The hopper 201 is arranged on the top of the fermentation tank 101 and is connected to the feed cavity 102. The top plate 202 is fixedly arranged on the top of the hopper 201; a feeding mechanism 3, the feeding mechanism 3 includes an upper cone block 301, a column 302 and a lower cone block 307. The upper cone block 301 is slidably arranged in the feed cavity 102, and the column 302 is arranged in the middle of the upper cone block 301. One end of the column 302 is aligned with the upper cone block 301. The shaft is fixedly connected, the other end of the column 302 is slidably inserted on the top plate 202, the lower cone block 307 is slidably set in the feed cavity tube 102 and arranged on one side of the bottom of the upper cone block 301; the driving mechanism 4, the driving mechanism 4 includes a driver 401, a driving disk 402, a driving column 403 and a lifting cylinder 404, the driver 401 is set at one end of the fermentation tank 101, one end of the driving disk 402 is connected to the driver 401, and the other end of the driving disk 402 is connected to the It is connected to a driving column 403, which is rotatably arranged in the inner cavity of the fermentation tank 101. A lifting cylinder 404 is also slidably arranged on the driving column 403, and the lifting cylinder 404 is rotatably assembled at the bottom of the lower cone block 307; the feeding mechanism 3 also includes a lower cone surface 303 and an upper cone surface 308, the lower cone surface 303 is arranged at the bottom of the upper cone block 301, and the upper cone surface 308 is arranged at the top of the lower cone block 307, and the lower cone surface 303 and the upper cone surface 308 are matched.

[0026] In actual application of this embodiment, when the device is used for biological fermentation of kitchen waste, the fermentation tank 101 is used to ferment the loaded kitchen waste, and the hopper 201 is used to load the kitchen waste to be processed. The driver 401 can drive the driving disc 402 to rotate on a fixed axis in the driving state, and the driving disc 402 can synchronously drive the driving column 403 to rotate during the rotation process. During the movement of the driving column 403, the lifting cylinder 404 slidably assembled thereon can reciprocate in the vertical direction under the driving action, and the lifting cylinder 404 moves vertically toward one side of the feeding cavity tube 102. When the upper and lower cone blocks 301 and 307 are in a closed position, the lower cone block 307 is pressed against the bottom of the upper cone block 301, and the upper cone block 301 and the column bar 302 are elastically slidably assembled on the bottom of the top plate 202, so that the distance between the upper and lower cone blocks 301 and 307 is continuously shortened. In this process, the gas between the upper and lower cone blocks 301 and 307 is squeezed out. When the upper and lower cone blocks 301 and 307 are tightly fitted, the lower cone block 307 synchronously presses the upper cone block 301 to move in the vertical direction, and the upper cone block 301 overcomes the elastic force and slides. When the upper cone block 301 slides vertically to one side of the feed cavity tube 102, the upper cone block 301 is clamped on one end of the top plate 202. When the lower cone block 307 slides in the opposite direction under the traction, an annular cavity is formed between the upper cone block 301 and the lower cone block 307, so that the kitchen waste stored in the hopper 201 can flow into the cavity of the upper cone block 301 and the lower cone block 307. Since a plurality of sliding pins 309 are arranged on the top of the lower cone block 307, and the sliding pins 309 are limitedly slidably inserted on the upper cone block 301, the lower cone block 307 can pull the upper cone block 301 in the process of reverse movement. 01 moves in the opposite direction synchronously, so that the upper cone block 301 slides into the feeding cavity tube 102 again, and when the lower cone block 307 pulls the upper cone block 301 to move to the bottom side of the feeding cavity tube 102, the kitchen waste in the cavities of the upper cone block 301 and the lower cone block 307 falls into the inner cavity of the fermentation tank 101 under the action of gravity, so that the kitchen waste can be continuously input into the fermentation tank 101 for fermentation without opening the fermentation tank 101, and during the input of the kitchen waste, the inner cavity of the fermentation tank 101 is always sealed from the external atmospheric environment to prevent the fermentation gas generated in the fermentation tank 101 from escaping.

[0027] In one case of the present embodiment, an independent exhaust port 104 is further provided on one side of the fermentation tank 101, an independently controlled butterfly valve is installed on the exhaust port 104, and the exhaust pipe port side is connected to a gas tank and / or processing equipment for storing fermentation gas, which will not be described in detail here.

[0028] In one case of this embodiment, the upper cone block 301 and the lower cone block 307 are connected to the inner cavity of the feed cavity tube 102 in a sliding and sealing manner by default, which will not be described in detail here.

[0029] See also Figure 5 In a preferred embodiment of the present invention, the fermentation tank assembly 1 further includes a tail pipe 105 and an air leakage hole 106. The tail pipe 105 is arranged at the bottom of the feed cavity 102 and is coaxially arranged with the feed cavity 102. A plurality of air leakage holes 106 are also arranged on the tail pipe 105.

[0030] In actual application of this embodiment, when the lower cone block 307 moves vertically upward, the upper cone block 301 is located on the bottom side of the tail pipe 105, and when the upper cone surface 308 is pressed against the side of the lower cone surface 303, the gas between the upper cone block 301 and the lower cone block 307 can pass through the vent hole 106 and return to the inner cavity of the fermentation tank 101. During the process of the upper cone block 301 rising along the tail pipe 105, the lower cone block 307 and the upper cone block 301 are completely sealed and fitted to prevent the gas in the inner cavity of the fermentation tank 101 from escaping.

[0031] See also Figure 3 In a preferred embodiment of the present invention, the feed tray assembly 2 also includes a chassis 203 and a slot 204, the chassis 203 is fixedly arranged at the bottom of the top plate 202, and the inner wall side of the chassis 203 is provided with a slot 204, the feeding mechanism 3 also includes a clamping plate 304, a limiting plate 305 and an elastic member 306, the clamping plate 304 is fixedly arranged on the column bar 302, and the clamping plate 304 is arranged between the upper cone block 301 and the chassis 203, the limiting plate 305 is fixedly arranged on the column bar 302 and arranged at one end of the top plate 202, and the elastic member 306 is elastically assembled between the clamping plate 304 and the top plate 202.

[0032] When the upper cone block 301 is pressed toward the top plate 202 by the lower cone block 307, the column bar 302 slides synchronously in the top plate 202, and the snap-in plate 304 on the column bar 302 is pressed into the snap-in groove 204 at the bottom of the chassis 203 during the movement, so that the snap-in plate 304 is snapped and embedded in the snap-in groove 204. At this time, the elastic member 306 is in an energy storage state. When the lower cone block 307 pulls the lower cone block 307 to move in the opposite direction, the snap-in plate 304 on the column bar 302 slips out of the snap-in groove 204 after being stressed. At this time, the elastic potential energy of the elastic member 306 acts on one side of the snap-in plate 304, so that the upper cone block 301 quickly hits the side of the lower cone block 307. During the collision, the kitchen waste between the upper cone block 301 and the lower cone block 307 can be squeezed, so that the air in the gap between the garbage is discharged, thereby reducing the inhibition of air on anaerobic fermentation in the fermentation tank 101.

[0033] See also Figure 4 In a preferred embodiment of the present invention, the driving mechanism 4 also includes a side bracket 405, a driving gear 406, a driven wheel 407, a synchronous belt 408 and a linkage rod 409, one end of the side bracket 405 is fixedly connected to the driving column 403, and the other end of the side bracket 405 is rotatably provided with two groups of driven wheels 407, and a synchronous belt 408 is installed between the two groups of driven wheels 407, the driving gear 406 is coaxially fixedly connected to one group of driven wheels 407, one end of the linkage rod 409 is connected to the synchronous belt 408, and the other end of the linkage rod 409 is fixedly connected to the lifting cylinder 404.

[0034] In actual application of this embodiment, when the driving column 403 rotates around the axis, the side bracket 405 at one end thereof rotates along with the driving column 403, and the two groups of driven wheels 407 arranged on the side bracket 405 are connected to each other through a synchronous belt 408. The driving gear 406 is coaxially fixedly connected to one group of driven wheels 407. The rotation of the driving gear 406 can synchronously drive the rotation of the driven wheels 407 and the synchronous belt 408. During the movement, the synchronous belt 408 can pull the linkage rod 409 to reciprocate in the vertical direction, so that the lifting cylinder 404 fixedly connected to the end of the linkage rod 409 can synchronously reciprocate in the vertical direction.

[0035] See also Figure 4 In a preferred embodiment of the present invention, the fermentation tank assembly 1 also includes an inverted ring rack 107 and an upright ring rack 108, and a plurality of the inverted ring racks 107 and the upright ring racks 108 are circumferentially arranged on the inner wall of the fermentation tank 101, and the inverted ring racks 107 and the upright ring racks 108 are arranged in sequence at intervals, and the inverted ring racks 107 and the upright ring racks 108 are both meshed and connected with the driving gear 406.

[0036] In actual application of this embodiment, the inverted ring rack 107 and the upright ring rack 108 are arranged in sequence at intervals, so that when the driving gear 406 follows the rotation of the driving column 403, it meshes with the inverted ring rack 107 and the upright ring rack 108 in sequence, so that the rotation direction of the driving gear 406 changes continuously. At the same time, the rotation direction of the synchronous belt 408 changes at the same time, so that the connecting rod 409 and the lifting cylinder 404 reciprocate in the vertical direction.
