Description

Technical Field

[0001] The invention relates to the technical field of seaweed fertilizer preparation, in particular to a kelp crusher for preparing seaweed fertilizer with the function of improving soil and increasing efficiency. Background Art

[0002] In the process of preparing seaweed fertilizer, the kelp needs to be crushed first, and the kelp is crushed into fine particles so as to be used in the preparation of seaweed fertilizer. The main structure of the existing kelp crusher for preparing seaweed fertilizer with soil improvement and efficiency enhancement includes two toothed rotating columns installed side by side, a driving motor for driving, and a linkage structure that links the two toothed rotating columns and the rotor end of the driving motor. When working, the driving motor generates a rotational driving function to drive the linkage structure to rotate. When the linkage structure rotates, it can make the two toothed rotating columns produce reverse rotational motion toward the symmetry plane, and then the dried kelp is placed on the occlusal surface of the two toothed rotating columns. Under the rotation action of the two toothed rotating columns, the kelp is crushed.

[0003] However, when the above-mentioned kelp crusher for preparing seaweed fertilizer with the effect of improving soil and enhancing efficiency is actually working, since there is a large bite gap between the teeth in the two tooth rotating columns when they bite, therefore, when it crushes the kelp, the crushed kelp is only divided into smaller flake structures, and the volume after crushing is difficult to meet the requirements of fine particles. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a kelp crusher for preparing seaweed fertilizer with the function of improving soil and enhancing efficiency. The rotating spiral blade structure can produce a downward pressure-type conveying phenomenon on the kelp, and the whole kelp can be first cut into smaller sheet structures under the phenomenon of rotating compression of the spiral blades, and then the kelp with smaller sheet structures can be squeezed and rotated through a conical grinding space to form fine sheet structures, and finally under the action of extrusion and grinding, fine particles that meet the requirements are formed, thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above object, the present invention provides the following technical solution: A kelp crusher for preparing seaweed fertilizer with the function of improving soil and increasing efficiency, comprising a vertical hollow housing, a horizontal support plate arranged at the bottom of the circumferential surface of the vertical hollow housing, longitudinal support rods installed at the edges of the lower surface of the horizontal support plate, a main mounting plate arranged at the bottom end of the longitudinal support rods and used for fixed installation, an inverted drive motor installed at the top end of the vertical hollow housing, a cylindrical hollow cavity arranged in the upper section of the vertical hollow housing, and an injection port for horizontally injecting kelp bodies into the cylindrical hollow cavity. A conical space with an open bottom end is arranged at the bottom end of the cylindrical hollow cavity. The rotor end of the drive motor extends into the interior of the cylindrical hollow cavity, and a spiral conical crushing structure that rotates with it is installed at the bottom end. The bottom end of the vertical hollow housing is installed with an extrusion rotary grinding structure that can rotate relative to it and generates a rated pressure value downward on the lower surface under a rated hydraulic pressure. A bottom grinding structure that is located directly below the extrusion rotary grinding structure and cooperates with the extrusion rotary grinding structure to generate a rotary grinding phenomenon is installed between the rod bodies of the longitudinal support rods. The injection port is located in the longitudinal central area of the cylindrical hollow cavity. The top end of the conical space has the same structural radius as the bottom end of the cylindrical hollow cavity, and the structural radius gradually decreases from top to bottom.

[0008] Through the above technical solution: The rotating spiral blade structure can generate a downward pressure conveying phenomenon on the kelp, and the whole kelp can be first cut into smaller sheet-like structures under the rotation and compression of the spiral blades, and then the smaller sheet-like kelp structures are extruded and rotated in the conical grinding space to form fine sheet-like structures. Finally, under the action of extrusion and grinding, fine particles that meet the requirements are formed.

[0009] Preferably, the spiral conical crushing structure includes a cylindrical rotating body located in the central area of the cylindrical hollow cavity. An axial body installation groove for fixedly installing the rotor of the drive motor is arranged inside the upper end surface of the cylindrical rotating body. A spiral blade structure is arranged on the circumferential surface of the cylindrical rotating body. The bottom end of the cylindrical rotating body is provided with a conical rotating body that is an integral structure and is located inside the conical space. A conical convex guiding structure is arranged at the intersection of the conical rotating body and the cylindrical rotating body. The gap between the edge of the conical rotating body and the edge of the conical space gradually decreases from top to bottom. There is a gap between the edge of the spiral blade structure and the inner wall of the circumferential surface of the cylindrical hollow cavity, but the size of this gap is not large enough to allow the kelp to move up and down, and the edge of the spiral blade structure is a pointed structure. The structural radius from the upper surface of the cylindrical rotating body to the conical convex guiding structure part increases from small to large, and the structural radius from the conical convex guiding structure to the lower surface of the cylindrical rotating body decreases from large to small. The edge of the conical convex guiding structure is located at the central part between the cylindrical rotating body and the inner wall of the circumferential surface of the cylindrical hollow cavity.

[0010] Through the above technical scheme: when the cylindrical rotating body rotates with the driving motor, by controlling the rotation direction of the driving motor, the spiral blade structure is controlled to generate a downward conveying trend when rotating. At this time, when the kelp is laterally introduced near the spiral blade structure, the spiral blade structure will cut the kelp into smaller strip structures due to its tip structure at the edge, and move downward under the pressure of the spiral blade structure. When the kelp is squeezed to the vicinity of the conical protrusion guide structure, due to the stacking effect, it will move downward along the gap around it through its guide. When the kelp moves to the lower structure of the conical rotating body, due to its rotation effect, it will produce rotational grinding on the accumulated kelp. Since the structural radius from the conical protrusion guide structure to the lower surface of the cylindrical rotating body is greatly reduced, the grinding gap is gradually reduced, and the kelp is transformed into a small flake structure.

[0011] Preferably, the extrusion rotary grinding structure includes a hollow rotating shaft whose top end is rotatably mounted on the bottom end of a vertical hollow shell body through a bearing, a pulley structure for linkage with an external belt is arranged in the middle of the circumferential surface of the hollow rotating shaft, a material conveying hole whose top end is connected to the bottom end of the conical space and whose bottom end is open is arranged in the center of the hollow rotating shaft, a disc-shaped hollow body whose lower surface is flush with the bottom end is arranged at the bottom end of the hollow rotating shaft, and an annular pressure chamber with an open bottom end is arranged on the periphery of the hollow rotating shaft, an annular rubber sheet with a downwardly protruding bottom end is embedded in the bottom end of the disc-shaped hollow body, coolant is injected into the interior of the annular pressure chamber, and the hydraulic strength of the coolant on the annular rubber sheet is sufficient to make the bottom surface of the annular rubber sheet and the upper surface of the bottom grinding structure conflict with each other in the form of a certain pressure value, the annular rubber sheet is an annular body structure made of elastic and wear-resistant material, and the center of the annular body is a through hole structure.

[0012] Through the above technical scheme: when the kelp moves to the inside of the annular rubber sheet under the action of pressure from above, the accumulated small kelp pieces enter between the annular rubber sheet and the grinding disc under the action of pressure. Since the bottom surface of the annular rubber sheet and the upper surface of the grinding disc conflict with each other in the form of a certain pressure value, when the external motor and belt make the hollow rotating shaft rotate in conjunction, the annular rubber sheet will be driven to rotate, and the annular rubber sheet will produce a resistance-type grinding function on the small kelp pieces, generating downward pressure, thereby grinding the small kelp pieces. At the same time, since the interior of the annular pressure chamber is filled with coolant, the negative impact of excessive component temperature caused by grinding on the kelp can be reduced.

[0013] Preferably, the bottom grinding structure includes a grinding disc located directly below the annular rubber sheet, a downwardly protruding cylindrical protrusion is provided at the center of the lower surface of the grinding disc, a transverse support rod for fixedly connecting to each longitudinal support rod is provided on the circumferential surface of the cylindrical protrusion, and a plurality of upwardly protruding hemispherical structures are provided on the upper end surface of the grinding disc.

[0014] Through the above technical solution: Since the grinding disc is fixedly connected, when the grinding disc rotates, relative rotation occurs between the two, causing the kelp to be squeezed and ground to form fine particles while rotating on the upper surface and remaining stationary on the lower surface. At the same time, due to the material properties of the annular rubber sheet, the kelp has a high degree of curvature on the grinding surface, resulting in a stronger grinding effect.

[0015] Compared with the prior art, the present invention provides a kelp crusher for preparing seaweed fertilizer with the effect of improving soil and increasing efficiency, and has the following beneficial effects:

[0016] The kelp crusher for preparing seaweed fertilizer with the effect of improving soil and increasing efficiency can generate a downward pressure conveying phenomenon on the kelp through the rotating spiral blade structure, and can first cut the whole kelp into smaller sheet-like structures under the phenomenon of spiral blade rotation and compression, and then squeeze and rotate the smaller sheet-like kelp structures through the conical grinding space to form fine sheet-like structures, and finally form fine particles meeting the requirements under the action of extrusion and grinding.

The gap decreases gradually from top to bottom, and there is a gap between the edge of the spiral blade structure 93 and the inner wall of the circumferential surface of the cylindrical hollow cavity 5, but the size of the gap is not enough to allow the kelp to move up and down, and the edge of the spiral blade structure 93 is a pointed structure. The structural radius from the upper surface of the cylindrical rotating body 91 to the conical protrusion guide structure 95 changes from small to large, and the structural radius from the conical protrusion guide structure 95 to the lower surface of the cylindrical rotating body 91 changes from large to small. The edge of the conical protrusion guide structure 95 is located at the center between the cylindrical rotating body 91 and the inner wall of the circumferential surface of the cylindrical hollow cavity 5.

[0027] See also Figure 5 The extrusion rotary grinding structure 10 includes a hollow rotating shaft 101 whose top end is rotatably mounted on the bottom end of the vertical hollow shell 1 through a bearing, a pulley structure 102 for linkage with an external belt is arranged in the middle of the circumferential surface of the hollow rotating shaft 101, a material conveying hole 104 whose top end is connected to the bottom end of the conical space 8 and whose bottom end is open is arranged in the center of the hollow rotating shaft 101, and a disc-shaped hollow body 103 whose lower surface is flush with the hollow rotating shaft 101 is arranged at the bottom end of the hollow rotating shaft 101, and the disc-shaped hollow body 103 is arranged at the hollow rotating shaft An annular pressure chamber 105 with an opening at the bottom is arranged on the periphery of 101, and an annular rubber sheet 106 with a downwardly protruding bottom end is embedded in the bottom end of the disc-shaped hollow body 103. Coolant is injected into the interior of the annular pressure chamber 105, and the hydraulic strength of the coolant on the annular rubber sheet 106 is sufficient to make the bottom surface of the annular rubber sheet 106 and the upper surface of the bottom grinding structure 11 contact each other in the form of a certain pressure value. The annular rubber sheet 106 is an annular body structure made of elastic and wear-resistant material, and the center of the annular body is a through-hole structure.

[0028] See also Figure 6 The bottom grinding structure 11 includes a grinding disc 111 located directly below the annular rubber sheet 106, a downwardly protruding cylindrical protrusion column 112 is arranged at the center of the lower surface of the grinding disc 111, and a transverse support rod 113 for fixedly connecting with each longitudinal support rod 3 is arranged on the circumferential surface of the cylindrical protrusion column 112, and a plurality of upwardly protruding hemispherical structures 114 are arranged on the upper end surface of the grinding disc 111.

[0029] When in use, first, a driving motor with a pulley installed at the rotor end is selected, and then the driving motor is fixed, and the pulley and the pulley structure 102 are linked by a belt, and then the motor and the driving motor 6 are turned on at the same time, and then the dried kelp is introduced into the cylindrical hollow cavity 5 through the injection port 7. When the cylindrical rotating body 91 rotates with the driving motor 6, by controlling the rotation direction of the driving motor 6, the spiral blade structure 93 is controlled to rotate to generate a downward conveying trend. At this time, when the kelp is introduced laterally to the vicinity of the spiral blade structure 93, the spiral blade structure 93 will cut the kelp into smaller strip structures due to its tip structure at the edge, and move downward under the pressure of the spiral blade structure 93. When the kelp is squeezed to the vicinity of the conical protrusion guide structure 95, due to the stacking effect, it will move downward through its guide along the gap around it. When the kelp moves to the lower section structure of the conical rotating body 94, due to its rotation effect, the accumulated kelp will be rotary polished. Due to the conical protrusion guide structure 95 to the structural semi-circular structure of the lower surface of the cylindrical rotating body 91, the kelp will be rotated and polished. The diameter of the annular rubber sheet 106 changes from large to small, so the grinding gap is gradually reduced, and the kelp is transformed into a small sheet structure. Under the pressure from above, the accumulated kelp continues to move downward. When the kelp moves to the inside of the annular rubber sheet 106, the accumulated small kelp pieces enter between the annular rubber sheet 106 and the grinding disc 111 under the pressure. Since the bottom surface of the annular rubber sheet 106 and the upper surface of the grinding disc 111 are in contact with each other in the form of a certain pressure value, when the external motor and belt make the hollow rotating shaft 101 rotate in conjunction, it will drive The annular rubber sheet 106 rotates, and the annular rubber sheet 106 will have a resistance-type grinding function on the small kelp pieces, generating downward pressure, thereby grinding the small kelp pieces. Since the grinding disc 111 is fixedly connected, when the grinding disc 111 rotates, the two rotate relative to each other, which will cause the kelp to be squeezed and ground while the upper surface rotates and the lower surface is stationary, forming fine particles. At the same time, the rotation of the annular rubber sheet 106 will drive the kelp to move toward the periphery, and finally be discharged to the surrounding along its edge.
