It mainly improves the physical and chemical properties of the soil and promotes plant growth and the cycle of the soil ecosystem by supplying organic matter.

[0003] In the production and processing of organic fertilizer, grinding is required to fully mix various raw materials and facilitate granulation.

[0004] In related technologies, please refer to Chinese Patent No. 201921073376.X, which specifically discloses an integrated high-speed crushing and screening machine for organic fertilizer. This integrated high-speed crushing and screening machine for organic fertilizer has advantages such as more thorough and faster crushing.

[0005] The applicant discovered that when the aforementioned high-speed integrated crushing and screening machine for organic fertilizer is crushing organic fertilizer, both the inner and outer crushing cylinders are rotating. At the same time, the feed pipe is located above the outer crushing cylinder. When the outer crushing cylinder rotates, the feed pipe rotates downwards, causing organic fertilizer to leak out through the feed pipe, affecting the crushing effect of the organic fertilizer. Furthermore, the feed pipe rotates with the outer crushing cylinder, making continuous feeding and crushing operations impossible and reducing work efficiency.

[0006] In view of this, an integrated grinding and screening machine is proposed. Utility Model Content

A motor is fixedly connected to the top of the grinding barrel and connected to the rotating shaft. A crushing blade, a fixing frame, and a stirring frame are fixedly connected to the rotating shaft. A positioning sleeve is provided below the rotating shaft. A grinding roller is rotatably connected between the positioning sleeve and the fixing frame and is in contact with the top of the screen. A material collection hood is provided below the inner wall of the grinding barrel.

[0010] In a preferred embodiment, the bottom of the collection bucket is provided with casters with braking devices, and an inclined discharge pipe is connected through the lower right side of the collection bucket.

[0011] In a preferred embodiment, the outer diameter of the limiting ring and the screen are the same, and the screen and the top of the collection bucket are located on the same horizontal plane.

[0012] In a preferred embodiment, the lower inner wall of the collection bucket has an inclined structure, and the left sides of the collection bucket and the grinding bucket are connected by a hinge.

[0013] In a preferred embodiment, the pulverizing blade is located above the fixing frame and the stirring frame, and the fixing frame is arranged opposite to the stirring frame.

[0014] In a preferred embodiment, the fixing frame has an L-shaped structure, and the positioning sleeve is installed below the rotating shaft by a second bolt.

[0015] In a preferred embodiment, the screen and the limiting ring are installed by a second bolt, and the upper two sides of the grinding barrel are connected through a feed hopper.
