During the rotation of the raw material crushing piece 8, the inclined surface on one side will first contact the large piece of raw material, and then the raw material crushing piece 8 will push the large piece of raw material to move until the large piece of raw material contacts the cylindrical rod at the top of the raw material support plate 5. At this time, the large piece of raw material cannot be displaced, and the raw material crushing piece 8 continues to rotate to squeeze and crush the large piece of raw material; a discharge baffle 9 is installed on the right side of the bottom of the mixing barrel 1. After the raw materials are mixed, the discharge baffle 9 at the bottom of the mixing barrel 1 can be removed, and then the mixed biological organic fertilizer can be discharged outward.

[0030] In the embodiment of the present disclosure, Figure 3 As shown, the top view of the raw material crushing piece 8 is a fan-shaped piece, and the raw material crushing piece 8 can rotate in the annular open groove on the raw material support plate 5. During the rotation of the raw material crushing piece 8, the inclined surface on one side thereof will first contact the large piece of raw material, and then the raw material crushing piece 8 will push the large piece of raw material to move until the large piece of raw material contacts the cylindrical rod on the top of the raw material support plate 5. At this time, the large piece of raw material cannot be displaced, and the raw material crushing piece 8 continues to rotate to squeeze and crush the large piece of raw material.

[0031] In the embodiment of the present disclosure, Figure 1 and Figure 3-Figure 5 As shown, the raw material support plate 5 is provided with three annular opening grooves running through the upper and lower parts, and the three annular opening grooves are arranged at equal distances. The crushed raw materials will fall downward through the annular opening grooves on the raw material support plate 5 into the cavity in the mixing barrel 1 for stirring and mixing.

[0032] In the embodiment of the present disclosure, as shown in FIG Figure 1 and Figure 4-Figure 6 As shown, two inclined surfaces are provided on the outer side of the raw material crushing piece 8. The side view of the raw material crushing piece 8 is an inverted trapezoidal structure as a whole. During the rotation of the raw material crushing piece 8, the inclined surface on one side will first contact the large piece of raw material, and then the raw material crushing piece 8 will push the large piece of raw material to move until the large piece of raw material contacts the cylindrical rod on the top of the raw material support plate 5. At this time, the large piece of raw material cannot be displaced, and the raw material crushing piece 8 continues to rotate to squeeze and crush the large piece of raw material.

[0033] In the embodiment of the present disclosure, Figure 1 and Figure 3-Figure 5 As shown, six groups of thirty-six cylindrical rods are arranged in a ring on the top of the raw material support plate 5, and the six groups of cylindrical rods are respectively located at the top edge positions of the three annular opening grooves on the raw material support plate 5. During the rotation of the raw material crushing piece 8, the inclined surface on one side will first contact the large piece of raw material, and then the raw material crushing piece 8 will push the large piece of raw material to move until the large piece of raw material contacts the cylindrical rods on the top of the raw material support plate 5. At this time, the large piece of raw material cannot be displaced, and the raw material crushing piece 8 continues to rotate to squeeze and crush the large piece of raw material.

[0034] In the embodiment of the present disclosure, Figure 1 and Figure 3-Figure 6 As shown, a horizontal rectangular plate is provided at the top of the stirring shaft 6, and six raw material crushing pieces 8 are symmetrically arranged on the top of the rectangular plate at the top of the stirring shaft 6. The six raw material crushing pieces 8 also pass through the annular opening groove on the raw material support plate 5 in groups of two and extend upward. When the motor 3 rotates, the stirring teeth 7 will be driven to rotate synchronously through the stirring shaft 6. At the same time, the stirring shaft 6 will also drive the six raw material crushing pieces 8 to rotate continuously in the annular opening groove on the raw material support plate 5, so that large pieces of raw materials can be crushed.

[0035] Example 2, based on Example 1, Figures 1-6 As shown, the height of the cylindrical rod at the top of the raw material support plate 5 is two-thirds of the height of the raw material crushing piece 8, and the top surface of the raw material crushing piece 8 is located below the bottom surface of the horizontal plate above the upper support plate 4. During the rotation of the raw material crushing piece 8, the inclined surface on one side will first contact the large piece of raw material, and then the raw material crushing piece 8 will push the large piece of raw material to move until the large piece of raw material contacts the cylindrical rod at the top of the raw material support plate 5. At this time, the large piece of raw material cannot be displaced, and the raw material crushing piece 8 continues to rotate to squeeze and crush the large piece of raw material. Therefore, the cylindrical rod at the top of the raw material support plate 5 can effectively block the large piece of raw material, and the raw material crushing piece 8 will not collide with the upper support plate 4 when rotating.

[0036] The working principle of this embodiment is as follows: when the device is needed to stir and mix the raw materials of biological organic fertilizer, the device is first placed on the ground through the support of the base 2, and the motor 3 is connected to the external controller and the power supply. When mixing, the motor 3 is powered on. When the motor 3 rotates, the stirring gear 7 is driven to rotate synchronously through the stirring shaft 6. At the same time, the stirring shaft 6 also drives the six raw material crushing pieces 8 to rotate continuously in the annular opening groove on the raw material support plate 5. In this process, the upper support plate 4 can stably support the raw material support plate 5. Then, the raw materials to be mixed can be placed on the top of the raw material support plate 5, and the raw material crushing pieces 8 are During the rotation process, the inclined surface on one side will first contact the bulk of raw materials, and then the raw material crushing piece 8 will push the bulk of raw materials to move until the bulk of raw materials contacts the cylindrical rod on the top of the raw material support plate 5. At this time, the bulk of raw materials cannot be displaced, and the raw material crushing piece 8 continues to rotate to squeeze and crush the bulk of raw materials. The crushed raw materials will fall down into the cavity in the mixing barrel 1 through the annular opening groove on the raw material support plate 5, and then the stirring teeth 7 can mix the raw materials. After the raw materials are mixed, the discharge baffle 9 at the bottom of the mixing barrel 1 can be removed, and then the mixed biological organic fertilizer can be discharged outward.
