Description

Technical Field

[0001] The utility model relates to the technical field of sawdust recovery and processing, in particular to a sawdust fermentation bin. Background Art

[0002] Sawdust is a good renewable resource and can be used for many purposes. It can be used as crude protein feed for lower animals, and can also be added with an appropriate amount of nitrogen source, such as nitrogen fertilizer, poultry feces and urine, etc., and then added with a prepared fermentation agent and rice bran mixture, fully mixed and fermented as a high-quality nutrient soil ingredient for seedlings and flowers. The Chinese utility model patent with authorization announcement number CN206949505U discloses a sawdust fermentation box, including a fermentation box body and a mobile frame. The left side of the top of the fermentation box body is hinged with a sealing cover through a rotating shaft, and a thickening plate is fixed on the side end face of the sealing cover. A temperature sensor is installed on the side end face of the thickening plate. A control panel is installed in the inner cavity of the sealing cover, and the control panel is connected to the temperature sensor through a wire. An alarm is nested in the top corner of the sealing cover, and the alarm is connected to the control panel through a wire. Sliding grooves are opened in the horizontal direction on the top of the side walls on both sides of the inner cavity of the fermentation box body, and rollers are rotatably connected to the left and right sides of the mobile frame. The mobile frame is slidably connected to the inner cavity of the sliding groove through the roller, and a pressure roller is rotatably connected to the bottom end of the mobile frame in the horizontal direction. However, the fermentation process requires regular turning of the materials to ensure sufficient and uniform fermentation. The prior art lacks a turning device, and turning and mixing of the materials is often done manually by staff, who need to use hand-held tools to turn and mix the sawdust, which is time-consuming and laborious, and the turning efficiency is low. In addition, the existing sawdust fermentation equipment is unable to discharge the residual liquid generated in the spraying in time when spraying the sawdust, which will cause the sawdust at the bottom to rot and become unusable, thereby causing a waste of resources and increasing production costs.
