DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is achieved by performing activities on connecting parts such as hinges, pins and short shafts.

[0020] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0021] The following is combined with Figure 1-6This embodiment describes a raw material grinding device, comprising: a hopper 1, a feed cylinder 2 connected to the lower end of the hopper 1, a conical cylinder 3 connected to the lower end of the feed cylinder 2, a conical block 4 provided with equal gaps inside the conical cylinder 3, an input shaft 5 connected to the axis of the lower surface of the conical block 4, the input shaft 5 rotatably connected to the inside of a bearing bracket 6, the bearing bracket 6 connected to the inner wall of the lower chamber of the conical cylinder 3, and a conveying spiral blade 7 connected to the axis of the upper end of the conical block 4;

[0022] The chopped medicinal materials are placed in the hopper 1, and the input shaft 5 is turned on to drive the cone block 4 to rotate. The cone block 4 drives the spiral blade 7 to rotate to transport the medicinal materials in the hopper 1 downward. The spiral blade 7 squeezes the chopped medicinal materials into the gap between the cone block 4 and the cone cylinder 3. The medicinal materials are ground into powder by the cone block 4 and the cone cylinder 3. Under the push of the subsequent medicinal materials, the ground materials are discharged along the inclined surface through the gap at the bottom of the cone block 4 and the cone cylinder 3, completing the grinding.

[0023] An inclined chute 8 is provided on the outer surface of the cone block 4. The inclination direction of the chute 8 on the cone block 4 is consistent with the spiral direction of the conveying spiral blade 7. A clearing slide 9 is slidably connected in the chute 8. The clearing slide 9 can be completely received in the chute 8 and its outer surface coincides with the outer surface of the cone block 4. The sliding distance of the clearing slide 9 is adjusted by an adjustment mechanism 10.

[0024] Since the clearing slide 9 can be completely accommodated in the chute 8 and its outer surface coincides with the outer surface of the cone block 4, it will not affect the grinding operation. When the raw material is blocked in the grinding gap due to humid air or high moisture content of the material, the clearing slide 9 is controlled to slide out by the adjustment mechanism 10, and the blocked material is discharged along the inclined surface of the rotating clearing slide 9 without the need to disassemble for clearing.

[0025] The adjustment mechanism 10 includes an adjustment slot 101, an adjustment hole 102 is opened between the adjustment slot 101 and the slide slot 8, a partition 103 is connected to the adjustment slot 101 and the adjustment hole 102, a threaded shaft 104 is rotatably connected in the partition 103, the threaded shaft 104 is threadedly connected in the threaded sleeve 105, and the threaded sleeve 105 is connected to the clearing slide 9;

[0026] During adjustment, the threaded shaft 104 is rotated and the threaded shaft 104 is axially limited by the partition 103. The partition 103 drives the clearing slide 9 to slide in the slide groove 8 through the threaded sleeve 105 connected by thread, thereby completing the adjustment.

[0027] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
