Embodiment Construction

[0023] The implementation of the height adjustment system using parameter identification of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] In the past two decades, the application and development of plastic film has been very rapid, and the effect of increasing production and income has been particularly significant. In 1979, small-scale experiments with vegetables as the mainstay began. In 1983, the area covered by plastic film of various crops soared to 629,000 hectares. During the 11 years from 1982 to 1992, the area covered by plastic film was 25.067 million hectares. In 1996, the area covered by plastic film exceeded 100 million mu, reaching 7 million hectares, of which the crops reaching or exceeding 380,000 hectares included 1.761 million hectares of corn, 1.816 million hectares of cotton, 605,000 hectares of rice seedlings, 589,000 hectares of peanuts, and 743,000 hectares of vegetables. 600,000 hectares o...

Abstract

The invention relates to a height adjusting system using parameter identification. The system comprises: a plastic film mulching mechanism, which comprises a rolling wheel body, a plastic film winding roller, a handrail structure, and a pedal type switch mechanism. The rolling wheel body is arranged at the foremost end of the plastic film mulching mechanism, and is used for compressing soil after sowing seeds; the mulching film winding roller is connected with the pedal type switch mechanism and is used for releasing a mulching film under the control of the pedal type switch mechanism; height adjusting equipment is connected with a reel of the mulching film winding roller and used for adjusting the mulching film covering height of the mulching film reel by controlling the height of the reel; and signal mapping equipment is used for determining a corresponding coverage height based on a received representative depth-of-field value. The height adjusting system using parameter identification is compact in design and intelligent in operation. Due to the fact that different plastic film covering heights can be selected according to the depth degree of to-be-covered farmland soil, so that requirements for crop planting are met.

Description

technical field [0001] The invention relates to the field of plastic film covering control, in particular to a height adjustment system utilizing parameter identification. Background technique [0002] Mulch film is the ground covering film, usually transparent or black PE film, and there are also green and silver films, which are used for ground covering to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc. , the function of promoting plant growth. [0003] The mulch looks like a thin layer, but it is quite effective. It can not only improve ground temperature, water, soil, fertilizer and fertilizer efficiency, but also has many functions such as weed control, pest control, drought and waterlogging resistance, salt suppression and seedling protection, improvement of light and heat conditions near the ground, and sanitation and cleaning of products. For those seed...
