Description

Technical Field

[0001] This utility model relates to the technical field of agricultural solid waste treatment equipment, specifically to a high-efficiency fermentation device for agricultural solid waste. Background Technology

[0002] Agricultural solid waste generally includes crop straw, etc. To achieve the goal of energy conservation and environmental protection, it is usually fermented. After fermentation, it becomes farmyard manure, which is returned to the soil to benefit crop growth.

[0003] CN 222099829 U discloses a novel high-efficiency fermentation device for agricultural solid waste, which includes an outer shell with four fermentation cylinders arranged in a ring inside the shell. A storage unit is connected to the top of each of the four fermentation cylinders. This device aims to achieve simultaneous fermentation of multiple wastes by storing different fermentation wastes in different fermentation cylinders through the cooperation between the outer shell and fixed columns, the four fermentation cylinders, and the discharge frame. This reduces the need for purchasing fermentation equipment, lowers production costs, and increases the efficiency of agricultural production. However, the following problems still exist: when the volume of the storage frame is large, it holds a large amount of material, making it heavy and difficult to lift out of the outer shell, thus hindering filling and emptying. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency fermentation device for agricultural solid waste that has a reasonable structure and reliable operation, which solves the above problems, facilitates filling and emptying of materials by workers, reduces labor intensity, and saves time and effort.

[0005] The technical solution of this utility model is:

[0006] A high-efficiency fermentation device for agricultural solid waste includes a fermentation tank buried underground with an open top, and multiple fermentation cylinders disposed within the fermentation tank.

[0018] The present invention will be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-3 As shown, the high-efficiency fermentation device for agricultural solid waste includes a fermentation tank 17 buried underground with an open top, and multiple fermentation cylinders 15 disposed in the fermentation tank 17.

[0020] In this embodiment, a guide post 9 is fixed at the center of the fermentation tank 17, with its upper end extending above the ground at a set height. The outer wall of the guide post 9 has longitudinal guide grooves 12 corresponding to the fermentation cylinders 15. Each fermentation cylinder 15 has a guide block that mates with the longitudinal guide grooves 12 on its side near the guide post 9. The side of the fermentation cylinder 15 away from the guide post 9 is attached to the inner wall of the fermentation tank 17. The top of the fermentation cylinder 15 is closed and a lifting rod 13 is fixed in place. In this embodiment, the fermentation cylinders 15 are evenly arranged around the guide post 9, with the side walls of adjacent fermentation cylinders 15 touching. A feed inlet 19 is provided on the upper part of the side wall of each fermentation cylinder 15, and the inner bottom surface of each fermentation cylinder 15 is inclined, with a discharge valve 18 at the lower end of the inclined surface. Heating jackets 16 are provided on the side walls and bottom of the fermentation tank 17 to accelerate the fermentation process.

[0021] A horizontal support 1 is fixed to the upper end of the guide column 9, and multiple columns 8 are fixed between the edge of the horizontal support 1 and the ground. A turntable 7 is fixed to the middle of the upper surface of the horizontal support 1, and a winch 6 is fixed above the turntable 7. A support arm 4 is fixed to the side of the rotating part of the turntable 7, and a guide wheel assembly 5 is fixed to the upper surface of the support arm 4. The end of the lifting rope 11 of the winch 6 extends towards the fermentation tank 15 after passing over the guide wheel of the guide wheel assembly 5. The support arm 4 is provided with a through hole 20 corresponding to the lifting rope 11, the horizontal support 1 is provided with a clearance channel 10 corresponding to the lifting rope 11, and the lifting rod 13 is provided with a fixing hole 14 corresponding to the lifting rope 11. In this embodiment, the upper surface of the horizontal support 1 is provided with a track 2 arranged concentrically with the turntable 7, the track 2 is provided with a roller 3, and the axle of the roller 3 is connected and fixed to the end of the support arm 4. The clearance channel 10 is arranged concentrically with the turntable 7.

[0022] Working principle:

[0023] 1. In use, the end of the lifting rope 11 of the winch 6 passes over the guide wheel of the guide wheel assembly 5, and then connects and fixes to the lifting rod 13 of one of the fermentation cylinders 15 through the through hole 20 and the clearance channel 10. Start the winch 6 to lift the fermentation cylinder 15 to a certain height so that the feed inlet 19 of the fermentation cylinder 15 is exposed to the ground, making it convenient for workers to fill the fermentation material into the fermentation cylinder 15. After filling is completed, the winch 6 rotates in the reverse direction to lower the fermentation cylinder 15 back to its original position.

[0024] 2. After filling one fermentation tank 15, disconnect the lifting rope 11 from the previous fermentation tank 15. The turntable 7 drives the support arm 4 and guide wheel assembly 5 to rotate at a certain angle, so that the lower end of the lifting rope 11 is transferred to the top of another fermentation tank 15 and connected and fixed to the lifting rod 13 of this fermentation tank 15. Repeat the above operation to complete the filling of this fermentation tank 15. In this way, all fermentation tanks 15 can be filled, and different types of materials can be filled into different fermentation tanks 15.

[0025] 3. A heating medium is injected into the heating jacket 16 of the fermentation tank 17 to increase the fermentation speed.

[0026] 4. After fermentation is complete, use the winch 6 to lift the fermentation cylinder 15 out of the fermentation tank 17 to a certain height, move the receiving device below the fermentation cylinder 15, open the discharge valve 18, and discharge the fermented material in the fermentation cylinder 15 into the receiving device, saving time and effort.

[0027] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
