Biological control ball releasing device matched with airplane

Abstract

The invention discloses a biological control ball releasing device matched with an airplane, which relates to the field of agricultural plant protection machinery. Two ball releasing devices are arranged at two sides of the airplane, so that the stability of the gravity center of the airplane is guaranteed; when the whole device works, a motor drives outer groove wheels in the left and right ball releasing devices to rotate, and the outer groove wheels drive the balls to reach a cylindrical ball guiding groove, and then the balls are discharged from the ball releasing devices; in addition, the releasing amount of the balls is regulated by regulating the rotating speed of the motor or the length of a ball releasing groove baffle; the left-right space between every two balls reaching the ground is regulated by regulating the size of an air inlet of an air inlet pipeline; the whole device realizes mechanical releasing of natural enemy insects in biological control, so that labor intensity is greatly reduced.

Description

technical field [0001] The invention relates to the field of agricultural plant protection machinery, in particular to a biological control pellet delivery device matched with an aircraft. Background technique [0002] The control of crop diseases and insect pests is an important part of agricultural production and harvest; according to the statistics of foreign experts, if no preventive measures are taken, the damage caused by diseases and insect pests is about 30% of the total output value of agricultural products. Chemical control and mechanical spraying are still the mainstay of plant protection operations. The main method, but it brings huge environmental problems; the United States, the United Kingdom and other member states and regions of the European Community with a relatively high level of agricultural machinery, the effective utilization rate of pesticides has reached 60%-70%, In China, only 30%; China has 1 million tons of pesticide preparations and 100 million t...

Problems solved by technology

[0004] But the release of natural enemy insects mostly adopts artificial fixed-point release, such as patent application number "200610017085. Bag-type bee release device", application number "200620029161.4" is named "Trichogramma box-type bee release device", application number "201210074834.8" is named "a method for sustainable release of parasitic natural enemy insects", application number "201310567933.4" The bee release device or the release device invented by the name "Insect and Bug Release Device and Its Application", the application number "201320407816.7" and the name "A Multipurpose Natural Enemy Insect Mixing Release Device" all need to be placed manually or Hanging in the field, because for the integrated large field, the labor intensity is very high; in addition, the patent application number "201120502819. Method and release device for releasing parasitoids to control pests", application number "201320503873.5" titled "a bee release device suitable for releasing parasitoids in paddy fields to control rice pests", application number "201420451209.5" titled "a device suitable for releasing natural enemies "Insect pest control device" only invented the release device for natural enemy insects, did not indicate how to release them into the field, and did not invent a supporting mechanical release mechanism

[0005] In order to reduce the labor intensity of releasing natural enemies and improve delivery efficiency, the patent application number "201120328245.9" titled "Natural Enemy Releaser for Aircraft" discloses a natural enemy releaser for aircraft, but the structure of the whole device is complicated, and the natural enemy insects are transmitted in the device. The line is long and equipped with two motors, which takes up a lot of space when installed on the aircraft, and the aircraft load increases; in addition, when the natural enemy insects are transported in the device for a long distance, there is no protection, they are easy to be crushed, collided, and the mortality rate is high; the patent The release device disclosed by the application number "201220699049.7" titled "Natural Enemy Release Device for Aircraft" not only fails to protect the natural enemy insects, but also rotates with the storage box, and is thrown to the box wall under the action of centrifugal force, causing a death rate. It is extremely high, and may stick to the wall of the box under the action of centrifugal force and cannot be discharged; and the patent of the present invention "a biological control pellet delivery device for aircraft" not only designs natural enemy insects to place pellets to protect natural enemy insects; and A simple and efficient mechanized delivery device is designed to facilitate the release of natural enemy insects into the field, realizing the engineering of biological control technology, greatly reducing labor intensity while ensuring the survival rate of natural enemy insects
