Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0021] Refer toFigures 1-4 , a compound fertilizer raw material crushing device, including a crushing barrel 1, a feed hopper 2, a stirring device 3, a stirring motor 31, a transmission chamber 32, a first pulley 33, a second pulley 34, a transmission belt 35, a stirring shaft 36, stirring blades 37, a support frame 4, a reciprocating device 5, a fixed block 51, a movable rod 52, a motor 53, a bottom block 54, a limiting block 55, a turntable 56, a convex block 57, a screen grid frame 6, a through groove 7, a spring frame 8, a fixed rod 9, a screen 10 and a discharge pipe 11. The top of the crushing barrel 1 is equipped with a feed hopper 2, and the front of the crushing barrel 1 is equipped with a stirring device 3. The bottom of the crushing barrel 1 is equipped with a support frame 4, and through grooves 7 are opened on the outer side of the support frame 4. Both ends of the inner side of the through groove 7 are equipped with spring frames 8, and a fixed rod 9 is installed inside the through groove 7. A screen grid frame 6 is connected inside the through groove 7, and a screen 10 is installed inside the screen grid frame 6. The bottom of the crushing barrel 1 is equipped with a discharge pipe 11.

[0022] Furthermore, the front of the crushing barrel 1 is connected to a stirring motor 31, and the top of the stirring motor 31 penetrates through the transmission chamber 32 and is connected to the first pulley 33 inside. The outer side of the first pulley 33 is equipped with a transmission belt 35, and the inner side of the transmission belt 35 is connected to the second pulley 34. The bottom of the second pulley 34 is equipped with a stirring shaft 36, and the bottom of the stirring shaft 36 is equipped with stirring blades 37. Start the stirring motor 31. The first pulley 33 is driven to rotate by the stirring motor 31, and the first pulley 33 will drive the second pulley 34 to rotate through the transmission belt 35, so that the stirring shaft 36 at the bottom of the second pulley 34 rotates together. The stirring blades 37 on the outer side of the stirring shaft 36 will then crush the compound fertilizer raw materials.

[0023] Furthermore, the inside of the reciprocating device 5 includes a fixed block 51 connected to the outer side of the support frame 4. The inside of the fixed block 51 is movably connected to a movable rod 52. A limiting block 55 is installed at the top of the movable rod 52, and a bottom block 54 is installed at the bottom of the movable rod 52. A convex block 57 is arranged directly below the bottom block 54, and a turntable 56 is installed on one side of the convex block 57. A motor 53 is connected to one side of the turntable 56. Start the motor 53. The turntable 56 at one end of the motor 53 will rotate, and the turntable 56 will drive the convex block 57 to rotate together, so that the convex block 57 contacts the upper bottom block 54 at a certain frequency. The movable rod 52 at the top of the bottom block 54 will move up and down in the fixed block 51. When the movable rod 52 moves up and down, it will hit the upper screen grid frame 6, causing the screen grid frame 6 to vibrate and screen the compound fertilizer raw materials inside the screen 10, screening out the compound fertilizer raw materials with unqualified crushing.

[0024] Furthermore, the convex block 57 forms a rotating structure with the turntable 56 and the motor 53, and the convex block 57 is fixedly installed on one side of the turntable 56.

[0025] Further, the stirring blade 37 forms a rotating structure with the second pulley 34 through the stirring shaft 36, and the second pulley 34 is connected to the first pulley 33 through the transmission belt 35. Multiple groups of stirring blades 37 are evenly distributed outside the stirring shaft 36.

[0026] Further, the screen frame 6 is movably connected to the fixed rod 9. When the screen frame 6 vibrates, there will be no large horizontal offset.

[0027] Working principle: During use, first, the compound fertilizer raw materials are placed into the crushing barrel 1 by the operator through the feed hopper 2. After placing, the stirring motor 31 is started. The first pulley 33 is driven to rotate by the stirring motor 31. The first pulley 33 will drive the second pulley 34 to rotate through the transmission belt 35, so that the stirring shaft 36 at the bottom of the second pulley 34 rotates together. The stirring blades 37 outside the stirring shaft 36 will crush the compound fertilizer raw materials. After crushing, the discharge pipe 11 at the bottom of the crushing barrel 1 is opened, so that the crushed compound fertilizer raw materials are discharged to the top of the screen 10. At the same time, the operator starts the motor 53. The turntable 56 at one end of the motor 53 will rotate. The turntable 56 will drive the convex block 57 to rotate together, so that the convex block 57 contacts the upper bottom block 54 at a certain frequency. The movable rod 52 at the top of the bottom block 54 will move up and down in the fixed block 51. When the movable rod 52 moves up and down, it will hit the upper screen frame 6, so that the screen frame 6 vibrates, and the compound fertilizer raw materials inside the screen 10 are screened. The unqualified crushed compound fertilizer raw materials are screened out. When the screen frame 6 vibrates, it will hit the spring frame 8 to prevent the screen frame 6 from hitting the inside of the through groove 7 and prevent a large noise from being generated.
