If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference Figures 1 to 3 , which is a durable crusher according to an embodiment of the utility model, includes a machine base 100, a crushing assembly 200 and a feeding structure 300. The machine base 100 is provided with a crushing chamber 110, and a crushing inlet is provided at the upper end of the crushing chamber 110; the crushing assembly 200 is provided on the machine base 100, and the crushing assembly 200 includes a crushing knife 210 and a crushing driver 220, the crushing knife 210 is rotatably provided on the machine base 100 and is located in the crushing chamber 110, and the crushing driver 220 is used to drive the crushing knife 210 to rotate; the feeding structure 300 is provided on the machine base 100, and the feeding structure 300 is provided with a feeding channel 310 and a deceleration part 320, the upper end of the feeding channel 310 is provided with a feeding port 330, and the lower end of the feeding channel 310 is provided with a discharge port 340, the discharge port 340 is connected with the crushing inlet, the feeding port 330 and the discharge port 340 are vertically opposite, and the deceleration part 320 is located in the feeding channel 310 and between the feeding port 330 and the discharge port 340.

[0034] When the equipment is in operation, the crushing driver 220 drives the crushing knife 210 to rotate and crush the material. The material is put into the feed port 330 of the feeding structure 300. During the process of the material descending along the feed channel 310, it will be rapidly accelerated under the action of gravity. At this time, the deceleration part 320 slows down the vertical movement speed of the material, so that when the material falls into the crushing chamber 110, the vertical speed of the material is low, reducing the wear and damage of the crushing knife 210 caused by the impact force when the material falls on the crushing knife 210, thereby improving the durability of the crusher.

[0035] Specifically, the crushing driver 220 uses a motor, and the motor can drive the crushing blade 210 to rotate by belt transmission or gear transmission. It is conceivable that the crushing driver 220 can also use other output structures, such as an internal combustion engine.

[0036] In the embodiment, the feed channel 310 is arranged at an angle, and the deceleration part 320 is an inclined channel wall of the feed channel 310. The vertical speed of the falling material is slowed down by the inclined channel wall, which has a simple structure and is easy to implement; and the feed channel 310 is arranged at an angle, so that when the material at the crushing chamber 110 is hit by the crushing knife 210 and splashes into the feed channel 310, the splashed material can be blocked by the inclined side wall of the feed channel 310 and cannot splash out from the feed port 330, thereby avoiding the risk of splashing material splashing out from the feed port 330, and the inclined channel wall can also buffer the vertical speed of the material when it falls, reducing the wear of the crushing knife 210 when the material falls into the crushing knife 210. It is conceivable that the deceleration part 320 can also be an inclined friction plate arranged in the feed channel 310, and when the material touches the friction plate, the vertical speed can be slowed down. It is conceivable that the feed channel 310 can also be partially inclined.

[0037] In the embodiment, the feed channel 310 includes an upper channel section 311 and a lower channel section 312. The upper channel section 311 is tilted and arranged downward and backward, and the lower channel section 312 is tilted and arranged downward and forward. The lower end of the upper channel section 311 is connected to the upper end of the lower channel section 312, and the upper channel section 311 and the lower channel section 312 are perpendicular to each other. Since the upper channel section 311 and the lower channel section 312 are perpendicular to each other, the material splashed from the crushing chamber 110 cannot turn multiple times and enter the upper channel section 311, further reducing the risk of material splashing from the feed port 330; and can better slow down the vertical speed of the material.

[0038] It is conceivable that the feed channel 310 may also be in the shape of an inclined straight line, and those skilled in the art may configure the feed channel 310 according to actual needs.

[0039] In the embodiment, a feeding locking mechanism 400 is further included. One side of the feeding structure 300 is rotatably connected to the base 100 and can be rotated to block or open the crushing entrance. The feeding locking mechanism 400 is arranged between the base 100 and the feeding structure 300 and can lock or unlock the position of the feeding structure 300 relative to the base 100. When it is necessary to clean and maintain the inside of the crushing chamber 110, the feeding locking mechanism 400 can be unlocked, and then the feeding structure 300 can be rotated to open the crushing entrance. At this time, the production staff can clean and maintain the inside of the crushing chamber 110. After the cleaning and maintenance is completed, the production staff can rotate the feeding structure 300 back to block the crushing entrance, and use the feeding locking mechanism 400 to lock the position of the feeding structure 300 relative to the base 100, thereby reducing the risk of the crushing entrance being accidentally opened, and the use is flexible and convenient, and the safety is improved.

[0040] In an embodiment, the feeding locking mechanism 400 includes a locking block 410, a handle 420 and a screw 430, one end of the screw 430 is fixedly connected to the handle 420, and the other end of the screw 430 is threadedly connected to the locking block 410, the locking block 410 is pivotally connected to the base 100, and a mating portion 350 is provided on the other side of the feeding structure 300, and the side of the handle 420 close to the locking block 410 can abut or separate from the mating portion 350. When the feeding locking mechanism 400 locks the feeding structure 300, the screw 430 and the locking block 410 are in a tightened state. At this time, the side of the handle 420 close to the locking block 410 abuts against the matching part 350, limiting the rotation of the feeding structure 300; when it is necessary to unlock the feeding locking mechanism 400, loosen the handle 420 and the screw 430 so that the handle 420 does not abut against the matching part 350. At this time, the locking block 410 can be rotated to rotate the handle 420 to avoid the rotation path of the matching part 350. At this time, the feeding structure 300 can be rotated to open the crushing entrance.

[0041] In an embodiment, the feeding structure 300 is provided with a sound insulation structure, and the sound insulation structure is arranged around the periphery of the feeding channel 310. The sound insulation structure can reduce the noise to the outside when the material collides with the channel wall of the feeding channel 310.

[0042] In the embodiment, the sound insulation structure includes a sound insulation cavity 380, the feeding structure 300 includes an outer shell 360 and an inner tube 370, the inner tube 370 forms a feeding channel 310, and the outer shell 360 is sleeved on the outer side of the inner tube 370 and enclosed with the inner tube 370 to form a sound insulation cavity 380. The sound insulation cavity 380 is formed by the outer shell 360 and the inner tube 370, and the collision of materials in the feeding channel 310 is soundproofed, thereby reducing the amplitude of noise transmitted to the outside, achieving a noise reduction effect.

[0043] Furthermore, sound insulation cotton can be arranged in the sound insulation cavity 380, and the sound insulation cotton can further absorb the noise inside the feed channel 310, thereby further improving the noise reduction effect.

[0044] It is conceivable that the sound insulation structure may also be other structures. For example, the sound insulation structure is a sound insulation cotton sleeve that is sleeved on the outer periphery of the feeding structure 300 to absorb and reduce the noise in the feeding channel 310.

[0045] In the embodiment, the base 100 is detachably provided with a collecting box 500, the crushing chamber 110 is provided with a crushing outlet, and the collecting box 500 is located below the crushing outlet. The crushed materials enter the collecting box 500 for collection. When the materials are full, the collecting box 500 can be disassembled from the base 100 and the materials can be moved to a designated location.

[0046] In the embodiment, the base 100 is provided with a slide groove in a slanting downward direction, the collection box 500 is provided with a slider, the slider is slidably connected to the slide groove, and the base 100 is provided with a stopper 120, which is opposite to the lower end of the slide groove. The collection box 500 is slidably connected to the slide groove of the base 100 through the slider, and the stopper 120 limits the position of the collection box 500 in a natural state, so that the collection box 500 remains fixed; when the collection box 500 needs to be disassembled, the collection box 500 is dragged slanting upward along the extension direction of the slide rail, so that the slider of the collection box 500 is separated from the high end of the slide rail, and the collection box 500 is disassembled at this time. When the collection box 500 needs to be installed, the slider is moved in from the high end of the slide rail, and the collection box 500 will slide down along the slide rail under the action of gravity, and finally be limited by the stopper 120. The above structure can automatically position the collection box 500, and the disassembly structure and method are relatively simple and easy to implement.

[0047] It is conceivable that a through hole may be provided in the collection box 500, a threaded hole may be provided in the base 100, a screw may be passed through the through hole, and the screw may be threadedly connected to the threaded hole to detachably connect the collection box 500 to the base 100. When the collection box 500 needs to be disassembled, the screw may be loosened.

[0048] In the embodiment, a collection locking mechanism 600 is further included, which is disposed between the base 100 and the collection box 500 and is used to unlock or lock the position of the collection box 500 relative to the base 100. Providing the collection locking mechanism 600 can reduce the risk of the collection box 500 being accidentally disassembled.

[0049] Specifically, the collection locking mechanism 600 includes a limit plate and a screw. The limit plate is provided with a through hole, the machine base 100 is provided with a threaded hole, the screw is passed through the through hole and is threadedly connected to the threaded hole, and the limit plate can rotate around the screw to limit or avoid the collection box 500 away from the stopper 120. When the screw is loosened, the collection locking mechanism 600 can limit or avoid the collection box 500 by rotating the limit plate. When the limit plate limits the collection box 500, the collection box 500 cannot be disassembled. When the limit plate avoids the collection box 500, the collection box 500 can be disassembled, and the position of the limit plate can be maintained by tightening the screw. The locking or unlocking method is relatively simple and convenient to use.

[0050] It is conceivable that the collection locking mechanism 600 can also be other structures. For example, the collection locking mechanism 600 is a screw, a threaded hole is set in the base, and a through hole is set in the collection box 500. The screw is passed through the through hole and threadedly connected to the threaded hole. When the screw is tightened, the position of the collection box 500 is locked; when the screw is loosened, the position of the collection box 500 is unlocked.

[0051] In the embodiment, a screen member 700 and a position limiting net 800 are also included. The screen member 700 is arranged on the machine base 100 and covers the crushing outlet. The position limiting net 800 is arranged on the machine base 100 and is located below the screen member 700. The screen member 700 and the position limiting net 800 are located above the collection box 500. The screen member 700 is provided with a certain number of meshes, and the meshes can allow small particles in the crushing chamber 110 to pass through, while large particles continue to stay in the crushing chamber 110 for crushing; at the same time, in order to reduce the risk of the screen member 700 falling into the collection box 500, a position limiting net 800 is also provided. When the screen member 700 falls off, the position limiting net 800 can stop the position of the screen member 700, and the structure of the position limiting net 800 also allows small particles to pass through, and the structure is simple, reducing safety risks. Specifically, the mesh cross section of the position limiting net 800 is larger than the mesh cross section of the screen member 700.
