It belongs to the technical field of garbage treatment equipment, and particularly relates to a high-efficiency kitchen waste fermentation fertilizer device with drum stirring that preliminarily crushes kitchen waste through a crushing component and secondarily crushes kitchen waste while evenly mixing it with bacterial liquid through a fermentation component. Background Technique

[0002] The fermentation treatment of household kitchen waste into organic fertilizer for flower and grass cultivation is a powerful means to achieve resource recycling and turn waste into treasure. At present, the fermentation treatment methods of kitchen waste are mainly divided into two types. One is to cut kitchen waste into small particles manually and then lay it layer by layer with fermentation strains. However, this method has the problem of uneven stirring, and the treatment process is time-consuming, with high labor costs and low efficiency. Another method is to stir and mix kitchen waste through a fermentation fertilizer machine. However, most of the existing fermentation fertilizer machines on the market use a stirring shaft in the middle, and there are some problems in the operation process. First, the crushing fineness of kitchen waste is insufficient and the crushing is uneven, resulting in different particle sizes, and then the degree of decomposition in different parts is inconsistent. Second, during the stirring process, kitchen waste is easy to adhere to the cylinder wall, and the kitchen waste particles at the bottom layer will accumulate and cannot fully contact with the strains, resulting in uneven stirring of the strains and kitchen waste. The above problems directly affect the fermentation efficiency, prolong the fermentation time, and cannot guarantee the effect of fermenting into fertilizer.

[0003] Publication No. CN220432658U discloses a combined kitchen waste fermentation and fertilizer production machine, which includes a box body. Inside the box body, a crushing bin, a fermentation bin and a fertilizer storage bin are sequentially arranged from top to bottom; a crushing assembly is arranged in the crushing bin, and the crushing assembly is used for crushing the input kitchen waste; a stirring assembly is arranged in the fermentation bin. This combined kitchen waste fermentation and fertilizer production machine puts kitchen waste and fermentation bacteria agent into the crushing bin, crushes them through the crushing assembly, then enters the fermentation bin through a sieve for fermentation. After fermenting in the fermentation bin for a period of time, the fermented fertilizer is put into the fertilizer storage bin through controlling a solenoid valve for use; Publication No. CN113354451A discloses a kitchen waste treatment device, which includes a frame, a crushing and squeezing device, an oil-water separation device, a heating and fermentation device and an air purification device. The crushing and squeezing device is arranged on the frame. The oil-water separation device is arranged on the frame, and the oil-water separation device is located below the crushing and squeezing device, and the oil-water separation device is communicated with the crushing and squeezing device. The heating and fermentation device is arranged on the frame, the heating and fermentation device is located below the crushing and squeezing device and on one side of the oil-water separation device, and one end of the heating and fermentation device is communicated with the crushing and squeezing device. The air purification device is arranged on the frame, the air purification device is located on one side of the heating and fermentation device, and the air purification device is communicated with the other end of the heating and fermentation device. During the crushing process of the above combined kitchen waste fermentation and fertilizer production machine, the crushing fineness is insufficient and the crushing is uneven, resulting in different particle sizes, and further causing inconsistent degree of decomposition in different parts. At the same time, during the stirring process, the kitchen waste is easy to adhere to the cylinder wall, and the kitchen waste particles at the bottommost layer will accumulate, unable to fully contact with the bacteria, and the bacteria and the kitchen waste are not evenly stirred. The above problems directly affect the fermentation efficiency, prolong the fermentation time, and cannot guarantee the effect of fermenting into fertilizer. Summary of the Utility Model

[0107] There are multiple groups of the bacterial liquid spraying holes 17. Each group of the bacterial liquid spraying holes 17 is arranged at equal circumferential distances along the bacterial liquid spraying pipe 16. There are multiple bacterial liquid spraying holes 17 in each group, and the design that the multiple bacterial liquid spraying holes 17 in each group are arranged at equal axial distances along the bacterial liquid spraying pipe 16 can spray the inside of the mixing drum 10 comprehensively and make the bacterial liquid and the kitchen waste fully mixed;

[0108] The side of the crushing rod 11 is evenly distributed with a design of secondary cutting, which can crush kitchen waste for the second time, make its particles more uniform, improve the consistency of the degree of decomposition, and thus improve the fermentation efficiency;

[0109] It achieves the purpose of initially crushing kitchen waste through the crushing component, secondarily crushing kitchen waste through the fermentation component and evenly mixing it with the bacterial liquid at the same time.

[0110] It should be noted that unless otherwise clearly specified and limited, the terms "placed", "connected", and "joined" should be understood in a broad sense. For example, it can be a fixed connection method such as hemmed connection, rivet connection, pin connection, adhesive connection, and welding connection, or a detachable connection method such as threaded connection, snap connection, and hinge connection, or an integral connection, or it can be an electrical connection, or directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components.
