Technical Field

[0001] The invention relates to the technical field of microbial strain cultivation, and more specifically, to a strain cultivation device for microbial fertilizer. Background Art

[0002] Microbial strain cultivation is a method of breeding microorganisms under artificial conditions. Microbial strains are cultivated according to the type of microorganism and its different requirements for environmental conditions such as nutrients, temperature, oxygen, water, pH, etc., and in combination with specific production and experimental requirements.

When using a culture device to cultivate microbial fertilizers, first of all, the culture medium is the basis for the cultivation of bacterial strains. It is composed of various nutrients and growth factors, which provide the necessary energy and nutrition for microorganisms. The appropriate culture medium can be selected and adjusted according to the characteristics of the microorganisms to promote their growth; after selecting a suitable culture medium, it needs to be prepared. The preparation process includes dissolving various nutrients together, adjusting the pH value, heating and sterilizing, etc. These steps are all to ensure the sterility of the culture medium and the appropriate pH value to ensure the growth and reproduction of the bacterial strains; after preparing the culture medium, the bacterial strains need to be inoculated into the culture medium. After inoculation, the culture medium needs to be placed in a constant temperature cultivation device for cultivation.

[0004] However, when the cultivation device sprays the culture solution on the soil mixed with microorganisms at a regular interval and in a fixed quantity, during the microbial strain cultivation process, when the incubator sprays the culture solution onto the microbial soil tray through the nozzle, due to the obstruction of the edge of the tray, the culture solution often cannot evenly and fully cover the microbial soil at the edge of the tray, resulting in the microorganisms in these areas being unable to obtain sufficient nutrition supply.

DETAILED DESCRIPTION

[0034] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0035] like Figure 1 - Fig.11 As shown, a bacterial strain cultivation device for microbial fertilizer includes: a microbial fertilizer cultivation box 11, wherein a plurality of tray racks 12 for placing trays containing microbial soil are fixedly arranged inside the microbial fertilizer cultivation box 11, microorganisms are mixed into the soil, the microbial soil is evenly spread in the microbial soil tray, and then the microbial soil tray is placed on the tray rack 12, and the microbial fertilizer is assisted to grow in the tray by the constant temperature and humidity equipment in the microbial fertilizer cultivation box 11;

[0036] A liquid application component 4 is disposed above each of the plurality of tray racks 12. The liquid application component 4 is used to uniformly spray the culture solution into the microbial soil tray. The liquid application component 4 includes a liquid pipe 41. A plurality of planar nozzles 42 are disposed at the output end of the liquid pipe 41. The planar nozzles 42 are used to spray the culture solution into the microbial soil tray in a plane. According to the growth requirements of the microbial strains, the liquid pipe 41 is driven by the driving component 2 to move uniformly above the microbial soil tray, so that the culture solution is uniformly sprayed from the planar nozzle 42 and sprayed on the microbial strain soil in the microbial soil tray, which is beneficial to the cultivation of the microbial fertilizer raw materials. Moreover, the side-by-side arrangement of the plurality of planar nozzles 42 is beneficial to reducing the phenomenon of repeated spraying, and the spraying is in a line from one side to the other side.

[0037] The plane nozzle 42 includes a limit plate 421 fixedly connected thereto, a rubber wall plate 422 penetrating the lower wall of the liquid pipe 41 is arranged on the limit plate 421, and a rubber sheet 423 fixed and sealed to the inner wall of the liquid pipe 41 is arranged around the rubber wall plate 422, and a secondary adjustment line 43 is fixedly arranged on the side of the limit plate 421 opposite to the direction of travel of the liquid pipe 41, and the secondary adjustment line 43 is used to control the plane nozzle 42 to gradually rotate as the liquid pipe 41 moves. As the liquid pipe 41 moves, the spray liquid of the plane nozzle 42 is sprayed onto the microbial soil support. When the culture liquid is at the edge of the tray, it is blocked by the side plate of the tray, and the culture liquid cannot be well sprinkled on the microbial soil at the edge. Therefore, when the liquid pipe 41 is about to move to the edge of the tray, a row of plane nozzles 42 are automatically adjusted to deflect in the direction of the liquid pipe 41, so as to achieve inclined spraying to the edge of the tray, reducing the phenomenon of affecting the growth of microbial strains due to uneven spraying of the culture liquid, and the sprayed culture liquid is always advanced in the form of a line, and there will be no repeated spraying, reducing the phenomenon of affecting the growth of microbial strains due to repeated spraying of the culture liquid;

[0038] At the same time, when the plane nozzle 42 stops spraying the microbial soil at the edge of the tray, the plane nozzle 42 is quickly rotated at a certain angle at the moment of stopping spraying, so as to quickly throw the plane nozzle 42, and throw the water droplets formed by the plane nozzle 42 at the moment of stopping spraying out of the range of the tray, so as to prevent the water droplets from falling into the tray, causing impact on the microbial soil and causing a change in the soil flatness, thereby affecting the growth of microbial strains;

[0039] A driving assembly 2 for driving the liquid passage tube 41 to move on the microbial soil tray is provided on one side of the tray frame 12;

[0040] An adaption component 3 is provided at one corner of the tray rack 12. The adaption component 3 is used to detect the placement position of the microbial soil tray and automatically control the liquid pipe 41 matched with the microbial soil tray to spray evenly.

[0041] The driving assembly 2 includes a partition plate 21 fixedly connected to the microbial fertilizer cultivation box 11, and a driving member 24 is arranged in the internal space of the partition plate 21 and the microbial fertilizer cultivation box 11. The power end of the driving member 24 is provided with a servo motor 23 located in the bottom space inside the microbial fertilizer cultivation box 11. The operation of the servo motor 23 drives the operation of the driving member 24, and the belt of the driving member 24 drives the rotation of the driving gear 201, so that the liquid pipe 41 passes through the microbial soil tray at a uniform speed. The partition plate 21 separates the contact ends of the driving member 24 and multiple driving gears 201 in an independent space.

[0042] A culture liquid tank 22 is fixedly arranged on one side of the partition plate 21 close to the rear wall of the microbial fertilizer cultivation box 11, and a water pump 25 connected to the culture liquid tank 22 is fixedly arranged on the rear wall of the microbial fertilizer cultivation box 11. The output end of the water pump 25 is fixedly connected to a valve 26 through a multi-way pipe. The culture liquid tank 22 is tightly attached to the rear wall of the microbial fertilizer cultivation box 11. The staff needs to add culture liquid to the culture liquid tank 22 regularly. Through the operation of the water pump 25, spraying can be carried out without opening the microbial fertilizer cultivation box 11. The culture liquid tank 22 in the microbial fertilizer cultivation box 11 can also make the environment where a large amount of culture liquid is located always in an environment most suitable for the growth of microbial strains.

[0043] A driving gear 201 is provided on the inner side of the belt of the driving member 24, and the driving gear 201 is meshed with the belt of the driving member 24. A driving screw 29 is fixedly provided on one side of the driving gear 201, and a threaded barrel 28 is provided on the driving screw 29. A support arm 27 parallel to the microbial soil tray is provided on one side of the threaded barrel 28, and the support arm 27 is used to drive the liquid pipe 41 to move above the microbial soil tray. The operation of the driving member 24 drives the driving gear 201 to rotate, and the driving screw 29 is driven to rotate by the driving gear 201, thereby driving the threaded barrel 28 to move along the driving screw 29, and the support arm 27 is driven by the threaded barrel 28 to pass through the microbial soil tray at a uniform speed, which is conducive to multiple flat nozzles 42 to evenly spray the culture solution on the microbial strains.

[0044] One end of the auxiliary adjustment line 43 away from the limiting plate 421 is connected to the main adjustment line 44, and one end of the main adjustment line 44 away from the auxiliary adjustment line 43 is fixedly provided with a pull-wire column 45, and the pull-wire column 45 passes through the support arm 27. At the same time, the pull-wire column 45 is slidingly connected to the support arm 27, and force heads 46 are fixedly provided at both ends of the pull-wire column 45. The sum of the length dimensions of the two force heads 46 and the pull-wire column 45 is greater than the width dimension of the support arm 27.

[0045] A metal sheet 47 is fixedly arranged on the inner wall of one of the two force-bearing heads 46 close to the travel direction of the support arm 27, and the wire-pulling column 45 includes a sub-column 402 fixedly connected thereto, and the diameter of the sub-column 402 is smaller than the diameter of the wire-pulling column 45. When the support arm 27 travels to the point where the force-bearing head 46 contacts the inner wall of the microbial fertilizer cultivation box 11, the force-bearing head 46 is squeezed as the support arm 27 continues to travel, so that the force-bearing head 46 pushes the wire-pulling column 45 to slide, and the main adjustment line 44 is relaxed by the sliding of the wire-pulling column 45, and the main adjustment line 44 is relaxed while the multiple sub-adjustment lines 43 are adjusted. Relaxation is performed, and the rubber wall plate 422 is extended under the impact of the culture fluid pressure in the liquid pipe 41. Since the rubber sheet 423 is elastic, the flat nozzle 42 can be tilted in the opposite direction of travel, and a row of flat nozzles 42 can be automatically adjusted to deflect in the direction of travel of the liquid pipe 41, so as to achieve inclined spraying to the edge of the tray, reducing the phenomenon of uneven spraying of the culture solution that affects the growth of microbial strains, and the sprayed culture solution is always advanced in the form of a line, and there will be no repeated spraying, thereby reducing the phenomenon of repeated spraying of the culture solution that affects the growth of microbial strains.

[0046] A magnetic ring 401 that is attracted to the metal sheet 47 is fixedly provided on one side of the support arm 27 close to its moving direction, and a resistance ring 49 is fixedly provided on the inner side of the magnetic ring 401, and the inner diameter of the resistance ring 49 is the same as the diameter of the pull-wire post 45. The resistance ring 49 increases the resistance to the sliding of the pull-wire post 45. When the support arm 27 moves to the point where the flat nozzle 42 has completed spraying the edge of the tray, the flat nozzle 42 also reaches a position above the edge of the tray, and the secondary post 402 is not in contact with the resistance ring 49. In addition, the suction force of the magnetic ring 401 on the metal sheet 47 can instantly relax the remaining main adjustment line 44 and secondary adjustment line 43, and quickly rotate the flat nozzle 42 to a certain angle in an instant, thereby playing the role of quickly throwing the flat nozzle 42, and throwing the water droplets formed by the flat nozzle 42 at the moment of stopping spraying out of the range of the tray, preventing the water droplets from falling into the tray, causing an impact on the microbial soil to form a change in the soil flatness, thereby affecting the growth of microbial strains.

[0047] The adaptation component 3 includes a force-bearing plate 33, on which a slider 34 is provided which penetrates the pallet rack 12, and the force-bearing plate 33 and the pallet rack 12 form a sliding structure through the slider 34, and a spring piece 35 is fixedly provided below the slider 34. The pallet will press down on the force-bearing plate 33 on which the pallet rack 12 is placed.

[0048] A pull wire 32 is fixedly set on one side of the slider 34, and a support frame 31 is set at the end of the pull wire 32 away from the slider 34. The support frame 31 includes a support plate 37 rotatably connected thereto, and the support plate 37 is in a herringbone shape. At the same time, two arm plates of the support plate 37 are rotatably connected through a torsion spring column, and a spring piece 2 38 fixedly connected to the pull wire 32 is fixedly connected between the two arm plates of the support plate 37. When the slider 34 slides down, the pull wire 32 can be relaxed, and at the same time, the support plate 37 can be closed under the elastic force of the spring piece 2 38, so that the drive gear 201 and the drive member 24 belt are meshed with each other. For the slider 34 that is not pressed down, the pull wire 32 always tightens the spring piece 2 38, and the drive member 24 belt is stretched open through the support plate 37, so that the drive member 24 belt does not contact the drive gear 201, and the support arm 27 without a tray placed thereon will not move.

[0049] A switch 36 is provided below the spring piece 35, and the switch 36 is connected to the valve 26 through a wire. The output end of the valve 26 is provided with a telescopic water pipe 48 which is interconnected with the liquid pipe 41. The tray is placed on which tray rack 12, and the tray presses down on which force plate 33, so that the force plate 33 triggers the corresponding switch 36, and the corresponding valve 26 is controlled by the switch 36 to work, and finally the culture fluid flows into the corresponding liquid pipe 41. The corresponding liquid pipe 41 where no tray is placed will not supply liquid.

[0050] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are protected by the present embodiment.
