[0039] refer to Figures 1 to 6 An automatic device for adding bacteria to organic fertilizer and a control method thereof according to an embodiment of the present invention are described.

[0040] like Figures 1 to 6 As shown, the automatic adding device for adding bacteria to organic fertilizer according to the embodiment of the present invention comprises: a frame 100; a bacteria liquid bottle 200, which is detachably mounted on the frame 100, and the bacteria liquid bottle 200 is loaded with a bacteria solution; a disinfectant bottle 300, which is arranged on the frame 100, and the disinfectant bottle 300 is loaded with a disinfectant solution; a peristaltic pump 400, which is arranged on the frame 100, and one end of the peristaltic pump 400 is connected to the bacteria liquid bottle 200 through a first pipeline 210, and a three-way reversing valve 500, which comprises a first reversing valve 500, a second reversing valve 500, and a third reversing valve 500. An interface 510, a second interface 520, a third interface 530 and a valve core 540, the other end of the peristaltic pump 400 is connected to the first interface 510, the second interface 520 is connected to a discharge pipeline 550, the discharge pipeline 550 is used to add bacterial solution to the organic fertilizer, the third interface 530 is connected to the disinfectant bottle 300 through the second pipeline 310, and the valve core 540 rotates to connect the first interface 510 with the second interface 520, or to connect the first interface 510 with the third interface 530; a controller, the controller is electrically connected to the peristaltic pump 400 and the three-way reversing valve 500 respectively.

[0041] like Figures 1 to 6As shown, the bacterial liquid bottle 200 is connected to the peristaltic pump 400 through the first pipeline 210, the other end of the peristaltic pump 400 is connected to the first interface 510 of the three-way reversing valve 500, and the second interface 520 of the three-way reversing valve 500 is connected to the discharge pipeline 550. Therefore, when the valve core 540 is rotated to connect the first interface 510 with the second interface 520, the bacterial liquid bottle 200 is connected to the discharge pipeline 550 through the first pipeline 210 and the peristaltic pump 400. The peristaltic pump 400 operates under the control of the controller to add the bacterial solution in the bacterial liquid bottle 200 to the organic fertilizer in a timely and quantitative manner, thereby improving the degree of automation of the organic bacterial addition process. The controller controls the delivery of the bacterial solution, so that the delivery time and delivery amount of the bacterial solution are more accurate, thereby improving the quality of the finished organic fertilizer.

[0042] The third interface 530 of the three-way reversing valve 500 is connected to the disinfectant bottle 300 through the second pipeline 310. When the valve core 540 rotates to connect the first interface 510 with the third interface 530, the disinfectant bottle 300 is connected to the bacterial liquid bottle 200 through the second pipeline 310, the peristaltic pump 400 and the first pipeline 210. Since the peristaltic pump 400 can transport liquid in both directions, the controller controls the peristaltic pump 400 to operate in the reverse direction to transfer the disinfectant in the disinfectant bottle 300. The liquid is transported to the culture liquid bottle 200 through the second pipeline 310, the peristaltic pump 400 and the first pipeline 210. During this process, the disinfectant solution passes through the first pipeline 210, the peristaltic pump 400 and the three-way reversing valve 500 through which the culture liquid passes during the delivery process. Therefore, the first pipeline 210, the peristaltic pump 400 and the three-way reversing valve 500 are all disinfected by the disinfectant solution. The disinfectant solution is finally transported to the culture liquid bottle 200 to disinfect the culture liquid bottle 200.

[0043] After disinfection is completed, the valve core 540 of the three-way reversing valve 500 remains stationary, and the first interface 510 is still connected to the third interface 530, that is, the disinfectant bottle 300 is connected to the bacterial seed liquid bottle 200 through the second pipeline 310, the peristaltic pump 400 and the first pipeline 210. The controller controls the peristaltic pump 400 to operate in the forward direction to transport the disinfectant solution in the bacterial seed liquid bottle 200 back to the disinfectant bottle 300. The operator removes the empty bacterial seed liquid bottle 200 and replaces it with a new one to add the next round of bacterial seed solution.

[0044] Thus, through the reversal of the valve core 540 of the three-way reversing valve 500 and the reverse operation of the peristaltic pump 400, the first pipeline 210, the peristaltic pump 400 and the three-way valve through which the bacterial solution passes during the delivery process are all disinfected, and the operator only needs to regularly replace the drainage pipeline 550 disposed outside the rack 100 to ensure that the entire device is not contaminated by the bacterial solution. There is no need to disassemble the equipment for cleaning after each bacterial addition, which saves a lot of labor costs, effectively prevents bacterial leakage from polluting the environment, and improves the degree of automation of bacterial solution addition.

[0045] In some specific implementations of the present invention, a pneumatic actuator and a valve feedback device are provided on the three-way reversing valve 500. The pneumatic actuator is connected to the valve core 540 of the three-way reversing valve 500, and is used to drive the valve core 540 to rotate. The valve feedback device is connected to the pneumatic actuator, and the valve feedback device is electrically connected to the controller. The valve feedback device is used to display the state of the valve core 540 and feed back the state information of the valve core 540 to the controller. The controller controls the forward and reverse operation of the peristaltic pump 400 according to the state of the valve core 540. Therefore, the operation of the peristaltic pump 400 is based on the actual connection of each interface of the three-way reversing valve 500. The setting of the valve feedback device makes the controller more accurate in controlling the operation of the peristaltic pump 400, and can display the state of the valve core 540 in real time, which is convenient for operators to inspect and maintain the device.

[0046] like Figure 2 and Figure 3 As shown, the automatic organic fertilizer strain adding device also includes an identification identifier 600, which is arranged on the frame 100, and the identification identifier 600 is arranged on the right side of the strain liquid bottle 200, and the identification identifier 600 is arranged toward the strain liquid bottle 200. Whenever the operator replaces the strain liquid bottle 200, the identification identifier 600 will read the identification on the body of the strain liquid bottle 200, thereby confirming the information of the strain solution, avoiding the reuse of the strain liquid bottle 200, and facilitating the traceability of the added strain solution.

[0047] In some specific embodiments of the present invention, the automatic organic fertilizer strain adding device includes a cannula assembly 700, which is movably arranged on the frame 100 up and down. The cannula assembly 700 is connected to the first pipeline 210 and the second pipeline 310 respectively. The cannula assembly 700 moves up and down to separate and connect the first pipeline 210 and the second pipeline 310 with the strain liquid bottle 200 and the disinfectant bottle 300 respectively.

[0048] like Figures 1 to 3As shown, the cannula assembly 700 includes: a movable plate 710, which is movably arranged on the frame 100 up and down; a driving member 720, which is connected to the movable plate 710, and is used to drive the movable plate 710 to move up and down, and the driving member 720 is electrically connected to the controller; a first barbed tube 730, which is arranged on the movable plate 710 along the up and down direction, the first barbed tube 730 corresponds to the bottle mouth of the bacterial liquid bottle 200, and the first barbed tube 730 is connected to the first pipeline 210; a second barbed tube 740, which is arranged on the movable plate 710 along the up and down direction, the second barbed tube 740 corresponds to the bottle mouth of the disinfectant bottle 300, and the second barbed tube 740 is connected to the second pipeline 310.

[0049] The mouths of the bacterial liquid bottle 200 and the disinfectant bottle 300 are both set upward, the first barbed tube 730 and the second barbed tube 740 are both set in the up-down direction, the first barbed tube 730 is aligned with the second mouth of the bacterial liquid bottle 200, and the second barbed tube 740 is aligned with the mouth of the disinfectant bottle 300, the first barbed tube 730 and the second barbed tube 740 are both set on the movable plate 710, the movable plate 710 is connected to the driving member 720, the driving member 720 is a screw nut mechanism driven by a motor, the motor drives the movable plate 710 to move up and down, and the movable plate 710 is positioned by two positioning columns 770 set in the up-down direction. The driving member 720 drives the movable plate 710 to move up and down, and can move the first barbed tube 730 and the second barbed tube 740 up and down. When the first barbed tube 730 moves upward, the first barbed tube 730 is pulled out of the bacterial seed liquid bottle 200; when the first barbed tube 730 moves downward, the first barbed tube 730 is inserted into the bacterial seed liquid bottle 200, and the first barbed tube 730 is connected to the first pipeline 210.

[0050] When the culture liquid bottle 200 needs to be replaced, the driving member 720 drives the movable plate 710 to move upward, and the first thorn tube 730 is separated from the old culture liquid bottle 200, so that the operator can disassemble the old culture liquid bottle 200 and install a new culture liquid bottle 200. After the installation is completed, the driving member 720 drives the movable plate 710 to move downward, and the first thorn tube 730 is inserted into the new culture liquid bottle 200. The first pipeline 210 is connected with the new culture liquid bottle 200 to add the next round of culture solution.

[0051] Therefore, there is no need to manually connect the bacterial liquid bottle 200 to the circuit or remove it from the circuit. The operator only needs to take out the old bacterial liquid bottle 200 and install the new bacterial liquid bottle 200 in place. The automatic adding device for organic fertilizer bacterial strains can automatically connect the bacterial liquid bottle 200 to the circuit or remove it from the circuit, further improving the automation of the device, improving the efficiency of bacterial strain addition, and reducing the risk of bacterial strain leakage caused by improper human operation.

[0052] Since a small amount of liquid may remain in the first thorn tube 730 and the second thorn tube 740, when the first thorn tube 730 and the second thorn tube 740 move upward and separate from the bacterial liquid bottle 200 and the disinfectant bottle 300, the liquid remaining in the first thorn tube 730 and the second thorn tube 740 is at risk of dripping, causing environmental pollution. Therefore, the cannula assembly 700 also includes an anti-drip assembly, which is connected to the first thorn tube 730 and the second thorn tube 740 respectively. When the first thorn tube 730 and the second thorn tube 740 move upward and separate from the bacterial liquid bottle 200 and the disinfectant bottle 300, the anti-drip assembly sucks the solution in the first thorn tube 730 and the second thorn tube 740.

[0053] like Figure 2 and Figure 3 As shown, the anti-drip assembly includes a first plunger pump 750 and a second plunger pump 760, and the first plunger pump 750 and the second plunger pump 760 are connected to the first thorn tube 730 and the second thorn tube 740 respectively. The first plunger pump 750 includes a first pump body 751 and a first pump core 752. The first pump body 751 is arranged on the movable plate 710, and a first pump cavity is provided in the first pump body 751. The first pump core 752 is arranged in the first pump cavity, and the first pump cavity is communicated with the first thorn tube 730. The first pump core 752 is fixed on the frame 100, and the movable plate 710 drives the first pump body 751 to move up and down, so that the first pump cavity moves up and down relative to the first pump core 752. The structure of the second plunger pump 760 is similar to that of the first plunger pump 750, and will not be repeated.

[0054] When the driving member 720 drives the movable plate 710 to move upward to extract the first thorn tube 730 from the bacterial liquid bottle 200, the movable plate 710 simultaneously drives the first pump body 751 to move upward, and at this time, the first pump core 752 moves downward relative to the first pump chamber, the volume of the first pump chamber increases, and the pressure decreases. Since the first pump chamber is connected to the first thorn tube 730, the residual liquid in the first thorn tube 730 will be sucked into the first pump chamber to prevent the liquid in the first thorn tube 730 from dripping downward and causing pollution. The action of the first plunger pump 750 sucking the residual liquid in the first thorn tube 730 is driven by the movable plate 710, and no additional power source is required, and no additional detection of the movement state of the first thorn tube 730 is required. As long as the first thorn tube 730 moves upward, the first plunger pump 750 will operate synchronously to complete the suction action, so that the structure of the anti-drip assembly is simple and the anti-drip function is reliable.

[0055] In some embodiments of the present invention, a control method for an automatic adding device for organic fertilizer bacteria includes:

[0056] Step 1: The controller controls the valve core 540 of the three-way reversing valve 500 to rotate, so that the first interface 510 is connected to the second interface 520. At this time, the bacterial solution bottle 200 is connected to the drainage pipeline 550. The controller controls the peristaltic pump 400 to operate in the forward direction, and the bacterial solution is added to the organic fertilizer in a timely and quantitative manner;

[0057] Step 2: The controller controls the valve core 540 of the three-way valve to rotate, so that the first interface 510 is connected to the third interface 530. At this time, the bacterial liquid bottle 200 and the disinfectant bottle 300 are connected. The controller controls the peristaltic pump 400 to operate in the reverse direction to transport the disinfectant solution in the disinfectant bottle 300 to the bacterial liquid bottle 200 to disinfect the bacterial liquid bottle 200. The disinfectant solution flows through and disinfects the first pipeline 210, the second pipeline 310, the peristaltic pump 400 and the three-way reversing valve 500;

[0058] Step 3: Keep the first interface 510 connected to the third interface 530, the controller controls the peristaltic pump 400 to operate in the forward direction, recover the disinfectant solution in the culture liquid bottle 200 into the disinfectant bottle 300, the operator removes the empty culture liquid bottle 200, and installs a new culture liquid bottle 200 filled with culture solution on the rack 100.

[0059] In step 3, the controller controls the peristaltic pump 400 to operate in the forward direction, and after the disinfectant solution in the culture liquid bottle 200 is recovered into the disinfectant bottle 300, the driving member 720 drives the movable plate 710 to move upward, so that the first puncture tube 730 moves upward and separates from the culture liquid bottle 200. After the operator replaces the new culture liquid bottle 200, the driving member 720 drives the movable plate 710 to move downward, and the first puncture tube 730 pierces the new culture liquid bottle 200.

[0060] In some specific embodiments of the present invention, the identification identifier 600 is connected to the controller. When the identification identifier 600 detects that a new culture liquid bottle 200 is installed on the frame 100, the driving member 720 drives the movable plate 710 to move downward, so that the first piercing tube 730 penetrates into the new culture liquid bottle 200 to add the next round of culture solution.

[0061] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
