 3, the number of rubber particles passing through the blanking pipe 2 is controlled, thereby realizing the function of quantitative blanking.

[0025] In a preferred embodiment, referring to Figure 3 , a shunt cover 21 is provided above the rotating cylinder 3. The middle part of the shunt cover 21 bulges upward. Specifically, the discharge port 1 is of a funnel-shaped structure. The rubber particles shunted by the shunt cover 21 slide downward along the inner wall of the discharge port 1 to prevent the rubber particles from accumulating and failing to smoothly fall into the empty receiving bin 31.

[0026] In a preferred embodiment, referring to Figure 3 、 4 , it further includes a stirring mechanism 9. By providing the stirring mechanism 9, the movement of the rubber particles above the rotating cylinder 3 is further promoted to prevent the rubber particles from accumulating. The stirring mechanism 9 includes a vertically slidable support 91 and a spring 92 provided between the support 91 and the shunt cover 21. A plurality of horizontally extending stirring rods 93 are provided on the support 91. A turntable 32 is provided on the rotating cylinder 3. Specifically, the turntable 32 is located in the middle of the rotating cylinder 3 to divide each receiving bin 31 into two. The lower end of the support 91 abuts against the edge of the turntable 32, and a plurality of grooves 321 are formed in the edge of the turntable 32. The plurality of grooves 321 are arranged in a circumferential array. When the lower end of the support 91 abuts against the edge of the turntable 32, the spring 92 is compressed. The turntable 32 rotates with the rotating cylinder 3. When the groove 321 rotates to the lower end of the support 91, the spring 92 elongates due to the elastic force to drive the support 91 to move downward, so that the lower end of the support 91 abuts against the groove 321. Therefore, during the rotation of the rotating cylinder 3, the turntable 32 drives the support 91 to slide up and down, and further drives the stirring rods 93 to move up and down to promote the movement of the rubber particles.

[0027] Further, referring to Figure 4, a sliding sleeve 94 is provided inside the flow dividing cover 21. The upper end of the support 91 is slidably connected to the sliding sleeve 94, and a spring 92 is provided between the upper end of the support 91 and the sliding sleeve 94. Preferably, the support 91 includes a U-shaped frame 911 and a vertical rod 912 provided at the bottom of the U-shaped frame 911. The vertical rod 912 abuts against the edge of the turntable 32. There are two sliding sleeves 94, and the upper ends of both sides of the U-shaped frame 911 are respectively slidably connected to the two sliding sleeves 94. Stirring rods 93 are provided on both sides of the U-shaped frame 911. Through the above settings, the stirring range of the stirring mechanism 9 is increased, thereby ensuring that the rubber particles smoothly fall into the empty receiving bin 31.

[0028] In the above, the lower end of the vertical rod 912 is spherical, so that the vertical rod 912 slides along the edge of the turntable 32 to the groove 321 and slides from the groove 321 to the edge of the turntable 32.

[0029] In a preferred embodiment, the blanking pipe 2 includes a first blanking section 22, a material dividing section 23, and a second blanking section 24 arranged in sequence from top to bottom. The inner wall of the material dividing section 23 matches the outer wall of the rotating cylinder 3. As Figure 3 shown, when receiving materials, the empty receiving bin 31 faces the first blanking section 22, and the rubber particles fall into the receiving bin 31. Subsequently, the rotating cylinder 3 rotates by an angle, and a closed space is formed between the inner wall of the receiving bin 31 and the material dividing section 23 to prevent the rubber particles in the receiving bin 31 from falling. Finally, after the rotating cylinder 3 rotates by another angle, the receiving bin 31 faces the second blanking section 24, and the rubber particles fall downward due to their own weight. Therefore, the discharge amount of the second blanking section 24 can be controlled by controlling the rotation angle (or the number of rotation turns) of the rotating cylinder 3.

[0030] In the above, the length of the first blanking section 22 is the same as the length of the rotating cylinder 3 to fill the receiving bin 31 with rubber particles. The second blanking section 24 is of a funnel-shaped structure. The length of the upper end of the second blanking section 24 is the same as the length of the rotating cylinder 3 to enable the rubber particles in the receiving bin 31 to smoothly fall into the second blanking section 24. The lower end of the second blanking section 24 is cylindrical, so that the second blanking section 24 is rotatably connected to the material dividing pipe 5.

[0031] In a preferred embodiment, referring to Figure 4 , the first rotating mechanism 4 includes a first motor 41 provided on the wall of the material dividing section 23 and a rotating shaft 42 rotatably connected to the material dividing section 23. The first motor 41 drives the rotating shaft 42 to rotate, and the rotating cylinder 3 is provided on the rotating shaft 42. The first motor 41 drives the rotating shaft 42 to rotate, thereby driving the rotating cylinder 3 to rotate. Preferably, the first motor 41 is a servo motor. By controlling the rotation speed and the number of rotation turns of the first motor 41, it is convenient to control the number of rotation turns of the rotating cylinder 3, thereby realizing quantitative discharging.

[0032] In a preferred embodiment, referring to Figure 2 、 3, the second rotating mechanism 6 includes a gear ring 61 provided at the upper end of the material distribution pipe 5, a gear 62 meshing with the gear ring 61, and a second motor 63 for driving the gear 62 to rotate. Preferably, the second motor 63 is a stepper motor. The second motor 63 drives the gear 62 to rotate, and the gear 62 meshes with the gear ring 61 to drive the material distribution pipe 5 to rotate around the axis of the second blanking section 24. The material distribution pipe 5 corresponds to any one of the material conveying pipes 8, so that the rubber particles can be quantitatively put into the corresponding mixing tank. Through the above settings, it is realized that a hoist body 10 provides a certain amount of rubber particles for multiple mixing tanks, and the utilization rate of the hoist body 10 is high.

[0033] It should be understood that in order to ensure that the rubber particles fall into each mixing tank along the material conveying pipe 8, the material conveying pipe 8 should be inclined.

[0034] Furthermore, referring to Figure 2 , the material distribution pipe 5 includes a first vertical section 51, an inclined section 52, and a second vertical section 53 arranged in sequence from top to bottom. The outer diameter of the second vertical section 53 is smaller than the inner diameters of the recovery pipe 7 and the material conveying pipe 8. Through the above settings, it is realized that the rubber particles are drained from the blanking pipe 2 into the recovery pipe 7 or one of the material conveying pipes 8.

[0035] In practical applications, as Figure 2 shown, to ensure the stability of the installation of the recovery pipe 7, the material conveying pipes 8, and the material distribution pipe 5, an installation platform 20 is further included. The upper ends of the recovery pipe 7 and multiple material conveying pipes 8 are fixedly arranged on the installation platform 20. A support frame 201 is rotatably connected to the installation platform 20, and the support frame 201 is connected to the first vertical section 51.

[0036] In the above, the recovery pipe 7 is provided to drain the rubber particles into the recovery pipe 7, so that when repairing components such as the rotating drum 3, the rubber particles that have been lifted to the discharge port 1 can be recovered to prevent the rubber particles from falling into any mixing tank; in addition, the recovery pipe 7 is connected to a collection bucket to facilitate the unified collection of rubber particles and prevent the rubber particles from spilling onto the ground.

[0037] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solutions and the inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
