[0003] In existing technologies, crop straw is usually cut into sections by manual cutting. However, in actual use, if the amount of straw is large, a lot of manual labor is required to cut the straw, which is not only inefficient but also wastes a lot of manpower. Therefore, a cutting device for processing crop straw is proposed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please refer to the following: Figures 1-4 This utility model provides a technical solution: a cutting device for processing crop straw, including a feeding seat 1, a lead screw 2 rotatably connected inside the feeding seat 1, a motor 3 fixedly installed on the rear outer surface of the feeding seat 1, the output end of the motor 3 fixedly connected to the lead screw 2, a threaded block 4 threadedly connected to the outer surface of the lead screw 2, a connecting block 5 fixedly connected to the top outer surface of the threaded block 4, a conveying plate 6 fixedly connected to the top outer surface of the connecting block 5, a gantry frame 7 fixedly connected to the top outer surface of the conveying plate 6, a first cylinder 9 fixedly installed on the top outer surface of the gantry frame 7, and a first cylinder 9 fixedly connected to the output end of the first cylinder 9. The pressing plate 10 and the gantry frame 7 are fixedly connected to the opposite outer surfaces of the pressing plate 10 and the gantry frame 7. Specifically, the crop straw that needs to be cut is placed on the horizontal plate 20 and one end of it is attached to the placement plate 8. The first cylinder 9 works and drives the pressing plate 10 to move downward, so that the pressing plate 10 presses one end of the straw onto the placement plate 8. The motor 3 works and drives the lead screw 2 to rotate. The lead screw 2 drives the threaded block 4 to move. The threaded block 4 drives the connecting block 5 to move the conveying plate 6, thereby moving the gantry frame 7. The gantry frame 7 pushes one end of the straw to perform the cutting work.

[0023] In this embodiment, a U-shaped frame 11 is fixedly connected to the front end of the feeding seat 1. A second cylinder 12 is fixedly installed on the top of the U-shaped frame 11 facing downward. A connecting plate 13 is fixedly connected to the output end of the second cylinder 12. A cutting blade 14 is installed on the bottom outer surface of the connecting plate 13. Specifically, the second cylinder 12 drives the connecting plate 13 to move down and back up and down, so that the cutting blade 14 cuts one end of the straw.

[0024] In this embodiment, a conveyor belt 16 is provided on the lower front side of the feeding seat 1. Specifically, the straw chopped pieces fall onto the conveyor belt 16 for conveying.

[0025] In this embodiment, two uprights 18 arranged symmetrically on the top outer surface of the feeding seat 1 are fixedly connected. A longitudinal bar 19 is fixedly connected to the outer surface of the uprights 18. A horizontal plate 20 is fixedly connected between the two longitudinal bars 19. The height of the placement plate 8 is higher than the height of the horizontal plate 20. Specifically, the straw is supported by the horizontal plate 20. The height of the placement plate 8 is higher than the height of the horizontal plate 20 to avoid the horizontal plate 20 from blocking the placement plate 8.

[0026] In this embodiment, a receiving plate 17 is fixedly connected to the top outer surface of the feeding seat 1 below the cutting blade 14. Specifically, the straw is cut by contacting the cutting blade 14 with the receiving plate 17.

[0027] In this embodiment, baffles 21 are fixedly connected to the outer surfaces of the top left and right ends of the conveyor belt 16. Specifically, the baffles 21 limit the two sides of the conveyor belt 16 to prevent the cut straw from falling from the two sides of the conveyor belt 16.

[0028] In this embodiment, a groove is provided on the outer surface of the feeding seat 1, and the connecting block 5 is slidably connected to the inside of the groove. Specifically, when the lead screw 2 rotates, it drives the threaded block 4 to move, so that the connecting block 5 slides inside the groove, and the groove provides a channel for the movement of the connecting block 5.

[0029] In this embodiment, a guide plate 15 is fixedly connected to the bottom outer surface of the connecting plate 13. The guide plate 15 is located in front of the cutting blade 14. Specifically, when the second cylinder 12 drives the cutting blade 14 to move downward, the guide plate 15 moves downward. The guide plate 15 presses down one end of the cut straw, so that the straw can be separated from the receiving plate 17 and fall onto the conveyor belt 16.

[0030] Working principle: In use, the crop stalks to be cut are placed on the horizontal plate 20, with one end overlapping the placement plate 8. The first cylinder 9 drives the pressing plate 10 downward, pressing the straw end onto the placement plate 8. The motor 3 drives the lead screw 2 to rotate, which in turn moves the threaded block 4. The threaded block 4 moves the connecting block 5, causing the conveyor plate 6 to move, which in turn moves the gantry frame 7. The gantry frame 7 pushes one end of the straw. At the same time, the second cylinder 12 moves the connecting plate 13 downward and back and forth, causing the cutting blade 14 to cut one end of the straw. As the gantry frame 7 moves, the straw is cut completely. The straw segments fall onto the conveyor belt 16 for transport, thus improving the automation and efficiency of straw cutting.

[0031] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
