Description

Technical Field

[0001] This invention relates to the field of pest control technology in grain storage, specifically to a multi-point controlled grain storage pest control system and its control method. Background Technology

[0002] As the main equipment for grain storage, the quality of grain storage depends on the quality of the storage environment. Among these factors, pest control is particularly important in grain storage.

[0003] Currently, the control of pests in grain warehouses mostly involves purging with nitrogen to dilute oxygen and balancing the storage temperature to suppress pests. However, this method of control is often short-lived and usually requires multiple nitrogen purging operations during the grain storage period to achieve the goal of suppressing pests. Therefore, in order to save costs, some grain warehouses also choose to use pesticides to suppress or eliminate pests.

[0004] Patent application CN201910341633.1 in the patent database discloses a device for controlling stored grain pests using Artemisia argyi essential oil. It involves installing a partition plate at the bottom of the grain storage silo, with an essential oil chamber below the partition plate. An essential oil release component is installed on the partition plate, and the Artemisia argyi essential oil is used to control pests inside the grain storage silo. However, this method has two drawbacks. First, it requires a specific structure for the grain storage silo to support the pest control work, making it unsuitable for some existing grain storage silos. Second, since the release of Artemisia argyi essential oil is completed at the bottom of the grain storage silo, the pest control effect will decrease when the grain storage silo is relatively high.

[0005] If an insertion method is used to control pests at different depths in a grain warehouse, such as using a straight rod / tube to deliver the pesticide to the area to be controlled, when the area to be controlled is deep (e.g., more than 5 meters), if the diameter of the straight rod / tube is large, the insertion work will be more difficult. If the diameter of the straight rod / tube is reduced, its own strength will be insufficient, and it will still not be able to accurately deliver the pesticide to the required depth. Summary of the Invention

[0006] To address the technical problems existing in the background art, the present invention provides a multi-point deployment-type grain warehouse pest control system and its control method.

[0007] The technical solution of this invention is as follows:

[0008] This invention first provides a multi-point deployment-type grain warehouse pest control system, including a controller and a deployment device that is connected to and controlled by the controller. By controlling the operation of the deployment device through the controller, the deployment work at multiple points inside the grain warehouse can be completed, thereby completing the pest control work. The structure of the control system (the above-mentioned multi-point deployment-type grain warehouse pest control system) will be described in detail below.

[0009] As one of the core technical concepts of this invention, the control device includes a column and a drilling mechanism at its front end. The column also contains an insect-repellent phosphate spraying mechanism. The drilling mechanism includes a drilling drive motor and a conical drill bit connected to it. The outer ring of the drill bit is provided with spiral blades. The outer ring of the rear end of the column has several guide vanes to prevent it from rotating with the drill bit. The rear end of the column also has spray holes. The insect-repellent phosphate spraying mechanism includes a storage cylinder and nozzles corresponding to the spray holes. The nozzles are connected to the storage cylinder via a spray pump. Both the drilling drive motor and the spray pump are communicatively connected to a controller and can be controlled by the controller. Based on the above structure, the drilling mechanism... The system can drive the control device to penetrate into the grain, and spray insecticide phosphate at the target location through the insecticide phosphate spraying mechanism. A certain pest control area is formed centered on the target location. Finally, through the coordinated operation of the drilling mechanism and the insecticide phosphate spraying mechanism, the control work of multiple points (multiple pest control areas) inside the grain warehouse is completed, thereby completing the overall pest control work inside the grain warehouse. The control device is designed to carry out pest control work after the grain is stored in the grain warehouse, so that the control device can be used for pest control work in most grain warehouses. Moreover, when the grain warehouse has different specifications, the operation of the control device can be manually controlled by the controller as needed to carry out multi-point control, which significantly improves the pest control effect.

[0010] As another core technical concept of the present invention, the control device further includes a reversing mechanism capable of driving the drilling mechanism to change the drilling direction. Specifically, the reversing mechanism includes a connecting plate coaxially rotatably disposed inside the column, and a rotary drive motor capable of driving the plate to rotate. A reversing block is slidably disposed on the front end face of the connecting plate, and a sliding drive motor capable of driving the reversing block to slide is disposed inside the reversing block. The front end of the column has an opening, and a straightening mechanism is disposed within the opening. The straightening mechanism includes a rotating ring rotatably disposed within the opening, and a rubber ring disposed within the inner ring of the rotating ring. It also includes a reversing rod, the rear end of which passes through a rubber ring and is hinged to the reversing block. The drill bit is rotatably located at the front end of the reversing rod, and the drilling drive is located inside the front end of the reversing rod. Both the sliding drive and the rotary drive are communicatively connected to the controller and can be controlled by the controller. Based on the above structure, the orientation of the front end of the reversing rod can be changed at multiple angles through the cooperation of the sliding drive and the rotary drive, thereby realizing the adjustment of the drilling direction of the drilling mechanism, preventing large deviations in the control position during the movement of the control device, and ultimately making the control work at the target position more accurate and reliable.

[0011] As described above, in a preferred embodiment of the multi-point deployment grain warehouse pest control system, the reversing mechanism further includes a turntable coaxially rotatable inside the column. The rotary drive is located on one side of the turntable and can drive the turntable to rotate. A telescopic drive is also provided on the front side of the turntable along the column axis. The end of the telescopic drive away from the turntable is connected to a connecting plate. The connecting plate is configured to rotate under the drive of the turntable and move along the column axis under the drive of the telescopic drive. Based on this structure, on the one hand, the telescopic mechanism drives the reversing rod to extend and retract, which enables the drilling mechanism to better complete the drilling operation. On the other hand, the telescopic mechanism drives the reversing rod to extend and retract, which causes the length of the reversing rod relative to both sides of the reversing mechanism to change, thereby enabling the drilling mechanism to better complete the reversing operation under the action of the reversing mechanism.

[0012] Furthermore, to prevent the reversing mechanism from being affected by the insecticide spraying mechanism (due to moisture, chemical corrosion, etc.), a partition is provided inside the column between the reversing mechanism and the insecticide spraying mechanism.

[0013] To enable the turntable to rotate smoothly under the action of the rotary drive motor, and to increase the controllability of the rotation angle of the turntable under the action of the rotary drive motor, the rotary drive motor includes a first body fixed to one side of the turntable, and a rotary drive wheel driven by the first body. The inner ring of the column is provided with a toothed ring corresponding to the position of the rotary drive wheel, and the rotary drive wheel is a gear structure that meshes with the toothed ring.

[0014] To enable the commutator block to slide smoothly under the action of the sliding drive motor, and to increase the controllability of the sliding distance of the commutator block under the action of the sliding drive motor, a groove passing through its center is provided on the front end surface of the connecting plate. The commutator block is slidably disposed in the groove. The sliding drive motor includes a second body fixed inside the commutator block and a sliding drive wheel driven to rotate by the second body. A rack is provided in the groove along its setting direction. The sliding drive wheel is a gear structure that meshes with the rack.

[0015] As described above, in order to facilitate the monitoring of the location of the control device and thus achieve precise control of the target location, the column is also equipped with a positioning element that communicates with the controller.

[0016] To make it easier to remove the control device from inside the grain after it has been deployed, the prevention and control system also includes a traction rope connected to the tail end / guide wing of the column.

[0017] The present invention also provides a method for pest control. Based on the above-described control system, the control method (the above-described method for pest control) includes at least the following steps:

[0018] S1. Preparation;

[0019] The controller includes a display screen, a processor, and input keys. The specific steps are as follows:

[0020] S1.1 Input the inner diameter and depth data of the grain silo to be controlled into the controller using the input key;

[0021] S1.2 The processor generates two two-dimensional images of the grain silo on the display screen in proportion to the input inner diameter and depth data of the grain silo. One two-dimensional image is a square image representing the depth of the grain silo, and the other two-dimensional image is a circular image representing the inner diameter of the grain silo.

[0022] S1.3 The processor determines whether multiple longitudinal control is needed based on the input grain warehouse inner diameter data. If not, a first marker point is generated at the center of the circular image. If so, multiple first marker points are generated in the circumferential array within the circular image, and one of the first marker points is selected to mark its actual distance from the center of the circular image.

[0023] S1.4 The processor determines whether multi-point control is needed based on the input grain warehouse depth data. If not, a second marker point is generated at the center of the square image. If so, multiple second marker points are generated linearly along the vertical center line of the square image.

[0024] S2, deployment;

[0025] Based on the location of the grain silo corresponding to the first marker point, the control device is manually placed. Based on the depth of the grain silo corresponding to the second marker point and the feedback information from the positioning element, the drilling drive, sliding drive, rotary drive and spraying pump are controlled to complete the control and prevention of pests inside the grain silo.

[0026] In the pest control method described above, if there are multiple first and second marker points in step S2, the specific deployment method is as follows:

[0027] AS2.1 The operator places the control device inside the grain warehouse at the position corresponding to one of the first marker points, and inserts the drilling mechanism downwards into the grain.

[0028] AS2.2 The drilling drive motor moves to drive the control device to drill downwards. During the drilling process, the controller controls the sliding drive motor and the rotary drive motor to move according to the feedback information from the positioning element until the control device reaches the grain silo depth position corresponding to the second mark point at the top.

[0029] AS2.3, the spray pump operates for a preset time to spray insecticide phosphorus;

[0030] AS2.4 The drilling drive motor moves to drive the control device to continue drilling downwards. During the drilling process, the controller controls the sliding drive motor and the rotary drive motor to move according to the feedback information from the positioning element until the control device reaches the grain silo depth position corresponding to the next second marker point.

[0031] AS2.5, Execute step AS2.3 once;

[0032] AS2.6 Repeat steps AS2.4-AS2.5 until the control work of the grain warehouse depth position corresponding to the second mark point at the bottom is completed;

[0033] AS2.7 The control device is manually pulled out using a traction rope;

[0034] AS2.8 Place the control device at the next first marker point and insert the drilling mechanism downwards into the grain;

[0035] AS2.9, Execute steps AS2.2-AS2.7 once;

[0036] AS2.10. Repeat steps AS2.8-AS2.9 until the longitudinal control work of all grain warehouse locations corresponding to the first marker points is completed.

[0037] In the pest control method described above, the specific method for generating the first marker point in step S1 is as follows:

[0038] If the inner diameter of the grain silo is less than 3m, the first marker point is generated only at the center of the circular image. If the inner diameter of the grain silo is greater than or equal to 3m, multiple first marker points are generated in a circular array within the circular image. The number of first marker points generated is the same as the radius of the grain silo, and the radius of the grain silo is a value in "m". If the radius of the grain silo is not an integer, the number of first marker points generated is calculated by rounding the radius of the grain silo to the nearest integer. This ensures that even when the diameter of the grain silo is large, the overall pest control work inside the grain silo can still be completed through multi-vertical deployment.

[0039] The beneficial effects of this invention are as follows:

[0040] (1) The drilling mechanism can drive the control device to drill into the grain, and the insecticidal phosphorus spraying mechanism can spray insecticidal phosphorus at the target location, forming a certain pest control area centered on the target location. Finally, through the coordinated operation of the drilling mechanism and the insecticidal phosphorus spraying mechanism, the control work of multiple points inside the grain warehouse is completed, thereby completing the pest control work inside the grain warehouse as a whole and improving the pest control effect.

[0041] (2) The control device is used to control pests after grain is stored in the granary, so that the control device can be used in the pest control work of most granaries.

[0042] (3) When the specifications of the grain warehouse are different, the operation of the control device can be controlled manually through the controller as needed to carry out multi-point control, which significantly improves the pest control effect.

[0043] (4) By cooperating with the sliding drive and the rotary drive, the orientation of the front end of the reversing rod can be changed at multiple angles, thereby adjusting the drilling direction of the drilling mechanism, preventing large deviations in the control position during the movement of the control device, and ultimately making the control work of the target position more accurate and reliable.

[0056] Example

[0057] This embodiment first provides a multi-point deployment-type grain warehouse pest control system, including a controller and a deployment device that is connected to and controlled by the controller. By controlling the operation of the deployment device through the controller, the deployment work of multiple points inside the grain warehouse can be completed, thereby completing the pest control work. The structure of the control system will be described in detail below.

[0058] In this embodiment, combined with Figure 1 and Figure 2 The deployment device includes a column cylinder 1 and a drilling mechanism 2 at its front end. The column cylinder 1 is also equipped with an insect-repellent phosphorus spraying mechanism 5. The column cylinder 1 is configured to drill into the grain under the drive of the drilling mechanism 2, and complete the insect-repellent phosphorus spraying deployment work at the target location through the insect-repellent phosphorus spraying mechanism 5.

[0059] Combination Figure 6The drilling mechanism 2 includes a drilling drive 23 and a conical drill bit 21 connected to it. The outer ring of the drill bit 21 is also provided with a spiral blade 22. The outer ring of the rear end of the column cylinder 1 is provided with several guide wings 8 that can prevent it from rotating with the drill bit 21. The drilling drive 23 drives the drill bit 21 to move, and then the drilling work of the control device is realized under the action of the spiral blade 22.

[0060] Combination Figure 7 Regarding the structure of the insecticide spraying mechanism 5, the rear end of the column 1 is also provided with a spraying hole. The insecticide spraying mechanism 5 includes a storage cylinder 51 located inside the column 1, and nozzles 54 corresponding to the spraying holes. The nozzles 54 are connected to the spraying pump 52 via a connecting pipe 53, and then connected to the storage cylinder 51 via the spraying pump 52. The drilling drive 23 and the spraying pump 52 are both connected to the controller and can be controlled by the controller. Based on the above structure, the operation of the drilling mechanism 2 can drive the entire deployment device to drill into the grain, and the insecticide spraying machine can then spray the insecticide. Structure 5 completes the spraying of insecticidal phosphorus at the target location, forming a certain pest control area centered on the target location. Finally, through the coordinated operation of drilling mechanism 2 and insecticidal phosphorus spraying mechanism 5, the control work at multiple points inside the grain warehouse is completed, thereby completing the overall pest control work inside the grain warehouse. The control device is designed to carry out pest control work after grain is stored in the grain warehouse, so that the control device can be applied to the pest control work of most grain warehouses. Moreover, when the grain warehouse has different specifications, the operation of the control device can be manually controlled by the controller as needed to carry out multi-point control, which significantly improves the pest control effect.

[0061] In this embodiment, the deployment device also includes a reversing mechanism 3 that can drive the drilling mechanism 2 to change the drilling direction. The reversing mechanism 3 can drive the drilling mechanism 2 to adjust the drilling direction, thereby ensuring the accurate deployment of the target position.

[0062] Combination Figures 3-5The reversing mechanism 3 includes a connecting disc 35 coaxially rotatably disposed inside the column cylinder 1, and a rotary drive 33 capable of driving its rotation. A reversing block 36 is slidably disposed on the front end face of the connecting disc 35, and a sliding drive 37 capable of driving its sliding is disposed inside the reversing block 36. The front end of the column cylinder 1 has an opening, and a straightening mechanism 4 is disposed within the opening. The straightening mechanism 4 includes a rotating ring 41 rotatably disposed within the opening, and a rubber ring 42 disposed on the inner ring of the rotating ring 41. The reversing mechanism 3 also includes a reversing rod 38, the rear end of which passes through the rubber ring 42 and is hingedly connected to the reversing block 36. The reversing rod 38 and the reversing block 36 are connected... The rotation axis of one hinged end is perpendicular to the sliding direction of the reversing block 36. The drill bit 21 is rotatably mounted at the front end of the reversing rod 38, and the drilling drive 23 is located inside the front end of the reversing rod 38. The sliding drive 37 and the rotary drive 33 are both connected to the controller and can be controlled by the controller. Based on the above structure, through the cooperation of the sliding drive 37 and the rotary drive 33, the orientation of the front end of the reversing rod 38 can be changed at multiple angles, thereby realizing the adjustment of the drilling direction of the drilling mechanism 2, preventing large deviations in the control position during the movement of the control device, and ultimately making the control work of the target position more accurate and reliable.

[0063] To enable the commutator block 36 to slide smoothly under the action of the sliding drive 37, and to increase the controllability of the sliding distance of the commutator block 36 under the action of the sliding drive 37, a groove passing through its center is provided on the front end face of the connecting plate 35. The commutator block 36 is slidably disposed in the groove. The sliding drive 37 includes a second body fixed inside the commutator block 36 and a sliding drive wheel driven to rotate by the second body. A rack is provided in the groove along its setting direction. The sliding drive wheel is a gear structure that meshes with the rack.

[0064] In a preferred embodiment of this invention, the reversing mechanism 3 further includes a fixing ring 31 coaxially fixed to the inner ring of the column cylinder 1, and a turntable 32 coaxially rotatable inside the column cylinder 1 via the fixing ring 31. The rotary drive 33 is located on one side of the turntable 32 and can drive the turntable 32 to rotate. A telescopic drive 34 is also provided on the front side of the turntable 32 along the axis of the column cylinder 1. The end of the telescopic drive 34 away from the turntable 32 is connected to a connecting plate 35. The connecting plate 35 is configured to rotate under the drive of the turntable 32 and move along the axis of the column cylinder 1 under the drive of the telescopic drive 34. Based on this structure, on the one hand, the telescopic mechanism drives the reversing rod 38 to extend and retract, which can drive the drilling mechanism 2 to complete the drilling operation better. On the other hand, the telescopic mechanism drives the reversing rod 38 to extend and retract, which can change the length of the reversing rod 38 relative to both sides of the reversing mechanism 3, thereby enabling the drilling mechanism 2 to complete the reversing operation better under the action of the reversing mechanism 3.

[0065] To enable the turntable 32 to rotate smoothly under the action of the rotary drive 33, and to increase the controllability of the rotation angle of the turntable 32 under the action of the rotary drive 33, the rotary drive 33 includes a first body fixed to one side of the turntable 32, and a rotary drive wheel driven by the first body. The inner ring of the column 1 is provided with a toothed ring corresponding to the position of the rotary drive wheel, and the rotary drive wheel is a gear structure that meshes with the toothed ring.

[0066] In this embodiment, to prevent the reversing mechanism 3 from being affected by the insecticidal phosphorus spraying mechanism 5 (affected by moisture, chemical corrosion, etc.), a partition 6 is also provided inside the column 1 at the position between the reversing mechanism 3 and the insecticidal phosphorus spraying mechanism 5.

[0067] Furthermore, in order to facilitate the monitoring of the location of the control device and thus achieve precise control of the target location, the column 1 is also equipped with a positioning element 7 that is connected to the controller.

[0068] In a preferred embodiment, two partition plates 6 are provided between the reversing mechanism 3 and the insect-repellent phosphorus spraying mechanism 5, and the positioning element 7 is located between the two partition plates 6.

[0069] Furthermore, to make it easier to remove the control device from inside the grain after the control device is deployed, the prevention and control system also includes a traction rope connected to the tail end / guide wing 8 of the column 1.

[0070] The present invention also provides a method for pest control, based on the above-described control system, the method comprising at least the following steps:

[0071] S1. Preparation;

[0072] The controller includes a display screen, a processor, and input keys. The specific steps are as follows:

[0073] S1.1 Input the inner diameter R (here, the inner diameter is considered as the grain silo diameter, in meters) and depth H (in meters) of the grain silo to be controlled into the controller via the input key;

[0074] S1.2 The processor generates two two-dimensional images of the grain silo on the display screen in proportion to the input inner diameter and depth data. One two-dimensional image is a square image representing the depth of the grain silo with a height of h. The other two-dimensional image is a circular image representing the inner diameter of the grain silo with a radius of r.

[0075] S1.3. Based on the input grain silo inner diameter data R, the processor determines whether multiple longitudinal control points are needed. If not, a first marker point is generated at the center of the circular image. If so, multiple first marker points are generated in a circular array within the circular image, and one of the first marker points is selected to mark its actual distance from the center of the circular image. The specific method for generating the first marker point is as follows:

[0076] If the inner diameter R of the grain silo is less than 3m, then only one first marker point is generated at the center of the circular image;

[0077] If the inner diameter R of the grain silo is greater than or equal to 3m, multiple first marker points are generated in a circular array within the circular image. The specific number of first marker points generated is the same as the grain silo radius (i.e., R / 2), and the grain silo radius is a value in "m". If the grain silo radius is not an integer, the number of first marker points generated is calculated by rounding the grain silo radius to the nearest integer. At the same time, the distance on the map between any first marker point and the center of the circular image is r / 2, but the actual distance marked is R / 4. This ensures that even when the grain silo diameter is large, the overall pest control work inside the grain silo can still be completed through multi-vertical control.

[0078] S1.4. Based on the input grain warehouse depth data H, the processor determines whether multi-point control is required. If not, a second marker point is generated at the center of the square image. If so, multiple second marker points are generated linearly along the vertical centerline of the square image. The specific generation method of the second marker points is as follows:

[0079] If the depth H of the grain silo is less than 5m, then only one second marker point is generated at the center of the square image;

[0080] If the inner diameter of the grain silo is greater than or equal to 5m, multiple second marker points are generated linearly along the vertical center line of the square image. The distance between the topmost second marker point and the top edge of the square image is 2h / H, the distance between two adjacent second marker points is 1.5h / H, and the distance between the bottommost second marker point and the bottom edge of the square image is less than 1.5h / H. This ensures that even when the grain silo is deep, the overall pest control work inside the grain silo can still be completed through a multi-point control method along a single vertical direction.

[0081] S2, deployment;

[0082] Based on the location of the grain silo corresponding to the first marker point, the control device is manually placed. Based on the depth of the grain silo corresponding to the second marker point and the feedback information from the positioning element 7, the drilling drive 23, sliding drive 37, rotary drive 33, and spraying pump 52 are controlled to complete the control and prevention of pests inside the grain silo. Specifically, this includes the following situations:

[0094] B. If there is one first marker point and one second marker point, then the specific deployment method is as follows;

[0095] BS2.1. The operator places the control device in the grain warehouse at the position corresponding to the first mark point, and inserts the drilling mechanism 2 downward into the grain.

[0096] BS2.2, The drilling drive 23 drives the control device to drill downwards. During the drilling process, the controller controls the sliding drive 37 and the rotary drive 33 to operate according to the feedback information from the positioning element 7, until the control device reaches the grain silo depth position corresponding to the second marker point.

[0097] BS2.3, spray pump 52 operates within the preset time to spray insecticide phosphate;

[0098] BS2.4 The control device is manually pulled out using a traction rope;

[0099] C. If there are multiple first markers and only one second marker, then the specific deployment method is as follows:

[0100] CS2.1, The operator places the control device inside the grain warehouse at the position corresponding to one of the first marker points, and inserts the drilling mechanism 2 downward into the grain;

[0101] CS2.2, The drilling drive motor 23 drives the control device to drill downwards. During the drilling process, the controller controls the sliding drive motor 37 and the rotary drive motor 33 to operate according to the feedback information of the positioning element 7, until the control device reaches the grain silo depth position corresponding to the second mark point.

[0102] CS2.3 and spray pump 52 operate within the preset time to spray insecticide phosphate;

[0103] CS2.4, The control device is manually pulled out using a traction rope;

[0104] CS2.5 Place the control device at the next first marker point and insert the drilling mechanism 2 downwards into the grain;

[0105] CS2.6, Execute steps AS2.2-AS2.4 once;
