Nighttime protection device for farmland crops

Abstract

The invention discloses a nighttime protection device for farmland crops, and relates to the technical field of agriculture. The nighttime protection device for farmland crops comprises a collection box, a bottom support rod is fixedly mounted on a bottom wall surface of an inner side of the collection box, a base plate is fixedly mounted at a top part of the bottom support rod, a deinsectizationdevice is arranged at a top part of the base plate, and a bearing is arranged at a top part of the deinsectization device. In the nighttime protection device for farmland crops, striking blocks in trapping grooves in an outer sleeve are affected by an impact force to stretch out and move on sliding grooves in corresponding positions; a process that the striking blocks move on the sliding grooves in the corresponding positions is close to a process that frogs spit tongue dues to an influence of an instantaneous acceleration generated by an instantaneous impact, so that insects in the trapping grooves in the corresponding positions are hit by the striking blocks at an instantaneous high speed, thus the lured insects are hit in a capturing mode each time, therefore, an effect of treating theinsects is achieved, and a situation that a luring effect is reduced due to an insect accumulation is avoided.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a night protection device for field crops. Background technique [0002] Crops are a general term for harvestable products that grow on farmland. Since crops are plants, they are usually disturbed and damaged by insects during the growth process, resulting in damage to crops, especially at night. It is the frequent time for insects to appear, and the types of insects are more complicated. In this situation, insect trap lights are usually used to lure insects, thereby limiting insect damage to crops. However, when insects are attracted to a certain number, the insect traps Because insects block the light, the insect-attracting effect of the insect-trap lamp decreases, which increases the density of plant insects near the insect-trap lamp. Therefore, we propose a night protection device for farmland crops. Contents of the invention [0003] The purpose of the present inven...
