Description

Technical Field

[0001] The present invention relates to the technical field of feed fermentation, and particularly relates to a fermentation device for organic feed production. Background Art

[0002] Organic feed is a feed product processed and produced by an organic production system using organic feed raw materials in accordance with relevant organic feed standards. During the preparation of organic feed, the raw materials often need to be pulverized and then subjected to aerobic fermentation. The existing composting process is usually static composting, which often turns into anaerobic fermentation due to insufficient oxygen supply, producing a large amount of odors such as hydrogen sulfide and having an explosion risk. Therefore, in the prior art, corresponding turning equipment is used to turn the feed raw materials to achieve dynamic composting.

[0003] After retrieval, a patent with the Chinese patent application number CN202123117978.0 discloses a new type of organic feed fermentation chamber, including a housing, a plot, a bottom plate, a feed inlet, a temperature sensor, and a humidity sensor. The bottom end of the housing is symmetrically and fixedly installed with plots, and the bottom end of the plots is fixedly installed with a bottom plate. However, since the above technical solution does not provide a corresponding mechanism capable of effectively turning and stirring the pulverized raw materials, there is still a problem of low efficiency in feed fermentation processing. Summary of the Invention

A group of L-shaped support plates are fixedly installed on the outer wall of the top of the fermentation box. A cylinder is fixedly installed on the outer wall of the L-shaped support plates. The output shaft of the cylinder is fixedly installed with a mounting plate. A transmission switching mechanism is arranged on the outer wall of the top of the mounting plate. A pulverizing box is fixedly installed on the outer wall of the top of the fermentation box. A first pulverizing roller and a second pulverizing roller are rotatably connected to the inner walls on both sides of the pulverizing box. Short shafts and long shafts are respectively fixedly installed at both ends of the first pulverizing roller and the second pulverizing roller. The length of the long shaft is greater than the length of the short shaft. A first rotating shaft is rotatably connected to the inner walls on both sides of the fermentation box. A group of support frames are fixedly installed on the outer wall of the top of the bracket. A first rack plate is arranged on the outer wall of the top of the support frame. Both ends of the first rotating shaft are meshed and connected to the first rack plate through gears.

[0007] Preferably: A support plate is fixedly installed on the outer wall of the top of the bracket. A second electric push rod is fixedly installed on the outer wall of one side of the support plate. The output shaft of the second electric push rod is fixed to the outer wall of one side of the fermentation box.

[0008] Furthermore: A control panel is fixed to the outer wall of one side of the support plate, and the second electric push rod is electrically connected to the control panel.

[0009] Further preferably: A feed inlet is provided on the outer wall of the top of the fermentation tank, and a discharge pipe is provided on the outer wall of the top of the crushing tank.

[0010] As a preferred embodiment of the present invention: A sealing cover is connected to the outer wall of the top of the crushing tank by a hinge. A plurality of fixing rings are fixed to the outer wall of the first rotating shaft, a plurality of stirring rods are fixed to the outer wall of the fixing rings, and turning plates are fixed to the outer wall of the stirring rods.

[0011] As a further preferred embodiment of the present invention: A group of baffles are fixed to the outer wall of the top of the bracket. An airbag is fixed to the outer wall of one side of the baffle, the outer wall of one side of the airbag is fixed to the outer wall of one side of the fermentation tank, and the airbag is connected to the cylinder through an air duct.

[0012] As a further scheme of the present invention: The transmission switching mechanism includes a first electric push rod, a movable plate, a second rack plate, a third rack plate and a connecting plate. The first electric push rod is fixed to the outer wall of the top of the mounting plate. The movable plate is slidably connected to the outer wall of the top of the mounting plate. The output shaft of the first electric push rod is fixed to the outer wall of one side of the movable plate. The second rack plate and the third rack plate are respectively fixed to the outer wall of the top of the movable plate. The connecting plate is fixed to the outer walls of the second rack plate and the third rack plate. The short shaft is meshed and connected to the second rack plate through a gear.

[0013] On the basis of the foregoing scheme: A second touch switch is provided on the outer wall of the L-shaped support plate, and a group of first touch switches are provided on the outer wall of the top of the fermentation tank. The first touch switch, the first electric push rod and the second touch switch are respectively electrically connected to the control panel.

[0014] Preferably on the basis of the foregoing scheme: A group of guide plates are fixed to the inner wall of the crushing tank.

[0015] The beneficial effects of the present invention are:

[0016] 1. The transmission switching mechanism on the outer wall of the mounting plate drives the long shafts at one ends of the first crushing roller and the second crushing roller to rotate relatively, driving the first crushing roller and the second crushing roller to rotate relatively, continuously crushing the raw materials inside the crushing tank. When the fermentation tank moves back and forth, the first rotating shaft will continuously rotate back and forth under the meshing connection of the gear and the first rack plate, driving the stirring rods and turning plates on the outer wall to continuously stir and turn the raw materials that have been crushed and entered the fermentation tank. While automatically crushing the raw materials, it can automatically stir and turn the crushed raw materials, improving the fermentation and processing efficiency of organic feed.

[0017] 2. When the air cylinder pushes the mounting plate downward to the top of the fermentation box, it will contact the first touch switch on the top of the fermentation box. At this time, the control panel will control the first electric push rod to drive the movable plate to move backward by a corresponding distance, so that the second rack plate leaves the gear on the outer wall of the short shaft on one side of the second crushing roller. At the same time, the third rack plate moves to one side of the gear on the outer wall of the long shaft on one side of the first crushing roller, disengaging the meshing connection between the second rack plate and the short shaft, and at the same time, making the third rack plate meshingly connected with the long shafts at one ends of the first crushing roller and the second crushing roller respectively. When the air cylinder drives the mounting plate to move upward, it can still drive the first crushing roller and the second crushing roller to rotate relatively through the meshing connection between the third rack plate and the long shaft, continuously crushing the raw materials inside the crushing box.

[0018] 3. When the air cylinder drives the mounting plate to rise to the maximum height, the connecting plate will contact the second touch switch on one side of the L-shaped support plate. At this time, the control panel will control the first electric push rod to push the movable plate forward and reset, so that the second rack plate meshes with the short shafts at one ends of the first crushing roller and the second crushing roller again, enabling the continuously moving up and down mounting plate to drive the first crushing roller and the second crushing roller to rotate relatively continuously through the second rack plate and the third rack plate on the outer wall.

[0019] 4. The material guiding plate can guide the raw materials poured into the crushing box, enabling the raw materials entering the crushing box to be better squeezed and crushed by the first crushing roller and the second crushing roller.

[0020] 5. When the fermentation box moves forward, it will squeeze the air bag on one side. After being pressed, the air bag will fill the internal gas into the inner wall of the corresponding air cylinder, and the output shaft of the air cylinder will push the entire mounting plate downward. When the fermentation box moves backward under the pulling of the second electric push rod, the air bag will expand again under the pulling of the fermentation box, thereby pumping the gas inside the air cylinder back into the air bag. At this time, the air cylinder will drive the mounting plate to move upward through the output shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment 1:

[0031] A fermentation device for organic feed production, as Figure 1-6 shown, includes a support 1. A group of guide rods 2 are fixed on the outer wall of the top of the support 1. A fermentation tank 17 is slidably connected to the outer wall of the top of the guide rod 2. A sealing door is hinged to the outer wall of the bottom of the fermentation tank 17. A group of L-shaped support plates 10 are fixed on the outer wall of the top of the fermentation tank 17. A cylinder 9 is fixed on the outer wall of the L-shaped support plate 10. The output shaft of the cylinder 9 is fixed with a mounting plate 24. A transmission switching mechanism is arranged on the outer wall of the top of the mounting plate 24. A crushing box 15 is fixed on the outer wall of the top of the fermentation tank 17. A first crushing roller 25 and a second crushing roller 27 are rotatably connected to the inner walls on both sides of the crushing box 15. Short shafts 29 and a long shaft 28 are respectively fixed at both ends of the first crushing roller 25 and the second crushing roller 27. The length of the long shaft 28 is greater than the length of the short shaft 29. First rotating shafts 4 are rotatably connected to the inner walls on both sides of the fermentation tank 17. A group of support frames 3 are fixed on the outer wall of the top of the support 1. A first rack plate 5 is arranged on the outer wall of the top of the support frame 3. Both ends of the first rotating shaft 4 are meshed with the first rack plate 5 through gears;

[0032] A support plate 20 is fixed to the outer wall of the top of the bracket 1, and a second electric push rod 18 is fixed to the outer wall of one side of the support plate 20. The output shaft of the second electric push rod 18 is fixed to the outer wall of one side of the fermentation tank 17;

[0033] A control panel 19 is fixed to the outer wall of one side of the support plate 20, and the second electric push rod 18 is electrically connected to the control panel 19;

[0034] A feed inlet 7 is arranged on the outer wall of the top of the fermentation tank 17, and a discharge pipe 21 is arranged on the outer wall of the top of the crushing tank 15;

[0035] A sealing cover 14 is connected to the outer wall of the top of the crushing tank 15 by a hinge. A plurality of fixing rings 32 are fixed to the outer wall of the first rotating shaft 4, a plurality of stirring rods 30 are fixed to the outer wall of the fixing rings 32, and turning plates 31 are fixed to the outer wall of the stirring rods 30;

[0036] A group of baffle plates 22 are fixed to the outer wall of the top of the bracket 1, an air bag 23 is fixed to the outer wall of one side of the baffle plate 22, the outer wall of one side of the air bag 23 is fixed to the outer wall of one side of the fermentation tank 17, and the air bag 23 is connected to the cylinder 9 through a gas pipeline;

[0037] The staff first opens the sealing cover 14 on the top of the crushing tank 15, then puts the corresponding feed raw materials into the crushing tank 15, then closes the sealing cover 14, and then controls the second electric push rod 18 through the control panel 19 to push the fermentation tank 17 to move back and forth under the guidance of the guide rod 2. When the fermentation tank 17 moves forward, it will squeeze the air bag 23 on one side. After the air bag 23 is pressed, the internal gas will be filled into the inner wall of the corresponding cylinder 9, so as to push the whole mounting plate 24 to move downward through the output shaft of the cylinder 9. When the mounting plate 24 moves downward, it will drive the short shafts 29 at one ends of the first crushing roller 25 and the second crushing roller 27 on the inner wall of the crushing tank 15 to rotate relatively through the transmission switching mechanism on the outer wall, so as to drive the first crushing roller 25 and the second crushing roller 27 to rotate relatively, and roll and crush the raw materials entering the inside of the crushing tank 15. The crushed raw materials enter the inside of the fermentation tank 17 through the discharge pipe 21 and the feed inlet 7;

[0038] When the fermentation tank 17 moves backward under the pull of the second electric push rod 18, the air bag 23 will re-expand under the pull of the fermentation tank 17, so as to draw the gas inside the cylinder 9 back into the air bag 23. At this time, the cylinder 9 will drive the mounting plate 24 to move upward through the output shaft, so as to drive the long shafts 28 at one ends of the first crushing roller 25 and the second crushing roller 27 to rotate relatively through the transmission switching mechanism on the outer wall of the mounting plate 24, so as to drive the first crushing roller 25 and the second crushing roller 27 to continue to rotate relatively, and continuously crush the raw materials inside the crushing tank 15;

[0039] When the fermentation box 17 moves back and forth, the first rotating shaft 4 will continuously rotate back and forth under the meshing connection of the gear and the first rack plate 5, thereby driving the stirring rod 30 and the turning plate 31 on the outer wall to continuously stir and turn the raw materials that have entered the inside of the fermentation box 17 and been crushed. While automatically crushing the raw materials, it can automatically stir and turn the crushed raw materials, improving the fermentation and processing efficiency of the organic feed.

[0040] The control panel 19 will regularly control the second electric push rod 18 to push the fermentation box 17 back and forth correspondingly, thereby regularly stirring and turning the feed raw materials inside the fermentation box 17 through the stirring rod 30 and the turning plate 31, thereby further improving the fermentation and processing efficiency of the organic feed.

[0041] After the feed fermentation is completed, the staff can open the sealing door at the bottom of the fermentation box 17 to take out the fermented feed.

[0042] As Figure 1-4 shown, the transmission switching mechanism includes a first electric push rod 8, a movable plate 16, a second rack plate 11, a third rack plate 13 and a connecting plate 12. The first electric push rod 8 is fixed on the top outer wall of the mounting plate 24. The movable plate 16 is slidably connected to the top outer wall of the mounting plate 24. The output shaft of the first electric push rod 8 is fixed on one side outer wall of the movable plate 16. The second rack plate 11 and the third rack plate 13 are respectively fixed on the top outer wall of the movable plate 16. The connecting plate 12 is fixed on the outer walls of the second rack plate 11 and the third rack plate 13. The short shaft 29 is meshed and connected with the second rack plate 11 through a gear.

[0043] A second touch switch 33 is arranged on the outer wall of the L-shaped support plate 10, and a group of first touch switches 6 are arranged on the top outer wall of the fermentation box 17. The first touch switch 6, the first electric push rod 8 and the second touch switch 33 are respectively electrically connected to the control panel 19;

[0044] When the air cylinder 9 pushes the mounting plate 24 downward to the top of the fermentation box 17, it will contact the first touch switch 6 on the top of the fermentation box 17. At this time, the control panel 19 will control the first electric push rod 8 to drive the movable plate 16 to move backward by a corresponding distance, so that the second rack plate 11 leaves the gear on the outer wall of the short shaft 29 on one side of the second crushing roller 27, and at the same time moves the third rack plate 13 to one side of the gear on the long shaft 28 on one side of the first crushing roller 25. While releasing the meshing connection between the second rack plate 11 and the short shaft 29, the third rack plate 13 is respectively meshed and connected with the long shafts 28 at one ends of the first crushing roller 25 and the second crushing roller 27, so that when the air cylinder 9 drives the mounting plate 24 to move upward, it can still drive the first crushing roller 25 and the second crushing roller 27 to rotate relatively through the meshing connection between the third rack plate 13 and the long shaft 28, so as to continuously crush the raw materials inside.

[0045] When the air cylinder 9 drives the mounting plate 24 to rise to the maximum height, the connecting plate 12 will contact the second touch switch 33 on one side of the L-shaped support plate 10. At this time, the control panel 19 will control the first electric push rod 8 to push the movable plate 16 forward and reset, so that the second rack plate 11 will mesh with the short shafts 29 at one ends of the first crushing roller 25 and the second crushing roller 27 again. Thus, the continuously moving up and down mounting plate 24 can drive the first crushing roller 25 and the second crushing roller 27 to rotate continuously relative to each other through the second rack plate 11 and the third rack plate 13 on the outer wall, and crush the raw materials inside the crushing box 15.

[0046] At the same time, through the long shafts 28 and the short shafts 29 staggered at both ends of the first crushing roller 25 and the second crushing roller 27, when the second rack plates 11 on both sides of the first crushing roller 25 and the second crushing roller 27 mesh with the short shafts 29 on one side of the first crushing roller 25 and the second crushing roller 27 respectively, the second rack plates 11 and the short shafts 29 connected by meshing can prevent the first crushing roller 25 and the second crushing roller 27 from rotating as a whole when the first electric push rod 8 pushes the movable plate 16 to move backward. Thus, the third rack plate 13 can stably insert into one side of the gear on the outer wall of the long shaft 28 and mesh with the long shaft 28, avoiding the collision between the teeth of the third rack plate 13 and the gear on the outer wall of the long shaft 28 when the third rack plate 13 moves backward, and improving the stability of the fermentation device during operation.

[0047] When this embodiment is in use, the staff first opens the sealing cover 14 on the top of the crushing box 15, then puts the corresponding feed raw materials into the crushing box 15, then closes the sealing cover 14, and then controls the second electric push rod 18 through the control panel 19 to push the fermentation box 17 to move back and forth under the guidance of the guide rod 2. When the fermentation box 17 moves forward, it will squeeze the air bag 23 on one side. After being pressed, the air bag 23 will fill the internal gas into the inner wall of the corresponding air cylinder 9. Thus, the output shaft of the air cylinder 9 will push the whole mounting plate 24 to move downward. When the mounting plate 24 moves downward, it will drive the short shafts 29 at one ends of the first crushing roller 25 and the second crushing roller 27 on the inner wall of the crushing box 15 to rotate relatively through the transmission switching mechanism on the outer wall, thereby driving the first crushing roller 25 and the second crushing roller 27 to rotate relatively, and crushing and grinding the raw materials entering the inside of the crushing box 15. The crushed raw materials enter the inside of the fermentation box 17 through the discharge pipe 21 and the feed inlet 7;

[0048] When the fermentation box 17 moves backward under the pulling of the second electric push rod 18, the airbag 23 will re-inflate under the pulling of the fermentation box 17, so as to re-pump the gas inside the cylinder 9 into the airbag 23. At this time, the cylinder 9 will drive the mounting plate 24 to move upward through the output shaft, so as to drive the long shafts 28 at one ends of the first crushing roller 25 and the second crushing roller 27 to rotate relatively through the transmission switching mechanism on the outer wall of the mounting plate 24, so as to drive the first crushing roller 25 and the second crushing roller 27 to continue to rotate relatively, and continuously crush the raw materials inside the crushing box 15;

[0049] When the fermentation box 17 moves back and forth, the first rotating shaft 4 will continuously rotate back and forth under the meshing connection of the gear and the first rack plate 5, so as to drive the stirring rod 30 and the material turning plate 31 on the outer wall to continuously stir and turn the raw materials that enter the inside of the fermentation box 17 and are crushed. While automatically crushing the raw materials, it can automatically stir and turn the crushed raw materials.

[0050] After the feed fermentation is completed, the staff can open the sealing door at the bottom of the fermentation box 17 to take out the fermented feed.

The following improvements are made in this embodiment on the basis of Embodiment 1: As Figure 3 shown, a group of guide plates 26 are fixed on the inner wall of the crushing box 15; the guide plates 26 can guide the raw materials poured into the inside of the crushing box 15, so that the raw materials entering the inside of the crushing box 15 can be better squeezed and crushed by the first crushing roller 25 and the second crushing roller 27.

[0053] When this embodiment is in use, the guide plates 26 can guide the raw materials poured into the inside of the crushing box 15.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
