DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0024] With reference to Figures 1-4 The composting device mainly comprises a tank body 1 and a cover body 2 to form a main frame. The tank body 1 is used for accommodating agricultural organic waste and is a main place for composting fermentation. The cover body 2 can reduce heat loss and odor emission, and provide a mounting base for auxiliary devices such as a spray device. For example, a hidden groove 5 is arranged to accommodate a spray plate 6, so that the device maintains simplicity and sealing when the spray function is not used.

[0025] The stirring shaft 9 rotates under the driving of the drive motor 3, and a plurality of stirring rods 10 mounted on the stirring shaft 9 can stir the organic waste in the tank body 1. The stirring operation is very important, which can uniformly mix the organic waste and ensure that different types and different positions of the waste can fully contact air, moisture and microorganisms and other factors to promote composting fermentation. For example, in the initial stage of composting, the newly added organic waste is stirred with the partially fermented material, which can accelerate the colonization and reproduction of microorganisms on the new material; during the fermentation process, stirring can prevent the material from caking and maintain good air permeability, which is beneficial to the continuous and efficient decomposition of organic matter by aerobic microorganisms.

[0026] The support plate 18 provides stable support for the function box 4. The material of the support plate 18 can be selected from high-strength steel or strong engineering plastic, so that the function box 4 will not shake or displace due to vibration or other external factors during the operation of the device. The connection between the support plate 18 and the tank body 1 can be welding (for metal tank body 1) or bolt fastening (for various materials), so as to ensure the firmness and stability of the connection.

[0027] The vertical meshing design of the driving gear 16 and the transmission gear 17 ingeniously transmits the power of the stirring shaft 9 to the reciprocating screw 13. The meshing mode of the bevel gear can realize the transmission of the power, so that the stirring shaft 9 rotating in the horizontal direction can drive the reciprocating screw 13 rotating in the vertical direction (or other set direction). For example, when the stirring shaft 9 rotates at a certain speed, the driving gear 16 rotates, and through the meshing with the transmission gear 17, the reciprocating screw 13 rotates according to the set transmission ratio, providing a power basis for the subsequent movement of the piston plate 14 and liquid spraying and other functions.

[0028] The adapter frame 15 is designed in a U shape, which not only ensures the stable threaded connection with the reciprocating screw 13, but also effectively connects the piston plate 14 with the reciprocating screw 13. When the reciprocating screw 13 rotates, the adapter frame 15 moves up and down along the screw due to the threaded cooperation between the adapter frame 15 and the screw, thereby driving the piston plate 14 to seal and slide in the activity chamber 12. This connection mode is simple in structure and high in reliability, and can accurately convert the rotary motion of the screw into the linear motion of the piston plate 14, thereby realizing the absorption and discharge operation of the external microbial agent.

[0029] The liquid inlet pipe 8 is used to supplement the microbial agent into the functional box 4. The first and second valves are one-way valves, which ensure that the liquid can only flow into the functional box 4 in one direction.

[0030] A plurality of spray heads can be arranged on the spraying plate 6, which can be atomizing spray heads or scattering spray heads according to actual needs. The atomizing spray head can spray liquid in the form of tiny droplets, uniformly covering the organic waste in the tank body 1, which is beneficial to the full contact between the liquid and the material and improves the utilization efficiency of the microbial agent or other additives; the scattering spray head can form droplet distribution on a larger area, which is suitable for quickly wetting the surface of the material.

[0031] Working principle: The transverse movement of the cover body 2 can make it separate from the tank body 1, and the spraying plate 6 is exposed and the slot of the tank body 1 is opened, so that air can enter the tank body 1. Then the driving motor 3 is started, at this time the stirring shaft 9 starts to rotate, on the one hand it stirs the organic waste, on the other hand it drives the reciprocating screw 13 to rotate through the meshing of the driving gear 16 and the transmission gear 17. The rotation of the reciprocating screw 13 drives the adapter frame 15 to move the piston plate 14 up and down in the activity chamber 12. When the piston plate 14 moves downward, the microbial agent stored in the external storage device enters the functional box 4 through the liquid inlet pipe 8; when the piston plate 14 moves upward, the liquid is squeezed to enter the spraying plate 6 through the liquid outlet pipe 7, and then is sprayed from the spraying plate 6 to fall on the organic waste in the tank body 1. In this way, the automatic spraying of the microbial agent is realized while stirring, which improves the efficiency and quality of composting.

[0032] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
