[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0035] Referring to Figure 1 and Figure 2 , Figure 1 and Figure 2 An embodiment of the plant residue biodegradation device is shown in the schematic diagram. The embodiment of the application provides a plant residue biodegradation device, which comprises:

[0036] The conveying device 1 is used for conveying plants.

[0037] The cutting mechanism 2 is connected to the discharging side of the conveying device 1. The cutting mechanism 2 comprises a lifting driving mechanism 22 and a cutting blade 21. The lifting driving mechanism 22 is connected to the cutting blade 21 and can drive the cutting blade 21 to ascend or descend.

[0038] The degradation mechanism has a feeding port 3. The discharging side of the cutting mechanism 2 is connected to the feeding port 3.

[0039] Specifically, the conveying device 1 is responsible for conveying the plants, and its discharge side is connected with the feeding side of the cutting mechanism 2, so that the plants can smoothly enter the cutting mechanism 2. The cutting mechanism 2 includes a lifting driving mechanism 22 and a cutting blade 21. The lifting driving mechanism 22 can drive the cutting blade 21 to rise or fall. When the plants reach the appropriate position in the cutting mechanism 2, the blade falls to cut the plants, and after completion, the blade rises. The discharge side of the cutting mechanism 2 is connected with the feeding port 3 of the degradation mechanism, so that the cut plants can be sent into the degradation mechanism for subsequent processing. The three parts in the whole process work closely together to complete the conveying, cutting and subsequent operation of the plants.

[0040] The interval time of the cutting action of the cutting mechanism 2 can be adjusted. The principle is to realize it by controlling the lifting driving mechanism 22. The adjustable time interval setting can flexibly adjust the cutting frequency according to the type, size, quantity of the plants and the requirements of the subsequent degradation process. For example, for thicker or larger plants, the interval time can be appropriately shortened to improve the processing efficiency.

[0041] The conveying device 1 and the cutting mechanism 2 enhance the adaptability of the system to different plant conditions. The conveying device 1 has the performance of carrying a large number of plants to be processed at one time, solves the problem of frequent addition of materials, and improves the convenience of operation. The cutting mechanism 2 can cut a large number of large or long plant residues. The cutting function enables the conveying device 1 to smoothly accommodate a large number of such plant residues.

[0042] Since the operator only needs to work on the slowly running conveying device 1, the possibility of the operator contacting the high-speed running mechanism is greatly reduced, and the safety of the operation process is improved.

[0043] Further, the conveying device 1 includes a conveying belt 15, an anti-overflow structure 11 and a pushing block 12.

[0044] The pushing block 12 is uniformly arranged along the extension direction of the conveying belt 15 of the conveying device 1.

[0045] The anti-overflow structure 11 includes a plurality of anti-overflow plates. Two anti-overflow plates are oppositely arranged on opposite sides of the conveying belt 15. One anti-overflow plate is arranged on the end of the conveying belt 15 away from the cutting mechanism 2.

[0046] Specifically, the conveying device 1 comprises a conveying belt 15, an anti-overflow structure 11 and pushing blocks 12, wherein the pushing blocks 12 are evenly distributed along the extension direction of the conveying belt 15, and the pushing blocks 12 can push the plant materials to move stably forward during the operation of the conveying belt 15, so as to ensure the orderliness of the material conveying. The anti-overflow structure 11 comprises a plurality of anti-overflow plates, two of which are oppositely arranged on the two sides of the conveying belt 15, so as to prevent the plant from falling off from the two sides during the conveying process, and the other anti-overflow plate is arranged at the end of the conveying belt 15 away from the cutting mechanism 2, so as to avoid the overflow of the plant at the end, thereby ensuring that the plant can be smoothly conveyed within the effective range of the conveying belt 15 to the cutting mechanism 2 connected to the discharge side of the conveying belt 15 during the whole conveying process.

[0047] Further, as shown in Figure 3 and Figure 4 , the degradation mechanism further comprises a protective cover 4, which is pivotally connected to the cutting mechanism 2 through a rotating shaft 43, and the protective cover 4 is used to cover above the feeding port 3.

[0048] Specifically, the degradation mechanism further comprises a protective cover 4. The protective cover 4 is pivotally connected to the cutting mechanism 2 through a rotating shaft 43, and the connection mode enables the protective cover 4 to rotate around the rotating shaft 43. The protective cover 4 is used to cover above the feeding port 3 of the degradation mechanism, which can protect the feeding port 3, such as preventing the segmented plant materials from splashing into the external environment to cause safety accidents, and preventing foreign matters from falling into the feeding port 3 to affect the normal processing of the degradation mechanism on the cut plant materials conveyed by the cutting mechanism 2, and also avoiding the operator from accidentally contacting the feeding port 3 during the operation of the equipment.

[0049] Further, the protective cover 4 is a component made of transparent material.

[0050] Specifically, the protective cover 4 is an important component in the degradation mechanism, which is pivotally connected to the cutting mechanism 2 through a rotating shaft 43 and used to cover above the feeding port 3. The protective cover 4 is made of transparent material, and the operator can directly observe the condition of the feeding port 3 through the protective cover 4, such as clearly seeing the process of the cut plant materials entering the feeding port 3, so as to timely find the possible material blockage or other abnormal conditions, that is, while protecting the protective function, the monitoring of the running state of the equipment will not be affected due to the shielding of the sight line.

[0051] Further, the protective cover 4 is a component made of acrylic plate or transparent plastic plate.

[0052] Specifically, the protective cover 4 is made of an acrylic plate or a transparent plastic plate, wherein the acrylic plate has high transparency, high hardness, good weather resistance and the like, and the transparent plastic plate also has good transparency and certain flexibility. Using the two materials to make the protective cover 4 can not only ensure that the operator can clearly observe the feeding port 3 and the material entering condition so as to timely detect possible problems such as material jamming, but also effectively prevent dust, sundries and the like from entering the feeding port 3, and at the same time provide certain safety protection for the operation of the equipment.

[0053] Further, the protective cover 4 is wrapped with an iron frame layer 41 on the outside.

[0054] Specifically, the protective cover 4 is wrapped with an iron frame layer 41 on the outside. For the protective cover 4 made of an acrylic plate or a transparent plastic plate, on the one hand, the iron frame layer 41 can enhance the overall structural strength of the protective cover 4, avoid damage of the protective cover 4 due to external force collision, extrusion and the like, and prolong the service life of the protective cover 4; on the other hand, the iron frame layer 41 can improve the stability of the protective cover 4 to a certain extent, ensure that the protective cover 4 can be stably covered above the feeding port 3 of the degradation mechanism during use, and better play the role of preventing sundries from entering the feeding port 3 and protecting the safety of the operator and the like.

[0055] Further, as shown in Figure 5 , the degradation mechanism further comprises a rotating pushing mechanism 5 and a crushing mechanism 6;

[0056] The rotating pushing mechanism 5 is arranged at the bottom of the feeding port 3 and is used for receiving the objects falling from the feeding port 3. The rotating pushing mechanism 5 comprises a rotating pushing mechanism A 51 and a rotating pushing mechanism B 52. A plurality of protrusions are uniformly arranged on the rotating pushing mechanism A 51 and the rotating pushing mechanism B 52, and the protrusions in contact with each other are matched with each other.

[0057] The crushing mechanism 6 is located directly below the position where the rotating pushing mechanism A 51 and the rotating pushing mechanism B 52 are in contact. The crushing mechanism 6 comprises a knife shaft, and a plurality of blades are arranged on the knife shaft.

[0058] Specifically, the degradation mechanism is further provided with a rotating pushing mechanism 5 and a crushing mechanism 6. The rotating pushing mechanism 5 is located at the bottom of the feeding port 3 and is used to catch the objects falling from the feeding port 3. The rotating pushing mechanism 5 is composed of a rotating pushing mechanism A 51 and a rotating pushing mechanism B 52. Both of them have multiple protrusions uniformly distributed, and the protrusions in contact with each other can fit with each other. This design helps better handle the objects received. The crushing mechanism 6 is located directly below the contact position of the rotating pushing mechanism A 51 and the rotating pushing mechanism B 52. The crushing mechanism 6 includes a knife shaft, and multiple blades are arranged on the knife shaft. When the rotating pushing mechanism 5 pushes the objects to this position, the crushing mechanism 6 uses the blades to crush the objects, thereby preparing for the subsequent degradation process. It can be understood that the rotating pushing mechanism 5 can also use the existing relative pressure roller assembly, that is, composed of two rolling rollers. The chopping mechanism can also use mature chopping equipment.

[0059] Further, a degradation tank is arranged below the crushing mechanism 6, and a stirring mechanism 7 is arranged in the degradation tank. The stirring mechanism 7 includes stirring blades 72, a stirring motor 71 and a stirring rotating shaft 74. The stirring motor 71 is located outside the degradation tank, and the stirring rotating shaft 74 is located inside the degradation tank. The stirring motor 71 and the stirring rotating shaft 74 are drivingly connected, and the stirring motor 71 provides power for the stirring rotating shaft 74.

[0060] Specifically, a degradation tank is arranged below the crushing mechanism 6, and a stirring mechanism 7 is arranged in the degradation tank. The stirring mechanism 7 includes stirring blades 72, a stirring motor 71 and a stirring rotating shaft 74. The stirring motor 71 is located outside the degradation tank, and the stirring rotating shaft 74 is located inside the degradation tank. The stirring motor 71 and the stirring rotating shaft 74 are drivingly connected, and the stirring motor 71 provides power for the stirring rotating shaft 74. The stirring rotating shaft 74 is uniformly distributed with multiple stirring blades 72. The stirring blades 72 are curved or inclined in shape. When the stirring motor 71 drives the stirring rotating shaft 74 to rotate, the stirring blades 72 rotate, and the material crushed by the crushing mechanism 6 is stirred in the degradation tank. The special-shaped stirring blades 72 can more effectively stir the material and prevent the material from adhering to the stirring blades 72, so that the material is more fully mixed in the degradation tank, which is beneficial to the degradation reaction of the material in the degradation tank.

[0061] The stirring motor 71 has the ability to drive the rotating shaft 43 to rotate forward and reverse. Through this forward and reverse rotation, the material can be effectively prevented from accumulating on one side of the degradation tank, so that the material can be uniformly distributed in the degradation tank, and the degradation process can be smoothly and efficiently carried out.

[0062] Further, the degradation tank is provided with a degradation liquid spraying mechanism on the side parallel to the stirring rotation shaft 74. The degradation liquid spraying mechanism comprises a degradation liquid spraying head 8 arranged inside the degradation tank and a degradation liquid tank 81 arranged outside the degradation tank. The degradation liquid spraying head 8 is connected to the degradation liquid tank 81 through a water pump.

[0063] Specifically, the degradation liquid spraying mechanism is arranged on the side of the degradation tank parallel to the stirring rotation shaft 74. The mechanism mainly comprises two parts, one part is the degradation liquid spraying head 8 arranged inside the degradation tank, and the other part is the degradation liquid tank 81 arranged outside the degradation tank. The two parts are connected through a water pump. The water pump can extract and deliver the degradation liquid in the degradation liquid tank 81 to the degradation liquid spraying head 8, so that the degradation liquid spraying head 8 can spray the degradation liquid in the degradation tank, and cooperate with the stirring action of the stirring rotation shaft 74 to make the degradation liquid fully contact with the material, which is conducive to the plant residue degradation reaction.

[0064] Further, the stirring blade 72 is further provided with a heating plate 73. The heating plate 73 is used to adjust the temperature in the degradation tank.

[0065] Specifically, the heating plate 73 is arranged on the stirring blade 72. During the degradation process, the heating plate 73 can play an important role. They can adjust the temperature in the degradation tank through the heat generated. When the degradation reaction has specific requirements for temperature, the heating plate 73 can ensure that the temperature in the degradation tank is in the appropriate range, and cooperate with the stirring action of the stirring blade 72 to make the temperature in the degradation tank more uniform and stable, which creates more favorable conditions for the degradation reaction of the material in the degradation tank.

[0066] In another embodiment, a temperature sensing mechanism is further arranged on the side of the degradation tank parallel to the stirring rotation shaft 74. The temperature sensing mechanism comprises a temperature sensor arranged inside the degradation tank and an electric control box arranged outside the degradation tank. The temperature sensor is in an electrically connected state with the electric control box. The temperature sensor is used to measure and obtain the temperature in the degradation tank in real time.

[0067] In another embodiment, the degradation liquid tank 81 is provided with an opening. Through the opening, the user can add or replace the degradation liquid in the degradation liquid tank 81. In addition, the user can use targeted degradation liquid according to the degradation characteristics of different plants, so as to better meet the needs of different plant residue biodegradation and ensure the efficiency and effectiveness of the degradation process.
