Description

Technical Field

[0001] This utility model relates to the technical field of crushers, specifically a metallurgical material crusher. Background Technology

[0002] Powder metallurgy is an important new material preparation technology that produces various composite materials by mixing and pressing various metal and non-metal powders. It has wide applications in aerospace, nuclear industry, and medical fields. However, the development of powder metallurgy materials requires the raw materials to be pulverized for subsequent processing.

[0003] However, traditional crushers can only crush materials once, resulting in uneven particle size and inconsistent powder specifications, which affects the processing quality. Utility Model Content

[0004] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes a metallurgical material crusher, comprising: Box; There is a pair of crushing rollers, both of which are rotatably installed inside the housing for crushing materials; A pair of annular components are rotatably mounted on the two side walls inside the housing. A pair of conveying shovels are fixedly installed between the pair of ring-shaped parts to convey the material on the lower end face of the box back to the pair of crushing rollers. A drive mechanism, located on the housing, is used to drive one of the ring-shaped components to rotate.

[0005] Preferably, the drive mechanism includes; The first drive motor is fixedly installed on the outer wall of the housing, and its output end passes through one side wall of the housing; The first gear is fixedly mounted on the output end of the first drive motor; An external gear ring is fixedly mounted on one of the ring-shaped components and meshes with the first gear.

[0006] Preferably, a pair of second gears are provided on one side of the housing, and the pair of second gears are fixedly connected to one end of the pair of crushing rollers, and the pair of second gears are meshed together. A second drive motor is fixedly installed on the outer wall of the box, and the output end of the second drive motor is fixedly connected to one end of one of the crushing rollers.

[0007] Preferably, the lower wall of the box body has a discharge port, and a baffle for sealing the discharge port is hinged to the lower wall of the box body; A fixing block is fixedly installed on the lower wall of the box. A sliding hole is formed on the fixing block. A sliding pin for locking the baffle in the discharge port is slidably installed in the sliding hole. A spring is sleeved on the outer surface of the sliding pin. The two ends of the spring are fixedly connected to the inner wall of the sliding hole and the outer surface of the sliding pin, respectively.

[0008] Preferably, the upper wall of the box is provided with a feeding hopper.

[0009] The beneficial technical effects of this utility model are as follows: Achieving cyclic crushing significantly improves particle size uniformity: By setting rotatable annular components on both sides of the box and fixing a conveying shovel between the annular components, and driving the annular components to rotate in conjunction with the drive mechanism, the material that has been crushed once at the bottom of the box can be continuously scooped up and re-conveyed between a pair of crushing rollers for further crushing. This design fundamentally solves the key problem of "uneven material particle size and inconsistent powder specifications" caused by "traditional crushers can only crush once" in the background technology, ensuring the consistency of particle size of the final crushed product and greatly improving the processing quality of powder metallurgy raw materials.

[0010] 2. The drive structure is stable, reliable, and rationally laid out: The ring drive adopts a structure of a first drive motor, gears and an external gear ring, which ensures direct power transmission and stable meshing, thus ensuring the reliability of the conveyor shovel's cyclic operation. The crushing roller drive uses a second drive motor to drive one crushing roller, and drives the other crushing roller to rotate in the opposite direction through a pair of meshing second gears. It has a compact structure, high transmission efficiency, and ensures that the crushing rollers work synchronously and effectively. The crushing roller drive and the conveyor shovel drive are designed separately, with clear functions, no interference between them, and stable operation.

[0011] 3. The sealing and opening / closing operation of the discharge port is convenient and reliable: The discharge port baffle is installed by hinge and is designed with a locking mechanism consisting of a sliding pin, a spring, and a fixed block with a sliding hole. The spring force keeps the sliding pin in a locked state, ensuring that the baffle is tightly sealed and preventing material leakage. When material needs to be discharged, the baffle can be unlocked by sliding the sliding pin against the spring force. The operation is simple and quick. This structure effectively ensures the sealing of the equipment during operation and simplifies the discharge control operation. Attached Figure Description

[0019] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] This utility model proposes a material crusher for metallurgy, comprising: Box 1; Crushing rollers 2, in pairs, are rotatably installed inside housing 1 and are used to crush materials; Annular parts 3, in pairs, are rotatably mounted on the two side walls inside the housing 1; The conveying shovels 4, in pairs, are fixedly installed between a pair of annular parts 3, and are used to re-convey the material on the lower end face inside the box 1 to between a pair of crushing rollers 2; A drive mechanism, located on housing 1, is used to drive a ring-shaped component 3 to rotate; The housing 1 serves as the main support structure and crushing chamber of the equipment, accommodating all working components and enclosing the crushing process. Meanwhile, a pair of support frames are fixedly installed on the outer wall of the housing 1 to support the housing 1. A pair of crushing rollers 2 are arranged in parallel and rotatably installed inside the housing 1. The gap between the two rollers constitutes the main crushing area, ensuring that the material is efficiently sheared and crushed. A pair of annular components 3 are rotatably mounted on the inner side walls of the housing 1, forming the rotating frame of the circulating conveying mechanism; The conveying shovel 4 is fixedly installed between the two annular parts 3 and rotates synchronously with the annular parts 3. During the rotation, the conveying shovel 4 shovels up the material accumulated at the bottom of the box 1 and re-conveys it to the crushing area between a pair of crushing rollers 2 to achieve cyclic crushing. The drive mechanism can drive one ring part 3 to rotate, at which time another ring part 3 and a pair of conveying shovels 4 can rotate synchronously, so that the conveying shovels 4 can scoop up the material at the bottom of the box 1.

[0021] Specifically, the drive mechanism includes; The first drive motor 5 is fixedly installed on the outer wall of the housing 1, and its output end passes through one side wall of the housing 1. The first gear 6 is fixedly installed at the output end of the first drive motor 5; The external gear ring 7 is fixedly mounted on a ring-shaped part 3 and meshes with the first gear 6; The first drive motor 5 is fixedly installed on the outer wall of the box 1 to prevent the material in the crushing chamber from interfering with the operation of the motor. Its output end passes through one side wall of the box 1 and extends into the interior of the box 1 to realize the transmission of power inside and outside. The first gear 6 is fixedly installed at the output end of the first drive motor 5 and rotates synchronously with the output end of the first drive motor 5. At the same time, it acts as a driving gear, converting the torque of the first drive motor 5 into meshing transmission power. The external gear ring 7 is fixedly installed on the outer circumferential surface of an annular component 3 and forms an external meshing connection with the first gear 6, converting the rotational motion of the first gear 6 into the large-diameter rotational motion of the annular component 3. The rotation of the first gear 6 drives the external gear ring 7 to rotate, and the rotation of the external gear ring 7 drives the annular component 3 fixed to it to rotate synchronously. Because the conveying shovel 4 is fixedly connected to a pair of annular components 3 respectively, it can make the other annular component 3 rotate synchronously, ultimately driving the conveying shovel 4 fixed between the pair of annular components 3 to circulate, shovel and convey the material.

[0022] Specifically, a pair of second gears 8 are provided on one side of the housing 1. The pair of second gears 8 are fixedly connected to one end of a pair of crushing rollers 2, and the pair of second gears 8 are meshed together. A second drive motor 9 is fixedly installed on the outer wall of the housing 1, and the output end of the second drive motor 9 is fixedly connected to one end of a crushing roller 2; The second drive motor 9 is fixedly installed on the outer wall of the housing 1. The output end of the second drive motor 9 is directly fixedly connected to one end of a crushing roller 2 to achieve zero power loss transmission. A pair of second gears 8 are located on the same side of the housing 1. At the same time, the pair of second gears 8 are fixedly connected to the ends of a pair of crushing rollers 2 respectively. The pair of second gears 8 are externally meshed and the tooth surfaces are tightly engaged to transmit torque. The output of the second drive motor 9 can drive a crushing roller 2 and a second gear 8 to rotate simultaneously. At this time, the meshing transmission of one second gear 8 drives another second gear 8 and another crushing roller 2 to rotate simultaneously. The pair of crushing rollers 2 apply shearing force to the material in a counter-rotating manner to achieve efficient crushing.

[0023] Specifically, the lower wall of the box 1 has a discharge port 10, and a baffle 11 for sealing the discharge port 10 is hinged to the lower wall of the box 1. A fixing block 12 is fixedly installed on the lower wall of the box 1. A sliding hole 13 is formed on the fixing block 12. A sliding pin 14 for locking the baffle 11 in the discharge port 10 is slidably installed in the sliding hole 13. A spring 15 is sleeved on the outer surface of the sliding pin 14. The two ends of the spring 15 are fixedly connected to the inner wall of the sliding hole 13 and the outer surface of the sliding pin 14, respectively. The discharge port 10 is formed in the central area of ​​the lower wall of the box 1, serving as the final discharge channel for the crushed material; The baffle 11 is used to seal or open the discharge port 10. It is connected to the lower wall of the box 1 through a hinge structure to achieve rotation around the axis. When the baffle 11 is inside the discharge port 10, it prevents material leakage. The fixing block 12 is fixedly installed on the lower wall of the box 1 near the edge of the baffle 11, and a sliding hole 13 is machined inside it; The sliding pin 14 is slidably installed in the sliding hole 13 and can move axially. When one end extends out of the sliding hole 13, its outer surface contacts the lower end face of the baffle 11, preventing the baffle 11 from opening. Spring 15 is sleeved on the outer surface of sliding pin 14, with one end fixedly connected to the inner wall of sliding hole 13 and the other end fixedly connected to the outer surface of sliding pin 14. It always applies an outward elastic force to sliding pin 14 so that it remains locked to baffle 11. The elastic force of the spring 15 pushes the sliding pin 14 outward, and the outer surface of one end of the sliding pin 14 contacts the lower wall surface of the baffle 11, so that the baffle 11 is forcibly fixed in the discharge port 10. When unlocking the baffle 11, the operator manually pulls one end of the sliding pin 14. The sliding pin 14 compresses the spring 15 and at the same time, the end of the sliding pin 14 that is in contact with the baffle 11 slides into the sliding hole 13 and separates from the baffle 11. The baffle 11 is released from its constraint, flips open, and the material is discharged through the discharge port 10. When the baffle 11 is reset and sealed, flip the baffle 11 to seal the outlet 10, loosen the sliding pin 14, and the spring 15 pushes one end of the sliding pin 14 to automatically pop out of the sliding hole 13 and relock the baffle 11.

[0024] Specifically, the upper wall of the housing 1 is provided with a feed hopper 16; The feed hopper 16 is fixedly connected to the box 1, which allows the operator to easily add materials into the box 1.

[0025] Working principle: Material falls into the housing 1 through the feed hopper 16 and naturally falls into the gap between a pair of crushing rollers 2. The second drive motor 9 starts, driving the crushing roller 2 directly connected to it to rotate. Through a pair of meshing second gears 8, it drives the remaining crushing rollers 2 to rotate in the opposite direction. The pair of crushing rollers 2 use opposing shearing forces to perform initial crushing of the material. After crushing, the material falls to the bottom of the housing 1. The first drive motor 5 starts, driving the first gear 6 to rotate. The rotation of the first gear 6 meshes with and drives the outer gear ring 7 to rotate simultaneously. At this time, the outer gear ring 7 drives a ring component 3 to rotate. Since the conveying shovel 4 is fixedly installed between the pair of ring components 3, the other ring component 3 rotates synchronously. The conveying shovel 4 moves in a circular motion with the ring component. When the conveying shovel 4 rotates to the bottom of the box 1, it scoops up the material again. At this time, the conveying shovel 4 continues to move upward and throws the material back into the crushing area between a pair of crushing rollers 2 to achieve forced cyclic crushing. The material is crushed repeatedly until the particle size meets the standard. The operator manually pulls one end of the sliding pin 14 to compress the compression spring 15, releasing the lock on the baffle 11. The baffle 11 flips open, and the crushed material is discharged through the discharge port 10. When the baffle 11 is reset and sealed, the baffle 11 is flipped so that it is inside the discharge port 10. The sliding pin 14 is released, and the spring 15 pushes the sliding pin 14 to pop out automatically, relocking the baffle.
