[0034] 1. The whole device uses the linkage component as the core, and realizes the linkage control of the surface mixing component, the lifting component and the bottom mixing component by using different transformations of the linkage component. It can select different fertilizer turning effects according to the composting time of livestock manure. Compared with the traditional composting that requires manual turning or direct stirring, it is more efficient, has better effects, and has stronger fertilizer integration.

[0035] 2.

This allows livestock manure to become higher-quality compost and achieve higher economic results.

[0036] 3. When there is a lot of liquid in the manure, the device can lift the livestock manure and discharge the waste liquid into the waste liquid pool, greatly reducing the humidity of the manure in the composting box and improving the composting environment.

[0037] 4. The device can select different working modes according to needs, such as mixing only the surface layer, mixing the whole or lifting feces to discharge waste liquid to meet different composting needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] Example 3

[0072] Reference Figure 1-10 , a livestock manure composting method, the method comprising the following steps:

[0073] S1. Collect fresh livestock manure and crush corn stalks into 2mm-5mm particles;

[0074] S1a, feed the livestock manure into the compost bin 1 from the feeding port 11 until it overflows the detection end of one set of temperature and humidity sensors 4, and composts and ferments on its own for one day, and respectively measures the temperature and humidity in the livestock manure and the temperature and humidity in the compost bin 1 through the two sets of temperature and humidity sensors 4;

[0075] S1b, add gypsum and superphosphate, and then compost and ferment for three days, and measure the temperature and humidity in the livestock manure and the temperature and humidity in the compost box 1 respectively through two sets of temperature and humidity sensors 4;

[0076] S1c, adding white rot fungi, Bacillus, and gold probiotic fermentation agents, fermenting for one day, and measuring the temperature and humidity in the livestock manure and the temperature and humidity in the compost box 1 through two sets of temperature and humidity sensors 4;

[0077] S1d, adding crushed corn stalks and bran of equal mass, and measuring the temperature and humidity in the livestock manure and the temperature and humidity in the compost bin 1 by two sets of temperature and humidity sensors 4, and then the preparation process is completed;

[0078] S2, rotating the handle 21 to make the entire linkage assembly 2 rise, at which time the fifth gear 61 is disengaged from the first gear 24, the lifting assembly 6 does not work, and the second gears 25 of the middle and lower layers replace the second gears 25 of the upper and middle layers to mesh with the driving group 3, the surface mixing assembly 5 and the bottom mixing assembly 7;

[0079] S2a, start the servo motor 31 to drive the linkage component 2 to rotate, and start the surface mixing component 5 and the bottom mixing component 7 through the linkage component 2. The surface mixing component 5 mixes the crushed corn stalks and bran of equal mass on the surface of the livestock manure into the livestock manure. Then, the bottom mixing component 7 turns the bottom of the livestock manure to the surface, and then mixes it with the crushed corn stalks and bran of equal mass. The bottom mixing component 7 moves back and forth to mix. Whenever the sliding rack 71 touches the electric control button 16 on one side, the servo motor 31 will be controlled to rotate in the opposite direction.

[0080] S2b, mix two to three times a day, each time for 30 to 60 minutes, and ferment for three days;

[0081] S3, reversely rotate the handle 21 to reset the linkage assembly 2 and then start the servo motor 31. At this time, not only the surface mixing assembly 5 and the bottom mixing assembly 7 work, but also the lifting plate 66 drives the entire livestock manure to be lifted. At this time, the block 67 releases the restriction on the connection between the compost box 1 and the waste liquid pool 13, and the liquid in the livestock manure flows into the waste liquid pool 13 through the compost box 1. Multiple up and down movements will also allow the bottom gas of the livestock manure to circulate;

[0082] S3a. Mix two to three times a day, each time for thirty to sixty minutes, and ferment for three days.

[0083] S4, turning the handle 21 to move the entire linkage assembly 2 upward to disengage the bottom mixing assembly 7 and the lifting assembly 6 from the second gear 25 and the first gear 24 respectively, and then starting the servo motor 31 to drive only the surface mixing assembly 5 to move through the linkage assembly 2, that is, to mix the surface of the livestock manure that is about to be fermented again to increase the contact area with the air;

[0084] S4a, mix two to three times a day, each time for 30 to 60 minutes, and ferment for 7 to 14 days;

[0085] S5. After fermentation is completed, the lock on the discharge door 14 is opened, and the discharge door 14 is rotated to open the side of the compost bin 1, and the fermented feces are discharged from the inside of the compost bin 1. The liquid in the waste liquid pool 13 can be discarded or added into the compost bin 1 from the feeding port 11 when the next batch of fertilizers is not moist enough.

[0086] Furthermore, a cooling or heating temperature regulator may be added to the outside of the compost bin 1 , with the output end extending into the compost bin 1 , and determining whether the temperature needs to be adjusted based on the detection results of the temperature and humidity sensor 4 .

[0087] Furthermore, the transmission wheel 52 and the rotating crawler belt 53 can be replaced with crawler-type transmission belts or other transmission belts, as long as they can allow the surface mixing frame 54 to run stably on the rotating crawler belt 53 during the operation of the transmission wheel 52.

[0088] Furthermore, the surface mixing frame 54 is in the shape of a triangular fork and is equipped with steel spikes, which can effectively mix, smooth and push the surface of livestock manure, and circulate on the rotating crawler 53, and the effect is better than that of a conventional stirring rod.

[0089] Furthermore, the bottom mixing roller 74 is in a conventional roller shape with steel bars added to the surface, which can effectively stir the bottom layer of livestock manure and allow the upper and lower layers of livestock manure to blend.

[0090] Furthermore, the measuring end of the temperature and humidity sensor 4 is arranged so as not to hinder the operation of other structures.

[0091] Furthermore, the electric control button 16 is used to control the servo motor 31, but the electric control buttons 16 on both sides are only for changing the rotation direction of the servo motor, and the operation mode of the hydraulic rod 17 is that after it is powered on, the electric control buttons 16 on both sides additionally control the start of the hydraulic rod, and touching the corresponding side of the electric control button 16 will make the output rod of the hydraulic rod 17 extend or retract, and the electric control button 16 and other electrical components can be selected from the existing electrical components on the market that can realize the corresponding functions of the present invention, and the connection between the electrical components is the existing technology, so it is not elaborated in detail.

[0092] Furthermore, the size, torque and power of the servo motor 31 can be selected as needed, and the materials of all parts can be selected according to actual application conditions.

[0093] Working principle of the present invention: In the present invention, first, livestock manure needs to be fermented for one day, three days, and one day in sequence. In this process, the required fermentation agent, corn stalks, and bran are added, and the specific proportions can be referred to the following table:

[0094] Start to slowly increase the temperature on the second day, and keep the target temperature at 60° from the sixth day.

[0095]

[0096]

[0097] According to the above table, the best time period for nitrogen retention is from the twelfth day to the twenty-second day, and it tends to be stable after the fifteenth day, which means that the compost fermentation is basically completed at this time.

[0098] After adjusting the ratio, the handle 21 is rotated to make the whole linkage assembly 2 rise. At this time, the fifth gear 61 is disengaged from the first gear 24 to make the lifting assembly 6 stop working, and the second gears 25 of the middle and lower layers replace the second gears 25 of the upper and middle layers to mesh with the driving group 3, the surface mixing assembly 5 and the bottom mixing assembly 7. In addition, during the rotation of the handle 21, the screw rod 22 is threadedly connected to the compost bin 1, so the rotation of the handle 21 will make the screw rod 22 drive the whole linkage assembly 2 to rise, and under the action of the support spring 23, the whole linkage assembly 2 can rise more stably without shaking, and when it stops, it can also apply a pressure to resist the screw rod 22 to reduce shaking, thereby increasing the stability of the structure;

[0099] The whole device can be divided into three situations:

[0100] First, the lifting assembly 6 is not allowed to work. The servo motor 31 drives the third gear 33 to rotate through the first rotating rod 32, and then the third gear 33 rotates through the adjacent second gear 25, that is, the above-mentioned rotating handle 21 is a way for the entire linkage assembly 2 to rise once. In this way, the rotation of the second gear 25 will drive the fourth gear 51 to rotate. While the fourth gear 51 drives the adjacent transmission wheel 52 to rotate, the other transmission wheel 52 is driven, so that the multiple surface mixing frames 54 under the rotating crawler 53 stir the surface of livestock manure. When the second gear 25 drives the sliding rack 71 to move in the limiting slide groove 15, it will drive the first connecting rod 72 and the second connecting rod 73 to move through the sliding rack 71, and then drive multiple bottom mixing rollers 74 supported by the transverse support rod 75 to stir in the manure. In this case, the entire manure can be mixed to the maximum extent, achieving the most efficient mixing effect.

[0101] Second, the bottom mixing component 7 and the lifting component 6 are not allowed to work, and the handle 21 continues to be rotated upward. At this time, the servo motor 31 is started to drive only the surface mixing component 5 to move through the linkage component 2, that is, the surface of the livestock manure that is about to be fermented is mixed again to increase the contact area with the air. It is generally used when the overall fermentation is about to be completed.

[0102] Third, all work, that is, the initial position of the entire device, at this time, after the lifting plate 66 drives the entire livestock manure to be lifted, the block 67 releases the restriction on the connection between the compost box 1 and the waste liquid pool 13, and the liquid in the livestock manure flows into the waste liquid pool 13 through the compost box 1. Multiple up and down movements will also allow the bottom gas of the livestock manure to circulate, and in this process, the hydraulic rod 17 is energized, and the hydraulic rod 17 will start and stop as the sliding rack 71 touches the electric control buttons 16 on both sides, and the auxiliary lifting rack 65 lifts the entire lifting plate 66. During this process, the lifting plate 66 rises and will inevitably squeeze the multiple bottom mixing rollers 74 upwards. At this time, the second connecting rod 73 will compress the internal return spring and drive the bottom mixing rollers 74 to always be above the lifting plate 66, ensuring the overall operation is stable without squeezing and deformation. The entire livestock manure compost can be fully mixed. When there is a lot of liquid in the manure, the livestock manure can be lifted and the waste liquid can be discharged from the compost box 1 into the waste liquid pool 13, greatly reducing the humidity of the manure in the compost box 1.

[0103] During the whole process, the operator can observe and operate the operation of all the equipment of the whole device by standing on the pedal 12. After each treatment is completed, the surface of the lifting plate 66 is cleaned with a vacuum cleaner or a high-pressure water gun;

[0104] After completing the above operations, open the discharge door 14 for cleaning. The discharge door 14 is rotatably connected to the compost bin 1, and a lock is installed on the side of the compost bin 1 to prevent the discharge door 14 from being opened when it is not needed. A sealing ring is provided at the connection between the discharge door 14 and the compost bin 1.
