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.

[0025] Example: Reference Figure 1-Figure 3 The stem crushing mechanism for a pepper threshing device shown in the figure comprises two crushing rollers 1 arranged one above the other, each of which is covered with two detachable roller shells 2. A drive motor 6 and a transmission structure for driving the two crushing rollers 1 are mounted on one end of one of the crushing rollers 1.

[0026] A mounting base 4 is fixed on the outside of the roller shell 2, and a crushing knife 3 is movably inserted on the mounting base 4. Fastening nuts 5 for limiting the crushing knife 3 are respectively provided at both ends of the mounting base 4. The fastening nuts 5 are fixed to the mounting base 4 by friction on the side close to the mounting base 4.

[0027] Based on the above structure, when a certain (or several) crushing knives 3 need to be replaced, the staff only needs to unscrew the two fastening nuts 5 corresponding to the crushing knives 3 to pull the crushing knives 3 out of the mounting seat 4, so that a single crushing knives 3 can be replaced. After that, it is only necessary to insert the new (or polished) crushing knives 3 into the mounting seat 4, and then tighten the fastening nuts 5 so that the fastening nuts 5 and the mounting seat 4 are frictionally fixed, and the crushing knives 3 can be fixed. This makes it convenient for the staff to replace a single crushing knife 3, thereby reducing maintenance costs.

[0028] Furthermore, a groove is formed in the mounting base 4, and mounting holes 42 communicating with the groove are formed at both ends of the mounting base 4;

[0029] A mounting shaft 31 is fixed to the lower end of the crushing knife 3. Both ends of the mounting shaft 31 rotate through the two mounting holes 42 and extend to the outside of the mounting seat 4. Both ends of the mounting shaft 31 are provided with a thread groove 311 that is threadedly matched with the fastening nut 5.

[0030] In addition, the length of the lower end of the crushing knife 3 is less than the distance between the two mounting holes 42, that is, the lower end of the crushing knife 3 can move relative to the two mounting holes 42, so that the two ends of the mounting shaft 31 can be inserted into the two mounting holes 42;

[0031] A rough wall 51 is formed on one side of the fastening nut 5 close to the mounting seat 4 and is interference fit with the side wall of the mounting seat 4 .

[0032] By inserting the two ends of the mounting shaft 31 into the two mounting holes 42 and extending the two ends of the mounting shaft 31 to the outside of the mounting seat 4, and then tightening the two fastening nuts 5 on the threaded groove 311, so that the rough walls 51 of the two fastening nuts 5 are interference fit with the side walls of the mounting seat 4, the mounting shaft 31 can be limited, and the installation of the crushing knife 3 can be completed. The operation is convenient and quick; when disassembly is required, only the reverse operation is required, which makes it convenient for the staff to install and disassemble the single crushing knife 3 and facilitates maintenance.

[0033] Furthermore, the groove of the mounting seat 4 is an arcuate groove 41 that is slidably fitted with the mounting shaft 31. A relief slant wall 43 is formed on both sides of the upper end of the groove 41. The upper ends of the relief slant walls 43 are inclined away from the middle of the arcuate groove 41, and the two relief slant walls 43 form an outwardly expanding opening.

[0034] By setting the give-way inclined wall 43, the lower end of the crushing knife 3 can swing along the installation axis 31 in the space between the two give-way inclined walls 43, so that the inclination angle of the crushing knife 3 can be adjusted, so that the crushing surface formed by the crushing knife 3 is different, which meets the crushing needs of various pepper branches, thereby making the branch crushing mechanism of the pepper defruiting device more flexible and applicable to a wider range of uses, greatly improving the practicality of the branch crushing mechanism of the pepper defruiting device.

[0035] Furthermore, the maximum deflection angle of the crushing knife 3 between the two give-way inclined walls 43 is 45°, which can meet the various crushing requirements of the pepper branches in the prior art, and the lower end of the crushing knife 3 extends to the opposite sides of the give-way inclined wall 43 and is fixed with a flexible cushion layer 32. The flexible cushion layer 32 is made of a flexible material (such as rubber) commonly used in the prior art and suitable for this embodiment. It can form an elastic cushion layer between the crushing knife 3 and the give-way inclined wall 43 to avoid hard collision between the crushing knife 3 and the give-way inclined wall 43 due to vibration during use, and can extend the service life of the crushing knife 3 while facilitating the separate replacement of the crushing knife 3.

[0036] Furthermore, a limited insertion hole 11 is provided on the crushing roller 1, and a positioning column 21 is fixed on the inner side of the roller shell 2 and is plugged into and matched with the limited insertion hole 11;

[0037] A horizontally arranged connecting ear 22 is fixed to the end of the roller shell 2. The two roller shells 2 are fixedly connected by bolts passing through the connecting ear 22. The two roller shells 2 are fixedly installed by combining the connecting ear 22 with the bolts, which can improve the integrity of the two roller shells 2. At the same time, it can avoid opening a large number of side holes on the crushing roller 1, thereby ensuring the radial strength of the crushing roller 1.

[0038] When the tool 3 is replaced, the two ends of the tool 3 are tightened to the two ends of the tool 3. The tool 3 is fixed to the workbench 31 and the tool 3 is fixed to the workbench 31 so that the tool 3 can be fixed to the workbench 31 by screwing the two ends of the tool 3.

[0039] At the same time, before tightening the two fastening nuts 5, the staff can also adjust the inclination angle of the crushing knife 3 by moving the crushing knife 3 so that the crushing knife 3 swings along the mounting axis 31 in the space between the two yielding inclined walls 43, so that the crushing knife 3 can form different crushing surfaces to meet the crushing needs of various pepper branches and have a wider range of applications.
