Description

Technical Field

[0001] The invention relates to the technical field of microbial preparation inoculation, and in particular to an automatic inoculation device for agricultural microbial preparations. Background Art

[0002] When inoculating existing agricultural microbial preparations, the bacteria are prepared into a bacterial suspension, and then the bacterial suspension is atomized into tiny particles by a spray device and evenly sprayed on the surface of the culture medium (such as biological organic fertilizer). In order to maximize the inoculation efficiency and economic benefits, it is necessary to store as many agricultural microbial preparations as possible for inoculation. Therefore, in order to maximize the inoculation efficiency and economic benefits, the existing technology uses a multi-layer material vehicle with a multi-layer structure for inoculation. See Figure 1 The prior art has a multi-layer material vehicle with multi-layer pallets.

[0003] However, in the use of the existing multi-layer material vehicle with multi-layer tray, on the one hand, the multi-layer material vehicle with multi-layer structure is not convenient for manual operation and inoculation due to its complex structure, resulting in a slow manual inoculation speed, which in turn leads to a reduction in inoculation efficiency, thereby affecting the overall production efficiency. On the other hand, it is difficult to accurately control the amount of bacterial liquid during the inoculation process, and the inoculation amount of the bacterial liquid is unstable, which in turn affects the final inoculation quality. In addition, since some of the culture media on the tray, such as the surface of the biological organic fertilizer, are not in a flat state, it is difficult to spray the agricultural microbial preparation evenly and comprehensively during spraying, and there is a spraying dead angle.

[0004] Therefore, the present invention provides an automatic inoculation device for agricultural microbial preparations to solve the above problems. Summary of the invention

[0028] The disclosed embodiments are intended to solve the problems of low efficiency of artificial inoculation of existing multi-layer agricultural microbial preparations, unstable bacterial liquid dosage, and easy existence of dead corners during spraying. In view of this, the embodiment of the present disclosure proposes an automatic inoculation device for agricultural microbial preparations, including a frame component 1, a mobile inoculation component 2 and a flow control component 3, the frame component 1 includes an outer frame 11, the outer frame 11 is made of 40mm*80mm industrial aluminum, the mobile inoculation component 2 is slidably installed in the outer frame 11, and the flow control component 3 for controlling the flow of bacterial liquid in the mobile inoculation component 2 is fixedly installed in the mobile inoculation component 2; the mobile inoculation component 2 includes an inoculation nozzle 21, an inoculation guide tube 22, an inoculation connecting tube 23, a first slider 24, a ball screw 25, a horizontal reciprocating servo motor 26, a screw linkage gear 261 and a power synchronization chain 262, the outer frame 11 is horizontally installed with the inoculation nozzle 21 along the vertical direction of movement, the two ends of the inoculation nozzle 21 are respectively connected to one end of the inoculation guide tube 22, and the other end of the inoculation guide tube 22 is vertically connected to the vertical inoculation connecting tube 23. The ends of the inoculation connecting pipes 23 on both sides merge into a main valve for control. A first slider 24 is fixedly installed on the surface of the inoculation connecting pipe 23. A ball screw 25 is rotatably installed on the inner side of the outer frame 11 close to the inoculation guide pipe 22. A horizontal reciprocating servo motor 26 is fixedly installed on the top of the outer frame 11 perpendicular to the side of the ball screw 25. The output shaft of the horizontal reciprocating servo motor 26 and the ends on the same side of the ball screw 25 are fixedly installed with a screw linkage gear 261, and a power synchronization chain 262 is installed between adjacent screw linkage gears 261 in the horizontal direction. The inoculation connecting pipes 23 on both sides merge into a main valve for synchronous control of opening and closing.

[0029] It should be noted that a receiving object is also placed on the moving path of the mobile inoculation component to receive the bacterial liquid sprayed by the inoculation nozzle 21 for subsequent fermentation process treatment. In the embodiment of the present disclosure, the receiving object is a multi-layer material vehicle 5 on which a tray 51 is placed in the prior art, so that the tray 51 can be moved and transported after receiving the bacterial liquid sprayed by the inoculation nozzle 21. It should be noted here that the multi-layer material vehicle 5 and the tray 51 are both extremely mature technologies in the prior art, so they will not be described in detail.

[0030] By starting the horizontal reciprocating servo motor 26, the horizontal reciprocating servo motor 26 drives the screw linkage gears 261 of the ball screws 25 on both sides to rotate through the screw linkage gears 261 at the end, thereby driving the ball screw to rotate and causing the first slider 24 to move on the surface of the ball screw 25, and then driving the inoculation nozzle 21, the inoculation guide tube 22 and the inoculation connecting tube 23 to move horizontally to the tray 51 of the multi-layer material vehicle 5 through the first slider 24 for spraying, so that the inoculation nozzle 21 can flexibly adjust the spraying position for mobile spraying, thereby realizing dynamic spraying to avoid dead corners for spraying and inoculation.

[0031] The inoculation nozzle 21 is a pair of evenly distributed pipes with a porous structure, which are fixedly spliced ​​by an intermediate joint. The length of the inoculation nozzle 21 can be customized, and the bacterial liquid is evenly sprayed through the porous structure of the inoculation nozzle 21. The bacterial liquid enters from the inoculation connecting pipes 23 on both sides and is then input into the bacterial liquid guide pipe, and finally sprayed out from the porous structure in the bacterial liquid nozzle for spraying.

[0032] A stable transverse pipe 27 is fixedly installed between the bottoms of the two inoculation connecting pipes 23. The stable transverse pipe 27 is used to ensure the structural stability of the inoculation connecting pipes 23 on both sides, thereby ensuring the structural stability of the inoculation guide pipe 22 and the inoculation nozzle 21 through the stable inoculation connecting pipes 23.

[0033] The frame assembly 1 further includes a linear load slide rail 12 and a second slider 13. The linear load slide rail 12 is fixedly mounted on the bottom of the outer frame 11, and the second slider 13 sleeved on the surface of the linear load slide rail 12 is fixedly mounted on the bottom of the stabilizing cross tube 27. When the mobile inoculation assembly 2 moves horizontally, the second slider 13 slides on the surface of the linear load slide rail 12, thereby supporting the mobile inoculation assembly 2 to move through the second slider 13, thereby ensuring that the mobile inoculation assembly 2 moves smoothly, and the mobile inoculation assembly 2 moves horizontally to realize mobile spraying of bacterial liquid.

[0034] The flow control assembly 3 includes a linkage rod 31, a linkage valve 32, a linkage valve servo motor 33, a linkage valve synchronous gear 34 and a linkage valve synchronous chain 35. A linkage rod 31 is rotatably installed between the two vertical bacteria inoculation connecting pipes 23 and is perpendicular to the bacteria inoculation guide pipe 22. A linkage valve 32 is installed at the contact between the linkage rod 31 and the bacteria inoculation guide pipe 22. A servo motor 33 for driving the linkage rod 31 to rotate the linkage valve is fixedly installed below the horizontal reciprocating servo motor 26. A linkage valve synchronous gear 34 is fixedly installed on the output shaft of the linkage valve servo motor 33 and the surface of the linkage rod 31. A linkage valve synchronous chain 35 is installed between the output shaft of the linkage valve servo motor 33 and the linkage valve synchronous gear 34.

[0035] After starting the linkage valve servo motor 33, the linkage valve servo motor 33 drives the linkage rod 31 to rotate through the linkage valve synchronization chain 35 and the linkage valve synchronization gear 34. When the linkage rod 31 rotates, the opening and closing degree of the linkage valve 32 can be controlled, thereby controlling the flow rate of the bacterial liquid in the inoculation guide tube 22, and further realizing the control of the output of the bacterial liquid spraying.

[0036] The inoculation nozzles 21 and the inoculation guide tubes 22 are installed horizontally in multiple numbers in the vertical direction, and the two ends of the multiple inoculation nozzles 21 are respectively connected to one end of the multiple inoculation guide tubes 22, thereby forming a multi-layer structure, so that the multiple inoculation nozzles 21 in the vertical direction correspond to the multi-layer trays 51 of the multi-layer material vehicle 5 in the prior art. The other ends of the multiple inoculation guide tubes 22 are respectively connected to the vertical inoculation connecting tubes 23, and the linkage rods 31 are installed in multiple numbers and are perpendicular to the inoculation guide tubes 22 at the same height. The surfaces of the multiple linkage rods 31 are fixedly installed with linkage valve synchronization gears 34, and linkage valve synchronization chains 35 are installed between adjacent linkage valve synchronization gears 34.

[0037] The multiple inoculation nozzles 21 installed horizontally along the vertical direction can spray the bacterial liquid synchronously at different horizontal heights. After the bacterial liquid enters from the inoculation connecting pipe, it enters the inoculation guide pipes 22 of different horizontal heights respectively, and then enters the inoculation nozzles 21 of the same height from the inoculation guide pipes 22, so that the hole structures of the multiple inoculation nozzles 21 are sprayed synchronously, thereby improving the inoculation efficiency. For the multiple inoculation nozzles 21 installed horizontally in the vertical direction, the receiving object in the embodiment of the present disclosure is a multi-layer material vehicle 5 with multi-layer trays 51 placed in the prior art, and each layer of trays is individually located under a inoculation nozzle 21 for receiving, so that the inoculation of multiple layers can be achieved simultaneously when the multi-layer inoculation nozzles 21 spray at the same time, thereby improving the inoculation efficiency.

[0038] The mobile inoculation component 2 includes a horizontal motion auxiliary guide rail 28 and a balancing motion guide 29. The horizontal motion auxiliary guide rail 28 is used to assist the mobile inoculation component 2 in horizontal reciprocating motion. The outer frame 11 is fixedly installed with the horizontal motion auxiliary guide rail 28 on both sides perpendicular to the inoculation nozzle 21. A third slider 281 is fixedly installed above the first slider 24 on the surface of the inoculation connecting pipe 23. The outer frame 11 is fixedly installed with the balancing motion guide 29 above the ball screw 25.

[0039] While the horizontal reciprocating servo motor drives the inoculation nozzle 21, the inoculation guide tube 22 and the inoculation connecting tube 23 to move horizontally via the ball screw 25, the third slider 281 slides on the surface of the horizontal motion auxiliary guide rail 28, thereby preventing the mobile inoculation assembly 2 from shifting or shaking during horizontal movement.

[0040] The balancing motion guide 29 includes a support arm 291 and an auxiliary wheel 292. A plurality of support arms 291 are fixedly mounted on the outer frame 11 along the height direction. Two auxiliary wheels 292 are symmetrically mounted in the support arm 291. The inoculation guide tube 22 is placed between the two auxiliary wheels 292. During the movement of the inoculation guide tube 22, the inoculation guide tube 22 contacts the auxiliary wheels 292 on the upper and lower sides, thereby ensuring that the inoculation guide tube 22 remains stable during the movement to avoid deviation through the auxiliary wheels 292 on the upper and lower sides.

[0041] The frame assembly 1 also includes a positioning groove connecting plate 14 and a material vehicle inoculation positioning groove 15. A positioning groove connecting plate 14 that is perpendicular to the linear load slide rail 12 is fixedly installed on the moving path of the mobile inoculation assembly 2. A material vehicle inoculation positioning groove 15 that is perpendicular to the positioning groove connecting plate 14 is fixedly installed on the side of the positioning groove connecting plate 14 away from the outer frame 11. The material vehicle inoculation positioning groove 15 is made of 5mm stainless steel and is used to assist the AGV forklift to accurately position the four supporting feet of the multi-layer material vehicle 5 in the prior art into the material vehicle inoculation positioning groove 15, prevent the multi-layer material vehicle 5 from being shifted when it is naturally placed, and play a stabilizing role during automatic inoculation. The positioning groove connecting plate 14 is used to fix the material vehicle inoculation positioning groove 15 with the outer frame 11, which plays a stabilizing role, thereby ensuring that the multi-layer material vehicle 5 and the tray 51 on its surface are stable during the horizontal movement and spraying of the mobile inoculation assembly 2.

[0042] It is worth reiterating that see Figure 1 A multi-layer pallet 51 is fixedly arranged on the multi-layer material vehicle 5, and each pallet 51 stores a microbial preparation. The AGV forklift, the multi-layer material vehicle 5, the multi-layer pallet 51 and the microbial preparation are all extremely mature technologies in the prior art, so they will not be described in detail.

[0043] The outer frame 11 is fixedly installed with a control box 4 for controlling the movement of the mobile inoculation component 2 and the entry of the bacterial liquid for spraying on either side of the vertical direction of the mobile inoculation component. The control box 4 is composed of a control box 4 body and a control box 4 shell; a servo motor driver, a PLC, a digital output signal module, a 24V power supply, and a circuit breaker electrically connected to each other are fixedly installed in the control box 4 body; a button switch and a buzzer electrically connected to each other are fixedly installed on the control box 4 shell, and the button switch includes a disinfection button, an inoculation button, and a cleaning button. The PLC is a programmable logic controller PLC.

[0044] It should be noted that the models, structures and electrical connections between the servo motor driver, PLC, digital output signal module, 24V power supply, circuit breaker, push button switch and buzzer adopt the existing technology and will not be elaborated here.

[0045] Working principle: When starting bacterial liquid inoculation, the multi-layer material vehicle 5 is placed along the material vehicle inoculation positioning groove 15 by the AGV forklift, and then the horizontal reciprocating servo motor 26 is started by the control box 4. The horizontal reciprocating servo motor 26 drives the ball screw 25 to rotate through the screw linkage gear of the output shaft and the power synchronization chain 262, so that the first slider 24 drives the inoculation connecting pipe 23 to move horizontally along the ball screw 25. The horizontal movement of the inoculation connecting pipe 23 drives the inoculation guide pipe 22 and the inoculation nozzle 21 to move horizontally to the top of the tray 51 of the multi-layer material vehicle 5, and the multi-layer inoculation nozzle 21 corresponds to the multi-layer tray 51. In the process of the inoculation guide pipe 22 and the inoculation nozzle 21 moving horizontally to the top of the tray 51 of the multi-layer material vehicle 5, the bacterial liquid enters the multiple inoculation guide pipes 22 from the inoculation connecting pipe 23, and is sprayed toward the surface of the tray 51 of the multi-layer material vehicle 5 from the hole-shaped structure in the multiple inoculation nozzles 21 to achieve inoculation.

[0046] While the bacteria inoculation connecting pipe 23, the bacteria inoculation guide pipe 22 and the bacteria inoculation nozzle 21 move horizontally, the second slider 13 on the stable transverse pipe 27 supports the mobile bacteria inoculation component 2 to move along the linear load slide rail 12, and the third slider 281 on the bacteria inoculation connecting pipe 23 moves along the horizontal motion auxiliary guide rail 28, thereby ensuring that the bacteria inoculation mobile bacteria inoculation component 2 can move stably to avoid deviation or shaking. At the same time, the bacteria inoculation guide pipe 22 moves along the auxiliary wheel 292 in the balancing motion guide 29, thereby further ensuring that the mobile bacteria inoculation component 2 remains stable during the movement to avoid deviation or shaking.

[0047] During the process of bacterial liquid inoculation and the horizontal movement of the mobile inoculation assembly 2, the linkage valve servo motor 33 is started by the control box 4, and the linkage valve servo motor 33 drives multiple linkage rods 31 to rotate synchronously through the linkage valve synchronization gear 34 and the linkage valve synchronization chain 35 at the end, so that the opening and closing of the linkage valve 32 is controlled by the rotation of the linkage rod 31, thereby controlling the flow of bacterial liquid in the inoculation guide tube 22, and then controlling the amount of bacterial liquid sprayed in the inoculation nozzle 21. In addition, the flow of bacterial liquid can be sprayed as needed during the horizontal movement of spraying bacterial liquid for inoculation, thereby ensuring the initial amount of bacteria to ensure the inoculation effect.

[0048] In addition to the proposed agricultural microbial preparation automatic inoculation device, the disclosed embodiment also proposes a control method for the agricultural microbial preparation automatic inoculation device, the method steps are as follows: S1: after the equipment is turned on, first connect the inoculation connecting pipe 23 to the high-temperature steam end, then press the disinfection button on the outer shell of the control box 4 and send a disinfection instruction to the PLC; S2: After receiving the disinfection instruction, the PLC sends an instruction indicating that disinfection preparation is completed to the control center; S3: After receiving the disinfection preparation completion instruction, the control center sets a predetermined disinfection time and sends a disinfection start instruction to the PLC; S4: The PLC receives a sterilization start instruction from the control center, and high-temperature steam enters the inoculation connecting pipe 23 to automatically perform a sterilization process for a predetermined time; S5: After the sterilization process of the bacteria inoculation connecting pipe 23 with a preset time length is completed, the PLC controls the buzzer to sound; S6: After hearing the buzzer, the staff manually releases the disinfection button; S7: Connect the bacteria inoculation connecting pipe 23 to the bacteria liquid tank, and press the bacteria inoculation button to send a bacteria inoculation instruction to the PLC; S8: After receiving the inoculation instruction, the PLC sends an inoculation preparation completion instruction to the control center; S9: After receiving the instruction that the inoculation is ready, the control center issues a command to start inoculation; S10: The PLC receives the start inoculation instruction from the control center, and the bacterial liquid enters the inoculation connecting pipe 23 to automatically start the inoculation process; S11: When the inoculation process is completed, the staff manually releases the inoculation button; S12: The staff then connects the inoculation connecting pipe 23 to the tap water end and presses the cleaning button to send a cleaning instruction to the PLC; S13: After receiving the cleaning instruction, the PLC sends a cleaning preparation completion instruction to the control center; S14: After receiving the cleaning preparation completion instruction, the control center sets a predetermined cleaning time and sends a start cleaning command to the PLC; S15: After the PLC receives the start cleaning instruction from the control center, tap water enters the bacteria inoculation connecting pipe 23 and automatically performs a cleaning process for a predetermined time; S16: When the cleaning time of the inoculation device is up, the PLC will control the buzzer to sound; S17: After hearing the buzzer, the staff manually releases the cleaning button; S18: The staff then connects the bacteria inoculation connecting pipe 23 to the high-temperature steam end, and then presses the disinfection button to send a disinfection instruction to the PLC; S19: After receiving the disinfection instruction, the PLC sends a disinfection preparation completion instruction to the control center; S20: After receiving the disinfection preparation completion instruction, the control center sets the disinfection time to a predetermined time and sends a disinfection start instruction to the PLC; S21: After the PLC receives the start disinfection instruction from the control center, high-temperature steam enters the bacteria-inoculating connecting pipe 23 to automatically perform the disinfection process for a predetermined time; S22: The inoculation device performs high-temperature sterilization. When the predetermined sterilization time is reached, the PLC controls the buzzer to sound; S23: After hearing the buzzer, the staff manually releases the "disinfection" button; S24: Shut down and cut off power.

[0049] The disinfection operation process in step S4 is as follows: S41: The control center sets a predetermined disinfection time; S42: The PLC receives the predetermined disinfection time set by the control center; S43: PLC controls the linkage valve 32 to open; S44: After the predetermined disinfection time is up, the PLC controls all linkage valves 32 to close; S45: PLC controls the buzzer to sound.

[0050] The inoculation operation process in step S10 is as follows: S101: PLC controls the linkage valve 32 to initialize the opening and closing degree of the linkage valve 32; S102: PLC controls the horizontal reciprocating servo motor 26 to drive the mobile inoculation assembly 2 to the starting end of one side of the material tray; S103: PLC controls the linkage valve 32 to adjust the opening and closing degree to a preset angle; S104: PLC continues to control the horizontal reciprocating servo motor 26 to drive the mobile inoculation assembly 2 to reach the other end of the material tray; S105: After the inoculation process is completed, the PLC closes the linkage valve 32 and controls the horizontal reciprocating servo motor 26 to drive the mobile inoculation assembly 2 to reach the starting end position.

[0052] Embodiment 2: Based on Embodiment 1, only the differences from Embodiment 1 are described below.

[0053] The inoculation nozzles 21 are horizontally arranged in a plurality along the moving direction of the mobile inoculation assembly, and the plurality of inoculation nozzles 21 are all connected to the inoculation guide tube 22, and the plurality of inoculation nozzles 21 are rotatably mounted. A rack 294 is fixedly mounted on the side of the balancing motion guide 29 away from the outer frame 11, and a half gear 293 is fixedly mounted at the position where the surface of the plurality of inoculation nozzles 21 overlaps with the half gear 293.

[0054] The surface of the half gear 293 is fixedly provided with semicircular teeth, and the surface of the rack 294 is fixedly provided with teeth meshing with the half gear 293. The half gear 293 can mesh with the rack 294 and when the inoculation component 2 moves horizontally, the half gear 293 meshes with the rack 294, and the mutual meshing enables the half gear 293 to roll along the rack 294, thereby driving the inoculation nozzle 21 to rotate during the movement, thereby further realizing dynamic coverage spraying, further avoiding dead angles in spraying, and improving the uniformity of spraying.

[0055] It should be noted that the specific tooth shapes of the half gear 293 and the rack 294 can adopt any tooth shape that can be realized in the prior art. The semicircular teeth of the half gear 293 can limit the rotation angle of the inoculation nozzle 21, thereby preventing the inoculation nozzle 21 from rotating excessively during rotation and spraying.

[0056] It should be noted again that the rotation angle of the half gear 293 can be adjusted and controlled by setting the diameter and number of teeth of the half gear 293 and the gear ratio between the half gear 293 and the rack 294, thereby controlling the spraying angle of the inoculation nozzle 21.

[0057] It should be noted again that the rack 294 can also be arranged at intervals to allow the inoculation nozzle 21 to intermittently change its angle during horizontal movement. Combined with the different spray hole angles of the inoculation nozzle 21 in the initial state, it can further ensure that the inoculation nozzle 21 sprays at different angles during movement to enhance the coverage effect of dynamic spraying.

[0058] During the horizontal movement of the mobile inoculation component 2, the inoculation guide tube 22 moves along the auxiliary wheel 292. At the same time, the half gear 293 on the surface of the inoculation nozzle 21 contacts and rotates with the rack 294, so that the rotating half gear 293 drives the inoculation nozzle 21 to rotate synchronously, thereby enabling multiple inoculation nozzles 21 to change the spraying angle during movement to increase the spraying range, thereby reducing the moving stroke of the mobile inoculation component 2 during spraying and dynamically covering to avoid spraying dead angles.

[0059] At the same time, the multiple inoculation nozzles 21 in the horizontal direction can also face different angles in the initial state, so that the multiple inoculation nozzles 21 can move and spray at different angles, further avoiding the existence of spraying dead angles and improving the uniformity of spraying.

[0060] It should be noted that the embodiment of the present disclosure is more suitable for situations where the inoculation surface is uneven, so that dynamic coverage can be achieved by rotating during mobile spraying to avoid dead corners in spraying.

[0061] Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
