[0022] At the middle position at the top of the crushing bin 1, a feed inlet 101 is fixedly connected. At the bottom ends on both sides inside the feed inlet 101, guide blocks 102 are fixedly connected. On one side outside the crushing bin 1, a viewing window 103 is installed. At the middle position at the bottom of the crushing bin 1, a discharge outlet 104 is installed. The guide blocks 102 provided inside the feed inlet 101 can conduct the guiding work of the fertilizer raw materials, and the discharge work of the fertilizer raw materials after crushing can be carried out through the discharge outlet 104.

[0023] In the driving mechanism 3, a first motor 301 installed on one side inside the installation bin 2 is included. At the output shaft end of the first motor 301, a first gear 302 is installed. On one side of the first gear 302, a second gear 303 rotating inside the installation bin 2 is meshed and connected. On one side of the first gear 302, a first connecting block 304 is fixedly connected. When the first motor 301 is started, it can drive the first gear 302 to rotate. At the same time, the first gear 302 can push the second gear 303 to rotate. And the first gear 302 and the second gear 303 can respectively drive the crushing roller 4 on one side through the first connecting block 304 to rotate, and carry out the crushing work on the fertilizer raw materials falling inside the feed inlet 101.

[0024] In the rotating mechanism 7, a driving roller 701 installed at the middle position inside the grinding bin 6 is included. At the two sides at the top of the driving roller 701, push plates 702 are fixedly connected. Inside one side of the push plates 702, through grooves 703 are provided. At the middle position at the bottom end of the driving roller 701, a pressure roller 704 is installed. On one side of the driving roller 701, a servo motor is installed. By starting the motor, it can drive the driving roller 701 to rotate, and make the driving roller 701 drive the push plates 702 and the pressure roller 704 to rotate. At the same time, the through grooves 703 provided on the push plates 702 facilitate the crushed fertilizer raw materials to fall into the bottom end inside the grinding bin 6.

[0025] The lifting mechanism 8 includes a lifting bin 801 on both sides inside the crushing bin 1 and communicating with the first guiding groove 601. Inside the bottom end of the lifting bin 801, a second motor 802 is installed. At the output shaft end of the second motor 802, an auger 803 is installed.

[0026] Embodiment 2, the main difference from Embodiment 1 lies in:

[0027] In a raw material crushing device for fertilizer preparation, the limiting mechanism 5 includes a cross groove 401 provided at the middle positions on both sides of the crushing roller 4. At both ends on the outer side of the installation bin 2, screw rods 501 are threadedly connected. On one side of the screw rod 501, a movable disk 502 is rotatably connected. At the middle position on one side of the movable disk 502, a connecting rod 503 is fixedly connected. On one side of the connecting rod 503, a second connecting block 504 inserted into the cross groove 401 is fixedly connected. When the screw rod 501 rotates, it can drive the through groove 703 and the second connecting block 504 to move through the push plate 702. At the same time, since the screw rod 501 and the movable disk 502 are rotatably connected, the crushing roller 4 drives the connecting rod 503 and the movable disk 502 to rotate through the second connecting block 504, which will not affect the rotation of the screw rod 501. At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0028] When the embodiment of the present application is in use: Pour the fertilizer raw materials to be crushed into the inside of the feed inlet 101. At this time, through the guiding of the guiding block 102, the fertilizer raw materials can fall onto the top of the crushing roller 4. By starting the first motor 301, the first gear 302 can be driven to rotate. At the same time, the first gear 302 can push the second gear 303 on one side to rotate. At this time, the first gear 302 and the second gear 303 can respectively drive the crushing roller 4 to rotate and perform the crushing work on the fertilizer raw materials. The crushed fertilizer raw materials can fall to the bottom end inside the grinding bin 6 due to gravity. At this time, the driving roller 701 drives the pressing roller 704 to rotate at the bottom end of the grinding bin 6, and can perform secondary grinding on the fertilizer raw materials, and make the fertilizer raw materials fall into the discharge port 104 through the sieve plate 602 for discharging. At the same time, the unground fertilizer raw materials are driven by the driving roller 701 to drive the push plate 702 to rotate, so that the push plate 702 can push the fertilizer raw materials on the top of the sieve plate 602 to enter the inside of the lifting bin 801 from the first guiding groove 601, and the fertilizer raw materials are input into the feed inlet 101 through the auger 803 from the second guiding groove 804 for secondary crushing work.
