Description

Technical Field

[0001] The invention belongs to the technical field of soil fertility restoration, and in particular relates to a microbial cultivation device for restoring soil fertility. Background Art

[0002] Industrial wastewater, waste gas and waste residue contain heavy metals (such as mercury, cadmium, lead, etc.) and harmful substances. Once these pollutants enter the soil, they will damage the soil ecosystem. Heavy metals will accumulate in the soil, become toxic to soil microorganisms, and inhibit the growth and metabolic activities of microorganisms. At the same time, these pollutants will also affect the normal growth of plants, causing plants to absorb toxic substances, which will be transmitted through the food chain and endanger ecological safety. Add beneficial microbial agents to the soil, such as nitrogen-fixing bacteria, phosphate-solubilizing bacteria, potassium-solubilizing bacteria, etc. Nitrogen-fixing bacteria can convert nitrogen in the air into ammonia nitrogen that can be used by plants. Phosphate-solubilizing bacteria can decompose the fixed phosphorus in the soil and turn it into soluble phosphorus, which is convenient for plants to absorb. The prior art discloses some microbial culture and release devices that can continuously improve soil fertility. For example, CN215328022U discloses a microbial cultivation and release device for improving soil fertility. The release component disclosed in the device includes a first liquid outlet pipe, and the distal end of the first liquid outlet pipe extends toward the soil layer to release the microorganisms. However, in this type of device, since the first liquid outlet pipe is closer to the center of the culture medium and the distal end is too far away from the culture medium, the release of the microorganisms is uneven.

[0014] The present invention discloses a microbial cultivation device for repairing soil fertility. A culture medium can be stored in a release cylinder. Water is then sprayed in the culture medium to wash out some of the microorganisms in the culture medium and form a microbial suspension. The microbial suspension is transported to different positions of the soil layer through a horizontal release pipe to promote the diffusion of the microorganisms in the soil layer.

DETAILED DESCRIPTION

[0028] like Figures 1 to 9 As shown, a microbial cultivation device for repairing soil fertility disclosed in the present invention comprises a release tube 1 for releasing microorganisms, and a plurality of groups of release devices 2 uniformly distributed around the release tube 1 along the circumference. The release tube 1 is cylindrical as a whole, and the axis of the release tube 1 is along the vertical direction. The release device 2 of the present invention is divided into two groups, and the release device 2 is pre-buried in the soil layer 3; they are respectively located on the left and right sides of the release tube 1. Those skilled in the art can rotate different numbers of release devices 2 as needed to ensure that the soil fertility in an area is improved. In the embodiment of the present invention, the release device 2 is a layer, and the microorganisms in the upper layer can flow to the lower side. The release device 2 can also be set to multiple layers according to the thickness of the soil.

[0029] Specifically, the release device 2 includes a horizontal release tube 4, an elastic pressure pushing device, a sliding limit plate 5, an elastic support device and a ball 6. The horizontal release tube 4 is in a straight tube shape. The inner end of the horizontal release tube 4 is connected to the release tube 1. The outer end of the horizontal release tube 4 extends outward along the radial direction of the release tube 1. A plurality of horizontal release holes 7 are evenly spaced on the upper surface of the horizontal release tube 4. The microorganisms in the release tube 1 can enter the horizontal release tube 4 and then be released through the horizontal release holes 7 on the horizontal release tube 4, thereby increasing the fertility of the soil. The projection of the horizontal release hole 7 of the present invention on the horizontal plane is circular.

[0030] Among them, a ball 6 is installed in the horizontal release hole 7. In a normal state, the ball 6 just closes the horizontal release hole 7 to prevent the microorganisms from overflowing prematurely. The horizontal release hole 7 can also limit the ball 6 on its inner side to prevent the ball 6 from falling.

[0031] An elastic support device is installed on the inner side of the outer end of the horizontal release tube 4, and the elastic support device is connected to a sliding limit plate 5. A slide groove 8 is opened axially in the horizontal release tube 4, and the slide groove 8 passes through each horizontal release hole 7 in turn. The sliding limit plate 5 is slidably installed in the slide groove 8; a plurality of groups of hole areas 9 and filter areas 10 corresponding to the horizontal release holes 7 are arranged at intervals on the sliding limit plate 5.

[0032] The sliding seal of the elastic pressure pushing device of the present invention is arranged on the inner side of the horizontal release tube 4. When the pressure in the release tube 1 increases, the elastic pressure pushing device can be driven to move toward the elastic support device in the horizontal release tube 4. When the elastic pressure pushing device moves to contact with the elastic support device, it can drive the sliding limit plate 5 to move together. At this time, the edge of the hole area 9 on the sliding limit plate 5 acts on the ball 6, so that the ball 6 rolls into the filter area 10 on the sliding limit plate 5. At this time, the filter area 10 can overflow microorganisms normally. The multiple filter areas 10 on the sliding limit plate 5 can correspond to the release holes at the same time, thereby avoiding the release hole close to the opening 11 from overflowing microorganisms first, and ensuring the uniformity of microbial culture release.

[0033] In the device of the present invention, in a normal state, the hole area 9 corresponds to the horizontal release hole 7, and the ball 6 just closes the hole area 9 and the horizontal release hole 7, preventing impurities in the soil from entering the horizontal release hole 7, thereby reducing the risk of blockage. When the elastic pressure pushes the device to move to contact the elastic support device, the ball 6 can be opened by sliding the limit plate 5, so that the microorganisms can be released normally, the device is smooth to use, and the release stability of the microorganisms is better.

[0034] In this embodiment, the lower end of the release cylinder 1 is provided with an opening 11 connected to the horizontal release tube 4, and the microbial suspension is transported into the horizontal release tube 4 through the opening 11. Valves 12 are evenly arranged along the circumference in the opening 11, and the valves 12 are made of silicone material. Two adjacent valves 12 fit tightly together, so that in a normal state, multiple valves 12 close the opening 11 under their own elastic pressure. When the pressure increases, the pressure can force the adjacent valves 12 to separate and open the opening 11; a filter plate 13 is installed in the horizontal release tube 4 adjacent to the opening 11 to play a filtering role.

[0035] In this embodiment, the elastic pressure pushing device includes a tension spring 14, a pushing ring 15, and a pushing ball 16. The two ends of the tension spring 14 are connected to the filter plate 13 and the pushing ring 15 respectively. The tension spring 14 provides elastic tension for the pushing ring 15. When the pressure ends, the pushing ring 15 and the pushing ball 16 can be pulled to return to their original positions. The pushing ring 15 is provided with a groove 17 that cooperates with the pushing ball 16 on the side away from the opening 11. The pushing ball 16 can roll in the groove 17. The pushing ring 15 can provide some magnetic attraction for the pushing ball 16. The pushing ring 15 is magnetically connected to the pushing ball 16, and the pushing ball 16 is installed in the horizontal release tube 4. When the pushing ball 16 rolls along the horizontal release tube 4, the pushing ball 16 can contact the ball 6, so the ball 6 can be loosened in advance, which can facilitate the subsequent sliding limit plate 5 to act on the ball 6 and reduce the possibility of the device being stuck. The cooperation between the pushing ball 16 and the horizontal release tube 4 can also increase the sealing effect and reduce friction.

[0036] In this embodiment, an annular shell 18 is installed on the outer side of the horizontal release tube 4. A release space is formed between the annular shell 18 and the horizontal release tube 4. The microorganisms overflowing from the horizontal release hole 7 can enter the release space. The annular shell 18 corresponds to the horizontal release hole 7 one by one. A limiting hole 19 corresponding to the ball 6 is opened on the upper side of the annular shell 18 to prevent the ball 6 from being thrown out from the vicinity of the horizontal release hole 7. It can play a certain limiting role and ensure the integrity of the device after continuous use.

[0037] In this embodiment, the lower end of the release shell is connected to a vertical release tube 20, which extends downward in the vertical direction, and a plurality of vertical release holes 21 are evenly spaced on the surface of the vertical release tube 20 along the length direction of the vertical release tube 20. By providing the vertical release tube 20, microorganisms can be released into the soil at various locations in the vertical direction, and the release range can be increased.

[0038] In this embodiment, the vertical release hole 21 is connected to an inclined tube 22, a plurality of through holes 23 are opened on the surface of the inclined tube 22, a piston 24 is slidably installed in the inclined tube 22, and the piston 24 is connected to the inclined tube 22 through an elastic connection device 25. In a normal state, the piston 24 can close the through hole 23, thereby preventing soil impurities from blocking the through hole 23, so that the pressure increases when the microorganisms are released, and the pressure can act on the piston 24, and the piston 24 compresses the elastic connection device 25, so that the microorganisms can be released from the through hole 23 normally.

[0039] In this embodiment, the elastic support device includes a support plate 26 and a support spring 27. The support plate 26 is slidably installed in the horizontal release tube 4. The support plate 26 is connected to the outer end of the horizontal release tube 4 through the support spring 27. The support spring 27 provides elastic support force for the support plate 26, so that after the push ball 16 and the support plate 26 are separated, the support plate 26 can be restored to its original position, which is convenient for the next push. The support plate 26 is connected to the sliding limit plate 5.

[0040] In this embodiment, the release cylinder 1 includes a culture cylinder 28, an elastic cylinder 29 coaxially connected to the culture cylinder 28, and an extrusion assembly 30 for extruding the elastic cylinder 29. The culture cylinder 28 is located at the lower end of the elastic cylinder 29. When the elastic cylinder 29 is extruded, the internal pressure of the release cylinder 1 increases, which can provide pressure for the microorganisms to be released from the opening 11. A one-way air inlet 31 is installed at the upper end of the elastic cylinder 29. A one-way air inlet valve can be installed in the one-way air inlet 31 to facilitate subsequent air intake. It can be understood that in order to facilitate the monitoring of microorganisms, a temperature and humidity sensor is installed in the release cylinder 1, and a nozzle is also provided, etc., which can facilitate the addition of water to elute part of the microorganisms in the culture medium into a microbial suspension.

[0041] In an embodiment of the present invention, the extrusion assembly 30 includes a support frame, a motor, a first gear, a second gear, a first clamp and a second clamp. The support frame is fixed to the ground, the motor is installed on the support frame, the output end of the motor is connected to the first gear, the first gear and the second gear are meshed, the first gear and the second gear are rotated and installed on the support frame at the same time, the first clamp and the second clamp are respectively connected to the first gear and the second gear, and the first clamp and the second clamp are surrounded by the outside of the release cylinder 1.

[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
