Description

Technical Field

[0001] The invention relates to the technical field of agriculture, and in particular to a virus inoculation device for spraying rice blast stock solution on an experimental rice field. Background Art

[0002] Rice blast is one of the important diseases in rice production, posing a serious threat to rice yield and quality. Therefore, effective prevention and control of rice blast is of great significance to ensuring food security. In order to obtain rice blast-resistant plants, the experimenters will spray the rice blast stock solution on the experimental rice fields to screen out rice blast-resistant plants.

[0003] In the prior art, experimenters usually use grass carp backpack manual sprayers to spray the original solution on the experimental fields. During the spraying process, there are problems such as high labor intensity, uneven spraying, and low operating efficiency. It is difficult to meet the needs of large-scale and high-efficiency spraying. This method consumes huge manpower and time costs and is inefficient. The spraying range is limited due to the influence of body strength and device structure, and the virus original solution is sprayed unevenly, which affects the screening effect of the plants.

[0004] Therefore, the present invention provides a virus inoculation device for spraying rice blast stock solution into an experimental rice field. The spraying range of the stock solution is effectively expanded by extending and supporting the support rod. Combined with the rotation of the rotating rod, the device can further spray the stock solution in multiple directions, so that the plants in the experimental field can be sprayed evenly, thereby improving the experimental effect. Summary of the invention

[0005] To solve the above problems, the present invention provides a virus inoculation device for spraying rice blast stock solution into experimental rice fields. Through the design of the support rod and the rotating rod, the spraying pipe is extended and rotated, so that the virus stock solution can be sprayed over a large area, effectively improving the plant screening effect.

[0006] In order to achieve the above-mentioned object, the technical scheme of the present invention is as follows: a virus inoculation device for spraying rice blast stock solution into an experimental rice field, comprising an inoculation box, the outer wall of which is fixedly connected to a controller; the side wall of the inoculation box is connected to an inoculation pipe, the inoculation pipe is connected to an inoculation valve, and the controller is used to control the opening and closing of the inoculation valve;

[0007] A "∩"-shaped drainage pipe is connected to the top of the inoculation box, a drainage pump is connected inside the drainage pipe, and a controller is used to control the opening and closing of the drainage pump; a support rod is fixedly connected to the upper side wall of the inoculation box, a plurality of support frames are fixedly connected to the top of the support rod, and the support frames are all fixedly connected to the drainage pipe; the drainage pipe passes through the support rod at one end away from the inoculation box, a rotating rod is rotatably connected to the bottom of the support rod at one end away from the inoculation box, an S-shaped rotating pipe is fixedly connected to the side of the rotating rod close to the support rod, the rotating pipe passes through the side of the rotating rod close to the support rod and is connected to the drainage pipe, a plurality of fixed frames are fixedly connected to the rotating rod, and the fixed frames are all fixedly connected to the drainage pipe;

[0008] A spray assembly for adjusting the spraying amount is provided at one end of the rotating pipe away from the discharge pipe; the spray assembly comprises an annular air bag, the top of which is fixedly connected to the bottom of the end of the rotating pipe away from the discharge pipe, the side wall of which is connected to an air pump, and the bottom of which is fixedly connected to an arc-shaped spray head;

[0009] A rotating assembly for controlling the rotation of the inoculation box is provided at the bottom of the inoculation box; a driving assembly for driving the rotating rod to rotate is provided at the bottom of the support rod.

[0010] The technical principles of the above scheme are as follows:

[0011] The experimenter opens the inoculation valve through the controller and inputs the rice blast stock solution into the inoculation box; after the rice blast stock solution is input, the controller starts the drainage pump, and the drainage pump sprays the rice blast stock solution to the plants in a certain area through the drainage pipe and the rotating pipe. The controller controls the spraying component to adjust the spraying amount according to the plant conditions; during spraying, the controller controls the drive component to start, and the drive component drives the rotating rod to rotate. The rotating rod drives the rotating pipe to rotate, and through the rotation of the rotating rod, the device evenly sprays the rice blast stock solution on each plant. After the spraying of this area is completed, the controller rotates the device direction through the rotating component to spray the plants in another area.

[0012] During the spraying operation, the controller controls the air pump to adjust the size of the airbag, thereby adjusting the size of the liquid outlet of the rotating pipe to adjust the spraying amount. The steering of the device is coordinated with the steering of the rotating rod, so that the device can spray the rice blast solution over a larger range, so that each plant is evenly treated, thereby making the screening effect more comprehensive.

[0013] The above scheme has the following beneficial effects:

[0014] 1. Through the design of the support rod and the rotating rod, the spray pipe of the device of the present invention is extended and has a rotating function, which greatly increases the coverage of the spraying; compared with the traditional static spraying method, the device can cover a larger area of ​​rice fields faster and significantly improve the spraying efficiency. At the same time, the rotation of the rotating rod makes the stock solution sprayed more evenly, avoiding local overspraying or leakage, and improving the uniformity and effectiveness of the spraying. Due to the expansion of the spraying range and the improvement of the spraying uniformity, the device can more comprehensively and evenly spray the plants in the experimental field, so as to better obtain plants resistant to rice blast.

[0015] 2. The present invention utilizes the cooperation of the air bag and the air pump to effectively adjust the spraying range of the rice blast stock solution, so that the spraying range of the rice blast stock solution is wider and the experimental effect is improved.

[0016] 3. The virus inoculation device for spraying rice blast stock solution on experimental rice fields of the present invention realizes intelligent and automated design through a controller, and is easy to operate. Experimenters only need to operate through the controller to complete actions such as inputting rice blast stock solution, adjusting the spraying amount, and steering the device, which greatly reduces labor intensity.

[0017] 4. The “∩”-shaped discharge pipe and the S-shaped rotating pipe of the present invention are convenient for interconnection and also convenient for reversing the rotating pipe.

[0018] Furthermore, the rotating assembly includes a rotating block, the top of the rotating block is fixedly connected to the bottom of the inoculation box, the bottom of the rotating block is rotatably connected to a base, a first motor is fixedly connected inside the base, and the output shaft of the first motor extends into the interior of the rotating block and is coaxially fixedly connected to the rotating block.

[0019] Beneficial effect: the controller starts the first motor, the output shaft of the first motor drives the rotating block to rotate, and the rotating block drives the inoculation box to rotate, thereby realizing the steering function of the entire device, so that the spraying of rice blast stock solution can be carried out over a larger range.

[0020] Furthermore, a moving assembly is provided at the bottom of the base, and the moving assembly includes a remote control wheel, which is rotatably connected to the bottom of the base, and a controller is used to control the movement of the remote control wheel.

A main bevel gear is coaxially fixedly connected to the output shaft of the second motor, and a secondary bevel gear is sleeved on the outer wall of the rotating rod. The main bevel gear and the secondary bevel gear are meshed with each other.

[0023] Beneficial effect: The controller controls the second motor to start, the second motor output shaft drives the main bevel gear to rotate, the main bevel gear drives the secondary bevel gear to rotate, the secondary bevel gear drives the rotating rod to rotate, and the rotating rod drives the rotating pipe to rotate, so that the device can achieve large-scale spraying in a certain area.

[0025] Beneficial effects: The protective plate and the outer wall of the rotating rod provide a closed and safe operating environment for key components such as the second motor output shaft, the main bevel gear and the auxiliary bevel gear.

It also avoids harm to plants or workers.

[0026] Furthermore, a heat dissipation groove is provided at the bottom of the base for dissipating heat from the second motor.

[0027] Beneficial effect: The design of the heat sink can effectively promote the circulation of air around the motor and accelerate the dissipation of heat, thereby maintaining and improving the operating efficiency and stability of the second motor.

[0028] Furthermore, an image acquisition component for collecting plant conditions is provided on the rotating rod. The image acquisition component includes a camera, and the camera is fixedly connected to one end of the rotating rod away from the supporting rod; the controller is used to control the opening and closing of the camera.

[0029] Beneficial effects: When the device is working, the controller starts the camera, which will collect information about the growth and spraying conditions of the plants in each area. The controller will adjust the spraying of the stock solution according to the growth of the plants. For example, if all the plants in a certain area are sick and withered, there is no need to continue spraying the liquid. This will achieve more precise spraying and improve the utilization rate of the stock solution and work efficiency.

[0030] Furthermore, a sealing rubber ring is provided at the connection point between the rotating pipe and the discharge pipe.

[0031] Beneficial effect: The sealing rubber ring prevents the original liquid from leaking when the discharge pipe transports the original liquid to the rotating pipe, thereby reducing the waste of the original liquid and the impact on the experiment.

DETAILED DESCRIPTION

[0046] The bottom of the support rod 9 away from the inoculation box 1 is rotatably connected with a rotating rod 11, and an S-shaped rotating pipe 14 is fixedly bonded to the side of the rotating rod 11 close to the support rod 9. The rotating pipe 14 passes through the side of the rotating rod 11 close to the support rod 9 and is connected to the drainage pipe 8; a plurality of fixing frames are bolted and fixedly connected to the rotating pipe 14. The support frame 10 provides support and fixation for the drainage pipe 8, and the fixing frame provides support and fixation for the rotating pipe 14.

[0047] A sealing rubber ring is fixedly bonded at the connection point between the rotating pipe 14 and the discharge pipe 8; the sealing rubber ring prevents the original liquid from leaking when the discharge pipe 8 transports the original liquid to the rotating pipe 14, thereby reducing the waste of the original liquid and the impact on the experiment.

[0048] The liquid discharge pipe 8 is in a "∩" shape and the rotating pipe 14 is in an S shape, which is convenient for mutual connection and also convenient for the rotating pipe 14 to perform direction reversal and spray the original liquid.

[0049] A spray assembly for adjusting the spraying amount is provided at one end of the rotating pipe 14 away from the discharge pipe 8; the spray assembly includes an annular airbag 18, the top of the annular airbag 18 is fixedly bonded to the bottom of one end of the rotating pipe 14 away from the discharge pipe 8, the side wall of the annular airbag 18 is connected to an air pump 19, and an arc-shaped nozzle 20 is fixedly bonded to the bottom of the annular airbag 18; the arc-shaped nozzle 20 makes the spraying range of the original liquid wider.

[0050] A rotating assembly for controlling the rotation of the inoculation box 1 is provided at the bottom of the inoculation box 1; the rotating assembly includes a rotating block 16, the top of the rotating block 16 is welded to the bottom of the inoculation box 1, the bottom of the rotating block 16 is rotatably connected to the base 4, a first motor 17 is bolted fixedly connected inside the base 4, the output shaft of the first motor 17 extends to the inside of the rotating block 16 and is bolted and fixedly connected to the rotating block 16 coaxially. A moving assembly is provided at the bottom of the base 4, the moving assembly includes a remote control wheel 5, the remote control wheel 5 is rotatably connected to the bottom of the base 4, and the controller 3 is used to control the movement of the remote control wheel 5.

[0051] A driving assembly for driving the rotating rod 11 to rotate is provided at the bottom of the support rod 9. The driving assembly includes a second motor 12. The second motor 12 is bolted and fixedly connected to the bottom of the support rod 9 near one end of the rotating rod 11. The output shaft of the second motor 12 is coaxially fixedly connected to the main bevel gear. Figure 4As shown, a secondary bevel gear 22 is fixedly sleeved on the outer side wall of the rotating rod 11, and the main bevel gear and the secondary bevel gear 22 are meshed with each other.

[0052] The rotating rod 11 is provided with an image acquisition component for acquiring plant conditions, and the image acquisition component includes a camera 15, which is bolted and fixedly connected to one end of the rotating rod 11 away from the support rod 9; the controller 3 is used to control the opening and closing of the camera 15.

[0053] The specific implementation process is as follows:

[0054] The experimenter opens the inoculation valve 7 through the controller 3 and inputs the rice blast stock solution into the inoculation box 1 through the inoculation pipe 6; after the rice blast stock solution is input, the experimenter controls the remote control wheel 5 through the controller 3 to move the device to the experimental field area; the design of the remote control wheel 5 enables the entire device to move horizontally in the entire experimental field, greatly increasing the spraying range of the stock solution.

[0055] After the controller 3 recognizes through the camera 15 that the device has reached the designated area, the controller 3 starts the drainage pump 21, and the drainage pump 21 sprays the rice blast stock solution in the inoculation box 1 to the plants in a certain area through the drainage pipe 8 and the rotating pipe 14. The controller 3 controls the output power of the drainage pump 21 according to the plant conditions recognized by the camera 15, thereby adjusting the spraying amount of the stock solution; for example, if the plants in a certain area have withered due to rice blast, the stock solution will no longer be sprayed on the plants in this area. After the controller 3 recognizes this situation through the camera 15, the drainage pump 21 is turned off and the drainage is stopped to reduce the waste of the stock solution. If the plant grows luxuriantly, the controller 3 controls the drainage pump 21 to increase the power to further test the disease resistance of the plant, thereby helping the experimenter to obtain better plants.

[0056] A liquid outlet is provided at one end of the rotating pipe 14 close to the annular airbag 18; the controller 3 will also adjust the operation of the air pump 19 according to the plant distance recognized by the camera 15, change the expansion and contraction of the annular airbag 18, and thus adjust the size of the liquid outlet; the larger the expansion volume of the annular airbag 18, the smaller the cross-sectional area of ​​the liquid outlet, the faster the flow rate of the original liquid, the greater the spraying distance, and vice versa.

[0057] For example, when the plants are far away or the device is not convenient to move to that area, the controller 3 controls the air pump 19 to inhale, the annular airbag 18 expands, and the cross-sectional area of ​​the liquid outlet decreases. Since the power of the drainage pump 21 remains unchanged and the drainage volume remains unchanged, the drainage speed will increase and the spraying distance of the stock solution will increase, thereby achieving the spraying of the stock solution on plants at different distances, making the spraying range wider and more uniform.

[0058] During spraying, the controller 3 controls the second motor 12 to start, the output shaft of the second motor 12 drives the main bevel gear to rotate, the main bevel gear drives the secondary bevel gear 22 to rotate, the secondary bevel gear 22 drives the rotating rod 11 to rotate, and the rotating rod 11 drives the rotating pipe 14 to rotate, so that the device can achieve circumferential spraying in a certain area, thereby increasing the spraying range of the original liquid in the area.

[0059] After the spraying of this area is completed, the controller 3 starts the first motor 17, the output shaft of the first motor 17 drives the rotating block 16 to rotate, the rotating block 16 drives the inoculation box 1 to rotate, and the rotation of the inoculation box 1 can drive the drainage pipe 8 and the rotating pipe 14 to rotate greatly, thereby realizing the steering function of the entire device, so that the rice blast stock solution can be sprayed in a larger range; the large-range rotation of the device is combined with the small-range rotation of the rotating pipe 14, so that the device can adjust the spraying range more widely and accurately, effectively improving the spraying effect of the stock solution, so that each plant is sprayed evenly, so that the experimenter can better obtain plants resistant to rice blast.

[0060] Through the design of the support rod 9 and the rotating rod 11, the spraying pipe of the device is extended and has a rotation function, which greatly increases the coverage of the spraying. Compared with the traditional static spraying method, the device can cover a larger area of ​​rice fields faster and significantly improve the spraying efficiency. The controller 3 realizes intelligent and automated design, and the operation is simple. The experimenter only needs to operate through the controller 3 to complete the input of rice blast stock solution, the adjustment of the spraying amount, and the steering of the device, which greatly reduces the labor intensity.

[0061] At the same time, the rotation of the rotating rod 11 makes the spraying more uniform, avoids local overspraying or leakage, and improves the uniformity and effectiveness of the spraying.

[0062] Due to the expansion of the spraying range and the improvement of spraying uniformity, the device can more comprehensively evaluate the resistance of different plants to rice blast. This helps to screen out more resistant varieties and provide strong support for agricultural production and breeding research.

[0063] Embodiment 2:

[0064] As attached Figure 1 , Figure 2 , Figure 4 As shown, the difference from the above embodiment is that the bottom bolt of the support rod 9 close to the second motor 12 is fixedly connected with a protective plate 13, and the rotating rod 11, the output shaft of the second motor 12, the main bevel gear and the auxiliary bevel gear 22 are all located in the protective plate 13 and rotate with the protective plate 13.

[0065] The specific implementation process is as follows:

[0066] When the second motor 12, the main bevel gear and the auxiliary bevel gear 22 rotate, the protective plate 13 cooperates with the outer wall of the rotating rod 11 to provide a relatively closed and safe operating environment for key components such as the output shaft of the second motor 12, the main bevel gear and the auxiliary bevel gear 22. This effectively prevents the intrusion of external impurities such as dust, moisture, and weeds, reduces the risk of component damage, and extends the service life of the equipment. At the same time, it also avoids harm to plants or workers.

[0067] Embodiment 3:

[0068] As attached Figure 1 , Figure 2 As shown, the difference from the above embodiment is that a heat dissipation groove is opened at the bottom of the base 4 for dissipating heat of the second motor 12.

[0069] The specific implementation process is as follows:

[0070] When the second motor 12 is operating, a large amount of heat will be generated. The design of the heat dissipation slot can effectively promote the circulation of air around the motor and accelerate the dissipation of heat, thereby improving the operating efficiency and stability of the second motor 12.

[0071] Embodiment 4:

[0072] As attached Figure 1 , Figure 2 As shown, the difference from the above embodiment is that a display 2 is fixedly connected to the side wall of the inoculation box 1, and the controller 3 is used to control the opening and closing of the display 2.

[0073] The specific implementation process is as follows: the experimenter can observe the plant image and the image of the stock solution spraying collected by the camera 15 through the display 2, so that the experimenter can understand the growth of the plant and the stock solution spraying more intuitively.

[0074] Embodiment 5:

[0075] As attached Figure 1 , Figure 2 As shown, the difference from the above embodiment is that a plurality of counterweight grooves are opened inside the base 4, and counterweight blocks 23 are placed inside the counterweight grooves.

[0076] The specific implementation process is as follows:

[0077] When the device is moving, the counterweight 23 can increase the stability of the device. The counterweight 23 uses its own gravity to offset the gravity of the support rod 9 and the rotating rod 11, thereby preventing the device from tipping over due to the excessive length of the support rod 9 and the rotating rod 11.

[0078] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
