Description

Technical Field

[0001] The present application relates to the technical field of crushing devices, and in particular to a powder metallurgy raw material crushing device. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metallic powder) as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. When performing powder metallurgy, the raw ore needs to be crushed by a crusher to facilitate subsequent smelting.

[0003] In the existing technology, jaw crushers are often used to crush raw ore, and the ore is squeezed and crushed by the movement of the movable jaw. However, during the crushing process, since the ore raw materials are crushed by extrusion, when crushing ore with relatively wet and sticky soil on the surface, the soil will adhere to the movable jaw of the crusher and stick to part of the ore, resulting in a waste of part of the raw ore.

[0004] Therefore, the present invention proposes a powder metallurgy raw material crushing device to improve this problem. Summary of the Invention

[0005] The purpose of this application is to solve the problems in the above-mentioned background technology, and to provide a powder metallurgy raw material crushing device.

[0013] Furthermore, an integration plate is slidably installed on the static plate, the tooth plate located on the static plate is installed on the integration plate, and a driving rack is installed on the integration plate. A mounting plate is rotatably installed in the accommodating cavity, and a gear set is rotatably installed on the mounting plate. The number of gears in the gear set is an odd number, and the rotating shaft of the mounting plate passes through the mounting shell and is located on the outside. A rotating disk is installed on the end of the rotating shaft of the mounting plate, and one end of the driving rod passes through the mounting shell and is located on the outside. A driving disk is installed on the end of the driving rod, and a rocker hinged to the rotating disk is hinged on the driving disk. When the driving disk rotates, it drives the rotating disk to swing, so that the head gear or the end gear of the gear set engages with the driving rack.

[0014] Furthermore, the driving member includes a rotating wheel, which is rotatably installed in the accommodating cavity. The rotating wheel is connected to the rotating shaft of the gear set through a pulley assembly. A plurality of resistance plates are installed on the rotating wheel, and a force plate is installed on the shovel plate. When the resistance plate collides with the force plate, the shovel plate is forced to move away from the bottom of the inner wall of the accommodating cavity.

[0015] Furthermore, a connecting pipe is installed on the mounting shell, one end of the connecting pipe is located between the static plate and the movable plate, and the other end of the connecting pipe is located at the discharge port.

[0017] Furthermore, the position of the opening of the communicating pipe on one side between the static plate and the movable plate is lower than the position of the communicating pipe on the outer tube body of the mounting shell.

[0018] Furthermore, a V-shaped plate is installed at the free end of the scraper plate, and the side with the larger opening of the V-shaped plate faces the direction of the discharge port.

[0019] Furthermore, a thick plate and a clamping plate are installed in the accommodating cavity, and a gap for accommodating a shovel plate is provided between the thick plate and the clamping plate.

[0020] The beneficial effects of this application are as follows:

[0021] 1. When the present invention is in use, the rotation of the driving rod drives the hinged rod to pull or push the movable plate, so that the movable plate reciprocates in the accommodating chamber to squeeze and crush the ore. During crushing, the tooth plate increases the contact points between the static plate and the movable plate and the ore, thereby increasing the crushing effect. After the crushing is completed, when the movable plate moves away from the static plate, the teeth and the inclined block interfere with each other, so that the unified plate slides on the movable plate, so that the tooth plate and the push plate move relative to each other, so that the push plate scrapes the gap between the tooth plates, and the shovel plate is driven to slide by the driving member, so that the shovel teeth scrape the gap between the tooth plates on the static plate, thereby reducing the possibility of ore fragments remaining between the tooth plates and reducing the waste of ore.

[0022] 2. The present application has multiple pushing plates, and they are staggered between adjacent through holes, so that when the pushing plate pushes the crushed ore, the crushed ore is pushed toward the through hole. The fixed plate is fixedly installed in the accommodating cavity, so that when the movable plate moves, it also approaches or moves away from the fixed plate. The fixed plate is located on the side of the movable plate away from the static plate, so that when the movable plate approaches the static plate, it is away from the fixed plate, so that when the device crushes the ore, the push rod will not contact the ore, reducing the possibility of the push rod being damaged. When the movable plate is away from the static plate, the movable plate moves in the direction close to the fixed plate, so that the push rod pushes the ore pushed by the pushing plate to the through hole, so that the ore is pushed and separated from the unified plate by the push rod, further increasing the cleaning effect of the crushed ore on the movable plate.

[0023] 3. In the present application, when the movable plate slides, the shielding cover and the rotating gear also slide in the horizontal direction, and then the rotating gear is rotated by the driving of the rotating rack. During use, when the movable plate is close to the static plate, that is, when the device crushes the ore, the rotating rack drives the rotating gear, so that the shielding cover covers the discharge port, reducing the possibility of excessive dust during crushing. When the crushing is completed, the movable plate is away from the static plate, so that the rotating rack drives the rotating gear, so that the shielding cover releases the obstruction of the feed port, making it convenient to add subsequent ore into the accommodating chamber, thereby increasing the practicality of the device.

[0024] 4. In this application, when the driving rod rotates, the driving disc rotates, and then the rotating disc swings, causing the mounting plate to swing, and then the gear in the gear set is intermittently engaged with the driving rack. When the gear in the gear set is engaged with the driving rack, the integration plate is driven away from the bottom of the inner wall of the accommodating cavity. When the mounting plate rotates until the gear is no longer engaged with the driving rack, the integration plate falls until the mounting plate rotates until the gear is engaged with the driving rack again, and the integration plate is driven again. This cycle repeats, so that when the movable plate and the static plate squeeze the ore During crushing, the tooth plate on the static plate also slides on the static plate along with the integration plate, scratching the original ore, further increasing the crushing effect of the device on the original ore, and when in use, the integration plate may generate vibration when falling, thereby further facilitating the falling of the crushed ore on the static plate, increasing the crushing effect while also increasing the cleaning effect of the static plate, and when the integration plate falls, it can produce relative movement with the shovel plate, so that the shovel teeth can better shovel the crushed ore, which also increases the cleaning effect of the crushed ore on the static plate.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0037] Example 1

[0038] like Figure 1 - Figure 10 As shown, the powder metallurgy raw material crushing device proposed in the first embodiment of the present application includes:

[0039] The mounting shell 1 is provided with a holding chamber 101 for holding the raw ore, a static plate 102 and a movable plate 103 are installed in the holding chamber 101, the movable plate 103 is slidably installed in the holding chamber 101, a driving rod 104 is rotatably installed in the holding chamber 101, an eccentric hinged hinged rod 105 is eccentrically hinged on the driving rod 104, the hinged rod 105 is hinged to the movable plate 103, the driving rod 104 includes a disc and a rod body, the disc body is rotatably mounted on the outside of the mounting shell 1, the rod body is eccentrically mounted on the disc body and is located inside the mounting shell 1, the hinged rod 105 is hinged to the rod body, and when in use, the disc body can be moved by a motor or other means The movable plate 103 is driven to rotate, thereby rotating the driving rod 104, and the rod body performs a circular motion around the axis of the disk body. Both sides of the movable plate 103 are in contact with the inner wall of the accommodating chamber 101, and blocks are installed on both sides of the movable plate 103 in the vertical direction in the accommodating chamber 101 to restrict it, so that the movable plate 103 can only slide horizontally in the accommodating chamber 101. The above arrangement makes the movable plate 103, the hinged rod 105 and the driving rod 104 form a structure similar to a crank slider, so that the movable plate 103 reciprocates in the accommodating chamber 101, so that the movable plate 103 can move closer to or away from the static plate 102;

[0040] The tooth plates 2 have a plurality of linear arrays on the movable plate 103 and the static plate 102, and a plurality of slots are provided on the tooth plates 2. The tooth plates 2 transform the contact surfaces between the movable plate 103 and the static plate 102 and the ore into a plurality of contact points after the slots are provided, thereby increasing the pressure when the device resists the ore during crushing, and increasing the crushing effect of the device on the ore. The static plate 102 and the movable plate 103 are both obliquely installed in the accommodating cavity 101, and a V-shape is formed between the two. When in use, when the movable plate 103 approaches the static plate 102, the ore is squeezed and crushed. When the movable plate 103 moves away from the static plate 102, the gap between the two increases, so that the crushed ore is discharged through the inclined guide of the static plate 102, and the uncrushed ore part or the subsequent ore falls due to gravity and is located in the gap to be squeezed and crushed later.

[0041] A unified plate 201 is slidably installed on the movable plate 103, and the tooth plate 2 is installed on the unified plate 201. A pushing plate 206 is installed on the movable plate 103. The unified plate 201 is provided with a groove body that penetrates the unified plate 201 in the gap between adjacent tooth plates 2, and the pushing plate 206 is installed in the groove body. When the unified plate 201 slides on the movable plate 103, the position of the pushing plate 206 remains unchanged, so that relative movement occurs between the two, thereby causing the pushing plate 206 to scrape the crushed ore between the tooth plates 2. When too much crushed ore is attached, the crushed ore that has been attached later is pushed to separate it from the tooth plate 2 and the unified plate 201, thereby reducing the possibility of the crushed ore being attached to the tooth plates 2. The inner walls of the above-mentioned groove body on both sides of the sliding direction of the unified plate 201 are inclined, and the separation of the crushed ore from the unified plate 201 is further facilitated by the guidance of the inclined surface.

[0042] The pushing plate 206 is located between adjacent tooth plates 2, an extension rod 202 is installed on the unified plate 201, and teeth 203 are provided on the extension rod 202. A fluctuating plate 204 is installed in the accommodating cavity 101, and an inclined block 205 is installed on the fluctuating plate 204. When the teeth 203 conflict with the inclined block 205, the unified plate 201 is driven to slide on the movable plate 103, and the extension rod 202 also slides with the movable plate 103. When in use, when the movable plate 103 slides in the accommodating cavity 101, the unified plate 201 and the extension rod 202 are driven to slide together, so that the teeth 203 on the extension rod 202 gradually approach and conflict with the inclined block 205. The guide surface makes the unified plate 201 move away from the bottom of the inner wall of the accommodating chamber 101. When the teeth 203 and the inclined block 205 are no longer in conflict, the unified plate 201 falls under the influence of gravity, so that the unified plate 201 moves back and forth on the movable plate 103 as the movable plate 103 slides, which facilitates the pushing plate 206 to scrape the crushed ore. A spring is installed on the unified plate 201. When the unified plate 201 falls to the lowest point on the movable plate 103 due to gravity, the spring resets and pushes the unified plate 201 during the process, causing it to collide with the movable plate 103, generating vibration, which further facilitates the separation of the crushed ore from the tooth plate 2 and the unified plate 201.

[0043] The shovel plate 3 is slidably installed in the accommodating chamber 101 through the connecting spring 301. The shovel teeth 302 are installed on the shovel plate 3. The spacing between adjacent shovel teeth 302 is less than or equal to the spacing between adjacent tooth plates 2. A driving member 4 connected to the shovel plate 3 is installed in the accommodating chamber 101. The driving member 4 is used to drive the shovel plate 3 to slide. When in use, the shovel plate 3 is driven by the driving member 4 so that the shovel plate 3 and the shovel teeth 302 slide in a direction away from the bottom of the accommodating chamber 101, so that the shovel teeth 302 shovel the crushed ore attached to the static plate 102, so that the crushed ore can fall smoothly;

[0044] When the movable plate 103 is moved away from the static plate 102, the tooth plate 203 and the movable plate 103 are contacted with each other, thereby increasing the crushing effect. After the crushing is completed, when the movable plate 103 is away from the static plate 102, the tooth teeth 203 and the inclined block 205 are in contact with each other, so that the unified plate 201 slides on the movable plate 103, so that the tooth plate 2 and the push plate 206 have relative movement, so that the push plate 206 scrapes the gap between the tooth plates 2, and the shovel plate 3 is driven to slide by the driving member 4, so that the shovel teeth 302 scrape the gap between the tooth plates 2 on the static plate 102, thereby reducing the possibility of ore fragments remaining between the tooth plates 2 and reducing the waste of ore.

[0045] Example 2

[0046] like Figure 8 As shown, the second embodiment is based on the first embodiment and further discloses the movable plate 103, the static plate 102, the mounting shell 1 and the driving member 4. In the second embodiment, a plurality of through holes 5 are opened on the movable plate 103, and the through holes 5 are located in the gaps between the adjacent tooth plates 2. A fixed plate 6 is installed in the accommodating cavity 101, and a plurality of push rods 7 are installed on the fixed plate 6 and slidably inserted in the through holes 5. The axis of the through holes 5 is in the horizontal direction. There are multiple pushing plates 206, and they are staggered between adjacent through holes 5, so that when the pushing plate 206 pushes the crushed ore, the crushed ore is pushed to the through holes 5. The fixed plate 6 is fixedly installed in the accommodating cavity 101, so that when the movable plate When 103 moves, it approaches or moves away from the fixed plate 6. The fixed plate 6 is located on the side of the movable plate 103 away from the static plate 102, so that when the movable plate 103 approaches the static plate 102, it is away from the fixed plate 6, so that when the device crushes the ore, the push rod 7 will not contact the ore, reducing the possibility of damage to the push rod 7. When the movable plate 103 is away from the static plate 102, the movable plate 103 moves toward the direction close to the fixed plate 6, so that the push rod 7 passes through the through hole 5 and pushes the ore pushed by the pushed plate 206 to the through hole 5, so that the ore is pushed by the push rod 7 and separated from the unified plate 201, further increasing the cleaning effect of the crushed ore on the movable plate 103.

[0047] like Figure 1 and Figure 10 As shown, in the second embodiment, the mounting shell 1 is provided with an inlet 106 between the static plate 102 and the movable plate 103, and the mounting shell 1 is provided with an outlet 107 on the side away from the static plate 102. When in use, the raw ore is transported into the accommodating chamber 101 through the inlet 106, and is squeezed and crushed by the movable plate 103 and the static plate 102. When the crushing is completed, the crushed ore is taken out of the device through the outlet 107.

[0048] The movable plate 103 is hinged with a shielding cover 8, and a rotating gear 9 is installed at the hinged rotating shaft of the shielding cover 8. A rotating rack 10 that meshes with the rotating gear 9 is installed on the mounting shell 1. When the movable plate 103 approaches the static plate 102, the shielding cover 8 blocks the feeding port 106. When the movable plate 103 is away from the static plate 102, the shielding cover 8 releases the shielding of the feeding port 106. The rotating gear 9 is fixedly connected to the shielding cover 8. When the movable plate 103 slides, the shielding cover 8 and the rotating gear 9 are also driven to slide in the horizontal direction, and then the rotating rack 10 drives the shielding cover 8 to move horizontally. The movement causes the rotating gear 9 to rotate. During use, when the movable plate 103 is close to the static plate 102, that is, when the device crushes the ore, the rotating rack 10 drives the rotating gear 9, so that the shielding cover 8 covers the feed port 106, reducing the possibility of excessive dust during crushing. When the crushing is completed, the movable plate 103 is away from the static plate 102, so that the rotating rack 10 drives the rotating gear 9, so that the shielding cover 8 releases the obstruction of the feed port 106, making it easier to add subsequent ore into the accommodating chamber 101, thereby increasing the practicality of the device.

[0049] like Figure 4 and Figure 7 As shown, in the second embodiment, an integration plate 11 is slidably mounted on the static plate 102, the toothed plate 2 located on the static plate 102 is mounted on the integration plate 11, a driving rack 1101 is mounted on the integration plate 11, a mounting plate 1102 is rotatably mounted in the accommodating chamber 101, a gear set 1103 is rotatably mounted on the mounting plate 1102, the number of gears in the gear set 1103 is an odd number, a motor is mounted on the mounting plate 1102, a rotating shaft of one of the gears in the gear set 1103 is connected to the motor, and the gear set 1103 is driven by the motor. In normal state, only the gear at the head end or the tail end of the gear set 1103 can mesh with the driving rack 1101, and the rotation of the gear set 1103 causes the driving rack 1101 to drive the integration plate 11 to move in a direction away from the bottom of the inner wall of the accommodating chamber 101;

[0050] The rotating shaft of the mounting plate 1102 passes through the mounting shell 1 and is located outside. A rotating disk 1104 is installed at the end of the rotating shaft of the mounting plate 1102. One end of the driving rod 104 passes through the mounting shell 1 and is located outside. A driving disk 1105 is installed at the end of the driving rod 104. A rocker 1106 hinged to the driving disk 1105 is hinged to the driving disk 1104. When the driving disk 1105 rotates, it drives the rotating disk 1104 to swing, so that the first end gear or the end gear of the gear set 1103 is engaged with the driving rack 1101. The driving disc 1105 is coaxial with the disc body of the driving rod 104. The driving disc 1105, the rocker 1106 and the rotating disc 1104 form a crank rocker structure, so that when the driving rod 104 rotates, the driving disc 1105 is driven to rotate, and then the rotating disc 1104 is driven to swing, so that the mounting plate 1102 swings, and then the gears in the gear set 1103 are driven to intermittently mesh with the driving rack 1101. When the gears in the gear set 1103 are meshed with the driving rack 1101, The integration plate 11 is driven away from the bottom of the inner wall of the accommodating chamber 101. When the mounting plate 1102 rotates until the gear is no longer engaged with the driving rack 1101, the integration plate 11 falls until the mounting plate 1102 rotates until the gear is engaged with the driving rack 1101 again, and the integration plate 11 is driven again. This cycle is repeated, so that when the movable plate 103 and the static plate 102 squeeze and crush the ore, the tooth plate 2 on the static plate 102 also slides on the static plate 102 with the integration plate 11, squeezing the ore. It plays a role of scraping, further increasing the crushing effect of the device on the raw ore, and when in use, the integration plate 11 generates vibration when it falls, which further facilitates the falling of the crushed ore on the static plate 102, thereby increasing the crushing effect and also increasing the cleaning effect of the static plate 102. When the integration plate 11 falls, it can generate relative movement with the shovel plate 3, so that the shovel teeth 302 can better shovel the crushed ore, which also increases the cleaning effect of the crushed ore on the static plate 102;

[0051] The swing of the mounting plate 1102 enables the gears on the gear set 1103 to alternately engage with the drive rack 1101, ensuring that the integration plate 11 can fall within the alternating time, and also increases the frequency of the upward movement of the integration plate 11 and the movement frequency of the tooth plate 2, so that the device can better crush the ore.

[0052] like Figure 7 As shown, in the second embodiment, the driving member 4 includes a rotating wheel 401, which is connected to the rotating shaft of the gear set 1103 through a pulley assembly. The pulley assembly includes two pulleys and a belt for connecting the pulleys, one of which is connected to the gear set 1103 in rotation, and the other is connected to the rotating shaft of the rotating wheel 401, so that when the gear set 1103 rotates, the rotating wheel 401 is also driven to rotate;

[0053] A plurality of contact plates 402 are installed on the rotating wheel 401, and a force plate 403 is installed on the shovel plate 3. When the contact plate 402 conflicts with the force plate 403, the shovel plate 3 is forced to move away from the bottom of the inner wall of the accommodating chamber 101. When the rotating wheel 401 rotates, the contact plate 402 is driven to gradually approach the force plate 403 and conflict with it, and the force plate 403 is lifted upward, so that the shovel plate 3 drives the shovel teeth 302 to move upward to shovel the crushed ore on the static plate 102. When the rotating wheel 401 continues to rotate, the contact plate 402 is driven to release the conflict with the force plate 403, and the connecting spring 301 pulls the shovel plate 3 to reset, which facilitates the shovel plate 3 to move next time, thereby increasing the practicality of the device.

[0054] like Figure 3 、 Figure 6 and Figure 10 As shown, in embodiment 2, a connecting pipe 12 is installed on the mounting shell 1, one end of the connecting pipe 12 is located between the static plate 102 and the movable plate 103, and the other end of the connecting pipe 12 is located at the discharge port 107. A driving motor 13 is installed on the mounting shell 1, and the output shaft of the driving motor 13 is rotatably connected to the driving rod 104 through a pulley assembly. The pulley assembly includes two pulleys and a belt for connecting the pulleys, one of which is connected to the rotating shaft of the driving motor 13, and the other is connected to the disc body of the driving rod 104. The rotation of the driving rod 104 is driven by the driving motor 13;

[0055] A connecting rod 15 is installed on the rotating shaft of the driving motor 13, which is rotatably matched with the mounting shell 1. The connecting rod 15 is located in the accommodating chamber 101, and a fan blade 16 is rotatably installed in the accommodating chamber 101. The fan blade 16 is located at the opening of the connecting pipe 12 on the side facing the discharge port 107. The rotating shaft of the fan blade 16 is connected to the connecting rod 15 through a pulley assembly. The pulley assembly includes two pulleys and belts for connecting the pulleys, one of which is connected to the connecting rod 15, and the other is connected to the rotating shaft of the fan blade 16. In use, when the driving motor 13 rotates, the fan blade 16 is driven to rotate through the connecting rod 15 and the pulley assembly, thereby causing the fan blade 16 to pump the air flow in the connecting pipe 12, so that the fan blade 16 acts as an exhaust fan relative to the connecting pipe 12, thereby causing the dust generated by the device to be sucked into the connecting pipe 12 when the ore is crushed, further reducing the possibility of dust generated by the device and reducing the possibility of dust inhalation by the operator.

[0056] Example 3

[0057] like Figure 1 - Figure 10As shown, the third embodiment is further disclosed on the basis of the second embodiment of the present application. In the third embodiment, a horizontal plate 18 is installed on the movable plate 103, a scraping plate 17 is hinged on the horizontal plate 18, and a shielding plate 19 is installed on the horizontal plate 18. The shielding plate 19 is located on the side of the scraping plate 17 close to the movable plate 103, so that the angle between the scraping plate 17 and the horizontal plate 18 close to the side of the movable plate 103 is always maintained greater than or equal to ninety degrees. When the movable plate 103 moves away from the static plate 102, it drives the scraping plate 17 to move in the direction close to the discharge port 107. Due to the shielding plate 19 blocks the scraper plate 17 so that it cannot be rotated by the crushed ore, so that the scraper plate 17 can hard contact with the crushed ore, and push the crushed ore accumulated below the static plate 102 and the movable plate 103 toward the discharge port 107, thereby reducing the possibility of the movable plate 103 being stuck due to excessive accumulation of crushed ore. When the movable plate 103 moves toward the static plate 102, if there are still some crushed ore on the path of the scraper plate 17 when it is reset at the bottom of the accommodating chamber 101, the scraper plate 17 can be reset normally through the rotation of the scraper plate 17, thereby increasing the practicality of the device.

[0058] In embodiment three, the position of the opening on one side of the connecting pipe 12 between the static plate 102 and the movable plate 103 is lower than the position of the connecting pipe 12 on the external tube body of the mounting shell 1. The side of the connecting pipe 12 close to the feed port 106 is inclined. When pumping, dust will float upward when it is generated. By tilting the connecting pipe 12, the dust can be better moved into the connecting pipe 12, which facilitates the dust to enter the connecting pipe 12, thereby increasing the dust collection effect of the device.

[0059] In embodiment three, a V-shaped plate 20 is installed at the free end of the scraper plate 17, and the side with the larger opening of the V-shaped plate 20 is facing the direction of the discharge port 107. When the scraper plate 17 is driven by the horizontal plate 18, the opening of the V-shaped plate 20 pushes the crushed ore. However, when the scraper plate 17 is reset, there is crushed ore blocking it below and it is in an inclined state. The smaller end of the V-shaped plate 20 is mounted on the crushed ore. When the scraper plate 17 moves again, the V-shaped plate 20 will generate an oblique downward force on the crushed ore below it, and then generate a component force toward the discharge port 107, further increasing the pushing effect of the scraper plate 17 on the crushed ore.

[0060] In embodiment three, a thick plate 21 and a clamping plate 14 are installed in the accommodating cavity 101, and there is a gap between the thick plate 21 and the clamping plate 14 for accommodating the shovel plate 3. The thick plate 21 is used to support the shovel plate 3 so that the shovel plate 3 can be more stable during movement, and the shovel plate 3 is restricted by the gap between the thick plate 21 and the clamping plate 14, so that the sliding direction of the shovel plate 3 is restricted, thereby increasing the stability of the shovel plate 3 during sliding.

[0061] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
