[0015] As a preferred technical solution of the present application, the blade and the soil crushing shaft are detachably connected.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the scheme of the present application, a biogas fertilizer root fertilizing device with adjustable depth is provided, wherein the fertilizing structure is connected with a soil crushing shaft. When performing fertilizing operation, the punching structure is inserted into the soil, and the driving structure drives the soil crushing shaft to crush the soil clods. At the same time, the biogas fertilizer is discharged from the second feeding channel of the soil crushing shaft. During the growth of crops, nutrients are absorbed from the surrounding soil, so that the soil far away from the crops is more fertile, and the soil near the crops is relatively poor. The soil crushing shaft can transfer part of the fertile soil far away from the crops to the part near the crops, thereby improving the fertility of the soil around the crops. While the soil crushing shaft is crushing the soil, the soil and biogas fertilizer are further mixed, thereby increasing the contact area between the biogas fertilizer and the soil, and increasing the amount of biogas fertilizer absorbed by the soil. At the same time, the biogas fertilizer is discharged from the discharge port of the soil crushing shaft to a deeper part of the soil, and the soil above the discharge port covers the biogas fertilizer, thereby effectively reducing the volatilization of the biogas fertilizer, further increasing the biogas fertilizer absorption efficiency of the crops, and increasing the crop yield. When fertilizing, the soil crushing shaft is inserted deep into the soil. A blade is provided at the bottom of the soil crushing shaft, so that the soil crushing efficiency of the lower part is higher, the soil clods of the upper part are larger, and the soil clods of the lower part are smaller. The biogas fertilizer is discharged from the discharge port. The soil above the soil crushing shaft can cover the soil after fertilization, reducing the contact between fertilizer and air, effectively reducing the volatilization of biogas fertilizer, and reducing the procedure of covering soil after fertilization. When fertilizing some soil that needs to be turned over, the soil crushing shaft is inserted into the soil, and the soil just covers part of the soil crushing shaft. The biogas fertilizer is discharged from the discharge port to the deeper part of the soil. The lifting structure makes the soil crushing shaft rise or fall periodically. When the soil crushing shaft rises, part of the soil crushing shaft is away from the soil. At the same time, the soil crushing shaft rotates so that some soil blocks are turned over. The biogas fertilizer includes biogas liquid and biogas residue. The blade cuts the biogas residue at the same time when crushing the soil, so that the biogas fertilizer is mixed with the deeper soil more evenly. When the soil crushing shaft is inserted into the soil for fertilization, biogas fertilizer is discharged into the soil from the discharge port. The lifting structure makes the soil crushing shaft lower periodically to discharge biogas fertilizer to a deeper level in the soil. Some weed seeds are usually distributed on the soil surface. A deeper fertilization depth can reduce the nutrients absorbed by some weed seeds from fertilizers, effectively inhibit the growth of some weed seeds, reduce weed control costs, and reduce weed competition. Biogas fertilizer includes biogas liquid and biogas residue, which can provide a growth environment for some pests. A deeper fertilization depth reduces the exposure of fertilizers, reduces the risk of crop diseases and insect pests, and can also reduce the loss of biogas fertilizer caused by some organisms. By providing a lifting structure, when there are stones and / or relatively hard clods in the soil, the soil crushing shaft that periodically rises or lowers its height avoids the stones and / or relatively hard clods when crushing the soil, thereby reducing the wear of the soil crushing shaft caused by the stones and / or relatively hard clods, thereby reducing the risk of damage to the fertilization device and increasing the service life of the fertilization device.

[0017] 2. Furthermore, by providing a water tank, the fertilizing device can simultaneously supply water to the crops during fertilization. At the same time, the water in the water tank is discharged through the second feeding channel and mixed with the soil, which reduces the hardness of the soil and makes it easier for the soil crushing shaft to crush the soil blocks, thereby achieving the purpose of accelerating the mixing of soil, biogas fertilizer and water. When supplying water, the water in the soil is more likely to guide part of the biogas fertilizer to deeper into the soil, so that the water and biogas fertilizer are closer to the roots of the crops, which is convenient for the roots of the crops to absorb. After watering, the soil is more likely to mix and wrap the biogas fertilizer, thereby increasing the soil's absorption of biogas fertilizer, further increasing the biogas fertilizer absorption efficiency of crops, and increasing crop yields.

[0018] 3. Furthermore, by providing a confluence section, the biogas fertilizer in the first feeding channel and the water in the third feeding channel can be mixed after entering the confluence section, and then discharged into the soil through the second feeding channel. The mixed biogas fertilizer and water are easier for the soil to absorb. At the same time, the biogas fertilizer is easier to enter the deep soil through the gaps in the broken soil blocks through the guidance of water. The water and biogas fertilizer deep in the soil are easier to be absorbed by the roots of crops. The deeper fertilization depth reduces the exposure of fertilizers, reduces the risk of crop diseases and pests, and can reduce the loss of biogas fertilizer caused by some organisms.

[0019] 4. Furthermore, by providing a lifting structure, the cam drives the lifting platform to raise the lifting rod and the soil-crushing shaft. The lifting platform is connected to the fertilization structure through the first spring, so that when the distance between the cam and the lifting platform gradually increases, the lifting platform can automatically reset, so that the height of the lifting rod and the soil-crushing shaft decreases, so as to achieve the effect of periodic increase or decrease in the height of the soil-crushing shaft. The biogas fertilizer and water flow to the deep soil through the gaps of the soil blocks, so that the amount of biogas fertilizer and water in the soil gradually increases from top to bottom. Crops absorb nutrients through their roots, and the biogas fertilizer and water near the roots can be more easily absorbed by the roots of crops. At the same time, the biogas fertilizer and water in the upper part are partially absorbed by the soil, thereby improving the fertility of the soil. Since the soil-crushing shaft rotates around the fertilization structure to crush the soil.

[0020] 5. Furthermore, by providing a stirring structure, the biogas fertilizer and water entering the confluence section are mixed and then discharged through the fertilization structure. The mixed biogas fertilizer is partially dissolved in water. The biogas fertilizer dissolved in water can reduce the amount of volatilization in the air, making it easier to enter deep into the soil through the gaps after the soil is crushed, thereby improving the absorption efficiency of the biogas fertilizer by the roots of crops.

[0021] 6. Furthermore, by providing a seal, the elastic potential energy of the second spring is the smallest in the initial state of the seal, and the degree of closure of the third feed channel is the smallest. By rotating the output shaft, the distance between the seal and the output shaft is gradually reduced, so that the seal gradually closes the third feed channel, thereby adjusting the water output of the fertilizer and water device. When the soil block is relatively hard, the resistance of the soil crushing shaft is relatively large, and the speed is reduced, so that the soil crushing efficiency of the soil crushing shaft for the soil block is relatively low. When the seal is in the initial state, the water output of the fertilization device is relatively large, and the discharged water is used to reduce the hardness of the soil block; When the soil block is harder, the rotation speed of the fertilization device is lower, which reduces the frequency of the seal blocking the third feeding channel. At this time, the water output is larger, and the harder soil block absorbs water and reduces its hardness, making some soil blocks easier to chop. At the same time, the lifting structure raises or lowers the height of the soil crushing shaft to avoid some harder soil blocks and reduce the risk of damage to the soil crushing shaft. At the same time, the discharge port gradually discharges water to reduce the hardness of the soil block, so that the soil block is gradually chopped and the rotation speed of the fertilization device gradually increases. After the hardness of the soil block decreases, the resistance of the soil crushing shaft decreases, the rotation speed increases, the frequency of the seal blocking the third feeding channel increases, the water output decreases, and the water output is controlled.

[0022] 7. Furthermore, the insertion depth of the fertilizing device can be adjusted by adjusting the length of the telescopic rod, so that the fertilizing device is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

When performing fertilization operations, the perforated structure is inserted into the soil, and the soil crushing shaft 10 is driven by the rotating shaft 8 to crush the soil clods. At the same time, the biogas fertilizer is discharged from the second feeding channel 4 of the soil crushing shaft 10. During the growth of crops, nutrients from the surrounding soil are absorbed, so that the soil far away from the crops is more fertile, and the soil close to the crops is relatively poor. The soil crushing shaft 10 can transfer part of the fertile soil far away from the crops to the area close to the crops, thereby improving the fertility of the soil around the crops. While the soil crushing shaft 10 is crushing the soil, the soil and biogas fertilizer are further mixed, thereby increasing the contact area between the biogas fertilizer and the soil, and increasing the amount of biogas fertilizer absorbed by the soil. At the same time, the biogas fertilizer is discharged from the discharge port 19 of the soil crushing shaft 10 to a deeper part of the soil, and the soil above the discharge port 19 covers the biogas fertilizer, thereby effectively reducing the volatilization of the biogas fertilizer, thereby further increasing the biogas fertilizer absorption efficiency of the crops and increasing the crop yield. When fertilizing, the soil crushing shaft 10 is inserted deep into the soil. A blade 16 is provided at the bottom of the soil crushing shaft 10, so that the soil crushing efficiency of the lower part is higher, the soil clods of the upper part are larger, and the soil clods of the lower part are smaller. The soil above the soil crushing shaft can cover the soil after fertilization, reduce the contact between fertilizer and air, effectively reduce the volatilization of biogas fertilizer, and reduce the procedure of covering soil after fertilization. When fertilizing the soil that needs to be turned over, the soil crushing shaft 10 is inserted into the soil, and the soil just covers a part of the soil crushing shaft 10. The biogas fertilizer is discharged from the discharge port 19 to the deeper part of the soil. The lifting structure 11 causes the height of the soil crushing shaft 10 to rise or fall periodically. When the soil crushing shaft 10 rises, part of the soil crushing shaft 10 is away from the soil. At the same time, the soil crushing shaft 10 rotates so that part of the soil is turned up, and the biogas fertilizer is discharged from the discharge port 19. The biogas fertilizer includes biogas liquid and biogas residue. The blade 16 cuts the biogas residue while crushing the soil, so that the biogas fertilizer is mixed more evenly with the deeper soil. When the soil crushing shaft 10 is inserted into the soil for fertilization, the biogas fertilizer is discharged into the soil from the discharge port 19, and the lifting structure 11 causes the soil crushing shaft 10 to periodically lower its height to discharge the biogas fertilizer to a deeper level in the soil. Some weed seeds are usually distributed on the surface of the soil. A deeper fertilization depth can reduce the nutrients absorbed by some weed seeds from the fertilizer, effectively inhibit the growth of some weed seeds, reduce the cost of weed control, and reduce weed competition. Biogas fertilizer includes biogas liquid and biogas residue, which can provide a growth environment for some pests. A deeper fertilization depth reduces the exposure of fertilizers, reduces the risk of crop diseases and insect pests, and can also reduce the loss of biogas fertilizer caused by some organisms. By providing the lifting structure 11, when there are stones and / or relatively hard clods in the soil, the soil crushing shaft 10 which periodically rises or lowers its height avoids the stones and / or relatively hard clods when crushing the soil, thereby reducing the wear of the soil crushing shaft 10 caused by the stones and / or relatively hard clods, thereby reducing the risk of damage to the fertilization device and increasing the service life of the fertilization device.

[0029] As a preferred embodiment, on the basis of the above-mentioned manner, further, the body is further provided with a water tank 2, the body is provided with a third feed channel, the water tank 2 is connected to the third feed channel 5, the third feed channel 5 is connected to the second feed channel 4, and the water in the water tank 2 is discharged sequentially through the third feed channel 5 and the second feed channel 4; By providing a water tank 2, the fertilizing device can simultaneously supply water to the crops during fertilization. At the same time, the water in the water tank 2 is discharged through the second feeding channel 4 and mixed with the soil, which reduces the hardness of the soil and makes it easier for the soil crushing shaft 10 to crush the soil clods, thereby achieving the purpose of accelerating the mixing of soil, biogas fertilizer and water. When supplying water, the water in the soil is more likely to guide part of the biogas fertilizer to deeper into the soil, so that the water and biogas fertilizer are closer to the roots of the crops, which is convenient for the roots of the crops to absorb. After water supply, the soil is more likely to mix and wrap the biogas fertilizer, thereby increasing the soil's absorption of biogas fertilizer, further increasing the biogas fertilizer absorption efficiency of crops, and increasing crop yields.

[0030] As a preferred embodiment, on the basis of the above-mentioned manner, further, the third feed channel 5 is provided with a confluence section 6, and the confluence section 6 is located at the tail section of the third feed channel 5, and the confluence section 6 on the first feed channel 3 corresponding to the biogas fertilizer overlaps with the confluence section 6 of the third feed channel 5 corresponding to the water; By providing the confluence section 6, the biogas fertilizer in the first feeding channel 3 and the water in the third feeding channel 5 can be mixed after entering the confluence section 6, and then discharged into the soil through the second feeding channel 4. The mixed biogas fertilizer and water are easier for the soil to absorb. At the same time, the biogas fertilizer is easier to enter the deep soil through the gaps in the broken soil blocks through the guidance of water. The water and biogas fertilizer in the deep soil are easier to be absorbed by the roots of crops. The deeper fertilization depth reduces the exposure of fertilizers, reduces the risk of crop diseases and insect pests, and can reduce the loss of biogas fertilizer caused by some organisms.

[0031] As a preferred embodiment, on the basis of the above-mentioned manner, further, the rotating shaft 8 is connected with a cam 17, the fertilizing structure is provided with a lifting structure 11, the lifting structure 11 comprises a lifting rod 1102 and a lifting platform 1101, the lifting rod 1102 is connected with the soil crushing shaft 10, the lifting platform 1101 is connected with the punching structure through a first spring 14, and the cam 17 drives the lifting structure 11 to move after rotating; By gradually reducing the distance between the cam 17 and the lifting platform 1101, the lifting platform 1101 moves relative to the rotating shaft 8, compressing the first spring 14, and increasing the elastic potential energy of the first spring 14, so that the lifting rod 1102 is raised, thereby achieving the purpose of raising the height of the soil crushing shaft 10; By gradually increasing the distance between the cam 17 and the lifting platform 1101, the first spring 14 releases elastic potential energy to reset the lifting platform 1101 and the lifting rod 1102, thereby achieving the purpose of lowering the height of the soil crushing shaft 10; The soil crushing shaft 10 has a first state and a second state. The first state is when the elastic potential energy of the first spring 14 is the smallest, and the second state is when the elastic potential energy of the first spring 14 is the largest. When the soil crushing shaft 10 switches from the first state and the second state in sequence, the second feed channel 4 is connected to the merging section 6.

[0032] By providing a lifting structure 11, the cam 17 drives the lifting platform 1101 to raise the lifting rod 1102 and the soil crushing shaft 10, and the lifting platform 1101 is connected to the fertilization structure through the first spring 14, so that when the distance between the cam 17 and the lifting platform 1101 gradually increases, the lifting platform 1101 can automatically reset, so that the height of the lifting rod 1102 and the soil crushing shaft 10 decreases, so as to achieve the effect of periodic increase and decrease of the height of the soil crushing shaft 10, and the biogas fertilizer and water flow to the deep soil through the gaps of the soil blocks, so that the amount of biogas fertilizer and water in the soil gradually increases from top to bottom, and the crops absorb nutrients through the roots, and the biogas fertilizer and water near the roots can be more easily absorbed by the roots of the crops, and the biogas fertilizer and water in the upper part are partially absorbed by the soil, thereby improving the fertility of the soil. Since the soil crushing shaft 10 is rotated around the fertilization structure to crush the soil, when crushing the soil, the soil blocks in the upper part of the soil are larger, and the soil blocks in the lower part are smaller, so that air can enter the soil more easily, reducing the procedure of loosening the soil.

[0033] Embodiment 2: Based on the technical solution of embodiment 1, further, see Figure 1-Figure 5 As shown, the connecting and merging section 6 is provided with a stirring structure 9, and the stirring structure 9 includes an output shaft 901 and a plurality of blades 902, and the blades 902 are connected to the output shaft 901. After being driven by the motor 7, the output shaft 901 rotates around the rotating shaft 8, so that the blades 902 stir the biogas fertilizer and water; By providing a stirring structure 9, the biogas fertilizer and water entering the confluence section 6 are mixed and then discharged through the fertilization structure. The mixed biogas fertilizer is partially dissolved in water. The biogas fertilizer dissolved in water can reduce the amount of volatilization in the air, and is convenient for entering deep into the soil through the gaps after soil crushing, thereby improving the absorption efficiency of biogas fertilizer by the roots of crops. The deeper fertilization depth reduces the exposure of fertilizer, reduces the risk of crop diseases and insect pests, and can also reduce the loss of biogas fertilizer caused by some organisms.

[0034] As a preferred embodiment, on the basis of the above-mentioned manner, further, one end of the output shaft 901 is connected to the rotating shaft 8, and the other end is connected to the fixing member 12, the confluence section 6 is provided with a sealing member 13, and the sealing member 13 is used to block part of the third feeding channel 5, and one end of the sealing member 13 is connected to the fixing member 12, and the other end is connected to the fertilization structure through the second spring 18; The sealing member 13 has an initial state. When the sealing member 13 is in the initial state, the elastic potential energy of the second spring 18 is minimum. The fixing member 12 rotates around the output shaft 901, so that the distance between the sealing member 13 and the output shaft 901 is gradually reduced, so that the sealing member 13 gradually closes the third feeding channel 5, thereby adjusting the water output of the fertilizing device.

[0035] By providing the seal 13, the elastic potential energy of the second spring 18 is the smallest in the initial state of the seal 13, and the degree of closure of the third feed channel 5 is the smallest. By rotating the output shaft 901, the distance between the seal 13 and the output shaft 901 is gradually reduced, so that the seal 13 gradually closes the third feed channel 5, thereby adjusting the water output of the fertilizer and water device. When the soil block is relatively hard, the resistance of the soil crushing shaft 10 is relatively large, and the speed is reduced, so that the soil crushing efficiency of the soil crushing shaft 10 for crushing the soil block is relatively low. When the seal 13 is in the initial state, the water output of the fertilization device is relatively large, and the discharged water is used to reduce the hardness of the soil block. When the soil block is harder, the rotation speed of the fertilizer device is lower, so that the frequency of the seal 13 blocking the third feed channel 5 is lower. At this time, the water output is larger, and the harder soil block absorbs water and its hardness decreases, making some soil blocks easier to chop. At the same time, the lifting structure 11 raises or lowers the height of the soil crushing shaft 10 to avoid some harder soil blocks and reduce the risk of damage to the soil crushing shaft 10. At the same time, the discharge port 19 gradually discharges water to reduce the hardness of the soil block, so that the soil block is gradually chopped and the rotation speed of the fertilizer device gradually increases. After the hardness of the soil block decreases, the resistance of the soil crushing shaft 101 decreases, and the rotation speed increases, which increases the frequency of the seal 13 blocking the third feed channel 5, reduces the water output, and thus controls the water output.
