Description

Technical Field

[0001] This utility model belongs to the field of agricultural pest control technology, specifically relating to an agricultural pest control device. Background Technology

[0002] In agricultural production, pests are a major factor affecting the growth and yield of agricultural plants. Growers need to prevent and control pests and diseases in a timely manner to ensure the normal growth of plants.

[0003] In agricultural pest control devices, wind-suction insecticidal lamps attract insects with light and trap and kill them by sucking them in with strong airflow. This pollution-free and residue-free pest control method has significant advantages and is widely used, especially in the cultivation of pollution-free green food.

[0004] In existing technologies, suction-type insecticidal lamps temporarily store insect carcasses in a collection container at the bottom. However, this requires frequent cleaning by staff, increasing their workload. Some suction-type lamps reduce this cleaning frequency by increasing the volume of the collection container. However, the cleaning frequency is also affected by the decay of the insect carcasses inside. Simply increasing the volume reduces airflow speed and disperses airflow, resulting in poor drying of the insect carcasses. Further reducing the cleaning frequency leaves the container partially empty while the insect carcasses inside have already decayed. This not only makes cleaning the collection container more difficult but also harms the growth of crops around the suction-type insecticidal lamp. Utility Model Content

[0005] This invention provides a pest control device for farmland, which can effectively reduce the frequency of cleaning up insect carcasses.

[0006] This utility model provides the following technical solution: a farmland pest control device, comprising a wind-suction type insect-killing lamp body and a wind suction cylinder, wherein the bottom end of the wind suction cylinder is open;

[0007] The farmland pest control device also includes a drying zone, which includes a diversion pipe and two drying pipes that are alternately connected to the air suction cylinder;

[0008] An emission path regulating mesh plate is hinged inside the diversion pipe to regulate the emission path of insect carcasses;

[0009] Two air-drying cut-off plates are respectively hinged inside the two air-drying pipes to adjust the opening and closing of the bottom opening of the air-drying pipes;

[0010] A large-volume container is installed at the bottom of the drying area to store a large number of insect carcasses.

[0011] The bottom end of the air suction cylinder is fixedly connected to a connecting sleeve, which is fixedly connected to the diverter pipe, and the bottom end of the connecting sleeve extends into the diverter pipe.

[0012] The bottom end of the connecting sleeve is provided with an arc-shaped groove, and the bottom edge of the arc-shaped groove matches the rotation path of the discharge path adjustment mesh plate.

[0013] The side walls of both the diversion pipe and the drying pipe are fixedly connected with protective covers.

One end of the connecting shaft extends into the protective cover.

[0015] The large-volume container box has a detachable pull-out box inside.

[0016] Both the large-volume container and the pull-out box have corresponding exhaust screens installed on their side walls.

[0017] The beneficial effects of this utility model are as follows: by combining the diversion pipe, the drying pipe and the large-volume container to form a large insect carcass holding space, the diversion pipe and the drying pipe with smaller internal space serve as drying functional areas, which can improve the drying effect of airflow on insect carcasses.

Detailed Implementation

[0025] Please see Figures 1-5 The present invention provides the following technical solution: a farmland insect control device, comprising a wind-suction insect control lamp body 1 and a wind suction cylinder 11, wherein the bottom end of the wind suction cylinder 11 is open;

[0026] The farmland pest control device also includes a drying zone 2, which includes a diversion pipe 21 and two drying pipes 22 that are alternately connected to the air suction cylinder 11.

[0027] The discharge path adjustment mesh plate 3 is hinged in the diversion pipe 21 to adjust the discharge path of the insect carcasses.

[0028] Two air-drying intercepting plates 31 are respectively hinged inside two air-drying pipes 22 to adjust the opening and closing of the bottom opening of the air-drying pipes 22.

[0029] Large-volume container 4 is installed at the bottom of the drying area 2 to store large quantities of insect carcasses.

[0030] In this implementation scheme: In the initial state, the discharge path adjustment mesh plate 3 tilts to one side, contacting the inner wall of the connecting sleeve 12. The wind-suction insecticidal lamp body 1 attracts insects with its light and is sucked into the air suction cylinder 11 by the strong airflow generated by the fan. Subsequently, under the action of the strong airflow, the insects are blown into the diversion pipe 21 and one of the drying pipes 22, where they are trapped and killed. Under the continuous action of the wind, the insect carcasses are gradually dried. During the process, the dried insect carcasses continuously accumulate in the diversion pipe 21 and the drying pipe 22. The drying interception plate 31 seals the bottom opening of the drying pipe 22, preventing the insect carcasses from falling into the large-volume container 4. The large-volume container 4 has a larger internal volume. The space inside the drying duct 22 is smaller. With the airflow limited at the suction nozzle 11, the air velocity inside the drying duct 22 is faster, resulting in better drying of the insect carcasses. After one switching cycle, the controller controls the drive mechanism to swing the discharge path adjustment mesh 3 to the other side. The subsequently sucked-in insects enter another drying duct 22. At this time, some live insects and undried insect carcasses still remain in the previous drying duct 22. The drying trapping plate 31 continues to seal the bottom opening of the drying duct 22, continuously trapping and killing the insects. Some airflow still passes through the discharge path adjustment mesh 3 and is blown into the previously used drying duct. In pipe 22, live insects and undried insect carcasses are continuously dried until a work switching cycle is completed. Then, the controller controls the drive mechanism to rotate the drying trap 31 at the previous drying pipe 22 downwards. The dried insect carcasses enter the large-volume container 4 and the pull-out box 41 under the influence of airflow. After a certain period, the controller controls the downward-rotating drying trap 31 to reset, and then controls the discharge path adjusting mesh 3 to swing and reset, switching the insect intake channel. At this time, another drying pipe 22 repeats the insect trapping and drying process. In this working mode, the inhaled insects are continuously dried for at least one cycle. The cycle is switched to ensure that the insects have enough time to dry. By optimizing the drying environment and drying time of the insects, the drying effect on the insect carcasses is improved, the decay time of the insect carcasses is extended, and the storage time of the insect carcasses is increased. With the diversion pipe 21, the drying pipe 22 and the large volume container 4 forming a larger insect carcass holding space, the cleaning frequency of the device can be effectively reduced. In actual installation, the device is fixed by a bracket or suspension mechanism and connected to the power supply through an electric wire. The connecting shaft 32 can be driven by a drive motor. The opening and closing of the wind suction insect killing lamp body 1 and the rotation of the connecting shaft 32 are controlled by the controller of the wind suction insect killing lamp body 1.

[0031] A connecting sleeve 12 is fixedly connected to the bottom end of the air suction cylinder 11. The connecting sleeve 12 is fixedly connected to the diversion pipe 21, and the bottom end of the connecting sleeve 12 extends into the diversion pipe 21. The connecting sleeve 12 can serve as a connection structure between the air suction cylinder 11 and the diversion pipe 21.

[0032] The bottom end of the connecting sleeve 12 is provided with an arc-shaped groove 13, and the bottom edge of the arc-shaped groove 13 is matched with the rotation path of the emission path adjustment mesh plate 3. The arc-shaped groove 13 can play a role in making way so that the emission path adjustment mesh plate 3 can rotate smoothly. The edge of the connecting sleeve 12 protrudes to play a positioning role and limit the excessive rotation of the emission path adjustment mesh plate 3.

[0033] Both the diversion pipe 21 and the air drying pipe 22 are fixedly connected to protective covers 23 on their side walls; by setting the protective covers 23, they can serve as the mounting carrier for the drive motor and the transmission mechanism, and protect the drive motor and the transmission mechanism.

[0034] A connecting shaft 32 is fixedly connected to one side of both the emission path adjustment mesh plate 3 and the air drying interception plate 31. The connecting shaft 32 located in the diversion pipe 21 is rotatably connected to the diversion pipe 21, and the connecting shaft 32 located in the air drying pipe 22 is rotatably connected to the air drying pipe 22. One end of the connecting shaft 32 extends into the protective cover 23. By setting the connecting shaft 32, a drive motor can be connected to drive the emission path adjustment mesh plate 3 and the air drying interception plate 31 to rotate. The connecting shaft 32 passes through the side wall of the diversion pipe 21 or the air drying pipe 22 at the corresponding position and extends into the protective cover 23 to connect with the drive motor.

[0035] A pull-out box 41 is detachably connected inside the large-volume container 4; by setting the pull-out box 41, the insect corpses that fall into the large-volume container 4 can be contained. When cleaning the insect corpses, the pull-out box 41 is pulled out of the large-volume container 4, and after cleaning the insect corpses in the pull-out box 41, it is inserted back into the large-volume container 4.

[0036] Both the large volume container 4 and the pull-out box 41 have exhaust nets 42 installed on their side walls. By setting the exhaust nets 42, the air sent into the diversion pipe 21 and the air drying pipe 22 by the air suction cylinder 11 can be discharged to form a complete airflow path. When in use, the air is drawn into the air suction cylinder 11 and blown forward into the diversion pipe 21 and the air drying pipe 22, and then enters the large volume container 4 and the pull-out box 41, and is discharged to the outside through the exhaust nets 42.

[0037] The working principle and usage process of this utility model are as follows: The main body 1 of the wind-suction insect-killing lamp attracts insects with its light, and the insects are sucked into the air suction cylinder 11 by the strong airflow generated by the fan. Then, under the action of the strong airflow, the insects are blown into the diversion pipe 21 and one of the drying pipes 22, where they are trapped and killed. Under the continuous action of the airflow, the insect carcasses are gradually dried. During this process, the dried insect carcasses continuously accumulate in the diversion pipe 21 and the drying pipe 22. After a switching cycle is reached, the controller controls the drive mechanism to swing the discharge path adjustment mesh plate 3 to the other side. The insects sucked in next enter the other drying pipe 22. At this time, there are still some live insects and undried insect carcasses in the previous drying pipe 22, which are still being dried until a working switching cycle is reached. The controller controls the drive mechanism to rotate the drying trap 31 at the previous drying pipe 22 downwards. The dried insect carcasses enter the large-volume container 4 and the pull-out box 41 under the action of airflow. After a certain period of time, the controller controls the downward-rotating drying trap 31 to reset, and then controls the discharge path adjustment mesh 3 to swing and reset, switching the insect's intake channel. At this time, the other drying pipe 22 repeats the work of trapping and drying insects. By optimizing the drying environment and drying time of the insects, the drying effect on the insect carcasses is improved, the decay time of the insect carcasses is extended, and the storage time of the insect carcasses is increased. With the larger insect carcass holding space formed by the diversion pipe 21, the drying pipe 22 and the large-volume container 4, the cleaning frequency of the device is reduced.
