[0002] The rice planting area of China accounts for about one third of the total grain crop area, and rice is planted all over the country. Rice straw is a byproduct of rice, and its annual output is extremely huge. In the past, the utilization of rice straw has been at a general level, and the development and comprehensive utilization of rice straw have not been paid enough attention. In some places, rice straw is used as organic fertilizer instead of chemical fertilizer, and in some places, rice straw is directly burned, which is a waste of rice resources and a pollution of the atmospheric environment. With the development of science and technology and the promulgation of laws and regulations prohibiting open burning of straw, the comprehensive utilization of rice straw has gradually been paid attention to and promoted, and the main application directions are fertilizer, livestock, edible fungi, energy, and processing industry.

[0045] Through the above technical scheme, after the straw bales are placed on the placing table 12, the two chains 111 can drive the straw bales to move towards the dispersion assembly 13, the clamping teeth on the two chains 111 can be embedded into the bottom of the straw bales, so as to clamp the straw bales and prevent the straw bales from stopping moving on the placing table 12; the plurality of dispersion knives 133 can scatter the straw bales in the process of rapid rotation, and the plurality of dispersion knives 133 are staggered distributed, which increases the contact area of the dispersion knives 133 and the straw bales, prevents small straw blocks from passing through the gap of the dispersion knives 133, and ensures that all the straws passing through the horizontal shaft 131 are in a scattered state; the poking assembly 15 can poke the straws in the shell 14 to the first conveying belt device 2, so as to prevent the straws from accumulating in the shell 14.

[0046] In this embodiment, the silo body 31 is funnel-shaped, and each of the four outer corners of the upper end of the silo body 31 is fixedly connected to a column 32; both ends of the two rotating baffles 34 are rotatably connected to a connector 35, and the ends of the multiple connectors 35 away from the rotating baffles 34 are respectively fixedly connected to the outer sides of the bottom ends of the silo body 31; the sum of the widths of the two rotating baffles 34 is greater than the width of the discharge port at the bottom of the silo body 31.

[0048] By adopting the above technical solution, the bin 31 serves as a temporary storage for straw. When the two rotating baffles 34 are in contact with each other and block the discharge port at the bottom of the bin 31, the straw will not fall onto the second conveyor belt device 4. When the two rotating baffles 34 move away from each other, the straw will fall through the gap between the two rotating baffles 34. The amount of straw falling is related to the distance between the two rotating baffles 34. By adjusting the distance between the two rotating baffles 34, the amount of straw entering the crushing device 5 can be changed.

[0049] In this embodiment, one end of each of the two rotating shafts 52 extends to the outside of the crushing chamber 51 and is coaxially fixedly connected to a gear 54, and the two gears 54 mesh with each other; one end of one rotating shaft 52 away from the gear 54 is fixedly connected to the output shaft of a motor 55, and the bottom of the motor 55 is fixedly connected to the top of the bracket 57.

[0050] The crushing chamber 51 is located inside the support 57, and the outside of the support 57 is fixedly connected to the support 57 by multiple angle irons 56; the bottom of the crushing chamber 51 is integrally provided with a discharge chamber 58.

[0051] By adopting the above technical solution, after the straw falls into the crushing chamber 51 through the second conveyor belt device 4, multiple crushing blades 53 work together to crush the straw. The multiple crushing blades 53 are spirally distributed on the rotating shaft 52, and the crushing blades 53 on the two rotating shafts 52 are staggered, which can increase the efficiency and effect of straw crushing. The auxiliary block 59 inside the crushing chamber 51 can block the straw from passing through, preventing uncrushed straw from falling into the discharge chamber 58. At the same time, the auxiliary block 59 is provided with a through groove for the crushing blades 53 to pass through, which will not affect the normal rotation of the crushing blades 53.

[0052] The working principle of this utility model is as follows: After the bundled straw is placed on the platform 12, the two chains 111 can drive the straw to move towards the dispersing component 13. The teeth on the two chains 111 can be inserted into the bottom of the straw, thereby locking the straw and preventing it from stopping on the platform 12. The multiple dispersing blades 133 can break up the straw during rapid rotation. The multiple dispersing blades 133 are staggered, which increases the contact area between the dispersing blades 133 and the straw, preventing small clumps of straw from passing through the gaps of the dispersing blades 133, and ensuring that all the straw passing through the horizontal axis 131 is in a dispersed state. The agitating component 15 can move the straw in the outer shell 14 onto the first conveyor belt device 2, preventing the straw from accumulating in the outer shell 14.

[0053] The bin 31 serves as a temporary storage for straw. When the two rotating baffles 34 are close together and block the discharge port at the bottom of the bin 31, the straw will not fall onto the second conveyor belt device 4. When the two rotating baffles 34 move away from each other, the straw will fall through the gap between the two rotating baffles 34. The amount of straw falling is related to the distance between the two rotating baffles 34. By adjusting the distance between the two rotating baffles 34, the amount of straw entering the crushing device 5 can be changed.

[0054] After the straw falls into the crushing chamber 51 via the second conveyor belt device 4, multiple crushing blades 53 work together to crush the straw. The multiple crushing blades 53 are spirally distributed on the rotating shaft 52, and the crushing blades 53 on the two rotating shafts 52 are staggered, which can increase the efficiency and effect of straw crushing. The auxiliary block 59 inside the crushing chamber 51 can block the straw from passing through, preventing uncrushed straw from falling into the discharge chamber 58. At the same time, the auxiliary block 59 is provided with a through groove for the crushing blades 53 to pass through, so as not to affect the normal rotation of the crushing blades 53.

[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
