Abstract
Description
Technical Field
[0001] This utility model relates to the field of straw feed production technology, specifically to a device for solid-state fermentation of crop straw to produce feed. Background Technology
[0002] In the current process of straw recycling, the most common methods are returning straw to the field and using it as feed. The use of straw as cattle feed is already being implemented in many places. The general storage method involves chopping fresh straw and placing it in an airless storage pit. This allows anaerobic lactic acid bacteria to grow rapidly on the corn stalks, producing a large amount of lactic acid bacteria. When this reaches a certain level, it can significantly inhibit mold growth, allowing the straw to be stored for a long time. However, the conventional straw feed production process is relatively cumbersome, consuming a lot of manpower, resources, and time. Therefore, a convenient straw feed production equipment is needed.
[0003] As disclosed in the patent announcement CN211671467U, a sorghum straw feed production and processing equipment includes a device body, a water tank, support legs, and a second servo motor. The device body has a feed inlet at the center of its top. A control panel is installed at one end of the device body, and a microcontroller is embedded within the control panel. Third servo motors are installed at both ends of the device body, and a wheel is mounted on each of the third servo motors via a coupling. A central shaft is mounted on the wheel, and a movable plate is hinged to the central shaft. One end of the movable plate is connected to a first connecting rod. A connecting plate is installed inside the device body, and a free-pressing plate exists between the connecting plates. This invention utilizes a fan to drive airflow, which carries dust from the first connecting pipe into a protective cover, and then from the second connecting pipe into the water tank. The dust is absorbed by the water in the tank, thus achieving dust removal and ensuring the health of the operators. However, the structure of this utility model is relatively complex and lacks stirring and sealing measures, which makes it difficult to ensure the uniformity of mixing between the raw materials and fermentation bacteria and the airtightness of the fermentation process, and easily leads to the growth of mold. To address this, we have proposed a solid-state fermentation equipment for crop straw to produce feed, which solves the problems of uniform mixing and airtightness of the production process of this utility model, and improves the practical effect and production quality of this utility model.

[0020] Please see Figures 1-4 As shown, this utility model provides a technical solution:
[0021] A solid-state fermentation device for producing feed from crop straw includes a working box shell 100, inside which a fermentation cylinder 101 is installed. A stirring mechanism is installed inside the fermentation cylinder 101, and a heating mechanism is installed on the outside of the fermentation cylinder 101. The top of the working box shell 100 has a straw feed inlet 102 and a fermentation bacteria inlet 103, and a water inlet pipe 104 is installed on one side of the working box shell 100. The stirring mechanism includes a drive motor 200, which is fixedly installed on the top of the working box shell 100. A stirring rod 201 is poweredly connected to the output end of the drive motor 200. A stirring blade 202 is fixedly installed on the outside of the stirring rod 201, and a spiral rod 203 is fixedly connected to the bottom end of the stirring rod 201.
[0022] In this embodiment, preferably, the fermentation cylinder 101 is provided with a discharge port 105 at the bottom end, the spiral rod 203 is located inside the discharge port 105, and the discharge port 105 is equipped with a discharge valve 106.
[0023] In this embodiment, preferably, support arms 204 are fixedly installed on both sides of the stirring rod 201, a wall-sweeping plate 205 is fixedly installed on one end of the support arm 204, and a brush 206 is provided on one side of the wall-sweeping plate 205, the brush 206 being in contact with the inner wall of the fermentation cylinder 101.
[0024] In this embodiment, preferably, the water inlet pipe 104 is equipped with a water stop valve 107, the straw crushing inlet 102 is provided with a retaining strip 300, the retaining strip 300 is wrapped with a rubber layer 301, the straw crushing inlet 102 is fitted with a sealing cap 302, the sealing cap 302 has a sealing groove 303, the sealing groove 303 and the retaining strip 303 are interlocked, and the fermentation biological bacteria injection port 103 is equipped with a silicone rubber stopper cap 304.
[0025] In this embodiment, preferably, an electric heating plate 108 is fixedly installed on the outer wall of the fermentation cylinder 101, and a temperature sensor 109 is fixedly installed at the top of the fermentation cylinder 101.
[0026] In this embodiment, preferably, the outer shell 100 of the work box is equipped with a control device 110, which is electrically connected to the drive motor 200, the electric heating plate 108 and the temperature sensor 109.
[0027] In this embodiment, a solid-state fermentation equipment for producing feed from crop straw involves the following steps: First, chopped straw is fed into the fermentation cylinder 101 through the straw feed inlet 102 located at the top of the outer shell 100. Then, water is added to the external water source through the water inlet pipe 104, filling the cylinder with water to approximately half the weight of the straw. The drive motor 200 is then started to stir the stirring rod 201 and stirring blade 202. After the mixture is evenly stirred, fermentation-aiding bacteria are added into the fermentation cylinder 101 through the fermentation bacteria inlet 103, and the mixture is stirred evenly again. In areas with low temperatures, the electric heating plate 108 can be activated to provide auxiliary heating to the fermentation cylinder 101, based on the suitable survival temperature of the fermentation bacteria, in order to increase the fermentation speed and ensure the production speed of the straw feed. During the fermentation process of straw feed, the sealing groove 303 inside the sealing cover 302 is fitted onto the straw feed inlet 102, allowing the locking strip 300 to embed inside the sealing groove 303. Since the outer side of the locking strip 300 is wrapped with a rubber layer 301, the rubber has excellent sealing properties, effectively sealing the gap between the locking strip 300 and the sealing groove 303, preventing air from entering the fermentation cylinder 101. The silicone rubber stopper 304 installed at the fermentation microbial inlet 103 achieves a sealing effect, thus ensuring the fermentation effect of the straw raw materials inside the fermentation cylinder 101 and preventing excessive air contact that could lead to mold growth. The wall-sweeping plate 205 and brush 206 in the stirring mechanism prevent feed from adhering to the inner wall of the fermentation cylinder 101, thus avoiding waste. The screw rod 203, which is fixedly connected to the bottom of the stirring rod 201, opens the discharge port 105 when the straw feed is fermented and discharged. The continuous rotation of the screw rod 203 can increase the discharge speed and prevent the discharge port 105 from being blocked, thereby improving the production efficiency of the equipment.
