Description

Technical Field

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

[0002] Microbial strain cultivation is a method of multiplying microorganisms under artificial conditions. According to the types of microorganisms and their different requirements for environmental conditions such as nutrients, temperature, oxygen, moisture, and pH value, and in connection with the specific requirements in production and experiments, microbial strains are cultivated.

[0003] Microbial fertilizers contain a large number of microorganisms. Through the life activities of the microorganisms in the soil, the nutritional conditions of crops are improved. When using a cultivation device to cultivate microbial fertilizers, first of all, the culture medium is the basis for strain cultivation. It is composed of various nutrients and growth factors, providing necessary energy and nutrients for microorganisms. Appropriate culture media can be adjusted according to the characteristics of microorganisms to promote their growth. After selecting a suitable culture medium, preparation is required. 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 strains. After preparing the culture medium, the 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 onto the microbial soil tray at regular intervals and in a fixed quantity during the cultivation of microbial strains, during the cultivation process of microbial strains, when the cultivation chamber sprays the culture solution onto the microbial soil tray through a nozzle, due to the obstruction of the tray edge, the culture solution often cannot evenly and fully cover the microbial soil at the tray edge, resulting in the microorganisms in these areas not being able to obtain sufficient nutrient supply. For this reason, we propose a device for cultivating strains for microbial fertilizer. Summary of the Invention

[0005] The present invention provides a device for cultivating strains for microbial fertilizer, which solves the technical problem in the related art that during the cultivation process of microbial strains, when the cultivation chamber sprays the culture solution onto the microbial soil tray through a nozzle, due to the obstruction of the tray edge, the culture solution often cannot evenly and fully cover the microbial soil at the tray edge, resulting in the microorganisms in these areas not being able to obtain sufficient nutrient supply.

[0006] The present invention provides a strain cultivation device for microbial bacterial fertilizer, comprising: a microbial bacterial fertilizer cultivation box, wherein a plurality of tray racks for placing trays filled with microbial soil are fixedly arranged inside the microbial bacterial fertilizer cultivation box, and a liquid application assembly is arranged above each of the plurality of tray racks. The liquid application assembly is used for uniformly spraying a culture solution onto the microbial soil trays.

[0008] A driving assembly for driving the liquid delivery pipe to move on the microbial soil trays is arranged on one side of the tray rack;

[0009] An adaptation assembly is arranged at a corner of the tray rack. The adaptation assembly is used for detecting the placement position of the microbial soil trays and automatically controlling the liquid delivery pipes matched with the microbial soil trays to perform uniform spraying.

[0010] Further, the driving assembly includes a partition plate fixedly connected to the microbial bacterial fertilizer cultivation box. A driving member is arranged in the inner space between the partition plate and the microbial bacterial fertilizer cultivation box. The power end of the driving member is provided with a servo motor located in the bottom space inside the microbial bacterial fertilizer cultivation box.

[0011] Further, a culture solution tank is fixedly arranged on one side of the partition plate close to the rear wall of the microbial bacterial fertilizer cultivation box. A water pump fixedly connected to the culture solution tank is arranged on the rear wall of the microbial bacterial fertilizer cultivation box. The output end of the water pump is fixedly connected with a valve through a multi-way pipe.

[0012] Further, a driving gear is arranged inside the driving member belt, and the driving gear meshes with the driving member belt. A driving lead screw is fixedly arranged on one side of the driving gear. A threaded cylinder is arranged on the driving lead screw. A support arm parallel to the microbial soil trays is arranged on one side of the threaded cylinder, and the support arm is used for driving the liquid delivery pipe to move above the microbial soil trays.

[0013] Further, one end of the secondary adjustment wire far away from the limiting piece is connected with a main adjustment wire. A wire pulling column is fixedly arranged at one end of the main adjustment wire far away from the secondary adjustment wire. The wire pulling column penetrates through the support arm and is slidably connected with the support arm at the same time. Force receiving heads are fixedly arranged at both ends of the wire pulling column. The total length dimension of the two force receiving heads and the wire pulling column is greater than the width dimension of the support arm.

[0014] Further, a metal sheet is fixedly arranged on the inner wall of one of the force - receiving heads close to the advancing direction of the support arm. The wire - pulling column includes a secondary column fixedly connected thereto, and the diameter of the secondary column is smaller than that of the wire - pulling column.

[0015] Further, a magnetic ring that adsorbs to the metal sheet is fixedly arranged on one side of the support arm close to its advancing direction. A resistance ring is fixedly arranged inside the magnetic ring, and the inner diameter of the resistance ring is the same as the diameter of the wire - pulling column, increasing the resistance of the wire - pulling column to slide through the resistance ring.

[0016] Further, the adaptation assembly includes a force - receiving plate. A slider penetrating through the tray rack is arranged on the force - receiving plate, and the force - receiving plate and the tray rack form a sliding structure through the slider.

[0019] The beneficial effects of the present invention are as follows:

[0020] When the liquid - passing pipe is about to move to the edge position of the tray, the present invention automatically adjusts a row of flat nozzles to deflect in the advancing direction of the liquid - passing pipe, so as to spray obliquely to the edge of the tray, reducing the phenomenon that affects the growth of microbial strains caused by uneven spraying of the culture solution. And the sprayed culture solution always advances in a linear form, without the phenomenon of repeated spraying, reducing the phenomenon that affects the growth of microbial strains caused by repeated spraying of the culture solution.

[0021] When the flat nozzles finish spraying the microbial soil at the edge position of the tray obliquely and stop spraying, the flat nozzles quickly rotate a certain angle immediately, playing the role of quickly shaking the flat nozzles, and throwing the water droplets formed at the moment of stopping spraying out of the range of the tray, preventing the water droplets from falling into the tray and causing changes in the soil flatness due to the impact on the microbial soil, thereby affecting the growth of microbial strains.

Detailed Embodiments

[0034] Reference will now be made to example embodiments to discuss the subject matter described herein. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein, and that changes can be made to the functions and arrangements of the elements discussed without departing from the scope of protection of the content of this specification. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0035] As Figure 1 - Figure 11 shown, a microbial inoculum cultivation device for microbial fertilizer includes: a microbial fertilizer cultivation box 11, and a plurality of tray racks 12 for placing trays filled with microbial soil are fixedly arranged inside the microbial fertilizer cultivation box 11. The microorganisms are doped in the soil, and the microbial soil is evenly spread in the microbial soil trays, and then the microbial soil trays are placed on the tray racks 12. The constant temperature and humidity equipment in the microbial fertilizer cultivation box 11 assists the growth of the microbial fertilizer in the trays;

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

[0037] The flat nozzle 42 includes a limiting piece 421 fixedly connected thereto. A rubber wall plate 422 penetrating through the lower wall of the liquid delivery pipe 41 is arranged on the limiting piece 421. Rubber sheets 423 fixedly and sealingly connected to the inner wall of the liquid delivery pipe 41 are arranged around the rubber wall plate 422. A secondary adjustment wire 43 is fixedly arranged on the side of the limiting piece 421 opposite to the advancing direction of the liquid delivery pipe 41, and the secondary adjustment wire 43 is used to control the gradual rotation of the flat nozzle 42 as the liquid delivery pipe 41 advances. As the liquid delivery pipe 41 moves, when the liquid sprayed by the flat nozzle 42 reaches the edge position of the microbial soil tray, it is blocked by the side plate of the tray, and the culture solution cannot be well sprayed on the microbial soil at the edge. Therefore, when the liquid delivery pipe 41 is about to move to the edge position of the tray, a row of flat nozzles 42 is automatically adjusted to deflect in the advancing direction of the liquid delivery pipe 41, so as to achieve inclined spraying to the edge of the tray, reduce the phenomenon of affecting the growth of the microbial inoculum caused by uneven spraying of the culture solution, and the sprayed culture solution always advances in a line form, and there will be no phenomenon of repeated spraying, reducing the phenomenon of affecting the growth of the microbial inoculum caused by repeated spraying of the culture solution;

[0038] At the moment when the spraying stops after the flat nozzle 42 has obliquely sprayed the microbial soil at the edge position of the tray, quickly rotate the flat nozzle 42 by a certain angle, which serves to quickly flick the flat nozzle 42, and fling the water droplets formed at the moment when the spraying of the flat nozzle 42 stops out of the range of the tray, preventing the water droplets from dripping into the tray and causing changes in the soil flatness due to the impact on the microbial soil, thus affecting the growth of the microbial strains;

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

[0040] An adaptation assembly 3 is provided at a corner of the tray rack 12. The adaptation assembly 3 is used to detect the placement position of the microbial soil tray and automatically control the liquid delivery pipe 41 that matches the microbial soil tray to perform uniform spraying.

[0041] The driving assembly 2 includes a partition plate 21 fixedly connected to the microbial fertilizer cultivation box 11. A driving member 24 is provided in the internal space between the partition plate 21 and the microbial fertilizer cultivation box 11. A servo motor 23 is provided at the power end of the driving member 24 in the bottom space inside the microbial fertilizer cultivation box 11. By the operation of the servo motor 23, the driving member 24 is driven to operate. The driving gear 201 is rotated by the belt of the driving member 24, so that the liquid delivery pipe 41 passes over the microbial soil tray at a uniform speed. The partition plate 21 separates the contact ends of the driving member 24 and the plurality of driving gears 201 in independent spaces.

[0042] A culture solution tank 22 is fixedly provided on one side of the partition plate 21 close to the rear wall of the microbial fertilizer cultivation box 11. A water pump 25 communicated with the culture solution tank 22 is fixedly provided 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 solution tank 22 is closely attached to the rear wall of the microbial fertilizer cultivation box 11. The staff needs to regularly add culture solution to the culture solution tank 22, and spraying can be carried out without opening the microbial fertilizer cultivation box 11 through the operation of the water pump 25. The culture solution tank 22 is in the microbial fertilizer cultivation box 11, and can also keep the environment where a large amount of culture solution is located in the most suitable environment for the growth of microbial strains all the time.

[0043] On the inner side of the belt of the driving member 24, a driving gear 201 is provided, and the driving gear 201 meshes with the belt of the driving member 24. On one side of the driving gear 201, a driving lead screw 29 is fixedly provided. A threaded barrel 28 is arranged on the driving lead screw 29. On one side of the threaded barrel 28, a support arm 27 parallel to the microbial soil tray is provided, and the support arm 27 is used to drive the liquid delivery pipe 41 to move above the microbial soil tray. The operation of the driving member 24 drives the driving gear 201 to rotate, drives the driving lead screw 29 to rotate through the driving gear 201, thereby driving the threaded barrel 28 to travel along the driving lead screw 29, and drives the support arm 27 to pass evenly over the microbial soil tray through the threaded barrel 28, which is beneficial for a plurality of flat nozzles 42 to evenly spray the culture solution onto the microbial strains.

[0044] One end of the secondary adjustment wire 43 away from the limit piece 421 is connected to the main adjustment wire 44. One end of the main adjustment wire 44 away from the secondary adjustment wire 43 is fixedly provided with a wire pulling post 45, and the wire pulling post 45 penetrates through the support arm 27. At the same time, the wire pulling post 45 is slidably connected to the support arm 27. Force receiving heads 46 are fixedly provided at both ends of the wire pulling post 45. The total length dimension of the two force receiving heads 46 and the wire pulling post 45 is greater than the width dimension of the support arm 27.

[0045] A metal sheet 47 is fixedly provided on the inner wall of one of the two force receiving heads 46 close to the advancing direction of the support arm 27. The wire pulling post 45 includes a secondary post 402 fixedly connected thereto. The diameter dimension of the secondary post 402 is smaller than the diameter dimension of the wire pulling post 45. When the support arm 27 advances to the point where the force receiving head 46 contacts the inner wall of the microbial fertilizer cultivation box 11, as the support arm 27 continues to advance, it squeezes the force receiving head 46, causing the force receiving head 46 to push the wire pulling post 45 to slide. By the sliding of the wire pulling post 45, the main adjustment wire 44 is relaxed. While the main adjustment wire 44 is relaxed, a plurality of secondary adjustment wires 43 are relaxed. Under the impact of the pressure of the culture solution in the liquid delivery pipe 41, the rubber wall plate 422 extends. Because the rubber sheet 423 has elasticity, the flat nozzle 42 can be tilted in the opposite direction of the advance, automatically adjusting a row of flat nozzles 42 to deflect in the advancing direction of the liquid delivery pipe 41, so as to spray obliquely to the edge of the tray, reducing the phenomenon that the growth of microbial strains is affected by uneven spraying of the culture solution, and the sprayed culture solution always advances in a linear form, without the phenomenon of repeated spraying, reducing the phenomenon that the growth of microbial strains is affected by repeated spraying of the culture solution.

[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 has described the embodiments of this example, but this example is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of this example, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this example.
