Description

Technical Field

[0001] The invention relates to the technical field of farmland devices, and in particular to a pest migration blocking device at a farmland boundary and a use method thereof. Background Art

[0002] Cutworms and cotton bollworms are common pests in wheat and alfalfa fields. They feed on a wide range of plants, are highly resistant to pesticides, reproduce quickly, and are very harmful. They will eat the tender leaves and stems of plants, causing damage to the plants. In severe cases, they will bite off the roots of young plants and destroy large tracts of farmland.

[0003] When planting crops, since different crops mature at different times, if they are planted together, the harvest periods can be staggered, the growing period of the farmland can be extended, and the utilization rate can be improved. For example, early-maturing crops can be harvested early, and late-maturing crops can be sown later. This ensures that there are crops in production on the farmland throughout the growing season, increases the total output of agricultural products, and saves a lot of labor.

[0004] When two crops with different maturity periods are planted adjacent to each other, pest migration will occur at the junction of the farmlands, migrating from the more mature farmlands to the less mature farmlands, eating seedlings and young stems, leading to the continuous spread of pests and seriously reducing the yield of the farmlands. Take the junction of wheat fields and alfalfa fields in the Nandagang area of ​​Cangzhou City, Hebei Province as an example. In June of each year, wheat has basically entered its maturity period, while alfalfa is still in its young and tender period. As a result, cutworms and bollworms in the wheat fields will cross the border into the alfalfa fields because there are no young leaves and other food, and eat alfalfa seedlings, seriously endangering the growth of alfalfa. The current prevention and control method generally involves spraying pesticides in farmlands, which is costly and inefficient. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1 like Figures 1 to 8 As shown, this embodiment proposes a pest migration blocking device at the junction of farmlands, including a V-shaped ditch 1, a rainproof component, a blocking component, a supplementary component, a cleaning component, a drainage ditch 2 and a collecting component. The V-shaped ditch 1 is arranged at the junction of two farmlands, and the length of the V-shaped ditch 1 is equal to the length of the border between the two farmlands, wherein the width of the V-shaped ditch 1 is 20-25cm and the depth is 10-15cm. The V-shaped ditch 1 is covered with an isolation film, and the boundary area of ​​the V-shaped ditch 1 is slightly higher than the two farmlands. The rainproof component is arranged on the upper part of the V-shaped ditch 1, and the rainproof component is fixedly installed at the junction of the two farmlands for preventing To prevent rainwater from entering the V-shaped ditch 1, the rainproof assembly includes an arched bamboo frame 3, a plastic film 4 and a connecting plate 5. A plurality of arched bamboo frames 3 are fixedly installed at equal distances at the junction of two farmlands, wherein the boundary area of ​​the V-shaped ditch 1 is located at the lower part of the arched bamboo frame 3, and the height of the arched bamboo frame 3 is 10-20 cm. Plastic film 4 is covered and fixedly installed between the plurality of arched bamboo frames 3, and the edge of the plastic film 4 is 10 cm away from the boundary of the V-shaped ditch 1. A gap is retained between the edge of the plastic film 4 and the ground, and a connecting plate 5 is symmetrically and fixedly installed between every two adjacent arched bamboo frames 3.

[0025] Specifically, when two crops with different maturity stages are planted adjacent to each other, take wheat and alfalfa as an example, in June of each year, when wheat is already mature, the sugar and protein content of wheat straw decreases, resulting in a decrease in its nutritional value, and the cellulose content of wheat straw is very high at this time. Although many insects can digest cellulose, their digestive systems usually find it difficult to effectively decompose this complex polysaccharide, which means that although these insects may eat wheat straw, it is difficult for them to obtain enough nutrition from it to meet their growth and development needs. Therefore, these insects may go to the alfalfa field bordering the wheat field. At this time, the alfalfa is still in the seedling stage, which causes a large number of insects, such as cutworms and cotton bollworms, to enter the alfalfa field and eat the alfalfa. In order to prevent pests from migrating from a high-maturity farmland to a low-maturity farmland, eating the seedlings, affecting the growth of the seedlings, and endangering the yield of the farmland, in order to inhibit the spread of pests, a V-shaped ditch 1 is opened at the junction of the farmland at this time. In order to prevent the blocking agent from contaminating the soil, a layer of isolation film is also laid on the V-shaped ditch 1, thereby The agent is separated from the soil, and then the blocking component is installed. At this time, a suitable blocking component is set according to the length of the V-shaped groove 1, and then the blocking component is installed at the bottom of the V-shaped groove 1. At this time, the arched bamboo frame 3 is installed. In order to improve the stability of the arched bamboo frame 3, the connecting plate 5 needs to be installed. In order to avoid the influence of rain on the blocking component, a plastic film 4 needs to be laid on the arched bamboo frame 3, and there is a certain gap between the edge of the plastic film 4 and the ground. When the pests in the highly mature farmland migrate to the less mature farmland, the pests will enter the V-shaped groove 1 through the gap between the plastic film 4 and the ground. Through the setting of the blocking component, the supplementary component is started to add the agent to the blocking component, thereby killing the pests entering the V-shaped groove 1 and preventing the migration of the pests from the root. Compared with the method of spraying pesticides in the prior art, the insecticide effect is improved. After a period of time, a certain amount of pest corpses will accumulate in the V-shaped groove 1. At this time, the cleaning component is started to flush the pests into the drainage ditch 2, and then the pest corpses are collected and centrally processed through the setting of the collecting component.

[0026] like Figure 3 , Figure 4 As shown, the blocking component is installed inside the V-shaped groove 1 to kill pests entering the V-shaped groove 1. The blocking component includes a pesticide groove 6, which is fixedly installed at the bottom of the V-shaped groove 1. The position of the pesticide groove 6 is higher than the drainage ditch 2. The structure of the pesticide groove 6 is V-shaped and adapted to the V-shaped groove 1. The length of the pesticide groove 6 is equal to that of the V-shaped groove 1.

[0027] Specifically, when it is necessary to kill the pests entering the V-shaped groove 1, it is necessary to add pesticides into the pesticide groove 6. The setting of the pesticide groove 6 can prevent the pesticide from falling into the V-shaped groove 1, reduce the risk of the pesticide infiltrating into the soil, and avoid pollution.

[0028] like Figure 5 As shown, the supplementary component is installed inside the rainproof component, and the supplementary component is located on the upper part of the blocking component, and is used to add new medicine to the blocking component in time. The supplementary component includes a mounting plate 7, an adding pipe 8, a dosing nozzle 9, a first joint 10 and a fixing part. A mounting plate 7 is fixedly installed between each two adjacent arched bamboo frames 3, and the mounting plate 7 is located on the upper part of the medicine groove 6. The adding pipe 8 is arranged on the upper part of the medicine groove 6. The length of the adding pipe 8 is equal to the length of the medicine groove 6. A plurality of dosing nozzles 9 are connected to the adding pipe 8 at equal distances, and the discharge port of the dosing nozzle 9 is located on the upper part of the medicine groove 6. The first joint 10 is connected to the end of the adding pipe 8, and a plurality of mounting plates 7 are installed with fixing parts for fixing the position of the adding pipe 8.

[0029] Specifically, when installing the addition pipe 8, after installing the arched bamboo frame 3 and the connecting plate 5, the mounting plate 7 is installed, and then the addition pipe 8 is installed at the lower part of the plurality of mounting plates 7 through the setting of the fixing part. When it is necessary to add medicine, the pipeline for outputting the medicine is connected to the first joint 10, and then the medicine is injected into the addition pipe 8 through the setting of the first joint 10, and then the medicine entering the addition pipe 8 is discharged through the setting of the dosing nozzle 9, and stored in the medicine tank 6. After adding the medicine, the first joint 10 is closed, and then the pipeline for outputting the medicine is disconnected from the first joint 10.

[0030] The above, such as Figure 6 As shown, the fixing part includes an upper fixing ring 11 and a lower fixing ring 12. The upper fixing ring 11 is fixedly installed at both ends of the bottom of each mounting plate 7, and the upper fixing ring 11 abuts against the adding tube 8. The lower fixing ring 12 is fixedly installed at the lower part of the upper fixing ring 11, and the lower fixing ring 12 abuts against the adding tube 8.

[0031] Specifically, when installing the addition tube 8, place the addition tube 8 at the bottom of the upper fixing ring 11, then install the corresponding lower fixing ring 12 at the bottom of the corresponding upper fixing ring 11, connect the two, and repeat this step until all the upper fixing rings 11 are installed with the lower fixing ring 12. The addition tube 8 can be installed by setting the lower fixing ring 12.

[0032] like Figure 7 As shown, the cleaning component is installed inside the rainproof component and is used to clean up the bodies of killed pests in time. The cleaning component includes a drain pipe 13, a mounting ring 14, a connecting pipe 15, a second joint 16 and a cleaning part. The drain pipes 13 are symmetrically arranged on the top of the V-shaped groove 1, and a mounting ring 14 is symmetrically and fixedly installed inside each arched bamboo frame 3. The mounting ring 14 is adapted to the drain pipe 13, the connecting pipe 15 is connected between the two drain pipes 13, and the second joint 16 is connected to the connecting pipe 15. Cleaning parts are installed on both drain pipes 13 to clean up the bodies of pests.

[0033] Specifically, after adding the agent into the flushing agent groove 6, after a period of time, the agent in the agent groove 6 loses its effect, and a large number of dead insects have gathered in the V-shaped groove 1. At this time, the dead insects need to be cleaned up. At this time, the water source is connected to the second joint 16, and the water will enter the connecting pipe 15 and enter the two drain pipes 13 at the same time through the connecting pipe 15. At this time, the cleaning part is started, and through the setting of the cleaning part, the dead insects in the V-shaped groove 1 are cleaned and sent to the drain ditch 2.

[0034] The above, such as Figure 7 As shown, the cleaning part includes a water spray head 17, and the two drainage pipes 13 are evenly connected with the water spray heads 17, the water spray heads 17 are arranged obliquely, and the inclination direction of the water spray heads 17 is toward the position of the drainage ditch 2, wherein the discharge port of the water spray head 17 is aligned with the position of the reagent tank 6.

[0035] Specifically, after water enters the connecting pipe 15 , the water spray head 17 is started. Due to the inclined arrangement of the water spray head 17 , the dead insects in the V-shaped groove 1 can be flushed, and the dead insects can also be flushed into the drainage ditch 2 .

[0036] like Figure 8 As shown, a drain ditch 2 is provided at the drainage part of the V-shaped ditch 1, and the bottom of the drain ditch 2 is lower than the blocking component. A collecting component is provided on the drain ditch 2 for collecting the cleaned up dead insect bodies. The collecting component includes a placing rack 18 and a filter plate 19. The placing racks 18 are symmetrically and detachably installed on the drain ditch 2, wherein the outlet of the V-shaped ditch 1 is located between the two placing racks 18, and filter plates 19 are rotatably installed on the two placing racks 18. The two filter plates 19 are symmetrically arranged, and the filter plates 19 are adapted to the drain ditch 2.

[0037] Specifically, when water flushes the V-shaped groove 1 and carries the dead bodies of pests into the drain ditch 2, the corresponding two placement racks 18 are installed at the set position, and then the filter plate 19 is placed so that the filter plate 19 abuts against the inner wall of the drain ditch 2. Then, the water carrying the dead bodies of pests will flow toward the position of the filter plate 19, and the water will pass through the filter plate 19 and be discharged through the drain trough, while the dead bodies of pests will be blocked by the filter plate 19 and gathered in the drain ditch 2 near the filter plate 19, and then they will be collected and processed centrally.

[0038] The above, such as Figure 8 As shown, it also includes a pressing plate 20. The bottom end of the filter plate 19 is fixedly mounted with a pressing plate 20. The pressing plate 20 is adapted to the bottom of the drainage ditch 2, and the two pressing plates 20 are symmetrically arranged.

[0039] Specifically, by disposing the pressing plate 20 , when water flows in the drainage ditch 2 , the pressing plate 20 is affected by the pressure of the water, so that the filter plate 19 is closely attached to the drainage ditch 2 , which can reduce the impact on the filter plate 19 .

[0040] To sum up, when two crops with different maturity stages are planted adjacent to each other, in order to prevent pests from migrating from a farmland with a higher maturity to a farmland with a lower maturity, eating the seedlings, affecting the growth of the seedlings, and endangering the yield of the farmland, in order to inhibit the spread of pests, a V-shaped groove 1 is opened at the junction of the farmlands. In order to prevent the blocking of the pesticide from polluting the soil, a layer of isolation film is laid on the V-shaped groove 1 to separate the pesticide from the soil, and then the pesticide groove 6 is installed. At this time, a suitable pesticide groove 6 is set according to the length of the V-shaped groove 1, and then the pesticide groove 6 is installed at the bottom of the V-shaped groove 1. When it is necessary to kill the pests entering the V-shaped groove 1, it is also necessary to add pesticides to the pesticide groove 6. The setting of the pesticide groove 6 can prevent the pesticide from falling into the V-shaped groove 1, thereby reducing the risk of the pesticide infiltrating into the soil and avoiding pollution.

[0041] At this time, the arched bamboo frame 3 is installed. In order to improve the stability of the arched bamboo frame 3, the connecting plate 5 needs to be installed, and then the mounting plate 7 is installed. Then, the adding pipe 8 is installed at the lower part of the multiple mounting plates 7 through the setting of the upper fixing ring 11 and the lower fixing ring 12. In order to avoid the influence of rainwater on the agent tank 6, it is also necessary to lay a plastic film 4 on the arched bamboo frame 3, and there is a certain gap between the edge of the plastic film 4 and the ground. When the pests in the highly mature farmland migrate to the less mature farmland, the pests will enter the V-shaped groove 1 through the gap between the plastic film 4 and the ground.

[0042] At this time, the pipeline for outputting the agent is connected to the first joint 10, and then the agent is injected into the adding pipe 8 through the setting of the first joint 10, and then the agent entering the adding pipe 8 is discharged through the setting of the dosing nozzle 9, and stored in the agent tank 6. After adding the agent, the first joint 10 is closed, and then the pipeline for outputting the agent is disconnected from the first joint 10, so that the pests entering the V-shaped groove 1 are killed by the agent, and the migration of pests is prevented from the root. Compared with the method of spraying pesticides in the prior art, the insecticide effect is improved.

[0043] After a period of time, the agent in the agent tank 6 loses its effect, and a large number of dead insects have gathered in the V-shaped groove 1. At this time, the dead insects need to be cleaned up. At this time, the water source is connected to the second joint 16, and the water will enter the connecting pipe 15 and enter the two drainage pipes 13 at the same time through the connecting pipe 15. When the water enters the connecting pipe 15, the sprinkler head 17 is started. Due to the inclined arrangement of the sprinkler head 17, the dead insects in the V-shaped groove 1 can be continuously flushed and flushed into the drainage ditch 2.

[0044] When water flushes the V-shaped groove 1 and carries the dead bodies of pests into the drain ditch 2, the corresponding two placement racks 18 are installed at the set position, and then the filter plate 19 is placed so that the filter plate 19 abuts against the inner wall of the drain ditch 2. Then the water carrying the dead bodies of pests will flow toward the position of the filter plate 19, pass through the filter plate 19, and be discharged through the drain trough, while the dead bodies of pests will be blocked by the filter plate 19 and gathered in the drain ditch 2 near the filter plate 19, and then collected and processed centrally.

[0045] Embodiment 2 In order to better prevent the migration of pests, on the basis of Example 1, when preventing pests such as cotton bollworms and cutworms from migrating to immature farmland, the attractant is sent into the adding pipe 8 through the first joint, and the attractant is discharged into the agent tank 6 through the setting of the dosing nozzle 9. The pests are attracted to enter the V-shaped groove 1 through the odor generated by the attractant. The V-shaped groove 1 is observed at regular intervals, for example, every two days. When the number of pests entering the V-shaped groove 1 is large enough, the pests can be cleaned up in a concentrated manner.

[0046] Among them, it is necessary to add that in order to improve work efficiency, discover pest disasters in time, and facilitate the observation of pest blocking conditions, monitoring equipment can also be set near the V-shaped groove 1 to monitor the V-shaped groove in real time, and record the activities of pests in the farmland in real time. At the same time, an alarm device can be connected. When the number of pests in the V-shaped groove 1 is detected to increase, the alarm can be activated to notify the staff to come and deal with it, reducing the workload of the staff. Through data analysis of the monitoring system, the trend and law of pest disasters can be discovered, and farmers can be warned in advance to take measures to prevent the spread and damage of pests.

[0047] Embodiment 3 like Figures 9 to 12 As shown, in order to improve the cleaning effect of insect corpses and avoid the accumulation of insect corpses, on the basis of Example 1, it is optional to further include a return-shaped tube 21, a third joint 22, a top shell 23 and a swinging part. The return-shaped tube 21 is fixedly installed at the lower part of the multiple arched bamboo frames 3, and the output end of the return-shaped tube 21 is detachably connected to the second joint 16. The third joint 22 is fixedly installed at the input end of the return-shaped tube 21. A plurality of top shells 23 are symmetrically arranged at equal distances on the upper part of the drainage ditch 2. The top shell 23 is fixedly connected to the return-shaped tube 21, and the multiple top shells 23 on both sides are staggered with each other. A plurality of swinging parts are installed on the return-shaped tube 21, and the multiple swinging parts are located at the lower part of the multiple top shells 23.

[0048] Specifically, when there are too many insects accumulated in the V-shaped groove 1, the water source is disconnected from the second joint 16, and then the water source is connected to the third joint 22. At this time, one end of the return pipe 21 is connected to the second joint 16, and water is discharged into the return pipe 21. The water continuously flows in the return pipe 21, so that the swinging part swings, thereby increasing the range of water spraying and improving the cleaning efficiency.

[0049] The above, such as Figures 10 to 12 As shown, the swing part includes a mounting frame 24, a transmission shaft 25, a passive blade 26, a driving bevel gear 27, a driven bevel gear 28, a drive shaft 29, a rotating disk 30, a toggle column 31, a swing frame 32, a slide 33, a second nozzle 34 and a water inlet pipe 35. A plurality of mounting frames 24 are fixedly mounted on the return tube 21. The plurality of mounting frames 24 are located at the lower part of the plurality of top shells 23. A transmission shaft 25 is rotatably mounted on each mounting frame 24. The end of each transmission shaft 25 is fixedly mounted with a plurality of passive blades 26 at equal angles in a circular shape. The passive blades 26 are located in the return tube 21. The other end of each transmission shaft 25 is fixedly mounted with a driving bevel gear 27. Each mounting frame A driven bevel gear 28 is rotatably installed inside 24, and the driven bevel gear 28 is meshed with the driving bevel gear 27. A driving shaft 29 is rotatably installed on each mounting frame 24, and the driving shaft 29 is fixedly connected to the driven bevel gear 28. A rotating disk 30 is fixedly installed at both ends of each driving shaft 29, and a toggle column 31 is eccentrically and fixedly installed on each rotating disk 30. A swing frame 32 is rotatably installed on each mounting frame 24, and slide grooves 33 are provided on both sides of each swing frame 32. The slide grooves 33 are slidably connected to the toggle column 31. A second nozzle 34 is fixedly installed on each swing frame 32, and a water inlet pipe 35 is connected between each second nozzle 34 and the drain pipe 13.

[0050] Specifically, when water flows in the return pipe 21, the water will drive the transmission shaft 25 to rotate under the action of the passive blades 26, and the transmission shaft 25 drives the active bevel gear 27 to rotate automatically, and the active bevel gear 27 drives the driven bevel gear 28 to rotate automatically, thereby driving the drive shaft 29 to rotate, and the drive shaft 29 drives the rotating disk 30 to rotate, and the rotating disk 30 drives the toggle column 31 to rotate around the axial position of the rotating disk 30. At this time, the toggle column 31 and the slide groove 33 produce relative sliding, thereby pushing the swing frame 32 to swing back and forth, thereby driving the second nozzle 34 to swing. At this time, the second nozzle 34 is turned on, and water will enter the second nozzle 34 from the drainage pipe 13 through the setting of the water inlet pipe 35, and then be sprayed out.

[0051] It should be added that, since the second nozzle 34 has a certain range of movement, water can more easily reach the depth of the V-shaped groove 1 and fully cover all corners of the V-shaped groove 1. Moreover, since the ambient humidity in the V-shaped groove 1 is relatively high, the second nozzle 34 with a certain range of movement can also spray away some impurities that are not easily washed away by water, thereby improving the cleaning efficiency.

[0052] Embodiment 4 On the basis of the first embodiment, this embodiment further discloses a method for blocking the migration of pests at the boundary of farmland, using the above-mentioned device for blocking the migration of pests at the boundary of farmland, including the following steps: The first step is isolation. In order to prevent the blocking agent from contaminating the soil, an isolation film is laid on the V-shaped ditch 1 to separate the agent from the soil. The second step is to install the agent groove 6. According to the length of the V-shaped groove 1, a suitable agent groove 6 is set, and then the agent groove 6 is installed at the bottom of the V-shaped groove 1. When it is necessary to kill the pests entering the V-shaped groove 1, it is also necessary to add agents into the agent groove 6. The setting of the agent groove 6 can prevent the agent from falling into the V-shaped groove 1, thereby reducing the risk of the agent infiltrating into the soil and avoiding pollution. The third step is installation. At this time, the arched bamboo frame 3 is installed. In order to improve the stability of the arched bamboo frame 3, the connecting plate 5 needs to be installed, and then the mounting plate 7 is installed. Then, the adding pipe 8 is installed at the bottom of the plurality of mounting plates 7 through the setting of the upper fixing ring 11 and the lower fixing ring 12; The fourth step is laying. In order to prevent rainwater from affecting the reagent tank 6, a plastic film 4 needs to be laid on the arched bamboo frame 3, and there is a certain gap between the edge of the plastic film 4 and the ground. When pests in the highly mature farmland migrate to the less mature farmland, the pests will enter the V-shaped groove 1 through the gap between the plastic film 4 and the ground; The fifth step is to add, connect the pipeline for outputting the agent with the first joint 10, and then inject the agent into the adding pipe 8 through the setting of the first joint 10, and then through the setting of the dosing nozzle 9, the agent entering the adding pipe 8 will be discharged and stored in the agent tank 6. After adding the agent, close the first joint 10, and then disconnect the pipeline for outputting the agent from the first joint 10, so that the pests entering the V-shaped groove 1 are killed by the agent, and the migration of the pests is prevented from the root. Compared with the method of spraying pesticides in the prior art, the insecticide effect is improved; Step 6: cleaning. After a period of time, the agent in the agent tank 6 loses its effect, and a large number of dead insects have accumulated in the V-shaped groove 1. At this time, the dead insects need to be cleaned up. At this time, the water source is connected to the second joint 16, and the water enters the connecting pipe 15 and enters the two drainage pipes 13 at the same time through the connecting pipe 15. When the water enters the connecting pipe 15, the water spray head 17 is started. Due to the inclined arrangement of the water spray head 17, the dead insects in the V-shaped groove 1 can be continuously flushed and flushed into the drainage ditch 2. The seventh step is collection. When water flushes the V-shaped groove 1 and carries the dead insects into the drain ditch 2, the two corresponding placement racks 18 are installed at the set position, and then the filter plate 19 is placed so that the filter plate 19 abuts against the inner wall of the drain ditch 2. Then the water carrying the dead insects will flow toward the position of the filter plate 19, pass through the filter plate 19, and be discharged through the drain trough. The dead insects will be stopped by the filter plate 19 and gathered in the drain ditch 2 near the filter plate 19, and then they will be collected and processed centrally.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
