Description

Technical Field

[0001] The present invention relates to the technical field of fruit and vegetable planting, and particularly to an insect-proof device for cultivating citrus seedlings and a method for preventing insects on seedlings. Background Art

[0002] During the cultivation of citrus seedlings, various pests will damage the seedlings. During the process of dealing with pests on the stems and leaves of the seedlings, it is necessary to kill and eliminate the pests. The main way to deal with pests is to kill and eliminate the pests through pesticides, so as to protect the growth of citrus seedlings and then improve the survival rate of citrus seedlings. This is the technical inspiration for killing and eliminating pests on citrus seedlings;

[0003] The following problems have been found in the research on preventing insects on citrus seedlings:

[0004] When dealing with pests on citrus seedlings, manual killing and elimination and pest prevention in the selection of citrus seedlings are carried out. However, during the cultivation process of the seedlings, there may be a situation where pests grow, and the workload of manual killing and elimination is relatively large. During the process of preventing insects through manual killing and elimination and the selection of citrus seedlings, the seedlings cannot be completely protected, resulting in pests continuously damaging the seedlings, so that the purpose of improving the survival rate of citrus seedlings cannot be achieved;

[0005] Currently, the prior art CN1144511785A, a maintenance device and cultivation method for planting fruit and vegetable seedlings with high survival rate, discloses a protection device for fruit and vegetable seedlings. The invention can detect the temperature and humidity in the inner cavity of the box through the cooperation of a temperature sensor and a humidity sensor. When the detected humidity is low, the water pump is turned on to work through the PLC controller. The water source in the inner cavity of the water tank is pumped out through the water pump and conveyed into the inner cavity of the drain pipe through the water delivery pipe. The water source is atomized and sprayed through the atomizing nozzle, so that the water source is sprayed on the bottom of the placement grid frame, so that the water source penetrates into the roots of the fruit and vegetable seedlings. When the detected temperature is low, the heating plate and the fan are turned on to work through the PLC controller. The outside air is extracted through the fan, and the air is heated through the heating plate. The hot air is conveyed into the inner cavity of the exhaust hood through the air delivery pipe and discharged through the through hole for heating. The motor is turned on to work through the PLC controller, and the fan blade is driven to rotate by the motor, so that the heat can be evenly distributed;

[0006] The present invention can mainly solve the problem that the seedlings cannot be completely protected during the process of preventing insects through manual killing and elimination and the selection of citrus seedlings, resulting in the seedlings not being able to achieve the improvement of the survival rate. Summary of the Invention

A secondary sleeve box is arranged on one side of the support sleeve block. A secondary spring is arranged inside the secondary sleeve box. A driving sleeve block is arranged on one side of the main sleeve box. A main spring is arranged on one side of the driving sleeve block. A bottom plate is installed on one side of the support shaft.

[0012] Further, the cultivation rack is arranged in a grid shape. Openings are formed on the inner side of the lateral side of the cultivation rack. The top of the cultivation rack is all open. The protective rack is arranged at the top opening of the cultivation rack. Through holes are formed on the longitudinal side of its top. And the bottom of the protective rack is open. The longitudinal side of the protective rack is nested on the outer side of the conduit.

[0013] Further, the secondary pipe is arranged in a "T" shape. Its longitudinal end is embedded in the through hole on the longitudinal side of the top of the protective rack and is nested on the conduit. The length of the secondary pipe is less than the length of the conduit.

[0014] Further, the bottom plate passes through the opening on the inner side of the cultivation rack through the support shaft, and one side of the support shaft is arranged in a rack shape. The bottom of the driving shaft and the side close to the driving sub-shaft are both arranged in an open shape. The driving sub-shaft and the driving shaft are symmetrically arranged and are in a fitting arrangement. A rack is arranged above the inner wall of the driving sub-shaft, and this rack meshes with the transmission gear. The driving sub-shaft meshes with the driving gear. The sides of the driving shaft and the driving sub-shaft adjacent to the driving gear are arranged in a rack shape.

[0015] Further, a rack groove is opened on one side of the top of the main sleeve box and meshes with the transmission gear. One side of the main sleeve box is arranged in an open shape, and a driving sleeve block is arranged in its opening. One end of the main spring away from the driving sleeve block is connected to the inner wall of the open side of the main sleeve box.

[0016] Further, one side of the auxiliary sleeve box close to the support sleeve block is arranged in an open shape, and a support sleeve block is arranged in its opening. One side of the auxiliary spring away from the auxiliary sleeve box is connected to one side of the support sleeve block, and the initial state of the auxiliary spring is in a compressed state. The side of the auxiliary sleeve box away from the support sleeve block is connected to the inner wall of the driving shaft, and the auxiliary sleeve box is arranged at a position ten centimeters away from the bottom opening of the driving shaft. The width of the auxiliary sleeve box plus the width of the support sleeve block is equal to the width of the driving shaft, and the support sleeve block is in a fitting arrangement with the main sleeve box.

[0017] Further, for the method of preventing pests from attacking seedlings in citrus planting, the specific operation steps are as follows:

[0018] S1: Plant the seedlings on the upper surface of the bottom plate. Open the cover plate through the handle and place the required water, nutrient solution or insecticide into the water pump box.

[0019] S2: Start the water pump box. The water pump box pumps the water, nutrient solution or insecticide in the fluid box into the pipeline group. The water, nutrient solution or insecticide enters the pipeline group under pressure, so that the water, nutrient solution or insecticide fills the pipeline group and then enters the conduit.

[0020] S3: The conduit guides it to the atomizing nozzle through the auxiliary pipe, and the atomizing nozzle sprays the water, nutrient solution or insecticide onto the seedlings.

[0021] S4: As the weight of the seedlings increases during growth, the pressure plate drives the support shaft to move downward under the action of gravity. The support shaft simultaneously drives the driving gear to rotate, causing the driving sub-shaft to move upward. The driving sub-shaft drives the transmission gear to rotate through the rack on the inner wall. While the transmission gear rotates, it drives the main sleeve box to move toward the driving sleeve block side through the rack groove on one side of the top of the main sleeve box, and at the same time compresses the main spring.

[0022] S5: The engagement of the transmission gear through the rack slot at the top of the main sleeve box is cancelled, the pressure on the auxiliary spring disappears, and the support sleeve block moves with the main sleeve box. During this process, the main sleeve box slides downward under the action of its own gravity, the drive shaft continuously moves upward through the drive gear and pushes the protective frame, causing the drive shaft to continuously move away from the pipeline group, and the pipeline group continuously cancels the limit on the main sleeve box. Thus, the main sleeve box continuously slides downward under the action of gravity, thereby preventing pests on each seedling in the cultivation rack grid from damaging other seedlings;

[0023] S6: The upward movement of the protective frame drives the auxiliary pipe to move upward, increasing the length between the auxiliary pipe and the conduit and continuously maintaining the connection. At the same time, the atomizing nozzle continuously remains horizontally up and down with the height of the seedling stems and leaves. Beneficial effects

[0024] 1. The water pump box pumps water, nutrient solution or pesticide inside the fluid box into the pipeline group. The water, nutrient solution or pesticide enters the pipeline group under pressure, filling the pipeline group and then entering the conduit. The conduit guides it through the auxiliary pipe to the atomizing nozzle, and the atomizing nozzle sprays the water, nutrient solution or pesticide onto the seedlings, thereby protecting the seedlings;

[0025] 2. As the seedlings grow and their own weight increases, the seedlings press downward on the bottom plate under their own gravity, causing the support shaft to drive the drive gear to rotate and the drive sub - shaft to move upward. The drive sub - shaft drives the transmission gear to rotate through the internal wall rack, and while the transmission gear rotates, it drives the main sleeve box to move towards the drive sleeve block side through the rack slot on one side of the top of the main sleeve box, and at the same time compresses the main spring. At this time, the engagement of the transmission gear through the rack slot at the top of the main sleeve box is cancelled, the pressure on the auxiliary spring disappears, and the support sleeve block moves with the main sleeve box. During this process, the main sleeve box slides downward under the action of its own gravity, the drive shaft continuously moves upward through the drive gear and pushes the protective frame, causing the drive shaft to continuously move away from the pipeline group, and the pipeline group continuously cancels the limit on the main sleeve box. Thus, the main sleeve box continuously slides downward under the action of gravity. As the growth height of the seedlings increases, each seedling in the cultivation rack grid is separated by the protective frame, preventing the seedlings from growing obliquely and the branches and leaves of the seedlings from crossing, thereby improving the survival rate and vigor;

[0026] 3. The protective frame gradually moves upward following the growth height of the seedlings, and the auxiliary pipe moves upward with the protective frame at the same time, making the atomizing nozzle continuously remain horizontally up and down with the seedling stems and leaves, thereby facilitating the maintenance of the seedlings and the killing of pests.

[0049] For the protection rack 401, the protection rack 401 is arranged at the top opening of the culture rack 4. On the longitudinal side of its top, there is a through hole, and the bottom of the protection rack 401 is open. The longitudinal side of the protection rack 401 is nested on the outer side surface of the conduit 205;

[0050] For the secondary pipe 402, the secondary pipe 402 is arranged in a "T" shape. Its longitudinal end is embedded in the through hole on the longitudinal side of the top of the protection rack 401 and is nested on the conduit 205. The length of the secondary pipe 402 is less than the length of the conduit 205;

[0051] For the bottom plate 404, the bottom plate 404 passes through the opening on the inner side surface of the culture rack 4 through the support shaft 405. On one side of its support shaft 405, it is arranged in a rack shape. The bottom of the driving shaft 406 and the side close to the driving secondary shaft 409 are both open. The driving secondary shaft 409 and the driving shaft 406 are symmetrically arranged and are in a fitting arrangement. Above the inner wall of the driving secondary shaft 409, there is a rack, which meshes with the transmission gear 408. The driving secondary shaft 409 meshes with the driving gear 407. The sides of the driving shaft 406 and the driving secondary shaft 409 adjacent to the driving gear 407 are arranged in a rack shape;

[0052] The main cartridge 410 has a rack groove formed on one side of its top, which meshes with the transmission gear 408.

[0053] The auxiliary cartridge 413 has an opening on one side close to the support sleeve block 414. A support sleeve block 414 is arranged inside the opening. One side of the auxiliary spring 415 away from the auxiliary cartridge 413 is connected to one side of the support sleeve block 414, and the initial state of the auxiliary spring 415 is a compressed state. The side of the auxiliary cartridge 413 away from the support sleeve block 414 is connected to the inner wall of the drive shaft 406, and the auxiliary cartridge 413 is arranged at a position ten centimeters away from the bottom opening of the drive shaft 406.

The support sleeve block 414 is arranged in a fitting manner with the main cartridge 410;

[0054] The support shaft 405 is arranged in a mirror image with the drive shaft 406 and the drive auxiliary shaft 409;

[0055] The seedlings are planted on the upper surface of the bottom plate 404. The water pump box 201 pumps water, nutrient solution or pesticide into the pipeline group 204 and enters the inside of the conduit 205. The conduit 205 guides it through the auxiliary pipe 402 to the atomizing nozzle 403. The atomizing nozzle 403 sprays water, nutrient solution or pesticide onto the seedlings, thereby protecting the seedlings. During the growth process of the seedlings, their own weight increases, causing the seedlings to press down on the bottom plate 404 by their own gravity and move it downward. The bottom plate 404 drives the support shaft 405 to move downward in the opening on the inner side of the cultivation rack 4. The support shaft 405 simultaneously drives the driving gear 407 to rotate, causing the driving auxiliary shaft 409 to move upward. The driving auxiliary shaft 409 drives the transmission gear 408 to rotate through the inner wall rack. While the transmission gear 408 rotates, it drives the main sleeve box 410 to move toward the driving sleeve block 412 through the rack groove on one side of the top of the main sleeve box 410, and simultaneously compresses the main spring 411. At this time, the transmission gear 408 cancels the engagement through the rack groove on the top of the main sleeve box 410, and the pressure on the auxiliary spring 415 disappears, causing the support sleeve block 414 to move with the main sleeve box 410. During this process, the main sleeve box 410 slides downward under its own gravity. The driving shaft 406 continuously moves upward through the driving gear 407 and pushes the protective frame 401, causing the driving shaft 406 to continuously move away from the pipeline group 204. The pipeline group 204 continuously cancels the limit on the main sleeve box 410, so that the main sleeve box 410 continuously slides downward under the action of gravity. Furthermore, as the growth height of the seedlings increases, each seedling in the grid of the cultivation rack 4 is separated by the protective frame 401, preventing the seedlings from growing obliquely and the branches and leaves of the seedlings from crossing, thereby improving the survival rate and vitality. The auxiliary pipe 402 simultaneously moves upward with the protective frame 401, causing the atomizing nozzle 403 to continuously maintain a horizontal up-and-down position with the seedling stems and leaves, which is convenient for maintaining the seedlings and killing pests; Example

[0056] A method for preventing pests of seedlings in citrus seedling cultivation, the specific operation steps are as follows:

[0057] S1: Plant the seedlings on the upper surface of the bottom plate 404. Open the cover plate 202 through the handle 203, and place the required water, nutrient solution or pesticide into the water pump box 201;

[0058] S2: Start the water pump box 201. The water pump box 201 pumps the water, nutrient solution or pesticide in the fluid tank 2 into the pipeline group 204. The water, nutrient solution or pesticide enters the pipeline group 204 under pressure, causing the water, nutrient solution or pesticide to fill the pipeline group 204 and then enter the conduit 205;

[0059] S3: The conduit 205 guides it through the auxiliary pipe 402 to the atomizing nozzle 403, and the atomizing nozzle 403 sprays water, nutrient solution or pesticide onto the seedlings;

[0060] S4: As the weight of the seedling increases during growth, the pressing plate 404 drives the support shaft 405 to move downward under the action of gravity. The support shaft 405 simultaneously drives the driving gear 407 to rotate, causing the driven sub-shaft 409 to move upward. The driven sub-shaft 409 drives the transmission gear 408 to rotate through the internal wall rack, and while the transmission gear 408 rotates, it drives the main sleeve box 410 to move toward the driving sleeve block 412 through the rack groove on one side of the top of the main sleeve box 410, and simultaneously compresses the main spring 411;

[0061] S5: The transmission gear 408 cancels the engagement with the rack groove on the top of the main sleeve box 410. The pressure on the auxiliary spring 415 disappears, causing the support sleeve block 414 to move with the main sleeve box 410. During this process, the main sleeve box 410 slides downward under its own gravity. The driving shaft 406 continuously moves upward through the driving gear 407 and pushes the protective frame 401, causing the driving shaft 406 to continuously move away from the pipeline group 204. The pipeline group 204 continuously cancels the limit on the main sleeve box 410, so that the main sleeve box 410 continuously slides downward under the action of gravity, thereby preventing pests on each seedling in the grid of the cultivation rack 4 from damaging other seedlings;

[0062] S6: The upward movement of the protective frame 401 drives the auxiliary pipe 402 to move upward, increasing the length between the auxiliary pipe 402 and the conduit 205 and continuously maintaining the connection, and at the same time causing the atomizing nozzle 403 to continuously maintain a horizontal up-and-down position with the height of the seedling stems and leaves;

7. A method for preventing pests on citrus seedlings used in citrus cultivation, characterized in that, For an insect-proof device for cultivating citrus seedlings according to any one of claims 1-6, the specific operation steps are as follows: S1: Plant the seedlings on the upper surface of the bottom plate. Open the cover plate through the handle and place the required water, nutrient solution or insecticide into the water pump box. S2: Start the water pump box. The water pump box pumps the water, nutrient solution or insecticide in the fluid box into the pipeline group. The water, nutrient solution or insecticide enters the pipeline group under pressure, so that the water, nutrient solution or insecticide fills the pipeline group and then enters the conduit. S3: The conduit guides it to the atomizing nozzle through the auxiliary pipe, and the atomizing nozzle sprays the water, nutrient solution or insecticide onto the seedlings. S4: As the weight of the seedlings increases during growth, the pressing plate drives the support shaft to move downward under the action of gravity. The support shaft simultaneously drives the driving gear to rotate, causing the driving auxiliary shaft to move upward. The driving auxiliary shaft drives the transmission gear to rotate through the internal wall rack, and while the transmission gear rotates, it drives the main sleeve box to move toward the driving sleeve block through the rack groove on one side of the top of the main sleeve box, and simultaneously compresses the main spring. S5: The transmission gear cancels the engagement with the rack groove on the top of the main sleeve box. The pressure on the auxiliary spring disappears, causing the support sleeve block to move with the main sleeve box. During this process, the main sleeve box slides downward under its own gravity, and the drive shaft continuously moves upward through the drive gear and pushes the protective frame, so that the drive shaft continuously moves away from the pipeline group, and the pipeline group continuously cancels the limit on the main sleeve box. Thus, the main sleeve box continuously slides downward under the action of gravity, thereby preventing pests on each seedling in the grid of the cultivation rack from damaging other seedlings. S6: The upward movement of the protective frame drives the auxiliary pipe to move upward, increasing the length between the auxiliary pipe and the conduit and continuously maintaining the connection, and at the same time keeping the atomizing nozzle continuously at the same horizontal height as the seedlings' stems and leaves.
