[0027] like Figures 1-3 As shown, this utility model proposes a quick-change screen structure 1000 for an extrusion crusher, comprising: a housing 100; a crushing jaw assembly 200, which is fixedly disposed inside the housing 100; and a quick-change component 300, which includes a mounting groove 310 and a fixing member 320. The mounting groove 310 is fixedly disposed on the housing 100 near the crushing jaw assembly 200 and located vertically below the crushing jaw assembly 200. The mounting groove 310 is an arc-shaped groove structure with a horizontal opening. The housing 100 has a quick-change port 110 at the position of the horizontal opening of the mounting groove 310. The fixing member 320 abuts against the inner wall of the mounting groove 310, and the inner side of the fixing member 320 has a fixing cavity. The screen 400 includes a frame 410 and a screen surface 420. The frame 410 abuts against the fixing member 320 and is located in the fixing cavity. The frame 410 has a central cavity in the vertical direction. The screen surface 420 is set in the central cavity of the frame 410. The screen surface 420 and the frame 410 are connected by bolts.

[0028] In this embodiment, the compression crusher is a jaw crusher, and the shell 100 is the outer shell of the jaw crusher. The top of the jaw crusher is the feed end, and the bottom is the discharge end. Inside the shell 100 of the jaw crusher, there is a jaw crushing assembly 200, which is used to crush and disperse agglomerated fertilizer particles. The crushed and dispersed fertilizer is screened and filtered through a screen 400 set at the bottom of the shell 100. After removing unscreened stones, stalks, and other impurities, the operator will screen larger fertilizer clumps again until the fertilizer particles meet the production requirements. When it is necessary to quickly disassemble and replace the screen 400, the fixing part 320 is pulled out from the quick-change port 110 on the shell 100 along the opening direction of the mounting groove 310, and then the bolts used for fixing on the fixing part 320 are removed, and the screen 400 composed of the frame 410 and the screen 420 is disassembled and replaced. It is understandable that in the prior art, the screen 400 is fixedly welded or threaded onto the crusher housing 100, requiring a long downtime for replacement. However, the present invention can use multiple fixing parts 320 and screens 400. After the operator removes the screen 400 to be replaced and the fixing part 320 from the housing 100, the new screen 400 and the fixing part 320 can be inserted into the housing 100. Replacement can be performed only during the intervals between the various processes inherent in the production process, achieving a quick replacement effect. At the same time, by fixing the screen 400 in the fixing part 320 and then in the mounting groove 310, stress transfer is achieved, structural strength is enhanced, and the life of the screen 400 is improved.

[0029] In detail, in this embodiment, the discharge end of the extrusion crusher is circular, and the frame 410 of the screen 400 is correspondingly designed as a circular ring structure. The frame 410 has a circular central cavity at its axis, and the screen 420 is disposed in the central cavity and fixedly connected to the frame 410 by bolts. The mounting groove 310 is designed as a semi-circular arc structure corresponding to the circular discharge end of the extrusion crusher, and the fixing member 320 is designed as an annular structure with through holes running vertically through its axis. The through holes are set at the positions of the screen 400 to ensure that the fertilizer particles crushed by the crushing jaw assembly 200 contact the screen 400. The fixing member 320 has a fixing cavity inside and is designed to be openable and closable. The operator opens the fixing member 320 and then fixes the screen 400 in the fixing cavity with bolts, realizing the quick disassembly and replacement of the screen 400.

[0030] In one embodiment, the fixing member 320 includes a first fixing member 321 and a second fixing member 322. The first fixing member 321 and the second fixing member 322 abut against the inner top wall and the inner bottom wall of the mounting groove 310, respectively. The first fixing member 321 and the second fixing member 322 are connected by bolts and the first fixing member 321 and the second fixing member 322 enclose a fixing cavity.

[0031] In this embodiment, the first fixing member 321 is a vertically downward-opening annular groove structure, and the second fixing member 322 is a vertically upward-opening annular groove structure. The first fixing member 321 and the second fixing member 322 are connected by bolts. After the bolt connection, the space formed by the two grooves is the fixing cavity. The screen 400 is disposed in the fixing cavity. The operator fixes the screen 400 to the first fixing member 321 and / or the second fixing member 322 by bolts. It is understood that the bolts used to fix the first fixing member 321 and the second fixing member 322 may include, but are not limited to, countersunk screws, to avoid interference when connecting with the mounting groove 310.

[0032] In one embodiment, the first fixing member 321 further includes a fixing ear 323, which is fixedly disposed on the periphery of the first fixing member 321. The fixing ear 323 extends along the height direction of the first fixing member 321 and abuts against the peripheral outer wall of the second fixing member 322. The periphery of the second fixing member 322 is also provided with a threaded hole, and the fixing ear 323 is threadedly connected to the threaded hole by a bolt.

[0033] In this embodiment, the fixing ear 323 is disposed on one side of the first fixing member 321, and the projected area of ​​the fixing ear 323 is larger than the opening area of ​​the quick-change port 110 on the housing 100. After the first fixing member 321 and the second fixing member 322 are connected by bolts, the operator inserts the fixing member 320 into the mounting groove 310 in the housing 100 along the quick-change port 110. After insertion, the fixing ear 323 is located outside the housing 100 and abuts against the outer surface of the housing 100. The operator can then use bolts to further connect the fixing ear 323 to the housing 100, achieving the technical effect of reinforcing the structure. The inner wall of the fixing ear 323 fits against the outer wall of the housing 100. When the fixing member 320 is inserted along the quick-change port 110...

[0034] In another embodiment, the fixing ear 323 may also be provided with a handle, which is located on the side of the fixing ear 323 away from the housing 100. The handle facilitates the operator to unlock or lock the fixing member 320 with the mounting groove 310 or the housing 100.

[0035] In one embodiment, the quick-change assembly 300 further includes an elastic element 330, which has a ring structure. There are two elastic elements 330, which are respectively disposed on the top periphery of the first fixing member 321 and the bottom periphery of the second fixing member 322. The first fixing member 321 and the second fixing member 322 abut against the mounting groove 310 through the elastic elements 330.

[0036] In this embodiment, two elastic members 330 are respectively bonded and fixed to the top of the first fixing member 321 and the bottom of the second fixing member 322. When the fixing member 320 is inserted into the housing 100 along the opening of the quick-change port 110 and the mounting groove 310, the elastic member 330 abuts against the inner wall of the mounting groove 310 and deforms, so that the fixing member 320 and the mounting groove 310 achieve an interference fit, ensuring the connection stability between the fixing member 320 and the mounting groove 310, while also absorbing the vibration that occurs during the screening process and extending the equipment life.

[0037] In one embodiment, the jaw assembly 200 includes a fixed jaw 210 and a movable jaw assembly 220. The fixed jaw 210 is fixedly disposed on the housing 100, and at least one end of the movable jaw assembly 220 is fixedly disposed on the same side of the housing 100. The horizontal opening of the mounting groove 310 faces the side of the housing 100 near the fixed jaw 210, and the fixed jaw 210 and the mounting groove 310 are spaced apart.

[0038] In this embodiment, the fixed jaw 210 is fixedly disposed within the housing 100, and the movable jaw assembly 220 includes a fixed end and a movable end. The fixed end of the movable jaw assembly 220 is fixedly disposed within the housing 100 on the side away from the fixed jaw 210, and the movable end of the movable jaw assembly 220 is movably connected to the fixed end. The movable end of the movable jaw assembly 220 can move toward the fixed jaw 210. The movement between the fixed jaw 210 and the movable end causes the agglomerated fertilizer particles to be crushed. The horizontal opening of the mounting groove faces the side of the housing 100 where the fixed jaw 210 is installed, thus avoiding interference.

[0039] In one embodiment, the housing 100 further includes a liquid guiding groove 120, which extends vertically downward from the mounting groove 310. There are multiple liquid guiding grooves 120 arranged around the circumference of the housing 100.

[0040] In this embodiment, the liquid guiding channel 120 is disposed on the inner wall of the housing 100 along the periphery of the housing 100. The liquid guiding channel 120 is used to guide the waste liquid generated during the fertilizer crushing and screening process or the wastewater generated when the operator washes the screen 400, and guide the waste liquid to be discharged in the vertical direction of the housing 100, thereby extending the service life of the equipment.

[0041] This utility model discloses a quick-change screen structure for use in a compression crusher. By providing a quick-change component inside the housing, the screen can be quickly disassembled and replaced. The operator fixes the screen in the fixing cavity of the fixing component, and then slides the fixing component into the installation groove along the quick-change opening and fixes it with bolts and elastic elements.
