Description

Insect prevention device for planted rice Technical Field The utility model relates to the technical field of insect prevention devices, in particular to an insect prevention device for planted rice. Background The insect-proof device for the planted rice is mainly used for protecting the rice from insect damage in the planting process and guaranteeing the yield and quality of the rice. The device can be widely applied to various rice planting areas, and the current device generally needs the following technology in practical application, no matter in large-scale farms or small-scale family farmlands: 1. Efficient trapping and repelling technologies such as special light sources, odor attractants, and sonic repelling devices; 2. Durable and easy-to-maintain materials and structures, and is suitable for different farmland environments and climatic conditions. At present, in order to realize the insect prevention function of the planted rice, various devices, modes and using methods are adopted. According to the insect prevention device for the planted rice, CN208821525U is disclosed, through the mutual matching between a motor with a rotating seat and grinding teeth at the bottom and a shell with the grinding teeth at the inner wall of the bottom, the insect prevention device for the planted rice utilizes an pheromone groove and a trapping lamp to trap the insect entering the inner side of the shell through the trapping hole and is killed by a power grid, a cadaver falls into a slope surface of a guide block to slide into a gap between the rotating seat and the inner wall of the shell, and is smashed by using staggered grinding teeth under the driving of the motor to form a fertilizer for the planted rice, the problem of cleaning the insect at regular time is avoided, the convenience of use is improved, meanwhile, through the matching between a solar panel and a fan blade, when the rotating speed of the fan blade is high, the motor of an alternating current motor is reversed, a storage battery is blocked, the fan blade drives a rotating shaft of the motor to reversely generate electricity, extra electricity storage energy is provided for the storage battery, meanwhile, the rotating seat is driven to rotationally grind by the fan blade, the insect pheromone in the groove is volatilized better, and the insect prevention device for the insect prevention device is stably solved, and the insect prevention efficiency of the planted rice device is improved. However, the above-mentioned mode has a outstanding problem, namely the bracing piece in the above-mentioned device is fixed relatively, lacks the lift regulatory function, can't carry out the altitude mixture control according to paddy field's actual topography and water level variation, and adaptability is relatively poor, when placing the demand in the face of different altitudes, needs to additionally build bearing structure and reaches suitable height, has increased the degree of difficulty of installation and use. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the insect prevention device for planting rice, which solves the technical problems that the supporting rods in the device are relatively fixed, the lifting adjusting function is lacked, the height adjustment can not be carried out according to the actual topography and water level change of a rice field, the adaptability is poor, and when the placing requirements of different heights are met, the supporting structure is required to be additionally built to reach the proper height, and the difficulty of installation and use is increased.
