Description

Technical Field

[0001] This utility model belongs to the field of crusher technology, and in particular relates to a cutter roller structure for a plant crusher. Background Technology

[0002] In fields such as plant processing, plant pulverization is often required. Existing plant pulverizing equipment suffers from problems such as poor pulverization efficiency, complex structure, and susceptibility to material entanglement. For example, some equipment fails to pulverize plant materials to the required particle size, affecting subsequent processing; the blades and internal structures of some equipment are poorly designed, easily causing material blockage and entanglement. Therefore, a new plant pulverizer cutter roller structure is needed to solve these problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a blade roller structure for a plant crusher. The structure comprises a housing, inside which are a feeding bin and a storage chamber. A main roller is installed inside the feeding bin, and multiple blade holder grooves are evenly distributed on the surface of the main roller. Each blade holder groove contains a stepped blade holder, and multiple cutting blades are evenly arranged on each stepped blade holder.

[0004] In one example, a feeding port is provided at the top of the feeding bin, and cutting grooves corresponding to the cutting blade are evenly distributed on the inner walls of both sides of the feeding bin, and the size is adapted to the cutting blade. The corresponding position without the blade holder is a smooth surface.

[0005] In one example, the main roller is cylindrical and has connecting shafts at both ends. Each stepped tool holder is divided into two steps, with the bottom rectangular step being smaller than the top arc-shaped step and matching the shape of the tool holder groove.

[0006] In one example, each cutter is crescent-shaped with the blade on the inside.

[0007] In one example, the storage chamber is an inverted trapezoid with the upper end larger than the lower end. Multiple vertically upright rotating cutter shafts are located at the center of the upper and lower parts. Each rotating cutter shaft has a rotating cutter holder fixed at its upper end. Each rotating cutter holder is equipped with multiple 90-degree bent crushing blades, and adjacent crushing blades are in opposite directions but have the same blade direction.

[0008] In one example, a removable filter screen is located at the lower end of the storage chamber, directly below the rotating blade shaft and close to the pulverizer.

[0009] In one example, each cutting blade corresponds to a cutting groove, and the bottom of the housing has a discharge port.

[0010] In one example, each stepped tool holder is fixed in the corresponding cutting slot by multiple screws, and the surface of each stepped tool holder is flush with the surface of the main roller.

[0011] The plant crusher cutter roller structure proposed in this utility model can bring the following beneficial effects:

[0012] 1. This utility model, through its unique cutter roller structure design, namely the stepped cutter holder and cutting blade on the main roller body, combined with the cutting groove on the inner wall of the feeding bin, can initially cut plant materials into small segments, thereby improving the efficiency and uniformity of crushing.

[0013] 2. The design of the rotating blade shaft and crushing blade in the storage chamber is similar to that of a high-speed blender. It performs secondary crushing on the initially crushed material, further ensuring the crushing effect and enabling the material to reach a finer particle size to meet various processing needs.

[0014] 3. The detachable filter screen is easy to clean and replace, and its reasonable positioning fully utilizes the airflow generated by the rotating blades to further pulverize incompletely crushed materials, reducing material waste and improving resource utilization. The entire device has a compact structure, with all components working in tandem to improve the efficiency of plant pulverization while also facilitating maintenance and operation.

[0015] 4. By using a cutting blade in conjunction with the cutting grooves on the inner wall of the feeding hopper, the material is cut into multiple small segments, which can effectively prevent the material from getting tangled in the blade. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same solution or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.

[0032] like Figures 1-9 As shown in the figure, an embodiment of this utility model proposes a plant crusher cutter roller structure, which includes a shell 1, and a feeding bin 3 and a storage chamber 9 are arranged inside the shell 1. The feeding bin 3 is semi-circular in shape, and a feeding port 2 is provided at the upper end of the feeding bin 3 for feeding plant materials that need to be crushed.

[0033] A main roller body 4 is installed inside the feeding bin 3. The main roller body 4 is cylindrical in shape, with connecting shafts at both ends. It is installed in the feeding bin 3 via the connecting shafts and can rotate. Multiple tool holder slots 6 are evenly distributed on the surface of the main roller body 4, and stepped tool holders 5 are fixedly installed in the tool holder slots 6. The stepped tool holder 5 is divided into two steps. The bottom step is rectangular and smaller than the top step, while the surface of the top step is curved. The shape of the tool holder slots 6 on the roller matches the shape of the stepped tool holder 5. The stepped tool holder 5 is fixed in the tool holder slots 6 with multiple screws. After fixing, the surface of the stepped tool holder 5 and the surface of the main roller body 4 are on the same plane. Each stepped tool holder 5 is equipped with multiple cutting blades 7. The cutting blades 7 are crescent-shaped, with the inner side of the crescent being the cutting edge. The cutting blades 7 on each stepped tool holder 5 are evenly distributed, with consistent distance between the blades, and a certain distance is maintained between each stepped tool holder 5.

[0034] Multiple cutting grooves 8 are evenly distributed on the inner walls of both sides of the feeding bin 3. Each cutting groove 8 corresponds to a cutting blade 7 on the blade holder. The dimensions of the cutting groove 8 (groove width and depth) and the dimensions of the cutting blade 7 (blade thickness and length) are matched. When the main roller 4 rotates, each cutting blade 7 will smoothly pass through the corresponding cutting groove 8 without collision or interference. The cutting blade 7 and the cutting groove 8 form a cutting feature, which can effectively cut off the material. The inner walls of the feeding bin 3 are smooth surfaces where there are no stepped blade holders 5.

[0035] The lower end of the feeding bin 3 is connected to the storage chamber 9, which is generally inverted trapezoidal in shape, with the upper end larger than the lower end. Multiple vertically aligned rotating cutter shafts 10 are positioned at the center of the storage chamber 9. A rotating cutter holder 11 is fixed to the upper end of each rotating cutter shaft 10, and multiple crushing blades 12 are mounted on the rotating cutter holder 11. Each crushing blade 12 is bent at a 90-degree angle; the vertical part is fixed to the rotating cutter shaft 10, and the part perpendicular to the vertical part is parallel to the bottom of the bin, with a cutting edge on one side of this part. Multiple crushing blades 12 are evenly arranged on each rotating cutter shaft 10, and adjacent crushing blades 12 face opposite directions, one blade pointing upwards and the other downwards, but the direction of the cutting edges is consistent. When the material initially crushed by the feeding bin 3 enters the storage chamber 9, all the rotating cutter shafts 10 rotate rapidly in the direction of the cutting edges, performing secondary crushing of the material.

[0036] A removable filter screen 13 is installed at the lower end of the storage chamber 9 to prevent larger material particles from falling out. The crushed material passes through the filter screen 13 and falls into the bottom discharge port 14. Material that is not completely crushed is blocked by the filter screen 13. Since the filter screen 13 is located close to the rotating blade shaft 10 and the rotating position of the crushing blade 12, directly below the rotating blade shaft 10 and as close as possible to the crushing blade 12, the material isolated by the filter screen 13 is blown up by the airflow brought by the rotating blades and finally crushed by the crushing blade 12.

[0037] Installation steps: First, install the main roller 4 into the feeding bin 3 via connecting shafts at both ends, ensuring it can rotate freely. Then, fix the stepped blade holder 5 into the blade holder groove 6 of the main roller 4 with screws, making the surface of the stepped blade holder 5 flush with the surface of the main roller 4. Next, install the cutting blade 7 on the stepped blade holder 5, ensuring consistent blade spacing. Install cutting grooves 8 on the inner walls of both sides of the feeding bin 3, ensuring they accurately align with the cutting blade 7. Install the rotating blade shaft 10 at the centered position of the storage chamber 9, and fix the rotating blade holder 11 and the crushing blade 12. Install the removable filter screen 13 at the lower end of the storage chamber 9, and finally connect the discharge port 14. After installation, perform debugging to check whether the rotation of each component is smooth and whether there is any interference.

[0038] Working Principle: When plant materials need to be crushed, the material is fed into the feeding bin 3 through the feeding port 2. The equipment is started, and the main roller 4 rotates in the direction of the bend of the cutting blade 7. The cutting blade 7 rotates accordingly, using its curved shape to pull the material to one side of the feeding bin 3. As it passes through the cutting groove 8, the action between the cutting blade 7 and the cutting groove 8 cuts the material into segments. Multiple stepped blade holders 5 cut the material into many small segments. In areas without stepped blade holders 5, the material becomes relatively large segments. These segmented materials enter the lower end of the feeding bin 3 through the rotation of the main roller 4 and fall into the storage chamber 9. Inside the storage chamber 9, the rotating blade shaft 10 rotates rapidly in the direction of the blade edge, performing secondary crushing on the incoming material. The crushed material falls, and the crushed material passes through the filter screen 13 and is discharged from the outlet 14; the incompletely crushed material is blocked by the filter screen 13. Because it is close to the rotating blade shaft 10 and the crushing blade 12, it is blown up by the air generated by the rotation and crushed again by the crushing blade 12.
