Description

Technical Field

[0001] This utility model relates to the technical field of waste rubber processing equipment, and in particular to a waste rubber crushing and discharge conveyor. Background Technology

[0002] With the rapid development of industries such as automobiles, the amount of waste rubber generated is increasing day by day. The treatment of waste rubber has become an important issue in the fields of environmental protection and resource recycling. In the process of waste rubber treatment, it needs to be crushed by crushing equipment, and the discharge conveyor is used to transport the crushed rubber from the discharge port of the crushing equipment to subsequent processing stages, such as screening, granulation, and storage.

[0003] Existing waste rubber crushing and discharge conveyors have some shortcomings. On the one hand, during the conveying process, due to the different sizes and irregular shapes of the waste rubber particles, material accumulation and blockage are likely to occur, affecting the conveying efficiency. On the other hand, during the conveying process, the dust contained in the waste rubber material is easy to escape, which not only pollutes the working environment but may also harm the health of the operators. Utility Model Content

[0004] The purpose of this utility model is to address the following shortcomings in the existing technology: existing waste rubber crushing and discharge conveyors are prone to material accumulation and blockage during the conveying process, and lack effective dust prevention measures, resulting in dust emission, which not only pollutes the working environment but may also harm the health of operators. Therefore, a waste rubber crushing and discharge conveyor is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A waste rubber crushing and discharge conveyor includes a platform, a conveying assembly on the upper surface of the platform, an installation cylinder above the conveying assembly, a feed bin connected to the top of the installation cylinder, a discharge channel connected to the bottom of the installation cylinder, a rotating rod horizontally rotatably mounted inside the installation cylinder, auger blades fixedly mounted on the surface of the rotating rod, and U-shaped rods fixedly mounted on both sides of the installation cylinder, with the bottom ends of the U-shaped rods fixedly connected to the surface of the platform. An L-shaped plate is fixedly installed at one end of the mounting cylinder, and a servo motor is fixedly installed on the surface of the L-shaped plate. One end of the rotating rod passes through the mounting cylinder and is fixedly connected to the output shaft of the servo motor. A water storage tank is fixedly installed on one side of the platform. Multiple mounting ports are symmetrically opened on the surface of the mounting cylinder. Spray nozzles are fixedly installed in the mounting ports. A water supply component is provided at one end of the spray nozzle. The water supply component is used to supply water located in the water storage tank to the spray nozzle.

[0006] Preferably, the water supply assembly includes an installation rod and an insertion rod. One end of the installation rod has a water groove, and the insertion rod is slidably and sealed inside the water groove. One end of the insertion rod is fixedly installed with a water outlet pipe, and the side wall of the insertion rod is fixedly installed with a water inlet pipe connected to a water storage tank. Multiple water outlet pipes are respectively fixedly connected to multiple nozzles. Both the water outlet pipe and the water inlet pipe are equipped with a one-way valve. The ends of multiple insertion rods located on one side of the installation cylinder are fixedly installed with fixing rods, and two fixing rods are controlled to move laterally reciprocatingly by a pressing component.

[0007] Preferably, the pressing component includes a sliding plate, two I-shaped blocks respectively fixedly installed at both ends of the sliding plate, and two inclined plates respectively fixedly installed at the ends of two fixed rods. The surface of the inclined plates is provided with sliding openings, and the two I-shaped blocks are slidably arranged in the two sliding openings. The surface of the rotating rod that protrudes from the mounting cylinder is provided with reciprocating threads, and the sliding plate is threadedly sleeved on the rotating rod.

[0008] Preferably, the one-way valve in the outlet pipe is directed from the water tank to the nozzle, and the one-way valve in the inlet pipe is directed from the water storage tank to the water tank.

[0009] Preferably, the conveying assembly includes two pairs of fixed plates fixedly mounted on the upper surface of the platform, two rotating shafts respectively horizontally rotatably mounted between the two pairs of fixed plates, two conveying rollers respectively fixedly sleeved on the two rotating shafts, and a conveyor belt wound on the two conveying rollers. A drive motor is fixedly mounted on the surface of one of the fixed plates, and the output shaft of the drive motor is fixedly connected to one of the rotating shafts.

[0010] Preferably, T-shaped baffles are symmetrically fixedly installed on the upper surface of the platform, and the sides of the two baffles that are close to each other slide in contact with the front and rear surfaces of the conveyor belt, respectively.

[0011] The beneficial effects of this utility model are as follows: By installing a rotating rod and auger blades inside the installation cylinder, waste rubber enters the installation cylinder from the discharge port of the crushing equipment through the feed hopper. Driven by the rotating rod, the auger blades allow the material to move along a specific direction in a relatively uniform and continuous manner to the surface of the conveying components, avoiding material accumulation. This pushing method can effectively handle waste rubber of different particle sizes and irregular shapes, preventing blockages caused by material squeezing and jamming. At the same time, during the rotation of the auger blades, the nozzles will intermittently spray water into the installation cylinder, which can effectively suppress the dust generated during the conveying of waste rubber, prevent dust from escaping into the working environment, protect the health of operators, and reduce dust pollution to the surrounding environment.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-4 A waste rubber crushing and discharge conveyor includes a platform 1, a conveying assembly on the upper surface of the platform 1, an installation cylinder 2 above the conveying assembly, a feed bin 3 connected to the top of the installation cylinder 2, a discharge channel 23 connected to the bottom of the installation cylinder 2, a rotating rod 4 horizontally rotatably installed inside the installation cylinder 2, an auger blade 5 fixedly installed on the surface of the rotating rod 4, and U-shaped rods 6 fixedly installed on both sides of the installation cylinder 2, with the bottom end of the U-shaped rods 6 fixedly connected to the surface of the platform 1.

[0016] An L-shaped plate is fixedly installed at one end of the mounting cylinder 2. A servo motor 7 is fixedly installed on the surface of the L-shaped plate. One end of the rotating rod 4 extends out of the mounting cylinder 2 and is fixedly connected to the output shaft of the servo motor 7. A water storage tank 8 is fixedly installed on one side of the platform 1. Multiple mounting ports are symmetrically opened on the surface of the mounting cylinder 2. Spray nozzles 9 are fixedly installed in the mounting ports. A water supply assembly is provided at one end of the spray nozzle 9. The water supply assembly is used to supply water located in the water storage tank 8 to the spray nozzle 9. The water supply assembly includes a mounting rod 10 and an insert rod 11. A water groove is opened at one end of the mounting rod 10. The insert rod 11 is slidably and sealed in the water groove. A water outlet pipe 12 is fixedly installed at one end of the insert rod 11. A water inlet pipe 13 connected to the water storage tank 8 is fixedly installed on the side wall of the insert rod 11. Multiple water outlet pipes 12 are fixedly connected to multiple spray nozzles 9 respectively. Both the outlet pipe 12 and the inlet pipe 13 are equipped with one-way valves. The one-way valve in the outlet pipe 12 is directed from the water tank to the nozzle 9, and the one-way valve in the inlet pipe 13 is directed from the water storage tank 8 to the water tank. The ends of multiple rods 11 located on one side of the mounting cylinder 2 are fixedly installed with fixing rods 14. The two fixing rods 14 are controlled to move laterally and reciprocally by a pressing component. The pressing component includes a sliding plate 15, two I-shaped blocks 16 fixedly installed at both ends of the sliding plate 15, and two inclined plates 17 fixedly installed at the ends of the two fixing rods 14. The surface of the inclined plate 17 is provided with a sliding opening 18. The two I-shaped blocks 16 are slidably arranged in the two sliding openings 18. The end of the rotating rod 4 that passes through the mounting cylinder 2 is provided with a reciprocating thread. The sliding plate 15 is threadedly sleeved on the rotating rod 4.

[0017] First, move the device to the crushing equipment and align the feed bin 3 with the discharge port of the crushing equipment. Then, feed the waste rubber into the crushing equipment for crushing. The crushed rubber will enter the feed bin 3 from the discharge port and then into the mounting cylinder 2. At the same time, start the servo motor 7. When the servo motor 7 starts, the rotating rod 4 will rotate accordingly, driving the auger blades 5 on the surface to rotate synchronously. During the rotation, the auger blades 5 will use their spiral structure to generate axial thrust on the material, pushing the rubber particles or blocky material along the axial direction of the mounting cylinder 2 to the discharge channel 23. Since the pitch, helix angle and other parameters of the auger blades 5 have been optimized, they can provide a uniform and stable pushing force according to the material characteristics, so that the material maintains an appropriate looseness during the conveying process and avoids blockage caused by compression or agglomeration. When the material reaches the discharge channel 23, it will fall directly onto the conveying component and be conveyed by the conveying component to the subsequent processing stage.

[0018] As the rotating rod 4 rotates, the reciprocating threads on its surface drive the sliding plate 15 to perform a lateral reciprocating motion. The I-shaped blocks 16 at both ends of the sliding plate 15 slide within the sliding opening 18 of the inclined plate 17, thereby converting the linear motion of the sliding plate 15 into the lateral pushing and pulling motion of the fixed rod 14. This causes the insertion rod 11 to reciprocate within the water tank. When the insertion rod 11 slides outward, the volume inside the water tank increases and the pressure decreases. Water located in the water storage tank 8 enters the water tank from the inlet pipe 13 under atmospheric pressure. When the insertion rod 11 slides inward, the volume inside the water tank decreases and the pressure increases. Water in the water tank is forced into the nozzle 9 from the outlet pipe 12. The water is sprayed out from multiple nozzles 9 symmetrically distributed on the surface of the mounting cylinder 2. The sprayed water mist can adhere to the rubber surface inside the mounting cylinder 2. The water mist combines with dust particles, increasing their weight and causing them to settle, effectively suppressing dust and achieving a dust prevention effect. At the same time, the water mist can also wet the rubber during the conveying process, reducing electrostatic adsorption caused by friction, further reducing dust generation. It can also clean the inner wall of the mounting cylinder 2 and the auger blades 5, reducing material residue and extending the service life of the equipment. The water spraying from the water tank 8 does not require an additional power source, reducing energy consumption and equipment costs.

[0019] The conveying assembly includes two pairs of fixed plates fixedly mounted on the upper surface of the platform 1, two rotating shafts respectively horizontally rotatably mounted between the two pairs of fixed plates, two conveyor rollers 19 respectively fixedly sleeved on the two rotating shafts, and a conveyor belt 20 wound on the two conveyor rollers 19. A drive motor 21 is fixedly mounted on the surface of one of the fixed plates, and the output shaft of the drive motor 21 is fixedly connected to one of the rotating shafts. T-shaped baffles 22 are symmetrically fixedly mounted on the upper surface of the platform 1, and the sides of the two baffles 22 that are close to each other slide in contact with the front and rear surfaces of the conveyor belt 20 respectively.

[0020] When the drive motor 21 is started, the output shaft of the drive motor 21 rotates with one of the rotating shafts, and both rotating shafts and the two conveyor rollers 19 will rotate together, so that the conveyor belt 20 will start to run.

[0021] The conveyor belt 20 is located below the discharge channel 23, and the upper surface of the conveyor belt 20 corresponds to the bottom opening of the discharge channel 23. The rubber falling from the discharge channel 23 will land on the surface of the conveyor belt 20. The operating conveyor belt 20 will transport the rubber to the subsequent processing stage. The two baffles 22 can prevent the material from falling off the conveyor belt 20.

[0022] In this invention, by setting a rotating rod 4 and an auger blade 5 inside the mounting cylinder 2, waste rubber enters the mounting cylinder 2 from the discharge port of the crushing equipment through the feed bin 3. Driven by the rotating rod 4, the auger blade 5 allows the material to move along a specific direction in a relatively uniform and continuous manner to the surface of the conveying component, avoiding material accumulation. This pushing method can effectively handle waste rubber with different particle sizes and irregular shapes, preventing blockages caused by mutual squeezing and jamming. At the same time, during the rotation of the auger blade 5, the nozzle 9 will intermittently spray water into the mounting cylinder 2, which can effectively suppress the dust generated during the conveying of waste rubber, prevent dust from escaping into the working environment, protect the health of operators, and reduce dust pollution to the surrounding environment.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
