Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a destemming device for easy blade replacement, including a support base 1, a base plate 2 installed at the top center of the support base 1, a placement groove 3 installed at the top center of the base plate 2, fixing brackets 4 installed at both ends of the top of the support base 1, a telescopic rod 5 vertically penetrating the top of the support base 1, an installation plate 6 installed at the bottom of the telescopic rod 5, a destemming component 7 installed at the bottom center of the installation plate 6, and limiting components 8 installed around the destemming component 7 at the bottom of the installation plate 6.

[0024] The destemming assembly 7 includes a frame 701 mounted at the center of the bottom of the mounting plate 6. A motor 702 is mounted on the inner side of the frame 701. The output shaft of the motor 702 is connected to a connecting sleeve 703. A connecting post 704 is mounted on the inner side of the connecting sleeve 703. Limiting rods 705 are mounted on both sides of the connecting post 704. A first spring 706 is mounted on the inner side of both ends of the connecting post 704. A limiting post 707 is mounted on one end of the first spring 706. A connecting plate 708 is mounted on the bottom of the connecting post 704. A cutting blade 709 is mounted on the bottom of the connecting plate 708 by bolts and nuts.

[0025] The limiting component 8 includes a first connecting rod 801 installed around the bottom of the mounting plate 6, a second spring 802 installed at the bottom of the first connecting rod 801, a second connecting rod 803 installed inside the second spring 802, a third connecting rod 804 installed at the bottom of the second connecting rod 803, and a pressing ring 805 installed at the bottom of the third connecting rod 804.

[0026] In this embodiment, as Figure 1 As shown, the telescopic rod 5 and the mounting plate 6 form a telescopic structure.

[0027] In this embodiment, as Figure 1 As shown, limit blocks are installed at both ends of the mounting plate 6, and limit grooves with the same external dimensions and structure as the limit blocks are opened at both ends of the inner side of the fixing frame 4.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the motor 702, connecting sleeve 703, connecting column 704, connecting disc 708 and cutting blade 709 constitute a rotating structure.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, the inner sides of the connecting sleeve 703 are provided with first grooves that are consistent with the external dimensions of the limiting rod 705, and the top of the connecting plate 708 and the cutting blade 709 are provided with mounting holes.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the limiting post 707 and the first spring 706 form an elastic structure, and the outer ends of the connecting sleeve 703 are provided with slots that are consistent with the external dimensions of the limiting post 707.

[0031] In this embodiment, as Figure 1 and Figure 4 As shown, the second spring 802 and the third connecting rod 804 form an elastic structure, and the bottom of the first connecting rod 801 is provided with a second groove that matches the external dimensions of the second connecting rod 803.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this easy-to-change-blade de-stemming device operates as follows:

[0033] First, place the material on top of the placement slot 3. Then, turn on the motor 702. The output shaft of the motor 702 will drive the connecting sleeve 703, connecting column 704, connecting plate 708, and cutting blade 709 to rotate. Then, extend the telescopic rod 5. At this time, the mounting plate 6 will move vertically and the limiting block will slide inside the limiting groove, thereby increasing the stability and limiting of the mounting plate 6 during movement. During the vertical movement of the mounting plate 6, the pressing ring 805 will first adhere to the material. Then, continue to extend the telescopic rod 5. The pressing ring 805 will press and limit the material. At the same time, the second spring 802 will undergo elastic deformation, causing the second connecting rod 803 to slide inside the second groove of the first connecting rod 801. At this time, the cutting blade 709 will slowly contact the material, thereby removing the stem from the material. When the stem removal is completed, extend the telescopic rod 5. When the spring 802 extends and retracts, it undergoes elastic deformation, causing the height of the pressing ring 805 to be lower than the height of the cutting blade 709, thus preventing accidental contact by the operator. When the cutting blade 709 needs to be replaced, the limiting posts 707 at both ends are pressed. At this time, the first spring 706 undergoes elastic deformation, causing the limiting posts 707 to disengage from the slot. Then, the connecting post 704, connecting plate 708, and cutting blade 709 can be disassembled. During the disassembly process, the limiting rod 705 will slowly disengage from the first groove inside the connecting sleeve 703, thus releasing the limiting position. At this time, the connecting post 704, connecting plate 708, and cutting blade 709 can be disassembled. Then, the bolts and nuts can be removed to disengage them from the mounting holes of the connecting plate 708 and cutting blade 709, thereby disassembling the cutting blade 709 and allowing for its replacement.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
