[0033] Reference Figures 1 to 4, is a pulverizer that can adapt to different materials according to an embodiment of the utility model, including a base 100, a pulverizing assembly 200 and a hopper 300. The base 100 is provided with a pulverizing chamber 110, the upper end of the pulverizing chamber 110 is provided with a feed inlet 120, and the lower end of the pulverizing chamber 110 is provided with a discharge port 130; the pulverizing assembly 200 is provided on the base 100, and the pulverizing assembly 200 includes a pulverizing knife 210, and the pulverizing knife 210 is rotatably provided in the pulverizing chamber 110; the hopper 300 is provided above the base 100, and the hopper 300 is provided with a feed channel 310, and the hopper 300 is provided with a feed channel 310. The feed port 320 connected to the upper end and the discharge port 330 connected to the lower end of the feed channel 310, the feed port 320 and the discharge port 330 are arranged vertically, the discharge port 330 is connected to the feed port 120, the hopper 300 is rotatably provided with a deceleration plate 340, the deceleration plate 340 is tilted downward and the tilt angle is adjustable, the deceleration plate 340 forms a partial channel wall of the feed channel 310, and the deceleration plate 340 is located between the feed port 320 and the discharge port 330.

[0034] When switching different types of materials to be put into the hopper 300, if the material is easy to stagnate on the deceleration plate 340, the inclination angle of the deceleration plate 340 relative to the horizontal direction is adjusted to increase to reduce the ability of the deceleration plate 340 to slow down the material movement speed, thereby avoiding the material from stagnating on the deceleration plate 340; if the deceleration plate 340 is not good at slowing down the material movement speed, the inclination angle of the deceleration plate 340 relative to the horizontal direction can be adjusted to decrease to improve the ability of the deceleration plate 340 to slow down the material movement speed; by adjusting the inclination angle of the deceleration plate 340 to adapt to the deceleration of different types of materials, the crusher can adapt to different types of materials and effectively ensure the normal operation of the equipment.

[0035] In the embodiment, a tilting driver 400 is further included, the upper end of the deceleration plate 340 is pivotally connected to the channel wall of the feed channel 310, the hopper 300 includes a body 350, and the tilting driver 400 is disposed between the body 350 and the deceleration plate 340 and can drive the deceleration plate 340 to rotate. The deceleration plate 340 is driven to rotate and adjust the tilt angle by the tilting driver 400, providing a basis for automatic control of the equipment, and facilitating the operation and use of the equipment.

[0036] In the embodiment, the tilting driver 400 includes a fixed portion and a linear telescopic portion, the linear telescopic portion is telescopically arranged on the fixed portion, the fixed portion is pivotally connected to the body 350, and the linear telescopic portion is pivotally connected to the lower portion of the deceleration plate 340. Since the upper portion of the deceleration plate 340 is pivotally connected to the body 350 of the hopper 300, when the linear telescopic portion is extended relative to the fixed portion, the tilting driver 400 is extended as a whole, and at this time, the tilting driver 400 pushes the deceleration plate 340 to rotate, so that the inclination angle of the deceleration plate 340 relative to the horizontal direction is reduced, that is, the deceleration plate 340 is closer to the horizontal direction, and the deceleration effect on the material can be improved at this time; when the linear telescopic portion is retracted relative to the fixed portion, the tilting driver 400 is shortened as a whole, and at this time, the tilting driver 400 pulls the deceleration plate 340 to rotate, so that the inclination angle of the deceleration plate 340 relative to the horizontal direction is increased, that is, the deceleration plate 340 is closer to the vertical direction, and the deceleration effect on the material can be reduced at this time.

[0037] Specifically, the upper side of the deceleration plate 340 is relatively rough or uneven, so that the effect of decelerating the material is better.

[0038] Specifically, the tilt driver 400 can adopt a structure with adjustable telescopic length such as an electric cylinder and a linear motor; or the tilt driver 400 can also adopt a rotating motor, which is connected to the rotating shaft at the upper end of the deceleration plate 340 through a gear set to drive the deceleration plate 340 to rotate and adjust the angle.

[0039] It is conceivable that the inclination angle of the deceleration plate 340 can also be adjusted manually, for example, a plurality of latch holes are arranged around the rotation axis of the deceleration plate 340 on the channel wall of the feed channel 310, and a limit latch is inserted into one of the latch holes, which supports the lower side of the deceleration plate 340 and stops the rotation of the deceleration plate 340. By switching different latch holes to install the limit latch, the inclination angle of the deceleration plate 340 can be adjusted in multiple gears.

[0040] In the embodiment, the hopper 300 is rotatably provided with a lower connecting plate 360, the upper end of the lower connecting plate 360 ​​is slidably connected to the deceleration plate 340 along the inclined direction of the deceleration plate 340, and the lower connecting plate 360 ​​forms a part of the channel wall of the feed channel 310. The lower connecting plate 360 ​​is provided, and when the deceleration plate 340 rotates, the lower connecting plate 360 ​​adaptively rotates with the rotation of the deceleration plate 340, and the upper end of the lower connecting plate 360 ​​can always be connected to the deceleration plate 340, so as to avoid a large gap in the feed channel 310, which causes material leakage, and has a simple structure and is easy to implement.

[0041] In the embodiment, the feed channel 310 includes an upper feed section 311 and a lower feed section 312, both of which are inclined, the lower end of the upper feed section 311 is butted with the upper end of the lower feed section 312, the deceleration plate 340 is located in the upper feed section 311, and the lower connecting plate 360 ​​is located in the lower feed section 312. The feed channel 310 has a simple structure and is easy to implement. The inclined upper feed section 311 and the lower feed section 312 enable the entire feed channel 310 to have a certain material deceleration effect.

[0042] In the embodiment, the upper feed section 311 is tilted toward the lower right direction and the lower feed section 312 is tilted toward the lower left direction. With the above structure, when the crushing knife 210 crushes the material and the material splashes from the feed port 120 into the lower feed section 312, the material is difficult to turn and enter the upper feed section 311, thereby avoiding the risk of the material splashing from the feed hopper 300 and escaping from the hopper 300, thereby improving the safety of the crusher. It is understandable that the upper feed section 311 can also be tilted toward the lower left direction and the lower feed section 312 can be tilted toward the lower right direction, which also has the same effect.

[0043] In the embodiment, the deceleration plate 340 is provided with a slide groove 341 extending along its tilting direction, the notch of the slide groove 341 is provided along the front-rear direction, and the lower connecting plate 360 ​​is provided with a connecting shaft 361 along the front-rear direction, and the connecting shaft 361 is slidably connected to the slide groove 341. The lower connecting plate 360 ​​is slidably connected to the slide groove 341 through the connecting shaft 361, and when the deceleration plate 340 is rotated to adjust the tilting angle, the lower connecting plate 360 ​​can be driven to rotate through the slide groove 341 and the rotation, and the lower connecting plate 360 ​​is always connected to the deceleration plate 340, so that the feed channel 310 will not have a gap due to the rotation of the deceleration plate 340, and the structure is relatively simple.

[0044] Specifically, the lower end of the lower connecting plate 360 ​​is pivotally connected to the body 350 of the hopper 300 .

[0045] It is conceivable that the deceleration plate 340 can also be provided with an iron plate, and a magnet can be provided at the upper end of the lower connecting plate 360. The magnet is magnetically connected to the lower side of the deceleration plate 340. When the deceleration plate 340 rotates, the magnet slides along the deceleration plate 340, driving the lower connecting plate 360 ​​to rotate adaptively. Alternatively, a roller groove can be provided along the tilting direction of the deceleration plate 340, and a roller can be rotatably provided at the upper end of the lower connecting plate 360. The roller is connected to the roller groove and can roll along the roller groove. When the deceleration plate 340 rotates to adjust the tilting angle, the lower connecting plate 360 ​​can be driven to rotate via the roller groove and the roller.

[0046] In the embodiment, both the front and rear sides of the deceleration plate 340 are provided with slide grooves 341, and the connecting shaft 361 is slidably connected to the two slide grooves 341. The two slide grooves 341 are provided so that when the connecting shaft 361 slides along the inclined direction of the deceleration plate 340, the sliding can be more stable, so that the upper end of the deceleration plate 340 and the lower connecting plate 360 ​​are connected more stably and firmly.

[0047] In the embodiment, a screen 500 is further included, which is disposed on the base 100 and located in the crushing chamber 110. The screen 500 is located below the crushing blade 210. The screen 500 is arc-shaped, and the center of the screen 500 is located on the rotation axis of the crushing blade 210. The arc-shaped screen 500 allows large particles that have not passed through the screen 500 to be more easily re-contacted and crushed by the crushing blade 210, thereby improving the crushing effect of the crushing blade 210.

[0048] Specifically, the crushing assembly 200 further includes a crushing driver 220, which drives the crushing blade 210 to rotate by belt transmission. Specifically, the crushing driver 220 uses a motor. It is conceivable that the crushing driver 220 can also use a structure that outputs rotational power such as an internal combustion engine, and the crushing driver 220 can also drive the crushing blade 210 to rotate by a gear set transmission.

[0049] In the embodiment, the machine base 100 includes a crushing seat 140 and a collecting seat 150. The crushing seat 140 is provided with a first chamber, and the collecting seat 150 is provided with a second chamber. The first chamber is connected to the second chamber to form a crushing chamber 110. The crushing seat 140 is pivoted to the collecting seat 150 and can be rotated to separate and open the first chamber and the second chamber. A locking mechanism 600 is provided between the crushing seat 140 and the collecting seat 150 for limiting or allowing the crushing seat 140 to rotate relative to the collecting seat 150. In a normal use state, the first chamber and the second chamber are connected to form the crushing chamber 110, and the locking mechanism 600 limits the crushing seat 140 from rotating relative to the collecting seat 150. When it is necessary to clean and maintain the inside of the crushing chamber 110, the locking mechanism 600 is unlocked, and the crushing seat 140 is rotated so that the first chamber and the second chamber are separated and opened from each other. At this time, the inside of the first chamber and the second chamber can be cleaned and maintained, that is, the crushing chamber 110 can be cleaned and maintained.

[0050] Specifically, the locking mechanism 600 includes a hand screw, the right side of the crushing seat 140 is pivotally connected to the collecting seat 150, the locking mechanism 600 is located on the left side of the crushing seat 140, and the hand screw is threadedly connected to the crushing seat 140. When the hand screw is tightened, the hand screw locks the crushing seat 140 and the collecting seat 150 to limit the relative rotation between the two; when the hand screw is loosened, the hand screw can avoid the collecting seat 150, so that the crushing seat 140 can rotate relative to the collecting seat 150, so that the first chamber and the second chamber are separated and opened.

[0051] It is conceivable that the locking mechanism 600 may also include an electromagnet and an iron block, wherein the iron block is disposed on the crushing seat 140 and the electromagnet is disposed on the collecting seat 150. When the electromagnet is activated, the electromagnet magnetically attracts the iron block to restrict the crushing seat 140 from rotating relative to the collecting seat 150. When the electromagnet is turned off, the crushing seat 140 can rotate relative to the collecting seat 150.

[0052] Specifically, the collecting seat 150 is provided with a collecting box 700 , and an opening of the collecting box 700 is located below the discharge port 130 .
