A plant root growth promoting bacteria injection device

Abstract

This utility model discloses a plant root growth-promoting bacteria injection device, relating to the field of plant root growth-promoting bacteria injection technology. The utility model includes a tube body, a soil-expanding component, and an air-jet anti-clogging component. The bottom of the tube body is connected to an injection head, and a piston is installed inside the tube body. The top of the piston is connected to a pressure tube, the top of which extends to the outside of the tube body. The soil-expanding component includes a control shell, the front of which is fixedly connected to the tube body. Through the soil-expanding component, during the insertion of the device into the soil, an adjusting mechanism controls the movement of the connecting plate, causing the soil-expanding shell to expand outwards, pushing aside the soil around the injection head to form a gap. This prevents soil particles from being squeezed back into the tube cavity and forming hard blockages, thereby reducing the risk of obstructed bacterial liquid discharge during injection. Frequent manual unblocking is unnecessary, improving work efficiency and reducing the possibility of root damage. When not in use, the soil-expanding shell remains closed to protect the injection head.

Description

Technical Field

[0001] This utility model belongs to the field of plant root growth-promoting bacteria injection technology, and in particular relates to a plant root growth-promoting bacteria injection device. Background Technology

[0002] Plant root growth-promoting bacteria are a class of microorganisms that colonize around or inside plant roots and promote the growth and development of plant roots directly or indirectly. Their mechanisms of action include secreting plant hormones, dissolving insoluble nutrients in the soil, producing siderophores or organic acids to improve the rhizosphere environment, and inhibiting the proliferation of pathogenic microorganisms. They are widely used in agricultural production, ecological restoration, and soil health maintenance. In the process of using plant root growth-promoting bacteria, root irrigation or drip irrigation is usually used to deliver the plant root growth-promoting bacteria to the vicinity of the plant roots.

[0003] Existing bacterial injection devices use a hollow needle design to directly pierce the soil. They mainly consist of an infusion chamber, a piston, and an injection needle. When the needle pierces the compacted soil, soil particles are squeezed back into the cavity through the opening at the end of the needle, forming hard blockages. This obstructs the discharge of bacterial solution during injection, requiring the user to manually unblock the blockage multiple times. This reduces work efficiency and increases the risk of root damage, making them unsuitable for use.

[0004] To address these issues, we provide a plant root growth-promoting bacteria injection device. Utility Model Content

[0005] The purpose of this invention is to provide a plant root growth-promoting bacteria injection device. By combining the soil expansion component and the air jet anti-clogging component, it solves the problem in the prior art where soil particles easily clog the injection head during the injection of growth-promoting bacteria, preventing the growth-promoting bacteria from being discharged normally and requiring frequent manual unclogging by the user.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a plant root growth-promoting bacteria injection device, comprising a tube body, a soil expansion component, and an air jet anti-clogging component. The bottom of the tube body is connected to an injection head, and a piston is installed inside the tube body. A pressure tube is connected to the top of the piston, and the top of the pressure tube extends to the outside of the tube body. The soil expansion component includes a control shell, the front of which is fixedly connected to the tube body. An adjustment mechanism is fixedly connected to the top of the inner cavity of the control shell. Connecting plates are fixedly connected to both sides of the adjustment mechanism, penetrating the control shell. Soil expansion shells are fixedly connected to opposite sides of the two connecting plates. The air jet anti-clogging component includes an air chamber, the front of which is fixedly connected to the tube body. An electric actuator is fixedly connected to the top of the inner cavity of the air chamber, and a pressure plate is fixedly connected to the bottom of the output end of the electric actuator. The bottom of the air chamber is connected to the tube body via an exhaust pipe, and an air inlet pipe is connected to the left side of the air chamber. One-way valves are installed on the surfaces of both the air inlet and exhaust pipes.

[0008] The present invention is further configured such that the adjustment mechanism includes a motor, the top of the motor is fixedly connected to the inner wall of the control shell, and screws are fixedly connected to both sides of the output end of the motor. The screws are threaded with telescopic rods, and the opposite sides of the two telescopic rods penetrate the control shell and are fixedly connected to the connecting plate. The motor can control the screws to rotate, and the screws can control the telescopic rods to move left and right reciprocally, for controlling the position of the connecting plate and the expansion shell.

[0009] The present invention is further configured such that a limiting shell is fixedly connected to the bottom of the control shell, and limiting rods are provided on both sides of the inner cavity of the limiting shell. The opposite sides of the two limiting rods penetrate the limiting shell and are fixedly connected to the connecting plate. The limiting shell and the limiting rods can limit the two connecting plates, so that they can move smoothly left and right.

[0010] The present invention is further configured such that a sliding rod is fixedly connected to the bottom between the two sides of the inner cavity of the control shell, and a sliding sleeve is slidably connected to both sides of the surface of the sliding rod. The top of the sliding sleeve is fixedly connected to the telescopic rod. The sliding rod and the sliding sleeve can improve the stability of the telescopic rod during movement and prevent it from rotating during movement.

[0011] The present invention is further configured such that a sealing plug is threadedly connected to the top of the pressure tube, and a handle is fixedly connected to the top of the surface of the pressure tube. The sealing plug can seal the top of the pressure tube to prevent the probiotic solution inside the tube from being discharged from its top when the pressure tube is pushed, and the handle makes it easier for the user to push the pressure tube.

[0012] The present invention is further provided that handles are fixedly connected to both sides of the tube body, and a liquid level observation window is provided on the front surface of the tube body. The handles facilitate the user to control the position of the tube body, and the liquid level observation window allows the user to easily observe the remaining amount of the growth-promoting bacteria solution.

[0013] The present invention is further configured such that the surface of the air chamber is fixedly connected to the tube body by a mounting bracket, and an elastic ring is fitted on the surface of the expansion shell. The mounting bracket is used to improve the stability of the connection between the air chamber and the tube body, and the elastic ring can limit the two expansion shells to prevent the injection head from being exposed when not in use.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a soil expansion component. During the insertion of the device into the soil, the adjustment mechanism controls the movement of the connecting plate, causing the soil expansion shell to expand outward, pushing away the soil around the injection head to form a gap. This prevents soil particles from being squeezed back into the tube cavity and forming hard blockages, thereby reducing the risk of obstruction of bacterial liquid discharge during injection. It eliminates the need for frequent manual unblocking, improves work efficiency, and reduces the possibility of root damage. When not in use, the soil expansion shell remains closed to protect the injection head.

[0016] 2. This utility model uses an air jet anti-clogging component. When the injection head is blocked, the electric push rod pushes the pressure plate down in the air chamber. Compressed air is delivered to the tube body and injection head through the exhaust pipe controlled by the one-way valve. The airflow impact force pushes out the blocking soil particles, quickly clearing the injection head, avoiding manual intervention, ensuring smooth discharge of bacterial liquid, and improving injection continuity.

[0028] Example 2

[0029] Please see Figure 1-5 Based on Embodiment 1, the adjustment mechanism 52 includes a motor 521. The top of the motor 521 is fixedly connected to the inner wall of the control housing 51. Screws 522 are fixedly connected to both sides of the output end of the motor 521. Telescopic rods 523 are threaded onto the surface of the screws 522.

[0030] Specifically: Motor 521 controls the rotation of screw 522, screw 522 controls the reciprocating movement of telescopic rod 523, used to control the position of connecting plate 53 and expansion shell 54; limiting shell 7 and limiting rod 8 limit the two connecting plates 53, allowing them to move smoothly left and right; sliding rod and sliding sleeve improve the stability of telescopic rod 523 during movement, preventing it from rotating during movement; sealing plug seals the top of pressure tube 4, preventing the probiotic solution inside tube body 1 from being discharged from its top when pressure tube 4 is pushed; handle facilitates the user to push pressure tube 4; handle facilitates the user to control the position of tube body 1; liquid level observation window allows the user to easily observe the remaining amount of probiotic solution; mounting bracket improves the stability of the connection between air chamber 61 and tube body 1; elastic ring limits the two expansion shells 54, preventing the injection head 2 from being exposed when not in use.

[0031] The working principle of this utility model is as follows: The user holds the handles on both sides of the tube body 1, positions it near the soil around the plant roots, inserts the soil expansion shell 54 into the soil near the plant roots, then turns on the motor 521. The motor 521 drives the screw 522 to rotate, and the screw 522 drives the telescopic rod 523 to move outward. The telescopic rod 523 pushes the soil expansion shell 54 to expand to both sides through the connecting plate 53. The soil expansion shell 54 pushes open the compacted soil around the injection head 2 to form gaps, preventing soil particles from entering the tube cavity. After the soil expansion is completed, the user pushes the pressure tube 4 by holding the handle. The pressure tube 4 drives the piston 3 to move downward inside the tube body 1, promoting growth. The bacterial solution is injected into the soil near the plant roots through the injection head 2, reducing the risk of obstruction during injection and eliminating the need for frequent manual unblocking. If the injection head 2 becomes blocked and the bacterial solution cannot be discharged, the air jet anti-blocking component 6 is activated. The output end of the electric push rod 62 moves down to push the pressure plate 63 to compress air in the air chamber 61. After the one-way valve 66 of the air inlet pipe 65 is closed, the one-way valve 66 of the exhaust pipe 64 is opened. The compressed air enters the tube body 1 through the exhaust pipe 64 and flows to the injection head 2. The airflow impacts the blockage and pushes it out to unblock the pipe, quickly clearing the injection head 2, avoiding manual intervention, ensuring smooth discharge of the bacterial solution, and improving injection continuity.
