Description

Technical Field

[0001] The utility model relates to the technical field of microbial agent drip irrigation devices, in particular to a device for drip irrigation and application of microbial agents. Background Art

[0002] The salt contained in saline-alkali soil will affect the normal growth of crops. The formation of alkaline soil and alkaline soil in my country is mostly related to the accumulation of carbonates in the soil. Therefore, the alkalinity is generally high. Plants can hardly survive in severe saline-alkali soil areas. Therefore, in order to expand the planting area, it is urgent to improve the saline-alkali land to make it suitable for the cultivation of crops.

[0003] When improving saline-alkali land, carbon-based microorganisms can be used to improve the soil tillage structure, enhance the effective nutrients in the soil, and thus improve the production capacity of saline-alkali land. Microbial agents contain a large number of carbon-based microorganisms. Microbial agents refer to live bacterial preparations made by processing the fermentation liquid of target microorganisms (effective bacteria) after industrial production and expansion using porous substances as adsorbents (such as peat and vermiculite).

[0004] This kind of microbial agent is used for seed dressing or root dipping, and has the functions of directly or indirectly improving soil, restoring soil fertility, preventing soil-borne diseases, maintaining the balance of rhizosphere microbial flora and degrading toxic substances. The proper use of agricultural microbial agents can increase the yield of agricultural products, improve the quality of agricultural products, reduce the use of chemical fertilizers, reduce costs, improve soil, and protect the ecological environment.

[0005] Specifically, during application, the microbial agent mixture formed by mixing the microbial agent with water can be irrigated into saline-alkali land to enable the soil to retain water and reduce salt.

[0006] When the microbial agent mixture enters the soil of saline-alkali land, it can use the hydrophilic groups on the surface of the molecules in the microbial agent mixture to ionize and combine with water molecules to form hydrogen bonds, forming long chains with a large amount of charge, significantly increasing the number of soil aggregates, forming a good soil structure, and improving the soil's water retention and salt reduction capabilities.

[0007] After searching, a microbial agent drip irrigation device disclosed in announcement number CN206963347U includes: a water storage tank, a main pipe, and a dripper. The water storage tank is a water reservoir, the water storage tank is arranged at a high place, the main pipe is connected to the water storage tank, the main pipe is arranged above the roots of crops, there are multiple drippers, the drippers are evenly fixed under the main pipe, the drippers are composed of an inner pipe, an outer pipe, a filler, and a dripper, the inner pipe is connected and connected to the main pipe, the inner pipe is evenly provided with through holes, the outer pipe is sleeved on the inner pipe, the filler fills the inner pipe, and the dripper is connected to the outer pipe.

[0008] The microbial agent drip irrigation device disclosed in the patent document can drip the microbial agent into saline-alkali land, so that the saline-alkali land can retain water and reduce salt, thereby improving the fertility of the soil.

[0009] However, the water storage tank in the microbial agent drip irrigation device disclosed in the patent document cannot effectively mix the microbial agent with water, and the operating range of the drip irrigation is small. At the same time, it is also impossible to add nutrient solution at any time during the drip irrigation process.

[0010] Based on this, a device for drip irrigation to increase the application of microbial agents is proposed. Utility Model Content

[0045] Beneficial effects:

[0046] The utility model provides a device for drip irrigation to increase the application of microbial agents, which has the following beneficial effects:

[0047] 1. In the utility model, the stirring component can rotate in the inner cavity of the microbial agent mixing cylinder under the drive of the motor to mix and stir the microbial agent, and a plurality of groups of double-headed rotating mixing components installed on the stirring component also rotate accordingly. These double-headed rotating mixing components can stir the microbial agent at multiple angles and multiple levels to make the mixing more uniform;

[0048] The stirring component and the double-headed rotating mixing component can enable the microbial agent to be fully stirred in the microbial agent mixing barrel. This multi-component coordinated stirring method can break up the possible agglomeration of the agent, ensure the uniform dispersion of the agent particles, facilitate the subsequent full mixing with the nutrient solution, and enhance the activity of the microbial agent.

[0049] Second, in the utility model, the microbial agent can be mixed with the nutrient solution added from the nutrient solution filling branches at both ends of the main pipe side wall, and the two nutrient solution filling branches can add nutrient solution to the main pipe at any time;

[0050] A rubber plug can also be inserted into the nutrient solution filling branch head, and a number of air holes (not shown in the figure) are provided on the rubber plug. After the rubber plug is inserted into the corresponding nutrient solution filling branch head, the overflow of the bacterial agent can be avoided. At the same time, the several air holes on the rubber plug can facilitate the flow of the bacterial agent in the I-shaped pipeline structure.

[0051] 3. In the utility model, after the mixed liquid enters the main pipe, it will flow to the branch pipes connected to the side walls at both ends of the main pipe. Because the four branch pipes and the main pipe form an I-shaped structure, the liquid can be distributed more evenly to each branch pipe, and the operating range during drip irrigation is larger.

[0052] 4. In the utility model, a plurality of liquid outlet branches connected at the bottom of each branch pipeline guide the mixed liquid to the corresponding drip irrigation structure. The drip irrigation structure can evenly apply the mixed liquid to the saline-alkali land in a drip irrigation manner to conserve water and reduce salt in the saline-alkali land. At the same time, it can also restore the fertility of the soil in the saline-alkali land, thereby facilitating farming.

[0053] 5. In the utility model, the flow regulating valve is fastened and installed on the discharge port by bolts, which is convenient for repairing or replacing the flow regulating valve.

[0054] 6. In the present invention, the I-shaped pipeline structure can be detachably mounted on the flow regulating valve, so that the pipeline can be easily cleaned or replaced.

[0055] 7. In the utility model, each set of drip irrigation structures includes a filtering structure, and each filtering structure is detachably mounted on a corresponding liquid outlet branch. This detachable installation method is very convenient. On the one hand, it is easy to install and debug the device before use, ensuring that the filtering structure can be accurately connected to the liquid outlet branch and function normally. On the other hand, during long-term use, if the filtering structure is blocked or damaged, it can be easily and quickly disassembled for cleaning, repair or replacement without causing excessive interference to other parts of the entire device, thereby ensuring the maintainability and continuous operation capability of the device.

[0056] 8. In the present invention, a drip irrigation structure can be detachably mounted on each filter structure. This layered detachable mounting design makes the entire drip irrigation system more flexible and easy to maintain. The filter structure can be first mounted on the liquid outlet branch to ensure the realization of the filtering function, and then the drip irrigation structure can be mounted on the filter structure. When necessary, the drip irrigation structure or the filter structure can be operated separately, such as cleaning, replacement, etc.

[0057] 9. In the utility model, an upper drip irrigation channel is provided at the upper part of the inner cavity of each drip irrigation head, which has a relatively large inner diameter. The large inner diameter enables the filtered mixed liquid entering the drip irrigation head from the filler housing to flow into the upper drip irrigation channel more smoothly, providing a relatively spacious flow space for the mixed liquid at this stage, reducing the resistance of the liquid flow, and facilitating the mixed liquid to quickly enter the interior of the drip irrigation head for subsequent drip irrigation treatment;

[0058] The inner diameter of the lower drip irrigation channel at the lower part of the inner cavity of the drip irrigation head is smaller. This design is in contrast to the upper drip irrigation channel. By reducing the inner diameter, the flow of the mixed liquid is restricted to a certain extent, laying the foundation for the subsequent uniform and slow drip irrigation effect. The smaller inner diameter makes the flow rate of the mixed liquid relatively slow when it flows through the lower drip irrigation channel, which is more conducive to accurately dripping the mixed liquid out of the drip irrigation head in the form of drops;

[0059] The conical necking part located in the middle of the inner cavity of the drip irrigation head plays a key role in connecting the upper drip irrigation channel and the lower drip irrigation channel. Its top opening matches the inner diameter of the corresponding upper drip irrigation channel, and the bottom opening matches the inner diameter of the corresponding lower drip irrigation channel, forming a gradually shrinking channel structure. This conical structure can make the flow rate of the mixed liquid further reasonably adjusted in the process of flowing from the upper drip irrigation channel through the conical necking part into the lower drip irrigation channel;

[0060] Through the design of the inner diameter of each flow channel and the connection effect of the tapered necking part, precise control of the drip irrigation speed and dripping amount of the mixed liquid is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0072] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0073] Embodiment 1

[0074] like Figure 1-4 As shown, the utility model provides a technical solution:

[0075] A device for drip irrigation and microbial agent application, comprising:

[0076] A microbial agent mixing cylinder 10, wherein a feeding port 101 is provided on one side of the top of the microbial agent mixing cylinder 10, and a liquid discharge port 102 is provided at the center of the bottom of the microbial agent mixing cylinder 10;

[0077] The motor 20 is fixedly mounted at the top center of the microbial agent mixing cylinder 10, and the output shaft of the motor 20 passes through the top of the microbial agent mixing cylinder 10 downward and extends to the upper part of the inner cavity of the microbial agent mixing cylinder 10;

[0078] A stirring member 30, the stirring member 30 is installed in the inner cavity of the microbial agent mixing cylinder 10, and the top end of the stirring member 30 is connected to the output shaft of the motor 20;

[0079] The annular fixing frame 40 is fixedly mounted on the lower part of the inner cavity of the microbial agent mixing cylinder 10;

[0080] Wherein, the bottom end of the stirring member 30 is mounted on the annular fixing frame 40;

[0081] A plurality of groups of double-headed rotating mixing components 50, each of which is mounted on the stirring component 30;

[0082] A flow regulating valve 60, the flow regulating valve 60 is fastened and installed on the bottom end surface of the discharge port 102 by bolts;

[0083] An I-shaped pipeline structure 70, which is detachably mounted on the flow regulating valve 60;

[0084] The I-shaped pipeline structure 70 includes a main pipeline 701, and a liquid inlet branch 702 is connected to the middle of the side wall of the main pipeline 701, and the liquid inlet branch 702 is fastened to the flow regulating valve 60 by bolts;

[0085] Both ends of the side wall of the main pipe 701 are connected to nutrient solution filling branches 703;

[0086] Both sides of the side walls at both ends of the main pipeline 701 are connected with branch pipelines 704;

[0087] The four branch pipes 704 and the main pipe 701 are in an I-shape;

[0088] The bottom of each branch pipe 704 is connected to a plurality of liquid outlet branches 705; and

[0089] There are multiple groups of drip irrigation structures 80 , and each group of drip irrigation structures 80 is detachably mounted on a corresponding liquid outlet branch 705 .

[0090] In this embodiment, the microbial agent is added into the inner cavity of the microbial agent mixing cylinder 10 through the feeding port 101 on the top side of the microbial agent mixing cylinder 10. At this time, the agent is in a relatively static state. When the flow regulating valve 60 of the discharge port 102 at the bottom of the microbial agent mixing cylinder 10 is closed, the agent is stored in the mixing cylinder.

[0091] The motor 20 is turned on, and the output shaft of the motor 20 starts to rotate. Since the top of the stirring component 30 is connected to the output shaft of the motor 20, the stirring component 30 starts to rotate in the inner cavity of the microbial agent mixing barrel 10 under the drive of the motor 20 to mix and stir the microbial agent.

[0092] The plurality of groups of double-headed rotating mixing components 50 installed on the stirring component 30 also rotate accordingly. These double-headed rotating mixing components 50 can stir the microbial agent at multiple angles and multiple levels to make the mixture more uniform.

[0093] At the same time, the bottom end of the stirring member 30 is mounted on the annular fixing frame 40 , and the annular fixing frame 40 serves to stabilize the stirring member 30 , thereby ensuring the stability of the stirring process.

[0094] After the microbial agent is evenly mixed, the evenly mixed microbial agent is discharged from the discharge port 102 at the bottom center of the microbial agent mixing cylinder 10. A flow regulating valve 60 is installed on the bottom end surface of the discharge port 102 by bolt fastening, which can adjust the discharge flow of the microbial agent, thereby adjusting the mixing ratio of the agent and the nutrient solution.

[0095] The microbial inoculant enters the main pipeline 701 of the I-shaped pipeline structure 70 through the flow regulating valve 60 , and the liquid inlet branch 702 in the middle of the side wall of the main pipeline 701 is used to connect the flow regulating valve 60 and the main pipeline 701 .

[0096] In the main pipe 701 , the microbial agent can be mixed with the nutrient solution added from the nutrient solution filling branches 703 at both ends of the side wall of the main pipe 701 , and the two nutrient solution filling branches 703 can add nutrient solution to the main pipe 701 at any time.

[0097] After the mixed liquid enters the main pipeline 701, it will flow to the branch pipelines 704 connected to the side walls at both ends of the main pipeline 701. Because the four branch pipelines 704 and the main pipeline 701 are in an I-shaped structure, the liquid can be distributed more evenly to each branch pipeline 704, and the operating range during drip irrigation is larger.

[0098] The multiple liquid outlet branches 705 connected at the bottom of each branch pipe 704 guide the mixed liquid to the corresponding drip irrigation structure 80. The drip irrigation structure 80 can evenly apply the mixed liquid to the saline-alkali land in a drip irrigation manner to conserve water and reduce salt in the saline-alkali land. At the same time, it can also restore the fertility of the soil in the saline-alkali land, thereby facilitating farming.

[0099] The stirring component 30 and the double-headed rotating mixing component 50 can enable the microbial agent to be fully stirred in the microbial agent mixing barrel 10. This multi-component coordinated stirring method can break up the possible agglomeration of the agent, ensure that the agent particles are evenly dispersed, facilitate subsequent full mixing with the nutrient solution, and enhance the activity of the microbial agent.

[0100] The flow control valve 60 is fastened to the discharge port 102 by bolts, which is convenient for maintenance or replacement of the flow control valve;

[0101] The I-shaped pipeline structure 70 can be detachably mounted on the flow regulating valve 60, so as to facilitate cleaning or replacement of the pipeline.

[0102] More specifically, main pipeline blocking plates 7011 are fixedly installed at both ends of the main pipeline 701 , and branch pipeline blocking plates 7041 are fixedly installed at one outer end of each branch pipeline 704 .

[0103] In this embodiment, main line sealing plates 7011 are fixedly installed at both ends of the main line 701. The two sealing plates clearly define the boundaries of the main line 701 at both ends, structurally sealing the main line 701 and preventing the liquid in the main line 701 from leaking out from both ends.

[0104] A branch pipe sealing plate 7041 is fixedly installed on the outer end of each branch pipe 704. These sealing plates seal the outer end of the branch pipe 704, limiting the flow range of the liquid in the branch pipe 704, so that the liquid can only enter the branch pipe 704 from the connection between the branch pipe 704 and the main pipe 701, and then flow out from the liquid outlet branch 705 at the bottom of the branch pipe 704, and will not leak out from the outer end of the branch pipe 704.

[0105] Embodiment 2

[0106] like Figure 5 As shown, based on the first embodiment, the following improvements are made:

[0107] Furthermore, the stirring member 30 includes a stirring main shaft 301, a top end of the stirring main shaft 301 is fixedly connected to the output shaft end of the motor 20, and a bottom end of the stirring main shaft 301 is rotatably mounted in the inner ring of the annular fixing frame 40;

[0108] A plurality of stirring wing rods 302 are fixedly mounted on the side wall of the stirring main shaft 301, and the plurality of stirring wing rods 302 are distributed circumferentially on the stirring main shaft 301 from top to bottom;

[0109] Each set of double-headed rotating mixing elements 50 is mounted on a corresponding stirring wing rod 302 .

[0110] In this embodiment, the output shaft of the motor 20 can drive the rotation of the stirring shaft 301. The multiple stirring wing rods 302 fixedly installed on the side wall of the stirring shaft 301 will make circular motion together with the stirring shaft 301. The stirring wing rods 302 distributed in a circle on the stirring shaft 301 from top to bottom can continuously stir the microbial inoculum during the rotation process, so that the inoculum begins to be initially flipped and mixed in the inner cavity of the microbial inoculum mixing barrel 10.

[0111] For example, the bacterial agents originally accumulated at the bottom of the cylinder will be lifted up by the stirring wing rod 302, and the bacterial agents at different positions will collide and merge with each other, so that the bacterial agents will gradually become dispersed from a relatively static accumulation state.

[0112] Each set of double-headed rotating mixing components 50 is installed on the corresponding stirring wing rod 302. As the stirring wing rod 302 rotates, the double-headed rotating mixing component 50 will also make a circular motion around the stirring main shaft 301, and due to its own structural characteristics, it will further cut, disperse, mix, etc. the bacterial agent on the basis of the stirring of the stirring wing rod 302.

[0113] Each set of double-headed rotating mixing components 50 can penetrate into different flow layers generated by the stirring of the stirring wing rods 302, thereby solving the problem of uneven local mixing, making the mixing of the microbial inoculant more complete and detailed, and achieving better mixing uniformity.

[0114] The cooperation between the stirring wing rod 302 and the double-headed rotating mixing element 50 enables the mixing of the microbial inoculant to be more refined.

[0115] The stirring wing rod 302 is responsible for stirring and turning over a large area of ​​the microbial agent, while the double-headed rotating mixing component 50 processes the microbial agent more delicately. For example, it can better break up some tiny microbial agent aggregates so that each microbial agent particle can be evenly distributed in the mixing barrel, further improving the uniformity of the microbial agent mixing. In this way, the efficacy of the microbial agent can be more fully exerted when mixed with the nutrient solution, so that the soil in the saline-alkali land can be better absorbed and utilized.

[0116] Multiple stirring wing rods 302 are distributed circumferentially on the stirring main shaft 301, which increases the range of a single stirring action. Coupled with the synergistic effect of the double-headed rotating mixing component 50, within the same stirring time, the microbial agent can reach an ideal mixing state more quickly, shortening the time of the entire mixing process and improving the working efficiency of the device.

[0117] Embodiment 3

[0118] like Figure 5-6 as well as Fig. 9 As shown, based on the second embodiment, the following improvements are made:

[0119] Furthermore, each stirring wing rod 302 is provided with a mounting hole 3021, and each mounting hole 3021 penetrates vertically;

[0120] Each set of double-headed rotary mixing elements 50 includes a rotating shaft 501 . Each rotating shaft 501 is rotatably mounted in a corresponding mounting hole 3021 . An impeller 502 is fixedly mounted at both ends of each rotating shaft 501 .

[0121] In this embodiment, each stirring wing rod 302 is provided with a mounting hole 3021, and these mounting holes 3021 penetrate the stirring wing rod 302 from top to bottom. This up and down penetration design provides a convenient and specific connection channel for the subsequent installation of the double-headed rotating mixing component 50, making the installation structure relatively simple and stable.

[0122] The installation hole 3021 penetrating from top to bottom can ensure that when the rotating shaft 501 of the double-headed rotary mixing element 50 is installed, the rotating shaft 501 can rotate relatively smoothly in the hole.

[0123] Each set of double-headed rotating mixing components 50 includes a rotating shaft 501 and impellers 502 fixedly mounted at both ends of the rotating shaft 501. The rotating shaft 501 is rotatably mounted in the mounting hole 3021 of the corresponding stirring wing rod 302, which constitutes a connection relationship between the double-headed rotating mixing component 50 and the stirring wing rod 302, so that the double-headed rotating mixing component 50 can obtain initial rotational power as the stirring wing rod 302 rotates.

[0124] When the stirring main shaft 301 rotates under the drive of the motor 20, the stirring wing rod 302 rotates accordingly, thereby driving the rotating shaft 501 installed in its mounting hole 3021 to rotate, and the impellers 502 at both ends of the rotating shaft 501 will rotate at high speed with the rotation of the rotating shaft 501. The impellers 502 will have a strong stirring effect on the surrounding microbial inoculant during the rotation process. On the one hand, the inoculant is cut and pushed by the blade shape of the impeller 502 itself, so that the inoculant can flow and mix rapidly in a local range; on the other hand, since each double-headed rotating mixing component 50 has impellers 502 at both ends of the rotating shaft 501, this is equivalent to stirring the inoculant at multiple positions at the same time, further enhancing the mixing effect, and enabling the various components in the microbial inoculant to be more evenly dispersed in the microbial inoculant mixing barrel 10.

[0125] Embodiment 4

[0126] like Figure 1-2 As shown, based on the first embodiment, the following improvements are made:

[0127] Rubber plugs 90 are inserted and installed in the two nutrient solution filling branches 703 .

[0128] In this embodiment, a rubber plug 90 can also be inserted into the nutrient solution filling branch 703. The rubber plug 90 is also provided with a plurality of air holes (not shown in the figure). After the rubber plug 90 is inserted into the corresponding nutrient solution filling branch 703, the overflow of the bacterial agent can be avoided. At the same time, the plurality of air holes provided on the rubber plug 90 can facilitate the flow of the bacterial agent in the I-shaped pipeline structure 70.

[0129] Embodiment 5

[0130] like Figure 1 as well as Figure 8 As shown, based on the first embodiment, the following improvements are made:

[0131] Furthermore, each set of drip irrigation structures 80 includes a filtering structure, and each filtering structure can be detachably mounted on a corresponding liquid outlet branch 705;

[0132] A drip irrigation structure is also detachably mounted on each filtering structure.

[0133] In the present embodiment, each set of drip irrigation structures 80 includes a filtering structure, and each filtering structure is detachably mounted on the corresponding liquid outlet branch 705. This detachable installation method is very convenient. On the one hand, it is easy to install and debug the device before use, ensuring that the filtering structure can be accurately connected to the liquid outlet branch 705 and function normally. On the other hand, during long-term use, if the filtering structure is blocked or damaged, it can be easily and quickly removed for cleaning, repair or replacement without causing excessive interference to other parts of the entire device, thereby ensuring the maintainability and continuous operation capability of the device.

[0134] A drip irrigation structure can also be detachably mounted on each filter structure. This layered detachable mounting design makes the entire drip irrigation system more flexible and easy to maintain. The filter structure can be first mounted on the liquid outlet branch 705 to ensure the realization of the filtering function, and then the drip irrigation structure can be mounted on the filter structure. When necessary, the drip irrigation structure or the filter structure can be operated separately, such as cleaning, replacement, etc.

[0135] Furthermore, each filter structure includes a packing shell 801, each packing shell 801 is sleeved and installed on the corresponding liquid outlet branch 705, and a corrugated packing 802 is inserted and installed in the inner cavity of each packing shell 801;

[0136] Each drip irrigation structure is a drip irrigation head 803 , and each drip irrigation head 803 is plugged and installed in a corresponding filler housing 801 .

[0137] In this embodiment, each filler shell 801 is installed on the corresponding liquid outlet branch 705 by means of a socket-type installation. This socket-type installation has certain conveniences. It can connect the filler shell 801 to the liquid outlet branch 705 more firmly. At the same time, when it needs to be disassembled for maintenance or replacement, it is also relatively easy to operate. It only needs to be pulled out from the liquid outlet branch 705.

[0138] The corrugated packing 802 is installed by plugging in the inner cavity of the packing shell 801. This plug-in installation method allows the corrugated packing 802 to be stably placed in the packing shell 801 and will not easily shift during operation, thereby ensuring the stability of the filtering process.

[0139] The corrugated packing 802 has a special corrugated shape, which forms a complex filtering channel in the packing shell 801. When the mixed liquid enters the packing shell 801 from the liquid outlet branch 705 and flows through the corrugated packing 802, the impurities in the mixed liquid will be intercepted by the corrugated surface of the corrugated packing 802. Since the corrugated shape increases the contact area with the mixed liquid, the filtering effect is more significant, and impurities such as tiny particles and incompletely dissolved substances in the mixed liquid can be effectively removed.

[0140] Each drip irrigation head 803 is installed in the corresponding filler housing 801 by plugging. This installation method makes the drip irrigation head 803 closely connected with the filtering structure, which ensures the stability of the connection and facilitates separate disassembly and maintenance when necessary.

[0141] When the filtered mixed liquid enters the drip irrigation head 803, the drip irrigation head 803 will slowly drip out the mixed liquid in a uniform droplet form according to its own design structure.

[0142] Embodiment 6

[0143] like Figure 8 as well as Fig.10 As shown, it is improved on the basis of Example 5:

[0144] Furthermore, each filler shell 801 is interference fit with the corresponding liquid outlet branch 705 , and each drip irrigation head 803 is interference fit with the corresponding filler shell 801 .

[0145] In this embodiment, each packing shell 801 is connected to the corresponding liquid outlet branch 705 by means of interference fit. The interference fit means that the inner diameter of the packing shell 801 is slightly smaller than the outer diameter of the liquid outlet branch 705. During installation, a certain external force needs to be applied to put the packing shell 801 onto the liquid outlet branch 705 so that the two fit tightly together.

[0146] This interference fit provides a very reliable connection between the filler shell 801 and the liquid outlet branch 705. Once installed, the filler shell 801 will not easily fall off the liquid outlet branch 705 during normal operation, and can still maintain a stable connection even when the device is subject to a certain degree of external force interference such as vibration and shaking.

[0147] The interference fit also brings about good sealing performance. When the mixed liquid flows from the liquid outlet branch 705 into the packing shell 801, the two are closely fitted together, which can effectively prevent the mixed liquid from leaking out from their connection.

[0148] Each drip irrigation head 803 is connected to the corresponding filling shell 801 by interference fit. Similarly, this means that the outer diameter of the drip irrigation head 803 is slightly larger than the inner diameter of the filling shell 801. During installation, external force needs to be applied to insert the drip irrigation head 803 into the filling shell 801 so that it is tightly combined.

[0149] This interference fit establishes a firm connection between the drip irrigation head 803 and the filler housing 801. During long-term operation of the device, the drip irrigation head 803 will not easily fall out of the filler housing 801, and can maintain a stable connection even under frequent drip irrigation operations and possible external force impacts.

[0150] The interference fit also provides good sealing for the connection between the drip irrigation head 803 and the filler housing 801. When the filtered mixed liquid flows from the filler housing 801 into the drip irrigation head 803, the mixed liquid can be effectively prevented from leaking out from their connection.

[0151] Furthermore, each drip irrigation head 803 has an upper drip irrigation channel 8031 ​​at the upper part of the inner cavity, each drip irrigation head 803 has a lower drip irrigation channel 8032 at the lower part of the inner cavity, and each drip irrigation head 803 has a tapered necking portion 8033 at the middle part of the inner cavity;

[0152] Wherein, the inner diameter of each upper drip irrigation channel 8031 ​​is greater than the inner diameter of the lower drip irrigation channel 8032;

[0153] The top opening of each tapered necking portion 8033 matches the inner diameter of the corresponding upper drip irrigation channel 8031 ​​, and the bottom opening of each tapered necking portion 8033 matches the inner diameter of the corresponding lower drip irrigation channel 8032 .

[0154] In this embodiment, an upper drip irrigation channel 8031 ​​is provided on the upper part of the inner cavity of each drip irrigation head 803, which has a relatively large inner diameter. The large inner diameter allows the filtered mixed liquid entering the drip irrigation head 803 from the filler shell 801 to flow into the upper drip irrigation channel 8031 ​​more smoothly. At this stage, a relatively spacious flow space is provided for the mixed liquid, reducing the resistance to liquid flow, and facilitating the mixed liquid to quickly enter the interior of the drip irrigation head 803 for subsequent drip irrigation treatment.

[0155] In contrast, the lower drip irrigation channel 8032 at the lower part of the inner cavity of the drip irrigation head 803 has a smaller inner diameter. This design is in contrast to the upper drip irrigation channel 8031. By reducing the inner diameter, the flow of the mixed liquid is restricted to a certain extent, laying the foundation for the subsequent uniform and slow drip irrigation effect. The smaller inner diameter makes the flow rate of the mixed liquid relatively slow when it flows through the lower drip irrigation channel 8032, which is more conducive to accurately dripping the mixed liquid out of the drip irrigation head 803 in the form of drops.

[0156] The tapered necking portion 8033 located in the middle of the inner cavity of the drip irrigation head 803 plays a key role in connecting the upper drip irrigation channel 8031 ​​and the lower drip irrigation channel 8032. Its top opening matches the inner diameter of the corresponding upper drip irrigation channel 8031, and the bottom opening matches the inner diameter of the corresponding lower drip irrigation channel 8032, forming a gradually shrinking channel structure. This tapered structure can further reasonably adjust the flow rate of the mixed liquid in the process of flowing from the upper drip irrigation channel 8031 ​​through the tapered necking portion 8033 into the lower drip irrigation channel 8032.

[0157] On the one hand, it avoids the turbulence of liquid flow caused by the large difference in inner diameters of the upper drip irrigation channel 8031 ​​and the lower drip irrigation channel 8032; on the other hand, through the gradually shrinking flow channel, the mixed liquid has a more suitable flow rate and pressure when entering the lower drip irrigation channel 8032, which is more conducive to achieving a uniform, slow and precise drip irrigation effect.

[0158] The synergistic effect of the upper drip irrigation channel 8031, the tapered neck portion 8033 and the lower drip irrigation channel 8032 helps to achieve uniform drip irrigation. The mixed liquid flows quickly and smoothly into the upper drip irrigation channel 8031, and after the flow rate is adjusted by the transition of the tapered neck portion 8033, it enters the lower drip irrigation channel 8032 at a relatively slow and stable flow rate, and finally drips out of the drip irrigation head 803 from the lower drip irrigation channel 8032 in a uniform drop form.

[0159] By designing the inner diameter of each flow channel and the connection effect of the tapered necking portion 8033, precise control of the drip irrigation speed and dripping amount of the mixed liquid is achieved.

[0160] In summary, the workflow of the utility model is:

[0161] like Figure 1-10As shown, the microbial agent is added into the inner cavity of the mixing cylinder through the feeding port 101 on the top side of the microbial agent mixing cylinder 10. At this time, the agent is in a relatively static state. When the flow regulating valve 60 of the discharge port 102 at the bottom of the mixing cylinder is closed, the agent is stored in the mixing cylinder.

[0162] The motor 20 is turned on, and the output shaft of the motor 20 starts to rotate. Since the top of the stirring component 30 is connected to the output shaft of the motor 20, the stirring component 30 starts to rotate in the inner cavity of the microbial agent mixing barrel 10 under the drive of the motor 20 to mix and stir the microbial agent.

[0163] The plurality of groups of double-headed rotating mixing components 50 installed on the stirring component 30 also rotate accordingly. These double-headed rotating mixing components 50 can stir the microbial agent at multiple angles and multiple levels to make the mixture more uniform.

[0164] At the same time, the bottom end of the stirring member 30 is mounted on the annular fixing frame 40 , and the annular fixing frame 40 serves to stabilize the stirring member 30 , thereby ensuring the stability of the stirring process.

[0165] After the microbial agent is evenly mixed, the evenly mixed microbial agent is discharged from the discharge port 102 at the bottom center of the microbial agent mixing cylinder 10. A flow regulating valve 60 is installed on the bottom end surface of the discharge port 102 by bolt fastening, which can adjust the discharge flow of the microbial agent, thereby adjusting the mixing ratio of the agent and the nutrient solution.

[0166] The microbial inoculant enters the main pipeline 701 of the I-shaped pipeline structure 70 through the flow regulating valve 60 , and the liquid inlet branch 702 in the middle of the side wall of the main pipeline 701 is used to connect the flow regulating valve 60 and the main pipeline 701 .

[0167] In the main pipe 701 , the microbial agent can be mixed with the nutrient solution added from the nutrient solution filling branches 703 at both ends of the side wall of the main pipe 701 , and the two nutrient solution filling branches 703 can add nutrient solution to the main pipe 701 at any time.

[0168] Among them, a rubber plug 90 can also be inserted into the nutrient solution filling branch 703, and a plurality of air holes (not shown in the figure) are provided on the rubber plug 90. After the rubber plug 90 is inserted into the corresponding nutrient solution filling branch 703, the overflow of the bacterial agent can be avoided. At the same time, the plurality of air holes provided on the rubber plug 90 can facilitate the flow of the bacterial agent in the I-shaped pipeline structure 70.

[0169] After the mixed liquid enters the main pipeline 701, it will flow to the branch pipelines 704 connected to the side walls at both ends of the main pipeline 701. Because the four branch pipelines 704 and the main pipeline 701 are in an I-shaped structure, the liquid can be distributed more evenly to each branch pipeline 704, and the operating range during drip irrigation is larger.

[0170] The multiple liquid outlet branches 705 connected at the bottom of each branch pipe 704 guide the mixed liquid to the corresponding drip irrigation structure 80. The drip irrigation structure 80 can evenly apply the mixed liquid to the saline-alkali land in a drip irrigation manner to conserve water and reduce salt in the saline-alkali land. At the same time, it can also restore the fertility of the soil in the saline-alkali land, thereby facilitating farming.

[0171] The stirring component 30 and the double-headed rotating mixing component 50 can enable the microbial agent to be fully stirred in the microbial agent mixing barrel 10. This multi-component coordinated stirring method can break up the possible agglomeration of the agent, ensure that the agent particles are evenly dispersed, facilitate subsequent full mixing with the nutrient solution, and enhance the activity of the microbial agent.

[0172] The flow control valve 60 is fastened to the discharge port 102 by bolts, which is convenient for maintenance or replacement of the flow control valve;

[0173] The I-shaped pipeline structure 70 can be detachably mounted on the flow regulating valve 60, so as to facilitate cleaning or replacement of the pipeline.

[0174] The above different embodiments can be combined, replaced and used in conjunction with each other.

[0176] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
