[0014] The present invention provides a nursery isolation device for forestry pest control, which has the following beneficial effects: (1) The present invention begins to protect the nursery by extending the insect-proof net into place, which can effectively isolate pests in the air and prevent them from contacting the seedlings, thereby reducing the occurrence of pests and avoiding the harm of pests to the growth of the seedlings. The scraper bar contacts the insect-proof net to clean the dust, soil, leaves and insect corpses accumulated on the insect-proof net, preventing the mesh from being blocked and affecting the transmittance of air and light, thereby reducing the function of the insect-proof net. At the same time, insects may leave eggs or feces on the surface of the insect-proof net. Using the scraper bar to clean the net surface can reduce the accumulation of eggs and further prevent the breeding of pests.

[0015] (2) The invention collects the impurities removed when cleaning the insect-proof net by using a scraper rod, which can effectively gather the removed debris together to prevent them from spreading everywhere. At the same time, if these debris are discarded or left in the surrounding environment at will, they may become a breeding ground for pests and diseases. By using a collection box to collect these debris, it is convenient to centrally treat these debris, thereby reducing the spread and breeding of pests and diseases at the source. The rod moves upward to break away from the contact with the block, and then the staff manually pulls the handle to pull out the collection box and dump the impurities at a designated location. The impurities are cleaned up and dumped at the designated location in a timely manner, which helps to keep the environment clean. At the same time, dumping the impurities at a special treatment location can better classify the impurities, which is convenient for subsequent cleaning and resource recovery.

[0016] (3) The invention promotes air flow by rotating the fan blades, helps to take away excess heat, avoids excessive temperatures in the nursery, and thus ensures the healthy growth of plants. At the same time, the fan enhances air circulation and reduces the overly humid environment, which can reduce the frequency of disease occurrence and thus improve the disease resistance of plants. The dust or other impurities on the protective cover are cleaned off by vibration to ensure the normal operation of the fan, thereby improving the air circulation efficiency. At the same time, regular cleaning of the protective cover can reduce the amount of dust that enters the fan, helping the fan to maintain normal operation, reducing the loss of motor 2 and other components, and extending its service life.

At the same time, these debris are randomly discarded or left in the surrounding environment, which may become a hotbed of pests and diseases. By using the collecting box 165 to collect, These debris can be conveniently processed in a centralized manner to reduce the spread and breeding of pests and diseases at the source. After the collection box 165 is full, the staff manually presses the button 167 after work, so that the button 167 moves to the right to contact and push the card rod 168 to start moving upward. The card rod 168 moves upward and breaks away from the contact with the card block 169. Then the staff manually pulls the handle 166 to pull out the collection box 165 and dump the impurities at the designated location. The impurities are cleaned up and dumped to the designated location in time, which helps to keep the environment clean. At the same time, dumping the impurities at a special treatment location can better classify the impurities and facilitate subsequent cleaning and resource recycling.

[0030] During the extension of the insect-proof net 5, the staff starts the motor 171, so that the motor 171 drives the shaft 172 to start rotating, and the rotation of the shaft 172 drives the fan blades 173 to start rotating. The rotation of the fan blades 173 promotes air flow, helps to take away excessive heat, and avoids excessive temperature in the nursery, thereby ensuring the healthy growth of plants. At the same time, the fan enhances air circulation and reduces the overly humid environment, which can reduce the frequency of disease occurrence and thus improve the disease resistance of plants. When the fixed box 162 moves downward, it drives the pressure rod 177 to start moving downward, and the pressure rod 177 moves downward. The rotating rod 175 moves out of contact with the rotating rod 175, and then the rotating rod 175 starts to rotate and reset under the action of spring four. The rotating rod 175 rotates and resets to drive the fixed block 176 to start moving. The fixed block 176 moves to contact and knock the protective cover 174 to make it vibrate, and the dust or other impurities on the protective cover 174 are cleaned off by vibration, ensuring the normal operation of the fan, thereby improving the air circulation efficiency. At the same time, regular cleaning of the protective cover 174 can reduce the dust from entering the fan, help the fan maintain normal operation, reduce the loss of motor 2 171 and other components, and extend its service life.
