Description

Technical Field

[0001] The invention relates to the technical field of fermentation devices, in particular to a fermentation device and a processing method for earthworm bio-organic fertilizer. Background Art

[0002] During the process of breeding earthworms, earthworms can digest organic matter such as garbage and straw, and mix them with soil to excrete earthworm castings. Earthworm castings are good decomposed organic fertilizers and are also soil with a granular structure, which can promote the growth and development of crops. The collected earthworm castings contain many harmful bacteria and various harmful insect eggs, so they cannot be used directly and need to be fermented.

[0003] There are many problems that may be encountered during the fermentation of earthworm manure. First, too high temperature may cause the death of beneficial microorganisms in the earthworm manure and affect the fermentation effect. Too low temperature may slow down the fermentation process or even stagnate. Secondly, too high humidity can easily lead to an anaerobic environment during the fermentation of earthworm manure, thereby producing odor and harmful gases. Too low humidity may affect the activity of microorganisms and reduce fermentation efficiency. Finally, if the raw materials contain too many impurities, harmful substances or organic matter that is not fully decomposed, it may affect the fermentation quality. If the oxygen supply is insufficient, it may lead to incomplete fermentation or produce bad odor.

[0043] In this embodiment, the feeding mechanism 5 includes a first gear 51 fixedly connected to the first rotating shaft 31, the outer side of the first gear 51 is rotatably connected to the chain 52, the inner side of the chain 52 is rotatably connected to the second gear 53, the lower end of the second gear 53 is fixedly connected to the third rotating shaft 54, the outer side of the third rotating shaft 54 ​​is rotatably connected to the storage box 55, the outer side of the third rotating shaft 54 ​​is fixedly connected to three groups of sweeping rods 56, one side of the storage box 55 is fixedly connected to a mounting plate 59, the other side of the storage box 55 is provided with a blocking groove 514, the inner side of the mounting plate 59 is slidably connected to a discharge pipe 516, the outer side of the discharge pipe 516 is fixedly connected to a pressing plate 515, the upper and lower ends of the pressing plate 515 are in the same height as a group of sweeping rods 56 close to the bottom among the three groups of sweeping rods 56, and a feeding hole 521 is provided on the outer side of the discharge pipe 516 near the blocking groove 514.

[0044] Specifically, the first rotating shaft 31 drives the first gear 51 to rotate, the first gear 51 drives the second gear 53 to rotate through the chain 52, and the second gear 53 rotates the sweeping rod 56 through the third rotating shaft 54. The sweeping rod 56 stirs the fermentation bacteria inside the storage box 55. When the sweeping rod 56 rotates, it will intermittently contact the pressure plate 515 to press, and the pressure plate 515 drives the discharge pipe 516 to slide, and the blocking groove 514 makes the feed hole 521 and the storage box 55 staggered to avoid waste caused by continuous discharge.

[0045] In this embodiment, the outer side of the discharge pipe 516 is slidably connected to the second sleeve 517, and the second sleeve 517 is fixedly connected to the inner side of the mounting plate 59.

Then the fourth gear 58 meshes with the outer gear ring 511, so that the fourth gear 58 rotates 360 degrees outside the outer gear ring 511 and drives the mounting plate 59 to rotate. The two sets of rollers 510 slide on the outside of the fixed ring 512 and are limited to avoid misalignment when the mounting plate 59 moves. When the rollers 510 rotate, the outer gear ring 511 can be cleaned by the rough brush 522 to avoid contamination by impurities.

[0049] In this embodiment, the water replenishing mechanism 14 includes a water tank 141 fixedly connected to the mounting tube 1, and two groups of water outlets are opened at the lower end of the water tank 141. A pressure rod 142 is slidably connected to the inner side of the water tank 141, and the upper end of the pressure rod 142 is fixedly connected to a limiting block 143, and a clamping plate 144 is slidably connected to the outer side of the pressure rod 142.

After purification by the activated carbon adsorption box 61, the exhaust fan 64 is started to allow the air flow to be output to the outside through the exhaust pipe 65, so that the air inside the fermentation barrel 4 can be circulated to avoid excessive humidity, and oxygen is added in a cycle to maintain the activity of microorganisms. Depending on the climate, if the humidity is too high, the electric heating plate 9 can be started to heat the internal air, and then the air distribution mechanism 6 is used to circulate the air to reduce the humidity.

[0053] In this embodiment, a blade 15 is rotatably connected to the upper part of the inner exhaust pipe 65 of the installation tube 1 via a rotating shaft, and a spray head 16 is installed above the inner blade 15 of the installation tube 1 .

[0054] Specifically, when the humidity in the fermentation barrel 4 is too low, the spray head 16 is started to output clean water, and the exhaust pipe 65 outputs gas to blow the blades 15. The blades 15 rotate to break up the water sprayed from the spray head 16 to form water splashes, which are evenly scattered above the second collecting barrel 8, so as to moisten the organic fertilizer to a certain extent, improve the fermentation efficiency, and avoid low humidity caused by air circulation.

[0057] S2, the motor 13 is started to drive the first gear 51, and the first gear 51 drives the second gear 53 through the chain 52, so that the sweeping rod 56 stirs the storage box 55, and the sweeping rod 56 presses the pressing plate 515 when rotating, so that the discharge pipe 516 moves around the outer side of the outer gear ring 511 to output the fermentation bacteria in the storage box 55, and the fermentation bacteria are mixed with the organic fertilizer by moving on the outer gear ring 511, so as to assist the fermentation of the organic fertilizer;

[0058] S3, the first sleeve 37 drives the slider 39 to slide in the slide groove 310, so that the second rotating shaft 38 drives the second collecting barrel 8 to rotate and slide up and down by utilizing the height difference, so that the organic fertilizer in the second collecting barrel 8 is turned over, increasing the contact area between oxygen and organic fertilizer, so as to promote oxygen supply and microbial activity.

[0059] Working principle: when in use, open the cover plate 2 and put the organic fertilizer into the installation cylinder 1, and then concentrate it in the first collecting cylinder 7, start the motor 13, the motor 13 drives the first rotating shaft 31 to rotate, the first rotating shaft 31 drives the cross rod 32 to rotate, so that the roller 33 rolls and mixes the organic fertilizer inside the first collecting cylinder 7, and breaks some impurity particles, the first rotating shaft 31 drives the first gear 51 to rotate, the first gear 51 drives the second gear 53 to rotate through the chain 52, the second gear 53 rotates the sweeping rod 56 through the third rotating shaft 54, the sweeping rod 56 stirs the fermentation bacteria inside the storage box 55, and the sweeping rod 56 intermittently contacts the pressure plate 515 to press when rotating, so that the discharge pipe 516 slides into the second sleeve 517 and compresses the first spring 520, and then makes the feed hole 521 leave the blocking groove 514 and enter. In the storage box 55, the fermented bacteria liquid enters the discharge pipe 516 through the feed hole 521, and then is output to the hose 518, and then flows into the first collecting barrel 7 to mix with the organic fertilizer. The fixed rod 519 limits the position of the hose 518 to prevent the hose 518 from being pushed by the discharge pipe 516 and deflected. When the third rotating shaft 54 ​​rotates, it will also drive the third gear 57 to rotate. The third gear 57 meshes and drives the fourth gear 58 to rotate. Then the fourth gear 58 meshes with the outer gear ring 511, so that the fourth gear 58 rotates 360 degrees outside the outer gear ring 511 and drives the mounting plate 59 to rotate. The two sets of rollers 510 slide on the outside of the fixed ring 512 and are limited to avoid misalignment when the mounting plate 59 moves. When the rollers 510 rotate, the outer gear ring 511 can be cleaned by the fur brush 522 to avoid contamination by impurities.

[0060] When the chain 52 rotates, it will revolve through the movement of the mounting plate 59. When the chain 52 revolves, it will touch the arc-shaped pressing block 147. The arc-shaped pressing block 147 slides upward through its own arc surface design, and drives the pressure rod 142 to slide upward, and then compresses the second spring 145. The pressure rod 142 then drives the L-shaped clamping column 146 to move upward, and the maximum height is limited by the clamping plate 144. After the clamping plate 144 and the L-shaped clamping column 146 are staggered, the water outlet of the water tank 141 discharges water downward to moisten the organic fertilizer. After the chain 52 and the arc-shaped pressing block 147 are staggered, the second spring 145 is opened, the pressure rod 142 is reset, and the limit block 143 limits the position of the limit block 143 to avoid the misalignment of the pressure rod 142. After the material in the first aggregate barrel 7 is processed, the first aggregate barrel 7 can also be The cylinder 7 is cleaned, and the remaining organic fertilizer all enters the second collecting cylinder 8 for fermentation. Under the rolling, stirring and squeezing of the cross rod 32, the organic fertilizer is squeezed out of the first filter hole 11 and then falls into the second collecting cylinder 8 to form particles. When the first rotating shaft 31 rotates, it will also drive the L-shaped sweeping plate 34 to rotate, so that the upper end of the L-shaped sweeping plate 34 cleans the lower end of the first collecting cylinder 7 and cuts off the organic fertilizer, so that the fertilizer can form solid particles of uniform size, which is convenient for fermentation. The electric heating plate 9 can also be cleaned to prevent the electric heating plate 9 from being blocked by stains. The cross rod 32 then drives the temperature probe 35 and the humidity probe 36 to rotate inside the fermentation barrel 4 to uniformly detect the internal environment. When the first rotating shaft 31 rotates, it drives the first sleeve 37 to rotate, and the first sleeve 37 drives the sliding The block 39 slides in the slide groove 310, and when the second rotating shaft 38 is driven to rotate, the height difference of the slide groove 310 is used to realize the up and down movement of the second rotating shaft 38. When the second rotating shaft 38 drives the second collecting barrel 8 to rotate, it can also move up and down, so that the organic fertilizer in the second collecting barrel 8 is fully turned over, and the contact area between oxygen and fermented materials is increased. When the organic fertilizer is fermented in the second collecting barrel 8, the earthworm organic fertilizer will generate a temperature rise phenomenon during fermentation, and the hot air flow passes through the first filter hole 11 and accumulates upward. The exhaust fan 62 is started to make the exhaust pipe 63 take away the high-temperature gas inside the fermentation barrel 4. After purification by the activated carbon adsorption box 61, the exhaust fan 64 is started to make the air flow pass through the exhaust pipe 65 to be output to the bottom of the first collecting barrel 7, so that the air inside the fermentation barrel 4 is circulated Circulation can avoid excessive humidity, and oxygen is added in a cycle to maintain the activity of microorganisms. According to the climate, if the humidity is too high, the electric heating plate 9 can be started to heat the internal air, and then the air distribution mechanism 6 can be used for air circulation to reduce the humidity. When the humidity in the fermentation barrel 4 is too low, the spray head 16 is started to output clean water, and the exhaust pipe 65 outputs gas to blow the blades 15. The blades 15 rotate to break up the water source sprayed by the spray head 16 to form water splashes, which are evenly scattered above the second collecting barrel 8 to moisten the organic fertilizer to a certain extent, improve the fermentation efficiency, and avoid low humidity caused by air circulation. The blades 15 and the spray head 16 cooperate with the air distribution mechanism 6 to keep a balanced environment inside the fermentation barrel 4. When the organic fertilizer is fermented, water can be controlled through the second filter hole 12.To prevent the organic fertilizer from being too wet, the controlled water is discharged through the drain valve 10, and the fermented organic fertilizer is taken out through the material taking port 17.
