Description

Rice planthopper field collecting device

Technical Field

The utility model belongs to the agricultural field especially relates to a field collection device of rice planthopper.

Background

The rice planthopper is the most important pest of rice in China. Especially, brown planthopper has the widest occurrence area and the most serious harm, is one of important barrier factors for rice production, has the characteristics of outbreak, concealment, outbreak and the like, and has the premise of effective prevention and control, namely accurate prediction, and field investigation.

The traditional rice planthopper field investigation method generally adopts a disk shooting method all over the country: the investigator bends over, gently inserts the porcelain plate into the base of the rice cluster with one hand, quickly beats the rice plants 3 times with the other hand, and expels insects and falls off the rice plants, and the quick end plate records the types, insect states and quantity of the rice planthoppers in the rice cluster. The method requires that investigators bend over and beat rice clumps manually, the working strength is high, and meanwhile, sharp rice leaves in the middle and later growth periods of rice often injure hands and faces of the investigators without protection; in addition, the method is not high in accuracy, manual striking human factors are large, and the force of investigators is often uneven; on the other hand, in the process of quickly lifting the porcelain plate from the base, some insects can jump away and fly away, and particularly the adults influencing the key data influence the accuracy of the key data; in addition, during the growth period of rice, particularly in the early growth period of rice, the rice planthoppers are usually mixed and spread by the three planthoppers of the small brown planthoppers, the white back planthoppers and the brown planthoppers, and the low-age nymphs, the high-age nymphs and the adults are mixed and alternate, so that the technical threshold requirement is high for correctly identifying the three rice planthoppers, particularly the low-age nymphs, generally by means of a magnifying lens, a hand-held disk and a hand-held magnifying lens, and the working efficiency is seriously influenced in summer inflammatory seasons. Therefore, a monitoring tool capable of reducing the labor intensity and improving the accuracy is needed in production.

For example, the Chinese patent application No. 201510293344.0 discloses a field investigation and collection device for rice planthoppers, which comprises a tubular cover body, wherein the inner cavity of the cover body is communicated with an exhaust pipe, and one end of the cover body is provided with an opening for rice plant stalks to pass through. Although above-mentioned patent utilizes and produces extremely strong suction with the communicating negative pressure device of exhaust column for the polypide on the internal rice trunk of cover is inhaled the exhaust column along with the air, technical staff carries out the data statistics to the polypide that takes out, has greatly reduced observation personnel's working strength, but discover in actual operation, the size of air current, the orificial position of convulsions, negative pressure device's power all has very big influence to the collection effect, cover internal portion very easily appears because of the inhomogeneous problem that can't fully collect the polypide on the rice trunk that leads to of air current.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a novel field collection device of rice planthopper solves the internal portion of cover that current device exists and easily appears because of the inhomogeneous problem that leads to the polypide on the rice plant fully to collect of air current.

The utility model provides a technical scheme that its technical problem adopted is: a field collecting device for rice planthoppers comprises a cover body capable of containing rice plants, two air bags and an air pump, wherein the two air bags are symmetrically arranged on the left side and the right side of the lower end in the cover body so as to clamp the bases of the rice plants; the air pump is connected with a first air pipe and a second air pipe, the first air pipe is connected with the air bag, the second air pipe extends into the lower part of the cover body, and the outlet of the second air pipe faces upwards; the cover body is also connected with a collecting pipe for collecting the worm bodies. According to the technical scheme, the left side and the right side of the lower portion of the cover body are respectively provided with the air bags, the volume of the air bags is gradually increased when the air pump works, and rice planthopper insect bodies are driven by the air bags in a closed area formed by the air bags and the inner wall of the cover body and move towards the direction of the collecting pipe under the action of air flow of the second air pipe, so that the problem that the insect bodies on rice plants cannot be fully collected due to uneven air flow in the cover body of the existing device is solved.

Further, the air bag is flat and semicircular.

Furthermore, an insect collecting bag is arranged at the outlet of the collecting pipe.

Furthermore, a fastening structure for fixing the air bag is arranged in the cover body.

The utility model has the advantages that:

(1) the utility model discloses an respectively dispose an gasbag in cover body lower part left and right sides, this gasbag forms a variable independent space of relative confined with the cover body, and gasbag volume crescent about aerifing the in-process for the activity space of the rice planthopper polypide body diminishes gradually, and simultaneously under the air current effect that the second trachea produced, the rice planthopper polypide body moves to the collecting pipe direction, realizes the abundant collection of the polypide body, has improved the accuracy of data.

(2) The utility model has the advantages of simple structure, portability, convenient use and lower manufacturing cost compared with the scheme of the prior negative pressure device.

The present invention will be described in more detail with reference to the accompanying drawings and examples.
