Technical Field
[0001] The utility model relates to the technical field related to straw crushing, in particular to a straw crushing and drying device. Background Art
[0002] Corn stalks are a dual-purpose crop used as food, cash crop and fodder, and are also an important production resource for industrial and agricultural production. Corn stalks are rich in nutrients and available chemical components, and can be used as a raw material for animal husbandry feed. During the reprocessing of corn stalks as biomass raw materials, they need to be crushed and dried. Existing straw processing usually involves cutting and crushing them first, and then using a hot air blower to dry them. However, the straw fragments produced by cutting may vary greatly in size, and the cut straw fragments are piled up together, which makes it impossible to dry the internal straw fragments, resulting in uneven drying that affects subsequent use.
[0003] Therefore, we propose a straw crushing and drying device to solve the above problems. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0024] Reference Figure 1-4 A straw crushing and drying device comprises a shell 1, and a leg is connected to the lower end surface of the shell 1 to ensure the overall stability of the device. A crushing chamber 2 and a drying chamber 3 are arranged in the inner cavity of the shell 1. A viewing port 101 that passes through the inside and outside is opened on the side wall of the front end of the shell 1, and the viewing port 101 corresponds to the connection position of the crushing chamber 2 and the drying chamber 3. A stirring rod 301 is rotatably connected to the side wall of the inner cavity of the drying chamber 3, and a group of arc-shaped blades 302 are connected to the side wall of the stirring rod 301. The external hot air drives the blades 302 to rotate to lift the internal straw residue, thereby ensuring that the straw residue is fully contacted with the hot air. A discharge port 8 is opened on the lower end surface of the drying chamber 3 to discharge the straw residue after crushing and drying for subsequent use. A group of sealing plates 801 are rotatably connected in the discharge port 8 to close the discharge port 8 to prevent leakage.
[0025] A cutting roller 4 and a crushing roller 5 are respectively arranged in the inner cavity of the crushing chamber 2. The cutting rollers 4 and the crushing rollers 5 on both sides rotate in opposite directions. A transmission wheel 401 is connected to the side wall of the rotating shaft of the cutting roller 4 and the crushing roller 5, and a transmission belt 402 is sleeved on the outer side of the transmission wheel 401 on the same side.
[0026] The drying chamber 3 is arranged at the lower side of the crushing chamber 2, and a horizontal screen plate 6 is arranged between the two. As the straw is screened, the larger debris is screened out for crushing again. A slot 601 that passes through the inside and outside is opened on the side wall of the shell 1. The screen plate 6 is inserted in the slot 601. The screen plate 6 is C-shaped as a whole. A scraper 602 is arranged on the inside of the screen plate 6. A pull-out rod 603 is connected to the side wall of the scraper 602. The pull-out rod 603 extends through the side wall to the outside. The pull-out rod 603 drives the scraper 602 to work and move the large-volume debris to the positions on both sides of the screen plate 6 to prevent it from clogging the screen plate 6, thereby facilitating the smooth progress of the screening process.
[0027] A heating chamber 7 is provided in the inner wall of the shell 1 on both sides of the drying chamber 3, and an electric heating plate 701 is installed on the inner wall of the heating chamber 7. A guide hole 702 penetrating on both sides is opened between the heating chamber 7 and the drying chamber 3, and an exhaust fan 703 is installed in the guide hole 702. The operation of the exhaust fan 703 drives external hot air to enter the drying chamber 3, thereby drying the straw residue. At the same time, the position of the guide hole 702 corresponds to the position of the blade 302, so that the hot air drives the blade 302 to rotate and lift the residue, thereby achieving a better drying effect and improving the drying efficiency.
[0028] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
[0029] In the description of the present invention, it is necessary to understand that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
