Description

Technical Field

[0001] The utility model belongs to the technical field of non-metallic ore crushing, and in particular relates to a high-efficiency crushing device for composite material production. Background Art

[0002] Non-metallic ores refer to minerals that do not contain metal elements or contain very little metal elements. They are widely used in industry, construction, chemical industry, ceramics, glass manufacturing and other fields. During their processing and production, they need to be crushed.

[0003] Existing high-efficiency crushing devices for composite material production mostly use rotating crushing rollers to crush the mineral materials. Some also integrate multi-stage crushing structures such as coarse crushing mechanisms and fine crushing mechanisms into one device to achieve multi-stage crushing of ore raw materials and improve the ore crushing effect. However, this method not only requires the use of multiple driving devices, but also ore particles that have already met the fineness requirements will still be sent to the crushing process, which unnecessarily increases the workload of the crushing device and thus affects the efficiency of the crushing device. Utility Model Content

[0004] In view of this, the utility model provides a high-efficiency crushing device for composite material production, which can achieve the effect of generating multi-stage operations by one-stage drive through the driving component. It can only crush the mineral materials that do not meet the standards, effectively reduce the equipment load, and significantly improve the crushing efficiency.

[0005] The hopper is mounted on two opposite ends of the hopper and is used to move the hopper to the other ends of the hopper, and the hopper is mounted on two opposite ends of the hopper, wherein the hopper has a first end and a second end, and the hopper has a second end.

[0006] The elastic components include circular grooves respectively arranged on the upper surface of the guide plate, each of which is provided with a spring, and the upper ends of the springs are respectively fixedly connected to the top wall surface of the chute where they are located, thereby realizing elastic support for the screening bucket.

[0007] The driving assembly includes a rotating rod rotatably connected to the crushing box and located below the sub-screening bucket. Cams are provided at both ends of the rotating rod. A fixed block is provided near each cam at the lower end of the crushing box. The cams are respectively cooperated with the adjacent fixed blocks on the same side. The end of the cam away from the rotating rod is also provided with a rotating member for reducing the friction with the fixed block. That is, when the cam is away from one end of the rotating rod and contacts the fixed block, the fixed block and the sub-screening bucket overcome the spring force and move up along the guide plate. When the cam is away from one end of the rotating rod and separates from the fixed block, the fixed block and the sub-screening bucket are reset along the guide plate under the action of the spring rebound force. This process prompts the sub-screening bucket to achieve regular vibration screening during the rotation of the cam.

[0008] The rotating member includes rotating wheels which are respectively rotatably connected to the ends of the cams away from the rotating rods, thereby reducing the sliding friction between the cams and the fixed blocks and ensuring the efficient operation of the driving assembly.

[0009] The crushing mechanism includes crushing rollers that are symmetrically connected to the crushing box below the screening bucket. A gear is provided at the same end of the two crushing rollers, and the two gears are meshed with each other. A motor is provided at the end of the crushing box away from the gear. The motor is fixedly connected to the end of one crushing roller away from the gear. A transmission assembly is also provided at one end of one crushing roller, that is, the crushing roller connected to it and the gear on it are driven to rotate synchronously through the rotation of the motor output shaft. Since the two gears are meshed, the other crushing roller is driven to rotate synchronously in the opposite direction.

[0010] The transmission assembly includes a pulley 1 arranged at one end of a crushing roller, and a pulley 2 is provided at the end of the rotating rod close to the pulley 1. The pulley 2 is connected to the pulley 1 through a belt drive, thereby achieving the effect of generating multi-stage operation by one-stage drive.

[0011] A protective cover is provided at one end of the crushing box close to the gear, and the gear, pulley one and pulley two are all located in the protective cover, which protects the transmission components from interference from external impurities.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] When the motor starts, the motor output shaft rotates, driving the connected crushing roller and the gear on it to rotate synchronously. Since the two gears are meshed and connected, the other crushing roller is driven to rotate synchronously in the opposite direction. As the crushing roller rotates, the pulley set on it drives the pulley with a belt. The rotating rod and the cams at both ends of the rotating rod rotate synchronously. When the cam moves away from one end of the rotating rod and contacts the fixed block, the fixed block and the sub-screening bucket overcome the spring force and move up along the guide plate. When the cam moves away from one end of the rotating rod and separates from the fixed block, the fixed block and the sub-screening bucket are reset along the guide plate under the action of the spring rebound force. During this process, the sub-screening bucket realizes regular vibration screening during the rotation of the cam. Fine particles that meet the particle size requirements fall through the mesh of the sub-screening bucket and are discharged through the discharge port, while unqualified large particles continue to move along the sub-screening bucket and fall between the two rotating crushing rollers for crushing, realizing the effect of generating multi-stage operation by one-stage drive, which can only crush unqualified mineral materials, effectively reduce the load of the equipment, and significantly improve the crushing efficiency.

[0014] 2. The configuration of the rotating wheel reduces the sliding friction between the cam and the fixed block, ensuring the efficient operation of the drive assembly and maintaining the continuity and stability of the screening process. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0022] like Figure 1-5 As shown:

[0023] The present embodiment provides a high-efficiency crushing device for composite material production, comprising a crushing box 100 and a plurality of guide plates 101 respectively arranged at both ends of the inner cavity of the crushing box 100. The plurality of guide plates 101 at both ends of the inner cavity of the crushing box 100 are symmetrically distributed. A screening bucket 102 is slidably connected between the plurality of guide plates 101. The meshes of the screening bucket 102 are evenly distributed on the upper inclined surface thereof. The lower inclined surface of the screening bucket 102 is used to transmit fine particles of required particle size. Both ends of the screening bucket 102 are provided with a guide plate 101. 01 one-to-one corresponding chutes, the chutes are used to slide with the guide plates 101, one side of the crushing box 100 is provided with a discharge port 103 adapted to the sub-screening bucket 102, the discharge port 103 is used to discharge fine particles that meet the particle size requirements, and the crushing box 100 is provided with a crushing mechanism for crushing mineral materials below the sub-screening bucket 102, and multiple guide plates 101 are provided with elastic components for providing elastic support for the sub-screening bucket 102, and the crushing box 100 is also provided with a driving component for driving the sub-screening bucket 102 to move along the guide plate 101.

[0024] The mineral material is fed into the inner cavity of the crushing box 100 in an appropriate manner, and then the mineral material is screened by the regularly vibrating screening bucket 102. The fine particles that meet the particle size requirements fall through the mesh of the screening bucket 102 and are discharged through the discharge port 103, while the unqualified large particles continue to move along the screening bucket 102 and fall into the crushing mechanism for crushing, achieving the effect of generating multi-stage operations from one-stage drive, and can only crush the mineral materials that do not meet the standards, effectively reducing the equipment load and significantly improving the crushing efficiency.

[0025] like Figure 2-3 As shown, the elastic component includes circular grooves 104 respectively arranged on the upper surface of the guide plate 101, and springs 105 are provided in the circular grooves 104. The circular grooves 104 are used to provide fixed support for the springs 105. The upper ends of the springs 105 are fixedly connected to the top wall of the chute in which they are located. When the fixed block 108 and the sub-screening bucket 102 overcome the elastic force of the spring 105, they move upward along the guide plate 101. When the fixed block 108 and the sub-screening bucket 102 are reset, they are reset along the guide plate 101 under the action of the rebound force of the spring 105, thereby realizing elastic support for the sub-screening bucket 102.

[0026] like Figure 2-5As shown, the driving assembly includes a rotating rod 106 rotatably connected to the crushing box 100 located below the sub-screening bucket 102. The crushing box 100 is located below the sub-screening bucket 102 and is provided with a rotating hole 1 for providing rotation support for the rotating rod 106. Cams 107 are provided at both ends of the rotating rod 106. A fixed block 108 is provided near each cam 107 at the lower end of the crushing box 100. The cams 107 are respectively cooperated with the adjacent fixed blocks 108 on the same side. The cams 107 cooperate with the fixed blocks 108 to achieve regular up and down vibration of the sub-screening bucket 102. The end of the cam 107 away from the rotating rod 106 is also provided with a rotating member for reducing friction with the fixed block 108.

[0027] The rotating rod 106 and the cams 107 at both ends of the rotating rod 106 rotate synchronously. When the cam 107 is away from one end of the rotating rod 106 and contacts the fixed block 108, the fixed block 108 and the sub-screening bucket 102 overcome the elastic force of the spring 105 and move up along the guide plate 101. When the cam 107 is away from one end of the rotating rod 106 and separates from the fixed block 108, the fixed block 108 and the sub-screening bucket 102 are reset along the guide plate 101 under the action of the rebound force of the spring 105. This process prompts the sub-screening bucket 102 to achieve regular vibration screening during the rotation of the cam 107.

[0028] like Figure 2-4 As shown, the rotating member includes a rotating wheel 109 which is rotatably connected to the end of the cam 107 away from the rotating rod 106. The end of the cam 107 away from the rotating rod 106 is provided with a rotating groove for providing rotation support for the rotating wheel 109. The configuration of the rotating wheel 109 reduces the sliding friction between the cam 107 and the fixed block 108, thereby ensuring the efficient operation of the driving assembly and maintaining the continuity and stability of the screening process.

[0029] like Figure 2-5 As shown, the crushing mechanism includes a crushing roller 200 that is symmetrically connected to the crushing box 100 and is located below the screening bucket 102. A rotating hole 2 is provided in the crushing box 100 below the screening bucket 102 to provide rotation support for the crushing roller 200. The two crushing rollers 200 cooperate to achieve the crushing operation of unqualified large particles. The same end of the two crushing rollers 200 is provided with a gear 201, and the two gears 201 are meshed and connected to each other. When one gear 201 rotates, it drives the other gear 201 to rotate synchronously. A motor 202 is provided at the end of the crushing box 100 away from the gear 201. The motor 202 is fixedly connected to the end of a crushing roller 200 away from the gear 201. The output shaft of the motor 202 rotates to drive a crushing roller 200 and the gear 201 thereon to rotate synchronously. A transmission component is also provided at one end of a crushing roller 200.

[0030] The motor 202 is started, and the output shaft of the motor 202 rotates to drive the pulverizing roller 200 connected thereto and the gear 201 thereon to rotate synchronously. Since the two gears 201 are engaged with each other, the other pulverizing roller 200 is driven to rotate synchronously in the opposite direction.

[0031] like Figure 2-3 As shown, the transmission assembly includes a pulley 1 300 arranged at one end of a crushing roller 200, and a pulley 2 301 is provided at the end of the rotating rod 106 close to the pulley 1 300. The pulley 2 301 is connected to the pulley 1 300 through a belt transmission. As the crushing roller 200 rotates, the pulley 1 300 arranged thereon drives the pulley 2 301, the rotating rod 106 and the cams 107 at both ends of the rotating rod 106 to rotate synchronously with the belt, thereby achieving the effect of generating multi-stage operation by one-stage drive.

[0032] like Figure 1 As shown, a protective cover 400 is provided at one end of the crushing box 100 near the gear 201. The protective cover 400 is connected to the crushing box 100 by bolts to facilitate maintenance and repair of its internal structure. The gear 201, pulley 1 300 and pulley 2 301 are all located in the protective cover 400. The gear 201, pulley 1 300 and pulley 2 301 are all covered by the protective cover 400 to ensure the safety of the operator and protect the transmission components from interference from external impurities.

[0033] The working principle of a high-efficiency crushing device for composite material production provided by the present invention is as follows: first, the mineral material is fed into the inner cavity of the crushing box 100 in an appropriate manner, and then the motor 202 is started, and the output shaft of the motor 202 rotates to drive the crushing roller 200 connected thereto and the gear 201 thereon to rotate synchronously. Since the two gears 201 are meshed and connected, the other crushing roller 200 is driven to rotate synchronously in the opposite direction. As the crushing roller 200 rotates, the pulley 1 300 arranged thereon drives the pulley 2 301, the rotating rod 106 and the cams 107 at both ends of the rotating rod 106 to rotate synchronously. When the cam 107 moves away from one end of the rotating rod 106 and contacts the fixed block 108, the fixed block 108 and the sub-screening bucket 102 overcome the elastic force of the spring 105 and move up along the guide plate 101. When the cam 107 moves away from one end of the rotating rod 106 and separates from the fixed block 108, the fixed block 108 and the sub-screening bucket 102 are Under the action of the rebound force of the spring 105, it returns to its original position along the guide plate 101. During the rotation of the cam 107, the screening bucket 102 is prompted to achieve regular vibration screening. Fine particles that meet the particle size requirements fall through the mesh of the screening bucket 102 and are discharged through the discharge port 103, while unqualified large particles continue to move along the screening bucket 102 and fall between the two rotating crushing rollers 200 for crushing, achieving the effect of one-stage drive generating multi-stage operation. It can only crush unqualified mineral materials, effectively reduce the equipment load, and significantly improve the crushing efficiency. The configuration of the rotating wheel 109 reduces the sliding friction between the cam 107 and the fixed block 108, ensuring the efficient operation of the drive assembly and maintaining the continuity and stability of the screening process. The gear 201, pulley 1 300 and pulley 2 301 are all covered by the protective cover 400 to ensure the safety of the operator and protect the transmission components from interference from external impurities.
