Description

Technical Field

[0001] The invention relates to the technical field of tree pest control devices, in particular to a backpack electric trunk injection machine. Background Art

[0002] CN116784143A discloses a micro-hole electric trunk injection machine and its use method, which has the functions of needle insertion, injection and needle withdrawal, solving the problem that the existing micro-hole manual trunk injection method usually requires multiple people to cooperate in the construction, and each injection requires constant switching of different tools required for needle insertion, injection and needle withdrawal. However, it adopts a handheld structure, which is slightly inconvenient to carry while performing the injection operation. Moreover, it is difficult to accurately control the amount of liquid medicine injected into the tree. Summary of the invention

[0003] The purpose of the present invention is to provide a backpack electric trunk injector, which is carried on the back, easy to carry and operate, and can accurately control the amount of liquid medicine injected into trees of different types and diameters.

[0004] A backpack electric trunk injection machine comprises a back plate, an injection pump and a medicine pot arranged on the back plate; the injection pump comprises a push rod, a syringe and a piston, the push rod is connected to the piston in the syringe to drive the piston to move back and forth in the syringe to achieve repeated drug suction and injection; the syringe is connected to the delivery pump through a liquid inlet check valve, and the delivery pump is connected to the medicine pot; the syringe is connected to the inner cavity of the shunt block through a liquid outlet check valve, and the inner cavity of the shunt block is connected to the injection needle for inserting into the tree trunk through a hose; the controller is electrically connected to the injection pump, the delivery pump, the liquid inlet check valve, the liquid outlet check valve and the input device respectively; the controller has a cumulative injection tree number memory for storing the cumulative number of trees that have been injected with liquid medicine and a cumulative injection amount memory for storing the cumulative injection amount;

[0005] When the injection pump sucks medicine, the inlet check valve opens, the outlet check valve closes, the delivery pump works, and the liquid in the medicine pot is pumped by the delivery pump and sucked by the injection pump. The liquid medicine enters the injection barrel from the medicine pot, through the delivery pump and the inlet check valve; when the injection pump injects medicine, the inlet check valve closes, the outlet check valve opens, and the liquid medicine in the injection barrel is discharged through the outlet check valve, the diverter block, the hose, and the injection needle.

[0006] The single injection volume discharged by the injection barrel is a, where n is a natural number; when the injection volume na of a tree is input into the controller through the input device and confirmed, the controller uses the injection volume na as the remaining injection volume; after confirming the injection volume, the injection pump starts working, and the push rod drives the piston to start reciprocating movement. After each injection by the injection pump, the value of the cumulative injection volume is increased by a, and the value after subtracting the single injection volume a from the remaining injection volume replaces the original remaining injection volume, until the remaining injection volume is 0, the injection pump stops working, and the value of the cumulative number of injected trees is increased by 1.

[0007] In the above-mentioned backpack electric trunk injection machine, the injection pump pauses between each time of sucking up medicine and before injecting medicine. During the pause time, the liquid inlet one-way valve opens, the liquid outlet one-way valve closes, the delivery pump works, and the liquid in the medicine pot continues to be pumped by the delivery pump, from the medicine pot, through the delivery pump, and the liquid inlet one-way valve into the injection barrel.

[0008] The above-mentioned backpack electric trunk injection machine has multiple hoses and injection needles, and the multiple hoses are connected in parallel to the inner cavity of the diverter block.

[0009] The above-mentioned backpack electric trunk injection machine has a plurality of buttons on the controller, including "confirm", "quick set", "start", "increase / ↑", and "decrease / ↓".

[0010] After the injection amount na of a tree is input through the input device, pressing the "Confirm" button indicates confirmation of the input value;

[0011] When the "Confirm" and "Start" buttons are pressed at the same time, the injection pump starts working;

[0012] Press the "Quick Set" button, and the controller will confirm the previous injection amount as the new injection amount, and set the new injection amount as the remaining injection amount.

[0013] In the above-mentioned backpack electric trunk injection machine, a pressure sensor is provided on the shunt block to detect the injection pressure of the liquid medicine in the inner cavity of the shunt block when the injection pump injects medicine, and the pressure sensor is electrically connected to the controller; the controller is connected to the alarm;

[0014] When the pressure sensor detects that the injection pressure of the injection pump is less than the minimum set value during one injection, the injection is deemed invalid. After the invalid injection by the injection pump, the remaining injection volume does not need to be replaced by the value after subtracting the single injection volume a, that is, the remaining injection volume remains unchanged;

[0015] When the pressure sensor detects that the injection pressure of the injection pump is greater than the maximum set value during one injection, the controller controls the alarm to sound an alarm and controls the injection pump to suspend working. After replacing the injection needle or changing the injection position of the trunk, when the "Confirm" and "Start" buttons are pressed at the same time, the injection pump continues to work.

[0016] The above-mentioned backpack electric trunk injection machine, the buttons include an "exhaust" button,

[0017] Press and hold the "Exhaust" button, the syringe pump starts to exhaust the air in the pipeline, release the "Exhaust" button, and the syringe pump stops exhausting.

[0018] The above-mentioned backpack electric trunk injector has a GPS module on the controller for recording the geographical location of the injected tree.

[0019] The above-mentioned backpack electric trunk injection machine also includes a display connected to the controller, which is used to display the remaining injection amount, the cumulative number of injected trees, the cumulative injection amount, the injection pressure, time, longitude and latitude, and altitude.

[0020] The above-mentioned backpack electric trunk injection machine has a controller equipped with a data card for recording and reading injection data. The injection data can also be transmitted to a third-party platform (such as a mobile phone, a cloud platform) via Bluetooth or the Internet.

[0021] The above-mentioned backpack electric trunk injection machine has a liquid outlet pipe at the bottom of the medicine pot connected to the delivery pump through a quick connector, and a medicine pot cover is provided at the upper end of the medicine pot.

[0022] The medicine pot of the above-mentioned backpack electric trunk injection machine can be quickly removed and replaced as a whole.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention is based on the single injection volume a discharged by the syringe at one time, and controls the injection volume injected into the tree trunk according to the number of times the push rod of the injection pump drives the piston to move back and forth, that is, the number of injections of the syringe. In order to ensure the accuracy of the injection volume injected into the tree, it is necessary to ensure that the liquid medicine can fill the inside of the syringe every time the syringe draws medicine. For this reason, the present invention uses a delivery pump to assist in pumping the liquid medicine to the syringe. In this way, the liquid medicine can fill the syringe every time the syringe draws medicine. At the same time, the stroke of the piston is certain, which ensures that the single injection volume a discharged by the syringe at one time is accurate. Therefore, the present invention can accurately control the injection volume of a tree.

[0025] 2. Easy to operate. The controller controls the number of reciprocating movements of the piston in the injection pump according to the amount of medicine to be injected into the tree. When the number is reached, the injection pump automatically stops working.

[0026] 3. The injection pump pauses between each time of sucking up medicine and before injecting it. During the pause time, the delivery pump continues to work to further ensure that the liquid medicine can fill the injection barrel, thereby ensuring the accuracy of the amount of medicine injected into the tree.

[0027] 4. Multiple injection needles can be inserted into different parts of a tree, and the tree can be injected at the same time, so that the liquid medicine is distributed more evenly on the tree body and the injection efficiency is effectively improved.

[0028] 5. The "Quick Set" button can quickly input the last input injection volume into the controller to simplify the operation.

[0029] 6. The pressure sensor detects the injection pressure in real time. If the injection pressure is too low, it means that the injection needle has not been inserted into the tree trunk. The injection is deemed invalid and the remaining injection volume remains unchanged. This can also prevent the operator from not injecting the tree with liquid medicine. If the injection pressure is too high, it means that the injection needle is inserted into the wrong position of the tree trunk or the injection needle is blocked. It is necessary to change the insertion position or replace the injection needle. After changing the injection needle or injection position, when the "Confirm" and "Start" buttons are pressed at the same time, the injection pump continues to work, and the operation is quick.

[0030] 7. Before the formal injection of the tree, press and hold the "exhaust" button, and the injection pump will start to exhaust the air in the pipeline. When the injection needle sprays out continuous liquid medicine instead of intermittent liquid medicine, it means that the gas inside the injection cylinder, diverter block, hose, injection needle, etc. has been completely exhausted. After this exhaust process, the accuracy of the subsequent injection of liquid medicine to the tree can be improved.

[0031] 8. GPS module is used to record the operation time, longitude and latitude, altitude and other geographical locations of the injected trees, and determine the distribution of the injected trees.

[0032] 9. The display shows the remaining injection volume, the cumulative number of injections, the cumulative injection volume, the injection pressure, the battery power and other data. The battery is used to power the entire machine, such as the push rod motor that drives the push rod in the injection pump, the motor that drives the delivery pump in the delivery pump, and the controller.

[0033] 10. The liquid outlet pipe at the bottom of the medicine pot is connected to the delivery pump through a quick connector, which is convenient for replacing the medicine pot. You can add liquid medicine into the medicine pot by opening the medicine pot cover.

[0034] 11. The medicine pot can be quickly removed and replaced as a whole, making it convenient to switch and inject different types of medicines.

[0035] 12. The controller controls and monitors the operation of the injection machine in real time, ensuring the reliable operation of the injection machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The controller is electrically connected to the PCB, and the PCB is electrically connected to the injection pump 2, the micro switch 7, the delivery pump 8, the liquid inlet check valve 10, the liquid outlet check valve 11, etc. The control box 3 has a display screen and a plurality of buttons electrically connected to the controller, and the buttons include "confirm", "quick set", "start", "exhaust", "reset", "pause", "increase / ↑", "decrease / ↓" and other buttons.

[0045] The injection pump 2 includes a push rod motor 21 connected to the back plate, a push rod 22 that moves up and down driven by the push rod motor, a syringe 23, a piston, etc. A touch block 25 is fixed on the push rod 22. The touch block 25 touches the micro switch 7 once each time it reciprocates driven by the push rod 22, and the micro switch feeds back a signal to the controller through the PCB board 6 to achieve counting.

[0046] The push rod 22 is connected to the piston in the syringe 23 to drive the piston to move back and forth in the syringe 23 to achieve repeated drug suction and injection; the syringe 23 is connected to the delivery pump 8 through the liquid inlet check valve 10, and the delivery pump 8 is connected to the liquid outlet pipe at the bottom of the medicine pot 4 through the quick connector 14, etc.; the syringe is connected to the inner cavity of the diverter block 12 through the liquid outlet check valve 11, and the inner cavity of the diverter block 12 is connected to the three injection needles 16 for inserting into the tree trunk through three hoses 18 and quick connectors (not shown); the controller has a cumulative injection tree number memory for storing the cumulative number of trees that have been injected with liquid medicine and a cumulative injection amount memory for storing the cumulative injection amount;

[0047] When the injection pump draws medicine, the inlet one-way valve 10 opens, the outlet one-way valve 11 closes, the delivery pump 8 works, and the liquid in the medicine pot 4 is pumped by the delivery pump 8 and sucked by the injection pump, and the liquid enters the injection barrel 23 from the medicine pot 4, through the quick connector 14, the delivery pump 8, and the inlet one-way valve 10; when the injection pump injects medicine, the inlet one-way valve 10 is closed, the outlet one-way valve 11 is opened, and the liquid in the injection barrel 23 is discharged (injected into the tree trunk) through the outlet one-way valve 11, the diverter block 12, the hose 18, the quick connector (not shown), and the injection needle 16; the injection pump pauses between each time of drawing medicine and injecting medicine. During the pause time, the inlet one-way valve 10 opens, the outlet one-way valve 11 closes, the delivery pump 8 works, and the liquid in the medicine pot 4 continues to be pumped by the delivery pump 8, and enters the injection barrel 23 from the medicine pot 4 through the quick connector 14, the delivery pump 8, and the inlet one-way valve 10.

[0048] The single injection amount discharged by the syringe 23 is a, and n is a natural number. In the standby state, each time the "increase / ↑" button is pressed, the remaining injection amount increases by a, and each time the "decrease / ↓" button is pressed, the remaining injection amount decreases by a; pressing the "confirm" button indicates confirmation that the input remaining injection amount is the injection amount for one tree. When the injection amount na of one tree is input to the controller through the input device (control box) and confirmed, the controller uses the injection amount na as the remaining injection amount; after confirming the injection amount, when the injection pump starts working, the push rod drives the piston to start reciprocating movement. After each injection of the injection pump, the cumulative injection amount is increased by a, and the remaining injection amount minus the single injection amount a replaces the original remaining injection amount, until the remaining injection amount is 0, the injection pump stops working, and then the cumulative injection number of trees is increased by 1.

[0049] After the injection amount na of a tree is input through the input device, pressing the "Confirm" button indicates confirmation of the input value;

[0050] When the "Confirm" and "Start" buttons are pressed at the same time, the injection pump starts working;

[0051] Press the "Quick Set" button, and the controller will confirm the previous injection amount as the new injection amount, and set the new injection amount as the remaining injection amount.

[0052] The shunt block 12 is provided with a pressure sensor 13 for detecting the injection pressure of the liquid medicine in the inner cavity of the shunt block 12 when the injection pump injects medicine. The pressure sensor 13 is electrically connected to the controller through a PCB board; the controller is connected to the alarm;

[0053] When the pressure sensor 13 detects that the injection pressure of the injection pump is less than the minimum set value during one injection, the injection is deemed invalid. After the invalid injection by the injection pump, the remaining injection volume does not need to be replaced by the value after subtracting the single injection volume a, that is, the remaining injection volume remains unchanged.

[0054] When the pressure sensor 13 detects that the injection pressure of the injection pump is greater than the maximum set value during one injection, the controller controls the alarm to sound an alarm and controls the injection pump to suspend operation. After replacing the injection needle 16 or changing the injection position of the trunk, when the "Confirm" and "Start" buttons are pressed at the same time, the injection pump continues to work.

[0055] Press and hold the "Exhaust" button, the injection pump starts to exhaust the air in the pipeline, release the "Exhaust" button, and the injection pump stops working.

[0056] The controller is equipped with a GPS module for recording the operation time and geographic location of the injected trees.

[0057] The display is used to display the remaining injection amount, the cumulative number of injected trees, the cumulative injection amount, the injection pressure, time, longitude and latitude, and altitude.

[0058] Operation process:

[0059] 1. Unscrew the medicine pot cover, add enough medicine liquid and tighten the cover. Turn on the controller power switch and the main power switch.

[0060] 2. Connect the quick connector connected to the hose to the injection needle, and long press the "Exhaust" button to exhaust the air in the equipment.

After the quick connector is connected to one or more injection needles inserted into the tree trunk, press the confirmation and start buttons at the same time, and the equipment starts injecting medicine.

[0062] 4. After pressing the confirmation and start buttons, the push rod and piston retract to absorb the medicine liquid, and the medicine liquid flows out of the medicine pot, passes through the quick connector 14, the delivery pump (to assist the piston in absorbing the medicine to prevent the negative pressure in the syringe from being too small and the medicine liquid cannot be filled), the liquid inlet one-way valve, and then flows into the syringe; the push rod and piston extend, and the medicine liquid in the syringe is pushed into the cavity of the diverter block through the liquid outlet one-way valve, and finally flows to the injection needle through the hose, realizing the process of injecting the medicine liquid into the tree trunk.

[0063] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from all points of view, and the scope of the present invention is defined by the appended claims and their equivalents.
