Seedbed Vaccination Spraying Fertilization Research

Tobacco Mosaic virus is a common kind of disease, cause huge economic losses to our country. Chemical control method is not only the effect not beautiful and improper use will affect the quality of the ecological environment and human survival. Abroad mainly rely on vaccination for the prevention and treatment of virus harm and vaccination machinery has been quite mature. And inoculation equipment in our country, there is no independent property,thus developing a high efficiency automated machinery is imminent.According to the friction mechanism and the development of bionics friction develop machine. Vaccination machine is the core part of the minimally invasive mechanism.Formulate minimally invasive solutions and through the test to determine the best minimally invasive, this article adopted by minimally invasive solution for the mesh for 800 article purpose cloth glued on the motor driven roller in the face of tobacco seedlings in minimally invasive.Tobacco is delicate, in the process of mechanized vaccination if minimally invasive part design is not ignored due to tobacco affect the growth of tobacco seedlings of serious injury and even death. Minimally invasive appropriate parameters are needed, minimally invasive mechanism of the important parameters for emery cloth of the speed and quality of the article emery cloth(width). In this paper, accord to dichotomy test to find articles emery cloth the best speed and emery cloth width. Determine the minimally invasive drum rotating speed is70 r/min, and emery cloth for 3 mm.Minimally invasive solution is determined, based on the 3 d software Proe aided design of the machine. In order to satisfy the daily management of greenhouses smoke seedlings, this article will smoke seedlings of vaccination, spraying, fertilization is an organic whole to seedbed greenhouses smoke seedlings inoculated spraying fertilizer all-in-one daily management services. All-in-one mainly includes frame, walking mechanism, control system,minimally invasive, and chick institutions.Control system is with the aid of the Eclipse this powerful open platform to developmobile phone APP, as the upper machine under the STM32 as a machine takes control from the upper machine. PC control instruction through bluetooth transmission to the machine.Control system mainly realizes the all-in-one vaccination, spraying, fertilizing three kinds of mode conversion and machine of straight ahead, left and right of control.Smoke seedlings of coverage is a major index of this article, for the realization of the inoculation effect of the optimal moisture content in this paper, we study the smoke in the process of seedlings inoculated with coverage. Tobacco moisture content directly affects the machinery for tobacco seedlings inoculated minimally invasive wound, minimally invasive wound directly affect the coverage of tobacco seedlings, moisture content in tobacco and tobacco seedlings inoculated relationship exists. Endoscopic observation of different moisture content of tobacco seedlings with body traumatic wounds and statistics of its coverage to determine the optimal inoculation of tobacco moisture content is 84% ~ 86%.
