Description

Technical Field

[0001] This utility model belongs to the field of straw shredding technology, specifically relating to a straw shredder for rapid fermentation. Background Technology

[0002] Straw fermentation is a complex biochemical process, and fresh, mold-free straw should be selected. The moisture content of the straw is also crucial; generally, the suitable moisture content is 60%-70%. It is best to crush the straw to increase the contact area between the straw and the fermentation agent and air, which is conducive to the growth and fermentation of microorganisms.

[0003] Publication (Announcement) No.: CN220235482U. This utility model discloses a novel straw shredder, relating to the field of straw shredding technology. It includes a shell mechanism with a shredding mechanism fixedly connected inside, and a water spraying mechanism fixedly connected to one side of the shell mechanism. This utility model involves placing straw into the feed inlet upon startup, which then enters the shredding chamber under the conveyor belt. The rotation of a motor shaft drives the shredding blades to shred the straw within the shredding chamber. The two sets of staggered shredding blades improve the shredding effect. The cylindrical shape of the shredding chamber better matches the movement trajectory of the shredding blades, preventing straw from sliding directly off the inner wall of the chamber. Subsequently, the rotation of a second motor shaft causes the spiral blades to rotate, resulting in faster discharge speed and preventing clogging. This solves the problems of some straw sliding directly from the edge of the shredding chamber and the tendency for the discharge port to become clogged during discharge.

[0004] Analysis revealed that while the current solution uses two sets of shredders to shred the straw, even with a cylindrical internal design, some straw still gets trapped in the gaps between the inner wall and the blades, resulting in poor shredding. Furthermore, the intact structure makes cleaning difficult after a period of use, leading to the accumulation of straw fragments. Premature mold growth inside can affect later straw fermentation, making cleaning inconvenient. Therefore, the solution needs optimization and improvement to address these issues. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a straw shredder for rapid fermentation; it has a more efficient crushing capacity and is convenient for daily cleaning.

[0006] This utility model provides a straw shredder for rapid fermentation, comprising a first support, a second support, a curved pipe, and a cylinder. The curved pipe and the cylinder are interconnected. The first support is fixedly connected to the cylinder. A drive motor is fixedly installed on the second support. The cylinder contains a shredding component that facilitates cleaning. The shredding component includes a bearing located in the cylinder. The output end of the drive motor extends into the cylinder through the bearing and is fixedly installed with a transmission rod. Several shredding blades are evenly fixedly installed on the transmission rod. A cover plate is hinged to the cylinder. The cover plate and the inner wall of the cylinder have annular grooves corresponding to the shredding blades. One end of each shredding blade extends into the annular groove and is slidably connected to the inner wall of the annular groove. A discharge pipe is provided below the side of the cylinder away from the curved pipe.

[0007] Furthermore, a funnel is connected to the curved pipe.

[0008] Furthermore, both bracket one and bracket two have a base plate fixedly installed at their lower ends.

[0009] Furthermore, a locking mechanism is provided between the cover plate and the cylinder body.

[0010] Furthermore, a handle is fixedly installed on the cover plate.

[0011] Furthermore, the cover plate is evenly provided with a number of observation windows.

[0012] Furthermore, the height of bracket one is higher than the height of bracket two.

[0013] The beneficial effects of this utility model are:

[0014] This utility model, through structural improvements and optimizations, utilizes the height difference between support one and support two to enable the straw to actively flow downwards during the crushing process, resulting in more thorough crushing. The connection between the annular groove and the crushing blade ensures that the straw passes through the cylinder without gaps, further enhancing the crushing effect. The cover plate designed on the cylinder allows for convenient and regular opening for internal cleaning, ensuring a more thorough cleaning and preventing residual straw from fermenting and becoming moldy.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please refer to the accompanying diagrams for all instruction manuals:

[0025] A straw shredder for rapid fermentation includes a support frame 1, a support frame 2, a bent pipe 3, and a cylinder 4. The bent pipe 3 and the cylinder 4 are interconnected. The support frame 1 is fixedly connected to the cylinder 4. A drive motor 5 is fixedly installed on the support frame 2. The cylinder 4 is equipped with a shredding component that facilitates cleaning.

[0026] The easy-to-clean crushing component includes a bearing located in the cylinder body 4. The output end of the drive motor 5 extends into the cylinder body 4 through the bearing and is fixedly installed with a transmission rod 6. Several crushing blades 7 are evenly fixedly installed on the transmission rod 6. A cover plate 8 is hinged to the cylinder body 4. The cover plate 8 and the inner wall of the cylinder body 4 are provided with annular grooves 9 corresponding to the crushing blades 7. One end of the crushing blade 7 extends into the annular groove 9. The crushing blade 7 is slidably connected to the inner wall of the annular groove 9. A discharge pipe 10 is provided below the side of the cylinder body 4 away from the bend 3.

[0027] As can be seen from the above description, the drive motor 5 is controlled to work, causing the transmission rod 6 to rotate, which in turn drives the crushing blade 7 to rotate. When the crushing blade 7 rotates along the inner wall of the annular groove 9, the crushing effect of the straw can be guaranteed. The straw is put into the curved pipe 3, and it is crushed by the crushing blade 7 using the weight of the straw. As the straw moves, it is finally discharged through the discharge pipe 10.

[0028] As a technical optimization of this utility model, a funnel 11 is connected to the bend 3;

[0029] As can be seen from the above description, the funnel 11 has a large opening area, which makes it convenient for workers to pour straw into the curved pipe 3.

[0030] As a technical optimization of this utility model, the lower ends of both bracket 1 and bracket 2 are fixedly installed with base plate 12;

[0031] As can be seen from the above description, the base plate 12 can increase the contact area between the support 1 and the support 2 and the ground, thereby reducing the pressure.

[0032] As a technical optimization of this utility model, a locking buckle 13 is provided between the cover plate 8 and the cylinder body 4;

[0033] As can be seen from the above description, the latch 13 is used to connect and separate the cover plate 8 and the cylinder body 4, thereby improving the stability of the connection between the cover plate 8 and the cylinder body 4.

[0034] As a technical optimization of this utility model, a handle 14 is fixedly installed on the cover plate 8;

[0035] As can be seen from the above description, the handle makes it easier for workers to control the opening and closing of the cover plate 4.

[0036] As a technical optimization of this utility model, a plurality of observation windows 15 are evenly provided on the cover plate 4;

[0037] As can be seen from the above description, the observation window 15 allows workers to easily check the internal crushing process and, even if adjustments are made, to see if cleaning is required.

[0038] As a technical optimization of this utility model, the height of bracket 1 is higher than the height of bracket 2;

[0039] As can be seen from the above description, by utilizing the height difference design, the straw can be automatically moved to the discharge pipe 10 inside the cylinder 4, and the straw will not accumulate.

[0040] Working principle:

[0041] The drive motor 5 is controlled to work, causing the transmission rod 6 to rotate, which in turn drives the crushing blade 7 to rotate. When the crushing blade 7 rotates along the inner wall of the annular groove 9, it can ensure the crushing effect of the straw. The straw is put into the curved pipe 3, and it is crushed by the crushing blade 7 using its own weight. As the straw moves, it is finally discharged through the discharge pipe 10. When cleaning is required, the latch 13 is opened and the cover plate 8 is flipped open, so that the crushing blade 7 and the annular groove 9 can be cleaned directly, and the cleaning effect is better.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
