[0002] Forages (such as alfalfa, ryegrass, corn grass, etc.) are an important basis for the development of animal husbandry, and their quality directly affects the efficiency of livestock and poultry breeding. However, during the storage process of forages, they are easily damaged by boring and gnawing, resulting in weight loss and quality reduction. Traditional pest control methods mainly rely on chemical pesticide spraying, which has significant defects in long-term use. With the popularization of the concepts of green agriculture and organic farming, forage pest control devices also avoid using pesticides to protect the environment.

[0042] A cleaning mechanism 4, the cleaning mechanism 4 is fixedly installed on the surface of the connecting shaft 307 for cleaning the surface of the power grid mechanism 5.

[0043] The bottom of the tank body 1 is funnel-shaped, and four biodegradable bag fixing columns 13 are fixedly installed on the surface of the tank body 1 near the bottom for installing biodegradable bags.

[0044] The cleaning mechanism 4 includes a scraper 401, two scraper 401s are symmetrically fixedly installed on the surface of the connecting shaft 307, a scraper rubber strip 402 is fixedly installed on one side of each of the two scraper 401s, and a ring 403 is fixedly installed at the top of the two scraper 401s together.

[0045] The power grid mechanism 5 includes a power grid top plate 501, which is fixedly installed at the bottom of the battery 6 through a pillar. The power grid top plate 501 is fixedly connected to a power grid bottom plate 504 through a power grid 503. A protective plate 502 is fixedly installed on the inner wall of the tank body 1, and the protective plate 502 is adaptively installed with the power grid top plate 501.

[0046] The circular ring 403 is rotatably installed between the protective plate 502 and the power grid top plate 501. The protective plate 502 is used to prevent pests from entering the upper part of the tank body 1 and leaking and killing pests.

[0047] During actual use, the installation method of the tank body 1 can be selected as a hanging type or fixed through a column. The power grid 503 is composed of multiple vertical metal wires. The middle part of the worm 305 meshes with the worm gear 306. The scraping rubber strip 402 is made of insulating material. The device electrical appliances are controlled by a control integration system. A slot is opened at the middle position of the tank body 1 for pests to enter the inside of the tank body 1.

[0048] The working principle of a forage pest control device provided by the present invention is as follows:

[0049] First, the tank body 1 is installed manually in a warehouse where pest control is required, and biodegradable bags are installed on the four degradation bag fixing columns 13.

[0050] Then, the device is powered by the battery 6, and the ultraviolet lamp 7 is started to attract pests to enter the inside of the device through the slot of the tank body 1. Since the ultraviolet lamp 7 is arranged inside the power grid 503, after the pests enter the inside of the tank body 1, they are attracted and collide with the power grid 503. After the power grid 503 electrocutes the pests, the pest corpses fall onto the insect board 21. At the same time, due to the power grid 503 electrocuting the pests, the metal wires of the power grid 503 remain with pest corpses after multiple electrocutions.

[0051] Then, when there are corpses left on the power grid 503 and the insect board 21 after the device has carried out pest control treatment for a period of time, the drive motor 301 is started to drive the insect board shaft 2 to rotate to 45° and then stop. The insect board 21 rotates and opens accordingly to drop the pest corpses into the biodegradable bag below. At this time, the first gear 302 also rotates to drive the toothed plate 303 to descend. The toothed plate 303 also drives the second gear 304 to rotate. A worm 305 is fixedly installed inside the second gear 304. The worm 305 rotates to drive the worm gear 306 to rotate. In this way, the rotation of the worm gear 306 is amplified to 180°. The worm gear 306 drives the connecting shaft 307 to rotate. The scraping plate 401 is fixedly installed on the surface of the connecting shaft 307. Therefore, the scraping plate 401 also rotates 180°. The scraping rubber strip 402 cleans the surface of the power grid 503 to scrape off the pest corpses remaining on the surface of the power grid 503, which also fall into the biodegradable bag below. Then the drive motor 301 resets, and the scraping rubber strip cleans the power grid 503 again and then resets.

[0052] Finally, after the worm board 21 is reset, the odor generated by the corpse below is blocked from entering the environment and is isolated from the environment. After the biodegradable bag is full, it is taken away and replaced manually.

[0053] Compared with the related art, the forage pest control device provided by the present invention has the following beneficial effects:

[0054] By setting up an ultraviolet lamp 7 to attract pests and electrocute them through the power grid 503 to prevent and control pests, by setting up a driving motor 301 to link the insect board 21 to flip and the scraper 401 to clean, the collection of insect corpses and the cleaning of the power grid 503 are integrated to reduce the number of manual interventions, and by setting up the insect board 21, when there are fewer insect corpses, the odor generated in the biodegradable bag can be sealed to prevent harmful effects from entering the environment, and the biodegradable bag fixing column 13 is used to facilitate the replacement of the biodegradable bag to protect the ecological environment and avoid secondary damage to the environment caused by the pest corpses.

[0055] Second embodiment

[0056] Please refer to Figures 6 - 10 Based on the forage pest control device provided by the first embodiment of the present application, the second embodiment of the present application provides another forage pest control device. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0057] Specifically, the forage pest control device provided in the second embodiment of the present application is different in that a closing mechanism 8 is symmetrically fixedly installed on the outer wall of the tank body 1, and the closing mechanism 8 includes a bracket 801, and two of the brackets 801 are symmetrically fixedly installed on the outer wall of the tank body 1, and a rotating shaft 802 is rotatably installed between the two brackets 801, and a motor 803 is fixedly installed on the bottom end of the rotating shaft 802, and the motor 803 is fixedly installed on the outer wall of the tank body 1 through the bracket, and a closing plate 804 is fixedly installed on the surface of the rotating shaft 802, and the two closing plates 804 are adapted to be installed at the groove of the tank body 1.

[0058] A fan mechanism 9 is fixedly installed on the top of the battery 6, and the fan mechanism 9 includes a fan motor 901, and the fan motor 901 is fixedly installed on the top of the battery 6. The output shaft of the fan motor 901 is fixedly connected to a fan blade 902, and a fan housing 903 is provided outside the fan blade 902. The fan housing 903 is connected to a three-way pipe 904, and the three-way pipe 904 passes through the top of the tank body 1 and extends to the outside. The three-way pipe 904 is connected to a core tube 914 through a flange 905. The core tube 914 A core lure tube 906 is rotatably installed on the inner wall, and a lure core of the core lure tube 906 is placed inside. A three-way valve shaft 907 is provided on the surface of the three-way valve shaft 907, and a first switch plate 908 and a second switch plate 909 are fixedly installed on one end of the three-way valve shaft 907. The angle between the first switch plate 908 and the second switch plate 909 is 90°. The surface of the three-way tube 904 is connected to a nozzle 911 through an air blowing pipe 910, and the top of the three-way tube 904 is connected to an annular air outlet pipe 913 through an attractant air supply pipe 912.

[0059] A toggle plate 11 is fixedly mounted on the top of the circular ring 403 . The toggle plate 11 is adapted to be mounted on the first switch plate 908 and the second switch plate 909 . A plurality of vent holes 12 are formed on the surface of the grid top plate 501 .

[0060] Two ultrasonic devices 10 are symmetrically and fixedly installed on the outer wall of the tank body 1 to drive away beneficial insects and prevent them from entering the interior of the tank body 1.

[0061] In actual use, a plurality of holes are provided on the outer side of the annular air outlet pipe 913 for discharging the trapping agent gas, the air blowing pipe 910 is adapted and installed with the tank body 1, the annular air outlet pipe 913 is close to the outer wall of the tank body 1, and the upper part of the toggle plate 11 is a wider plane.

[0062] The working principle of the forage pest control device provided in this embodiment is as follows:

[0063] First, two motors 803 drive the rotating shaft 802 to open the two closing plates 804 in opposite directions so that the pests can enter the interior of the tank 1, and the two ultrasonic devices 10 are turned on to a specific frequency band to drive away birds and beneficial insects.

[0064] Then, the fan motor 901 is started in the warehouse under good light conditions during the day, and the fan motor 901 drives the fan blades 902 to rotate. The fan blades 902 exhaust gas upward through the three-way pipe 904, and the gas enters from the slot of the tank body 1 through the vent 12 and flows into the fan blade housing 903.

[0065] Then, during the process of upward exhaust, the attractant core tube 906 is blown, and the gas flows through the attractant core tube 906, driving the internal attractant core to volatilize, and the gas flows into the attractant air delivery pipe 912, and is exhausted to the surroundings through the annular air outlet pipe 913. Under good lighting conditions during the day, the effect of the ultraviolet lamp 7 is limited, the pests' sensitivity to light sources is reduced, and their phototaxis is affected. At this time, the volatilization of the attractant can attract the pests to the vicinity of the tank body 1.

[0066] Then, when cleaning is needed, the two motors 803 are started to drive the closing plate 804 to start closing the tank body 1, and then the cleaning process in Example 1 is carried out. In this process, the ring 403 drives the toggle plate 11 to rotate. The toggle plate 11 contacts the first switch plate 908 while following the rotation of the ring 403, and pushes the first switch plate 908 to rotate 90°. At this time, the gas discharged by the fan blade 902 is transferred from the trapping agent air supply pipe 912 to be discharged from the blowing pipe 910. The blowing pipe 910 is connected to the nozzle 911. After the insect plate 21 rotates, the gas blown out by the nozzle 911 cleans the surface of the insect plate 21. In the rotating state, the heavier debris falls into the degradation bag below after flipping, but the smaller debris is not easy to fall off, and the gas blown out by the nozzle 911 assists in cleaning.

[0067] Finally, after the scraper 401 cleans the electric grid 503, it drives the toggle plate 11 to contact the second switch plate 909 during the reset process, and the second switch plate 909 is rotated 90°. At this time, the gas discharged from the fan blade 902 is transferred from the air blowing pipe 910 to be discharged from the trapping agent air supply pipe 912. After the closing plate 804 is opened, the pests enter the interior of the tank body 1 and work normally.

[0068] Finally, when the lure in the lure tube 906 has completely evaporated, the flange 905 can be removed and replaced.

[0069] Compared with the related art, the forage pest control device provided in this embodiment has the following beneficial effects:

[0070] By setting the sealing plate 804 to be completely closed during cleaning, the spread of odor from insect corpses is blocked, the escape of live insects is prevented, and the insect corpses are prevented from falling to the outside and affecting the environment. The fan blades 902 drive the air flow to accelerate the volatilization of the trapping agent, and the gas is evenly diffused through the annular air outlet pipe 913 to attract pests that are not sensitive to light sources, making up for the insufficient efficiency of the ultraviolet lamp during the day and improving the trapping efficiency during the day. The toggle plate 11 triggers the first switch plate 908, and the airflow of the fan blades 902 turns to the air blow pipe 910. The gas is sprayed through the nozzle 911 to remove small insect corpses or debris remaining on the surface of the insect board, thereby improving the cleaning rate. The attractant core tube 906 is replaceable, and the gas enters from the slot of the tank body 1 to assist in bringing the pests into the device.

[0071] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention.
