Description

Technical Field

[0002] Beneficial bacteria in the soil refer to microorganisms that are helpful to plant growth, such as nitrogen-fixing bacteria and phosphate-solubilizing bacteria. They can improve soil structure and increase the availability of nutrients. In order to better understand soil microbial communities, optimize soil management, and increase crop yields and health, it is often necessary to detect beneficial bacteria in the soil.

[0003] A soil beneficial bacteria detection device and system in the prior art (publication number: CN117720988A) stabilizes the device during use by inserting an anti-slip cone into the soil, and at the same time inserts the detection probes at the front and rear ends of the bottom of the detection rod into the soil so that the detection probes are in contact with the soil, thereby detecting the beneficial bacteria content in the soil. However, in order to improve the accuracy of the detection, it is often necessary to change multiple positions for detection.

[0013] A method for using a soil beneficial bacteria detection device includes the following steps:

[0014] Step 1: After the device reaches the detection position, push and place the screw rod in a vertical state through the handle, and rotate the screw rod to make it threadedly connected with the connecting block. As the screw rod rotates, drive the limiting rod to extend downward and insert into the soil through the connecting piece. At the same time, drive the braking mechanism to perform double limit on the device. The connecting piece also drives the lifting block to descend, so that the detection probe extends out from the bottom of the cleaning tank and also inserts into the soil. Start the detector body to work through the control panel, and then the beneficial bacteria in the soil can be detected. The detection data is stored in the control panel.

[0015] Step 2: After collecting a set of data, set the three-way solenoid valve through the control panel to connect the piston cylinder with the water extraction pipe, so that the equipment can pump out the water in the water tank during the movement process. When the equipment moves to the next target position to the halfway position of the stroke, switch the three-way solenoid valve to connect the piston cylinder with the air;

[0016] Step 3: Then transfer the detection position. During the transfer process, the handle is used to drive the screw rod to rotate in the opposite direction, thereby raising the height of the limit rod and the detection probe so that they are both out of the soil, releasing the limit on the equipment, lifting the screw rod until it is disconnected from the threaded connection with the adapter block, and then pulling the screw rod to make it swing in the opposite direction away from the equipment through the movable part, so that the operator can pull the equipment for transfer;

[0017] Step 4: During the transfer process, the rotation of the wheel can drive the crankshaft to rotate, and then the transmission mechanism can drive the two cleaning brushes in the cleaning box to rotate and clean the detection probe. At the same time, the crankshaft intermittently drives the piston block in the piston cylinder through the first push-pull rod, the second push-pull rod and the slider to extract part of the water in the water tank and pump it into the water spray box, and then spray it on the surface of the detection probe and the cleaning brush to improve the cleaning effect. When the three-way solenoid valve is converted to connect with the air, the piston cylinder can pump air to the surface of the detection probe and the cleaning brush to accelerate its drying, so that the detection probe can remain clean for the next round of detection, thereby improving the accuracy of equipment detection.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] By setting a bottom frame with universal wheels and wheels, the detector body can be driven to easily change the detection position, and the height of the detection rod and the detection probe can be adjusted through the adjustment mechanism, so that the detection probe can be deeply immersed in the soil during detection, and at the same time, the limit rod and the brake mechanism can be driven to limit and fix the equipment, thereby improving the stability of the equipment during the detection process. When the equipment needs to change the detection position, the height of the detection probe can be raised to make it leave the soil, and the limit of the equipment can be released at the same time, and then the equipment can be pulled through the adjustment mechanism for transfer, thereby improving the flexibility of equipment transfer;

[0020] By setting up a cleaning box, during the equipment transfer process, the detection probe is lifted into the cleaning box, and the rotation of the wheel drives the crankshaft to rotate, and then through two transmission mechanisms, the two cleaning brushes in the cleaning box can be driven to clean the detection probe. At the same time, the rotation of the crankshaft can drive the piston cylinder to pump the water in the water tank into the water spray box, and then spray it on the surface of the detection probe and the cleaning brush, further improving the cleaning effect of the equipment on the detection probe, so that the detection probe can remain clean for the next round of detection, thereby improving the accuracy of equipment detection.

A push-pull rod 40 drives the piston block 604 in the piston cylinder 6 to slide up and down, so that water (or air) can be pumped intermittently into the water spray box 36, thereby assisting the cleaning brush 35 to clean the detection probe 22. The pumped air can accelerate the drying of the detection probe 22 and the cleaning brush 35 to prevent the cleaning water from affecting the accuracy of the detection data. The three-way solenoid valve 10 and the detector body 14 are both controlled by the control panel 8, and the battery 24 supplies power to the three-way solenoid valve 10, the detector body 14 and the control panel 8.

[0042] A method for using a soil beneficial bacteria detection device comprises the following steps:

[0043] S1: After the equipment reaches the detection position, the handle 17 is used to push the screw 16 into a vertical state, and the screw 16 is rotated to be threadedly connected with the adapter block 18. As the screw 16 rotates, the limit rod 20 is driven to extend downward and insert into the soil through the adapter 37, and at the same time, the brake mechanism is driven to double limit the equipment. The adapter 37 simultaneously drives the lifting block 15 to descend, so that the detection probe 22 extends from the bottom of the cleaning box 21 and is also inserted into the soil. The detector body 14 is started to work through the control panel 8, and the beneficial bacteria in the soil can be detected, and the detection data is stored in the control panel 8;

[0044] S2: After collecting a set of data, the three-way solenoid valve 10 is set through the control panel 8 to connect the piston cylinder 6 with the water extraction pipe 11, so that the water in the water tank 7 can be extracted during the movement of the device. When the device as a whole moves to the next target position to the halfway position of the stroke, the three-way solenoid valve 10 is switched to connect the piston cylinder 6 with the air;

[0045] S3: Then the detection position is transferred. During the transfer process, the handle 17 is used to drive the screw rod 16 to rotate in the opposite direction, thereby raising the height of the limit rod 20 and the detection probe 22 so that they are both out of the soil, releasing the limit on the equipment, and lifting the screw rod 16 to be detached from the threaded connection with the adapter block 18. Then, the screw rod 16 is pulled to swing away from the equipment through the movable part 39, so that the operator can pull the equipment for transfer;

[0046] S4: During the transfer process, the rotation of the wheel 3 drives the crankshaft 32 to rotate, and then the transmission mechanism drives the two cleaning brushes 35 in the cleaning box 21 to rotate and clean the detection probe 22. At the same time, the crankshaft 32 intermittently drives the piston block 604 in the piston cylinder 6 through the first push-pull rod 40, the second push-pull rod 42 and the slider 41 to extract part of the water in the water tank 7 and pump it into the water spray box 36, and then spray it on the surface of the detection probe 22 and the cleaning brush 35 to improve the cleaning effect. When the three-way solenoid valve 10 is converted to be connected to the air, the piston cylinder 6 can pump air to the surface of the detection probe 22 and the cleaning brush 35 to accelerate its drying, so that the detection probe 22 can be kept clean for the next round of detection, thereby improving the accuracy of equipment detection.

2. A method for using a soil beneficial bacteria detection device, characterized in that: The soil beneficial bacteria detection device according to claim 1 comprises the following steps: S1: After the device reaches the detection position, the handle (17) is used to push the screw rod (16) into a vertical state, and the screw rod (16) is rotated to be threadedly connected with the adapter block (18). As the screw rod (16) rotates, the limit rod (20) is driven to extend downward and insert into the soil through the adapter (37), and at the same time, the brake mechanism is driven to double-limit the device. The adapter (37) simultaneously drives the lifting block (15) to descend, so that the detection probe (22) extends from the bottom of the cleaning box (21) and also inserts into the soil. The detector body (14) is started to work through the control panel (8), and the beneficial bacteria in the soil can be detected. The detection data is stored in the control panel (8); S2: After collecting a set of data, the three-way solenoid valve (10) is set through the control panel (8) to connect the piston cylinder (6) with the water extraction pipe (11), so that the water in the water tank (7) can be extracted during the movement of the device. When the device as a whole moves to the next target position to the halfway position of the stroke, the three-way solenoid valve (10) is switched to connect the piston cylinder (6) with the air; S3: Then the detection position is transferred. During the transfer process, the handle (17) is used to drive the screw rod (16) to rotate in the opposite direction, thereby raising the height of the limit rod (20) and the detection probe (22) so that they are both away from the soil, releasing the limit on the equipment, and lifting the screw rod (16) until it is disconnected from the threaded connection with the adapter block (18). Then, the screw rod (16) is pulled to swing away from the equipment through the movable part (39), so that the operator can pull the equipment to transfer it; S4: Transfer process: As the wheel (3) rotates, the crankshaft (32) can be driven to rotate, and then the two cleaning brushes (35) in the cleaning box (21) can be driven to rotate through the transmission mechanism to clean the detection probe (22). At the same time, the crankshaft (32) intermittently drives the piston block (604) in the piston cylinder (6) through the first push-pull rod (40), the second push-pull rod (42) and the slider (41) to extract part of the water in the water tank (7) and pump it into the water spray box (36), and then spray it on the surface of the detection probe (22) and the cleaning brush (35), thereby improving the cleaning effect. When the three-way solenoid valve (10) is switched to be connected to the air, the piston cylinder (6) can pump air to the surface of the detection probe (22) and the cleaning brush (35) to accelerate their drying, so that the detection probe (22) is automatically cleaned before each detection.
