For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0034] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Reference Figure 1 and Figure 2This application provides a metal raw material crushing device, including a housing 1. The housing 1 is characterized by having a crushing mechanism 2 for crushing metal raw materials and a collection and screening mechanism 3 for collecting and screening the crushed metal raw materials. The crushing mechanism 2 includes a connecting block 204 and a rotating shaft 206. The rotating shaft 206 is rotatably connected to one side of the housing 1. The connecting block 204 passes through one side of the housing 1 and is rotatably connected to it. The connecting block 204 is slidably connected to the inner wall surface of the rotating shaft 206. The metal raw materials to be crushed can be fed into the device through the feed pipe 201 on the upper surface of the housing 1, causing the metal raw materials to fall into the crushing mechanism 2. The material is fed into the crushing rollers 203 inside the connecting box 202. Then, the motor 209 is started, driving the first gear 207 to rotate. Through the meshing transmission between the first gear 207 and the second gear 208, the two rotating shafts 206 rotate in opposite directions, thereby driving the crushing rollers 203 to rotate. The teeth on the surfaces of the two crushing rollers 203 generate shearing force, crushing the raw material. When the crushing rollers 203 are worn and need replacement, the fixing bolts between the pull plate 210 and the fixing plate 211 are loosened, and the pull plate 210 is pulled outwards, causing the connecting box 202 to slide out along the inner wall of the housing 1. This separates the connecting block 204 of the crushing rollers 203 from the T-shaped groove of the rotating shaft 206, allowing the old rollers to be disassembled as a whole. The crushed material can fall from the gap between the crushing rollers 203 into the collection box 301 below through the collection and screening mechanism 3. The vibrating motor 303 drives the screen plate 302 to vibrate at high frequency, performing particle size screening of the material. Material of the correct particle size passes through the holes in the sieve plate 302 and slides down the inclined plate 304 into the discharge pipe 305. The baffle 308 inside the discharge pipe 305 is initially closed. When the correct material accumulates to a certain height in the collection box 301, the electric push rod 307 is activated. The electric push rod 307 pushes the baffle 308 to slide laterally, opening the discharge port, and the material is discharged through the discharge pipe 305. During operation, the rubber pad 309 absorbs the vibration energy of the equipment through its elastic material, reducing the impact on the ground and lowering the noise generated during operation.

[0036] Reference Figure 2 and Figure 3 In one aspect of this embodiment, a feed pipe 201 is fixedly installed on the upper surface of the box 1, a connecting box 202 is slidably connected to the inner wall surface of the box 1, a crushing roller 203 is rotatably connected to both sides of the inner wall of the connecting box 202, a connecting block 204 is fixedly installed at one end of the crushing roller 203, and the connecting block 204 passes through one side of the connecting box 202 and is slidably connected to one side of the connecting box 202.

[0037] A pull plate 210 is fixedly installed on the other side of the connecting box 202, and a fixing plate 211 is fixedly installed on both sides of the box body 1. The pull plate 210 is slidably connected to the inner wall surface of the fixing plate 211, and the pull plate 210 is fixedly installed on the inner wall surface of the fixing plate 211 by bolts.

[0038] A mounting box 205 is fixedly installed on one side of the housing 1. A first gear 207 is fixedly installed at one end of a rotating shaft 206. There are two rotating shafts 206, and a second gear 208 is fixedly installed at one end of each rotating shaft 206. The first gear 207 and the second gear 208 mesh. A motor 209 is fixedly installed on one side of the mounting box 205. The output shaft of the motor 209 is fixedly connected to the first gear 207. The metal raw material to be crushed is fed into the device through the feed pipe 201 on the upper surface of the housing 1, causing the metal raw material to fall between the crushing rollers 203 in the connecting box 202. Then, the motor 209 is started. 209 drives the first gear 207 to rotate. Through the meshing transmission between the first gear 207 and the second gear 208, the two rotating shafts 206 are driven to rotate in opposite directions, which in turn drives the crushing roller 203 to rotate. The teeth on the surface of the two crushing rollers 203 form a shearing force to crush the raw material. When the crushing roller 203 is worn and needs to be replaced, loosen the fixing bolts between the pull plate 210 and the fixing plate 211, pull the pull plate 210 outward, and drive the connecting box 202 to slide out along the inner wall of the box 1, so that the connecting block 204 of the crushing roller 203 is separated from the T-shaped groove of the rotating shaft 206, and the old roller can be disassembled as a whole.

[0039] Reference Figure 4 and Figure 5 In one aspect of this embodiment, a collection box 301 is slidably connected to the inner wall surface of the box 1, a sieve plate 302 is fixedly installed on the inner wall surface of the collection box 301, a vibration motor 303 is fixedly installed on one side of the collection box 301, and the output shaft of the vibration motor 303 is fixedly connected to the sieve plate 302.

[0040] Inclined plates 304 are fixedly installed on both sides of the inner wall of the collection box 301. A discharge pipe 305 is fixedly installed on one side of the collection box 301. An installation plate 306 is fixedly installed on the upper surface of the discharge pipe 305. An electric push rod 307 is fixedly installed on one side of the installation plate 306.

[0041] A baffle 308 is slidably connected to the inner wall surface of the discharge pipe 305. The baffle 308 passes through one side of the discharge pipe 305 and is slidably connected to one side of the discharge pipe 305. The other end of the electric push rod 307 is fixedly installed on one side of the baffle 308. A rubber pad 309 is fixedly installed on the lower surface of the box 1. The crushed material falls from the gap of the crushing roller 203 into the collection box 301 below. The vibrating motor 303 drives the screen plate 302 to vibrate at high frequency to screen the material by particle size. The material with qualified particle size slides down the inclined plate 304 to the discharge pipe 305 through the holes of the screen plate 302. The baffle 308 in the discharge pipe 305 is initially closed. When the qualified material in the collection box 301 accumulates to a certain height, the electric push rod 307 is activated. The electric push rod 307 pushes the baffle 308 to slide laterally, opening the discharge port, and the material is discharged through the discharge pipe 305. When the device is in use, the rubber pad 309 absorbs the vibration energy generated during operation through its elastic material, reducing the impact on the ground and lowering the noise generated during device use.

[0042] All electrical devices in this plan are powered by an external power source.

[0043] Working Principle: When using this device, the metal raw material to be crushed is fed into the device through the feed pipe 201 on the upper surface of the housing 1, causing the metal raw material to fall between the crushing rollers 203 inside the connecting box 202. Then, the motor 209 is started, driving the first gear 207 to rotate. Through the meshing transmission between the first gear 207 and the second gear 208, the two rotating shafts 206 are driven to rotate in opposite directions, thereby driving the crushing rollers 203 to rotate. The teeth on the surfaces of the two crushing rollers 203 generate shearing force, crushing the raw material. The crushed material falls from the gap between the crushing rollers 203 into the collection box 301 below. The vibrating motor 303 drives the screen plate 302 to vibrate at high frequency, performing particle size screening of the material. Material of the correct particle size passes through the holes in the sieve plate 302 and slides down the inclined plate 304 to the discharge pipe 305. The baffle 308 inside the discharge pipe 305 is initially closed. When the qualified material in the collection box 301 accumulates to a certain height, the electric push rod 307 is activated. The electric push rod 307 pushes the baffle 308 to slide laterally, opening the discharge port, and the material is discharged through the discharge pipe 305. During use, the rubber pad 309 absorbs the vibration energy of the equipment during operation through its elastic material, reducing the impact on the ground and lowering the noise generated during use. When the crushing roller 203 is worn and needs to be replaced, loosen the fixing bolts between the pull plate 210 and the fixing plate 211, pull the pull plate 210 outward, and drive the connecting box 202 to slide out along the inner wall of the box 1, so that the connecting block 204 of the crushing roller 203 separates from the T-shaped groove of the rotating shaft 206, and the old roller can be disassembled as a whole.
