The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model provides a straw composting and recycling device. Figure 1-4 As shown, the straw composting and recycling device includes: a mounting base 1, on which a composting box 2 for straw composting and recycling is arranged, and the composting box 2 is provided with an electric heating pipe 3 for heating; a box cover 4 arranged on the top of the composting box 2; an auger 5 rotatably installed in the composting box 2 for guiding the composted straw; a first motor 6 fixed to one side of the composting box 2, and the output shaft of the first motor 6 is fixedly connected to the shaft of the auger 5; a discharge pipe 7 fixed to the composting box 2, and the discharge pipe 7 is provided with a material valve 8; and a spraying mechanism arranged on the composting box 2 for spraying composting liquid.

[0022] It should be noted that, at present, the main method of straw composting is to spray the composting agent and then pile it up in a centralized manner. Although this method is easy to operate, relatively low in cost, and can quickly process a large amount of straw, a series of problems have gradually emerged. First, the composting process is difficult to control. In the centralized stacking method, the composting of straw mainly depends on the sprayed composting agent and external environmental conditions. However, due to the uneven density and humidity of the straw stacking, as well as changes in external environmental factors such as temperature and humidity, the composting process is often difficult to achieve an ideal uniform and stable state. This leads to unstable composting effects, some straws may be over-composted, while others may be under-composted. Secondly, the quality of the fertilizer varies. Due to the instability of the composting process, the quality of the final fertilizer also varies greatly. Some straws may lose a lot of nutrients due to over-composting, while others may contain high levels of undecomposed substances due to under-composting. This quality instability makes it difficult to predict the effect of fertilizer use, which is not conducive to the growth of crops and the increase of yield. In addition, although the centralized stacking method is easy to manage, due to the instability of the composting process, managers need to frequently check and adjust, which increases the difficulty and cost of management. Therefore, a straw composting and recycling device is needed to solve the above problems.
