Description
Technical Field
The invention belongs to the field of plant protection devices, relates to a pest attracting device, and in particular relates to a wind-force self-adaptive pest prevention and control device.
Background
In the green and organic production modes, yellow/blue plates, insect attracting balls and the like are used as important technical measures for preventing and controlling insect diseases, and an effective means is provided for realizing organic production by reducing the pesticide and controlling insects.
In general, in use, the yellow/blue plate and the insect attracting ball are hung on branches or wood sticks inserted into field soil through iron wires, the mode is used for adjusting the hanging height of different crops, the height of the wood sticks cannot be adjusted, the yellow/blue plate and the insect attracting ball cannot be fixed through iron wire hanging, the yellow/blue plate and the insect attracting ball can swing around with wind, and especially in the field environment, the wind power influence is even more. To solve this technical problem, various holders for fixing yellow plates have been proposed in the prior art, such as the yellow plate supporting device disclosed in CN106172324 a.
Since the yellow board is usually a plane, pests can only be attracted from the front side and the back side, and the yellow board cannot be seen by pests in other directions. To solve this technical problem, CN207400240U discloses a full view yellow plate insect attracting device.
However, the inventors have found that the prior art is unaware of the effect of wind speed on pest behaviour and thus the significant effect of wind speed on yellow board pest attracting effect. In particular, the speed and direction of the wind have an effect on both the transmission of pathogens and pest flight behavior. In general, the pest take-off is facilitated when the wind speed is small, and the pest take-off is inhibited when the wind speed is large. The wind speed also affects the pest migration direction, for example, the wind speed is less than 2m/s, the mythimna separata migrates against the wind, but the wind speed is 3-4 m/s,94.8% of the mythimna separata migrates against the wind, and the migratory locust flies against the wind at the wind speed of 3.3 m/s; when the wind speed exceeds 3.4m/s, the flying is changed into the downwind.
In the process of implementing the present invention, the inventor finds that at least one of the following technical problems exists in the prior art:
1. the existing yellow board attracting device only considers an attracting structure under the windless condition;
2. under the action of breeze, the pests fly along with the wind, the existing installation mode of the attracting plate can not adjust the yellow plate to be a windward side along with the wind, so that the adhesion effect of the attracting plate on the pests can not be fully exerted, and particularly, when the attracting plate is parallel to the wind direction, the pest attracting effect is poor;

The first bearing 600 and the second bearing 700 each use a thrust bearing. The use of the first bearing 600, the second bearing 700 and the balls 101 makes all the friction forces among the base ring 401, the lower column tube 100 and the upper column tube 200 be rolling friction, and improves the rotation sensitivity of the upper column tube 200 and the base ring 401.
The brake unit 500 is installed in the lower column tube 100, and includes a coil spring 510, a brake shoe 520, a spring seat 530, and a return spring 531; the brake unit 500 brakes the upper column tube 200 by rotationally braking the rotation shaft 210.

The wind force is reduced, the brake shoe 520 is separated from the rotation shaft 210 under the return force of the return spring, and the upper column tube 200 can be rotated again under the action of the attraction plate 300.
It should be noted that the rotation of the rotating shaft 210 is not continuously rotated in one direction, but reciprocally rotated at a certain angle, and the higher the repetition frequency, the stronger the vibration of the device is, and the more easily damaged.
