Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figure 1 and Figure 3, An embodiment provided by the present utility model: a garden waste microbial degradation device, which includes a degradation box 1. A second box door 6 is hinged to the upper side of the left end of the degradation box 1, a first box door 5 is hinged to the lower side of the left side of the degradation box 1, an observation window 4 is arranged at the front end of the degradation box 1, a feed cover 2 is hinged to the left side of the top of the degradation box 1, a support plate 12 is fixedly connected to the left side of the inner wall of the degradation box 1, a filter plate 10 is fixedly connected to the top of the support plate 12 for filtering small particle stones contained in garden waste. A collection box 11 is arranged at the left side of the top of the support plate 12. The left end of the filter plate 10 is fixedly connected to the left side of the inner wall of the degradation box 1. An installation shell 13 is fixedly connected to the bottom end of the support plate 12. A driving motor 3 is fixedly connected to the right side of the top of the degradation box 1. A cutting component is arranged at the driving end of the driving motor 3 for cutting garden waste. The cutting component includes a rotating shaft 17 fixedly connected to the driving end of the driving motor 3, and a plurality of cutting knives 18 are fixedly connected to the outer wall of the rotating shaft 17. A guiding block 16 is fixedly connected to the right side of the inner wall of the degradation box 1, and a limiting track 14 is fixedly connected to the bottom of the inner wall of the degradation box 1. A degradation box 15 is arranged on the outer wall of the limiting track 14;

[0027] Specifically, pull the handle on the feed cover 2 to pour garden waste into the interior of the degradation box 1. After the waste enters the interior of the degradation box 1, it first falls onto the surface of the filter plate 10. At this time, the large pieces of waste will slide to the right under the action of gravity, while the small particle stones mixed in the waste will fall into the collection box 11 through the filter holes on the filter plate 10 for collection. After the waste slides to the right, it will be cut by the cutting knives 18 driven by the driving motor 3 in cooperation with the rotating shaft 17, and the waste will be cut into small pieces to facilitate the contact between microorganisms and the waste, improving the degradation rate. The cut waste will fall into the degradation box 15 under the guidance of the guiding block 16 for degradation. After the degradation is completed, the first box door 5 and the second box door 6 can be pulled to take out the collection box 11 and the degradation box 15 from the degradation box 1, and the stones and the degraded residues inside are processed.

[0028] Refer to Figure 3 and Figure 4 , a suction fan 19 is fixedly connected to the bottom of the inner wall of the installation shell 13, and a filter screen 20 is fixedly connected to the right end of the installation shell 13 for sucking the gas generated by the microbial degradation of garden waste. The air outlet end of the suction fan 19 is fixedly connected to an air delivery pipe 21. One side of the outer wall of the air delivery pipe 21 penetrates through the rear end of the installation shell 13, the other side of the air delivery pipe 21 penetrates through the rear end of the degradation box 1, and the other end of the air delivery pipe 21 is fixedly connected to a rotary joint pipe 8. The other end of the rotary joint pipe 8 is fixedly connected to an air injection pipe 9, and the air injection pipe 9 can inject the gas into a gas collecting bottle for transfer and treatment;

[0029] Specifically, during the degradation process, the exhaust fan 19 can be started to collect the gases generated by degradation. These gases are sent through the gas pipeline 21 and the adapter 8 to the air injection pipe 9, and then the air injection pipe 9 is connected to the gas collecting bottle to collect and process the gases, avoiding accidents caused by toxic or combustible gases doped in the gases. At the same time, the peculiar smell generated by degradation inside the degradation tank 1 can be removed as much as possible. The filter screen 20 provided at the right end of the installation shell 13 can prevent the residues generated by degradation from being sucked into the exhaust fan 19 during the gas extraction process and damaging the exhaust fan 19.

[0030] Refer to Figure 2 and Figure 5 A balance pipe 7 is penetrated through the right side of the rear end of the degradation tank 1. A connecting block 22 is fixedly connected to the inner wall of the balance pipe 7. A spring cylinder 23 is fixedly connected to the front end of the connecting block 22. A baffle 24 is fixedly connected to the front end of the spring cylinder 23. A sealing ring is provided at the rear end of the baffle 24.

[0031] Specifically, when extracting the gases inside the degradation tank 1, the air pressure inside the degradation tank 1 may be too low, making it difficult to open the first box door 5 and the second box door 6 during subsequent cleaning of the inside of the degradation tank 1. Through the setting of the balance pipe 7, the air pressure inside the degradation tank 1 can be balanced. When the air pressure inside the degradation tank 1 is too low, the outside air will push the baffle 24 and stretch the spring cylinder 23, causing the baffle 24 to move away from the balance pipe 7 to generate a gap and allowing the outside air to pour into the degradation tank 1 until the internal and external air pressures are balanced. At this time, the baffle 24 will reset under the elastic force of the spring cylinder 23, and the sealing ring at its rear end will contact the balance pipe 7 to prevent the gases inside the degradation tank 1 from leaking and harming the environment.

[0032] Working principle: Pull the handle on the feeding cover 2 to pour garden waste into the degradation box 1. After the waste enters the degradation box 1, it first falls onto the surface of the filter plate 10. At this time, the large pieces of waste will slide to the right under the action of gravity, while the small particle stones mixed in the waste will fall into the collection box 11 through the filter holes on the filter plate 10 for collection. After the waste slides to the right, it will be cut by the cutting knife 18 driven by the driving motor 3 in cooperation with the rotating shaft 17, cutting the waste into small pieces to facilitate the contact between microorganisms and the waste and improve the degradation rate. The cut waste will fall into the degradation box 15 under the guidance of the guiding block 16 for degradation. After the degradation is completed, the first box door 5 and the second box door 6 can be pulled to take out the collection box 11 and the degradation box 15 from the degradation box 1 to process the stones and the degraded residues inside. During the degradation process, the gas generated by degradation can be collected by starting the exhaust fan 19, sent to the air injection pipe 9 through the air delivery pipe 21 and the adapter pipe 8, and then the air injection pipe 9 is connected to the gas collecting bottle to collect and process the gas, avoiding accidents caused by toxic or combustible gases doped in the gas, and at the same time, the peculiar smell generated by degradation inside the degradation box 1 can be removed as much as possible. The filter screen 20 arranged at the right end of the installation shell 13 can prevent the residues generated by degradation from being sucked into the exhaust fan 19 during the gas extraction process and causing damage to the exhaust fan 19. When extracting the gas inside the degradation box 1, it may cause the air pressure inside the degradation box 1 to be too low, making it difficult to open the first box door 5 and the second box door 6 when cleaning the inside of the degradation box 1 later. Through the setting of the balance pipe 7, the air pressure inside the degradation box 1 can be balanced. When the air pressure inside the degradation box 1 is too low, the outside air will push the baffle 24 and stretch the spring cylinder 23, causing the baffle 24 to move away from the balance pipe 7 to generate a gap and pour the outside air into the degradation box 1 until the internal and external air pressures are balanced. At this time, the baffle 24 will reset under the elastic force of the spring cylinder 23, and the sealing ring at its rear end will contact the balance pipe 7 to prevent the gas inside the degradation box 1 from leaking and harming the environment.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
