[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

[0033] This application provides a fermentation device, which is applied to the fermentation of livestock and poultry manure. In one embodiment, please refer to Figure 1 , the fermentation device includes a tank body 10, a scraping structure 20, and a driving member 30.

[0034] Among them, the tank body 10 can accommodate the substances to be fermented. Specifically, the tank body 10 has a fermentation cavity 110 for accommodating the substances to be fermented, and the substances to be fermented can be accommodated in the fermentation cavity 110. It should be noted that the shape and size of the fermentation cavity 110 are not limited. In application, in order to enable the substances to be fermented to be fully filled in the fermentation cavity 110 along the extension path of the fermentation cavity 110, the shape of the fermentation cavity 110 is generally set to a regular shape. For example, the cross-section of the fermentation cavity 110 is set to be circular or rectangular. In the embodiments of this application, the cross-section of the fermentation cavity 110 may be set to be circular, that is, the shape of the fermentation cavity 110 is set to be cylindrical. It can be understood that when the fermentation cavity 110 is cylindrical, the inner wall that needs to be scraped and cleaned is the circumferential wall of the fermentation cavity 110 around its central axis.

[0035] The scraping structure 20 is movably connected to the tank body 10, and the scraping structure 20 is located in the fermentation cavity 110. The scraping structure 20 has a scraping edge 227, and the scraping edge 227 can abut against the cavity wall of the fermentation cavity 110.

[0036] The driving member 30 is arranged on the tank body 10. For example, as shown in Figure 1 , the driving member 30 is arranged on the tank body 10 and is located outside the fermentation cavity 110. The driving member 30 can drive the scraping structure 20 to move, so as to drive the scraping edge 227 to move along the inner wall of the fermentation cavity 110.

[0037] It can be understood that when using the driving member 30 to drive the scraping edge 227 to clean the inner wall of the fermentation cavity 110, in order to clean it thoroughly enough, the scraping edge 227 has at least two scraping methods. One scraping method is that the scraping edge 227 can extend along the axis of the fermentation cavity 110, and the driving member 30 can drive the scraping edge 227 to rotate around the rotating shaft of the fermentation cavity 110 to scrape the sundries on the inner wall of the fermentation cavity 110 clean; the other scraping method is to arrange the scraping edge 227 around the axis of the fermentation cavity 110, and the driving member 30 can drive the scraping edge 227 to move along the axis of the fermentation cavity 110, so as to scrape the inner wall of the fermentation cavity 110 clean.

[0038] As can be seen from the above, for the fermentation device provided in this application, a scraping structure 20 is provided inside its fermentation chamber 110. The scraping structure 20 includes a scraping blade 227, and the scraping blade 227 can abut against the inner wall of the fermentation chamber 110. When it is necessary to clean the inner wall of the fermentation chamber 110, the driving member 30 can be used to drive the scraping structure 20 to move, so as to drive the scraping blade 227 to move along the inner wall of the fermentation chamber 110, and then the adhesives on the inner wall of the fermentation chamber 110 can be scraped off. The solution of this application does not require manual cleaning. The driving member 30 is used to drive the scraping blade 227 to clean the adhesives on the inner wall of the fermentation chamber 110, which saves manpower and significantly improves the efficiency compared with manual cleaning.

[0039] In one embodiment, please refer to Figure 1 , the outer shape of the tank body 10 is not limited. In order to ensure that the tank body 10 can be stably placed, a plurality of support members 140 are provided on the tank body 10. One end of the support member 140 can be fixedly connected to the tank body 10 by welding or by screws, and the other end of the support member 140 is used to support on the placement table. The plurality of support members 140 are arranged at intervals, and the arrangement manner between the plurality of support members 140 needs to be sufficient to support the tank body 10. For example, the plurality of support members 140 can be arranged in a polygonal structure.

[0040] In addition, in order to be able to fill the fermentation chamber 110 with the material to be fermented, a feed inlet 120 is provided at one end of the tank body 10, and a discharge outlet 130 is provided at the other end of the tank body 10. Both the feed inlet 120 and the discharge outlet 130 communicate with the fermentation chamber 110. The material to be fermented can enter the fermentation chamber 110 from the feed inlet 120, and the fermented material can be discharged from the fermentation chamber 110 through the discharge outlet 130.

[0041] It is worth mentioning that the position of the discharge outlet 130 relative to the tank body 10 is lower than the position of the feed inlet 120 relative to the tank body 10, that is, when the tank body 10 is placed at the placement position, the feed inlet 120 is located at the upper end of the tank body 10, and the discharge outlet 130 is located at the lower end of the tank body 10. Thus, the material to be fermented can be smoothly put into the fermentation chamber 110, and the fermented material can be conveniently discharged from the discharge outlet 130.

[0042] In one possible embodiment, please refer to Figure 1, a method of driving the scraping member 220 to rotate to clean the inner wall of the fermentation chamber 110 is adopted. Specifically, the scraping structure 20 includes a mounting member 210 rotatably connected to the tank body 10. A scraping member 220 is provided on the mounting member 210, and a scraping edge 227 is provided on the scraping member 220. The rotating shaft of the mounting member 210 and the central axis of the fermentation chamber 110 are coaxially arranged, so that when the mounting member 210 rotates, it can drive the scraping edge 227 to rotate around the central axis of the fermentation chamber 110, and the scraping edge 227 extends along the central axis of the fermentation chamber 110. The length of the scraping edge 227 is the same as the dimension of the fermentation chamber 110 along its central axis. In this way, when the scraping edge 227 rotates one week, the adhesives on the peripheral wall of the fermentation chamber 110 can be scraped clean.

[0043] Since the fermentation chamber 110 is located inside the tank body 10, when manually cleaning the inner wall of the fermentation chamber 110, the hand often reaches into the fermentation chamber 110 from the feed inlet 120 or the discharge outlet 130 for cleaning. Such a cleaning method often has cleaning dead corners where the hand cannot reach, which easily leads to incomplete cleaning. By extending the scraping edge 227 along the central axis direction of the fermentation chamber 110 and adapting the length of the scraping edge 227 to the length of the fermentation chamber 110 on the central axis, when driving the scraping edge 227 to rotate, it can scrape the adhesives on the entire peripheral wall of the fermentation chamber 110, making the cleaning without dead corners and more thorough.

[0044] In a possible implementation manner, the mounting member 210 includes two connecting portions 214 arranged at intervals. The mounting member 210 further includes a scraping portion 215 connected between the two connecting portions 214. The connecting portion 214 is rotatably connected to the tank body 10, and the scraping member 220 is connected to the scraping portion 215.

[0045] In order to make the scraping portion 215 receive a uniform reaction force during scraping, the scraping portion 215 is arranged along the central axis of the fermentation chamber 110, and the scraping portion 215 may be set to a regular shape, such as a cylindrical shape or a rectangular shape.

[0046] A rotating shaft (not shown in the figure) is connected to the connecting portion 214. The connecting portion 214 can be connected to the tank body 10 through the rotating shaft. In particular, a bearing is provided at the connection position of the tank body 10 and the rotating shaft. The outer ring of the bearing is fixedly connected to the tank body 10, and the inner ring of the bearing is fixedly connected to the rotating shaft, so that the connecting portion 214 can be rotatably connected to the tank body 10.

[0047] Driving the connecting portion 214 to rotate can drive the scraping portion 215 to rotate. There is a certain angle between the connecting portion 214 and the scraping portion 215. The specific angle is not limited here, but in order to make the transmission of the driving force more sufficient when driving the scraping portion 215 to rotate, the angle between the connecting portion 214 and the scraping portion 215 may be set to a right angle.

[0048] It should be noted that both connecting parts 214 are rotatably connected to the tank body 10. Therefore, the driving member 30 only needs to drive one of the connecting parts 214 to rotate. In this embodiment, the driving member 30 may be a driving motor, and the output end of the driving motor is coaxially connected to the rotating shaft to drive the entire mounting member 210 to rotate.

[0049] Of course, in another embodiment, the driving member 30 can also be used to drive the scraping member 220 to reciprocate along the central axis of the fermentation chamber 110 to clean the fermentation chamber 110. In this method, the output end of the driving member 30 can be coaxially connected with a lead screw, and a nut that can be threadedly connected to the lead screw is installed on the mounting member 210. The driving member 30 can drive the lead screw to rotate, and when the lead screw rotates, the nut can move along the central axis of the fermentation chamber 110, thereby driving the mounting member 210 to move along this direction.

[0050] In the fermentation device of the present application, a plurality of scraping structures 20 can be arranged at intervals in the tank body 10. The number of scraping structures 20 is not limited and can be two, three or more. For example, in the present application, when the scraping structure 20 is rotatably connected to the tank body 10, two scraping structures 20 are arranged at equal intervals around the central axis of the fermentation chamber 110. The two scraping structures 20 are connected together through the connecting part 214, specifically, they are fixedly connected through the end of the connecting part 214 away from the scraping part 215, and the rotating shaft is connected in the middle of the two connected connecting parts 214. The angle between the two scraping structures 20 is not limited. In the embodiment of the present application, the included angle between the two scraping structures 20 is set to 180 degrees. By arranging a plurality of scraping structures 20, the plurality of scraping structures 20 can act on the inner wall of the fermentation chamber 110 together to clean the inner wall of the fermentation chamber 110 together, thereby increasing the cleaning efficiency.

[0051] In a specific embodiment, please refer to Figure 1 and Figure 2 , the scraping member 220 has a plurality of end faces, and a corresponding structure can be formed by enclosing between the plurality of end faces. For example, the scraping member 220 includes a material guiding surface 221 and a material backing surface 222. Both the material guiding surface 221 and the material backing surface 222 extend along the central axis of the fermentation chamber 110. One end of the material guiding surface 221 and the material backing surface 222 can be arranged at intervals and can be connected to the end face of the scraping part 215, and the other end of the material guiding surface 221 and the material backing surface 222 can be connected together. An included angle is formed at the connection between the material guiding surface 221 and the material backing surface 222, so that the connection position of the material guiding surface 221 and the material backing surface 222 forms a scraping edge 227.

[0052] The scraping structure 20 can rotate clockwise or counterclockwise around the central axis of the fermentation chamber 110 under the drive of the driving member 30, as Figure 1The direction of the arrow shown is the direction of rotation. Among them, the direction of rotation from X to Y is defined as the clockwise direction, and the direction of rotation from Y to X is defined as the counterclockwise direction.

[0053] The material guiding surface 221 is arranged to face the reverse direction of the rotation when the scraping blade 227 cleans the inner wall of the fermentation cavity 110, and the material backing surface 222 just faces away from this direction. For example, if the scraping blade 227 rotates clockwise in the fermentation cavity 110 as the rotation direction when cleaning the inner wall of the fermentation cavity 110, then the material guiding surface 221 faces this direction.

[0054] The material guiding surface 221 can guide the sticky substances scraped from the inner wall of the fermentation cavity 110 back to the fermentation cavity 110. The material guiding surface 221 can be a curved surface or an inclined surface inclined relative to the end face of the scraping part 215. When the scraping blade 227 rotates to scrape the sticky substances, the scraping blade 227 will also be subject to the reaction force of the sticky substances. In order to increase the strength of the scraping blade 227, the material backing surface 222 can be arranged to be bent away from the material guiding surface 221, or bent away from the material guiding surface 221 at the middle position of the material backing surface 222.

[0055] In addition, since the scraping blade 227 abuts against the inner wall of the fermentation cavity 110, the inner wall of the fermentation cavity 110 can be cleaned when it rotates clockwise or counterclockwise.

[0056] In one embodiment, please refer to Figures 1 to 4 , the scraping member 220 can be fixedly connected to the scraping part 215 or movably connected to the scraping part 215. When the scraping member 220 is movably connected to the scraping part 215, it can clean the inner wall of the fermentation cavity 110 when rotating in one direction, and when rotating in the other direction, it can prevent jamming or avoid interfering with the stirring of the material to be fermented by the stirring structure 40 in the following text.

[0057] Specifically, a bracket 213 is arranged on the scraping part 215, and the scraping member 220 is rotatably connected to the bracket 213. The scraping member 220 has a scraping position and a retracted position relative to the scraping part 215. It should be noted here that the rotation axis of the scraping member 220 is arranged parallel to the central axis of the fermentation cavity 110. In this way, when the scraping member 220 is in the retracted position, the scraping blade 227 can be separated from the inner wall of the fermentation cavity 110, and when the scraping member 220 is in the scraping position, the scraping blade 227 abuts against the inner wall of the fermentation cavity 110.

[0058] By movably arranging the scraping member 220, and the scraping member 220 has a scraping position and a retracted position, when the inner wall of the fermentation cavity 110 needs to be scraped, the scraping member 220 is set to the scraping position, and when it is necessary to retract the tool to avoid jamming, the scraping member 220 can be moved to the retracted position.

[0059] In a specific embodiment, the scraper 220 further includes two side surfaces 224 and an action surface 223 . The two side surfaces 224 are spaced apart and arranged along the length direction of the scraper 220 . The scraper 220 is rotatably connected to the bracket 213 via the side surfaces 224 .

[0060] When the scraper 220 is connected to the bracket 213, the action surface 223 is arranged toward the scraper portion 215, one end of the action surface 223 is connected to the guide surface 221, and the other end is connected to the backing surface 222, and a yielding portion 226 is formed between one end of the action surface 223 and the guide surface 221, and a contact portion 225 is formed between the other end of the action surface 223 and the backing surface 222. An elastic member is also connected between the scraper 220 and the bracket 213, and in a free state, the elastic member forces the contact portion 225 to contact the mounting member 210, so that the scraper 220 is located at the scraping position.

[0061] It should be noted that, in this embodiment, when the scraper 220 rotates clockwise (see the rotation from X to Y in the above text), the inner wall of the fermentation chamber 110 can be cleaned, and when the scraper 220 rotates counterclockwise, the scraper 220 can give way. In this application, the giving way portion 226 is rounded, and the giving way portion 226 can be tangent to the end surface of the scraper portion 215.

[0062] When the scraper 220 is driven to rotate counterclockwise, if there is a sticky object protruding from the inner wall of the fermentation chamber 110 on the rotation path of the scraper 220, when the scraper 220 touches the sticky object, the scraper 220 has a tendency to rotate relative to the scraper portion 215, and the yielding portion 226 is set on the rotation path of the scraper 220, so that the scraper 220 can rotate relative to the scraper portion 215, so that the scraper 220 can smoothly avoid the sticky object.

[0063] When the scraper 220 is driven to rotate clockwise, the scraper 220 is subjected to a reaction force when scraping off sticky materials, so that it has another tendency to rotate relative to the scraper portion 215, and the rotation direction of the rotation tendency is opposite to the rotation direction of the scraper 220 relative to the scraper portion 215 mentioned above. The abutment portion 225 is located on the rotation path of the scraper 220, and because the abutment portion 225 abuts against the scraper portion 215, the abutment portion 225 can prevent the scraper 220 from rotating relative to the scraper portion 215, so that the scraper 220 can smoothly perform the scraping operation on the inner wall of the fermentation chamber 110.

[0064] In another specific embodiment, two side surfaces 224 of the scraper 220 are arranged opposite to the bracket 213, and the side surfaces 224 are rotatably connected to the bracket 213 through a connecting member, and at least two positioning holes 2241 are arranged at intervals on the side surfaces 224, and the two positioning holes 2241 are arranged around the rotating shaft of the scraper 220. A limiting hole 2131 is provided on the bracket 213, and the scraper 220 can be rotated to a scraping position and a retracted position. When the scraper 220 is rotated to the scraping position, one of the positioning holes 2241 can be arranged opposite to the limiting hole 2131, and when the scraper 220 is rotated to the retracted position, the other positioning hole 2241 can be opposite to the limiting hole 2131. The positioning hole 2241 and / or the limiting hole 2131 are threaded holes. When the positioning hole 2241 and the limiting hole 2131 are opposite to each other, the purpose of fixing the scraper 220 can be achieved by inserting screws into the positioning hole 2241 and the limiting hole 2131.

[0065] In one possible embodiment, please refer to Figure 1 and Figure 5 If some sticky materials adhere to the inner wall of the fermentation chamber 110 for a long time and are tightly bonded, they are not easy to be scraped off. In this case, they need to be wetted first and then cleaned with the scraper 220 after softening.

[0066] Therefore, in this embodiment, a water delivery channel 211 is provided in the mounting part 210, specifically, the water delivery channel 211 is provided inside the connecting part 214 and the scraping part 215, and the two ends of the water delivery channel 211 in the scraping part 215 can be respectively connected with the water delivery channel 211 in the connecting part 214. The scraping part 215 is provided with a water spray hole 212 connected to the water delivery channel 211, and the water spray hole 212 is provided on the end surface of the scraping part 215 facing the inner wall of the fermentation chamber 110. The tank body 10 is also provided with a flushing structure 50, which mainly includes a water storage tank 510 and a water delivery member 520, wherein the water delivery member 520 can be a water pump, the water inlet end of the water pump can be connected to the water storage tank 510, and the water outlet end of the water pump can be connected to the water delivery channel 211 through a water pipe. The water pump can extract water from the water storage tank 510 and transport it to the water delivery channel 211, and can spray it out through the water spray hole 212. The water flow can be sprayed onto the inner wall of the fermentation chamber 110 to achieve the purpose of infiltrating sticky substances.

[0067] It should be noted that in order to avoid the water pipe from getting entangled when the scraper structure 20 rotates, a connecting channel is coaxially opened on the rotating shaft connecting the connecting part 214 and the tube body. The water outlet of the water pump is connected to the connecting channel through a water pipe, and the connecting channel is connected to the water supply channel 211. In this way, when the rotating shaft rotates, the water pipe can rotate coaxially without getting entangled.

[0068] In one embodiment, see Figure 1, in order to evenly collect the material to be fermented in the fermentation chamber 110 and to be able to drive the fermented material to move towards the discharge port 130, the fermentation device of the present application further includes a stirring structure 40 disposed in the fermentation chamber 110. The stirring structure 40 includes a stirring shaft 410 and stirring blades 420. The stirring blades 420 are connected to the stirring shaft 410, and the stirring shaft 410 is rotatably connected to the tank body 10.

[0069] Specifically, the rotation axis of the stirring shaft 410 and the rotation axis of the scraping structure 20 are coaxially arranged, that is, the stirring shaft 410 is coaxially arranged with the rotating shaft between the connecting portion 214 and the tank body 10. In order to simplify the structure, the two ends of the stirring shaft 410 are directly connected to the two connecting portions 214. The stirring blades are arranged on the peripheral wall of the stirring shaft 410 and extend along the axis of the stirring shaft 410. The stirring blades are spirally arranged along their extending direction. The stirring shaft 410 and the stirring blades can rotate together with the scraping structure 20, and the stirring blades can drive the material to be fermented in the fermentation chamber 110 to move towards the discharge port 130 during the rotation process.
