They should not be understood as limitations of the present invention.

[0029] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0030] like Figure 1-5As shown, this embodiment proposes a crop organic fertilizer fermentation device, which includes a fermentation barrel 1. The fermentation barrel 1 is a horizontal hollow barrel structure. Two legs are fixedly connected to the bottom of the fermentation barrel 1, and the fermentation barrel 1 also includes a feed port opened above the fermentation barrel 1. A detachable sealing cover 2 is provided on one side of the fermentation barrel 1, and a handle 14 is connected to the outside of the sealing cover 2. A motor 3 is provided on the other side of the fermentation barrel 1. Specifically, a bracket 18 is fixed on one side of the fermentation barrel 1, and a motor 3 is fixed above the bracket 18. The drive shaft of the motor 3 is connected to a rotating shaft 4, and the rotating shaft 4 is horizontally placed in the fermentation barrel 1. A rotatable stirring roller 5 is connected to the sealing cover 2, and a scraper 6 is fixedly connected to the other side of the stirring roller 5. The stirring roller 5 and the scraper 6 are slidingly sleeved on the rotating shaft 4 and rotate synchronously with the rotating shaft 4. A plurality of groups of stirring blades 7 are fixedly connected to the outer wall of the stirring roller 5.

[0031] During actual use, the organic waste is put into the fermentation barrel 1 from the feed port, the bottom of the fermentation barrel 1 is heated, and then the motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 further drives the stirring roller 5 and the stirring blade 7 to rotate, stirring the organic fertilizer inside the fermentation barrel 1 to help it further ferment; when the stirring and fermentation is completed, the fermented organic fertilizer inside the fermentation barrel 1 needs to be taken out, and the sealing cover 2 is pulled out through the handle 14. Since the sealing cover 2 is connected to the stirring roller 5 and the scraper 6, the stirring roller 5 slides outward along the rotating shaft 4 during the extraction process, and the fermented organic fertilizer inside the fermentation barrel 1 is pulled out through the sealing cover 2, and the stirring roller 5 and the stirring blade 7 leak out to the outside of the fermentation barrel 1, which is convenient for further cleaning of the organic fertilizer adhering to the stirring roller 5 and the stirring blade 7, so as to achieve the purpose of no waste and no residue, and keep the inside of the stirring barrel clean when not idle.

[0032] Compared with the prior art, this method can more conveniently discharge the fermented fertilizer, and at the same time facilitate cleaning the inside of the fermentation barrel 1, thereby preventing the organic fertilizer remaining in the fermentation barrel 1 from generating odor or attracting mosquitoes and flies, thereby affecting the surrounding environment.

[0033] In some embodiments, a partition 8 is provided at the bottom of the fermentation barrel 1, and a sandwich is formed between the partition 8 and the bottom of the fermentation barrel 1. A heating element 9 is provided in the sandwich. The heating element 9 preferably adopts an electric heating wire, and the heating wire is fixed in the sandwich by bolt connection or binding connection technology in the existing technology. The heating wire is provided with energy heating by an external power supply. The electric heating wire can increase the temperature of the organic fertilizer in the fermentation barrel 1, thereby providing a suitable growth environment for microorganisms. Within the suitable temperature, the activity of microorganisms is enhanced, and the decomposition rate of organic matter is accelerated. At the same time, during the fermentation process, the odor can be greatly reduced, the reproduction of mosquitoes and flies can be reduced, and environmental hygiene can be improved.

[0034] Among them, it is worth noting that the fermentation barrel 1 is preferably made of aluminum, which has excellent thermal conductivity and can quickly and evenly transfer heat to the fermentation barrel 1.

[0035] In some embodiments, a discharge tray 10 is fixedly connected to the bottom of the fermentation barrel 1. The discharge tray 10 has a downward-inclined bottom plate, and side baffles are fixed on both sides of the bottom plate. The organic fertilizer discharged by the scraper 6 is guided by the discharge tray 10 to fall into the container. At the same time, the discharge tray 10 can also be used to receive part of the organic fertilizer that falls from the stirring roller 5 and the stirring blade 7 to prevent it from falling outside and affecting the environment.

[0036] In some embodiments, at least two sets of auxiliary electric push rods 11 are fixed on the left side of the fermentation barrel 1. The auxiliary electric push rods 11 are placed between the fermentation barrel 1 and the left side of the scraper 6. When the sealing cover 2 is manually pulled, since the fermentation barrel 1 is filled with fermented organic fertilizer, manual pulling is relatively laborious. Auxiliary electric push rods 11 are provided to assist in external pulling, thereby saving a certain amount of manpower.

[0037] refer to Figure 3 In some embodiments, at least one set of guide blocks 13 is fixed on the rotating shaft 4, and the guide blocks 13 are the same length as the rotating shaft 4. At least one set of guide grooves 12 is opened in the stirring roller 5, and the guide blocks 13 can be inserted into the guide grooves 12 in a matching manner. When the rotating shaft 4 rotates, the rotating shaft 4 can drive the stirring roller 5 to rotate synchronously through the cooperation between the guide blocks 13 and the guide grooves 12. When discharging is required, the guide grooves 12 can slide along the guide blocks 13 to pull the scraper 6 outward.

[0038] refer to Figure 4 or Figure 5 In some embodiments, the fermentation barrel 1 has an opening on one side, and the fermented organic fertilizer is discharged from the opening. A plurality of threaded holes 15 are opened circumferentially on the outer side of the opening. The sealing cover 2 includes a stepped inner plate and an outer plate. The inner plate is placed in the fermentation barrel 1. The outer plate is provided with a plurality of through holes 16. The outer plate can be equal to the maximum diameter of the fermentation barrel 1 and can fit the opening. The outer plate also includes a plurality of bolts. After the bolts pass through the through holes 16, they can be threadedly connected with the threaded holes 15 to achieve side closure during the fermentation process to prevent leakage and open for discharge when needed.

[0039] In some embodiments, a pull-plate-shaped feed hopper 17 is fixedly connected above the feed port, and the organic fertilizer is gathered through the feed hopper 17 to prevent the fermentation barrel 1 from being scattered during the feeding process and affecting the surrounding environment.

[0040] In some embodiments, several groups of stirring blades 7 are staggered on the stirring roller 5. The stirring blade 7 has a vertical portion and a hook portion at the end of the vertical portion. The staggered stirring blades 7 can achieve more comprehensive and uniform stirring in the fermentation barrel 1, and then the hook portion can be used to lift up part of the organic fertilizer to achieve more sufficient mixing and heating.

[0041] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the utility model.
